Description

Technical Field

[0001] This utility model relates to the field of silica processing technology, specifically to an automatic and efficient silica screening and grading device. Background Technology

[0002] Silica, also known as hydrated silica, is a common name for powdered hydrated amorphous silica or silicic acid. Currently, silica is generally classified into precipitated silica and fumed silica based on its production method. Regardless of whether it's precipitated or fumed silica, the most basic unit constituting the particles is the primary silica particle.

[0003] In the process of preparing silica, it is necessary to classify and screen it. Existing classification and screening methods usually use multi-stage screening machines. However, the following problems still exist in the screening process: silica particles roll too fast on the multi-stage screening machine, resulting in insufficient screening of silica and poor screening effect. Multiple screenings are required, resulting in low work efficiency. In order to solve the above problems, we propose an automatic and efficient silica screening and grading device. Utility Model Content

[0004] The purpose of this invention is to provide an automatic and efficient screening and grading device for silica to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic and efficient screening and grading device for silica, comprising: The machine frame has four support legs fixedly installed on it, and three screening screens with increasing apertures from top to bottom. An L-shaped baffle plate is slidably connected to the frame. A pair of fixed seats are welded to each side wall of the frame. A screw is rotatably mounted on one pair of fixed seats, and a guide rod is welded to the other pair of fixed seats. A servo motor is fixedly mounted on one of the fixed seats and is connected to the screw. Two U-shaped rods are welded to the top wall of the L-shaped baffle plate. A movable seat is welded to the end of the U-shaped rod away from the L-shaped baffle plate. One movable seat is threaded to the screw through a threaded hole, and the other movable seat is slidably connected to the guide rod through a through hole. Two rotating rods are rotatably mounted on the top wall of the L-shaped baffle plate, and multiple stirring rods are fixedly mounted on the rotating rods.

[0006] Preferably, a drive motor is fixedly installed on the top wall of the L-shaped baffle by a mounting bracket. The output end of the drive motor is connected to a rotating rod. Both rotating rods are fixedly installed with pulleys, and the two pulleys are connected by a transmission belt.

[0007] Preferably, an end cover is fixedly installed on the top of the frame, and a feed hopper is fixedly installed on the end cover.

[0008] Preferably, three baffles are fixedly installed on the bottom wall of the frame, and the three baffles are respectively located at the bottom of the three screening screens, with a receiving box provided below each of the three screening screens.

[0009] Compared with the prior art, the beneficial effects of this utility model are: 1. In use, the silica particles to be screened are added into the inner cavity of the L-shaped baffle plate through the feed hopper. Then, the servo motor is started to drive the screw to rotate in the forward direction, so that the moving seat moves downward on the screw, thereby driving the L-shaped baffle plate to move downward on the frame. The silica particles are then driven to pass through three screening screens in sequence for full grading and screening. The L-shaped baffle plate can prevent the silica particles from rolling too fast on the screening screen, which would cause insufficient screening. 2. The drive motor provided in this utility model can drive two rotating rods to rotate during the movement of the L-shaped baffle plate through the cooperation of the pulley and the transmission belt. The rotating rods can drive the stirring rod to rotate, thereby stirring the silica particles accumulated on the L-shaped baffle plate and improving the screening effect. Attached Figure Description

A servo motor 8 is fixedly mounted on one of the fixed seats 5, and the servo motor 8 is connected to the screw 6 via a transmission connection. The L-shaped baffle 4... Two U-shaped rods 9 are fixedly welded to the top wall of the L-shaped baffle plate 4. A movable seat 10 is fixedly welded to the end of the U-shaped rod 9 away from the L-shaped baffle plate 4. One movable seat 10 is threadedly connected to the screw rod 6 through a screw hole, and the other movable seat 10 is slidably connected to the guide rod 7 through a through hole. Two rotating rods 11 are rotatably installed on the top wall of the L-shaped baffle plate 4. Multiple stirring rods 12 are fixedly installed on the rotating rods 11. The rotating rods 11 can drive the stirring rods 12 to rotate, so as to stir the white carbon black particles accumulated on the L-shaped baffle plate 4 and improve the screening effect.

[0014] A drive motor 13 is fixedly installed on the top wall of the L-shaped baffle plate 4 by a mounting bracket. The output end of the drive motor 13 is connected to a rotating rod 11. A pulley 14 is fixedly installed on each of the two rotating rods 11. The two pulleys 14 are connected by a transmission belt 15.

Then, the servo motor 8 is started, driving the screw 6 to rotate forward, causing the moving seat 10 to move downward on the screw 6, thereby driving the L-shaped baffle plate 4 to move downward on the frame 1. The silica particles are then passed through the three screening screens 3 in sequence for grading and screening. The L-shaped baffle plate 4 can prevent the silica particles from rolling too fast on the screening screens 3, which would cause insufficient screening. The drive motor 13 can drive the two rotating rods 11 to rotate during the movement of the L-shaped baffle plate 4 through the cooperation of the pulley 14 and the transmission belt 15. The rotating rods 11 can drive the stirring rod 12 to rotate, which can stir the silica particles accumulated on the L-shaped baffle plate 4 and improve the screening effect.
