Description

Technical Field

[0001] This utility model relates to the field of sodium hypochlorite generators, and more particularly to a structure for maintaining the concentration of sodium chloride solution. 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 before operation, and 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 two electrodes, a positive and a negative electrode. The sodium chloride solution is electrolyzed to form a sodium hypochlorite solution.

[0003] To continuously supply saturated brine to the sodium hypochlorite generator, the generator often has a built-in or external salt tank for dissolving solid salt to prepare a saturated sodium chloride solution. 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 maintains an excess of solid salt to ensure a saturated sodium chloride solution. The top of the salt tank has a sealed cover that can be opened to allow operators to pour in more solid salt when the remaining amount is insufficient.

[0004] During the dilution process, the sodium hypochlorite generator cannot determine the required water volume based on the actual concentration of the sodium chloride solution; it can only determine the volume based on the flow rate of the saturated sodium chloride solution. Under normal circumstances, excess solid salt in the salt tank ensures that the sodium hypochlorite generator receives a saturated sodium chloride solution. However, if water is added to the salt tank via the replenishment pipe, or if the operator fails to replenish the salt tank with solid salt in a timely manner, the sodium chloride solution flowing into the sodium hypochlorite generator may not be saturated. This results in excessive dilution of the sodium chloride solution within the generator, thus affecting the electrolysis process. Therefore, improvements to the existing equipment are necessary to ensure that the sodium hypochlorite generator receives a saturated sodium chloride solution. Utility Model Content

[0005] To address the problems existing in the prior art, where the sodium chloride solution supplied to the sodium chlorate generator by the salt tank is not saturated under conditions of water replenishment and salt shortage, the purpose of this invention is to provide a sodium chloride solution concentration maintenance structure. By setting a salt replenishment mechanism on the connecting pipe between the salt tank and the sodium chlorate generator, the sodium chloride solution flowing out of the salt tank is replenished with salt a second time. At the same time, a stirring mechanism is set to ensure that the secondary salt replenishment can be completely dissolved, thereby achieving the effect of maintaining a saturated sodium chloride solution concentration.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: A sodium chloride solution concentration maintenance structure includes a salt replenishment mechanism, a connecting pipeline, and a stirring mechanism. The two ends of the connecting pipeline are respectively connected to a sodium hypochlorite generator and a salt tank. The salt replenishment mechanism includes a salt container and a salt dissolving pipe. The salt container is connected to the salt dissolving pipe and stores salt particles. The salt dissolving pipe has several evenly distributed small holes and extends into the connecting pipeline. The stirring mechanism is located on the connecting pipeline and downstream of the salt replenishment mechanism. The stirring mechanism includes a stirring tank, a motor, and a paddle. The stirring tank is connected to the connecting pipeline, and the paddle is located inside the stirring tank at its bottom. The motor drives the paddle to rotate.

[0007] The present invention is further configured such that: the salt replenishment mechanism includes a salt replenishment pipe and an installation pipe, the salt replenishment pipe is located on the connecting pipe, the installation pipe is perpendicular to the salt replenishment pipe and communicates with the salt replenishment pipe, the installation pipe is connected and fixed to the salt dissolving pipe, and the bottom end of the salt tank is provided with an installation head communicating with the salt tank, the installation head can be inserted into the installation pipe and threadedly engaged with the installation pipe.

[0008] The present invention is further configured such that the salt container is made of a transparent material.

[0009] The present invention is further configured such that a control valve is provided on the connecting pipeline, and the control valve is located upstream of the salt replenishment pipe.

[0010] The present invention is further configured such that: a connecting hose is also provided on the connecting pipeline, the two ends of the connecting hose are respectively connected to the salt replenishment pipe and the mixing tank, and the connection position between the connecting hose and the mixing tank is located at the bottom of the mixing tank.

[0011] The present invention is further configured such that the height of the connection position between the connecting hose and the salt replenishment pipe is higher than the connection position between the connecting hose and the mixing tank.

[0012] The present invention is further configured such that: the connecting pipe between the mixing tank and the salt replenishment mechanism is located at the bottom of the mixing tank, and the connecting pipe between the mixing tank and the sodium hypochlorite generator is located at the top of the mixing tank.

[0013] The present invention is further configured such that: the stirring mechanism also includes a collecting pipe and a drain valve, the collecting pipe is vertically arranged at the bottom of the stirring tank, and the drain valve is located at the bottom of the collecting pipe and communicates with the collecting pipe.

