Description

[0001] Soybean protein drying hot air flow equalization guide plate Technical Field

[0002] This utility model relates to the field of soybean processing technology, specifically to a hot air flow equalization guide plate for soybean protein drying. Background Technology

[0003] In the process of drying soybean protein, the uniform distribution of hot air is crucial to product quality. However, traditional air ducts are prone to uneven airflow, which affects the drying effect. Therefore, a hot air flow equalization guide plate for drying soybean protein is set up to redistribute the high-speed, uneven hot airflow, prevent airflow deviation, ensure that it acts evenly on the soybean protein, and improve drying efficiency and product quality.

[0004] The existing equipment still has the following shortcomings: Since most of the existing equipment has a fixed angle structure and lacks a dynamic adjustment mechanism, it is not convenient to adaptively adjust the air direction according to the real-time hot air flow and temperature changes when dealing with soybean protein materials with different moisture contents and particle sizes. This can easily create dead air zones in the drying tower, resulting in insufficient hot air scouring in some areas and affecting the uniformity and efficiency of soybean protein drying. Utility Model Content

[0005] This invention provides a hot air flow equalization guide plate for drying soybean protein, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] This utility model provides a hot air flow equalization guide plate for drying soybean protein, including a fixing frame, and further comprising:

[0008] A flow equalization plate is fixed inside a fixed frame, and a dust filter screen is installed on one side of the flow equalization plate;

[0009] A guide structure is provided on one side inside the fixed frame. The guide structure includes an air guide plate rotatably connected inside the outer frame, a swing arm fixed to the rotating end of one side of the air guide plate, and a transmission assembly provided on one side of the swing arm.

[0010] The cleaning structure, located on one side of the dust filter, is used to clean foreign objects from the surface of the dust filter.

[0011] Through the above technical solution, hot air enters the fixed frame and passes through a dust filter. The dust filter can intercept dust and impurities in the hot air to ensure the quality of soybean protein. Then, the hot air passes through the holes on the surface of the flow equalization plate. The flow rate and direction of the hot air are initially adjusted by the dense holes on the flow equalization plate to make the hot air distribution relatively uniform. Subsequently, the guide structure guides the hot air to prevent it from getting too hot.

[0012] Furthermore, an outer frame is fixed to the outside of the fixed frame, and a collection groove is fixed to one side inside the outer frame. A baffle connected to the outer frame is provided at the bottom of the collection groove.

[0013] The above technical solution uses a collection tank to collect dust and impurities swept off the cleaning structure, preventing foreign objects from being re-entrained and affecting the uniform flow of hot air. The baffle can be opened and closed freely, making it convenient to centrally clean the accumulated materials in the collection tank.

[0014] Furthermore, the transmission assembly includes a transmission frame rotatably connected to one side of the swing arm, a guide groove formed inside one side of the transmission frame, a stepper motor installed inside one side of the outer frame, and a cam installed at the end of the stepper motor output shaft and slidably connected to the guide groove.

[0015] The above technical solution uses a stepper motor to drive a cam to rotate, which in turn drives a swing arm through a transmission frame to rotate a guide plate. This adjusts the angle of the guide plate, thereby changing the direction and distribution of hot air and precisely directing the hot air to the area that needs drying, thus improving the uniformity and efficiency of soybean protein drying.

[0016] Furthermore, several groups of air guide plates are arranged inside the fixed frame, and the several groups of air guide plates are distributed at equal intervals inside the fixed frame.

[0017] By using the above technical solution, and by setting up several sets of air guide plates that are evenly distributed inside the fixed frame, the hot air can be guided in multiple directions and angles, so that the hot air is evenly distributed within the entire cross-sectional area of ​​the fixed frame, effectively avoiding local wind direction deviation or uneven airflow.

[0018] Furthermore, a cylindrical rod is provided on the top of one side of the cam, and the cam forms a sliding structure with the guide groove through the rod.

[0019] The above technical solution enables the rod to slide smoothly in the guide groove when the stepper motor drives the cam to rotate, accurately converting the cam's circular motion into the linear reciprocating motion of the transmission frame, thereby stably driving the swing arm and the air guide plate to rotate.

[0020] Furthermore, the cleaning structure includes a transmission rod rotatably connected to the top of the fixed frame, synchronous pulleys respectively installed on both sides of the transmission rod and the bottom of both sides of the fixed frame, a synchronous belt sleeved on the outside of the synchronous pulleys and connected to the cleaning brush, and a drive motor installed on the top of the fixed frame and connected to the output shaft end and the transmission rod.

[0021] The above technical solution involves a drive motor that drives a synchronous wheel to rotate via a transmission rod. This synchronous wheel then drives a cleaning brush via a synchronous belt. The cleaning brush removes dust and foreign objects from the surface of the filter screen, while a collection trough collects these foreign objects.

[0022] Furthermore, the cleaning brush extends to the outside of the fixed frame and connects to the transmission rod, and soft bristles are arranged at equal intervals on one side of the cleaning brush.

[0023] The above technical solution effectively removes foreign objects from the pores of the dust filter without damaging the filter structure, thus ensuring the cleaning effect and the service life of the dust filter to a certain extent.

