Description

Technical Field

[0001] This utility model relates to the field of adsorption resin cleaning technology, and in particular to an adsorption resin countercurrent cleaning device. Background Technology

[0002] Adsorption resin is a porous, three-dimensional resin adsorbent characterized by adsorption. It is a relatively new type of porous resin developed in the field of polymer science in recent years. It consists of small, spherical, fish-roe-like particles produced by suspension copolymerization of monomers such as styrene and divinylbenzene in the presence of organic solvents such as toluene. It is widely used in wastewater treatment, reagent separation and purification, as a carrier for chemical reaction catalysts, and as packing material for gas chromatography and gel permeation chromatography molecular weight fractionation columns. Its key feature is its ease of regeneration and reusability. When combined with anion and cation exchange resins, it can achieve extremely high levels of separation and purification. In industrial water treatment systems using adsorption resin for desalination, in addition to ion exchange with water, suspended solids, organic matter, and other impurities in the water are also retained by the resin during operation. After use, the retained ions are regenerated using acid and alkali, while suspended solids, organic matter, and other pollutants are generally removed by backwashing with water or air scrubbing before and after regeneration.

[0003] Adsorbent resins often require cleaning before use. Existing cleaning equipment often results in uneven cleaning, failing to thoroughly clean the resin. For example, Chinese patent CN217491859U discloses a counter-current cleaning device for adsorbent resins, including a cleaning tank. A cleaning bag is snapped into the top of the inner cavity of the cleaning tank. A sealing cap is threaded to the middle of the top end face of the cleaning tank. A tilting funnel is hinged to the left side of the top of the cleaning tank, and a drive motor is installed on the right side of the top of the cleaning tank. The left end of the drive motor's drive shaft is connected to the top of a drive gear. The drive motor of this counter-current cleaning device drives the drive gear to rotate through a meshing connection between a driving bevel gear and a driven bevel gear. The drive gear drives a gear turntable to rotate, which in turn rotates the bottom of four twisted ropes, winding them around the neck of the cleaning bag. This locks the neck of the cleaning bag, preventing the adsorbent resin from overflowing during rinsing, thus improving the cleaning efficiency and effect. However, in this patent, due to the design of the cleaning tank, the cleaning effect of the adsorbent resin at the top is lower than that of the resin at the bottom and side walls, resulting in some adsorbent resin not being effectively cleaned and the adsorbent resin being cleaned unevenly within the tank.

[0011] Furthermore, a support rod is provided at the bottom of the machine body, and a chassis is provided at the bottom of the support rod. Beneficial effects

[0012] Compared to existing technologies, this invention offers at least the following advantages: The meshing of the gears and internal gear rings on the rotating shaft causes the spray chamber to rotate during spraying, allowing the cleaning liquid to be sprayed more evenly onto the adsorbent resin, avoiding cleaning dead zones, and enabling the cleaning liquid to more effectively contact the resin particles, thus ensuring thorough cleaning of the adsorbent resin. During the cleaning process, the ultrasonic generators located at the top and bottom generate vibrations that facilitate the removal of stains and impurities from the surface of the adsorbent resin. The ultrasonic generators are located on the inner wall of the jacket, improving the cleaning efficiency of the adsorbent resin, while the sound insulation cotton reduces noise during equipment operation. The synchronous rotation of the stirring blades, side scrapers, and bottom scrapers on the rotating shaft agitates the adsorbent resin, promoting thorough cleaning and improving the cleaning effect. The coordination between the liquid outlet of the storage chamber and the liquid inlet of the spray chamber supplies liquid to the rotating spray chamber. Attached Figure Description

[0021] The side wall of the body 1 is provided with a sandwich layer 3. The outer inner wall of the sandwich layer 3 is provided with sound insulation cotton 4. An ultrasonic generator 5 is provided in the middle of the inner wall of the sandwich layer 3. The top of the sandwich layer 3 is provided with a ring-shaped liquid storage chamber 6. The top of the body 1 is provided with an upper liquid inlet pipe 18 communicating with the liquid storage chamber 6. The top of the body 1 is provided with a spray chamber 19. The top of the inner wall of the body 1 is provided with two ring-shaped partitions 20 spaced vertically. The outer end of the spray chamber 19 is located between the two partitions 20. The inner side wall of the liquid storage chamber 6 is provided with a ring-shaped liquid outlet 22. The outer side wall of the spray chamber 19 is provided with a ring-shaped liquid inlet 23. The liquid outlet 22 and the liquid inlet 23 are connected. Multiple spray nozzles 21 are evenly distributed at the bottom of the spray chamber 19. High-pressure spray nozzles are installed on the spray nozzles 21. The outer wall of the spray chamber 19 is provided with annular grooves 26 at the top and bottom of the liquid inlet 23, and annular sealing rings are provided in the grooves 26, which are in close contact with the side wall of the machine body.

[0022] A motor 7 is located at the center of the top of the machine body 1. The motor shaft of the motor 7 is vertically downward and connected to a rotating shaft 8 located inside the machine body 1. The rotating shaft 8 is equipped with spirally rising stirring blades 24. A gear 9 is fixed to the rotating shaft 8. A circular hollow part is located at the center of the spray chamber 19. An internal gear ring 18 is provided on the side wall of the hollow part. The gear 9 is meshed with the internal gear ring 18.

[0023] Preferably, the top of the rotating shaft 8, located below the spray chamber 19, is provided with one or more L-shaped side scrapers 12, and the outer side wall of the side scraper 12 is provided with a side scraper 13.

[0024] Working Principle: During operation, the adsorbent resin to be cleaned is introduced into the machine body 1 through the input pipe. The upper inlet pipe 18 connects to the external cleaning liquid, supplying cleaning liquid into the storage chamber 6. The cleaning liquid flows through the outlet 22 of the storage chamber 6 into the inlet 23 of the spray chamber 19, and is sprayed out from the high-pressure spray nozzle installed at the bottom spray port 21 of the spray chamber 19, thus cleaning the adsorbent resin. Simultaneously, the lower inlet pipe 29 supplies cleaning liquid. At the same time, the motor 7 is started, and as the rotating shaft 8 rotates, the gear 9 rotates accordingly. The internal gear ring 10 rotates under the drive of the gear 9, thereby rotating the spray chamber 19. The rotation of the spray chamber 19 allows the cleaning liquid to be sprayed more evenly onto the adsorbent resin, avoiding cleaning dead zones and ensuring more effective contact between the cleaning liquid and resin particles, improving cleaning uniformity and ensuring thorough cleaning of the adsorbent resin. During the cleaning process, an ultrasonic generator is activated to generate vibrations that facilitate the removal of stains and impurities from the surface of the adsorbent resin, improving cleaning efficiency. The stirring blades, side scrapers, and bottom scrapers on the rotating shaft rotate synchronously to agitate the adsorption resin, causing the resin particles to constantly change position. This prevents resin particles from accumulating and causing incomplete cleaning in some areas, promoting thorough cleaning of the adsorption resin. The agitation also disturbs the water flow, further enhancing the cleaning effect. After cleaning, the cleaned wastewater is drained through the drain pipe, and then the ball valve is opened to discharge the cleaned adsorption resin.
