cement foam machine mixer

Abstract

The invention discloses a cement foaming machine mixer. The end of the mixer shell is provided with an end cover, the front end of the mixer shell is provided with a tapered discharge port, and the inner wall of the mixer shell is along the There is a conical anti-retreat step in the circumferential direction, and a conical baffle is provided at the conical anti-retreat step, and the inner cavity of the mixer shell is divided into a mixing chamber and a feeding chamber through the conical baffle. There is an air pipe on the conical surface baffle on one side of the feed chamber, and the other end of the air pipe is led out from the side wall at the end of the mixer shell and connected with the foaming agent air pump. There are air holes evenly distributed on the air pipe in the horizontal direction. The conical surface baffle on the outside of the air pipe is provided with discharge holes connecting the feeding chamber and the mixing chamber, and at least two distribution baffles are arranged in the mixing chamber, and the distribution baffles are evenly distributed with distribution holes. And the distributing holes on the adjacent distributing baffles are arranged in dislocation. The invention utilizes an air pump to fully mix the cement and the foaming agent to achieve better foaming effect, and the prepared foamed cement meets the national standard.

Description

technical field [0001] The invention belongs to the technical field of foam cement production equipment, and in particular relates to a cement foam machine mixer. Background technique [0002] The unit's invention patent, the patent number is ZL 201320156977.3, and the name is a kind of equipment for producing foamed cement. In the later stage of the test, the foamed cement produced by the equipment has the problems of high density of foamed cement and overweight per unit weight. The reason is that the foaming agent and the cement slurry are not fully mixed, so that the cement solution does not reach the maximum foaming volume before solidification. After cutting and observing, it is found that some foaming pores in the cement are very small, and even hard lumps appear. In some parts, the foaming effect is better, and the pores are large and uniform. The reason for the above situation is that the air bubbles emitted before the cement pouring are not fully mixed with the ceme...

[0002] The unit's invention patent, the patent number is ZL 201320156977.3, and the name is a kind of equipment for producing foamed cement. In the later stage of the test, the foamed cement produced by the equipment has the problems of high density of foamed cement and overweight per unit weight. The reason is that the foaming agent and the cement slurry are not fully mixed, so that the cement solution does not reach the maximum foaming volume before solidification. After cutting and observing, it is found that some foaming pores in the cement are very small, and even hard lumps appear. In some parts, the foaming effect is better, and the pores are large and uniform. The reason for the above situation is that the air bubbles emitted before the cement pouring are not fully mixed with the cement mixture. If this situation can be effectively avoided, the above situation can be effectively avoided Therefore, it is necessary to develop a cement foaming machine mixer to effectively solve the above technical problems
