Description
Technical Field
[0001] This invention belongs to the field of resin tower technology, and specifically relates to a device for extending the regeneration cycle of chelating resin towers. Background Technology
[0002] Chelating resin towers play a crucial role in numerous industrial production sectors, such as chemical, electronics, and pharmaceutical industries. Chelating resins, with their unique chelating properties, can efficiently remove specific metal ions from water, ensuring high water quality standards are met during production processes. However, in actual operation, the performance and lifespan of chelating resin towers are significantly affected by the quality of the influent water.
[0003] Influent water often contains impurities such as suspended solids, silt, colloids, organic matter, and various metal ions. Larger particles such as suspended solids and silt may clog the pores of the resin, hindering the contact between metal ions and the active sites of the resin, thus reducing the resin's adsorption efficiency. Colloidal substances easily form a film on the resin surface, hindering ion diffusion and exchange. Organic matter may compete with the resin for adsorption, occupying adsorption sites and reducing the adsorption capacity for target metal ions. Some non-target metal ions may also react with the resin, causing the resin to reach saturation prematurely and shortening the regeneration cycle.
[0004] Therefore, this invention proposes a device for extending the regeneration cycle of a chelating resin tower. This device uses a special pretreatment tank at the front end of the chelating resin tower to perform multi-stage filtration of the influent water using various filter media, effectively removing impurities such as suspended solids, silt, colloids, organic matter and some metal ions from the water, thereby optimizing the influent water quality. Summary of the Invention
[0005] The purpose of this invention is to provide a device for extending the regeneration cycle of chelating resin towers, thereby addressing the problems mentioned in the background art.
[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:
[0007] A device for extending the regeneration cycle of a chelating resin tower includes a tank, with an inlet pipe and an outlet pipe respectively provided at the upper and lower ends of the tank. Multiple baffles are provided in the middle of the tank, with filter media placed on the upper side of the baffles, and cleaning components are provided on the upper side of each of the multiple baffles.
[0008] The cleaning assembly includes a water spray pipe fixed inside the tank, the water spray pipe being located above the partition plate, and a water spraying component being provided at the end of the water spray pipe. The tank body is fixed with a rectangular plate corresponding to the partition plate, the rectangular plate having a rectangular groove, a baffle being slidably disposed within the rectangular groove, the partition plate having a plurality of first water holes, and the baffle having second water holes corresponding one-to-one with the plurality of first water holes. An electrically controlled telescopic rod is installed on the right side of the rectangular plate, the output shaft of the electrically controlled telescopic rod being connected to the baffle plate, and the tank body having a drain pipe corresponding to the partition plate, the drain pipe having an electrically controlled valve.
[0009] The water spray component includes a fixed plate fixed inside the tank. A circular seat is rotatably mounted on the lower side of the fixed plate. A water outlet cavity is provided in the middle of the circular seat. A channel communicating with the upper side of the water outlet cavity is provided in the middle of the fixed plate. The channel is connected to the water spray pipe. A rotating component is provided between the circular seat and the fixed plate.
[0010] Multiple arc-shaped stirring blades are hinged to the lower side of the circular seat, forming a complete circle. A piston block is slidably sealed inside the water outlet cavity. A spring is provided between the lower side of the piston block and the water outlet cavity. A connecting rod extending out of the water outlet cavity is fixed to the lower side of the piston block. A hinge rod corresponding to the multiple arc-shaped stirring blades is hinged to the lower end of the connecting rod. The hinge rod is hinged to the arc-shaped stirring blades.
[0011] The lower side of the water outlet chamber is provided with a drain hole, which is connected to a flexible hose. The arc-shaped stirring blade is hollow inside, and the end of the flexible hose is connected to its interior. Several nozzles are provided on the side wall of the arc-shaped stirring blade.
[0012] The rotating component includes a cavity formed in the side wall of the fixed plate. The cavity is connected to the channel. Several blades are rotatably mounted in the cavity via a rotating shaft. The blades extend into the channel. A gear is connected to the lower end of the rotating shaft. A gear ring that meshes with the gear is mounted on the circular seat.
[0013] Vibration motors are installed at each of the four corners of the rectangular plate.
