Chemical liquid stirring and mixing device and method

Abstract

The invention discloses a chemical liquid stirring and mixing device. The device comprises a stirring barrel and a barrel cover and is characterized in that a cross rod is arranged at the upper part of the stirring barrel; a bearing seat is arranged at the center of the cross rod; and the upper part of a stirring rod is arranged in a bearing of the bearing seat in a penetrating manner; and a convex cavity is formed in the middle portion of the barrel cover. The chemical liquid stirring and mixing device further comprises a lifting device, wherein the lifting device is provided with a lifting arm, the lifting arm is fixedly connected with the barrel cover, and a shell of the lifting device is fixedly connected with the stirring barrel through a connecting strip. According to the chemical liquid stirring and mixing device, the barrel cover and the stirring barrel can be separated, so internal parts of the stirring barrel are easy to maintain when the barrel cover is opened; the lifting device lifts the barrel cover in an automatic mode, so the burden of manual operation can be effectively reduced; and liquid is pumped from the stirring barrel, enters the stirring rod through a waterinlet jacket and is finally discharged from the horizontal stirring rod, so the liquid mixing effect is better.

Description

Technical field[0001]The present invention relates to a chemical apparatus, specifically a chemical liquid stirring mixing apparatus and method.Background technique[0002]During the chemical production process, there is a need to mix a plurality of liquids in a case where a plurality of liquids are mixed. When the liquid is more difficult to solve the agitation mixing capacity of the stirring mixing device, a high requirement is presented.[0003]The current chemical liquid stirring mixing device, including the mixing tank and the bucket cover, the mixing barrel, which is provided with a rotatable stirring rod, a stirring structure, a stirring structure, a tube cover, a tube, and a stirrer The tube is provided with a stirring motor, and the stirring motor is directly formed with a stirring rod, which is usually provided on the motor shaft of the stirring motor and the stirring lever, which is firmly connected. It is more inconvenient during post-maintenance. If you want to clean the in...

AI Technical Summary

Problems solved by technology

[0003] The current chemical liquid mixing device includes a mixing tank and a tank cover. There is a rotatable stirring rod in the mixing tank, a stirring structure is arranged on the stirring rod, and a feeding pipe is provided on the tank cover; There is a stirring motor on the material tube and the barrel cover, and the stirring motor directly forms a fixed transmission connection with the stirring rod. Usually, a coupling is set on the motor shaft of the stirring motor and the stirring rod is firmly connected. This way It is inconvenient for maintenance in the later stage. If it is necessary to clean the inner wall, it is difficult to open the lid completely. For example, Chinese patent 2018202031281 has this technical problem in a fine chemical material stirring device.

[0004] Chinese patent 201720108408.X is a chemical material mixing equipment with a lifting device. The stirring rod and the motor on the lid are integrated. In this way, the lid is very heavy when opened, and the structure is complicated. It requires a lot of manpower for maintenance. People work at the same time, it is very laborious

[0005] In addition, in order to improve the stirring and mixing effect, the existing stirring and mixing devices generally pay attention to and improve the structure of the stirring rod, such as Chinese patent 201720627991.5. The stirring plate in a new type of chemical mixing tank adopts a special structure of the stirring plate. In fact, the ability to stir and mix has limited improvement
