Description

Technical Field

[0001] This utility model relates to the field of rice bran processing technology, specifically to a dust removal device for rice bran processing. Background Technology

[0002] Rice bran is mainly made from the pericarp, seed coat, outer endosperm, aleurone layer, and embryo. Therefore, a small amount of rice husks and a certain amount of dust and microorganisms will be mixed in during the processing. So it can only be used as feed and is the main by-product of rice processing. When using rice bran, it needs to be processed. Dust and rice husks are easily generated during processing. Therefore, appropriate rice bran dust removal devices are used to remove dust during rice bran processing.

[0003] Traditional dust removal devices have a drawback: the filters are prone to clogging and require frequent cleaning. Cleaning the filters stops the dust removal process, thus reducing the efficiency of rice bran processing. Utility Model Content

[0004] The purpose of this utility model is to provide a dust removal device for rice bran processing, which has a filter screen that will not clog and can continuously perform dust removal, thereby improving the efficiency of rice bran processing and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dust removal device for rice bran processing, comprising a dust removal box, a special-shaped tube, a pushing mechanism, and a control box. The special-shaped tube is installed at the upper end of the dust removal box. A suction pipe is installed on the left side of the dust removal box at the left end of the special-shaped tube, and a suction nozzle is installed at the other end of the suction pipe. A sleeve is installed on the right side of the dust removal box at the right end of the special-shaped tube, and a suction fan is installed inside the sleeve. Two round shafts are rotatably installed in the two pipes in the middle of the special-shaped tube, and a filter screen is installed on the left side of the round shafts. Two sealing plates are symmetrically installed on the two round shafts. Spur gears are installed extending from the upper ends of the two round shafts out of the special-shaped tube, and the two spur gears are meshed together. A pushing mechanism is installed at the lower left end of the dust removal box. A baffle is inserted into the right outlet of the dust removal box from the top, and a handle is installed on the top of the baffle.

[0006] Preferably, the dust collector housing has four feet arranged in a rectangular array at its bottom corners. These four feet provide stable support for the dust collector housing.

[0007] Preferably, the bottom of the two pipes of the irregularly shaped tube is provided with a rectangular notch close to the left side of the filter screen. The rectangular notch facilitates the falling of impurities.

[0008] Preferably, a motor is installed on the top of the dust collector housing, and the motor output shaft is connected to the front round shaft via a flange. By setting up the motor, the sealing plates on the two round shafts can be rotated.

[0009] Preferably, the sleeve has a dust outlet on its right side, and a collection bag is installed at the end of the dust outlet. By setting up the collection bag, dust can be collected.

[0010] Preferably, the pushing mechanism consists of an electric push rod, four guide rods, and a push plate. The electric push rod is installed at the lower center of the left side panel of the dust collector, and the four guide rods are slidably installed around the electric push rod and on the left side panel of the dust collector. The push plate is installed on the extended end of the electric push rod and the right end of the four guide rods. By setting up the pushing mechanism, impurities are squeezed and pushed out of the dust collector.

[0011] Preferably, a diversion plate is installed inside the left side panel of the dust collector, above the push plate. By setting the diversion plate, impurities are diverted to the bottom of the dust collector.

[0012] Preferably, the control box is installed on the upper front of the dust collector housing, and is electrically connected to the electric push rod, the motor, and the dust collection fan. The control box allows for convenient overall control of the dust collection process.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] When this utility model is in use, the motor slowly drives two round shafts to rotate, and the rotation of the two round shafts drives the two sealing plates on them to rotate. When the two sealing plates in one of the pipes of the special-shaped tube block the pipe, the rice husks and some larger impurities on the internal filter screen will fall from the rectangular gap below to the bottom of the dust collection box. Conversely, the other pipe of the special-shaped tube is unobstructed and can continue to collect dust, thus ensuring that the filter screen will not be blocked and that dust collection can be carried out continuously, thereby improving the efficiency of rice bran processing.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 4 This utility model provides a dust removal device for rice bran processing: A dust removal device for rice bran processing includes a dust removal box 1, a special-shaped tube 9, a pushing mechanism, and a control box 21. The bottom corners of the dust removal box 1 are equipped with four feet 3 arranged in a rectangular array. The special-shaped tube 9 is installed at the upper part of the inside of the dust removal box 1. A suction pipe 8 is installed on the left side of the dust removal box 1 at the left end of the special-shaped tube 9. A suction nozzle 7 is installed at the other end of the suction pipe 8. A sleeve 16 is installed on the right side of the dust removal box 1 at the right end of the special-shaped tube 9. A suction fan 17 is installed inside the sleeve 16. A dust outlet 18 is provided on the right side of the sleeve 16. A collection bag 19 is installed at the end of the dust outlet 18. When the suction fan 17 works, it sucks dust in from the suction nozzle 7. The suction pipe 8 enters the special-shaped tube 9. When the dust passes through the filter screen 11, rice husks and some larger impurities are filtered out. A small amount of dust will enter the collection bag 19 for collection.