[0024] The above-described solution of this utility model has at least the following beneficial effects:

[0025] 1. This utility model uses a stepper motor to drive a cam to rotate, which in turn drives a swing arm through a transmission frame to rotate a guide plate, thus adjusting the angle of the guide plate. This achieves the airflow adjustment function of the device, which can optimize the airflow direction in real time according to the material characteristics and hot air parameters during soybean protein drying. This avoids the airflow dead zone problem caused by the fixed guide plate, and ensures that the hot air evenly covers all areas of the drying tower, thereby improving the uniformity of soybean protein drying.

[0026] 2. This utility model uses a drive motor to drive a synchronous wheel to rotate via a transmission rod. The synchronous wheel then drives a cleaning brush via a synchronous belt to clean the surface of the dust filter. This achieves the dust filter cleaning function of the device, preventing dust accumulation from forming airflow resistance, ensuring long-term stability of airflow direction adjustment accuracy and flow uniformity efficiency, and reducing downtime caused by manual cleaning.

[0034] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0035] like Figures 1 to 5 As shown, an embodiment of this utility model provides a hot air flow equalization guide plate for drying soybean protein, including a fixing frame 1, and further comprising:

[0036] The flow equalization plate 8 is fixed inside the fixed frame 1, and a dust filter 2 is installed on one side of the flow equalization plate 8;

[0037] The guide structure 5 is set on one side inside the fixed frame 1. The guide structure 5 includes an air guide plate 501 rotatably connected inside the outer frame 4, a swing arm 504 fixed to the rotating end of one side of the air guide plate 501, and a transmission assembly set on one side of the swing arm 504.

[0038] Cleaning structure 3 is set on one side of the dust filter 2 and is used to clean foreign objects from the surface of the dust filter 2.

[0039] An outer frame 4 is fixed to the outside of the fixed frame 1, and a collection trough 7 is fixed to one side inside the outer frame 4. A baffle 6 connected to the outer frame 4 is provided at the bottom of the collection trough 7.

[0040] In this embodiment of the utility model, after the hot air enters the fixed frame 1, it passes through the dust filter 2. The dust filter 2 can intercept dust and impurities in the hot air to ensure the quality of soybean protein. Then the hot air passes through the holes on the surface of the flow equalization plate 8. The flow rate and direction of the hot air are initially adjusted by the dense holes on the flow equalization plate 8 to make the hot air distribution relatively uniform. Subsequently, the guide structure 5 guides the hot air.

[0041] like Figures 1 to 5 As shown, the transmission assembly includes a transmission frame 502 rotatably connected to one side of the swing arm 504, a guide groove 505 opened inside one side of the transmission frame 502, a stepper motor 503 installed inside one side of the outer frame 4, and a cam 506 installed at the end of the output shaft of the stepper motor 503 and slidably connected to the guide groove 505. Several sets of air guide plates 501 are arranged inside the fixed frame 1, and the several sets of air guide plates 501 are evenly distributed inside the fixed frame 1. A cylindrical rod is provided on the top of one side of the cam 506, and the cam 506 forms a sliding structure with the guide groove 505 through the rod.

[0042] In this embodiment of the invention, the stepper motor 503 starts and drives the cam 506 to rotate, causing the cam 506 to drive the transmission frame 502 to reciprocate through the guide groove 505. The transmission frame 502 then drives the air guide plate 501 to rotate through the swing arm 504 connected to it, adjusting the angle of the air guide plate 501. By precisely controlling the rotation angle of the stepper motor 503, the angle of each air guide plate 501 is adjusted, changing the flow direction and distribution of hot air, and precisely guiding the hot air to the area that needs to be dried, avoiding dead air zones, and improving the uniformity and efficiency of soybean protein drying.

[0043] like Figures 1 to 4 As shown, the cleaning structure 3 includes a transmission rod 302 rotatably connected to the top of the fixed frame 1, synchronous wheels 304 respectively installed on both sides of the transmission rod 302 and the bottom of both sides of the fixed frame 1, a synchronous belt 303 sleeved on the outside of the synchronous wheels 304 and connected to the cleaning brush 301, and a drive motor 305 installed on the top of the fixed frame 1 and connected to the output shaft end and the transmission rod 302. The cleaning brush 301 extends to the outside of the fixed frame 1 and is connected to the transmission rod 302. Soft brush bristles are arranged at equal intervals on one side of the cleaning brush 301.

[0044] In this embodiment of the utility model, the drive motor 305 drives the transmission rod 302 to rotate, so that the synchronous wheel 304 drives the cleaning brush 301 to move via the synchronous belt 303. As the cleaning brush 301 moves, the soft bristles on one side of the cleaning brush 301 sweep off the dust and foreign objects attached to the surface of the dust filter 2. The swept-off foreign objects will fall into the collection tank 7. When cleaning is required, the baffle 6 can be opened to discharge the foreign objects, thus completing the cleaning of the dust filter 2. By automatically cleaning the dust filter 2, the downtime caused by manual cleaning is avoided, which reduces maintenance costs to a certain extent. At the same time, the air permeability and filtration effect of the dust filter 2 are guaranteed, and the hot air flow guide plate is maintained for a long time and stable operation.

[0045] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
