Description

Technical Field

[0001] This application relates to the field of powder zinc diffusion degreasing technology, specifically to a degreasing device for powder zinc diffusion. Background Technology

[0002] Powder zinc diffusion is a process in which a workpiece is buried in a sealed container containing zinc powder and an inert medium (such as alumina), and heated to a certain temperature (usually 380-450℃). The zinc powder undergoes an atomic diffusion reaction with the iron matrix, forming a zinc-iron alloy diffusion layer on the workpiece surface. If oil contamination is present on the workpiece surface, it will form a protective film, like a "raincoat," separating the zinc powder from the workpiece matrix. This prevents the zinc powder from making sufficient contact with the matrix, hindering the zinc-iron atomic diffusion reaction and resulting in an uneven or substandard zinc diffusion layer.

[0003] Currently, when degreasing workpieces, the workpiece is usually placed in a container filled with degreasing solution, and then removed after a period of time. The oil stains on the surface of the workpiece are removed through a chemical reaction. For some workpieces with complex structures, tiny pores, or depressions, static degreasing methods cannot ensure that the degreasing solution fully penetrates these areas, which can easily lead to incomplete oil removal and a long degreasing time. Utility Model Content

[0004] In view of this, the purpose of this utility model is to overcome the shortcomings of the prior art and to propose an oil removal device for powder zinc diffusion, so as to solve the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides an oil removal device for powder zinc infiltration, including an oil removal cylinder. One end of the oil removal cylinder is fixedly connected to a liquid injection pipe. A drain valve is provided at the bottom end of the oil removal cylinder, and a waste liquid collection mechanism is provided at the drain valve. A flip-top mechanism is provided on the oil removal cylinder. A horizontal plate is fixedly connected to the inner wall of the oil removal cylinder. A through shaft is movably inserted through the inner side of the horizontal plate. An L-shaped plate is fixedly connected to the top of the through shaft. A frame is fixedly connected to the bottom of the L-shaped plate. A wire mesh is provided on the inner side of the frame. A dynamic circulation mechanism for driving the wire mesh to move up and down is provided on the oil removal cylinder.

[0006] Preferably, the waste liquid collection mechanism includes a pin fixedly connected to the outer surface of the drain valve, a hanger is attached to the pin, and a collection cylinder is rotatably connected to the bottom of the hanger. The waste liquid can be collected by the waste liquid collection mechanism and then disposed of in a unified manner after the collection is full.

[0007] Preferably, the flip-top mechanism includes a glass plate hinged to the degreasing cylinder, and the glass plate is provided with a handle. The workpiece can be placed into the wire mesh inside the frame at an appropriate time through the flip-top mechanism, and the degreasing process can be observed through the glass plate in the flip-top mechanism.

[0008] Preferably, the dynamic circulation mechanism includes a motor fixedly installed on the outer surface of the oil removal cylinder, and a drive gear is fixedly connected to the output end of the motor. The dynamic circulation mechanism enables the wire mesh near the surface of the oil removal liquid to move up and down repeatedly, "jumping out" and "diving in" the oil removal liquid.

[0009] Preferably, the inner side of the oil removal cylinder is rotatably connected to a rotating shaft, and a transmission gear is fixedly connected to one end of the rotating shaft near the drive gear, and the outer surface of the transmission gear meshes with the outer surface of the drive gear.

[0010] Preferably, the outer surface of the rotating shaft is provided with an eccentric wheel, the outer surface of the through shaft is movably sleeved with a spring, and the bottom of the through shaft is fixedly connected with a limiting piece.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This degreasing device for powder zinc diffusion uses an eccentric wheel to drive the frame and wire mesh to move dynamically longitudinally, causing the workpiece to "jump in and out" of the degreasing solution. When the workpiece jumps out of the degreasing solution, the degreasing solution adhering to the workpiece surface flows and is renewed under the action of gravity, surface tension and other factors, forming a "scouring" effect. This can deliver the degreasing solution to the tiny pores and depressions of the workpiece, ensuring that these hidden parts can also fully contact the degreasing solution, thereby effectively removing oil stains and improving the thoroughness of degreasing.

