Description

Technical Field

[0001] This utility model relates to the technical field of brine preparation equipment, and in particular to a salt dissolving device for a semi-dry salt tank. Background Technology

[0002] Online sodium hypochlorite generators require a large amount of salt for production. However, traditional high-water-level salt tanks have insufficient salt storage capacity, necessitating frequent salt replenishment during use. This is particularly problematic in wastewater treatment, where salt consumption is measured in tons, making frequent replenishment extremely costly and increasing operational risks. While low-water-level semi-dry salt tanks significantly increase salt storage capacity, the salt at the bottom of the tank tends to clump and clog the drain pipes, making salt retrieval extremely difficult.

[0003] Therefore, in view of the shortcomings of the existing technology, it is necessary to design a salt dissolving device for a semi-dry salt tank to solve the above problems.

[0004] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solution of this utility model and facilitating the understanding of those skilled in the art. It should not be assumed that the above content is known to those skilled in the art simply because it has been described in the background section of this utility model. Utility Model Content

[0005] To overcome the shortcomings of the prior art, the present invention aims to disclose a salt dissolving device for a semi-dry salt storage tank, which solves the problem of difficulty in dissolving and extracting solid salt in a semi-dry salt storage tank.

[0006] This utility model discloses a salt dissolving device for a semi-dry salt silo, comprising a semi-dry salt silo and a salt dissolving pool. A salt discharge pipe is provided on the bottom side wall of the semi-dry salt silo to allow solid salt at the bottom of the silo to be discharged preferentially, preventing long-term accumulation of solid salt at the bottom. The outer end of the salt discharge pipe is connected to the inlet of a suction pump, and the outlet of the suction pump is connected to the salt dissolving pool via a pipe. The suction of the suction pump overcomes the resistance of solid salt being discharged from the salt silo. A first valve is provided on the salt discharge pipe to control the connection between the semi-dry salt silo and the suction pump. A second valve is installed on the pipeline between the pump and the salt dissolving tank to control the connection between the suction pump and the salt dissolving tank. The salt dissolving tank is connected to a soft water inlet pipe, a flow aid pipe, and a concentrated brine outlet pipe. The soft water inlet pipe is used to provide soft water for the preparation of concentrated brine in the salt dissolving tank, and the concentrated brine outlet pipe is used to transport the prepared concentrated brine to the outside. The outer end of the flow aid pipe is connected to the inlet of the flow aid pump, which draws brine from the salt dissolving tank, pressurizes it, and then transports it through the pipeline to the two ends before and after the first valve to promote the outward transport of solid salt in the semi-dry salt bin.

[0007] Preferred technical solution: A third valve is provided at the outlet of the flow-aiding pump to control the connection and disconnection between the flow-aiding pipe and the salt discharge pipe.

[0008] Preferred technical solution: A booster pump is connected to the concentrated brine output pipe to control the delivery of concentrated brine from the salt dissolving tank.

[0009] Preferred technical solution: A fourth valve is installed on the concentrated brine output pipe between the booster pump and the brine dissolving tank to control the connection between the brine dissolving tank and the booster pump.

[0010] Preferred technical solution: The first valve, the second valve, the third valve and the fourth valve are all electric valves, which facilitates automatic control.

[0011] Preferred technical solution: The soft water inlet pipe is controlled to open and close by a float valve installed in the salt dissolving tank to ensure the stability of the liquid level in the salt dissolving tank.

[0012] Preferred technical solution: The salt dissolving tank is equipped with a level gauge and a stirring device to ensure that the concentration of brine reaches saturation while accelerating the dissolution of solid salt.

[0013] Preferred technical solution: The diameter of the salt discharge pipe is between DN40 and DN100. Within this range, the resistance encountered by solid salt in the salt discharge pipe is moderate, and it will not flow out of the salt tank uncontrollably due to gravity caused by the height of the salt tank. At the same time, the resistance can be overcome by the suction pump.

[0014] Preferred technical solution: The concentrated brine output pipe is also equipped with a filter to filter out impurities in the concentrated brine.

[0015] Due to the application of the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows:

[0016] This invention discloses a salt dissolving device for a semi-dry salt tank. A suction pump directly transports solid salt from the semi-dry salt tank to a dissolving pool. A flow-assisted pump draws brine from the dissolving pool, pressurizes it, and then transports it through a discharge pipe. The brine reduces friction between solid salt particles and between the particles and the sidewalls of the transport pipe, making it easier to transport solid salt from the semi-dry salt tank to the dissolving pool. The flow-assisted pump is connected to both ends of a first valve via pipes. Even when the first valve is closed, the flow-assisted pump can still supply brine to the semi-dry salt tank, preventing solid salt from caking at the bottom of the tank. It also flushes the suction pump and its connecting pipes, preventing solid salt accumulation. A float valve controls the replenishment of soft water in the dissolving pool, achieving automatic liquid level balance. The diameter of the discharge pipe controls the range of output resistance of solid salt in the semi-dry salt tank. The device is simple, ingenious, and low-cost. Attached Figure Description

