Description

Technical Field

[0001] This utility model relates to the field of sodium hypochlorite generators, and in particular to a cleaning device for the electrolytic plates of a sodium hypochlorite generator. Background Technology

[0002] A sodium hypochlorite generator is a device used to prepare sodium hypochlorite, a sterilizing agent for water bodies. Existing sodium hypochlorite generators first dissolve salt to prepare a saturated sodium chloride solution, then dilute the saturated sodium chloride solution to a specific concentration. During operation, the diluted sodium chloride solution is fed into an electrolytic cell containing electrolytic plates connecting the positive and negative electrodes. The sodium chloride solution is electrolyzed to produce a sodium hypochlorite solution.

[0003] During long-term electrolysis, calcium and magnesium ions will form scale on the electrolytic plates. This not only reduces electrolysis efficiency and increases power consumption, but also increases the heat generated during electrolysis, leading to a rise in the temperature inside the electrolytic cell and affecting the stability of the sodium hypochlorite solution. Therefore, after the sodium hypochlorite generator has been operating for a period of time, electrolysis needs to be stopped for maintenance. The electrolytic cell should be disassembled, the electrolytic plates replaced, and the scaled electrolytic plates should be dissolved and cleaned by soaking in hydrochloric acid.

[0004] To ensure effective cleaning, electrolytic plates need to be soaked in acid for an extended period and manually turned over to ensure that all scale on the plate surface dissolves and detaches. However, with a large number of electrolytic plates being replaced periodically, prolonged soaking is inefficient, and manually turning the plates in acid poses safety hazards. Therefore, a new cleaning method is needed to clean and remove scale from electrolytic plates that have been replaced in batches. Utility Model Content

[0005] To address the problems existing in the prior art, such as the low efficiency and safety hazards of cleaning electrolytic plates by prolonged immersion in acid, this utility model aims to provide a cleaning device for electrolytic plates of sodium hypochlorite generators. This device uses a tray to simultaneously immerse numerous electrolytic plates in an immersion tank containing acid, while a polarization mechanism drives the entire tray to vibrate, significantly improving the cleaning efficiency of the electrolytic plates.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: A cleaning device for electrolytic plates of a sodium hypochlorite generator includes an immersion tank, a polarization mechanism, a tray, and a drive mechanism. The immersion tank has a removable cover plate on top, and the polarization mechanism is mounted on the cover plate and located below it. The polarization mechanism includes a drive shaft, a vibrating cylinder, and an eccentric block. The drive shaft and eccentric block are located inside the vibrating cylinder, and the eccentric block is fixed to the side of the drive shaft.

The top of the drive shaft extends upward through the cover plate, and the drive mechanism is located above the cover plate, driving the drive shaft to rotate. The immersion tank contains a cleaning solution with the liquid level higher than the electrolytic plates on the tray.

[0007] The present invention is further configured such that: a first connector is provided at the top of the transmission shaft; the driving mechanism includes a driving component and a second connector; the driving component is fixedly connected to the second connector and drives the second connector to rotate; the first connector and the second connector can be plugged in and engaged.

[0020] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] As attached Figure 1-3 As shown, a cleaning device for the electrolytic plates of a sodium hypochlorite generator is used to clean the electrolytic plates 1. It includes an immersion tank 2, a polarization mechanism 3, a tray 4, and a drive mechanism 5.

[0022] Electrolytic plate 1 is a rectangular sheet structure, and immersion tank 2 is a rectangular box containing hydrochloric acid cleaning solution for cleaning electrolytic plate 1.

[0023] The top of the immersion tank 2 is equipped with a removable cover plate 21. The cover plate 21 is adapted to the size and shape of the immersion tank 2, so that it can be placed on the immersion tank 2 to prevent the acid solution inside from splashing out of the immersion tank 2. It is understood that all structures in this utility model that come into direct contact with the hydrochloric acid cleaning solution are made of acid-resistant materials, such as polypropylene, polyvinyl chloride, polytetrafluoroethylene, etc.

