Description

Technical Field

[0001] This solution belongs to the field of industrial salt processing, specifically involving an industrial salt impurity separation device. Background Technology

[0002] Industrial salt is a basic raw material in the chemical industry, and its main components include sodium chloride and sodium nitrite. Industrial salt plays a vital role in the chemical industry; many basic chemical products, such as hydrochloric acid, caustic soda, soda ash, ammonium chloride, and chlorine, are produced using industrial salt as a raw material. In addition, industrial salt can also be used as a dyeing auxiliary in industries such as printing and dyeing, leather making, and textiles.

[0003] A search revealed a utility model patent application with authorization announcement number CN218637121U, which discloses a purification device for industrial salt production. The device includes a housing with a feed hopper installed through the top. Two sets of shock absorbers are symmetrically installed on the top wall of the housing's inner cavity, located on opposite sides of the feed hopper. Two sets of connecting plates are symmetrically installed at the bottom of the two sets of shock absorbers. A screen box is installed on the inner side of the two connecting plates. A vibrator is installed at the bottom of the connecting plates via a support frame. A screen plate is installed at an angle inside the screen box. This utility model, with its screen box, screen plate, shock absorbers, and vibrator, allows industrial salt requiring purification to enter the screen box's inner cavity. The screen plate filters larger particles of impurities in the industrial salt. The vibrator vibrates the screen box, and the shock absorbers, by suppressing the oscillations and impacts caused by the springs absorbing shock, improve the smoothness of the screen box. Together, these components ensure that the screen plate effectively filters the industrial salt, preventing larger particles from clogging the screen holes and guaranteeing efficient purification.

[0004] In existing technologies, adding a vibrator during the industrial salt screening process results in an excessively high vibration frequency. Even with the addition of a shock absorber, the entire device can easily resonate, leading to instability in the entire impurity removal device. Furthermore, the impurities mixed in industrial salt have varying particle sizes, making it difficult for a single sieve plate to completely separate the impurities from the industrial salt. Utility Model Content

[0005] The purpose of this solution is to provide an industrial salt impurity separation device to solve the problem that the vibrator easily causes instability of the entire device in the existing technology, and at the same time solve the problem of insufficient impurity separation.

[0006] To achieve the above objectives, this solution provides an industrial salt impurity separation device, including a separation tank with an open top. A top cover is installed at the bottom of the separation tank, and a feeding pipe is installed on one side of the top cover. A spline shaft is installed at the lower center of the top cover, with the top of the spline shaft penetrating the top cover and connected to a drive motor. The drive motor is fixed to the top cover. The spline shaft is rotatably connected to the top cover, and the bottom of the spline shaft is placed inside a spline sleeve. Several spaced-apart filter mechanisms are arranged on the spline sleeve. A push rod is provided at the bottom of the spline sleeve, penetrating the bottom of the separation tank and connected to it via a sliding bearing. A push plate is connected to the bottom of the push rod, and an eccentric wheel is provided below the push plate to push it. A drive mechanism is installed on the eccentric wheel.

[0007] The principle of this solution is as follows: During use, the drive mechanism drives the eccentric wheel to rotate below the push plate, thereby driving the push rod to reciprocate up and down at the bottom of the separation tank. This causes the spline sleeve to rotate and also reciprocate up and down on the spline shaft. As the industrial salt solution mixed with impurities is poured into the separation tank from the feed pipe, the industrial salt solution will pass through multiple filtration mechanisms to complete the filtration. The impurities in the industrial salt will be retained in the filtration mechanisms, thus achieving the separation of impurities from industrial salt.

[0008] The technical advantages of this solution are as follows: the continuous rotation of the filtration mechanism generates centrifugal force on the industrial salt solution, thereby increasing the force exerted when the industrial salt solution passes through the filtration mechanism and accelerating the filtration process. The multiple filtration mechanisms also ensure the adequacy of the industrial salt solution filtration. Furthermore, the continuous pushing of the push rod to push the spline sleeve on the spline shaft allows impurities to move freely on the filtration mechanism, preventing excessive impurities from clogging it.

[0009] Furthermore, at least three spaced-apart support legs are installed at the bottom edge of the separation tank, and a discharge pipe is installed on one side of the bottom of the separation tank. The discharge pipe is used to discharge the completely separated industrial salt solution.

[0010] Furthermore, each of the aforementioned filter mechanisms is equipped with a mounting base, which is fixed to a spline sleeve. Several spaced-apart fixing rods with their ends bent upwards into an "L" shape are mounted on the side of the mounting base. A filter screen is installed on the inner side of each fixing rod, with the bottom of the feed pipe corresponding to the inner side of the uppermost filter screen. Through multiple layers of filter screens, the industrial salt solution is filtered multiple times, and the L-shaped fixing rods ensure that the centrifuged industrial salt solution also makes full contact with the filter screens, guaranteeing the filtration effect.

[0011] Furthermore, the mesh size of the filter screens on each of the aforementioned filtration mechanisms increases sequentially from top to bottom, and the length of the fixing rods also increases sequentially. The bottom of the fixing rods is inclined downwards towards the spline sleeve. By using multiple filter screens with different mesh sizes, multi-stage filtration of the industrial salt solution is provided. The inclined fixing rods also make the bottom filter screens funnel-shaped, which helps the centrifugally applied industrial salt solution to have sufficient contact with the filter screens.

[0012] Furthermore, a buffer block, which is an elastic rubber block, is installed at the bottom of the spline sleeve. The buffer block cushions the contact between the push rod and the spline sleeve, preventing damage from excessive impact.

