Description

Technical Field

[0001] The utility model relates to the technical field of solid salt treatment, in particular to a device for preventing solid salt from flowing back in an environment prone to scarring. Background Art

[0002] The calcium brine from the calcium production workshop, the return water from the filter press, and the brine from the tank workshop are spontaneously mixed in the recovery pool. The recovered water is then pumped into three salt barrels filled with solid granular salt through pipelines by a submersible pump. After countercurrent contact with the solid salt, it dissolves into saturated crude brine and flows by gravity to the crude brine storage tank for use in the next process.

[0003] In the process of realizing the utility model, the inventors found that there are at least the following problems in this technology: since the calcium ions contained in the calcium brine react with the carbonate ions in the filter press return water to form calcium carbonate, some calcium ions and carbonate ions that have not reacted completely enter the pipeline through the recovery pump. Under the high-speed stirring of the pump impeller, solid calcium carbonate scars are formed in the pipeline. The connection between the valve plate and the valve body of the check valve is not flexible due to the scarring. When the pump stops, the valve plate of the check valve does not return to its position, and the pipeline return water and the solid salt in the brine tank flow back into the submersible pump along the pipeline, which can easily block the pipeline, causing the system to fail to operate normally and making cleaning difficult. Utility Model Content

[0004] In order to improve the problem that the pipeline return water and the solid salt in the salt tank in the above-mentioned device flow back into the submersible pump along the pipeline, which easily blocks the pipeline, causing the system to not operate normally and is difficult to clean, the utility model provides a device to prevent the backflow of solid salt in an environment prone to scarring.

[0005] The utility model provides a device for preventing solid salt from flowing back in an environment prone to scarring, and adopts the following technical solutions:

[0006] A device for preventing solid salt from flowing back in an environment prone to scarring comprises a bottom plate, a recovery pool is installed at the left end of the top of the bottom plate, a salt-dissolving barrel is installed at the right end of the top of the bottom plate, a launch port is opened on the top of the salt-dissolving barrel, an upper end of the right side of the salt-dissolving barrel is connected with a water outlet pipe, a recovery pump is installed on the inner bottom wall of the recovery pool, a delivery pipe is connected between the output end of the recovery pump and the salt-dissolving barrel, a first check valve is provided at one end of the delivery pipe close to the recovery pump, a third check valve is provided at one end of the delivery pipe close to the salt-dissolving barrel, a short pipe is installed at one end of the delivery pipe close to the third check valve, and a frustum is installed inside the short pipe.

[0007] By adopting the above technical scheme, in the future, the calcium brine from the self-made calcium workshop, the return water from the filter press station and the brine from the tank workshop will be added to the inside of the recovery pool in sequence. After spontaneous mixing inside the recovery pool, the recovery pump will start to transport the recovered water to the inside of the salt-dissolving barrel through the hot water flushing pipe. After countercurrent contact with the solid salt inside the salt-dissolving barrel to dissolve into saturated crude brine, it will flow to the crude brine storage tank through the outlet pipe for use in the next process. When the first check valve and the third check valve fail due to scarring, the solid salt inside the salt-dissolving barrel will flow back. When it encounters the short pipe, part of the salt will be blocked in the cavity between the outer wall of the cone and the short pipe. Since the pipeline area inside the cone is increased, the left end of the cone will not be blocked. When the recovery pump is running again, the concentration of the recovered water is low, which can melt the loose solid salt.

[0008] Optionally, a liquid level sensor is installed at the lower end of the left side wall of the recovery tank inner cavity, and a controller is installed at the left end of the recovery tank. The output end of the liquid level sensor is electrically connected to the input end of the controller, and the output end of the controller is electrically connected to the input end of the recovery pump.

[0009] By adopting the above technical solution, the liquid level inside the recovery tank is sensed by a liquid level sensor. When the liquid level inside the recovery tank is lower than the position of the liquid level sensor, a signal is transmitted to the controller, and the controller turns off the recovery pump. When the liquid level inside the recovery tank is higher than the position of the liquid level sensor, a signal is transmitted to the controller, and the controller starts the recovery pump, thereby realizing automatic start and stop of the recovery pump.

[0010] Optionally, an observation window is installed on the surface of the salt tank.

[0011] By adopting the above technical solution, the staff can observe the amount of solid salt added into the salt tank through the observation window.

[0012] Optionally, second flanges are installed on both sides of the short tube, first flanges are installed on both ends of the delivery pipe close to the short tube, and a plurality of locking bolts are provided at the edges of the first flange and the second flange.

[0013] By adopting the above technical solution, it is convenient to fix the first flange and the second flange by means of locking bolts, thereby facilitating the installation of the short pipe on the conveying pipe.

