Description
Technical field
The utility model belongs to dust explosion protection device field more particularly to a kind of deashing inspection socket of dust explosion protection system
Structure.
Background technique
With the development of modern industry, the potentially danger of dust explosion greatly increases.Flameproof technology can prevent from exploding
It is propagated from initial position to other technique units, the generation of " secondary " explosion or system explosion accident is avoided, to mitigate explosion
Disaster.
Dust explosion protection system is workpiece under defined manufacturing condition, and the dust of generation is set by workbench and dedusting
Outdoor process is discharged to by air hose pipe safety after standby dedusting is up to standard.Normal operation of the structure and state of air hose pipeline to system
Play an important role, reduce the resistance of ducting and guarantee inside pipeline it is clean without dust be system safety operation guarantee.At present
The same industry generallys use the structure that flange port is opened up on pipeline as deashing inspection socket, and bolted flange is periodically opened manually
It the state of lid observation pipeline and is cleared up, this traditional deashing inspection structure high altitude operation is of long duration, labor intensive resource
Greatly, and after being dismounted for multiple times the situation locally revealed can occur, system effectiveness is caused to decline, system operating risk improves.
Utility model content
In order to overcome the above problem, the deashing that the utility model provides a kind of dust explosion protection system checks mouth structure, solves
The above problem existing for existing deashing inspection structure.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of deashing inspection of dust explosion protection system
Mouth structure, including main pipeline are provided with an opening right above the main pipeline, and opening is fixed with a maintenance weldment, described
It is provided on maintenance weldment by the closed maintenance door of main pipeline opening, and for maintenance door side to be mounted on maintenance weldment
On hinge, the other side of the maintenance door is equipped with locking member；The inside of the maintenance weldment is equipped with flange, installs on flange
There is wear-resistant seal adhesive tape.Above-mentioned locking member includes a pair of of the buckle being fixed on maintenance weldment, be arranged in maintenance door and with card
Detain the connecting shaft matched, and the connecting rod with connecting shaft rotation connection.Preferably, it is additionally provided in maintenance door for the company of placement
The Kato of bar.
Further, maintenance weldment surrounds square, rectangle or circle in opening.Flange is interior along maintenance weldment
Side ring is around setting.
Further, steel clamp is additionally provided on the inside of the wear-resistant seal adhesive tape.The setting of steel clamp can be improved sealing joint strip
The fastness and reliability connecting with flange prevent the generation for causing sealing performance to decline that falls off because of sealing joint strip.Above-mentioned steel clamp
It is substantially u-shaped.
Further, the wear-resistant seal adhesive tape is made by nitrile rubber.
Further, when the maintenance door is closed, which can be in contact with the wear-resistant seal adhesive tape.Specifically,
Maintenance door can impose certain extruding force to wear-resistant seal adhesive tape when closed, to guarantee the overall tightness of device.
Further, the maintenance weldment is welded and fixed with main pipeline.
The utility model has the beneficial effects that
The utility model can effectively solve long-time high altitude operation, and labor intensive is big, and part occurs after being dismounted for multiple times and lets out
The problem of leakage, is open by being arranged in the surface of main pipeline, and dust will not be gathered access hole inner dead space by gravity,
It works on main pipeline convenient for staff, by rotary fastenings, compresses wear-resistant seal adhesive tape using maintenance door.This reality
There is durable, structurally reasonable advantage with novel, and improve the safety of system, reduce the cleaning cost of overhaul.
Below with reference to drawings and examples, the utility model is described in detail.
Detailed description of the invention
Fig. 1 is the perspective view of the utility model.
Fig. 2 is the cooperation schematic diagram of flange and steel clamp.
Fig. 3 is structural schematic diagram when maintenance door is closed.
Specific embodiment
Embodiment,
As shown in Figures 1 to 3, a kind of deashing of dust explosion protection system checks mouth structure, including main pipeline 1, the main pipeline 1
Surface be provided with an opening, opening is welded with a maintenance weldment 2 for surrounding " mouth " font, sets on the maintenance weldment 2
It is equipped with the closed maintenance door 4 of main pipeline opening, and the hinge 3 for being mounted on 4 side of maintenance door on maintenance weldment,
The other side of the maintenance door 4 is equipped with locking member 5.
The inside for overhauling weldment 2 is equipped with flange 7, is equipped with wear-resistant seal adhesive tape 6 on flange 7.In wear-resistant seal adhesive tape 6
Inside be additionally provided with steel clamp 12.Above-mentioned steel clamp 12 is substantially u-shaped, and wear-resistant seal adhesive tape 6 is made by nitrile rubber.
Above-mentioned locking member includes a pair of of the buckle 8 being fixed on maintenance weldment, is arranged in maintenance door and matches with buckle
The connecting shaft 9 of conjunction, and the connecting rod 10 with connecting shaft rotation connection.The Kato for disposing connecting rod 10 is additionally provided in maintenance door
11。
Flange 7 is in " mouth " font around setting along the inside of maintenance weldment.
When maintenance door is closed, which can be in contact with the wear-resistant seal adhesive tape.Specifically, maintenance door is being closed
When certain extruding force can be imposed to wear-resistant seal adhesive tape, to guarantee the overall tightness of device.
The utility model is exemplarily described in conjunction with attached drawing above.Obviously, the utility model implements not
It is limited by aforesaid way.As long as the various unsubstantialities that the method concept and technical solution that use the utility model carry out
Improvement；Or it is not improved, the above-mentioned conception and technical scheme of the utility model are directly applied into other occasions, at this
Within the protection scope of utility model.
