[0022] The utility model is further illustrated in the following description and examples, and the mode of the utility model includes but is not limited to the following examples.

[0023] First embodiment:

[0024] As Figures 1-2 The spiral sand-water separator provided by the utility model is shown in the drawings, and it comprises a box body 101, the inside of the box body 101 is a cavity, the periphery is closed, a water inlet 102 and a water outlet 103 are horizontally arranged on the upper end of the side wall of the box body 101 respectively, a sand settling tank 112 is arranged at the lower end of the box body 101, a conveying pipe 108 is arranged at the bottom of the sand settling tank 112, the conveying pipe 108 is in a cylindrical shape, a propeller 109 is arranged in the conveying pipe 108, the end of the propeller 109 is arranged on the central shaft of a motor 110, the other end of the propeller 109 is arranged on the shaft base at the bottom of the sand settling tank 112, after the motor 110 is started, the motor 110 drives the propeller 109 to rotate in the conveying pipe 108, the bottom of the conveying pipe 108 is provided with a discharge port 111, when the propeller 109 rotates, the impurities gathered in the sand settling tank 112 can be pushed into the conveying pipe 108, and along with the further rotation of the propeller 109, the impurities are pushed to the discharge port 111 along the conveying pipe 108, so that the impurities are discharged from the device, a rotating shaft 104 is rotatably arranged in the box body 101, a blade wheel 105 is fixedly arranged on the upper end of the rotating shaft 104 arranged on the upper end of the box body 101, the blade wheel 105 is located on the side of the water inlet 102, a stirring rod 106 is arranged at the lower end of the rotating shaft 104, after sewage enters the box body 101 from the water inlet 102, the large-particle impurities in the sewage are deposited in the sand settling tank 112 under the action of gravity, the water body entering the box body 101 from the water inlet 102 has a certain speed, the water flow impacts on the blade wheel 115 to drive the blade wheel 115 to rotate, at the same time, the blade wheel 115 drives the rotating shaft 104 and the stirring rod 106 arranged at the lower end of the rotating shaft 104 to rotate, after the stirring rod 106 rotates, the deposited material in contact with the stirring rod 106 is disturbed, so that the deposited material is prevented from gathering in the sand settling tank 112.

[0025] By arranging the blade wheel 105 and the stirring rod 106 and other related components, the effect that the deposited material in the sand settling tank 112 is stirred and disturbed is realized, compared with the prior art, the disturbed deposited material can enter the bottom of the sand settling tank 112 and contact the propeller 109, and is taken out from the device by the propeller 109.

[0026] Second embodiment:

[0027] As Figure 2As shown, the inner wall of the box 101 is provided with a spoiler 107, the spoiler 107 is arc-shaped, the upper end of the spoiler 107 is installed on the top of the box 101, and the two sides are installed on the inner wall of the box 101. The spoiler 107 is located on one side of the water inlet 102. When the sewage flow enters the box 101 from the water inlet 102, the water flow flows on the surface of the spoiler 107. In addition, the spoiler 107 is provided with a plurality of baffles perpendicular to the surface thereof, the baffles can block the flow of the water flow, thereby reducing the flow speed of the water flow.

[0028] By arranging the spoiler 107, the flow direction of the water flow can be guided, thereby increasing the flow distance of the water flow. Therefore, the impurities in the water body obtain a longer deposition time. In addition, the baffle has the effect of preventing the flow of the water body and reducing the flow speed of the water body. The speed of the water flow is reduced, and the deposition time is therefore longer.

[0029] Third embodiment:

[0030] As shown in the figure, Figure 2 The spoiler 107 is provided with a filter screen 113 at one end. The filter screen 113 is a stainless steel metal plate. A plurality of through holes are formed on the surface of the metal plate for filtering large-particle impurities in the water. The other end of the filter screen 113 is installed on the inner wall of the box 101. After the sewage enters the box 101 from the water inlet 102, the sewage is first guided by the spoiler 107, and then the sewage is filtered by the filter screen 113, thereby retaining the large-particle impurities in the sewage in front of the filter screen 113. The filtered sewage is discharged from the water outlet 103 after passing through the filter screen 113.

[0031] Fourth embodiment:

[0032] As shown in the figure, Figures 2-3 The upper end of the shaft 104 is fixedly provided with a friction block 115. The friction block 115 is cylindrical. The upper end of the box 101 is provided with a support. A bolt 116 is installed on the support. After the bolt 116 is rotated, the end portion thereof continuously approaches and contacts the friction block 115. When the end portion of the bolt 116 contacts the friction block 115, the friction therebetween increases, that is, a larger torque is required for the rotation of the shaft 104. The impeding effect of the impeller 105 installed on the shaft 104 on the water flow is enhanced.

[0033] Fifth embodiment:

[0034] As shown in the figure, Figure 3 The upper end of the shaft 104 is provided with a handle 114. The handle 114 is perpendicular to the shaft 104. When the shaft 104 rotates, the handle 114 rotates together to facilitate the judgment of the rotation speed of the shaft 104 by the staff. When the flow speed of the sewage is small and cannot drive the impeller 105 and the shaft 104 to rotate, the shaft 104 can be manually rotated through the handle 114, thereby driving the stirring rod 106 at the lower end of the shaft 104 to rotate.

[0035] Sixth embodiment:

[0036] As Figure 2 shown, the lower end of the delivery pipe 108 is also provided with a backflow port 117, and a filter sheet is installed at the backflow port 117. The filter sheet is a metal sheet consistent with the curvature of the delivery pipe 108, and has through holes on the surface for draining water. When the sand and stones are delivered from the sand trap 112 to the delivery pipe 108 by the propeller 109, the water carried by the sand and stones is drained out of the device at the filter sheet.

[0037] Working principle: the water enters the box 101 from the water inlet 102 at a certain speed, and the water flow impacts on the impeller 115 to drive the impeller 115 to rotate. At the same time, the impeller 115 drives the rotating shaft 104 and the stirring rod 106 installed at the lower end of the rotating shaft 104 to rotate. After the stirring rod 106 rotates, the deposited substances in contact with the stirring rod 106 are disturbed to prevent the deposited substances from gathering in the sand trap 112.

[0038] The above embodiment is only one of the preferred embodiments of the present application, and should not be used to limit the protection scope of the present application. Any modification or polishing without substantial meaning made on the basis of the main design idea and spirit of the present application, and the technical problems solved by the modification or polishing, should be included in the protection scope of the present application.
