[0001] The utility model relates to the technical field of annealing furnaces, in particular to an annealing furnace that is scald-proof. Background Art

[0002] Annealing is a metal heat treatment process in which the metal is heated to a certain temperature, maintained for a sufficient time, and then cooled at an appropriate rate (usually slow cooling, sometimes controlled cooling). The annealing of the workpiece is usually carried out in an annealing furnace, which is a furnace that can anneal the workpiece.

[0003] The common annealing furnace now includes a furnace body and a furnace door. The furnace door is rotatably set on the furnace body. When the workpiece needs to be annealed, the furnace door is opened, the workpiece is placed in the furnace body, and then the furnace door is closed. The furnace body and the furnace door are sealed, and the workpiece is annealed in the furnace body.

[0004] Regarding the above technical conditions, there is also a defect that when the furnace door of the annealing furnace is opened to take out the processed workpiece, as the furnace door opens, the hot air in the furnace body will escape to the surroundings. Because the staff are very close to the furnace door to take out the material, they will be burned by the escaped hot air.

[0005] Based on this, the utility model designs an anti-scalding annealing furnace to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide an annealing furnace that prevents scalding, so as to solve the above technical problems.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-scalding annealing furnace, comprising a furnace body and a furnace door of the annealing furnace, the furnace door being rotatably arranged on the furnace body, the furnace door covering the furnace body, the furnace body being provided with a heat absorption mechanism, the heat absorption mechanism comprising a conduit, a negative pressure fan, a hydraulic rod and an air pipe, the hydraulic rod being fixedly arranged on the furnace body, two hydraulic rods being arranged on the furnace body, the hydraulic rod being fixedly connected to a fixing plate, the conduit being detachably arranged on the fixing plate, the conduit being divided into a straight tube portion and a guide portion, the straight tube portion being fixedly arranged on the guide portion, the guide portion being connected to the fixing plate, the negative pressure fan being arranged on the straight tube portion, the straight tube portion being fixedly connected to a connecting pipe, the air pipe being fixedly connected to the connecting pipe, and the negative pressure fan being between the guide portion and the connecting pipe.

[0008] Preferably, the guide portion is fixedly provided with a guide plate, and two guide plates are provided on the guide portion, and the two guide plates are respectively provided on both sides of the guide portion.

[0009] Preferably, the guide tube is arranged obliquely on the furnace body.

[0010] Preferably, a dust filter is detachably provided on the guide portion.

[0011] Preferably, the guide portion is fixedly connected to a mounting plate, the mounting plate is provided with a fixing hole, a plurality of fixing holes are provided on the mounting plate, the fixing hole is threadedly connected to a threaded rod, and the threaded rod is threadedly connected to the fixing plate.

[0012] In summary, the present application has the following beneficial technical effects: when the workpiece in the furnace body needs to be taken out, the negative pressure fan is started first, and the negative pressure fan generates negative pressure wind force, which sucks the air into the guide part of the duct. The air then passes through the negative pressure fan, the connecting pipe and the air pipe in sequence. At this time, when the furnace door is opened, the hot air escapes from the furnace body. Due to the negative pressure wind force generated by the negative pressure fan, the hot air escapes from the furnace body and is sucked into the guide part by the negative pressure fan. Then the hydraulic rod is started to adjust the distance between the duct and the furnace body, so that the duct can better absorb the hot air escaping from the furnace body. At this time, the staff stands on the side of the furnace body away from the duct to perform the work, and the staff is not easily scalded by the hot air, thereby achieving the effect of making the staff not easily scalded by the annealing furnace.

[0021] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] The following is combined with Figure 1-5 This application is described in further detail.

[0023] A scalding-proof annealing furnace comprises a furnace body 9 and a furnace door 8 of the annealing furnace. The furnace door 8 is rotatably arranged on the furnace body 9 and covers the furnace body 9. A heat absorption mechanism is provided on the furnace body 9. When the furnace door 8 is opened to take out the steel pipe in the furnace body 9, a large amount of hot air will escape from the furnace body 9 into the air. At this time, the heat absorption mechanism can be opened to absorb the escaped hot air, thereby reducing the air escaped from the furnace body 9 to the surroundings. In this way, workers are not easily scalded by the hot air escaped from the furnace body 9.

