Novel stirring kettle with stirring shaft capable of being conveniently replaced

Abstract

The invention provides a novel stirring kettle with a stirring shaft capable of being conveniently replaced. The novel stirring kettle comprises a stirring kettle body, wherein the stirring shaft is arranged in the center of the stirring kettle body; the top end is tightly clamped by a clamping device; in addition, a stirring paddle is arranged on the stirring shaft; the clamping device comprises a clamp head, a bearing, a push sleeve, a guide rod, a locking plate, an air cylinder and a piston; the clamp head comprises a clamping part formed by a rotating rod and two clamp heads; each clamping head is a circular arc plate with the semicircular cross section; the outer side of the end part connected with the rotating rod is a conical surface; a through hole matched with the rotating rod is formed in the push sleeve; inner cone holes matched with the outer conical surfaces of the clamping heads are formed in the locking plate; the rotating rod is connected into the through hole of the push sleeve in a penetrating way; the clamping part is arranged in the inner cone hole of the locking plate; the guide rod is arranged on the push sleeve. The novel stirring kettle has the advantages that the problem of high replacing difficulty of the stirring shaft is solved; the problem that whether the stirring shaft and a motor are concentric or not does not need to be considered; the stirring paddle realizes the vertical convection of the materials; the materials attached onto the inner wall of the stirring kettle can be effectively stirred and scraped; the stirring efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of circuit board clamping, in particular to a circuit board processing and clamping device. Background technique [0002] Stirring kettle is a kind of shaft with blades that rotates in a cylinder or a tank to stir and mix various raw materials. It is a fluid mechanical product with a wide range of applications and a wide variety. It is suitable for the fields of chemical industry, metallurgy, medicine, food and feed, etc. . Stirring operation is an important part of the industrial reaction process. Its principle involves various processes such as fluid mechanics, heat transfer, mass transfer and chemical reaction, and the agitator is to input mechanical energy to the stirring medium to obtain a suitable flow field. device.

AI Technical Summary

Problems solved by technology

[0003] At present, the diameter of the existing stirring blades is generally welded to the stirring shaft. During the long-term stirring process, the stirring blades are subjected to a large force and are prone to breakage, which affects the stirring efficiency. Therefore, it is necessary to take out the stirring shaft from time to time. For maintenance and replacement of the paddle, the stirring shaft needs to be separated from the motor, which is difficult to replace. At the same time, the concentricity of the stirring shaft and the motor needs to be considered after installation, which is time-consuming and laborious
