Description

Technical Field

[0001] This utility model specifically relates to a rice desiccant device, belonging to the field of rice processing technology. Background Technology

[0002] In the rice processing process, from hulling paddy to producing finished rice, it is necessary to go through many processes such as cleaning, hulling, and milling. However, even after multiple rounds of processing, the surface of finished rice is still easily covered with impurities such as rice bran fragments and fine debris. These impurities not only affect the appearance and color of the rice, but may also reduce the shelf life and taste of the rice due to carrying microorganisms or odors.

[0003] Due to the tendency for impurities to remain on the surface of processed rice, rice desiccant devices have been developed to improve the cleanliness of rice surfaces. These devices are mainly used in the final stage of rice processing to peel off and separate rice bran fragments and fine debris adhering to the surface of finished rice, in order to meet the quality requirements of subsequent packaging, sales, or further processing.

[0004] In the practical application of existing rice husk removal devices, after the removal of impurities from the rice surface is completed, an external bran suction fan is usually used. The negative pressure airflow generated by the fan is used to promptly remove the removed rice bran fragments and fine dust to prevent impurities from re-adhering to the rice surface. However, the negative pressure airflow generated by the bran suction fan alone is insufficient to penetrate deeply into the rice pile, resulting in incomplete adsorption of the fragments inside the rice. Consequently, the fragments end up mixed with the rice, which not only leads to low husk removal efficiency, failing to meet the needs of large-scale continuous production, but also results in a high level of impurity residue, which worsens the separation effect between rice and impurities, ultimately affecting the quality of the finished rice product. Therefore, this application provides a rice husk removal device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a rice husk removal device to improve husk removal efficiency and husk separation efficiency.

[0006] To further achieve the above objectives, the following technical solution is adopted: A rice husk removal device includes a frame, a connecting frame fixedly connected to one side of the frame, a feed inlet at the top of the frame, a husk removal box fixedly connected inside the frame, the bottom of the feed inlet being fixedly connected to the top of the husk removal box, a stirring mechanism for removing rice husks installed inside the husk removal box, two filter plates arranged inclined from top to bottom inside the frame, an extraction mechanism for adsorbing husks installed on one side of the frame, an air blowing mechanism for secondary husk separation installed inside the connecting frame, a discharge port at the bottom of the husk removal box, a valve installed in the discharge port, and air inlets symmetrically opened on the side of the frame opposite to the extraction mechanism, each air inlet having a filter plate fixedly connected to it.

[0007] Preferably, the extraction mechanism includes a collection box fixedly connected to one side of the frame, a straw suction fan fixedly connected to one side of the collection box, an exhaust pipe fixedly connected to the output end of the straw suction fan through a three-way pipe, and dust suction hoods symmetrically fixedly connected to one side of the inside of the frame. The ends of the two exhaust pipes away from the three-way pipe are respectively fixedly connected to the two dust suction hoods.

[0008] Preferably, a second filter plate is fixedly connected inside the collection box, a box door is provided on one side of the collection box, and the two dust collection hoods are respectively located above the two first filter plates.

[0009] Preferably, a vibration motor is fixedly connected to the bottom surface of each of the two filter plates, and a through groove is symmetrically opened on the connecting surface of the frame and the connecting frame. The two through grooves are respectively located above one end of the two filter plates, and the bottom wall of the through groove is flush with the upper surface of the corresponding filter plate.

[0010] Preferably, the blowing mechanism includes a baffle fixedly connected inside the connecting frame, which divides the interior of the connecting frame into a finished product area and a lint removal area. The finished product area and the lint removal area are in continuous communication with the outside. A fixed frame is symmetrically fixedly connected to the side of the connecting frame near the machine frame. The two fixed frames are respectively located below two through slots. A blower is fixedly connected to one end of each of the two fixed frames. Multiple air nozzles are fixedly connected to one side of each of the two fixed frames. An arc-shaped baffle is symmetrically fixedly connected to the side of the connecting frame near the machine frame. The two arc-shaped baffles are respectively located above the side of the two through slots facing the connecting frame. The multiple air nozzles are all inclined.

