Description

Technical Field

[0001] This invention relates to the field of cuprous oxide synthesis material technology, specifically to an intelligent anti-oxidation sealed conveying device for cuprous oxide synthesis materials. Background Technology

[0002] As is well known, cuprous oxide, an important inorganic chemical product, is a red or purplish-red powder widely used in antifouling paints for ships, pesticides, electronic materials, catalysts and other fields. The materials produced during its synthesis (such as cuprous oxide semi-finished products and intermediate powders) have extremely strong oxidizability. Once exposed to air or high temperature, they are easily oxidized to copper oxide, resulting in a decrease in product purity, a blackening of color and economic losses.

[0003] A search revealed that Chinese Patent Publication No. CN217971637U discloses a positive pressure conveying system for cuprous oxide, comprising a feeding hopper and an extraction chamber. The bottom flange of the feeding hopper is connected to the extraction chamber. The system also includes a conveying pipe with a Roots blower connected to its left end. The upper left end of the conveying pipe is flanged to the bottom end of the extraction chamber, and a distribution pipe is connected to the right end of the conveying pipe. The bottom end of the distribution pipe extends into the upper left interior of a storage hopper, which has a discharge port at its bottom. This positive pressure conveying system for cuprous oxide is equipped with a cam. The air blown out through the distribution pipe drives the fan blades to rotate, which in turn drives a rotating rod. A pulley then drives the first rotating rod to rotate the cam, causing the cam to beat the filter screen. This prevents dust from accumulating on the filter screen after long-term use, improving exhaust efficiency and extending the filter screen's lifespan.

[0004] Although the above technical solutions solve the problems of poor exhaust effect due to filter clogging after long-term use of pneumatic conveying and the short service life of the filter, the cuprous oxide synthetic material is a fine powder with a high specific gravity. The fine powder is easily adsorbed on the inner wall of the pipe, and the material is prone to oxidation and agglomeration. After agglomeration, it is even more easy to adhere and accumulate. Since most pipes are closed, the adhered material is difficult to fall off naturally. Once the material in the pneumatic conveying system is damp and soft and agglomerated, it is very easy to stick to the pipe and clog the pipe, which is very troublesome to clean. In order to solve the above problems, an intelligent anti-oxidation closed conveying device for cuprous oxide synthetic material is needed. Summary of the Invention

[0005] To overcome the problem that existing intelligent anti-oxidation sealed conveying devices for cuprous oxide synthetic materials are prone to pipe sticking and blockage when the material is damp, soft, or clumps together, making cleaning very troublesome, this invention provides an intelligent anti-oxidation sealed conveying device for cuprous oxide synthetic materials that can clean the inner wall of the conveying pipe during transportation.

[0008] Furthermore, the scraping assembly includes a fixing ring, which is fixedly disposed on the top of the threaded plate and sleeved on the outside of the protective tube. Mounting plates are fixedly disposed on both sides of the fixing ring, and at least three sliding grooves are formed on the mounting plates. A slider is slidably disposed in the sliding grooves, and a moving ring is fixedly disposed on the side of the slider. A silicone plate is fixedly disposed on the outer surface of the moving ring, and the silicone plate is in contact with the inner wall of the conveying frame. A limiting post is fixedly disposed in the sliding groove, and the slider is slidably disposed with the limiting post. A spring is sleeved on the limiting post, and the spring is fixedly disposed with the inner wall of the sliding groove and the slider.

[0009] Furthermore, a rotating ring is rotatably disposed within the mounting plate, a rotating rod is fixedly disposed on the side of the rotating ring, a cleaning ring is fixedly disposed on the side of the rotating rod, the inner surface of the cleaning ring is adapted to the outer surface of the silicone plate, a cleaning plate is fixedly disposed at the bottom of the rotating rod, the cleaning plate is in contact with the side of the mounting plate, and bristles are fixedly disposed on the rotating rod, the bottom of the bristles being in contact with the side of the moving ring.

