Description

Technical Field

[0001] This utility model relates to the field of brine purification technology, and in particular to a brine purification device that facilitates filter replacement. Background Technology

[0002] In the salt processing process, especially the refining of fine salt, the main process is to purify coarse salt to obtain refined fine salt. Fine salt has the characteristics of uniform particle size and small particle size. A large amount of coarse salt solution is generated during the refining process. The coarse salt solution contains a large amount of salt. At the same time, there are also precipitated coarse salt particles in the salt solution. Therefore, it is necessary to filter the salt solution to remove impurities.

[0003] Common brine purification equipment only includes filtration, which can remove coarse salt particles precipitated from the brine. However, it lacks the function of conveniently replacing the filter screen, which cannot guarantee the convenience of filter screen replacement. The filter screen is often fixed to the housing with bolts, which makes the operation of replacing the filter screen very cumbersome and affects the purification efficiency.

[0004] Therefore, in view of the problem that the above-mentioned brine purification equipment lacks a convenient filter replacement function, which easily leads to filter clogging and time-consuming disassembly, thus restricting the continuous operation of the equipment, there is an urgent need to design a new type of brine purification equipment with easy filter replacement. Utility Model Content

[0005] To overcome the problem that common brine purification equipment lacks convenient filter replacement function, which easily leads to time-consuming disassembly after filter clogging, thus restricting the continuous operation of the equipment.

[0006] The technical solution of this utility model is as follows: a brine purification device for easy filter replacement, including a purification box; it also includes an upper motor, an upper rotating shaft, an upper arc plate, an upper filter frame, an upper filter screen, a lower motor, a lower rotating shaft, a lower arc plate, a lower filter frame, a lower filter screen, an upper limit bar, and a lower limit bar. The upper motor is located above the center of the front side of the purification box. The output end of the upper motor passes through the purification box and is connected to the upper rotating shaft. The rear end of the upper rotating shaft is rotatably connected to the rear side inside the purification box. The upper arc plate is fixed to the left side of the upper rotating shaft by bolts. An upper arc plate is located on the left side of the upper arc plate. The filter frame has an upper filter screen inside. A lower motor is located at the lower center of the front side of the impurity removal box. The output end of the lower motor passes through the impurity removal box and is connected to a lower rotating shaft.

Two upper limit bars are set on the left and right sides inside the impurity removal box corresponding to the positions of the upper filter frame. Two lower limit bars are set on the left and right sides inside the impurity removal box corresponding to the positions of the lower filter frame.

[0007] Preferably, when the filter screen needs to be replaced, the lower motor drives the lower rotating shaft to rotate in the opposite direction. The lower rotating shaft drives the lower filter frame to rotate in the opposite direction through the lower arc plate until the lower filter frame drives the lower filter screen to rotate from the right side of the impurity removal box to the left side. Then, the upper motor drives the upper rotating shaft to rotate in the opposite direction. The upper rotating shaft drives the upper filter frame to rotate in the opposite direction through the upper arc plate until the upper filter frame drives the upper filter screen to rotate from the left side of the impurity removal box to the right side. This completes the function of replacing the filter screen. This addresses the problem that common brine impurity removal equipment only has the function of filtration and can remove coarse salt particles precipitated from the brine, but lacks the function of convenient filter screen replacement. It cannot guarantee the convenience of filter screen replacement, and the filter screen is often fixed to the box with bolts, which makes the operation of replacing the filter screen very cumbersome and affects the impurity removal efficiency.

[0011] Preferably, two symmetrical sliding grooves are provided on the right side of the front side of the impurity removal box, and a cylinder is provided on the left side of the front side of the impurity removal box corresponding to the positions of the two sliding grooves.

[0013] Preferably, the rear end of the connecting rod passes through the groove and is placed inside the impurity removal box, and a brush is provided on the top of the connecting rod.

