Description

Technical Field

[0001] The utility model relates to the technical field of adsorption resin screening, in particular to an adsorption resin screening device. Background Art

[0002] Wastewater adsorption resin is a functional polymer material specially used in the field of wastewater treatment. It can effectively adsorb and remove various soluble organic matter, heavy metal ions, pigments and other pollutants from wastewater. This type of resin is usually based on polymer beads, which can be non-polar, polar or with specific functional groups to better match the characteristics of the target pollutants. Screening treatment is required during the production process of adsorption resin.

[0003] During the screening process, particles of the adsorption resin often clog the screening holes. When the screening holes are clogged by large particles of resin, the effective screening area is reduced, which will reduce the efficiency of the screening process and prolong the screening time. In severe cases, it may even lead to an inability to screen. The resin stuck in the screening holes needs to be cleaned away before screening can continue, which makes the device inconvenient to use and affects the screening efficiency. Utility Model Content

[0004] The utility model aims to provide an adsorption resin screening device, which has the advantage of being able to automatically clean the sieve holes to prevent clogging of the sieve holes, and solves the problem that when the current adsorption resin screening device is used, the resin is easy to clog the sieve holes, resulting in a decrease in screening efficiency.

[0005] To achieve the above object, the utility model provides the following technical solution: an adsorption resin screening device, comprising a screening box, a plurality of spring legs are fixed to the bottom of the screening box, a vibration motor is fixed to the top of the screening box, and a feeding shell is connected to the top of the screening box;

[0006] A first sieve plate and a second sieve plate are fixed to the inner wall of the screening box, a plurality of sieve holes are provided on the surface of the first sieve plate and the second sieve plate, a cylinder is provided at the lower right side of the first sieve plate and the second sieve plate, the cylinder is fixedly connected to the right side of the screening box surface, one end of the cylinder passes through the screening box and is fixed with a movable plate, a plurality of compression springs are fixed on the top of the movable plate, a plurality of lifting plates are fixed on the top of the compression springs, a plurality of ejection balls are fixed on the top of the lifting plate, two side discharge ports are provided on the left side of the screening box, and a bottom discharge port is provided at the lower front side of the screening box surface.

[0007] As a preferred adsorption resin screening device of the utility model, the bottoms of the sieve holes on the surfaces of the first sieve plate and the second sieve plate are both provided with expansion parts.

[0008] As a preferred adsorption resin screening device of the utility model, a plurality of slide rails are fixed on both the front and rear sides of the inner wall of the screening box, a plurality of sliders are slidably connected to the surface of the slide rails, and the sliders are fixedly connected to the surface of the movable plate.

[0009] As a preferred adsorption resin screening device of the utility model, a plurality of telescopic rods are fixed on the top of the movable plate, and the tops of the telescopic rods are fixedly connected to the bottom of the jacking plate.

[0010] As a preferred adsorption resin screening device of the utility model, a plurality of bellows are fixed on the top of the movable plate, the top of the bellows is fixedly connected to the bottom of the jacking plate, and the compression spring is located inside the bellows.

[0011] As a preferred adsorption resin screening device of the utility model, the ejection ball is made of polyurethane.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] In the utility model, the adsorbent resin can enter the interior of the screening box. During the continuous vibration of the screening box, the adsorbent resin smaller than the sieve holes will be able to pass through the first sieve plate and fall onto the surface of the second sieve plate, and finally fall into the bottom of the screening box through the sieve holes on the surface of the second sieve plate. Through the multi-stage screening of the first sieve plate and the second sieve plate, the adsorbent resin can be screened more finely. The side discharge port and the bottom discharge port are arranged so that the adsorbent resin that cannot pass through the sieve holes can be taken out from the inside of the side discharge port, and the adsorbent resin that passes through the sieve holes can be taken out from the inside of the bottom discharge port. During the screening process, the cylinder can be started at a fixed time so that the cylinder can push the movable plate toward the left. During this process, the top of the ejection ball contacts the bottom of the first sieve plate and the second sieve plate, so that the compression spring can be in a compressed state. When the movable plate is pushed to the point where the ejection ball is directly under the sieve hole, the ejection ball will no longer be blocked, so that the compression spring can rebound, so that the ejection ball can enter the sieve hole and eject the adsorption resin blocked in the sieve hole. Through this design, the ejection ball can promptly remove the resin particles blocking the sieve hole, maintain good permeability of the two sieve plates, avoid the reduction of screening efficiency due to blockage, reduce the frequency of shutdown for cleaning due to sieve plate blockage, ensure continuous production, and improve production efficiency.

DETAILED DESCRIPTION

[0020] See also Figure 1-5 , an adsorption resin screening device, comprising a screening box 1, a plurality of spring legs 2 are fixed at the bottom of the screening box 1, a vibration motor 3 is fixed at the top of the screening box 1, and a feeding shell 4 is connected to the top of the screening box 1;

[0021] The vibration motor 3 can transmit vibration to the screening box 1 when started, and the spring legs 2 can be compressed and rebounded to improve the vibration effect on the screening box 1. The feeding shell 4 is used to add the adsorption resin to be screened into the screening box 1.

