Mine cement foaming machine

Abstract

The invention relates to a mine cement foaming machine which comprises a stand, a cement slurry conveying mechanism and a hydraulic system, wherein an explosion-proof motor is installed on the stand and is used for simultaneously driving a foaming plunger pump and a micropump; an output pipe of the foaming plunger pump is communicated with a foam producing device; an output shaft of the explosion-proof motor is used for also driving an air compressor; an output air pipe of the air compressor is communicated with the foam producing device; and the foam producing device passes through a pipeline and is communicated with the output pipe of the cement slurry conveying mechanism after a valve is installed. The invention can be suitable for mine operation and is capable of rapidly constructing walls in an underground tunnel, such as a windbreak wall, and the like and has time saving, labor saving and high working efficiency. The whole machine adopts a manual control valve or a mechanical control valve, meets the mine working condition, has the advantages of safety, reliability, convenient use and easy manufacture or reformation, is suitable for mass production and is quite beneficial to popularization and construction.

Description

Technical field: [0001] The invention relates to a cement foaming machine used in the field of mining safety, in particular to a cement foaming machine for underground use. Background technique: [0002] At present, the windbreak walls or firewalls built in mines are built in ordinary masonry methods, which is time-consuming and labor-intensive, and the efficiency is low. The body of wall that is piled up with sand by cloth tape has the defects of poor sealing and poor firmness. Cement pouring walls can meet the above deficiencies, but the current cement foaming machines are not suitable for underground operations. Moreover, there is still a certain gap in the foaming performance of the existing foaming machine, which needs to be further improved. For example, the existing problem is that the bubbles are rarely generated. More importantly, the size of the foam is uneven, which affects the stability and strength of the foam, and the amount of foam produced is very random an...

Problems solved by technology

[0002]At present, the windbreak wall or firewall built in the mine is constructed by ordinary masonry, which is time-consuming and laborious, and the efficiency is low

The walls built with cloth and sand have the defects of poor sealing and poor firmness

Cement pouring walls can meet the above deficiencies, but the current cement foaming machines are not suitable for underground operations

Moreover, there is still a certain gap in the foaming performance of the existing foaming machines, which needs to be further improved. For example, the existing problem is that the bubbles are rarely generated.

The more important thing is that the size of the foam is uneven, which affects the stability and strength of the foam, and the amount of foam produced is very random and difficult to control