[0014] The tank has an inspection door on its side wall.
[0015] The tank body of this invention can hold various filter media, such as quartz, fiber balls, and granular activated carbon. Different filter media have excellent removal effects on different impurities. Quartz can intercept larger particulate impurities, fiber balls can effectively remove suspended solids and colloids, and granular activated carbon can adsorb organic matter, residual chlorine, odors, etc., comprehensively optimizing the influent water quality, reducing the adsorption burden on chelating resin, extending the regeneration cycle of the resin tower, and reducing operating costs.
[0016] The baffle is moved by the electric telescopic rod, so that the second water hole on the baffle is misaligned with the first water hole on the partition, and the partition is completely separated. At the same time, the electric valve is opened to connect the drain pipe to the outside, realizing automatic cleaning of the filter media. The cleaning process does not require manual intervention, the operation is simple, and the automation level of the equipment operation is improved.
[0017] The spray pipe is connected to an external high-pressure water pump. Water flows into the channel, driving the blades to rotate, which in turn drives the circular seat to rotate. The water flow pushes the piston block downward, causing the arc-shaped stirring blades to unfold and rotate with the circular seat, stirring and agitating the filter media. Combined with the clean water sprayed from the nozzle, the filter media can be thoroughly and deeply rinsed, effectively removing impurities and improving the regeneration effect and service life of the filter media.

Detailed Implementation
[0028] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0029] like Figure 1-7 As shown, the present invention provides a device for extending the regeneration cycle of a chelating resin tower, comprising a tank 1, with an inlet pipe 11 and an outlet pipe 12 respectively provided at the upper and lower ends of the tank 1, and a plurality of partitions 2 provided in the middle of the tank 1, with filter material placed on the upper side of the partitions 2, and a cleaning component provided on the upper side of each of the partitions 2.
[0030] The cleaning assembly includes a water spray pipe 21 fixed inside the tank 1. The water spray pipe 21 is located on the upper side of the partition 2. A water spraying component is provided at the end of the water spray pipe 21. A rectangular plate 22 corresponding to the partition 2 is fixed to the tank 1. The rectangular plate 22 has a rectangular groove 23. A baffle 24 is slidably provided in the rectangular groove 23. The partition 2 has a plurality of first water holes 201. The baffle 24 has second water holes 241 corresponding to the plurality of first water holes 201. An electrically controlled telescopic rod 25 is installed on the right side of the rectangular plate 22. The output shaft of the electrically controlled telescopic rod 25 is connected to the baffle 24. The tank 1 has a drain pipe 26 corresponding to the partition 2. The drain pipe 26 is equipped with an electrically controlled valve 27.
[0031] The water spraying component includes a fixed plate 3 fixed inside the tank 1. A circular seat 31 is rotatably mounted on the lower side of the fixed plate 3. A water outlet cavity 32 is provided in the middle of the circular seat 31. A channel 33 is provided in the middle of the fixed plate 3, which communicates with the upper side of the water outlet cavity 32. The channel 33 is connected to the water spraying pipe 21. A rotating component is provided between the circular seat 31 and the fixed plate 3.
[0032] Multiple arc-shaped stirring blades 34 are hinged to the lower side of the circular seat 31, forming a complete circle. A piston block 35 is slidably sealed inside the water outlet cavity 32. A spring 36 is provided between the lower side of the piston block 35 and the water outlet cavity 32. A connecting rod 37 extending out of the water outlet cavity 32 is fixed to the lower side of the piston block 35. A hinge rod 38 corresponding to the multiple arc-shaped stirring blades 34 is hinged to the lower end of the connecting rod 37. The hinge rod 38 is hinged to the arc-shaped stirring blades 34.
[0033] The water outlet chamber 32 has a drain hole 321 on the lower side, and the drain hole 321 is connected to a hose 322. The arc-shaped stirring blade 34 is hollow inside, and the end of the hose 322 is connected to its interior. Several nozzles 341 are provided on the side wall of the arc-shaped stirring blade 34.
