摘要:
A dewatering device for aggregate product can be used to retro-fit existing aggregate product dewatering facilities in order to more efficiently capture product. The dewatering device can be movable to allow for the portability of the device relative to existing dewatering facilities. The device is adapted to receive a slurry of aggregate product and water and to vibrate to dry the aggregate product. A recycle system is included to receive any fines that may otherwise be lost by the system. The recycle system captures the fines and redirects them back towards the vibrating process of the vibrating device to direct them towards an exit of the vibrating device in order to use said fines as well as the other dewatered aggregate product. The portability of the device allows the device to be used with the existing facilities without the need to completely replace existing components for dewatering aggregate product.

A device for heating or cooling of bulk material including two pairs of vibrating chutes, with each pair being formed of two oppositely inclined chutes mounted one above the other and with each pair being equipped with a unidirectional vibrator, and with vibrating chutes of each pair being connected with a plurality of pairs of oppositely inclined articulated bars, and with vibrating chutes being equipped with flow ducts connected with each other in such a way that heating or cooling medium flows in the flow ducts of the vibrating chutes of each pair in the same direction so that in one chute the directions of flow of the heating or cooling material coincide with the flow of bulk material, and in the other chute they flow in opposite directions.
摘要:
An energy-saving type solar-heated drying apparatus for drying various types of matter, which utilizes a drying room surrounded by a solar-heat transmitting/absorbing wall. In the drying room, the matter is deposited on an elongated drying cage while exposed to a dry hot air produced by the solar heat. During drying treatment of the matter, the matter is moved from a supply side of the drying cage to a discharge side of the same in a longitudinal direction of the drying cage by means of a stirring/mixing transporter by which the matter is stirred/mixed while moved from the supply side to the discharge side of the drying cage. The dry hot air produced in the drying room under the influence of the solar heat is drawn into the drying cage, passing through the matter deposited thereon so as to evenly and effectively dry the matter.

A dewatering apparatus having a delivery zone and a drying zone separated by a weir is disclosed. The delivery zone is provided with a porous floor plus an associated drain and the drying zone has a vibrating porous surface above an associated plenum chamber. The plenum chamber is connected to a source of a hot gaseous fluid.

Apparatus for drying or cooling bulk material of the type which includes a vibratory conveyor through which the bulk material is transported includes the improvement wherein a plurality of partition members are provided in the conveyor so as to define between them a plurality of channels, the partition members preferably having fin-tube configurations whereby the same carry a thermal transfer fluid for facilitating the heat treatment of the bulk material. Apparatus for screening the fine portion of the bulk material is provided in the channels which preferably narrow in the direction in which the bulk material is transported so that the fine portion of the material receives less thermal treatment.

Particulate treatment apparatus includes structure defining a particle treatment zone including a conveyor defining an imperforate lower particle treatment zone boundary. A chamber above the particle treatment zone receives a body of liquid, and means are provided for creating a zone of vapor within the chamber above the body of liquid. Nozzle tubes extend through the lower wall of the chamber and are disposed along the length and across the width of the treatment zone. The upper ends of the nozzle tubes extend above the level of liquid in the chamber while the lower ends of the tubes are disposed adjacent the imperforate transport surface of the conveyor. Vapor flows from the vapor zone through the tubes downwardly against the conveyor surface and fluidizes particles on the conveyor with concurrent vapor exchange so that the particulate material entrains a substantial amount of vapor as it is transported through the treatment zone.

An improved method and apparatus for forming chopped glass fiber strands is disclosed. The improvement comprises a vibratory conveyor under a drying apparatus for said glass fiber strands which is insulated such that cold spots do not develop on the tray adjacent the glass fiber strands. Preferably, the tray is formed of two sections, one inside the other, having an airspace therebetween along their lengths and having a spacer between the lips of the sections.
摘要:
The present conduit or trough for a vibratory conveyor is constructed especially for transporting and/or treating bulk materials such a wood chips or the like. The trough or conduit is provided inside thereof with partition plates extending substantially across the transport direction. These partition plates take up part of the depth of the trough or conduit and may be arranged at an angle relative to the transport direction. Baffles may be arranged in the conduit or trough to extend away from the partition plates and substantially in the transport direction.
摘要:
A washer uses a vibrated feed element having a pile material on its upper surface so that resilient resin bristles of the pile incline from the vertical toward the direction of feed and vibrate against objects to move the objects through the washer. Spray nozzles direct a liquid washing spray against the objects, and a through opening in the feed element allows the washing liquid and material washed from the objects to flow into a drain underneath the feed element. The pile has a groove pattern to aid the flow of washing liquid and material washed from the objects to pass through the pile and through the openings in the feed element to the drain. A dryer having a similar vibratory pile feed element can receive objects from the washer and blow warm air on them to dry them off, and the pile feed elements simplify the feeding and facilitate the washing and drying in the relatively harsh and wet environment.
摘要:
A reciprocating grate conveyor such as that used in a heat exchanger particularly adapted for cooling granular material such as cement clinker with the improvement of an apparatus for balancing the load on the drive mechanism. The conveyor includes a series of grates with movable grates alternating with fixed grates. The grates are mounted on a frame which is secured to wheels which ride on incline tracks. Means are provided for reciprocating the frame and thus, the movable grates. A weight arrangement is pivotally connected to the conveyor support structure for exerting a force on the movable grate support frame in the direction of material movement.
