The specific embodiment

Below in conjunction with the drawings and the specific embodiments, the utility model is described in further detail.

As Figure 1-3, utility model comprises dust exhaust apparatus and collector 8.

Dust exhaust apparatus comprises a lid 1, bindiny mechanism, nozzle 6, sprays syringe needle 9 and suction pipe 7a.

The middle part of lid 1 upper surface is provided with a boss, and edge is provided with suction port 2, and the upper surface middle part of boss is provided with air inlet 3, and on boss, the side relative with suction port 2 is provided with the nozzle 6 that stretches into lid 1 inside.

Air inlet 3 tops are connected with the bindiny mechanism being connected with air pressure pump, comprise a quick connector 5a, an air valve 5b with handle 5d and between each parts of filter 5c，Gai bindiny mechanism be tightly connected.

Air inlet 3 belows are fixed with sprays syringe needle 9, and spraying syringe needle 9 be fusiformis, and rear end is fixed on lid 1, and front end stretches in the passage of nozzle 6, and air inlet 3 be positioned at this fusiformis injection syringe needle 9 slightly to the back-end position directly over.

The lower surface of nozzle 6 passages is provided with the jet body 10 of tubular structure, and one end is communicated with the passage 61 that sprays syringe needle 9 front end positions, and one end is communicated with the opening of collector 8.

Nozzle 6 passage lower surfaces and the outside that is positioned at jet body 10 are provided with an O type ring 11, are in communication with the outside.

One end of suction port 2 connected sucking pipe 7a, the end of suction pipe 7a connects a suction nozzle 7b.。

Described collector 8 upper end open, the inner spatial accommodation that forms.

WeiVXing edge, the lower end 1a of lid 1, is sealedly connected on the opening of collector.

Boss 3 upper surfaces are fixed with a handle 4.

The course of work of the present utility model is: on quick connector 5a, connect air pressure pump, open the handle 5d on air valve 5b, there is the air of certain pressure intensity to be entered in lid by air inlet 3 by bindiny mechanism, under air inlet 3, be that fusiformis is sprayed syringe needle 9, compressed air meet to spray that syringe needle 9 is rear to be sprayed in the passage of nozzle 6 along its upper surface, a small amount of air is spraying the front end place convolution of syringe needle 9, one small part flows into collector 8 by jet body 10, another part overflows by O type ring 11, this process meets Venturi effect, therefore spray syringe needle 9 rear ends, produce a region of no pressure, region of no pressure makes in collector 8, there is certain vacuum, collector 8 is by suction port 2 and suction pipe 7a, make suction nozzle 7b place produce pull of vacuum and draw foreign material.

When the foreign material of this dust catcher absorption are liquid, can connect the anti-spilled device of a liquid at lid lower surface, this device is arranged in collector 8, upper end is a peviform fixing metal structure 8a, and upper edge 8b and lid 1 middle part are tightly connected, make lid 1 and this peviform fixing metal structure 8a form a confined space, spray syringe needle 9 and be positioned at this space, air inlet is in communication with the outside by nozzle, the bottom surface of peviform fixing metal structure 8a is provided with a blow vent 8c, the surrounding of blow vent 8c is provided with a plurality of support column 8d, the lower end of support column 8d is fixed on a supporting plate 8e, and in the space surrounding at support column 8d, place a ball float 8f, and supported by supporting plate 8e, the outer surface of the anti-spilled device of liquid is also provided with a pocket filter.

Now, the dust catcher course of work is constant, but liquid is received while expiring in collector 8, ball float 8f rises and blocks blow vent 8c, and collector 8 is no longer communicated with in lid, in collector 8, can not keep certain vacuum again, so dust catcher quits work, prevented overflowing of liquid in collector 8.

When using this gas type industrial dust collector, should be specifically noted that following item:

(1) although this kind of dust catcher is provided with the protection switches such as valve body, because of service condition complexity and other factors, so forbid in use gas outlet to be aimed at the device article of the water funk and high velocity air such as people, electrical equipment.

(2) this dust catcher is not suitable for drawing strong acid, alkali article, but no problem for machined cutting wet goods weak acid, alkali article, has drawn strong acid, alkali article as careless, do clear up in time.

(3) this product work time is to draw exterior object by inhaling into negative pressure in bucket, and during use and gas outlet and air inlet can not be blocked simultaneously, otherwise pressed gas will enter in container, easily produce danger.

(4) this product is Light Aluminum Alloy structure, must not firmly beat, collide with, otherwise will damage the structure of whole device during use.

Above embodiment has been described in detail the utility model, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