[0022] The first sieve plate 5 and the second sieve plate 6 are fixed to the inner wall of the screening box 1. A plurality of sieve holes 7 are provided on the surfaces of the first sieve plate 5 and the second sieve plate 6. A cylinder 8 is provided at the lower right of the first sieve plate 5 and the second sieve plate 6. The cylinder 8 is fixedly connected to the right side of the surface of the screening box 1. One end of the cylinder 8 passes through the screening box 1 and is fixed with a movable plate 9. A plurality of compression springs 10 are fixed on the top of the movable plate 9. A plurality of jacking plates 11 are fixed on the top of the compression springs 10. A plurality of ejection balls 12 are fixed on the top of the jacking plates 11. The ejection balls 12 are arranged in a semicircular structure. The number, diameter and distribution position of the ejection balls 12 are all adapted to the sieve holes 7. Two side discharge ports 13 are provided on the left side of the screening box 1. A bottom discharge port 14 is provided at the lower front side of the surface of the screening box 1. The sieve holes 7 on the surface of the first sieve plate 5 are larger than the sieve holes 7 on the surface of the second sieve plate 6.

[0023] After being added into the screening box 1, the adsorbent resin will fall onto the surface of the first sieve plate 5. During the continuous vibration of the screening box 1, the adsorbent resin smaller than the sieve hole 7 will be able to pass through the first sieve plate 5 and fall onto the surface of the second sieve plate 6, and finally fall into the bottom of the screening box 1 through the sieve hole 7 on the surface of the second sieve plate 6. Through the multi-stage screening of the first sieve plate 5 and the second sieve plate 6, the adsorbent resin can be screened more finely, and the setting of the side discharge port 13 and the bottom discharge port 14 enables the adsorbent resin that cannot pass through the sieve hole 7 to be taken out from the side discharge port 13, and the adsorbent resin that passes through the sieve hole 7 can be taken out from the bottom discharge port 14. During the screening process, the cylinder 8 can be started at a fixed time so that the cylinder 8 can push the movable plate 9 moves toward the left side. During this process, since the top of the ejection ball 12 contacts the bottom of the first sieve plate 5 and the second sieve plate 6, the compression spring 10 can be in a compressed state. When the movable plate 9 is pushed to the point where the ejection ball 12 is directly below the sieve hole 7, the ejection ball 12 will no longer be blocked, so that the compression spring 10 can rebound, so that the ejection ball 12 can enter the sieve hole 7 and eject the adsorption resin blocked in the sieve hole 7. Through this design, the ejection ball 12 can promptly remove the resin particles blocking the sieve hole 7, maintain good permeability of the two sieve plates, avoid a decrease in screening efficiency due to blockage, reduce the frequency of shutdown for cleaning due to sieve plate blockage, ensure continuous production, and improve production efficiency.

[0024] Furthermore, the bottom of the sieve holes 7 on the surface of the first sieve plate 5 and the second sieve plate 6 are both provided with expansion portions 15;

[0025] With this design, the ejection ball 12 can more easily enter the sieve hole 7 through the cooperation between its top shape and the expansion portion 15, thereby making it easier for the adsorption resin material blocked in the sieve hole 7 to be ejected.

[0026] Furthermore, a plurality of slide rails 18 are fixed on both the front and rear sides of the inner wall of the screening box 1, and a plurality of sliders 19 are slidably connected to the surface of the slide rails 18, and the sliders 19 are fixedly connected to the surface of the movable plate 9;

[0027] When the cylinder 8 pushes the movable plate 9 to move, the movable plate 9 can drive the slider 19 to slide on the surface of the slide rail 18, so that the movable plate 9 can be supported and the movable plate 9 can move more smoothly without misalignment.

[0028] Furthermore, a plurality of telescopic rods 17 are fixed to the top of the movable plate 9, and the top of the telescopic rods 17 is fixedly connected to the bottom of the jacking plate 11;

[0029] The telescopic rod 17 can limit the range of movement of the jacking plate 11 so that the jacking plate 11 can only move up and down, thereby preventing the jacking plate 11 from deviating left and right.

[0030] Furthermore, a plurality of bellows 16 are fixed on the top of the movable plate 9, the top of the bellows 16 is fixedly connected to the bottom of the jacking plate 11, and the compression spring 10 is located inside the bellows 16;

[0031] The bellows 16 can protect the outer surface of the compression spring 10 to prevent the adsorbed resin from entering the interior of the compression spring 10 and affecting the normal compression of the compression spring 10 .

[0032] Further, the ejector ball 12 is made of polyurethane;

[0033] The ejection ball 12 made of polyurethane has excellent wear resistance and good elasticity, and can produce a certain deformation to more easily enter the sieve hole 7, and can also reduce the damage caused by direct impact on the adsorbent resin material.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
