Technical field
This utility model relates to the core component mechanical kiln grate furnace in a kind of bulky refuse burning facility, and specifically one
Plant the new type sealing device for mechanical kiln grate furnace.
Background technology
Along with the continuous progress of society, economic sustainable development and the raising day by day of living standard, city and rural area
Refuse production sharply increases, and waste incineration and generating electricity achieves focusing on of domestic waste, at rubbish
Reason facility standardization, standardization, improve human settlement's mass, and the main parts of garbage incinerating system be
Mechanical kiln grate furnace.At present, if the driving means of dynamic fire grate segment must be positioned over the outside of grate furnace casing,
Driving means is connected with grate furnace by connecting rod, and the motion of connecting rod is again compound motion, and grate furnace body
Need to seal, be now accomplished by a sealing device and realize sealing.
Utility model content
The purpose of this utility model is to provide a kind of compound motion that both can guarantee that connecting rod, can guarantee that again sealing is wanted
The new type sealing device asked.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of novel sealing device, including link assembly, dynamic holder assembly, base assembly and seal box:
Described link assembly includes the steel pipe being set on connecting rod, by spring steel plate spiral shell between connecting rod and steel pipe
Tether and connect；Steel duct fills alumina silicate fibre；
Described dynamic holder assembly includes dynamic seat, gland and graphite packing, and steel pipe inserts in dynamic seat, dynamic seat and steel pipe
Between use gland and graphite packing to compress, dynamic seat is connected with gland bolt；
Described base assembly includes base, dividing plate and tabletting, superposition dividing plate in the middle of two laminate one end, uses
It is bolted on base；The described laminate on dynamic seat is inserted in the interval of two laminate the other end；
Described seal box top is provided with air port, and link assembly runs through seal box, and base assembly bolt is fixed
On seal box.
The beneficial effects of the utility model: this utility model utilizes link assembly to stop by gas in seal case
From the gap leakage between connecting rod and steel pipe；Utilize pressing plate, the dividing plate pair moved between holder assembly, base assembly
Inserting, it is achieved labyrinth sealing, base assembly bolt is fixed on seal box, and air port is left on seal box top,
Utilizing seal fan to introduce clean air, the pressure introducing clean air is more than by seal case internal gas pressure, makes
Can not must be leaked by air pollution in seal case, it is achieved reliably seal.

Detailed description of the invention
A kind of novel sealing device, as it is shown in figure 5, include link assembly 1, dynamic holder assembly 2, base group
Part 3, seal box 4；
1, seeing Fig. 1, link assembly 1 is mainly made up of the steel pipe 12 of the outer surface cover of connecting rod 11, connecting rod 11 He
Use spring steel plate 13 bolt to connect between steel pipe 12, so can offset connecting rod tiny in motor process
Rotary motion so that keep relative linear motion between steel pipe 12 with dynamic holder assembly 2；Steel pipe 12 is internal
Fill alumina silicate fibre 14, to stop by gas in seal case from the gap between connecting rod 11 and steel pipe 12
Reveal；
2, seeing Fig. 2, dynamic holder assembly 2 includes that dynamic seat 21, gland 23 and graphite packing 24, steel pipe 12 are inserted
Enter in seat 21, move and between seat 21 and steel pipe 12, use gland 23 to compress with graphite packing 24, graphite plate
Root 24 and steel pipe 12 fit tightly realization and seal, and graphite packing 24 smooth surface simultaneously can make again close
Relatively slide between seal apparatus and steel pipe 12；
3, seeing Fig. 3-5, base assembly 3 includes base 33, dividing plate 34 and tabletting 32, two laminate 32
Superposition dividing plate 34 in the middle of one end, is fixed by bolts on base 33, forms two-layer interval；
Laminate 22 on dynamic seat 21 is inserted in the interval of two laminate 32 the other end, the size up and down at interval
More than the size up and down of dynamic holder assembly 2, so can realize dynamic holder assembly 2 and move up and down in interval；
Cylindrical Surfaces Contact between steel pipe 12 and dynamic holder assembly 2, can be relative between steel pipe 12 with dynamic holder assembly 2
Slide, have certain angle simultaneously between connecting rod 11 and steel pipe 12, connecting rod 11 can be adjusted and press from both sides with base 33
Angle, to 90 degree, so facilitates the sealing of steel pipe 12 and dynamic holder assembly 2 Cylindrical Surfaces Contact；
4, seeing Fig. 6, seal box 4 is one trapezoidal, and link assembly 1 runs through seal box 4；Dynamic holder assembly 2 with
Between base assembly 3, multilayer steel plates is to inserting, it is achieved labyrinth sealing, and base assembly 3 multilayer steel plates superposition is empty
Leave sufficient size in gap, dynamic holder assembly 2 can in base assembly 3 multilayer steel plates superposition space on move down
Dynamic, base assembly 3 bolt is fixed on seal box 4, and air port 5 is left on seal box 4 top, utilizes and seals
Blower fan introduces clean air, introduces the pressure of clean air more than by seal case internal gas pressure so that sealed
In casing, air pollution can not leak, it is achieved reliably seals.
Above content is only to this utility model structure example and explanation, the skill of affiliated the art
