Description

Technical Field

[0001] The present application relates to the technical field of basket filters, and in particular to an online cleaning basket filter for high-concentration formaldehyde pipelines. Background Art

[0002] The basket filter body is a small device for removing a small amount of solid particles from the liquid, which can protect the normal operation of the equipment. When the fluid enters the filter cartridge with a filter screen of a certain specification, its impurities are blocked, and the clean filtrate is discharged from the outlet of the filter body. When cleaning is required, just take out the detachable filter cartridge, treat it and reinstall it.

[0003] In daily life, formaldehyde is a toxic and harmful substance. Long-term exposure will have negative effects on human health, such as respiratory irritation, skin damage, etc. Therefore, basket filters are often used to filter high-concentration formaldehyde and reduce the concentration of formaldehyde.

[0004] However, after the filter has been filtering high-concentration formaldehyde for a long time, the filter cartridge inside may become clogged. At this time, the staff needs to stop the operation of the filter to remove and clean the filter cartridge. The equipment can be started normally only after the cleaning is completed, which greatly reduces the work efficiency. At the same time, a small amount of formaldehyde gas will leak to the outside as the filter cartridge is removed, causing physical and mental impact on the staff. For this reason, the present application provides an online cleaning basket filter for pipelines with high-concentration formaldehyde. Utility Model Content

[0005] The purpose of this application is to solve the problem that when the filter cartridge is blocked, the operation of the filter needs to be stopped to remove and clean the filter cartridge. At the same time, a small amount of formaldehyde gas will leak to the outside as the filter cartridge is removed, causing physical and mental impact on the staff. This application provides an online cleaning basket filter for high-concentration formaldehyde pipelines.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0007] An online cleaning basket filter for high-concentration formaldehyde pipelines includes a filter body, a feed inlet is provided on one side of the filter body, a discharge port is provided on one side of the filter body, a fixing ring is fixedly connected to the top of the filter body, a top cover is installed on the top of the filter body, a handle is symmetrically fixedly connected to the top of the top cover, a basket filter is fixedly connected to the inside of the filter body, the top of the basket filter is inclined, a cleaning component is installed at the bottom of the top cover, a limiting component is installed in the fixing ring, and a sewage outlet is provided on one side of the bottom of the filter body.

[0008] By adopting the above technical solution, the external pump body will let the high-concentration formaldehyde enter the interior of the filter body through the feed port, and then filter the formaldehyde through the basket filter, and the filtered formaldehyde will be discharged through the discharge port. During the transmission and filtration process, when the filter holes on the basket filter begin to be blocked, the staff can directly clean the basket filter by operating the cleaning component. There is no need to stop the operation of the equipment, and online cleaning can be performed quickly and efficiently, which greatly improves the overall work efficiency and practicality. Secondly, when the formaldehyde is transported and the operation is ended, clean water can be poured into the filter body to clean the inside of the filter body, and then the drain port can be opened to discharge the sewage. In addition, when the basket filter needs to be replaced later, the top cover and the fixing ring can be separated by pulling the handle upwards to quickly replace the basket filter.

[0009] Furthermore, the cleaning assembly includes a threaded rod that passes through and is rotatably connected to the bottom of the top cover, a knob is fixedly connected to the top of the threaded rod, a cleaning plate is threadedly connected to the knob, and the size of the cleaning plate is consistent with the inner diameter of the basket filter.

[0010] By adopting the above technical solution, since the size of the cleaning plate is consistent with the inner diameter of the basket filter, when the cleaning plate moves, the inner wall of the basket filter can be quickly cleaned, so that online cleaning can be performed quickly and efficiently without stopping the operation of the equipment, greatly improving the overall work efficiency and practicality.

[0011] Furthermore, two guide rods are symmetrically fixedly connected to the bottom of the top cover, and the cleaning plate is slidably connected to the two guide rods.

[0012] By adopting the above technical solution, when the threaded rod starts to rotate, the cleaning plate will move on the threaded rod according to the guidance of the guide rod.

[0014] By adopting the above technical solution, the multiple limit blocks at the bottom of the top cover are aligned with the multiple limit grooves, and then the top cover is pressed downward to push the limit blocks into the limit grooves. At this time, the bottom surface of the limit blocks squeezes the card blocks into the adjustment grooves.

[0015] Furthermore, a spring is fixedly connected inside the adjusting groove, and one end of the spring is fixedly connected to one end of the clamping block.

[0016] By adopting the above technical solution, the card block can be pushed into the interior of the card slot according to the rebound of the spring, so as to fix the limit block.

