Description

Technical Field

[0001] This invention relates to the field of foam carrier ceramic processing technology, and in particular to a processing equipment and process for a foam ceramic filter for high-temperature alloy casting. Background Technology

[0002] Foam carrier ceramic filters are three-dimensional mesh structure ceramic products with alumina, zirconium oxide, or silicon carbide as the base material, and can be used to filter impurities.

[0003] Currently, when processing foam carrier ceramic filters, the foam carrier is first immersed in ceramic slurry, then the foam carrier is squeezed to expel excess coating, and the slurry is dried.

[0004] Regarding the aforementioned technologies, after the foam carrier is squeezed and dried, the slurry on the foam carrier ceramic carrier becomes more uniform, and the water evaporates. If the dried foam ceramic filter does not meet the preset weight, the foam carrier needs to be coated with slurry and dried again, which is inefficient. Summary of the Invention

[0005] To improve the processing efficiency of foam carriers, this application provides a processing equipment and process for foam ceramic filters used in high-temperature alloy casting.

[0006] In a first aspect, this application provides a processing equipment for foam ceramic filters used in high-temperature alloy casting, which adopts the following technical solution:

[0007] A processing equipment for foam ceramic filters used in high-temperature alloy casting includes a conveying assembly for conveying foam carriers. The processing equipment includes, from left to right, a feeding section, a transfer and drying section, and a coating and drying section. The coating and drying section includes a coating box, in which two spray guns for applying coating materials to the foam carriers are slidably connected. A drive roller is also rotating inside the coating box, and the drive roller has a receiving groove circumferentially opened to accommodate the foam carriers.

[0008] By adopting the above technical solution, the foam carrier soaked in slurry is placed on the feeding section. When the foam carrier passes through the coating box, the spray gun sprays out slurry to coat one side of the foam carrier. Then the foam carrier enters the transmission roller. By operating the transmission roller to rotate, the other side of the foam carrier faces upward. Then the spray gun coats the other side of the foam carrier with slurry again. If the weight of the foam carrier after drying does not meet the preset weight, the foam carrier can be coated a second time in the coating box. Material can be coated on both sides of the foam carrier, and the coating uniformity is good and the efficiency is high.

[0009] Optionally, four sprockets are rotatably connected inside the coating box, and the four sprockets are respectively arranged at the four corners of the coating box. A chain is installed inside the coating box, and the chain meshes with the outside of the four sprockets. Both spray guns are fixedly connected to the outside of the chain.

[0010] By adopting the above technical solution, one of the sprockets is rotated to drive the chain to move, which in turn drives the other sprockets to rotate, thus moving the two spray guns. The structure is simple and the transmission is convenient.

[0011] Optionally, the system also includes a frame. The conveying assembly includes a first conveyor belt and a second conveyor belt, both of which are mounted on the frame. A drive roller is horizontally rotatably connected to the frame and is located between the first and second conveyor belts. The height of the second conveyor belt is lower than that of the first conveyor belt. A guide plate is also inclinedly mounted on the frame and is located on the side of the second conveyor belt closer to the drive roller.

[0012] By adopting the above technical solution, as the foam carrier is conveyed, the foam carrier located on conveyor belt one enters the receiving tank. As the drive roller rotates, it drives the foam carrier to rotate. When it rotates to the direction close to conveyor belt two, the foam carrier moves along the inclined angle of the bottom wall of the receiving tank. After moving to the upper end of the guide plate, it moves towards the direction close to conveyor belt two. The structure is simple and the conveying is convenient, and the foam carrier is not coated with materials for secondary coating.

[0013] Optionally, one end of the transmission roller in the length direction has a bevel gear, and a sprocket is rotatably connected inside the coating box. The sprocket meshes with the chain, and the lower end of the sprocket is coaxially fixedly connected to a bevel gear. The bevel gear meshes with the bevel gear.

[0014] By adopting the above technical solution, as the chain moves, it drives the second sprocket to rotate, which in turn drives the second bevel gear to rotate, which in turn drives the first bevel gear to rotate, which in turn drives the transmission roller to rotate. While coating the foam carrier, the transmission roller can be driven to rotate. The structure is simple, the transmission is convenient, the required transmission structure is small, and the efficiency is high.

