Description

Technical Field

[0001] The utility model belongs to the technical field of water treatment, and in particular relates to an electrochemical descaling and sterilization integrated device. Background Art

[0002] The principle of electrochemical descaling and sterilization: When circulating cooling water flows through the electrochemical descaling device, a direct current is applied to the electrolytic cell inside the device. Under the action of this electric field, water molecules undergo electrolytic decomposition. At the cathode (negative electrode), water molecules (H2O) receive electrons and are reduced to produce hydrogen (H2) and hydroxide ions (OH⁻). At the anode (positive electrode), some ions in the water (such as chloride ions Cl⁻) may be oxidized, producing hypochlorite or other oxidizing substances with bactericidal properties.

[0003] Electrochemical scale sterilization technology can precipitate scale from circulating water in solid form without adding chemical agents, greatly reducing the scaling tendency of circulating water, ensuring the cleanliness of the heat exchanger surface, ensuring heat exchange efficiency, increasing the concentration multiple of circulating water, reducing sewage discharge, and effectively saving water resources. It is in line with the current national ecological and environmental protection industry policies and dual carbon policies, and has good market prospects.

[0004] In the electrochemical scale sterilization device of the prior art, after being used for a period of time, a layer of scale will adhere to the cathode, resulting in a decrease in the descaling and sterilization capabilities. Therefore, it is necessary to regularly remove the scale on the cathode. For example, the invention patent technology of an electrochemical circulating water automatic descaling system, which was published by the China Patent Office on March 9, 2021, with the publication number CN112461037A, is named. It includes a box, an anode plate, a cathode plate, a central axis, an anode connecting shaft, and a scraper assembly. The central axis is arranged in the middle of the box, the central axis is provided with a cathode plate, the anode connecting shaft is provided with an anode plate, the scraper assembly includes a scraper blade, a scraper frame, a scraper shaft, and a slot; the scraper blade is connected to the scraper slot on the scraper frame through the scraper blade groove, the scraper threaded hole is connected to the scraper shaft, the scraper shaft is arranged on the inner side of the box and passes through the box, the two ends of the scraper shaft are connected to the slot, and the slot is arranged on the outside of the box; a scraper blade is provided on both sides of each cathode plate. The above system can effectively clean the scale on the cathode plate.

[0005] The descaling system of the above structure still has some defects in use:

[0006] 1) A central shaft for installing the cathode plate is set inside the box. The central shaft is a rotating component and both ends of the central shaft need to pass through the box. The sealing requirements at the connection between the central shaft and the box are high, and the processing is difficult.

[0007] 2) During the operation of the system, the cathode plate is descaled. Light scale will flow out of the box with the water flow, increasing the burden on the subsequent scale collector. Heavy scale will be deposited at the bottom of the box. Although it can be discharged regularly through the drain port, the scale will still adhere to the bottom of the box. The bottom of the box needs to be descaled every once in a while.

[0008] 3) Descaling the cathode plate with a scraper will damage the cathode plate. After long-term use, the cathode plate still needs to be replaced. To replace the cathode plate, the center shaft needs to be disassembled, and the center shaft and cathode plate need to be moved out of the box as a whole before the cathode plate can be replaced. The whole process is time-consuming and labor-intensive. Utility Model Content

[0009] The purpose of the utility model is to provide an integrated electrochemical descaling and sterilization device, wherein the cathode plate is installed on the inner side of a flip-up upper end cover. The upper end cover is opened to descale or replace the cathode plate. At the same time, a sintered partition is arranged between the cathode plate and the anode plate to filter and intercept scale in the water flow, thereby reducing the burden on the subsequent scale collector.

[0010] The utility model is realized through the following technical solutions:

[0011] That is, an integrated electrochemical descaling and sterilization device, comprising a box body, a water inlet on one side of the box body, and a water outlet on the other side, characterized in that an upper end cover is provided at the upper end of the box body, one side of the upper end cover is hinged to the box body through a pin shaft, a plurality of cathode plates are provided on the inner side of the upper end cover, a plurality of anode mesh plates are provided inside the box body, the cathode plates and the anode mesh plates are distributed at intervals, a cathode plate seam matching the width and thickness of the cathode plate is provided on the upper end cover, the upper end of the cathode plate is connected to the cathode plate mounting base plate through the cathode plate seam, a handle is provided on the outer end face of the cathode plate mounting base plate, and the cathode plate mounting base plate and the upper end cover are connected by bolts.

[0012] The cathode plate seam of the utility model matches the width and thickness of the cathode plate. After removing the bolts between the cathode plate mounting base plate and the upper end cover, the cathode plate can be pulled out by a handle to scrape off the scale on the cathode plate through the cathode plate seam.

[0013] When the utility model descales the cathode plate, the box cover is first opened and turned to one side of the box body. After descaling is completed, the scale on the box cover is cleaned and then the box cover is restored and locked with the box body.

[0014] When the utility model is used to descale the cathode plate, the sintered screen can be cleaned with high-pressure water flow at the same time.

[0015] The cathode plate and the cathode plate mounting base plate of the present invention are preferably connected by bolts. When the cathode plate needs to be replaced, the cathode plate is completely pulled out through the cathode plate seam and the bolts are unscrewed to conveniently replace the cathode plate.

[0016] In order to ensure the sealing between the upper end cover and the box body, the utility model can set a clamp on the side of the upper end cover, and correspondingly set a handwheel with a locking threaded shaft on the box body. The specific structural principle is the same as the Chinese patent, announcement number CN206858284U, and the name is a box door locking mechanism in a box-type circulating water electrochemical descaling device.

[0017] Furthermore, a plurality of sintered screens are provided on the inner side of the upper end cover of the present invention, and the sintered screens are located between the adjacent cathode plates and anode mesh plates.

