Problems solved by technology
Existing explosion-proof diesel engines have certain disadvantages: first, because the nozzle at one end of the water interlayer exhaust pipe of the exhaust system is connected to the nozzle at one end of the water interlayer corrugated pipe, the exhaust gas discharged from the diesel engine body enters into the water interlayer corrugated pipe. The path of the pipe is long, the airflow needs to turn, the resistance of the exhaust is large, the exhaust efficiency is low, and the power consumption is large; secondly, because the water outlet joint of the water interlayer bellows of the exhaust system is connected with the cylinder head water jacket of the diesel engine body , the water inlet joint of the water interlayer bellows is connected with the water outlet joint of the water interlayer exhaust pipe, and the water inlet joint of the water interlayer exhaust pipe is connected with the cylinder water jacket of the diesel engine body. When in use, once the water in the exhaust gas treatment box is consumed Too much water or water leakage will lead to insufficient cooling water in the cylinder body of the diesel engine body. If the cylinder block of the diesel engine is not sufficiently cooled, the body of the diesel engine will overheat and easily damage the cylinder block, making it unable to work normally.
In addition, the waterway connection method of this exhaust system has a complex structure and is inconvenient to maintain; thirdly, the air intake explosion-proof fence is directly installed on the air intake pipeline of the air intake system, so that the installation, replacement and cleaning of the air intake explosion-proof fence are not easy. Convenient, difficult to assemble

The invention discloses an explosion proof diesel engine which comprises a diesel engine body, an air inlet system and an exhaust system, wherein an air inlet of an air inlet pipe and an air inlet of a water interlining exhaust pipe are respectively communicated with an air inlet and an air outlet of the diesel engine body, an air outlet of the water interlining exhaust pipe is arranged in the middle of a pipe body, and an axial line of the air outlet is substantially parallel with of the axial lines of a plurality of air inlets; a water inlet of the water interlining exhaust pipe is communicated with a water supplementing tank, a water outlet thereof is communicated with a water inlet of a water interlining corrugated pipe, a water outlet of the water interlining corrugated pipe is communicated with a water inlet of a waste gas treatment tank, and a ball float valve is arranged in the waste gas treatment tank; a waste gas exhaust pipe is connected to a waste gas outlet of the waste gas treatment tank, and a waste gas explosion proof fence is also installed between the waste gas outlet and the waste gas exhaust pipe; and the air inlet system also comprises a gas inlet tank, wherein an outlet of the gas inlet tank is communicated with an inlet of a gas inlet corrugated pipe, and an air inlet explosion proof fence is inserted into the gas inlet tank. The invention has the advantages of less exhaust resistance and reasonable waterway connection of the exhaust system; and the air inlet explosion proof fence is conveniently installed and replaced.
Description
technical field [0001] The invention relates to a diesel engine, in particular to an explosion-proof diesel engine. Background technique [0002] At present, explosion-proof diesel engines are generally used in explosive places such as underground coal mines to provide power for mechanical operations such as transportation and loading. Existing explosion-proof diesel engines have certain disadvantages: first, because the nozzle at one end of the water interlayer exhaust pipe of the exhaust system is connected to the nozzle at one end of the water interlayer corrugated pipe, the exhaust gas discharged from the diesel engine body enters into the water interlayer corrugated pipe. The path of the pipe is long, the airflow needs to turn, the resistance of the exhaust is large, the exhaust efficiency is low, and the power consumption is large; secondly, because the water outlet joint of the water interlayer bellows of the exhaust system is connected with the cylinder head water ja...
