Description

Technical Field

[0001] This application relates to the field of salt treatment pond technology, and more particularly to a salt treatment pond. Background Technology

[0002] In the salt-making process, raw salt containing impurities needs to be dissolved in water to form brine. After stirring, filtering, precipitation, evaporation and other processes, high-purity refined salt is obtained. However, existing salt-making tanks need to be equipped with stirring devices to quickly stir, mix and dissolve the brine. This not only increases equipment costs, but also affects the brine dissolution efficiency if the stirring device malfunctions, which is not conducive to continuous production. Utility Model Content

[0004] To achieve the above objectives, this application provides a salt treatment tank, including a cylindrical salt treatment vessel connected to a filter tank. An inlet pipe is installed inside the salt treatment vessel, with the top of the inlet pipe extending out of the salt treatment vessel. Multiple distribution pipes arranged in a circular array are connected to the bottom of the inlet pipe. The openings of the multiple distribution pipes are arranged in a counterclockwise or clockwise direction, and the openings of the multiple distribution pipes are parallel to the tangential direction of the adjacent sidewall of the salt treatment vessel.

[0005] Optionally, the water distribution pipe includes a straight pipe section connected to the water inlet pipe, the straight pipe section is connected to a bend section, the bend section is connected to a reducer, and the diameter of the reducer gradually decreases in the direction away from the bend section.

[0006] Optionally, a three-way solenoid valve is connected to one end of the water inlet pipe extending out of the salt tank. The three-way solenoid valve is connected to a water supply pipe and an air supply pipe respectively.

[0007] Optionally, the three-way solenoid valve is electrically connected to a controller disposed on the outer wall of the salt tank, and the controller is electrically connected to a liquid level sensor disposed on the inner wall of the salt tank.

[0008] Optionally, the inner wall of the salt tank is provided with a first filter screen that communicates with the filtration pool, and the first filter screen is higher than the liquid level sensor.

[0009] Optionally, a cross-shaped baffle is provided inside the filtration tank to divide the filtration tank into a first transfer tank, a second transfer tank, a third transfer tank, and a fourth transfer tank. The first and second transfer tanks are both connected to the side wall of the salt dissolving tank. The second and third transfer tanks are arranged adjacent to each other. The first transfer tank is connected to the salt dissolving tank through a first filter screen. A second filter screen is provided between the first and second transfer tanks. A third filter screen is provided between the second and third transfer tanks. A fourth filter screen is provided between the third and fourth transfer tanks. The filtration accuracy of the first, second, third, and fourth filter screens increases sequentially.

[0010] Optionally, the heights of the first filter, second filter, third filter, and fourth filter decrease sequentially.

[0011] Optionally, the fourth transfer tank is connected to a drain pipe, which is located near the bottom of the fourth transfer tank and is a telescopic corrugated pipe.

[0012] The beneficial effects that this application can achieve are as follows:

[0013] This application includes a cylindrical salt dissolving tank connected to a filter tank. An inlet pipe extends out of the tank, and multiple distribution pipes arranged in a circular array are connected to its bottom. The outlets of these distribution pipes are arranged in a counter-clockwise or clockwise direction, and are parallel to the tangent of the adjacent sidewall of the salt dissolving tank. Based on this structure, after adding raw salt containing impurities to the salt dissolving tank, water is added through the inlet pipe. When the water flows out from the distribution pipes, the water flows tangentially to the salt dissolving tank and in the same counter-clockwise or clockwise direction, creating a swirling flow that promotes the fluidity of the brine and achieves a stirring effect. This eliminates the need for a separate stirring device, reducing equipment costs. Furthermore, the distribution pipe structure avoids the drawback of power failures preventing stirring. The dissolved brine then enters the filter tank for the next process. Attached Figure Description

[0025] Example

[0026] Reference Figures 1-3 This embodiment provides a salt treatment tank, including a cylindrical salt treatment tank 110. The salt treatment tank 110 is connected to a filter tank 210. An inlet pipe 120 is provided inside the salt treatment tank 110. The top of the inlet pipe 120 extends out of the salt treatment tank 110. The bottom of the inlet pipe 120 is connected to a plurality of water distribution pipes 130 arranged in a ring array. The openings of the plurality of water distribution pipes 130 are arranged in a counterclockwise or clockwise direction, and the openings of the plurality of water distribution pipes 130 are parallel to the tangent direction of the adjacent side wall of the salt treatment tank 110.

[0027] In this embodiment, after adding the raw salt containing impurities into the salt dissolving tank 110, water is added through the water inlet pipe 120. When the water is discharged from multiple water distribution pipes 130, since the water in the water distribution pipes 130 flows out tangentially to the salt dissolving tank 110 and flows out in the same counterclockwise or clockwise direction, the water flow is driven to form a certain vortex, which promotes the fluidity of the brine and forms a certain stirring effect. Thus, the stirring effect can be achieved without a stirring device, reducing equipment costs. Moreover, the stirring effect is achieved by using the water distribution pipe 130 structure, which avoids the disadvantage of not being able to stir due to power failure. The dissolved brine then enters the filter tank 210 for the next process.

[0028] As an optional implementation, the water distribution pipe 130 includes a straight pipe section 131 connected to the water inlet pipe 120, a bend pipe section 132 connected to the straight pipe section 131, and a reducer pipe 133 connected to the bend pipe section 132. The diameter of the reducer pipe 133 gradually decreases in the direction away from the bend pipe section 132.

