Description

Novel alkali material feeding system

Technical Field

A novel alkali material feeding system belongs to the technical field of alkali material storage and conveying equipment.

Background

The liquid caustic soda is a liquid caustic soda product produced by a caustic soda production device by taking original salt as a main raw material, contains a large amount of floating salt, and when the liquid caustic soda is sent into a liquid caustic soda storage tank for storage, floating salt particles can settle due to the action of gravity and are precipitated at the bottom of the tank. The floating salt precipitation is increased along with the increase of the liquid caustic turnover. The inlet line of the liquid caustic soda conveying pump is positioned at a position 300mm above the bottom of the tank at the interface of the storage tank, and with the increase of floating salt, part of floating salt is brought into the pipeline and the pump by the flow of the liquid caustic soda, so that a filter at the inlet of the pump is blocked, even the pump body is blocked, and the pump cannot be started normally; and liquid caustic soda delivery pump inlet line is located the tank bottoms more than 300mm department at the storage tank interface, along with the increase of floating salt, when the floating salt height that deposits in the jar is close 300mm, can block up pump inlet line, causes unable pump delivery truck to dispatch from the factory, influences normal production and goes on. About 45 days or so, the condition that the pipeline is blocked by the precipitated floating salt can happen, so that the floating salt must be cleaned by cleaning the tank, and a large amount of manpower and material resources are wasted.
