Description

Technical Field

[0001] This utility model relates to the field of rice bran steaming machine technology, and in particular to a rice bran steaming machine cleaning structure and rice bran steaming machine. Background Technology

[0002] There are two main processes for rice husk cooking: continuous production and discontinuous production. The former has a large output and high production efficiency, and the main equipment is a tunnel-type rice husk steamer, while some use a cooking tower-type rice husk steamer. The latter has a smaller output and lower production efficiency, and usually uses a still with water added to the bottom pot for steaming, or a tanker truck for steaming.

[0003] With the increasing use of tunnel-type rice husk steaming machines (also known as continuous rice husk steaming machines) in wineries, the processing capacity of rice husks has been greatly improved, but there are still many shortcomings in the production process. The main structure of existing tunnel-type rice husk steaming machines is largely the same, consisting of two parts: a steaming section and a cooling section. The steaming section consists of a set of rotating chain plates or roller-driven steel belts, a steaming section frame, a feed hopper, a tunnel-type box, a steaming chamber, steam piping components, and drainage piping components. The cooling section consists of a set of rotating chain plates or roller-driven steel belts, a cooling section frame, an exhaust hood, a tunnel-type box, a cooling chamber, and a discharge hopper.

[0004] To ensure that the rice husks in the tunnel-type container are fully steamed or cooled, the chain plates or steel belts carrying the rice husks must be perforated. In actual production, a certain amount of rice husks will inevitably fall through the mesh into the steaming and cooling chambers. If too much material accumulates in the steaming chamber or if it remains for too long, it will mold and carbonize, making it difficult to clean. One of the purposes of steaming rice husks is to remove any unpleasant odors from them. If the material in the steaming chamber becomes moldy, its musty smell will be transferred to the rice husks in the tunnel-type container above the mesh belt through the steam, reducing the quality of the steamed rice husks. If too much material accumulates in the cooling chamber, it will affect the air delivery surface and cooling effect of the centrifugal fan in the cooling chamber, resulting in a longer dehumidification and cooling time for the finished rice husks, thus affecting the yield.

[0050] Example 1

[0051] like Figure 1-13 As shown, a material cleaning structure for a rice bran steamer includes: a steaming chamber cleaning mechanism 1 and a cooling chamber cleaning mechanism 2. The steaming chamber cleaning mechanism 1 includes: a first driving device 101, a first scraper 102, and a first discharge device 103. The first driving device 101 is installed in the steaming chamber 3, and a first discharge position 301 is provided at the bottom of the steaming chamber 3. The first scraper 102 is connected to the first driving device 101 and is used to push the material at the bottom of the steaming chamber 3 toward the first discharge position 301. The first discharge device 103 is connected to the first discharge position 301. 103 is used to send the material out of the cooking chamber 3. The cooling chamber cleaning mechanism 2 includes: a second drive device 201, a second scraper 202, and a second discharge device 203. The second drive device 201 is installed in the cooling chamber 4. A second discharge position 401 is arranged at the bottom of the cooling chamber 4. The second scraper 202 is connected to the second drive device 201. The second scraper 202 is used to push the material at the bottom of the cooling chamber 4 toward the second discharge position 401. The second discharge device 203 is connected to the second discharge position 401. The second discharge device 203 is used to send the material out of the cooling chamber 4.

[0052] Specifically, such as Figure 4 , 10 As shown, the first drive device 101 drives the first scraper 102 to rotate at the bottom of the cooking chamber 3, and the second drive device 201 drives the second scraper 202 to rotate at the bottom of the cooling chamber 4. The rotation of the first scraper 102 pushes the material to the first discharge position 301, and the rotation of the second scraper 202 pushes the material to the second discharge position 401.

[0053] Specifically, such as Figure 4 , 10 As shown, both the first drive device 101 and the second drive device 201 are chain drive devices driven by electric motors. In the first drive device 101, the sprocket is rotatably mounted at the bottom of the cooking chamber 3, driven by an electric motor, with a chain wound around it. Multiple first scrapers 102 are evenly distributed along the length of the chain. In the second drive device 201, the sprocket is rotatably mounted at the bottom of the cooling chamber 4, driven by an electric motor, with a chain wound around it. Multiple second scrapers 202 are evenly distributed along the length of the chain.

[0054] Specifically, such as Figure 13 As shown, the cooking chamber cleaning mechanism 1 further includes: a first support frame 104, which is connected to the cooking chamber 3 and supports the chain. Since the chain is relatively long, supporting it with the first support frame 104 improves the stability of the chain's movement. The first scraper 102 has first extending edges on both sides, extending above the first support frame 104. The cooling chamber cleaning mechanism 2 further includes: a second support frame, which is connected to the cooling chamber 4 and supports the chain. Since the chain is relatively long, supporting it with the second support frame improves the stability of the chain's movement. The second scraper 202 has second extending edges on both sides, extending above the second support frame. The first extending edges facilitate scraping away material falling onto the first support frame 104, and the second extending edges facilitate scraping away material falling onto the second support frame, thereby reducing the material residue rate.

[0055] Specifically, such as Figure 13 As shown, the chain plate extends into a connecting plate. The first scraper 102 is connected to the connecting plate by bolts, so that the first scraper 102 is detachably connected to the first drive device 101. The second scraper 202 forms a detachable connection structure with the second drive device 201 through the same structure, thereby facilitating the later maintenance of the first scraper 102 and the second scraper 202.

