Description

Technical Field

[0001] This invention belongs to the field of vacuum flaking machine technology, specifically, it relates to a gas-phase feeding vacuum flaking machine. Background Technology

[0002] In industrial applications of vapor phase vacuum flaking machines, their core function is to spray vapor phase raw materials onto the surface of cooling rollers in a vacuum environment to condense and crystallize them into continuous sheet-like finished products. The synergistic performance of the regulating pipe, main outlet, and vacuum tube is the key factor that determines the raw material utilization rate, condensation efficiency, and flaking stability.

[0003] In modern vacuum flaking machines, the inlet pipe slides inside to ensure uniform condensation. However, when the regulating pipe moves to the center, due to the distance between them, the impact force of some gaseous raw materials rushing towards the surface of the cooling roller is insufficient. This makes it difficult to overcome the negative pressure adsorption force formed in the central area due to the proximity of the vacuum pipe. Some raw materials are sucked away before contacting the roller surface, further aggravating raw material loss. In addition, insufficient flow rate prevents the raw materials from quickly and accurately reaching the designated area on the roller surface, affecting the uniformity and continuity of flaking.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows: A gas-phase feeding vacuum flaking machine includes a gas-phase vacuum flaking machine body and an inlet hood for feeding gaseous raw materials into the gas-phase vacuum flaking machine body.

[0006] The vapor phase vacuum slagging machine body is equipped with a vacuum tube; The bottom of the vapor phase vacuum sintering machine body is provided with three pairs of gas supply pipes, and the gas supply pipe located in the center position is vertically aligned with the cooling roller of the vapor phase vacuum sintering machine body. An adjusting tube is installed through the gas supply pipe located at the center. A top rod is installed at the bottom of the adjusting tube. The bottom of the top rod is slidably connected to a guide block installed on the air inlet hood. The height of the two ends of the guide block is higher than the height of the center. When the gas supply pipe slides towards the center, the adjusting tube moves down along the guide block to ensure that the straight distance between the adjusting tube and the vacuum tube remains unchanged. Conical through holes are installed inside the gas supply pipes located on both sides. Conical plugs are inserted into the conical through holes. A pull rod is installed at the bottom of the conical plug, and the pull rod slides synchronously with the push rod. When the gas supply pipe located in the center position moves to the center position, the distance between the top of the regulating pipe and the cooling roller of the gas phase vacuum slagging machine body becomes shorter, and the push rod drives the conical plug conical through hole to move, reducing the gap, thereby increasing the speed of gas flowing out of the regulating pipe, so that the gas contacts the cooling roller of the gas phase vacuum slagging machine body.

[0007] In a preferred embodiment of the present invention, a frame is installed on the outer wall of the vapor phase vacuum slagging machine body. Four support legs are installed at the bottom corner of the frame, and reinforcing ribs are installed between adjacent support legs. The heights between adjacent reinforcing ribs are different. A column is installed on the frame, and a base plate is installed on the side wall of the column. An inclined rod is installed on the base plate, and the end of the inclined rod is connected to the side wall of the column. The inclined rod is in an inclined state. The base plate forms an installation platform. An observation window is also installed on the vapor phase vacuum slagging machine body.

[0008] In a preferred embodiment of the present invention, a fixing plate is installed on the frame, the end of the fixing plate is connected to the air intake hood, an air intake pipe is installed on the side wall of the air intake hood, a connecting flange is installed at the end of the air intake pipe, the connecting flange facilitates connection with external structures, and a limiting seat is installed on the air intake pipe, the limiting seat is installed on the frame.

[0009] In a preferred embodiment of the present invention, the end of the air inlet pipe is connected to the gas phase raw material conveying system, the vacuum pipe is connected to the vacuum system, and a controller is also installed on the frame. The controller is used to adjust the conveying speed of the gas phase raw material conveying system and the extraction speed of the vacuum system.

[0010] In a preferred embodiment of the present invention, the vapor phase vacuum flaking machine body has a notch, and three pairs of sealing plates are slidably installed at the bottom of the vapor phase vacuum flaking machine body. The sealing plates are used to seal the notch, and the sealing plates are always in contact with the notch during the sliding process. The top of the sealing plate is connected to the gas supply pipe, and a slide is installed at the bottom of the sealing plate. A slide rod is installed through the slide. One end of the slide rod is installed on the side wall of the air inlet hood, and a sliding plate is installed at the other end of the slide rod. The diameter of the sliding plate is larger than the diameter of the slide rod.

