Laminated spiral type dewatering machine capable of inputting mud from tail end

Abstract

The invention provides a laminated spiral type dewatering machine capable of inputting mud from a tail end. The laminated spiral type dewatering machine comprises a solid-liquid separation part which is formed by arraying a fixed ring and a movable ring in a staggered manner, at least one spiral shaft which penetrates through the solid-liquid separation part, a mud outlet which is located at a front end of a dewatering machine main body and a mud inlet which is located at the tail end of the dewatering machine main body, wherein the solid-liquid separation part is supported through a plurality of supporting plates; the tail end of the spiral shaft is supported by a shaft sleeve; the shaft sleeve is fixedly arranged on the supporting plate which is fixedly arranged at the tail end of the dewatering machine main body; the mud inlet is located on the supporting plate which is located at the tail end of the dewatering machine main body and is located above the shaft sleeve; the mud inlet is connected with the solid-liquid separation part through a mud feeding structure. According to the laminated spiral type dewatering machine provided by the invention, the mud feeding structure part can also be used for filtering and the length of the mud feeding structure is less than that of a sleeve in the prior art, so that the dewatering machine with the spiral shaft with the same length has higher filtering efficiency; a sleeve does not need to be additionally welded so that the machining difficulty is small and the cost is low.

Description

【Technical field】 [0001] The invention belongs to the technical field of sludge treatment equipment, and in particular relates to a stacked spiral dehydrator with sludge feeding from the tail end. 【Background technique】 [0002] Chinese invention patent 200780018706.9 discloses a stacked screw type solid-liquid separation device, which is equipped with a plurality of adjacent fixed rings and a solid-liquid separation part of a plurality of movable rings arranged between the adjacent fixed rings, and a solid-liquid separation part that passes through the At least one screw extending from the solid-liquid separation part, the movable ring is used to push the above-mentioned movable ring through the rotating screw, and at the same time, the object to be treated that enters the solid-liquid separation part is directed towards the side of the solid-liquid separation part through the rotating screw The filtrate separated from the object to be processed passes through the solid-liq...

AI Technical Summary

Problems solved by technology

But there is following shortcoming in this mud inlet box structure: (1), because mud inlet 5 is on the top, so will make a sleeve 4 that can accommodate down mud inlet pipe, this part is only used for mud inlet, cannot implement filtering

Therefore, with the screw shaft of the same length, the filter effect of the dewatering machine with mud entering above is slightly worse; (2), when the support plate 3 at the tail end of the solid-liquid separation part 1 is welded with the sleeve 4, due to the realization of the sleeve 4, The concentricity of the solid-liquid separation part 1 and the shaft sleeve 6 is difficult to process, easily deformed, and the precision is not high, which will affect the subsequent overall assembly

(3), the processing cost is expensive