[0014] The beneficial effects of this utility model are:

[0015] 1. When replacing the filter screen, the lower motor drives the lower rotating shaft to rotate in the opposite direction, causing the lower arc plate and lower filter frame to rotate from the right side to the left side inside the impurity removal box. Then, the upper motor drives the upper rotating shaft in the opposite direction to drive the upper arc plate and upper filter frame, synchronously transferring the upper filter screen from the left side to the right side, realizing the screen replacement function of alternating operation of the two filters.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5This utility model provides an embodiment of a brine purification device with easy-to-replace filter screen, including a purification box 1; it also includes an upper motor 2, an upper rotating shaft 3, an upper arc plate 4, an upper filter frame 5, an upper filter screen 6, a lower motor 7, a lower rotating shaft 8, a lower arc plate 9, a lower filter frame 10, a lower filter screen 11, an upper limit bar 12, and a lower limit bar 13. The upper motor 2 is located above the middle of the front side of the purification box 1. The output end of the upper motor 2 passes through the purification box 1 and is connected to the upper rotating shaft 3. The rear end of the upper rotating shaft 3 is rotatably connected to the rear side inside the purification box 1. An upper arc plate 4 is bolted to the left side of the rotating shaft 3. An upper filter frame 5 is installed on the left side of the upper arc plate 4, and an upper filter screen 6 is installed inside the upper filter frame 5. A lower motor 7 is installed at the lower center of the front side of the impurity removal box 1. The output end of the lower motor 7 passes through the impurity removal box 1 and is connected to a lower rotating shaft 8. The rear end of the lower rotating shaft 8 is rotatably connected to the rear side inside the impurity removal box 1. A lower arc plate 9 is bolted to the left side of the lower rotating shaft 8. A lower filter frame 10 is installed on the left side of the lower arc plate 9, and a lower filter screen 11 is installed inside the lower filter frame 10. Two upper limit bars 12 are set on the left and right sides inside the impurity removal box 1, corresponding to the position of the upper filter frame 5. Two lower limit bars 13 are set on the left and right sides inside the impurity removal box 1, corresponding to the position of the lower filter frame 10. When the filter screen needs to be replaced, the lower motor 7 drives the lower rotating shaft 8 to rotate in the opposite direction. The lower rotating shaft 8 drives the lower filter frame 10 to rotate in the opposite direction through the lower arc plate 9, until the lower filter frame 10 drives the lower filter screen 11 to rotate from the right side inside the impurity removal box 1 to the left side inside the impurity removal box 1. Then the upper motor 2 drives the upper rotating shaft 3 to rotate in the opposite direction. The upper rotating shaft 3 drives the upper arc plate 9 to rotate in the opposite direction. Plate 4 drives the upper filter frame 5 to rotate in the opposite direction until the upper filter frame 5 drives the upper filter screen 6 to rotate from the left side inside the impurity removal box 1 to the right side inside the impurity removal box 1. This completes the function of replacing the screen. This solves the problem that common brine impurity removal equipment only has the function of filtration and can remove coarse salt particles precipitated in brine, but lacks the function of convenient screen replacement. It cannot guarantee the convenience of screen replacement. The screen is often fixed to the box with bolts, which makes the operation of screen replacement very cumbersome and affects the impurity removal efficiency.

[0024] Please see Figures 2-5In this embodiment, four support legs 14 are provided at the four corners of the bottom of the impurity removal box 1. A cleaning door 15 is movably connected to the bottom right side of the impurity removal box 1 via a hinge. By opening the cleaning door 15, the coarse salt particles filtered at the bottom of the impurity removal box 1 can be taken out. A partition plate 16 is provided in the middle of the bottom of the impurity removal box 1. Two triangular guide blocks 17 are symmetrically arranged on the right side of the bottom of the impurity removal box 1. Several drain pipes 18 are arranged at equal intervals on the left side of the bottom of the impurity removal box 1. After the salt solution is filtered, it falls to the bottom of the impurity removal box 1. At this time, the salt solution flows towards the drain pipes 18 through the guide blocks 17. The salt solution is discharged into the designated storage tank through the drain pipes 18. A top plate 19 is provided on the top of the impurity removal box 1. Several inlets 20 are opened at equal intervals on the top of the top plate 19 corresponding to the position of the drain pipes 18. The unfiltered salt solution is added into the interior of the impurity removal box 1 through the inlets 20.

