[0031] Please refer to Figures 4-5As an embodiment of the limiting device: the limiting device comprises a limiting disc 22, a limiting plate 23 is arranged on one side of the sand storage barrel 5, a limiting rod 24 is arranged on the limiting plate 23 in a sliding manner, the limiting disc 22 is provided with a limiting hole 25 matched with the limiting rod 24, the limiting rod 24 is provided with a limiting sheet 26, and a limiting spring 27 is arranged between the limiting sheet 26 and the limiting plate 23. The conical cylinder body 3 is provided with a water-proof cover 28, a connecting rod 29 is arranged between the water-proof cover 28 and the conical cylinder body 3, and a rotation stopping sheet 30 is arranged on the conical cylinder body 3.
[0032] More specifically, the water-proof cover 28 can block the sand and stones deposited at the bottom of the conical cylinder body 3, so that the sand and stones are not easy to float under the impact of the spiral water flow. The rotation stopping sheet 30 can block the spiral flowing water, so that the spiral flowing water stops spirally flowing when flowing to the bottom of the conical cylinder body 3, preventing the sand and stones from causing abrasion to the bottom of the conical cylinder body 3 in the process of spirally flowing at the bottom of the conical cylinder body 3, and improving the practicability of the sand remover main body 1. After the sand and gravel enters the sand storage barrel 5, it is stored in the sand storage cavity 16, preventing sewage from leaking. After the sand and gravel in the sand storage cavity 16 is full, the limiting rod 24 is moved upward, the limiting rod 24 drives the limiting sheet 26 to compress the limiting spring 27, so that the limiting rod 24 is separated from the limiting hole 25, and the hand wheel 17 is rotated, the hand wheel 17 drives the rotating shaft 14 and the rotating plate 15 to rotate, so that the sand discharge pipe 4 is aligned with the next sand storage cavity 16.

Through the rubber pad 21, the connection tightness between the mounting plate 18 and the straight cylinder body 2 is improved.
[0033] In summary, when the whole device is in use or operation: when in use, raw water is introduced into the straight cylinder body 2 through the water inlet pipe 6. After the raw water passes through the water inlet pipe 6 of the cyclone sand removal filter, it first forms a tangential downward flow along the circumference of the straight cylinder body 2. The water flow rotates downward, and when the water flow reaches a certain position of the conical cylinder body 3, it rotates upward along the axis of the cylinder body and enters the filter screen 8, and then is discharged through the outlet pipe 7. At the same time, under the action of fluid inertia centrifugal force and its own gravity, the sand and gravel falls into the sand discharge pipe 4 and the sand storage barrel 5 along the wall surface of the conical cylinder body 3. In order to prevent congestion at the sand discharge pipe 4, the water-proof motor 11 is started to drive the spiral blade 12 to rotate and dredge the sand discharge pipe 4.

After the sand and stones enter the sand storage barrel 5, they are stored in the sand storage cavity 16 to prevent sewage from leaking out. After the sand and stones in the sand storage cavity 16 are full, the limiting rod 24 is moved upward, the limiting rod 24 drives the limiting sheet 26 to compress the limiting spring 27, so that the limiting rod 24 leaves the limiting hole 25, and at the same time, the hand wheel 17 is rotated, the hand wheel 17 drives the rotating shaft 14 and the rotating plate 15 to rotate, thereby aligning the sand discharge pipe 4 with the next sand storage cavity 16. The limiting rod 24 is released, and under the elastic force of the limiting spring 27, the limiting rod 24 extends into the limiting hole 25 of the limiting disc 22, thereby fixing the position of the rotating shaft 14. The sand and stones in the sand storage cavity 16 opposite the sand removal opening 13 are discharged through the sand removal opening 13. When the maintenance outlet pipe 7 and the filter screen 8 are removed, the mounting nut 20 and the mounting bolt 19 can be disassembled. Through the rubber pad 21, the connection tightness between the mounting plate 18 and the straight cylinder 2 is improved.
