Description

Technical Field

[0001] This utility model relates to the field of grain storage, and in particular to a drying structure for a grain storage ventilation device. Background Technology

[0002] Grain warehouse ventilation and drying refers to the key technical measures taken during grain storage to achieve air exchange between the inside and outside of the grain warehouse or to treat the air inside the grain warehouse through specific equipment and technical means, thereby regulating the temperature and humidity inside the grain warehouse, reducing the moisture content of the grain, and thus ensuring the quality of the grain and preventing mold and insect infestation.

[0003] Currently, most existing grain warehouse ventilation equipment uses direct ventilation, which directly introduces humid outside air into the grain warehouse. This not only fails to dry the grain but also easily leads to increased humidity inside the grain warehouse, exacerbating the risk of grain mold. Furthermore, even if some equipment is equipped with drying components, the drying medium often cannot be fully agitated, resulting in insufficient contact between air and the drying medium and low drying efficiency, making it difficult to meet the drying needs of large-scale grain warehouses. To solve the above problems, we propose a drying structure for grain warehouse ventilation equipment. Utility Model Content

[0004] The main purpose of this utility model is to provide a drying structure for a grain storage ventilation device, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A drying structure for a grain storage ventilation device includes a first support frame, a control box fixedly installed on one side of the first support frame, a drying chamber fixedly connected to the upper end of the first support frame, a silica gel desiccant granule container fixedly connected to the inner cavity of the drying chamber, a stirring assembly provided in the inner cavity of the silica gel desiccant granule container, an exhaust pipe fixedly connected to one end of the drying chamber, a grain storage shell fixedly connected to the other end of the exhaust pipe, a ventilated grain storage container fixedly connected to the inner cavity of the grain storage shell, and a blowing drying assembly provided on the outer side of the ventilated grain storage container.

[0007] Preferably, an air intake pump is fixedly connected to the inner side of the first support frame, an air intake pipe is fixedly connected to the air inlet end of the air intake pump, an air outlet pipe is fixedly connected to the air outlet end of the air intake pump, and the other end of the air outlet pipe is connected to the inner cavity of the drying oven.

[0008] Preferably, the stirring assembly includes a rotating rod, which is rotatably connected to the drying box and the silica gel desiccant granule container. Multiple stirring shafts are fixedly connected to the outer side of the rotating rod, and the multiple stirring shafts are all located in the inner cavity of the silica gel desiccant granule container.

[0009] Preferably, a drive motor is fixedly connected to the outside of the drying oven, a drive wheel is fixedly connected to the output end of the drive motor, a belt is sleeved on the outside of the drive wheel, a driven wheel is sleeved on the inner side of the other end of the belt, the driven wheel is rotatably connected to the drying oven, and the driven wheel is fixedly connected to the rotating rod.

[0010] Preferably, the blowing drying assembly includes an annular vent pipe, which is located between the outer shell of the grain silo and the ventilated grain silo holding container, and is connected to the exhaust pipe. Multiple jet nozzles are installed on the outer side of the annular vent pipe, and the multiple jet nozzles are located on the side close to the ventilated grain silo holding container.

[0011] Preferably, the outer side of the annular vent pipe is also fixedly connected to multiple fixing brackets, and the other end of the multiple fixing brackets is fixedly connected to the inner wall of the grain silo shell.

[0012] Preferably, a rainproof and ventilated cover is fixedly connected to the upper end of the outer shell of the grain silo, and the rainproof and ventilated cover is located directly above the grain storage container in the ventilated grain silo.

[0013] Preferably, a grain collection and discharge cone is fixedly connected to the lower end of the grain silo shell, and a second support frame is fixedly connected to the lower end of the grain silo shell on the outer side of the grain collection and discharge cone.

[0014] Preferably, the upper end of the first support frame is fixedly connected to a mounting frame, the mounting frame is located on the air inlet side of the drying box, and the air outlet pipe is fixedly connected to the mounting frame.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The drying structure of this grain storage ventilation equipment draws in outside air through an air pump and first delivers it to the drying chamber. Silica gel desiccant granules in a container then dry the air. Simultaneously, a drive motor rotates the drive wheel, which, through belt transmission, drives the driven wheel to rotate the rotating rod and stirring shaft, thoroughly agitating the silica gel desiccant granules. This ensures complete and thorough contact between the air and the silica gel desiccant granules, greatly improving air drying efficiency and ensuring that the air entering the grain storage remains dry at all times. This prevents the adverse effects of humid air on grain storage from the source and reduces the probability of grain mold.

