Description

Technical Field

[0001] This utility model relates to the field of resin trap technology, specifically a corrosion-resistant CPVC vertical resin trap. Background Technology

[0002] A resin trap is a device used to capture resin particles carried out of an ion exchanger by the water. When using resin for online water treatment, if the resin quality is poor, the water pressure fluctuates greatly, or the resin cylinder wall is damaged, the resin will enter the entire water system, affecting the normal operation of other equipment in the system. Therefore, a resin trap is needed. The resin trap is mainly a filter screen with a pore size much smaller than the resin installed on the water system pipeline near the outlet of the ion exchanger or other equipment containing resin. It also has a flushing function. When the resin passes through, it can be intercepted and captured by the filter screen. At the same time, the captured resin is automatically flushed through the differential pressure before and after the filter screen and discharged from the system.

[0003] In the prior art, such as the resin catcher proposed in patent application number "CN202322626074.3", the resin catcher scrapes off the resin adhering to the inner wall of the filter cartridge by moving the threaded cylinder on the threaded rod surface while pushing the cleaning cylinder to move linearly up and down on the filter cartridge surface. The resin then falls naturally into the collection box for collection, thereby improving filtration.

[0004] However, in the aforementioned patent application, the cleaning cylinder is driven by a threaded rod and a threaded cylinder to clean the surface of the filter cartridge. The cleaning method is only a simple scraping and cleaning, and it can only clean the surface of the filter cartridge. It cannot deeply clean the filter holes, resulting in incomplete cleaning. In particular, it is more difficult to completely remove stubborn resin and dirt. Utility Model Content

[0005] The purpose of this invention is to provide a corrosion-resistant CPVC vertical resin catcher to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A corrosion-resistant CPVC vertical resin trap includes a pipe with blind flanges fixedly installed at both ends. A face assembly one and a face assembly two are fixedly connected to the ends of the two blind flanges away from the pipe. A flange gasket is fixedly installed between the face assembly two and one of the blind flanges. Two screen pipes are installed inside the pipe, and auxiliary mechanisms are provided on the outer walls of the two screen pipes.

[0008] The auxiliary mechanism includes an annular movable plate, an annular groove, and an annular connecting plate. The annular movable plate is rotatably connected to one end of the screen tube. The annular groove is located at one end of the screen tube. The annular connecting plate is fixedly connected to the outer wall of the screen tube. Several sliding plates are slidably connected inside the annular groove, and one end of each sliding plate is fixedly connected to the annular movable plate. A wavy groove is provided on the bottom surface of the annular connecting plate. A sliding rod is inserted inside the wavy groove, and a cleaning roller is fixedly connected to the bottom end of the sliding rod.

[0009] Preferably, a plurality of bristles are fixedly connected to the outer wall of the cleaning roller, and an L-shaped connecting plate is fixedly connected to the outer wall of the annular movable plate.

[0010] Preferably, one end of the L-shaped connecting plate is fixedly connected to a connecting frame, and a crossbar is fixedly connected inside the connecting frame.

[0011] Preferably, the outer wall of the slide bar has a through-hole, and the slide bar is movably sleeved on the outside of the crossbar through the through-hole.

[0012] Preferably, springs are fitted on the outside of the crossbar near both ends.

[0013] Preferably, the outer wall of the screen tube is provided with a first mounting groove and a second mounting groove. The first mounting groove is rotatably connected to a gear via a shaft. The top of the second mounting groove is equipped with a motor, and the output end of the motor is connected to the gear.

[0014] Preferably, the outer wall of the annular movable plate is provided with a plurality of toothed grooves, and the plurality of toothed grooves are meshed with gears, and the outer wall of the screen tube is fixedly connected to a shell located outside the gears.

[0015] The beneficial effects of this utility model are:

[0016] In this invention, a motor and gears, in conjunction with various toothed grooves, drive an annular movable plate to rotate inside the screen tube. This allows the cleaning roller to move along the outer wall of the screen tube, and together with the various bristles, it can clean the screen tube. Simultaneously, a sliding rod, in conjunction with a wavy groove on the bottom surface of the annular connecting plate, causes the sliding rod to move back and forth within the wavy groove, driving the cleaning roller to move back and forth and generating vibration. This vibration cleans the screen tube, allowing the bristles to continuously penetrate into the filter holes on the screen tube for cleaning, effectively improving the cleaning effect, removing stubborn dirt and resin, preventing clogging, and ensuring the capture effect is not affected.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] A corrosion-resistant CPVC vertical resin trap, such as Figures 1-6As shown, the device includes a pipe 5, with blind flanges 2 fixedly installed at both ends. Two blind flanges 2 are respectively fixedly connected to a surface assembly 1 and a surface assembly 3 at the ends furthest from the pipe 5. A flange gasket 4 is fixedly installed between the surface assembly 3 and one of the blind flanges 2. Two screen tubes 6 are installed inside the pipe 5. Auxiliary mechanisms are provided on the outer walls of both screen tubes 6. The auxiliary mechanisms include an annular movable plate 8, an annular groove 9, and an annular connecting plate 14. The annular movable plate 8 is rotatably connected inside the screen tube 6 near one end. The annular groove 9 is located at one end of the screen tube 6. The annular connecting plate 14 is fixedly connected to the outer wall of the screen tube 6. Several sliding plates 10 are slidably connected inside the annular groove 9, with one end of each sliding plate 10 fixedly connected to the annular movable plate 8. A wavy groove 7 is provided on the bottom surface of the annular connecting plate 14. A sliding rod 16 is inserted inside the wavy groove 7, and a cleaning roller 22 is fixedly connected to the bottom end of the sliding rod 16.