[0011] In a preferred embodiment of the present invention, an electric push rod is installed on the side wall of the air intake hood, the output end of the electric push rod penetrates through the side wall of the air intake hood, and a connecting frame is installed on the output end of the electric push rod. Three pairs of connecting plates are installed on the connecting frame, and the ends of the connecting plates are connected to the corresponding sealing plates.

[0012] In a preferred embodiment of the present invention, a mounting base is installed at the bottom of the regulating pipe located at the center, a top rod is installed at the center of the mounting base, a ball is installed at the bottom of the top rod, the ball is slidably disposed on the guide block, and the surface of the guide block is arc-shaped, and a main air outlet is opened at the top of the regulating pipe.

[0013] In a preferred embodiment of the present invention, a pressure plate is installed at the bottom of the adjusting tube, a limiting rod is installed through the pressure plate, a limiting plate is installed at the bottom of the limiting rod, the top of the limiting rod is installed at the bottom of the sealing plate, a limiting spring is sleeved on the limiting rod, one end of the limiting spring is clamped on the pressure plate, and the other end of the limiting spring is clamped at the bottom of the sealing plate. The limiting spring is used to ensure that the top rod always has a force that fits against the surface of the guide block.

[0014] In a preferred embodiment of the present invention, a timing frame is installed at the bottom of the pull rod, the center of the timing frame is connected to the side wall of the top rod, and a through groove is provided on the timing frame, the through groove being movable through the limiting rod.

[0015] In a preferred embodiment of the present invention, a fixing seat is movably inserted into the side wall of the pull rod, and the side wall of the fixing seat is installed on the side wall of the gas transmission pipe located on both sides, and an auxiliary gas outlet is opened at the top of the gas transmission pipe located on both sides.

[0016] Compared with the prior art, the present invention has the following advantages: The regulating tube of this invention moves downward along the arc surface of the guide block via a push rod, maintaining a stable distance from the vacuum tube. This avoids negative pressure suction from a positional perspective. Furthermore, when the regulating tube is in the center position, it automatically increases the flow rate at the main outlet, enhancing the impact force of the gaseous raw material on the surface of the cooling roller. This effectively counteracts the suction force of negative pressure on the raw material, ensuring that the raw material in the central area quickly reaches the roller surface instead of being sucked away by negative pressure. This further reduces the loss of raw material before transmission and condensation. The higher jet speed at the main outlet also allows the raw material in the central area to contact the low-temperature surface of the cooling roller more quickly and powerfully, shortening the time from jetting to condensation and reducing the probability of the raw material being affected by negative pressure during its stay in the cavity, thus improving condensation efficiency.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0021] Example 1: like Figures 1 to 11 As shown, a gas-phase feeding vacuum flaking machine includes a gas-phase vacuum flaking machine body 1 and an inlet hood 12 for feeding gaseous raw materials to the gas-phase vacuum flaking machine body 1.

[0022] Vacuum tube 13 is installed on the main body 1 of the vapor phase vacuum slagging machine; Three pairs of gas delivery pipes 152 are slidably arranged at the bottom of the vapor phase vacuum sintering machine body 1. The gas delivery pipe 152 located in the center position is vertically aligned with the cooling roller of the vapor phase vacuum sintering machine body 1. An adjusting pipe 2 is installed through the gas supply pipe 152 located at the center. A push rod 21 is installed at the bottom of the adjusting pipe 2. The bottom of the push rod 21 is slidably connected to the guide block 22 installed on the air inlet hood 12. The height of the two ends of the guide block 22 is higher than the height of the center. When the gas supply pipe 152 slides towards the center, the adjusting pipe 2 moves down along the guide block 22 to ensure that the straight distance between the adjusting pipe 2 and the vacuum tube 13 remains unchanged. The gas supply pipes 152 located on both sides are equipped with conical through holes 25. Conical plugs 251 are inserted into the conical through holes 25. A pull rod 242 is installed at the bottom of the conical plug 251. The pull rod 242 slides synchronously with the top rod 21. When the gas supply pipe 152 located in the center position moves to the center position, the distance between the top of the regulating pipe 2 and the cooling roller of the gas phase vacuum slagging machine body 1 becomes shorter. The top rod 21 drives the conical plug 251 to move the conical through hole 25, reducing the gap, thereby increasing the speed of gas flowing out of the regulating pipe 2, so that the gas comes into contact with the cooling roller of the gas phase vacuum slagging machine body 1. The main body 1 of the gas phase vacuum slagging machine provides the core space for slagging, the gas inlet hood 12 ensures stable delivery of gas raw materials, the vacuum tube 13 ensures a vacuum environment inside the cavity, and three pairs of gas delivery pipes 152 ensure accurate delivery direction of raw materials. The regulating pipe 2, the push rod 21 and the guide block 22 work together to maintain a stable distance between the regulating pipe 2 and the vacuum tube 13. The conical through holes 25, conical plugs 251 and pull rods 242 of the gas delivery pipes on both sides synchronously adjust the airflow speed, ultimately ensuring that the gas raw materials contact the cooling roller efficiently and improve the slagging efficiency.

