Description

Technical Field

[0001] The utility model belongs to the technical field of filtering devices, and particularly relates to a chemical raw material filtering device. Background Art

[0002] Chemical raw materials are raw materials produced by chemical methods, including inorganic chemical products other than fertilizers, inorganic coatings, inorganic pigments, etc., and various products made mainly from local molecular materials in the organic synthesis industry.

[0003] Chemical raw materials need to be screened. Due to the characteristics of some chemical raw materials, they are easy to agglomerate on the screen and block the mesh. If the agglomerated raw materials are always attached to the mesh, it is easy to cause corrosion and damage to the screen. Finally, the filtration efficiency can only be restored by replacing the filter. For this reason, we propose a chemical raw material filtration device to solve the above problem. Utility Model Content

[0004] The utility model provides a chemical raw material filtering device, which solves the problems in the prior art.

[0005] The technical solution of the utility model is achieved in this way:

[0006] A chemical raw material filtering device comprises a filter, a filter plate arranged at the filter outlet, and a lifting mechanism arranged along the side of the filter, wherein a dredging structure is fixedly mounted on the lifting mechanism for dredging the mesh of the filter plate;

[0007] The dredging structure includes a supporting plate and a movable plate that are movably connected to each other. A dredging guide column is fixedly arranged on the upper end surface of the movable plate corresponding to the mesh of the filter plate. The supporting plate can be rotated upward along the connection with the movable plate so that the dredging guide column is aligned with the mesh of the filter plate. The dredging guide column is driven up and down by the lifting mechanism to dredge the mesh of the filter plate.

[0008] Furthermore, the filter comprises a filter device body, a feed hopper integrally formed along the upper end of the filter device body, and vertical rods fixedly connected along the four corners of the filter device body.

[0009] Furthermore, the lifting mechanism includes a guide rail, on which a movable block is movably connected, and the dredging structure is fixedly mounted on the movable block to achieve up and down reciprocating motion.

[0010] Furthermore, a limiting member is provided between the bearing plate and the movable plate, and the limiting member enables the bearing plate and the movable plate to remain perpendicular or parallel to each other.

[0011] Furthermore, the limiting member includes a fixed plate fixedly mounted on the carrying plate, and a rotating plate fixedly mounted on the movable plate. An arc groove is provided along the inner side of the rotating plate, a movable column is movably engaged in the arc groove, and a groove with a radius smaller than the arc groove is also provided on the inner side of the movable column. When the groove is located in the arc groove, the rotating plate can rotate along the connection with the fixed plate. When the other parts of the movable column are located in the arc groove, the rotating plate and the fixed plate are stuck and cannot move.

[0012] Furthermore, the rotation limit range of the rotating plate is 0-90 degrees.

[0013] Furthermore, a spring is provided between one end of the movable column and the fixed plate, so as to reset the movable column in the absence of external force.

[0014] After adopting the above technical solution, the beneficial effects of the utility model are:

[0015] In the utility model, a dredging structure is provided. When the dredging structure is in use, the movable plate rotates upward and is perpendicular to the supporting plate, so that the dredging guide column on the movable plate is driven by the lifting mechanism to dredge the sieve holes on the filter plate, thereby preventing the sieve holes from being blocked and restoring the filtering efficiency. The dredging structure can be stored on the side of the filtering device at ordinary times without affecting the normal filtering of the filtering device. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example: Figure 1 As shown, a chemical raw material filtering device includes a filter, and the filter includes a filtering device body 10. A feed hopper 11 is integrally connected to the upper end of the filtering device body 10, and the feed hopper 11 is fed into the filtering device body 10. Vertical poles 12 are welded at the four corners of the filtering device body 10 to help the filtering device be supported on the ground. Figure 3 As shown, a filter plate 13 is also embedded inside the lower end of the filter device body 10. After the chemical raw materials are screened by the filter plate 13, qualified raw materials are screened out for processing;

[0024] Due to the characteristics of some chemical raw materials, such as polyvinyl alcohol particles, such raw materials are easy to agglomerate during storage or filtration, blocking the mesh of the filter plate 13, thereby reducing the filtration efficiency in the subsequent filtration process and possibly causing damage to the filter plate 13. Figure 1-2 As shown, a lifting mechanism is provided on the side of the filtering device body 10, and a dredging structure 30 is provided on the lifting mechanism to dredge the mesh of the filter plate 13. The lifting mechanism includes a guide rail 20, and a movable block 21 is movably provided along the guide rail 20. The dredging structure 30 is fixedly mounted on the movable block 21. After filtering several batches of raw materials, the dredging structure 30 can be used to dredge the mesh of the filter plate 13 to achieve the purpose of restoring the filtering efficiency.

[0025] Among them, Figure 1 As shown, the dredging structure 30 includes a bearing plate 301 fixedly mounted on the movable block 21, and a movable plate 302 is movably connected along the lower end of the bearing plate 301. A limit member 304 is arranged between the movable plate 302 and the bearing plate 301. The limit member 304 is a 90-degree limit member, and its rotation angle is manually adjusted, such as Figure 1As shown, when it is needed, the movable plate 302 is manually rotated upward by 90 degrees so that the movable plate 302 and the carrying plate 301 are perpendicular to each other, and a dredging guide column 303 is also arranged along the upper end surface of the movable plate 302 and the mesh of the filter plate 13. After the movable plate 302 and the filter plate 13 are in a parallel relationship, the lifting mechanism is started to make the movable block 21 move up and down along the guide rail 20, and the movable plate 302 moves up and down with the movable block 21, and the mesh of the filter plate 13 is dredged by the dredging guide column 303 arranged on the movable plate 302 to prevent the mesh from being blocked by the raw material;

[0026] Afterwards Figure 2 As shown, after the dredging is completed, the movable plate 302 is manually rotated downward by 90 degrees, so that the movable plate 302 and the supporting plate 301 are parallel to each other, and the dredging structure 30 is driven by the movable block 21 to move up and reset, and is stored on the side of the filter device body 10, which is not easy to affect the filtering condition of the device;

[0027] In order to realize the limiting of the limiting member 304, Figure 4 As shown, the stopper 304 includes a fixed plate 304B fixedly mounted on the side wall of the carrier plate 301 close to the filter device body 10, and also includes a rotating plate 304A fixedly arranged on the side wall of the movable plate 302, the two are movably connected, an arc groove 304E is provided along the end surface of the rotating plate 304A, a movable column 304C is movably clamped in the arc groove 304E, a groove 304D with a radius smaller than the arc groove 304E is also provided on the inner side of the movable column 304C, and a spring is also provided between one end of the movable column 304C and the fixed plate 304B. Spring 304F, when the rotating plate 304A needs to move, pulls the movable column 304C to one side, so that the groove 304D opened on the inner side of the movable column 304C is located in the arc groove 304E. Since the radius of the groove 304D is smaller than the arc groove 304E, the rotating plate 304A can rotate. After the adjustment is completed, without the action of external force, the spring 304F pulls the interactive movable column 304C to reset and clamp the arc groove 304E to achieve limiting, so that the movable plate 302 and the supporting plate 301 are vertical or parallel, and will not rotate easily.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
