Abstract
The utility model relates to an end sealing and cooling structure for ends of furnace rollers in a furnace roller heat treatment furnace. The furnace rollers penetrate through a whole furnace body. Six drive systems are disposed at the end of one side of each furnace roller, outside the furnace body. The furnace rollers are driven by a variable frequency motor, a reducer, sprockets and a chain. A bearing disposed on each bearing block and supports an outer furnace roller of the furnace body. A refractory liner is disposed on the side wall of the steel structure of the furnace body. Each furnace roller covered with refractory fiber is as wide as the refractory liner and insulates heat in the furnace from loss. Furnace roller baffles are mounted on angle steel welded to the steel structure of the furnace body. A seal cover is mounted on a bellows through bolts, the bellows is connected with an intake pipe, space enclosed by the furnace roller baffles, the air bellows and the seal cover plate form a negative pressure cavity, and cold air sucked in cools the ends of the furnace rollers. The end sealing and cooling structure has the advantages that the end sealing and cooling structure is effective in sealing and cooling, simple, convenient to maintain, energy-saving, emission-reducing and low in cost.
Description
Technical field
The utility model belongs to the heat-treatment furnace field, furnace roller end part seal and cooling structure in the furnace roller heat-treatment furnace that particularly a kind of sealing and cooling are good, cost is low.
Background technology
At present, the mode that the furnace roller heat-treatment furnace adopts has the cooling and two kinds of modes of water-cooled of nature, naturally cooling multiplex less demanding in technological temperature, the place to ambient influnence without specific (special) requirements, this kind the mode cost is low, installation is simple, but maintenance capacity is large and need the time longer; Water-cooling pattern is multiplex higher in technological temperature, the place that productive temp is fast, this kind of mode cost is high, sealing requirements is higher, to produce certain impact to body of heater if any revealing, and the uninterrupted use of cooling water can cause the waste of resource, as cooling water is reused, need to build corresponding cooling tower, cooling pond and circulation driving station, thereby caused the corresponding increase of cost.
Summary of the invention
The utility model provides furnace roller end part seal and cooling structure in a kind of sealing and cooling is good, cost is low furnace roller heat-treatment furnace for solving the problem existed in known technology.
The technical scheme that the utility model is taked for the problem existed in the solution known technology is: it comprises hermetically-sealed construction, cooling structure and pipeline structure, it is characterized in that: furnace roller connects whole body of heater, the end of furnace roller side outside body of heater is provided with six groups of drive systems, by variable-frequency motor, reductor, sprocket wheel and chain-driving furnace roller, bearing is arranged on bearing block, supports the outer furnace roller of body of heater; Refractory lining is arranged on the side wall of furnace binding; The refractory fibre and the refractory lining that on furnace roller, wrap up are wide, and the furnace roller baffle plate is installed on the angle steel be welded on furnace binding; Seal cover board is arranged on bellows with bolt, and bellows are connected with air inducing pipeline, and the space under the effect of air-introduced machine, furnace roller baffle plate, bellows and seal cover board surrounded forms negative pressure space.
The utility model can also adopt following technical scheme:
Described refractory fibre is firm with the nylon rope binding, and fits tightly with refractory lining;
Described bellows are the rectangle square steel, are separately positioned on the upper and lower of furnace roller, and the bottom surface of upper air exhaust box is evenly equipped with equidistant aperture.
Advantage and the good effect that the utlity model has are: the operating temperature that reduces the furnace roller end, extended the service life of furnace roller, reduced maintenance capacity, reduce maintenance difficulty simultaneously, thereby the operation that assurance equipment can be steady in a long-term, can also reduce scattering and disappearing of furnace heat, improve the integrated heat efficiency of heat-treatment furnace, energy-saving and emission-reduction.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A sectional structure schematic diagram of Fig. 1;
Fig. 3 is the B section structure for amplifying schematic diagram of Fig. 2.
In Fig. 1-Fig. 3: 1. furnace roller, 2. drive system, 3. bearing, 4. bearing block,
5. refractory lining, 6. furnace binding. 7. refractory fibre, 8. furnace roller baffle plate, 9. angle steel,
10. seal cover board, 11. bellows, 12. air inducing pipelines, 13. air-introduced machines, 14. apertures.
The specific embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows, refer to Fig. 1-Fig. 3.
As shown in Fig. 1-Fig. 3: furnace roller 1 connects whole body of heater, and the end of furnace roller 1 side outside body of heater is provided with drive system 2, and by variable-frequency motor, reductor, sprocket wheel and chain-driving furnace roller, sprocket speed can be carried out electrodeless adjusting according to the productive temp difference; Drive system 2 totally 6 groups drive respectively 187 furnace rollers 1, one end of every furnace roller 1 is equipped with bearing 3, bearing 3 is arranged on bearing block 4, support the outer furnace roller 1 of body of heater, because the heat in body of heater can be conducted heat along furnace roller 1, therefore be enclosed with refractory fibre 7 on furnace roller 1, its refractory fibre 7 is wide with the refractory lining 5 on the side wall that is arranged on furnace binding 6, thereby isolated furnace heat scatters and disappears; Simultaneously, with nylon rope, by refractory fibre 7 binding jail, after in stove, temperature acquires a certain degree, nylon rope blows, and refractory fibre expands naturally, with refractory lining 4, fits tightly, and makes the furnace heat can be not excessive; Described furnace roller 1 connects whole body of heater, and the sealing of furnace roller 1 end and cooling structure can reduce scattering and disappearing of heat effectively, thereby has extended the service life of furnace roller 1, has also avoided the grease on the bearing dry and astringent and the seize phenomenon occurs; Furnace roller baffle plate 8 is welded on the angle steel 9 of furnace binding 6, with furnace roller 1, leaves certain gap, for furnace roller 1 expanded by heating; Seal cover board 10 is fixed by bolts on bellows 11, bellows 11 are the rectangle square steel, be separately positioned on the upper and lower of furnace roller 1, the bottom surface of upper air exhaust box 11 is evenly equipped with equidistant aperture 14, bellows 11 are connected with air inducing pipeline 12, the space that makes furnace roller baffle plate 8, bellows 11 and seal cover board 10 surround under the effect of air-introduced machine 13 forms negative pressure space, the cold wind that air-introduced machine 13 is taken out enters from seal cover board 10 and the gap location of furnace roller 1, the cold air sucked is taken the heat of furnace roller 1 end away, reaches cooling purpose.
Its advantage is: reduce the operating temperature of furnace roller end, extended the service life of furnace roller, reduced maintenance capacity, reduce maintenance difficulty, thereby the operation that assurance equipment can be steady in a long-term can also reduce scattering and disappearing of furnace heat simultaneously, improve the integrated heat efficiency of heat-treatment furnace, energy-saving and emission-reduction.
Above-described embodiment is described preferred embodiment of the present utility model; not scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model, all should fall in the definite protection domain of the utility model claims.
