[0022] A production method is applied in the production equipment of zinc powder for the above-mentioned sherardizing process, comprising the following steps: S1, connection and flow control: connecting the joint to the external zinc vapor delivery pipeline, rotating the rotating plate to drive the screw to rotate, and driving the movable cover to move longitudinally through the threaded tube to adjust the connection area between the flow hole and the support tube to control the zinc vapor flow.
[0023] S2. Zinc vapor cooling and zinc powder formation: High-temperature zinc vapor is transported to the support pipe, enters the mobile cover through the flow hole, and then enters the heat exchange box through the installation pipe. The heat exchange box is immersed in water with a low temperature, which cools the zinc vapor to form zinc powder.
[0024] S3, cooling and zinc powder collection: start the water pump to pump water from the annular box to the cooling box to cool the zinc vapor. After the outlet pipe is connected to the connecting pipe, the water in the cooling box is transported back to the annular box. The zinc powder formed by cooling falls into the rotating box and falls on the second filter screen tube.
[0025] S4.

Refrigerant replacement: When replacing the refrigerant in the cooling pipe, the refrigerant is transported into the cooling pipe, the increased air pressure pushes the spherical plate to separate from the mounting seat, and the high-temperature gas is discharged to facilitate the replacement of the refrigerant.
[0028] It is to be understood that the foregoing general description and the following detailed description are exemplary only and are not restrictive of the invention.
[0029] Compared with the prior art, the present invention has the following beneficial effects:
[0030] In the present invention, the separation mechanism can be set to drive the rotating box to rotate after the power assembly is started. At this time, the zinc powder dropped into the second filter mesh tube will perform centrifugal motion and pass through the second filter mesh tube and the first filter mesh tube in sequence. Since the aperture of the first filter mesh tube is smaller than the aperture of the second filter mesh tube, when screening the zinc powder, multi-stage screening of the zinc powder can be achieved, which is convenient for the subpackaging of the zinc powder.
[0031] The present invention is also provided with a heat exchange mechanism, which can transport zinc vapor in a high temperature state into the ventilation component after the ventilation component is connected to the external zinc vapor delivery pipeline. At the same time, after the water inlet pipe is connected to the cooling mechanism, the cooled water is transported to the water inlet pipe and further transported to the cooling box. Under the action of the heat exchange principle, the zinc vapor is cooled and forms zinc powder. Afterwards, the water flows back to the cooling mechanism through the water outlet pipe, realizing the circulation of water, thereby continuously cooling the zinc vapor.
[0032] In addition, the present invention is also equipped with a cooling mechanism, which pumps out the water in the annular box by starting a water pump and transports it to the cooling box, thereby injecting cold water into the cooling box to cool the zinc vapor. After the water outlet pipe is docked with the connecting pipe, the water in the cooling box can be transported back to the annular box. At the same time, the cooling pipe is connected to the external refrigerant mechanism, and the refrigerant medium can be transported into the cooling pipe to cool the water in the annular box and keep the water in a low temperature state.
[0033] The present invention also provides a vibration mechanism, which meshes with the transmission ring gear when the connecting gear rotates with the output shaft of the driving motor, thereby driving the transmission ring gear and the nut to rotate. When the nut rotates, the reciprocating screw performs longitudinal reciprocating motion through the threaded transmission action with the reciprocating screw. When the reciprocating screw moves upward, the hammer head will hit the rotating box, causing it to vibrate. In this way, when screening zinc powder, it can be avoided that the zinc powder is stuck on the first filter mesh tube and the second filter mesh tube. At the same time, the push rod is elastically supported by the first compression spring to ensure that the knocking force on the rotating box is not too large during actual use, thereby avoiding damage to the rotating box.
[0034] In summary, when the zinc vapor is cooled to form zinc powder, the present invention can process the zinc powder or zinc vapor in a relatively closed environment, thereby avoiding the problem of oxidation of the produced zinc. At the same time, after the zinc powder is produced, the present invention can also realize the sorting of the zinc powder, which is convenient for the classification and packaging of the zinc powder, and thus has good practicality.

DETAILED DESCRIPTION
[0046] The embodiments of the present invention are described below in conjunction with the accompanying drawings in the embodiments of the present invention.

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.

