Description

Technical Field

[0001] This utility model relates to the field of catalyst particle forming technology, specifically to an electromagnetically controlled catalyst particle forming device. Background Technology

[0002] In the catalyst production process, the quality of particle forming has a crucial impact on catalyst performance. Traditional catalyst particle forming methods often suffer from problems such as low forming precision and poor particle uniformity, making it difficult to meet the demands of modern industry for high-quality catalysts. Therefore, catalyst forming equipment is needed to improve production efficiency.

[0003] In the prior art, utility model patent CN202021585338.5 discloses a precious metal VOCs catalyst particle forming device, including a fixed base plate. A motor is mounted on the top of the fixed base plate via a support frame. A transmission gear is provided at the output end of the motor. A driven gear meshes with the edge of the transmission gear. A connecting shaft is installed through the inside of the driven gear. One end of the connecting shaft is connected to a crossbeam. A support plate is fixedly connected to the surface of the crossbeam. A cooling platform is fixedly installed on the top of the support plate. The precious metal VOCs catalyst particle forming device, by setting the bottom surface area of ​​the cover plate and the top surface area of ​​the forming seat to be equal, ensures that when the cover plate is in contact with the top of the forming seat, it completely covers the surface of the forming hole, thereby improving the cooling and forming effect. By setting multiple forming holes, catalyst particles can be formed in batches, which is beneficial to increasing catalyst production. At the same time, the forming holes facilitate the pouring and unloading of catalyst particles after forming.

[0004] The aforementioned patent provides a device for catalyst particle forming. This device uses a motor to drive a cover plate to compress the catalyst, enabling batch forming of catalyst particles. Although this equipment effectively improves the production efficiency of catalysts, the catalyst particles require high strength during production, which necessitates applying greater pressure to the equipment. This results in high stress on the meshing points of the motor and gears, making them prone to wear. The wear debris can easily cause metal powder and oil contamination in the catalyst, requiring further improvement. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details:

[0020] Example 1

[0021] like Figure 1 and Figure 2As shown, an electromagnetically controlled molding device for catalyst particles includes a molding die 8 and a stamping device. Stamping devices are symmetrically arranged above and below the molding die 8. The catalyst can be compressed into blocks by the mutual pressing of the upper and lower stamping devices within the molding die 8. Each stamping device includes a guide rail 2, a punch plate 4, and punch rods 7. The guide rail 2 and punch plate 4 are sequentially arranged on an outer frame in a direction pointing towards the molding die 8. The punch plate 4 is rotatably mounted. Both the molding die 8 and the punch plate 4 are rotatably mounted on the outer frame, and they rotate synchronously. Multiple punch rods 7 are elastically slidably arranged along the circumference of the punch plate 4. A spring 3 is also included. A spring 3 is fitted onto the part of the punch rod 7 located between the punch plate 4 and the guide rail 2. One end of the spring 3 abuts against the punch plate 4, and the other end is fixedly mounted on the punch rod 7. The punch 7 is located between the guide rail 2 and the forming mold 8, and is elastically positioned towards the guide rail 2. Electromagnetic devices 1 are installed on the end face of the guide rail 2 away from the punch 7, corresponding to the positions of the punch 7. The current connected to each of the multiple electromagnetic devices 1 is different. The forming mold 8 has forming cavities corresponding to the positions of the punch 7. The punches 7 on both sides of the forming mold 8 are magnetically pushed into the forming cavities by the corresponding electromagnetic devices 1. The guide rail 2 is a C-shaped guide rail, with its C-shaped groove facing the punch 7 on the same side. A punch cap 6 is installed on the end of the punch 7 closest to the guide rail 2. The electromagnetic devices 1 and the punch cap 6 repel each other magnetically. The punch cap 6 is located in the C-shaped groove of the guide rail 2 and does not contact the guide rail 2 through the electromagnetic devices 1. This ensures that the punch plate 4 and the punch 7 can perform normal circular motion without contacting the guide rail 2. The punch rod 7 also includes a punch 5. One end of the punch rod 7 is fitted with a punch 5, and the punches 5 on the opposing punch rods 7 on both sides are simultaneously pushed into the forming cavity by magnetic force and abut against each other. The punch 5 is made of stainless steel. During operation, as the punch plate 4 rotates, each punch rod 7 passes through an electromagnetic device 1 with different magnetic forces. As the magnetic force gradually increases or decreases, the punch rods 7 on the upper and lower sides of the forming mold 8 will gradually be pushed together by the magnetic force or gradually opened by the elastic force of the spring 3. When they are closed, the catalyst powder in the forming mold can be processed; when they are opened, catalyst powder can be added to the forming mold 8.

[0022] Example 2

[0023] like Figure 1 and Figure 2As shown, an electromagnetically controlled molding device for catalyst particles includes a molding die 8 and a stamping device. The molding die 8 is symmetrically positioned above and below it. Each stamping device includes a guide rail 2, a punch plate 4, and punch rods 7. The guide rail 2 and punch plate 4 are sequentially mounted on an outer frame in a direction pointing towards the molding die 8. The punch plate 4 is rotatably mounted. Multiple punch rods 7 are elastically slidably mounted on the punch plate 4 along its circumference. A spring 3 is also included; a spring 3 is fitted onto the part of the punch rod 7 located between the punch plate 4 and the guide rail 2. One end of the spring 3 abuts against the punch plate 4, and the other end is fixedly mounted on the punch rod 7. The punch rods 7 are located between the guide rail 2 and the molding die 8, and are elastically positioned towards the guide rail 2. Electromagnetic devices 1 are mounted on the end face of the guide rail 2 away from the punch rods 7, corresponding to the positions of the punch rods 7. The currents connected to the multiple electromagnetic devices 1 are all different. The forming mold 8 has forming cavities corresponding to the positions of the punches 7. The punches 7 on both sides of the forming mold 8 are magnetically pushed into the forming cavities by corresponding electromagnetic devices 1. The guide rail 2 is a C-shaped guide rail, with its C-shaped groove facing the punches 7 on the same side. A punch cap 6 is provided at the end of the punch 7 closest to the guide rail 2. The electromagnetic devices 1 and the punch cap 6 are magnetically repelled. The punch cap 6 is located in the C-shaped groove of the guide rail 2 and does not contact the guide rail 2 through the electromagnetic devices 1. The punches 7 also include punches 5. A punch 5 is provided at one end of the punch 7 inserted into the forming mold 8. The punches 5 on the two opposite punches 7 are simultaneously pushed into the forming cavities by magnetic force and abut against each other. The punches 5 are made of stainless steel.

[0024] The working principle of this utility model is as follows: During operation, as the punch plate 4 rotates, each punch rod 7 passes through an electromagnetic device 1 with different magnetic forces. As the magnetic force gradually increases or decreases, the punch rods 7 on the upper and lower sides of the forming mold 8 will gradually be pushed together by the magnetic force or gradually opened by the elasticity of the spring 3. When they are closed, the catalyst powder in the forming mold can be processed. When they are opened, the catalyst powder can be added to the forming mold 8.

[0025] In summary, this invention effectively reduces wear between devices by symmetrically arranging stamping tools above and below the forming mold 8, with the stamping rods 7 in the stamping tools being pushed vertically by magnetic force, eliminating rotating contact points and thus preventing metal powder and oil contamination in the catalyst. By setting electromagnetic devices 1 with different magnetic forces, the stamping rods 7 on the stamping plate 4 can be made to open and close sequentially during rotation, allowing the forming mold 8 to add catalyst powder while simultaneously extruding and forming the catalyst, effectively improving the production efficiency of catalyst particles.

[0026] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
