Description

Technical Field

[0001] This invention relates to the field of solid catalyst production technology, and in particular to a mold support frame for a porous catalyst. Background Technology

[0002] Solid catalysts, as an important component of modern catalysis technology, are widely used in chemical, petroleum, and environmental protection fields. Currently, solid catalysts are typically formed using rectangular or circular templates with a certain number of forming holes. The material flows into the holes and cools to form the catalyst.

[0003] However, this traditional template has the following problems: the material can only flow in from the edge of the mold hole, resulting in uneven material distribution near the edge and near the center of the mold hole. This leads to inconsistent density of the catalyst after it is formed, which greatly affects the catalytic effect of the catalyst and urgently needs to be improved. Summary of the Invention

[0004] The purpose of this invention is to provide a mold support frame for porous catalysts, which can effectively solve the problem of uneven material distribution during the catalyst forming process, resulting in inconsistent overall density of the catalyst after forming, and greatly improve the overall quality of solid catalyst products.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0006] A mold support frame for a porous catalyst includes a support frame body, which is installed in a circular mold hole on a mold plate. The plane where the upper opening of the mold hole is located is higher than the top surface of the support frame body. A mold ring is provided in the mold hole, and the support frame body is located at the top of the mold ring. The center of the support frame body is provided with a pinhole matching the number of catalyst channels. The pinhole extends into the forming cavity of the mold ring. Multiple inflow holes for material to flow into the forming cavity are evenly distributed outside the pinhole.

[0007] By adopting the above technical solution, the catalyst material is fed directly onto the mold plate from above and flows along its upper surface to the mold hole. When the material reaches the mold hole, it is blocked by the support frame body and flows to the top surface of the support frame body. Then, it flows evenly into the forming cavity of the mold ring through multiple inflow holes on the top of the support frame body. Since the inflow holes are evenly distributed on the outside of the central pin hole of the support frame body, the material flows into the forming cavity from multiple positions and directions. Therefore, after the material enters the forming cavity, it will neither concentrate in the center nor shift to the edge, effectively ensuring the uniformity of material distribution in the forming cavity during the catalyst forming process. This ensures the consistency of the overall density of the formed catalyst, thereby enhancing the performance and service life of the catalyst. The pin hole set in the center of the support frame body is used to achieve precise forming of the catalyst channels, further enhancing the structural strength and catalytic performance of the catalyst.

[0008] A further feature of the present invention is that the main body of the support frame is cylindrical and matches the inner diameter of the mold hole.

[0009] By adopting the above technical solution, the main body of the cylindrical support frame can be directly connected to the mold hole, which is simple in structure, low in manufacturing cost, and easy to install.

[0010] A further feature of the present invention is that the main body of the support frame is a polygonal plate, including but not limited to triangles, quadrilaterals or other polygons.

[0011] By adopting the above technical solution, multiple gaps can be formed between the sides of the polygonal plate-shaped support frame and the inner wall of the mold hole. This not only ensures that some material flows into the molding cavity through the gaps, thereby further improving the uniformity of material distribution after entering the molding cavity, but also allows air to be discharged from the molding cavity during the material entry process, achieving a pressure relief effect. This ensures a smooth molding process and high catalyst quality. In addition, the polygonal design of the support frame reduces the contact area with the inner wall of the mold hole, greatly reducing wear between the mold hole and the support frame, and effectively improving the service life of the mold.

[0012] A further provision of the present invention is that the bottom of the support frame body is detachably connected to the top of the mold ring through multiple support parts. The support part includes a nut sleeve fixed to the top of the mold ring and a screw that is threadedly engaged with the nut sleeve. The lower end of the screw passes through the support frame body and is threadedly connected to the nut sleeve. The support frame body is threadedly connected to the screw.

[0013] By adopting the above technical solution, the main body of the support frame is detachably connected to the top of the mold collar through the support part, which makes it easy to replace and maintain the main body of the support frame, greatly improving the maintenance efficiency of the device and the flexibility of the production process. The design of the support part using screw and nut threaded connection is not only simple in structure and easy to operate, but also ensures that the main body of the support frame is firmly installed, while also allowing for easy adjustment of the installation height of the main body of the support frame, ensuring that the material flow process can achieve the best molding effect, and making the quality of catalyst molding more stable.

[0014] A further feature of the present invention is that the inflow hole is an arc-shaped hole, and the arc-shaped holes are located on the same circumference.

