[0002] Garnet, also known as garnet, is a silicate mineral. Garnet has a moderate hardness and good chemical stability. It is commonly used as an abrasive for grinding and polishing materials such as glass and ceramics. It can also be used as a coating to make sandpaper, sandcloth, grinding wheels, etc., for polishing various metals, woods, rubbers, and plastics. At the same time, in the filtration system for deep water treatment, almandine is mainly selected as the water filtration sand.

[0003] The raw materials of garnet mainly come from various ores. The collected raw materials usually contain a lot of impurities, gravel, and dead stones, so subsequent processing is required.

[0058] Meanwhile, a rotating disk 113 is fixedly mounted on the screening shaft, and the rotating disk 113 is adapted to rotate synchronously with the screening shaft. An eccentric column 114 is fixedly mounted on the rotating disk 113, and a crank 115 is fixedly mounted on the eccentric column 114. A connecting rod 116 is hingedly connected to one end of the crank 115 away from the eccentric column 114, and a sliding column 118 is hingedly connected to one end of the connecting rod 116 away from the crank 115.

[0059] A waist groove 117 is provided on the screening frame 120, and a slide column 118 passes through the waist groove 117 and is fixedly installed with the screen plate 18, so that when the turntable 113 rotates, the crank 115 and the connecting rod 116 can drive the slide column 118 to slide in the waist groove 117, and then drive the screen plate 18 to reciprocate, so that the screen plate 18 vibrates reciprocatingly, thereby better screening the garnet.

[0060] In order to be able to overhaul the crushing box 14, Figure 4 As shown, the crushing box 14 is divided into a fixed box located at the lower end, and a cover plate hinged on the fixed box, and a tripod 141 is fixedly installed on the cover plate. At the same time, a cylinder 119 is fixedly installed on the crushing frame 11, and the output end of the cylinder 119 is hinged to the tripod 141, so that when the cylinder 119 contracts, the cover plate can be opened to process the interior of the crushing box 14.

[0061] In order to prevent the dust generated by crushing from polluting the air, Figure 1 As shown, a cover shell 4 is provided at the outer end of the crushing mechanism 1, and the cover shell 4 is used to shield dust. At the same time, an observation window 41 is provided on the cover shell 4, and the observation window 41 is used to observe the working condition of the crushing mechanism 1 at any time;

[0062] The housing 4 is connected with an air intake pipe 5, and one end of the air intake pipe 5 away from the housing 4 is connected with a dust removal mechanism 2, which is used to process a large amount of dust generated by the crushing mechanism 1;

[0063] like Figures 5 - 6 As shown, the dust removal mechanism 2 includes a dust removal frame 21, on which a dust removal box 23 is fixedly mounted, and the bottom of the dust removal box 23 is connected to the suction pipe 5, so as to facilitate the introduction of dust into the dust removal box 23;

[0064] At the same time, a dust collecting plate 214 is fixedly installed on the upper end of the dust removal box 23. The dust collecting plate 214 is provided with a plurality of groups of holes (not shown in the figure), and a dust collecting mechanism 7 is installed in the holes. The dust collecting mechanism 7 is used for filtering dust;

[0065] like Figure 8 As shown, the dust collecting mechanism 7 includes a cloth bag (not shown in the figure) fixedly mounted on the dust collecting plate 214, the cloth bag having a brim, and mounting holes are arranged around the holes of the dust collecting plate 214, so that the cloth bag is fixed to the dust collecting plate 214 by fasteners;

[0066] At the same time, a skeleton structure is arranged inside the cloth bag to prop up the cloth bag. The skeleton structure includes multiple groups of steel bars 71 arranged vertically. The multiple groups of steel bars 71 are arranged in a circle, and multiple groups of steel rings 74 are evenly arranged on the steel bars 71 along the height direction, so that the cloth bag can always be supported in the height direction.

[0067] A bottom plate 73 is fixed at the bottom of the plurality of steel bars 71, and a top plate 72 is fixed at the top of the plurality of steel bars 71, so as to form a complete skeleton structure;

[0068] During installation, the skeleton structure is placed inside the bag to support the bag as a whole.

[0069] Continue to refer Figures 5 - 6 A sealing plate 28 is provided at the top of the dust box 23 to close the dust box 23. At the same time, a dust collecting hopper 25 is provided at the lower end of the dust box 23. A first fan 26 is provided at the lower end of the dust collecting hopper 25. When the first fan 26 is turned on, the dust in the dust box 23 can be drawn out through the first fan 26.

[0070] Furthermore, an inspection window 27 is provided on the dust hopper 25 to facilitate timely handling of abnormal conditions in the dust hopper 25 .

[0071] like Figure 1 , Figure 5 and Figure 7As shown, an exhaust port 29 is connected to the upper end of the dust removal box 23. This exhaust port 29 is used to discharge the filtered air. The exhaust port 29 is connected to a exhaust pipe 6, and the exhaust pipe 6 is connected to a discharge mechanism 3. The discharge mechanism 3 is used to discharge the filtered air into the outside.