[0013] Furthermore, a compression spring is fitted at the bottom of the push rod. One end of the compression spring is fixed to the push plate, and the other end is fixed to the bottom of the separator. The compression spring limits the downward movement of the push rod without affecting its upward movement, ensuring the stabilizing effect of the eccentric wheel on the push plate.

[0014] Furthermore, the drive mechanism includes a drive shaft that is fixedly inserted through one end of the eccentric wheel. Both ends of the drive shaft are rotatably mounted on a fixed base, which is fixed to the separation tank. A second drive motor is mounted on one end of the drive shaft and is fixed to the fixed base. The operation of the second drive motor provides power for the rotation of the eccentric wheel.

[0021] The basic implementation examples are as follows: Figures 1-4 As shown: An industrial salt impurity separation device includes a separation tank 1, which is a tank with an open top. At least three spaced-apart support legs 3 are installed at the bottom edge of the separation tank 1. A discharge pipe 5 is installed on one side of the bottom of the separation tank 1, through which the completely separated industrial salt solution is discharged. A top cover 2 is installed at the bottom of the separation tank 1. A feeding pipe 4 is installed on one side of the top cover 2. A spline shaft 7 is installed in the lower middle part of the top cover 2. The top of the spline shaft 7 passes through the top cover 2 and is connected to a drive motor 6. The drive motor 6 is fixed on the top cover 2. The spline shaft 7 is rotatably connected to the top cover 2. The bottom of the spline shaft 7 is placed in a spline sleeve 8. Several spaced-apart filter mechanisms 9 are provided on the spline sleeve 8.

[0022] like Figure 1 , Figure 3 As shown, each filtration mechanism 9 is equipped with a mounting base 10, which is fixed to the spline sleeve 8. Several spaced-apart fixing rods 11 with their ends bent upwards into an "L" shape are installed on the side of the mounting base 10. Filter screens 12 are installed on the inner side of the fixing rods 11. The bottom of the feeding pipe 4 corresponds to the inner side of the uppermost filter screen 12. Through multiple layers of filter screens 12, the industrial salt solution is filtered multiple times. The L-shaped fixing rods 11 ensure that the centrifuged industrial salt solution is fully in contact with the filter screens 12, guaranteeing the filtration effect. The mesh size of the filter screens 12 on each filtration mechanism 9 increases sequentially from top to bottom, and the length of the fixing rods 11 also increases sequentially. The bottom of the fixing rods 11 is inclined downwards towards the spline sleeve 8. By using multiple filter screens 12 with different mesh sizes, multi-stage filtration of the industrial salt solution is provided. The inclined fixing rods 11 also make the bottom filter screens 12 funnel-shaped, which helps the centrifuged industrial salt solution to fully contact the filter screens 12.

[0023] like Figure 2 , Figure 3 , Figure 4As shown, the bottom of the spline sleeve 8 is provided with a push rod 14, the bottom of which penetrates the bottom of the separation tank 1, and the two are connected by a sliding bearing. The bottom of the push rod 14 is connected to a push plate 15, and below the push plate 15 is an eccentric wheel 17 that pushes the push plate 15. A drive mechanism 21 is mounted on the eccentric wheel 17. The drive mechanism 21 includes a drive shaft 18, which is fixedly inserted through one end of the eccentric wheel 17. Both ends of the drive shaft 18 are rotatably mounted on a fixed seat 19, which is fixed to the separation tank 1. A drive motor 20 is mounted on one end of the drive shaft 18, which is fixed to the fixed seat 19. The drive motor 20 is driven by a drive motor. The operation of motor 20 provides power for the rotation of eccentric wheel 17; a buffer block 13 is installed at the bottom of spline sleeve 8. The buffer block 13 is an elastic rubber block. The buffer block 13 buffers the contact between push rod 14 and spline sleeve 8 to prevent excessive collision and damage; a compression spring 16 is sleeved at the bottom of push rod 14. One end of the compression spring 16 is fixed to push plate 15, and the other end of the compression spring 16 is fixed to the bottom of separation tank 1. The compression spring 16 can limit the downward movement of push rod 14 without affecting the upward movement of push rod 14, thus ensuring the stability of eccentric wheel 17 on push plate 15.

[0024] The specific implementation process of this utility model is as follows: In use, the drive mechanism 21 drives the eccentric wheel 17 to rotate below the push plate 15, thereby driving the top rod 14 to reciprocate up and down at the bottom of the separation tank 1, thereby driving the spline sleeve 8 to rotate and also reciprocate up and down on the spline shaft 7. As the industrial salt solution mixed with impurities is poured into the separation tank 1 from the feed pipe 4, the industrial salt solution will pass through multiple filter mechanisms 9 to complete the filtration, while the impurities in the industrial salt will remain in the filter mechanism 9, realizing the separation of impurities from industrial salt.

[0025] This solution uses a continuously rotating filter mechanism 9 to generate centrifugal force on the industrial salt solution, thereby increasing the force acting on the industrial salt solution as it passes through the filter mechanism 9 and accelerating the filtration of the industrial salt solution. Multiple filter mechanisms 9 also ensure the adequacy of the filtration of the industrial salt solution. Furthermore, the push rod 14 continuously pushes the spline sleeve 8 to slide back and forth on the spline shaft 7, allowing impurities to move freely on the filter mechanism 9, preventing excessive impurities from clogging the filter mechanism 9.
