[0023] A filter for silica gel production comprises an outer shell 1, a side wall of which is provided with an electric heating plate 2, a side wall of which is provided with a cavity, the electric heating plate 2 is fixedly arranged inside the cavity and electrically connected to an external power supply, so as to maintain the temperature inside the filter and prevent the silica gel raw material from condensing.

[0024] A feed hopper 13 and a discharge hopper 14 are respectively arranged through the top wall and the bottom wall of the outer shell 1. A valve 15 is arranged inside the discharge hopper 14. The silica gel raw material enters the outer shell 1 from the feed hopper 13 for filtration. After the filtration is completed, the valve 15 is opened and the filtered silica gel raw material is discharged from the discharge hopper 14.

[0025] The bottom wall of the outer shell 1 is arranged as a funnel structure to facilitate the discharge of the silica gel raw material, and a support column 16 is arranged at the bottom to support the entire filter. A primary filter frame 3, a guide structure 4 and a vibrating filter screen 5 are arranged in sequence from top to bottom inside the outer shell 1. The primary filter frame 3 performs initial filtration on the silica gel raw material, the guide structure 4 can guide the raw material to the material guide pipe 8 and the filter residue to the residue discharge pipe 9, and the vibrating filter screen 5 can perform secondary filtration on the raw material to enhance the purity of the raw material.

[0026] The primary filter frame 3 is rotatably arranged inside the outer shell 1, and the primary filter frame 3 and the vibration filter screen 5 both include a bottom plate screen 17 and a side plate 18, wherein the filtering aperture of the bottom plate screen 17 in the primary filter frame 3 is larger than the filtering aperture of the bottom plate screen 17 in the vibration filter screen 5, and the primary filter frame 3 is vertically arranged with four side plates 18.

[0027] The silica gel raw material enters the outer shell 1 from the feed hopper 13 and falls onto the bottom plate screen 17 in the primary filter frame 3 below. The screen with a larger filter aperture allows the raw material to fall more quickly into the receiving funnel 6 in the guide structure 4 below. Since the receiving funnel 6 is fixedly arranged on the side wall of the outer shell 1, a conveying pipe 22 is arranged at the bottom outlet, a three-way valve 7 is arranged inside the conveying pipe 22, and a material guide pipe 8 and a slag discharge pipe 9 are arranged at the bottom of the conveying pipe 22. The three-way valve 7 is opened, so that the raw material screened out for the first time enters the material guide pipe 8 along the conveying pipe 22, and is then discharged to the vibrating filter screen 5 for secondary filtration.

[0028] An isolation block 19 is provided inside the primary filter frame 3, and a rotating shaft 20 is fixedly provided inside the isolation block 19 to prevent the rotating shaft 20 from directly contacting the raw material. The rotating shaft 20 is rotatably provided on the side wall of the outer shell 1 and is fixedly connected to the output end of a rotating motor 21 provided on the outer wall of the outer shell 1. The rotating motor 21 is provided as a self-locking reduction motor with a self-determined rotation angle.

[0029] After the initial screening is completed, the rotating motor 21 is started to drive the rotating shaft 20 to rotate 180 degrees, so that the primary filter frame 3 is turned over, and the screened filter residue is turned over and falls into the slag discharge pipe 9 below along the conveying pipe 22. Since the outlet of the slag discharge pipe 9 passes through the side wall of the outer shell 1, the filter residue is discharged to the outside for centralized treatment.

[0030] The outlet of the material guide pipe 8 is arranged above the inclined upper end of the bottom plate screen 17 in the vibrating filter screen 5 , and the raw materials screened out for the first time fall into the bottom plate screen 17 .

[0031] The vibration filter screen 5 includes a vibration assembly 10 and a movable baffle 11. The vibration assembly 10 includes a vibration motor 23, a spring group 24, and a support block 25. A vibration motor 23 is arranged at the bottom of the bottom plate screen 17 in the vibration filter screen 5. The vibration filter screen 5 is vertically provided with three side plates 18, and a spring group 24 is fixedly arranged at the inclined upper end. The top of the spring group 24 is fixedly connected to the support block 25 fixedly arranged on the side wall of the outer shell 1, and the inclined lower end is fixedly arranged on the side wall of the outer shell 1, and a guide plate 26 is also vertically arranged.

[0032] The vibration motor 23 is started to drive the bottom plate screen 17 to achieve a certain vibration under the cooperation of the spring group 24, thereby accelerating the speed of raw material filtration. Raw materials that meet the screening particle size are filtered through the bottom plate screen 17 to the bottom wall of the funnel below, and are discharged to the outside through the discharge hopper 14 for centralized storage. The unfiltered filter residues are gathered at the outlet along the guide plate 26.

[0033] The movable baffle 11 is slidably arranged on the outer periphery of the movable screw rod 12. The movable baffle 11 is movably erected on the inclined lower end of the vibrating filter screen 5. The movable baffle 11 penetrates the bottom plate screen 17 and is movably arranged at the outlet of the guide plate 26. The outlet of the guide plate 26 also penetrates the side wall of the outer shell 1 to be provided with another slag discharge pipe 9. The bottom wall of the outer shell 1 is provided with a micro motor 27. The movable screw rod 12 is arranged at the output end of the micro motor 27. The movable baffle 11 is slidably arranged on the outer periphery of the movable screw rod 12.

[0034] At this time, the micro motor 27 is started to drive the movable screw 12 to rotate, thereby causing the movable baffle 11 to move downward. When it moves to the bottom of the movable screw 12, the top of the movable baffle 11 is flush with the inclined lower end of the bottom plate screen 17, and the filter residue continues to move along the outlet of the guide plate 26 to another residue discharge pipe 9 until it is discharged to the outside of the filter for centralized treatment.
