The inside of the front portion of conduit 2 is mounted in, in the part of suit, is left between the inwall of conduit 2 and the outer wall of sweep-up pipe 3 and is supplied air flow
Gap, the gap is to guide the gas channel 5 that flow to the tail end direction of sweep-up pipe 3 of air, gas channel 5 and airduct 1
Connection, in the afterbody insertion disposal box 4 of conduit 2 and fixed, the residue of absorption is deposited in disposal box 4.
In the present embodiment, the air inlet 6 of the gas channel 5 being connected with airduct 1 is located at the leading section of conduit 2, and in conduit 2
Leading section one joint 7 is installed, joint 7 is stainless joint, and the other end of joint 7 is fixed on sweep-up pipe 3, and joint 7 will
Conduit 2 and sweep-up pipe 3 are sealed connected together.There is in the joint 7 a connection chamber 8, the air inlet 6 of gas channel 5 with connect
Chamber 8 connects, and the entrance for connecting chamber 8 is opened in the side of joint 7, and the entrance for connecting chamber 8 is connected with airduct 1.It is real in order to easy to operate
The portability of existing dust exhaust apparatus, joint 7 adopts snap joint.To be tightly connected between conduit 2 and sweep-up pipe 3 and joint 7, to protect
Air in card airduct 1 is only capable of from air inlet 6 entering inside gas channel 5, will not be from joint 7 and the company of conduit 2 and sweep-up pipe 3
Connect place's leakage.Can be threaded connection between conduit 2 and sweep-up pipe 3 and joint 7, it is also possible to insert in conduit 2 and sweep-up pipe 3
Blend compounds to be adhesively fixed realize simultaneously and seal in the jack of joint 7, and conduit 2 and sweep-up pipe 3 can also be inserted the jack of joint 7
Fixation is inside only sealed by way of interference fit.
The generally cylindric structure of the housing of disposal box 4, by middle cylinder 10 and the top cover 11 and bottom 12 at two ends
Composition, top cover 11 and bottom 12 are removably connected on cylinder 10, to facilitate to clearing up in disposal box 4.
To be tightly connected between top cover 11 and bottom 12 and cylinder 10, avoid the residue for suctioning out to flow out from disposal box 4 and make as far as possible
Into secondary pollution.Can be threaded connection between top cover 11 and bottom 12 and cylinder 10, it is also possible to by the side of interference fit
Formula is sealedly and fixedly connected.
A through hole is provided with the center of bottom 12, the afterbody of conduit 2 enters the inside of disposal box 4, conduit 2 through the through hole
There is certain length in insertion disposal box 4, there is an installation portion 13 outwardly on bottom 12, through hole is located at installation portion
13 center, the mode that conduit 2 is threaded connection is fixed in the installation portion 13 of bottom 12, and installing/dismounting is very convenient, just
In cleaning, the setting of installation portion 13 increased conduit 2 for fixed height, fixes elongated conduit 2 and more consolidates.
Passage 9 is provided with the housing of disposal box 4, in the present embodiment, on top cover 11 and cylinder 10 ventilation is provided with
Hole 9, and filtration 14 is provided with the inwall of top cover 11 and cylinder 10, filtration is preferably adopted and is pasted onto on inwall
Sponge or canvas, the air with residue is entered after disposal box 4, and under the filtration of sponge or canvas, residue can quilt
Stop and be deposited in disposal box 4, the air after filtration is then discharged from multiple passages 9, it is to avoid the residue of sucking-off is from dust
Flow out in case 4 and cause secondary pollution.The volume of disposal box 4 is difficult excessive, mitigation weight, to facilitate operating personnel to guide and support.
