Abstract: The gas outlet of a pipe or other sparging device is encompassed by a cover or cap which is located between the gas outlet and the mixing impeller at the bottom of a vessel. The cap is closed at the top and has a side wall so that the gas bubbles disperse around the lower rim of the wall. The wall may be non-symmetric, such as square in cross section, so as to be at different radial positions with respect to the gas outlet. The gas bubbles, even if released in pulses are distributed spatially and in time. The lower rim is preferable serrated (as a saw tooth edge) with the teeth being of different height, thereby further spreading the distribution of the bubbles as they are dispersed. The overlap or distance between the rim and the gas outlet is such that a sufficient quantity of gas is confined around the outlet to damp pressure pulsations when the pressure of the gas at the outlet does not significantly exceed the hydrostatic pressure at the outlet into the liquid. It is believed that the cap defines an acoustic filter which damps and effectively reduces pressure pulses. A turning cone below the top of the cover and facing the outlet may be used to facilitate more uniform distribution of the gas bubbles.

Abstract translation: 管或其他喷射装置的气体出口被位于容器底部的气体出口和混合叶轮之间的盖子或盖子包围。 盖在顶部封闭，并具有侧壁，使得气泡分散在壁的下边缘周围。 壁可以是非对称的，例如横截面的正方形，以便相对于气体出口处于不同的径向位置。 气泡即使以脉冲方式释放也在空间上及时分布。 下边缘优选是具有不同高度的齿的锯齿形（作为锯齿边缘），从而在分散时气泡的分布进一步扩大。 边缘和气体出口之间的重叠或距离使得当出口处的气体的压力不显着超过出口处的液体静压力时，足够量的气体被限制在出口周围以抑制压力脉动 。 据信盖子限定了一个声学滤波器，它可以抑制和有效地减小压力脉冲。 可以使用在盖的顶部下方并面向出口的转动锥体来促进气泡的更均匀分布。

Abstract: A mixer gearbox assembly for driving a mixer shaft capable of receiving either a complete electric drive motor on a first face of the gearbox housing for operatively coupling with a first end of a long cross-shaft in the housing, or alternatively a partial electric drive motor on a second face of the gearbox housing for operatively coupling with an opposite end of the cross-shaft. In an alternative configuration for use with only a partial motor, an assembly containing otherwise identical components is provided with a short cross-shaft replacing the long cross-shaft, which short shaft is supported by a single bearing and is colinearly matable only at the outer end thereof with the drive shaft of a partial electric motor. The rotor and short shaft act as a unitary structure when assembled. The alternative configuration can reduce the cost of manufacture of the gearbox assembly through elimination of a motor bearing, a shaft bearing, and a long cross-shaft, and also this configuration eliminates the usual motor pedestal and its coupling, and through use of all other parts identical with those of the alternative-motor assembly.

Abstract: A system for automatically centering and rigidly retaining a mixer shaft in a mixer drive. A hollow quill in a mixer drive is provided with an axial bore having a first diameter along a central portion thereof and tapering linearly and axially in opposite directions away from the central portion with increasing diameter to define a pair of opposed conical portions of the axial bore on either side of the central bore. A smooth-surface cylindrical mixer shaft inserted into the bore is retained by the tightening of upper and lower tapered cylindrical locks which are slidable along the mixer shaft and have conical outer surfaces which are matable with the upper and lower conical portions of the quill bore. The locks, when urged into wedged relationship between the shaft and the quill bore, automatically center the shaft in the quill in rigid retention. The upper end of the shaft is provided with a thrust plate secured by throughbolts into the quill to press the upper lock into locking relationship. At the lower end of the quill, a bearing retainer ring threaded onto the outer surface of the quill is bored to receive bolts extending through a flange on the lower lock to press the lower lock into locking relationship. The rigidity of the lock increases the first critical frequency of the mixer system and therefore permits operation at high speeds, including rotational frequencies greater than the first critical (natural) frequency of the mixer system.

Abstract: A mixer assembly including a driven hollow quill having first and second conical portions in an axial bore and being adapted to receive and mate with a mixer shaft assembly including a mixer shaft having a conical chamfer to mate with the first conical portion and a quill shaft disposed on and removable from the end of the mixer shaft. The quill shaft has a threaded aperture which cooperates with a jack screw rotatably mounted within the quill bore to draw the conical chamfer into preloaded centered relationship with the first conical portion of the quill bore. A tapered sleeve lodged between the mixer shaft and the second conical portion of the quill bore distributes radial loads on the shaft over a large area of the quill, thereby preventing damage to the shaft and quill. A seal assembly on the mixer shaft isolates the housing from the interior of the vessel. The seal is readily removed for replacement. First, the tapered sleeve is released from the second conical portion. Then the jack screw is rotated to drive the mixer shaft assembly axially from the quill bore. When the mixer shaft is free of the seal assembly, the shaft is secured to the vessel wall. The quill shaft is disconnected from the mixer shaft, and the jack screw is counter-rotated to withdraw the quill shaft from the seal assembly, permitting the seal assembly to be removed in a radial direction from the mixer assembly.

Abstract: A method for making an end connection for a shaft made of composite material, which accommodates for differences in stiffness, thermal expansion, and chemical resistance between the shaft and the member connected thereto and operates under oscillating torque, thrust, and bending loads, and also provides for manufacturing flexibility in enabling the shaft and connection to be produced as separate parts which are formed when final assembly is to occur. The connection has a male insert which is inserted into the end of the composite shaft. Axial and circumferential grooves are cut in the surfaces of the male insert and the shaft. These grooves are aligned to form circumferential and axial keyways which intersect each other. Material is injected into the keyway and polymerizes to form structural keys which transmit the thrust and torque, while locking the insert member and the shaft permanently together. The bending loads are transmitted through the tight fit extending axially between the composite shaft, insert member and keys. The radial thickness of the end of the shaft, the amount and orientation of the reinforcing fibers therein and the insert are matched so that their stiffness index approximately match. The composite shaft may be connected to a mixing impeller to provide a reliable support and drive therefor.

Abstract: Apparatus for mixing particulate material carried in separable containers or process modules rotated with the longitudinal axis thereof at an angle other than 90.degree. to the axis of rotation thereof so that the container rotates asymmetrically with respect to the longitudinal axis thereof. The containers have mixing or process bars rotatably mounted therein and extending also at an angle other than 90.degree. so as to be horizontal when the container is in position for asymmetrical rotation during mixing operations. A docking station of the apparatus has a column connected to the drive shaft at the angle other than 90.degree., an upper arm and a lower arm which is connected to the column and to actuators which tilt the lower arm from a horizontal, container receiving position to a position essentially parallel to the upper arm for clamping the container therebetween. A coupling, between the mixing bar and a shaft which rotates the bar, has a detent which provides for automatic engagement and alignment without manual intervention.

Abstract: Improved draft tube mixing apparatus having one or more of the following features: (a) controlled circulation at the inlet of the tube which allows operation at reduced submergence by preventing formation of a vortex; (b) an additional passage for controlled flow into the draft tube along its length to allow operation without the tube being entirely submerged; (c) the recovery of dynamic energy from the flow at the outlet of the tube by wide area diffusion without separation from the walls of the tube in the diffusing region thereof; (d) improved guidance of radially directed to axially directed flow at the inlet of the draft tube for efficient axial pumping by the impeller by maintaining generally uniform axial flow velocity radially of the impeller; and (e) separation of coarse and fine particles in suspension in the tank to allow selective draw-off of the coarse and/or fine particles thereby increasing efficiency of mixing.