[0013] 2. This degreasing device for powder zinc diffusion can promptly remove solutions containing high concentrations of oil through the flow and renewal of the degreasing solution, replenishing it with fresh, highly active degreasing solution. This avoids the problem of local concentration imbalance, ensures that the degreasing reaction is always in a highly efficient state, and further shortens the degreasing time.

Detailed Implementation

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] Please see Figure 1-5 An oil removal device for zinc powder infiltration includes an oil removal cylinder 1, one end of which is fixedly connected to an injection pipe 2. A drain valve 3 is provided at the bottom of the oil removal cylinder 1, and a waste liquid collection mechanism is provided at the drain valve 3. A flip-top mechanism is provided on the oil removal cylinder 1. A horizontal plate 9 is fixedly connected to the inner wall of the oil removal cylinder 1. A through shaft 10 is movably inserted through the inner side of the horizontal plate 9. An L-shaped plate 11 is fixedly connected to the top of the through shaft 10. A frame 12 is fixedly connected to the bottom of the L-shaped plate 11. A wire mesh 13 is provided on the inner side of the frame 12. A dynamic circulation mechanism for driving the wire mesh 13 to move up and down is provided on the oil removal cylinder 1.

[0022] Through the above technical solution, the device needs to perform degreasing before powder zinc diffusion on the workpiece. First, the workpiece is placed on the wire mesh 13 inside the frame 12. Then, an appropriate amount of degreasing liquid is injected into the degreasing cylinder 1 through the injection pipe 2. The liquid level of the degreasing liquid is close to the wire mesh 13. With the help of the dynamic circulation mechanism, the workpiece on the wire mesh 13 can "jump" up and down. That is, the dynamic longitudinal movement of the wire mesh 13 makes the workpiece "jump in and out" of the degreasing liquid, which achieves the effect of dynamic degreasing. The impact force generated when the workpiece enters the degreasing liquid can break the adsorption balance between the oil and the workpiece surface. This dynamic impact makes it easier for the originally firmly attached oil to be peeled off from the workpiece surface, further enhancing the degreasing effect. Especially for some stubborn oil stains, the removal effect is more significant.

[0023] Specifically, the waste liquid collection mechanism includes a pin 4 fixedly connected to the outer surface of the drain valve 3, a hanger 5 hanging on the pin 4, and a collection cylinder 6 rotatably connected to the bottom of the hanger 5.

[0024] Through the above technical solution, the liquid collection cylinder 6 is responsible for collecting the generated waste liquid. After it is full, the hanger 5 can be removed from the hanging nail 4, and the liquid collection cylinder 6 can be removed for centralized treatment of the waste liquid.

[0025] Specifically, the flip-top mechanism includes a glass plate 7 hinged to the degreasing cylinder 1, and a handle 8 is provided on the glass plate 7.

[0026] Through the above technical solution, pulling the handle 8 can move the glass plate 7 to open or close it, while the glass plate 7 needs to be closed during the degreasing process, and the degreasing process in the degreasing cylinder 1 can be observed from the glass plate 7.

[0027] Specifically, the dynamic circulation mechanism includes a motor 14 fixedly installed on the outer surface of the oil removal cylinder 1, and a drive gear 15 is fixedly connected to the output end of the motor 14.

[0028] Through the above technical solution, after the motor 14 is turned on, it can drive the drive gear 15 to rotate, which in turn drives the transmission gear 17 to rotate, and finally drives the rotating shaft 16 to rotate synchronously.

[0029] Specifically, a rotating shaft 16 is rotatably connected to the inner side of the oil removal cylinder 1, and a transmission gear 17 is fixedly connected to one end of the rotating shaft 16 near the drive gear 15, and the outer surface of the transmission gear 17 meshes with the outer surface of the drive gear 15.