[0023] like Figures 1 to 11 As shown in the specific embodiment, a frame 11 is installed on the outer wall of the vapor phase vacuum slagging machine body 1. Four support legs are installed at the bottom corner of the frame 11, and reinforcing ribs 111 are installed between adjacent support legs. The heights between adjacent reinforcing ribs are different. A column 112 is installed on the frame 11, and a base plate 113 is installed on the side wall of the column 112. An inclined rod 114 is installed on the base plate 113, and the end of the inclined rod 114 is connected to the side wall of the column 112. The inclined rod 114 is in an inclined state. The base plate 113 forms an installation platform. An observation window 14 is also installed on the vapor phase vacuum slagging machine body 1. The frame 11 and support legs provide stable support for the entire equipment. The reinforcing ribs 111 of different heights enhance the structural strength of the frame 11 and prevent the equipment from shaking during operation. The column 112, base plate 113 and inclined rod 114 cooperate to form a stable installation platform, which facilitates the installation of other components. The observation window 14 allows real-time observation of the slagging situation in the cavity, which facilitates timely adjustment of the process.

[0024] like Figures 1 to 11As shown, a fixing plate 121 is further installed on the frame 11. The end of the fixing plate 121 is connected to the air intake hood 12. An air intake pipe 122 is installed on the side wall of the air intake hood 122. A connecting flange 123 is installed at the end of the air intake pipe 122. The connecting flange 123 facilitates connection with external structures. A limit seat 124 is installed on the air intake pipe 122 and is mounted on the frame 11. The fixing plate 121 achieves a stable connection between the frame 11 and the air intake hood 12, ensuring the stability of the position of the air intake hood 12. The air intake pipe 122 provides a conveying channel for gaseous raw materials. The connecting flange 123 simplifies the connection process between the air intake pipe 122 and the external gas phase raw material conveying system. The limit seat 124 fixes the position of the air intake pipe 122 and prevents the air intake pipe 122 from shifting due to airflow impact.

[0025] like Figures 1 to 11 As shown, the end of the inlet pipe 122 is connected to the gaseous raw material delivery system, and the vacuum pipe 13 is connected to the vacuum system. A controller is also installed on the frame 11. The controller is used to adjust the delivery speed of the gaseous raw material delivery system and the extraction speed of the vacuum system. The connection between the inlet pipe 122 and the gaseous raw material delivery system ensures a continuous supply of gaseous raw materials, and the connection between the vacuum pipe 13 and the vacuum system ensures that the vacuum level in the cavity meets the process requirements. The controller can precisely adjust the raw material delivery speed and the vacuum extraction speed to achieve dynamic optimization of process parameters and maintain the stability of the flake formation process.

[0026] like Figures 1 to 11 As shown, further, a notch 15 is provided on the main body 1 of the vapor phase vacuum slagging machine. Three pairs of sealing plates 151 are slidably installed at the bottom of the main body 1 of the vapor phase vacuum slagging machine. The sealing plates 151 are used to seal the notch 15. During the sliding process, the sealing plates 151 are always in contact with the notch 15. The top of the sealing plates 151 is connected to the gas supply pipe 152. A slide block 153 is installed at the bottom of the sealing plates 151. A slide rod 154 is installed through the slide block 153. One end of the slide rod 154 is installed on the side wall of the air inlet hood 12. The other end of the slide rod 154 is installed with a sliding plate 155. The diameter of the sliding plate 155 is larger than the diameter of the slide rod 154. The notch 15 provides space for the sliding of the gas supply pipe 152. The three pairs of sealing plates 151 always fit the notch 15 during sliding, effectively preventing vacuum leakage in the cavity. The connection between the sealing plate 151 and the gas supply pipe 152 enables them to move synchronously. The slide block 153 and the slide rod 154 cooperate to ensure that the sealing plate 151 slides smoothly. The slide plate 155 prevents the slide block 153 from disengaging from the slide rod 154, ensuring the stability of the sliding stroke of the sealing plate 151.

