[0002] Currently, in the process of treating wastewater by electrolysis, the surfaces of the anode and cathode are easily adsorbed by dirt, which will affect the electrolysis effect of the electrode plates over a long period of time. We found that application number CN201610469102.7 is a scraper descaling device for electromagnetic chemical water treatment. This invention has a simple structure and improves the fixing method of the negative electrode plate of the automatic bonding scraper descaling device. It solves the problems of scraper shaking, swaying, warping and incomplete tight bonding caused by unreasonable structure of the scraper in electrochemical water treatment device. It comprehensively and effectively improves the descaling effect and has low labor cost.

[0003] Similar to the scraper descaling device in the electromagnetic chemical water treatment described above: Although the fixing method of the negative electrode plate of the automatic fitting scraper descaling device has been improved, solving the problem of scraper wobbling caused by unreasonable structure in the electrochemical water treatment device, the scraper for removing impurities is set on the negative electrode in the existing technology, resulting in the negative electrode being too heavy and increasing costs. At the same time, tools are required for the installation or disassembly of the scraper during routine maintenance and replacement.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a negative electrode scraper roller that is easy to install, so as to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this utility model is to provide a negative electrode scraper roller that is easy to install, in order to solve the problems mentioned in the background art of the above-mentioned electromagnetic chemical water treatment scraper scraping device, in which the scraper for removing impurities is set on the negative electrode, resulting in the negative electrode being too heavy and increasing costs. At the same time, the scraper requires tools to be used for installation or disassembly during routine maintenance and replacement.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a negative electrode scraping roller that is easy to install, comprising a water tank, a cathode plate and a scraping oil cylinder. The cathode plate is connected to the middle of the water tank by fixing bolts at equal intervals. Anode plates are distributed crosswise on one side of the cathode plate. Fixing seats are connected to the middle of the outer walls on both sides of the water tank by bolts. The scraping oil cylinder is located on the top of the fixing seat.

[0007] Furthermore, the top of the scraping cylinder is connected to a fixed plate, and a connecting rod is bolted to the bottom of the fixed plate on the side near the water tank.

A first spring is connected to one side of the limiting groove, and a fixing plate is connected to the side of the first spring away from the edge of the limiting groove. The end of the fixing plate away from the first spring is embedded in the through groove.

[0009] Furthermore, a connecting rod is connected to the top of the fixed insert plate near the first spring. The end of the connecting rod away from the fixed insert plate passes through the limiting groove and is connected to a pull block. Through holes are provided at all four ends of the edge of the scraper. Limiting rods are fixedly connected to the inner edge of the water tank. The middle part of the limiting rod passes through the through hole for fixation.

[0010] Furthermore, a scraping mechanism is equidistantly arranged on the inner side of the scraping frame. The scraping mechanism is staggered with the cathode plate. The scraping mechanism includes a fixing bar, a scraping plate, a rotating hinge, and a second spring. The top two sides of the fixing bar are connected to scraping plates through rotating hinges. A second spring is arranged on the bottom outer wall of the scraping plate near the fixing bar. The end of the second spring away from the scraping plate is connected to the fixing bar. The scraping plate abuts against the cathode plate.

A drain outlet is provided at the center of the bottom of the water tank, a water inlet is provided on one side of the outer wall of the water tank, and a water outlet is provided on the side of the water tank away from the water inlet.

[0012] Compared with the prior art, the beneficial effects of this utility model are: a convenient negative electrode scraper roller, which uses a through groove and a fixing plate for fixation. When installing the scraper frame, pulling the pull block drives the connecting rod, thereby moving the fixing plate to a certain position, and the bottom ends of the two sets of connecting rods are embedded in the limiting groove.

The end of the fixing plate furthest from the first spring is embedded in the through groove, while the end of the fixing plate closest to the first spring... A connecting rod is connected to the top of one side of the spring. The connecting rod can pull the fixed insert plate. The end of the connecting rod away from the fixed insert plate passes through the limiting groove and is connected to a pull block. When installing the scraper, the pull block is pulled.

The first spring is compressed and contracts, embedding the bottom ends of the two sets of connecting rods into the limiting groove. The through groove and the fixed insert plate are on the same straight line. After releasing the pull block, the rebound of the first spring causes the fixed insert plate to be embedded in the through groove, thus realizing the connection between the connecting rod and the scraper. The scraper can be installed and disassembled without tools. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 This utility model provides a technical solution: a conveniently installed negative electrode scraping roller, including a water tank 1, a cathode plate 2, and a scraping oil cylinder 5. The cathode plate 2 is equidistantly connected to the middle of the water tank 1 by fixing bolts. Anode plates 3 are distributed crosswise on one side of the cathode plate 2. When the cathode plate 2 and anode plate 3 are energized, a special electric field is formed between the cathode plate 2 and anode plate 3. Positive ions move rapidly towards the negative electrode plate. At the same time, an alkaline environment is formed around the negative electrode plate, generating a large number of negative ions such as carbonate ions that accumulate and form scale. These negative ions combine with positive ions to quickly generate scale and deposit on the cathode plate 2, thereby treating the circulating water system. The middle of the outer walls on both sides of the water tank 1 is connected to a fixing seat 4 by bolts. The fixing seat 4 serves to fix the tank. The scraping oil cylinder 5 is located on the top of the fixing seat 4.

[0021] The top of the scraping cylinder 5 is connected to the fixed plate 6. The scraping cylinder 5 can drive the fixed plate 6 to move up and down horizontally. The bottom of the fixed plate 6 near the water tank 1 is connected to a connecting rod 7 by bolts. The connecting rod 7 serves as a connection. The bottom of the connecting rod 7 is provided with a through groove 71. The through groove 71 is fixed in conjunction with the fixed insert plate 83. The bottom of the connecting rod 7 is provided with a scraping frame 8. The scraping frame 8 serves to fix the scraping mechanism 11.

