Description

Technical Field

[0001] The utility model relates to the technical field of well water filters, in particular to a multi-sand centrifugal net tank self-cleaning filter. Background Art

[0002] At present, conventional filters in the market for well water filters are mainly centrifugal + manual mesh filter combinations, which are popular among market players for their simple structure, simple operation, high filter efficiency and low cost. This filter also has certain disadvantages. It needs to be manually drained at regular intervals, especially when sandy well water causes frequent sand drainage. When there are too many impurities in the mesh core and drainage cannot reduce the pressure difference, the machine needs to be shut down, the mesh core needs to be removed for manual cleaning, and then installed in the equipment and restarted. Especially in the case of a lot of sand, if the sand is not drained in time, it may cause the mesh to be blocked, which will reduce the continuity and efficiency of irrigation. Utility Model Content

[0021] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The present invention will be further described below in conjunction with the embodiments.

[0023] Embodiment: A multi-sand centrifugal screen tank self-cleaning filter, including an inlet pipe 1, on which a check valve 101 is fixedly installed. By setting the check valve 101, the centrifuge 2 is prevented from allowing the centrifugally filtered water to re-enter the inlet pipe 1 when processing well water. The centrifuge 2 is fixedly connected to one side of the inlet pipe 1. Water enters the centrifugal filter body tangentially from the inlet pipe 1, and the rotation generates centrifugal force, which pushes the silt and solid particles with higher density to flow along the pipe wall to form a vortex. Due to the different densities of sand and water, the forces are different under the action of centrifugal force, centripetal buoyancy, and fluid drag, so that the clean water with low density rises and is discharged from the overflow port, and the sand and stones with high density enter the sand settling tank 201, thereby achieving the purpose of sand removal, and the clean water flows downstream along the overflow. The water and sand flow out of the mouth, that is, the water-sand separation is completed. A sand settling tank 201 is fixedly installed at the bottom of the centrifuge 2. By setting the sand settling tank 201, the high-density sand and stones diverted from the well water will be deposited in the sand settling tank 201. A sand discharge solenoid valve is arranged in the sand settling tank 201. The sand discharge solenoid valve controls the sand settling tank 201 to regularly remove sand and stones. A connecting pipe 3 is fixedly connected to the centrifuge 2. The water separated and filtered from the centrifuge 2 enters the horizontal filter 4 through the connecting pipe 3. A fire clamp 301 is fixedly installed at the connection between the centrifuge 2 and the connecting pipe 3. An exhaust valve a302 and a pressure gauge a303 are fixedly installed on the connecting pipe 3. The pressure gauge a303 is used to monitor the air pressure in the centrifuge 2, so as to facilitate the control of the exhaust valve a302 to release the air pressure.

[0024] A horizontal filter 4 is fixedly installed at the end of the connecting pipe 3. A filter screen 403 and a cleaning component are arranged in the horizontal filter 4. The filter screen 403 is used to filter water. A pressure gauge b and an exhaust valve b are fixedly installed on the horizontal filter 4. When impurities continue to increase, the pressure difference before and after the filter screen increases. After the pressure gauge b detects that the pressure in the horizontal filter 4 reaches a certain value, it will control the exhaust valve b to release the air pressure in the horizontal filter 4. A drip irrigation belt 401 is fixedly connected to the bottom of the horizontal filter 4. The water filtered by the filter screen 403 will be discharged through the drip irrigation belt 401. A slow motor 5 is arranged on one side of the horizontal filter 4.

[0025] The cleaning assembly includes a rotating shaft b404 rotatably mounted on the inner side of the horizontal filter 4. The horizontal filter 4 is provided with a forward and reverse motor for driving the rotating shaft b404 to rotate. The rotating shaft b404 drives the telescopic rod 4041 to rotate. The telescopic rod 4041 is fixedly sleeved on the rotating shaft b404. When the support rod 4042 slides along the sliding groove 4011, due to the shape of the track of the sliding groove 4011, the telescopic rod 4041 will continuously extend and retract, which is convenient for controlling the stainless steel brush 405 to continuously slide on the sliding groove 4011. The telescopic end of the telescopic rod 4041 is fixedly connected with the support rod 4042, and the support rod 4042 drives the stainless steel brush 405 to slide continuously on the sliding groove 4011. The stainless steel brush 405 slides along the track of the sliding groove 4011, and the stainless steel brush 405 is rotatably installed on the support rod 4042. The stainless steel brush 405 is used to clean impurities on the filter 403. A sliding groove 4011 is opened on the inner side of the horizontal filter 4, and the end of the support rod 4042 is slidably inserted in the sliding groove 4011. The shape of the sliding groove 4011 helps the stainless steel brush 405 to slide stably, and can always stay on the surface of the filter 403 when cleaning. After cleaning, it returns to a position away from the filter 403, reducing the impact of water entering the horizontal filter 4, thereby helping to reduce damage and extend the service life.

[0026] A slow motor 5 is provided on one side of the horizontal filter 4, and the slow motor 5 is used to control the rotation of the rotating shaft a402. The rotating shaft a402 is rotatably installed in the horizontal filter 4, and the rotating shaft a402 controls the rotation of the filter 403. A turntable 4021 is fixedly installed on the rotating shaft a402, and the turntable 4021 drives the filter 403 to rotate. A plurality of groups of support seats 4022 are fixedly installed on the turntable 4021, and the support seats 4022 are fixedly connected to the filter 403. The support seats 4022 are used to connect the turntable 4021 and the filter 403, and increase the supporting force of the filter 403.

[0027] Working principle: the water inlet pipe 1 is connected to the well water pipe, and the well water enters the centrifuge 2 from the water inlet pipe 1 through the check valve 101. The centrifuge 2 separates the sand and gravel in the water by setting the centrifugal force and sinks it into the sand settling tank 201. The desanded water flows into the horizontal filter 4 through the connecting pipe 3 under the action of centripetal buoyancy, and flows to the drip irrigation belt 401 after being filtered by the filter screen 403 in the horizontal filter 4. When the dirt on the surface of the filter screen 403 increases, the water inlet and outlet pressures increase, and the pressure gauge b monitors the pressure in the horizontal filter 4. When a certain value is reached, the exhaust valve b will be controlled to release the air pressure in the horizontal filter 4, and the forward and reverse motors will be started to control the rotation of the shaft b404. The shaft b404 drives the support rod 4042 to move along the sliding groove 4011 through the telescopic rod 4041. The stainless steel brush 405 on the support rod 4042 cleans the filter 403. The slow motor 5 controls the rotation of the filter 403 through the shaft a402. The filter 403 dumps the garbage on its surface, and the cleaned dirt is discharged through the sewage outlet.
