Description

Technical Field

[0001] The utility model relates to the technical field of mechanical basic parts and manufacturing, and particularly relates to an automatic backwashing skid-mounted filter. Background Technique

[0002] In order to avoid excessive impurities in the transported liquid, a filtering structure needs to be installed at the end or center of the pipeline to prevent the pipeline from being blocked due to the accumulation of impurities. The impurity particles in the liquid are usually removed by a filter filled with an adsorption material. As the filtering time increases, more and more impurity particles in the liquid accumulate on the surface of the filter element, which is the core component of the filter. When the pressure difference reaches the set value, the filter element needs to be replaced. In the working conditions with a relatively high pollutant content, the filter element needs to be replaced frequently, resulting in increased maintenance costs and difficulty in extending the service life of the filtering material.

[0003] Now, a new type of automatic backwashing skid-mounted filter is proposed to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide an automatic backwashing skid-mounted filter to solve the problem of inconvenient replacement of the filter element proposed in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an automatic backwashing skid-mounted filter, including a housing and a tank body. The tank body is arranged above the interior of the housing, and notch openings are respectively arranged at the top and bottom of the tank body. Plug plates are inserted and fixed in the notch openings, and bolts are meshed and connected to both sides of the plug plates respectively. A filter membrane is horizontally fixed at the center of the plug plate. Positioning holes are respectively arranged on both sides outside the notch openings. A partition plate is welded at the center of the inner side of the housing, and a funnel is welded at the bottom of the partition plate. A liquid outlet pipe is fixed at the bottom of the funnel, and a first liquid pump is assembled on the liquid outlet pipe. A shunt pipe is welded on the left side of the liquid outlet pipe, and a second liquid pump is assembled on the shunt pipe. A motor is fixed above the outside of the left side of the housing.

[0006] Preferably, the output rotating shaft of the motor is fixedly connected to the tank body, and the tank body can rotate longitudinally inside the housing.

[0007] Preferably, the bolts are embedded in the positioning holes, and the plug plates and the notch openings are arranged in concentric circles.

[0008] Preferably, two groups of partitions are horizontally welded on the inner wall of the tank body. An upper chamber is formed at the top between the partition and the tank body, an intermediate chamber is arranged at the center between the partition and the tank body, and a lower chamber is arranged at the bottom between the partition and the tank body. Sintered particulate matter is filled in the upper chamber, the intermediate chamber and the lower chamber respectively.

[0009] Preferably, the upper chamber, the middle chamber and the lower chamber are in the same vertical plane, and the sintered particulate matter can be adsorbed carbon particles.

[0010] Preferably, a transverse groove is provided at the center of the top of the outer shell, and a hollow gear disk is movably connected to the center of the transverse groove. Linkage gear disks are respectively movably connected to both sides inside the transverse groove. An assembly pipe is movably inserted into the top of the outer shell, and a corrugated pipe is fixed to the top of the assembly pipe. A liquid inlet pipe is fixed to the top of the corrugated pipe. A fixing plate is welded between the liquid inlet pipe and the corrugated pipe, and rotating rods are inserted into holes on both sides of the fixing plate.

[0011] Preferably, the bottom of the rotating rod is fixedly connected to the linkage gear disk, and the linkage gear disks are symmetrically clamped on both sides of the hollow gear disk.

[0012] Preferably, the assembly pipe can vertically lift through the central groove of the hollow gear disk, and the outer wall of the assembly pipe matches the inner groove of the hollow gear disk.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: This automatic backwashing skid-mounted filter not only realizes backwashing of the filter element, realizes stratified filtration of liquid, but also realizes convenient assembly of pipelines;

[0014] By arranging a tank body above the interior of the outer shell, the tank body is located above the partition plate and the funnel. The liquid introduced above the outer shell can enter the tank body through the coarse-pore filter membrane for filtration, and then is led out through the fine-pore filter membrane at the bottom. After the first liquid pump is started and the second liquid pump is closed, it is led out through the funnel and the liquid outlet pipe. If backwashing is required, the tank body is inverted by the motor, with the side of the fine-pore filter membrane facing up and the side of the coarse-pore filter membrane facing down, and the sintered particulate matter is backwashed with the liquid at the top. Closing the first liquid pump and starting the second liquid pump can lead out dirt from the left shunt pipe, extending the service life of the filter element and eliminating the need to replace internal materials multiple times;

[0015] By horizontally welding two groups of partitions on the inner wall of the tank body, the interior of the tank body is divided into an upper chamber, a middle chamber and a lower chamber by the two groups of partitions. While assembling the partitions to separate the chambers, different kinds of sintered particulate matter such as activated carbon, bamboo charcoal, quartz sand particles and other materials are filled in the tank body, and then the upper and lower plates are closed and welded, thus completing the assembly of the filter element main body, realizing multi-level filtration without the need to frequently replace internal materials;

[0016] By arranging a transverse groove at the center of the top of the outer shell, turning the rotating rod at any position above the fixing plate, rotating the linkage gear disk fixedly connected to the rotating rod on the side of the transverse groove. Since the surface of the assembly pipe is covered with threads and can match the meshing groove in the hollow gear disk, and since both sides of the fixing plate are sleeved outside the rotating rod, the assembly pipe can be vertically lifted and the corrugated pipe can be stretched or compressed when the hollow gear disk rotates, enabling the assembly pipe to be inserted into the plug plate to convey liquid without affecting the rotation of the tank body.