[0011] Preferably, the stirring mechanism includes a connecting shaft rotatably connected to the center of the feed inlet, a plurality of connecting plates fixedly connected to the outer wall of the connecting shaft, a gear one fixedly connected to one end of the connecting shaft, a servo motor fixedly connected to one side of the frame, a gear two fixedly connected to the output end of the servo motor, and the gear one and gear two meshing with each other.

[0014] Beneficial effects: 1. This application includes an extraction mechanism, a filter plate, and a vibration motor. After the rice has undergone de-dusting in the de-dusting box, before it falls onto the surface of the filter plate through the discharge port, the negative pressure airflow generated by the de-dusting fan can promptly suck away the separated rice bran fragments and fine particles through the dust suction hood to prevent impurities from adhering to the surface of the rice. Subsequently, the rice will fall onto the filter plate. At this time, the vibration motor can be activated to drive the two filter plates to continuously vibrate. Through the vibration force and the filtration characteristics of the two filter plates, the fine particles will be separated from the rice again, thereby improving the separation effect of the rice surface debris and ensuring that the rice has a higher degree of cleanliness after the de-dusting process.

[0015] 2. This application is equipped with an air blowing mechanism. With the guidance of the two filter plates and the inclined surface and the shaking force, the rice that has undergone secondary de-dust removal is guided into the interior of the connecting frame. During the falling process, the air generated by the air nozzle 21 blows away the fine dust remaining inside the rice again, so that the fine dust enters the de-dust removal area, while the clean rice falls into the finished product area, thereby further improving the cleanliness of the rice.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0019] Please see Figure 1-6 As shown, a rice husk removal device includes a frame 1, a connecting frame 2 fixedly connected to one side of the frame 1, a feed inlet 3 at the top of the frame 1, a husk removal box 4 fixedly connected inside the frame 1, the bottom end of the feed inlet 3 being fixedly connected to the top end of the husk removal box 4, a stirring mechanism for removing rice husks installed inside the husk removal box 4, two filter plates 9 inclined from top to bottom inside the frame 1, a husk extraction mechanism for adsorbing husks installed on one side of the frame 1, and a husk separation mechanism for secondary husk separation installed inside the connecting frame 2. The blowing mechanism has a discharge port at the bottom of the dandruff box 4, and a valve is installed in the discharge port. Vibration motors 10 are fixedly connected to the bottom surfaces of the two filter plates 9. The connecting surfaces of the frame 1 and the connecting frame 2 are symmetrically provided with through grooves 18. The two through grooves 18 are located above one end of the two filter plates 9 respectively, and the bottom wall of the through groove 18 is flush with the upper surface of the corresponding filter plate 9. Air inlets are symmetrically provided on the side of the frame 1 opposite to the extraction mechanism. Filter plates 27 are fixedly connected to the two air inlets. Secondly, the stirring mechanism includes a connecting shaft 5 rotatably connected to the center of the feed inlet 3. Multiple connecting plates 6 are fixedly connected to the outer wall of the connecting shaft 5. A gear 24 is fixedly connected to one end of the connecting shaft 5. A servo motor 25 is fixedly connected to one side of the frame 1. A gear 26 is fixedly connected to the output end of the servo motor 25. Gear 24 and gear 26 mesh with each other. Multiple through holes 7 are evenly opened on the surface of the multiple connecting plates 6. Multiple protrusions 8 are evenly fixedly connected to both sides of the multiple connecting plates 6. A controller 23 is fixedly connected to one side of the frame 1. All electrical components in the device are electrically connected to the controller 23. A drawer is slidably installed inside the frame 1. The drawer is located below the two filter plates 9.

