Description

Technical fields:

[0001] This utility model relates to the technical field of resin washing devices, and more specifically to a washing tank used for preparing gel macroporous mixed cation exchange resin. Background technology:

[0002] Macroporous strong acid cation exchange resin is a type of resin with a polystyrene backbone and containing sulfonic acid groups (-SO₄). H) functional polymer materials with macroporous structures; gel-type strong acid cation exchange resin is a type of styrene-divinylbenzene copolymer as the matrix, containing strong acid sulfonic acid groups (-SO) H) is an ion exchange material, while gel-macroporous mixed cation exchange resin is a mixed cation exchange resin produced by combining the above two types of exchange resins. The gel-macroporous mixed cation exchange resin requires water washing during its production process. The washing is carried out in a washing tank, which is a circular tank structure with a water inlet pipe at the top. After the resin is put into the washing tank, water is introduced through the inlet pipe, and the resin is washed under the stirring of the stirring structure. After washing, after a period of stillness, the resin and water separate into layers. The water on the upper side is discharged through the drain pipe, while the resin and a small amount of water on the lower side are taken out through the outlet at the bottom of the washing tank. However, during the drainage process, some resin will enter the drain pipe with the water flow. Although the drain pipe has a filter tank structure, cleaning the resin in the filter tank is relatively troublesome. Therefore, a drainage structure that facilitates filtration and cleaning needs to be designed. Utility model content:

[0018] Example: See Figures 1 to 2 As shown, a washing tank for preparing a gel macroporous mixed cation exchange resin includes a cylindrical tank 1. A top cover 2 is fixedly connected to the top of the tank 1. A motor support is fixedly connected to the top cover 2. A vertical stirring motor 14 is fixedly connected to the motor support. The rotating shaft of the stirring motor 14 is fixedly connected to a vertical stirring shaft through a coupling. The lower end of the stirring shaft is inserted into the tank 1. A water inlet pipe 3 is fixedly connected to the upper wall of the tank 1. A drain pipe 4 is inserted and fixedly connected to the lower wall. A drain valve is provided on the drain pipe 4. A connecting pipe 8 is inserted and fixedly connected to the inlet of the drain pipe 4. The end of the connecting pipe 8 is fixedly connected to a longitudinal water outlet pipe 5. The two ends of the water outlet pipe 5 are respectively inserted and fixed to the wall of the tank 1.

[0019] The outlet pipe 5 has an outlet 51 connected to the connecting pipe 8 in the middle. A cylindrical filter screen 7 is inserted into the outlet pipe 5. The two ends of the filter screen 7 abut against the limiting sleeve 6. The limiting sleeve 6 has a regular hexagonal prism hole 62 in the middle. The limiting sleeve 6 is screwed and fixed inside the outlet pipe 5. Several water inlet holes 52 are formed on the outlet pipe 5 at the filter screen 7.

[0020] The front end of the water outlet pipe 5 extends out of the groove 1 and is screwed to a sealing plug 11, and the rear end extends out of the groove 1 and is screwed to a ball valve 9. The rear end of the ball valve 9 is fixedly connected to an air pipe quick connector 10, and an air inlet pipe is inserted into the air pipe quick connector 10.

[0021] The limiting sleeve 6 has a circular positioning boss 61 formed at one end near the drain pipe 4. The end of the filter screen 7 is fitted onto the positioning boss 61 and clamped on the outer wall of the positioning boss 61 and the inner wall of the water outlet pipe 5. The positioning boss 61, in conjunction with the water outlet pipe 5, can fix and limit the filter screen 7 to prevent it from deforming.

[0022] The air inlet pipe on the quick-connect 10 is connected to an air source. The front end of the sealing plug 11 is formed with a "I" shaped handle. When the ball valve is opened, the gas in the air inlet pipe can enter the water outlet pipe 5 and pass through the filter screen 7, thereby discharging through the water inlet hole 52 of the water outlet pipe 5, cleaning the resin particles attached to the water inlet hole 52, and thus unblocking the water inlet hole 52.

[0023] The water outlet pipe 5 is close to the inner wall of the tank 1. The lower part of the stirring shaft is provided with stirring blades. The distance from the outer end of the stirring blades to the center of the stirring shaft is less than the distance from the water outlet pipe 5 to the center of the stirring shaft. When the stirring shaft drives the stirring blades to rotate to wash the resin particles, they will not collide with the water outlet pipe 5.

[0024] The bottom of the trough 1 is provided with a discharge port, and a discharge valve 12 is provided at the discharge port. One side of the discharge valve 12 is hinged to the trough 1, and the other side is formed with a locking plate. The locking plate is formed with a horizontal locking groove, and a stud is inserted into the locking groove. The rear end of the stud is fixed to the trough 1, and the front end is screwed with a pressure cap. The pressure cap presses against the locking plate of the discharge valve 12. A handle is welded and fixed to the pressure cap. By driving the pressure cap, the discharge valve 12 can be opened. After the discharge valve 12 is opened, the resin particles after drainage can be taken out from the discharge port.

[0025] The lower part of the trough cylinder 1 is fixedly connected to three sets of machine feet 15. The machine feet 15 are evenly distributed in a ring around the central axis of the trough cylinder 1, so that the trough cylinder 1 can be erected on the ground.

[0026] A circular observation window 13 is provided on the upper part of the cylinder wall of the tank 1, through which the washing condition in the washing tank can be observed.

[0027] Working principle: This structure is a water washing tank used for preparing gel-macroporous mixed cation exchange resin. The main structure of the water washing tank is as follows: Figure 1 As shown, the technical aspects are reflected in the inlet structure of the drain pipe, such as... Figure 2 As shown, when draining, close the ball valve and open the drain valve on the drain pipe 4. Water enters from the inlet hole 52 of the outlet pipe 5, is filtered by the filter screen 7, and then flows into the drain pipe 4 from the outlet 51 for drainage.

[0028] During the drainage process, a small amount of resin may adhere to individual water inlet holes 52, but this does not affect the drainage of other water inlet holes 52. After drainage is completed, close the drain valve and then open the ball valve 9. The airflow enters the water outlet pipe 5 and exits from the water inlet hole 52, blowing away the resin adhering to the water inlet hole 52, making cleaning convenient.

[0029] The embodiments described above are illustrative of the present invention and are not intended to limit the present invention. Any person skilled in the art can modify the embodiments without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be as set forth in the claims.
