Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to industrial circulating water descaling equipment. Background Art

[0002] At present, for industrial circulating water treatment systems in China, water stabilizing agents are generally added to increase the concentration multiples of the circulating water system, thereby reducing the amount of new water replenishment and sewage treatment; traditional water stabilizing agents mainly include: corrosion inhibitors, scale inhibitors, bactericides, etc., which are used to control scaling and corrosion of water tanks in circulating water systems. In addition to the high cost of agents used for water quality treatment and high operating costs each year, there are also the following problems: a large amount of chemical agents are used, and their transportation and storage will pollute the environment; the agents themselves will form suspended matter and precipitation in the circulating water system, polluting the circulating water quality; since the sewage contains water treatment agents, it will cause secondary pollution to the environment along with the discharge of industrial sewage.

[0003] In response to the above problems, electrochemical scale removal technology has been developed on the market. This technology is a typical active scale removal and scale inhibition technology. Its advantage is that it can precipitate scale-forming ions in water from the water body in the form of scale deposition, thereby increasing the concentration multiple of circulating cooling water, reducing the amount of sewage discharged and the amount of water replenishment, and saving water resources; however, the existing electrochemical scale removal device will simultaneously provide scrapers on both sides of the cathode plate (such as Chinese patent: 2018221777875), and the scraper is driven by a motor to rotate, resulting in the electrochemical scale removal device having many internal components and a complex structure. Therefore, the existing electrochemical scale removal device needs to be improved. Utility Model Content

The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0036] See also Figures 1 to 7 An industrial circulating water descaling device includes a water tank 100, a cathode plate 200, an anode plate 300, a scraper 400 and a driving unit 500. The cathode plate 200, the anode plate 300 and the scraper 400 are respectively arranged inside the water tank 100, and the scraper 400 is horizontally mounted on the water tank 100, and a scraping port 410 is opened in the middle of the scraper 400, and the cathode plate 200 is placed in the scraping port 410. The driving unit 500 partially extends into the water tank 100, is connected with the cathode plate 200 and the anode plate 300, and drives the cathode plate 200 and the anode plate 300 to reciprocate. When the cathode plate 200 rotates, the scale on the surface of the cathode plate 200 is scraped off by the scraping port 410 of the scraper 400.

[0037] Specifically, in this embodiment, a scraper 400 is horizontally mounted inside the water tank 100, and both ends of the scraper 400 are respectively connected to the water tank 100, and a scraping port 410 is opened in the middle of the scraper 400, and the cathode plate 200 and the anode plate 300 are also arranged in the water tank 100, and the cathode plate 200 is placed in the scraping port 410 of the scraper 400, and the driving unit 500 partially penetrates into the water tank 100 and is connected to the cathode plate 200 and the anode plate 300, and the driving unit 500 can drive the cathode plate 200 to move. 0 and the anode plate 300 rotate. When the cathode plate 200 is rotating, the scale on the surfaces of both sides of the cathode plate 200 can be scraped off through the scraping opening 410 of the scraper 400, so as to realize the automatic descaling function. By opening the scraping opening 410 on the scraper 400 and placing the cathode plate 200 in the scraping opening 410, it is possible to avoid arranging the scrapers 400 on both sides of the cathode plate 200 at the same time, thereby reducing the assembly parts of the descaling equipment, reducing the cost of parts, and making the overall structure of the descaling equipment simple and reasonable.

[0038] In addition, when the driving unit 500 drives the cathode plate 200 to rotate, the rotation mode is reciprocating, that is, the cathode plate 200 rotates one circle in the forward direction and then one circle in the reverse direction, and it only needs to reciprocate once within a certain period of time (24 hours). Of course, the specific number of reciprocating rotations and the set time can be set according to actual needs.

[0039] In order to facilitate the installation of the scraper 400, fixing strips 130 are respectively provided on the two side walls inside the water tank 100, and a first fixing hole 131 is drilled on the fixing strip 130, and second fixing holes 420 are respectively drilled at both ends of the scraper 400. During assembly, the two ends of the scraper 400 are respectively placed on the fixing strips 130 of the two side walls, and the second fixing holes 420 and the first fixing holes 131 are made to correspond to each other, and then screws are inserted into the second fixing holes 420 and the first fixing holes 131, so that the two ends of the scraper 400 can be installed on the fixing strip 130, making the installation of the scraper 400 convenient and simple.

[0040] After the scraper 400 has been descaling the cathode plate 200 for a period of time, the scraping port 410 of the scraper 400 will be worn or the scraping port 410 of the scraper 400 needs to be cleaned. At this time, the scraper 400 can be replaced or the scraping port 410 of the scraper 400 can be cleaned by unscrewing the screw to ensure the descaling effect of the scraper 400 on the cathode plate 200.

[0041] See also Figure 3In this embodiment, since the scraper 400 is fixed in the water tank 100, and the cathode plate 200 and the anode plate 300 need to rotate relative to the scraper 400, in order to realize the rotation of the cathode plate 200 and the anode plate 300, the driving unit 500 includes a motor 510 and a rotating shaft 520. The motor 510 is located outside the water tank 100, and one end of the rotating shaft 520 will penetrate into the water tank 100 and pass through the center of the cathode plate 200 and the anode plate 300 to be connected thereto, and the other end of the rotating shaft 520 is connected to the motor 510 through a gear chain 530. When the motor 510 is started, the motor 510 will drive the rotating shaft 520 to rotate. When the rotating shaft 520 rotates, it will drive the cathode plate 200 and the anode plate 300 to rotate, and the cathode plate 200 can achieve scale removal on both sides of the surface by means of the scraping port 410 of the scraper 400.