[0018] The sintered screen of the utility model is also called sintered screen / sintered metal screen. It is a new type of filter material made of multi-layer metal woven wire mesh through special lamination pressing and vacuum sintering processes, and has high mechanical strength and overall rigid structure.

[0019] The sintered screen can effectively remove scale from the water flow and reduce the burden on subsequent scale collectors.

[0020] Furthermore, each cathode plate mounting base of the present invention is provided with guide holes at both ends, the upper end cover is provided with guide posts matching the guide holes, and one side of the upper end of the guide posts is provided with a limiting bolt.

[0021] Through the guiding effect of the guide column, the cathode plate can be pulled through the cathode plate gap for descaling more stably.

[0022] When the cathode plate needs to be replaced, the limiting bolts on the guide column need to be removed first.

[0023] Furthermore, the handles on each cathode plate mounting plate of the present invention are connected together through a handle connecting rod.

[0024] That is, the multiple cathode plates of the utility model are linked together through the handle connecting rod, and can be pulled out and descaled at the same time.

[0025] In order to ensure the sealing between the cathode plate mounting substrate and the upper end cover, the upper end cover of the utility model is further provided with a countersunk hole matching the cathode plate mounting substrate, the side wall cross-section of the countersunk hole is a stepped structure, and the side cross-section of the cathode plate mounting substrate is a matching stepped structure, and a sealing gasket is also provided between the cathode plate mounting substrate and the upper end cover.

[0026] The utility model has the advantages of reasonable structure, convenient use, and good descaling and sterilization effect. When the utility model is in normal operation, scale in the water flow is filtered and intercepted by the sintered screen, and the descaling effect is good. When the utility model is descaling the cathode plate, the upper end cover can be flipped to remove the cathode plate as a whole from the box body. By pulling out the cathode plate, descaling is carried out through the gap between the cathode plates, without the need for tools such as scrapers, and descaling is quick and convenient.

[0034] The following is a detailed description of the embodiments of the technical solution of the present invention in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention. It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by those skilled in the art to which the present invention belongs. Example 1

[0035] like Figure 1 、 Figure 2 、 Figure 3As shown: a water inlet 1 is provided on the left side of the box body 2, a water outlet 8 is provided on the right side, and a sewage outlet 9 is provided at the bottom. An upper end cover 3 is provided at the upper end of the box body 2. One side of the upper end cover 3 is hinged to the box body through a pin 10. Five cathode plates 5 and eight sintered screens 10 are provided on the inner side of the upper end cover 3. Two sintered screens 10 are provided between two adjacent cathode plates 5. When the upper end cover 3 is snap-fitted and installed on the box body 3, the cathode plate 5 and the anode mesh plate 6 are spaced apart, and a sintered partition 10 is provided between adjacent cathode plates 5 and anode mesh plates 6. The upper end cover 3 is provided with a cathode plate seam that matches the width and thickness of the cathode plate 5. The upper end of the cathode plate 5 passes through the cathode plate seam and is connected to the cathode plate mounting base plate 4 by a cathode plate fixing bolt 10. The cathode plate mounting base plate 4 is provided with a countersunk hole for installing the cathode plate fixing bolt 10. After the cathode plate fixing bolt 10 is installed, both ends of the cathode plate fixing bolt 10 are hidden in the countersunk hole. The upper end cover 3 is provided with a countersunk hole that matches the cathode plate mounting base plate 4. The side wall cross-section of the countersunk hole is a stepped structure, and the side cross-section of the cathode plate mounting base plate 4 is a matching stepped structure. A sealing gasket 15 is also provided between the cathode plate mounting base plate and the upper end cover, and a handle 7 is provided on the outer end face of the cathode plate mounting base plate 4. The cathode plate mounting base plate 4 and the upper end cover 3 are connected by bolts.

[0036] When the present invention is used, like the electrochemical descaling and sterilizing device in the prior art, water enters the box body 2 through the water inlet 1 and is discharged from the water outlet 2 after descaling and sterilization.

[0037] After a period of use, the cathode plate 5 needs to be descaled, such as Figure 4 As shown, open the upper end cover 3 and flip it over (preferably flip it to 180° horizontally with the help of a support platform), unscrew the bolts between the cathode plate mounting base plate 4 and the upper end cover 3, hold the handle 7, pull and pull the cathode plate 5, and use the cathode plate seam on the upper end cover 3 to descale the cathode plate. After pulling and pulling, tighten the cathode plate mounting base plate 4 and the upper end cover 3 with the bolts. The scale filtered by the sintered screen can be flushed with high-pressure water. After the treatment is completed, flip the upper end cover 3 and buckle it with the box body 2 and seal it for reuse.

[0038] When the cathode plate 5 needs to be replaced, the cathode plate 5 can be pulled out and completely separated from the upper end cover 3 , and the cathode plate fixing bolts 10 can be unscrewed to replace the new cathode plate 5 . Example 2

[0039] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 ,like Figure 5 As shown: the handles 7 on the five cathode plate mounting substrates 4 are connected via a handle connecting rod 14, and the rest is the same as in embodiment 1.

[0040] In this embodiment, when descaling the cathode plates 5, the five cathode plates can be operated simultaneously through the handle connecting rod 14, thereby improving efficiency. Example 3

[0042] When descaling the cathode plate 5 , the guide post 15 makes the pulling and drawing of the cathode plate 5 more stable, and under the action of the limiting bolt 16 , the cathode plate 5 will not be pulled out.

[0043] When the cathode plate 5 needs to be replaced, the limiting bolt 16 on the upper end of the guide column 15 needs to be unscrewed first, and the rest is the same as in the first embodiment.

[0044] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and description of the present invention.
