Sealing mechanism for artificial graphite coated sintering furnace

Abstract

The utility model relates to the technical field of sintering furnaces, and discloses a sealing mechanism for an artificial graphite coated sintering furnace, which comprises a sintering furnace mouth, two hinge rods are fixedly connected to the front end of the sintering furnace mouth, a sealing cover is hinged to the inner sides of the two hinge rods through hinge shafts, and the outer wall of the sealing cover is matched with the inner wall of the sintering furnace mouth. The sealing cover, the exhaust pipe and the adjusting valve are arranged, the adjusting valve is opened, the exhaust pipe is connected with the air pump through a pipeline (the pipeline is connected to the inner side of the exhaust pipe in a threaded mode, and the pipeline can be taken down through rotation), so that the exhaust pipe is connected with the air pump through the pipeline. Part of air in the sintering furnace is pumped out, then the adjusting valve is closed, the air pressure is reduced due to the fact that the air in the sintering furnace is reduced, the atmospheric pressure is larger than the air pressure in the sintering furnace, and therefore the sealing cover is tightly pressed on the inner wall of the furnace opening of the sintering furnace, and the sealing performance of the sintering furnace is guaranteed.

[0005] (II) Technical scheme

[0006] The technical scheme for solving the above technical problem of the utility model is as follows:

[0007] A kind of sealing mechanism for artificial graphite cladding sintering furnace, including sintering furnace mouth, the front end of the sintering furnace mouth is fixedly connected with two hinged rods, the inner side of two hinged rods is hinged with sealing cover by hinge shaft, the outer wall of sealing cover is consistent with the inner wall of sintering furnace mouth, sealing cover is communicated with suction base, suction base is communicated with the inside of sintering furnace mouth, suction base is communicated with suction pipe, adjusting valve is provided on suction base.

[0008] On the basis of the above technical scheme, the utility model can also be improved as follows.

[0009] Preferably, the hinge shaft is fixedly connected with a rocker.

[0010] (III) Beneficial effects

[0011] Compared with prior art, the technical scheme of the present application has the following beneficial technical effects:

[0012] The utility model discloses a sealing cover, air extraction pipe and regulating valve are set up, open regulating valve, and air extraction pipe is connected air pump through pipeline (the inner side of pipeline screw thread connection is in air extraction pipe, can take down pipeline through rotation), and the part air of sintering furnace is extracted, and then closes regulating valve, because the air in sintering furnace reduces, so the air pressure reduces, and the atmospheric pressure is greater than the sintering furnace internal pressure, and the sealing cover is pressed tightly in the inner wall place of sintering furnace mouth, thereby guaranteeing the sintering furnace sealing property.

[0015] The technical scheme in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative work belong to the range protected by the utility model.

[0016] In the embodiments, Figure 1 A sealing mechanism for artificial graphite coated sintering furnace is given, which comprises a sintering furnace mouth 1, two hinged rods 2 are fixedly connected to the front end of the sintering furnace mouth 1, a sealing cover 4 is hinged to the inner side of the two hinged rods 2 through a hinge shaft 3, the outer wall of the sealing cover 4 is in close contact with the inner wall of the sintering furnace mouth 1, an air extraction base 5 is communicated with the sealing cover 4, the air extraction base 5 is in communication with the inside of the sintering furnace mouth 1, an air extraction pipe 6 is communicated with the air extraction base 5, and a regulating valve 7 is arranged on the air extraction base 5.

[0017] Through the above setting, first, the outer wall of the sealing cover 4 is tightly attached to the inner wall of the sintering furnace mouth 1 by rotating along the hinged position, then the regulating valve 7 is opened, the air extraction pipe 6 is connected to the air pump through the pipeline (the inner side of the pipeline is screw thread connected to the air extraction pipe 6, and the pipeline can be taken down by rotating), the part air in the sintering furnace is extracted, then the regulating valve 7 is closed, because the air in the sintering furnace reduces, so the air pressure reduces, and the atmospheric pressure is greater than the sintering furnace internal pressure, and the sealing cover 4 is tightly pressed on the inner wall of the sintering furnace mouth 1, thereby guaranteeing the sintering furnace sealing property.

[0018] Refer to Figure 1 Among them, the rocker 8 is fixedly connected to the hinge shaft 3;

[0019] Through the above structure, the sealing cover 4 can be opened by rotating along the hinge position by shaking the rocker 8, avoiding direct contact with the high-temperature sealing cover 4.
