Description

Technical Field

[0001] This utility model relates to the technical field of material degreasing equipment, specifically to a degreasing device for porous metal material films. Background Technology

[0002] In the fabrication process of porous metallic thin films, degreasing is a crucial step in removing organic matter or impurities from the material's interior, and its effectiveness directly affects the uniformity of the pore structure and the mechanical properties of the final product. Traditional degreasing processes mainly rely on sintering furnaces in a vacuum or protective atmosphere environment, where high-temperature heating causes the volatilization and decomposition of organic matter such as grease in the material.

[0003] The equipment suffers from high pollution and maintenance costs. During the high-temperature degreasing process, a large amount of volatile grease tends to adhere to the inner wall of the sintering furnace or enter the working pump body through the vacuum system. Long-term accumulation can lead to internal contamination of the furnace, requiring frequent shutdowns for cleaning. Furthermore, grease entering the vacuum pump may cause problems such as pump oil emulsification and aging of seals, significantly increasing the frequency and cost of equipment maintenance.

[0004] The contradiction between energy consumption and production efficiency is prominent. As a high-power heating device, the sintering furnace takes a long time to heat up and down (usually several hours), resulting in a longer production cycle per batch and high energy consumption. In addition, high-temperature degreasing requires precise control of the heating rate to avoid material cracking, which further limits the potential for improving production efficiency. Utility Model Content

[0005] In view of this, the present invention provides a degreasing device for porous metal film. The present invention avoids the need for frequent equipment maintenance by using steam degreasing, thereby indirectly increasing the degreasing efficiency.

[0006] To solve the above-mentioned technical problems, this utility model provides a degreasing device for porous metal material films, including a tank with an internal cavity for containing materials. The materials can be placed in the cavity for degreasing processing. The cavity has an inverted T-shaped structure, and the T-shaped structure forms a material collection platform with an annular structure.

[0007] The lid is used to seal the can.

[0008] A heating element, located at the bottom of the inner wall of the tank, is used to heat the internal cavity of the tank, thereby heating the liquid water inside the tank into water vapor.

[0009] The cooling component, located at the top of the inner wall of the tank, is used to cool the internal cavity at the top of the tank. The cooling component can condense water vapor into liquid water.

[0010] The material rack has several connecting rods connected to it. The connecting rods are connected to the bottom of the can lid, and the material rack is fixed to the bottom of the can lid through the connecting rods.

[0011] The collection tank, which is arranged in a ring on the collection platform, is used to collect condensed liquid water.

[0012] The collection pipe is fixed to the tank body, and the end of the collection pipe is connected to the bottom of the collection tank.

[0013] The end of the collection tank has a V-shaped structure, meaning that the V-shaped structure has an opening that faces the tank lid. The V-shaped structure has two inclined annular surfaces, the tops of which are connected to the inner and outer edges of the collection platform, which facilitates the collection of condensed liquid water and prevents the condensed liquid water from dripping down to the bottom of the tank cavity.

[0014] The collection tank has a right-angled trapezoidal cross-section, and the end of the collection pipe is connected to the lowest point of the horizontal line of the collection tank, so that the mixed liquid in the collection tank can be gathered at the end of the collection pipe.

[0015] The end of the collection pipe furthest from the tank is also connected to an oil-water separation mechanism, which can separate the oil and water in the mixture.

[0016] The oil-water separation mechanism includes a mixing tank connected to a collection pipe, which is used to store the mixed liquid. A corresponding oil storage tank is also provided for storing the separated oil. Both the mixing tank and the oil storage tank are equipped with discharge pipes. An overflow pipe is also horizontally connected between the mixing tank and the oil storage tank. The horizontal height of the overflow pipe is lower than that of the collection pipe, and the overflow pipe is used to guide the oil.

[0017] The mixing tank and the oil storage tank are each connected to an external observation tube. The observation tube has a concave structure and is made of transparent material, which makes it easy to observe the liquid level in the tank.

[0018] The can lid is also equipped with multiple threaded rods, which are vertically positioned on the outside of the can body. Each threaded rod has an ear plate on the can lid, which is fixed to the edge of the can lid. Each ear plate has a through hole vertically through it. The threaded rod is inserted into the through hole and slidably connected to the ear plate. A nut is also threaded onto the threaded rod, which is located below the ear plate on the threaded rod. The nut can indirectly support the can lid.

[0019] The heating and / or cooling components are fixed to the inner wall of the tank in a spiral structure.

[0020] The connecting rod is a pneumatic telescopic rod, which can drive the material rack to move up and down.

[0021] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0022] 1. Integrated design of steam degreasing and condensation recovery: Liquid water is converted into steam through a heating element, and the steam permeates the pores of a porous metal membrane to achieve efficient removal of organic matter; combined with a top cooling element, the steam is condensed back into liquid water, forming a closed-loop circulation system. This design avoids the problem of grease volatilization and equipment contamination caused by traditional high-temperature sintering, significantly reduces the frequency of furnace cleaning and vacuum pump maintenance costs, and extends the service life of the equipment.

[0023] 2. High-efficiency condensate collection and oil-water separation: The inverted T-shaped tank structure, combined with the annular collection platform and V-shaped collection trough design, uses the inclined annular surface to guide the condensate to converge into the trough, preventing droplets from dripping directly to the bottom of the tank and causing secondary pollution. The collection trough has a right-angled trapezoidal cross-section and is connected to the lowest end of the collection pipe, ensuring complete discharge of the mixture. Combined with the overflow-type oil-water separation mechanism (mixing tank, oil storage tank, and overflow pipe), automatic stratification and separation of oil and water are achieved. The recovered oil can be centrally processed, reducing environmental pollution.

