Abstract
The utility model relates to a mining explosion-proof diesel engine specifically indicates a turbine shell for mining explosion-proof diesel engine. The water inlet and the water outlet are communicated with the water channel, the air inlet and the air outlet are communicated with the air channel, and the outer shell is further provided with an exhaust hole which is communicated with the water channel. The exhaust holes are arranged on the shell, so that when the pressure in the turbine shell is too high, partial gas in the turbine shell can be directly exhausted through the exhaust holes, thereby reducing the gas pressure in the turbine shell and ensuring the stable operation of the turbine shell; the inner shell and the outer shell are connected in an integrated casting forming mode, so that smooth circulation of water flow in the turbine shell is guaranteed, and local high temperature is avoided.
Description
Technical field
The utility model relates to anti-explosion diesel engine for mine, refers to particularly a kind of anti-explosion diesel engine for mine turbine case.
Background technique
The adoptable intake method of current anti-explosion diesel engine for mine comprise natural aspiration and turbosupercharging air-breathing, while adopting the air inlet of natural aspiration mode, the air quantity entering in firing chamber is little, cause burning insufficient, the peak output of diesel engine can not be brought into play like this, also the severe overweight that discharges pollutants can be made; Adopt the air-breathing mode air inlet of turbosupercharging to there will not be the problems referred to above, but for the air-breathing mode of turbosupercharging, gas collection in turbine case water channel, blocks up the too high generation gas of gas pressure in turbine case, can affect the normal use of turbine case.
Summary of the invention
The purpose of this utility model is just to provide the anti-explosion diesel engine for mine turbine case that a kind of technique is simple, reliability is high, can avoid the localized hyperthermia that in turbine case, the gas of the too high generation of gas pressure is stifled and cooling water circulates and freely do not cause in turbine case when adopting the air-breathing mode air inlet of turbosupercharging, improve the utilization efficiency of turbine case.
For achieving the above object, the designed anti-explosion diesel engine for mine of the utility model exhaust gas turbine shell, comprise and be provided with the inner casing of suction port, air outlet and air flue, the shell that is provided with water intake and water outlet, the water channel between inner casing and shell, described water intake and water outlet are all communicated with water channel, described suction port and air outlet are all communicated with air flue, its special way is, is also provided with exhaust port on described shell, and described exhaust port is communicated with water channel.
Further, described inner casing is connected with the mode of shell by integrally casting moulding.
The utility model has the advantage of: by exhaust port is set on shell, too high when turbine case internal pressure, by exhaust port, can directly drain portion gas in turbine case, thereby reduce the gas pressure in turbine case, guarantee its stable operation; Inner casing is connected with the mode of shell by integrally casting moulding, guarantees that current circulate in turbine case unimpeded, avoided localized hyperthermia.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-suction port, 2-air outlet, 3-air flue, 4-inner casing, 5-water intake, 6-water outlet, 7-shell, 8-water channel, 9-exhaust port.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As shown in the figure, the utility model comprises and is provided with the inner casing 4 of suction port 1, air outlet 2 and air flue 3, the shell 7 that is provided with water intake 5 and water outlet 6, the water channel 8 between inner casing 4 and shell 7, described water intake 5 and water outlet 6 are all communicated with water channel 8, described suction port 1 and air outlet 2 are all communicated with air flue 3, on described shell 7, be also provided with exhaust port 9, described exhaust port 9 is communicated with water channel 8.Too high when turbine case internal pressure, can directly will directly drain portion gas in turbine case, thereby reduce the gas pressure in turbine case, guarantee its stable operation.Wherein, described inner casing 4 is connected with the mode of shell 7 by integrally casting moulding.
Waste gas enters air flue 3 through suction port 1, at the interior generation eddy flow of air flue 3, then discharges through air outlet 2.Cooling water enters the water channel 8 of shell 7 inside through water intake 5, after circulating, from water outlet 6, discharge.Because the cooling surface temperature of shell that makes of circulating water is lower than 150 ℃, meet explosion-proof criteria requirement.