[0030] Through the above technical solution, during the rotation of the rotating shaft 16, the two sets of eccentric wheels 18 on its surface will make circular motion and gradually approach until they completely contact the L-shaped plate 11. During this period, the L-shaped plate 11 will be pushed down by one end. When the tip of the eccentric wheel 18 moves away from the L-shaped plate 11, the L-shaped plate 11 will be pushed upward again under the elastic reset action of the spring 19.

[0031] Specifically, an eccentric wheel 18 is provided on the outer surface of the rotating shaft 16, a spring 19 is movably sleeved on the outer surface of the through shaft 10, and a limit plate 20 is fixedly connected to the bottom of the through shaft 10.

[0032] Through the above technical solution, during the rotation of the eccentric wheel 18, the L-shaped plate 11 will first move down and then up. The entire frame 12 and wire mesh 13 will gradually move down and then up. The through shaft 10 and the L-shaped plate 11 will move synchronously. The function of the limiting piece 20 is to relatively limit the through shaft 10 and prevent it from detaching from the horizontal plate 9.

[0033] Working Principle: Before powder zinc infiltration, this device requires degreasing of the workpiece. First, the workpiece is placed on the wire mesh 13 inside the frame 12. Then, the handle 8 is held and the glass plate 7 is moved to cover the degreasing cylinder 1, ensuring a relatively closed state throughout the degreasing process to reduce splashing of oil and other waste liquids. Afterward, an appropriate amount of degreasing liquid is injected into the degreasing cylinder 1 through the injection pipe 2, with the liquid level close to the bottom of the wire mesh 13. During degreasing, the motor 14 is turned on to drive the drive gear 15 to rotate. The moving gear 15 will rotate in conjunction with the transmission gear 17, which in turn will drive the rotating shaft 16 to rotate synchronously. During this process, the two sets of eccentric wheels 18 on the rotating shaft 16 will perform circular motion, and the outer circumference of the eccentric wheels 18 will always be in contact with the top of the L-shaped plate 11 under the action of the spring 19. As the tip of the eccentric wheel 18 gradually approaches the L-shaped plate 11, the L-shaped plate 11 is pushed and gradually moves downward. During this process, the through shaft 10 will pass through the horizontal plate 9 and move synchronously with the L-shaped plate 11, and the spring 19 will be gradually compressed. The frame 1 at the bottom of the L-shaped plate 11... 2. The wire mesh 13 will move down synchronously, and the workpiece placed on the wire mesh 13 will pass through the surface of the degreasing liquid and enter the degreasing liquid during the downward movement. When the eccentric wheel 18 rotates to the point where its tip gradually moves away from the L-shaped plate 11, under the elastic reset action of the spring 19, the L-shaped plate 11 will be pushed upward and always in contact with the outer periphery of the eccentric wheel 18. During this period, the L-shaped plate 11 will lift the frame 12 and the wire mesh 13, thereby allowing the workpiece on the wire mesh 13 to "jump out" of the degreasing liquid. This dynamic longitudinal movement back and forth in the degreasing liquid During the process, the workpiece will repeatedly "jump in and out" at the surface of the degreasing solution. When the workpiece jumps out of the degreasing solution, the degreasing solution adhering to the workpiece surface will flow and be renewed under the influence of gravity, surface tension, and other factors. New degreasing solution can quickly replenish the workpiece surface, fully contacting the oil and accelerating the chemical reaction. At the same time, the impact force generated when the workpiece enters the degreasing solution helps to break the adsorption balance between the oil and the workpiece surface, promoting the peeling off of the oil and greatly improving the degreasing efficiency and shortening the degreasing time. After the degreasing is completed, the drain valve 3 can be opened to allow the waste liquid in the degreasing cylinder 1 to be collected by the collection cylinder 6 for subsequent unified treatment.
