Description

Technical Field

[0001] This utility model relates to the field of rice impurity removal, and in particular to a dust prevention device for rice impurity removal. Background Technology

[0002] The rice impurity removal dustproof device is a device used to suck up dust and rice husks during the rice hulling process. It can suck up and collect the removed rice husks and dust, reducing dust and improving the cleanliness of the working environment.

[0003] Existing rice impurity removal dustproof devices cannot separate the sucked-in rice husks and dust during use; they can only collect the rice husks and dust together. This results in the need for re-sieving when recycling rice husks to make feed, which affects processing efficiency.

[0004] Therefore, to address the problem that existing rice impurity removal dustproof devices cannot separate sucked-in rice husks and dust during use, resulting in the need for re-sieving when recycling rice husks for feed production and affecting processing efficiency, a rice impurity removal dustproof device can be designed. By setting up a negative pressure fan, a negative pressure can be created inside the diversion pipe during operation. The pressure difference is used to adsorb dust and rice husks to the right side of the diversion pipe. The screen can block the rice husks, while the dust will move to the right side of the diversion pipe through the screen holes. The rice husks will fall downward into the inside of the inlet pipe. Furthermore, by setting up a first drive motor, its output end will drive the first drive gear to rotate during operation. When the first drive gear rotates, it can drive the first driven gear meshing with it to rotate. When the first driven gear rotates, it can drive the rotating shaft to rotate, thereby driving the brush rod to clean the screen. Utility Model Content

[0005] To overcome the problem that existing rice impurity removal dust prevention devices cannot separate sucked-in rice husks and dust during use, which leads to the need for re-screening when recycling rice husks to make feed, thus affecting processing efficiency.

[0006] The technical solution of this utility model is as follows: a dustproof device for removing impurities from rice, including an equipment box; it also includes an inlet pipe, a diversion pipe, a screen, a negative pressure fan, a rotating shaft, a first driven gear, a first drive motor, a first drive gear, and a brush rod. The inlet pipe is provided on the left side of the top surface of the equipment box, and the top of the inlet pipe is connected to the diversion pipe. The screen is installed at the rear position of the inner surface of the diversion pipe. The negative pressure fan is installed on the right side of the top surface of the diversion pipe. The rotating shaft is rotatably connected through the right side surface of the inlet pipe. The right end of the rotating shaft is connected to the first driven gear. The first drive motor is installed on the right side surface of the inlet pipe at the front position of the rotating shaft. The output end of the first drive motor is provided with the first drive gear, which meshes with the first driven gear. The brush rod is provided on the left side surface of the rotating shaft, and the bristles of the brush rod are in contact with the left side surface of the screen.

[0007] Preferably, by setting up a negative pressure fan, a negative pressure can be formed inside the diversion pipe during operation. The pressure difference is used to adsorb dust and rice husks to the right side of the diversion pipe. The screen can block the rice husks, while the dust will move to the right side of the diversion pipe through the screen holes. The rice husks will fall downwards into the inside of the inlet pipe. Furthermore, by setting up a first drive motor, its output end will drive the first drive gear to rotate during operation. When the first drive gear rotates, it can drive the first driven gear meshing with it to rotate. When the first driven gear rotates, it can drive the rotating shaft to rotate, thereby driving the brush rod to clean the screen and prevent the mesh holes from clogging. This achieves the separation of dust and rice husks, thus solving the problem that the existing dust prevention device for rice impurity removal cannot separate the sucked rice husks and dust during use, which requires re-screening when recycling rice husks to make feed, affecting processing efficiency.

[0008] Preferably, a flow guide is installed on the right side surface of the diversion pipe, one end of the conveying pipe is connected to the right side of the flow guide, the other end of the conveying pipe is connected to the treatment box, the bottom surface of the treatment box is connected to the top surface of the equipment box, and a water inlet is provided on the rear side of the upper surface of the treatment box.

[0009] Preferably, a water outlet pipe is provided on the right side surface of the treatment tank, and a manual valve is provided on the upper side of the outer surface of the water outlet pipe.