[0025] Please see Figures 1-5 In this embodiment, two symmetrical sliding grooves 21 are provided on the right side of the front side of the impurity removal box 1. A cylinder 22 is provided on the left side of the front side of the impurity removal box 1 corresponding to the position of the two sliding grooves 21. When the upper filter frame 5 rotates from the left side of the impurity removal box 1 to the right side of the impurity removal box 1, the cylinder 22 is activated. The output end of the cylinder 22 is connected to a drive bar 23. The upper and lower ends of the drive bar 23 are provided with two connecting rods 24 corresponding to the positions of the two sliding grooves 21. The cylinder 22 drives the drive bar 23 to move back and forth left and right. The drive bar 23 drives the two connecting rods 24 to move back and forth left and right along the two sliding grooves 21. The rear end of the connecting rod 24 passes through the sliding groove 21 and is placed inside the impurity removal box 1. A brush 25 is provided on the top of the connecting rod 24. While the connecting rod 24 moves back and forth left and right, the brush 25 brushes off the coarse salt particles on the upper filter screen 6. The coarse salt particles fall down to the bottom of the impurity removal box 1.

[0026] During operation, the upper motor 2 drives the upper rotating shaft 3 to rotate in the forward direction. The upper rotating shaft 3 drives the upper filter frame 5 to rotate via the upper arc plate 4 until the upper filter frame 5 drives the upper filter screen 6 to rotate to the left side inside the impurity removal box 1. At this time, the upper filter frame 5 is supported by the upper limit bar 12. Meanwhile, the lower motor 7 drives the lower rotating shaft 8 to rotate in the forward direction. The lower rotating shaft 8 drives the lower filter frame 10 to rotate via the lower arc plate 9 until the lower filter frame 10 drives the lower filter screen 11 to rotate to the right side inside the impurity removal box 1. At this time, the lower limit bar 13 supports the lower filter frame 10. With zero support, the unfiltered brine is added into the impurity removal tank 1 through the inlet 20. As the brine falls, it is filtered through the upper filter screen 6, leaving coarse salt particles on top. The brine then falls to the bottom of the impurity removal tank 1, where it is guided by the triangular guide block 17 towards the drain pipe 18. The brine is then discharged into a designated storage tank through the drain pipe 18. When the filter screen needs to be replaced, the lower motor 7 drives the lower rotating shaft 8 to rotate in the opposite direction. The lower rotating shaft 8 drives the lower filter frame 10 to rotate in the opposite direction via the lower arc plate 9, until the lower filter frame 10 drives the lower filter screen 11 to rotate from the right side inside the impurity removal box 1 to the left side inside the impurity removal box 1. Then, the upper motor 2 drives the upper rotating shaft 3 to rotate in the opposite direction, and the upper rotating shaft 3 drives the upper filter frame 5 to rotate in the opposite direction via the upper arc plate 4, until the upper filter frame 5 drives the upper filter screen 6 to rotate from the left side inside the impurity removal box 1 to the right side inside the impurity removal box 1. This completes the function of replacing the filter screen. When the upper filter frame 5 rotates from the left side inside the impurity removal box 1... After rotating to the right side inside the impurity removal box 1, the cylinder 22 is activated. The cylinder 22 drives the drive bar 23 to move back and forth left and right. The drive bar 23 drives the two connecting rods 24 to move back and forth left and right along the two sliding grooves 21. While the connecting rods 24 move back and forth left and right, the brush 25 brushes off the coarse salt particles on the upper filter screen 6. The coarse salt particles fall down to the bottom of the impurity removal box 1. By opening the cleaning door 15, the filtered coarse salt particles at the bottom of the impurity removal box 1 can be removed, realizing the function of convenient filter screen replacement.

[0027] Through the above steps, when the filter screen needs to be replaced, the lower motor 7 drives the lower rotating shaft 8 to rotate in the opposite direction. The lower rotating shaft 8 drives the lower filter frame 10 to rotate in the opposite direction through the lower arc plate 9 until the lower filter frame 10 drives the lower filter screen 11 to rotate from the right side inside the impurity removal box 1 to the left side inside the impurity removal box 1. Then, the upper motor 2 drives the upper rotating shaft 3 to rotate in the opposite direction. The upper rotating shaft 3 drives the upper filter frame 5 to rotate in the opposite direction through the upper arc plate 4 until the upper filter frame 5 drives the upper filter screen 6 to rotate from the left side inside the impurity removal box 1 to the right side inside the impurity removal box 1. This completes the function of replacing the filter screen, which solves the problem that common brine impurity removal equipment only has the function of filtration and can remove coarse salt particles precipitated in brine, but lacks the function of convenient filter screen replacement. It cannot guarantee the convenience of filter screen replacement, and the filter screen is easily fixed to the box with bolts, which makes the operation of replacing the filter screen very cumbersome and affects the impurity removal efficiency.