[0034] The rotating component includes a cavity 4 opened in the side wall of the fixed plate 3. The cavity 4 is connected to the channel 33. Several blades 41 are rotatably installed in the cavity 4 via a rotating shaft. The blades 41 extend into the channel 33. A gear 42 is connected to the lower end of the rotating shaft. A gear ring 43 that meshes with the gear 42 is installed on the circular seat 31.
[0035] Tank 1 is located at the front end of the resin tower. The baffle 2 inside the tank 1 is equipped with filter media to filter the water entering the resin tower, remove suspended solids, silt and other impurities from the water, prevent them from clogging the resin pores, and prolong the regeneration of the chelating resin tower.
[0036] In the initial state, the elastic force of the spring 36 pushes the piston block 35 to the upper end of the water outlet chamber 32. At this time, several arc-shaped stirring blades 34 fit together to form a complete circle, while the electric control valve 27 of the drain pipe 26 is closed. Several first water holes 201 on the partition 2 and several second water holes 241 on the baffle 24 are aligned one by one. When filtering water, the water to be filtered is input through the water inlet pipe 11 at the upper end. The water is filtered and adsorbed by the filter material, and then flows downward through the first water holes 201 and the second water holes 241. After passing through different filter materials on the partition 2 in sequence, the pretreatment of the water is completed. This avoids the poor quality of the inlet water from increasing the adsorption burden of the chelating resin, causing the resin to reach saturation faster, shortening the regeneration cycle, and increasing operating costs.
[0037] The filter media can be quartz. When water flows through the quartz sand layer, impurities larger than the gaps between the sand grains are intercepted, which can effectively intercept larger particles such as suspended solids and silt in the water.
[0038] The filter media can be fiber balls, which have a large specific surface area and high porosity, and can more effectively remove suspended solids and colloids from the water;
[0039] The filter media can be granular activated carbon, which has a rich pore structure and a large specific surface area, and can effectively adsorb organic matter, residual chlorine, odors and other pollutants in water.
[0040] When cleaning the filter media, the electric telescopic rod 25 is activated to move the baffle 24 in the rectangular groove 23, so that the second water holes 241 on the baffle 24 are offset from the first water holes 201 on the partition 2, and the partition 2 is completely isolated. At the same time, the electric valve 27 is controlled to connect the drain pipe 26 to the outside.
[0041] The water spray pipe 21 is connected to an external high-pressure water pump. The high-pressure water pump can pressurize and deliver the cleaning water to the water spray pipe 21. The water flows through the water spray pipe 21 into the channel 33. Since several blades 41 rotatably installed in the cavity 4 extend into the channel 33, the water flow will drive the blades 41 to rotate. That is, the gear 42 can be driven to rotate through the rotating shaft. Since the gear ring 43 on the circular seat 31 meshes with the gear 42, the circular seat 31 can rotate continuously.
[0042] Water flows through channel 33 into outlet chamber 32. The water flow pushes piston block 35 in outlet chamber 32 to move downward against the elastic force of spring 36 until piston block 35 moves to the lower side of drain hole 321. At this time, outlet chamber 32 will be in balance. Water flows through drain hole 321 into hose 322 and finally into the interior of arc-shaped stirring blade 34. It is sprayed out from several nozzles 341 to rinse the filter media.
[0043] When the piston block 35 moves downward, the connecting rod 37 connected to the lower side of the piston block 35 moves downward, and through the hinge rod 38, it pushes several arc-shaped stirring blades 34 to flip to the side, so that the several arc-shaped stirring blades 34 will unfold. The rotation of the circular seat 31 can drive the several arc-shaped stirring blades 34 to rotate. The unfolded arc-shaped stirring blades 34 will stir the filter material and make it turn over. With the sprayed clean water, the filter material can be thoroughly rinsed. Since the partition 2 is completely blocked at this time, the wastewater after rinsing is discharged through the drain pipe 26.
[0044] Vibration motors 221 are installed at the four corners of the rectangular plate 22. The vibration motors 221 can make the rectangular plate 22 vibrate, and the partition 2 located in the tank 1 can vibrate, so that the cleaned filter material is flat.
[0045] The side wall of tank 1 is provided with an inspection door; the inspection door allows for easy replacement of the filter media inside tank 1.
[0046] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
