DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-4 , a urea aqueous solution filtering device is provided, which aims to solve the problem of difficult to filter impurities when filtering the urea aqueous solution, and the problem of excessive loss of the urea aqueous solution. The specific embodiments are as follows:

[0026] Embodiment 1

[0027] The top of the shell box 10 has an opening, through which the urea aqueous solution can be transported to the inner cavity of the shell box 10 .

[0028] The liner rod 20 is located in the inner cavity of the shell box 10 , and a vertical groove 21 is provided on the liner rod 20 . The filter component 30 includes a cylinder 31 and a plurality of filter discs 32 .

[0029] The cylinder 31 is sleeved on the liner rod 20 , and a straight block 34 engaged with the vertical groove 21 is provided on the inner wall of the cylinder 31 . A plurality of filter discs 32 are vertically spaced apart on the cylinder 31 , and each filter disc 32 forms an annular gap with the inner wall of the shell box 10 .

[0030] The filter disc 32 is preferably a textile filter disc 32. When the urea aqueous solution enters the inner cavity of the shell box 10 and moves downward, it passes through multiple filter discs 32 in sequence, and impurities contained in the urea aqueous solution are effectively filtered out by the multiple filter discs 32. A drain pipe 11 is provided at the bottom of the shell box 10, and the filtered urea aqueous solution can be discharged through the provided drain pipe 11, thereby effectively improving the purity of the filtered urea aqueous solution.

[0031] The adjustment assembly 40 is used to control the plurality of filter plates 32 to form depressions with openings upward or depressions with openings downward.

[0032] When multiple filter discs 32 respectively form depressions with openings facing upward, they are used to filter the urea aqueous solution. On the one hand, this prevents the urea aqueous solution from moving downward without being filtered by the filter discs 32, and on the other hand, the filtered impurities are smoothly retained on the filter discs 32. When multiple filter discs 32 respectively form depressions with openings facing downward, they are used to clean the filter discs 32. By flushing the filter discs 32, impurities can fall downward through the annular gap, making it convenient to clean the impurities.

[0033] The liner rod 20 is rotatably connected to the bottom wall of the shell box 10 , and a belt body 33 connected to the inner wall of the shell box 10 is arranged on the outer side of each filter plate 32 .

[0034] After completing a filtration of the urea aqueous solution, the multiple filter discs 32 respectively form depressions with the openings facing upward, and the cylinder 31 is driven to rotate synchronously by rotating the liner rod 20. The cylinder 31 pulls the filter discs 32 to twist and tighten to squeeze out the residual urea aqueous solution, effectively reducing the loss of the filtered urea aqueous solution.

[0035] Embodiment 2

[0036] A power source 50 is installed at the bottom of the shell box 10 , and the power source 50 is connected to the liner rod 20 through a gear set 51 . The power source 50 is preferably a servo motor to provide power for the rotation of the liner rod 20 .

[0037] An annular tube 12 is provided on the inner wall of the shell box 10, and a plurality of liquid outlet holes are opened on the lower side of the annular tube 12. After cleaning the impurities on the filter plate 32, cleaning water is supplied to the annular tube 12 and discharged through the plurality of liquid outlet holes on the lower side, so that the water flow can flush down the impurities thrown onto the inner wall of the shell box 10.

[0038] The belt body 33 is made of an elastic material, and the elastic material can rotate rubber or other materials, so that the belt body 33 can be deformed and rotate along with the filter 32 .

[0039] Embodiment 3

[0040] The adjustment assembly 40 includes a telescopic source 41 and a top plate 44. The telescopic source 41 is installed on the side wall of the shell box 10. The movable end of the telescopic source 41 is connected to the cross plate 42. The cross plate 42 is provided with a first partition and a second partition vertically spaced apart. The top plate 44 is located between the first partition and the second partition. A connecting rod 43 is provided on the cylinder 31. The connecting rod 43 passes through the first partition and is connected to the top plate 44.

[0041] The telescopic source 41 is preferably an electric cylinder, which drives the horizontal plate 42 to move vertically, thereby driving the horizontal plate 42 located between the first partition plate and the second partition plate to move vertically up and down, so that the cylinder 31 pulls the filter plate 32 to form a depression with an opening upward or a wire with an opening downward.

[0042] A plurality of balls 45 are respectively disposed at the upper and lower ends of the top plate 44. When the top plate 44 rotates with the cylinder 31, the balls 45 contact the first partition plate and the second partition plate, thereby effectively reducing friction.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