[0015] By adopting the above technical solution, the arc-shaped holes help guide the material to flow into the forming cavity in a more natural way. This not only effectively reduces the accumulation and blockage of material at the inflow holes, but also reduces the unevenness caused by resistance during material flow. This allows the material to be more evenly distributed when entering the forming cavity, thereby further improving the overall quality and consistency of the catalyst. In addition, all the arc-shaped holes are evenly distributed on the same circumference, allowing the material to flow into the forming cavity evenly from multiple directions. This effectively avoids the material from concentrating in a certain area or shifting to the edge, further improving the uniformity of material distribution.

[0016] A further feature of the present invention is that the distance from one end of the arc-shaped hole to the center of the support frame body is greater than or less than the distance from the other end to the center of the support frame body.

[0017] By adopting the above technical solution, the different distances from the two ends of the arc-shaped hole to the center cause the material to form a spiral flow path when it flows in. This not only enhances the fluidity of the material and further reduces the risk of material accumulation and blockage at the inflow hole, but also effectively increases the flow speed of the material, greatly shortens the time for the material to fill the molding cavity, and improves production efficiency.

[0018] A further feature of the present invention is that the top of the support frame body is provided with a downwardly extending arc-shaped concave surface, and the end of the arc-shaped hole away from the center of the support frame body is higher than the end of the arc-shaped hole near the center of the support frame body.

[0019] By adopting the above technical solution, the arc-shaped concave surface can guide the material to flow naturally towards the arc-shaped hole. The end of the arc-shaped hole away from the center is higher, and the end closer to the center is lower, forming an inclined flow path, which further enhances the fluidity of the material and makes the material flow more smoothly. This not only reduces the molding defects caused by the generation of bubbles and voids, but also greatly reduces the accumulation and retention of material on the top of the support frame, further reducing the risk of material accumulation and blockage at the inflow hole.

[0020] A further feature of the present invention is that the support frame body has a pin mounting hole at its center for mounting pins, and the pins are threadedly engaged with the pin mounting hole.

[0021] By adopting the above technical solution, the pin at the center of the support frame body is detachably connected to the mounting hole of the pin through thread engagement. This not only simplifies the structure but also makes disassembly and assembly convenient, and facilitates maintenance and replacement, greatly improving the service life of the device.

[0022] The beneficial effects of this invention are:

[0023] 1. This invention uses a support frame to block the material entering the mold orifice, allowing the material to flow evenly into the forming cavity of the mold ring through multiple inflow holes at the top of the support frame. Since the inflow holes are evenly distributed outside the central pin of the support frame, the material flows into the forming cavity from multiple positions and directions. Therefore, after entering the forming cavity, the material neither concentrates in the center nor shifts to the edge, effectively ensuring the uniformity of material distribution within the forming cavity during catalyst forming. This ensures the consistency of the overall density of the formed catalyst, thereby enhancing its performance and service life. The central pin of the support frame is used to achieve precise forming of the catalyst channels, further enhancing the catalyst's structural strength and catalytic performance.

[0024] 2. In this invention, when the main body of the support frame is a polygonal plate, the sides of the polygonal plate-shaped support frame and the inner wall of the mold hole can form multiple gaps. This not only ensures that some material flows into the molding cavity through the gaps, thereby further improving the uniformity of material distribution after entering the molding cavity, but also allows air to be discharged from the molding cavity during the material's entry into the molding cavity, achieving a pressure relief effect. This ensures a smooth molding process and high catalyst quality. Furthermore, the polygonal design of the support frame reduces the contact area with the inner wall of the mold hole, greatly reducing wear between the mold hole and the support frame, and effectively improving the service life of the mold.

[0025] 3. In this invention, the main body of the support frame is detachably connected to the top of the mold collar via the support part, which makes it easy to replace and maintain the main body of the support frame, greatly improving the maintenance efficiency of the device and the flexibility of the production process. The design of the support part using screw and nut threaded connection is not only simple in structure and easy to operate, but also ensures that the main body of the support frame is firmly installed while also allowing for easy adjustment of the installation height of the main body of the support frame, ensuring that the material flow process can achieve the best molding effect, and making the quality of catalyst molding more stable.

[0026] 4. In this invention, the inflow holes on the support frame body are designed as arc-shaped holes, which helps guide the material to flow into the molding cavity in a more natural way. This not only effectively reduces the accumulation and blockage of material at the inflow holes, but also reduces the unevenness caused by resistance during material flow. This allows the material to be more evenly distributed when entering the molding cavity, thereby further improving the overall quality and consistency of the catalyst. In addition, all the arc-shaped holes are evenly distributed on the same circumference, allowing the material to flow into the molding cavity evenly from multiple directions. This effectively avoids the material from concentrating in a certain area or shifting to the edge, further improving the uniformity of material distribution.