[0027] like Figures 1 to 11As shown, an electric push rod 16 is further installed on the side wall of the air intake shroud 12. The output end of the electric push rod 16 penetrates through the side wall of the air intake shroud 12, and a connecting frame 161 is installed on the output end of the electric push rod 16. Three pairs of connecting plates 162 are installed on the connecting frame 161, and the ends of the connecting plates 162 are connected to the corresponding sealing plates 151. The electric push rod 16 provides the power required for the sliding of the sealing plates 151. The connecting frame 161 and the three pairs of connecting plates 162 cooperate to achieve the uniform transmission of power from the electric push rod 16 to each sealing plate 151, ensuring that the three pairs of sealing plates 151 slide synchronously, thereby ensuring the consistency of the position adjustment of the air supply pipe 152.

[0028] Example 2: The difference between the above embodiments and this embodiment is that: Figures 1 to 11 As shown, a mounting base 211 is installed at the bottom of the regulating pipe 2 located at the center. A push rod 21 is installed at the center of the mounting base 211, and a ball bearing 212 is installed at the bottom of the push rod 21. The ball bearing 212 is slidably mounted on the guide block 22, and the surface of the guide block 22 is arc-shaped. A main air outlet 213 is opened at the top of the regulating pipe 2. The mounting base 211 realizes a stable connection between the push rod 21 and the regulating pipe 2, ensuring that the push rod 21 is under stable force. The ball bearing 212 converts the sliding friction between the push rod 21 and the guide block 22 into rolling friction, reducing wear and improving sliding smoothness. The arc-shaped guide block 22 facilitates the smooth downward movement of the push rod 21. The main air outlet 213 allows the gas raw material to be concentrated and sprayed out, further improving the contact efficiency between the raw material and the cooling roller.

[0029] like Figures 1 to 11 As shown, in a specific embodiment, a pressure plate 23 is installed at the bottom of the regulating pipe 2. A limiting rod 231 is installed through the pressure plate 23. A limiting plate 232 is installed at the bottom of the limiting rod 231. The top of the limiting rod 231 is installed at the bottom of the sealing plate 151. A limiting spring 233 is sleeved on the limiting rod 231. One end of the limiting spring 233 is engaged with the pressure plate 23, and the other end is engaged with the bottom of the sealing plate 151. The limiting spring 233 is used to ensure that the top rod 21 always has a force that adheres to the surface of the guide block 22. The pressure plate 23 provides a mounting base for the limiting rod 231. The limiting rod 231 and the limiting plate 232 cooperate to limit the movement range of the pressure plate 23, preventing the regulating pipe 2 from moving excessively. The limiting spring 233 uses its elasticity to keep the top rod 21 always in contact with the surface of the guide block 22, ensuring that the straight distance between the regulating pipe 2 and the vacuum pipe 13 remains stable and that the material conveying is not affected by negative pressure.

[0030] like Figures 1 to 11As shown, a synchronization frame 24 is further installed at the bottom of the pull rod 242. The center of the synchronization frame 24 is connected to the side wall of the top rod 21. A through groove 241 is opened on the synchronization frame 24, which is movably connected to the limiting rod 231. A fixing seat 243 is movably inserted into the side wall of the pull rod 242. The side wall of the fixing seat 243 is installed on the side wall of the air supply pipe 152 located on both sides. A secondary air outlet 252 is opened at the top of the air supply pipe 152 located on both sides. The synchronization frame 24 realizes the synchronous movement of the top rod 21 and the pull rod 242, ensuring that the adjustment action of the conical plug 251 and the adjusting pipe 2 is coordinated. The through groove 241 avoids interference between the synchronization frame 24 and the limiting rod 231 when moving. The fixing seat 243 fixes the position of the pull rod 242, ensuring that the pull rod 242 pushes the conical plug 251 stably. The secondary air outlet 252 cooperates with the main air outlet 213 to realize multi-position injection of raw materials, expand the raw material coverage area, and improve the utilization rate of the cooling roller.

