[0024] A liquid inlet 14 is provided on the top plate of the box body 1, and a liquid outlet pipe 15 connected to the box body 1 is provided on the side plate of the box body 1. A valve 16 is provided on the liquid outlet pipe 15. When the valve 16 is opened, the pickling liquid in the box body 1 can be discharged. When the horizontal plate 2 moves downward to the limit state, the liquid level of the pickling liquid is lower than the lower end of the mesh cylinder 7, and the horizontal plate 2 is lower than the end connected to the liquid outlet pipe 15 and the box body 1.

[0025] The motor 9 is fixed on the left side surface of the outer casing 1 , and the output end thereof penetrates the left side plate of the casing 1 toward the right. The output end of the motor 9 is fixedly connected to the center of the left side surface of the left circular plate 5 .

[0026] The sealing door includes a screw 17 and a sealing plate 18. A plurality of screws 17 are fixed on the outer periphery of the through hole 11 and on the right side surface of the right circular plate 6. The sealing plate 18 is a circular plate with a diameter larger than that of the through hole 11. A plurality of through holes corresponding to the screws 17 are provided on the sealing plate 18. Each screw 17 passes through a corresponding through hole and is limited by a nut 19.

[0027] The box body 1 is provided with a pump body 20, a tube body 1 21 and a tube body 22. The pump body 20 is fixed on the left side surface of the outside of the box body 1. One end of the tube body 1 21 passes through the front side plate of the box body 1 and is connected to the box body 1.

[0028] A viewing window 23 opposite to the net cylinder 7 is provided on the front side plate of the box body 1 , wherein the lower end of the viewing window 23 is lower than the lower end of the net cylinder 7 , and the upper end of the viewing window 23 is higher than the upper end of the net cylinder 7 .

[0029] When in use, in the initial state, the valve 16 is closed, the net cylinder 7 is in a state of lower left and higher right, the hydraulic cylinder 3 drives the cross plate 2 to move downward, and it is observed through the window 23 that when the liquid level of the pickling liquid is lower than the lower end of the net cylinder 7, the hydraulic cylinder 3 stops working, the nut 19 on each screw 17 is unscrewed, the sealing plate 18 is removed, the through hole 11 is opened, and the quartz sand particles to be pickled are fed into the net cylinder 7 through the through hole 11. Since the net cylinder 7 is in a state of lower left and higher right, the feeding is stopped until the quartz sand particles occupy the left half of the net cylinder 7, and the sealing plate 18 blocks the through hole 11 on the right circular plate 6;

[0030] The hydraulic cylinder 3 drives the horizontal plate 2 to move upward, and it is observed through the window 23 until the pickling liquid immerses the left part of the net cylinder 7 (the liquid level of the pickling liquid is located in the middle of the net cylinder 7). The hydraulic cylinder 3 stops working and starts the motor 9. The motor 9 drives the left circular plate 5 to rotate. The left circular plate 5 drives the right circular plate 6 to rotate through the connecting rod 10. The net cylinder 7 rotates with the left circular plate 5 and the right circular plate 6. The rotation of the net cylinder 7 can drive the quartz sand particles in the net cylinder 7 to roll and contact with the pickling liquid. Since the rotation axis of the net cylinder 7 is the central axis of the left circular plate 5, and the net cylinder 7 is initially in a left The left end of the net cylinder 7 moves upward and the right end moves downward. When the left end of the net cylinder 7 moves upward, the quartz sand particles in the left part of the net cylinder 7 move rightward and contact the pickling liquid in the right part of the box body 1. When the net cylinder 7 continues to rotate, the left end of the net cylinder 7 moves from top to bottom and the right end moves from bottom to top. The quartz sand particles in the net cylinder 7 move leftward. Therefore, the quartz sand particles in the net cylinder 7 can repeatedly move left and right during the rotation of the net cylinder 7, so they can contact more with the pickling liquid.

[0031] When the motor 9 drives the mesh drum 7 to rotate, the pump body 20 works, which can drive the pickling liquid in the box body 1 to flow, further improving the contact between the pickling liquid and the quartz sand particles in the mesh drum 7;

[0032] After the pickling is completed, the hydraulic cylinder 3 drives the cross plate 2 to move downward. Through the window 23, when the liquid level of the pickling solution is lower than the lower end of the mesh cylinder 7, the hydraulic cylinder 3 stops working, and the motor 9 makes the mesh cylinder 7 higher on the left and lower on the right, and the sealing door is opened, so that the quartz sand particles in the mesh cylinder 7 can be easily discharged.
