[0001] This application relates to the field of salt production equipment technology, and more specifically, to a brine-salt-sand separation device. Background Technology

[0002] In the salt chemical industry and brine comprehensive utilization, brine salt-sand separation is a crucial and fundamental step. Brine is typically sourced from salt lakes, salt mines, or underground brine resources. Its composition is complex, containing not only salts such as sodium chloride but also a large amount of solid impurities such as sand and clay. During brine salt production, the presence of sand and other impurities severely affects the purity and quality of the salt product, reducing production efficiency. Furthermore, sand entering subsequent processing equipment accelerates equipment wear, increases maintenance costs and downtime, and reduces the stability and continuity of the production line. Therefore, it is necessary to propose a brine salt-sand separation device to solve these problems. Summary of the Invention

[0026] likeFigure 1 and Figure 2 As shown, this application provides a brine salt-sand separation device, including a separation box 1. The separation box 1 is divided into a pretreatment chamber 11 and a settling chamber 12 from top to bottom. The top of the separation box 1 is provided with an inlet 13 communicating with the pretreatment chamber. A buffer tank 2 is provided on one side of the separation box 1. The separation box 1 is provided with a first connecting port 14 for connecting the pretreatment chamber 11 and the buffer tank 2 and a second connecting port 15 for connecting the buffer tank 2 and the settling chamber 12. A filter plate 3 is installed in a pull-out manner at the first connecting port 14, which facilitates the disassembly or installation of the filter plate 3. When it is necessary to change to a different filter aperture, the filter plate 3 can be easily installed. The filter plate 3 is designed for easy replacement. The separation chamber 1 is equipped with a cleaning assembly 4 for cleaning the filter plate 3. The separation chamber 1 also has an overflow pipe 5 connected to the settling chamber 12. During use, brine enters the pretreatment chamber 11 from the inlet 13 at the top of the separation chamber 1. As the brine flows from the pretreatment chamber 11 to the buffer tank 2, the filter plate 3 filters out large particles of impurities in the brine, trapping them within the pretreatment chamber 11, thus initially separating the brine from the large particles. However, as filtration continues, a large amount of impurities accumulates on the filter plate 3, affecting the filtration effect and the quality of the brine. The cleaning component 4 can promptly remove impurities from the filter plate 3, ensuring its filtration performance and enabling the filtration process to continue efficiently. The filtered brine enters the buffer tank 2 through the first connecting port 14. The buffer tank 2 buffers the water flow, making the brine flow rate more stable. Then, the brine enters the settling chamber 12 through the second connecting port 15. In the settling chamber 12, remaining fine sand and other impurities gradually settle to the bottom under gravity, while the purer brine rises to the top. When a certain height is reached, the relatively pure brine in the upper layer will flow out of the separation box 1 through the overflow pipe 5, completing the entire salt-sand separation process. The brine-salt-sand separation device of this application achieves multi-stage separation through the preliminary filtration of the filter plate 3 and the further sedimentation of the settling chamber 12. The filter plate 3 can intercept large particles of impurities, while the settling chamber 12 can remove fine sand particles, thereby improving the effect of brine-salt-sand separation, improving the purity and quality of salt products, improving production efficiency, reducing the wear of sand particles on subsequent equipment, reducing maintenance costs and downtime for maintenance, and ensuring the stable and continuous operation of the production line.

