Description

Technical Field

[0001] This utility model relates to the field of dryer technology, specifically to a circulating grain dryer continuous operation device. Background Technology

[0002] A circulating grain dryer is a device that, after being filled with grain, circulates it N times to continuously reduce the moisture content of the grain until it reaches the national standard before releasing it from the dryer. Regardless of the moisture content, the grain must undergo N circulations within the dryer; this is mainly determined by the inlet air temperature and the machine's own dehydration rate.

[0003] This feature of the circulating grain dryer is suitable for grains with high moisture content. The total time for feeding, multiple cycles, and unloading is generally 16 hours or even longer. However, for grains with low moisture content, the feeding + multiple cycles + unloading time is quite long. To save time and reduce production costs, a continuous operation device for the circulating grain dryer is needed, allowing users to apply it to grains with low moisture content, thus enabling the circulating grain dryer to serve two purposes. Utility Model Content

[0004] The purpose of this invention is to provide a circulating grain dryer continuous operation device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A continuous operation device for a circulating grain dryer includes: A self-circulating dryer and a main elevator are provided. The bottom of the self-circulating dryer is equipped with a discharge hopper. The discharge hopper is equipped with a discharge pipe, a connecting pipe and a lifting pipe. The lifting pipe is connected to a self-elevating machine. Several self-circulating dryers are arranged in sequence. A screw conveyor is provided, with the connecting pipes and lifting pipes of two adjacent self-circulating dryers correspondingly arranged, and the screw conveyor connects the corresponding connecting pipes and lifting pipes; The hot air assembly includes a hot air furnace and air supply pipes mounted on the hot air furnace and connected to the self-circulating dryer. The hot air furnace blows hot air into the self-circulating dryer through the air supply pipes. The main elevator feeds the material into the self-circulating dryer, where it is dried by the hot air and then flows through the connecting pipe into the screw conveyor. The screw conveyor then feeds the material into the lifting pipe of another self-circulating dryer, allowing the self-elevator to deliver the grain to the next self-circulating dryer. The discharge pipe is used to discharge the dried material.

[0006] Preferably, the top of the self-circulating dryer is equipped with an automatic grain feeding scraper.

[0007] Preferably, the screw conveyor includes a housing, a cover plate disposed on the housing, a feed inlet disposed on the cover plate, a feed inlet cover plate disposed at the feed inlet, a reducing flange disposed on the feed inlet cover plate and connected to the connecting pipe, an auger disposed inside the housing, a conveying motor connected to the housing via a motor bracket, and a discharge pipe disposed on the housing and connected to the lifting pipe.

[0008] Preferably, the conveying motor drives the auger to rotate, sending the material flowing in from the grain inlet to the discharge pipe and into the lifting pipe.

[0009] Preferably, the housing is provided with support feet, and the support feet are provided with adjustable feet.

[0010] Preferably, the hot air furnace includes a suspension furnace and an exhaust pipe disposed on the suspension furnace.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This utility model uses a screw conveyor, which reduces the conveying stroke compared to the N cycles in a self-circulating dryer. This reduces the number of collisions between hard objects and grains, shortens the drying time, and lowers production costs. With the discharge pipe, material can be discharged at any self-circulating dryer at any time. Attached Figure Description