[0029] In this embodiment, when water enters multiple water distribution pipes 130 from the inlet pipe 120, it flows sequentially through the straight pipe section 131, the bend pipe section 132, and the reducing pipe 133. Due to the reducing pipe 133's reducing structure, the water pressure when the water flows out can be increased, thereby promoting the formation of a swirling effect and improving the stirring effect.

[0030] As an optional implementation, the end of the water inlet pipe 120 extending out of the salt tank 110 is connected to a three-way solenoid valve 140. The three-way solenoid valve 140 is connected to a water supply pipe 150 and an air supply pipe 160 respectively. The water supply pipe 150 is used to connect to a water source, and the air supply pipe 160 is used to connect to an air supply device (such as an air compressor).

[0031] In this embodiment, the three-way solenoid valve 140 allows the water inlet pipe 120 to be connected to either the water supply pipe 150 or the air supply pipe 160. After adding a certain amount of water to the salt tank 110 via the water supply pipe 150, the three-way solenoid valve 140 closes the water supply pipe 150 and connects the air supply pipe 160. At this time, the water inlet pipe 120 no longer receives water, and the air supply pipe 160 can be supplied with gas through an air compressor or other air supply equipment. The gas enters the water inlet pipe 120 and is discharged from the water distribution pipe 130. The gas with a certain pressure enters the brine and further forms a swirling effect, while also forming bubbles, which further improves the stirring effect.

[0032] As an optional implementation, the three-way solenoid valve 140 is electrically connected to a controller 170 disposed on the outer wall of the salt tank 110, and the controller 170 is electrically connected to a liquid level sensor 180 disposed on the inner wall of the salt tank 110.

[0033] In this embodiment, the liquid level sensor 180 can sense that the salt tank 110 has been filled with water to a certain level and send a signal to the controller 170. The controller 170 then controls the three-way solenoid valve 140 to automatically switch the valve port to connect to the air supply pipe 160, so as to carry out the next step of introducing gas to improve the stirring effect, without the need for manual management.

[0034] It should be noted that after the salt dissolving tank 110 has been stirred by introducing gas for a certain period of time, all the brine in the salt dissolving tank 110 can be pumped to the filter tank 210 by setting up a water pump (not shown in the figure). This is suitable for the salt dissolving process of small or quantitative raw salt. The controller 170 can be a PLC controller of model S7-200, which meets the usage requirements.

[0035] As an optional implementation, the inner wall of the salt tank 110 is provided with a first filter screen 190 that communicates with the filter pool 210, and the first filter screen 190 is higher than the liquid level sensor 180.

[0036] In this embodiment, the salt dissolving tank 110 and the filter pool 210 are connected by the first filter screen 190, which can filter out impurities in the raw salt. At the same time, after the salt dissolving tank 110 is stirred by introducing gas for a certain period of time (the time threshold can be set by the controller 170), the controller 170 controls the three-way solenoid valve 140 to switch the valve port to connect to the water supply pipe 150 to continue adding water. At this time, the water level rises to the first filter screen 190 and flows into the filter pool 210. At this time, the water supply state can be maintained continuously, and raw salt can be added to the salt dissolving tank 110 intermittently, so it can be applied to the continuous salt dissolving process and the operation mode is flexible.

[0037] As an optional implementation, a cross-shaped partition 220 is provided inside the filter tank 210 to divide the filter tank 210 into a first transfer tank 230, a second transfer tank 240, a third transfer tank 250, and a fourth transfer tank 260. The first transfer tank 230 and the second transfer tank 240 are both connected to the side wall of the salt dissolving tank 110. The second transfer tank 240 and the third transfer tank 250 are arranged adjacent to each other. The first transfer tank 230 is connected to the salt dissolving tank 110 through a first filter screen 190. A second filter screen 270 is provided between the first transfer tank 230 and the second transfer tank 240. A third filter screen 280 is provided between the second transfer tank 240 and the third transfer tank 250. A fourth filter screen 290 is provided between the third transfer tank 250 and the fourth transfer tank 260. The filtration accuracy of the first filter screen 190, the second filter screen 270, the third filter screen 280, and the fourth filter screen 290 increases sequentially.

[0038] In this embodiment, the filtration tank 210 is divided into four independent areas by a cross-shaped partition 220: a first transfer tank 230, a second transfer tank 240, a third transfer tank 250, and a fourth transfer tank 260. When the brine in the salt tank 110 enters the first transfer tank 230 through the first filter screen 190, it undergoes the first filtration. Then, it enters the second transfer tank 240 through the second filter screen 270 for the second filtration. Then, it enters the third transfer tank 250 through the third filter screen 280 for the third filtration. Finally, it enters the fourth transfer tank 260 through the fourth filter screen 290 for the fourth filtration, thus increasing the filtration precision in sequence. This allows for the sequential filtration of impurities of different particle sizes in the brine, improving filtration accuracy and effectiveness while reducing the risk of clogging during a single filtration. Furthermore, the filtration tank 210 uses a four-grid arrangement, which saves more space compared to a linear arrangement.

[0039] As an alternative implementation, the heights of the first filter screen 190, the second filter screen 270, the third filter screen 280, and the fourth filter screen 290 decrease sequentially to prevent brine backflow.

[0040] As an optional implementation, the fourth transfer tank 260 is connected to a drain pipe 310. The drain pipe 310 is close to the bottom of the fourth transfer tank 260. Finally, the filtered brine is discharged through the drain pipe 310 to the next sedimentation tank for evaporation to produce refined salt. The drain pipe 310 is a telescopic corrugated pipe that can be extended and bent. When one sedimentation tank is full of brine, the telescopic corrugated pipe can be connected to another empty sedimentation tank, making it flexible to use.

[0041] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
