Embodiment 1

[0025] Embodiment one, such as figure 1 As shown, the device for implementing the method of the present invention is to set a lower vent on the side wall of the lower part of the granulation high tower 1, and the top and bottom of the lower vent are provided with an upper floor that extends toward the inside of the tower. The baffle plate 2 and the lower floor slant the baffle plate 2 to prevent the compound fertilizer grain falling downwards from being thrown outside the air vent; prevent rainwater from entering the air vent by arranging a rain-proof awning 3 outside the lower part of the air vent. The rain-proof awning 3 extends around the lower vent, and the top has a rain-proof awning that is sealed and fixed with the outer wall of the granulation high tower above the lower vent, and the bottom has a granulation height below the lower vent. The ventilation fence seat fixed on the outer wall of the tower, the vertical rain shield is fixed between the rain shield and the ven...

Embodiment 2

[0027] Embodiment two, such as figure 2 As shown, the difference between the device for implementing the method of the present invention and the first embodiment is that the upper downward slope baffle plate 2 extends to the inner wall of the high granulation tower 1 on both sides. Preferably, it extends in a semicircle with the angle between the upper downslope baffle plate 2 and the inner wall of the tower as the center of the circle. The tower inner wall end of the extension part 21 further extends upward along the tower inner wall and is fixed together with the tower inner wall. And the lower sloping baffle 2 extends outwards to the outside of the lower vent.

Embodiment 3

[0028] Embodiment three, such as image 3 As shown, the difference between the device for implementing the method of the present invention and Embodiment 1 is that: the upper sloping baffle plate 2 adopts a sieve plate with holes smaller than the particle size of the compound fertilizer; and the sieve plate is equipped with a surrounding frame 60 And the frame that vertical support bar 61 forms. And the lower sloping baffle plate 2 also extends outwards to the outside of the lower vent.

Abstract

The invention relates to a method and a device for efficient ventilation of the lower part of a compound fertilizer granulating tower and aims to solve the problem of low ventilation efficiency in the prior art. The method comprises the following steps: blocking a compound fertilizer granule falling off downwards from being thrown to the outside of an air vent through arranging an upper layer of lower diagonal baffle capable of extending towards the inside of the tower or an upper layer of saddle-shaped baffle and a lower layer of lower diagonal baffle capable of flowing the compound fertilizer granule to the two sides at the top of or above and at the bottom of the air vent at the low part of the granulating tower; and preventing rainwater from entering the air vent through arranging a rainproof ventilation tent outside the air vent at the low part. The method is characterized in that the compound fertilizer granule falling off downwards is blocked from being thrown to the air vent through arranging the upper layer of lower diagonal baffle capable of extending towards the interior of the tower or the upper layer of saddle-shaped baffle and the lower layer of lower diagonal baffle capable of flowing the compound fertilizer granule to the two side at the top of or above and at the bottom of the air vent at the low part of the granulating tower; and the rainwater is prevented from entering the air vent through arranging the rainproof ventilation tent outside the air vent at the low part. The method and the device have the beneficial effects of uneasiness in fertilizer rush-out, small wind resistance, high ventilation efficiency, no water ingress, ensured product quality and yield, low cost, no fertilizer leakage and no pollution and loss.

Description

technical field [0001] The invention relates to a high-tower granulation ventilation technology, in particular to a high-efficiency ventilation method and device for the lower part of a compound fertilizer granulation high-tower. Background technique [0002] Ventilation at the lower part of the existing compound fertilizer granulation tower adopts louver-type natural air intake, fertilizer is easy to rush out, and it is also prone to insufficient ventilation at the lower part, which affects product output and quality. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned defects of the prior art, and provide a method for efficiently ventilating the lower part of a compound fertilizer granulation high tower with high ventilation efficiency and difficult fertilizer flushing out. The purpose of the present invention is also to provide a device for implementing the method. [0004] In order to achieve the above object, the ...