[0027] 5. In this invention, the distances from the two ends of the arc-shaped hole to the center are different, which makes the material form a spiral flow path when it flows in. This not only enhances the fluidity of the material and further reduces the risk of material accumulation and blockage at the inflow hole, but also effectively increases the flow speed of the material, greatly shortens the time for the material to fill the molding cavity, and improves production efficiency.

[0028] 6. In this invention, the top of the support frame body is provided with a downward-extending arc-shaped concave surface. The arc-shaped concave surface can guide the material to flow naturally towards the arc-shaped hole. The end of the arc-shaped hole away from the center is higher, and the end closer to the center is lower, forming an inclined flow path, which further enhances the fluidity of the material and makes the material flow more smoothly. This not only reduces the molding defects caused by the generation of bubbles and voids, but also greatly reduces the accumulation and retention of material on the top of the support frame, further reducing the risk of material accumulation and blockage at the inflow hole.

Detailed Implementation

[0035] The technical solution of the present invention will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0036] like Figure 1 As shown, a mold support frame for a porous catalyst includes a support frame body 1, which is installed in a circular mold hole 3 on a mold plate 2. The plane where the upper opening of the mold hole 3 is located is higher than the top surface of the support frame body 1. A mold ring 4 is provided in the mold hole 3, and the support frame body 1 is located at the top of the mold ring 4. A pinhole 5 matching the number of catalyst channels is provided at the center of the support frame body 1. The pinhole 5 extends into the forming cavity of the mold ring 4. A plurality of inflow holes 6 for material to flow into the forming cavity are evenly distributed outside the pinhole 5.

[0037] Furthermore, such as Figure 2 As shown, the main body 1 of the support frame is cylindrical and matches the inner diameter of the mold hole 3.

[0038] Furthermore, such as Figure 3 and Figure 4 As shown, the main body 1 of the support frame is a polygonal plate, including but not limited to triangles, quadrilaterals or other polygons.

[0039] Furthermore, the bottom of the support frame body 1 is detachably connected to the top of the mold ring 4 through multiple support parts 7. The support part 7 includes a nut sleeve 71 fixed to the top of the mold ring 4 and a screw 72 threadedly engaged with the nut sleeve 71. The lower end of the screw 72 passes through the support frame body 1 and is threadedly connected to the nut sleeve 71. The support frame body 1 is threadedly connected to the screw 72.

[0040] Furthermore, the inflow hole 6 is an arc-shaped hole, and the arc-shaped holes are located on the same circumference.

[0041] Furthermore, the distance from one end of the arc-shaped hole to the center of the support frame body 1 is greater than or less than the distance from the other end to the center of the support frame body 1.

[0042] Furthermore, the top of the support frame body 1 is provided with a downwardly extending arc-shaped concave surface 9, and the end of the arc-shaped hole away from the center of the support frame body 1 is higher than the end of the arc-shaped hole near the center of the support frame body 1.

[0043] Furthermore, the support frame body 1 has a pin mounting hole 8 at its center for mounting pin 5, and the pin 5 is threadedly engaged with the pin mounting hole 8.

[0044] The working principle of this invention is as follows: After the catalyst material is fed from above the mold plate 2, it falls directly onto the mold plate 2 and flows along its upper surface to the mold hole 3. When the material reaches the mold hole 3, it is blocked by the support frame body 1 and flows to the top surface of the support frame body 1. Then, it flows evenly into the forming cavity of the mold ring 4 through multiple inflow holes 6 on the top of the support frame body 1. Since the inflow holes 6 are evenly distributed on the outside of the central pin hole 5 of the support frame body 1, the material flows into the forming cavity from multiple positions and directions. Therefore, after the material enters the forming cavity, it will not concentrate in the center or shift to the edge, effectively ensuring the uniformity of the material distribution in the forming cavity during the catalyst forming process. This ensures the consistency of the overall density of the formed catalyst, thereby enhancing the performance and service life of the catalyst. The pin hole 5 set in the center of the support frame body 1 is used to achieve precise forming of the catalyst channels, further enhancing the structural strength and catalytic performance of the catalyst. When the support frame body 1 is polygonal plate-shaped, multiple gaps can be formed between each side of the support frame body 1 and the inner wall of the mold hole 3. This not only ensures that some material flows into the molding cavity of the mold hole 3 through the gaps, thereby further improving the uniformity of material distribution after entering the molding cavity, but also allows air to be discharged from the molding cavity during the material entry process, achieving a pressure relief effect. This ensures a smooth molding process and high catalyst quality. In addition, the polygonal design of the support frame body 1 reduces the contact area with the inner wall of the mold hole 3, greatly reducing wear between the mold hole 3 and the support frame body 1, and effectively improving the service life of the mold.
