A screw extrusion sludge distribution machine

Abstract

The invention relates to a screw extruding sludge distributing machine, comprising a supporting frame, a driving mechanism installed on the supporting frame, a mobile vehicle-mounted mechanism installed on the supporting frame, and a screw extruding mechanism installed on the vehicle-mounted mechanism; The driving mechanism that drives the vehicle-mounted mechanism to reciprocate along the support frame is connected to the vehicle-mounted mechanism; the support frame is provided with an open space for sludge to fall; the screw extrusion mechanism with the function of extruding sludge downward is located in the support frame above the open space. The barrel is installed on the vehicle-mounted mechanism, the screw is placed inside the barrel, the screw drive device for driving the screw to rotate is installed on the upper part of the barrel, and the feed pipe connected to the inside of the barrel is installed on the barrel, the extruder The machine head is arranged at the lower end of the barrel, and the lower end of the extruder head is provided with a detachable fifth flange. The distributing machine can not only crush, shape and extrude the sludge, but also spread the extruded sludge evenly on the drying unit, belonging 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
