[0026] The following is combined Figures 1-2 This invention describes a rice husk steaming device, comprising a frame body 10, a rice husk silo 20, a steam conveying pipe 50, an exhaust pipe 30, and a blower pipe 70. The rice husk silo 20 is mounted on the frame body 10, with an inlet 21 at the top and an outlet at the bottom. A steam inlet is located at the bottom of the rice husk silo 20, and the steam conveying pipe 50 is connected to the steam inlet to deliver steam into the rice husk silo 20. The exhaust pipe 30 is connected to the rice husk silo 20 and is used to discharge gas from the rice husk silo 20. The blower pipe 70 is mounted on the frame, with its outlet located on the rice husk silo 20 and near the outlet. The rice husks need to be steamed to reduce the impact of impurities on the quality of the liquor. In this embodiment, the rice husks are stored in the rice husk silo 20 and steamed by introducing steam from the bottom, thereby realizing the steaming operation of the rice husks. During feeding, the air cannon pipe 70 is used to avoid clogging of the discharge port and improve the smoothness of feeding.

[0027] Specifically, the husk silo 20 is used to store husk material. It has a cylindrical structure and a sealed lid at the top. An inlet 21 is located on the lid. During feeding, the inlet 21 is opened to allow material to enter the husk silo 20. During steaming, the inlet 21 is closed, creating a relatively sealed space within the husk silo 20 to prevent steam leakage. The steam inlet is located near the outlet at the bottom of the husk, allowing steam to flow upwards, increasing the contact time between the husk and steam and improving steam utilization.

[0028] Specifically, the main frame 10 is equipped with multiple husk bins 20, which are arranged side by side. To achieve the steaming of a large quantity of husks at once, this embodiment can provide multiple husk bins 20 on the main frame 10, thereby completing the steaming of a large quantity of husks simultaneously, achieving large-scale husk steaming processing, and improving steaming efficiency. Figure 1 As shown, two husk bins 20 are provided on the main frame 10. The two husk bins 20 are arranged side by side, so that they can steam a large amount of material at one time.

[0029] Understandably, the rice husks will inevitably clump together after steam cleaning, which increases the risk of clumping at the discharge port. The blower pipe 70 is connected to a gas compressor at one end, which generates pulsed high-pressure gas. The other end of the blower pipe 70 extends into the rice husk silo 20, close to the discharge port. This allows the high-pressure pulsed gas to be directed towards the discharge port through the blower pipe 70, thus breaking up the material and effectively preventing blockage at the discharge port.

[0030] The main frame 10 is an integral frame structure used to support all components. A steam generator is connected to the input end of the steam delivery pipeline 50, and a steam inlet is connected to the output end of the steam delivery pipeline 50. The steam generator produces steam and continuously delivers it to the husk silo 20 through the steam delivery pipeline 50 to achieve steaming of the husk material. Specifically, the steam inlet is located near the discharge point, and can be positioned below the discharge port, allowing steam to steam from bottom to top, increasing the contact time between the husk material and the steam, thereby improving steam utilization efficiency.

[0031] In some embodiments, the rice husk steaming apparatus further includes a cooling system, which includes cooling pipes connected to the rice husk silo 20. The cooling pipes are used to cool the material inside the rice husk silo 20. During the steaming process, the material is heated to a high temperature, which is not conducive to subsequent processes. In this embodiment, the cooling system achieves cooling inside the rice husk silo 20, thereby improving cooling efficiency.

[0032] Specifically, the cooling system can be a variety of cooling methods, such as an air-cooled system or a liquid-cooled system, or a combination of air-cooled and liquid-cooled systems to improve cooling efficiency.

[0033] In conjunction with the above embodiments, an air-cooling system is selected for cooling. The cooling pipeline includes an air outlet duct 90 and a cold air delivery duct. The air outlet duct 90 is connected to the cold air delivery duct and is located inside the rice husk silo 20. The air outlet duct 90 has honeycomb-shaped air outlet holes. The rice husk is a granular material that is heated after steaming. In this embodiment, the air outlet duct 90 allows cooling air to be sprayed out and fully contact the rice husk, thereby achieving efficient cooling of the rice husk and improving cooling efficiency.

