A catalyst carrier molding device

Abstract

This utility model discloses a catalyst carrier forming device, belonging to the technical field of forming devices. It includes an extrusion forming machine, with a conveyor on one side for conveying the formed catalyst carrier. The conveyor includes a transmission belt and a motor for driving the transmission belt. A cutting assembly driven by the motor is located at the top of the conveyor, and a cleaning assembly driven by the motor is located at the bottom of the conveyor. In this utility model, a linkage transmission mechanism of "drive wheel-driven wheel-rotating rod-swinging rod" is adopted. The drive wheel is driven by the motor, which drives the driven wheel via the anti-slip conveyor belt, causing the rotating rod to perform circular motion. The swinging rod then drives the fixed column and the cutter to swing up and down.

Description

Technical Field

[0001] This utility model belongs to the field of molding device technology, and in particular relates to a catalyst carrier molding device. Background Technology

[0002] Catalyst supports, also known as carriers, are a component of supported catalysts. They form the framework of the catalyst's active components, supporting and dispersing them, while also increasing the catalyst's strength. Most supports are products from the catalyst industry, commonly including alumina supports, silica gel supports, activated carbon supports, and certain natural products such as pumice and diatomaceous earth. Currently, catalyst support forming equipment is typically used to extrude and shape the catalyst supports, followed by conveyor transport, cutting and separation, and final collection. Existing technologies disclose several utility model patents in the field of molding devices, including utility model patent application number CNCN221873319U, which discloses a catalyst carrier molding device. This device includes an extrusion molding machine, a conveyor on one side of the extrusion molding machine, a cutting component on the top side of the conveyor away from the extrusion molding machine, a conveyor belt, a motor, and a cleaning component driven by the motor on the bottom side of the conveyor away from the extrusion molding machine for cleaning the conveyor belt. A sieve hopper is located on the side wall of the conveyor away from the extrusion molding machine, and a collection box is located below the sieve hopper. This utility model uses the cleaning component to clean the conveyor belt, preventing residual catalyst carrier debris from affecting subsequent conveying operations. The motor simultaneously drives the conveyor belt and the cleaning rollers on the cleaning component, effectively reducing overall costs. It also allows for the separate collection of catalyst carriers of different sizes after cutting, preventing them from mixing and facilitating subsequent packaging.

[0003] Disadvantages of existing technology: Insufficient cutting accuracy and stability: The cutting component adopts an electric push rod to drive the cutter. During frequent start-stop operations, the electric push rod is prone to positional deviation. Moreover, it is difficult to accurately constrain the movement trajectory of the cutter by relying solely on the limit rod, resulting in a large error in the length of the catalyst carrier being cut. Poor cleaning effect: The cleaning assembly only uses belt drive to keep the cleaning roller in contact with the bottom of the conveyor belt, lacking a dynamic adjustment mechanism for the pressure of the cleaning roller. When the conveyor belt wears or deforms during operation, gaps will appear between the cleaning roller and the conveyor belt, making it difficult to remove stubborn materials. Residual debris may mix into the product, reducing product quality. At the same time, the accumulated debris will also affect the normal operation of the conveyor belt. Low screening efficiency and inaccurate grading: The screening bucket relies solely on the material's own gravity and the thrust of the conveyor belt for screening, without vibration assistance. Catalyst carriers of different sizes are prone to squeezing and clogging the screen holes, resulting in low screening efficiency.

[0004] Based on this, the present invention designs a catalyst carrier forming device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a catalyst carrier forming device to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A catalyst carrier forming apparatus includes an extrusion forming machine. A conveyor for conveying the formed catalyst carrier is provided on one side of the extrusion forming machine. The conveyor includes a conveyor belt and a motor for driving the conveyor belt. A cutting assembly driven by the motor is provided at the top of the conveyor, and a cleaning assembly driven by the motor is provided at the bottom of the conveyor. A sieve plate is fixedly provided on the right side of the conveyor, and a support plate is fixedly connected to the front side of the sieve plate. A vibrating screening assembly driven by the motor is provided on the left side of the support plate. A storage box is provided at the bottom of the conveyor, and the same support frame is fixedly connected to the front and rear sides of the conveyor.

[0007] As a further description of the above technical solution: the cutting assembly includes a drive wheel fixedly connected to the outside of the motor output end, the drive wheel being driven by a driven wheel via an anti-slip conveyor belt, a rotating shaft being fixedly connected inside the driven wheel, a rotating rod being fixedly connected to the front end of the rotating shaft, a swing rod being hinged to the rotating rod via a pin, a fixed column being rotatably connected to the bottom end of the swing rod, a cutter being fixedly connected to the outside of the fixed column, and a slider being fixedly connected to the front end of the fixed column.

