Description

Technical Field

[0001] The present application relates to the field of zinc powder production, and in particular to a high-quality zinc powder production device and a process method thereof. Background Art

[0002] Metallic zinc powder is dark gray in color and exhibits excellent reducing properties, rust resistance, and atmospheric corrosion resistance. It can be used as a pigment with exceptional hiding power and is commonly used in the manufacture of rust-proof paints, anti-corrosion coatings, and strong reducing agents. The conventional production method for metallic zinc powder is distillation, which involves heating solid zinc to 1250°C-1350°C to convert it into zinc vapor, which is then condensed in a condenser to form metallic zinc powder.

[0003] Chinese patent publication CN218202981U discloses a continuous zinc powder steam distillation apparatus, specifically comprising a feeder for adding zinc powder feedstock to a melting furnace; a melting furnace for melting the zinc powder feedstock from the feeder; a gasifier for vaporizing the feedstock from the melting furnace; a condensation chamber for condensing the gaseous feedstock from the gasifier; and a slag discharge system for discharging slag from the melting furnace. This patent enables continuous processing, resulting in high efficiency and low cost.

[0004] In the above-mentioned patent, the slag discharge system mainly relies on a slag scoop to discharge the slag. The slag scoop is likely to bring out molten zinc in the process of scooping the slag, thereby causing pollution to the operating environment and even causing safety accidents due to splashing of zinc liquid. Moreover, the efficiency of reciprocating scooping in the vertical direction is poor, making it difficult to quickly remove the slag. Summary of the Invention

[0009] By adopting the above technical solution, the raw materials are first melted in the melting pot, and scum is generated during the melting process.

[0020] By adopting the above technical solution, the connecting rod is adaptively inserted into the mounting groove, and the screw rod and the threaded hole are connected by threads. In this way, the mounting rod with the mounting groove can limit the connecting rod, ensuring that after the screw rod rotates, the connecting rod can move along the length direction of the screw rod, thereby driving the scraper plate to move back and forth along the radial direction of the movable sleeve.

The spring seat is arranged on the base, one end of the support rod is connected to the bottom of the movable sleeve, and the other end of the support rod is connected to the top of the spring seat.

[0023] By adopting the above technical solution, the spring seat is arranged below the furnace body, which reduces the influence of the high temperature in the furnace body on the spring elastic force in the spring seat, thereby ensuring that the dynamic support of the movable sleeve is achieved under the cooperation of the spring seat and the support rod.

[0030] By adopting the above technical solution, the scum scraped out by the scraper plate can completely fall into the material guide trough, making it easy to collect the scum.

[0031] In a second aspect, the present application provides a process for producing high-quality zinc powder, which is implemented using the following technical solutions:

[0032] A high-quality zinc powder production process method, applied to a high-quality zinc powder production device, comprises the following steps:

[0033] S1. Place raw materials in the melting pot, turn on the burner, and heat the melting pot and gasifier;

[0034] S2. The motor drives the screw to rotate and drives the scraper to move horizontally along the radial direction of the movable sleeve to the top side of the movable sleeve. The hydraulic rod drives the scraper to move vertically along the axial direction of the movable sleeve until it contacts the top of the movable sleeve.

[0035] S3, the motor drives the screw to rotate again, so that the scraper moves from one side of the top of the movable sleeve to the other side of the top of the movable sleeve, completing one scraping operation;

[0036] S4. The hydraulic rod pushes the scraper plate, causing the scraper plate to push the movable sleeve downward. At this time, the elastic support assembly is in a compressed state, and then the motor drives the scraper plate to move from the other side of the top of the movable sleeve to the top side of the movable sleeve, completing one scraping operation;

[0037] S5. Repeat step S4 until the scum in the melting pot is completely removed, and finally the raw materials in the melting pot are transported to the vaporization pot. The process is completed.

[0038] By adopting the above technical solution, the scum generated during the melting process can be scraped off efficiently, thereby improving the quality of the finished product of the metal zinc powder.

[0039] Compared with the existing technology, this application has the following beneficial effects:

[0058] Below, combined with the attached Figure 1-7 As well as specific implementation methods, this application is further described. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0059] This embodiment discloses a high-quality zinc powder production device.

