Description

Technical Field

[0002] Modern industrial production widely uses solid catalysts to enable efficient industrial processes and ensure industrial operation. In experiments, a large amount of catalyst is required. Since catalysts are in powder form, they are often pressed into tablets for easier use. Therefore, a corresponding tableting device is needed to press the catalyst powder into tablets.

[0003] By comparing a catalyst tableting device with patent publication number CN222742229U, in this solution, the hydraulic rod is controlled to contract so that the hydraulic rod drives the pressing plate to descend. The descending pressing plate can press and form the powder inside the forming tank through several pressing blocks at its bottom. However, after the catalyst powder is pressed and formed, a small amount of catalyst powder may remain on the surface of the formed catalyst tablet. If this part of the powder is not recovered, it will cause waste of the catalyst powder. Utility Model Content

A material holding structure for holding catalyst powder is provided on the surface of the rotating disk 201.

[0033] The material holding structure includes multiple material holding slots 212 formed on the surface of the rotating disk 201. The multiple material holding slots 212 are distributed around the center of the rotating disk 201. A top plate 211 is slidably installed inside the material holding slot 212. A top rod 210 is fixed at the bottom end of the top plate 211. A storage spring is connected between the top plate 211 and the material holding slot 212.

[0034] The discharge structure includes a hopper 217 located on the left side of the discharge plate 205. The bottom of the hopper 217 is inclined, and multiple filter holes 218 are provided at the bottom of the hopper 217. A recovery box 219 is provided below the filter holes 218. The recovery box 219 is slidably connected to the hopper 217. A baffle 220 is provided on the lower side of the hopper 217. A cylinder 221 is provided between the top of the baffle 220 and the hopper 217. A holding box 222 is provided below the hopper 217. The holding box 222 is fixedly connected to the base 100. The hopper 217 has a cleaning structure inside for cleaning residual powder on the surface of the catalyst tablets.

[0035] The cleaning structure includes a soft brush roller 224 rotatably mounted on the inner wall of the hopper 217. The soft brush roller 224 is made of silicone. A rotary motor 223 is installed at the rotating end of the soft brush roller 224. The output end of the rotary motor 223 is fixed to the rotating end of the soft brush roller 224 through a coupling. A striking structure for striking the hopper 217 is provided on the rear side of the hopper 217.

[0036] The impact structure includes a fixed sleeve 225 fixedly mounted at the rear end of the soft brush roller 224. Multiple impact blocks 226 are slidably mounted on the surface of the fixed sleeve 225. Impact springs connect the impact blocks 226 to the fixed sleeve 225. A fixed block 227 is fixed on the rear side of the hopper 217 near the top of the fixed sleeve 225. Both the fixed block 227 and the impact blocks 226 have curved surfaces on their closest sides. When the rotary motor 223 is started, it drives the soft brush roller 224 to rotate. The soft brush roller 224 cleans the powder remaining on the surface of the flake catalyst. Simultaneously, the soft brush roller 224... When rotating, the fixed sleeve 225 rotates, which in turn drives multiple striking blocks 226 to rotate. The striking blocks 226 press against the fixed blocks 227, causing the striking blocks 226 to strike the fixed blocks 227 when they come into contact with them. This causes the fixed blocks 227 to vibrate, which in turn causes the hopper 217 to vibrate. This vibration and sweeping action removes the catalyst powder remaining on the surface of the flake catalyst. This powder falls through the filter holes 218 into the recycling bin 219 below for recycling, facilitating its reuse later.

[0037] In this embodiment: the feeding mechanism includes a support plate 301 disposed on the front side of the base 100, a feeding bin 302 is provided at the top of the support plate 301, a feeding pipe 303 is installed at the bottom of the feeding bin 302, a solenoid valve 304 is installed on the feeding pipe 303, and the bottom of the feeding pipe 303 is located between the rotating disk 201 and the scraper 204.

[0038] Working principle: First, a large amount of catalyst powder is poured into the feeding hopper 302. The powder is fed between the rotating disk 201 and the scraper 204 through the feeding pipe 303. The amount of powder fed is controlled by the solenoid valve 304. Then, the drive motor 202 is started to drive the drive shaft 203 to rotate. The drive belt drives the rotating disk 201 to rotate. When the rotating disk 201 rotates, it cooperates with the scraper 204 to scrape the powder on the surface of the rotating disk 201 into the multiple material collection grooves 212 on the surface of the rotating disk 201.

[0039] Then, the rotating disk 201 continues to rotate, driving the fixed disk 206 to rotate, which in turn drives multiple protruding plates 208 to rotate. When the protruding plates 208 and the pressing plate 214 at the bottom of the connecting plate 213 press against each other, the pressing plate 214 will press the protruding plates 208 downward, causing the protruding plates 208 to drive the pressing column 209 to move downward. The pressing column 209 is inserted into the material storage tank 212 below and presses the powder inside the material storage tank 212 into a sheet-like catalyst. Then, the rotating disk 201 continues to rotate, driving multiple... When the top plate 211 rotates, the top rod 210 at the bottom of the top plate 211 encounters the top column 216. The top column 216 will press the top rod 210 upward, pushing the top rod 210 to push the top plate 211 upward, pushing the formed flake catalyst inside the material tank 212 upward. With the centrifugal force generated when the rotating disk 201 rotates, the flake catalyst is thrown along the discharge plate 205 into the hopper 217. The baffle 220 blocks the flake catalyst, causing a large amount of flake catalyst to accumulate here.

[0040] Then, the rotary motor 223 is started to drive the soft brush roller 224 to rotate. The soft brush roller 224 cleans the powder remaining on the surface of the flake catalyst. At the same time, the soft brush roller 224 drives the fixed sleeve 225 to rotate. The fixed sleeve 225 drives multiple striking blocks 226 to rotate. The striking blocks 226 squeeze the fixed blocks 227 against each other, causing the striking blocks 226 to strike the fixed blocks 227 when they touch them. This causes the fixed blocks 227 to vibrate, which in turn causes the feeding hopper 217 to vibrate. Thus, the catalyst powder remaining on the surface of the flake catalyst is cleaned off by vibration and sweeping. This powder falls through the filter holes 218 into the recycling box 219 below for recycling, which is convenient for secondary use later. Then, the cylinder 221 is started to drive the baffle 220 to move upward, removing the obstruction to the flake catalyst. A large amount of flake catalyst rolls down the inclined surface of the feeding hopper 217 into the material collection box 222 below for collection, completing the catalyst tableting operation.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
