Abstract
The utility model discloses an internal sucking and external pressing smoke gas collector comprising a shell. An inner core is arranged in the middle of the shell. An outer chamber is formed by the shell and the inner core. The inner core contains an internal chamber, which connects the withdrawal type blower through the air suction pipeline. The outer chamber is connected to the press type blower via the exhaust pipeline. The utility model can increase the suction lift of smoke gas. Meanwhile, cone-shaped air wall can be formed to improve the effect of collection and reduce the absorption of harmless air.
Description
Technical field
The utility model relates to a kind of novel smoke and dust collecting device, is a kind of internal sucking and external pressing smoke and dust collecting device.
Background technology
At present, for pernicious gas in work or the life or dust etc., generally be to adopt smoke and dust collecting device, smoke and dust collecting device commonly used is generally simple suction-type or simple discharge formula structure.Simple discharge formula flue dust smoke and dust collecting device just sprays simply, dilution function, can not remove pernicious gas or dust well.Simple suction-type smoke and dust collecting device can absorb a part of pernicious gas or dust, but on the one hand owing to inhale the journey weak point, has influenced assimilation effect; On the other hand, also sucking simultaneously has innocuous gas etc., causes negative effect.
The utility model content
The purpose of this utility model just is to provide a kind of collection flue dust better effects if to pernicious gas or dust etc., simultaneously, can also increase the internal sucking and external pressing smoke and dust collecting device of inhaling journey.
The purpose of this utility model can realize by following measure:
The utility model comprises urceolus, is provided with inner core in the middle of urceolus, forms exocoel between urceolus and the inner core, is inner chamber in the middle of the inner core, and inner chamber links by exhaust pipe and pull-out type blower fan, and exocoel links by gas exhaust piping and forced blower fan.
When the utility model is used for the fully-mechanized digging machine dedusting, fully-mechanized digging machine cutting units rocking arm drill bit should be set in inner chamber.Fully-mechanized digging machine cutting units rocking arm promptly is set in inner chamber, and cutting units rocking arm front is the fully-mechanized digging machine drill bit.Certainly, also can cooperate other suitable device to unite use, as smoke exhaust ventilator etc.The open end of urceolus and inner core all is connected with horn mouth.Horn mouth be in circle, square, rectangle, the polygon any, also can be other suitable shapes, the horn mouth that inner/outer tube connects.Its inside and outside iiared port shape should adapt with the local physical dimension that produces flue dust.Be provided with pillar between urceolus and the inner core,, thereby form exocoel in order to the support inner/outer tube.
The utility model promptly is provided with urceolus and inner core owing to adopt said structure, and forms inside and outside two-layer cavity, and joins with corresponding pull-out type blower fan and forced blower fan respectively at inner chamber, exocoel.Thereby in use can increase the suction journey of flue dust greatly; Simultaneously, also by the collaborative gas wall that forms taper in the air port in inside and outside chamber, improved the effect of collection flue dust.And reduced absorption to innocuous gas, and reduced the loss of machine energy, saved operating cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the utility model when being used for the fully-mechanized digging machine dedusting, the structural representation when being provided with fully-mechanized digging machine cutting units rocking arm drill bit in inner chamber;
Distinguished and admirable flow field figure when Fig. 3 is the utility model work.
The specific embodiment
The utility model is done with detailed description below in conjunction with drawings and Examples:
As shown in the figure, the utility model comprises urceolus 9, in the middle of urceolus, be provided with inner core 10, be provided with pillar 8 between urceolus and the inner core, form exocoel 1 between urceolus and the inner core, in the middle of the inner core 10 is inner chamber 2, and inner chamber 2 links by exhaust pipe 4 and pull-out type blower fan, and exocoel 1 links by gas exhaust piping 3 and forced blower fan.When the utility model is used for the fully-mechanized digging machine dedusting, fully-mechanized digging machine cutting units rocking arm drill bit should be set in inner chamber.Fully-mechanized digging machine cutting units rocking arm promptly is set in inner chamber 2, and cutting units rocking arm front is a fully-mechanized digging machine drill bit 7.Certainly, also can cooperate other suitable device to unite use, as industry such as smoke exhaust ventilator, collection flue dust device in civilian.The open end of urceolus 9 and inner core 10 all is connected with horn mouth.The outer horn mouth 5 of outer socket joint, interior socket joint inside trumpet mouth 6.Each horn mouth be in circle, square, rectangle, the polygon any.This horn mouth also can be other suitable shapes.For the inside and outside horn mouth that inner/outer tube connects, its inside and outside iiared port shape should adapt with the local physical dimension that produces flue dust.
Operation principle of the present utility model is as follows:
The purpose of this utility model is that the air velocity distribution of exocoel in utilizing concentrates on concentrated again removing in the minimum scope with poisonous and hazardous article such as flue dust gas etc.Its inner chamber 2 dress pull-out type blower fan manage-styles, exocoel 1 are adorned forced blower fan airduct, but the suction stream of exocoel jet and inner chamber can be enclosed in respirable dust in the scope of inner chamber like this, focuses on deduster again.Distinguished and admirable flow field figure during work is seen figure 3, but because respirable dust moves with distinguished and admirable flow field.Just dust is concentrated on the fully-mechanized digging machine cutting units in the work like this, reduced the dust pollution scope.Also have it to utilize the range of jet flow field to flow the long principle in flow field than inhaling, the principle of the two comprehensive function carries out inhaling in the external pressure control dust.
