Pusher of discharging cooler for producing potassium sulphate chemical fertilizer by using Mannheim furnace

Abstract

The invention discloses a pusher of a discharging cooler for producing a potassium sulphate chemical fertilizer by using a Mannheim furnace, and belongs to the technical field of the production of the potassium sulphate chemical fertilizer. The pusher adopts an integrated structure, and comprises corrosion-resistant alloy materials arranged at the outer part and a silicon carbide ceramic block body embedded in the corrosion-resistant alloy materials, and is provided with a material pushing end and a welding end, wherein the material pushing end is used for pushing out the potassium sulphate chemical fertilizer entering a discharging cooler; and the welding end is welded to a main shaft in the discharging cooler. The pusher disclosed by the invention is used in the producing process of the potassium sulphate chemical fertilizer, can resist electrochemical corrosion and the destruction of physical abrasion; and the service life can completely meet the production run cycle; the production efficiency is greatly improved, the energy sources are also saved, and the production cost is reduced; and the pusher is an ideal main component of the production equipment for the potassium sulphate chemical fertilizer.

Description

technical field [0001] The invention relates to the technical field of potassium sulfate fertilizer production, in particular to a pusher for a discharge cooler used in the production of potassium sulfate fertilizer by a Mannheim furnace. Background technique [0002] At present, in the vast rural areas, the phenomenon of soil compaction is relatively common, and the reason is mostly related to the large-scale application of chemical fertilizers. Among the compound fertilizers currently used, potassium chloride is mostly used as potassium fertilizer. Long-term application of this chemical fertilizer will not only be harmful to certain crops, but also It will cause compaction of the soil. [0003] Potassium sulfate fertilizer is a high-quality chlorine-free potassium fertilizer. It can be used as a potassium fertilizer for avoiding chlorides in tobacco, sugar beets, and fruits. At the same time, it can provide two nutrients, potassium and sulfur, for crops. Improve agricultu...

Problems solved by technology

At present, the traditional general-purpose pusher, due to the lack of understanding of the production environment and process of potassium sulfate fertilizer, is not clear about its corrosion mechanism, so it blindly pursues the corrosion-resistant alloy with high cost. In fact, the selected alloy material, It is difficult to resist its electrochemical corrosion and physical abrasion, coupled with improper design of shape and size, resulting in serious corrosion of the pusher, short operating time and low production efficiency

A newly installed pushing device, the continuous use period of the general state is only 3-6 months (such as figure 1 ), under special conditions, the phenomenon that the continuous service life is only more than one month often occurs, so production must be stopped for replacement, which directly affects the production efficiency and output of potassium sulfate fertilizer, greatly increases production costs, and the replacement environment is extremely harsh and labor-intensive great
