Description

Technical Field

[0001] This invention relates to the field of zinc powder production technology, and in particular to a production equipment and method for zinc powder used in zinc diffusion processes. Background Technology

[0002] The principle of powder zinc diffusion technology is to place the zinc diffusion agent and the steel part in a zinc diffusion furnace and heat it to about 400°C. The active zinc atoms penetrate into the steel part from the surface to the interior. At the same time, iron atoms diffuse from the inside out, which forms a zinc-iron intermetallic compound on the surface of the steel part, namely a zinc coating. The main raw material for zinc diffusion is zinc powder.

[0003] Currently, when producing zinc powder using the distillation method, the zinc vapor needs to be cooled to form zinc powder. However, there are still some shortcomings in the current cooling process for zinc powder:

[0004] 1. When cooling zinc vapor, zinc is highly reactive and easily oxidized by oxygen in the air during the formation of zinc powder, which can lead to quality problems in the produced zinc powder.

[0005] 2. Furthermore, after the zinc powder is cooled, it cannot be screened according to the size of the zinc powder particles, which means that screening is still required during subsequent packaging, making the production process more complicated.

[0006] To address the above problems, this invention proposes a production equipment and method for zinc powder used in the zinc diffusion process. Summary of the Invention

[0017] In one possible design, the ventilation assembly further includes two stirring racks symmetrically slidably connected within the heat exchange box.

[0018] In one possible design, the cooling mechanism includes an annular box fixedly fitted onto a base box. A water pump is fixedly installed on one side of the top of the annular box, with the suction end of the water pump extending into the annular box. A connecting pipe is fixedly installed on the outlet end of the water pump, with the top end of the connecting pipe extending into the inlet pipe and engaging with the inner wall of the inlet pipe. A connecting pipe is fixedly installed on the inner wall of the other side of the top of the annular box, with the top end of the connecting pipe extending above the annular box and engaging with the outlet pipe. A cooling pipe is fixedly installed inside the annular box, with both ends of the cooling pipe extending to the outside of the annular box. One end of the cooling pipe is used to connect to an external refrigerant mechanism, and the other end of the cooling pipe is fitted with a sealing assembly.

[0019] In one possible design, the sealing assembly includes a mounting base fixedly installed on the other end of the cooling pipe.

A second compression spring is sleeved on the support rod, and the two ends of the second compression spring are fixedly connected to the other end of the support rod and one side of the support plate, respectively.

[0020] In one possible design, the vibration mechanism includes a transmission gear ring rotatably connected to the inner wall of the bottom of the base box. A mounting plate is fixedly installed inside the transmission gear ring. A nut is fixedly installed on the top of the mounting plate. A reciprocating screw is threaded through the nut. The bottom end of the reciprocating screw passes through the mounting hole and extends to the bottom of the base box. A limit plate is fixedly installed on the bottom end of the reciprocating screw.

[0021] A connecting groove is provided at the top of the reciprocating screw, and a push rod is slidably connected in the connecting groove. The top of the push rod extends above the reciprocating screw and a hammer head is fixedly installed thereon. The hammer head is used to strike the rotating box, causing the rotating box to vibrate. A first compression spring is fixedly installed at the bottom of the push rod, and the bottom of the first compression spring is fixedly connected to the bottom inner wall of the connecting groove.

[0022] A production method, applied in the production equipment for zinc powder in the zinc diffusion process as described above, includes the following steps: S1, connection and flow control: connect the connector to an external zinc vapor delivery pipeline, rotate the rotating plate to drive the screw to rotate, and move the shroud longitudinally through the threaded pipe drive to adjust the communication area between the flow hole and the support pipe and control the zinc vapor flow rate.

[0023] S2. Zinc Vapor Cooling and Zinc Powder Formation: High-temperature zinc vapor is transported to the support tube, enters the moving shroud through the flow holes, and then enters the heat exchange box through the installation tube. The heat exchange box is immersed in water at a lower temperature, causing the zinc vapor to cool and form zinc powder.

[0024] S3. Cooling and Zinc Powder Collection: The water pump is started to draw water from the annular tank to the cooling tank to cool the zinc vapor. After the outlet pipe is connected to the connecting pipe, the water in the cooling tank is returned to the annular tank. The zinc powder formed during cooling falls into the rotating box and onto the second filter screen.

