Description

Technical Field

[0001] The utility model belongs to the technical field of resin adsorption tanks, and particularly relates to a resin adsorption tank. Background Art

[0002] In the field of liquid treatment, as an efficient solid-liquid separation device, resin adsorption tanks are widely used in industries such as water treatment, chemical engineering, and medicine. However, there are some deficiencies in existing resin adsorption tanks, especially in the replacement of the resin bed. Traditional resin adsorption tanks usually adopt a fixed resin bed design, which makes the replacement process of the resin bed very cumbersome and time-consuming. Operators need to manually remove the old resin in the tank and then fill in new resin particles. This process not only has a high labor intensity but also low efficiency.

[0003] In addition, due to the fixity of the resin bed, it is difficult to achieve rapid resin replacement, which causes certain limitations in industrial production that requires continuous operation. In some cases, in order to replace the resin bed, it is even necessary to temporarily stop the machine, which not only affects production efficiency but also may lead to an increase in production costs. At the same time, the fixed resin bed design is also not conducive to the hierarchical treatment of resins because the adsorption effects of resin particles of different sizes on different molecules are different, and it is difficult to flexibly adjust the distribution of resin particles in the prior art. Summary of the Invention

[0004] To solve the above-mentioned problems, the utility model discloses a resin adsorption tank, which has a simple structure. Through a lifting structure and a multi-layer structure, it is convenient to replace the resin bed and adjust the height or density of the resin bed to adapt to different operating conditions, improving the use efficiency and flexibility of the equipment.

[0005] To achieve the above object, the specific technical solution of this application is as follows:

[0006] A resin adsorption tank includes a tank body. The tank body is made of stainless steel. There is a sealing cover above the tank body, and the separation and sealing between the sealing cover and the tank body are controlled by a hydraulic lifting system; there is a water inlet pipe on the sealing cover, and a water outlet pipe is arranged below the tank body; a fluid distributor is arranged below the water inlet pipe; there is a resin bed in the tank body, and resin particles of different sizes are filled in the resin bed. The resin bed is located below the fluid distributor, and the resin bed is connected to the sealing cover through a lifting structure. The resin bed is a multi-layer structure, and a quick connection device is used between each layer.

[0007] Based on the above technical features, further, there are lifting lugs above the resin bed, and the lifting lugs are connected to a screw jack to realize up and down movement, which is convenient for replacing the resin bed.

[0008] Based on the above technical features, further, the tank opening is symmetrically provided with a group of flanges, and the hydraulic lifting system includes a hydraulic lifting rod and a control unit. The hydraulic lifting rod is connected to the sealing cover through the through hole of the flange, and the control unit controls the lifting and lowering of the hydraulic lifting rod to achieve a sealed connection between the sealing cover and the tank body.

[0009] Based on the above technical features, preferably, the fluid distributor is a nozzle or a guide plate, and the guide plate has a plurality of guide holes, and the guide holes are evenly distributed to optimize the distribution of the fluid on the resin bed.

[0010] Based on the above technical features, preferably, the sealing cover is provided with a pressure gauge and a safety pressure relief valve.

[0011] Compared with the prior art, the beneficial effects of this application are:

[0012] The present application realizes the rapid up and down movement of the resin bed through the design of the spiral lift and the lifting lug, which greatly simplifies the replacement process of the resin bed, thereby significantly reducing the maintenance time and labor requirements;

[0013] The multi-layer resin bed structure is equipped with a quick connection device, so that each layer of resin can be replaced and maintained independently, reducing the material waste caused by replacing the entire resin bed, effectively reducing maintenance costs, and the number of resin layers can be increased or decreased according to actual working conditions to achieve better adsorption effect;

[0014] The fluid distributor ensures uniform flow of the fluid into the resin bed, avoiding excessive concentration or bypass of the fluid in a local area, and improving the adsorption efficiency;

[0015] The multi-layer structure of the resin bed can be filled with resin particles of different sizes according to the treatment requirements, achieving graded adsorption of pollutants of different molecular sizes, thereby improving the treatment capacity and selectivity.