The directional terms mentioned in the embodiments of the present invention, such as "inside", "outside", "top", "bottom", etc., are only reference to the directions of the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present invention.
[0048] Example 1
[0049] Reference Figure 1-Figure 10 The production equipment of zinc powder for zincizing process of this embodiment includes a base frame 1, a bottom box 2, an electric push rod 3, a closed box 4 and a plurality of functional mechanisms. The base frame 1 serves as the supporting structure of the whole equipment, and a bottom box 2 is fixedly installed on the top thereof. Two electric push rods 3 are symmetrically installed on the bottom inner wall of the bottom box 2, and the output shafts of the two electric push rods 3 extend upward, pass through the top of the bottom box 2, and are fixedly connected to a sealing ring 5. The sealing ring 5 is tightly matched with the top of the bottom box 2 to ensure the sealing performance. At the same time, a closed box 4 is fixedly installed on the top of the sealing ring 5 to form a closed working environment.
[0050] Separation mechanism: Inside the bottom box 2, a rotating box 6 is installed, and the rotating box 6 is rotatably connected to the bottom box 2 through a rotating connection such as a bearing. Inside the rotating box 6, a first filter mesh tube 7 and a second filter mesh tube 8 are fixedly installed from top to bottom, and the second filter mesh tube 8 is nested inside the first filter mesh tube 7. This design allows the two to form filter layers with different apertures.
[0051] A power assembly is installed at the bottom of the rotating box 6, and the power assembly includes a rotating gear ring 12 fixedly installed at the bottom of the rotating box 6, and a driving motor 10 installed at one side of the bottom of the bottom box 2. The output shaft of the driving motor 10 passes through the side wall of the bottom box 2 and is fixedly connected to a driving gear 11, which is meshed with the rotating gear ring 12. When the driving motor 10 is started, the rotating box 6 is driven to rotate through the meshing transmission of the driving gear 11 and the rotating gear ring 12.
[0052] The rotating rotating box 6 causes the zinc powder falling into the second filter mesh tube 8 to be subjected to centrifugal force, thereby achieving graded screening. Since the aperture of the first filter mesh tube 7 is smaller than that of the second filter mesh tube 8, the zinc powder will first pass through the second filter mesh tube 8 for preliminary screening, and then pass through the first filter mesh tube 7 for more detailed screening, achieving a multi-stage screening effect.
[0053] Vibration mechanism: A mounting hole is opened on the inner wall of the bottom of the bottom box 2, and a vibration mechanism is installed. The specific structure is not specified in detail, but it can be conceived as an electromagnetic vibrator or a mechanical knocking device. The vibration mechanism passes through the mounting hole and is connected to the inner wall of the mounting hole, and is also connected to the power assembly in the separation mechanism, namely the drive motor 10 and the driving gear 11, to achieve synchronous or asynchronous vibration effects. The function of the vibration mechanism is to knock on the separation mechanism rotating box 6, which helps prevent zinc powder from clogging the filter mesh tube and improves the screening efficiency.
[0054] Heat exchange mechanism: The heat exchange mechanism is installed on the top inner wall of the closed box 4, and its top extends to the outside of the closed box 4, and its two sides extend to the two sides of the closed box 4, so as to be connected to the external heat source or cold source. The bottom of the heat exchange mechanism extends to the inside of the second filter mesh tube 8 and is connected to the bottom of the rotating box 6. The 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 sherardizing process.
[0055] Cooling mechanism: The cooling mechanism is designed as a structure mounted on the bottom box 2, connected 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, an air cooling device, etc., which is used to dissipate the heat transferred by the heat exchange mechanism to ensure stable operation of the equipment.
[0056] Through the above specific implementation, the production equipment of zinc powder for the sherardizing process can realize efficient and multi-stage screening of zinc powder, and meet the requirements of the sherardizing process for zinc powder temperature and quality through the synergistic effect of the heat exchange mechanism and the cooling mechanism.
[0057] Heat exchange mechanism: A cooling box 24 is fixedly mounted on the top center inner wall of the closed box 4. The cooling box 24 is designed as a sealed structure, with a water inlet pipe 44 fixedly mounted on the top inner wall on one side, and a water outlet pipe 45 fixedly mounted on the bottom inner wall on the other side. The water inlet pipe 44 and the water outlet pipe 45 extend to both sides of the closed box 4 respectively, and are connected to the external cooling mechanism to form a cooling water circulation system.