[0031] The implementation principle of the vapor-phase feeding vacuum flaking machine of the present invention is as follows: First, before starting the equipment, the parameters are preset by the controller on the frame 11, the vacuum tube 13 is connected to the external vacuum system, and the inlet pipe 122 is connected to the gas phase raw material conveying system via the connecting flange 123. At the same time, it is ensured that the sealing plate 151 completely seals the notch 15 on the body 1 of the gas phase vacuum flaking machine to ensure the establishment of the vacuum environment. After starting, the controller first drives the vacuum system to run, and evacuates the internal cavity of the body 1 of the gas phase vacuum flaking machine through the vacuum tube 13. After the negative pressure in the cavity reaches the process requirements, the gas phase raw material conveying system is started. The gas phase raw material enters the inlet hood 12 through the inlet pipe 122. At this time, the limit seat 124 provides fixed support for the inlet pipe 122 to prevent the pipe from shifting due to airflow impact.

[0032] Subsequently, the controller starts the electric push rod 16, and the electric push rod 16 does not move in one direction, but drives the output end to slide back and forth continuously.

[0033] When the electric push rod 16 extends, its output end drives the three pairs of connecting plates 162 to move towards the center of the vapor phase vacuum slagging machine body 1 through the connecting frame 161. The connecting plates 162 then pull the sealing plate 151 to slide towards the center along the slide rod 154. The slide seat 153 at the bottom of the sealing plate 151 cooperates with the slide rod 154 to ensure smooth sliding, and the sealing plate 151 is always in close contact with the inner wall of the notch 15 to prevent vacuum leakage in the cavity. The three pairs of gas supply pipes 152 connected to the top of the sealing plate 151 move towards the center synchronously with the sealing plate 151. The gas supply pipe 152 located in the center drives the regulating pipe 2 to move. The top rod 21 at the bottom of the regulating pipe 2 moves down along the arc surface of the guide block 22 through the ball bearing 212 (the guide block 22 is low in the center and high at both ends), so that the straight distance between the regulating pipe 2 and the vacuum tube 13 remains unchanged, avoiding excessive negative pressure in the central area from sucking away the raw materials.

[0034] Simultaneously, the top rod 21 drives the synchronous frame 24 to move, and the synchronous frame 24 pulls the pull rod 242, causing the conical plugs 251 in the two side gas pipes 152 to move down in the conical through holes 25. Since the conical through holes 25 and the conical plugs 251 are compatible conical structures, the conical plugs 251 will reduce the gap with the inner wall of the conical through holes 25 when they move down. According to the principle of fluid mechanics, the reduction of the gap will increase the flow resistance of the gaseous raw material in the two side gas pipes 152, thereby reducing the speed at which the gaseous raw material is ejected from the secondary outlet 252 at the top of the two side gas pipes 152. However, the pressure of the gaseous raw material in the inlet hood 12 remains stable, which makes the speed at which the gaseous raw material is ejected from the main outlet 213 correspondingly increase. The faster ejection speed allows the gaseous raw material in the central area to more forcefully rush towards the surface of the cooling roller. Even if there is a certain negative pressure in the central area near the vacuum tube 13, the increased flow rate can ensure that the raw material quickly contacts the roller surface and condenses, avoiding being directly sucked away by the negative pressure.

[0035] The controller dynamically adjusts the reciprocating frequency and sliding stroke of the electric push rod 16 based on the real-time rotation speed of the cooling roller, the vacuum level inside the cavity, and the morphology of the agglomeration observed through the observation window 14. For example, when the rotation speed of the cooling roller increases, the reciprocating frequency of the electric push rod 16 increases synchronously to ensure that the dynamic coverage frequency of the raw material spraying matches the crystallization speed. When it is observed that the agglomeration on a certain side is too thin, the sliding stroke of the gas supply pipe 152 on that side is appropriately increased to prolong the spraying coverage time of the raw material in the corresponding area. Finally, the gaseous raw material is dynamically and uniformly covered by the main outlet 213 of the regulating pipe 2 and the auxiliary outlets 252 of the gas supply pipes 152 on both sides under the reciprocating drive of the electric push rod 16. After being condensed at low temperature by the cooling roller to form a continuous crystal layer, it is continuously scraped off by the scraper (not labeled, a conventional core component of the gas phase vacuum agglomerator body 1) fixed inside the cavity to form a sheet-like finished product. The vacuum pipe 13 continuously extracts the trace amount of non-condensable gas inside the cavity to maintain a stable vacuum environment, achieving continuous, uniform, and waste-free agglomeration production throughout the process.
