Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, and specifically, to a full-automatic scale and bacteria cleaning device. Background Art

[0002] The scale and bacteria cleaner (generally referred to as an electrochemical water treatment device) is a device that uses the electrochemical properties of cations and anions in water to solve the problems of scale formation and microbial control in circulating cooling water systems. Mainly, a direct current is passed between the anode and cathode plates, and a large amount of scale is formed in the strong alkaline environment in the cathode region through the principle of electroadsorption. Strong oxidizing bactericidal substances are generated in the strong acidic environment in the anode region. By controlling the Langelier Saturation Index (LSI) and stability index of the water body, the balance of salts in the water is adjusted, so as to achieve the purpose of controlling scale formation and sterilization.

[0003] According to statistics, industrial water consumption accounts for 21.6% of the total water consumption, and the circulating water consumption accounts for 70% - 80% of the industrial water consumption. Therefore, saving the circulating cooling water consumption is the most effective measure to save industrial water. As a new type of energy-saving device, the scale and bacteria cleaner is gradually used in the field of industrial circulating water treatment to replace the original chemical agent method. After using the scale and bacteria cleaning device, the industrial circulating water system can achieve an increase in the concentration ratio (generally increased to 6 - 8 times), save water resources and solve the problem of secondary pollution. Because the system drainage does not contain the high-concentration phosphorus and bactericides brought by the agent method, and the hardness and conductivity are both greatly reduced, it is beneficial to the reuse treatment of the subsequent sewage.

[0004] In daily use, the scale and bacteria cleaning device needs to discharge the dirt in industrial water. Currently, the method of using a cylinder to drive a scraper to scrape off the dirt is adopted. However, due to the working characteristics of the cylinder, it can only act on a set of cathode plates for scale removal alone. Therefore, multiple cylinders need to work together on the overall device, resulting in a large number of air pipelines during the installation of the device, which brings great inconvenience to the overall operation and maintenance of the device. Content of the Utility Model

[0005] The utility model provides a full-automatic scale and bacteria cleaning device, which can drive the scraper to scrape off the scale on the cathode plate as a whole through the scale cleaning mechanism, with better scale removal effect, higher efficiency, and simple structure, convenient for disassembly and assembly.

[0006] Therefore, the technical solution adopted is as follows:

[0007] A fully automatic scale and bacteria cleaning device, including a device main body. Inside the device main body, there are several alternately arranged cathode plates and anode plates. It also includes a scale cleaning mechanism. The scale cleaning mechanism has two horizontally arranged lifting crossbeams. The lifting crossbeams are located above the device main body, and a lifter is fixed at each end. The lifter is driven by a driving device and drives the lifting crossbeam to move up and down. Below the lifting crossbeam, there are scrapers matching the number of cathode plates. The scrapers are close to the surface of the cathode plates, and their two ends are respectively fixed on the two groups of lifting crossbeams.

[0008] A further technical solution is that the device main body includes a main water inlet pipe. The main water inlet pipe is communicated with several sub-water inlet pipes. An emptying port is opened on the side wall of the device main body, and a slag discharge hopper is fixed at the bottom. The main water inlet pipe, the emptying port, and the slag discharge hopper are respectively controlled to open and close by a water inlet valve, an emptying valve, and a slag discharge valve.

[0009] A further technical solution is that the lifter includes a protective shell. The protective shell is fixed on the device main body. Inside the protective shell, there are a mutually matching worm gear and a worm. The worm gear is sleeved on a vertically arranged threaded rod that is thread-matched with it. The top end of the threaded rod is fixed to the lifting crossbeam, and the worm is connected to the driving device for driving.

[0010] A further technical solution is that the two groups of lifting crossbeams are arranged in parallel, and there is a transmission shaft between the two lifters on the same side of the two groups of lifting crossbeams. The two ends of the transmission shaft are respectively fixedly connected to the worms of the lifters on both sides through a coupling.

[0011] A further technical solution is that a strengthening rod perpendicular to the two groups of lifting crossbeams is connected between the two groups of lifting crossbeams. There are two strengthening rods, and they are located at both ends of the lifting crossbeams and form a rectangular frame structure with the two groups of lifting crossbeams. Guide sleeves are fixed on the strengthening rods, and a vertically arranged guide post is sleeved in the middle of the guide sleeves. The guide post is located in the middle of the strengthening rod.

