Description

Technical Field

[0001] This utility model belongs to the field of catalyst forming technology, specifically a particle catalyst forming device. Background Technology

[0002] Chinese Patent Publication No. CN213160685U 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 installed at the output end of the motor, and a driven gear meshes with the edge of the transmission gear. A connecting shaft is installed through the driven gear, and one end of the connecting shaft is connected to a crossbeam. A support plate is fixedly connected to the surface of the crossbeam, and a cooling platform is fixedly installed on the top of the support plate. This precious metal VOCs catalyst particle forming device, by setting the bottom area of ​​the cover plate and the top 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 the formed catalyst particles.

[0003] In actual use, the granulated catalyst particles were not screened when they fell into the separator plate after forming. This resulted in larger particles being mixed in, increasing the number of defective granulated catalyst particles and reducing the yield of good granulated catalyst particles. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a granular catalyst forming device, comprising a support, a collection box, and a cooling box. The collection box is movably connected to the top of the support, and the cooling box is supported on the top of the collection box. A servo motor is fixedly connected to the top of the support on the side of the collection box. A drive assembly is provided at the output end of the servo motor. A fan is fixedly connected to the output end of the servo motor on the inner side of the cooling box. A ventilation opening is provided on the inner wall of the cooling box away from the fan. A filter assembly is provided on the inner side of the collection box.

[0005] The inner wall of the cooling box is fitted with a rod, and the inner wall of the collection box is provided with a slot that matches the size of the rod, and the rod is inserted into the slot.

[0006] The output end of the servo motor is connected to the cooling box via a bearing. The output end of the servo motor is fixedly connected to the inner shaft of the bearing, and the inner wall of the cooling box is fixedly connected to the outer shaft of the bearing.

[0007] The drive assembly includes a connecting rod, a cam, a first gear, and a second gear.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. During operation, the granular catalyst is screened by the vibration of the filter screen, so that the granular catalyst particles that meet the specified size pass through the filter screen and fall into the inner side of the collection box for collection, while the larger granular catalyst particles remain on the top of the filter screen and wait for cleaning. This process separates the larger catalyst particles after molding, reduces the number of defective granular catalyst particles, and improves the yield of granular catalyst particles.

[0013] 2. During operation, the cooling box and the collection box are separated by removing the insertion rod from the cooling box.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Example 1, by Figure 1-4 The present invention discloses a particulate catalyst forming device, including a support 1, a collection box 2 and a cooling box 3. The top of the support 1 is movably connected to the collection box 2, and the top of the collection box 2 supports the cooling box 3. The top of the support 1 is fixedly connected to the side of the collection box 2. The output end of the servo motor 5 is provided with a drive assembly 6, which includes a connecting rod 61, a cam 62, a first gear 63 and a second gear 64. The outside of the cooling box 3 is rotatably connected to the connecting rod 61, and the outside of the connecting rod 61 is fixedly connected to the cam 62. The end of the connecting rod 61 is fixedly connected to the first gear 63, and the output end of the servo motor 5 is fixedly connected to the second gear 64.

[0022] Specifically, the size of gear 1 63 is larger than the size of gear 2 64, and gear 1 63 meshes with gear 2 64;

[0023] Specifically, the inner wall of the cooling box 3 is fitted with a rod 4, and the inner wall of the collection box 2 is provided with a slot that matches the size of the rod 4, and the rod 4 is inserted into the slot.

[0024] Example 2, by Figure 1-4 As shown, the output end of the servo motor 5 is fixedly connected to the fan 7 inside the cooling box 3. The inner wall of the cooling box 3 is provided with a vent 8 at the end away from the fan 7. The inner side of the collection box 2 is provided with a filter assembly, which includes a filter screen 9, a fixed frame 10 and a connecting rod 11. The inner wall of the collection box 2 is provided with a sliding groove. The fixed frame 10 is slidably connected to the inner side of the sliding groove. The filter screen 9 is fixedly connected to the inner side of the fixed frame 10. The connecting rod 11 is fixedly connected to the outer side of the fixed frame 10 below the drive assembly 6.

[0025] Specifically, a spring is fixedly connected to the inner side of the slide, and the fixed frame 10 is supported on the spring;

[0026] Specifically, the output end of the servo motor 5 is connected to the cooling box 3 via a bearing. The output end of the servo motor 5 is fixedly connected to the inner shaft of the bearing, and the inner wall of the cooling box 3 is fixedly connected to the outer shaft of the bearing.

[0027] Working principle: When working, the servo motor 5 is started. At this time, the output end of the servo motor 5 rotates, which will drive the gear 64 and the fan 7 to rotate. The rotation of the fan 7 increases the air flow rate in the cooling box 3. When the formed granular catalyst falls into the cooling box 3, it will receive the air force blown by the fan 7, thereby cooling the formed granular catalyst and ensuring that the temperature of the granular catalyst is reduced when it falls into the collection box 2.

[0028] Meanwhile, the rotation of gear 2 64 drives gear 1 63 to rotate, which in turn drives connecting rod 61 to rotate. At this moment, cam 62 on the outside of connecting rod 61 also rotates, thus creating a squeezing force on connecting rod 11. This causes connecting rod 11 to move fixed frame 10 down along the inner wall of collection box 2. Since fixed frame 10 is elastically supported on collection box 2, filter screen 9 will vibrate under the rotation of cam 62, thereby sieving the catalyst particles on filter screen 9. Catalyst particles that meet the specified size pass through filter screen 9 and fall into the inner side of collection box 2 for collection, while larger catalyst particles remain on top of filter screen 9 for cleaning. This process separates larger catalyst particles after molding, reduces defective products in catalyst molding, and improves the yield of good catalyst particles.

[0029] After screening, the cooling box 3 and the collection box 2 are separated by removing the insertion rod 4 from the cooling box 3. Then, the collection box 2 is pulled out from the bottom of the cooling box 3. At the same time, the filter screen 9 on the collection box 2 can be removed to obtain the granular catalyst that meets the requirements.

[0030] Larger catalyst particles are scraped off by the cooling box 3 or remain on top of the filter screen 9 during the movement of the collection box 2.

[0031] The disassembly and installation of the collection box 2 and the cooling box 3 facilitate the collection of particulate catalysts and help with the screening of particulate catalyst formation, which is convenient and quick.