[0058] The cooling box 24 is used to hold cooling water. When the high-temperature zinc vapor enters the closed box 4 through the ventilation assembly, the cooling water in the cooling box 24 cools the zinc vapor through the heat exchange principle, 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 recycling.
[0059] Ventilation assembly: The core part of the ventilation assembly is a mounting pipe 27 that penetrates the closed box 4 and is fixedly connected to the top inner wall thereof. A support pipe 28 is provided inside the mounting pipe 27, and the top end of the support pipe 28 extends above the mounting pipe 27 to facilitate connection to an external zinc vapor delivery pipeline.
[0060] A joint 29 is fixedly installed on one inner wall of the support tube 28 , and one end of the joint 29 extends to the outside of the support tube 28 for connecting to an external zinc vapor delivery pipeline.
[0061] A mounting ring 31 is also fixedly installed inside the support tube 28, and a moving cover 32 is slidably connected inside the mounting ring 31. Flow holes 33 are provided on the inner walls on both sides of the moving cover 32 to control the flow rate of zinc vapor. A threaded tube 35 is fixedly installed on the top of the moving cover 32, and a screw 36 is threadedly connected inside the threaded tube 35. The top end of the screw 36 extends to the top of the support tube 28, and a rotating plate 30 is fixedly installed. 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 driven to rotate in the threaded tube 35, and then the moving cover 32 can be driven to move up and down to adjust the connection area between the flow hole 33 and the support tube 28, thereby realizing the control of the flow rate of zinc vapor.
[0062] A heat exchange box 25 is fixedly mounted at the bottom end of the mounting tube 27. A plurality of annular flanges 26 are arranged at equal intervals on the outer wall of the heat exchange box 25 to increase the heat exchange area. When the zinc vapor passes through the support tube 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 here and condensed into zinc powder.
[0063] In the heat exchange box 25, two stirring racks 38 are symmetrically slidably connected, and the two stirring racks 38 are 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 is connected to the bottom inner wall of the rotating box 6.
[0064] A conical column 9 is fixedly mounted on the inner wall of the bottom of the rotating box 6. An adapting groove is formed on the top of the conical column 9. Two clamping grooves are symmetrically formed on the inner wall of the bottom of the adapting groove. The bottom end of the rotating rod 37 extends into the adapting groove and a chuck 39 is fixedly mounted thereon. Two clamping points 40 are symmetrically fixedly mounted on the bottom of the chuck 39. The two clamping points 40 extend into the corresponding clamping grooves respectively and are movably clamped with the clamping grooves.
[0065] When the rotating box 6 rotates under the drive of the power assembly, the conical column 9 rotates accordingly. Due to the clamping fit between the clamping point 40 and the clamping slot, the rotation of the rotating box 6 can drive the rotating rod 37 to rotate synchronously, thereby driving the two stirring racks 38 to perform circular motion in 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 mounted on the bottom box 2. A water pump 42 is fixedly installed on one side of the top of the annular box 41, and its water suction end extends into the annular box 41 to extract cooling water, and the water outlet end is connected to a butt pipe 43, the top end of which extends into the water inlet pipe 44 and is clamped with its inner wall to ensure a sealed connection.
[0067] A connecting pipe 46 is fixedly mounted on the inner wall on the other side of the top of the annular box 41 , and the top end of the connecting pipe 46 extends to the top of the annular box 41 and is engaged with the water outlet pipe 45 to form a reflux path for cooling water.
[0068] Cooling pipe arrangement: A cooling pipe 47 is fixedly installed inside the annular box 41, and both ends of the cooling pipe 47 extend to the outside of the annular box 41. One end is used to connect to an external refrigerant mechanism, and the other end is installed with a plugging component.
[0069] A tubular mounting seat 48 is fixedly mounted at the other end of the cooling tube 47, and a support plate 49 is fixed inside. A support rod 50 is slidably connected to the support plate 49, and a spherical plate 51 is fixedly mounted on one end of the support rod 50, which is tightly fitted with the inner wall of the mounting seat 48. A second compression spring 52 is sleeved on the support rod 50, and its two ends are respectively fixedly connected to the other end of the support rod 50 and one side of the support plate 49, providing stable elastic support.
