Description

Technical Field

[0001] The utility model relates to the technical field of melt crystallization, and more specifically to a novel melt crystallization device. Background Art

[0002] Melt crystallization is a novel chemical separation technology, which is widely used in the refining and purification of chemical intermediates, pharmaceutical intermediates, and biochemical products. It is mainly divided into two different processes: suspension crystallization method and layer crystallization.

[0003] In a novel melt crystallization device with the publication number CN219333218U, it is proposed that in the existing melt crystallization device during use, a sieve plate is arranged in the box body to separate crystal particles from solid and liquid. However, the sieve plate is easily blocked by crystal particles during use. At the same time, when the solution is discharged from the box body, the inner wall of the box body will still have residual solution, resulting in waste. By starting the motor to drive the rotation of the rotating shaft, the rotating shaft drives the gear to rotate, the gear drives the internal gear ring, the fixed rod, and the rotating rod to rotate, and the rotating rod drives the brush rod to rotate, and the brush rod cleans the sieve plate to prevent the sieve plate from being blocked by crystals.

[0004] In the above device, the upper part of the sieve plate is cleaned by the rotating brush rod. However, during the process of pushing the crystals to move, some crystals with a size similar to the sieve holes on the sieve plate will fall into the sieve holes, and the blockage of the sieve holes by the crystals will also affect the solid-liquid separation. Summary of the Utility Model

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a novel melt crystallization device to solve the problems existing in the above background art.

[0006] The utility model provides the following technical solution: A novel melt crystallization device includes a box body. The inner wall of the box body is fixedly connected with a sieve plate. The upper surface of the sieve plate is provided with a rotating hole. The inner wall of the rotating hole is rotatably connected with a rotating rod. The surface of the rotating rod is fixedly connected with a brush plate and a mounting strip respectively through a connecting mechanism. The brush plate is located above the sieve plate, and the mounting strip is located below the sieve plate. The upper surface of the sieve plate is provided with sieve holes. The upper surface of the mounting strip is provided with mounting holes. The inner wall of the mounting hole is fixedly connected with a sleeve. The inner wall of the sleeve is slidably connected with a sliding block. The opposite surfaces of the sliding block and the sleeve are fixedly connected with a return spring. One side of the sliding block away from the return spring is fixedly connected with a push rod. The top end of the push rod is fixedly connected with a hemispherical push block. The hemispherical push block is located inside the sieve hole;

[0007] A box door is installed on the surface of the box body. The position of the box door corresponds to the position of the sieve plate. The lower surface of the box body is fixedly connected with a driving motor. The output end of the driving motor extends into the box body and is fixedly connected with the bottom end of the rotating rod.

[0008] The further scheme is that the connecting mechanism includes a concave connecting box fixedly installed on the surface of the rotating rod. Connecting blocks are fixedly connected to the surfaces of the brush plate and the mounting strip. The connecting blocks are lapped with the inner wall of the concave connecting box. T-shaped grooves are formed in the front and back surfaces of the connecting blocks. Sliders are slidably connected to the inner walls of the T-shaped grooves. Connecting springs are fixedly connected to the opposite surfaces of the sliders and the T-shaped grooves. A positioning block is fixedly connected to the side of the slider away from the connecting spring. Both sides of the positioning block are arc-shaped. Positioning grooves adapted to the positioning block are formed in the inner front wall and the inner rear wall of the concave connecting box. The surface of the positioning block is lapped with the inner wall of the positioning groove.

[0009] The further scheme is that a connecting strip is fixedly connected to the surface of the rotating rod. A scraping plate is fixedly connected to the side of the connecting strip away from the rotating rod. The surface of the scraping plate is lapped with the inner wall of the box body. The side of the scraping plate facing the box body is conical. A feed pipe is installed on the upper surface of the box body. A drain pipe is installed on the lower surface of the box body. A valve is installed on the surface of the drain pipe.

[0010] The technical effects and advantages of the present utility model are as follows:

[0011] 1. In this new type of melt crystallization device, the setting of the sieve plate can separate solids from liquids. The crystals will be collected above the sieve plate. Start the driving motor to drive the rotating rod to drive the brush plate and the mounting strip to rotate. The rotation of the brush plate can push the crystals to accumulate in one place, preventing the crystals from covering the entire sieve plate and blocking the sieve holes. At the same time, when the mounting strip rotates, the arc surface of the hemispherical push block is stressed to push the push rod downward, and the return spring is compressed. When the hemispherical push block moves to other sieve holes, the elastic force of the return spring pushes the push rod to push the hemispherical push block into the sieve hole, which can push the crystals stuck in the sieve hole above the sieve plate, thus preventing the blockage of the sieve holes and ensuring the screening of solid-liquid separation of the crystals.

