Description

Technical Field

[0001] The utility model relates to the technical field of homogenizing furnaces, and specifically relates to a homogenization treatment device for aluminum profile production. Background Art

[0002] The homogenizing furnace is a special equipment for heat treatment after aluminum bar casting, aiming to eliminate the residual stress and non-uniformity of the metallographic structure generated during bar casting. It is an indispensable equipment for improving the quality of aluminum profile products. The homogenization treatment of aluminum bars and ingots includes three processes: heating, heat preservation, and cooling:

[0003] During the working process of the homogenizing furnace, aluminum bars and ingots are first placed in the furnace. Then, by controlling the heating elements in the furnace, the aluminum bars and ingots are heated to gradually increase their temperature until the required homogenization temperature is reached. The homogenization temperature is determined according to the type and specification of the aluminum bars and ingots. Different aluminum bars and ingots require different homogenization temperatures. After reaching the homogenization temperature, it is necessary to maintain a certain time to ensure that the internal structure and organization of the aluminum bars and ingots are uniformly improved;

[0004] During the heat preservation stage, the aluminum bars and ingots are maintained at the homogenization temperature to enable the grains inside them to grow and improve more uniformly. This process requires a certain amount of time to ensure the best improvement effect on the internal structure of the aluminum bars and ingots;

[0005] After the heat preservation stage ends, it is necessary to cool the aluminum bars and ingots. The purpose of cooling is to rapidly reduce the temperature of the aluminum bars and ingots to fix their internal organizational structure and make them have better performance and service life;

[0006] The working principle of the aluminum bar and ingot homogenizing furnace is to achieve the homogenization treatment of aluminum bars and ingots by controlling the heating power and time of the heating elements, as well as the control of the heat preservation and cooling processes. Through reasonable control and adjustment, the internal structure and performance of the aluminum bars and ingots can reach the best state.

[0007] After completing the homogenization heat preservation stage of aluminum bars and ingots, their cooling is generally transferred to another furnace dedicated to heat dissipation for cooling operations, so as to ensure the high-temperature environment inside this homogenizing furnace. During this process, when the furnace door of the homogenizing furnace is opened, the high-temperature air inside the homogenizing furnace will surge outwards. This not only causes a large amount of heat energy loss but also poses a certain safety hazard to the staff outside the furnace. Based on this, a homogenization treatment device for aluminum profile production is provided. Summary of the Utility Model

[0029] Please refer to Figures 1 to 3 , in the embodiment of the present utility model, a homogenization treatment device for aluminum profile production includes a homogenization furnace 1 composed of a furnace body 101, a furnace door 102, and a lifting mechanism 103. The furnace door 102 is vertically slidably installed at the front end of the furnace body 101.

When the furnace door 102 is opened, the hot air blocking component 2 is used to form an air curtain at the opening of the furnace body 101 to intercept the hot air inside the furnace body 101.

[0030] The hot air blocking component 2 includes a circulation unit and an air curtain unit.

[0031] The circulation unit is used to extract the hot air inside the furnace body 101 and blow it into the furnace body 101 from the opening of the furnace body 101 to realize the circulating flow of the hot air inside the furnace body 101, thereby avoiding the outward flow of the hot air inside the furnace body 101.

[0032] The air curtain unit is used to form an air curtain at the opening of the furnace body 101 through normal temperature air to separate the hot air inside the furnace body 101 from external staff.

[0033] The circulation unit includes a suction pipe 201, a circulation fan 202, a first connecting pipe 203, a first n-shaped communicating pipe 204, and a reflux nozzle 205.

[0034] The suction pipe 201, the circulation fan 202, and the first connecting pipe 203 are distributed on one side outside the furnace body 101, and the circulation fan 202 is fixed to the furnace body 101 through a fixed bracket. One end of the suction pipe 201 extends to the inner end of the furnace body 101, and the other end of the suction pipe 201 is fixedly connected to the input end of the circulation fan 202. One end of the first connecting pipe 203 is connected to the output end of the circulation fan 202.

[0035] The first n-shaped communicating pipe 204 is distributed on both sides of the outer wall of the furnace body 101 and extends to the inside of the furnace body 101. The first n-shaped communicating pipe 204 is close to the opening end of the furnace body 101, and the other end of the first connecting pipe 203 is connected and communicated with the first n-shaped communicating pipe 204.

