Description

Technical Field

[0001] The utility model belongs to the technical field of chemical processing equipment, in particular to a material filtering device for preparing fine chemicals. Background Art

[0002] The term "fine chemicals" has been used for a long time and originally refers to chemical products with small output, high purity and high price, such as medicines, dyes, coatings, etc. Existing fine chemicals often need to use filtering devices to assist production during preparation. In order to reduce the splash of liquid during the centrifugal filtration of raw materials when filtering the fine chemicals produced, it is usually adopted to add a cover to make the device as a whole closed. Although the cover reduces the splash of raw materials during the production of fine chemicals, the surface of the filter plate used for filtration cannot be cleaned regularly, so that the mesh of the impurities in the filtered chemicals will be blocked, thereby reducing the filtration efficiency of the device.

[0003] After searching, for example (authorization announcement number CN219965205U) a material filtering device for preparing fine chemicals, including a fine chemical filter box, the top of the fine chemical filter box is externally movably sleeved with a top cover, the bottom of the top cover is fixedly connected with a sealing block, the bottom of the fine chemical filter box is movably sleeved with a rotating shaft, the bottom end of the rotating shaft is fixedly connected with a rotating motor, and the top of the rotating shaft is fixedly connected with an external filter. This device solves the problem that the device cannot be closed centrifugally filtered when the existing equipment is used. However, although the existing device adopts a closed type for centrifugal filtration, it cannot clean the mesh inside the device. Because the production of chemical products often consumes a lot of time, the mesh cannot be cleaned, which will cause the mesh to be blocked and reduce the filtering efficiency of the device.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a material filtering device for fine chemical preparation, comprising a box body for providing assistance in the production of fine chemicals, two filter plates for filtering raw materials for fine chemical production are symmetrically arranged on the inner wall of the box body, two linear motors are arranged on opposite sides of the filter plates, a connecting plate is fixed to the moving parts of the two linear motors, a brush plate for easy cleaning is detachably connected to the side of the connecting plate close to the filter plate, and the brush plate is slidably connected to the filter plate;

[0006] Two symmetrical through slots are arranged on the top of the box body, and covers for easy opening and closing are movably connected to the tops of the two through slots. Handles for easy application are arranged on opposite sides of the two covers, and the covers are hinged to the top of the box body through hinges.

[0007] As a preferred embodiment, a transparent window is provided on the side of the box body for easy observation during the filtration of the fine chemical raw materials, and the transparent window is embedded in the interior of the box body.

[0008] As a preferred embodiment, two identical connecting pipes are staggeredly arranged on both sides of the box body, and meters are provided on the outer sides of the two connecting pipes for accurate measurement.

[0010] As a preferred embodiment, a spiral blade is welded on the outer peripheral side of the rotating shaft for stirring the chemical raw materials, and the blade is in contact with the inner bottom wall of the box.

[0011] As a preferred embodiment, the inner bottom wall of the box body is provided with two spatially symmetrical material troughs with complementary tilt angles. The bottoms of the material troughs are connected to the waste pipes arranged through the side walls of the box body, and the outside of the waste pipes is provided with valves for easy control.

[0012] As a preferred embodiment, one of the waste pipes is located below the transparent window.

[0013] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0014] The material filtering device for fine chemical preparation has two filter plates symmetrically arranged on the inner wall of a box body for filtering raw materials for fine chemical preparation, two linear motors are relatively symmetrically arranged on the two filter plates, a connecting plate is fixed to the moving part of the linear motor, a brush plate is detachably connected to the side of the connecting plate close to the filter plate, the brush plate is slidably connected to the filter plate, and chemical impurities blocked inside the mesh of the filter plate are cleaned to avoid long-term use, and a high filtering level can be always maintained, thereby improving the filtering efficiency of the device.

[0015] The material filtering device for fine chemical preparation usually requires stirring when the chemical is produced, which can not only speed up the filtration efficiency of the liquid, but also effectively prevent the precipitation of substances inside the chemical liquid, resulting in a reduction in the content of raw materials that may be used for fine chemical production, thereby improving the practicality of the device;

[0016] Connecting pipes for discharging production raw materials and waste pipes for cleaning waste are arranged on both sides of the box body. Under the action of the meter and control valve arranged on the surface, the overall sealing of the box body structure is completed, which is convenient for use.

[0017] The device solves the problem that the existing equipment cannot clean the mesh for filtering raw materials used for the preparation of fine chemicals when used.

[0026] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model.

[0027] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside in the figures shown in the present utility model, and are explained here together.

[0028] The connection method can be bonding, welding, bolt connection, etc., depending on actual needs.

[0029] Example

[0030] like Figures 1 to 5 As shown, because the linear motor 13 works in a chemical liquid environment for a long time and is used to stir the liquid for preparing fine chemicals, the linear motor 13, the connecting plate 9 and the brush plate 14 are treated with anti-corrosion, and are inspected and replaced through two symmetrically arranged cover plates 5 on the top of the box body 1 to maintain the normal use of the device.

