The utility model comprises a double cylinder diesel engine, which is provided with an air inlet pipe and connected with the exhaust-gas treatment box through the air exhaust pipe. An air intake fence is disposed on the air inlet pipe of the double cylinder diesel engine, and the air exhaust pipe of the double cylinder diesel engine hasa double-layer water cooling structure. The exhaust-gas treatment box comprises a box body fulfilled with cooling water and an exhaust pipe disposed in the box body. The exhaust pipe is constituted by a first pipe, a second pipe sleeved on the outside of the first pipe, a third pipe fixedly sleeved on the outside of the first and second pipe, and a blind pipe with a closed end fixedly sleeved on the outside of the third pipe. An exhaust fence is disposed on the exhaust outlet of the exhaust-gas treatment box body. The double cylinder explosion proof diesel engine provided in the utility model can be used in the down-hole of the coal mine and dangerous working condition, especially can be used to provide power for the down-hole transport vehicles.
Description
Technical field
The utility model relates to diesel engine, is specially a kind of twin-tub anti-explosion diesel engine.
Background technique
At present haulage vehicle all is to be power with the single cylinder anti-explosion diesel engine under the coal mine, and along with the demand of down-hole to transport capacity constantly promotes, the single cylinder anti-explosion diesel engine is little because of air displacement, the little demand that can't satisfy the down-hole transportation of power.Existing two cylinder diesel engine can not be directly used under the coal mine because of not having explosion prevention function.And the single cylinder anti-explosion diesel engine is because air displacement is smaller, the blasting resistance structure of therefore existing single cylinder anti-explosion diesel engine can't be applicable to the twin-tub anti-explosion diesel engine again, be in particular in: 1, exhaust piping in the waste gas treatment case of single cylinder anti-explosion diesel engine is shorter, do not disconnect in the middle of the pipeline, waste gas in the waste gas treatment case directly is discharged in the cooling water from pipeline, cooling water water smoke state is not so good, waste gas circulates in case, washing, the time of cooling is short, cause excessive discharge temperature, part waste gas hangs direct the eliminating outside the case the box body from bend pipe in the exhaust process in the waste gas treatment case simultaneously.2, the outlet pipe of single cylinder anti-explosion diesel engine does not have cooling structure, and when becoming twin-tub by single cylinder, air displacement increases, and Tail Pipe Temperature is too high, is unfavorable for explosion-proof.3, the relief opening of the suction tude of diesel engine and waste gas treatment case does not have blasting resistance structure, after single cylinder becomes twin-tub, along with the raising of diesel engine power, air inflow and air displacement and delivery temperature all increase to some extent, so the blasting resistance structure on the relief opening of suction tude and waste gas treatment case just becomes necessary.
Summary of the invention
The utility model can't be applicable to the twin-tub anti-explosion diesel engine for the blasting resistance structure that solves the single cylinder anti-explosion diesel engine, so two cylinder diesel engine can not be directly used in the problem under the coal mine, and a kind of twin-tub anti-explosion diesel engine is provided.
The utility model is to adopt following technological scheme to realize: the twin-tub anti-explosion diesel engine, comprise two cylinder diesel engine, and be connected with suction tude on the two cylinder diesel engine, two cylinder diesel engine is connected with the waste gas treatment case by outlet pipe; The suction tude of two cylinder diesel engine is provided with the air inlet fence; The outlet pipe of two cylinder diesel engine is double-deck water-cooling structure, and its waterway communicate with the cool cycles water route of two cylinder diesel engine (be the recirculated cooling water of cooling water and diesel engine in the waterway be in series and circulate jointly); Described waste gas treatment case comprises casing and the interior exhaust piping of casing that is filled with cooling water, exhaust piping is fixed in first pipe outer second pipe, cover by first pipe, cover and is fixed in the blind pipe that the 3rd outer pipe of first pipe and second pipe and cover be fixed in the outer end closure of the 3rd pipe and constitutes, and the relief opening of the casing of waste gas treatment case is provided with the exhaust fence; Described air inlet fence and exhaust fence comprise upper and lower frame, upper and lower frame both sides and preceding frame and the after-frame fixed with frame, be installed with stud bolt on the upper and lower frame, be installed with the grid sheet on the screw rod of stud bolt, be provided with pad on the screw rod that is placed in bolt (thickness of pad is exactly the gap between the grid sheet---fence gap) between the adjacent gate sheet.The relief opening of the casing of suction tude and waste gas treatment case is set up fence and is helped improving explosion-proof ability.Outlet pipe adopts double-deck water-cooling structure can fully reduce the temperature of outlet pipe, helps explosion-proof.Exhaust piping in the waste gas treatment case disconnects in waste heat box, be used for changing aqueous vapor moving direction and cause the water smoke of kilter that waste gas is repeatedly circulated at cooling water, fully circulation cooling, tail gas is not directly discharged, all gas all passes through washing fully, discharge the cooling back, greatly reduce the exhaust gas discharging temperature, improve explosion-proof reliability; Because the diameter of each pipe increases successively, help reducing the exhaust gas discharging resistance simultaneously.
Twin-tub anti-explosion diesel engine described in the utility model by rational blasting resistance structure design, makes two cylinder diesel engine possess explosion prevention function on the basis of two cylinder diesel engine, its explosion-proof performance safety, stable, and economic benefit is higher, uses comfortable, easy, reliable.This twin-tub anti-explosion diesel engine is applicable under the coal mine and dangerous operating environment, is applicable to specifically in the explosive gas atmospheres such as having gas and coal dust, is particularly suited for the power as haulage vehicle under the coal mine.