[0015] Optionally, the conveying assembly includes a feeding rack with a feeding conveyor belt located at the feeding section. A plurality of extrusion rollers for extruding the foam carrier are movably connected to the upper end of the feeding rack. A detection conveyor platform is provided between the feeding rack and the transfer and drying section. A detection conveyor belt is provided on the detection conveyor platform, and a weighing device for weighing the foam carrier is provided on the detection conveyor platform. A push cylinder is horizontally arranged on the detection conveyor platform, and a push plate is provided on the piston rod of the push cylinder. A conveyor platform is provided on one side of the detection conveyor platform along its length, and the piston rod of the push cylinder is oriented towards the conveyor platform.

[0016] By adopting the above technical solution, the foam carrier moves with the feed conveyor belt. When it reaches the extrusion roller, part of the foam carrier is squeezed out under the action of the extrusion roller. As the foam carrier is moved to the detection conveyor, its weight is measured. If the weight meets the set threshold, the foam carrier is moved to the next station. If the weight does not meet the set threshold, the piston rod of the push cylinder is extended to push the foam carrier to the conveyor, and the foam carrier is transported to the previous station for re-coating.

[0017] Optionally, the transfer and drying section includes a transfer conveyor belt and a drying box. The drying box is located above the transfer conveyor belt. The transfer conveyor belt has several through holes at equal intervals, and the drying box has several resistance wires arranged inside.

[0018] By adopting the above technical solution, as the conveyor belt transports the foam carrier, electricity is passed into the resistance wire during the transportation process, and the resistance wire dissipates heat, thereby drying the foam carrier and improving its strength. This method is highly efficient.

[0019] Optionally, the coating and drying section further includes a second drying chamber, and the conveying assembly further includes a discharge conveyor belt. The second drying chamber is located at the upper end of the discharge conveyor belt, and several resistance wires are also provided inside the second drying chamber.

[0020] By adopting the above technical solution, after the other side of the foam carrier is coated, it is dried in the second drying oven, thereby improving the strength of the foam carrier and achieving high efficiency.

[0021] Secondly, this application provides a processing technology for a foam ceramic filter used in high-temperature alloy casting.

[0022] A processing method for a foam ceramic filter used in high-temperature alloy casting includes the following steps:

[0023] S1: Place the foam carriers that have been coated with slurry onto the feed conveyor belt in sequence. As the foam carriers move, they are squeezed by the extrusion rollers to expel the excess foam carriers.

[0024] S2: The foam carrier is moved to the detection conveyor belt for weighing; if the weight of the foam carrier is within the preset range, the foam carrier is manipulated to continue moving; if the weight of the foam carrier is not within the preset range, the piston rod of the push cylinder is manipulated to extend and push the foam carrier to the conveyor table for re-coating the foam carrier.

[0025] S3: Foam carriers within the preset range are moved onto the transfer conveyor belt, and the drying box dries the foam carriers on the transfer conveyor belt.

[0026] S4: After drying, the foam carrier is moved to conveyor belt 1. After spraying one side of the foam carrier, the foam carrier is moved into the transmission roller.

[0027] S5: The foam carrier moves from the transmission roller to the second conveyor belt, and the other side of the foam carrier is sprayed.

[0028] S6: The foam carrier is discharged after being dried twice in the drying box.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. Place the foam carrier soaked in slurry on the feeding section. When the foam carrier passes through the coating box, the spray gun sprays slurry to coat one side of the foam carrier. Then the foam carrier enters the transmission roller. By operating the transmission roller to rotate, the other side of the foam carrier faces upward. Then the spray gun coats the other side of the foam carrier with slurry again. If the weight of the foam carrier after drying does not meet the preset weight, the foam carrier can be coated a second time in the coating box. Material can be coated on both sides of the foam carrier. The coating uniformity is good and the efficiency is high.

[0031] 2. As the chain moves, it drives the second sprocket to rotate, which in turn drives the second bevel gear to rotate, which in turn drives the first bevel gear to rotate, which in turn drives the transmission roller to rotate. While coating the foam carrier, the transmission roller can be driven to rotate. The structure is simple, the transmission is convenient, the required transmission structure is small, and the efficiency is high. Attached Figure Description

[0036] The present application will be further described in detail below with reference to all the accompanying drawings.

