Description

Technical Field

[0001] The utility model relates to the technical field of compound fertilizer processing, and specifically relates to a ventilation device for high tower compound fertilizer. Background Technique

[0002] High tower compound fertilizer is a new type of high-efficiency fertilizer, and its production process adopts high tower melt granulation technology. This technology melts raw materials such as urea, phosphorus, and potassium and sprays them down from the top of the high tower, and granulates through natural cooling to produce granular compound fertilizer. Compared with traditional fertilizers, high tower compound fertilizer has many advantages. It is a new type of fertilizer that is efficient, environmentally friendly, and energy-saving, and has broad market prospects and application value; in the production of high tower compound fertilizer, harmful gas damage will occur. In order to maintain the stability of the production environment, a ventilation device is often required.

[0003] During the production process of high tower compound fertilizer, it needs to go through the links of high-temperature melting and cooling granulation. During cooling, the compound fertilizer particles will fall rapidly, which may cause uneven cooling of the compound fertilizer particles with faster falling speed. Traditional ventilation devices can only ventilate and breathe, but cannot effectively slow down the falling speed of compound fertilizer during cooling, affecting the product quality and production efficiency. For this reason, we propose a ventilation device for high tower compound fertilizer. Content of the Utility Model

[0023] Please refer to Figures 1-3 , a ventilation device for high tower compound fertilizer, including a bottom bin 1 for high tower compound fertilizer, a rotating motor 2 is fixedly connected to the bottom of the bottom bin 1 for high tower compound fertilizer, a control panel 3 is fixedly connected to the side of the bottom bin 1 for high tower compound fertilizer, the control panel 3 is electrically connected to the rotating motor 2, both sides of the bottom bin 1 for high tower compound fertilizer are of an open structure and fixedly connected with a compound fertilizer discharge hopper 4, a cooling high tower 5 is fixedly connected to the top of the bottom bin 1 for high tower compound fertilizer, a feeding hopper 7 is fixedly connected to the top of the cooling high tower 5, and further includes:

[0024] A ventilation device 15, located at the lower end of the side of the cooling high tower 5, for blowing air;

[0025] A buffer device 16, located in the inner cavity of the bottom bin 1 for high tower compound fertilizer, for blowing air upward to reduce the falling speed of the compound fertilizer.

[0026] Further, a fixing ring 6 is fixedly connected to the side of the cooling high tower 5 for fixing the ventilation device 15.

[0027] Further, the ventilation device 15 includes a fan 8 and a ventilation strip 10. A plurality of fans 8 arranged in an annular equidistant manner are fixedly sleeved on the cooling high tower 5. The lower end of the fan 8 is fixedly inserted into the outer side of the cooling high tower 5. A plurality of ventilation strips 10 corresponding to the fans 8 one by one are fixedly connected to the inner wall of the cooling high tower 5.

[0028] Further, the side of the ventilation strip 10 away from the inner wall of the cooling high tower 5 is inclined. The inner cavity of the ventilation strip 10 is hollow, and the lower end is communicated with the air outlet of the fan 8. A plurality of air holes 11 are opened on one side of the ventilation strip 10 for air outlet and accelerating the air flow rate.

[0029] Further, the buffer device 16 includes a rotating rod 12, a fan 13 and a convex base 14. A convex base 14 is fixedly connected to the bottom inner wall of the bottom bin 1 for high tower compound fertilizer. A rotating rod 12 is movably inserted on the upper surface of the convex base 14. A fan 13 is fixedly connected to the rotating rod 12. The lower end of the rotating rod 12 extends to the bottom of the bottom bin 1 for high tower compound fertilizer and is fixedly connected to the rotating motor 2.

[0030] Furthermore, the fan 13 is in the shape of a frustum of a cone protruding upward.

[0031] Working principle: When the device is required to ventilate the compound fertilizer, the fan 8 is turned on in advance. After the air flow generated by the fan 8 passes through the inner cavity of the ventilation strip 10, it is discharged along the air holes 11. Since multiple ventilation strips 10 are arranged in a ring, and the side surface of the ventilation strip 10 is inclined, the air flow generated by the fan 8 forms a rotating air flow in the inner cavity of the cooling tower 5 after passing through the ventilation strip 10 and the air holes 11. Then, the rotating motor 2 is turned on, and the rotating rod 12 is driven to rotate by the rotating motor 2. The rotation of the rotating rod 12 drives the fan 13 to rotate together. The rotation of the fan 13 generates an upward air flow, and the rotation direction of the fan 13 is the same as the direction of the rotating air flow generated by the fan 8. After preparation, the compound fertilizer particles after high-temperature melting are dropped into the feeding hopper 7. The compound fertilizer particles enter the cooling tower 5 from the feeding hopper 7 for falling and cooling. The rotating air flow will generate an upward lifting force on the compound fertilizer particles. This lifting force is opposite to the gravity and can slow down the falling speed of the particles. In addition, the rotating air flow will also make the particles form a certain movement trajectory in space. This trajectory can further disperse the falling of the particles and make them cool more evenly. The cooled compound fertilizer particles fall onto the convex base 14 and flow to the outside along the inclined surface of the convex base 14 under the action of gravity through the fan 13.
