Description

Technical Field

[0001] The utility model relates to the technical field of water treatment resin capture, in particular to a resin capture device. Background Art

[0002] During the brine refining process, the resin will shrink and expand during replacement, causing the resin structure to break down. Some of the broken resin will enter the electrolytic cell along with the refined brine, reducing the electrolytic cell's current efficiency. To prevent broken resin from entering the electrolytic cell, a resin capture device is installed at the resin tower outlet to filter out the broken resin.

[0003] Current resin traps, such as the one with patent number CN102923820A, have a filter element installed inside a cylinder segment, with a drain pipe connected to the middle of the cylinder segment. This allows resin trapped on the filter screen to be discharged without disassembling the filter cartridge, using gravity and the drain pipe. However, during filtration, some resin will accumulate on the surface of the filter element, and the device lacks a cleaning method. Therefore, the resin trap still needs to be disassembled and cleaned after extended periods of time, and its efficiency still needs to be improved. Utility Model Content

[0029] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0030] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0031] Example

[0032] Please refer to Figures 1-4A resin capture device includes an outer shell 1, a water inlet 2 is provided at one end of the outer shell 1, a water outlet 3 is provided at the other end, a cleaning port 4 and a sewage outlet 5 are provided on the ring side of the outer shell 1, a filter component is provided inside the outer shell 1, the water inlet 2, the water outlet 3, the cleaning port 4 and the sewage outlet 5 are all provided with a first valve, the open end of the above-mentioned filter component is provided on the outer shell 1 and is connected with the water outlet 3, and the other end is placed in the outer shell 1 near the water inlet 2, a hand port 7 is provided on the ring side of the outer shell 1, and the hand port 7 is provided with a sealing end cover.

[0033] The principle of the capture device: The capture device is a horizontal device with a main body made of carbon steel and lined with low-calcium-magnesium rubber. The water inlet 2 and the water outlet 3 are located in the middle of both ends of the capture device. When the capture device is working, the first valve of the cleaning port 4 and the first valve of the sewage outlet 5 on the outer shell 1 are closed, and the sealing end cover at the hand port 7 is also in a sealed state. The first valve of the water inlet 2 and the valve at the water outlet 3 are both open. The refined brine coming out of the resin tower enters the inner cavity of the outer shell 1 from the water inlet 2. The refined brine flows from the water outlet 3 through the filter assembly to the brine high-level tank (or secondary brine storage tank). A certain amount of broken resin remains in the inner cavity of the outer shell 1 outside the filter assembly. When a large amount of resin is found inside the collector, that is, it needs to be checked and cleaned immediately, close the first valve of the water inlet 2 and the first valve of the water outlet 3. Open the valve at the water inlet 3, open the first valve of the cleaning port 4, insert the cleaning water pipe into the cleaning port 4, and connect the cleaning water pipe to the cleaning port 4 through a flange connection. Clean water enters the inner cavity of the outer shell 1 through the clean water port and flushes the filter assembly. At the same time, open the sealing end cover at the hand port 7. Personnel can use the hand port 7 to assist in cleaning the filter cylinder and handle the broken resin. After cleaning, open the first valve of the sewage outlet 5 to discharge the waste liquid. After the waste liquid is drained, remove the cleaning water pipe, and close the first valve of the sewage outlet 5, the first valve of the cleaning port 4 and the sealing end cover of the hand port 7 in turn. Then open the first valve of the water inlet 2 and the first valve of the water outlet 3, and the resin capture device resumes normal operation.

[0034] It is worth noting that when personnel clean through the hand port 7, they can also use a small cleaning tool, such as a brush; in addition, the number of hand ports 7 and the number of sealing end caps can be increased or decreased according to the actual resin capture device. The resin capture device is usually large in size. Taking the BZQ series resin catcher as an example, the diameter of the BZQ-250 is DN250 and the length is 837mm. Its disassembly and cleaning requires the cooperation of a crane, which is very labor-intensive and material-intensive. In this design method, the broken resin is intercepted outside the filter component through the special connection method between the filter component and the water inlet 2 and the water outlet 3, and the hand port 7, the cleaning port 4 and the sewage outlet 5 are set on the outer shell 1, so that personnel can clean the broken resin adhering to the outside of the filter component without disassembling the capture device, thereby optimizing the cleaning and maintenance steps, and to a certain extent making the entire cleaning process more convenient, reducing the labor intensity of cleaning the resin catcher.