[0017] Furthermore, one end of the clamping block away from the spring is arc-shaped, and clamping grooves are provided on both sides of the plurality of limit blocks, and the shape and size of the clamping grooves are consistent with the arc-shaped end of the clamping block.

[0018] By adopting the above technical solution, the top cover can be fixed on the top of the filter body through the cooperation of the clamping block and the clamping slot, thereby preventing the top cover from shaking during use.

[0019] Furthermore, the tops of the feed port and the discharge port are fixedly connected with pressure detection gauges, and the pressure detection gauges are electrically connected to an external controller.

[0020] By adopting the above technical solution, during the transmission and filtration process, the transmission pressure value can be detected in real time through the pressure detection gauge. When the filter holes on the basket filter begin to be blocked, the pressure detection gauge will detect that the pressure at the feed port and the discharge port is unstable and the transmission volume is insufficient. At this time, the staff can be reminded through the external controller.

[0021] Furthermore, a sealing ring is fixedly connected to the interior of the top cover.

[0022] By adopting the above technical solution, the sealing between the top cover and the filter body can be maintained by the sealing ring to avoid formaldehyde leakage.

[0024] 1. The present application is provided with a cleaning component. During the transmission and filtration process, the transmission pressure value can be detected in real time through a pressure detection gauge. When the filter holes on the basket filter begin to be clogged, the pressure detection gauge will detect that the pressure at the feed port and the discharge port is unstable and the delivery volume is insufficient. At this time, the staff can be reminded to turn the knob to drive the cleaning plate to move on the threaded rod. The inner wall of the basket filter can be quickly cleaned by the cleaning plate. In this way, online cleaning can be performed quickly and efficiently without stopping the operation of the equipment, which greatly improves the overall work efficiency and practicality.

[0035] When in use, first connect the feed port 2 and the discharge port 3 to the external pump body, and then cover the top of the filter body 1 with the top cover 5. The sealing ring 12 can maintain the sealing between the top cover 5 and the filter body 1 to prevent formaldehyde leakage. When the top cover 5 is covered on the top of the filter body 1, the bottom of the top cover 5 will fit with the top of the fixing ring 4. At this time, the top cover 5 can be stably fixed on the filter body 1 through the cooperation of the limit assembly 9 and the fixing ring 4. At this time, high-concentration formaldehyde can be passed through the feed port 2 into the interior of the filter body 1 through the external pump body, and then the formaldehyde is filtered through the basket filter 7. The filtered formaldehyde is discharged through the discharge port 3. During the transmission and filtration process, the transmission pressure value can be detected in real time by the pressure detection gauge 11. When the filter holes on the basket filter 7 begin to be clogged, the pressure detection gauge 11 will detect that the pressure at the feed port 2 and the discharge port 3 is unstable and the delivery volume is insufficient. At this time, the staff can be reminded through the external controller, and the staff can directly clean the basket filter 7 by operating the cleaning component 8. There is no need to stop the operation of the equipment, and online cleaning can be performed quickly and efficiently, which greatly improves the overall work efficiency and practicality. Secondly, when the formaldehyde is delivered and the operation is ended, clean water can be poured into the filter body 1 to clean the inside of the filter body 1, and then the sewage outlet 10 can be opened to discharge the sewage. In addition, when the basket filter 7 needs to be replaced later, only the handle 6 needs to be pulled upwards to separate the top cover 5 from the fixing ring 4 to quickly replace the basket filter 7.

[0036] Reference Figure 2 and Figure 3 The cleaning assembly 8 includes a threaded rod 81 that is rotatably connected to the bottom of the top cover 5. A knob 82 is fixedly connected to the top of the threaded rod 81, and a cleaning plate 84 is threadedly connected to the knob 82. The size of the cleaning plate 84 is consistent with the inner diameter of the basket filter 7. Two guide rods 83 are symmetrically fixedly connected to the bottom of the top cover 5. The cleaning plate 84 is slidably connected to the two guide rods 83.

[0037] When in use, first turn the knob 82 to drive the threaded rod 81 to rotate. When the threaded rod 81 starts to rotate, the cleaning plate 84 will move on the threaded rod 81 according to the guidance of the guide rod 83. Because the size of the cleaning plate 84 is consistent with the internal diameter of the basket filter 7, when the cleaning plate 84 moves, the inner wall of the basket filter 7 can be quickly cleaned. In this way, there is no need to stop the operation of the equipment, and online cleaning can be performed quickly and efficiently, which greatly improves the overall work efficiency and practicality.