[0034] Specifically, the diameter of the air outlet is smaller than the minimum particle size of the rice husk, which prevents the rice husk from clogging the outlet. Furthermore, the rice husk forms numerous small gaps during storage and steaming, allowing cooling air to continuously flow through the outlet and remove heat from the inside of the rice husk silo 20, achieving efficient cooling. This air-cooling system also helps maintain the fluffiness of the rice husk accumulation, facilitating discharge and preventing blockages.

[0035] Understandably, the cold air delivery pipe is connected to an air cooler, which generates cold air and delivers it to the husk silo 20 through the cold air delivery pipe to cool the inside of the husk silo 20. Moreover, the cold air generated by the air cooler is pressurized, which can be ejected through the air outlet, preventing the air outlet from being blocked and maintaining the fluffiness of the stacked husks.

[0036] In some embodiments, the rice husk steaming device also includes a drain pipe 80, which is located at the bottom of the rice husk silo 20 and connected to the rice husk silo 20 for draining condensate. After the rice husks are steamed, cooling is required, which will generate condensate. In this embodiment, the drain pipe 80 enables continuous drainage of condensate, preventing condensate accumulation.

[0037] Specifically, the bottom of the husk silo 20 is equipped with a drain outlet, and a drain pipe 80 is connected to the drain outlet. Condensate and other liquids flow into the bottom of the husk silo 20 and are discharged through the drain outlet. Specifically, a suction pump is installed on the drain pipe 80, which can suck up the condensate and achieve rapid discharge of the condensate.

[0038] In some embodiments, the bottom of the husk silo 20 is also connected to an observation chamber 60, and the top of the observation chamber 60 is provided with a transparent observation window 61. During the steaming process, it is necessary to check the steaming status. In this embodiment, the observation window 61 facilitates real-time observation, thereby improving the steaming quality.

[0039] Specifically, the observation chamber 60 is a solid enclosed chamber structure located below the discharge port. An electrically controlled gate 62 is also installed on the observation chamber 60, used to open or close the discharge port. That is, the drive device 42 and the leading component of the electrically controlled gate 62 are located on the observation chamber 60, and a transparent observation window 61 is provided at the top of the observation chamber 60, thereby enabling real-time observation of the material's steaming status.

[0040] In some embodiments, the top of the husk silo 20 is also provided with a leveling mechanism 40, which is used for leveling the material. The material is added through the feed inlet 21 and gradually accumulates in the husk silo 20, which can cause the top of the accumulation to be uneven. In this embodiment, the leveling mechanism 40 is set to achieve leveling, and the leveling can ensure that the material is in full contact with the steam, and can also prevent uneven discharge in the later stage.

[0041] Specifically, the leveling mechanism 40 includes a rotating blade 41, which is located at the top of the husk silo 20 and connected to a drive device 42. The drive device 42 can drive the rotating blade 41 to rotate, thereby leveling the material during the rotation of the rotating blade 41. Specifically, during the material addition process, husks are continuously fed in through the feed inlet 21, and the husks gradually accumulate in the husk silo 20, forming a "tower-like" pile shape. After accumulating to the top of the husk silo 20, the leveling mechanism 40 rotates to achieve the leveling of the pile.

[0042] In a specific embodiment, one end of the exhaust pipe 30 is connected to the husk silo 20, and the other end of the exhaust pipe 30 is equipped with an exhaust fan 31, which is used to extract gas from the husk silo 20. During the steaming process inside the husk silo 20, the internal air pressure will gradually increase. In this embodiment, the exhaust pipe 30 can be used to exhaust gas in a timely manner, avoiding excessive pressure inside the husk silo 20, and can also accelerate the flow of gas during the cooling process, thereby improving cooling efficiency.

[0043] Specifically, during the steaming process, the pressure inside the husk silo 20 gradually increases, and the steam gradually cools down as it moves from bottom to top, which affects the overall steam utilization efficiency. In this embodiment, the exhaust pipe 30 enables timely discharge of gas from the top space, thereby preventing excessive pressure inside the husk silo 20 and ensuring continuous heating of high-temperature steam, thus improving steam efficiency.