[0025] S4. Zinc Powder Screening and Packaging: The drive motor is started, driving the drive gear to rotate, which in turn drives the rotating box to rotate, providing centrifugal force for the zinc powder. The zinc powder undergoes multi-stage screening through the second and first filter tubes. The pore size of the first filter tube is smaller than that of the second filter tube, facilitating packaging.

[0026] S5. Zinc powder stirring and anti-adhesion: The conical column rotates with the rotating box, and the locking point and the locking groove engage to drive the rotating rod to rotate, which in turn drives the two stirring frames to perform a circular motion, stirring the cooled and solidified zinc powder and preventing the zinc powder from adhering to the heat exchange box.

[0027] S6. Cooling medium replacement: When replacing the cooling medium in the cooling pipe, the cooling medium is delivered into the cooling pipe, the increased air pressure pushes the spherical plate to separate from the mounting base, and the high-temperature gas is discharged to facilitate the replacement of the cooling medium.

[0028] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the invention.

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0030] In this invention, a separation mechanism is provided to drive the rotating box to rotate after the power assembly is started. At this time, the zinc powder that falls into the second filter tube will undergo centrifugal motion and pass through the second filter tube and the first filter tube in sequence. Since the pore size of the first filter tube is smaller than that of the second filter tube, multi-stage screening of zinc powder can be achieved, which facilitates the packaging of zinc powder.

[0031] This invention also includes a heat exchange mechanism. After connecting the ventilation assembly to an external zinc vapor delivery pipe, this mechanism can transport high-temperature zinc vapor into the ventilation assembly. Simultaneously, after connecting the water inlet pipe to the cooling mechanism, cooled water is delivered to the water inlet pipe and further to the cooling tank. Under the action of heat exchange, the zinc vapor is cooled and forms zinc powder. Afterwards, the water flows back to the cooling mechanism through the water outlet pipe, realizing water circulation and continuously cooling the zinc vapor.

[0032] Furthermore, this invention is equipped with a cooling mechanism that draws water from the annular tank and delivers it to the cooling tank via a water pump, thereby injecting cold water into the cooling tank to cool the zinc vapor. After the outlet pipe is connected to the connecting pipe, the water in the cooling tank can be returned to the annular tank. Simultaneously, connecting the cooling pipe to an external refrigerant system allows the refrigerant to be delivered to the cooling pipe to cool the water in the annular tank, maintaining it at a low temperature.

[0033] This invention also includes a vibration mechanism. When the connecting gear rotates with the output shaft of the drive motor, this mechanism meshes with a transmission gear ring, thereby driving the transmission gear ring and nut to rotate. As the nut rotates, the reciprocating screw undergoes longitudinal reciprocating motion through threaded transmission. When the reciprocating screw moves upward, the hammerhead strikes the rotating box, causing it to vibrate. This prevents zinc powder from getting stuck in the first and second filter screens during zinc powder screening. Simultaneously, the push rod is elastically supported by a first compression spring, ensuring that the impact force on the rotating box is not excessive during actual use, thus avoiding damage to the rotating box.

[0034] In summary, this invention allows the zinc powder or zinc vapor to be processed in a relatively enclosed environment during cooling to form zinc powder, thereby avoiding the oxidation of the produced zinc. Furthermore, after the zinc powder is produced, this invention can also sort the zinc powder, facilitating its classification and packaging, thus demonstrating good practicality.

[0046] The embodiments of the present invention will now be described with reference to the accompanying drawings.

[0047] In the description of the embodiments of the present invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "installation" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the devices are connected to each other and their relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of the present invention, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of the present invention.

[0048] Example 1

[0049] Reference Figures 1-10 This embodiment describes a zinc powder production equipment for a zinc diffusion process, comprising a base frame 1, a bottom box 2, electric push rods 3, a sealed box 4, and multiple functional mechanisms. The base frame 1 serves as the supporting structure for the entire equipment, with the bottom box 2 fixedly mounted on its top. Two electric push rods 3 are symmetrically mounted on the inner bottom wall of the bottom of the bottom box 2. The output axes of these two electric push rods 3 extend upwards, passing through the top of the bottom box 2, and are jointly and fixedly connected to a sealing ring 5. The sealing ring 5 fits tightly with the top of the bottom box 2 to ensure a tight seal. Simultaneously, the sealed box 4 is fixedly mounted on the top of the sealing ring 5, forming a closed working environment.

