Space-saving coal mine internal combustion engine heater

Abstract

The invention belongs to the technical field of internal combustion engine heaters, and particularly discloses a space-saving coal mine internal combustion engine heater which comprises a shell, the interior of the shell is divided into a first cavity and a second cavity through a partition plate, and a first combustion chamber and a second combustion chamber are arranged in the first cavity and the second cavity respectively; two air inlet pipes and two air outlet pipes are arranged at the two ends of the shell correspondingly, and the ends, away from the shell, of the two air inlet pipes and the ends, away from the shell, of the two air outlet pipes communicate with an air inlet flow dividing pipe and an air outlet collecting pipe correspondingly. The side, away from the air inlet pipe, of the air inlet flow dividing pipe communicates with an air inlet, a draught fan is installed in the air inlet, and a dustproof mechanism is arranged at an end opening of the air inlet and fixed through fixing mechanisms symmetrically arranged at the upper end and the lower end of an air outlet. According to the invention, cab warm air and engine heating can be realized at the same time, and dust is not easy to introduce into equipment when the heater operates.

Description

technical field [0001] The invention relates to the technical field of internal combustion engine heaters, in particular to a space-saving coal mine internal combustion engine heater. Background technique [0002] The heaters currently on the market are all single combustion chambers, but for large internal combustion engine equipment in open-pit coal mines, the heat generated by combustion in the combustion chamber not only provides heat for heating the coolant, but also provides heat for the warm air in the cab, while large internal combustion engines The amount of coolant inside the engine in the equipment is very large, and it is generally impossible to provide heat to the cab warm air when it is heated, otherwise it will affect the low heating efficiency of the coolant. Therefore, it is impossible to provide heat for the cab warm air and coolant heating heat; foreign countries have larger power heaters, but they take up a lot of space and cannot be installed on internal...

Problems solved by technology

[0002] The heaters currently on the market are all single combustion chambers, but for large internal combustion engine equipment in open-pit coal mines, the heat generated by combustion in the combustion chamber not only provides heat for heating the coolant, but also provides heat for the warm air in the cab, while large internal combustion engines The amount of coolant inside the engine in the equipment is very large, and it is generally impossible to provide heat to the cab warm air when it is heated, otherwise it will affect the low heating efficiency of the coolant. Therefore, it is impossible to provide heat for the cab warm air and coolant heating heat; foreign countries have larger power heaters, but they take up a lot of space and cannot be installed on internal combustion engine equipment with a compact structure and small space; in addition, when the existing coal mine internal combustion engine heaters introduce air, it is easy to introduce dust in the air inside the device
