Description

Technical Field

[0001] This utility model relates to the field of sodium hypochlorite production equipment, and in particular to a salt tank cleaning system. Background Technology

[0002] Sodium hypochlorite is a highly efficient, broad-spectrum, and safe sterilizing agent. However, its stability is relatively poor, and it cannot be stored for long periods. Therefore, sodium hypochlorite solutions used for water disinfection are mostly produced on-site using sodium hypochlorite generators for immediate use. Currently, sodium hypochlorite generators produce sodium hypochlorite solutions by electrolyzing uniodized saline solution.

[0003] Before the sodium hypochlorite generator operates, salt is dissolved to prepare a saturated sodium chloride solution. This saturated sodium chloride solution is then diluted to a 2%-3% sodium chloride solution. During operation, the sodium chloride solution is fed into an electrolytic cell containing positive and negative electrodes. The sodium chloride solution is electrolyzed to form a sodium hypochlorite solution. To continuously supply the sodium hypochlorite generator with saturated brine, a salt tank is often built-in or externally connected to the generator to dissolve solid salt and prepare the saturated sodium chloride solution.

[0004] The salt tank is connected to an external water supply pipe, allowing for timely replenishment of water when the salt level drops. Simultaneously, the salt tank must maintain a sufficient amount of solid salt to ensure a saturated sodium chloride solution is supplied to the sodium hypochlorite generator. The top of the salt tank is equipped with a resealable cover that can be opened. When the operator finds the remaining solid salt level insufficient, the cover must be manually opened to pour the solid salt into the tank.

[0005] The aforementioned method of manually checking the remaining amount of solid salt in the salt tank involves directly opening the sealed cover to observe the bottom of the tank. Similarly, adding solid salt to the tank also requires opening the sealed cover. During frequent opening of the sealed cover, foreign matter adhering to the solid salt packaging, impurities in the working environment of the sodium hypochlorite generator, and debris such as hair from the operator can easily enter the salt tank. Excessive impurities in the salt tank pose a risk of flowing into the sodium hypochlorite generator, potentially clogging pipes or even entering the electrolytic cell. However, once the sodium hypochlorite generator is put into use, the salt tank remains connected to it and continuously stores sodium chloride solution, making disassembly and cleaning impossible. Therefore, a dedicated device for removing foreign matter from the salt tank is needed. Utility Model Content

[0006] To address the problems existing in the prior art, such as the inability to disassemble and clean salt tanks during long-term use leading to the accumulation of impurities and foreign objects at the bottom of the salt tank, this utility model aims to provide a salt tank cleaning system. By installing a water intake pipe and a water return pipe with valves at the bottom of the salt tank, when cleaning is required, the circulation pump and circulation loop in the mobile cleaning mechanism are connected to the water intake pipe and the water return pipe. At the same time, a filter mechanism is installed in the circulation loop, thereby drawing out impurities and foreign objects from the bottom of the salt tank and intercepting them in the filter mechanism. Thus, the salt tank can be cleaned without disassembling it.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows: A brine tank cleaning system includes a fixed cleaning mechanism, a mobile cleaning mechanism, and a filtration mechanism. The fixed cleaning mechanism is installed on the brine tank and includes a first pumping pipe and a first return pipe, both connected to the brine tank, with the first pumping pipe connected to the bottom of the brine tank. The mobile cleaning mechanism includes a circulation pump and a circulation loop. The circulation pump is connected to the first pumping pipe and pumps brine from the brine tank into the circulation loop. The two ends of the circulation loop are connected to the first return pipe and the circulation pump, respectively. The filtration mechanism is installed on the circulation loop and is detachably connected to the circulation loop. The filtration mechanism is used to filter the brine in the circulation loop.

[0008] The present invention is further configured such that: the fixed cleaning mechanism also includes a spray pipe and a nozzle, one end of the spray pipe is connected to the first return water pipe and the other end is connected to the nozzle, and the nozzle is aligned with the bottom of the salt tank and close to the bottom of the salt tank.

[0009] The present invention is further configured such that: the first return water pipe extends into the interior of the salt tank, and the first return water pipe is simultaneously connected to two or more spray pipes.

[0010] The present invention is further configured such that: a pumping valve is provided on the first pumping pipe, and a return valve is provided on the first return pipe.

