Slurry filtering device and method

Abstract

The invention provides a slurry filtering device and method. The slurry filtering device comprises slurry pipes and is characterized in that the slurry pipes are connected with a discharge device, theslurry pipes include a main slurry pipe and at least two auxiliary slurry popes, the two opposite ends of the auxiliary slurry pipes are connected with the main slurry pipe, each auxiliary slurry pipe is provided with at least one filtering part, each filtering part comprise a shell and a filter screen radially arranged in the shell, each shell is movably connected with the corresponding auxiliary slurry pipe, each filter screen separates the inside of the corresponding shell into a feeding area and a discharge area, the corresponding shell of each feeding area is provided with a feed inlet,and the corresponding shell of each discharge area is provided with a discharge outlet. The slurry filtering device has the advantages that each auxiliary slurry pipe is provided with at least one filtering part, the slurry pipes include the main slurry pipe and at least two auxiliary slurry pipes, impurities in slurry can be filtered effectively, continuous production can be guaranteed, and the quality and production speed of granular fertilizer are increased.

Description

technical field [0001] The invention belongs to the technical field of fertilizer production, and in particular relates to a slurry filtering device and a slurry filtering method. Background technique [0002] Compound fertilizers have been widely used in agricultural production in my country because of their excellent performance. However, in the production process of compound fertilizers, impurities will inevitably exist during the melting or configuration of slurry. In the process of distributing the slurry containing impurities, the slurry will be ejected from the discharge opening of the discharge device, but impurities often accumulate and block the discharge opening, so that the slurry cannot be ejected. Finally, the preparation process cannot be carried out normally, which greatly improves the production cycle. [0003] In the prior art, the patent No. CN201721183984.7 discloses a slurry auxiliary transportation device, including a delivery pipe, several pressure se...

Problems solved by technology

However, the above-mentioned patents are not only complicated in operation and high in equipment cost, but also impurities still exist in the conveying pipe, which will still block the discharge port, and do not solve the problems mentioned in this application.