[0014] In summary, the beneficial effects achieved by this utility model are as follows: (1) Both the salt replenishment mechanism and the stirring mechanism are installed on the connecting pipe that supplies sodium chloride solution from the salt tank to the sodium hypochlorite generator. The salt particles in the salt tank enter the connecting pipe through the salt dissolving pipe and come into contact with the sodium chloride solution flowing in the connecting pipe. If the sodium chloride solution is unsaturated, the salt particles in the salt dissolving pipe can dissolve to increase the concentration of the sodium chloride solution. At the same time, driven by the flowing sodium chloride solution, a small amount of undissolved salt particles will flow out from the small holes on the salt dissolving pipe and enter the stirring tank along with the sodium chloride solution. Salt particles accumulate at the bottom of the stirring tank. If the sodium chloride solution is still unsaturated, the salt particles can dissolve quickly under the action of the impeller, thereby rapidly increasing the concentration of the sodium chloride solution to saturation. (2) The height of the connection point between the connecting hose and the salt replenishment pipe is higher than the connection point between the connecting hose and the mixing tank, so that the small salt particles flowing out of the salt dissolving pipe can enter the mixing tank. (3) The connection between the connecting hose and the mixing tank is located at the bottom of the mixing tank. The sodium chloride solution from the salt tank enters from the bottom of the mixing tank and exits from the top of the mixing tank. This not only prolongs the residence time of the sodium chloride solution in the mixing tank, allowing the sodium chloride solution to fully contact the small salt particles, but also prevents the small salt particles from entering the sodium chlorate generator. (4) The collection pipe at the bottom of the mixing tank can temporarily store water-insoluble impurity particles in the connecting pipes and discharge them through the drain valve at the bottom. At the same time, the drain valve can also discharge an appropriate amount of small salt particles when they accumulate excessively in the mixing tank, thus maintaining the normal function of the mixing tank.

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.

[0019] 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.

[0020] As attached Figure 1-3 As shown, a sodium chloride solution concentration maintenance structure includes a salt replenishment mechanism 4, a connecting pipeline, and a stirring mechanism 6. The two ends of the connecting pipeline are respectively connected to a sodium hypochlorite generator 1 and a salt tank 2. The salt tank 2 supplies sodium chloride solution to the sodium hypochlorite generator 1 through the connecting pipeline. Both the salt replenishment mechanism 4 and the stirring mechanism 6 are located on the connecting pipeline.

[0021] Both the sodium hypochlorite generator 1 and the salt tank 2 are existing technologies. The sodium hypochlorite generator 1 is equipped with a salt supply pipe 11. After the salt supply pipe 11 is connected to the salt tank 2, when the sodium hypochlorite generator 1 needs sodium chloride solution, the valve inside the sodium hypochlorite generator 1 is opened, and the sodium chloride solution enters the sodium hypochlorite generator 1 through the salt supply pipe 11.

[0022] The salt tank 2 is a cylindrical or vertically arranged cuboid structure. The side wall of the salt tank 2 is provided with an inlet pipe 21 and an outlet pipe 22, and the salt tank 2 is connected to both the inlet pipe 21 and the outlet pipe 22.

[0023] The inlet pipe 21 is used to replenish water into the salt tank 2, and its connection point with the salt tank 2 is near the top of the salt tank 2. When the liquid level in the salt tank 2 is lower than the set position, the inlet pipe 21 replenishes water into the salt tank 2. The outlet pipe 22 is connected to the salt tank 2 near the lower middle part of the salt tank 2, and the outlet pipe 22 is used to send the sodium chloride solution in the salt tank 2 into the sodium hypochlorite generator 1.

[0024] A control valve 3 is installed at the end of the water outlet pipe 22 away from the salt tank 2, and other downstream pipes are connected through the control valve 3.

[0025] The salt replenishment mechanism 4 includes a salt replenishment pipe 41, an installation pipe 42, a salt dissolving pipe 43, and a salt tank 44.

[0026] The salt replenishment pipe 41 is horizontally installed on the connecting pipeline, located downstream of and connected to the control valve 3. Above the salt replenishment pipe 41, there is an installation pipe 42 that is perpendicular to and fixed to the salt replenishment pipe 41. The inner wall of the installation pipe 42 is threaded, and the bottom of the installation pipe 42 is connected to the salt dissolving pipe 43.

[0027] The salt dissolving tube 43 is a cylindrical thin tube closed at the bottom, extending vertically into the salt replenishment tube 41. The top of the salt dissolving tube 43 is connected to the installation tube 42, and several small holes are evenly distributed on the side wall of the salt dissolving tube 43.

[0028] The salt container 44 is a cylindrical, transparent storage tank that stores granular salt. The diameter of the salt granules is slightly larger than the diameter of the small holes on the side wall of the salt dissolving tube 43. A mounting head 441, communicating with the salt container 44, is located at the bottom of the salt container 44. The outer wall of the mounting head 441 is threaded. The length of the mounting head 441 is less than the length of the mounting tube 42, allowing the mounting head 441 to be inserted into the mounting tube 42 and threadedly engaged with it.

[0029] After the salt container 44 is installed in the installation pipe 42, the salt particles inside the salt container 44 naturally enter the installation pipe 42 and then the salt dissolving pipe 43 under the action of gravity. Under the dissolving and flushing effect of the sodium chloride solution flowing in the salt replenishment pipe 41, some of the salt particles completely dissolve, while others dissolve to a size smaller than the diameter of the small holes on the side wall of the salt dissolving pipe 43 and flow out of the salt dissolving pipe 43. At this time, the salt particles in the salt container 44 automatically fall into the salt dissolving pipe 43.

