Including setting up the fire door on the brickwork, the furnace gate is equipped with on the fire door, the sealed chamber of having a perfect understanding the fire door is equipped with on the brickwork, sealed intracavity is equipped with transmission and sliding door, the last opening that is provided with of sliding door. The utility model discloses effectively stoped leaking of burner gas, avoided simultaneously having practiced thrift the energy in the outside air gets into the stove, guaranteed that the work piece adds the thermal mass, has improved work piece heating efficiency.
Description
Technical field
The utility model relates to heating furnace, specifically a kind of heating-furnace door gear.
Background technology
At present such as multilayer rotary hearth furnace, push-plate furnace door many employings entirety open form, though like this dress, get individual layer part in stove, also need to open completely, furnace gas leaks in a large number, causes waste; The outer large quantity of air of stove enters burner hearth from fire door Lower Half simultaneously, and cause carbon potential in short time stove to decline to a great extent, affect workpiece quality time serious, the carbon potential of decline needs again to pass into a large amount of enriched gas to compensate, and causes repetition and waste.Furnace sealing tightly depends on single fire door, and fire door panel is easily out of shape, and causes furnace gas to reveal.
Utility model content
The utility model is intended to solve the problem, thus provides a kind of and can effectively stop furnace gas to leak, avoids outside air to enter in stove, improves the heating-furnace door gear of workpiece heat efficiency and heating quality.
The utility model solves described problem, and the technical scheme of employing is:
A kind of heating-furnace door gear, comprise the fire door be arranged on furnace wall, fire door is equipped with fire door, furnace wall is equipped with the annular seal space of through fire door, annular seal space, built with transmission device and sliding door, sliding door is provided with opening.
Adopt the utility model of technique scheme, compared with prior art, its outstanding feature is:
1. slided in annular seal space by sliding door, the opening on sliding door slides into the workpiece layer position needing to pass in and out stove, for the turnover stove of workpiece, effectively prevent leaking of furnace gas, avoid outside air to enter in stove simultaneously, saved the energy, improve workpiece heat efficiency.
2. by sliding door and fire door double-layer sealing structure, ensure that workpiece heat quality, it also avoid existing heating furnace and tightly depend on single fire door and the situation causing fire door panel deformation.
As preferably, the utility model further technical scheme is:
Annular seal space is inclined to be arranged in furnace wall, utilizes sliding door body self gravitation to be pressed on the inclined-plane of annular seal space, makes its surrounding reach sealing state.
Openings of sizes is 1/4 ~ 1/3 of fire door size, at utmost reducing leaking of furnace gas, avoiding outside air to enter in stove when opening sliding door.
Fire door is complete sealed construction, fire door cooperation place is provided with sealing ring, fire door is provided with air-cylinder compressing device, makes fire door reach whole sealing.
Fire door place is provided with cooling device, reduces the distortion that fire door temperature influence occurs, and keeps sealing.
The outer wall groove structure in the form of a ring of fire door, endless groove structure is set with cooling device.
Transmission system is chain drive structure, by chain pull sliding door move in annular seal space needed for go out part position.
Accompanying drawing explanation
Fig. 1 is the utility model example structure schematic diagram.
In figure: heating furnace furnace wall 1, transmission system 2, chain 3, annular seal space 4, sliding door 5, workpiece 6, opening 7, air-cylinder compressing device 8, fire door 9, fire door 10, sealing ring 11, cooling device 12.
detailed description of the invention:
Below in conjunction with embodiment, the utility model is described in further detail, and object is only to understand the utility model content better, and therefore, the cited case does not limit protection domain of the present utility model.
See Fig. 1, inclination heating furnace furnace wall 1 is equipped with and the annular seal space 4 of through fire door 9, transmission system 2 and the sliding door 5 of chain drive structure is provided with in annular seal space 4, sliding door 5 can be slided by the chain 3 of transmission system 2 in annular seal space 4 inclined plane, sliding door 5 self gravitation is utilized to be pressed on the inclined-plane of annular seal space 4, its surrounding is made to reach sealing state, sliding door 5 is provided with opening 7, opening 7 size is 1/4 of fire door 9 size and adapts with workpiece 6 size and arrange, slided by sliding door 5 tilted upward, opening 7 is slid into needs to pass in and out the workpiece layer position of stove, for the turnover stove of workpiece 6, at utmost reduce leaking of furnace gas, outside air is avoided to enter in stove, fire door 10 is complete sealed construction, fire door 9 cooperation place is provided with sealing ring 11, fire door 9 is provided with air-cylinder compressing device 8, fire door 10 is made to be pressed on fire door 9 place, reach and seal completely.Fire door 9 place is provided with cooling device 12, in the cooling chamber of cooling device 12 by recirculated water, oil or air to reach the object of cooling fire door 9, reduce the distortion of fire door 9 temperature influence appearance, and keep sealing.
When keep forging ahead workpiece 6 time, open fire door 10, the sliding door 5 in annular seal space 4 is driven by the chain 3 of transmission system 2, opening 7 on sliding door 5 is moved to need into stove or the workpiece layer of coming out of the stove, sliding door 5 body self gravitation is utilized to be pressed on the inclined-plane of annular seal space 4, its surrounding is made to reach sealing state, furnace gas can only be passed in and out by opening 7, because the aperture of opening 7 is very little, for 1/4 of fire door 9 size, effectively prevent leaking of furnace gas, avoid outside air to enter in stove simultaneously, save the energy, ensure that workpiece 6 heating quality, improve the efficiency of heating surface, fire door 10 is complete sealed construction, fire door 9 is made to reach whole sealing by air-cylinder compressing device 8 and sealing ring 11, the cooling device 12 being arranged on fire door 9 place effectively reduces the distortion of fire door 9 and fire door 10 panel temperature influence, and keep sealing.
The foregoing is only the better feasible embodiment of the utility model, not thereby limit to interest field of the present utility model, the equivalence change that all utilization the utility model descriptions and accompanying drawing content thereof are done, be all contained within interest field of the present utility model.
