Abstract

The invention discloses a compound fertilizer slurry centrifugal filter using a melt method. The compound fertilizer slurry centrifugal filter comprises a barrel body assembly, wherein a filtering mechanism is horizontally arranged inside the barrel body assembly; a residue clearing device is coaxially arranged in an inner cavity of the filtering mechanism; a feeding pipe is arranged at a feeding port end of the residue clearing device; the filtering mechanism is in independent transmission connection with a filtering mechanism transmission system; the residue clearing device is in independent transmission connection with a residue clearing transmission system; the lower part of the filtering mechanism leads to a finished product discharging port; and the lower part at the tail end of the residue clearing device leads to a waste material discharging port. The compound fertilizer slurry centrifugal filter is high in flow velocity of slurry, high in automatism, low in labor intensity of working staff, large in filtering area, and easy to clean, operate and maintain.

Description

technical field [0001] The invention belongs to the technical field of chemical equipment and relates to a centrifugal filter for compound fertilizer slurry by melt method. Background technique [0002] In the production process of compound fertilizer (or mixed fertilizer) produced by melt method, before the granulation (or pump injection) process, it is necessary to filter the mixed slurry to completely remove the slag in the slurry. It can make the granulation production process go smoothly, otherwise, it will easily cause the blockage of the granulator or spray gun, which will affect the normal production process. [0003] When filtering the above-mentioned slurry in actual production, the existing filter mainly uses stainless steel wire mesh as a filter element to filter the above-mentioned slurry. The filter includes two methods: one is a fixed filter, and the other is a fixed filter. One is a rotary filter, which mainly has the following defects: [0004] 1) Fixed fi...