[0020] During processing, rice often retains some bran or small impurities on its surface. Therefore, to ensure the cleanliness of the rice, the rice can be poured into the de-dust box 4 through the feed inlet 3. Then, the servo motor 25 can be started to drive the gear 26 to rotate. Since the gear 26 is meshed with the gear 1 24, the rotation of the gear 26 will drive the gear 1 24 and the connecting shaft 5 to rotate together. This causes multiple connecting plates 6 to rotate continuously inside the de-dust box 4 to stir the rice. During the stirring process, the rice is stirred by the through-feed mechanism. The holes 7 and protrusions 8 enhance the contact and collision with the rice, thereby improving the turning effect of the rice and allowing impurities such as rice bran fragments and fine debris attached to the surface of the rice to be better removed. Then, the valve in the discharge port can be opened and the multiple connecting plates 6 can be rotated. As the multiple connecting plates 6 rotate, the rice and the removed rice bran fragments will move to the discharge port. Thus, through the opened discharge port, the rice and the removed rice bran fragments fall onto the filter plate 9, allowing the rice and debris inside the desiccant box 4 to fall onto the filter plate 9 in sequence. Simultaneously with opening the valve, the extraction mechanism is activated. This mechanism uses negative pressure airflow to remove rice bran fragments and fine debris before they fall onto the filter plate 9 due to gravity, preventing impurities from adhering to the rice surface. After the initial absorption of fine debris, the rice falls onto the filter plate 9. Some rice bran fragments remain attached, so the vibration motor 10 is activated to continuously vibrate the two filter plates 9. Through the vibration and the filtration characteristics of the two filter plates 9, the rice bran fragments are separated from the rice again and filtered to the bottom. Inside the drawer, because the two filter plates 9 are set at an angle, the vibration of the filter plates 9 will also drive the rice on the top surface to gradually enter the interior of the connecting frame 2 through the through groove 18. At this time, the blowing mechanism inside the connecting frame 2 will identify whether there are fine particles in the rice again, and separate the fine particles from the rice. In this way, by combining multiple methods, the separation effect of the rice surface particles can be significantly improved, ensuring that the rice has a higher cleanliness after the particle removal process. This achieves multi-stage separation of rice surface particles, effectively solving the problems of low particle removal efficiency and poor separation effect in the existing technology, and can meet the quality requirements of large-scale continuous production.

[0021] Reference Figure 1 , Figure 2 and Figure 4The extraction mechanism includes a collection box 11 fixedly connected to one side of the frame 1. A suction fan 12 is fixedly connected to one side of the collection box 11. The output end of the suction fan 12 is fixedly connected to an exhaust pipe 14 through a three-way pipe. Dust hoods 15 are symmetrically fixedly connected to one side of the inside of the frame 1. The ends of the two exhaust pipes 14 away from the three-way pipe are fixedly connected to the two dust hoods 15 respectively. A filter plate 16 is fixedly connected inside the collection box 11. A door is provided on one side of the collection box 11. The two dust hoods 15 are located above the two filter plates 9 respectively. Multiple exhaust ports are opened on the side of the collection box 11 away from the suction fan 12.

[0022] In use, the rice bran suction fan 12 can be started to generate negative pressure airflow, which is transmitted to the two dust suction hoods 15 through the three-way pipe and two exhaust pipes 14. Since the two dust suction hoods 15 are located above the two filter plates 9, when the rice is de-dusted inside the de-dust box 4 and the discharge valve is opened to fall, and before the fine crumbs and rice fall onto the surface of the filter plates 9 due to gravity, the de-dust can be sucked away by the dust suction hoods 15 in time through the negative pressure airflow and guided into the collection box 11. The fine crumbs guided into the collection box 11 will be blocked by the filter plate 16, so that the fine crumbs will not flow backward with the airflow and be intercepted inside the collection box 11. At the same time, the filtered air is discharged to the outside through the exhaust port to prevent impurities from adhering to the surface of the rice again. When a certain amount of fine crumbs are collected inside the collection box 11, the box door can be opened to clean the fine crumbs.

[0023] Reference Figure 1 , Figure 2 and Figure 5 The blowing mechanism includes a baffle 17 fixedly connected inside the connecting frame 2. The baffle 17 divides the interior of the connecting frame 2 into a finished product area and a lint removal area. The finished product area and the lint removal area are connected to the outside. A fixed frame 19 is symmetrically fixedly connected inside the connecting frame 2 on the side near the machine frame 1. The two fixed frames 19 are located below the two through slots 18 respectively. A blower 20 is fixedly connected to one end of each of the two fixed frames 19. Multiple air nozzles 21 are fixedly connected to one side of each of the two fixed frames 19. An arc-shaped baffle 22 is symmetrically fixedly connected inside the connecting frame 2 on the side near the machine frame 1. The two arc-shaped baffles 22 are located above the side of the two through slots facing the connecting frame 2 respectively. The multiple air nozzles 21 are all inclined.

