Description

Technical Field

[0001] This utility model is a dryer based on gravity unloading. Background Technology

[0002] In the grain drying industry, dryers are indispensable equipment in the grain processing stage. Their main function is to dry the harvested, moist grain for long-term storage and to maintain its quality. Existing dryers mostly use a combination of mechanical conveying and hot air drying, feeding the grain into the drying unit for multiple cycles of drying until the moisture content reaches the required level before discharge. However, in traditional structures, the unloading and circulation paths of the dryer often rely on fixed pipelines or complex material distribution mechanisms for switching. If it is necessary to return undried grain to the drying unit, manual adjustment of baffles or alteration of the conveyor route is usually required. This is not only cumbersome but also prone to causing grain blockage and spillage during switching, increasing labor intensity and equipment maintenance difficulty.

[0003] Furthermore, the unloading systems of some existing dryers are complex, involving multiple electric valves or independent control mechanisms, which increases manufacturing and maintenance costs. For applications requiring frequent switching between cyclic drying and direct grain discharge, existing technologies have limitations in achieving rapid and reliable switching of grain flow direction, easily leading to increased burden on the drying mechanism, increased energy consumption, and impacting overall drying efficiency. Therefore, there is an urgent need for a dryer unloading system that is simple in structure, easy to switch between, and can flexibly control the flow direction according to the grain condition to improve the automation and operational efficiency of the drying process. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a dryer based on gravity unloading.

[0005] A gravity-discharge based dryer includes a drying mechanism, an elevator, and a three-way pipe. The elevator is used to transport grain into the drying mechanism and is located on the side of the drying mechanism. The three-way pipe includes a first pipe, a second pipe, and a third pipe that are connected to each other. The outlet of the drying mechanism is connected to the inlet of the first pipe. The outlet of the first pipe is also connected to the inlets of the second and third pipes. The outlet of the second pipe is a grain discharge port, and the outlet of the third pipe is connected to the feed inlet of the elevator.

[0006] A flap is installed at the junction of the first, second, and third pipes. The flap is rotatably connected inside the three-way pipe and is used to control the flow direction of grain inside the three-way pipe.

[0007] Preferably, the flap is a plate-shaped structure, with one end fixedly connected to the rotating shaft, which is rotatably connected inside the tee pipe.

[0008] Preferably, the drying mechanism includes, from top to bottom, a guardrail, a tempering section, a drying section, a circulation seat, and a support base. The guardrail is used to prevent grain from splashing, the tempering section is used to control the speed at which the grain falls, the drying section is used to dry the wet grain, the circulation seat is used to install the T-pipe, and the support base is used to support the overall structure.

[0009] Preferably, the side of the drying section is connected to the fan.

[0010] Preferably, the outlet of the elevator is connected to the inlet of the flow tube, and the outlet of the flow tube leads to the interior of the drying mechanism.

[0011] Beneficial effects: Compared with the prior art, this utility model controls the direction of grain passing through the three-way pipe by using a flap in the three-way pipe. When wet grain enters the machine and needs to be circulated for drying, the first and second pipes of the three-way pipe are connected. When drying is finished and the grain needs to be discharged, the first and third pipes are connected. The overall structure is simple and easy to operate. It can also realize the classification operation of grain state, reduce workload, reduce the burden on the drying mechanism, and improve efficiency. Attached Figure Description
