Description

Technical Field

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

[0002] Rice, also known as paddy rice, is a food made from paddy rice through processes such as cleaning, hulling, milling, and finishing. Before processing and packaging, rice often needs to undergo impurity removal to ensure that it can be consumed normally and to guarantee the quality of rice processing.

[0003] Existing rice processing impurity removal devices have significant drawbacks when handling large-scale raw materials. In actual production, to improve processing efficiency, a large amount of rice is typically fed into the equipment at once for uniform vibration and impurity removal filtration. However, because the rice accumulates to a considerable depth within the equipment, the vibration force generated by the screen is difficult to evenly distribute to the interior of the raw material. This results in impurities located deep within the rice not being effectively driven towards the screen, easily accumulating inside the raw material and affecting the impurity removal effect. Therefore, this paper proposes a rice processing impurity removal device to address these problems. Utility Model Content

[0022] 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 scope of protection of the present utility model.

[0023] Please see Figure 1-5 As shown, a rice processing impurity removal device includes a feeding box 1, a feeding hopper 2 fixedly connected to the bottom of the feeding box 1, a motor 3 fixedly connected to the top of the feeding box 1, a spiral conveying blade 4 fixedly connected to the drive end of the motor 3, an impurity removal cylinder 5 installed at the bottom of the feeding hopper 2, the impurity removal cylinder 5 including a fixed cylinder 51 and a rotating cylinder 52 rotatably connected, the upper surface of the fixed cylinder 51 being fixedly connected to the bottom of the feeding hopper 2, a conical channel being provided inside the fixed cylinder 51, and an impurity removal assembly 6 installed on the surface of the impurity removal cylinder 5, the impurity removal assembly 6 including a second motor 61 and an electric push rod 64, the second motor 61 being fixedly installed on the outer wall of the fixed cylinder 51. The drive end of the motor 61 is fixedly connected to a telescopic transmission cylinder 62, and the other end of the telescopic transmission cylinder 62 is fixedly connected to a connecting plate 63. The outer wall of the connecting plate 63 is slidably connected to the inner wall of the rotating cylinder 52. Specifically, the inner wall of the rotating cylinder 52 is provided with a groove, and the outer wall of the connecting plate 63 protrudes outward to form a slider. The slider is slidably connected to the groove. The rotating cylinder 52 includes a filter cylinder 521 with coarse filter holes and a side baffle 522. An electric push rod 64 is fixedly installed at the center of the side baffle 522, and the drive end of the electric push rod 64 extends into the interior of the telescopic transmission cylinder 62 and is rotatably connected to the inner wall of the telescopic transmission cylinder 62.

[0024] Specifically, the single feeding amount can be adjusted by controlling the speed and running time of motor 3. In use, rice is added into the feeding box 1 for storage. Then, motor 3 drives the spiral conveyor blades 4 to rotate and convey a certain amount of rice downwards before stopping. Thus, the spiral conveyor blades 4 can convey rice in batches, reducing the amount of rice per impurity removal, avoiding rice accumulation and improving the impurity removal effect. At the same time, it avoids rice blockage in the feeding hopper 2. The rice falls into the fixed cylinder 51 through the feeding hopper 2 and slides down the conical channel into the rotating cylinder 52. Motor 61 drives the telescopic transmission cylinder 62 to rotate, which drives the connecting plate 63 to rotate. The connecting plate 63 drives the filter cylinder 521 to rotate, and then the filter cylinder 521 rotates to remove impurities by rotating and screening the rice. The impurities in the rice are discharged through the coarse filter holes on the surface of the filter cylinder 521 under the action of centrifugal force.

[0025] A telescopic limiting rod 523 is fixedly connected to the outer wall of the side baffle 522, and the other end of the limiting rod 523 is fixedly connected to the outer wall of the fixed cylinder 51.

[0026] Specifically, the side baffle 522 and the electric push rod 64 are limited by the limiting rod 523 to prevent them from rotating. After the impurity removal is completed, the motor 61 is turned off and the electric push rod 64 is run. The electric push rod 64 extends and pushes the side baffle 522 to move away from the fixed cylinder 51, and drives the telescopic transmission cylinder 62 to extend. The extension of the telescopic transmission cylinder 62 drives the connecting plate 63 to move. The movement of the connecting plate 63 pushes the rice to fall out of the opening of the filter cylinder 521, realizing the automatic feeding of rice.

[0027] A collection cylinder 7 is provided on the outside of the impurity removal cylinder 5. One end of the collection cylinder 7 is fixedly connected to the outer wall of the fixed cylinder 51. A fan blade 8 is fixedly connected to the outer wall of the telescopic transmission cylinder 62. A filter chamber 9 is formed by the bottom of the collection cylinder 7 protruding downwards. An impurity collection assembly 10 is installed inside the filter chamber 9. The impurity collection assembly 10 includes a filter plate 101. The filter plate 101 is located at the bottom of the filter chamber 9. A receiving plate 12 is fixedly connected to the outer wall of the filter chamber 9 and is inclined downwards. The receiving plate 12 is used to collect the discharged rice.