[0050] Separation Mechanism: Inside the base box 2, a rotating box 6 is installed, which is rotatably connected to the base box 2 via bearings and other rotating connecting parts. Inside the rotating box 6, a first filter screen 7 and a second filter screen 8 are fixedly installed from top to bottom, with the second filter screen 8 nested inside the first filter screen 7. This design allows the two to form filter layers with different pore sizes.

[0051] A power assembly is installed at the bottom of the rotating housing 6. This power assembly includes a rotating gear ring 12 fixedly mounted at the bottom of the rotating housing 6, and a drive motor 10 mounted on one side of the bottom of the base housing 2. The output shaft of the drive motor 10 passes through the side wall of the base housing 2 and is fixedly connected to a drive gear 11, which meshes with the rotating gear ring 12. When the drive motor 10 starts, the rotating housing 6 is driven to rotate through the meshing transmission between the drive gear 11 and the rotating gear ring 12.

[0052] The rotating chamber 6 causes the zinc powder falling into the second filter tube 8 to be subjected to centrifugal force, thereby achieving graded screening. Since the pore size of the first filter tube 7 is smaller than that of the second filter tube 8, the zinc powder will first undergo preliminary screening through the second filter tube 8, and then undergo more detailed screening through the first filter tube 7, achieving a multi-stage screening effect.

[0053] Vibration Mechanism: A mounting hole is made on the inner wall of the bottom of the base box 2, and a vibration mechanism is installed therein. The specific structure is not detailed, but it can be envisioned as an electromagnetic vibrator or a mechanical striking device. This vibration mechanism passes through the mounting hole and connects to the inner wall of the mounting hole. It is also connected to the power components in the separation mechanism, namely the drive motor 10 and the drive gear 11, to achieve synchronous or asynchronous vibration effects. The function of the vibration mechanism is to strike the rotating box 6 of the separation mechanism, helping to prevent zinc powder from clogging the filter screen and improving screening efficiency.

[0054] Heat exchange mechanism: The heat exchange mechanism is installed on the top inner wall of the enclosed box 4, with its top extending to the outside of the enclosed box 4 and its sides extending to the sides of the enclosed box 4 for easy connection to an external heat source or cold source. The bottom of the heat exchange mechanism extends into the interior of the second filter screen tube 8 and connects to the bottom of the rotating box 6. This heat exchange mechanism is used to heat or cool the zinc powder during the screening process to meet the temperature requirements of the zinc powder in the zinc diffusion process.

[0055] Cooling Mechanism: The cooling mechanism is designed as a structure mounted on the base box 2, connecting with the heat exchange mechanism to form a complete heat exchange system. The specific form of the cooling mechanism can be selected according to actual needs, such as a cooling water jacket or an air-cooled device, to dissipate the heat transferred by the heat exchange mechanism and ensure stable equipment operation.

[0056] Through the above specific implementation methods, the zinc powder production equipment for the zinc diffusion process can achieve efficient and multi-stage screening of zinc powder, and through the synergistic effect of the heat exchange mechanism and the cooling mechanism, meet the requirements of the zinc diffusion process for the temperature and quality of zinc powder.

[0057] Heat exchange mechanism: A cooling box 24 is fixedly installed on the inner wall of the top center of the enclosed box 4. The cooling box 24 is designed as a sealed structure, with an inlet pipe 44 fixedly installed on the inner wall of the top on one side and an outlet pipe 45 fixedly installed on the inner wall of the bottom on the other side. The inlet pipe 44 and the outlet pipe 45 extend to both sides of the enclosed box 4 and connect to the external cooling mechanism to form a cooling water circulation system.

[0058] The cooling tank 24 is used to hold cooling water. When high-temperature zinc vapor enters the closed tank 4 through the ventilation component, the cooling water in the cooling tank 24 cools the zinc vapor through heat exchange, causing it to condense into zinc powder. Subsequently, the warm water after heat exchange flows back to the cooling mechanism through the outlet pipe 45 for reuse.

[0059] Ventilation assembly: The core component of the ventilation assembly is an installation pipe 27 that penetrates the enclosed box 4 and is fixedly connected to its top inner wall. Inside the installation pipe 27 is a support pipe 28, the top end of which extends above the installation pipe 27 to facilitate connection to an external zinc vapor delivery pipeline.

[0060] A connector 29 is fixedly installed through one side of the inner wall of the support pipe 28. One end of the connector 29 extends to the outside of the support pipe 28 for connection to an external zinc vapor transmission pipeline.