[0070] Working principle: Start the water pump 42, pump out the water in the annular box 41 and transport it to the cooling box 24 to cool the zinc vapor. Then, the water flows back to the annular box 41 through the water outlet pipe 45 and the connecting pipe 46. At the same time, the external refrigerant mechanism transports the refrigerant medium to the cooling pipe 47 to cool the water in the annular box 41 and maintain its low temperature state. When the refrigerant in the cooling pipe 47 needs to be replaced, the air pressure in the cooling pipe 47 increases due to the input of the refrigerant, pushing the spherical plate 51 to separate from the mounting seat 48, thereby discharging the high-temperature gas, which is convenient for replacing the refrigerant.
[0071] Vibration mechanism: A transmission gear ring 14 is rotatably connected to the inner wall of the bottom of the bottom box 2, and a mounting plate 15 is fixedly installed inside the gear ring 14. 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 bottom box 2, and a limit plate 18 is fixedly installed. The two sides are slidably connected through a limit frame 19 to ensure stability.
[0072] A connecting gear 13 is fixedly sleeved on the output shaft of the driving motor 10 and meshes with the transmission gear ring 14. When the driving motor 10 is working, the connecting gear 13 drives the transmission gear ring 14 to rotate, thereby driving the nut 16 to rotate.
[0073] Due to the threaded connection between the nut 16 and the reciprocating screw 17, when the nut 16 rotates, the reciprocating screw 17 is driven to perform longitudinal reciprocating motion. A connection groove 20 is provided at the top of the reciprocating screw 17, and a push rod 21 is slidably connected inside. 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 head 22 strikes the rotating box 6 to vibrate it, thereby preventing zinc powder from getting stuck on the first filter mesh tube 7 and the second filter mesh tube 8. At the same time, the elastic support of the first compression spring 23 prevents excessive striking force from damaging the rotating box 6. The design of the vibration mechanism improves the efficiency and effect of zinc powder screening.
[0075] The present invention provides a production method, which is applied to the production equipment of zinc powder for the above-mentioned sherardizing process, comprising the following steps:
[0076] S1. Connect the joint 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 threaded transmission action with the threaded tube 35, the movable cover 32 can be driven to move longitudinally, so as to adjust the communication area between the flow hole 33 and the support tube 28, so as to control the flow rate of the zinc vapor;
[0077] S2, the zinc vapor in the high temperature state is transported to the support tube 28, and then the zinc vapor can be transported to the movable cover 32 through the two flow holes 33, and then the zinc vapor 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 relatively low. At this time, when the zinc vapor is transported to the heat exchange box 25, it can be cooled so as to form zinc powder;
[0078] S3, start the water pump 42 to pump out the water in the annular box 41, and then transport it to the cooling box 24, so that cold water can be injected into the cooling box 24 to cool the zinc vapor, so that the zinc vapor is cooled to form zinc powder, and 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, and the zinc powder formed by cooling can fall into the rotating box 6 and fall into the range of the second filter mesh tube 8;
[0079] S4, start the driving motor 10 to drive the driving gear 11 to rotate, and 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, so that when the zinc powder falls on the second filter mesh tube 8, it can have centrifugal force, so that the zinc powder can pass through the second filter mesh tube 8 and the first filter mesh tube 7 respectively, and the aperture of the first filter mesh tube 7 is smaller than that of the second filter mesh tube 8, so when the zinc powder is screened, it can be screened in multiple stages, so as to package the zinc powder;
[0080] S5. When the conical column 9 rotates with the rotating box 6, the rotating rod 37 can be driven to rotate by the card point 40 and the card slot, and the two stirring racks 38 can be driven to perform 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 the refrigerant in the cooling tube 47 needs to be replaced, after the refrigerant is transported into the cooling tube 47, the air pressure in the cooling tube 47 will increase, and the spherical plate 51 can be separated from the mounting seat 48 under the driving force of the air pressure, so that the high-temperature gas in the cooling tube 47 can be discharged, so that the refrigerant in the cooling tube 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 conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any selections according to their needs or convenience.
[0083] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention; the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
