Embodiment 1

[0031] see Figure 1-4, a horizontal screw conveyor for a plate and frame filter press, comprising a screw auger 1 and an auger shell 2 located outside the screw auger 1, the upper part of the auger shell 2 on the current screw conveyor is set into The material guide sleeve and the feed guide sleeve are located at the lower part of the filter plate frame arranged and distributed in the plate and frame filter press. The auger rotates to transfer and discharge the filter cake; because the screw conveyor itself has the wear phenomenon of the auger blade 12 and the inner wall of the auger shell 2, it is often used for light material transmission or a transmission environment with a certain concentration of fluid; after pressure filtration The filter cake has a certain water content, so it is wet and agglomerated, and the overall fluidity is poor, which increases the resistance of transmission in the auger shell 2, thus increasing the axial force of the auger 1, and The filter cak...

Embodiment 2

[0033] see Figure 5 The difference with Embodiment 1 is that the auger housing 2 is composed of a middle cylinder 21 in the middle and guide cylinders 22 located at both ends of the middle cylinder 21. The discharge pipe 211 on the auger housing 2 is located at the bottom of the middle cylinder 21. The auger blades 12 on the auger 1 are divided into two sections and distributed symmetrically, that is to say, the auger 1 rotates in one direction so that the filter cake can be transported to the middle of the auger shell 2 and discharged from the discharge pipe 211; further described as a guide cylinder 22 is conical and the large end is fixedly connected to the middle cylinder 21. The two sections of auger blades 12 are conical in shape. The taper of the auger blade 12 is the same as the taper of the guide cylinder 22. The auger shaft 11 is mentioned in embodiment 1. Relative to the auger shell 2, the axial buffering movement is possible. In this embodiment, when the auger 1 i...

Abstract

The invention discloses a horizontal spiral conveyor for a plate-and-frame filter press. The horizontal spiral conveyor comprises a spiral auger and an auger shell located outside the spiral auger. Inthe present invention, axial buffer devices are fixedly arranged at the two ends of the auger shell; each axial buffer device comprises an annular mounting base, a traction plate, supporting plates,a circular positioning plate, a guide sleeve, a first reset spring and a second reset spring. One side of each supporting plate is in sliding fit with one end of the annular mounting base; the slidingdirection is the same as the length direction of each supporting plate; at least three supporting plates are uniformly distributed in the circumferential direction relative to the annular mounting base; the length direction of the supporting plates is the same as the radial direction of the annular mounting base; and the circular positioning plate is located at one end of the annular mounting base, and the outer surface wall of the circular positioning plate is hinged to the other side of the supporting plates through the traction plate. With the arrangement, the axial buffering devices can assist the spiral auger in conducting axial buffering movement relative to the auger shell, and the phenomenon of frequent buffering is avoided.

Description

technical field [0001] The invention relates to the technical field of filter press conveying, in particular to a horizontal screw conveyor for plate and frame filter presses. Background technique [0002] The plate and frame filter press is a kind of intermittent solid-liquid separation equipment. It is composed of filter plates and filter frames to form a filter chamber. The solid and the liquid are separated, and the filter cake after being filtered by the plate and frame filter press is naturally dropped from the filter plate, and the arranged and distributed filter plates are usually opened one by one, so the falling method of the filter cake is single. The directions fall in order. [0003] At present, belt conveyors are commonly used to transport dropped filter cakes, but belt conveyors are prone to environmental pollution, so spiral ring conveyors are gradually replacing belt conveyors; The cake contains a certain amount of water and has poor fluidity. When the scr...
