Enlarged drawing at enlarged drawing and D at enlarged drawing, C.
The utility model is provided in a kind of specific embodiment of gas screen casing, including outer tube 1 and is inserted in the outer tube 1
In inner tube 2.Inner tube 2 is with being equipped with through hole 4 on outer tube 1, and the through hole 4 in inner tube 2 is set with the face of through hole 4 on outer tube 1,
That is, after inner tube 2 and outer tube 1 assemble, the through hole 4 in inner tube 2 and the face of through hole 4 on outer tube 1.One end in outer tube 1
Provided with for inner tube 2 carry out axial limiting boss, i.e., when inner tube 2 is installed into outer tube 1, inner tube 2 from outer tube 1 one
Individual port enters, and the end of inner tube 2 can prop up the boss, so as to avoid inner tube 2 from setting one end of boss to take off from outer tube 1
Go out.Wherein, it can be coordinated between inner tube 2 and outer tube 1 with small―gap suture, make inner tube 2 not by radial load so as to which radial motion will not be produced,
So connect very simple and convenient
It can be seen that the gas screen casing in the present embodiment improves compression strength using twin-tube type structure, reliability is higher, together
When, the setting of the inner convex platform of outer tube 1 can facilitate the installation of inner tube 2, be advantageous to improve the convenience of installation.
Specifically, gauze 3 can be provided between outer tube 1 and inner tube 2.When mounted, gauze 3 first can be enclosed on inner tube 2
Outer surface, then inner tube 2 and gauze 3 are fitted into outer tube 1 jointly, pay attention to ensureing the through hole 4 and outer tube 1 of inner tube 2 during inserting
Through hole 4 aligns.
Gauze 3 is provided with the gas screen casing that the present embodiment is provided, gauze 3 can filter coal particles, prevent coal particles
Extraction system is blocked in into gas screen casing.
Specifically, circumferentially arranged with several through holes 4 on outer tube 1, and the through hole 4 on outer tube 1 is circumferentially staggered setting.
Wherein, the central point for referring to two adjacent in the circumferential through holes 4 is circumferentially staggered in the side parallel to the central shaft of outer tube 1
There is the spacing more than zero upwards.Through hole 4 in inner tube 2 is set due to needing with the face of outer tube 1, thus the through hole 4 in inner tube 2
There is identical arrangement mode with outer tube 1.The arrangement mode of through hole 4 may further ensure that the anti-of gas screen casing in the present embodiment
Compressive Strength.
Specifically, can be easy on outer tube 1 along the direction parallel to the central shaft of outer tube 1 with several through holes 4 of spaced set
Installation, and it is convenient for the extraction of gas.
Specifically, outer tube 1 and the through hole 4 in inner tube 2 can be slotted hole, and the length direction of slotted hole is parallel to outer
The central shaft of pipe 1.Because length of the outer tube 1 with inner tube 2 in the axial direction is larger, the direction setting of slotted hole can in the present embodiment
It is easy to the area of slotted hole being arranged to higher value while the intensity of gas screen casing is ensured, to improve gas pumping efficiency,
And it is not susceptible to block.
It can be provided with the basis of above-mentioned each embodiment, on boss and be used to coordinate the recessed of grafting with the end of inner tube 2
Groove, when inner tube 2 is inserted in outer tube 1, the end of inner tube 2 can be plugged on groove, so as to further improve inner tube 2 in outer tube
The stability placed in 1.
On the basis of above-mentioned each embodiment, the both ends of outer tube 1, which can be provided with, to be used to connect with what other outer tubes 1 docked
First 5, to facilitate the progress of the attended operation between outer tube 1.Inner tube 2 is connected with outer tube 1, in the joint 5 of outer tube 1 can also limit
Pipe 2 moves axially.
Further, joint 5 is specifically as follows threaded portion or adhesive portion, to realize rapid abutting joint.
Each embodiment is described by the way of progressive in this specification, what each embodiment stressed be and other