[0022] Both sides of the scraper frame 8 are provided with limiting grooves 81. The bottom ends of the two sets of connecting rods 7 are embedded in the limiting grooves 81. A first spring 82 is connected to one side of the limiting groove 81. The first spring 82 is compressed and contracted. A fixed insert plate 83 is connected to the side of the first spring 82 away from the edge of the limiting groove 81. The connecting rods 7 and the scraper frame 8 are connected by the fixed insert plate 83 embedded in the through groove 71. The scraper cylinder 5 can drive the fixed plate 6 to move up and down. The fixed plate 6 drives the scraper mechanism 11 arranged in the scraper frame 8 to scrape off the scale on the surface of the cathode plate 2. The end of the fixed insert plate 83 away from the first spring 82 is embedded in the through groove 71.

[0023] A connecting rod 84 is connected to the top of the fixed insert plate 83 near the first spring 82. The connecting rod 84 can pull the fixed insert plate 83. The end of the connecting rod 84 away from the fixed insert plate 83 passes through the limiting groove 81 and is connected to a pull block 85. When installing the scraper frame 8, pulling the pull block 85 will drive the connecting rod 84, thereby pulling the fixed insert plate 83 to the side of the first spring 82. The first spring 82 will be compressed and contracted, embedding the bottom ends of the two sets of connecting rods 7 into the limiting groove 81. The through groove 71 and the fixed insert plate 83 are connected to the first spring 82. The fixed insert plate 83 is on the same straight line. After the pull block 85 is released, the rebound action of the first spring 82 causes the fixed insert plate 83 to be embedded in the through groove 71, thereby realizing the connection between the connecting rod 7 and the scraper 8. The scraper 8 can be installed and disassembled without tools. The scraper 8 has through holes 9 at all four ends of its edge. Limiting rods 10 are fixedly connected to the inner edge of the water tank 1. The middle part of the limiting rods 10 passes through the through holes 9 for fixation. The limiting rods 10 play a limiting role.

[0024] Scaling mechanisms 11 are arranged equidistantly on the inner side of the scraping frame 8. The scraping mechanisms 11 can scrape off the scale adhering to the surface of the cathode plate 2. The scraping mechanisms 11 are staggered with the cathode plate 2. The scraping mechanism 11 includes a fixing strip 12, a scraping plate 13, a rotating hinge 14, and a second spring 15. The top two sides of the fixing strip 12 are connected to the scraping plate 13 through the rotating hinge 14. The rotating hinge 14 serves as a connection, and the fixing strip 12 serves as a fixation. The scraping plate 13 is close to the fixing strip 12. A second spring 15 is arranged on the bottom outer wall of one side. The second spring 15 provides a certain support to ensure that the scraper plate 13 and the cathode plate 2 are always in contact. The end of the second spring 15 away from the scraper plate 13 is connected to the fixing strip 12. The scraper plate 13 abuts against the cathode plate 2. The scraper cylinder 5 can drive the fixing plate 6 to move up and down. The fixing plate 6 drives the scraper frame 8, which in turn drives the scraper plate 13 to move up and down, so as to facilitate the scraping of scale on the surface of the cathode plate 2.

[0025] The outer wall of the scraper frame 8 is surrounded by an outer scraper strip 16, which abuts against the inner wall of the water tank 1. When the scraper frame 8 moves up and down, it can drive the outer scraper strip 16 to scrape and clean the inner wall of the water tank 1, so as to maintain the cleanliness of the water tank. A drain outlet 17 is provided at the center of the bottom of the water tank 1, and the scraped scale can be discharged through the drain outlet 17. A water inlet 18 is provided on one side of the outer wall of the water tank 1, and circulating water is discharged into the water tank through the water inlet 18. A water outlet 19 is provided on the side of the water tank 1 away from the water inlet 18, and the treated circulating water is discharged through the drain outlet 19.

[0026] Working principle: When using a conveniently installed negative electrode scraper roller, circulating water is discharged into the water tank through the inlet 18. After the cathode plate 2 and anode plate 3 are energized, a special electric field is formed between the cathode plate 2 and anode plate 3. Positive ions move rapidly towards the negative electrode plate, and at the same time, an alkaline environment is formed around the negative electrode plate, generating a large number of negative ions such as carbonate ions that accumulate and form scale. These negative ions combine with positive ions to quickly form scale, which is deposited on the cathode plate 2, thus treating the circulating water system. The scraping cylinder 5 can drive the fixed plate 6 to move up and down. The fixed plate 6 drives the scraping mechanism 11 arranged in the scraping frame 8 to scrape off the scale on the surface of the cathode plate 2. The scraping mechanism 11 is staggered with the cathode plate 2, and the second spring 15 provides a certain degree of support. To ensure that the scraper plate 13 and the cathode plate 2 are always in contact, the scraper frame 8 can move up and down to drive the outer scraper 16 to scrape and clean the inner wall of the water tank 1, so as to maintain the cleanliness of the water tank. When installing the scraper frame 8, pull the pull block 85. The pull block 85 drives the connecting rod 84 to pull the fixed insert plate 83 to the side of the first spring 82. The first spring 82 is compressed and contracts, embedding the bottom ends of the two sets of connecting rods 7 into the limiting groove 81. The through groove 71 and the fixed insert plate 83 are on the same straight line. After releasing the pull block 85, the rebound of the first spring 82 causes the fixed insert plate 83 to be embedded in the through groove 71, thereby realizing the connection between the connecting rod 7 and the scraper frame 8. The installation and disassembly of the scraper frame 8 can be completed without tools.