[0026] Example:

[0027] like Figure 1 As shown, this utility model discloses a salt dissolving device for a semi-dry salt tank, including a semi-dry salt tank 1 and a salt dissolving pool 2. The main components of the present utility model will be described in detail below:

[0028] like Figure 1 As shown, the bottom side wall of the semi-dry salt tank 1 is equipped with a salt discharge pipe 3, which allows the solid salt at the bottom to be discharged first, realizing the first-in-first-out principle for solid salt and avoiding long-term stagnation of solid salt at the bottom of the semi-dry salt tank 1, which would cause caking. The outer end of the salt discharge pipe 3 is connected to the inlet of the suction pump 4, and the outlet of the suction pump 4 is connected to the salt dissolving tank 2 through a pipe. The suction force of the suction pump 4 is used to extract solid salt from the semi-dry salt tank 1 and transport it to the salt dissolving tank 2. The salt discharge pipe 3 is equipped with a first valve 5, which is used to control the connection between the salt discharge pipe 3 and the suction pump. The pipe between the suction pump 4 and the salt dissolving tank 2 is equipped with a second valve 6, which is used to control the connection between the suction pump 4 and the salt dissolving tank 2. The salt dissolving tank 2 is connected to a soft water inlet pipe 7, a flow aid pipe 8, and a concentrated brine outlet pipe 9. The outer end of the flow aid pipe 8 is connected to the inlet of the flow aid pump 10, and the outlet of the flow aid pump 10 is connected to the front and rear ends of the first valve 5 through pipes, respectively, for transporting pressurized brine.

[0029] The method and principle of this utility model are as follows: When solid salt needs to be taken, the first valve 5 and the second valve 6 are opened, and the suction pump 4 is started to draw the solid salt from the bottom of the semi-dry salt bin 1 into the salt dissolving tank 2 through the salt discharge pipe 3. During this process, the flow aid pump 10 draws out the brine in the salt dissolving tank 2 through the flow aid pipe 8, pressurizes it, and then transports it to the salt discharge pipe 3. The pressurized brine is transported through the salt discharge pipe 3 to both the semi-dry salt bin 1 and the salt dissolving tank 2. After entering the semi-dry salt bin 1, the pressurized brine dissolves the caking solid salt, allowing it to flow out from the salt discharge pipe 3. The brine in the salt discharge pipe 3 fills the gaps between the solid salt and the pipe wall, as well as between the solid salt particles, reducing the transport resistance of the solid salt and thus improving the transport efficiency and stability of the solid salt. When the salt content in the salt dissolving tank 2 reaches the standard, the first valve 5 is closed, and the pressurized brine provided by the flow aid pump 10 flushes the brine in the suction pump 4 and its pipes into the salt dissolving tank 2, preventing solid salt from depositing and caking in the pipes and causing blockages.

[0030] like Figure 1 As shown, a third valve 11 is provided at the outlet of the flow-assisted pump 10 to prevent backflow.

[0031] like Figure 1 As shown, in order to facilitate the control of the concentrated brine delivery rate, a booster pump 12 is connected to the concentrated brine output pipe 9.

[0032] like Figure 1 As shown, in order to facilitate the control of the outflow of concentrated brine, a fourth valve 13 is provided on the concentrated brine output pipe 9 between the booster pump 12 and the salt dissolving tank 2.

[0033] like Figure 1 As shown, to facilitate automated control, the first valve 5, the second valve 6, the third valve 11, and the fourth valve 13 are all electric valves.

[0034] like Figure 1 As shown, in order to maintain the automatic balance of the liquid level in the salt dissolving tank, the soft water inlet pipe 7 is controlled to open and close by a float valve 14 installed in the salt dissolving tank 2.

[0035] like Figure 1 As shown, in order to ensure the brine concentration and mixing efficiency, the salt dissolving tank 2 is equipped with a level gauge 15 and a stirring device 16.

[0036] like Figure 1 As shown, in order to achieve large-volume high-level storage in the semi-dry salt bin, the diameter of the salt discharge pipe 3 is between DN40 and DN100. At this time, the flow resistance of solid salt in the salt discharge pipe 3 is moderate, and it will not flow out of the semi-dry salt bin 1 uncontrollably due to the gravity caused by the height of the semi-dry salt bin 1. At the same time, the resistance can be overcome by the suction pump 4.

[0037] like Figure 1As shown, in order to ensure the purity of the concentrated brine, a filter 17 is also provided on the concentrated brine output pipe 9.

[0038] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