[0010] In a further embodiment, the bottom of the conveyor plate is provided with an installation groove, in which a second motor is fixedly installed. The output shaft of the second motor is connected to a first gear via a key. A second gear is fixedly installed on the side of the rotating ring. The first gear is located at the bottom of the second gear, and the second gear meshes with the first gear. A shield is fixedly installed on the top of the conveyor plate, which covers the first gear and the second gear.

[0011] Based on the aforementioned scheme, an air extraction pipe is fixedly installed on the side of the conveying frame, the air extraction pipe is connected to the inside of the conveying frame, a pressure gauge is fixedly installed on the top of the air extraction pipe, and a container with a built-in air extraction pump is fixedly installed at the other end of the air extraction pipe.

[0012] Furthermore, based on the aforementioned scheme, the quantitative component includes a quantitative tube, which is fixedly installed to the receiving frame via a fixed flange. A reinforcing rib is fixedly installed between the quantitative tube and the fixed flange. A support frame is fixedly installed inside the mounting frame, and the support frame is fixedly installed to the quantitative tube.

[0013] Furthermore, based on the aforementioned scheme, a rotating block is fixedly installed on one side of the bottom of the quantitative tube, a cover plate is rotatably installed on the rotating block, a sealing gasket is fixedly installed on the cover plate, and the cover plate is adapted to the bottom of the quantitative tube through the sealing gasket.

[0014] Furthermore, based on the aforementioned solution, a fixing plate is fixedly installed at the bottom of the mounting frame, a hydraulic rod is fixedly installed on the fixing plate, a bonding plate is fixedly installed on the output shaft of the hydraulic rod, a second inclined surface is opened on the bonding plate, a soft rubber pad is fixedly installed on the top of the bonding plate, and the bonding plate, in conjunction with the soft rubber pad, is bonded to the bottom of the cover plate.

[0015] Furthermore, based on the aforementioned solution, an operating platform is fixedly installed on the side of the mounting frame, and a display screen, instruments, alarm lights, and operating buttons are fixedly installed on the operating platform.

[0016] This intelligent, anti-oxidation, sealed conveying device for cuprous oxide synthesis materials: 1. The device adopts a fully enclosed vacuum structure. The receiving frame, sealing plate, conveying pipe and conveying frame form a closed channel without any openings. With the help of the air extraction pipe and air extraction pump, the conveying chamber can be evacuated to completely isolate the air from the material. This prevents the red or purplish-red cuprous oxide from being oxidized into black copper oxide, eliminates the problem of reduced material purity and quality failure, and reduces economic losses in production.

[0017] 2. The reciprocating screw drives the conveyor plate and the scraping component to reciprocate synchronously. The silicone plate of the scraping component is always in close contact with the inner wall of the conveyor frame under the elasticity of the spring. During the conveying process, it scrapes off the adhering fine powder and clumps of materials in real time. With the pushing action of the conveyor plate, the material is kept in a flowing state and will not accumulate and clump on the pipe wall, thus fundamentally eliminating pipe sticking and blockage and ensuring the continuous smooth flow of the conveying channel.

[0018] 3. The device is equipped with a conveying and self-cleaning linkage structure. The second motor drives the rotating ring, cleaning ring and brush to rotate synchronously through the gear set, so as to perform secondary flexible cleaning of the silicone plate, moving ring and residual materials on the pipe wall. There is no need to disassemble the pipeline or stop the machine for manual operation. The conveying and cleaning are completed at the same time, which greatly reduces the difficulty of pipeline maintenance and labor costs.

[0019] 4. The metering component drives the cover plate to open and close via a hydraulic rod, which can precisely control the amount and rhythm of material feeding, realize the quantitative and closed conveying of cuprous oxide synthesis materials, avoid overfeeding or underfeeding, perfectly adapt to the precise feeding requirements of the synthesis process, and improve the process stability of subsequent synthesis steps.

