Description

Technical Field

[0001] This utility model relates to the field of dryer technology, and in particular to an agricultural product processing dryer. Background Technology

[0002] Agricultural product dryers are key pieces of equipment in modern agriculture used for dehydrating and drying grains, fruits, vegetables, and other agricultural products. They typically consist of the dryer body, a door frame, and door panels for sealing the drying chamber. The sealing performance of the door panels directly affects the dryer's thermal efficiency, energy consumption, and the drying quality of the agricultural products. Currently, dryer door panels mostly use fixed rubber sealing strips for sealing. However, after long-term use, these sealing strips are prone to aging, wear, or deformation, leading to incomplete sealing and gaps.

[0003] The existing sealing structure has obvious defects: First, its sealing effect passively depends on the door panel clamping force, and it is very easy to fail when the hinge is loose or the door frame is slightly deformed; Second, the condition of the sealing strip cannot be monitored in real time, and operators can only indirectly judge whether the seal is intact by observation or phenomena such as a decrease in drying efficiency. It is difficult to quickly find and accurately locate the problem when a fault occurs, which brings inconvenience to the maintenance and stable operation of the equipment.

[0004] Therefore, we have proposed an agricultural product processing dryer. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an agricultural product processing dryer.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an agricultural product processing dryer, comprising a dryer body, a door frame fixedly connected to the dryer body, and door panels hinged to the door frame. Both door panels are provided with an inflation groove on one side of the door frame, and both door panels are detachably and fixedly connected with a U-shaped airbag on one side of the inflation groove.

[0007] An inflation assembly is installed on the top of the dryer body. Both output ends of the inflation assembly are fixedly connected to manual valve assemblies. Both manual valve assemblies are fixedly connected to hoses, which are fixedly connected to adjacent door panels and connected to adjacent inflation slots.

[0008] Furthermore, an electrical control box is fixedly connected to one side of the outer surface of the dryer body, and an alarm is fixedly connected to the top of the electrical control box. The setting of the electrical control box is conducive to controlling the overall operation.

[0009] Furthermore, both of the aforementioned U-shaped airbags include an outer frame and an inner frame, and both the outer frame and the inner frame are detachably and fixedly connected to the door panel. An elastic rubber membrane is fixedly connected between the inner frame and the outer frame. A U-shaped sealing gasket is fixedly connected to one side of the outer surface of both the outer frame and the inner frame, and the inflation groove is located between the two U-shaped sealing gaskets. The U-shaped sealing gasket is sealed and abuts against the door panel. The detachable fixed connection facilitates the replacement of the U-shaped airbags.

[0010] Furthermore, the inflation assembly includes an inflation pump, which is fixedly connected to the top of the dryer body. The output end of the inflation pump is fixedly connected to a solenoid valve, and the other interface of the solenoid valve is fixedly connected to a diverter pipe. The inflation pump provides a stable air source, and the solenoid valve controls the opening and closing of the air path.

[0011] Furthermore, a pressure sensor is fixedly connected to one side of the outer surface of the diversion pipe. By installing the pressure sensor on the diversion pipe, the pressure value of the entire inflation pipeline system can be monitored and fed back in real time.

[0012] Furthermore, both manual valve assemblies include manual ball valves, with one port of the manual ball valve being fixedly connected to the diverter pipe, and the other port of the manual ball valve being fixedly connected to a straight pipe. The straight pipe is fixedly connected to the dryer body and is fixedly connected to a hose. The hose allows the door panel to move without affecting the installation of the straight pipe.

[0013] The beneficial effects of this utility model are:

[0014] In use, this invention actively inflates the U-shaped airbag inside the door panel through the inflation component, forming a tight active seal and effectively improving the reliability of the seal. At the same time, the air pressure sensor in the inflation circuit monitors the sealing status in real time. Once a leak causes abnormal air pressure, an alarm is triggered. The specific faulty door panel can be quickly isolated and located by operating the manual valve component. This achieves real-time monitoring of the sealing effectiveness and rapid diagnosis of the fault point, overcoming the shortcomings of traditional fixed sealing strips that are passively sealed and cannot be monitored.

