Description

Technical Field

[0001] This utility model relates to the field of powder metallurgy sintering furnace technology, specifically a powder metallurgy sintering furnace with waste gas purification function. Background Technology

[0002] A powder metallurgy sintering furnace is a piece of equipment used in powder metallurgy processes. It is mainly used to sinter metal powder or other material powders into dense solid materials by heating. This process is usually carried out under certain temperature and pressure, allowing the powder particles to adhere to each other and finally form the desired metal or alloy material. Powder metallurgy sintering furnaces generate waste gas during the sintering process. These waste gases typically include harmful gases, particulate matter, and volatile organic compounds. After a period of use, the filter element of the waste gas purification mechanism of the powder metallurgy sintering furnace needs to be replaced.

[0003] The existing technology for exhaust gas purification mechanisms in powder metallurgy sintering furnaces is cumbersome to replace with filter elements, and filter element replacement can only be performed when the powder metallurgy sintering furnace is not in operation. Replacing the filter element while the powder metallurgy sintering furnace is running will result in poor exhaust gas emission from the powder metallurgy sintering furnace, and the toxic exhaust gas in the powder metallurgy sintering furnace will come into contact with workers, which will cause harm to the workers.

[0004] Therefore, those skilled in the art have provided a powder metallurgy sintering furnace with exhaust gas purification function to solve the problems mentioned in the background art. Utility Model Content

A filter element installation mechanism is provided on the inner side of each set of exhaust gas purification shells.

The filter element installation mechanism is used to push the exhaust gas purification filter element out of the furnace, and the sealing mechanism is used to seal the connection points between the exhaust gas purification shells and the exhaust gas exhaust pipes on both sides.

[0010] As a further improvement of this utility model: both inner side walls of the exhaust gas purification housing are fixedly connected to limiting units, which are used to limit the positioning of the fixing block and the sealing block.

[0011] As a further embodiment of this utility model: the limiting unit includes a sealing block base, a limiting block, a fixing plate, and a sealing groove.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1 and2 As shown, this utility model embodiment provides a powder metallurgy sintering furnace with exhaust gas purification function, including a powder metallurgy sintering furnace body 1, an exhaust gas purification shell 3, an exhaust gas purification filter element 73, a filter element installation mechanism 7, and a sealing mechanism 8. Exhaust gas exhaust pipes 2 are fixedly connected to both sides of the two sets of exhaust gas purification shells 3. One side of the exhaust gas exhaust pipe 2 of each set of exhaust gas purification shells 3 is fixedly connected to the input end of a fan 5. The fan 5 is located on the upper side of the powder metallurgy sintering furnace body 1. The other side of the exhaust gas exhaust pipes 2 of each set of exhaust gas purification shells 3 is fixedly connected to the inner cavity of the powder metallurgy sintering furnace body 1. A filter element installation mechanism 7 is provided on the inner side of each set of exhaust gas purification shells 3. A sealing mechanism 8 is provided on the side walls of the two sets of filter element installation mechanisms 7 and the exhaust gas purification shells 3. The filter element installation mechanism 7 is used to push the exhaust gas purification filter element 73 out of the furnace, and the sealing mechanism 8 is used to seal the connection points between the exhaust gas purification shells 3 and the exhaust gas exhaust pipes 2.

[0025] In this embodiment, the exhaust gas in the powder metallurgy sintering furnace body 1 is drawn out and discharged by the blower 5 through the exhaust pipe 2. The exhaust gas passes through the exhaust pipe 2 and exits from the two exhaust gas purification shells 3. Two sets of exhaust gas purification filter elements 73 filter the incoming exhaust gas. When the powder metallurgy sintering furnace body 1 is running and the exhaust gas purification filter element 73 is being replaced, the sealing door on one side of the exhaust gas purification shell 3 is opened. At the same time, the filter element installation mechanism 7 automatically pushes out the exhaust gas purification filter element 73. Simultaneously, the filter element installation mechanism 7 drives the sealing mechanism 8 to seal the connection between the two sides of the exhaust gas purification shell 3 and the exhaust pipe 2, so that the exhaust gas passes through the other exhaust gas purification shell 3. The connection between the two sides of the replaced exhaust gas purification shell 3 and the exhaust pipe 2 is sealed, which will not affect the normal exhaust of the powder metallurgy sintering furnace body 1, and at the same time, prevents the staff from coming into contact with the exhaust gas.

[0026] like Figure 2 As shown, optionally, the filter element installation mechanism 7 includes a slider 71, a damping spring 72, and an exhaust gas purification filter element 73. The inner sides of both sets of exhaust gas purification housings 3 are slidably connected to the slider 71. The damping spring 72 is fixedly connected between the two sets of sliders 71 and one side wall of the two sets of exhaust gas purification housings 3. The exhaust gas purification filter element 73 is slidably placed inside the exhaust gas purification housing 3. The exhaust gas purification filter element 73 and the slider 71 cooperate with each other.