[0024] The polarization mechanism 3 is installed at the center of the cover plate 21 and is located below the cover plate 21. Specifically, the polarization mechanism 3 includes a drive shaft 31, a fixing block 32, a vibrating cylinder 33, a sealing sleeve 34, and an eccentric block 36. The drive shaft 31 is a vertically arranged rotating shaft located at the center of the polarization mechanism 3. The top of the drive shaft 31 extends upward through the cover plate 21, and the top of the drive shaft 31 is provided with a first connector 312 for connecting with the drive mechanism 5.

[0025] A fixing block 32 is also provided on the periphery of the drive shaft 31 located above the cover plate 21. The fixing block 32 is a cylindrical structure, and its axis coincides with the axis of the drive shaft 31. The bottom of the fixing block 32 is fixedly connected to the cover plate 21, and a bearing 321 is also provided between the fixing block 32 and the drive shaft 31.

[0026] The bottom of the drive shaft 31 and the eccentric block 36 are both located inside the vibrating cylinder 33. The vibrating cylinder 33 is a cylindrical structure with only a top opening, and the axis of the vibrating cylinder 33 coincides with the axis of the drive shaft 31.

[0027] Inside the vibrating cylinder 33, two fixing blocks 32 are also provided, which are sleeved on the outside of the drive shaft 31. The two fixing blocks 32 are located in the middle and bottom of the vibrating cylinder 33, respectively. Each fixing block 32 is provided with a bearing 321 between itself and the drive shaft 31. The side wall of the fixing block 32 in the vibrating cylinder 33 is in direct contact with and fixedly connected to the vibrating cylinder 33.

[0028] The eccentric block 36 is fixed to one side of the drive shaft 31, and its vertical position is between the two fixed blocks 32 in the vibrating cylinder 33. Both the eccentric block 36 and the drive shaft 31 are made of steel. The eccentric block 36 is relatively heavy, thus it can generate high-frequency vibration under the drive of the drive shaft 31.

[0029] A spring-loaded flexible shaft 311 is also provided in the middle section of the drive shaft 31. The spring-loaded flexible shaft 311 is located below the cover plate 21 and above the eccentric block 36. The eccentric flexible shaft is an existing structure that can reduce the impact of vibration at the bottom of the drive shaft 31 on the top of the drive shaft 31 while transmitting torque normally.

[0030] The sealing sleeve 34 is a cylindrical structure whose axis coincides with the axis of the vibrating cylinder 33. Its top is fixedly connected to the lower surface of the cover plate 21, and its bottom is fixedly connected to the top of the vibrating cylinder 33.

[0031] The sealing sleeve 34 is made of a flexible rubber material resistant to acid and alkali corrosion, such as fluorosilicone rubber. The sealing sleeve 34 protects the drive shaft 31 during the operation of the polarization mechanism 3, preventing acid solution in the immersion tank 2 from splashing onto the drive shaft 31. Simultaneously, the sealing sleeve 34 prevents the vibrating cylinder 33 from directly contacting the cover plate 21, thus reducing the impact of the vibration of the vibrating cylinder 33 on the cover plate 21 and other structures in direct contact with it.

[0032] The polarization mechanism 3 also includes a suspension assembly 35, which is used to support the weight of the vibrating cylinder 33 and the tray 4 fixedly connected to the vibrating cylinder 33. The suspension assembly 35 is located inside the vibrating cylinder 33 and the sealing sleeve 34.

[0033] Specifically, the suspension assembly 35 includes hanging rings 351 and slings 352. Each set of hanging rings 351 consists of two corresponding rings, one above the other, in the vertical direction. The upper hanging rings 351 are fixed to the lower surface of the cover plate 21, while the lower hanging rings 351 are fixed to the vibrating cylinder 33. In this embodiment, the lower hanging rings 351 are fixed to the fixing block 32. Each set of hanging rings 351 corresponds to one sling 352, which connects the upper and lower hanging rings 351. The slings 352 can reduce the impact of the vibration of the vibrating cylinder 33 on the cover plate 21 while bearing the weight of the vibrating cylinder 33 and the tray 4.