[0037] This application discloses a processing equipment for foam ceramic filters used in high-temperature alloy casting.

[0038] Reference Figure 1 and Figure 2 A high-temperature alloy casting foam ceramic filter processing equipment includes a conveying assembly for conveying foam carriers. From left to right, the processing equipment includes a feeding section 1, a transfer and drying section 2, and a coating and drying section 3. The coating and drying section 3 includes a coating box 31, within which two spray guns 32 for coating materials onto the foam carrier are slidably connected. A drive roller 33 also rotates within the coating box 31, and the drive roller 33 has a circumferentially oriented receiving groove 331 for accommodating the foam carrier. The foam carrier, impregnated with slurry, is placed on the feeding section 1, and the foam... When the foam carrier passes through the coating box 31, the spray gun 32 sprays out slurry to coat one side of the foam carrier. Then the foam carrier enters the transmission roller 33. By operating the transmission roller 33 to rotate, the other side of the foam carrier faces upward. Then the spray gun 32 coats the other side of the foam carrier with slurry again. If the weight of the foam carrier after drying does not meet the preset weight, the foam carrier can be coated a second time in the coating box 31. Material can be coated on both sides of the foam carrier, and the coating uniformity is good and the efficiency is high.

[0039] Reference Figure 1 and Figure 2The conveying assembly includes a feeding rack 11, on which a feeding conveyor belt 12 is mounted. The feeding conveyor belt 12 is located in the feeding section 1. Several extrusion rollers 13 for extruding the foam carrier are movably connected to the upper end of the feeding rack 11. A detection conveyor table 14 is provided between the feeding rack 11 and the transfer and drying section 2. A detection conveyor belt 15 is mounted on the detection conveyor table 14. A weighing device 16 for weighing the foam carrier is mounted on the detection conveyor table 14. A push cylinder 17 is horizontally mounted on the detection conveyor table 14. A push plate 18 is mounted on the piston rod of the push cylinder 17. A conveyor table 19 is provided on one side of the detection conveyor table 14 along its length. The piston rod of the push cylinder 17 faces... The direction setting of the conveyor table 19: First, after the foam carrier is fully coated with slurry, the foam carrier carrying ceramics is placed at the upper end of the feed conveyor belt 12. The foam carrier moves with the feed conveyor belt 12. When it moves to the extrusion roller 13, part of the foam carrier is squeezed out under the action of the extrusion roller 13. As the foam carrier is moved to the detection conveyor table 14, the weight is measured on the detection conveyor table 14. If the weight is within the set threshold range, the foam carrier is moved to the next station. If the weight is not within the set threshold range, the piston rod of the push cylinder 17 is extended to push the foam carrier to the conveyor table 19 and transport the foam carrier to the previous station for re-coating.

[0040] Referring to the figure, the transfer and drying unit 2 includes a transfer conveyor belt and a drying box 21. The drying box 21 is located above the transfer conveyor belt. Several through holes are evenly spaced on the transfer conveyor belt. Several resistance wires are arranged inside the drying box 21. As the transfer conveyor belt transports the foam carrier, electricity is passed into the resistance wires during the transport process, and the resistance wires dissipate heat, thereby drying the foam carrier and improving the strength of the foam carrier. The efficiency is relatively high.

[0041] Referring to the figure, the processing equipment also includes a frame 4, and the conveying components include a first conveyor belt 41 and a second conveyor belt 42. Both the first conveyor belt 41 and the second conveyor belt 42 are mounted on the frame 4. A drive roller 33 is horizontally rotatably connected to the frame 4 and is located between the first conveyor belt 41 and the second conveyor belt 42. The height of the second conveyor belt 42 is lower than the height of the first conveyor belt 41. A guide plate 43 is also inclinedly mounted on the frame 4 and is located on the side of the second conveyor belt 42 near the drive roller 33. The coating box 31 is located above the first conveyor belt 41, the second conveyor belt 42 and the drive roller 33.

