Description

Technical Field

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

[0002] Rice bran (current national standard rice bran) is mainly made from the pericarp, seed coat, aleurone layer, and embryo. Therefore, a small amount of rice husks, a certain amount of dust, and microorganisms will be mixed in during the processing. So it can only be used for feed and is the main by-product of rice processing.

[0003] The patent with the publication number CN219442486U discloses a rice bran recovery device for rice processing. It includes a recovery box and a water tank. A partition is fixedly arranged in the recovery box. Above the partition, a collection bucket is fixedly arranged. A rotating shaft is rotatably connected in the collection bucket. Dispersing rods are fixedly arranged on the rotating shaft. A first dust suction mechanism is arranged on the collection bucket. An air inlet is opened on one side below the partition. This device improves the efficiency and effect of separating dust in rice bran. Through the water tank and the spraying mechanism, the dust is collected uniformly, avoiding affecting the working environment and the health of workers when dealing with the collected dust.

[0004] However, when separating the dust in the rice bran, whether the rice bran enters the collection bucket, the diversion plate, the guide plate, or the receiving hopper, due to the relatively light weight of the rice bran itself, it is difficult to quickly discharge and fall, and it is very easy to cause the accumulation of rice bran. As a result, when dispersing, stirring, and blowing the rice bran, it is difficult to quickly pat and blow out all the dust inside the rice bran, thus affecting the processing efficiency and effect of rice bran recovery, and further affecting the quality of rice bran. For this reason, a rice bran recovery device for rice processing is proposed to solve the problem that it is difficult to quickly remove the dust inside the rice bran in the existing rice bran recovery device.

DETAILED DESCRIPTION

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] Embodiment: Please refer to Figure 1-6 , a rice bran recovery device for rice processing, including a processing box 1. The top and bottom of the processing box 1 are respectively provided with a feed inlet 2 and a discharge port 3. Two sets of centrally symmetric inclined guide plates 4 are arranged in the inner cavity of the processing box 1. A groove 5 is opened at the middle position of the top of the inclined guide plate 4. A connecting rod 6 is arranged through the inner cavity of the groove 5. The inclined guide plate 4 is rotationally connected to the inner cavity of the processing box 1 and the inclined guide plate 4 and the connecting rod 6 by a rotating shaft 7. A motor 8 is fixedly connected to the top of the processing box 1. Two symmetrically arranged rotating plates 9 are fixedly connected to the output shaft of the motor 8. The connecting rod 6 penetrates through the processing box 1 and a connecting plate 10 is fixedly connected to the top. A spring 11 is arranged at the bottom of the connecting plate 10. An activity groove 12 is opened on the inner cavity wall of the processing box 1. The two ends of the processing box 1 are hollow and through holes 13 for blowing air and dust suction slots 14 are respectively opened on the inner cavity walls at both ends. A blower 15 is fixedly connected to the top of the processing box 1. A dust suction mechanism 16 and a feeding mechanism 17 are respectively arranged at one end and the top of the processing box 1.

[0026] Furthermore, when the rotating plate 9 is horizontal, it is located at the bottom of the connecting plate 10. The top and bottom of the spring 11 are respectively connected to the connecting plate 10 and the processing box 1.

[0027] Furthermore, the rotating shaft 7 connecting the inclined guide plate 4 and the processing box 1 is located in the inner cavity of the activity groove 12. The exhaust end of the blower 15 communicates with the hollow area of the box wall of the processing box 1 where the blowing hole 13 is located.

[0028] Furthermore, the dust suction mechanism 16 includes a water tank 161 fixedly connected to one end of the processing box 1. A water inlet is opened at the top of the water tank 161. A dust suction pump 162 is arranged at the top of the water tank 161. The suction end of the dust suction pump 162 communicates with the hollow area of the box wall of the processing box 1 where the dust suction slot 14 is located.

[0029] Further, the bottom of the dust suction pump 162 is interconnected with a conduit 163. The bottom end of the conduit 163 is close to the bottom of the inner cavity of the water tank 161. One end of the water tank 161 is provided with a drain pipe 164, and a valve is arranged outside the drain pipe 164. When water enters the water tank 161 from the water inlet, and at the same time the air blown out through the air blowing holes 13 blows the dust towards the dust suction slot 14, the dust suction pump 162 is turned on, so that suction is generated in the dust suction slot 14. Then, the sucked dust is discharged into the water in the water tank 161 through the conduit 163 and absorbed. After the recycling process is completed, the valve is opened to discharge the water from the drain pipe 164, which improves the convenience of dust treatment for this rice bran recycling device used in rice processing.

[0030] Further, the feeding mechanism 17 includes a feeding hopper 171 communicating with the feeding port 2. A blowing air pipe 172 is arranged at the top of the feeding hopper 171. A plurality of spray nozzles 173 are arranged on the inner circle of the blowing air pipe 172 and are inclined towards the feeding port 2. One end of the blowing air pipe 172 is interconnected with a connecting pipe 174, and the connecting pipe 174 communicates with the air inlet end of the fan 15. When adding rice bran, the feeding hopper 171 can be used to ensure smooth addition. At the same time, when the fan 15 is turned on, air is blown into the blowing air pipe 172 through the connecting pipe 174, and the air is sprayed out from the spray nozzles 173 around towards the feeding port 2 and blows towards the rice bran, avoiding the discharge of dust and facilitating the rapid entry of the rice bran into the processing box 1 for treatment and recycling.

[0031] Working principle: When using this rice bran recycling device for rice processing, the rice bran that needs to separate dust is introduced into the inclined guide plate 4 in the processing box 1 from the feeding port 2 after being processed by the feeding mechanism 17. At the same time, the motor 8 is turned on, and the rotating plate 9 is used to move the connecting plate 10 and the connecting rod 6 upwards, and then in cooperation with the groove 5 and the rotating shaft 7, the inclined guide plate 4 is reversed. The rotating plate 9 disengages from the connecting plate 10, and with the pulling force of the spring 11, the connecting rod 6 impacts the bottom of the processing box 1 to cause the inclined guide plate 4 to vibrate, so that the rice bran is laid flat and passes through a plurality of inclined guide plates 4. And under the action of the vibration force, the dust is lifted. Then, the fan 15 is turned on, and the dust is blown into the dust suction slot 14 by the air evenly blown out through the air blowing holes 13 and is processed by the dust suction mechanism 16, solving the problem that it is difficult for the existing rice bran recycling device to quickly remove the dust inside the rice bran.
