摘要:
Scrap of thermosetting plastics is reclaimed and recycled by an integrally combined apparatus which includes a device for pulverizing and atomizing the scrap, and a device for blending fine powder of the scrap with virgin material of thermosetting plastic. The device for blending includes a feed screw of constant revolution speed for conveying the fine powder of scrap and a variable speed feed screw for conveying virgin material in order to obtain high blending performance.

The apparatus comprises a milling machine including a heated rotatable drum connected to means for supplying coarsely crushed coal and preheated oil to the drum wherein the coal becomes finely ground and homogeneously mixed with the oil, and having a discharge duct rotatably connected to the drum and slidably connected to a stationary discharge tower in which the coal/oil slurry is separated from water evaporated from the coal during milling.

A mixer with a substantially conical mixing chamber supported vertically with its apex lowermost. A tapered auger is situated in the mixing chamber and mixer drive is provided at the base of the mixing chamber. The narrowmost end of the tapered auger is connected to the drive such that the auger rotates around its own axis and its upper end rolls around the upper periphery of the mixing chamber.The upper end of the auger has a wheel to allow the auger to freely roll around the upper periphery of the mixing chamber and to insure that the auger does not contact the walls of the mixing chamber. The wheel is held in contact with the upper periphery of the mixing chamber under the action of the weight of the auger.

An apparatus and method for treating for disposal organic waste material carried within a sludge, by adding to the sludge an alkali metal silicate and a setting agent, is disclosed. The apparatus includes several mixers, each having a trough with an input end and a discharge end, at least one rotatable shaft mounted longitudinally along the trough, a plurality of blades mounted to the shaft, and a drive for rotating the shaft. The sludge is deposited within a first mixer, and then directed from the mixer into a tank. A series of chopper pumps recirculate the sludge into the tank, and alternatively, the sludge may be passed through an additional mixer. Leaving the tank, the sludge is directed into a second mixer at its input end. Water is introduced at the input end, and a setting agent is added along the trough at a point adjacent the input end. Further along the trough, an alkali metal silicate is introduced. The mixture is recovered from the second mixer, and carried to a remote location for setting.

Scrap of thermosetting plastics is reclaimed and recycled by an integrally combined apparatus including means for pulverizing scrap into atomized powder and means for mixing and agitating the atomized powder with a virgin material at a desired ratio. An improved recycling apparatus for thermosetting scrap comprises compactly a pulverizer, an atomizer, a mixing device to mix uniformly atomized powder with virgin material, and a purifying device for Noxious gas generated during pulverizing process.