[0042] Reference Figure 2 and Figure 3Four sprockets 34 are rotatably connected inside the coating box 31, and are respectively located at the four corners of the coating box 31. A chain 35 is installed inside the coating box 31, and the chain 35 is engaged with the outside of the four sprockets 34. Two spray guns 32 are fixedly connected to the outside of the chain 35. As the foam carrier moves, when it moves below the spray gun 32, if the weight of the foam carrier is less than the standard value according to the previously measured weight of the foam carrier, the spray gun 32 is operated to spray out the foam carrier. The foam carrier sprayed out of the spray gun 32 falls to the upper end of the foam carrier coating box 31. A drive motor is installed at the upper end of the coating box 31, and the output shaft of the drive motor is coaxially fixedly connected to one of the sprockets 34. By operating the output shaft of the drive motor to rotate, one of the sprockets is driven to rotate, which in turn drives the chain 35 to move, which in turn drives the spray gun 32 to move. As the spray gun 32 moves, the foam carrier is coated on one side of the foam carrier.

[0043] Reference Figure 2 and Figure 3 One end of the drive roller 33 along its length has a bevel gear 332. A sprocket 36 is rotatably connected inside the coating box 31, meshing with the chain 35. A bevel gear 361 is coaxially fixed to the lower end of the sprocket 36, meshing with the bevel gear 332. As the chain 35 moves, it drives the sprocket 36 to rotate, which in turn drives the bevel gear 361, which in turn drives the bevel gear 332, ultimately rotating the drive roller 33. This allows the drive roller 33 to rotate while simultaneously coating the foam carrier. The structure is simple, the transmission is convenient, it requires fewer transmission components, and it is highly efficient.

[0044] Reference Figure 2 and Figure 3 After the foam carrier is coated, it moves towards the drive roller 33 under the drive of the first conveyor belt 41. The foam carrier on the first conveyor belt 41 enters the receiving tank 331. As the drive roller 33 rotates, it drives the foam carrier to rotate. When it rotates towards the second conveyor belt 42, the foam carrier moves along the inclined angle of the bottom wall of the receiving tank 331. After moving to the upper end of the guide plate 43, it moves towards the second conveyor belt 42. The structure is simple and the conveying is convenient.

[0045] Reference Figure 2 and Figure 3 As the chain 35 moves, the spray gun 32 moves above the second conveyor belt 42. As the foam carrier moves above the second conveyor belt 42 and below the spray gun 32, the spray gun 32 is manipulated to spray out material. The spray gun 32 moves along the width of the second conveyor belt 42 to coat the other side of the foam carrier with slurry.

[0046] Reference Figure 2and Figure 3 The coating and drying section 3 also includes a second drying chamber 37, and the conveying assembly includes a discharge conveyor belt 5. The second drying chamber 37 is located at the upper end of the discharge conveyor belt 5. Several resistance wires are also installed inside the second drying chamber 37. By conveying the foam carrier, the material on the foam carrier is dried, further improving the strength of the material. As the foam carrier continues to be conveyed, it moves to the outside of the second drying chamber 37, completing the processing of the material.

[0047] This application also provides a processing technology for a foam ceramic filter for high-temperature alloy casting.

[0048] A processing method for a foam ceramic filter used in high-temperature alloy casting includes the following steps:

[0049] S1: The foam carriers that have been coated with slurry are placed sequentially on the feed conveyor belt 12. As the foam carriers move, they are squeezed by the extrusion rollers 13 to expel the excess foam carriers.

[0050] S2: The foam carrier is moved to the detection conveyor belt 15 for weighing; if the weight of the foam carrier is within the preset range, the foam carrier is manipulated to continue moving; if the weight of the foam carrier is not within the preset range, the piston rod of the push cylinder 17 is manipulated to extend and push the foam carrier to the conveyor table 19, so that the foam carrier can be re-coated with slurry.

[0051] S3: Foam carriers within the preset range are moved onto the transfer conveyor belt, and drying box 21 dries the foam carriers on the transfer conveyor belt;

[0052] S4: The dried foam carrier moves to the conveyor belt 41, and after spraying one side of the foam carrier, the foam carrier moves into the transmission roller 33.

[0053] S5: The foam carrier moves from the transmission roller 33 to the conveyor belt 42, and the other side of the foam carrier is sprayed.

[0054] S6: The foam carrier is discharged after being dried twice in drying oven 37.

[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
