Description

Technical Field

[0001] This utility model relates to the technical field of bran separation devices, specifically a special device for bran separation. Background Technology

[0002] A bran separation device is a mechanical device used to separate the bran mixture discharged from rice milling machines, rice polishing machines, and other equipment. Bran is a byproduct generated during grain processing, and these two substances need to be separated for better utilization or disposal.

[0003] Existing dedicated devices for rice bran separation have the following problems. These devices generally separate bran through vibration or rotational sieving. Referring to patent application CN212821171U, which discloses a rice bran separation device for rice processing, this invention employs a first separation tube and a second separation tube. When rice bran separation is required, rice is fed into the first separation tube through a feeding funnel. The feeding valve and the bran outlet valve are then closed. Two sets of hydraulic actuators can push two sets of push rod circular plates alternately or simultaneously. During this process, the rice impacts the two sets of push rod circular plates. As the two sets of hydraulic actuators accelerate, the speed and force of the impact increase. The separated rice flows out through a filter screen. The use of the first and second separation tubes makes the rice separation more uniform, facilitating the separation process in rice bran separation.

[0004] However, the above-mentioned technology uses a pusher plate and a filter screen to separate bran. During the separation process, some small bran particles inevitably get stuck in the micropores of the filter screen. Over time, this will affect the separation efficiency of the device. Furthermore, the existing device is not easy to clean the filter screen, so its practicality is generally limited. Utility Model Content

[0030] The feeding component 22 is located on the left side of the mounting box 1 to facilitate the feeding of rice into the screening component 21 for separation;

[0031] The material storage component 23 is installed inside the installation box 1 for collecting rice bran;

[0032] The dust collection assembly 24, located on the outside of the mounting box 1, is used to collect dust generated during device operation. The cleaning assembly includes a drive gear 213 fixedly mounted on the outside of the shaft 214. Brush rollers 218 are movably mounted on both the front and rear sides of the inner cavity of the mounting box 1. Driven gears 217 are movably mounted on both the front and rear sides of the left side of the inner cavity of the protective box 211. A control box 216 is fixedly mounted on the front side of the protective box 211, and the device operation can be controlled through the control box 216. The output end of the drive motor 212 movably passes through the interior of the protective box 211 and the right side of the mounting box 1 and is fixedly mounted on the screening cylinder 21. At the right end of 5, the left side of the sieving cylinder 215 is movably installed in the left side of the inner cavity of the mounting box 1. The outer side of the drive gear 213 meshes with the outer side of the driven gear 217. The right end of the brush roller 218 moves through the interior of the mounting box 1 and is fixedly installed in the left side of the driven gear 217. When the drive motor 212 is started, it can drive the shaft 214 to rotate the sieving cylinder 215 to sieve the bran in the rice. At the same time, the shaft 214 will drive the drive gear 213 to rotate the driven gear 217. Then the driven gear 217 will drive the brush roller 218 to rotate to clean the grooves on the brush roller 218.

[0033] The drive gear 213 and brush roller 218 facilitate the cleaning of the slots and holes on the sieve cylinder 215. During use, the drive motor 212 is started by the control box 216 to drive the shaft 214 to rotate the sieve cylinder 215 and separate the rice bran inside. At the same time, the shaft 214 drives the drive gear 213 to rotate the driven gear 217. Then, the driven gear 217 drives the brush roller 218 to rotate and clean the slots and holes of the sieve cylinder 215. It is easy to clean and has good practicality.

[0034] The second embodiment differs from the first embodiment in that: the feeding assembly 22 includes a protective box 221 fixedly installed on the left side of the mounting box 1. A feeding hopper 223 is fixedly installed on the top surface of the protective box 221. Feed pipes 222 are fixedly installed on both the front and rear sides of the top surface of the inner cavity of the protective box 221. The top end of the feeding pipe 222 penetrates the interior of the protective box 221 and the bottom surface of the feeding hopper 223, extending into the interior of the feeding hopper 223. The bottom end of the feeding pipe 222 movably penetrates the interior of the protective box 221 and the left side of the screening cylinder 215, extending into the interior of the screening cylinder 215. The storage assembly 23 includes a guide hopper 232 fixedly installed inside the mounting box 1. Cleaning windows 233 are provided on both the front and rear sides of the mounting box 1. A storage box 231 is movably installed on the bottom surface of the inner cavity of the mounting box 1. The guide hopper 232 is located below the screening cylinder 215, and the guide hopper 232 can prevent the bran from falling to the outside of the device. The dust collection assembly 24 includes a dust collection box 241 fixedly installed on the front and rear sides of the mounting box 1. Several mounting slots 242 are opened on one side of the dust collection box 241, and the several mounting slots 242 are linearly and evenly distributed on one side of the dust collection box 241. Fans 243 are fixedly installed inside the several mounting slots 242. A filter frame 244 is movably installed inside the dust collection box 241. The top surface of the filter frame 244 movably penetrates the interior of the dust collection box 241 and extends to the top surface of the dust collection box 241, and it is convenient to remove the filter frame 244 from the interior of the dust collection box 241 for cleaning. The opposite side of the dust collection box 241 penetrates the front and rear sides of the mounting box 1 and extends into the interior of the mounting box 1.

[0035] The fan 243 and filter frame 244 facilitate the collection of dust generated during the operation of the device. When in use, the fan 243 is turned on to generate suction, and the dust generated during the separation by the sieving component 21 is sucked into the dust collection box 241. The dust is then intercepted by the filter frame 244 to avoid affecting the working environment.

[0036] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0037] In use, the operator connects the device to power and then pours rice into the feed hopper 223. The rice then enters the sieving cylinder 215 through the discharge pipe 222. Next, the control box 216 starts the drive motor 212, which drives the shaft 214 to rotate the sieving cylinder 215, separating the rice bran from the chaff. Simultaneously, the shaft 214 drives the drive gear 213, causing the driven gear 217 to rotate. The driven gear 217 then drives the brush roller 218 to rotate, cleaning the grooves of the sieving cylinder 215. The fan 243 is then activated to generate suction. Finally, the sieving assembly 21 separates the rice. The generated dust will be sucked into the dust collection box 241 and intercepted by the filter frame 244. The bran separated by the sieving cylinder 215 will fall into the storage box 231 through the guide hopper 232. When the filter frame 244 needs to be cleaned, it can be pulled out of the dust collection box 241. After sieving, the storage box 231 can be taken out of the installation box 1 through the cleaning window 233 to clean the bran. Then, the drive motor 212 is turned off and the sieving cylinder 215 is opened to take the rice out of the sieving cylinder 215.
