Abstract

The utility model relates to a device for preventing duster from secondary pollution, particularly a dust collector and other dust collecting facilities, which are used in daily lives. The utility model takes a container which is connected with a dust collector and contains water as the container of the device. One end of the container is provided with an intake path; a mesh screen used for preventing bubble from splashing is arranged in the container. The other end of the container is provided with an exhaust passage for clean air. The device can effectively overcome secondary pollution brought by dust produced from the tail of the dust collector in use.

Description

A kind of device that prevents the dust catcher secondary pollution

The utility model relates to dust catcher used in everyday, and other facility relevant with dust-absorbing filtering.

Usually be to have installed screen pack that dust bag and oily sponge class or certain reticular fibre material make additional to wait and realize filtered air in dust catcher inside at the dust catcher of selling on the market now, when gas was sucked by suction nozzle, dust had been stayed in the dust bag and has been deadened on filter screen.From use and in people's the reflection, people have formed certain common recognition: this kind dust catcher exists secondary pollution problem, and just total some dust can be raised in the air once more by steam vent.

In order to address this problem, be mostly to adopt the method that installs finer and closely woven screen pack additional.Such as a kind of dust catcher of producing by Holland design Japan, it forms filtration by four layers of screen pack, the hole of screen pack is very fine and closely woven, the nominal power of motor is 1000 watts, but also cannot say for sure not have fine dust under the strong suction effect overflows, and suction is under some influence, in addition fine and closely woven net is in case stopped up by tiny dust, and suction can be affected again naturally so.In addition, general domestic vacuum cleaners power is many to improve secondary pollution below 1000 watts as this practice by the net that installs fine and closely woven material additional, and obviously result of use will be affected.

In recent years, report a kind of more novel dust catcher abroad, solved secondary pollution problem, but be still the dust catcher of aforesaid kind now on the domestic market, even if new-type dust catcher listing, but original dust catcher is eliminated quickly, obviously be that economy is also real inadequately inadequately.

The purpose of this utility model is that a kind of device that solves dust catcher secondary pollution problem will be provided, it can prevent the tail gas that dust is arranged of discharging from the dust catcher afterbody pollution to room air effectively, and be not implemented in easily original dust catcher is done to realize this purpose under the situation of too big change.

The purpose of this utility model is to realize like this, make a casing or staving, its top one end has an air inlet and the corresponding combination of the exhaust outlet of dust catcher, there is a road that leads to bottom half to lead in import department, a bottom and a side in this passage lower end are provided with some exhausts, a certain amount of water is housed in casing, at some places below the water surface and be provided with that several sizes are suitable for body structure on the water surface and can carry out the mesh screen that is placed on water surface upper space and water inside, the other end of casing is provided with the exhaust passage.

The utility model is because of adopted tail gas that dust catcher is discharged mode of filtering by water thereby the degree that has significantly reduced secondary pollution, adopted mesh screen shape structure to eliminate more than the water surface and reduced seething and splash of bubble because of reaching under water again, and be provided with some apertures in the bottom and the side of passage lower end, also can alleviate the dynamics of seething of bubble, thereby guarantee to have reduced moisture content to the greatest extent difficultly from the giving vent to anger of outlet passageway of casing.Inlet channel and outlet passageway enough big, the pressure of giving vent to anger in order to minimizing, bubble splashed to be played a part to slow down.

The concrete structure of utility model is provided by following examples and accompanying drawing thereof.

Fig. 1 is the vertical view of this utility model, and Fig. 2 is the side cutaway view of Fig. 1, and Fig. 3 is the opposite side pseudosection of Fig. 1.

Below in conjunction with Fig. 1-3, describe the details and the working condition of the structure of the concrete device that the utility model proposes in detail.

It comprises a casing (1), be provided with an inlet channel (2) and air inlet (9) in the top, be provided with plurality of rows pore (4) on the bottom of the lower end (3) of inlet channel (2) and a side, steam vent (4) is towards the bottom of water (6) and a side of water (6).The bottom of the water surface (5) has together as for, and arterial highway mesh screen (7) is leaving some roads mesh screens (7) that the water surface (5) certain altitude is provided with the space, exhaust passage (8) is arranged at the other end on the top of casing (1), and casing (1) connects mutually with the tail end exhaust outlet of air inlet (9) and dust catcher.

When dust catcher is worked, the gas of holding dust under the arm via air inlet (9) to its lower end of inlet channel (2) (3) in and through steam vent (4) row in water (6), this moment, dust was trapped in the water, and the mesh screen (7) that turns on the bubble that gas generates to the water (6) has carried out screen one time, the intensity of seething of bubble begins to weaken, when on bubble continues, crossing flow surface (5), after some roads on its top mesh screens (7) filter once more, bubble belongs to elimination, and forms clean air in the no hydrospace of casing (1) and enter indoor via exhaust passage (8).

Claims

1, a kind of air filter, especially for the device that solves the dust catcher secondary pollution, this device has the casing or the staving (1) that connect mutually with dust catcher, one inlet channel (2) is arranged on casing (1), the exhaust outlet of passage (2) one ends and dust catcher links, the other end extends into casing (1) bottom, casing (1) other end is provided with an outlet passageway (8), it is characterized in that, the interior a certain amount of water (6) of can packing into of casing (1), the part of inlet channel (2) and lower end (3) are led to bottom half and are immersed in the water (6), are provided with mesh screen (7) more than the water surface (5) reaching the water surface (5) below.

2, device according to claim 1 is that cross section in the lower end (3) of the passage (2) that leads to casing (1) bottom is more than or equal to import (2), the bottom of (3) and a side are provided with plurality of rows pore (4) endways, the gross area of steam vent (4) greater than or near the area of the air inlet (9) of inlet channel (2).

3, device according to claim 1 is provided with several mesh screens at casing (1) and below the water surface (5) and more than the water surface (5), can select different densities and some roads mesh screens (7) according to the suction size of dust catcher.
