Description

Chemical mixing tank Technical Field The utility model relates to a mixing tank, in particular to a chemical mixing tank. Background In the production process of chemical industry, pharmacy industry, material industry and the like, the full mixing of chemicals is a key link for ensuring the quality and performance of products. Traditional chemical mixing tank adopts the structure of (mixing) shaft cooperation stirring paddle blade generally, through motor drive stirring part rotation, relies on the mutual collision of mechanical stirring power messenger's internal chemicals of jar, realizes mixing. However, the conventional mixing mode has obvious limitations that on one hand, the stirring blade can only drive the fluid in a local area to move, a mixing blind area is easy to form in the tank body, so that the chemical is unevenly mixed to influence the stability of a product batch, and on the other hand, the conventional mixing tank lacks a directional guiding and reinforced mixing mechanism for the fluid, so that the mixing efficiency is low, the production period is prolonged, and the energy consumption cost is increased. To enhance the mixing effect, some of the prior art attempts to improve the mixing performance by optimizing the shape of the stirring blade or increasing the number of stirring members, but such improvements simply adjust the fluid flow in the stirring area, and cannot fundamentally solve the problem of insufficient fluid exchange. Disclosure of utility model In view of the above, the present utility model provides a chemical mixing tank that effectively solves the problems mentioned in the background art. In order to achieve the above purpose, the utility model provides the following technical scheme that the utility model comprises the following steps: A tank body; A sealing cover fixed at the top end of the tank body, wherein one side of the sealing cover is rotationally connected with a charging cover; The stirring motor is arranged in the middle of the top end of the sealing cover; is arranged at the bottom end of the tank body a liquid discharge pipe at one side; a stirring shaft which is driven by a stirring motor and is rotatably arranged on the inner side of the tank body; a plurality of stirring blades uniformly distributed along the circumferential direction of the stirring shaft; And the auxiliary mechanism is arranged on the stirring She Duanbu and comprises an exchange piece fixed on the stirring She Duanbu, a liquid suction port is formed in the upper part of one side of the exchange piece facing the stirring direction, a liquid discharge port is formed in the lower part of one side of the exchange piece facing away from the stirring direction, and the liquid suction port and the liquid discharge port are communicated through a guide channel. Preferably, the device also comprises an inclined plane which is arranged in the liquid suction port and is used for obliquely guiding the channel. Preferably, the guide channel is inclined by 30-60 degrees from the bottom end of the liquid suction port to the direction of the liquid discharge port. Preferably, the inclined plane extends to the inlet of the guide channel to form an arc-shaped guide plate, and the curvature radius of the guide plate is 3-8mm. Preferably, spiral ribs are arranged on the inner wall of the guide channel at intervals, and the distance between adjacent ribs is 0.8-1.2 times of the diameter of the channel. Preferably, the exchange member adopts a plate-like structure. The directional fluid circulation has the beneficial effects that the exchange piece of the auxiliary mechanism forcedly guides chemicals to be sucked from the liquid suction port and discharged from the liquid discharge port after passing through the guide channel by utilizing the pressure difference generated by stirring through the liquid suction port (facing to the upper part of the stirring direction) and the liquid discharge port (facing to the lower part of the stirring direction), so that cross-region fluid exchange is formed, and the local mixing limitation of the traditional stirring is broken. Turbulent flow enhanced mixing, namely, the spiral convex ribs (the distance is 0.8-1.2 times of the diameter of the channel) on the inner wall of the guide channel disturb the laminar flow state of the fluid, so that the turbulence degree is increased, the chemicals are secondarily mixed in the channel, and the overall uniformity is further improved. Fluid-directed optimization The inclined plane and the arc-shaped guide plate (the curvature radius is 3-8 mm) in the liquid suction port reduce the fluid resistance, guide chemicals to enter the guide channel rapidly, and improve the exchange efficiency. The 30-60 degree inclined design of the guide channel combines the action of gravity to assist the natural flow of fluid, so as to avoid the retention or deposition of materials in the channel.