[0056] Specifically, the first scraper 102 and the second scraper 202 are made of non-metallic elastic wear-resistant materials, such as rubber sheets, to improve the service life of the first scraper 102 and the second scraper 202.

[0057] Specifically, such as Figure 7 , 10 As shown, the first discharge position 301 and the second discharge position 401 are grooves located at the bottom of the cooking chamber 3 and the cooling chamber 4, respectively. Both the first discharge device 103 and the second discharge device 203 are screw conveyors. The cleaning augers of the first discharge device 103 and the second discharge device 203 are rotatably set in the first discharge position 301 or the second discharge position 401. The material in the groove is sent out to the outside of the cooking chamber 3 through the first discharge position 301, and the material in the groove is sent out to the outside of the cooling chamber 4 through the second discharge device 203. The first discharge device 103 and the second discharge device 203 are not limited to screw conveyors, but can also use conveying equipment such as tubular chain conveyors. The discharge port of the first discharge device 103 is equipped with an impeller unloader. The impeller unloader improves the sealing effect of the discharge port and prevents steam from leaking out of the cooking chamber 3.

[0058] Specifically, such as Figure 3 , 5As shown in Figure 9, the material cleaning structure of the rice bran steamer also includes: a receiving tray 5 and a receiving tray cleaning mechanism 6. The receiving tray 5 is located directly below the discharge hopper 7, the cooking chamber 3, and the cooling chamber 4 of the rice bran steamer. The receiving tray cleaning mechanism 6 is connected to the receiving tray 5 and is used to deliver the material out of the receiving tray 5. The receiving tray cleaning mechanism 6 facilitates the removal of material from the rice bran steamer, thereby reducing the intensity of manual labor.

[0059] Specifically, such as Figure 3 , 8 As shown, the receiving tray 5 is connected to the frame 8 of the rice bran steamer. The receiving tray cleaning mechanism 6 includes a third drive device 601, a third scraper 602, and a third discharge device 603. The third drive device 601 is connected to the receiving tray 5, which has a third discharge position 501. The third scraper 602 is connected to the third drive device 601 and is used to push the material in the receiving tray 5 to the third discharge position 501. The mechanized feeding operation is achieved through the cooperation of the third drive device 601, the third scraper 602, and the third discharge device 603.

[0060] Specifically, such as Figure 5 , 9 As shown, the third drive device 601 adopts a chain drive device, which is driven by a motor. The sprocket of the chain drive device is rotatably connected to both ends of the receiving tray 5. Chain guide rails are connected to both sides of the receiving tray 5. The chain is wound around the sprocket and connected to both sides of the receiving tray 5 through the chain guide rails. The third scraper 602 is connected to the chain. The third drive device 601 is used to drive the third scraper 602 to rotate or reciprocate, thereby pushing the material in the receiving tray 5 to the third discharge position 501 through the third scraper 602.

[0061] Specifically, the third scraper 602 is connected to the connecting plate extending from the chain plate in the chain by bolts. When the third scraper 602 is connected above and below the chain, the chain drives the third scraper 602 to rotate. When the third scraper 602 is set between the chains, the chain drives the third scraper 602 to reciprocate.

[0062] Specifically, such as Figure 5 , 9As shown, when the third scraper 602 reciprocates, the receiving tray cleaning mechanism 6 further includes: a first position sensor 604 and a first position sensor 605. The first position sensor 604 and the first position sensor 605 are limit switches. The first position sensor 604 and the first position sensor 605 are connected to the controller's electrical control signal. The controller is connected to the motor's electrical control signal in the third drive device 601. The first position sensor 604 is located at one end of the receiving tray 5 at the third discharge position 501, and the first position sensor 605 is located at the other end of the receiving tray 5. The first position sensor 604 and the first position sensor 605 are used to control the scraper's extreme movement position in the receiving tray 5. When the first position sensor 604 and the first position sensor 605 detect the third scraper 602, the motor reverses, and the third scraper 602 moves stably in the receiving tray 5 under the control of the first position sensor 604 and the first position sensor 605.

[0063] Specifically, such as Figure 12 The impeller unloader (airlocker) shown is equipped with a waste bin at its discharge port. The waste bin collects the material cleaned from the cooking chamber 3. The second discharge position 401 is also connected to an inclined chute 204. The discharge port of the inclined chute 204 is located in the receiving tray 5. The discharge from the inclined chute 204 is cleaned by the receiving tray cleaning mechanism 6.

[0064] The working principle of the material cleaning structure of this type of steaming rice bran machine is as follows: The first drive device 101 drives the first scraper 102 to move, pushing the material that falls to the bottom of the cooking chamber 3 to the first discharge position 301, and the first discharge device 103 conveys the material to the waste bin; the second drive device 201 drives the second scraper 202 to move, pushing the material that falls to the bottom of the cooling chamber 4 to the second discharge position 401, and the second discharge device 203 conveys the material to the receiving tray 5; the third drive device 601 drives the third scraper 602 to push the material in the receiving tray 5 to the third discharge position 501, and the third discharge device 603 sends the material out to the next stage.