[0017] 2. The drying structure of this grain silo ventilation equipment allows air dried in the drying chamber to enter the annular ventilation pipe between the outer shell of the grain silo and the ventilated grain storage container through the exhaust pipe. Then, through multiple jet nozzles facing the ventilated grain storage container, the dried air is evenly sprayed onto the grain inside the ventilated grain storage container, achieving all-round air blowing and drying of the grain. At the same time, the rainproof ventilation cover at the top of the outer shell of the grain silo can promptly discharge the humid air generated during the grain drying process, forming a good air circulation. This not only ensures sufficient contact between the dried air and the grain, improving drying efficiency, but also meets the grain storage and drying needs of large-scale grain silos.

A silica gel desiccant granule container 14 is fixedly connected to the inner cavity of the drying chamber 7. A stirring assembly is provided in the inner cavity of the silica gel desiccant granule container 14. An exhaust pipe 16 is fixedly connected to one end of the drying chamber 7. A grain storage shell 17 is fixedly connected to the other end of the exhaust pipe 16. A ventilated grain storage container 19 is fixedly connected to the inner cavity of the grain storage shell 17. A blowing drying assembly is provided on the outer side of the ventilated grain storage container 19.

[0025] In this embodiment, an air intake pump 3 is fixedly connected to the inner side of the first support frame 1, an air intake pipe 4 is fixedly connected to the air inlet end of the air intake pump 3, an air outlet pipe 5 is fixedly connected to the air outlet end of the air intake pump 3, and the other end of the air outlet pipe 5 is connected to the inner cavity of the drying oven 7.

[0026] Specifically, during operation, the suction pump 3 installed inside the first support frame 1 is started first. At this time, outside air is drawn in through the air inlet pipe 4. The drawn-in air enters the air outlet pipe 5 through the air outlet end of the suction pump 3, and then the air is delivered to the drying chamber 7 at the upper end of the first support frame 1.

[0027] In this embodiment, the stirring assembly includes a rotating rod 12, which is rotatably connected to the drying chamber 7 and the silica gel desiccant granule container 14. Multiple stirring shafts 13 are fixedly connected to the outer side of the rotating rod 12, and the multiple stirring shafts 13 are all located in the inner cavity of the silica gel desiccant granule container 14. A drive motor 8 is fixedly connected to the outer side of the drying chamber 7, and a drive wheel 9 is fixedly connected to the output end of the drive motor 8. A belt 10 is sleeved on the outer side of the drive wheel 9, and a driven wheel 11 is sleeved on the inner side of the other end of the belt 10. The driven wheel 11 is rotatably connected to the drying chamber 7, and the driven wheel 11 is fixedly connected to the rotating rod 12.

[0028] Specifically, the drive motor 8 on the outside of the drying chamber 7 drives the drive wheel 9 to rotate. The drive wheel 9 drives the driven wheel 11 to rotate via the belt 10. The rotating rod 12, which is fixedly connected to the driven wheel 11, rotates in the drying chamber 7 and the silica gel desiccant granule container 14. Multiple stirring shafts 13 on the outside of the rotating rod 12 stir the silica gel desiccant granules in the silica gel desiccant granule container 14, so that the air entering the drying chamber 7 comes into full contact with the fully agitated silica gel desiccant granules, thereby achieving air drying.

Therefore, this paper will not elaborate further. Furthermore, this solution aims to protect the physical structure, not the circuitry or software control. The mention of the processing circuit in this paper is merely a supplementary explanation of the feasibility and authenticity of this utility model. This utility model does not require protection of the algorithm and circuitry technology. It is worth emphasizing that although this solution does not elaborate on the electronic control program, those skilled in the art can be familiar with and apply it based on their professional knowledge.

