Description

Technical Field

[0001] The utility model relates to the technical field of adsorption resin cleaning devices for pure water treatment systems, in particular to an adsorption resin countercurrent cleaning device. Background Art

[0002] Adsorption resin is a resin adsorbent with a porous three-dimensional structure characterized by adsorption. It is a newly developed porous resin in the field of polymers in recent years. It is a small fish roe-like sphere made 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, pharmaceutical separation and purification, as a carrier of chemical reaction catalysts, gas chromatography analysis and gel permeation chromatography molecular weight classification column filler. Its characteristics are easy to regenerate and can be used repeatedly. If combined with anion and cation exchange resins, it can achieve a very high level of separation and purification. In the industrial water treatment system using adsorption resin for desalination, when the adsorption resin is in operation, in addition to ion exchange with water, impurities such as suspended matter and organic matter in the water will also be retained by the resin. After use, the retained ions are regenerated with acid and alkali. Suspended matter, organic matter and other pollutants are generally removed by backwashing with water or air scrubbing before and after regeneration.

[0003] After searching, a kind of adsorption resin countercurrent cleaning device (201921068610.X) includes a support base, the interior of the support base is fixedly connected to a resin cleaning tank, the bottom of the support base is fixedly connected to a support leg, the bottom of the support leg is fixedly connected to a support plate, and the interior of the support plate is provided with fixing screws. When using the adsorption resin countercurrent cleaning device, the height of the liquid level in the resin cleaning tank is observed through a transparent plate, and then the hard drainage pipe is placed at a suitable height. Finally, the hard drainage pipe is fixed in position by turning the knob, and then the water pump is started to extract the waste liquid from the resin cleaning tank, achieving the purpose of convenient adjustment and increasing work efficiency. The support plate is fixedly connected to the ground by fixing screws to fix the position of the device. When running the device, the shaking of the resin cleaning tank can be reduced, and the rotation of the stirring blade can be made more stable, achieving the purpose of reducing shaking.

[0024] Embodiment 1

The lower surface of the resin cleaning tank 1 is fixedly connected with a liquid outlet pipe 7, and the lower surface of the liquid outlet pipe 7 is fixedly connected with a baffle plate 8, and the lower surface of the baffle plate 8 is fixedly connected with a second motor 42. A liquid outlet 9 is opened on the lower surface of the baffle plate 8. By adding a pipeline to the liquid outlet 9, the resin flows out from the liquid outlet 9, and at the same time, it is ensured that the bottom of the liquid outlet pipe 7 can be fixed with the second motor 42. The power supply frequency of the first motor 2 is lower than that of the second motor 42. The power supply frequency of the first motor 2 is lower than that of the second motor 42. When the first motor 2 and the second motor 42 are started at the same time, the output shaft of the second motor 42 rotates faster than the output shaft of the first motor 2. At the same time, according to the fan-shaped cross-sectional shape of the scraper 44, the cylindrical liquid outlet pipe 7 can be effectively scratched.

[0026] In this embodiment, through the cleaning mechanism 4, when the first motor 2 and the second motor 42 rotate in the same direction at the same time, the output shaft of the second motor 42 will drive the sleeve rod 43 and the rotating rod 41 to rotate, and the sleeve rod 43 will drive the scraper 44 to rotate, thereby scratching the inner wall of the liquid outlet pipe 7 to prevent the resin from adhering to the inner wall.

[0027] Embodiment 2

[0028] See also Figure 1-4On the basis of the first embodiment, the utility model provides a technical solution: preferably, a linkage mechanism 10 is arranged in the first slide groove 3, and the linkage mechanism 10 comprises: an arcuate slide groove 101, the arcuate slide groove 101 is arranged on the inner arc surface of the first slide groove 3, and the arcuate slide groove 101 is arranged on the inner arc surface of the first slide groove 3. When the output shaft of the second motor 42 drives the rotating rod 41 to rotate, the guide rod 102 slides in the arcuate slide groove 101, so that the guide rod 102 drives the rotating rod 41 to move downward, and at the same time drives the scraper 44 downward to scrape the inner wall of the liquid outlet pipe 7, thereby comprehensively preventing the resin from sticking to the inner wall of the liquid outlet 7. The guide rod 102 is slidably connected to the inner wall of the arcuate slide groove 101, and the shape of the guide rod 102 is cylindrical. At the same time, the end of the guide rod 102 close to the arcuate slide groove 101 is hemispherical, and the left surface of the guide rod 102 A slider 103 is fixedly connected, and a second slide groove 11 is provided on the outer arc surface of the rotating rod 41. Through the second slide groove 11 provided on the outer arc surface of the rotating rod 41, the slider 103 can drive the guide rod 102 to move vertically in the second slide groove 11. The inner wall of the second slide groove 11 is slidably connected with the slider 103. The upper ends of the inner walls of the slider 103 and the second slide groove 11 are respectively fixedly connected to the two ends of the second spring 12. A third slide groove 13 is provided on the inner arc surface of the first slide groove 3. The radius of the third slide groove 13 is larger than that of the first slide groove 3. At the same time, the third slide groove 13 is connected with the arc slide groove 101. After the guide rod 102 slides out of the arc slide groove 101, it will slide in the third slide groove 13. When the second motor 42 rotates in the opposite direction, the guide rod 102 will be pulled back into the arc slide groove 101 by the pulling force of the second spring 12, thereby moving the rotating rod 41 upward.

[0029] In this embodiment, the linkage mechanism 10 is set up to effectively ensure that when the second motor 42 rotates in the opposite direction, the rotating rod 41 will move upward, and drive the scraper 44 and the sleeve rod 43 upward at the same time, so that the sleeve rod 43, the scraper 44 and the rotating rod 41 can achieve a vertical reciprocating motion state.

[0030] Working principle: when the resin cleaning tank 1 cleans the resin, the first motor 2 and the second motor 42 are started, the output shaft of the first motor 2 rotates counterclockwise, and the output shaft of the second motor 42 drives the rotating rod 41 to rotate counterclockwise. When the rotating rod 41 rotates counterclockwise, the guide rod 102 slides in the arc-shaped slide groove 101, and drives the rotating rod 41 to move downward while rotating. The rotating rod 41 drives the sleeve rod 43 and the scraper 44 to move downward, and scrapes the inner wall of the liquid outlet pipe 7. When the scraper 44 moves to the upper surface of the baffle 8, the sleeve rod 43 compresses the first spring 6, so that the scraper 44 has a certain buffering effect. After the guide rod 102 slides out of the arc-shaped slide groove 101, it rotates in the third slide groove 13. The guide rod 102 has a continuous upward pulling force under the influence of the second spring 12. When the second motor 42 rotates in the opposite direction, the rotating rod 41 will drive the guide rod 102 to be re-engaged in the arc-shaped slide groove 101, drive the rotating rod 41 to move upward, and return the scraper 44 and the sleeve rod 43 to their original positions.