[0042] Also, see Figures 3 to 5 In this embodiment, different numbers of cathode plates 200 and anode plates 300 can be set according to the size of the water tank 100. When a plurality of cathode plates 200 and anode plates 300 are provided, the plurality of cathode plates 200 and the plurality of anode plates 300 are staggered and arranged at intervals, and the plurality of cathode plates 200 and the plurality of anode plates 300 are connected in series through a connecting rod 600, and the connecting rod 600 is made of plastic material. Of course, plastic material can also be used, and the number of scrapers 400 corresponds to the number of cathode plates 200, and each cathode plate 200 is placed in the scraping port 410 of the corresponding scraper 400.

[0043] Of course, the cathode plate 200 and the anode plate 300 need to be powered on to achieve electrochemical descaling, so some cathode plates 200 are also connected in series with cathode rods 210 with cathode current, and some anode plates 300 are connected in series with anode rods 310 with anode current, and the cathode rods 210 and the anode rods 310 are both made of copper. At the same time, one end of the cathode rod 210 and the anode rod 310 are also electrically connected to a flexible cable 700 respectively, and the flexible cable 700 extends outward from the water tank 100, and an external power source is connected through the flexible cable 700 to achieve power supply of the cathode plate 200 and the anode plate 300, so that the cathode plate 200 can adsorb insoluble substances to form a scaling layer, which is convenient for subsequent descaling.

[0044] The external cable is a flexible cable 700 with a certain length, so that the cathode plate 200 and the anode plate 300 can rotate back and forth without causing the flexible cable 700 to be pulled apart from the cathode rod 210 and the anode rod 310, thereby ensuring the electrical connection between the flexible cable 700 and the cathode rod 210 and the anode rod 310 respectively.

[0045] At the same time, since the cathode rod 210, the anode rod 310 and part of the flexible cable 700 are placed in the water tank 100, in order to perform waterproof treatment and avoid short circuit, the connection between the flexible cable 700 and the cathode rod 210 and the anode rod 310 is covered with waterproof tape. The waterproof tape is used to achieve waterproof treatment, thereby avoiding the occurrence of short circuit and improving the safety performance of the equipment.

[0046] See also Figure 5 In the present embodiment, the cathode plates 200 and the anode plates 300 are staggered, and the cathode rod 210 needs to pass through the anode plate 300 when being connected to the cathode plates 200 respectively. In order to avoid a short circuit between the cathode rod 210 and the anode plate 300, a first isolation sleeve 220 is provided at the position where the cathode rod 210 passes through the anode plate 300, and the cathode rod 210 and the anode plate 300 are isolated by the first isolation sleeve 220, thereby avoiding a short circuit. Similarly, the anode rod 310 will pass through the cathode plate 200 when being connected to the anode plates 300 respectively. Therefore, a second isolation sleeve 320 is provided at the position where the anode rod 310 passes through the cathode plate 200, and the anode rod 310 and the cathode plate 200 are isolated by the second isolation sleeve 320, thereby avoiding a short circuit. This improves safety performance and avoids failures.

[0047] Furthermore, in the present embodiment, sealing tubes 800 are provided at the intervals between the cathode plates 200 and the anode plates 300, and the connecting rods 300, the cathode rods 210 and the anode rods 310 are all located in the sealing tubes 800. The cathode rods 210 and the anode rods 310 are sealed by the sealing tubes 800 to prevent the cathode rods 210 and the anode rods 310 from contacting the circulating water, thereby avoiding short circuits and better improving the safety performance of the equipment.

[0048] Finally, see Figure 6 In order to facilitate the subsequent cleaning of the entire interior of the water tank 100, the water tank 100 in this embodiment includes a box body 110 and a top cover 120. The top cover 120 is connected to the top cover of the box body 110 and fixed by screws. After the water tank 100 has been used for a period of time, the screws can be unscrewed and the top cover 120 can be opened, thereby facilitating manual cleaning of the various components inside the water tank 100, thereby facilitating better subsequent descaling.

[0049] In this embodiment, since the water tank 100 needs to circulate water, the fixed top cover 120 and the top of the box body 110 need to be sealed. Therefore, a sealing groove 140 is set at the top of the box body 110, and a sealing ring can be installed in the sealing groove 140. The sealing of the top cover 120 and the top of the box body 110 is achieved through the sealing groove 140 and the sealing ring. A water inlet 150 is opened at one end of the box body 110, and a water outlet 160 is opened at the other end. The water circulation of the water tank is achieved through the water inlet 150 and the water outlet 160. The scale discharge port 170 at the bottom can be used to scrape scale at a set time, and then the bottom scale discharge port 170 is opened to discharge the scraped scale from the scale discharge port 170.

[0050] In addition, since the water tank 100 is in a sealed circulation state, a certain air pressure will be generated. For production safety, an exhaust valve 180 is provided on the top cover 120. The air pressure can be discharged through the exhaust valve 180, thereby ensuring the safety of the water tank 100.

[0051] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Any technician in the industry can smoothly implement the utility model according to the drawings shown in the specification and the above description; however, any equivalent changes, modifications and evolutions made by any technician familiar with the profession without departing from the scope of the technical solution of the utility model using the technical content disclosed above are all equivalent embodiments of the utility model; at the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the utility model are still within the scope of protection of the technical solution of the utility model.