[0020] 5. The device is equipped with a triple protection structure consisting of a protective pipe, a baffle plate, and a shield, which respectively cover the reciprocating lead screw, the transmission opening, and the gear assembly, completely isolating the material from the transmission components. This prevents fine powder from entering the gaps between the lead screw and gears, causing jamming and wear, significantly reducing the probability of equipment failure, and extending the service life of the core transmission components.

[0021] 6. The scraping component adopts a flexible and adaptive structure consisting of a slider, a limiting post, and a spring. The moving ring and the silicone plate can automatically adjust their fit according to the deformation of the tube wall. Even if there are local lumps or slight deformations on the tube wall, it can achieve scraping without dead angles. Combined with the flexible cleaning of the cleaning ring and bristles, it completely solves the problem of residue cleaning by traditional fixed scrapers.

[0022] 7. Equipped with an intelligent control panel featuring a display screen, instruments, alarm lights, and control buttons, it can monitor the vacuum level of the cavity, material conveying status, and equipment operating parameters in real time. In the event of abnormalities such as vacuum leakage, pipe blockage, or motor failure, it will immediately issue an audible and visual warning, facilitating quick handling by operators, preventing the escalation of the fault, and improving the intelligence and safety of operations.

[0023] 8. Both the conveyor plate and the bonding plate adopt a sloping structure design, which effectively reduces the material pushing resistance and allows the powder material to be conveyed forward more smoothly. At the same time, the sealing gasket and soft rubber gasket improve the sealing performance of the components, prevent material leakage, and further improve the efficiency and stability of the closed conveying.

The triple protection structure completely separates the transmission components from the conveying cavity, preventing cuprous oxide powder from entering the gap between the lead screw and gears, preventing jamming and wear of the transmission components, and ensuring long-term stable operation of the equipment.

[0045] Then, refer to Figure 10 In this embodiment, the slider 22 of the scraping component 11 slides along the limiting post 25, and the spring 26 continuously applies an elastic thrust to the slider 22. The moving ring 23 and the silicone plate 24 are always in contact with the inner wall of the conveying frame 7 under the action of the spring 26. The silicone plate 24 can automatically adjust its contact position according to the local deformation of the inner wall of the conveying frame 7, so as to achieve scraping without dead corners on the inner wall of the conveying frame 7 and avoid the adhesion and accumulation of powder materials.

[0046] Secondly, see Figure 9 In this embodiment, the second motor 33 drives the rotating ring 27 to rotate through the meshing of the first gear 34 and the second gear 35. The rotating ring 27 drives the rotating rod 28, the cleaning ring 29, the cleaning plate 30 and the brush bristles 31 to rotate synchronously. The cleaning ring 29 wipes the surface of the silicone plate 24, the cleaning plate 30 wipes the surface of the mounting plate 20, and the brush bristles 31 wipes the surface of the moving ring 23. The self-cleaning action is completed synchronously during the conveying process, without the need to disassemble the pipeline for cleaning.

[0047] Again, see Figure 7 In this embodiment, the conveying plate 12 is fixed together with the baffle plate 14 and the threaded plate 10 through the connecting frame 15. The reciprocating screw 9 rotates to drive the threaded plate 10 to move back and forth, thereby driving the conveying plate 12 and the scraping component 11 to move back and forth synchronously. The conveying plate 12 pushes the material to move, and the scraping component 11 scrapes the material adhering to the pipe wall. The conveying and cleaning actions are carried out simultaneously.

[0048] In addition, see Figure 13In this embodiment, the quantitative tube 40 is connected to the receiving frame 1 through the fixed flange 41, and the hydraulic rod 48 drives the bonding plate 49 to move vertically, controlling the opening and closing angle and opening and closing time of the cover plate 45, accurately controlling the amount of cuprous oxide material to be fed, realizing quantitative and closed conveying, and avoiding excessive or insufficient material supply.

