Screw propelling type high-pressure solid-liquid separation machine

Abstract

The invention puts forward a screw propelling type high-pressure solid-liquid separation machine. A screw extrusion propelling rod is longitudinally mounted in a protection cover of the separation machine; a screen is mounted on the periphery of the screw extrusion propelling rod; the screen is fixedly connected with the protection cover through a screen reinforcing frame; the screw extrusion propelling rod is divided into two discontinuous sections; a through shaft of the screw extrusion propelling rod is sleeved with a plurality of replaceable loose-joint shaft sleeves; and a secondary extrusion section of the screw extrusion propelling rod and the plurality of replaceable loose-joint shaft sleeves can be taken down from the through shaft to change positions. The problems that blockage of materials is caused easily due to the fact that the section of the screw extrusion propelling rod and the section of the protection cover are changed from big to small, the equipment loss is high during extrusion, the damage caused by the materials to the screen is high during extrusion and equipment is required to be maintained frequently in the prior art are solved. According to the screw propelling type high-pressure solid-liquid separation machine, the screw extrusion propelling rod and the protection cover adopt the non-variable-section design, a separation zone is designed for buffering, thus the energy consumption is lower, and the dehydration process is smoother.

Description

technical field [0001] The invention relates to a screw propulsion high-pressure solid-liquid separator, which belongs to the technical field of solid-liquid separation devices. Background technique [0002] The production of cow bedding requires the use of cow manure, and the manure needs to be treated in order to produce sterile cow bedding. The solid-liquid separation process is an indispensable technical link in the process of livestock and poultry manure treatment to meet the requirements of harmlessness and resource utilization. At present, the solid-liquid separation technology at home and abroad mainly needs two solid-liquid separators to uniformly dehydrate finely divided materials with high moisture content (>80%) into materials with low moisture content (about 55%). The high-power solid-liquid separator first performs primary extrusion on the material with a moisture content of more than 80% to reduce the moisture content of the material to about 70%, and then...

AI Technical Summary

Problems solved by technology

[0004] The present invention solves the problem that the energy consumption of the dehydration process of the solid-liquid separator in the prior art is very large, and the production efficiency of the primary and secondary solid-liquid separators is not easy to match. The automatic coordination of the detection system increases the cost of equipment and the probability of equipment failure in the production process. In the actual production process, because the cross-section of the screw extrusion push rod and the protective cover changes from large to small, it is easy to cause material blockage. Moreover, the energy consumption of the machine is large, the extrusion process has a great loss on the equipment, and the material in the extrusion is also very damaging to the screen, and the equipment needs frequent maintenance. A screw-type high-pressure solid-liquid separator is proposed. The push rod and protective cover adopt non-variable cross-section design, and the partition area is designed as a buffer, which avoids the machine stuck situation caused by material blockage caused by the previous variable cross-section design, lower energy consumption, and smoother dehydration process
