Description

Technical Field

[0001] This utility model relates to the field of grain processing technology, and more specifically, to a vertical tower-type grain drying device. Background Technology

[0002] In the grain processing industry, drying is a crucial step in ensuring grain storage quality and extending its shelf life, and the performance of drying equipment directly determines the grain drying efficiency and processing quality. Currently, most mainstream grain drying equipment on the market adopts a box-type or tower-type structure, using heating elements to raise the internal temperature of the equipment to achieve the evaporation of moisture from the grain.

[0003] However, existing drying equipment heats grains through a single heating zone, and the grains tend to clump together inside the equipment, preventing them from fully contacting the hot air. This not only prolongs drying time and reduces overall drying efficiency but also leads to localized over-drying or under-drying, severely impacting the processed quality of the grains. Furthermore, dust, particles, and other impurities easily adhere to the grain surface. Existing equipment typically relies on simple filters for filtration, which are often fixed and lack active vibration or auxiliary agitation mechanisms. This causes impurities to easily clog the filter pores, reducing screening efficiency and requiring frequent shutdowns for filter cleaning, increasing operating and time costs. Utility Model Content In order to overcome the shortcomings of the existing technology, this utility model provides a vertical tower-type drying device for grain processing.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a vertical tower-type grain drying device, comprising a drying chamber, a heating jacket fixedly connected to the outer wall of the drying chamber, a T-shaped rod slidably connected to the top of the drying chamber, a cam provided above the T-shaped rod, a U-shaped frame fixedly connected to one end of the T-shaped rod extending into the drying chamber, a mounting plate fixedly connected to the bottom of the U-shaped frame, a rotating shaft rotatably connected to the bottom of the mounting plate, a filter plate rotatably connected to the bottom end of the rotating shaft, and the filter plate slidably connected to the drying chamber, a plurality of equally spaced levers provided above the filter plate, and the levers fixedly connected to the rotating shaft, symmetrically distributed vertical rods fixedly connected to the inner wall of the top of the drying chamber, and the outer wall of the vertical rods slidably connected to the U-shaped frame, a limit block fixedly connected to the bottom of the vertical rod, a spring sleeved on the top of the limit block, and the other end of the spring fixedly connected to the U-shaped frame.

[0005] As a preferred embodiment of the present invention, a fixed base is fixedly connected to the top outer wall of the drying oven, and a first motor is fixedly connected to the top of the fixed base, and the output shaft of the first motor is fixedly connected to a cam.

[0006] As a preferred embodiment of this utility model, the mounting plate is a perforated plate structure, a second motor is fixedly connected to the top of the mounting plate, the output shaft of the second motor is fixedly connected to the rotating shaft, and a protective cover fixedly connected to the mounting plate is provided on the outer wall of the second motor.

[0007] As a preferred embodiment of this utility model, the outer wall of the rotating shaft is fixedly connected with a plurality of equally spaced dispersing rods, and the dispersing rods are located above the lever.

[0008] As a preferred embodiment of this utility model, the bottom of the filter plate is fixedly connected with symmetrically distributed guide rods, and the outer wall of the guide rods is slidably connected with a support block, which is fixedly connected to the drying oven.

[0009] As a preferred embodiment of this utility model, a feed hopper is fixedly connected to one side of the top of the drying box, and a discharge pipe is fixedly connected to the bottom of the drying box.

[0010] As a preferred embodiment of this utility model, a discharge pipe is fixedly connected to one side of the drying oven, and the discharge pipe is located below the heating jacket.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. In this utility model, when in use, the drying chamber is heated by the heating wire inside the heating jacket. After heating is completed, the grain is added into the drying chamber through the feed hopper for drying. The second motor is started, and the output shaft of the second motor rotates, which drives the rotating shaft to rotate, thereby causing the dispersing rod and the lever to rotate. The dispersing rod rotates to disperse the grain, and the lever moves the grain on the filter plate to improve the drying efficiency. 2. In this utility model, after drying is completed, the first motor is started. The output shaft of the first motor rotates, which drives the cam to rotate. When the cam contacts the T-shaped rod, the cam pushes the T-shaped rod, causing the T-shaped rod to move down and thus driving the U-shaped frame to move down. The movement of the U-shaped frame drives the mounting plate, the rotating shaft and the filter plate to move. When the cam is not in contact with the T-shaped rod, the spring resets and drives the filter plate to reset, realizing the vibration of the filter plate. The vibration of the filter plate and the movement of the lever improve the screening efficiency of the filter plate, making it easier to remove dust and impurities in the grain.

