Background technique
In machine industry, vacuum pump refers to and utilizes machinery, physics, chemistry or physicochemical method to be bled and the device or the equipment that obtain vacuum to taking out container, is widely used in the fields such as pigment chemical industry, tile machinery, Cryo Equipment, papermaking equipment, medication chemistry, food machinery, industrial furnace, electron trade, vacuum equipment, chemical fertilizer, metallurgy, oil, mine, basement process.According to the working principle of vacuum pump, vacuum pump can be divided into two types substantially, i.e. gas transport pump and gas capture pump.Vacuum pump in use, there will be the adverse conditions such as key position wearing and tearing such as overheated, rotor, affect working life and the use safety of vacuum pump, there is overheated situation mainly because heat radiation is not all rapidly even, the heat shed is greatly not as good as heat production, occur that the situation of wearing and tearing is then that impurity causes injury to key position because air intake is with impurity.
Summary of the invention
The invention provides a kind of vacuum pump, can effectively dispel the heat, avoid sucking impurity, reduce noise, in order to solve technique scheme, the present invention adopts following technological scheme:
A kind of vacuum pump, comprise housing, described housing side is provided with output shaft, described housing upper end is provided with intake grill and exhaust outlet, be provided with air inlet filtering device between described intake grill and housing, between described exhaust outlet and housing, be provided with air-out filtrating equipment, described housing is provided with refrigerator, described refrigerator is connected with intake grill, and described housing both sides are provided with radiating fin; Described housing the same side is provided with two symmetrical decks, and described deck is fixedly connected on housing, there is draw-in groove between described deck and housing, and described radiating fin both sides are provided with fixture block, and described fixture block matches with draw-in groove.
The invention provides a kind of vacuum pump, preferably, described air-out filtrating equipment and air inlet filtering device include active carbon layer, layer of fibers and nonwoven layer.
The invention provides a kind of vacuum pump, preferably, described fixture block is strip, and described fixture block is provided with non-slipping block on the surface, and described non-slipping block is connected for detachable with between fixture block.
Advantage of the present invention and beneficial effect are:
Vacuum pump provided by the invention, compact structure, housing is provided with filtrating equipment, silencer, refrigerator and radiating fin, in air inlet, air inlet filtering device is set, can greatly reduce the impurity entering pump body, the protection pump housing is not frayed, increases the service life; Housing arranges silencer, and silencer is connected with exhaust outlet, effectively eliminates the wind noise that exhaust outlet place produces; Housing arranges refrigerator, and refrigerator is connected with intake grill, directly cools air intake, makes cooling air carry out further circulating cooling to pump body; Housing both sides are provided with radiating fin, further the heat production of the pump housing are dispersed, keep the running temperature of vacuum pump, prevent it overheated.
Vacuum pump provided by the invention, housing sets up deck, and arrange fixture block on a heat sink, fixture block matches with this deck, is fixed on by radiating fin on housing simultaneously, for convenience detach and maintenance.
Vacuum pump provided by the invention, the fixture block of radiating fin arranges non-slipping block, frictional force between further increase radiating fin and deck, better fixing, non-slipping block is detachable simultaneously, when wearing and tearing being produced to non-slipping block when pulling and pushing repeatedly, can non-slipping block be changed, there will not be loosening situation.
Accompanying drawing explanation
Carry out describing in detail or preferably to the preferred embodiment of the present invention below in conjunction with accompanying drawing.
Fig. 1 is the schematic diagram of a kind of vacuum pump of the present invention.
Fig. 2 is the schematic diagram of radiating fin in a kind of vacuum pump of the present invention.
Fig. 3 is the schematic diagram of deck place part in a kind of vacuum pump of the present invention.
Embodiment
With reference to accompanying drawing 1-3, the invention provides a kind of vacuum pump, comprise housing 1, described housing 1 side is provided with output shaft 2, described housing 1 upper end is provided with intake grill 4 and exhaust outlet 5, air inlet filtering device 7 is provided with between described intake grill 4 and housing 1, air-out filtrating equipment 9 is provided with between described exhaust outlet 5 and housing 1, described housing 1 is provided with refrigerator 6, described refrigerator 6 is connected with intake grill 4, primary filter 8 is also provided with in the initial end of intake grill 4, this primary filter 8 comprises multiple layer metal filter screen, described housing 1 both sides are provided with radiating fin 3, described housing 1 the same side is provided with two symmetrical decks 11, described deck 11 is fixedly connected on housing 1, draw-in groove 12 is there is between described deck 11 and housing 1, described radiating fin 3 both sides are provided with fixture block 13, described fixture block 13 matches with draw-in groove 12, and air-out filtrating equipment 9 and air inlet filtering device 7 include active carbon layer 11, layer of fibers 12 and nonwoven layer 13.
Especially, described fixture block 13 is in strip, described fixture block 13 is provided with non-slipping block 14 on the surface, described non-slipping block 14 is connected for detachable with between fixture block 13, the face that fixture block 13 is adjacent and vertical with radiating fin 3 is provided with the equally distributed groove of row, this groove can insert for non-slipping block 14, when non-slipping block 14 damages, can change it fast.
Air-out filtrating equipment 9 and air inlet filtering device 7 are provided with three-decker, effectively can go out impurity in air and harmful matter, nonwoven layer 13 is arranged on topmost, particulate matter that can be effectively larger in filtered air, filtering effect is better, then be layer of fibers 12, when particulate in air is by layer of fibers, be deposited in fiber layer surface, further to less, the material that nonwovens cannot carry out filtering simultaneously filters, last active carbon layer 11 has larger adsorption area, the harmful gas molecule in the air after twice filtration can be adsorbed, the safety of available protecting environment and equipment.
Refrigerator 6 is directly connected with intake grill 4, and it is arranged between air inlet filtering device 7 and housing 1, when opening vacuum pump, directly carrying out cooling down to the gas through filtering, making it enter pump body circulating cooling, taking away the heat of pump body.
The fixture block 13 of radiating fin 3 arranges non-slipping block 14, increases the frictional force between radiating fin 3 and deck 11 further, better fix, non-slipping block 14 is detachable simultaneously, when carrying out keeping in repair or checking, needing radiating fin 3 to extract from deck 11, inserting again after maintenance is good, so repeatedly, inevitable wearing and tearing can be caused to non-slipping block 14, produce situation about loosening, now only need change non-slipping block 14, need not change whole deck 11 or fixture block 13, greatly save cost.
Above-described is only the preferred embodiment of the present invention.It should be pointed out that for the person of ordinary skill of the art, under the premise without departing from the principles of the invention, can also make some distortion and improvement, these also should be considered as belonging to protection scope of the present invention.