[0036] The reflux spray head 205 is fixed inside the first n-type connecting pipe 204 and is in communication with the inner cavity of the first n-type connecting pipe 204. The hot air blown out by the reflux spray head 205 flows towards the tail end of the furnace body 101;

[0037] The air curtain unit includes a high-pressure air pump 206, a second connecting pipe 207, a second n-type connecting pipe 208, and a square spray head 209;

[0038] The second n-type connecting pipe 208 is distributed on both sides of the outer wall of the furnace body 101 and extends to the inside of the furnace body 101. The second n-type connecting pipe 208 is located at one end of the first n-type connecting pipe 204 away from the tail end of the furnace body 101. The square spray head 209 is fixed inside the second n-type connecting pipe 208 and extends to the inside of the furnace body 101. The high-speed air flow blown out by the square spray head 209 forms an air curtain effect;

[0039] The high-pressure air pump 206 is distributed on one side outside the furnace body 101. Both ends of the second connecting pipe 207 are respectively connected to the output end of the high-pressure air pump 206 and the second n-type connecting pipe 208. The operation of the high-pressure air pump 206 is used to transport high-pressure air flow to the second n-type connecting pipe 208;

[0040] The numbers of the reflux spray head 205 and the square spray head 209 are both set to be multiple. The reflux spray head 205 and the square spray head 209 are respectively evenly distributed along the trajectories of the first n-type connecting pipe 204 and the second n-type connecting pipe 208.

[0041] In this embodiment: A heating unit for uniformly heating aluminum bars and aluminum ingots is provided inside the furnace body 101. After the aluminum bars and aluminum ingots are sent into the furnace body 101 through an external vehicle frame, the furnace door 102 is lowered by the lifting mechanism 103. The furnace door 102 seals the opening end of the furnace body 101. Then, the heating unit operates to perform a heating and homogenization operation on the aluminum bars and aluminum ingots. When the homogenization and heat preservation stage of the aluminum bars and aluminum ingots is completed, the furnace door 102 is opened by the lifting mechanism 103;

[0042] Meanwhile, the circulation fan 202 and the high-pressure air pump 206 are synchronously started. Among them, the circulation fan 202 generates suction on the suction pipe 201. This suction sucks the tail end of the furnace body 101 through the suction pipe 201. The hot air at the tail of the furnace body 101 enters the inside of the first n-type connecting pipe 204 through the suction pipe 201, the circulation fan 202, and the first connecting pipe 203, and is ejected through the reflux spray head 205. Due to the suction of the air at the tail end of the furnace body 101 by the suction pipe 201, a negative pressure is generated at the tail end of the furnace body 101. Therefore, the air at the front end of the furnace body 101 will flow towards the tail end of the furnace body 101. The air flow ejected by the reflux spray head 205 is combined to make the hot air inside the furnace body 101 circulate between the tail end of the furnace body 101 and the reflux spray head 205. The hot air in such a flowing state can reduce the outward flow of the hot air inside the furnace body 101;

[0043] The high-pressure air pump 206 can generate high-pressure air flow and deliver it to the inside of the second n-type connecting pipe 207 through the second connecting pipe 207, and then spray it out through the square spray head 209. The high-speed ejected air flow forms an air curtain effect at the outer end of the return spray head 205, so as to form a separation effect between the hot air in the furnace body 101 and the external environment. In this way, it can effectively prevent the hot air from escaping and causing harm to the external staff. At the same time, compared with the traditional situation where hot air directly flows out, it can reduce the loss of heat energy, ensure the high-temperature environment inside the furnace body 101, and facilitate secondary use.

[0044] Please refer particularly to Figures 1 to 3 , the end of the return spray head 205 extends to the inner side of the furnace body 101 and is in an inclined state, and the inclined end of the return spray head 205 faces the tail end of the furnace body 101.

[0045] In this embodiment: through this structure, the air flow ejected from the return spray head 205 faces the tail end of the furnace body 101. Through the flow of this air flow, other hot air inside the furnace body 101 is driven to flow towards the tail end of the furnace body 101, achieving the effect of circulating flow of hot air.

[0046] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and should be covered within the protection scope of the present invention.