Under the action of the spring 4, the filter plate 17 vibrates to remove dust from the dried grain.

[0016] In actual use, the heating jacket 2 is equipped with multiple heating wires with a power of 1.5-3kW.

Heating is achieved through the heating wires, which are not shown in the figure. In actual use, an exhaust port (50-80mm in diameter) is added to the top of the drying chamber 1, and an axial flow fan (model BFAG-400, air volume of 800-1200m³ / h) is installed at the exhaust port. At the same time, an air inlet (with dust filter) is opened on the lower side wall of the drying chamber 1 to form a hot air circulation channel of "bottom air inlet - top air exhaust" to accelerate the discharge of hot and humid air.

[0017] The top outer wall of the drying oven 1 is fixedly connected to a fixed base 8, and the top of the fixed base 8 is fixedly connected to a first motor 7. The output shaft of the first motor 7 is fixedly connected to the cam 6. The model of the first motor 7 is 5IK120RGN-CF. The first motor 7 drives the cam 6 to rotate.

[0018] The mounting plate 12 has a perforated plate structure. A second motor 11 is fixedly connected to the top of the mounting plate 12. The output shaft of the second motor 11 is fixedly connected to the rotating shaft 14. The model of the second motor 11 is 42HS40-1704. The outer wall of the second motor 11 is provided with a protective cover 13 fixedly connected to the mounting plate 12.

[0019] The outer wall of the rotating shaft 14 is fixedly connected with multiple sets of equally spaced dispersing rods 15, and the dispersing rods 15 are located above the lever 16. The grains are dispersed by rotating the dispersing rods 15 to prevent the grains from clumping together and affecting the heating.

[0020] The bottom of the filter plate 17 is fixedly connected with symmetrically distributed guide rods 18. The outer wall of the guide rods 18 is slidably connected with a support block 19, and the support block 19 is fixedly connected to the drying oven 1. The guide rods 18 and the support block 19 guide the movement of the filter plate 17 and restrict the rotation of the filter plate 17.

[0021] The top side of the drying chamber 1 is fixedly connected to a feed hopper 5, and the bottom of the drying chamber 1 is fixedly connected to a discharge pipe 20. The feed hopper 5 is used to feed the material, and the discharge pipe 20 is used to discharge the filtered dust and impurities.

[0023] Working principle and usage process of this utility model: In this application, when in use, the heating jacket 2 is started to preheat the inside of the drying box 1 to the preset temperature. The grain to be dried is then fed into the drying box 1 at a uniform speed through the feed hopper 5. The drying process is carried out by continuous heating. The second motor 11 is started. The output shaft of the second motor 11 rotates, which drives the rotating shaft 14 to rotate, thereby causing the dispersing rod 15 and the lever 16 to rotate. The dispersing rod 15 rotates to disperse the grain, and the lever 16 moves the grain on the filter plate 17 to improve the drying efficiency. In this application, after drying is completed, the first motor 7 is started. The output shaft of the first motor 7 rotates, which drives the cam 6 to rotate. When the cam 6 contacts the T-shaped rod 9, the cam 6 pushes the T-shaped rod 9, causing the T-shaped rod 9 to move down, which in turn drives the U-shaped frame 10 to move down. The movement of the U-shaped frame 10 drives the mounting plate 12, the rotating shaft 14 and the filter plate 17 to move. When the cam 6 is not in contact with the T-shaped rod 9, the spring 4 resets, which drives the filter plate 17 to reset, thus realizing the vibration of the filter plate 17. The vibration of the filter plate 17 and the movement of the lever 16 improve the screening efficiency of the filter plate 17, which facilitates the removal of dust and impurities in the grain. In this application, the screened dust and impurities are discharged through the discharge pipe 20, and the processed grains are discharged through the discharge pipe 3 under the action of the lever 16.