[0031] This embodiment includes:

[0032] A box 1 is provided for providing assistance in the production of fine chemicals. Four supporting legs are welded at the bottom of the box 1. The arrangement of the supporting legs can ensure that good ventilation is always maintained around the box 1. Two filter plates 11 for filtering raw materials for fine chemical production are symmetrically arranged on the inner wall of the box 1. Two linear motors 13 are arranged on opposite sides of the filter plates 11 (that is, two linear motors 13 are arranged on the side of each filter plate 11 away from the inner wall of the box 1). A connecting plate 9 is fixed between the moving parts of the two linear motors 13. By controlling the lifting and lowering of the moving part of the linear motor 13, the position of the fixed connecting plate 9 is driven to move, thereby facilitating control.

[0033] The moving parts of the two linear motors 13 are fixed with a connecting plate 9. A brush plate 14 for easy cleaning is detachably connected to one side of the connecting plate 9 close to the filter plate 11. The brush plate 14 is slidably connected to the filter plate 11. The movement of the moving part of the linear motor 13 can control the movement of the brush plate 14 detachably connected to the connecting plate 9 to complete the cleaning of the mesh of the filter plate 11 (because chemical preparation, especially the preparation of fine chemicals, often has problems of long time, slow speed and low output). Therefore, if the mesh of the filter plate 11 cannot be cleaned in time after being used for a long time, the filtering capacity of the filter plate 11 will be reduced, further slowing down the filtering efficiency of the device, thereby reducing the preparation speed of fine chemicals.

[0034] A transparent window 2 is embedded in the side of the box body 1 for convenient observation during filtration of chemical raw materials. A waste pipe 8 with a control valve is provided below the transparent window 2. Another waste pipe 8 is provided on the other side of the box body 1 symmetrical to the transparent window 2. The waste pipe 8 is convenient for cleaning the waste filtered from the chemical raw materials. Staggered connecting pipes 3 are provided on both sides of the box body 1. A meter 4 for driving metering is provided on the outer side of the connecting pipe 3. The meter 4 is convenient for recording the filtration quality of the chemical liquid and facilitating the estimation of the quality during the preparation of fine chemicals.

[0035] Because two material troughs with complementary inclination angles in two spaces are provided on the inner bottom wall of the box body 1 (complementary, that is, the sum of the inclination angles is equal to one hundred and eighty degrees), the lowest points of the two material troughs are connected to the connecting pipe 3. In order to facilitate the cleaning of the filtered waste, a connecting port for the waste pipe 8 is provided on one side of the linear motor 13, and under the action of the through groove 12 set on the top of the box body 1, auxiliary cleaning is completed to improve the practicability of the device.

[0036] Two symmetrical through grooves 12 are provided on the top of the box body 1, and the tops of the two through grooves 12 are movably connected with cover plates 5 for easy opening and closing. Handles 6 for easy application are provided on the opposite sides of the two cover plates 5, and the cover plates 5 are hinged to the top of the box body 1 through hinges, and a driving motor 7 connected by screws is provided in the middle of the two cover plates 5. The output shaft of the driving motor 7 passes through the top wall of the box body 1 and is connected to one end of the rotating shaft 10. The other end of the rotating shaft 10 is rotatably connected to the inner bottom wall of the box body 1. A propeller-like blade 15 is welded on the outer side wall of the rotating shaft 10. The rotating shaft 10 is driven by the driving motor 7 to rotate, and the chemical agent liquid to be filtered inside the box body 1 is stirred, which can not only speed up the filtration efficiency, but also avoid the precipitation of substances inside the liquid, reduce the content of raw materials used in the production of fine chemicals, and improve the practicability of the device.

[0037] The meter 4, drive motor 7 and linear motor 13 are all conventional instruments. Their working principles, sizes and models are irrelevant to the functions of the present application, so they will not be described in detail. The control method of the present invention is controlled by a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0038] How it works

[0039] The material filtering device for preparing fine chemicals opens two symmetrically arranged cover plates 5 by means of a handle 6 under the hinged action of a hinge, places the chemical agent liquid required for filtering and separation into the interior of the housing 1, and closes the cover plate 5; then, controls the output shaft of the driving motor 7 to rotate, drives the connected rotating shaft 10 to rotate inside the housing 1, drives the paddles 15 welded to the outer wall of the rotating shaft 10 to rotate, and completes the stirring of the liquid; further, under the action of two symmetrical filter plates 11 arranged in the housing 1, completes the filtering of the raw materials for preparing fine chemicals, and in this process, regularly controls the movement of the moving part of the linear motor 13 to drive the movement of the fixed connecting plate 9, so that the brush plate 14 slidably connected to the filter plate 11 reciprocates to clean the impurities blocked in the mesh; finally, through the meter 4, completes the collection and aggregation of the filtered raw materials.