[0030] In this embodiment, the top of the salt container 44 is also provided with a sealing cover 442 that can open and seal the salt container 44. Salt can be added to the salt container 44 by opening the sealing cover 442.

[0031] The salt container 44 is made of a transparent material, such as glass or transparent plastic. The transparent salt container 44 allows for a clear view of the remaining amount of salt particles, enabling timely replacement or replenishment. When replacing or replenishing the salt container 44, the control valve 3 must be temporarily closed to prevent the sodium chloride solution in the salt tank 2 from overflowing from the mounting pipe 42.

[0032] The stirring mechanism 6 is located downstream of the salt replenishment mechanism 4. The stirring mechanism 6 includes a stirring tank 61, a motor 62, a paddle 63, a collection pipe 64, and a drain valve 65.

[0033] A connecting hose 5 is provided between the stirring mechanism 6 and the salt replenishment mechanism 4, with both ends of the connecting hose 5 connected to the salt replenishment pipe 41 and the stirring tank 61, respectively. Furthermore, the height of the connection point between the connecting hose 5 and the salt replenishment pipe 41 is higher than the connection point between the connecting hose 5 and the stirring tank 61, so that the small salt particles flowing out of the salt dissolving pipe 43 can smoothly enter the stirring tank 61 under the influence of the sodium chloride solution within the connecting hose 5.

[0034] The mixing tank 61 is a cylindrical or rectangular sealed cylinder that is vertically connected to the connecting pipeline.

[0035] The impeller 63 is located inside and at the bottom of the mixing tank 61, while the motor 62 is fixed above the mixing tank 61 by a bracket (not shown). The motor 62 and the impeller 63 are connected by a vertically extending stirring shaft inside the mixing tank 61. The stirring shaft is located on the central axis of the mixing tank 61, enabling the motor 62 to drive the impeller 63 to rotate. The sodium hypochlorite generator 1 has an internal controller; by connecting the control circuit of the motor 62 to the sodium hypochlorite generator 1, the motor 62 can be made to rotate only when the sodium hypochlorite generator 1 requires salt supply.

[0036] The stirred tank 61 is simultaneously connected to the connecting hose 5 and the salt supply pipe 11 of the sodium hypochlorite generator 1. The connection point between the connecting hose 5 and the stirred tank 61 is located at the bottom of the stirred tank 61, while the connection point between the salt supply pipe 11 and the stirred tank 61 is located at the top of the stirred tank 61. The sodium chloride solution enters from the bottom of the stirred tank 61 and exits from the top, allowing for sufficient contact with the small salt particles in the stirred tank 61. Furthermore, the natural downward deposition of the small salt particles in the stirred tank 61 prevents them from entering the sodium hypochlorite generator 1 through the salt supply pipe 11.

[0037] The bottom of the mixing jar 61 is designed to be sloping downwards and protruding, which allows the bottom of the mixing jar 61 to hold more small salt particles.

[0038] A collection pipe 64 is vertically positioned at the center of the bottom of the mixing tank 61 and is connected to the mixing tank 61. A drain valve 65 is located at the bottom of the collection pipe 64 and is connected to the collection pipe 64. The collection pipe 64 can temporarily store water-insoluble impurity particles deposited at the bottom of the mixing tank 61 and periodically discharge them through the drain valve 65 at the bottom.

[0039] In addition, the drain valve 65 can also be opened when excessive salt particles accumulate in the mixing tank 61, thereby discharging an appropriate amount of salt particles and maintaining the normal function of the mixing tank 61.

[0040] The implementation principle of the above embodiments is as follows: In this invention, the outlet pipe 22, control valve 3, salt replenishment pipe 41, connecting hose 5, stirring tank 61, and salt supply pipe 11 are sequentially connected to form a connecting pipeline. When the sodium hypochlorite generator 1 needs salt supply, the sodium chloride solution in the salt tank 2 enters the sodium hypochlorite generator 1 along the aforementioned path. At the salt replenishment pipe 41, the salt particles in the salt tank 44 naturally fall into the dissolving pipe 43. If the sodium chloride solution is saturated, the salt particles in the dissolving pipe 43 will not dissolve even though they come into contact with the flowing sodium chloride solution in the salt replenishment pipe 41. If the sodium chloride solution is unsaturated, the salt particles in the dissolving pipe 43 can dissolve to increase the concentration of the sodium chloride solution. At the same time, driven by the flowing sodium chloride solution, a small amount of incompletely dissolved salt particles will flow out from the small holes on the dissolving pipe 43 and, driven by the sodium chloride solution, enter the bottom of the stirring tank 61 along the connecting hose 5. Motor 62 drives blade 63 to rotate in stirring tank 61. If the sodium chloride solution is still not saturated, the small salt particles accumulated at the bottom of stirring tank 61 can be quickly dissolved, thereby rapidly increasing the concentration of sodium chloride solution to saturation, ensuring that the sodium hypochlorite generator 1 is always supplied with saturated sodium chloride solution.

[0041] 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.
