Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of compound fertilizer production, and particularly relates to a double-layer disc rotary arm type material collecting machine. BACKGROUND

[0002] At present, in the process of producing compound fertilizer by melt method high tower granulation, the compound fertilizer particles falling from the high tower naturally fall on the bottom collecting disc due to gravity, and are collected by the bottom collecting mechanism and discharged from the material passage of the collecting disc. The existing high tower bottom collecting machine adopts a disc spiral type collecting machine in the early stage, a circular discharge port is arranged at the center of the collecting disc, a collecting screw is arranged on each of the two sides along the diameter of the discharge port, the rotating directions of the two screws are opposite and the two screws simultaneously push the material to the discharge port. A power mechanism is arranged below the disc, a pinion is arranged on the power mechanism, the pinion drives a gear wheel to rotate, the gear wheel is connected with the collecting disc, so that the collecting disc is driven to rotate, the compound fertilizer particles on the collecting disc are rotated to the collecting screw, and the collecting screw collects the compound fertilizer particles to the discharge port for discharge. The existing equipment adopts a center discharging mode and side air cooling. Two layers of conical hoppers are arranged above the collecting disc, and cooling air is introduced from the middle of the two layers of conical hoppers. Since the compound fertilizer particles falling freely from the high tower have a high temperature when being sprayed by the granulator and are in a slurry state, the compound fertilizer particles need to be cooled to a certain temperature during the falling process, so as to become solid and have enough strength, so that the particles are not broken or deformed when falling on the collecting disc, and become smooth and qualified products. However, the natural temperature drop of the compound fertilizer particles during the falling process is small, so cooling air needs to be introduced for forced cooling. The material curtain formed by the falling compound fertilizer particles is in a bell shape, and the cooling air is introduced from the middle of the two layers of conical hoppers. Since the cooling air inlet position is high, the cooling air cannot enter the inside of the material curtain, and can only cool the compound fertilizer particles from the outside, so the contact area is small and the temperature drop is small, so that part of the compound fertilizer particles are broken or deformed due to insufficient strength when falling on the collecting surface because the temperature is not cooled to the required temperature, the yield is reduced, the waste product rate is as high as 20%, and the general rate is about 15%, so that the yield is low.

[0028] In view of the defects of the prior art, it is urgent to provide a new material collecting equipment, but at present, many manufacturers are still using the disc spiral material collecting machine, if it is abandoned, it will be higher to make a new material collecting machine, in order to reduce the waste rate, improve the yield, and try to reduce the reconstruction cost, in view of the defects of the existing single-layer disc material collecting equipment at the bottom of the high tower compound fertilizer, such as Figs. 1-3The application provides a double-layer disc rotary arm type material collecting machine, which comprises a prilling tower 7, a driving mechanism 8 and a material collecting plate 9. The bottom of the prilling tower 7 is provided with a first material collecting disc 1 which is a disc. A material collecting platform 3 corresponding to the edge of the first material collecting disc 1 is arranged at the bottom of the prilling tower 7. A taper edge 10 corresponding to the first material collecting disc 1 is arranged on the inner wall of the prilling tower 7. The taper edge 10 is an upper taper bucket of the original equipment. An annular second material collecting disc 16 is arranged on the inner side of the taper edge 10. Taking a compound fertilizer production line with an annual output of 300,000 tons of compound fertilizer and a prilling tower diameter of 19 meters as an example. The second material collecting disc 16 is a circular ring structure with an outer diameter of 19 meters and an inner diameter of 12 meters. The first material collecting disc 1 is still of the original structure. An air inlet 15 corresponding to the first material collecting disc 1 and the second material collecting disc 16 is arranged on the side wall of the prilling tower 7. Cooling air enters the compound fertilizer particle curtain from the channel between the upper and lower material collecting surfaces and contacts the compound fertilizer particles falling from the tower to cool the compound fertilizer particles. The ventilation area of the structure is 74 square meters, while the original ventilation area is only 25 square meters. The ventilation area is greatly increased, the cooling effect is significantly improved, the waste rate can be reduced to about 5%, the yield is improved, and thus the defects that the cooling air inlet position is high and the cooling air cannot enter the compound fertilizer particle curtain in the prior art are solved. The structure enables the cooling air to enter the compound fertilizer particle curtain, and promotes rapid cooling of the particles. The improvement of the technical scheme of the application only needs the upper taper bucket, and the lower taper bucket is no longer needed. In order to minimize the reconstruction cost, the second material collecting disc 16 is made of the material removed from the lower taper bucket.

[0029] The first material collecting disc 1 is rotationally connected in the prilling tower 7. The driving mechanism 8 is arranged at the bottom of the first material collecting disc 1 and drives the first material collecting disc 1 to rotate.
