Anti-clogging and screening machine for compound fertilizer production

Abstract

The invention discloses an anti-blocking and sorting machine for compound fertilizer production, and mainly relates to the field of fertilizer production. It includes a machine base, a screening mechanism, and a blockage removal mechanism; the screening mechanism, the feeding mechanism, and the blockage removal mechanism are all installed on the machine base; the screening mechanism includes a drum, and the drum is a frustum-shaped cylinder with a linearly increasing inner diameter, and From its narrow end to its wide end, the drum includes the first sieve cylinder, the second sieve cylinder and the buffer cylinder which are connected successively at the first place, and a dust-proof cylinder is set on the circumference of the drum, and the bottom of the dust-proof cylinder is connected with negative pressure. Air source; the blockage removal mechanism includes a flexible block arranged on one side of the peripheral surface of the second screen drum, and the side of the flexible block adjacent to the drum is provided with an action surface, and the air hole connected to the gas joint is provided on the action surface. The air holes are used to spray high-pressure gas onto the second screen drum. The beneficial effect of the invention is that it can realize large-scale continuous screening operation, increase production and reduce costs, and ensure particle size parameters.

Description

technical field [0001] The invention relates to the field of fertilizer production, in particular to an anti-blocking and screening machine for compound fertilizer production. Background technique [0002] Most solid fertilizers need to be processed into granules. Fertilizer granulation is an important process in the fertilizer production process. The size and quality of granulation are related to the application effect of fertilizer. For the quality control of fertilizer granulation, its particle size distribution, strength, and uniformity are all important parameters. These parameters, like the content of fertilizer, become important contents of fertilizer quality standards. [0003] In use, the granular material is mainly mixed with the soil, or buried under the soil, and gradually releases the fertilizer effect. This requires higher requirements on the particle size of the granules. An appropriate particle size can not only ensure the expected dissolution and slow-rele...

Problems solved by technology

Commonly used equipment now includes multi-layer circular vibrating screens, etc., but the existing equipment cannot achieve continuous, efficient, and high-quality production in production. The main reasons include:

[0004] The screening method of most vibrating equipment needs to stop feeding and discharging, which determines that it cannot achieve continuous production, and the energy consumption of starting and stopping is large, the loss of the motor is high, and the production time and energy consumption are high;

[0005] The particles that have just been granulated not only entrain many oversized agglomerates, but also entrain many small particles that have not been successfully granulated, as well as powder, and a small amount of moisture. In the screening section, this kind of complex raw material particles, Not only is the blockage problem common, it needs to be shut down and cleaned layer by layer, which is very troublesome and delays production, and powder and small particles are entrained in it, which also reduces product quality

[0006] In summary, the current equipment needs to be shut down for feeding and discharging, cleaning, maintenance, etc., resulting in limited production capacity, low production efficiency and high cost

And the screening quality is not good, the problem needs to be improved urgently