[0022] Two cylindrical shafts 15 are rotatably installed inside the two pipes in the middle of the shaped tube 9. A filter screen 11 is installed on the left side of the cylindrical shaft 15. A rectangular notch 10 is provided at the bottom of the two pipes of the shaped tube 9, close to the left side of the filter screen 11. Two sealing plates 12 are symmetrically installed on the two cylindrical shafts 15. A spur gear 13 is installed on the upper end of the two cylindrical shafts 15 extending out of the shaped tube 9. The two spur gears 13 are meshed and connected. A motor 14 is installed on the top of the dust collection box 1. The output shaft of the motor 14 is connected to the front cylindrical shaft 15 through a flange. During the dust collection process, the motor 14... The slow operation drives the front round shaft 15 and the spur gear 13 mounted on it to rotate. The rotation of the spur gear 13 drives another spur gear 13 to rotate, which in turn drives the two round shafts 15 to rotate. The rotation of the two round shafts 15 drives the two sealing plates 12 on them to rotate. When the two sealing plates 12 in one of the pipes of the shaped tube 9 block the pipe, the rice husks and some larger impurities on the internal filter screen 11 will fall from the rectangular notch 10 below it to the bottom of the dust collection box 1. Conversely, the other pipe of the shaped tube 9 is unobstructed and dust collection can continue.

[0023] A material pushing mechanism is installed on the lower left side of the dust collector 1. This mechanism consists of an electric push rod 4, four smooth rods 5, and a push plate 2. The electric push rod 4 is installed in the middle of the lower left side plate of the dust collector 1. The four smooth rods 5 are slidably installed around the electric push rod 4 and the left side plate of the dust collector 1. The push plate 2 is installed on the extended end of the electric push rod 4 and the right end of the four smooth rods 5. A guide plate 6 is installed inside the left side plate of the dust collector 1 above the push plate 2. A baffle 20 is inserted into the upper right outlet of the dust collector 1, and a handle is installed on the top of the baffle 20. The electric push rod 4 can be periodically activated via the control box 21. The operation of the electric push rod 4 drives the push plate 2 to move to the right, squeezing the rice and large impurities. When the baffle 20 is nearly full, it is pulled out, and the electric push rod 4 drives the push plate 2 to move to the right, pushing out the squeezed rice and large impurities. The control box 21 is installed on the upper front of the dust collector 1 and is electrically connected to the electric push rod 4, the motor 14, and the dust collection fan 17.

[0024] All motors in this utility model are designed using the small servo motor model 14HS2408. This model of motor is only for reference by those skilled in the art. Those skilled in the art can select motors with the same parameters and functions for installation and debugging according to actual production needs. This utility model will not elaborate further.

[0025] In use, the dust extraction fan 17 and motor 14 are activated via the control box 21. The dust extraction fan 17 draws dust in through the suction nozzle 7, and the suction pipe 8 enters the shaped tube 9. When the dust passes through the filter screen 11, rice husks and some larger impurities are filtered out. A small amount of dust is collected in the collection bag 19. During the dust extraction process, the motor 14 slowly drives the front round shaft 15 and the spur gear 13 mounted on it to rotate. The rotation of the spur gear 13 drives another spur gear 13 to rotate, thereby driving the two round shafts 15 to rotate. The rotation of the two round shafts 15 drives the other... When the two sealing plates 12 rotate, when one of the pipes in the shaped tube 9 is blocked by the two sealing plates 12, the rice husks and some larger impurities on the internal filter screen 11 will fall from the rectangular gap 10 below to the bottom of the dust collection box 1. Conversely, when the other pipe of the shaped tube 9 is unobstructed, dust collection can continue. The electric push rod 4 can be started periodically through the control box 21. The operation of the electric push rod 4 drives the push plate 2 to move to the right to squeeze the rice and large impurities. When the squeezing is full, the baffle 20 is pulled out, and the operation of the electric push rod 4 drives the push plate 2 to move to the right to push out the squeezed rice and large impurities.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