[0014] Optionally, one end of the delivery pipe close to the short pipe is connected to a hot water flushing pipe, and a second check valve is provided on the hot water flushing pipe.

[0015] By adopting the above technical solution, hot water is transported to the inside of the short pipe through the hot water flushing pipe through the delivery pipe, and the hot water has a strong ability to dissolve salt.

[0016] Optionally, the frustum is horizontally placed inside the short tube, and the inner diameter of the left end of the frustum is greater than the inner diameter of the right end of the frustum.

[0017] By adopting the above technical solution, when solid salt refluxes and encounters the truncated cone, part of the salt is blocked in the cavity of the outer wall of the truncated cone. However, inside the truncated cone, since the pipeline area is increased by about 4 times, there will be no blockage at the truncated cone.

[0018] In summary, the present invention has at least one of the following beneficial effects:

[0019] By coordinating the recovery pump, the delivery pipe, the cone, the short pipe and the salt tank, when the first check valve and the third check valve fail, the delivery pipe can be modified to slow down or stop the backflow of solid salt and prevent pipeline blockage to ensure the normal operation of the system.

[0020] Through the coordinated arrangement of the second check valve and the hot water flushing pipe, hot water is added into the interior of the value delivery pipe through the hot water flushing pipe and transported to the interior of the short pipe, thereby dissolving the solid salt inside the short pipe, further slowing down or preventing the backflow of the solid salt, and improving the practicability of the device.

The output end of the liquid level sensor 1 is electrically connected to the input end of the controller, and the output end of the controller is electrically connected to the input end of the recovery pump 3. The liquid level inside the recovery tank 2 is sensed by the liquid level sensor 1. When the liquid level inside the recovery tank 2 is lower than the position of the liquid level sensor 1, the signal is transmitted to the controller, and the controller turns off the recovery pump 3. When the liquid level inside the recovery tank 2 is higher than the position of the liquid level sensor 1, the signal is transmitted to the controller, and the controller starts the recovery pump 3, so as to realize the automatic start and stop of the recovery pump 3.

[0028] Please refer to the attached figure in the instruction manual Figure 1 and Figure 2 A delivery pipe 6 is fixedly connected between the output end of the recovery pump 3 and the salt tank 15, a first check valve 4 is arranged at one end of the delivery pipe 6 close to the recovery pump 3, a third check valve 14 is arranged at one end of the delivery pipe 6 close to the salt tank 15, a short pipe 12 is installed at one end of the delivery pipe 6 close to the third check valve 14, a hot water flushing pipe 8 is connected to one end of the delivery pipe 6 close to the short pipe 12, and a second check valve 7 is arranged on the hot water flushing pipe 8.

[0029] Please refer to the attached figure in the instruction manual Figure 1 A truncated cone 11 is installed inside the short tube 12. The truncated cone 11 is horizontally placed inside the short tube 12. The inner diameter of the left end of the truncated cone 11 is larger than the inner diameter of the right end of the truncated cone 11. When the solid salt flows back and encounters the truncated cone 11, part of the salt is blocked in the cavity of the outer wall of the truncated cone 11.

[0030] Please refer to the attached figure in the instruction manual Figure 1 and Figure 2The second flanges 10 are fixedly mounted on both sides of the short tube 12, and the first flanges 9 are mounted on both ends of the delivery pipe 6 near the short tube 12.

[0031] Working principle: In the future, the calcium brine from the self-made calcium workshop, the return water from the filter press and the brine from the tank workshop will be added to the inside of the recovery pool 2 in sequence. After spontaneous mixing inside the recovery pool 2, the recovery pump 3 starts to transport the recovered water to the inside of the salt barrel 15 through the hot water flushing pipe 8. After countercurrent contact with the solid salt inside the salt barrel 15, it will be dissolved into saturated crude brine, and then flow to the crude brine storage tank through the outlet pipe 16 for use in the next process.

When the pipe 12 is connected, part of the salt is blocked in the cavity between the outer wall of the cone 11 and the short pipe 12. Since the pipeline area inside the cone 11 is increased, the cone 11 will not be blocked. When the recovery pump 3 is running again, the concentration of the recovered water is low, which can melt the loose solid salt. At the same time, the hot water flushing pipe 8 is connected to the front end of the short pipe 12, so that the hot water can be transported to the inside of the short pipe 12 through the delivery pipe 6 through the hot water flushing pipe 8. The hot water has a strong ability to dissolve salt, which can effectively solve the problem of pipeline blockage caused by failure of the first check valve 4 and the third check valve 14.
