Description

It is convenient for changing the air filter of filter

Technical field

The utility model is related to a kind of air filter, the air filter of filter is particularly convenient for changing.

Background technology

Filter is mounted on inside by some existing air filters, since filter needs to regularly replace, during replacement It needs to split out filter and filter screen is cleaned again, operation is cumbersome；The air filtering excessively of some air filters simultaneously When measuring larger, caliber can be expanded to improve ventilation quantity, this so that the area of filter is also larger, damaged when occurring on filter When, in order to ensure filter effect, it is necessary to whole filter be replaced, maintenance cost is higher；Also there are some air filters Can use the smaller filter of multiple areas, but such air filter by entire larger filtering surface with brandreth be divided into it is multiple compared with Small filtering surface, then replaced on smaller filtering surface with the buckle smaller filter of mounting area, such air filter It is cumbersome during filter disc.Therefore there is replace the problem of filter is cumbersome and maintenance cost is higher for existing filter device.

Utility model content

The purpose of this utility model is that provide a kind of air filter for being convenient for changing filter.The utility model is not Filter can be only convenient for changing, also has the advantages that maintenance cost is relatively low.

The technical solution of the utility model：The air filter of filter is convenient for changing, including wind turbine, is connected on wind turbine Snorkel；One end on snorkel close to wind turbine is connected with electrostatic precipitator, and the other end is connected with filter device；Filtering dress It puts including square screen pipe, screen pipe is interior to be equipped with multiple slideways, and each slideway is in horizontally disposed；Multiple slideways are in vertical row Row, two neighboring slideway are connected with each other；The upper and lower ends of slideway are respectively connected with slide, the position that slideway both ends are connected with screen pipe Place is both provided with rubber strip；Multiple filters are provided in the slideway.

Foregoing is convenient for changing in the air filter of filter, and the width of the filter is equal in slideway two up and down The distance between slide, the sum of length of multiple filters is equal to the length of slideway in a slideway.

Foregoing is convenient for changing in the air filter of filter, the filter include upper ledge and lower frame, the one of upper ledge Side is hinged with lower frame；Filter screen is provided between upper ledge and lower frame, is set at the position that upper ledge bottom is overlapped with lower frame flexible Piece.

Compared with prior art, the utility model improves existing air filter, quiet by being connected on snorkel Electric precipitator carries out rough dusting, enhances filter effect；Square screen pipe is connected on snorkel, and equipped with more in screen pipe Slideway that is a horizontally disposed and being vertically arranged, and multiple filters are set in slideway, the larger filter screen of area is resolved into Multiple smaller filters of area so that when strainer damages, only need to change a fritter filter of filter screen damage, reduce Maintenance cost；Slide on slideway is set simultaneously, and anti-skidding work is provided at the position being connected in slideway with screen pipe side wall Rubber strip so that when replacing filter disc, only new filter need to be pushed into slideway, be from slideway taking-up by old filter Can, it is more convenient to replace filter.In addition, the filter of the utility model is divided into upper ledge and lower frame, and the one side of upper ledge and lower frame It is hinged, and filter screen is provided between upper ledge and lower frame so that upper ledge taking-up filter need to only be lifted by replacing filter screen, It is more convenient；During filter screen damage simultaneously, the filter screen inside filter is only needed to change, without replacing upper ledge and lower frame, into one Step reduces maintenance cost.Therefore, the utility model can not only be convenient for changing filter disc, also with maintenance cost it is relatively low and filtering Net replaces more conveniently advantage.

Specific embodiment

The utility model is further described with reference to the accompanying drawings and examples, but is not intended as to the utility model The foundation of limitation.

Embodiment.It is convenient for changing the air filter of filter, forms as shown in Figures 1 to 4, including wind turbine 1, on wind turbine 1 It is connected with snorkel 2；One end on snorkel 2 close to wind turbine 1 is connected with electrostatic precipitator 3, and the other end is connected with filtering Device 4；Filter device 4 includes square screen pipe 5, is equipped with multiple slideways 6 in screen pipe 5, each slideway 6 is set in level It puts；In being vertically arranged, two neighboring slideway 6 is connected with each other multiple slideways 6；The upper and lower ends of slideway 6 are respectively connected with slide 7, sliding Rubber strip 8 is both provided at the position that 6 both ends of road are connected with screen pipe 5；Multiple filters 9 are provided in the slideway 6.

The width of the filter 9 is equal to the distance between upper and lower two slides 7, multiple mistakes in a slideway 6 in slideway 6 The sum of length of filter disc 9 is equal to the length of slideway 6；The filter 9 includes upper ledge 10 and lower frame 11, and the one side of upper ledge 10 is under Frame 11 is hinged；Filter screen 12 is provided between upper ledge 10 and lower frame 11, is set at the position that 10 bottom of upper ledge is overlapped with lower frame 11 Flexible 13.

Operation principle：The upper ledge 10 of filter 9 is rotated around upper ledge 10 and the hinged one side of lower frame 11, make upper ledge 10 with Gap is vacated between lower frame 11, then filter screen 12 is placed on lower frame 11,12 surrounding of filter screen can be placed on 11 frame of lower frame Upper and filter screen 12 is without departing from the frame of lower frame 11；Then upper ledge 10 is rotated down, upper ledge 10 is overlapped simultaneously with lower frame 11 Filter screen 12 is pressed between upper ledge 10 and lower frame 11；It is set at the position overlapped due to 10 bottom of upper ledge with lower frame 11 flexible Piece 13 so that the clamping filter screen 12 that upper ledge 10 and lower frame 11 can be more stable, and filter screen 12 is pressed on lower frame 11 by upper ledge 10 When, flexible sheets 13 can be according to the thickness contraction of filter screen 12 so that upper ledge 10 can phase mutual respect after clamping filter screen 12 with lower frame 11 It closes.

The filter 9 for accompanying filter screen 12 is pushed into along slide 7 in slideway 6, during push-in, rubber strip 8 can be with filter 9 On frame generate frictional force so that filter 9 be pushed into relatively stablize.When having been filled with filter 9 in multiple slideways 6, start Wind turbine 1, wind turbine 1 introduce outdoor air in snorkel 2, when air passes through electrostatic precipitator 3, the partial impurities quilt in air It ionizes and adsorbs in electrostatic precipitator 3, then air passes through filter device 4 by snorkel 2；Air passes through filter device 4 When, air during filter screen 12 on filter 9 by that can be filtered.

When needing replacing filter 9, new filter 9 need to be only pushed into along 7 part of slide in slideway 6, new mistake Filter disc 9 squeezes out old filter 9 from the opposite side of slideway 6；Since rubber strip 8 can generate frictional force with 9 side of filter, make It obtains old filter 9 to be stuck between two slat gum items 8, then old filter 9 is taken out, then proceed to be pushed into new filter 9； It is operated before repeating afterwards, until old filter 9 all is replaced with new filter 9.Check the old filter 9 to swap out, There is damaged filter 9 to replace to filter screen 12, i.e. rotary upper 10, take out damaged filter screen 12 and change to new filtering Then net 12 reversely rotates upper ledge 10, upper ledge 10 is made to be overlapped with lower frame 11；Simultaneously by filter screen after inspection 12 without the old of damage Filter 9 carries out clean and maintenance so that old filter 9 can recycle.