[0049] In addition, see Figure 3 In this embodiment, the air extraction pipe 37 connects the air pump inside the conveying frame 7 and the holding tank 39. The air pump operates to extract air from inside the conveying frame 7 to form a vacuum environment. The pressure gauge 38 monitors the vacuum level in real time. With the intelligent monitoring of the operating table 52, it ensures that the conveying cavity is always in a sealed vacuum state, isolating air from contact with materials.

[0050] In addition, see Figure 12 In this embodiment, the sealing gasket 46 on the cover plate 45 and the soft rubber gasket 51 on the bonding plate 49 respectively improve the sealing performance between the cover plate 45 and the metering tube 40 and between the bonding plate 49 and the cover plate 45, preventing material leakage from gaps and preventing external air from entering the conveying cavity, thus ensuring a sealed and anti-oxidation effect.

[0051] Finally, see Figure 13 In this embodiment, the first inclined surface 16 of the conveying plate 12 and the second inclined surface 50 of the bonding plate 49 reduce the material pushing resistance and the opening and closing resistance of the cover plate 45, respectively, making the material conveying smoother, the opening and closing of the cover plate 45 more stable, and improving the overall operating efficiency of the device.

[0052] Working principle: When using this intelligent anti-oxidation sealed conveying device for cuprous oxide synthesis materials, first place the device at the designated position in the cuprous oxide synthesis production station. Then, connect the receiving frame 1 to the discharge port of the upstream synthesis equipment through the connecting flange 3 on the top of the sealing plate 2 to complete the sealing installation of the feeding end of the device. Next, connect the discharge end of the conveying frame 7 to the feeding port of the downstream processing equipment to complete the sealing installation of the discharge end of the device. Check the sealing of each connection part of the device to ensure that the receiving frame 1, the metering tube 40, the conveying tube 6, and the conveying frame 7 form a complete sealed conveying channel without any air leakage gaps.

[0053] After the device is installed, the air pump inside the holding tank 39 is started by operating button 56 on the control panel 52. The air pump operates to extract air from the inside of the conveying frame 7 through the air extraction pipe 37, and simultaneously extracts air from the inside of the conveying pipe 6, the metering pipe 40, and the receiving frame 1, so that a vacuum environment is formed inside the entire sealed conveying channel. During the air extraction process, the pressure gauge 38 monitors the air pressure value inside the air extraction pipe 37 in real time and transmits the air pressure data to the display screen 53 and instrument 54 on the control panel 52. The operator observes the vacuum degree inside the conveying cavity through the display screen 53 and instrument 54. When the vacuum degree reaches the required value for the process, the air pump is stopped by operating button 56, and the vacuum treatment of the conveying cavity is completed.

[0054] After vacuum treatment, a feed signal is sent to the upstream synthesis equipment. The cuprous oxide synthesis material enters the receiving frame 1 through the discharge port. The material flows downward under gravity and enters the metering tube 40 at the bottom of the receiving frame 1. The material accumulates inside the metering tube 40. After the preset material amount is reached, the hydraulic rod 48 is activated by the operation button 56 on the control panel 52. The output axis of the hydraulic rod 48 extends upward, driving the bonding plate 49 to move upward. The soft rubber pad 51 on the top of the bonding plate 49 is attached to the bottom of the cover plate 45. The bonding plate 49 continues to move upward, pushing the cover plate 45 to flip upward around the rotating block 44. The cover plate 45 separates from the bottom opening of the metering tube 40. The material inside the metering tube 40 flows downward under gravity and enters the conveying frame 7 through the conveying pipe 6.

