Granulator capable of preventing central tubular beam from scaling

Abstract

The invention relates to a granulator capable of preventing central tubular beam from scaling, which comprises a kiln body, a central tubular beam and an ammonia distributor, wherein the central tubular beam is provided with a material bonding-preventing device consisting of a flexible baffle plate and a bracket; the flexible baffle plate is fixed above the central tubular beam by the bracket; and the flexible baffle plate is made in a size big enough to cover the upper part and the two sides of the central tubular beam. When accumulated in a certain weight, the materials falling onto the flexible baffle plate will fall off with the deformation of the baffle plate, the scaling-preventing effect is desirable, the machine-stop cleaning time is prolonged greatly, the normal and stable operation of production is ensured, and the production cost is reduced.

Description

technical field [0001] The invention relates to a granulator for producing phosphate compound fertilizer, in particular to a granulator capable of preventing the central pipe beam from scabbing. Background technique [0002] At present, the granulator required in the phosphate compound fertilizer plant, such as figure 1 As shown, a rigid tapered baffle plate 5 in the shape of a pagoda spire is provided above its central pipe beam 2 to prevent material caking. During the granulation process, the kiln body 4 rotates on the supporting roller 1 in the direction of the arrow in the figure, and the wet material reacted in the tubular reactor is sprayed into the granulator through the nozzle 3. During the spraying process, a small part of the wet material It is directly sprayed onto the central pipe beam 2 and the ammonia distributor 7, and the wet material 6 in the granulator is also continuously sprinkled on the central pipe beam 2 and the ammonia distributor 7 during operation,...

Problems solved by technology

During the granulation process, the kiln body 4 rotates on the supporting roller 1 in the direction of the arrow in the figure, and the wet material reacted in the tubular reactor is sprayed into the granulator through the nozzle 3. During the spraying process, a small part of the wet material It is directly sprayed onto the central pipe beam 2 and the ammonia distributor 7, and the wet material 6 in the granulator is also continuously sprinkled on the central pipe beam 2 and the ammonia distributor 7 during operation, and the wet material will be adsorbed in the center The surface of the tapered baffle plate 5 and the ammonia distributor 7 of the pipe beam accumulates into scars and quickly accumulates and grows up. Usually, the production can only last for about 2 hours and it needs to be stopped and cleaned once. Otherwise, the central pipe beam will be damaged and seriously damaged. It hinders the material making process of the granulator, and it takes at least 2 hours to clean each time, the production cannot run normally and stably, and the driving rate cannot be improved
