[0002] Resin capture and retention is an important step in the water system pipeline near the outlet of equipment containing resin, such as ion exchangers. Its main function is to intercept and capture resin particles that may enter the water system to ensure the normal operation of the water system. When the resin quality is poor, the water pressure fluctuates greatly, or the resin cylinder wall is damaged, resin particles may enter the water system and affect other equipment. The resin capture device is like a precision filter, and its filter mesh pore size is much smaller than the resin particles, which can effectively intercept these particles.

[0003] In the prior art, resin is filtered and blocked by a filter screen, but during the filtration process, some resin is often adsorbed on the surface of the resin interceptor filter element, which requires cleaning at regular intervals, otherwise the filtration will be reduced and cannot meet production needs. In the long run, the filtration performance of the filter screen will be affected.

[0004] Therefore, we made improvements on this and proposed a planar ion exchange resin interceptor. Summary of the invention

DETAILED DESCRIPTION

[0029] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples of the specification. The following examples are only used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0030] like Figure 1-Figure 9 As shown, this embodiment proposes a planar ion exchange resin interceptor, including an interception device 1, a plurality of fixed spacers 2 are fixedly installed on the internal upper end surface of the interception device 1, an adjustment mechanism 4 is movably installed below the fixed spacers 2, a filtering structure 3 is arranged between the fixed spacers 2 and the adjustment mechanism 4, both ends of the filtering structure 3 are respectively movably connected in the interception device 1, a guide box 6 is connected below the two ends of the adjustment mechanism 4, and a rotating paddle 5 is installed at the internal bottom end of the interception device 1.

[0031] The interception device 1 includes a frame 11, a channel 14 is opened in the middle of the frame 11, a connecting flange 12 and a rubber edge 13 are connected to the outer side of the frame 11, and installation grooves 15 are symmetrically opened on both sides of the channel 14. Fixed partitions 2, filtering structures 3, adjusting mechanisms 4, rotating paddles 5 and other structures are installed inside the channel 14. When the device is installed on the water system pipeline near the equipment outlet of the resin, the connecting flange 12 and the rubber edge 13 are sealed and connected to the water pipeline, so that the water flows through the fixed partitions 2, filtering structures 3 and adjusting mechanisms 4 inside the channel 14 to intercept the resin, thereby preventing the resin from flowing into the water system.

[0032] The adjusting mechanism 4 includes a plurality of movable spacers 41 and a plurality of fixed frames 42. The movable spacers 41 and the fixed frames 42 are perpendicular to each other. Electric push rods 43 are installed at the four diagonals of the overall structure formed by the movable spacers 41 and the fixed frames 42. The upper end of the movable spacer 41 is fixedly connected with a positioning assembly 44. The positioning assembly 44 is connected to the outside of the filtering structure 3. Both ends of the positioning assembly 44 are connected with connecting pipes 45. The connecting pipes 45 are fixedly connected to the guide box 6. The movable spacer 41 is raised and lowered in the middle of the fixed spacer 2, so that the resin is squeezed out from the gap between the adjacent fixed spacers 2 or the adjacent movable spacers 41 to avoid the resin clogging the gap and reducing the interception effect.

[0033] The filtering structure 3 includes a filter screen 31, and the two ends of the filter screen 31 are respectively wound and connected with a first winding shaft 32 and a second winding shaft 33, and the first winding shaft 32 and the second winding shaft 33 are both mounted in the mounting groove 15, and the first winding shaft 32 and the second winding shaft 33 are both mounted with a motor assembly 34. The filter screen 31 is installed in the middle gap between the fixed partition bar 2 and the adjustment mechanism 4 to increase the interception accuracy of the resin. At the same time, the two sides of the filter screen 31 are connected by the first winding shaft 32 and the second winding shaft 33, which is convenient for adjusting the tightness of the filter screen 31 when the adjustment mechanism 4 is raised and lowered, and adjusting the filtering surface of the filter screen 31 to avoid damage to the filter screen 31 and causing the resin to escape.

[0034] The fixed partition bars 2 are multiple parallel grating plates, and multiple movable partition bars 41 and multiple fixed partition bars 2 are parallel to each other, and the movable partition bars 41 and the fixed partition bars 2 are arranged alternately at intervals. The spacing distance between the movable partition bars 41 and the fixed partition bars 2 is smaller than the diameter of the resin particles. The gap between the fixed partition bars 2 and the movable partition bars 41 separates the resin from the water body, which is convenient for the recycling and reuse of the resin.

[0035] The rotating paddle 5 includes a plurality of paddles, and the filter screen 31 is provided with a rotating paddle 5 with an aperture much smaller than that of the resin particles. During operation, the water flow around the paddles rotates, forming a low-pressure area on the paddles, generating a large number of bubbles, which burst when squeezed by the water flow, and the high-speed jet generated when the bubbles burst flushes the filter structure 3, cleans the resin particles attached to the filter structure 3, and avoids resin adhesion residue.

[0036] There are two guide boxes 6, which are symmetrically installed on both sides of the bottom of the interception device 1. The two guide boxes 6 respectively connect and fix multiple connecting pipes 45 on the same side. The guide box 6 is installed at the bottom end of the interception device 1. When the device is backwashed, the water flow is reversed, and the guide box 6 diverts a part of the water flow and sends the diverted water into the connecting pipe 45, which is discharged from the nozzle 443 in the connecting pipe 45 and the water tank 444 to flush the filter screen 31 clamped on the positioning assembly 44 to avoid resin residue on the filter screen 31.

[0037] The positioning component 44 includes a connecting frame 441, and a pressure strip 442 and a nozzle 443 are connected in the middle of the connecting frame 441. The pressure strip 442 and the nozzle 443 clamp the upper and lower surfaces of the filter structure 3. A water trough 444 is provided in the middle of the nozzle 443. The nozzle 443 is a triangular prism with a sharp angle upward, and the upper ends of the two inclined surfaces of the nozzle 443 are provided with water outlet holes connected to the water trough 444. The upper end of the positioning component 44 is connected to the filter screen 31, so that the adjustment mechanism 4 drives the filter screen 31 to deform up and down. The nozzle 443 installed below the positioning component 4 sprays water to flush the filter screen 31 during backwashing.

[0038] Specifically, when the planar ion exchange resin interceptor is used: the device is installed on the water system pipeline near the outlet of the equipment with resin. When resin particles pass through the outlet pipe of the ion exchanger, the resin particles are intercepted by the fixed spacer 2, the filter structure 3 and the adjustment mechanism 4, and retained on the outlet side of the ion exchanger. When the device is backwashed, the water flow is reversed, the guide box 6 diverts a part of the water flow, and the diverted water is sent to the connecting pipe 45, and the water is discharged from the nozzle 443 in the connecting pipe 45 and the water tank 444, and the filter held on the positioning component 44 is clamped. The net 31 is flushed to avoid resin residue on the filter screen 31. At the same time, the backwash water flow impacts the rotating paddle 5, driving the rotating paddle 5 to rotate. When the blades of the rotating paddle 5 are running, the water flow around the blades rotates, forming a low-pressure area on the blades, generating a large number of bubbles, which burst when squeezed by the water flow. The high-speed jet generated when the bubbles burst flushes the filter structure 3, cleans the resin particles attached to the filter structure 3, avoids resin attachment and residue, and ensures the filtering performance of the filter structure 3.