[0044] It is understandable that by installing an exhaust fan 31 at the end of the exhaust duct, the internal gas can be discharged more quickly, thereby improving steam efficiency.

[0045] In a specific implementation, the bottom of the husk silo 20 is equipped with a screw feeding mechanism (not shown in the figure). The screw feeding mechanism is located below the discharge port to realize the conveying of the discharged material. After the material is steamed and cooled, it needs to be discharged and conveyed. In this embodiment, the screw feeding mechanism can realize the stable conveying of the material and can prevent blockage during the material conveying process to a certain extent.

[0046] It is understandable that rice husks tend to clump together after steaming. This embodiment uses a spiral feeding mechanism to achieve stable material transport and prevent further clumping of rice husks to a certain extent.

[0047] According to some embodiments provided by this utility model, level sensors are provided at both the top and bottom of the husk silo 20. The level sensors can sense the position of the material inside the husk silo 20, thereby enabling automated feeding and discharging operations.

[0048] In conjunction with the above embodiments, the rice husk steaming device of this utility model also includes a control system, a level sensor communicatively connected to the control system, and the control system capable of controlling the input and output of materials, the input and stop of steam, the opening and stopping of the exhaust pipe, and the opening and stopping of the air cannon pipe 70. The level sensor located at the top of the rice husk silo 20 is an upper level sensor 22, and the level sensor located at the bottom of the rice husk silo 20 is a lower level sensor. The specific control method includes the following steps:

[0049] Initially, rice husks fall into the rice husk silo 20 through the feed inlet 21 via a continuous automated conveying system. When the material level sensor 22 detects the presence of rice husks, the sensor outputs a signal to the control system (such as a PLC controller) to stop the conveying of rice husks. At this time, the rice husks accumulate to the top of the rice husk silo 20. The leveling mechanism 40, controlled by the control system, levels the rice husks in the rice husk silo 20 to prevent uneven subsequent discharge.

[0050] After the above process is completed, the control system outputs a control signal to send high-temperature steam through the steam delivery pipeline 50 into the rice husk silo 20, thereby continuously steaming the rice husks inside the silo 20. During the steaming process, the high-temperature steam is injected from the bottom of the rice husk silo 20 and rises to the top, gradually increasing the pressure. At this time, the control system outputs a signal to start the exhaust fan 31, continuously venting the rice husk odor contained in the high-temperature steam inside the rice husk silo 20. This achieves the functions of high-temperature sterilization and odor elimination of the rice husks, balances the internal pressure, and increases the steam flow rate. Throughout the entire process, the rice husk silo 20 is kept completely sealed to prevent steam and odor from escaping and affecting the on-site construction environment. An observation chamber 60 at the bottom of the rice husk silo 20 allows for manual observation of the rice husks during the steaming process.

[0051] After the above process is completed, the rice husks in the rice husk silo 20 need to be cooled. At this time, the control system outputs a control signal to start the cooling system and delivers cold air through the cold air delivery pipe to cool the rice husks. At the same time, the exhaust fan 31 continues to vent the residual heat steam in the rice husk silo 20. During the entire cooling process, the steam condensate will seep through the rice husks into the bottom of the rice husk silo 20. When the condensate accumulates at the bottom of the rice husk silo 20, the control system outputs a control signal to open the drain pipe outlet and drain the accumulated condensate.

[0052] After the above process is completed, once the rice husks have completely cooled and the moisture has been filtered out, the control system outputs a signal to open the gate at the discharge port, allowing the rice husks in the rice husk silo 20 to be conveyed by the screw conveyor. If, during the conveying process, the rice husks clump together and cause blockage, multiple air jets located at the bottom of the rice husk silo 20 near the discharge port will intermittently deliver high-pressure air through the air jet pipes to break up the clumps, thus clearing the blockages and ensuring continuous discharge of rice husks. During the rice husk discharge process, if the discharge level sensor at the bottom of the rice husk silo 20 detects no rice husk material, it sends a signal to the control system, stopping the rice husk discharge and initiating the reloading process. Repeating these steps completes the rice husk steaming process.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
