Abstract
The utility model discloses a negative pressure dust collection structure, its characterized in that, it includes the casing and sets up at its surperficial tuber pipe, just tuber pipe and the inside intercommunication of casing, the casing is thin wall cavity, and two is the loudspeaker form, and inside is provided with the inner tube, the inner wall of wide -mouth is connected hermetcally on inner tube upper end and the casing, and the lower extreme is unsettled. The utility model aims at providing a negative pressure dust collection structure makes the dust catcher use like ordinary dust catcher, and the while can not make by inspiratory gas or medium entering pump body impeller in being applicable to industrial environment yet to the harm is avoided causing by the parts of protection dust catcher, and increase of service life improves the security performance.
Description
Technical field
This utility model belongs to Environmental-protecting dust-removing field, specially a kind of the aspiration of negative pressure structure.
Background technology
In manufacture process, particularly spinning, weaving and wool spinning workshop, the batting dust in workshop is more, for
The health of operator has considerable influence；And batting arbitrarily floating in atmosphere, is easy to cause the things such as fire safety evaluating in a large number
Therefore.Therefore no matter for the angle of protection labourer or maintenance shop safety in production, all should actively remove in workshop
Batting dust.
More than the existing device except batting dust in the form of negative-pressure air fan, and in order to ensure that air inlet can be effective
Ground carries out negative-pressure adsorption to batting dust, employs larger aerator, wind speed is larger, and air velocity is larger more, and one
As all carry higher temperature（The temperature of workshop batting dust）.The pump housing of existing negative-pressure air fan is typically disposed in vacuum cleaner tail end
Or in main body, anyway, in the aspiration of negative pressure, the gas that is inhaled into all can be and long playing through pump housing impeller,
So that some batting dust can be accumulated in the pump housing, make the parts such as impeller, bearing stuck, accelerated wear test；Height when simultaneously running
Temperature is also easily that batting dust produces spontaneous combustion.
Utility model content
This utility model purpose is to provide a kind of the aspiration of negative pressure structure, so that vacuum cleaner is used as standard vacuum,
Also can be suitably used in industrial environment simultaneously, the gas being inhaled into or medium will not being made to enter pump housing impeller, thus protecting dust suction
The parts of device, it is to avoid cause damage, increase the service life, and improve security performance.
For realizing object above, the technical solution adopted in the utility model is：A kind of the aspiration of negative pressure structure, it includes housing
（1）With the airduct being arranged on its surface（4）, and described airduct（4）With housing（1）Internal connection；Described housing (1) is in thin-walled
Sky, two is horn-like, is internally provided with inner tube（2）, said inner tube（2）Upper end and housing（1）The inner wall sealing of upper end wide-mouth
Ground connects, and lower end is hanging.
Further, said inner tube（2）Upper end is horn-like, said inner tube（2）Lower end is to housing（1）Lower end extends, and
Exceed airduct（4）With housing（1）Interface, and tail end be funnel-form.
Further, described housing（1）Upper end is flange face, and is provided with seam（12）, lower end is provided with screw thread（13）.
Further, described airduct（4）With housing（1）The connection tilting.
The beneficial effects of the utility model：
1. structure is simple, practical, can effective protection internal body parts；
2. it is applied to many dust works workshop, particularly spinning, weaving and wool spinning workshop；
3. easy accessibility is it is easy to clear up；
4. prevent batting dust from can accumulate in the pump housing and produce spontaneous combustion, improve security performance.
Brief description
Fig. 1 is this utility model perspective view.
Fig. 2 is this utility model main cross-sectional schematic diagram.
Described in figure, label character is expressed as：1st, shell；2nd, inner tube；3rd, interlayer；4th, airduct；11st, flange hole；12nd, seam；
13rd, screw thread.
Specific embodiment
In order that those skilled in the art more fully understand the technical solution of the utility model, below in conjunction with the accompanying drawings to this reality
It is described in detail with new, the description of this part is only exemplary and explanatory, should not be to protection domain of the present utility model
There is any restriction effect.
As Figure 1-Figure 2, concrete structure of the present utility model is：Including housing 1 and the airduct 4 being arranged on its surface,
And described airduct 4 is internal with housing 1 connects；Described housing 1 is thin wall hollow, and two is horn-like, is internally provided with inner tube 2,
Said inner tube 2 upper end is connected with the inner wall sealing ground of housing 1 upper end wide-mouth, and lower end is hanging.
Preferably, said inner tube 2 upper end is horn-like, expands intake, said inner tube（2）Lower end is to housing（1）Lower end
Extend, and exceed airduct（4）With housing（1）Interface, prevent back flow of gas, and tail end be funnel-form, make gas flow rate faster,
Produce higher negative pressure.
Preferably, described housing 1 upper end is flange face, and is provided with seam 12, and lower end is provided with screw thread 13, has good
Sealing with, and threaded easy disassembly cleaning.
Preferably, the described airduct 4 being arranged on housing 1 surface forms inclination angle with horizontal plane, makes airduct 1 with housing (1) more
Easily form gaseous exchange.
When specifically used, inside the aspiration of negative pressure device, flange hole 11 and fan outlet phase are passed through in the upper end of shell 1
Even, the wind of high flow rate flows through so that forming negative pressure in interlayer 3 inside inner tube 2, and airduct 4 is communicated with interlayer 3, forms negative pressure
Suction port；Shell 1 lower end is connected with tail gas handss collection device by screw thread 13, collects the waste material of tail gas and suction.
It should be noted that herein, term " inclusion ", "comprising" or its any other variant are intended to non-row
The comprising of his property, so that including a series of process of key elements, method, article or equipment not only include those key elements, and
And also include other key elements of being not expressly set out, or also include intrinsic for this process, method, article or equipment institute
Key element.
Specific case used herein is set forth to principle of the present utility model and embodiment, above example
Illustrate to be only intended to help understand method of the present utility model and its core concept.The above is only of the present utility model preferred
Embodiment is it is noted that due to the finiteness of literal expression, and objectively there is unlimited concrete structure, for this technology
