Description

Technical Field

[0001] The utility model relates to water treatment equipment, in particular to an automatic descaling electrochemical water treatment equipment. Background Art

[0002] Electrochemical water treatment equipment is a device for purifying water. Sewage acts as an electrolyte and undergoes oxidation and reduction reactions on the anode plate and cathode plate, respectively. Harmful ions in the water are removed through electrochemical electrolysis reactions, and the removed ions are deposited on the cathode plate of the electrochemical water treatment equipment to centrally clean scale. Existing electrochemical water treatment equipment cannot clean the scale on the cathode plate, and needs to be scraped multiple times.

During the scraping process, the scraper is easily misaligned with the cathode plate after it is separated from the cathode plate and then returned, which also affects the scraping work. Secondly, after scraping, there will be sludge left on the scraper, which is not easy to clean. Too much sludge accumulates at the sewage outlet, affecting sewage discharge, and needs to be cleaned manually, which causes inconvenience in use and cleaning. Utility Model Content

Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. The components of the embodiments of the utility model described and shown in the drawings herein can be arranged and designed in various different configurations.

[0029] Example 1

[0030] like Figure 1-4 As shown, an electrochemical water treatment device for automatic descaling includes an electrochemical reaction tank 1 and a hydraulic device 2. The hydraulic device 2 moves up and down through a hydraulic cylinder and is located on the left and right sides of the electrochemical reaction tank 1. There are crossbeams on the top of the two hydraulic cylinders to make the crossbeams move up and down synchronously. The electrochemical reaction tank 1 includes an anode plate 3 and a cathode plate 4. The anode plate 3 and the cathode plate 4 are fixedly installed inside the electrochemical reaction tank 1 through a fixing frame. The number of anode plates 3 and cathode plates 4 is at least one, and the positions are mutually crossed and the spacing is equal; the hydraulic device 2 includes a knife holder 5, a knife seat 6, a scraper The scraper 7, the crossbeam connected to the hydraulic device 2 can drive the tool holder 5 to move up and down, the tool holder is located outside the contour of the cathode plate 4, and the bottom of the tool holder 5 is fixed with an upper and lower knife seat 6 to increase the strength of the scraper 7 and increase the scraping efficiency. The two horizontal positions of the scraper 7 are respectively perpendicular to the two side surfaces of the cathode plate 4, and the blade head of the scraper 7 is in contact with the outer surface of the cathode plate 4. When the tool holder 5 moves down to the lowest point, the lower scraper 7 is separated from the cathode plate 4, and the upper scraper 7 is still in contact with the cathode plate, so as to avoid the lower scraper 7 and the cathode plate 4 from being misaligned and bumped during the upward movement of the scraper 7. The electrochemical reaction tank 1 also includes a water inlet 8, a water outlet 9, a sewage outlet 10, a water inlet baffle 11, and a water outlet baffle 12. Two water inlets 8 are arranged on the left side of the electrochemical reaction tank 1 to reduce the water inlet flow rate to prevent the water from rushing into the deep part of the electrochemical reaction tank 1 due to excessively fast flow. A water outlet 9 is arranged on the right side. The height of the water outlet 9 is higher than the water inlet 8, so that the sewage can be in low and out high, and the sludge can be prevented from flowing out of the water outlet 9. The bottom of the electrochemical reaction tank 1 is an inverted bucket type, which is convenient for the sludge to flow to the sewage outlet 10. A vertical water inlet baffle 11 is arranged on the side near the water inlet 8 inside the electrochemical reaction tank 1, and the weight of the debris in the sewage is used to flow to the sewage outlet as soon as possible. A vertical water outlet baffle 12 is arranged on the side near the water inlet 8, and the height of the water outlet baffle 12 is higher than the water inlet baffle 11.

[0031] During the specific implementation process, electrolytic water treatment: the electromagnetic valve of the water inlet 8 is opened to enter the sewage, and the sewage is blocked by the water inlet baffle 11 at the first time. The impurities in the sewage flow through the bottom of the sewage baffle by gravity and enter the bottom of the electrochemical reaction tank 1. The sewage passes through the top and bottom of the water inlet baffle 11 and enters the middle of the electrochemical reaction tank 1. The anode plate 3 and the cathode plate 4 are connected with direct current. The sewage passes through the anode plate 3 and the cathode plate 4, and the harmful ions in the water are adsorbed on the cathode plate 4. The scale in the sewage sinks by gravity, and the treated water passes through the top of the water outlet baffle 12 and flows out from the water outlet 9;

[0032] Scraping mud from cathode plate: After the set electrolysis water time is over, the solenoid valve of water inlet 8 is closed, and the water in electrochemical reaction tank 1 is discharged from water outlet 9 and sewage outlet 10 in sequence, the electrochemical reaction tank 1 is emptied, and the hydraulic cylinder of hydraulic device 2 is started to move the knife holder 5 downward. During this period, the upper and lower scrapers 7 scrape mud from the surface of cathode plate 4, and mud falls to the bottom of electrochemical reaction tank 1. Then the knife holder 5 is moved up to its original position by hydraulic cylinder, and the fallen sludge is collected at sewage outlet 10 for discharge.

