Granular filter material filling device
Technical field
The utility model relates to granular filter material filling device.
Background technology
In air purifier, the normal impurity used in various media filtration or absorbed air, as activated carbon granule.General, granular filter material is placed in and possesses in the filter of grid, in each grid of filter, be full of granular filter material granular filter material, and at the both sides port capping screen pack of grid, to stop that granular filter material overflows.When outer gas stream is worn to filter opposite side by the side of filter, the impurity in air-flow will be adsorbed by granular filter material in real time.
But because granular filter material is filled in grid, air through grid granular filter material, produces and beats thus produce noise under wind action; And, due to granular filter material when beating between particle phase mutual friction produce dust, cause dust pollution; In addition, traditional filter screen is inlet end and outlet side is encapsulation, and therefore, when losing efficacy of filtrating box, need integral replacing, use cost is higher.
Utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide granular filter material filling device, can reduce the cost changing granular filter material.
The purpose of this utility model realizes by the following technical solutions:
Granular filter material filling device, comprise filter and screen pack, filter is arranged in length and breadth by multiple grid and is formed by connecting, the bottom of grid is provided with the containing portion for splendid attire granular filter material, above containing portion, grid top is set to the air channel passed for air-flow, the one end, air channel being positioned at filter front is air flow inlet and the one end, air channel being positioned at the filter back side is air stream outlet, air flow inlet is for dropping into granular filter material and being communicated with air stream outlet, and this air flow inlet is higher than containing portion, screen pack is fixed on the filter back side and all air stream outlets of capping and all containing portion.
Preferably, containing portion and air stream outlet are just right.
Preferably, grid is the body that uiform section extends, and the bearing of trend of this body favours filter.
Preferably, the cross section of body is hexagon, and filter is the cellular board that the arrangement of each grid is formed.
Preferably, screen pack is the dictyosome with cellular mesh.
Compared to existing technology, the beneficial effects of the utility model are:
The air flow inlet that the utility model passes through to arrange within a grid is higher than containing portion, and be communicated with air stream outlet, therefore, after air-flow penetrates grid from filter front, granular filter material will be formed to component straight down, compressing granular filter material is close to containing portion, granular filter material is avoided to beat, energy noise decrease, avoid the dust occurring causing because beating, and the air after energy consumption output filtering that can be lower, and, screen pack is only covered in the filter back side, therefore granular filter material can add toward containing portion at air flow inlet place or change, greatly facilitate to change and safeguard and use, and the cost changing granular filter material or maintenance is lower.

Detailed description of the invention
Below, by reference to the accompanying drawings and detailed description of the invention, the utility model is described further:
Granular filter material filling device as shown in figures 1-4, comprise filter and screen pack, filter is arranged in length and breadth by multiple grid and is formed by connecting, the bottom of grid is provided with the containing portion for splendid attire granular filter material, above containing portion, grid top is set to the air channel passed for air-flow, the one end, air channel being positioned at filter front is air flow inlet and the one end, air channel being positioned at the filter back side is air stream outlet, air flow inlet is for dropping into granular filter material and being communicated with air stream outlet, and this air flow inlet is higher than containing portion, screen pack is fixed on the filter back side and all air stream outlets of capping and all containing portion.
Cross the air flow inlet that arranges within a grid higher than containing portion, and be communicated with air stream outlet, therefore, after air-flow penetrates grid from filter front, granular filter material will be formed to component straight down, compressing granular filter material is close to containing portion, granular filter material is avoided to beat, energy noise decrease, avoid the dust occurring causing because beating, thus the air after energy consumption output filtering that can be lower, and, screen pack is only covered in the filter back side, therefore granular filter material can add toward containing portion at air flow inlet place or change, greatly facilitate to change and safeguard and use, and the cost changing granular filter material or maintenance is lower.Granular filter material can be the filtering material such as activated carbon granule, formaldehyde absorbing particle.
Particularly, after air-flow comes in and goes out grid from filter front, air-flow enters air channel through air flow inlet, and the impurity in air is adsorbed by containing portion endoparticle shape filtrate, and air flows out through air stream outlet simultaneously.Wherein, because air flow inlet is higher than containing portion, screen pack is covered in air stream outlet, and therefore granular filter material can not be deviate from from air flow inlet, also will be subject to the restriction of screen pack, thus is stablized spacing in containing portion.
Granular filter material is contacted more fully for making air-flow, to strengthen air filtration effect, containing portion and air stream outlet are just right, after then air-flow enters air channel, by the granular filter material fully contacted in containing portion, exported by air stream outlet again, and air-flow to the thrust that granular filter material is formed will be filtered net stop spacing, prevent granular filter material from deviating from grid.
As one preferred embodiment, the grid of this example is the body that uiform section extends, and the bearing of trend of this body favours filter.The uiform section of body arranges and is further beneficial to that air-flow is accessible to be passed through, and the inclination of its axis, the containing portion of being told somebody what one's real intentions are autonomous in-position after also making containing portion insert grid, facilitates interpolation and the replacing of granular filter material.
For to air draught formed evenly filtration, purification effect, the cross section of body be hexagon, filter be each grid arrangement formation cellular board.
For fitting tightly grid better, to prevent granular filter material particulate from spilling, screen pack is the dictyosome with cellular mesh.
To one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection domain of the utility model claim.
