Abstract
The invention discloses a furnace bottom sealing device for a car-type heating furnace. The furnace bottom sealing device is realized by adopting the technical measures that the furnace bottom sealing device for the car-type heating furnace comprises a sealing groove and a sealing cutter, wherein the bottom of the sealing groove is in shaft hinge with the upper end of a connecting rod through a hinge; the lower end of the connecting rod is in shaft hinge with a fixed plate through a hinge; the fixed plate is fixed on a furnace body; a thrust member is fixed on the side wall at the bottom of the car-type furnace and can be used for pushing the connecting rod to rotate around the lower end of the connecting rod along with the movement of the bottom of the car-type furnace; and the sealing cutter is fixedly arranged on the furnace body. By adopting the technical scheme, the furnace body can be completely isolated from outside air, energy loss is reduced and the grade of products of the car-type heating furnace is effectively improved; and the traditional products can be processed and the quenching and tempering processing of die parts can be realized, thus the market space is opened up and the benefits of enterprises are increased.
Description
Technical field
The present invention relates to a kind of trolley type heating furnace, relate in particular to a kind of furnace bottom sealing device of trolley type heating furnace.
Background technology
The sealing of traditional car type furnace furnace bottom, employing be the method for sand seal, design has sand sealing groove at the bottom of the car type furnace, design has sand sealing knife on body of heater.When using, along with entering body of heater at the bottom of the car type furnace, the sand sealing knife at the bottom of the car type furnace is promptly cut in the sand sealing groove on the body of heater, is connected as a single entity by sand sealing groove with body of heater at the bottom of making car type furnace, reaches the isolation of body of heater and outside air, plays the effect of sealing.Owing to using for a long time, the sealing sand flow in the sand sealing groove loses, and between sand grains and the sand grains a lot of spaces is arranged, and extraneous air can enter body of heater by the space between sand grains, makes heated part generation oxidation and decarbonization and influences product quality.The sealing of car type furnace furnace bottom is the technical barrier of car type furnace application facet always.Never obtain for many years effectively to solve.So trolley type heating furnace is because sealing problem, it can only be used for the processing of low-end product, as the annealing of forging, structural member eliminate stress the heating of blank etc.
Summary of the invention
The present invention be directed to the existing in prior technology shortcoming, and provide a kind of technical scheme of furnace bottom sealing device of trolley type heating furnace, adopt the sealing device that body of heater and outside air are isolated fully, reduced energy loss, improve the product specification of trolley type heating furnace effectively, except that can carrying out traditional product processing, also can carry out the quenching and tempering processing of mould parts, open up the market space, increased the performance of enterprises.
The present invention realizes by following technical measures: a kind of furnace bottom sealing device of trolley type heating furnace, comprise seal groove, sealing cutter, the bottom of described seal groove is hinged by the upper shaft of hinge and connecting rod, the lower end of described connecting rod is hinged by hinge and fixed head axle, described fixed head is fixed on the body of heater, be fixed with thrust piece on the described car type furnace downside wall, described thrust piece can be rotated around its lower end with the mobile promotion connecting rod at the bottom of the car type furnace; Described sealing cutter is fixedly mounted on the body of heater.
Concrete characteristics of the present invention also have, and are respectively arranged with connecting rod on the body of heater of both sides at the bottom of the above-mentioned car type furnace, and the connecting rod of every side has two at least, and a connecting rod wherein is provided with driving mechanism.
The connecting rod of above-mentioned every side has four.
Above-mentioned seal groove is built-in with refractory fibre.
Above-mentioned thrust piece comprises the push pedal that is fixed on a side at the bottom of the car type furnace, fixedly is connected with the thrust bolt in the described push pedal.
Beneficial effect of the present invention is: it is simple in structure, design is ingenious, adopt this technical scheme can body and outside air isolate fully, reduced energy loss, improved the product specification of trolley type heating furnace effectively, except that can carrying out traditional product processing, also can carry out the quenching and tempering processing of mould parts, open up the market space, increase the performance of enterprises.

Fig. 3 is the partial enlarged drawing among the figure.
Among the figure, 1, refractory fibre, 2, the sealing cutter, 3, seal groove, 4, fixed head, 5, at the bottom of the car type furnace, 6, push pedal, 7, the thrust bolt, 8, connecting rod, 9, driving mechanism, 10, body of heater, 11, hinge, 12, hinge.
The specific embodiment
For clearly demonstrating the technical characterstic of this programme, below by a specific embodiment, and in conjunction with it
Accompanying drawing is set forth this programme.
As shown in drawings, the present invention is a kind of furnace bottom sealing device of trolley type heating furnace, comprise seal groove 3, sealing cutter 2, the bottom of described seal groove 3 is hinged with the upper shaft of connecting rod 8 by hinge 11, the lower end of described connecting rod 8 is hinged by hinge 12 and 4 of fixed heads, described fixed head 4 is fixed on the body of heater 10, is fixed with thrust piece on the described car type furnace downside wall, and described thrust piece can be rotated around its lower end with the mobile promotion connecting rod at the bottom of the car type furnace; Described sealing cutter 2 is fixedly mounted on the body of heater 10.Be respectively arranged with connecting rod 8 on the body of heater 10 of both sides at the bottom of the car type furnace, the connecting rod of every side has two at least, and a connecting rod wherein is provided with driving mechanism 9.3 meters of the sealing flute length that adopts in the specific embodiment, uniform four connecting rods in front and back, length of connecting rod 300mm, seal groove 3 is built-in with refractory fibre 1.
Wherein, thrust piece comprises the push pedal 6 that is fixed on a side at the bottom of the car type furnace, fixedly be connected with thrust bolt 7 in the described push pedal 6, determine the peak that seal groove can reach by the fixed position of adjusting the thrust bolt, the thrust bolt also plays the effect of the fine adjustment of seal groove height simultaneously.
Adopt this technical scheme, when seal groove 3 idle words, about 30 degree angles turn forward, at this moment, the sealing cutter 2 that seal groove 3 breaks away from the body of heater, can freely enter body of heater 10 at the bottom of the car type furnace, at the bottom of car type furnace, install part, in the process that enters body of heater 10, push pedal 6 at the bottom of the drive car type furnace and the thrust bolt 7 that is fixed in the push pedal 6 move, one end of thrust bolt is against on the connecting rod 8, promotes connecting rod 8 and rotates, and seal groove 3 is risen, when arriving the dead point at the bottom of the car type furnace, seal groove 3 also rises to peak, makes the surface of the refractory fibre 1 in the seal groove 3 tightly push down sealing cutter 2 on the body of heater, thereby reaches efficient sealed at the bottom of the car type furnace.
The present invention can pass through existing techniques in realizing without the technical characterictic of describing, and does not repeat them here.Certainly; above-mentioned explanation is not to be limitation of the present invention; the present invention also is not limited in above-mentioned giving an example, and variation, remodeling, interpolation or replacement that those skilled in the art are made in essential scope of the present invention also should belong to protection scope of the present invention.
