[0020] 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 in 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.

[0021] See also Figure 1 to Figure 3 In an embodiment of the utility model, a filtering device for preparing high-purity barium chloride includes a filter box 1 and a baffle 2 arranged on the top of the filter box 1, and support rods 7 with rectangular distribution are fixedly installed between the baffle 2 and the filter box 1. The baffle 2 is used to prevent debris from falling into the filter box 1.

[0022] The side wall of the filter box 1 is welded with supporting legs 8 distributed in a regular triangle to provide stable support for the filter box 1. One side of the supporting legs 8 is provided with a collecting box 9 located at the bottom of the filter box 1 to collect the filtered barium chloride.

[0023] A filtering mechanism for filtering is provided inside the filter box 1, and the filtering mechanism includes a filter cartridge 31, a toothed disc 32, a motor 33 and a gear 34. The filter cartridge 31 is provided inside the filter box 1, and the side wall of the filter cartridge 31 and the inner wall of the filter box 1 are rotatably connected via a connecting assembly. A toothed disc 32 is fixedly installed on the top of the filter cartridge 31, and a motor 33 is installed on the top of one side of the filter box 1 by screws. The output shaft of the motor 33 extends to the inside of the filter box 1 and a gear 34 located above the toothed disc 32 is fixedly installed thereon, and the gear 34 is meshedly connected with the toothed disc 32.

[0024] The connecting assembly includes a connecting block 41 and a connecting groove 42. The connecting blocks 41 are symmetrically welded to the top and bottom ends of the side walls of the filter cartridge 31. The inner wall of the filter box 1 is provided with multiple groups of connecting grooves 42 matching the connecting blocks 41. One end of the connecting block 41 away from the filter cartridge 31 extends into the interior of the connecting groove 42 and is rotatably connected to the connecting groove 42.

[0025] When in use, the motor 33 is started, and the output shaft of the motor 33 rotates, thereby driving the gear 34 to rotate accordingly. When the gear 34 rotates, it drives the toothed disc 32 meshing with it to rotate, and then the filter cartridge 31 rotates accordingly through the toothed disc 32. When the filter cartridge 31 rotates, the barium chloride filtered out of the internal mixed material can be thrown into the filter box 1 through the filter membrane on the surface of the filter cartridge 31, and then flows into the collection box 9, thereby accelerating the filtration efficiency of the filtration device for preparing high-purity barium chloride. When the filter cartridge 31 rotates, the connecting block 41 welded on its side wall rotates accordingly inside the connecting groove 42. The provided connecting block 41 is used to increase the stability of the filter cartridge 31 during the rotation operation.

[0026] A cleaning brush 10 is provided on one side of the inner wall of the filter cartridge 31, and the brush surface of the cleaning brush 10 is in contact with the inner wall of the filter cartridge 31. The top end of the cleaning brush 10 extends to the top outer side of the filter cartridge 31 and a mounting plate 11 is welded thereon. The other end of the mounting plate 11 is fixedly mounted on the inner wall of the filter box 1. When the filter cartridge 31 rotates, the cleaning brush 10 can continuously scrape the inner wall of the filter cartridge 31, thereby cleaning the residue attached to the inner wall to the inner bottom surface of the filter cartridge 31, thereby preventing the residue from clogging the filter membrane on the inner wall of the filter cartridge 31, and further accelerating the filtration efficiency of the filtration device for preparing high-purity barium chloride.

[0027] The interior of the filter cartridge 31 is provided with an extrusion mechanism that cooperates with the filter cartridge 31. The extrusion mechanism includes an extrusion plate 51 and a hydraulic cylinder 52. The interior of the filter cartridge 31 is provided with an extrusion plate 51. The top of the extrusion plate 51 is fixedly mounted with the top surface of the movable end of the hydraulic cylinder 52. The bottom surface of the fixed end of the hydraulic cylinder 52 is mounted on the bottom of the baffle 2 by bolts. Two hydraulic cylinders 52 are provided and distributed side by side. When in use, after the mixed material to be filtered is poured into the filter cartridge 31, the movable ends of the two hydraulic cylinders 52 are controlled to extend at the same time, thereby driving the extrusion plate 51 to move downward, and then extruding the mixed material. At this time, the barium chloride in the mixed material is continuously pressurized by the extrusion plate 51 and enters the filter box 1 through the filter membrane of the filter cartridge 31.

[0028] A discharge mechanism for discharging the slag is provided at the bottom of the filter cartridge 31, and the discharge mechanism includes a baffle 61, an L-shaped block 62 and an electric push rod 63. Baffles 61 of the same size are rotatably connected to both sides of the bottom of the filter cartridge 31 through bearings, and L-shaped blocks 62 are symmetrically welded to the bottom end of the side wall of the filter cartridge 31. The bottom surface of the L-shaped block 62 is hingedly connected to the electric push rod 63, and the top surface of the movable end of the electric push rod 63 is hingedly connected to the bottom of the baffle 61.

[0029] During use, when the filtering operation is completed, the movable ends of the electric push rods 63 are controlled to retract at the same time, so that the side close to the baffle 61 moves downward. At this time, the rotating connection between the baffle 61 and the bottom of the filter cartridge 31 rotates accordingly, and the movable ends of the electric push rods 63 are continuously retracted to release the baffle 61 from blocking the bottom of the filter cartridge 31. The filtered residue inside falls into the filter box 1 and then slides into the external waste collection box. There is no need to manually clean the residue, which saves time and effort.

[0030] Working principle: When the filtering device for preparing high-purity barium chloride is to be used, the mixed material to be filtered is first poured into the filter cartridge 31 inside the filter box 1, and then the movable ends of the two hydraulic cylinders 52 are controlled to extend at the same time, so that the extrusion plate 51 moves downward to extrude the mixed material. At this time, the barium chloride in the mixed material is continuously pressed by the extrusion plate 51 and is completely squeezed out. At the same time, the motor 33 is started to control the operation of the filtering mechanism, thereby causing the filter cartridge 31 to rotate and operate. Through the cooperation between the filter cartridge 31 and the extrusion plate 51, the filtering operation of the barium chloride in the mixed material can be accelerated. All the filtered barium chloride enters the filter box 1 through the filter membrane on the surface of the filter cylinder 31, and then flows into the collection box 9 for centralized collection. When the filter cylinder 31 rotates, the cleaning brush 10 can continuously scrape the inner wall thereof to prevent the residue from clogging the filter membrane on the inner wall, thereby further accelerating the filtration efficiency. When the mixed material is filtered, the collection box 9 is removed and replaced with an external waste collection box, and then the movable ends of the electric push rod 63 are controlled to retract at the same time, so that the baffle 61 releases the cover on the bottom of the filter cylinder 31. At this time, the residue falls into the filter box 1 and then slides into the external waste collection box.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