[0030] In this embodiment, the blowing drying assembly includes an annular vent pipe 20, which is located between the outer shell of the grain silo 17 and the ventilated grain silo holding tank 19. The annular vent pipe 20 is connected to the exhaust pipe 16. Multiple jet nozzles 22 are installed on the outer side of the annular vent pipe 20, and the multiple jet nozzles 22 are all located on the side close to the ventilated grain silo holding tank 19. Multiple fixing brackets 21 are also fixedly connected to the outer side of the annular vent pipe 20. The other end of the multiple fixing brackets 21 is fixedly connected to the inner wall of the outer shell of the grain silo 17. A rainproof vent cover 18 is fixedly connected to the upper end of the outer shell of the grain silo 17, and the rainproof vent cover 18 is located directly above the ventilated grain silo holding tank 19.

[0031] Specifically, the exhaust pipe 16 is connected to the annular ventilation pipe 20 located between the outer shell 17 of the grain silo and the ventilated grain storage tank 19. The annular ventilation pipe 20 is kept stable by the fixing action of multiple fixing frames 21. Dry air can enter the annular ventilation pipe 20 and be evenly sprayed onto the grain stored in the ventilated grain storage tank 19 through multiple jet nozzles 22 on the side near the ventilated grain storage tank 19 to dry the grain. The humid air generated in the process is discharged through the rainproof ventilation cover 18 at the upper end of the outer shell 17 of the grain silo. The design of the rainproof ventilation cover 18 can prevent rainwater from entering while ensuring smooth ventilation.

[0032] In this embodiment, a grain collection and discharge cone 23 is fixedly connected to the lower end of the grain silo shell 17, and a second support frame 24 is fixedly connected to the lower end of the grain silo shell 17 on the outside of the grain collection and discharge cone 23.

[0033] Specifically, the dried grain in the ventilated grain bin 19 can be easily discharged through the grain collection and discharge cone 23 at the lower end of the grain bin shell 17. The entire grain bin shell 17 remains stable under the support of the second support frame 24, and the operation of the entire equipment can be controlled by the control box 2 on one side of the first support frame 1.

[0034] In this embodiment, the upper end of the first support frame 1 is fixedly connected to the mounting frame 6, the mounting frame 6 is located on the air inlet side of the drying box 7, and the air outlet pipe 5 is fixedly connected to the mounting frame 6.

[0035] Specifically, the design of the mounting bracket 6 can improve the stability of the air outlet duct 5.

[0036] It should be noted that this utility model is a drying structure for a grain storage ventilation device. During operation, the suction pump 3 installed inside the first support frame 1 is first started. At this time, outside air is drawn in through the air inlet pipe 4, and the drawn-in air enters the air outlet pipe 5 through the air outlet end of the suction pump 3. Then, the air is delivered to the drying chamber 7 at the upper end of the first support frame 1. Simultaneously, the drive motor 8 on the outside of the drying chamber 7 operates, and its output end drives the drive wheel 9 to rotate. The drive wheel 9 drives the driven wheel 11 to rotate through the belt 10. The rotating rod 12, fixedly connected to the driven wheel 11, rotates within the drying chamber 7 and the silica gel desiccant granule container 14. Multiple stirring shafts 13 on the outside of the rotating rod 12 stir the silica gel desiccant granules in the silica gel desiccant granule container 14, ensuring that the air entering the drying chamber 7 comes into full contact with the fully agitated silica gel desiccant granules, thus achieving air drying. The dried air is then delivered to the outside of the grain storage through the exhaust pipe 16 at one end of the drying chamber 7. Inside the shell 17, the exhaust pipe 16 is connected to the annular ventilation pipe 20 located between the outer shell 17 and the ventilated grain storage tank 19. The annular ventilation pipe 20 is kept stable by the fixing action of multiple fixed frames 21. After the dry air enters the annular ventilation pipe 20, it is evenly sprayed onto the grain stored in the ventilated grain storage tank 19 through multiple jet nozzles 22 on the side near the ventilated grain storage tank 19, drying the grain. The humid air generated during the process is discharged through the rainproof ventilation cover 18 at the upper end of the outer shell 17. The design of the rainproof ventilation cover 18 can prevent rainwater from entering while ensuring smooth ventilation. The dried grain in the ventilated grain storage tank 19 can be discharged through the grain collection and discharge cone 23 at the lower end of the outer shell 17. The entire outer shell 17 is kept stable under the support of the second support frame 24, and the operation of the entire equipment can be controlled by the control box 2 on the side of the first support frame 1, which is quite practical.