[0011] The present invention is further configured such that: the bottom of the salt tank is provided with an isolation cavity and a flap, the isolation cavity is recessed into the side wall of the salt tank, the top of the flap is hinged to the side wall of the salt tank, the first water pump pipe and the first water return pipe are both located in the isolation cavity, and the flap is used to close or open the isolation cavity.

[0012] The present invention is further configured such that: a front valve and a rear valve are provided on the circulation loop, and the filter mechanism is installed between the front valve and the rear valve.

[0013] The present invention is further configured such that: the filtration mechanism includes a filter cylinder and a filter screen fixed inside the filter cylinder, the water flow direction inside the filter cylinder is vertically upward, and the filter screen is horizontally arranged.

[0014] The present invention is further configured such that: the filtration mechanism includes two or more filter cylinders, each filter cylinder having a different mesh size of the filter screen, and each filter cylinder can be installed individually on the circulation loop.

[0015] The present invention is further configured such that: the filtration mechanism is formed by two or more filter cylinders connected in series, and the mesh size of the filter screen in each filter cylinder is different.

[0016] The present invention is further configured such that: the filtration mechanism is formed by two or more filter cylinders connected in parallel, and the mesh size of the filter screen in each filter cylinder is different.

[0017] In summary, the beneficial effects achieved by this utility model are as follows: (1) The fixed cleaning mechanism consists only of a nozzle, a first pumping pipe, and a first return pipe. It has a simple structure and low cost. It can be directly installed at the bottom of each salt tank without affecting the normal use of the salt tank. When there are many impurities and foreign objects accumulated in the salt tank and cleaning is required, the fixed cleaning mechanism on each salt tank can be connected to the same mobile cleaning mechanism in sequence to form a circulation pipeline of salt tank-first pumping pipe-circulation pump-circulation loop-first return pipe-salt tank. During the circulation process, the impurities and foreign objects at the bottom of the salt tank are temporarily suspended by the impact of the water flow sprayed from the nozzle. They are then pumped away by the first pumping pipe and finally intercepted and retained in the filter mechanism in the circulation loop, thus achieving the cleaning of the salt tank. (2) The isolation chamber that accommodates the first pumping pipe, the first return pipe and the valve is recessed into the side wall of the salt tank. While protecting the first pumping pipe, the first return pipe and the valve, it not only avoids expanding the space occupied by the salt tank, but also reduces the area of ​​the accumulation of impurities and foreign objects at the bottom of the salt tank, which is conducive to the extraction of impurities and foreign objects. (3) The filter mechanism on the circulation loop is detachably connected, so that the filter mechanism that has collected impurities and foreign objects can be replaced in a timely manner; (4) The water flow direction inside the filter cylinder is vertically upward, while the filter screen is set horizontally, which improves the interception effect of the filtration mechanism on impurities and foreign objects; (5) The filtration mechanism includes several filter cylinders with different mesh sizes. When only a single filter cylinder is installed in the circulation loop, different filter cylinders can be replaced in a manner that decreases the mesh size for the same salt tank, thereby achieving step-by-step filtration and interception of impurities and foreign objects, improving the cleaning effect while avoiding filter clogging. When multiple filter cylinders can be installed in the circulation loop at the same time, the filter cylinders can be combined in series or in parallel according to the mesh size to achieve diversified filtration and interception of impurities and foreign objects.

For ease of explanation, the terms "vertical", "horizontal", "left", "right", "upper", "lower", "inner", "outer", "bottom", etc., used in this specification indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0022] It should be noted that the embodiments and features involved in the embodiments of this utility model can be combined with each other without conflict. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0023] As attached Figure 1-3 As shown, a salt tank cleaning system includes a fixed cleaning mechanism 2, a movable cleaning mechanism 3, and a filtration mechanism 4.

[0024] The salt tank 1 is a vertically oriented rectangular cylindrical structure with a sealing cap 13 on top and a thickened base 14 at the bottom. An inlet pipe 11 and an outlet pipe 12 are installed on the side wall of the salt tank 1, both of which are connected to the salt tank 1. The inlet pipe 11 is used to replenish water into the salt tank 1 when the liquid level drops, and the outlet pipe 12 is connected to a sodium hypochlorite generator to supply it with a saturated sodium chloride solution.

