Description

Technical Field

[0001] The present invention relates to the technical field of catalyst carrier forming devices, in particular to a new material carrier forming device for an aluminum oxide catalyst. Background Art

[0002] Alumina new material catalyst carrier is a functional material with alumina as the main component. Due to its large specific surface area, good mechanical strength and chemical stability, it can provide an attachment surface for the active components of the catalyst and enhance the efficiency of the catalytic reaction. Its pressing and molding process usually involves evenly mixing alumina powder with an appropriate amount of adhesives, lubricants and other additives, and compressing it through a mold under a certain pressure (usually several to tens of MPa) to make the powder particles tightly combined to form a green body with a specific shape (such as spherical, cylindrical, lamellar, etc.) and size. Subsequent treatments such as drying and calcination further improve its strength and structural stability, and finally obtain a carrier that can be used to load the active components of the catalyst.

[0003] However, after the alumina raw materials and additives enter the discharge frame, when the materials accumulate in the drop frame, the upper material will exert pressure on the lower material, resulting in close contact between the particles and enhanced intermolecular forces, which will easily lead to compaction and agglomeration, affecting the smoothness of subsequent discharge; there is a large friction between the formed catalyst carrier and the inner wall of the bottom mold. During the ejection process, not only is the carrier easily damaged due to uneven force, but the ejection resistance will also increase, reducing the demoulding efficiency; when the spherical carrier rolls from the forming area to the collecting container through the inclined discharge plate, due to the large drop, the carrier will collide with the discharge plate, the container wall and other carriers, and surface damage is likely to occur, thereby reducing product quality.

[0039] Specifically, such as Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 13As shown, the molding machine body 1 is provided with a collecting structure 2, and the collecting structure 2 includes a slide frame 201 slidably connected to the molding machine body 1 and a plurality of movable grooves 202 provided on the slide frame 201. The molding machine body 1 is detachably connected with a collecting vehicle 203, and the molding machine body 1 is slidably connected with a lifting plate 204, and the lifting plate 204 is slidably connected to the collecting vehicle 203. The molding machine body 1 is rotatably connected with a first screw rod 205, and the lifting plate 204 is threadedly connected to the first screw rod 205. The first screw rod 205 rotates, and the thread drives the lifting plate 204 to slide along the molding machine body 1, so as to adjust the height of the lifting plate 204 to adapt to the falling height of the spherical carrier to prevent the spherical carrier from falling after molding.

A through groove 211 is provided at the bottom of the collection vehicle 203.

[0040] When the present invention is in use, first, the material is connected to the feed hole 302 through the external conveying pipe, and the alumina raw material and additives are fed into the discharge frame 301 through the feed hole 302. At the same time, the third driving member 305 (preferably a motor) is started, and the third driving member 305 drives the third screw rod 304 to rotate. Since one of the connecting blocks 303 is threadedly connected to the third screw rod 304, and the connecting block 303 is slidably connected to the molding machine body 1, the discharge frame 301 can be driven to slide on the molding machine body 1 to adjust its position, ensuring that the material can be transported to the subsequent molding area. When the unloading frame 301 moves, the driving shaft 406 on the rack 405 rolls in the driving groove 409 of the driving rod 408 on the fixed plate 407. Since the driving groove 409 is a multi-stage inclined design, it will drive the rack 405 to slide back and forth on the guide frame 404, and the rack 405 is engaged with the gear 402, thereby driving the stirring shaft 401 to rotate, and the stirring rod 403 fixed on the stirring shaft 401 rotates accordingly, stirring the material in the unloading frame 301, effectively preventing the material from agglomerating and piling up, ensuring that it is always evenly dispersed, and ensuring smooth discharge;

[0041] When the material discharge frame 301 moves to above the bottom die 509, the powdered material falls onto the bottom die 509, and then the discharge frame 301 is moved until it is no longer above the bottom die 509. At this time, the sixth driving member 701 (preferably a hydraulic rod) is started, and the sixth driving member 701 drives the pressure plate 702 to move downward, and the multiple pressure molds 703 on the pressure plate 702 drop accordingly, applying pressure to the material in the bottom die 509, so that the material is formed into an alumina catalyst carrier according to the shape of the mold. After the molding is completed, the fourth driving member 508 (preferably a hydraulic rod) is started, and the fourth driving member 508 drives the adjustment frame 507 to slide on the molding machine body 1, and the adjustment frame 507 drives the slip ring 503 to slide synchronously, and the slide groove 504 on the slip ring 503 cooperates with the slide rod 501, and at the same time, the guide ring 510 guides the adjustment ring 502. , when the top of the guide ring 510 is lower than the bottom of the adjusting ring 502, the sliding rod 501 drives the adjusting ring 502 to slide under the action of the tension spring 506, and the inclined surface of the driving ring 505 slides with the inclined surface of the adjusting ring 502, and the adjusting ring 502 drives the bottom mold 509 to move, thereby expanding the bottom mold 509. The expandability of the bottom mold 509 and the adjusting ring 502 can reduce the demoulding resistance, improve the product qualification rate and demoulding efficiency, and at the same time start the fifth driving member 603 (preferably a hydraulic rod). The fifth driving member 603 drives the slide plate 601 to slide along the molding machine body 1, and the guide column 604 is slidably connected to the molding machine body 1 to ensure the smooth movement of the slide plate 601. The multiple lifting columns 602 on the slide plate 601 move accordingly, and the formed spherical carrier is ejected from the bottom mold 509, completing the demoulding operation;

[0042] During collection, after the collection vehicle 203 is plugged into the lifting plate 204 on the molding machine body 1 through the through slot 211, the first driving member 206 (preferably a motor) is started, and the first driving member 206 drives the first screw rod 205 to rotate, and the thread drives the lifting plate 204 to slide along the molding machine body 1, so as to adjust the height of the lifting plate 204 to adapt to the falling height of the spherical carrier. At this time, since the movable groove 202 on the slide frame 201 corresponds to each molding material, the material will be located in the movable groove 202 after being ejected. Subsequently, the second driving member 210 (preferably a motor) is started, and the second driving member 210 drives the second screw rod 208 to rotate, and the thread drives the adjustment plate 207 to slide with the guide rail 209, driving the slide frame 201 to slide, and the movable groove 202 is used to guide the spherical carrier to fall into the collection vehicle 203. At the same time, by continuously adjusting the height of the lifting plate 204 during the collection process, the molded carrier is prevented from colliding and loosening due to excessive drop, thereby improving the collection efficiency and the production quality of the carrier.