[0024] The heat absorption mechanism includes a conduit, a negative pressure fan 10, a hydraulic rod 2 and an air pipe 1. The hydraulic rod 2 is fixedly arranged on the furnace body 9. Two hydraulic rods 2 are arranged on the furnace body 9. The hydraulic rod 2 is fixedly connected to the fixing plate 7. The conduit is detachably arranged on the fixing plate 7. The conduit is divided into a guide part 5 and a straight tube part 4. The straight tube part 4 is fixedly arranged on the guide part 5.

[0025] The guide part 5 is fixedly connected to the mounting plate 11, and the mounting plate 11 has a fixing hole. The fixing hole is threadedly connected to a threaded rod 12, and the threaded rod 12 is threadedly connected to the fixing plate 7. The threaded rod 12 allows the conduit to be detachably set on the fixing plate 7, which is convenient for maintenance of the conduit.

[0026] A connecting pipe 3 is fixedly connected to the straight portion 4, a negative pressure blower 10 is disposed in the connecting pipe 3, and an air pipe 1 is fixedly connected to the end of the connecting pipe 3 away from the straight portion 4. The negative pressure blower 10 is located between the air guide portion 5 and the connecting pipe 3. When the furnace door 8 is opened to remove the workpiece in the furnace body 9, the negative pressure blower 10 is first started. The negative pressure blower 10 generates negative pressure wind force, and the outside air is sucked into the air guide portion 5, and then passes through the negative pressure blower 10, the connecting pipe 3, and the air pipe 1 in sequence. At this time, the furnace door 8 is opened again, and the hot air escaping from the furnace body 9 is sucked into the air guide portion 5 by the negative pressure blower 10. When the staff member stands on the side of the furnace body 9 away from the air pipe to perform work, it is less likely to be burned by the hot air escaping from the furnace body 9.

[0027] One end of the guide portion 5 away from the straight tube portion 4 is fixedly connected to a guide plate 6. Two guide plates 6 are provided on the guide portion 5. The two guide plates 6 are respectively provided on both sides of the guide portion 5. The guide plates 6 can make the hot air in the air be sucked into the guide portion 5 more concentratedly.

[0028] The conduit is tilted on the furnace body 9. When a worker stands on one side of the furnace body 9 to work, the conduit is tilted, which can better absorb the hot air escaping from the furnace body 9 and reduce the impact of the hot air on the worker.

[0029] A dust filter 13 is installed on the side of the guide part 5 away from the straight tube part 4. The dust filter 13 plays a role in dust prevention. When the negative pressure fan 10 generates negative pressure wind to suck the hot air into the guide part 5, it will also suck the dust in the air into the guide part 5. The dust will eventually accumulate on the negative pressure fan 10. When the negative pressure fan 10 accumulates a lot of dust, it will affect the effect of the negative pressure fan 10. The dust filter 13 can filter the dust of the hot air entering the guide part 5 and reduce the dust accumulation on the negative pressure fan 10.

[0030] The implementation principle of this embodiment is as follows: when the workpiece in the furnace body 9 is to be taken out, the negative pressure fan 10 is first started, and the negative pressure fan 10 generates negative pressure wind force, which sucks air into the guide part 5 of the conduit. The air then passes through the negative pressure fan 10, the connecting pipe 3 and the air pipe 1 in sequence. At this time, when the furnace door 8 is opened, hot air escapes from the furnace body 9. Due to the negative pressure wind force generated by the negative pressure fan 10, the hot air escapes from the furnace body 9 and is sucked into the guide part 5 by the negative pressure fan 10. Then the hydraulic rod 2 is started to adjust the distance between the conduit and the furnace body 9 so that the conduit can better absorb the hot air escaping from the furnace body 9. At this time, the staff stands on the side of the furnace body 9 away from the conduit to perform the operation, and the staff is not easily scalded by the hot air, thereby achieving the effect of making the staff not easily scalded by the annealing furnace.