[0024] During use, guided by the inclined surfaces of the two filter plates 9 and the vibration force, the rice that has undergone secondary lint removal is guided into the interior of the connecting frame 2. Then, due to gravity, the rice gradually falls into the finished product area. During this descent, the controller 23 controls the corresponding blower 20 to generate airflow. This airflow is then transmitted through the fixing frame 19 to multiple air nozzles 21, and ejected through these nozzles. The airflow generated by the nozzles 21 further blows away any remaining fine particles inside the rice during the descent, causing them to enter the lint removal area. The clean rice falls into the finished product area, further improving the cleanliness of the rice. The baffle 17 divides the inside of the connecting frame 2 into a finished product area and a lint removal area, which can prevent the fine lint generated during the lint removal process from contaminating the rice in the finished product area, thus ensuring the quality of the rice. At the same time, the arc-shaped baffle and the multiple air inlets on one side of the frame 1 can reduce the suction and airflow generated inside the frame 1, thereby preventing airflow chaos inside the frame 1. Meanwhile, multiple air nozzles 21 are tilted downwards to allow the fine lint to move normally to the lint removal area during the secondary lint removal.

[0025] As a technical optimization of this utility model: First, the rice to be de-dusted can be poured into the de-dusting box 4 through the feed port 3. Then, the servo motor 25 can be started to drive the gear 26 to rotate. Since the gear 26 meshes with the gear 1 24, the rotation of the gear 26 can drive the gear 1 24 and the connecting shaft 5 to rotate together. This allows the multiple connecting plates 6 to rotate continuously inside the de-dusting box 4 to stir the de-dusting box 4. During the stirring process, the through hole 7 and the protrusion 8 can enhance the contact and collision with the rice, thereby improving the turning effect of the rice. This allows the rice bran fragments, fine debris and other impurities attached to the surface of the rice to be better peeled off. Then, the valve in the discharge port can be opened and the multiple connecting plates 6 can continue to rotate. As the multiple connecting plates 6 rotate, the rice and the peeled rice bran fragments will move to the discharge port. This allows the rice and the peeled rice bran fragments to fall onto the filter plate 9 through the opened discharge port, so that the rice and debris inside the de-dusting box 4 can fall onto the filter plate 9 in sequence. Simultaneously with opening the valve, the rice bran suction fan 12 is activated to generate negative pressure airflow. This airflow is transmitted through the three-way pipe and two exhaust pipes 14 to the two dust suction hoods 15. Since the two dust suction hoods 15 are located above the two filter plates 9, when the rice is de-dusted inside the de-dusting box 4 and falls through the discharge valve, before the fine rice and rice fall onto the surface of the filter plates 9 due to gravity, the negative pressure airflow can promptly suck away the separated rice bran fragments and fine particles through the dust suction hoods 15 and guide them into the collection box 11. At the same time, the filtered air is discharged to the outside through the exhaust port. After the initial absorption of fine particles, the rice will fall onto the filter plates 9. At this time, some rice bran fragments still attached to the rice will not be absorbed. Therefore, the vibration motor 10 can be activated to drive the two filter plates 9 to continuously vibrate. Through the vibration force and the filtration characteristics of the two filter plates 9, the rice bran fragments will be removed. The rice is separated from the main rice and filtered into the bottom drawer. Because the two filter plates 9 are tilted, the vibration of the filter plates 9 causes the rice on the top surface to gradually pass through the through-slot 18 into the connecting frame 2. At this point, due to gravity, the rice gradually falls into the finished product area. During this fall, the controller 23 controls the corresponding blower 20 to generate airflow. The airflow is then transmitted through the fixing frame 19 to multiple air nozzles 21 and ejected through the nozzles. The airflow from the nozzles 21 further blows away any remaining fine particles from the falling rice, causing them to enter the de-dust removal area. The clean rice then falls into the finished product area, further improving the cleanliness of the rice. Furthermore, the baffle 17 divides the interior of the connecting frame 2 into a finished product area and a de-dust removal area, preventing fine particles generated during the de-dust removal process from contaminating the rice in the finished product area and ensuring the quality of the rice.
