[0030] In this technical solution, the sand in the sewage can be blocked by the filtering holes 14 on the filtering disc 13. The water will flow through the filtering holes 14 into the lower part inside the sand removal cylinder 1. And the servo motor 6 can drive the rotating shaft 7 and the stirring blades 8 to rotate, stirring the upper part inside the sand removal cylinder 1 and stirring the sewage. Since the specific gravity of the sand is greater than that of the water, the sand is at the edge of the water due to the large centrifugal force, so that the sand passes through the collection box 9 and the mounting frame 15 and enters the collection filter bag 10, cleaning and collecting the sand to prevent the sand from blocking the filtering holes 14 due to excessive amount.

[0031] In some technical solutions, such as Figure 3 and Figure 4 shown, three fixing grooves 17 are provided on the front and rear sides of the mounting frame 15. Three sliding grooves 16 are provided on the front and rear parts of one side of the collection box 9. An L-shaped part 18 is slidably connected inside the sliding groove 16. A spring 19 is arranged inside the sliding groove 16. One end of the spring 19 is fixedly connected with the L-shaped part 18, and the other end of the spring 19 is fixedly connected with the inner wall of the sliding groove 16. The end of the L-shaped part 18 outside the sliding groove 16 is inside the fixing groove 17, and the L-shaped part 18 is adapted to the fixing groove 17.

[0032] During use, pull the L-shaped part 18 to move the L-shaped part 18 and compress the spring 19, so that one end of the L-shaped part 18 is removed from the inside of the fixing groove 17, and the installation of the mounting frame 15 can be released, thus facilitating the installation and disassembly of the collection filter bag 10 and facilitating the removal of the cleaned and collected sand.

[0033] In some technical solutions, such as Figure 1 shown, the top of the sand removal cylinder 1 is fixedly connected with a support frame 11. Electric cylinders 12 are fixedly installed on both sides of the top of the support frame 11. The output ends of the electric cylinders 12 penetrate through the support frame 11 and are fixedly installed with the top of the n-shaped frame 5.

[0034] During use, the electric cylinder 12 can drive the filter cleaning assembly to move in the vertical direction, so as to facilitate moving the filter cleaning assembly into or out of the sand removal cylinder 1.

[0035] In some technical solutions, such as Figure 1 As shown, a drain pipe 3 is connected to the bottom of the sand removal cylinder 1, and a gate valve 4 is arranged on the drain pipe 3.

[0036] During use, it is convenient to open and close the drain pipe 3, so as to drain the water after filtration treatment.

[0040] During use, the anti-slip pads at the bottoms of the legs 2 can increase the stability of the sand removal device.

[0041] In some technical solutions, such as Figure 1 As shown, both the electric cylinder 12 and the servo motor 6 are externally connected to a power source.

[0042] During use, it provides electrical energy for the operation of the electric cylinder 12 and the servo motor 6.

[0043] Working principle: During the use process, the sewage to be de-sanded is injected into the interior of the sand removal cylinder 1. The sand in the sewage can be blocked by the filter holes 14 on the filter disc 13, and the water will flow through the filter holes 14 into the lower part inside the sand removal cylinder 1. And the servo motor 6 can drive the rotating shaft 7 and the stirring blades 8 to rotate, stirring the upper part inside the sand removal cylinder 1 and stirring the sewage. Since the sand is heavier than water, the sand is at the edge of the water due to the greater centrifugal force, so that the sand passes through the collection frame 9 and the installation frame 15 and enters the collection filter bag 10, cleaning and collecting the sand to prevent too much sand from blocking the filter holes 14. When it is necessary to take out the cleaned and collected sand, the electric cylinder 12 can drive the filter cleaning assembly to move in the vertical direction, move the filter cleaning assembly out of the sand removal cylinder 1, pull the L-shaped part 18 to make the L-shaped part 18 move and compress the spring 19, so that one end of the L-shaped part 18 moves out of the inside of the fixed groove 17, and the installation of the installation frame 15 can be released, thus facilitating the installation and disassembly of the collection filter bag 10, and facilitating the taking out of the cleaned and collected sand.