[0012] A further technical solution is that the lifting crossbeam and the scraper are connected through a vertically arranged connecting column. When the lifting crossbeam is at the lowest position, the scraper is at the bottom of the device main body.

[0013] A further technical solution is that the scraper is a rectangular frame structure that sleeves the anode plate, and the outer side of the scraper is closely arranged with the cathode plates on both sides.

[0014] The working principle and beneficial effects of this application are as follows:

[0015] 1. Through the scale cleaning mechanism, the scraper is driven as a whole to scrape the scale on the cathode plate, with better descaling effect, higher efficiency, simple structure, convenient disassembly and assembly, and solves the after-sales problems such as numerous air circuits of the cylinder and easy air leakage.

[0016] 2. The descaling mechanism adopts a frame structure to combine all the scrapers into an integral structure, which has stronger integrity and stability than the original independent scraper structure and is not prone to failures.

[0017] 3. During transportation, the descaling mechanism can adjust the lifting crossbeam downward to the lowest position, effectively reducing the equipment height during transportation, preventing problems caused by transportation height limits, and the whole machine can be transported after installation and commissioning during production, reducing the maintenance work during later installation and use.

[0018] 4. The descaling mechanism has two groups of lifting crossbeams for connecting the scrapers, which act together at both ends of the scrapers, avoiding the phenomenon that when driven by a cylinder, the stress point is single, resulting in easy deformation and jamming around the scrapers during operation.

SPECIFIC EMBODIMENTS

[0028] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0029] As Figures 1 - 7 shown, a fully automatic scale and bacteria cleaning device includes a device main body 100. Inside the device main body 100, there are several alternately arranged cathode plates 101 and anode plates 102. It also includes a scale cleaning mechanism. The scale cleaning mechanism has two horizontally arranged lifting crossbeams 1. The lifting crossbeams 1 are located above the device main body 100, and a lifter 2 is fixed at each of its two ends. The lifter 2 is driven by a driving device 3 and drives the lifting crossbeam 1 to move up and down. Below the lifting crossbeam 1, there are scrapers 4 that match the number of cathode plates 101. The scrapers 4 are close to the surface of the cathode plates 101, and their two ends are respectively fixed on the two groups of lifting crossbeams 1.

[0030] Among them, the device main body 100 includes a main water inlet pipe 103. The main water inlet pipe 103 is connected to several water inlet branch pipes 104. An emptying port 105 is opened on the side wall of the device main body 100, and a slag discharge hopper 106 is fixed at the bottom. The main water inlet pipe 103, the emptying port 105, and the slag discharge hopper 106 are respectively controlled to open and close by a water inlet valve, an emptying valve, and a slag discharge valve.

[0031] During the operation of the device, first, the water inlet valve is opened. The DC power supply is linked with the water inlet valve. When the water inlet valve is opened, a start signal is given to the DC power supply, and the DC power supply starts to operate according to the set parameters. The circulating water uniformly enters the device main body 100 from the main water inlet pipe 103 through the water inlet branch pipes. Under the action of direct current, an electrochemical reaction occurs. A large amount of scale is formed in the strong alkaline environment in the cathode region, and a strongly oxidizing bactericidal substance is generated in the strong acidic environment in the anode region.

[0032] According to the set time, the water inlet valve automatically closes every once in a while. The DC power supply is linked with the water inlet valve. When the water inlet valve is closed, the DC power supply stops operating. After the water inlet valve is closed, the emptying valve is opened. After the water body inside the device main body 100 is completely emptied, the emptying valve is closed. At this time, the scale cleaning mechanism is started. The driving device 3 drives the lifters 2 at both ends to drive the lifting crossbeam 1 to move up and down. The several scrapers 4 fixed to the lifting crossbeam 1 move up and down accordingly. After repeating this several times, the scale deposited on the surface of the cathode plate 101 is scraped to the slag discharge hopper 106 at the bottom of the device main body 100. After the scale scraping is completed, the slag discharge valve is opened. After all the scale in the slag discharge hopper 106 is discharged, the water inlet valve is opened again for water flushing. After flushing for a period of time, the slag discharge valve is closed, and the device returns to the operating state to introduce circulating water for electrochemical reaction.

