Screw extrusion type sludge distributing machine

Abstract

The invention relates to a screw extrusion type sludge distributing machine. The machine comprises a supporting frame, a driving mechanism mounted on the supporting frame, a movable vehicle-mounted mechanism mounted on the supporting frame and a screw extrusion mechanism mounted on the vehicle-mounted mechanism; the driving mechanism for driving the vehicle-mounted mechanism to reciprocate linearly along the supporting frame is connected with the vehicle-mounted mechanism; an open space for falling of sludge is arranged in the supporting frame; the screw extrusion mechanism having a downward sludge extruding function is located above the open space of the supporting frame; a barrel is mounted on the vehicle-mounted mechanism; a screw is arranged inside the barrel; a screw driving device for driving the screw to rotate is mounted at the upper part of the barrel; a feeding pipe communicating with the inside of the barrel is mounted on the barrel; an extruding machine head is arranged at the lower end of the barrel; and a detachable fifth flange is arranged at the lower end of the extruding machine head. The distributing machine can mash, mold and extrude the sludge, can evenly disperse the extruded sludge on a drying unit at the same time and belongs to the technical field of sludge treatment.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to a screw extrusion sludge distribution machine. Background technique [0002] After preliminary treatment of sewage, sludge will be produced. The sludge with high water content must be dried first, and then further treated. If the sludge distribution is uneven, the drying efficiency will be greatly reduced, and at the same time, it will easily cause sludge run-off, which will affect the on-site operating environment. [0003] The patent application with the publication number CN204237696 discloses a sludge uniform distribution device. The distribution method of the device is that the sludge first passes through the sludge spreading shaft, then passes through the sludge feeding bin body, and then reaches the first sludge crushing shaft, the second sludge crushing shaft, and finally through the sludge paving shaft, in which the outer peripheries of the first sludge crushin...

AI Technical Summary

Problems solved by technology

However, this device also has the following disadvantages: 1. If the feed of the sludge is piled up at the beginning, the sludge cannot be evenly covered on the filter cloth under the action of the paving shaft.

2. Since the spiral belt of the crushing shaft and the flattening shaft with scrapers are placed horizontally, they are close to the filter cloth, which tends to cause greater friction with the filter cloth, which accelerates the wear of the parts and increases the energy consumption

3. Since the four motion axes use independent power sources, a lot of power is required, and the energy consumption is even greater
