Description

Corn mildew removal equipment and method

technical field

The invention relates to the technical field of agricultural machinery, and further relates to a complete set of equipment and a method for removing mildew from moldy corn and removing dust from dry corn.

Background technique

Corn is the main raw material of energy feed for livestock and poultry, and it accounts for a relatively high proportion in the diet, generally 50% to 70%. my country's corn planting area is about 300 million mu, distributed in about 24 provinces, cities, and autonomous regions. The annual output ranks second in the world, accounting for about 20% of the world's total output. However, China is a country severely affected by mycotoxins, especially in rainy years, 100% of the corn is attacked by mycotoxins, most of the corn is moldy and deteriorated, and even recessive deterioration occurs when it is not harvested, and livestock and poultry eat it The aflatoxin produced by moldy corn causes poisoning and brings great harm to the breeding industry. Therefore, it is an objective need to invent a kind of corn mildew removal equipment.

Contents of the invention

The purpose of the present invention is to provide a kind of equipment suitable for large-scale breeding of livestock and poultry feed, especially corn surface moldy substances, to remove impurities and corn epidermis where mycotoxin is located, so as to achieve the purpose of removing mold and impurities from corn.

In order to achieve the above object, the present invention adopts the following scheme:

A complete set of corn mold removal equipment, including a screw conveyor, a corn mold remover and a cyclone dust collector, the screw conveyor is located on one side of the corn mold remover, and sends the material to the feed port of the corn mold remover, The corn mildew remover includes a silo equipped with a screen, and a rotating shaft is arranged in the silo, and groups of steel wire wheels are arranged helically on the outer ring of the rotating shaft, and the rotating shaft The wire wheel is driven to rotate under the drive of the driving device, and the end of the silo is provided with a discharge channel and an air duct with a centrifugal fan installed at one end, and the other end of the air duct is connected with the cyclone dust collector through an exhaust duct; the said The driving device, screw conveyor and cyclone dust collector are centrally controlled by an electric control cabinet, which is easy to operate and has a high degree of automation.

Further, the screw conveyor includes a feeding hopper, a screw auger, and a motor. The moldy corn is put into the feeding hopper, and the motor drives the screw dragon to rotate, and the moldy corn is transported to the feed port of the corn mold removing machine; the feeding hopper With a hatch, the hatch can be closed after the corn is poured into bags, which not only prevents the corn from bursting out when the auger rotates, but also prevents the dust in the corn from spreading into the air.

Further, the rotating shaft at the feed end is also equipped with a paddle, which can prevent bridging and blockage when the amount of corn is large, and the paddle can break up the aggregated corn kernels and regenerate the fluidity of the corn kernels;

Further, an auger is installed on the rotating shaft in the silo, and a mounting bracket is evenly arranged along the helix on the helical blade of the auger, and the wire wheel is fixed on the mounting bracket by means of bolt fastening, so that the wire wheel Quick replacement after wear;

Furthermore, the number of steel wire wheels installed can be controlled according to the degree of mildew on the corn skin, so as to avoid excessive wear on the corn kernels and cause food loss when the number of steel wire wheels is too large;

Further, the silo also includes an impurity discharge port at the bottom and an air exhaust port connected to the air duct. A slide plate that pushes and pulls up and down is installed on the impurity discharge port, and the discharge port is closed downward when the equipment is working. The material port, so that the gas in the silo is discharged from the exhaust port into the cyclone dust collector. The cyclone dust collector is connected with the dust collection bag. When the work is finished, the discharge port can be opened to clean out the impurities in the silo;

Further, the centrifugal fan is fixed on the wall of the silo by bolts, the air channel crosses the discharge channel, and a layer of cross-arranged steel wire mesh is installed at the intersection. When blowing from bottom to top, the brushed corn skin is blown out through the air duct, and the heavier corn kernels slide through the steel wire mesh and flow out of the discharge port to separate the skin impurities from the polished corn;

Further, there is a certain gap between the wire wheel and the sieve, and the corn is pushed forward while being polished by the wire wheel in the sieve, and the brushed off corn skin, including moldy substances, is blown out by the strong wind of the centrifugal fan. Impurities, including stones, dust, crushed corn grains, etc. are filtered out through the screen, fall into the discharge bin, and are discharged from the impurity discharge port.

Further, an air channel is also provided on the top of the side wall at the end of the silo, and the air channel is connected with the dust bag. Road blows out.

Utilize above-mentioned device to carry out the method for mildew removal as follows:

1. Open the hatch of the feeding hopper, pour the moldy corn into the feeding hopper, and close the hatch;

2. Turn on the screw conveyor, and the screw dragon will push the material to the feed port of the corn mold remover;

3. Turn on the motor, and the motor drives the rotating shaft to rotate through the belt and pulley. The front section of the rotating shaft is equipped with a feeding auger. screen;

4. The steel wire wheel at the back section of the rotating shaft is inside the circular screen and has a certain gap with the screen wall. The rotating shaft drives the steel wire wheel to rotate at high speed and rubs against the moldy corn. The steel wire wheel will remove the mildew on the surface of the moldy corn. The outer skin is brushed off, and at the same time, the material is pushed towards the discharge port;

5. During the advancing process of the material through the screen, impurities smaller than the aperture of the screen, such as dust, stones, and broken corn grains, leak out of the screen, and are cleaned regularly from the impurity discharge port in the later stage; at the same time, the high-speed rotating wire wheel disturbs the silo The air inside forms a positive pressure to push the lighter dust into the cyclone dust collector through the exhaust pipe, and the dust particles are separated from the airflow by centrifugal force and fall into the dust bag under the action of gravity along the inner wall.

6. The complete corn kernels with mildewed husks on the surface enter the discharge channel together with the husks. At the same time, a centrifugal fan blows into the air channel. The air channel crosses at the end of the discharge channel, and the intersection is covered with a layer of fine steel wire. The pore size of the net and steel mesh is smaller than the size of the corn kernels, so that the corn kernels can be discharged from the discharge port through the intersection, while the lighter moldy skin, dust and other impurities are taken away by the high-speed air along the air duct to achieve mildew. Separation of the husk from the kernel.

All the circuit parts of this set of processing equipment are centralized in the electric control cabinet to facilitate the coordinated work between the equipment, which is safe and reliable. The final processed corn kernels are bright in color, full in grain, clean in working environment, free of dust pollution, and low in labor intensity.

The beneficial effects of the present invention are as follows:

The high-speed rotation of the wire wheel drives the movement of the surrounding air. Small particles of impurities such as dust and dust that pass through the screen enter the cyclone dust collector through the exhaust pipe, making the dust-laden air flow rotate, and the dust particles are separated from the air flow by centrifugal force. The dust particles are separated and collected on the wall of the device, and then the dust particles fall into the collection bag by the action of gravity. The dust pollution in the working environment can be effectively avoided, the working environment can be improved, and the problems of a large amount of dust pollution caused by existing corn mildew removal equipment, causing personal injury and unsafe production can be solved.
