Embodiment
An embodiment of the air compressor with safeguard function of the present utility model is shown in shown in Fig. 1-Fig. 5, this air compressor comprises casing 10, in casing, be mainly provided with motor, compression main frame and air-cooling device and air filter assembly 9, air-cooling device comprises blower fan 4, wind scooper 5 and radiator 6.
In the present embodiment, on a sidewall of casing housing 10, just the position of radiator is offered to exhaust port, self hang down type venetian blind 3 is installed on exhaust port, in the time that blower fan 4 starts work, the blade of this venetian blind is blown afloat outside swing by wind-force and opens, now venetian blind in opened condition, exhaust port can be normally outside air discharging and radiating; And in the time of blower fan stall, blade backswing under the effect of self gravitation resets, now venetian blind is closed condition, and exhaust port is covered up, and can prevent that dust rainwater etc. from entering radiator from exhaust port, so that radiator stops up and machine intimate accumulation of impurities.
As a part for an air-cooled cooling system, on other sidewalls of casing housing, also offer corresponding suction port, in order to prevent that rainwater from entering machine intimate from suction port, on suction port, be provided with rain-proof structure.The rain-proof structure that the present embodiment adopts is the venetian blind arranging on suction port, and the blade of venetian blind 2 is for being fixedly installed.In order to play dustproof effect simultaneously, on the inner side of this venetian blind, be also fixed with filtrating equipment, this filtrating equipment is that the screen pack 8 being oppositely arranged by two internal and external partitions and the sponge filter layer 7 being folded in the middle of two screen packs form; Because the filtrating equipment of this structure also can play rainproof effect, so can omit venetian blind on the suction port that this filtrating equipment is housed.
In the present embodiment, on the top board of air compressor casing, be fixed with fore filter 1, fore filter is positioned at the outside of top board, fore filter adopts the returning type air prefilter of air-out under lower air intake, the structure of returning type air prefilter has a variety of, the present embodiment adopts the air prefilter of structure shown in Fig. 5, the air outlet of this air prefilter is communicated with the suction port of the air filter assembly 9 of air compressor by air-flow path 20, and air-flow path is a seal case that is arranged on top board downside, air filter assembly top.When work, air draught is first by metal air inlet net 13, in air-flow, larger-size fragment is tackled by metal air inlet net, then when air draught is through static eddy flow groove 14, form the eddy current state of High Rotation Speed, under the promotion of the centrifugal force producing at eddy current cyclone, isolate the dust in air-flow, dirt, insect, the foreign material such as rainwater and snowflake, the rotor 15 of the High Rotation Speed being driven by eddy current cyclone is produced by boasting isolated foreign material from the dust discharge passage of air prefilter side, enter into air filter assembly 9 by air outlet 12 air-flow path 20 of flowing through through the clean air air-flow of preliminary purification, by air prefilter carry out after pretreatment can filtering air in 80% impurity.In Fig. 5, the 11st, anchor ear, for fixed air prefilter.
The air compressor of the present embodiment is particularly suitable for, as the rainwater such as harbour area and the serious occasion of dust pollution frequently, can reducing machine-spoiled rate, has greatly reduced the workload of operational maintenance machine.
The embodiment of the air compressor casing with safeguard function of the present utility model is identical with the casing structure of air compressor shown in above-mentioned Fig. 1-Fig. 5, no longer repeats herein.