[0035] As a preferred embodiment, the filter assembly includes a filter cartridge 6 and a filter screen plate 9 provided at the free end of the filter cartridge 6 .

[0036] In the above embodiment, the filter screen material of the filter screen plate 9 is titanium (composite Sharon filter screen). The addition of the filter screen plate 9 can increase the filtering area to a certain extent.

[0037] As a preferred embodiment, the above-mentioned filter assembly also includes a filter layer wrapped around the outside of the above-mentioned filter cartridge 6, a support member is provided between the filter cartridge 6 and the filter layer, and a plurality of fixing members for fixing the filter layer and the support member are spaced apart on the outside of the filter layer.

[0038] In the above embodiment, the support member can be a polytetrafluoroethylene tape wrapped inside the filter cartridge 6. It is worth noting that the polytetrafluoroethylene tape needs to avoid blocking the holes on the filter cartridge 6 as much as possible when wrapping. The support member can increase the strength of the filter assembly under water flow to a certain extent; the setting of the filter layer can improve the quality of resin filtration to a certain extent and prevent broken resin from entering the filter assembly.

[0039] As a preferred embodiment, the filter layer includes multiple layers of first saran mesh 10 .

[0040] In the above embodiment, the saran mesh, also known as the yarn mesh, is a filter mesh woven from specific materials (such as stainless steel wire, copper wire, nickel wire or cellulose, etc.); the multi-layer first saran mesh 10 can increase the filtration area and the number of filtration layers, thereby improving the filtration efficiency and accuracy.

[0041] As a preferred embodiment, the support member includes multiple layers of second saran nets 11 , and the mesh value of the second saran nets 11 is smaller than the mesh value of the first saran net 10 .

[0042] In the above embodiment, the support member uses the second saron net 11, which can make the outer side of the filter component smoother. The multi-layer second saron net 11 can further increase the filtration area and the number of filtration layers while playing a supporting role, thereby improving the filtration efficiency and accuracy; the higher the mesh number of the saron net, the smaller the pore size, the better the filtration effect, and the lower the mesh number of the saron net, the greater its strength. The mesh number of the second saron net 11 as a support member is smaller than the mesh value of the first saron net 10 as a filter layer, which makes good use of the characteristics of the saron net, making it easy for the outer filter layer to intercept impurities, and the support member located on the inner side is not prone to impurity deposition, playing a good supporting role.

[0043] As a preferred embodiment, the support member is a three-layer 12-mesh saron mesh, and the filter layer is a three-layer 64-mesh saron mesh.

[0044] As a preferred embodiment, the fixing member is a titanium hoop 12 .

[0045] In the above embodiment, the titanium hoop 12 is a fastener made of titanium or titanium alloy material. Titanium is a lightweight and high-strength metal that can withstand greater stress and pressure, and the density of titanium is lower than that of many other metals. Therefore, the titanium hoop 12 is both light and strong. In addition, the titanium hoop 12 has good corrosion resistance and is more suitable for working in a long-term flowing water environment.

[0046] As a preferred embodiment, a sight glass 13 is provided on the annular side of the outer shell 1 .

[0047] In the above embodiment, the number of sight glasses 13 can be multiple, preferably the number of sight glasses 13 is 2, preferably the diameter of the sight glasses 13 is 125 mm, and the two sight glasses 13 are symmetrically distributed on both sides of the collector; the sight glasses 13 are arranged in the middle of the outer shell 1, and transparent glass can be selected. This design method allows personnel to easily and accurately judge the working status of the collector, and also to observe whether the resin is rinsed clean when cleaning the filter device.

[0048] As a preferred embodiment, the outer shell 1 includes an outer pipe 8, one end of the outer pipe 8 is provided with a first end cover 14, and the other end is provided with a second end cover 15, the water inlet 2 is provided at the first end cover 14, the water outlet 3 is provided at the second end cover 15, and the filter assembly is connected to the second end cover 15 by bolts.

[0049] In the above embodiment, when the filter assembly needs to be replaced or repaired, the second end cover 15 is first opened, and then the filter assembly connected to the second end cover 15 is disassembled. In addition, the capture device is preferably a horizontal capture device; this design method can facilitate disassembly to a certain extent and facilitate the maintenance work of the collector.

[0050] In summary, the embodiments of the present invention provide a resin capture device that can reduce the labor intensity of cleaning and replacing filters, and can effectively intercept broken resin, improve the quality of brine, and has high application value.
