Problems solved by technology

[0002] When the internal combustion engine equipment in open-pit coal mines works in winter, it needs to heat the antifreeze around the heater through the heat generated by the heater burning diesel oil, and rely on the circulating water pump to send the antifreeze to the cab air conditioning system or the engine cylinder liner to provide the cab. Warm air, and can make the engine hot start, reduce

Abstract

The invention belongs to the technical field of internal combustion engines, and particularly discloses a coal mine internal combustion engine heater heat recovery system which comprises a heater shell and a cooling liquid storage box located at the top of the heater shell. An air inlet is formed in the left end of the heater body, a steel cylinder is arranged in the heater shell, a combustion chamber is arranged in the steel cylinder, a mixing chamber is arranged at the position, on one side of the steel cylinder, in the heater shell, and a combustible inlet is formed in the top of the heater shell; a cooling liquid containing cavity is formed in the steel cylinder, and the cooling liquid containing cavity communicates with the cooling liquid storage box through a first cooling liquid circulation pipeline and a second cooling liquid circulation pipeline. Exhaust channels which are communicated with each other are formed in the two ends of the steel cylinder, the ends, facing the mixing chamber, of the exhaust channels are communicated with a collecting ring through connecting pipes, an exhaust pipe is arranged at the bottom end of the collecting ring, and the bottom end of the exhaust pipe extends out of the heater shell and is connected with an exhaust silencing assembly; the heat recovery effect is good, and noise and air pollution are not likely to be caused.

Description

Technical field [0001] The present invention relates to the field of internal combustion engines, in particular a heat recovery system of a coal mine internal combustion engine heater. Background technique [0002] In the winter operation, the open-air coal mine is in winter, it is necessary to heat the antifreeze surrounding the heater by the heat generated by the heater, relying on the circulating water pump to send antifreeze to the cab air conditioning system or engine cylinder set, to provide the cab Heating, and can cause the engine heat to reduce the wear of the engine in winter, but the existing coal mine internal combustion engine heater heat recovery system is only one heat exchange, the heat exchange effect is poor, and the gas temperature of its last discharged gas Still higher, causing heat loss; in addition, the heater is discharged to the gas and air pollution when the heater is combusted. Inventive content [0003] It is an object of the present invention to prov...
