[0002] Wastewater treatment is to use physical, chemical and biological methods to treat wastewater, purify wastewater and reduce pollution, so as to achieve wastewater recycling, reuse and full use of water resources. Sand precipitation in wastewater treatment is an important pretreatment link, mainly based on the principle of gravity sedimentation. Since the density of inorganic particles such as sand is greater than that of wastewater, under the condition of slowing down the water flow, the particles gradually sink under the action of gravity, thereby separating from the wastewater. For example, in the horizontal flow sand settling tank, the wastewater flows horizontally at a low speed, so that the sand particles have enough time and conditions to settle at the bottom of the tank.

[0020] The working principle of the above technical scheme is as follows: in use, the user connects the waste water inlet pipe through the water inlet pipe 5, when the waste water enters the inside of the tank body 3, it first impacts the top of the cone body 15, and the water flow hits the cone body 15 and the conical threaded leaf 16, the conical threaded leaf 16 is impacted to make the cone body 15 rotate, and under the rotation of the cone body 15, the water flow spreads to the top of the threaded plate 17, passes through the spiral guide of the threaded plate 17, and is affected by gravity, part of the water flow and impurities pass over the outside of the guide cone plate 18, and follow the guide of the threaded plate 17 and the guide cone plate 18 to enter the inside of the sampling pipe 7, the impurities are intercepted by the filter screen cylinder 8, and the water flow flows back to the inside of the guide ring 2 through the backwater pipe 9, at this time, the water flow flows through the stainless steel pipe 27 under the guide of the guide ring 2 and the limiting of the guide cone ring 26, and the iron sand in the water flow is adsorbed on the outside of the stainless steel pipe 27 due to the magnetic attraction of the magnet rod 25, and then the water flow continues to fall and impact the top of the conical filter screen 22, the conical filter screen 22 exerts a force downward and compresses the return spring 23, the return spring 23 rebounds under the force, so that the conical filter screen 22 shakes up and down under the impact, and due to the conical surface guide of the conical filter screen 22, the impurities slide down the conical filter screen 22 to the outside of the guide cone cylinder 20 under the action of the outer surface and the guide, and the water flow passes through the guide cone cylinder 20 inside the limiting and finally passes through the drain pipe 10, the overall scheme has good filtering effect, high overall efficiency, simple use and long service life.
[0021] In another embodiment, as shown in Figures 1-3 The tank body 3 and the top cover 4 are fixedly connected by the flange ring 6 inside the inserted bolts.
[0022] The connection of the tank body 3 and the top cover 4 facilitates the disassembly and flushing of the inside, and facilitates maintenance.
[0023] In another embodiment, as shown in Figures 1-4 The specification size of the guide cone plate 18 is matched with the specification size of the threaded plate 17, one side of the guide cone plate 18 facing the support 19 is conical, the side of the guide cone plate 18 away from the threaded plate 17 is curved and extends to the inside of the sampling pipe 7, and the outer end of the filter screen cylinder 8 is threadedly and sealingly connected with the outside of the sampling pipe 7.
[0024] The water flow passes through the spiral guide of the threaded plate 17 and is affected by gravity. Part of the water flow and impurities pass over the outside of the guide cone plate 18 and enter the inside of the sampling pipe 7 following the guide of the threaded plate 17 and the guide cone plate 18. The impurities are intercepted by the filter screen cylinder 8, and the water flow returns to the inside of the guide ring 2 through the backwater pipe 9, facilitating the operation personnel to unscrew the filter screen cylinder 8 to view the intercepted dust and sand impurities, and a small amount of waste water is discharged through the sampling pipe 7, thereby facilitating the operation personnel to perform sampling and viewing, facilitating the inspection of the sampling inspection, and the overall use effect is good.

[0026] The scheme conducts magnetic attraction through the stainless steel pipes 27 by the magnetic attraction of the magnet rod 25 to adsorb the iron sand contained in the waste water. When adsorption reaches a certain time, the operation personnel inserts the filter screen disc into the pull-out opening 13 and slides on the top of the support 24, thereby pushing the bottom of the magnet rod 25 and the stainless steel pipe 27. At this time, the pull plate 12 is pulled out to pull out the magnet rod 25 from the inside of the stainless steel pipe 27, so as to break the adsorption of the stainless steel pipe 27 to the outside iron sand. Therefore, the iron sand falls into the filter screen disc, and the operation personnel can pull out the filter screen disc from the inside of the support 24 and the pull-out opening 13. The scheme is convenient for recycling the iron sand, facilitates recycling, increases the convenience of separation, and is convenient to use.
[0027] In another embodiment, as shown in Figures 1-3 The bottom end size of the guide cone ring 26 is smaller than the top end size of the guide cone cylinder 20.

The bottom end of the return spring 23 is fixedly installed at the bottom of the inner cavity of the guide cone cylinder 20. The top end of the return spring 23 is movably contacted with the bottom of the conical filter screen 22. The top of the slide column 21 is internally screwed with a bolt.
[0028] The guide cone ring 26 limits the water flow to the filtering range of the conical filter screen 22 to avoid omission. The top of the conical filter screen 22 is larger than the top of the guide cone cylinder 20. When impacted, it is limited by the top of the guide cone cylinder 20 to cooperate with the return spring 23 to maintain a relatively stable shaking range. The bolt head of the bolt at the top of the slide column 21 is convenient for limiting the conical filter screen 22 and the return spring 23 to avoid falling off.
[0029] In another embodiment, as shown in Figures 1-3 The position of the pull-out opening 13 corresponds to the position of the support 24. The support 24 is located at the periphery of the guide cone ring 26.
[0030] The pull-out opening 13 facilitates the insertion of the filter screen disc or the tray, so as to slide and support the limit position of the support 24 to move, so as to support the bottom of the stainless steel pipe 27, facilitating the operation.
[0031] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