[0061] An installation ring 31 is fixedly installed inside the support tube 28, and a movable cover 32 is slidably connected inside the installation ring 31. Flow holes 33 are provided on both inner walls of the movable cover 32 to control the flow rate of zinc vapor. A threaded tube 35 is fixedly installed on the top of the movable cover 32, and a screw 36 is threadedly connected inside the threaded tube 35. The top end of the screw 36 extends above the support tube 28 and is fixedly installed with a rotating plate 30. An annular groove 34 is provided at the bottom of the rotating plate 30, and the top end of the support tube 28 extends into the annular groove 34 and is slidably connected to the inner wall of the annular groove 34. By rotating the rotating plate 30, the screw 36 can be rotated inside the threaded tube 35, thereby driving the movable cover 32 to move up and down to adjust the communication area between the flow holes 33 and the support tube 28, thus controlling the flow rate of zinc vapor.

[0062] A heat exchange box 25 is fixedly installed at the bottom of the mounting pipe 27. The outer wall of the heat exchange box 25 is provided with multiple annular flanges 26 at equal intervals to increase the heat exchange area. When zinc vapor passes through the support pipe 28 and the movable cover 32, it enters the heat exchange box 25. Since the heat exchange box 25 is immersed in the cooling water of the cooling box 24, the zinc vapor is further cooled and condenses into zinc powder.

[0063] Inside the heat exchange box 25, two symmetrically sliding stirring racks 38 are connected and fixedly connected by the same rotating rod 37. The bottom end of the rotating rod 37 extends into the second filter screen tube 8 and connects to the bottom inner wall of the rotating box 6.

[0064] A conical column 9 is fixedly installed on the bottom inner wall of the rotating box 6. An adapter groove is provided at the top of the conical column 9, and two symmetrical slots are provided on the bottom inner wall of the adapter groove. The bottom end of the rotating rod 37 extends into the adapter groove and is fixedly installed with a chuck 39. Two locking points 40 are symmetrically fixedly installed on the bottom of the chuck 39. These two locking points 40 extend into their respective slots and are movably engaged with the slots.

[0065] When the rotating box 6 rotates under the drive of the power unit, the conical column 9 rotates accordingly. Due to the locking engagement between the locking point 40 and the locking slot, the rotation of the rotating box 6 drives the rotating rod 37 to rotate synchronously, thereby driving the two stirring racks 38 to perform circular motion within the heat exchange box 25. This stirring action helps prevent the cooled and solidified zinc powder from adhering to the inner wall of the heat exchange box 25, ensuring the smooth discharge and collection of the zinc powder.

[0066] Cooling mechanism: First, an annular box 41 is fixedly fitted onto the bottom box 2. A water pump 42 is fixedly installed on one side of the top of the annular box 41. Its suction end extends into the interior of the annular box 41 to draw cooling water, while its outlet end is connected to a connecting pipe 43. The top end of the connecting pipe 43 extends into the inlet pipe 44 and is engaged with its inner wall to ensure a sealed connection.

[0067] A connecting pipe 46 is fixedly installed on the inner wall of the other side of the top of the annular box 41. Its top end extends above the annular box 41 and is snapped into the outlet pipe 45 to form a return path for cooling water.

[0068] Cooling pipe installation: Cooling pipe 47 is fixedly installed inside the annular box 41, with both ends extending to the outside of the annular box 41. One end is used to connect to an external refrigerant system, and the other end is fitted with a sealing assembly.

[0069] A tubular mounting base 48 is fixedly installed at the other end of the cooling pipe 47, and a support plate 49 is fixed inside. A support rod 50 is slidably connected through the support plate 49, and a spherical plate 51 is fixedly installed at one end of the support rod 50, which fits tightly against the inner wall of the mounting base 48. A second compression spring 52 is sleeved on the support rod 50, and its two ends are fixedly connected to the other end of the support rod 50 and one side of the support plate 49, respectively, to provide stable elastic support.

[0070] Working principle: The water pump 42 is activated to extract water from the annular tank 41 and transport it to the cooling tank 24 to cool the zinc vapor. Subsequently, the water flows back to the annular tank 41 through the outlet pipe 45 and connecting pipe 46. Simultaneously, an external refrigerant system delivers refrigerant to the cooling pipe 47 to cool the water in the annular tank 41 and maintain its low temperature. When the refrigerant in the cooling pipe 47 needs to be replaced, the increased pressure due to the refrigerant input pushes the spherical plate 51 away from the mounting base 48, thereby expelling high-temperature gas and facilitating refrigerant replacement.