[0012] 2. In this new type of melt crystallization device, open the box door to facilitate the removal of the crystals on the sieve plate. And pull the brush plate or the mounting strip. At this time, the arc surface of the positioning block is stressed and received in the T-shaped groove, and the connecting block can be directly pulled out of the concave connecting box. Insert the connecting block into the concave connecting box, and the arc surface of the positioning block is also stressed and received. When the positioning block moves to the positioning groove, the elastic force of the connecting spring pushes the positioning block into the positioning groove, which is convenient for the replacement of the brush plate and the mounting strip.

Detailed implementation manners

[0019] A new type of melt crystallization device, referring to Figures 1-5 , includes a box body 1. A feed pipe is installed on the upper surface of the box body 1, a drain pipe is installed on the lower surface of the box body 1, a valve is installed on the surface of the drain pipe, a sieve plate 2 is fixedly connected to the inner wall of the box body 1, a rotating hole is opened on the upper surface of the sieve plate 2, and a rotating rod 3 is rotatably connected to the inner wall of the rotating hole. The surface of the rotating rod 3 is fixedly connected with a brush plate 4 and a mounting strip 5 respectively through a connecting mechanism.

[0020] The connecting mechanism includes a concave connecting box 13 fixedly installed on the surface of the rotating rod 3. Connecting blocks 14 are fixedly connected to the surfaces of the brush plate 4 and the mounting strip 5. The connecting blocks 14 are lapped with the inner wall of the concave connecting box 13. T-shaped grooves are opened on the front and back surfaces of the connecting blocks 14. Sliders 15 are slidably connected to the inner walls of the T-shaped grooves. Connecting springs 16 are fixedly connected to the opposite surfaces of the sliders 15 and the T-shaped grooves. A positioning block 17 is fixedly connected to one side of the slider 15 away from the connecting spring 16. Both sides of the positioning block 17 are arc-shaped. Positioning grooves adapted to the positioning block 17 are opened on the inner front wall and inner rear wall of the concave connecting box 13. The surface of the positioning block 17 is lapped with the inner wall of the positioning groove.

[0021] The brush plate 4 is located above the sieve plate 2, the mounting strip 5 is located below the sieve plate 2. Sieve holes are opened on the upper surface of the sieve plate 2. Mounting holes are opened on the upper surface of the mounting strip 5. A sleeve 6 is fixedly connected to the inner wall of the mounting hole. A sliding block 7 is slidably connected to the inner wall of the sleeve 6. A return spring 8 is fixedly connected to the opposite surfaces of the sliding block 7 and the sleeve 6. A push rod 9 is fixedly connected to one side of the sliding block 7 away from the return spring 8. A hemispherical push block 10 is fixedly connected to the top end of the push rod 9. The hemispherical push block 10 is located inside the sieve hole. A box door 11 is installed on the surface of the box body 1. The position of the box door 11 corresponds to the position of the sieve plate 2.

[0022] Open the box door 11 to facilitate the removal of the crystals on the sieve plate 2. Then pull the brush plate 4 or the mounting strip 5. At this time, the arc surface of the positioning block 17 is stressed and received in the T-shaped groove, and the connecting block 14 can be directly pulled out from the concave connecting box 13. Insert the connecting block 14 into the concave connecting box 13, and the arc surface of the positioning block 17 is also stressed and received. When the positioning block 17 moves to the positioning groove, the elastic force of the connecting spring 16 pushes the positioning block 17 into the positioning groove, which facilitates the replacement of the brush plate 4 and the mounting strip 5.

[0023] The lower surface of the box body 1 is fixedly connected with a driving motor 12. The output end of the driving motor 12 extends into the interior of the box body 1 and is fixedly connected to the bottom end of the rotating rod 3. The surface of the rotating rod 3 is fixedly connected with a connecting strip 18. The side of the connecting strip 18 away from the rotating rod 3 is fixedly connected with a scraping plate 19.

Start the driving motor 12 to drive the rotating rod 3 to drive the brush plate 4 and the mounting strip 5 to rotate. The rotation of the brush plate 4 can push the crystals to accumulate in one place, preventing the crystals from covering the entire sieve plate 2 and blocking the sieve holes. At the same time, when the mounting strip 5 rotates, the arc surface of the hemispherical push block 10 is stressed to push the push rod 9 downward, and the return spring 8 is compressed. When the hemispherical push block 10 moves to other sieve holes, the elastic force of the return spring 8 pushes the push rod 9 to push the hemispherical push block 10 into the sieve hole, which can push the crystals stuck in the sieve hole above the sieve plate 2, thus avoiding the blockage of the sieve holes and ensuring the screening of solid-liquid separation of the crystals.
