[0002] Glyphosate is the main raw material for the production of broad-spectrum post-emergence herbicides and is also an important intermediate in the pesticide, medicine, rubber, electroplating, and dye industries. If glyphosate is mixed with water and heated in the presence of equimolar sulfuric acid with an excess of hydrogen peroxide, glyphosate is obtained through a reaction.

[0003] After the reaction, water needs to be filtered from glyphosate. Currently, the filtering method is as Figure 1 shown. A belt filter cloth is provided, and it is circulated and conveyed by a conveyor roller. The belt filter cloth itself has fine filter meshes, so that the water in glyphosate is gradually filtered by the belt filter cloth while being conveyed, and the solid matter remains on the belt filter cloth and is further collected for the next process. However, a small part of the solid matter always adheres to the belt filter cloth. If it is not cleaned regularly, it will block the filter holes of the belt filter cloth and affect the filtering effect of the next cycle of the belt filter cloth. Therefore, a material washing device for the belt filter cloth in the glyphosate production process is needed. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a material washing device for glyphosate production is proposed to solve the problem of blocking the filter holes of the belt filter cloth and affecting the filtering effect of the next cycle of the belt filter cloth.

A first guide roller for pressing down the belt filter cloth is installed on the left side of the bottom of the bracket. A cleaning pool is installed below the first guide roller. A cleaning liquid is arranged in the cleaning pool. A brushing assembly is installed in the cleaning pool. A second guide roller for lifting the belt filter cloth is installed on the right side of the bottom of the bracket. A filter pocket is arranged below the second guide roller. A flushing assembly is arranged above the filter pocket.

[0007] Preferably, the brushing assembly includes a first mounting frame, a first brush roller, and a second brush roller. A driving motor is fixedly installed on the first mounting frame. The driving motor drives the first brush roller and the second brush roller to rotate. The first brush roller and the second brush roller are both rotatably installed on the first mounting frame.

[0008] Preferably, the flushing assembly includes a clean water tank, a second mounting bracket, a first spray head and a second spray head. A water pump is installed in the clean water tank, and the water pump is respectively connected to the first spray head and the second spray head through water pipes. The first spray head and the second spray head are both fixedly installed on the second mounting bracket.

[0009] Preferably, a scraping plate is fixedly installed on the left side of the bracket, and the scraping plate is attached to the surface of the belt filter cloth.

[0010] In summary, the beneficial effects of the present utility model are as follows: A material washing device for glyphosate production provided by the present utility model presses the belt filter cloth into the cleaning tank through the setting of the first guiding roller. The cleaning liquid in the cleaning tank rinses the belt filter cloth.
