Description

An environmentally friendly grain removal and drying integrated machine

technical field

The invention belongs to the field of drying equipment, in particular to an environment-friendly grain impurity removing and drying integrated machine.

Background technique

my country is a big country of grain. After the grain is harvested, the removal of excess water from grain is the first step in grain storage or other processing. The traditional method of removing excess water from grain often relies on the weather and natural factors such as the sun to dry it. However, If it encounters continuous rainy weather, it will easily lead to grain mildew, germination, etc., resulting in huge waste of grain. Moreover, traditional methods of drying grains are time-consuming, labor-intensive and inefficient.

In order to improve the drying rate of grain and overcome the influence of weather, people have invented drying technology. According to different types of grain, various dryers have emerged on the market.

For example, the Chinese Patent Publication No. CN105265572B discloses a grain dryer, the grain dryer includes a dryer body, a grain inlet pipe and a grain outlet pipe, and the upper part of the dryer body is a soothing chamber , A guide device is arranged in the middle, and a guide chamber is located in the lower part. The guide device includes a plurality of helical structures, the interior of the helical structure is hollow, and the upper end of the helical structure communicates with the slowing chamber. The lower end of the helical structure is connected to the guide chamber, and a hot air channel is formed between the adjacent helical structures; the grain dryer also includes a hot air stove communicated with the hot air channel.

In the above scheme, a plurality of helical structures are arranged in the diversion device, and the hot air is introduced into the helical structure, so that the grain rolls from top to bottom in the helical structure body and the hot air is countercurrently dried, which simplifies the device and prolongs the food production. The residence time in the diversion device ensures the drying effect to a certain extent.

However, in the process of harvesting or transshipment, the grains are easily mixed with debris such as dust and stones.

Although the above solution ensures the drying effect to a certain extent, there is still a problem that the drying device has a single function and does not have the function of removing impurities.

The first motor drives the rotating rod to rotate the spiral sieve plate. On the one hand, it is convenient for the grain to roll downward to realize the downward transportation of the grain. On the other hand, the grain rolling can uniformly dry each surface of the grain. The rotation of the plate can stir the hot air in the drying box, make the hot air fully contact with the grain, and speed up the drying rate.

2. Set up a trash removal box, the grain falls from the top of the trash removal box, the cylinder body inhales to generate negative pressure, and the dust and empty shells in the grain are sucked into the cylinder body by the process of automatic falling of the grain.

During the falling of the grain, the dust is sucked into the cylinder 50. At the same time, the airflow causes the grain to be suspended above the conveyor belt 60 and the stone falls on the conveyor belt 60. The piston rod 52 The movement to the right drives the conveyor belt 60 and the hose 36 to move to the right, the grain falls into the lower hopper 21 under its own gravity, and the stone is transported to the far right end by the conveyor belt 60 and then falls into the chute 22 and is automatically discharged. When the piston 52 moves to the far left end When the second automatic valve 23 is opened, the grain automatically falls into the drying box 30. During the leftward movement of the piston 51, both the first automatic valve 12 and the second automatic valve 23 are closed, the cylinder 50 is exhausted, and the dust is filtered in the cylinder 50 and discharged side by side into the dust collection chamber 57 and finally settles in the cloth bag 59, Clean gas is discharged into the air. The grain enters the spiral sieve plate 42 in the drying box 30. With the rotation of the spiral sieve plate 42, the grain rolls down and is dried at the same time, and finally the grain is discharged into the discharge hopper 31. If the grain is qualified for drying, it can be opened. The third automatic valve 33 discharges the grain. If the grain is unqualified for drying, the third automatic valve 33 can be closed to allow the grain to enter the bucket elevator 34 and be dried again until it is qualified.

Repeat the above steps continuously to realize automatic intermittent impurity removal and automatic automatic continuous drying of grains.
