Description

Technical Field

[0001] This utility model relates to the field of alumina catalyst support production technology, and in particular to an extrusion molding device for alumina catalyst supports. Background Technology

[0002] Alumina catalysts are catalysts with alumina as a support or main component. Alumina possesses high chemical stability, large specific surface area, porous structure, good acid-base properties, and renewability, thus it is widely used as a catalyst or catalyst support. As a catalyst support, alumina has extensive applications in petrochemicals, fine chemicals, and environmental engineering. Extrusion molding is a key step in the preparation of alumina catalysts. Its main purpose is to adjust the pore structure, specific surface area, and mechanical strength of the catalyst through extrusion molding, thereby improving the catalyst's stability and service life.

[0003] Existing technology CN222156786U discloses an alumina catalyst carrier forming device, including a base, a gantry frame fixedly connected to the upper end face of the base, an electric push rod installed on the upper end face of the gantry frame, the output end of the electric push rod extending to the lower part of the gantry frame and fixedly connected to a pressure plate, a plurality of evenly distributed upper molds fixedly connected to the lower end face of the pressure plate, a mold base rotatably connected to the upper end face of the base, a plurality of evenly distributed through holes opened inside the mold base, a lower mold slidably connected inside each of the plurality of through holes, a limit ring fixedly connected to the outer wall of each of the plurality of lower molds, and a limit groove opened inside each of the plurality of through holes. By sliding the lower mold inside the mold base, when the upper mold moves downward, it can push the lower mold downward, thereby pushing out the material blocked in the through holes. During the alternating operation of the two sides of the mold base, the material that was stuck last time can be pushed out, preventing the material from getting stuck and facilitating material discharge.

[0004] However, the above-mentioned alumina catalyst carrier forming device has the following problems: 1. During the die pressing process, the material is formed and pressed, but there is a distance between the dies, which causes some material to be unable to be formed and pressed. Due to the distance between the dies, some material will be formed and pressed, while others will only be pressed and not formed. Therefore, after the processed material is flipped and falls into the discharge port, there will be successfully processed material and unprocessed material that need to be manually screened again. 2. The hopper is a frame with open top and bottom. During the horizontal movement of the hopper, it cannot be guaranteed that the material can move completely to the top of the die base. Some material will pass under the hopper and remain in the original position during the movement. Summary of the Invention

[0005] This invention overcomes the shortcomings of the prior art and provides an extrusion molding device for alumina catalyst carriers.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an extrusion molding device for alumina catalyst carrier, comprising: a housing, a rotating component disposed within the housing, a bearing component connected to the rotating component, a cabinet disposed at the bottom of the housing, and a power component disposed at the bottom of the cabinet;

[0007] The rotating assembly includes: a first servo motor disposed on the outer surface of the housing, and a coupling connected to the servo motor;

[0008] The bearing assembly includes: a mold base connected to the coupling shaft, and a through hole disposed on the mold base;

[0009] The power assembly includes: a base connected to the inner wall of the bottom of the cabinet, and a second servo motor mounted on the base;

[0010] A bearing is connected to the second servo motor, and a rotating shaft is connected to the second servo motor. A turntable is installed on the rotating shaft.

[0011] In a preferred embodiment of the present invention, a lower mold is provided inside the mold base, and a plurality of limiting blocks are provided on the outer surface of the lower mold, and the plurality of limiting blocks are disposed in the limiting groove.

[0012] In a preferred embodiment of this utility model, the turntable is provided with a plurality of small holes, the diameter of which is 5 mm larger than the diameter of the through hole.

[0013] In a preferred embodiment of this utility model, a support frame is provided on the top of the box, and a push rod and several limiting rods are connected through the top of the support frame.

[0014] In a preferred embodiment of this utility model, a pressure plate is connected to the bottom of the push rod and the limiting rod.

[0015] In a preferred embodiment of this utility model, the bottom of the lower pressure plate is provided with a plurality of upper molds.

[0016] In a preferred embodiment of this utility model, a material bin is provided on the top of the box, and the mold base is located inside the material bin.

[0017] In a preferred embodiment of this utility model, an inclined plate is provided on the top of one side of the material silo, and a support foot is provided at the bottom of the inclined plate.

[0018] In a preferred embodiment of this utility model, the base is fixed to the bottom of the cabinet through several screw holes.

[0019] In a preferred embodiment of this utility model, a handle is provided on one side of the outer surface of the cabinet.

[0020] This utility model solves the defects existing in the background technology, and has the following beneficial effects:

[0021] (1) In this utility model, a material bin is provided on the top of the box body, and the mold base is located inside the material bin. The material bin does not need to be moved, reducing material waste during movement and avoiding the need to move the material bin during production. This reduces waste caused by spillage or leakage of material during movement, improves material utilization, lowers production costs, and makes the entire production process more economical and efficient. Material can directly enter the mold base from the material bin without additional transfer steps, greatly shortening material conveying time and reducing downtime caused by material transfer, thereby significantly improving production efficiency.

[0022] (2) In this utility model, the material enters the through hole, the push rod drives the lower pressure plate to press down, the upper mold squeezes the lower mold, so that the alumina catalyst carrier is extruded and formed, ensuring the dimensional accuracy and shape consistency of the alumina catalyst carrier. The first servo motor drives the coupling shaft and the mold base to rotate, so that the formed material and the unformed material enter the next processing flow.