The operation principle of the dust exhaust apparatus as shown in Figures 2 and 3, when dust suction is needed, airduct 1 is connected on joint 7, such as
Shown in Fig. 2, air sequentially passes through connection chamber 8 in airduct 1, joint 7, enters at the annular air inlet 6 of the leading section of conduit 2 and lead
It is in annular gas channel 5 between pipe 2 and sweep-up pipe 3 and high to the direction of the tail end of sweep-up pipe 3 along gas channel 5
Speed flowing, makes (air of flowing i.e. in gas channel 5) and the air of the interior flowing of sweep-up pipe 3 in conduit 2 produce an air-flow
Speed difference, when the air stream in conduit 2 reaches the tail end of sweep-up pipe 3, will be presented state as shown in Figure 3.
In the present embodiment, point-blank, i.e., gas channel 5 is equally spaced around the center line of conduit 2 and sweep-up pipe 3
The periphery of sweep-up pipe 3, the tail end of sweep-up pipe 3 is flowed into the air in gas channel 5 along the gas channel 5 of annular.
According to Bernoulli equation：
Air velocity in conduit 2 is VSlightly, the air velocity in sweep-up pipe 3 is VCarefully, P for inner air tube pressure, conduit 2
Interior pressure is PSlightly, the pressure in sweep-up pipe 3 is PCarefully, conduit 2 is Δ P with the pressure difference of sweep-up pipe 3, and C is a constant.
Hypothesis air is that perfect gas, i.e. atmospheric density ρ are constant；Dust exhaust apparatus place to use is constant, i.e. height h is constant,
Gravity acceleration g is constant.I.e.
Δ P=PSlightly-PCarefully
Thus can obtain：
Due to VCarefullyIt is consistently less than VSlightly, i.e.,
Δ P ＜ 0
Finally can draw：After joint 1 connects airduct 1, air inlet 6 and the airduct 1 of gas channel 5 that will be in conduit 2
After connection, a negative pressure relative to sweep-up pipe 3 will be produced at B points conduit 2 as shown in Figure 3, and the air pressure of sweep-up pipe 3 is equal to greatly
Pressure difference is constituted between air pressure, i.e. sweep-up pipe 3 and conduit 2, makes to produce suction at the mouth of pipe of the front end of sweep-up pipe 3, residue is from suction
It is inhaled at the mouth of pipe of the front end of dirt pipe 3, successively reaches conduit 2 and disposal box 4, the stop of sponge or canvas in disposal box 4
Under effect, residue deposition being made in disposal box 4, and making the air after filtration flow out disposal box 4, so as to reach each screw thread is drawn
The purpose of residue in the small diameter bores such as hole, fabrication hole.By taking the gear-box on EMUs as an example, screwed hole thereon and fabrication hole
A diameter of mm, through repetition test, the internal diameter of conduit 2 is preferably 8mm, and the external diameter of conduit 2 is preferably 10mm, sweep-up pipe 3
Internal diameter is preferably 4mm, and the external diameter of sweep-up pipe 3 is preferably 6mm, and a width of of gas channel 5 is about between conduit 2 and sweep-up pipe 3
1mm, the total length of conduit 2 selects to be 270mm that the total length of sweep-up pipe 3 selects to be 200mm that the afterbody of sweep-up pipe 3 is inserted into leads
Pipe 2 is close to middle position, and sweep-up pipe 3 has about 2/3 length to be sleeved on the inside of conduit 2, and the length for having 1/3 stretches out conduit
2 leading section.
In maintenance, if operating personnel link together joint 7 with airduct 1, and by the leading section of sweep-up pipe 3 one by one
In stretching to the screw hole or fabrication hole for needing clear up residue, you can realize the removing of residue in screw hole or fabrication hole,
The cleaning effect of aperture is not only can effectively ensure that, and operation is very easy, can increase substantially operating efficiency, reduces operation
The labour intensity of personnel, it is semiautomatic working mode to change pure manual work mode, and the device itself carries disposal box 4,
The residue for suctioning out can be avoided to cause secondary pollution to equipment and environment, the device significantly improves operating efficiency and as received basis
Amount.
As described above, combining the plan content given by accompanying drawing, similar technical scheme can be derived.In every case it is not de-
From the content of technical solution of the present invention, above example is made any simple modification according to the technical spirit of the present invention, etc.
With change and modification, still fall within the range of technical solution of the present invention.