[0008] As a further description of the above technical solution: the cleaning assembly includes a first gear fixedly connected to the output end of the motor, a second gear meshing with the first gear, a fixed shaft fixedly connected inside the second gear, a cleaning roller fixedly connected outside the fixed shaft, and a connecting rod fixedly connected to the left side of the support frame. A first elastic telescopic rod is fixedly connected to the top of the connecting rod, and a scraper is fixedly connected to the top of the first elastic telescopic rod. Both the cleaning roller and the scraper abut against the bottom of the conveyor belt.

[0009] As a further description of the above technical solution: the vibrating screening assembly includes a cam fixedly connected to the output end of the motor, a vibrating block abutting against the outside of the cam, a second elastic telescopic rod fixedly connected to the right side of the vibrating block, the second elastic telescopic rod fixedly connected inside the support plate, and the vibrating block can intermittently contact the support plate after being squeezed by the cam, thereby driving the support plate and the screen plate to vibrate.

[0010] As a further description of the above technical solution: a limiting groove is provided in the support frame, the slider is slidably connected in the limiting groove, and a number of sieve holes are provided in the sieve plate.

[0011] As a further description of the above technical solution: the motor is fixedly connected inside the support frame, and both the fixed shaft and the rotating shaft are rotatably connected inside the support frame. The first gear and the second gear are provided with dustproof covers for dust prevention.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. In this utility model, a linkage transmission mechanism consisting of "drive wheel - driven wheel - rotating rod - swing rod" is adopted. The drive wheel is driven by a motor, which drives the driven wheel through an anti-slip conveyor belt, causing the rotating rod to make a circular motion. Then, the swing rod drives the fixed column and the cutter to swing up and down. The slider at the front end of the fixed column slides in the limiting groove, forming a precise linear reciprocating motion, which effectively avoids the cutter from deviating and can stably cut catalyst carriers of a fixed length, significantly improving the product's precision and quality consistency.

[0013] 2. In this invention, a gear transmission drives the cleaning roller to rotate, while a scraper supported by an elastic telescopic rod is also provided. The first gear meshes with the second gear, driving the cleaning roller to roll and clean. The elastic telescopic rod provides continuous pressure to the scraper, ensuring it fits tightly against the bottom of the conveyor belt. This design adapts to the deformation of the conveyor belt, promptly removing ordinary debris and stubborn residues, achieving thorough cleaning without blind spots, preventing material residue from contaminating the product, and ensuring the cleanliness and stable operation of the conveyor belt.

[0014] 3. In this invention, a cam driven by a motor compresses the second elastic telescopic rod by squeezing the vibrating block. When the cam convexes and rotates away, the vibrating block rebounds and intermittently collides with the support plate, causing the screen plate to vibrate at high frequency. Compared with the static screening technology of the prior art, this vibrating screening method can effectively prevent the catalyst carrier from clogging the screen holes, accelerate the material through the screen holes by using high-frequency vibration, achieve precise particle size classification, efficiently separate qualified particles from waste materials, greatly improve the product qualification rate, and facilitate subsequent packaging and use.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-5 This utility model provides a technical solution: A catalyst carrier forming apparatus includes an extrusion forming machine 1. A conveyor 2 for conveying the formed catalyst carrier is provided on one side of the extrusion forming machine 1. The conveyor 2 includes a conveyor belt and a motor 3 for driving the conveyor belt. A cutting assembly driven by the motor 3 is provided on the top of the conveyor 2. A cleaning assembly driven by the motor 3 is provided on the bottom of the conveyor 2. A sieve plate 4 is fixedly provided on the right side of the conveyor 2. A support plate 5 is fixedly connected to the front side of the sieve plate 4. A vibrating screening assembly driven by the motor 3 is provided on the left side of the support plate 5. A storage box 6 is provided at the bottom of the conveyor 2. The same support frame 7 is fixedly connected to the front and rear sides of the conveyor 2.

