Description

Technical Field

[0001] The utility model relates to the field of rice husk recovery, in particular to a rice husk recovery device for rice processing. Background Art

[0002] At present, a Chinese utility model with the announcement number CN215354494U discloses a rice husk recovery device for rice processing, which relates to the technical field of rice husk recovery, and is designed to solve the problem that the rice husk and debris are recovered together without separation during the existing rice husk recovery, resulting in low work efficiency. A classification box is arranged at the lower end of the recovery box, a frame is arranged inside the recovery box, a metal mesh is arranged on the inner wall of the frame, a rotating shaft is arranged at one end of the frame, a bearing is arranged outside the rotating shaft, a rotating frame is arranged at one end of the rotating shaft, a rice husk cavity is arranged inside the classification box, a debris cavity is arranged on one side of the rice husk cavity, a first limit plate is arranged on one side of the classification box, a second limit plate is arranged on the other side of the classification box, a slide groove is arranged on the front and rear surfaces of the classification box, and a sliding plate is arranged on the front and rear ends of the recovery box.

[0003] Although the existing recovery device can separate the debris in the rice husk through the metal mesh, there are still other problems in the use process, such as poor separation effect, inability to carry out continuous operation, and the debris intercepted on the metal mesh will accumulate more and more. When dealing with the debris, it is necessary to stop pouring the rice husk, and then replace the rice husk chamber below with the debris chamber and then flip the metal mesh. The operation is cumbersome and complicated, which reduces the recovery efficiency of the rice husk, and it does not have the dust collection and filtration function. The rice husk will generate a lot of dust after pouring and separating. If the powder contained in the dust is inhaled by the human body, it will cause damage to the respiratory tract and have a certain impact on the surrounding environment. In order to solve the above-mentioned problems, we propose a rice husk recovery device for rice processing. Utility Model Content

[0004] The utility model aims to provide a rice husk recovery device for rice processing, which solves the problem that the existing recovery device can achieve good separation effect and has dust collection and filtering functions.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: a rice husk recovery device for rice processing, comprising a box frame, an auger is rotatably connected to the inside of the box frame, a motor is fixedly sleeved on the other end of the auger, an arc-shaped metal screen is arranged inside the box frame, a mounting plate is symmetrically welded to the top of the arc-shaped metal screen, the mounting plate is bolted to the inside of the box frame, a first discharge port and a second discharge port are respectively provided on the other side and the front of the box frame, a box cover is bolted to the top of the box frame, a feed hopper is installed through the top of the box cover, a fixed frame is bolted to the top of the box cover, a suction fan is bolted to the inside of the fixed frame, an activated carbon filter screen is provided at the bottom of the fixed frame, and a suction port is provided on the top of the box cover.

[0006] The adoption of the above technical solution can achieve good separation effect and carry out sustainable recycling and separation, which reduces the workload of personnel. At the same time, it can have dust collection and filtration functions, thereby ensuring the health of surrounding workers, improving the surrounding environment, and is highly practical.

[0007] The utility model is further configured as follows: a protective cover is bolted to one side of the box frame.

[0008] By adopting the above technical solution and providing a protective cover, the motor can be protected to prevent the motor from being damaged when it is hit by foreign objects.

[0009] The utility model is further configured as follows: the top and the bottom of the activated carbon filter screen plate are both clamped with clamping seats, and the other sides of the two clamping seats are bolted to the fixing frame and the box cover respectively.

[0010] By adopting the above technical solution, the activated carbon filter screen can be limited by setting the holder to prevent the activated carbon filter screen from tipping over under the action of wind.

[0011] The utility model is further configured as follows: a dustproof net is bolted to one side of the fixing frame.

[0012] By adopting the above technical solution and setting a dustproof net, dust in the air can be prevented from falling into the suction fan.

[0013] The utility model is further configured as follows: the auger and the arc-shaped metal screen are both made of stainless steel.

[0014] By adopting the above technical solution, the auger and the arc-shaped metal screen have the characteristics of high strength, low density and excellent corrosion resistance.

[0015] The utility model is further configured that: the surfaces of the box frame and the box cover are coated with anti-corrosion paint.

[0016] By adopting the above technical solution and providing the anti-corrosion coating, the service life of the box frame and the box cover can be extended.

[0017] In summary, the utility model has the following beneficial effects:

[0018] 1. The utility model feeds rice husks from a feed hopper and starts a motor. The rice husks fall onto the arc-shaped metal screen after entering. The motor drives the auger to rotate after starting. The auger pushes the rice husks to move backwards during rotation. When the rice husks move, debris whose volume is smaller than the mesh of the arc-shaped metal screen will fall downwards and be discharged from the second discharge port, while the rice husks after being removed will be discharged outwards through the first discharge port, thereby achieving a good separation effect, carrying out sustainable recycling and separation, and reducing the workload of personnel.

[0019] 2. The utility model starts the suction fan, which will rotate the internal impeller. When the impeller rotates, it will discharge the air in the box cover to the outside to form a negative pressure state inside. When the box cover is under negative pressure, the dust-containing gas in the box frame will be sucked in through the suction port. The dust-containing gas will pass through the activated carbon filter screen before being discharged, which can have the dust collection and filtration function, thereby protecting the health of surrounding workers, improving the surrounding environment, and having high practicality.