[0071] Vibration mechanism: A transmission gear ring 14 is rotatably connected to the bottom inner wall of the base box 2, and a mounting plate 15 is fixedly installed inside it. A nut 16 is fixedly installed on the top of the mounting plate 15, and a reciprocating screw 17 is threaded through the nut 16. The bottom end of the reciprocating screw 17 passes through the mounting hole and extends to the bottom of the base box 2, where a limiting plate 18 is fixedly installed. The two sides are slidably connected by limiting brackets 19 to ensure stability.

[0072] A connecting gear 13 is fixedly sleeved on the output shaft of the drive motor 10, meshing with the transmission gear ring 14. When the drive motor 10 is working, it drives the transmission gear ring 14 to rotate through the connecting gear 13, which in turn drives the nut 16 to rotate.

[0073] Because of the threaded connection between the nut 16 and the reciprocating screw 17, when the nut 16 rotates, it drives the reciprocating screw 17 to perform longitudinal reciprocating motion. A connecting groove 20 is formed at the top of the reciprocating screw 17, through which a push rod 21 is slidably connected. A hammer head 22 is fixedly installed at the top of the push rod 21 for striking the rotating box 6. A first compression spring 23 is installed at the bottom of the push rod 21 to provide elastic support.

[0074] When the reciprocating screw 17 moves upward, the hammer 22 strikes the rotating box 6, causing it to vibrate and thus preventing zinc powder from getting stuck on the first filter screen 7 and the second filter screen 8. Simultaneously, the elastic support of the first compression spring 23 prevents excessive striking force from damaging the rotating box 6. This vibration mechanism design improves the efficiency and effectiveness of zinc powder screening.

[0075] This invention proposes a production method for use in the production equipment of zinc powder for the above-mentioned zinc diffusion process, comprising the following steps:

[0076] S1. Connect the connector 29 to the external zinc vapor delivery pipeline, and drive the screw 36 to rotate by rotating the rotating plate 30. At this time, under the thread transmission action with the threaded pipe 35, the moving cover 32 can be driven to move longitudinally, thereby adjusting the communication area between the flow hole 33 and the support pipe 28, thereby controlling the flow rate of zinc vapor.

[0077] S2. Zinc vapor at high temperature is transported to the support tube 28, and then through two flow holes 33 it can be transported to the movable cover 32. After that, it can be transported to the heat exchange box 25 through the output of the installation tube 27. At this time, the heat exchange box 25 is immersed in water, so the temperature is low. When the zinc vapor is transported to the heat exchange box 25, it can be cooled down so that zinc powder can be formed.

[0078] S3. Start the water pump 42 to draw water out of the annular box 41 and then transport it to the cooling box 24. This allows cold water to be injected into the cooling box 24 to cool the zinc vapor, causing the zinc vapor to cool and form zinc powder. After the water outlet pipe 45 is connected to the connecting pipe 46, the water in the cooling box 24 can be transported back to the annular box 41. The zinc powder formed by cooling can fall into the rotating box 6 and fall within the range of the second filter screen pipe 8.

[0079] S4. Start the drive motor 10 to drive the drive gear 11 to rotate. At this time, under the meshing transmission action with the rotating gear ring 12, it can drive the rotating box 6 to rotate, so as to provide driving force for the rotating box 6. This allows the zinc powder to fall into the second filter tube 8 with centrifugal force, so that the zinc powder can pass through the second filter tube 8 and the first filter tube 7 respectively. The aperture of the first filter tube 7 is smaller than that of the second filter tube 8. Therefore, when screening zinc powder, multi-stage screening of zinc powder can be achieved for packaging.

[0080] S5. When the conical column 9 rotates with the rotating box 6, the rotating rod 37 can be driven to rotate by the locking point 40 and the locking slot. At this time, the two stirring racks 38 can be driven to make a circular motion, so as to stir the cooled and solidified zinc powder and prevent the zinc powder from adhering to the heat exchange box 25.

[0081] S6. When it is necessary to replace the refrigerant in the cooling pipe 47, after the refrigerant is delivered into the cooling pipe 47, the air pressure in the cooling pipe 47 will increase. Under the action of the air pressure, the spherical plate 51 can separate from the mounting base 48, so that the high temperature gas in the cooling pipe 47 can be discharged, so that the refrigerant in the cooling pipe 47 can be replaced.

[0082] However, as is well known to those skilled in the art, the working principle and wiring method of the drive motor 10 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. In the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other.
