Embodiment 1

[0031] refer to Figure 1~4 , is the first embodiment of the present invention, which provides a filter cloth washing device for a vacuum belt dehydrator, including a nozzle assembly 100 and a water inlet assembly 200 . The nozzle assembly 100 includes a spray head 101 and a fixed pipe 102 , and the spray head 101 is rotatably connected to one end of the fixed pipe 102 . The water inlet assembly 200 includes a water inlet pipe 201 and a first connecting pipe 202 , one end of the first connecting pipe 202 is connected to the water inlet pipe 201 , and the other end is connected to the end of the fixed pipe 102 away from the shower head 101 . Through the above configuration, the water inlet assembly 200 provides a water source, and the nozzle assembly 100 sprays water on the filter cloth through the rotatable spray head 101 .

[0032] Further, one end of the nozzle 101 is provided with a plurality of nozzle holes 101a, the other end of the nozzle 101 is provided with a steering...

Embodiment 2

[0039] refer to Figure 5 , is the second embodiment of the present invention, which is based on the previous embodiment, specifically, it also includes an air intake assembly 300 . The air intake assembly 300 includes an air intake pipe 301, a second connecting pipe 302 and an air intake joint 303. One end of the second connecting pipe 302 is connected to the air intake pipe 301, and the other end is connected to the air intake joint 303. The air intake joint 303 is far away from the second connecting pipe 302 One end of is connected with fixed pipe 102. High-pressure gas is passed into the air intake pipe 301, and finally into the nozzle 101 to increase the water pressure.

[0040]Further, an air inlet 303 a is provided in the air inlet joint 303 , and a seal 304 is provided on the side of the air inlet 303 a close to the fixed pipe 102 , and the seal 304 is connected to the inner wall of the fixed pipe 102 through a torsion spring 305 . There are two sealing elements 304,...

Abstract

The invention discloses a filter cloth flushing device of a vacuum belt dehydrator. The filter cloth flushing device comprises a nozzle assembly and a water inlet assembly. The nozzle assembly comprises a spray head and a fixed pipe, and the spray head is rotationally connected to one end of the fixing pipe. The water inlet assembly comprises a water inlet pipe and a first connecting pipe, one end of the first connecting pipe is connected with the water inlet pipe, and the other end is connected with one end of the fixed pipe away from the nozzle. According to the filter cloth flushing device for the vacuum belt dehydrator, by arranging the rotatable spray head and an air inlet assembly, the spraying angle of the filter cloth flushing device for the vacuum belt dehydrator can be conveniently adjusted, and meanwhile an air inlet pipe connector has the water return preventing function and the compressed air adjusting function.

Description

technical field [0001] The invention relates to the technical field of cleaning tools, in particular to a filter cloth washing device for a vacuum belt dehydrator. Background technique [0002] The vacuum belt dehydrator is an important equipment in the wet desulfurization system. The dehydrator is composed of a rubber filter belt, a vacuum box, a driving roller, a filter cloth washing device, and a filter cloth deviation adjustment device. It is an efficient equipment that makes full use of material gravity and vacuum suction to achieve solid-liquid separation. The filter cloth washing device is particularly important in the belt dewatering machine. The filter cloth cannot be effectively regenerated, and if it is not cleaned, the filter residue will gradually stick to the drum, causing the filter cloth to wrinkle and seriously deviate, and the filter cloth will also be severely blocked soon. , the filtration rate drops rapidly, the moisture content of the filter cake incre...