[0060] Figure 1 is a schematic three-dimensional diagram of this application, Figure 2 This is a reference diagram of the furnace body, melting pot and vaporization pot in separate states. Figure 1 and Figure 2 A high-quality zinc powder production device includes a heating furnace, which includes a base 8 and a furnace body 1. The bottom of the furnace body 1 is provided with a plurality of legs 80. Supported by the legs 80, the furnace body 1 is suspended. A first accommodating chamber 13 and a second accommodating chamber 14 are provided at the top of the furnace body 1. The first accommodating chamber 13 contains a melting pot 2, and the second accommodating chamber 14 contains a vaporization pot 3. The first accommodating chamber 13 and the second accommodating chamber 14 are connected by a heating channel 15. The burner head 12 is disposed within the heating channel 15. In this way, the heat released by the burner head 12 can be transferred to the first accommodating chamber 13 to heat the melting pot 2, and can also be transferred to the second accommodating chamber 14 to heat the vaporization pot 3. By adjusting the installation position of the burner head 12, reliable control of the feedstock to the melting pot 2 and vaporization pot 3 is achieved. This allows the melting pot 2 to heat the solid feedstock to a molten state. Once the molten feedstock is transferred to the vaporization pot 3, the higher-temperature vaporization pot 3 can heat the molten feedstock to a gaseous state. Furthermore, a cover 11 is provided on the top of the vaporization pot 3. This guide allows the gaseous feedstock to be transferred to subsequent equipment, thereby efficiently completing the production of metallic zinc powder. The feedstock can be transferred between the melting pot 2 and vaporization pot 3 by installing an openable and closable pipe between the two pots, or by pouring or pumping.

[0061] Figure 3 This is a cross-sectional view of the internal structure of the furnace. Figure 4 yes Figure 3 A magnified structure reference diagram. Figure 3 and Figure 4A movable chamber 16 is provided at the top of the furnace body 1. The movable chamber 16 is communicated with the first accommodating chamber 13, and the movable chamber 16 is located at the upper part of the first accommodating chamber 13. The inner diameter of the movable chamber 16 is larger than the inner diameter of the first accommodating chamber 13. In this way, a step surface 160 is formed at the connection between the first accommodating chamber 13 and the movable chamber 16. A movable sleeve 4 is adaptively placed in the movable chamber 16. The height of the movable sleeve 4 is less than the depth of the movable chamber 16. The movable sleeve 4 is sleeved on the outer wall of the melting pot 2. The outer wall of the melting pot 2 is in contact with the inner wall of the first accommodating chamber 13. The outer wall of the movable sleeve 4 is in contact with the inner wall of the movable chamber 16. The lower part of the inner wall of the movable sleeve 4 is in contact with the upper part of the inner wall of the melting pot 2. That is to say, the movable sleeve 4 is sleeved on the upper part of the melting pot 2, and the pot mouth of the melting pot 2 is located on the inner side of the movable sleeve 4. Furthermore, a first annular groove 41 is provided on the inner wall of the movable sleeve 4, and a second annular groove 21 is provided on the top of the melting pot 2. A first clamping ring 42 is adaptively clamped in the first groove 41, and a second clamping ring 22 is adaptively clamped in the second groove 21. An impermeable membrane 9 is provided between the movable sleeve 4 and the melting pot 2, and one end of the impermeable membrane 9 is wound around the first clamping ring 42, and the other end of the impermeable membrane 9 is wound around the second clamping ring 22.

[0062] Figure 5 Schematic diagram of the first clamp ring, the anti-seepage membrane and the second clamp ring. Figure 5 Combined with Figure 4 When installing the anti-seepage membrane 9, first wrap the two ends of the anti-seepage membrane 9 around the first clamping ring 42 and the second clamping ring 22 respectively, and then clamp the first clamping ring 42 into the first groove 41 and the second clamping ring 22 into the second groove 21. In this way, the anti-seepage membrane 9 will cover the gap between the movable sleeve 4 and the melting pot 2, thereby preventing the molten raw materials from penetrating outward from the gap. Moreover, after the installation is completed, the anti-seepage membrane 9 can be in a wrinkled state to ensure that the anti-seepage membrane 9 will not be damaged during the up and down movement of the movable sleeve 4.

