Abstract
The invention discloses an electric push rod furnace door sealing device which comprises a stand column. The stand column is movably connected with a supporting rod, the connecting end of the supporting rod is connected with a pressing plate of a pressing wheel, when a furnace door is closed, an electric push rod pushes the free end of the supporting rod outwards, and the pressing wheel is made to press the sealed furnace door. The electric push rod furnace door sealing device has the advantages that operation is convenient, cost is low, and the furnace door sealing effect is good. According to an optimal technical scheme, the pressing plate is bent from outside to inside, so that the sealing device has the advantages that in the furnace door sealing process, the influence of the furnace door on the counter-acting force of the pressing plate is lowered to the minimum, and the inward acting force of the pressing plate is given to full play.
Description
Technical field
The fire door obturator technical field that the present invention relates to industrial furnace, especially relates to a kind of device that adopts the airtight fire door of electric pushrod.
Background technology
Industrial furnace is mainly made up of major parts such as body of heater (comprising furnace lining), heater, heated air circulation device, chassis, transmission device for bogie, fire door, heat abstractor, sealing device, temperature control and register system, dynamical systems, mostly adopts the full alumina silicate refractory fiber cotton with good heat preservation and insulation for the furnace lining in body of heater.
Fire door is one of vitals of industrial furnace, is bearing and is opening and airtight function.At present, in industrial furnace technical field, mostly adopt vertical lift mode to open and close fire door, but affected the obturation effect of fire door as the mode of releasing this kind of bright keying fire door in Chinese patent literature CN201476568U.
Therefore, be necessary to develop a kind of cost low, the fire door obturator good to fire door obturation effect.
Summary of the invention
The technical problem to be solved in the present invention is to provide easy to operate, and cost is low, to preferably fire door obturator of fire door obturation effect.
For solving the problems of the technologies described above, the technical solution used in the present invention is this electric pushrod fire door obturator, include column, on described column, be connected with pole, the link of this pole is connected with the pressing plate with pinch roller, when fire door is airtight, the electric pushrod of peripheral hardware promotes the free end of pole outward, makes pinch roller compress airtight fire door.
Adopt the electric pushrod fire door obturator of said structure, owing to being connected with pole on column, like this, when fire door is airtight, electric pushrod promotes the free end of pole outward, pole will be with dynamic pressure plate inwardly, and the pinch roller that compresses fire door is just arranged on pressing plate, the beneficial effect of its generation is can effectively control pole by this flexible connection, the mode of this flexible connection has various ways, can be rotating shaft form or other equivalents.
As a further improvement on the present invention, described pressing plate is from outer toward interior bending.Adopt the beneficial effect of such its generation of structure to be, make in the process of airtight fire door, can be by fire door the impact of the reaction force on pressing plate drop to minimumly, give full play to the inside active force of pressing plate.
As a further improvement on the present invention, described pinch roller surface is coated with one deck quality of rubber materials.Be coated with one deck quality of rubber materials on pinch roller surface, the beneficial effect of its generation is, in pinch roller contacts and compress the process of fire door, can not cause damage to the surface of fire door.
As a further improvement on the present invention, the end of described column and pole junction is conical.Because column is flexibly connected with pole, no matter pole is outwards or inwards to rotate, all likely contact with column, therefore, taper shape is arranged to in the end of column and pole junction, like this, in pole rotational angle, be can not contact with column, adopt in addition also better appearance of taper shape, also saved cost simultaneously.
As a further improvement on the present invention, near the end of column and the below that is positioned at column is also provided with support column.When electric pushrod promotes pole airtight fire door, due to the stress point of pole with the junction of column, therefore, near the end of column, be also provided with support column, the beneficial effect of its generation is, disperseed stressed a direction of column, extend the service life of column, saved maintenance cost.
Accompanying drawing explanation
Further describe below in conjunction with accompanying drawing and embodiments of the present invention:
Fig. 1 is structural representation of the present invention;
In figure: 1-column, 2-pole, 3-pressing plate, 4-pinch roller, 5-link, 6-free end, 7-end, 8-support column.
The specific embodiment
As shown in Figure 1, the 9th, fire door, this electric pushrod fire door obturator, include column 1, on column 1, be connected with pole 2, near the end 7 of column 1, be also provided with support column 8, the link 5 of this pole 2 is connected with the pressing plate 3 of pinch roller 4, known from accompanying drawing 1, and pressing plate 3 is from outer toward interior bending.
In the present embodiment, described pinch roller 4 surfaces are coated with one deck quality of rubber materials, in order to protect the surface of fire door not to be subject to the scratch of pinch roller; In addition, described column 1 is conical with the end 7 of pole 2 junctions.
When use, fire door is airtight, and electric pushrod outward (Fig. 1 arrow direction) promotes arrow direction in the free end 6(figure of pole 2), pole 2 is with dynamic pressure plate 3 to compress inward fire door, makes the pinch roller 4 on pressing plate 3 compress airtight fire door.
By reference to the accompanying drawings embodiments of the present invention are described in detail above, but the invention is not restricted to above-mentioned embodiment, in the ken possessing at affiliated technical field those of ordinary skill, can also under the prerequisite that does not depart from aim of the present invention, make a variety of changes.