[0034] The tray 4 is used to place the electrolytic plate 1. When the cover plate 21 is placed on the soaking tank 2, the tray 4 is completely inserted into the soaking tank 2. At this time, the liquid level of the hydrochloric acid cleaning solution in the soaking tank 2 should be higher than the top of the electrolytic plate 1 on the tray 4 and lower than the bottom of the sealing sleeve 34.

[0035] As attached Figure 3-4 As shown, the tray 4 is a cuboid structure with a circular through hole at its center that matches the outer diameter of the vibrating cylinder 33, so that the tray 4 can be fixedly connected to the vibrating cylinder 33, and the fixed position of the tray 4 is located on the periphery of the eccentric block 36.

[0036] The tray 4 is provided with several cleaning slots 41 for placing electrolytic plates 1. The cleaning slots 41 on the tray 4 are spaced apart to prevent the electrolytic plates 1 in two adjacent cleaning slots 41 from contacting each other. The cleaning slots 41 are slightly larger than the electrolytic plates 1 in the horizontal direction, so each cleaning slot 41 can only hold one electrolytic plate 1.

[0037] The cleaning tank 41 extends vertically through the tray 4, and each cleaning tank 41 has a connecting rod 42 at its bottom for supporting and limiting the electrolytic plate 1. The connecting rod 42 is a short cylindrical rod with its length direction perpendicular to the length direction of the cleaning tank 41. This facilitates the entry of hydrochloric acid cleaning solution into the cleaning tank 41 when the tray 4 is submerged, and also prevents clumps of scale that have detached from the electrolytic plate 1 from accumulating in the cleaning tank 41.

[0038] As attached Figure 1-3 As shown in Figures 5-6, the drive mechanism 5 is located above the cover plate 21. The drive mechanism 5 includes a motor 51, a support plate 52, and a second connector 53.

[0039] The support plate 52 is a cylindrical structure with a protective sleeve 521 along its axis. The motor 51 is mounted and fixed on the support plate 52, and the output shaft of the motor 51 and the second connector 53 fixed on the output shaft of the motor 51 are located inside the protective sleeve 521.

[0040] The second connector 53 is a cylindrical block structure with a vertically concave bottom forming a cuboid-shaped recess. The first connector 312 at the top of the drive shaft 31 is a matching cuboid block structure, allowing it to be vertically inserted into the recess on the second connector 53 and engaged. When the motor 51 is powered on, torque is transmitted to the drive shaft 31 through the second connector 53 and the first connector 312.

[0041] The implementation principle of the above embodiments is as follows: When batch cleaning of electrolytic plates 1 is required, the electrolytic plates 1 are placed sequentially into the cleaning tank 41 on the tray 4, and then the cover plate 21 is slowly placed on the soaking tank 2. During this process, the tray 4 and the electrolytic plates 1 are completely immersed in the hydrochloric acid cleaning solution. After the cover plate 21 is completely in place, the protective cylinder 521 on the support plate 52 is aligned with the fixing block 32 on the cover plate 21, and the drive mechanism 5 is placed on the cover plate 21. The position of the support plate 52 is adjusted until the first connector 312 is fully inserted into the second connector 53. At this time, the power supply of the motor 51 can be turned on, and the motor 51 drives the transmission shaft 31 to rotate. Under the action of the eccentric block 36, high-frequency vibration is generated. The vibration is transmitted to each electrolytic plate 1 on the tray 4 through the vibrating cylinder 33, thereby accelerating the dissolution and removal of scale.

[0042] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including both the preferred embodiments and all changes and modifications falling within the scope of the present invention. Clearly, those skilled in the art can make various alterations and modifications to the present invention without departing from its spirit and scope. Thus, if such modifications and modifications fall within the scope of the claims of the present invention and their equivalents, the present invention also intends to include such modifications and modifications.