[0063] Figure 6 Reference drawing of the assembled state of the melting pot and support assembly. Figure 6 Combined with Figure 3The furnace body 1 is also provided with at least one pair of elastic support components 5, which are symmetrically arranged on both sides of the movable sleeve 4. In this way, the elastic support component 5 can support the movable sleeve 4 more balancedly. Specifically, the elastic support component 5 includes a support rod 51, a limiting tube 53 and a spring seat 52. A through-hole extending downward and passing through the furnace body 1 is provided at the step surface 160. The limiting tube 53 is adaptively installed in the through-hole, and the support rod 51 is passed through the limiting tube 53. The spring seat 52 is arranged on the top of the base 8 and is located below the limiting tube 53. One end of the support rod 51 is connected to the bottom of the movable sleeve 4, and the other end of the support rod 51 is connected to the top of the spring seat 52. In this way, under the support action of the spring seat 52, the movable sleeve 4 is in a fixed state. After the movable sleeve 4 is pressed down, the movable sleeve 4 can slide downward due to the compression of the spring seat 52.

[0064] Figure 7 This is a reference diagram of the position of the furnace body and the drive mechanism. Figure 7 Combined with Figure 1 A drive mechanism 7 is provided on the outside of the furnace body 1, and a scraper 6 is provided above the furnace body 1. The drive mechanism 7 includes a bracket 71 and a linear slide mounted on the bracket 71. The bracket 71 is mounted on the base 8 and on the outside of the furnace body 1. The linear slide includes a mounting rod 72, a motor 73, a screw 74, and a connecting rod 75. The mounting rod 72 extends radially along the melting pot 2. A mounting groove 720 is provided on the side wall of the mounting rod 72. The screw 74 is inserted into the mounting groove 720. The motor 73 is used to drive the screw 74 to rotate. The radial cross-section of the connecting rod 75 is rectangular. One end of the connecting rod 75 is inserted into the mounting groove 720 and abuts against the inner wall of the mounting groove 720. In this way, the connecting rod 75 can only slide within the mounting groove 720 but cannot rotate within the mounting groove 720. At the same time, one end of the connecting rod 75 is provided with a threaded hole 750. The screw 74 is screwed into the threaded hole 750, thus forming a threaded connection between the screw 74 and the connecting rod 75. A hydraulic rod 76 is provided at one end of the connecting rod 75 away from the mounting rod 72 . The push rod of the hydraulic rod 76 is connected to the scraper plate 6 . The hydraulic rod 76 is used to push the scraper plate 6 to move axially along the melting pot 2 .

[0065] As the raw materials are added to the melting pot 2 and melted into a molten state, scum is continuously generated and floats on top of the raw materials. By adding a sufficient amount of raw materials, the liquid level of the raw materials can be controlled so that the scum is slightly higher than the height of the movable sleeve 4. In other words, after the raw materials are melted, the liquid level of the raw materials does not exceed the height of the top of the movable sleeve 4, while the top layer of the piled scum can be higher than the height of the top of the movable sleeve 4. When the raw materials are completely melted and the scum is large, the motor 73 drives the screw rod 74 to rotate, thereby achieving radial movement of the connecting rod 75 in the melting pot 2, thereby driving the scraper plate 6 to move synchronously. When the scraper plate 6 moves to one side and above the movable sleeve 4, the motor 73 stops rotating, and the push rod of the hydraulic rod 76 then pushes the scraper plate 6 downward so that the scraper plate 6 can fit the top of the movable sleeve 4. After the driving mechanism 7 has completed the initial position adjustment of the scraper plate 6, the scraper plate 6 is only in contact with the outer edge of the top side of the movable sleeve 4. At this time, the motor 73 drives the scraper plate 6 to move again, so that the scraper plate 6 can move from the top side of the movable sleeve 4 to the other side of the top of the scraper plate 6. In this process, the scum at the top can be scraped off by the scraper plate 6, thereby achieving efficient removal of the scum.

