Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
The micro-pressurization system of a kind of bulldozer cab that the utility model provides; hazardous substances in outside air can be filtered by it; air after filtering is transported in driver's cabin; indoor supercharged to driving when carrying; the air pressure in driver's cabin is made to be greater than air pressure outside driver's cabin; thus the pernicious gas outside driver's cabin cannot be entered in driver's cabin, protect the air ambient in driver's cabin.
See Fig. 1, the micro-pressurization system of a kind of bulldozer cab that the utility model provides, it mainly comprises air cleaning unit 100, exhaust apparatus 200 and air duct 300.
Air cleaning unit 100, it is arranged on outside driver's cabin, and it is for filtering hazardous substances in driver's cabin outside air, being transported in driver's cabin, when carrying, can producing an air pressure by the cleaned air after filtering.
Air cleaning unit 100, comprise a housing, housing is specially integrated plastic shell, housing offers air intake and air outlet, three placing chambers are provided with in housing, be respectively equipped with air filter 110, negative oxygen ion strainer 120 and adjustable speed blast fan 130 in three placing chambers, air filter 110, negative oxygen ion strainer 120 and adjustable speed blast fan 130 specifically can be connected with the power supply in driver's cabin.
Air filter 110 and negative oxygen ion strainer 120 are to by air intake, the air entered in housing filters.
Adjustable speed blast fan 130, air after it is used to air filter 110 and negative oxygen ion strainer 120 filtration produces a wind direction air pressure, air after air filter 110 and negative oxygen ion strainer 120 are filtered is blown in driver's cabin by air outlet, and can strengthen the air pressure in driver's cabin.
Blow in driver's cabin for the ease of the air after air filter 110 and negative oxygen ion strainer 120 being filtered, the blowing direction of adjustable speed blast fan 130 is identical with the air-out direction of negative oxygen ion strainer with air filter.
In addition, conveniently operate, the utility model is also provided with a controller 400, controller 400 is specifically arranged in driver's cabin, it is connected with air filter 110, negative oxygen ion strainer 120 and adjustable speed blast fan 130 respectively, and it is for controlling air filter 110, the pattern of negative oxygen ion strainer 120 and the wind-force size of control adjustable speed blast fan 130.
Exhaust apparatus 200, it is specifically arranged on cabin interior, and it is the flow direction for controlling the air after air cleaning unit 100 filtration, and the air after filtering can be filled in driver's cabin by Quick uniform.
Air duct 300, it is laterally placed between driver's cabin and ceiling inside gadget, its one end is through the air outlet of air cleaning unit 100, be communicated with negative oxygen ion strainer 120 with air filter 110, the other end is connected with exhaust apparatus 200, and the air after such air cleaning unit 100 filters is transported in driver's cabin by air duct 300.
Here is specific works process of the present utility model:
When bulldozer works, first air filter 110, negative oxygen ion strainer 120 and adjustable speed blast fan 130 is opened by controller 400, air filter 110 and negative oxygen ion strainer 120 pairs of outside airs filter, cleaned air after filtering is blown in air duct 300 by adjustable speed blast fan 130, air duct 300 and exhaust apparatus 200 match, cleaned air is transported in driver's cabin, wherein a part of cleaned air can be retained in driver's cabin, and another part cleaned air can be let out by the micro gap of driver's cabin;
After conveying after a while, air pressure in driver's cabin can strengthen gradually, air pressure in driver's cabin can be greater than external atmosphere pressure gradually, along with the increase of room pressure, the air capacity discharged by gap also can correspondingly be increased, in this course, enter the state that air capacity in driver's cabin and the air capacity that discharges can reach a relative equilibrium gradually, the pressure differential inside and outside driver's cabin also can keep a substantially invariable numerical value;
Because the pressure in driver's cabin is higher than external atmosphere pressure all the time, all the time the high pressure draught outwards blown is had by the micro gap of driver's cabin, the gas that dust or noxious material are contained in such external world directly would not be entered in driver's cabin by micro gap, thus ensure that the clean and health in driver's cabin, be beneficial to the physical and mental health of driver.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and manual just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
