Detailed ways

The technical solutions of the present invention are further described below, but the claimed scope is not limited to the description.

As shown in Figures 1 and 2, a fertilizer drying equipment includes a barrel 1, a motor 2, and a stirring paddle 3. The motor 2 is fixed on the upper part of the barrel 1, and the motor 2 is connected to the stirring paddle 3. The said motor 2 is connected to the stirring paddle 3. The stirring paddle 3 is vertically installed in the barrel 1 through a bearing. The lower part of the barrel 1 is provided with an air intake pipe 4, which is connected to the inner cavity of the barrel 1. The upper part of the barrel 1 is provided with an exhaust pipe 5 to exhaust the air. Two sides of the pipe are provided with ion wind rods 6 , the ion wind rods 6 are installed on both sides of the exhaust pipe 5 , and the air outlet of the ion wind rod 6 is communicated with the inside of the exhaust pipe 5 .

When the fertilizer is dried, it enters the barrel 1 from the feeding port on the upper part of the barrel 1. When the equipment is working, the air fed by the fan 8 is heated by the heater 9, and then sent into the barrel 1 through the air inlet pipe 4, and the hot air is heated. After being in contact with the fertilizer particles, they are heated to increase the temperature of the fertilizer and the barrel 1, so that the moisture in the fertilizer volatilizes quickly, becomes gaseous, and is discharged from the exhaust pipe 5. Driven by the stirring paddle 3, Fertilizers can collide with each other, which will produce fertilizer dust. These dusts will be charged after friction with the airflow or with the stirring paddle 3. When they are discharged from the exhaust pipe 5, they will adhere to the exhaust pipe 5, and the ion wind rod 6 will pass through. High-voltage ionized air can generate a large number of air masses with positive and negative charges, and under the action of compressed air, the fertilizer dust is blown oppositely. The charge on the fertilizer dust will be neutralized by the electric charge in the air mass, thereby reducing dust. Increase the adhesion speed, reduce the frequency of cleaning the exhaust pipe, and improve the normal working time of the equipment.

The air blowing direction of the air outlet of the ion wind bar 6 is inclined downward, and has an included angle of 50° to 70° with the horizontal plane, so that the air flow blown by the ion wind bar 6 can collide with the air flow discharged from the exhaust pipe 5, and improve the Charge neutralization efficiency.

The barrel 1 is provided with a spoiler 7, and the spoiler 7 is vertically installed on the inner wall of the barrel 1. Driven by the stirring paddle 3, the fertilizer particles will move together with the stirring paddle 3, and the stirring effect is poor. The spoiler 7 can turn the material flow so that it can turn up and down to improve the stirring effect.

There are two air inlet pipes 4, the air inlet pipe 4 is connected with the barrel body 1 along the tangential direction of the barrel body 1, the air outlet direction of the air inlet pipe 4 is the same as the rotation direction of the stirring paddle 3, and the hot air enters the barrel body 1 through the air inlet pipe 4. In the process, the fertilizer granules and the inside of the barrel 1 are heated to accelerate the volatilization rate of water.

Also includes a fan 8 and a heater 9, the fan 8 is connected in parallel with the two air intake pipes 4 through the heater 9, and the hot air is generated by the fan 8 and the heater 9, and the fertilizer particles and the interior of the barrel 1 are heated to accelerate the moisture. volatilization rate.

The lower part of the barrel body 1 is provided with a discharge port, the discharge port is provided with a discharge plate 10, the discharge plate 10 is hinged with the lower part of the barrel body 1, and one end of the discharge plate 10 is connected with the barrel body 1 through the oil cylinder 11, The opening and closing of the discharge plate 10 is controlled to reduce labor intensity and improve efficiency.