[0025] The bottom of the salt tank 1 is provided with an isolation chamber 15 and a flap 17.

[0026] The isolation chamber 15 is a cavity recessed into the side wall of the salt tank 1, used to accommodate and protect the fixed cleaning mechanism 2.

[0027] The shape and size of the flap 17 are adapted to the opening of the isolation chamber 15, and the top of the flap 17 is hinged to the side wall of the salt tank 1 at the top of the isolation chamber 15. Specifically, the flap 17 is hinged to the side wall of the salt tank 1 via two hinges. Under the action of gravity, the flap 17 hangs down naturally and remains vertical, thereby closing the isolation chamber 15. When cleaning is required, rotating the flap 17 opens the isolation chamber 15, allowing the cleaning mechanism 2 to be connected and fixed.

[0028] Specifically, the side wall of the salt tank 1 at the top of the isolation chamber 15 is a guide plate 16, which is inclined so that impurities and foreign objects falling on the guide plate 16 can naturally slide down to the bottom of the salt tank 1.

[0029] The fixed cleaning mechanism 2 is installed on the salt tank 1. The fixed cleaning mechanism 2 includes a first water pumping pipe 21, a first water return pipe 22, a spray pipe 23, and a spray head 24.

[0030] Both the first pumping pipe 21 and the first return pipe 22 are located inside the isolation chamber 15 and are connected to the salt tank 1, with the first pumping pipe 21 connected to the bottom of the salt tank 1. A pumping valve 211 is provided on the first pumping pipe 21, which is used to control the opening and closing of the first pumping pipe 21 and to connect to the mobile cleaning mechanism 3.

[0031] The first return water pipe 22 is also equipped with a return water valve 221 for controlling the opening and closing of the first return water pipe 22 and connecting to the movable cleaning mechanism 3. The first return water pipe 22 extends horizontally into the salt tank 1 and is simultaneously connected to two spray pipes 23.

[0032] The diameter of the nozzle 23 is smaller than that of the first return water pipe 22. The top end of the vertically arranged nozzle 23 is connected to the first return water pipe 22, and the bottom end is connected to the nozzle head 24. Both nozzles 23 are located in the middle of the salt tank 1 and are spaced apart.

[0033] In other embodiments, the first return water pipe 22 connects to a plurality of nozzles 23, and all nozzles 23 are evenly distributed at the bottom of the salt tank 1.

[0034] The nozzle 24 has a small hole and is vertically downward, aimed at the bottom of the salt tank 1 and close to the bottom of the salt tank 1.

[0035] The outlet pipe 12 is positioned higher than the first return pipe 22 to prevent impurities at the bottom of the salt tank 1 from entering the outlet pipe 12.

[0036] The mobile cleaning mechanism 3 is designed to be portable, and it only docks with the fixed cleaning mechanism 2 on the salt tank 1 when cleaning is required. The mobile cleaning mechanism 3 includes a circulation pump 31 and a circulation loop, which consists of a second pumping pipe 32, a third pumping pipe 34, a front valve 35, a rear valve 36, a third return pipe 37, and a second return pipe 33.

[0037] The circulating pump 31 is existing technology, so its structure will not be described in detail. The inlet end of the circulating pump 31 is connected to the second pumping pipe 32, and the outlet end of the circulating pump 31 is connected to the third pumping pipe 34. During cleaning, the second pumping pipe 32 can be connected to the first pumping pipe 21 through the pumping valve 211. After the circulating pump 31 is powered on, it can draw out the brine from the brine tank 1 and pump it into the circulation loop.

[0038] The extension direction of the second pumping pipe 32 is consistent with that of the first pumping pipe 21, and the extension direction of the second return pipe 33 is consistent with that of the first return pipe 22.

[0039] The third pumping pipe 34 is used to connect the circulating pump 31 and the front valve 35, and the third return pipe 37 is used to connect the rear valve 36 and the second return pipe 33. The third pumping pipe 34 and the third return pipe 37 can be made into flexible hoses to facilitate the smooth flow of brine.