[0027] In this embodiment, when the sealed movable door on one side of the exhaust gas purification housing 3 is opened, the damping spring 72 releases its elastic force from the compressed state. The damping spring 72 drives the slider 71 to slide outward, and the slider 71 pushes the exhaust gas purification filter element 73 to be discharged from the inside of the exhaust gas purification housing 3, making it convenient for the staff to pick up the material.

[0028] like Figure 2 and 3As shown, optionally, the closing mechanism 8 includes a fixing block 81, a sealing block 82, a spring 83, and a limiting unit. The fixing blocks 81 are fixedly connected to both sides of one end of a set of sliders 71. A sliding groove is opened on one side of each of the two sets of fixing blocks 81. The sealing blocks 82 are slidably connected to the inner sides of the two sets of sliding grooves. Multiple sets of springs 83 are fixedly connected between the two sets of sealing blocks 82 and the two sets of sliding grooves. The limiting unit is used to limit the fixing blocks 81 and the sealing blocks 82.

[0029] In this embodiment, when the slider 71 slides outward, it drives the fixed blocks 81 on both sides to move towards the limiting unit. The fixed blocks 81 drive the sealing block 82 into the limiting unit for limiting. The spring 83 makes the sealing block 82 and the limiting unit fit tightly together. The surface of the sealing block 82 has sealing rubber, and the sealing block 82 is inclined.

[0030] like Figure 3 As shown, optionally, limiting units are fixedly connected to both inner side walls of the exhaust gas purification housing 3, and the limiting units are used to limit the fixing block 81 and the sealing block 82.

[0031] In this embodiment, the limiting unit limits the fixing block 81 and the sealing block 82 to prevent the fixing block 81 and the sealing block 82 from shifting.

[0032] like Figure 3 As shown, optionally, the limiting unit includes a sealing block base 84, a limiting block 85, a fixing plate 86, and a sealing groove 87. The inner side walls of one set of the exhaust gas purification housing 3 are fixedly connected to the sealing block base 84. The limiting block 85 is fixedly connected to one side of both sets of the sealing block base 84. The fixing plate 86 is fixedly connected to the other side of both sets of the sealing block base 84. The inner side of both sets of the sealing block base 84 is provided with a sealing groove 87. The sealing groove 87 and the sealing block 82 cooperate with each other.

[0033] In this embodiment, when the sealing block 82 slides into the sealing groove 87, the limiting block 85 guides the fixing block 81. When the sealing block 82 slides out of the sealing groove 87, the fixing plate 86 guides the sealing block 82 to slide out of the sealing groove 87.

[0034] like Figure 1 As shown, optionally, a heat dissipation mechanism 6 is fixedly connected to one side of the upper end of the powder metallurgy sintering furnace body 1, and the exhaust pipe 2 is fixedly connected to the heat dissipation mechanism 6 through it. The heat dissipation mechanism 6 is used to dissipate heat from the exhaust pipe 2.

[0035] In this embodiment, the heat dissipation mechanism 6 cools and dissipates the high-temperature gas discharged from the main body 1 of the powder metallurgy sintering furnace, so as to prevent other parts from having their service life reduced due to high temperature.

[0036] like Figure 4As shown, optionally, the heat dissipation mechanism 6 includes a heat dissipation box 61, heat dissipation fins 62 and a fan module 63. The heat dissipation box 61 is fixedly connected to one side of the upper end of the powder metallurgy sintering furnace body 1. The heat dissipation fins 62 are fixedly connected to both ends of the heat dissipation box 61, and the fan module 63 is fixedly connected to both ends of the heat dissipation box 61.

[0037] In this embodiment, when the exhaust gas passes through the heat dissipation box 61 in the exhaust gas pipe 2, the heat dissipation fins 62 on both sides of the heat dissipation box 61 absorb heat from the exhaust gas in the exhaust gas pipe 2, thereby cooling the exhaust gas, and the fan module 63 dissipates heat from the heat dissipation fins 62.

[0038] like Figure 2 As shown, optionally, the outer layer of the exhaust gas purification filter element 73 is made of polyester fiber material, the middle layer is made of honeycomb activated carbon material, and the inner layer is made of glass fiber material.

[0039] In this embodiment, the polyester fiber material of the exhaust gas purification filter element 73 can effectively intercept larger particles in the air, activated carbon has excellent adsorption properties and can adsorb toxic and harmful gases in the exhaust gas, and glass fiber has excellent filtration capabilities and can capture small particles in the air.

[0040] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0041] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