[0033] Through the descaling mechanism, the device drives the scraper 4 to scrape the scale on the cathode plate 101 as a whole, with better descaling effect, higher efficiency, simple structure, convenient disassembly and assembly, and solves the after-sales problems such as numerous cylinder air circuits and easy air leakage. The descaling mechanism adopts a frame structure to combine all the scrapers 4 into an integral structure, which has stronger integrity and stability than the original independent scraper 4 structure and is not prone to failure.

[0034] Moreover, when the descaling mechanism is transported, the lifting cross beam can be adjusted downward to the lowest position, effectively reducing the height of the equipment during transportation, preventing the problem of transportation height limit, and the whole machine can be transported after installation and commissioning in production, reducing the maintenance work during later installation and use. At the same time, the descaling mechanism has two groups of lifting cross beams 1 for connecting the scrapers 4, which act together at both ends of the scraper 4, avoiding the phenomenon that when driven by the cylinder, the stress point is single, resulting in easy deformation and jamming around the scraper 4 during operation.

[0035] As Figures 6 - 7 shown, the elevator 2 includes a protective shell 21, the protective shell 21 is fixed on the equipment main body 100, the inside of the protective shell 21 has a mutually matching worm gear 22 and a worm 23, the worm gear 22 is sleeved on a threaded rod 24 which is vertically arranged and thread-matched with it, the top end of the threaded rod 24 is fixed to the lifting cross beam 1, and the worm 23 is connected and driven by the driving device 3.

[0036] During operation, the driving device 3 drives the worm 23 to rotate, the worm 23 drives the worm gear 22 to rotate, so that the threaded rod 24 drives the lifting cross beam 1 to move upward. When the lifting cross beam 1 drives the scraper 4 to move to the upper part of the equipment main body 100, the driving device 3 drives the worm 23 to rotate in the reverse direction, so that the lifting cross beam 1 descends to the initial position, and so on. The driving device 3 adopts the combination of a servo motor and a planetary reducer, and then uses the reduction ratio of the worm gear 22 and the worm 23 of the elevator 2 to reduce the lifting speed of the scraper 4. Compared with the high-speed push of the cylinder, the scraper 4 runs more smoothly and can reduce energy consumption.

[0037] As Figures 2 - 3 shown, the two groups of lifting cross beams 1 are arranged in parallel, and there is a transmission shaft 5 between two elevators 2 on the same side of the two groups of lifting cross beams 1. Both ends of the transmission shaft 5 are respectively fixed to the worms 23 of the elevators 2 on both sides through a coupling 6. A reinforcing rod 7 perpendicular to the two is connected between the two groups of lifting cross beams 1. There are two reinforcing rods 7, which are located at both ends of the lifting cross beam 1 and form a rectangular frame structure with the two groups of lifting cross beams 1. A guide sleeve 71 is fixed on the reinforcing rod 7, and a vertically arranged guide post 72 is sleeved in the middle of the guide sleeve 71. The guide post 72 is located in the middle of the reinforcing rod 7.

[0038] Through the transmission rod, the two groups of elevators 2 can be driven synchronously, further ensuring the synchronization and stability of the movement of the two groups of lifting crossbeams 1. Moreover, the connection strength of the lifting crossbeam 1 is ensured by the strengthening rod 7, and the linear state of the lifting crossbeam 1 during operation is ensured by the guide post 72, further maintaining the stable operation of the descaling mechanism and preventing deformation.

[0039] As Figures 4 - 5 shown, the lifting crossbeam 1 and the scraper 4 are connected by a vertically arranged connecting column 8. When the lifting crossbeam 1 is in the lowest position, the scraper 4 is located at the bottom of the equipment main body 100. As Figures 1 - 2 shown, the scraper 4 is a rectangular frame structure in which the anode plate 102 is sleeved, and the outer side of the scraper 4 is closely arranged with the cathode plates 101 on both sides. Thus, the lifting crossbeam 1 is always located above the equipment main body 100, will not interfere with the cathode plates 101 and anode plates 102 inside the equipment main body 100, and is convenient for installation and disassembly.

[0040] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
