Description

Granule flows board cold ware feeding storehouse of board with cubic material is from clear away function

Technical Field

The patent relates to the application of a particle flow plate cooler, in particular to a particle flow plate cooler feeding bin with a block material self-cleaning function.

Background

With the development of industrial technology, the solid particle flow plate cooler is widely applied to the fertilizer industry, the ammonia-soda industry, the casting industry and the like. As the cooling roller in the compound fertilizer industry is completely replaced by the solid particle flow plate cooler, the defect that the solid particle flow plate cooler is easy to block is completely exposed. The blockage of the solid particle flow plate cooler mainly has the following defects:

1. blocky material gets into equipment, and the card is flowed cold ware heat transfer board upper portion at the granule, leads to equipment to block up even to park after the gathering.

2. The clearance difficulty needs personnel to get into the feeding storehouse from the top and clear up cubic material.

3. Potential safety hazards, some materials require nitrogen protection for use, such as calcium carbide; some materials are highly corrosive, such as calcium chloride; if personnel enter the interior of the equipment for cleaning, one more potential safety hazard operation point is still arranged even if the personnel are executed strictly according to the operation regulations.

4. Affecting the product quality, and part of the block materials enter the packaging process along with the materials. For example, the urea block material entering the packaging bag can affect the subsequent fertilizing process of farmers.

5. The mechanical operation of the equipment is influenced, for example, some block materials fall into a blanking device, particularly a hinge door blanking device, and the equipment is blocked and the operation of the equipment is influenced.

6. The process index is influenced, the material flow deflection is caused by the accumulation of the blocky materials in the middle area, the cooling discharge temperature is uneven, one part is higher, the other part is lower, and the operation of subsequent process equipment is influenced. For example, in the field of compound fertilizers, cooled materials need to be wrapped with an anti-caking agent or a coloring agent, and if the temperature is uneven, the materials can cause flowers, so that the materials have to be returned for treatment.