[0055] The operator adjusts the extension length of the hydraulic rod 48 output shaft according to process requirements, controls the opening and closing angle of the cover plate 45, and thus controls the material feeding speed. At the same time, the operator controls the running time of the hydraulic rod 48 and the opening and closing duration of the cover plate 45 to achieve quantitative material feeding. When the material feeding reaches the preset value, the operator controls the output shaft of the hydraulic rod 48 to retract downward through the operating button 56, which drives the bonding plate 49 to move downward. Under its own gravity, the cover plate 45 flips downward around the rotating block 44, and the sealing gasket 46 on the top of the cover plate 45 re-fits with the bottom opening of the quantitative tube 40, sealing the bottom of the quantitative tube 40 and stopping the material feeding. The reinforcing rib 42 increases the connection strength between the fixed flange 41 and the quantitative tube 40, and the support frame 43 supports the quantitative tube 40 to prevent the quantitative tube 40 from shaking under the impact of the material and ensure the stability of quantitative feeding.

[0056] After the material enters the conveying frame 7, the first motor 18 is started by the operation button 56 on the control panel 52. The operation of the first motor 18 drives the output shaft to rotate. The output shaft of the first motor 18 drives the reciprocating screw 9 to rotate synchronously through a key connection. The reciprocating screw 9 and the threaded plate 10 are threadedly matched. The rotation of the reciprocating screw 9 drives the threaded plate 10 to move vertically back and forth along the opening at the top of the protective tube 13. The movement of the threaded plate 10 drives the fixed ring 19 to move synchronously. The fixed ring 19 drives the mounting plates 20, the moving ring 23, and the silicone plate 24 on both sides to move vertically back and forth. Under the elastic thrust of the spring 26, the silicone plate 24 always adheres to the inner wall of the conveying frame 7. During the movement of the silicone plate 24, it scrapes off the cuprous oxide powder and agglomerated material adhering to the inner wall of the conveying frame 7, preventing the material from accumulating and sticking to the tube wall.

[0057] As the threaded plate 10 moves, it drives the baffles 14 on both sides to slide vertically along the inner wall of the conveying frame 7. The baffles 14 always block the opening at the top of the protective tube 13 to prevent material from entering the protective tube 13 and contacting the reciprocating screw 9. The movement of the baffles 14 drives the conveying plate 12 to move vertically and reciprocally in sync through the connecting frame 15. During the movement of the conveying plate 12, it pushes the material inside the conveying frame 7 towards the discharge direction. The first inclined surface 16 at the bottom of the conveying plate 12 reduces the contact resistance with the material, making the material push smoother. Under the pushing action of the conveying plate 12 and the scraping action of the silicone plate 24, the material remains in a flowing state and moves smoothly towards the discharge end of the conveying frame 7, completing the closed conveying of the material.

[0058] During material conveying, the second motor 33 is started via the operation button 56 on the control panel 52. The operation of the second motor 33 drives the output shaft to rotate. The output shaft of the second motor 33 drives the first gear 34 to rotate via a key connection. The first gear 34 meshes with the second gear 35. The rotation of the first gear 34 drives the second gear 35 to rotate. The rotation of the second gear 35 drives the rotating ring 27 to rotate circumferentially along the mounting plate 20. The rotation of the rotating ring 27 drives multiple sets of rotating rods 28 to rotate synchronously. The rotation of the rotating rods 28 drives the cleaning ring 29, the cleaning plate 30, and the brush bristles. 31 rotates synchronously. During the rotation of the cleaning ring 29, it wipes the outer surface of the silicone plate 24 and scrapes off the material residue adhering to the surface of the silicone plate 24. During the rotation of the cleaning plate 30, it wipes the outer surface of the mounting plate 20 and removes the material dust from the surface of the mounting plate 20. During the rotation of the brush 31, it wipes the inner side wall of the moving ring 23 and cleans the material adhering to the surface of the moving ring 23, thereby realizing the real-time self-cleaning of the scraping component 11. The shield 36 always covers the first gear 34 and the second gear 35 to prevent material from entering the gear meshing gap and ensure smooth gear transmission.

