Description
Technical field
The utility model belongs to road building machine technical field more particularly to a kind of novel dust removing air duct connecting structure.
Background technique
Currently, asphalt mixing plant dedusting air hose generally uses circle, because of fabrication error, frequently result in by drawing making
Pipeline when building site is installed, be not short be exactly to grow, air hose is short will to move bag filter or one with Large-scale Hoisting equipment
Subgravity deduster to reduce distance between the two, but is difficult to accomplish distance just, there will certainly be installation and miss
Difference, air hose grown will scene employ gas cutting equipment and slice off extra part, again after welding production again with bag filter
It being connected with a gravitational precipitator, operates not only intricate operation in this way, field labor is big, equipment appearance is influenced, and
And the set-up time is also increased, virtually increase in-site installation cost.
Utility model content
In order to overcome the disadvantages mentioned above of the prior art, the utility model provides a kind of novel dust removing air duct connecting structure,
It is designed rationally, and structure is simple, using round telescoping tube+conical pipe mode, solves air hose in building-site installation, length
Different problem reduces work on the spot labor intensity, improves installation effectiveness.
In order to achieve the above objectives, the technical solution adopted in the utility model is: a kind of novel dust removing air duct connecting structure, packet
A sequentially connected gravitational precipitator, connection Taper Pipe, telescoping tube, bag filter are included, the flexible length of tube is greater than primary
The distance between gravitational precipitator and bag filter, the connection Taper Pipe end diameter is bigger than flexible pipe diameter, connects Taper Pipe
The same subgravity deduster connection of big end；Described telescoping tube one end welded flange, is bolted by flange and bag filter,
The other end welds the retaining ring of flexible tube end, and gear flange is equipped on the inside of the retaining ring, and the gear flange inner diameter is greater than outside telescoping tube
Diameter and be less than retaining ring outer diameter, with guarantee gear flange can along telescoping tube axis slide without dropping out；It is equipped with and lives on the inside of the gear flange
Flange, the flange outer diameter living and connecting hole are identical as the connection small end flanges of Taper Pipe, and flange inner diameter living is greater than gear flange inner diameter.
Further, the connection Taper Pipe end diameter is 50 millimeters bigger than flexible pipe diameter, is inserted into convenient for telescoping tube
Enter and guarantees that gap is small between the two.
Further, the flange inner diameter living is greater than 10 millimeters of flange inner diameter of gear, guarantees that flange living can not only be along telescoping tube
Axis sliding, and can be rotated along axis, bolt is connected when facilitating installation.
Compared with prior art, the utility model has the following beneficial effects: using round telescoping tube+conical pipe mode, because
Flexible length of tube is greater than the distance between a gravitational precipitator and bag filter, so leading to telescoping tube one end when installation
Flange is crossed to connect with bag filter, the other end is inserted into connection Taper Pipe, by work flange on telescoping tube with connect Taper Pipe
Connection, is also achieved that telescoping tube connect with a gravitational precipitator because flexible length of tube greater than a gravitational precipitator with
The distance between bag filter, so air hose short problem when being not in installation, and because retaining ring, gear flange, flange living
Outer diameter, internal diameter design, enable to keep off flange and be slided along telescoping tube axis, so that gear flange is leaned on proximity Taper Pipe, then passed through
Connecting hole on flange outer diameter living is identical as the connection small end flanges of Taper Pipe, and flange inner diameter living is greater than the design of gear flange inner diameter,
Flange living can not only be as gear flange be in the sliding of telescoping tube axis, but also can rotate along axis, connection when facilitating installation
Bolt, this addresses the problem air hoses, and the problem of slicing off extra part is needed when long.
In short, this structure is simple, using round telescoping tube+conical pipe mode, solve air hose in building-site installation,
Problem different in size reduces work on the spot labor intensity, improves installation effectiveness.
Detailed description of the invention
In order to illustrate the technical solutions in the embodiments of the present application or in the prior art more clearly, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described.
Fig. 1 show the utility model structure diagram；
Fig. 2 show the utility model retaining ring partial enlargement structural representation.
Specific embodiment
It is described in detail below in conjunction with the technical scheme in the embodiment of the utility model:
Referring to Fig.1, shown in 2, a kind of novel dust removing air duct connecting structure, this structure is using round telescoping tube+conical pipe side
Formula, including a sequentially connected gravitational precipitator 3, connection Taper Pipe 4, telescoping tube 2, bag filter 1, the telescoping tube 2 are long
Degree is greater than the distance between a gravitational precipitator 3 and bag filter 1, and 4 end diameter of connection Taper Pipe is more straight than telescoping tube 2
Diameter is 50 millimeters big, and the same subgravity deduster 3 of connection 4 big end of Taper Pipe connects, and guarantees that telescoping tube 2 is inserted into connection Taper Pipe 4
It is interior, air hose short problem when being not in installation；2 one end connecting flange of telescoping tube is welded, and passes through flange and bag-type dust
Device 1 is bolted, and the other end welds 2 end retaining ring 7 of telescoping tube, and telescoping tube is equipped on the inside of retaining ring 7 and keeps off flange 6, gear 6 internal diameter of flange omits
It is less than 7 outer diameter of retaining ring, greater than 2 outer diameter of telescoping tube to guarantee that gear flange 6 can be slided along 2 round tube axis of telescoping tube without dropping out；
Flange 5 living is equipped on the inside of the gear flange, 5 outer diameter of flange and connecting hole living are identical as the connection small end flanges of Taper Pipe 4, and internal diameter is big
In about 10 millimeters of 6 internal diameter of flange of gear, guarantee that flange 5 living can not only be slided along round tube axis, and can rotate along axis, with convenient
Bolt is connected when installation.
Working principle of the utility model is:
In building-site installation, bag filter 1 and a gravitational precipitator 3 are first placed on ground corresponding position,
2 movable end of telescoping tube is put into connection 4 small end of Taper Pipe；Two pieces is sling together with crane, respectively with 1 flange of bag filter and
No. one time 3 flange of gravitational precipitator is connected with, and moves gear orchid 6 along round tube axis, make its with to connect the small end flanges of Taper Pipe 4 tight
Patch；Mobile flange 5 living again, is close to gear flange 6, then rotation orchid 5 living, connects its connecting hole with the small end flanges of Taper Pipe 4 are connect
It is perfectly aligned to connect hole, then uses bolt fastening.
The above is only the specific embodiment of the application, it is noted that is the ordinary skill people of the art
For member, under the premise of not departing from the application principle, several improvements and modifications can also be made, these improvements and modifications are also answered
It is considered as the protection scope of the application.