[0028] Specifically, the telescopic transmission cylinder 62 rotates to drive the fan blade 8 to rotate. When the fan blade 8 rotates, it generates airflow that flows towards the rotating cylinder 52. The airflow can carry impurities through the coarse filter holes into the filter chamber 9, improving the filtration effect of impurities. After the airflow enters the filter chamber 9, it passes through the filter plate 101 to filter the impurities in the airflow, thereby intercepting the impurities in the filter chamber 9 and achieving the effect of filtering impurities, reducing the pollution of impurities to the air.

[0029] The filter plate 101 is L-shaped. The top of the filter plate 101 is fixedly connected to the lower side wall of the side baffle 522. Fine filter holes are opened in a local area on the surface of the filter plate 101. The coarse filter holes are larger than the fine filter holes. The size of the coarse filter holes is smaller than the rice and larger than the impurities. The size of the fine filter holes is smaller than the impurities.

[0030] Specifically, impurities in the airflow are filtered through fine filter holes. The filter plate 101 is connected to the side baffle 522. When the rotating cylinder 52 is closed, it drives the filter plate 101 to be inserted into the bottom of the filter chamber 9 for filtration. When the rotating cylinder 52 is opened, the filter plate 101 moves to the outside of the filter chamber 9, thereby opening the filter chamber 9 to discharge impurities.

[0031] The bottom of the filter chamber 9 is fixedly connected to an inclined baffle plate 11. The impurity collection assembly 10 also includes a collection chamber 102, which is fixedly installed at the bottom of the filter chamber 9. The collection chamber 102 is offset from the fine filter hole, and the bottom of the collection chamber 102 is inclined in the opposite direction to the inclination of the baffle plate 11.

[0032] Specifically, by adjusting the direction of airflow when it exits the filter chamber 9 through the baffle plate 11, so that it is opposite to the tilt direction of the bottom of the collection chamber 102, when the filter plate 101 moves outward, it intercepts the impurities above the filter plate 101 through the bottom end of the filter chamber 9, and after the filter plate 101 moves out of the filter chamber 9, the impurities fall into the collection chamber 102 and slide out from the inside of the collection chamber 102, realizing the automatic separation and collection of impurities, and avoiding excessive impurities from clogging the filter plate 101.

[0033] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires. Appropriate controllers should be selected based on actual conditions to electrically connect motor 3, motor 61, and electric actuator 64 to meet control requirements. Specific connections and control sequences should refer to the working principle described below, where the electrical connections are completed according to the sequential working order of each electrical component. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, without further explanation of electrical control.

[0034] The parts of the device not covered herein are the same as or can be implemented using existing technologies.

[0035] Working principle: During use, rice is added to the feed hopper 1 for storage. Then, motor 3 drives the spiral conveyor blades 4 to rotate and convey a certain amount of rice downwards before stopping. The height of the rice piled up in the filter cylinder 521 needs to be less than the height of the lowest point of the inner diameter of the connecting plate 63. This allows the spiral conveyor blades 4 to convey the rice in batches, reducing the amount of rice per impurity removal, avoiding rice accumulation and improving the impurity removal effect. At the same time, it prevents the rice from clogging in the feed hopper 2. The rice falls through the feed hopper 2 into the fixed cylinder 51 and slides down the conical channel into the rotating cylinder 52. Motor 61 drives the telescopic transmission cylinder. Rotating the telescopic transmission cylinder 62 causes the connecting plate 63 to rotate, which in turn causes the filter cylinder 521 to rotate. This allows the rice to be sieved and impurities removed through the filter cylinder 521. Under centrifugal force, impurities in the rice are discharged through the coarse filter holes on the surface of the filter cylinder 521. After impurity removal, the motor 61 is turned off, and the electric push rod 64 is activated. The electric push rod 64 extends and pushes the side baffle 522 to move away from the fixed cylinder 51, which in turn extends the telescopic transmission cylinder 62. The extension of the telescopic transmission cylinder 62 causes the connecting plate 63 to move, and the movement of the connecting plate 63 pushes the rice to fall out of the opening of the filter cylinder 521, thus achieving automatic rice feeding.

[0036] The rotation of the telescopic transmission cylinder 62 drives the fan blade 8 to rotate. When the fan blade 8 rotates, it generates airflow towards the rotating cylinder 52. The airflow can carry impurities through the coarse filter holes into the filter chamber 9, improving the filtration effect of impurities. After the airflow enters the filter chamber 9, it passes through the filter plate 101 to filter the impurities in the airflow, thereby intercepting the impurities in the filter chamber 9 and achieving the effect of filtering impurities, reducing the pollution of impurities to the air. When the rotating cylinder 52 is closed, it drives the filter plate 101 to insert into the bottom of the filter chamber 9 for filtration. When the rotating cylinder 52 is opened, the filter plate 101 moves to the outside of the filter chamber 9, thereby opening the filter chamber 9 to discharge impurities. When the filter plate 101 moves to the outside, it intercepts the impurities above the filter plate 101 through the bottom end of the filter chamber 9. After the filter plate 101 moves out of the filter chamber 9, the impurities fall into the collection chamber 102 and slide out from the inside of the collection chamber 102, realizing the automatic separation and collection of impurities and avoiding excessive impurities that cause the filter plate 101 to become clogged.

[0037] Several feeding plates 13 are fixedly connected to the inner wall of the filter cartridge 521.

[0038] Specifically, the feeding plate 13 is used to convey the rice from the bottom of the filter cylinder 521 upwards during rotation and drop it from a height, thereby improving the flowability of the rice and enhancing the impurity removal effect.