[0059] During operation, the display screen 53 on the control panel 52 displays real-time operating parameters such as the vacuum level of the conveying chamber, the speed of the first motor 18, the speed of the second motor 33, and the stroke of the hydraulic rod 48. The instrument 54 displays the chamber air pressure data intuitively. Once a vacuum leak occurs in the conveying chamber, the pressure gauge 38 detects that the air pressure value exceeds the process range, and the alarm light 55 on the control panel 52 immediately emits an audible and visual alarm to remind the operator to check the sealing parts in time. Once material blockage occurs, the pushing resistance of the conveying plate 12 increases, and the equipment operating current is abnormal. The alarm light 55 simultaneously emits an audible and visual alarm. The operator can adjust the equipment operating parameters in time through the operation button 56, troubleshoot the fault, and prevent the fault from escalating.

[0060] When conveying different batches and amounts of cuprous oxide synthetic materials, the operating parameters of the hydraulic rod 48 can be reset through the control panel 52, and the opening and closing angle and opening and closing time of the cover plate 45 can be adjusted to precisely control the material feeding amount and adapt to different process conveying requirements. After the equipment has been running for a long time, there is no need to disassemble the conveying frame 7 and the pipe. The scraping component 11 and the self-cleaning component continue to run to clean the pipe wall and the scraping component, keeping the conveying channel unobstructed.

[0061] After the material conveying operation is completed, the second motor 33 and the first motor 18 are turned off in sequence by the operation button 56 on the control panel 52 to stop the conveying and self-cleaning action. Then, the hydraulic rod 48 is controlled to reset so that the cover plate 45 is kept closed. Finally, the vacuum pump can be started as needed to maintain the vacuum of the conveying chamber for direct use in the next conveying operation. If equipment maintenance is required, all equipment operation can be stopped by the control panel 52, the vacuum inside the conveying chamber can be slowly released, and then subsequent maintenance operations can be carried out.

[0062] During operation, the fixed ring 19 moves synchronously with the threaded plate 10 to ensure that the scraping component 11 and the conveying plate 12 move in unison. The slider 22 slides stably along the limiting post 25, and the spring 26 continuously provides elastic thrust, so that the silicone plate 24 always adheres to the inner wall of the conveying frame 7. Even if there is local caking or slight deformation on the inner wall of the conveying frame 7, the silicone plate 24 can adaptively adjust its contact position to achieve scraping without dead angles. The linkage rotation of the rotating ring 27, rotating rod 28, cleaning ring 29, cleaning plate 30, and brush bristles 31 thoroughly cleans the material residue on the surface of each component of the scraping component 11, preventing the material residue from caking and affecting the subsequent scraping effect. The vacuum pump continuously maintains the vacuum of the conveying chamber, completely isolating the air from contact with the cuprous oxide material, preventing the material from being oxidized to copper oxide, and ensuring the purity and quality of the material.

[0063] The triple protection structure continues to function effectively: the protective tube 13 isolates the reciprocating screw 9 from contact with the material; the baffle plate 14 isolates the opening of the protective tube 13 from contact with the material; and the baffle cover 36 isolates the gear assembly from contact with the material. This prevents fine powder from entering the gaps in the transmission components, avoids jamming and wear of the transmission components, and extends the service life of the core components of the equipment. The precise control of the quantitative component 5 ensures that the material conveying volume matches the requirements of the synthesis process, improving the process stability of subsequent synthesis steps. The intelligent monitoring and audible and visual alarms of the operating console 52 enable real-time control of the equipment's operating status, improving operational safety and intelligence, reducing manual inspection workload, and lowering production labor costs.

[0064] The entire conveying process is conducted in a closed vacuum environment with no openings or air contact. Material conveying, pipe wall scraping, component self-cleaning, quantitative feeding, and intelligent monitoring are completed simultaneously. There is no need to stop the machine for manual pipe cleaning or disassemble the equipment to replace parts. This effectively solves the problems of easy oxidation, easy pipe sticking, easy pipe blockage, and troublesome cleaning of cuprous oxide powder materials, ensuring the stability, continuity, and safety of the material conveying process and meeting the closed oxidation-proof conveying process requirements of cuprous oxide synthesis production.
