Abstract
The utility model discloses an oil-free air compressor. The oil-free air compressor is characterized in that a water drain valve is arranged at the bottom of an air storage tank, a filter device is arranged at a water inlet of the water drain valve, a water outlet of the water drain valve is connected with a hose, and a spray gun is arranged at the other end of the hose. As the water drain valve is arranged at the bottom of the air storage tank of the oil-free air compressor, deposited water in the air storage tank can be safely drained through the hose and the spray gun. Simultaneously, the deposited water can be utilized by the spray gun to be used for cleaning and cooling a pump head of the oil-free air compressor, the waste is recycled and resources are saved.
Description
Technical field
The utility model relates to air compressing field, and more particularly, it relates to a kind of oil-free air compressor.
Background technique
Air compressor is the device that the mechanical energy of former moving (normally motor) is converted to gas pressure energy, is compressed-air actuated pressure generator.
Air compressor produces form as a kind of important energy, be widely used in the links of life, especially be widely used in machinery, metallurgy, electricity under electric power, medicine, packing, change, numerous lower industry field such as food, mining, weaving, traffic, become compressed-air actuated main product.
Oil-free air compressor is air compressor to without oily zero-emission, non-environmental-pollution, the energy-conserving and environment-protective achievement of transition, is the main selection type of air compressor development ultimate aim.Oil-free air compressor is in the time of operation, due to by air compressing in gas holder, airborne water vapour forms water droplet, especially higher at southern relative air humidity, in gas holder, have a large amount of ponding, oil-free air compressor in the market arranges a drain opening in gas holder bottom again, in the time of draining, need manually the lid in drain opening to be outwarded winding, this is inconvenient operation but also because gas holder internal air pressure is larger not only, all be easy to be subject to the impact of high pressure draught at an instant lid of outwarding winding and hand, cause unnecessary injury, therefore not only complex operation of this drainage pattern, also there is certain potential safety hazard, ponding is emitted in vain simultaneously, cause the serious wasting of resources.
Model utility content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of oil-free air compressor, can not only solve the drainage problem in cylinder by set spray gun, this ponding can also be used, for this oilless air compressor has increased cleaning, cooling function.
For achieving the above object, the utility model provides following technological scheme: a kind of oil-free air compressor, comprise gas holder and pump head, described pump head is arranged on gas holder, between gas holder and pump head, be connected by breathing pipe, the below of described gas holder is provided with castor, described gas holder bottom is fixedly connected with drain valve, described drain valve and gas holder internal communication, the water intake of described drain valve is provided with filtrating equipment, the water outlet of described drain valve is connected with flexible pipe, and the other end of flexible pipe is equipped with spray gun.
The utility model is further set to: described filtrating equipment is filter screen.
The utility model is further set to: described filter screen middle part is to upper process.
The utility model is further set to: described filter screen resistance welding is on drain valve.
By adopting technique scheme, the gas holder bottom of this oil-free air compressor has been fixedly connected with drain valve, again can emitting the ponding safety of gas holder inside by flexible pipe and spray gun, these ponding can also be used by spray gun simultaneously, can be used for cleaning, also can, for giving the cooling of the pump head on this oil-free air compressor, by the cyclic utilization of waste, save resource.
Accompanying drawing explanation
Fig. 1 is the utility model oil-free air compressor embodiment's structural representation;
Fig. 2 is the partial enlarged drawing of A in Fig. 1.
Reference character: 1, gas holder; 2, pump head; 3, breathing pipe; 4, castor; 5, drain valve; 6, filtrating equipment; 7, flexible pipe; 8, spray gun.
Embodiment
Referring to figs. 1 through Fig. 2, the utility model oil-free air compressor embodiment is described further.
A kind of oil-free air compressor, comprise gas holder 1 and pump head 2, described pump head 2 is arranged on gas holder 1, between gas holder 1 and pump head 2, be connected by breathing pipe 3, the below of described gas holder 1 is provided with castor 4, and described gas holder 1 bottom is fixedly connected with drain valve 5, described drain valve 5 and gas holder 1 internal communication, the water intake of described drain valve 5 is provided with filtrating equipment 6, and the water outlet of described drain valve 5 is connected with flexible pipe 7, and the other end of flexible pipe 7 is equipped with spray gun 8.Gas holder 1 bottom of this oil-free air compressor is provided with drain valve 5, again can emitting the ponding safety of gas holder 1 inside by flexible pipe 7 and spray gun 8, these ponding can also be used by spray gun 8 simultaneously, can be used for cleaning, also can be for lowering the temperature to the pump head 2 on this oil-free air compressor, by the cyclic utilization of waste, save resource.
Described filtrating equipment 6 is filter screen.Filter screen is made simple, and cost is low, and is convenient to install.
Described filter screen middle part is to upper process.Can prevent that foreign material from stopping up filter screen.
Described filter screen resistance welding is on drain valve 5.Filter screen and drain valve 5 are welded together, then drain valve 5 is welded on gas holder 1, easy to make, the material-structure of the more difficult destruction drain valve 5 of the relative electric welding of resistance welding and filter screen, has guaranteed working life of drain valve 5 and filter screen.
Claims (4)