[0072] The discharge mechanism 3 includes a discharge rack 31 fixedly arranged in the production workshop. A second fan 32 is fixedly installed on the discharge rack 31. The input end of the second fan 32 is connected to the exhaust pipe 6, and the output end of the second fan 32 is connected to a tail pipe 33. The tail pipe 33 is connected to the outside and is used to discharge the filtered air.

[0073] Embodiment 2:

[0074] During the long-term filtration of dust, a large amount of dust will adhere to the outer ring of the cloth bag. If not cleaned, it will surely affect the dust collection effect of the cloth bag.

[0075] To solve the above problems, as Figure 5 and Figure 6 shown, a side plate 24 is fixedly installed on the dust removal rack 21. A high-pressure air pump 210 is fixedly installed on the side plate 24. The output end of the high-pressure air pump 210 is connected to a plurality of valve bodies 211. The valve body 211 is connected to a shunt pipe 212, and a nozzle 213 matching the dust collection mechanism 7 is arranged on the shunt pipe 212. The nozzle 213 is positioned opposite the top plate 72. At the same time, a through ventilation hole (not marked in the figure) is arranged on the top plate 72. Thus, when the high-pressure air pump 210 is started, high-pressure gas can be sprayed into the interior of the cloth bag through the nozzle 213 and the ventilation hole to blow the cloth bag from the inside, and then the dust adhering to the outer ring of the cloth bag can be removed.

[0076] To further improve the effect of dust removal, as Figures 8 - 11 shown, a vibration mechanism 8 is installed at the steel ring 74 of the framework structure. The vibration mechanism 8 acts on the inner side of the cloth bag through vibration to cooperate with the high-pressure gas to remove dust from the cloth bag.

[0077] The vibration mechanism 8 includes a vibration plate 81 fixedly installed on the steel ring 74. A second motor 88 is fixedly installed at the bottom of the vibration plate 81. The output end of the second motor 88 is fixedly installed with a gear 82. The gear 82 is adapted to rotate under the drive of the second motor 88.

[0078] Meanwhile, two sets of vibration bodies are installed on the vibration plate 81. The vibration body includes a vertical plate 89 fixedly installed on the vibration plate 81. A fixed ring 83 is fixedly installed on the vertical plate 89. A locking shaft 84 is slidably inserted through the fixed ring 83. A toothed plate 86 is fixedly installed at a position of the locking shaft 84 far from the fixed ring 83. Meanwhile, a first spring 85 is installed between the toothed plate 86 and the fixed ring 83. Thus, the locking shaft 84 can slide on the fixed ring 83 to drive the toothed plate 86 to move horizontally synchronously. In this embodiment, a boss (not marked in the figure) is provided on the locking shaft 84 to prevent the locking shaft 84 from slipping out of the fixed ring 83 when sliding;

[0079] And a rack 87 is provided at the lower end of the toothed plate 86. The rack 87 meshes with the gear 82. Thus, when the gear 82 rotates, the toothed plate 86 can be driven to slide horizontally through the meshing rack 87, and the first spring 85 can be stretched or compressed;

[0080] Continue to refer to Figures 10 - 11 , a chute 861 is formed on the toothed plate 86. An independent tooth 810 is slidably arranged in the chute 861. And a second spring 811 is fixedly installed between the independent tooth 810 and the toothed plate 86. Thus, in the initial state, due to the action of the second spring 811, there is a certain distance between the independent tooth 810 and one end of the rack 87, and this distance is the tooth pitch length of the rack 87;

[0081] In summary, in the initial state, the toothed plate 86 is received inside the vibration plate 81;

[0082] When it is necessary to vibrate the cloth bag, start the second motor 88 to drive the gear 82 to rotate. Thus, as the gear 82 rotates, the toothed plate 86 is driven to move horizontally and slowly move outwards to be close to the inner side of the cloth bag. When the gear 82 reaches the end of the rack 87, the end of the toothed plate 86 contacts the inner side of the cloth bag;

[0083] When the gear 82 crosses the end of the rack 87, it will mesh with the independent tooth 810. After the rack 87 meshes with the independent tooth 810, the independent tooth 810 will be driven to approach the rack 87, and under the action of the second spring 811, the toothed plate 86 will be driven to continue to approach the cloth bag and collide with the cloth bag;

[0084] As the gear 82 continues to rotate, when the gear 82 disengages from the independent tooth 810, the independent tooth 810 will reset under the action of the second spring 811 and drive the toothed plate 86 to reset a short distance, so that the end of the toothed plate 86 moves away from the cloth bag;

[0085] Thus, through the continuous rotation of the above-mentioned gear 82, intermittent meshing with the independent tooth 810 can be achieved to drive the end of the toothed plate 86 to vibrate the cloth bag intermittently to enhance the effect of dust cleaning;

[0086] When the toothed plate 86 needs to return to the initial position, the second motor 88 can be reversed.

[0087] In this embodiment, multiple sets of vibration mechanisms 8 can be provided to vibrate the whole cloth bag.

[0088] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