[0038] Reference Figure 1 and Figure 4The limiting assembly 9 includes a plurality of limiting grooves 91 uniformly opened on the top of the fixing ring 4, and adjustment grooves are symmetrically opened on both sides of the limiting grooves 91. Blocks 92 are slidably connected inside the adjusting grooves. A plurality of limiting blocks 94 are uniformly fixedly connected to the bottom of the top cover 5. The shapes and sizes of the plurality of limiting blocks 94 are consistent with the plurality of limiting grooves 91. Springs 93 are fixedly connected inside the adjusting grooves. One end of the spring 93 is fixedly connected to one end of the block 92. The end of the block 92 away from the spring 93 is arc-shaped. Slots 95 are opened on both sides of the plurality of limiting blocks 94. The shape and size of the slots 95 are consistent with the arc-shaped end of the block 92.

[0039] When in use, first take out the top cover 5, align the multiple limit blocks 94 at the bottom of the top cover 5 with the multiple limit grooves 91, then press the top cover 5 downward to push the limit blocks 94 into the limit grooves 91. At this time, the bottom surface of the limit block 94 will squeeze the arc-shaped end of the card block 92 to squeeze the card block 92 into the adjustment groove. When the limit block 94 completely enters the limit groove 91 and the bottom surface of the top cover 5 fits with the top of the fixing ring 4, the card grooves 95 on both sides of the limit block 94 will be in line with the adjustment groove. At this time, the rebound of the spring 93 will push the card block 92 into the card The inside of the groove 95 is used to fix the limit block 94, and through the cooperation of the clamping block 92 and the clamping groove 95, the top cover 5 can be fixed on the top of the filter body 1 to prevent the top cover 5 from shaking during use. Secondly, when the basket filter 7 needs to be replaced, it is only necessary to pull the handle 6 to lift the top cover 5 upward to separate the limit block 94 from the clamping block 92, and the connection between the top cover 5 and the filter body 1 can be released, so as to quickly open the top cover 5 and replace the internal basket filter 7, which effectively improves work efficiency.

[0040] The implementation principle of the online cleaning basket filter for high-concentration formaldehyde pipelines in this embodiment is as follows: when in use, first connect the feed port 2 and the discharge port 3 to the external pump body, then align the multiple limit blocks 94 at the bottom of the top cover 5 with the multiple limit grooves 91, then press the top cover 5 downward to push the limit blocks 94 into the inside of the limit grooves 91, so that it is installed on the filter body 1, and the sealing ring 12 can maintain the sealing between the top cover 5 and the filter body 1 to prevent formaldehyde leakage. When the top cover 5 is covered on the top of the filter body 1, the top cover 5 is When the limit block 94 is completely inserted into the limit groove 91 and the bottom surface of the top cover 5 is in contact with the top of the fixing ring 4, the slots 95 on both sides of the limit block 94 will be in line with the adjusting groove. At this time, the spring 93 will rebound and push the block 92 into the slot 95, so as to fix the limit block 94. Through the cooperation between the block 92 and the slot 95, the top cover 5 can be fixed on the top of the filter body 1 to avoid When the free top cover 5 shakes during use, the high-concentration formaldehyde can be pumped into the interior of the filter body 1 through the feed port 2 through the external pump body, and then the formaldehyde is filtered through the basket filter 7, and the filtered formaldehyde is discharged through the discharge port 3. During the transmission and filtration process, the pressure value of the transmission can be detected in real time by the pressure detection gauge 11. When the filter holes on the basket filter 7 begin to be blocked, the pressure detection gauge 11 will detect that the pressure of the feed port 2 and the discharge port 3 is unstable and the delivery volume is insufficient. At this time, the staff can be reminded by the external controller. The staff can drive the threaded rod 81 to rotate by turning the knob 82. When the threaded rod 81 starts to rotate, the cleaning plate 84 will move on the threaded rod 81 according to the guidance of the guide rod 83. Because the size of the cleaning plate 84 is consistent with the internal diameter of the basket filter 7, when the cleaning plate 84 moves, the inner wall of the basket filter 7 can be quickly cleaned, so that there is no need to stop the operation of the equipment, and online cleaning can be quickly and efficiently performed, which greatly improves the overall work efficiency and practicality.

[0041] Secondly, when the formaldehyde is transported and the operation is ended, clean water can be poured into the filter body 1 to clean the inside of the filter body 1, and then the sewage outlet 10 can be opened to discharge the sewage. In addition, when the basket filter 7 needs to be replaced later, it is only necessary to pull the handle 6 to drive the top cover 5 to lift up, so that the limit block 94 is separated from the card block 92, and the connection between the top cover 5 and the filter body 1 can be released, so as to quickly open the top cover 5 and replace the internal basket filter 7, which effectively improves the work efficiency.
