Description

Technical Field

[0001] This utility model relates to the field of grain dryer technology, and in particular to a vertical circulating multi-layer rapid grain dryer. Background Technology

[0002] The vertical circulating grain rapid dryer is a high-efficiency and energy-saving modern drying equipment designed for large-scale grain processing. It typically adopts a vertical tower structure, where grains are repeatedly circulated under the action of hot air through internal lifting and scattering devices, ensuring that the grain particles are evenly heated and fully dried.

[0003] The traditional guide plates in current vertical circulating grain dryers can easily lead to uneven distribution of grains during circulation, resulting in uneven drying, local over-drying or under-drying. At the same time, wet grains are prone to clumping when initially fed, which can also cause blockage of the first feed hopper.

[0004] Therefore, those skilled in the art have provided a vertical circulating multi-layer rapid grain dryer to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a vertical circulating multi-layer rapid grain dryer. Grains are fed into a sieve box via a first feed hopper. A drive motor then rotates an eccentric wheel via a first and second cross shaft. Simultaneously, a connecting rod rotates another eccentric wheel, causing the sieve box to vibrate. This effectively reduces grain agglomeration and feed blockage, and improves feeding efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A vertical circulating multi-layer rapid grain dryer includes a first body, a drying mechanism is provided on the outer wall of one side of the first body, the drying mechanism includes a second body, a second feed hopper is provided on the upper surface of the second body, a rotating shaft is rotatably connected to the center of the inner top surface of the second body, a plurality of spiral blades are fixedly connected to the outer wall of the rotating shaft, a plurality of guide plates are fixedly connected to the inner wall of one side of the second body, a cross is fixedly connected to the lower end of the inner wall of the second body, and a second discharge port is fixedly connected to the lower surface of the second body.

[0008] The above technical solutions effectively increase the contact area between grains and hot air.

[0009] Furthermore, the upper surface of the first machine body is provided with a feeding mechanism, which includes a base fixedly connected to both sides of the front end of the upper surface of the first machine body. A spring is fixedly connected to the rear end of the upper surface of the base. A support plate is fixedly connected to the upper end of the spring. A screen box is fixedly connected to the outer wall of the rear end of the support plate. A first feed hopper is fixedly connected to the upper surface of the screen box. A first discharge port is fixedly connected to one side of the outer wall of the screen box. A support column is fixedly connected to the rear end of the upper surface of the base. A drive motor is fixedly connected to the upper surface of the support column. A second cross shaft is fixedly connected to the output end of the drive motor. The front end of the second cross shaft is hinged to the first cross shaft. Eccentric wheels are fixedly connected to both sides of the outer wall of the front end of the screen box. Connecting rods are rotatably connected to both sides of the inner wall of the front end of the screen box.

[0010] The above technical solutions effectively improve the grain feeding rate.

[0011] Furthermore, the second body is fixedly connected to one side of the outer wall of the first body, and a third body is fixedly connected to the outer wall of the second body away from the first body. An exhaust port is provided on the upper surface of the third body.

[0012] The above technical solutions effectively improve the emission of exhaust gases.

[0013] Furthermore, a hot air furnace is fixedly connected to the lower end of the first machine body;

[0014] The above technical solution effectively generates hot air.

[0015] Furthermore, the first cross shaft is hinged to the eccentric wheel, and the connecting rod passes through the screen box and is fixedly connected to the eccentric wheel;

[0016] The above technical solution enables the connecting rod to effectively drive the eccentric wheel at the other end to rotate.

[0017] Furthermore, a servo motor is fixedly connected to the upper surface of the second body, and the servo motor is fixedly connected to the rotating shaft;

[0018] The above technical solution effectively drives the shaft to rotate.

[0019] Furthermore, a ventilation duct is fixedly connected to the lower end of the outer wall on the adjacent side of the first and third bodies.

[0020] The above technical solution effectively enables low-temperature air to pass through ventilation ducts to the hot air furnace and form hot air.

[0021] This utility model has the following beneficial effects:

[0022] 1. The present invention proposes a vertical circulating multi-layer rapid grain dryer. The guide plate effectively prevents material accumulation when the grain falls, ensuring smooth flow. At the same time, the spiral blades increase the contact area between the grain and the hot air, effectively improving the moisture evaporation efficiency, thereby increasing the overall grain drying rate.

[0023] 2. The present invention proposes a vertical circulating multi-layer grain rapid dryer, in which grain is fed into a screen box through a first feeding hopper. Then, a drive motor drives an eccentric wheel to rotate through a first cross shaft and a second cross shaft. At the same time, the eccentric wheel on the other side is driven to rotate through a connecting rod, thereby causing the screen box to vibrate. This effectively reduces grain agglomeration and feeding blockage, and also improves feeding efficiency. Attached Figure Description

[0041] Reference Figure 5 , Figure 6 and Figure 7 ;

A screen box 4010 is fixedly connected to the outer wall of the rear end of the support plate 408. A first feed hopper 401 is fixedly connected to the upper surface of the screen box 4010. A first discharge port 402 is fixedly connected to one side of the outer wall of the screen box 4010. A support column 404 is fixedly connected to the rear end of the upper surface of the base 403. A drive motor 405 is fixedly connected to the upper surface of the support column 404. A second cross shaft 407 is fixedly connected to the output end of the drive motor 405. A first cross shaft 406 is hinged to the front end of the second cross shaft 407. An eccentric wheel 409 is fixedly connected to both sides of the outer wall of the front end of the screen box 4010. A connecting rod 4012 is rotatably connected to both sides of the inner wall of the front end of the screen box 4010.

[0043] Reference Figure 1 , Figure 2 and Figure 4 ;

[0044] The second body 201 is fixedly connected to one side of the outer wall of the first body 1. The outer wall of the second body 201 away from the first body 1 is fixedly connected to the third body 3. The upper surface of the third body 3 is provided with an exhaust port 6. The lower end of the interior of the first body 1 is fixedly connected to a hot air furnace 5. The first cross shaft 406 is hinged to the eccentric wheel 409.

[0045] Working principle: When the equipment is needed, cold air is first heated by the hot air furnace 5 and enters the second body 201.

The output of the drive motor 405 drives the first cross shaft 406 and the second cross shaft 407 to rotate, thereby driving the eccentric wheel 409 to rotate. The eccentric wheel 409 then drives the connecting rod 4012 to rotate, thereby causing the other eccentric wheel 409 to rotate. This causes the spring 4011 and the eccentric wheel 409 to vibrate the screen box 4010. Grains are then discharged into the second feed hopper 206 through the first discharge port 402. The grains are then evenly dispersed by the guide plate 202. The output of the servo motor 208 drives the rotating shaft 204 to rotate on the cross 205, thereby causing the spiral blades 203 to rotate at low speed, increasing the contact area between the grains and the hot air. The exhaust gas is then discharged through the exhaust port 6. The cold air is then circulated and heated through the ventilation pipe 7. Finally, the grains are discharged through the second discharge port 207.