[0025] Specifically, as shown in Figure 1 , Figure 2 and Figure 3 , the tank body 9 is located above the partition plate 7 and the funnel 6. The liquid introduced above the outer shell 1 can enter the tank body 9 through the coarse pore filter membrane 21 for filtration, and then be led out through the fine pore filter membrane 21 at the bottom. After the first liquid pump 2 is turned on and the second liquid pump 4 is closed, it is led out through the funnel 6 and the liquid outlet pipe 3. For backwashing, the tank body 9 is inverted by the motor 8, with the side of the fine pore filter membrane 21 facing up and the side of the coarse pore filter membrane 21 facing down, and the sintered particulate matter 24 is rinsed in the reverse direction with the liquid at the top. By closing the first liquid pump 2 and starting the second liquid pump 4, the dirt can be led out from the shunt pipe 5 on the left.

[0026] Embodiment 2: Two groups of partitions 16 are horizontally welded on the inner wall of the tank body 9. An upper chamber 17 is formed at the top between the partition 16 and the tank body 9. An intermediate chamber 18 is arranged at the center between the partition 16 and the tank body 9. A lower chamber 19 is arranged at the bottom between the partition 16 and the tank body 9. The upper chamber 17, the intermediate chamber 18 and the lower chamber 19 are respectively filled with sintered particulate matter 24. The upper chamber 17, the intermediate chamber 18 and the lower chamber 19 are in the same vertical plane. The sintered particulate matter 24 can be adsorption carbon particles.

[0027] Specifically, as shown in Figure 1 and Figure 3 , the interior of the tank body 9 is divided into an upper chamber 17, an intermediate chamber 18 and a lower chamber 19 by two groups of partitions 16. While assembling the partitions 16 to divide the chambers, different kinds of sintered particulate matter 24, such as activated carbon, bamboo charcoal, quartz sand particles and other materials, are filled in the tank body 9, and then the upper and lower plates are closed and welded to complete the assembly of the filter element body.

[0028] Embodiment 3: A transverse groove 10 is arranged at the center of the top of the outer shell 1. A hollow gear disk 26 is movably connected to the center of the interior of the transverse groove 10. Two sides of the interior of the transverse groove 10 are respectively movably connected with linkage gear disks 27. An assembly pipe 15 is movably inserted into the top of the outer shell 1. A corrugated pipe 14 is fixed to the top of the assembly pipe 15. A liquid inlet pipe 11 is fixed to the top of the corrugated pipe 14. A fixing plate 12 is welded between the liquid inlet pipe 11 and the corrugated pipe 14. Rotating rods 13 are inserted into the holes on both sides of the fixing plate 12.

[0029] The bottom of the rotating rod 13 is fixedly connected with the linkage gear disk 27. The linkage gear disks 27 are symmetrically clamped on both sides of the hollow gear disk 26. The assembly pipe 15 can vertically lift through the central groove body of the hollow gear disk 26. The outer wall of the assembly pipe 15 matches the inner groove of the hollow gear disk 26.

[0030] Specifically, as shown in Figure 1 , Figure 2 and Figure 4As shown, turn the rotating rod 13 at any position above the fixed plate 12, and rotate the linkage gear disk 27 fixedly connected to the rotating rod 13 on the side of the transverse groove 10. Since the surface of the assembly pipe 15 is covered with threads, it can match the meshing grooves in the hollow gear disk 26. Since both sides of the fixed plate 12 are sleeved outside the rotating rod 13, when the hollow gear disk 26 rotates, the assembly pipe 15 can be vertically lifted and lowered to stretch or compress the corrugated pipe 14, so that the assembly pipe 15 is inserted into the plug plate 20 to transport liquid.

[0031] Working principle: When the utility model is in use, first, the interior of the tank body 9 is divided into an upper chamber 17, an intermediate chamber 18 and a lower chamber 19 by two groups of partitions 16. While assembling the partitions 16 to separate the chambers, different kinds of sintered particulate matters 24 such as activated carbon, bamboo charcoal, quartz sand particles and other materials are filled in the tank body 9, and then the upper and lower plates are closed and welded to complete the assembly of the filter element main body. After that, turn the rotating rod 13 at any position above the fixed plate 12, and rotate the linkage gear disk 27 fixedly connected to the rotating rod 13 on the side of the transverse groove 10. Since the surface of the assembly pipe 15 is covered with threads, it can match the meshing grooves in the hollow gear disk 26. Since both sides of the fixed plate 12 are sleeved outside the rotating rod 13, when the hollow gear disk 26 rotates, the assembly pipe 15 can be vertically lifted and lowered to stretch or compress the corrugated pipe 14, so that the assembly pipe 15 is inserted into the plug plate 20 to transport liquid. The tank body 9 is located above the partition plate 7 and the funnel 6. The liquid introduced from above the outer shell 1 can enter the tank body 9 through the coarse pore filter membrane 21 for filtration, and then be led out from the fine pore filter membrane 21 at the bottom. After the liquid pump 1 is turned on and the liquid pump 2 is closed, it is led out through the funnel 6 and the liquid outlet pipe 3. If backwashing is required, the tank body 9 is inverted by the motor 8, with the side of the fine pore filter membrane 21 facing up and the side of the coarse pore filter membrane 21 facing down, and the sintered particulate matters 24 are flushed reversely with the liquid at the top. Closing the liquid pump 1 and starting the liquid pump 2 can lead out the dirt from the shunt pipe 5 on the left.
