Hazardous chemical type, quantity are continuously increased, and poisonous and harmful substance is treated as the most important thing of protection environment.Waste incinerator
When combustion chamber operational, a large amount of high-temperature harmful gas are generated, in order to protect the health of operator with surrounding ecological environment from dirt
Dye, it is necessary to prevent equipment at work, the high temperature harmful smoke in furnace is to outward leakage.The indoor fire grate one of waste incinerator burning
As points three sections, the disposed waste by various processing is put on fire grate from feeding port from top to bottom, passes through heating, burning, residue
The techniques such as processing, the movement of fire grate be by furnace body outside motor drive and have the main axis of cam, in the change by slide bar
It mutually moves, so that the mode of slow fire grate generation, interruption, shake is travelled forward, make rubbish full combustion to be processed.But in cunning
During bar moves, part pernicious gas is easy to leak from sliding pole axis and air seal contact surface, causes certain
Therefore harm needs to design a kind of new technical solution, solve problems of the prior art with comprehensive.
Utility model content
The utility model patent aims to overcome that above-mentioned the deficiencies in the prior art, and providing one kind prevents nocuousness
Box device is protected in gas secondary leakage air seal, and structure is simple, and use is safe, can effectively solve existing in the prior art
Pernicious gas passes through sliding pole axis leakage problem.
In order to reach above-mentioned purpose of utility model, the utility model solves technical problem and adopts the following technical scheme that one kind
Prevent pernicious gas secondary leakage air seal from protecting box device, including sliding pole axis, main cartridge, sealing ring, seal groove, spiral shell
Nail, connecting plate, adapter tube, air seal.
Preferably, the sliding pole axis outer ring is provided with main cartridge, and sealing ring, institute are provided in the seal groove of the main cartridge
It states sealing ring and is close to sliding pole axis arrangement, the outer surface of the sealing ring is provided with main cartridge seal groove, under the main cartridge
It is additionally provided with air seal on the sliding pole axis outer ring of side, is provided with connecting screw between the main cartridge and air seal.
Preferably, the sealing ring is fixed on above the main cartridge by seal groove；
Preferably, adapter tube one end setting is connected with main cartridge, is provided with installation bayonet below the main cartridge, described
Installation bayonet mating connection plate is mounted on the upper surface of the air seal；
Preferably, one end of the main cartridge is fixed on above air seal, the other end of main cartridge by connecting plate with
Sealing ring is connected.
The utility model has the following beneficial effects:
One kind prevents pernicious gas secondary leakage air seal from protecting box device, by sealing ring, adapter tube, main cartridge and gas
Sealing is combined together, and the gas for sealing cavity pressure is slightly above by adapter tube input pressure, so that sliding pole axis is during exercise, energy
Prevent high-temperature harmful gas from revealing from air seal upper end.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Embodiment 1
Present embodiments providing one kind prevents pernicious gas secondary leakage air seal from protecting box device, including sliding pole axis 1,
1 outer ring of sliding pole axis is provided with main cartridge 2, and the top of the main cartridge 2 is provided with seal groove 4, in the seal groove 4
Sealing ring 3 be close to the sliding pole axis 1 and arrange, the outer surface of the sealing ring 3 is provided with main cartridge 2, and the main cartridge 2 is arranged
It is connected with adapter tube 7, connecting plate 6 is provided with below the main cartridge 2 and is connected by screw 5 with air seal 8.Gas is connect by described
Pipe 7 is entered the main cartridge 2 and is supported the part institute body leaked out except the air seal 8 using pressure difference, prevents harmful gas to reach
The secondary leakage of body.The sealing ring 3 can effectively solve the problem that the flat seal problem between the sliding pole axis 1 and protecting box, protect
Opposing seal effect is demonstrate,proved, the safety in utilization and operational stability of the utility model are improved.
The preferred further embodiment of the present embodiment, when gas is entered in protecting box by the adapter tube 7, in slide bar
Axis 1, main cartridge 2, keeps the pressure to balance each other in the opposing seal space between air seal 8 at sealing ring 3, this pressure is slightly higher
In air seal cavity pressure, to form pressure chamber at 1 position of the sliding pole axis that the air seal 8 is also easy to produce leakage
Body makes gas leakage that can not overflow air seal 8 to reach the sealing function for preventing pernicious gas secondary leakage.
Working principle: one kind provided by the utility model prevents pernicious gas secondary leakage air seal from protecting box device,
A gas pressure chamber is formed by sliding pole axis, sealing ring, main cartridge, gas-tight sealing, so that air seal is in sliding pole axis
When axially or radially swinging, the pernicious gas for preventing part from overflowing is revealed.
The sequencing of above embodiments is not only for ease of description, represent the advantages or disadvantages of the embodiments.
