Description
Technical field
Airlock device is the utility model is related to, more particularly, to a kind of new airlock.
Background technology
Airlock is mainly used in material collection system, and as the discharger of feed bin, its operation principle is to work as top material
Due to being fallen under deadweight in the space between blade, drawn off with rotation to the lower section of blade, realize quantitative continuous blanking.It is existing
Airlock typically using cylinder control charging aperture and discharging opening opening and closing, generally require using at least two cylinder (charging apertures
One, discharging opening one), energy resource consumption is higher；Fit precision requires higher between multiple cylinders, material folding and putty easily occurs
Situation.
Utility model content
The purpose of this utility model is to be directed to above-mentioned present situation, there is provided a kind of new airlock.
The technical solution adopted in the utility model is：A kind of new airlock, including：One housing, a feed bin and a rubber
Bar, the feed bin are arranged on the enclosure interior, and the rubber strip is arranged on the housing；Divide above and below the housing
It is not provided with charging aperture and discharging opening, it is hollow in the housing, form cavity, the charging aperture and the discharging opening and the sky
Chamber connection conducting；The feed bin includes a cartridge case and a rotating shaft, and the cartridge case is provided with a feed bin opening, and the rotating shaft is set
Put at the center of cavity, the cartridge case is arranged in the rotating shaft, and can be made described in the drive lower swing of the rotating shaft
Feed bin opening moves back and forth between the charging aperture and the discharging opening.
Effect of the present utility model is：A kind of new airlock described in the utility model, by circular arc feed bin in shell
Rotation in body, the charging aperture on housing and discharging opening is set at a time to only have a unlatching, separately by being set on housing
Replaceable rubber strip with realize sealing, this programme is simple in construction, assembly precision require it is low, save the energy, be not easy material folding or
Putty, the probability of failure are small.
Brief description of the drawings
Fig. 1 show a kind of diagrammatic cross-section of new airlock provided by the utility model；
In figure：1-housing, 11-cavity, 12-charging aperture, 13-discharging opening, 2-feed bin, 21-cartridge case, 211-
Feed bin opening, 22-rotating shaft, 3-rubber strip.
Embodiment
New airlock provided by the utility model is introduced below in conjunction with the accompanying drawings：
Referring to Fig. 1, it is a kind of new airlock provided by the utility model, it includes：One housing 1, a feed bin 2 and one
Rubber strip 3, the feed bin 2 are arranged on inside housing 1, and the rubber strip 3 is arranged on housing 1.
Charging aperture 12 and discharging opening 13 are respectively arranged with above and below housing 1, section is provided with housing 1 as circular sky
Chamber 11, charging aperture 12 and discharging opening 13 are connected conducting, charging aperture 12 and discharging opening 13 and the circle of the junction of cavity 11 with cavity 11
Central angle corresponding to arc is more than 0 ° and less than 60 °.The section of charging aperture 12, the section of discharging opening 13 are on the section of cavity 11
The extended line of radius is symmetrical.
Further, in the present embodiment, feed bin 2 is arranged in the cavity 11 of housing 1, and feed bin 2 includes a cartridge case 21
With a rotating shaft 22.
Rotating shaft 22 is arranged on the center of cavity 11, and rotating shaft 22 is provided with support sealing structure with the contact position of housing 1.
Cartridge case 21 is arranged in rotating shaft 22, and can be in the drive lower swing of rotating shaft 22, and the section of cartridge case 21 is in circular arc
Shape, the central angle corresponding to the section of cartridge case 21 are more than 240 ° and less than 360 °.Cartridge case 21 is provided with a feed bin opening 211,
The section of feed bin opening 211 is in circular arc, and the section of feed bin opening 211 forms a circle with the section of cartridge case 21.
Further, in the present embodiment, several rubber strips 3 are arranged on housing 1, one end and material in housing 1
Storehouse shell 21 abuts.
When using new airlock, cartridge case 21 makes feed bin opening 211 in charging aperture in the drive lower swing of rotating shaft 22
Moved back and forth between 12 and discharging opening 13.When feed bin opening 211 moves to 12 underface of charging aperture, charging aperture 12 is led with feed bin 2
Logical, material is fallen into feed bin 2 by charging aperture 12, when feed bin opening 211 moves to 13 surface of discharging opening, discharging opening 13 with
Feed bin 2 is turned on, and material is dropped out by discharging opening 13.
A kind of new airlock described in the utility model, by the rotation of circular arc feed bin in the housing, makes on housing
Charging aperture and discharging opening at a time only have one unlatching, separately realized by setting replaceable rubber strip on housing