[0040] The filter mechanism 4 is installed between the front valve 35 and the rear valve 36 in the circulation loop, and the filter mechanism 4 is detachably connected to the circulation loop through the front valve 35 and the rear valve 36. When the circulation pump 31 is working, the filter mechanism 4 can filter the brine in the circulation loop and intercept impurities and foreign objects in the brine within the filter mechanism 4.

[0041] Specifically, the filtration mechanism 4 includes a filter cylinder 41 and a filter screen 42 fixed inside the filter cylinder 41. The filter cylinder 41 is a vertically arranged cylindrical structure, and the filter screen 42 is horizontally arranged inside the filter cylinder 41 and located in the upper middle part of the filter cylinder 41. When the filter cylinder 41 is installed in the circulation loop, the water flowing through the filter cylinder 41 flows vertically upward. Impurities and foreign objects enter the filter cylinder 41 with the water flow and are intercepted by the filter screen 42, thus accumulating in the lower middle part of the filter cylinder 41. The fixed position of the filter screen 42 allows the filter cylinder 41 to hold more impurities and foreign objects.

[0042] In some other embodiments, the filtration mechanism 4 includes two or more filter cartridges 41. Each filter cartridge 41 contains a filter screen 42 with a different mesh size, and each filter cartridge 41 can be individually installed on the circulation loop. When cleaning the same salt tank 1, different filter cartridges 41 can be replaced sequentially according to decreasing mesh size, thereby achieving step-by-step filtration and interception of impurities and foreign objects of different particle sizes within the salt tank 1, improving the cleaning effect while preventing filter screen 42 from clogging.

[0043] As attached Figure 4 As shown, in some other embodiments, the filtration mechanism 4 is formed by two or more filter cartridges 41 connected in series, and the mesh size of the filter screen 42 in each filter cartridge 41 is different. The filter screen 42 in the filter cartridge 41 located at the upstream end of the circulation loop has the largest mesh size, and the filter screen 42 in the filter cartridge 41 located at the downstream end of the circulation loop has the smallest mesh size. This can still achieve the above-mentioned step-by-step filtration and interception effect, and there is no need to replace different filter cartridges 41 by closing the front valve 35, the rear valve 36 and the circulation pump 31 each time.

[0044] As attached Figure 5 As shown, in some other embodiments, the filtration mechanism 4 is formed by two or more filter cylinders 41 connected in parallel. The mesh size of the filter screen 42 in each filter cylinder 41 is different, and a valve is provided upstream of each filter cylinder 41. In this case, different valves can be opened sequentially according to the mesh size of the filter screen 42. That is, after all the larger impurity particles in the salt tank 1 are intercepted in the filter cylinder 41 with the largest mesh size, the valve corresponding to the filter cylinder 41 with the smaller mesh size is then opened, which can also achieve the above-mentioned step-by-step filtration and interception effect.

[0045] The implementation principle of the above embodiments is as follows: When a large amount of impurities and foreign matter accumulates at the bottom of the brine tank 1 and needs to be cleaned, rotate the flap 17 to open the isolation chamber 15, connect the second water pump 32 to the water pump valve 211, and simultaneously connect the second return water pipe 33 to the return water valve 221; then open the water pump valve 211, the return water valve 221, the front valve 35, and the rear valve 36, and then start the circulation pump 31. Under the action of the circulation pump 31, the brine at the bottom of the brine tank 1 returns to the brine tank 1 along the path of the first water pump pipe 21 - the second water pump pipe 32 - the circulation pump 31 - the third water pump pipe 34 - the front valve 35 - the filter cartridge 41 - the rear valve 36 - the third return water pipe 37 - the second return water pipe 33 - the first return water pipe 22 - the spray pipe 23 - the nozzle 24. During the circulation process, impurities and foreign objects at the bottom of the brine tank 1 are temporarily suspended by the impact of the water flow from the nozzle 24, and are then drawn away by the first water pipe 21. Finally, they are intercepted and remain in the filter cartridge 41 during the circulation process, thus cleaning the brine tank 1. During the cleaning process, different filter cartridges 41 can be disassembled and replaced after closing the front valve 35, the rear valve 36, and the circulation pump 31, thereby improving the cleaning effect. The impurities and foreign objects in the replaced filter cartridges 41 can be cleaned and reused.

[0046] 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.