[0028] When the screen tube 6 rotates, one end of each slide plate 10 moves with the annular movable plate 8, and the other end of each slide plate 10 moves along the annular groove 9, which can limit the rotation position of the annular movable plate 8, so that the annular movable plate 8 remains stable in the screen tube 6. The blind flange 2 serves to connect the surface assembly 1 and the surface assembly 2 3. The external water flow pipe can be connected to the surface assembly 1 and the surface assembly 2 3 to allow the external water flow into the pipe 5 to capture the resin. The flange gasket 4 serves to fill the gap between the surface assembly 2 3 and the blind flange 2, improve the sealing between the surface assembly 2 3 and the blind flange 2, and prevent leakage. Several filter holes are opened through the screen tube 6 for filtering and capturing resin.

[0029] The pipe 5 in this vertical resin trap is made of CPVC, which is a product of further chlorination modification of polyvinyl chloride. It has corrosion resistance, which enables the vertical resin trap to have excellent corrosion resistance.

[0030] The outer wall of the cleaning roller 22 is fixedly connected with several bristles, and the outer wall of the annular movable plate 8 is fixedly connected with an L-shaped connecting plate 20. The cleaning roller 22 moves along the outer wall of the screen tube 6 and, in conjunction with the bristles, can effectively clean the screen tube 6. It can also effectively reach into each filter hole for cleaning under vibration.

[0031] One end of the L-shaped connecting plate 20 is fixedly connected to the connecting frame 15. A crossbar 17 is fixedly connected inside the connecting frame 15. A movable groove 18 is provided through the outer wall of the slide bar 16. The slide bar 16 is movably sleeved on the outside of the crossbar 17 through the movable groove 18. Springs are sleeved on the outside of the crossbar 17 near both ends. The movable groove 18 provides sufficient movement space for the slide bar 16 to reciprocate along the outside of the crossbar 17.

[0032] The outer wall of the screen tube 6 is provided with a first mounting groove 11 and a second mounting groove 19. The first mounting groove 11 is rotatably connected to a gear 12 via a shaft. The top of the second mounting groove 19 is equipped with a motor, and the output end of the motor is connected to the gear 12. The outer wall of the annular movable plate 8 is provided with several toothed grooves 13, and the several toothed grooves 13 are meshed with the gear 12. The outer wall of the screen tube 6 and located outside the gear 12 are fixedly connected to a shell 21.

[0033] In use, the pipe 5 is connected to the water flow that needs to capture resin through the surface assembly 1 and the surface assembly 2 3, so that the water flow enters the pipe 5 and is filtered and captured by the two screen pipes 6. After long-term use, if dirt or resin that is difficult to rinse off adheres to the screen pipes 6, the motor installed in the installation slot 2 19 can drive the gear 12 to rotate in the installation slot 1 11. In conjunction with each tooth groove 13, it can drive the annular movable plate 8 to rotate in the screen pipe 6, thereby driving the L-shaped connecting plate 20 to rotate, and then driving the connecting frame 15 to rotate, so that the cleaning roller 22 moves along the outer wall of the screen pipe 6, and can clean the screen pipe 6 in conjunction with each brush bristle.

[0034] As the cleaning roller 22 moves, the slide bar 16 follows the cleaning roller 22 and moves along the wavy groove 7 opened on the bottom surface of the annular connecting plate 14. Under the shape limitation of the wavy groove 7, the slide bar 16 can reciprocate when moving within the wavy groove 7. That is, the slide bar 16 can reciprocate along the outside of the crossbar 17 through the movable groove 18. The two springs are continuously squeezed and stretched, which plays a role in buffering the movement position of the slide bar 16 and providing support, making the movement of the slide bar 16 more stable. This drives the cleaning roller 22 to reciprocate and generate vibration force, which can vibrate and clean the screen tube 6, allowing the bristles to continuously extend into the filter holes on the screen tube for cleaning, effectively improving the cleaning effect, and brushing out the stubborn dirt and resin, avoiding clogging and affecting the capture effect.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
