Extraction tank stirrer

Abstract

The invention discloses an extraction tank stirrer. The stirrer comprises a stirring shaft (1) and is characterized in that the upper layer of the stirring shaft (1) is provided with an impeller (2), the impeller (2) comprises a square wheel hub (25), which is fixed on the stirring shaft (1) and a blade (21); the blade (21) is fixed on the square wheel hub (25) through a connection flange (23); the upstream face of the blade (21) is a streamline curved surface, so that the stirrer can push fluid to a longer distance under a same push force; and the tail end of the blade (21) is provided with a cylindrical current stabilizing ring (211), which can reduce the deflection of the stirring shaft (1) and improve the stirring stability. The provided extraction tank stirrer has the advantages that the materials are overturned for many times during the rotation process of the stirring shaft, the stirring is table, the stirring effect is good, and the extraction tank stirrer is especially suitable for materials with a high solid content. Moreover, the blade angle can be adjusted, and the parts can be changed easily, so the extraction tank stirrer can be promoted and used.

Description

technical field [0001] The invention relates to the technical field of stirring, in particular to an extraction tank stirrer with stable and high-efficiency stirring, convenient parts replacement and adjustable blade angle. Background technique [0002] With the continuous development of the industry, users have higher and higher requirements for the overall stability, high efficiency and standardization of equipment accessories of the agitator. At present, the agitator cannot meet the increasingly high requirements of users. [0003] The non-streamlined curved surface design of the agitator blades leads to low liquid discharge, and often has to be equipped with high-power motors, which increases operating costs; the poor stability of the agitator blades causes the agitator shaft to shake, and over time causes the agitator support bearings to be broken, which makes the user's repair and maintenance Increased costs. Generally, a set of agitators is only for one process, and ...

Problems solved by technology

[0003] The non-streamlined curved surface design of the agitator blades leads to low liquid discharge, and often has to be equipped with high-power motors, which increases operating costs; the poor stability of the agitator blades causes the agitator shaft to shake, and over time causes the agitator support bearings to be broken, which makes the user's maintenance difficult Increased costs

Generally, a set of agitators is only for one process, and the versatility is not strong. Some users need to purchase a new set of agitators due to production needs to adjust the process and change the types of products produced, resulting in low equipment utilization.

The non-standard design of the agitator blades leads to many types of blades, which brings trouble to the user for spare parts, and the cost of spare parts is relatively high
