Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1-5, the two-way dehumidification type sealed fume hood disclosed by the utility model comprises a first cabinet body 1, wherein a filtering device 2 is fixedly installed on the right side of the first cabinet body 1, and a second cabinet body 3 is fixedly installed on the right side of the filtering device 2.

In fig. 3, the first fan 201 is used for conveying the gas containing the toxic and harmful substances to the filter box 203 through the connecting pipe 202, the diatom ooze board, the glass fiber board, the activated carbon board and the mineral substrate in the filter box 203 adsorb and filter the toxic and harmful substances, and the filtered clean air is conveyed to the outside through the ventilation pipe 205 under the action of the second fan 206, so that the toxic and harmful substances can be effectively prevented from affecting the environment.

In fig. 3, when the left and right first fans 201 extract the gas containing toxic and harmful substances inside the fume hood, the first filter plate can prevent the garbage with large volume from entering the inside of the first fan 201, so as to prevent the first fan 201 and the connecting pipe 202 from being blocked, and the collecting cover can prevent the toxic and harmful gas from leaking in the process of entering the filter box 203 through the connecting pipe 202.

In fig. 3, the first cabinet body 1 and the second cabinet body 3 are both fixedly connected with the filter box 203 through the first fan 201 and the connecting pipe 202, so that the filter box 203 can simultaneously filter the gas containing toxic and harmful substances generated inside the first cabinet body 1 and the second cabinet body 3, and the filter device 2 does not need to be additionally arranged for each fume hood, thereby greatly reducing the production cost of the fume hood.

In fig. 1 and 4, after the air generated inside the fume hood is filtered for a long time by the filter box 203, the illuminating lamp inside the filter box 203 is turned on, so that the using conditions of the diatom ooze plate, the glass fiber plate, the activated carbon plate and the mineral substrate can be observed through the glass observation window on the front surface of the box door, and therefore the filter box 203 can be cleaned, replaced and maintained timely, and the filtering effect of toxic and harmful substances is guaranteed.

In fig. 3, when the gas generated inside the fume hood is conveyed to the inside of the filter box 203, firstly the diatom ooze plate can adsorb large particles in the gas, then the glass fiber plate can adsorb micro particles in the gas, then the activated carbon plate can carry out the first further adsorption and filtration on toxic and harmful substances in the gas, and finally the mineral substrate can further adsorb, degrade and filter the toxic and harmful substances in the gas.

In fig. 3, a top plate is fixedly installed between the first cabinet 1 and the second cabinet 3, the top plate is close to the tops of the first cabinet 1 and the second cabinet 3, the bottom of the ventilation pipe 205 penetrates through the top of the filter box 203 and extends to the inside of the filter box 203, the top of the ventilation pipe 205 penetrates through the bottom of the top plate and extends to the outside of the top plate, and the second fan 206 is close to the bottom of the ventilation pipe 205.

The technical scheme of the embodiment is as follows: through setting up filter box 203, when the inside of fume hood produced a large amount of poisonous and harmful substance, under the effect of first fan 201, poisonous and harmful substance can get into filter box 203 through connecting pipe 202 in, the inside diatom mud board of filter box 203, the glass fiber board, activated carbon board and mineral base plate filter poisonous and harmful substance, wherein the diatom mud board adsorbs the great granule of volume in to poisonous and harmful substance, the glass fiber board adsorbs the microparticle in the poisonous and harmful substance, the activated carbon board carries out preliminary absorption to poisonous and harmful substance, the mineral base plate is when further adsorbing poisonous and harmful substance, can also degrade some harmful and harmful substance, after poisonous and harmful substance is adsorbed, clean air can be discharged to the external world promptly, can not cause the influence to the environment.

Moreover, by arranging the filter box 203, most of the filter structures of the existing fume hoods are positioned at the top or the back of the fume hood, the filter structures are relatively fixed and are not convenient to replace, clean and maintain, the diatom ooze plate, the glass fiber plate, the activated carbon plate and the mineral substrate inside the filter box 203 are all inserted into the inner wall of the filter box through the insertion blocks, so that when the diatom ooze plate, the glass fiber plate, the activated carbon plate and the mineral substrate are replaced, cleaned and maintained, only the box door needs to be opened and the diatom ooze plate, the glass fiber plate, the activated carbon plate and the mineral substrate need to be drawn out, and the diatom ooze plate, the glass fiber plate, the activated carbon plate and the mineral substrate need to be replaced, cleaned and maintained, when the replacement, cleaning and maintenance are completed, the diatom ooze plate, the glass fiber plate, the activated carbon plate and the mineral substrate are inserted into the inner wall of the filter box 203 through the insertion blocks again, and the filter box 203 can filter toxic and harmful substances again, the whole maintenance process is simple and quick, and the filtering performance of the filter box 203 is ensured.

The implementation principle of the embodiment is as follows: when using the fume hood, open the switch of first fan 201 and second fan 206 earlier, then under the effect of first fan 201, gaseous through connecting pipe 202 get into in the rose box 203, the diatom mud board in the rose box 203, the glass fiber board, activated carbon board and mineral substrate carry out adsorption filtration to poisonous harmful substance, after poisonous harmful substance in the gas is filtered, under the effect of second fan 206, clean gas is discharged through ventilation pipe 205, gaseous can not lead to the fact the influence to the environment yet, the fume hood is carrying out big piece spraying paint, when powder bagging-off and chemical experiment, can produce a large amount of poisonous harmful substance usually, the air filtration purification structure of current fume hood can not be fine filters poisonous harmful substance, still can have poisonous harmful substance to be discharged to the external world, the problem of influence is led to the fact to the environment.

The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered by the protection scope of the utility model.