[0019] The cutting assembly includes a drive wheel 8 fixedly connected to the output end of motor 3. Drive wheel 8 is connected to driven wheel 9 via a non-slip conveyor belt. A rotating shaft 10 is fixedly connected inside driven wheel 9. A rotating rod 11 is fixedly connected to the front end of rotating shaft 10. A swing rod 12 is hinged to rotating rod 11 via a pin. A fixed column 13 is rotatably connected to the bottom end of swing rod 12. A cutter 14 is fixedly connected to the outside of fixed column 13. A slider 15 is fixedly connected to the front end of fixed column 13. The transmission method using drive wheel 8, non-slip conveyor belt, and driven wheel 9 allows for more flexible adjustment of cutting speed and frequency. Motor 3 drives drive wheel 8, which in turn drives driven wheel 9, causing rotating shaft 10 to rotate, which in turn drives rotating rod 11 and swing rod 12, achieving the swing cutting of cutter 14. This method allows adjustment of motor 3 speed according to different cutting requirements, thereby changing the cutting speed and adapting to the cutting of catalyst carriers of different lengths and hardnesses.

[0020] The cleaning assembly includes a first gear 16 fixedly connected to the output end of the motor 3, a second gear 17 meshing externally with the first gear 16, a fixed shaft 18 fixedly connected internally to the second gear 17, and a cleaning roller 19 fixedly connected externally to the fixed shaft 18. It also includes a connecting rod 20 fixedly connected to the left side of the support frame 7, a first elastic telescopic rod 21 fixedly connected to the top of the connecting rod 20, and a scraper 22 fixedly connected to the top of the first elastic telescopic rod 21. Both the cleaning roller 19 and the scraper 22 abut against the bottom of the conveyor belt. The cleaning roller 19 is responsible for initial cleaning of large areas, while the scraper 22 can perform secondary cleaning of some sticky residues, improving the cleaning effect. Moreover, the cleaning roller 19 is driven by gears, which is more stable than belt drive and avoids slippage.

[0021] The vibrating screening assembly includes a cam 23 fixedly connected to the output end of the motor 3. A vibrating block 24 abuts against the outside of the cam 23. A second elastic telescopic rod 25 is fixedly connected to the right side of the vibrating block 24 and is fixedly connected inside the support plate 5. When the vibrating block 24 is squeezed by the cam 23, it can intermittently contact the support plate 5, thereby driving the support plate 5 and the screen plate 4 to vibrate. The motor 3 drives the cam 23 to make the vibrating block 24 intermittently contact the support plate 5, thereby driving the screen plate 4 to vibrate. This vibration function can effectively separate mutually adhered catalyst carriers, improve screening efficiency, and allow catalyst carriers of different particle sizes to more accurately pass through the screen holes and enter the collection box 6.

[0022] A limiting groove 26 is provided inside the support frame 7, and the slider 15 is slidably connected in the limiting groove 26. Several screen holes are provided inside the screen plate 4. The motor 3 is fixedly connected in the support frame 7. The fixed shaft 18 and the rotating shaft 10 are both rotatably connected in the support frame 7. The first gear 16 and the second gear 17 are provided with dustproof covers for dust prevention. The dustproof covers protect the gear transmission system and extend the service life of the equipment.

[0023] Working principle and usage: The catalyst carrier raw material is extruded into strip or columnar semi-finished products by the extrusion molding machine 1 and directly output to the conveyor belt of the conveyor 2. The motor 3 drives the conveyor belt to move at a constant speed, continuously conveying the formed carrier to the bottom of the cutting component. When the motor 3 drives the drive wheel 8 to rotate, the rotating wheel drives the driven wheel 9 and the rotating shaft 10 to rotate synchronously through the anti-slip conveyor belt, which in turn drives the rotating rod 11 to rotate. Under the action of the pin, the swing rod 12 swings back and forth, and drives the fixed column 13, the cutter 14 and the slider 15 to move up and down and back and forth in the limiting groove 26 for cutting. At the same time, the motor 3 drives the first gear 16 to rotate, and drives the second gear 17, the fixed shaft 18 and the cleaning roller 19 to rotate continuously, thereby removing residual materials at the bottom of the conveyor belt. The first elastic telescopic rod 21 supports the scraper 22 to abut against the bottom of the conveyor belt, and works with the cleaning roller 19 to achieve double cleaning and prevent blockage. The motor 3 drives the cam 23 to rotate, periodically squeezing the vibrating block 24. The vibrating block 24 is connected to the support plate 5 through the second elastic telescopic rod 25. When squeezing, the support plate 5 and the sieve plate 4 vibrate as a whole, accelerating the carrier through the sieve hole. The size of the sieve hole matches the target carrier specification. Qualified products fall into the storage box 6 through the sieve hole, while unqualified products remain on the sieve plate 4 and need to be recut or processed.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