[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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-4 As shown, an agricultural product processing dryer is disclosed, comprising a dryer body 1, a door frame 5 fixedly connected to the dryer body 1, and door panels 4 hinged to the door frame 5. Each door panel 4 has an inflation groove 13 on one side of the door frame 5. Each door panel 4 has a U-shaped airbag detachably fixedly connected to one side of the inflation groove 13. Each U-shaped airbag includes an outer frame 15 and an inner frame 17, and both the outer frame 15 and the inner frame 17 are detachably fixedly connected to the door panel 4. The inner frame 17 and the outer frame 15 are jointly fixedly connected. An elastic rubber membrane 16 is provided. A U-shaped sealing gasket 14 is fixedly connected to one side of the outer surface of the outer frame 15 and the inner frame 17. The air groove 13 is located between the two U-shaped sealing gaskets 14, and the U-shaped sealing gaskets 14 are sealed and abut against the door panel 4. The outer frame 15 is fixed to the door panel 4 by a set of screws for easy disassembly and assembly. The inner frame 17 is also fixed to the door panel 4 by a set of screws for easy material handling. The two U-shaped sealing gaskets 14 are located between the two sets of screws, thereby ensuring the sealing performance of the inner frame 17 and the outer frame 15 after installation.

[0024] An inflation assembly is installed on the top of the dryer body 1. The inflation assembly includes an inflation pump 2, which is fixedly connected to the top of the dryer body 1. A solenoid valve 9 is fixedly connected to the output end of the inflation pump 2. A diverter pipe 8 is fixedly connected to the other port of the solenoid valve 9. A pressure sensor 10 is fixedly connected to one side of the outer surface of the diverter pipe 8. The solenoid valve 9 and the pressure sensor 10 are standard parts that can be purchased on the market. The solenoid valve 9 is used to control the opening and closing of the diverter pipe 8, and the pressure sensor 10 is used to detect the gas pressure.

[0025] Both output ends of the inflation assembly are fixedly connected to manual valve assemblies. Both manual valve assemblies are fixedly connected to hoses 6, and hoses 6 are fixedly connected to the adjacent door panel 4 and connected to the adjacent inflation slot 13. Both manual valve assemblies include manual ball valves 7, and one interface of manual ball valve 7 is fixedly connected to the diversion pipe 8. The other interface of manual ball valve 7 is fixedly connected to a straight pipe 11, and the straight pipe 11 is fixedly connected to the dryer body 1 and fixedly connected to hoses 6. Manual ball valve 7 is a standard part that can be purchased on the market and is used to control the opening and closing of straight pipe 11.

[0026] An electrical control box 3 is fixedly connected to one side of the outer surface of the dryer body 1. An alarm 12 is fixedly connected to the top of the electrical control box 3. The electrical control box 3 is electrically connected to the alarm 12, the solenoid valve 9, the air pressure sensor 10, and the air pump 2 to control the overall operation.

[0027] Working principle: When the two door panels 4 are closed, the air pump 2 starts to work and generates compressed air. The compressed air enters the diversion pipe 8 through the solenoid valve 9, and then is delivered to the air inlet 13 of the two door panels 4 through the two manual ball valves 7, the straight pipe 11, and the hose 6.

[0028] After the gas enters the inflation tank 13, it causes the elastic rubber diaphragm 16 to expand. After expansion, the elastic rubber diaphragm 16 is squeezed outward to form a tight seal with the door frame 5. After inflation is completed, the solenoid valve 9 closes.

[0029] During and after inflation, the air pressure sensor 10 monitors the air pressure in the diversion pipe 8 in real time. If both door panels 4 are well sealed, the U-shaped airbag will maintain a stable air pressure, and the air pressure detected by the air pressure sensor 10 will remain within a set range (usually preset by the control box 3).

[0030] If any of the door panels 4 leaks (e.g., the airbag ruptures or the gasket 14 is damaged), the gas in the inflation groove 13 will escape, causing a drop in the air pressure in the diversion pipe 8. When the air pressure sensor 10 detects an abnormal air pressure (e.g., below the threshold), it will immediately send a signal to the electrical control box 3, triggering the alarm 12 to issue an audible and visual alarm, alerting the operator that there is a sealing fault.

[0031] To pinpoint which door panel 4 has a damaged seal, the operator can close one of the manual ball valves 7 (e.g., close the manual ball valve 7 of the left door), stop inflating that door panel 4, and observe for a period of time. If the air pressure remains stable, it indicates that the currently inflated door panel 4 (right door) is properly sealed, while the previously closed door panel 4 (left door) has a leak. If the air pressure continues to drop, it indicates that the currently inflated door panel 4 (right door) has a damaged seal.

[0032] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
