Description

Air cleaner

Technical field

The utility model relates to a kind of air cleaner of handling air, can remove airborne dust particle, penetrating odor and part toxic gas etc.

Background technology

In some Medical Devices and welding job, because need of work often produces some metal oxide gas, the irritative gas that the protein burning produces, have a strong impact on operating personnel's operate as normal and endanger the healthy of staff, before this utility model air cleaner comes out, produced pollution gas is handled by 3 kinds of methods when this class Medical Devices operation and welding: 1) when erection unit, after equipment is in place, it is in line in atmosphere to add exhaust hood above the generation dusty gas, the drawback that exists: because exhaust hood is in the pollution sources top, near and the roof, so dusty gas stream is through operating personnel's respiratory region; Because dusty gas stream is not closed system, so system is affected by the external environment easily, it is indoor to cause dusty gas to be diffused into; Dusty gas directly is discharged in the atmosphere without purifying, and pollutes the surrounding air quality; Noise is big; Mounting condition is limited etc.2) adopt activated charcoal strainer, have drawback: filter area is little; Life-span is short, and the replacement cycle is too frequent, can not effectively utilize resource.3) adopt the normal air clearing machine, have drawback: sealing effectiveness is not ideal enough; Clearing machine internal filter mounting means is reasonable inadequately; The filter fixed form is loaded down with trivial details, when maintenance and replacing cumbersome (filter weight is big, and the equipment operator mostly is the woman greatly).Based on above reason, existing market is badly in need of a kind of air cleaner novel, hommization and is created brand-new working environment and pure and fresh air for the mankind.

Summary of the invention

The purpose of this utility model provides a kind of air cleaner novel, hommization, it is the device to the contaminated air purified treatment, can be used in the Medical Devices of hospital's generation dusty gas, on welding post, use separately, also can use the place of concentrating, reach and handle the purpose that dusty gas is created fresh air with other air pollution sources.

For achieving the above object, the utility model adopts following design: a kind of air cleaner, comprise and to tune flexible air-breathing arm, purify casing, purify casing again by the filter access door, the filter supporting plate, slide rail, composite type filter, the sealing knife rest, critical pieces such as blower fan are formed, purify the interior blower fan of casing from flange air inlet suck pollution gas, after the dusty gas process composite type filter purified treatment, become pure air, indoor through being discharged to from air draft blinds hole behind the blower fan, it is characterized in that: described composite type filter places on the filter supporting plate that is fixed on the slide rail; The sealing knife rest is positioned at composite type filter rear end and blower fan front end in the air cleaner; Described the be tightly connected annular outlet structure of mode and flange air inlet of flexible air-breathing arm and flange air inlet employing plug-in type that tunes.It is characterized in that: as shown in Figure 1, when maintenance and replacing composite type filter, only need open the filter access door, unclamp the filter hold down gag, level is pulled out the filter supporting plate, it is external that composite type filter also skids off purifying box thereupon, change failed composite type filter with new composite type filter, put after the composite type filter according to the keeper on the filter supporting plate, level pushes the filter supporting plate, when shifting onto can not advance the time, composite type filter puts in place, with the locked composite type filter of filter hold down gag, close the filter access door, composite type filter is changed and is finished; As shown in Figure 2, the sealing means of the air cleaner of design, the sealing effectiveness of assurance whole system, level promotes the filter supporting plate, and composite type filter is by the frictional force f of gravity generation own and the thrust F of the generation of the reference column on the filter supporting plate ₁Make composite type filter do horizontal movement with the filter supporting plate, when the sealing strip on the composite type filter air-out end face touched the sealing knife rest that purifies in the casing, because the sealing strip material has elasticity, and the elastic force that produces was not enough to overcome F ₁And f, so composite type filter along with the filter supporting plate continues to be subjected to displacement forward, when moving to a certain degree, sealing strip can't compress, and the resistance that is brought by the sealing knife rest has overcome F ₁And f, the filter supporting plate can't move forward, at this moment composite type filter puts in place, and apply the power of 4 identical equal and opposite in directions of direction perpendicular to the composite type filter end face this moment respectively on the close position at four angles of composite type filter frame, locked composite type filter.Because the area of section of sealing knife rest is little, pressure is big, can guarantee that the sealing strip and the contact-making surface of sealing knife rest seal fully, and has reduced the resistance of system by the static pressure space that forms of sealing knife rest, has improved the service efficiency of composite type filter.As shown in Figure 3, can tune flexible air-breathing arm and flange air inlet adopts plug-in type to be tightly connected, form a circular socket by pipe in flange air inlet outer tube and the flange air inlet, in socket, add fluid sealant, insert the flange air inlet tuning flexible air-breathing arm then, after fluid sealant solidifies, can tune firm being fixed on of flexible air-breathing arm and purify on the casing.As shown in Figure 4, the filter hold down gag adopts spring assembly, spring one end is fixed on the casing, the other end is fixed on the F shape compressing structure, after composite type filter puts in place, pull out F shape fixture (F shape front end quarter butt is handle), when moving correct position to, rotation F shape compressing structure makes its depression bar be in horizontal direction, and be pressed onto on the composite type filter frame, it is identical to have applied 4 sizes in the position near 4 angles of composite type filter frame thus, and the elastic force that direction is identical guarantees the sealing that composite type filter is installed; When getting composite type filter, stretching filter hold down gag, 90 ° of rotation F shape fixtures make spring reset then, and composite type filter can take out.

The utility model has the advantages that: air cleaner has graceful profile; Unique sealing means has excellent sealing effectiveness; Composite type filter adopts the mounting means of drawing and pulling type, and simple filtering device fixed form is convenient for changing filter, and having solved the normal air clearing machine is needing blue-collar operation with changing filter; The composite type filter long service life; Can tune convenient connection of flexible air intake duct and adjustment, operating noise is little; It is extensive that use reaches the scope of application flexibly.
