Problems solved by technology
At present, the ventilation hole of the explosion-proof diesel engine crankcase should be equipped with a ventilation device, and a filter screen device is arranged in the ventilation device, so that it can prevent dust from polluting the crankcase and has a certain fire resistance. However, the existing explosion-proof diesel engine crankcase The ventilation device mostly adopts an integral structure. When the filter screen device needs to be replaced after a period of use, the entire ventilation device is often replaced, which causes a lot of waste and increases maintenance costs.

The invention discloses a crankcase ventilating device for an explosion-proof diesel engine. The crankcase ventilating device comprises a first shell, a second shell and a filter net device, wherein one end of the first shell is open, and the other end is connected with a first ventilating connector; one end of the second shell is open, and the other end is connected with a second ventilating connector; the open ends of the first and second shells are in detachable tight fit; after the first and second shells are connected, an accommodating cavity is formed between the first shell and the second shell; the middle of the accommodating cavity is provided with the filter net device; the first ventilating connector is connected with a breather pipe of a crankcase. The crankcase ventilating device for the explosion-proof diesel engine adopts a split detachable tight fit mode of the first and second shells; when a filter net is required to be replaced, the first and second shells are only required to be detached, the filter net is convenient to replace, the maintenance cost is reduced, and the installation is convenient; meanwhile, the crankcase ventilating device is high in fire retardance and good in explosion-proof performance.
Description
technical field [0001] The invention relates to an explosion-proof diesel engine, in particular to an explosion-proof diesel engine crankcase ventilation device. Background technique [0002] Explosion-proof diesel engines originated in the mining industry. With the improvement of people's safety awareness, various countries began to implement mandatory explosion-proof standards. This measure greatly accelerated the development of the explosion-proof industry, and correspondingly, the explosion-proof requirements for explosion-proof diesel engines are also getting higher and higher. At present, the ventilation hole of the explosion-proof diesel engine crankcase should be equipped with a ventilation device, and a filter screen device is arranged in the ventilation device, so that it can prevent dust from polluting the crankcase and has a certain fire resistance. However, the existing explosion-proof diesel engine crankcase Most of the ventilation devices adopt integral struct...