[0066] After the scraper blade 6 moves from one side of the top of the movable sleeve 4 to the other side, completing one scraping operation, the hydraulic rod 76 then drives the movable sleeve 4 downward for a certain distance. At this point, the liquid level of the molten material is closer to the top of the movable sleeve 4, allowing a portion of the scum to rise above the height of the scraper blade 6. The motor 73 drives the scraper blade 6 again, causing it to move from the other side of the top of the movable sleeve 4 to the one side of the top of the movable sleeve 4, completing another scraping operation. Thus, after each scraping operation, the scraper blade 6 is pressed downward, exerting pressure on the movable sleeve 4, thereby gradually bringing the liquid level of the molten material closer to the top of the movable sleeve 4. This improves the efficiency of scum removal and prevents a large amount of scum from overflowing or being carried out of the material, which could create a safety hazard. During the downward pressure of the movable sleeve 4, the spring seat 52 is gradually compressed. After the scum removal is completed, the spring seat 52 releases its energy and rebounds, allowing the movable sleeve 4 to return to its original position. Furthermore, under the protection and isolation function of the anti-seepage membrane 9, the raw materials will not leak.

[0067] The width of the scraper plate 6 is greater than the inner diameter of the movable sleeve 4, and the thickness of the scraper plate 6 is less than the wall thickness of the movable sleeve 4. In this way, the scraper plate 6 is long and flat, ensuring that the entire movable sleeve 4 can be covered in one scraping. The thickness of the scraper plate 6 is relatively small and the wall thickness of the movable sleeve 4 is relatively large, ensuring that after the scraper plate 6 finishes scraping the slag once, the scraper plate 6 can still maintain a state of mutual fit with the top of the movable sleeve 4, preventing the movable sleeve 4 from automatically resetting under the action of the spring seat 52 before the slag removal operation is completed. Furthermore, two material guide troughs 17 are provided on the top of the furnace body 1, and the two material guide troughs 17 are symmetrically arranged on both sides of the melting pot 2. The height of the end of the material guide trough 17 close to the melting pot 2 is greater than the height of the end of the material guide trough 17 away from the melting pot 2, and the width of the material guide trough 17 is greater than the outer diameter of the movable sleeve 4. In this way, the scum scraped off by the scraper plate 6 can completely fall into the material guide trough 17 and slide along the material guide trough 17 to the outside of the furnace body 1, which is convenient for collecting the scum and preventing pollution of the operating environment.

[0068] This embodiment also discloses a process for producing high-quality zinc powder.

[0069] A high-quality zinc powder production process method, applied to a high-quality zinc powder production device, comprises the following steps:

[0070] S1. Put raw materials into the melting pot 2, turn on the burner 12, and heat the melting pot 2 and the gasification furnace;

[0071] S2, the motor 73 drives the screw 74 to rotate and drive the scraper 6 to move horizontally along the radial direction of the movable sleeve 4 to the top side of the movable sleeve 4, and the hydraulic rod 76 drives the scraper 6 to move vertically along the axial direction of the movable sleeve 4 until it contacts the top of the movable sleeve 4;

[0072] S3, the motor 73 drives the screw 74 to rotate again, so that the scraper 6 moves from one side of the top of the movable sleeve 4 to the other side of the top of the movable sleeve 4, completing one scraping operation;

[0073] S4, the hydraulic rod 76 pushes the scraper plate 6, so that the scraper plate 6 pushes the movable sleeve 4 to move downward. At this time, the elastic support assembly 5 is in a compressed state, and then the motor 73 drives the scraper plate 6 to move from the other side of the top of the movable sleeve 4 to the top side of the movable sleeve 4, completing one scraping operation;

[0074] S5. Repeat step S4 until the scum in the melting pot 2 is completely removed, and finally the raw materials in the melting pot 2 are transported to the vaporizing pot 3. Finished.

Any non-substantial changes and replacements made by technicians in this field based on the present application shall fall within the scope of protection required by the present application.