[0033] Example 2

[0034] In order to facilitate the cleaning of the sludge adhering to the scraper 7, an improvement is made on the basis of Example 1, such as Figure 5-6 As shown, in this embodiment, the knife holder 6 includes a fixed block 14, a slot 15, a water spray pipe 16, a water spray pipe water inlet 17, and a water spray pipe nozzle 18. The fixed block 14 is located on the knife holder 6 outside the scraper 7. A semicircular slot 15 is provided on the fixed block 14. The water spray pipe 16 is buckled with the slot 15 to facilitate the disassembly and assembly of the water spray pipe 16. A water spray pipe water inlet 17 and a plurality of equidistant water spray pipe nozzles 18 are provided on the outside of the water spray pipe 16.

[0035] During the specific implementation process, when the scraper 7 is initially moving, the solenoid valve of the water inlet 17 of the water spray pipe is opened to let in water, so that the water spray nozzle 18 of the water spray pipe 16 sprays water, so that the scraper 7 will not be stuck to the accumulation of mud and dirt during the scraping process, which will affect the scraping efficiency and reduce the subsequent cleaning work of the scraper 7.

[0036] Example 3

[0037] In order to enable the water spraying nozzle 18 to flexibly adjust the water spraying angle, the embodiment 2 is improved, such as Figure 7 As shown, in this embodiment, a threaded hole 20 is penetrated on the fixing block 14 outside the slot 15 , the positioning pin 19 is threadedly connected to the threaded hole 20 , and the end of the positioning pin 19 can contact the outer wall of the water spray pipe 16 .

[0038] During the specific implementation process, when installing the water spray pipe 16, the water spray pipe 16 is rotated so that the water spray pipe nozzle 18 is directed toward the contact line between the scraper 7 and the cathode plate 4, and the position of the water spray pipe 16 is fixed by the positioning pin 19 to achieve a fixed water spray angle of the water spray pipe nozzle 18, so that the water spray angle is accurate and the cleaning efficiency is increased.

[0039] Example 4

[0040] In order to facilitate the cleaning of the sludge at the bottom of the electrochemical reaction tank 1 and the sewage outlet 10 without accumulation, improvements are made on the basis of Example 1, such as Figure 8-10 As shown, in this embodiment, a flushing device 13 is arranged at the bottom of the electrochemical reaction tank 1, and the flushing device 13 includes a main water pipe 21, a shunt pipe 22, and a cleaning device 23. The water inlet of the main water pipe 21 is controlled by a solenoid valve, and multiple horizontal shunt pipes 22 are externally connected. The outer wall of the shunt pipe 22 is provided with a nozzle, and the nozzle is directed toward the four corner grooves at the bottom of the electrochemical reaction tank 1. A cleaning device 23 is installed on the shunt pipe 22 located above the sewage outlet 10, and the cleaning device 23 is mainly used to clean the sewage outlet 10. The cleaning device 23 includes a water receiving pipe 24, a connecting pipe 25, a telescopic pipe 26, a telescopic baffle 27, a sealing sleeve 28, a spring 29, a sealing bearing 30, a rotating head 31, and a nozzle 32. The water receiving pipe 24 is vertically connected to the diversion pipe 22 and is in a vertical shape. A connecting pipe 25 is threadedly installed below the water receiving pipe 24. The telescopic pipe 26 is located in the connecting pipe 25. A telescopic baffle 27 is integrally formed on the top of the telescopic pipe 26. A sealing sleeve 28 is connected to the outer sleeve of the telescopic baffle 27 to seal with the inner wall of the connecting pipe 25. The telescopic baffle 27 is connected to the outer sleeve of the telescopic baffle 27. 7 is connected by sliding up and down inside the connecting pipe 25, the spring 29 is located in the connecting pipe 25 and below the telescopic baffle 27, so that the telescopic pipe 26 can be reset after sliding up and down, the bottom end of the telescopic pipe 26 is interference-fitted with a rotating head 31 through a sealed bearing 30, the rotating head 31 is located just above the sewage outlet 10, and the outer wall of the rotating head 31 is provided with a plurality of nozzles 32, the water spraying direction of the nozzle 32 is tangent to the outer diameter of the rotating head 31, so that when the nozzle 32 sprays water, it is affected by the water flow so that the rotating head 31 can drive the outer bristles 33 to rotate together.

[0041] During the specific implementation process, when flushing the bottom of the electrochemical reaction tank 1, the solenoid valve of the main water pipe 21 is opened and water is supplied, so that the water flows through the shunt pipe 22 to flush the four corners of the bottom of the electrochemical reaction tank 1, and the water flows into the water receiving pipe 24 in the middle part of the shunt pipe 22, and the water flows into the connecting pipe 25. The telescopic baffle 27 moves downward under the action of water pressure, and the spring 29 is compressed. The rotating head 31 moves down to the sewage outlet 10, and the water flows into the rotating head 31 along the telescopic pipe 26. The water flows out from the nozzle 32. Since the direction of the water flow is tangent to the circumference of the rotating head 31, the rotating head 31 is rotated through the sealed bearing 31 to flush the inner wall of the sewage outlet 10. During this period, the bristles 33 rotate synchronously with the rotating head 31 to wash the inner wall of the sewage outlet 10, and the stubborn sludge can be cleaned to avoid excessive sludge in the sewage outlet 10 that cannot be naturally dredged, thereby saving manual cleaning operations.

[0042] The opening and closing of the solenoid valve and the start and stop of the hydraulic cylinder involved in the above embodiments are realized under PLC control, which is the prior art and will not be described in detail.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