[0012] Preferably, a receiving box is slidably connected to the bottom of the inner surface of the equipment box, and two symmetrical positioning grooves are opened at the bottom of the inner surface of the equipment box.

[0013] Preferably, a protective door is installed on the front surface of the equipment box via a hinge, an observation window is provided on the front surface of the protective door, and a handle is installed on the right side of the observation window on the front surface of the protective door.

[0014] The beneficial effects of this utility model are:

[0015] 1. By installing a negative pressure fan, a negative pressure can be created inside the diversion pipe during operation. The pressure difference attracts dust and rice husks to the right side of the diversion pipe. The screen can block the rice husks, while the dust moves to the right side of the diversion pipe through the screen holes. The rice husks fall downwards into the inlet pipe. Furthermore, by installing a first drive motor, its output end drives the first drive gear to rotate during operation. When the first drive gear rotates, it drives the first driven gear meshing with it to rotate. When the first driven gear rotates, it drives the shaft to rotate, thereby driving the brush rod to clean the screen and prevent the mesh from clogging. This achieves the separation of dust and rice husks, thus solving the problem that existing rice impurity removal dust prevention devices cannot separate the sucked-in rice husks and dust during use, which requires re-screening when recycling rice husks to make feed, affecting processing efficiency.

The screen 4 can block the rice husks, while the dust will move to the right side of the diversion pipe 3 through the screen holes of the screen 4. The rice husks will fall down into the interior of the inlet pipe 2. By setting a first drive motor 8, the output end of the motor will drive the first drive gear 9 to rotate during operation. When the first drive gear 9 rotates, it can drive the first driven gear 7 that meshes with it to rotate. When the first driven gear 7 rotates, it can drive the rotating shaft 6 to rotate, thereby driving the brush rod 10 to clean the screen 4 and prevent the mesh from clogging, thus achieving the separation of dust and rice husks.

[0024] Please see Figures 1-4In this embodiment, a guide shroud 11 is installed on the right side surface of the diversion pipe 3. One end of the conveying pipe 12 is connected to the right side of the guide shroud 11, and the other end of the conveying pipe 12 is connected to the processing box 13. The bottom surface of the processing box 13 is connected to the top surface of the equipment box 1. A water inlet 14 is provided on the rear side of the upper surface of the processing box 13. By setting the guide shroud 11, dust can be collected into the interior of the conveying pipe 12 and transported to the interior of the processing box 13 through the conveying pipe 12.

[0026] During operation, the dust is collected into the conveying pipe 12 by the guide hood 11 and transported to the treatment tank 13 through the conveying pipe 12. Water and flocculant are added to the treatment tank 13 through the water inlet 14 to flocculate the dust. The water in the treatment tank 13 can be drained by the manual valve 16 and the water outlet 15 for a new round of water addition. The second drive motor 18 drives the second drive gear 19 to rotate during operation. The rotation of the second drive gear 19 drives the second driven gear. The 20 rotates, thereby driving the stirring shaft to rotate, thus increasing the flocculation rate. By setting the support legs 21 and the gaskets 22, the overall stability of the device during use can be improved, and the service life of the device can be extended.

[0027] Through the above steps, by setting up a negative pressure fan 5, a negative pressure can be formed inside the diversion pipe 3 during operation. The pressure difference is used to adsorb dust and rice husks to the right side of the diversion pipe 3. The screen 4 can block the rice husks, while the dust will move to the right side of the diversion pipe 3 through the screen holes of the screen 4. The rice husks will fall downwards into the interior of the inlet pipe 2. Furthermore, by setting up a first drive motor 8, its output end will drive the first drive gear 9 to rotate during operation. When the first drive gear 9 rotates, it can drive the first driven gear 7 meshing with it to rotate. When the first driven gear 7 rotates, it can drive the rotating shaft 6 to rotate, thereby driving the brush rod 10 to clean the screen 4 and prevent the mesh from clogging. This achieves the separation of dust and rice husks, thus solving the problem that the existing rice impurity removal dust prevention device cannot separate the sucked rice husks and dust during use, which leads to the need to re-screen when recycling rice husks to make feed, affecting processing efficiency.