[0024] 3. Optimized heating and cooling efficiency: The heating and cooling components adopt a spiral structure attached to the inner wall of the tank, increasing the heat exchange area and improving the heating and cooling rates. Compared with the heating and cooling cycle of several hours in traditional sintering furnaces, this device can shorten the processing time per batch, significantly reduce energy consumption, and avoid the risk of material cracking due to slow heating.

[0025] 4. Improved ease of operation and safety: The tank lid is connected to the material rack via a pneumatic telescopic rod, enabling automated lifting and reducing manual operation intensity; the transparent observation tube monitors the liquid level of the mixing tank and the oil storage tank in real time, avoiding the risk of overflow and improving process stability.

[0026] 5. Reduced overall costs and improved product performance: The closed-loop steam system reduces water waste, and the oil-water separation mechanism lowers wastewater treatment costs. There are no high-temperature oxidation side reactions during degreasing, the porous metal film exhibits improved pore structure uniformity, and its mechanical properties are significantly optimized, meeting the demands of high-end applications.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-2 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0035] This invention provides a degreasing device for porous metal film, such as... Figure 1 , 2 As shown: It includes a cylindrical tank 100, with a cavity inside the tank 100 for receiving materials. The tank 100 contains a water source, and a heating element 102 is provided at the bottom of the inner wall of the tank 100 corresponding to the water source. The heating element 102 can be a spiral heating coil. The water source should cover the heating element 102, so that when the heating element 102 is working, it can heat the water to form water vapor.

[0036] The tank body 100 is also equipped with a tank cover 400 for sealing the tank body 100. The bottom of the tank cover 400 is provided with a material rack 202 via a connecting rod 201. The material rack 202 is used to place materials. The connecting rod 201 is made of a pneumatic push rod or a pneumatic telescopic rod, which makes it easy to pick up and put down the materials on the material rack 202.

[0037] The top of the inner wall of the tank 100 is also equipped with a cooling element 103, which can be a spiral condenser tube. The cooling element 103 cools the water vapor, allowing the condensed liquid to adhere to the inner wall of the tank 100. The cavity inside the tank 100 has an inverted T-shaped structure, forming an annular collecting platform 101. The liquid on the inner wall of the tank 100 flows onto the collecting platform 101. The tank is also equipped with an annular collection trough 104, which is connected to the upper surface of the collection platform 101. This allows the liquid on the collection platform 101 to enter the collection trough 104, thus preventing the liquid from dripping from the collection platform 101 to the bottom of the tank 100. The tank 100 is also equipped with a horizontal collection pipe 300, the end of which is connected to the bottom of the collection trough 104. This allows the liquid in the collection trough 104 to be discharged from the tank 100 through the collection pipe 300.

[0038] Specifically, the cross-section at the end of the collection tank 104 has a V-shaped structure, meaning that the V-shaped structure has an opening, such as... Figure 2 As shown: the opening is oriented towards the tank cover 400 and also forms two inclined annular surfaces. The tops of the two inclined annular surfaces are connected to the inner and outer edges of the collection platform 101, that is, the liquid hopper falling on the collection platform 101 can enter the collection tank 104, thereby further preventing the liquid from dripping from the collection platform 101 to the bottom of the inner cavity of the tank 100.

[0039] Furthermore, the bottom of the collection tank 104 has an arc-shaped structure, that is, the cross-section of the annular collection tank 104 is a right-angled trapezoidal structure. The bottom of the collection tank 104 is inclined, and the end of the collection pipe 300 is connected to the lowest point of the horizontal line of the collection tank 104. In this way, the liquid can converge to the bottom in the collection tank 104 and then be discharged through the collection pipe 300, thereby preventing the liquid at the bottom of the collection tank 104 from failing to flow to the collection pipe 300.

[0040] Preferably, the end of the collection pipe 300 furthest from the tank 100 is also connected to an oil-water separation mechanism, such as... Figure 1 As shown: It includes a mixing tank 301 and an oil storage tank 302. The end of the collecting pipe 300 is connected to the mixing tank 301, so the liquid can enter the mixing tank 301 through the collecting pipe 300. Since the liquid contains water and oil, the oil will float to the top due to its density. The liquid can automatically separate into layers in the mixing tank 301. An overflow pipe 304 is also horizontally connected between the mixing tank 301 and the oil storage tank 302. The overflow pipe 304 is lower than the lowest level of the collecting pipe 300, so the oil on the upper layer will enter the oil storage tank 302 through the overflow pipe 304. The mixing tank 301 is also equipped with a discharge pipe 303, which can discharge the water in the lower layer of the mixing tank 301, thereby avoiding excessive water accumulation in the lower layer of the mixing tank 301. The oil storage tank 302 is also equipped with a discharge pipe 303, which facilitates the discharge of the separated oil.

[0041] Both the mixing tank 301 and the oil storage tank 302 are connected to observation tubes 305. The observation tubes 305 are vertically fixed to the tanks with a concave structure, so that the water level in the mixing tank 301 and the oil storage tank can be easily observed through the observation tubes 305.

[0042] It is worth mentioning that multiple threaded rods 401 are also vertically provided on the outer side of the tank body 100, such as... Figure 1As shown: Each threaded rod 401 is threadedly fitted with a nut 404. The nut 404 can be rotated to move on the threaded rod 401. Corresponding to the threaded rod 401, there are also ear plates 402 around the can lid 400. Each ear plate 402 has a vertical through hole 403. The diameter of the through hole 403 is larger than the diameter of the threaded rod 401, and the cross section of the through hole 403 is smaller than the cross section of the nut 404. That is, the can lid 400 can be placed on top of multiple nuts 404 through the ear plates 402, and rotating the nuts 404 can indirectly drive the can lid 400 to move up and down.

[0043] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0044] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