[0027] like Figure 2As shown, the cleaning assembly 4 includes a fixed frame 41, a cleaning motor 42, a first bevel gear 43, a cleaning rod 44, a second bevel gear 45, a mounting bracket 46, and a cleaning brush 47. The fixed frame 41 is fixedly installed in the first connecting port 14. The cleaning rod 44 is rotatably mounted on the fixed frame 41. The cleaning brush 47 is fixedly installed on the cleaning rod 44, and the bristles of the cleaning brush 47 abut against the filter plate 3. The first bevel gear 43 is fixedly installed at the end of the cleaning rod 44 away from the cleaning brush 47. The cleaning motor 42 is fixedly installed on the mounting bracket 46 via the fixed frame 41. On the outer casing 1, the output shaft of the sweeping motor 42 extends into the first connecting port 14. The second bevel gear 45 is fixed on the output shaft of the sweeping motor 42 and meshes with the first bevel gear 43. Specifically, the first connecting port 14 is provided with a protective shell. The first bevel gear 43 and the second bevel gear 45 are located inside the protective casing 48. The output shaft of the sweeping motor 42 and the sweeping rod 44 are rotatably connected to the protective casing 48. Sealing rings are provided at the connection points of the output shaft of the sweeping motor 42, the sweeping rod 44 and the protective casing 48 (as shown in the figure). (Not shown), the protective box 48 can prevent impurities from affecting the meshing of the first bevel gear 43 and the second bevel gear 45, and reduce the wear of the first bevel gear 43 and the second bevel gear 45. When it is necessary to clean the filter plate 3, the cleaning motor 42 is started. The cleaning motor 42 drives the second bevel gear 45 to rotate. Since the first bevel gear 43 and the second bevel gear 45 are meshed, the rotation of the second bevel gear 45 will drive the first bevel gear 43 to rotate, which in turn causes the cleaning rod 44 to rotate around its own axis. When the cleaning rod 44 rotates, it drives the cleaning brush 47 to rotate and clean the surface of the filter plate 3, sweeping off the large particles of impurities intercepted on the filter plate 3, preventing impurities from clogging the pores of the filter plate 3, and ensuring the normal filtration function of the filter plate 3. Through the continuous cleaning of the filter plate 3 by the cleaning brush 47, the impurities accumulated on the filter plate 3 can be removed in time, avoiding the decrease in filtration efficiency due to impurity blockage, thereby ensuring that the filter plate 3 always maintains good filtration performance, so that the brine can pass through the filter plate 3 smoothly for preliminary separation.

[0028] like Figure 1 and Figure 2 As shown, a sludge discharge pipe 6 connected to the settling chamber 12 is provided on the lower side of the separation box 1. A sludge discharge valve 61 is provided on the sludge discharge pipe 6. When the accumulated silt, sand, impurities and other silt reach a certain amount, the sludge discharge valve 61 on the sludge discharge pipe 6 is opened. Under the action of the liquid pressure and gravity inside the settling chamber 12, the silt, sand, impurities and other silt at the bottom of the settling chamber 12 will be discharged from the separation box 1 through the sludge discharge pipe 6. After the sludge discharge is completed, the sludge discharge valve 61 is closed to prevent the brine from continuing to flow out, to ensure that the liquid level inside the settling chamber 12 is stable, and to maintain normal separation operation.

[0029] like Figure 2As shown, the settling chamber 12 is equipped with a ramp 7. The lower end of the ramp 7 is connected to the sludge discharge pipe 6. The ramp 7 can guide the sludge to flow to the sludge discharge pipe 6, avoid the sludge from being dispersed and accumulated at the bottom of the settling chamber 12, improve the efficiency and thoroughness of sludge discharge, reduce the residue of sludge in the settling chamber 12, and further ensure the effect of brine salt-sand separation.

[0030] like Figure 2 and Figure 3 As shown, a buffer baffle 8 is fixed at the second connecting port 15. The upper end of the buffer baffle 8 is provided with a toothed opening 81. When brine enters the settling chamber 12 from the buffer tank 2 through the second connecting port 15, the buffer baffle 8 will block and buffer the brine. Since the upper end of the buffer baffle 8 is provided with a toothed opening 81, the brine will flow down from the toothed opening 81 in a dispersed manner, instead of rushing directly into the settling chamber 12 with a large flow rate and impact force. This can slow down the speed of the brine entering the settling chamber 12 and disperse it into multiple streams. This avoids disturbing the already settled sand particles due to the excessive flow rate when the brine enters the settling chamber 12. This allows the brine to carry out the subsequent salt and sand separation process more smoothly in the settling chamber 12, thereby improving the effect of brine salt and sand separation. The brine obtained is purer and is conducive to improving the quality of subsequent salt products.

[0031] like Figure 1 As shown, a transparent observation window 9 is provided on one side of the settling chamber 12 on the separation box 1. Specifically, the transparent observation window 9 is usually made of a transparent and sturdy material, such as tempered glass. The operator can observe the working status inside the settling chamber 12 in real time through the transparent observation window 9 and understand the progress of brine salt-sand separation in a timely manner. For example, by observing the settling speed and accumulation of sand particles, the operator can judge whether the separation effect is good and whether it is necessary to open the sludge discharge valve 61 to discharge sludge.

[0032] like Figure 2 As shown, the lower end of the buffer tank 2 is connected to a sand discharge pipe 10, and a sand discharge valve 101 is provided on the sand discharge pipe 10. When it is necessary to clean the large sand particles filtered by the filter plate 3 in the pretreatment chamber 11, the filter plate 3 is removed, the sand discharge valve 101 on the sand discharge pipe 10 is opened, and under the action of gravity, the large sand particles in the pretreatment chamber 11 enter the buffer tank 2 and are then discharged from the sand discharge pipe 10.

[0033] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