[0023] (3) In this invention, shaped and unshaped materials are flipped and fall into the turntable. The first servo motor drives the turntable to rotate. The shaped materials fall into the cabinet through the small holes, while the unshaped materials, due to their irregular shape, do not fall into the cabinet through the small holes. This achieves automatic classification of finished and unfinished products, avoiding the tedious process of manual screening and improving the efficiency of material management. Operators can remove the finished and unfinished materials using the handles. Attached Figure Description

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0032] like Figures 1-5 As shown, an extrusion molding apparatus for alumina catalyst carrier includes: a housing 1, a rotating component disposed within the housing 1, a bearing component connected to the rotating component, a cabinet 2 disposed at the bottom of the housing 1, and a power component disposed at the bottom of the cabinet 2.

[0033] In this invention, a support frame 16 is provided on the top of the housing 1, and a push rod 17 and several limiting rods 18 are connected through the top of the support frame 16. A lower pressure plate 19 is connected to the bottom of the push rod 17 and the limiting rods 18. Several upper molds 20 are provided at the bottom of the lower pressure plate 19. The push rod 17 applies downward pressure through an external driving device. The push rod 17 drives the lower pressure plate 19 and the upper molds 20 to move downward. The upper molds 20 cooperate with the lower molds 12 in the mold base 5 to extrude and shape the material. The limiting rods 18 ensure the vertical movement trajectory of the lower pressure plate 19 and prevent deviation or shaking.

[0034] In this invention, the rotating component includes: a first servo motor 3 disposed on the outer surface of the housing 1, and a coupling 4 connected to the servo motor; the bearing component includes: a mold base 5 connected to the coupling 4, and a through hole 6 disposed on the mold base 5; a lower mold 12 is disposed inside the mold base 5, and a plurality of limiting blocks 13 are disposed on the outer surface of the lower mold 12, and the plurality of limiting blocks 13 are disposed in the limiting groove 14. The lower mold 12 cooperates with the upper mold 20 to extrude and form the material, ensuring that the shape and size of the formed material meet the requirements. The first servo motor 3 is started, driving the mold base 5 to rotate through the coupling 4, so that the formed material and the unformed material enter the next processing step. Some formed material may remain in the through hole 6 without falling off. The upper mold 20 extrudes the lower mold 12 again, and the limiting blocks 13 are pushed to the bottom of the limiting groove 14 under pressure, making it easier for the formed material to fall off.

[0035] In this invention, the power assembly includes: a base 7 connected to the inner wall of the bottom of the cabinet 2; a second servo motor 8 mounted on the base 7; a bearing 9 connected to the second servo motor 8; a rotating shaft 10 connected to the second servo motor 8; and a turntable 11 mounted on the rotating shaft 10. The turntable 11 has several small holes 15, the diameter of which is 5 mm larger than the diameter of the through holes 6 to ensure that the formed material can pass through smoothly, while the unformed material, due to its irregular shape, cannot pass through. The formed and unformed materials fall from the through holes 6 of the mold base 5 onto the turntable 11. The second servo motor 8 starts, driving the turntable 11 to rotate via the rotating shaft 10. The design of the small holes 15 on the turntable 11 allows the formed material to pass through smoothly and fall into the cabinet 2. The unformed material, unable to pass through the small holes 15, remains on the turntable 11. This small hole 15 screening mechanism ensures that only formed materials meeting the size requirements enter the cabinet 2, effectively preventing defective products from being mixed into the finished product and improving the stability of product quality.

[0036] In this invention, a material bin 21 is provided on the top of the housing 1, and the mold base 5 is located inside the material bin 21. An inclined plate 22 is provided on the top side of one side of the material bin 21, and a support foot 23 is provided at the bottom of the inclined plate 22. The inclined plate 22 guides the material to roll into the material bin 21 and slide onto the mold base 5, reducing material waste during movement and avoiding the need to move the material bin 21 during production. This reduces waste caused by spillage or leakage of material during movement and improves material utilization.

[0037] In this utility model, the base 7 is fixed to the bottom of the cabinet 2 through several screw holes 24.

[0038] In this utility model, a handle 25 is provided on one side of the outer surface of the cabinet 2, which makes it convenient for operators to take out finished and unfinished materials, simplifies the material collection and sorting process, and reduces the difficulty of operation.

[0039] In use, the raw material of the alumina catalyst carrier is placed in the inclined plate 22 and rolls down onto the mold base 5 in the material bin 21. The push rod 17 applies downward pressure, and the limiting rod 18 ensures the vertical movement trajectory of the lower pressure plate 19, preventing deviation or shaking and ensuring the stability of the molding process. The push rod 17 drives the lower pressure plate 19 and the upper mold 20 to move downward. The upper mold 20 cooperates with the lower mold 12 in the mold base 5 to extrude and mold the material. The first servo motor 3 starts and drives the mold base 5 to rotate through the connecting shaft 4, allowing the molded and unmolded materials to enter the next processing step. Some molded material may remain in the through hole 6 without falling off. The upper mold 20 extrudes the lower mold 12 again, and the limiting block 13 is pushed to the bottom of the limiting groove 14 under pressure, making it easier for the molded material to fall off. The second servo motor 8 starts and drives the turntable 11 to rotate through the rotating shaft 10. The design of the small holes 15 on the turntable 11 allows the shaped material to fall smoothly into the cabinet 2 through the small holes 15, while the unshaped material remains on the turntable 11. The operator can remove the finished material and the unshaped material from the cabinet 2 through the handles 25 on the outer surface of the cabinet 2.
