Description

Technical Field

[0001] This utility model relates to the field of fine chemical technology, specifically a separation device for fine chemical production. Background Technology

[0002] Fine chemicals are a highly integrated and technology-intensive industry. The production process of fine chemicals involves a variety of chemical raw materials and includes multiple processes, such as multi-step synthesis, separation technology, analysis and testing, compounding technology, and formulation development. Separation technology requires the use of separation devices to separate various chemical raw materials.

[0003] Patent CN 221693115 U discloses a separation device for fine chemical production, including a main unit.

[0004] The device has an inlet at the top and an outlet at the front. A through groove is formed at the top, and a filter membrane frame is slidably connected inside the groove. A filter membrane body is installed inside the filter membrane frame. A housing is fixedly connected to the top of the filter membrane frame. Through holes are formed at both the front and rear ends of the housing. A fixing rod is slidably connected to the inner diameter of each through hole. By pulling the control block upwards, the control rod moves the U-shaped block upwards. The U-shaped block then drives the connecting rod, causing the fixing rod to move towards a closer side and disengage inside the fixing hole, thus releasing the filter membrane frame from its position. This allows the user to easily remove the filter membrane frame from inside the device and replace any worn-out filter membrane bodies.

[0005] However, replacing the filter membrane often requires the equipment to be shut down, which will affect the equipment's working efficiency in practical applications. Utility Model Content

The water suction pipe is located on one side of the servo motor and is parallel to the stirring rod in the cavity inside the filter box. The water suction pipe has through holes in the cavity inside the filter box. Multiple sets of through holes are provided on the side wall of the water suction pipe. It is worth noting that the cleaning device in this embodiment is existing conventional technology and will not be described in detail here.

[0011] Furthermore, the inner wall of the recessed groove of the filter box is fixedly installed with a box sealing gasket. By setting the box sealing gasket, the gap at the contact point between the filter box and the filter frame is sealed, reducing the possibility of unfiltered liquid passing through the gap.

[0012] Furthermore, filter plate sealing gaskets are fixedly installed on the inner walls of the grooves of the filter frame.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: As Figures 1-6 As shown, this utility model provides a separation device for fine chemical production, including a filter box 1 with an open top surface. The filter box 1 has an injection pipe 13 and a drain pipe 14 on its front and rear sides, respectively. The injection pipe 13 is connected to the rear wall of the filter box 1 via a flange, and the drain pipe 14 is connected to the front wall of the filter box 1 via flanges. The filter box 1 has a recessed groove near the center of its inner cavity, with two sets of recessed grooves symmetrically arranged within the cavity. A filter frame 3 is mounted on the recessed groove and is fitted inside it. A fixed rack 12 is mounted on the top of the filter frame 3, and a gear 7 is engaged with the teeth of the rack 12. A servo motor 2 is mounted above the gear 7, and the output port of the servo motor 2 is fixedly connected to the gear 7 via a drive shaft. A slide rail 10 is mounted on the side of the servo motor 2 away from the fixed rack 12, and a dovetail groove is formed on the surface of the slide rail 10. The dovetail groove is arranged facing the toothed edge of the fixed rack 12. A slider 11 is provided inside the dovetail groove, and the tail surface of the slider 11 is fixedly welded to the side wall of the servo motor 2. A rectangular slot is opened between the slide rail 10 and the fixed rack 12. A stirring rod 8 is provided inside the filter box 1 on the side of the gear 7 away from the servo motor 2. The top of the stirring rod 8 is fixedly connected to the bottom central shaft of the gear 7. A brush 801 is provided on the outer wall of the stirring rod 8, and multiple sets of brushes 801 are provided on the upper and lower outer wall of the stirring rod 8. The top of the filter frame 3 is fixed with the rack 12 and both sides of the slide rail 10, and a filter plate 5 is provided on the inner wall of the groove 301. The filter plate 5 is movably connected to the groove 301 by sliding up and down. Multiple sets of filter plates 5 are provided on the filter frame 3. A filter screen 4 is fixedly installed inside each filter plate 5. A handle pull ring 6 is provided on the top of the filter plate 5, and the handle pull ring 6 is fixedly welded to the top of the filter plate 5.

[0026] Working principle: In use, filter plates 5 are inserted into the inner wall of groove 301. Two sets of filter plates 5 are mounted on the filter frame 3, with a servo motor 2 positioned between them. A stirring rod 8 is connected below the servo motor 2, and a brush 801 is mounted on the side wall of the stirring rod 8. The motor 2's power output drives the stirring rod 8 and brush 801 to rotate. Liquid is then injected into the filter box 1 through the injection port 13 on the rear side wall. When the injected liquid contacts the nearest filter plate 5, it passes through the filter screen on the filter plate 5. 4. Filtration is performed. The filtered liquid is further filtered when it passes through the second filter plate 5 to improve the filtration effect. When viscous liquid accumulates in the connecting frame 3, the viscous liquid is stirred by the rotating stirring rod 8. Under the vibration of the stirring rod 8, the liquid is quickly filtered through the filter screen 4 of the filter plate 5 and enters the filter box 1. With multiple sets of filter plates 5, when the filter screen 4 is old and needs to be replaced, the filter plate 5 can be replaced directly without stopping the equipment or closing the liquid injection pipe 13, which greatly increases the efficiency of fine chemical production.

[0027] Example 2: Figures 1-5 As shown, this utility model provides a separation device for fine chemical production, including a filter box 1 with a cleaning device 9 on one side. The top of the cleaning device 9 has a connecting pipe 903, the opening of which communicates with the interior of the cleaning device 9. The other end of the connecting pipe 903 has a corrugated pipe 902 with a telescopic function. The other end of the corrugated pipe 902, away from the connecting pipe 903, has a suction pipe 901, the opening of which is fixedly connected to the opening of the corrugated pipe 902. The end of the suction pipe 901 away from the corrugated pipe 902 penetrates the side wall of the slider 11. The suction pipe 901 extends into the filter box 1 through the side wall of the slider 11. The suction pipe 901 is located on one side of the servo motor 2 and is parallel to the stirring rod 8 in the cavity inside the filter box 1. The suction pipe 901 has through holes in the cavity inside the filter box 1, and multiple sets of through holes are provided on the side wall of the suction pipe 901. It is worth noting that the cleaning device 9 in this embodiment is a conventional technology and will not be described in detail here.

[0028] The inner wall of the recessed groove of the filter box 1 is fixedly installed with a box sealing gasket to seal the gap between the recessed groove and the filter frame 3. The inner wall of the groove 301 of the filter frame 3 is fixedly installed with a filter plate sealing gasket. The gap at the contact point between the filter plate 5 and the filter frame 3 is sealed by the setting of the filter plate sealing gasket.

[0029] Working principle: When in use, when the stirring rod 8 stirs and vibrates the liquid, the filter impurities attached to the filter screen 4 fall off. The cleaning device 9 is activated. The connecting pipe 903 connected to the top generates suction through the suction pipe 901, which sucks the fallen impurities into the cleaning device 9. This increases the service life of the filter screen 4 and also improves the separation efficiency.
