Device for cleaning filtering cloth of belt press filter for alcohol mash

Abstract

The invention provides a device for cleaning filtering cloth of belt press filter for alcohol mash. The device comprises a roller with two ends for supporting the filtering cloth, a water spraying pipe is arranged on the filtering cloth, a three-way pipe is arranged at each of two ends of the water spraying pipe, and a gate convenient for dredging is mounted on each of the three-way pipes at two ends of the axial direction of the water spraying pipe; a system water incoming pipe is arranged at another through port of a three-way valve, a plurality of water spraying ports are formed in the water spraying pipe at intervals, diameter of each water spraying port is 2mm, and the water spraying pipe is a PVC water pipe. When the gate is opened, a cleaning head of a cleaning rod or cleaning wateris utilized to clean the water spraying pipe. The device has the advantages that one-way feeding of the water spraying pipe is changed into two-way feeding, and feeding direction is changed constantly, so that scaling, blocking and damaging of the water spraying ports of the water spraying pipe are reduced; the water spraying pipe is the PVC water pipe, so that cost can be reduced, and easiness in drilling is realized; by designing the gate, convenience is brought to cleaning, and cleaning can be realized by using the cleaning water or the cleaning head.

Description

technical field [0001] The invention belongs to the technical field of cleaning equipment, in particular to a cleaning device for a filter cloth belt of a belt filter press used for producing alcohol. Background technique [0002] In reality, the filter press alcohol mash mostly uses a belt filter press to dehydrate the sludge. The hydrated sludge is transported to the sludge mixing tank through a sludge pump, and at the same time, a coagulant is added to fully mix and react, and then flows into the belt press. In the mud distributor of the filter machine, the sludge is evenly distributed on the filter cloth belt in the gravity dehydration area, and under the guidance of the water-guiding rake teeth and the action of gravity, the sludge moves with the filter cloth belt and quickly removes the dirt. Free water in mud. [0003] During the working process of the belt filter press, the filter cloth belt needs to run continuously. In order to keep the filter cloth belt clean and...

AI Technical Summary

Problems solved by technology

The existing cleaning device has been used for a period of time, and the nozzle is often blocked by the splashed sludge and cannot discharge water, which greatly affects the cleaning effect of the filter cloth belt, and it is difficult to ensure the dehydration effect of the sludge

[0004] However, in the pressing of alcohol mash, since the cleaning water is the system water, and the cleaning water contains certain cassava fibers, the nozzles are more likely to be fouled, blocked and damaged.

The nozzle is expensive, and it is very inconvenient to disassemble and assemble, which affects normal production
