Description

Technical Field

[0001] This utility model relates to the field of feeding equipment technology, specifically a powdered catalyst feeding device. Background Technology

[0002] In many industrial fields such as chemical engineering, energy, and materials, powdered catalysts are widely used due to their excellent catalytic activity. Their stable delivery directly affects the efficiency of the reaction process, product quality, and production safety. As a key piece of equipment connecting the catalyst storage and reaction systems, the catalyst feeding device undertakes the core task of quantitatively and continuously supplying powdered catalysts according to process requirements.

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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-2 In this embodiment of the present invention, a powdered catalyst feeding device includes a mounting housing 1. A sealing disc 2 is fixedly connected to the upper end of the mounting housing 1. A circular sealing plate 18 is fixedly connected to the upper end of the sealing disc 2. A storage hopper 4 is provided above the circular sealing plate 18. Support frames fixedly connected to the mounting housing 1 are provided on both sides of the storage hopper 4. A transparent cylinder 11 is fixedly connected to the lower end of the storage hopper 4. A conical discharge hood 12 is fixedly connected to the lower end of the transparent cylinder 11. A powder feeding component that cooperates with the conical discharge hood 12 is provided inside the sealing disc 2. The sealing disc 2 and the circular sealing plate 18 above form a sealed space. Catalyst powder enters the sealed space from the storage hopper 4 and is then conveyed by the powder feeding component. The transparent cylinder 11 allows the operator to intuitively observe the conveying status and material level of the powder.

[0028] Please see Figures 3-6The powder feeding assembly includes a feeding turntable 21, which is located inside a sealing disc 2. A drive motor is installed on the upper surface of the mounting housing 1. The output shaft of the drive motor passes through the interior of the sealing disc 2 and is fixedly connected to the middle of the feeding turntable 21. A feeding ring groove 15 is formed on the upper surface of the feeding turntable 21. A powder discharge head 23 is fixedly connected to the circular sealing plate 18 below the conical discharge cover 12. The upper end of the powder discharge head 23 communicates with the lower port of the conical discharge cover 12. A feeding module 16 is slidably connected to the feeding turntable 21. A first arc-shaped protrusion 14 is fixedly connected to the lower end of the feeding module 16. One end of the first arc-shaped protrusion 14 is open... A powder discharge slot 3 is provided. The first arc-shaped protrusion 14 is slidably connected to the feeding ring groove 15. The upper end of the feeding module 16 is provided with a powder discharge step hole 26 communicating with the powder discharge slot 3. The powder discharge head 23 is inserted into the powder discharge step hole 26. The circular sealing plate 18 is provided with a powder discharge mechanism for discharging the catalyst conveyed in the feeding ring groove 15. The drive motor drives the feeding turntable 21 to rotate in the sealing plate 2. The powder falls from the conical discharge cover 12 through the powder discharge head 23 into the powder discharge slot 3 of the feeding module 16, and then enters the feeding ring groove 15. The rotating feeding turntable 21 drives the powder in the feeding ring groove 15 to transfer to the powder discharge mechanism, and then discharges it through the powder discharge mechanism.

[0029] Please see Figures 3-6 The powder dispensing mechanism includes a powder outlet 19, which is fixedly connected to the upper surface of the circular sealing plate 18 on the side away from the powder discharge head 23. A conical powder dispensing head 24 is fixedly connected to the lower end of the powder outlet 19. A powder dispensing module 22 is slidably connected to the feeding turntable 21 below the conical powder dispensing head 24. A second arc-shaped protrusion 28 is fixedly connected to the lower end of the powder dispensing module 22. The second arc-shaped protrusion 28 is slidably connected to the feeding ring groove 15. A powder dispensing slot 27 is opened at one end of the second arc-shaped protrusion 28. A conical powder dispensing hole 25 matching the conical powder dispensing head 24 is opened at the upper end of the powder dispensing module 22. The conical powder outlet head 24 is inserted into the conical powder outlet hole 25, which is connected to the powder outlet trough 27. The circular sealing plate 18 is also provided with an air injection head 20 that penetrates the circular sealing plate 18. During powder discharge, the feeding turntable 21 rotates continuously, conveying the powder carried in its feeding ring groove 15 to the powder discharge module 22. When the conical powder outlet hole 25 on the powder discharge module 22 is connected with the fixed conical powder outlet head 24 to form a channel, the air injection head 20 introduces gas into the sealing plate 2. Using the positive pressure generated, the powder is blown from the powder outlet trough 27 into the conical powder outlet hole 25 and blown out from the powder outlet 19, thus completing the active discharge.

[0030] Please see Figure 2The storage silo 4 is equipped with a powder discharge assembly for discharging the catalyst from the storage silo 4. The powder discharge assembly includes a discharge motor 5, which is installed at the middle of the upper end face of the storage silo 4. A rotating shaft 9 is fixedly connected to the output end of the discharge motor 5. A discharge spiral blade 13 is fixedly connected to the lower end of the rotating shaft 9 inside the conical discharge hood 12. The storage silo 4 is equipped with an auxiliary assembly for assisting the discharge spiral blade 13 in discharging the catalyst. The auxiliary assembly includes a hollow metal rod 10. The hollow metal rod 10 is located inside the storage silo 4. The lower end of the hollow metal rod 10 is located on one side of the conical discharge hood 12, and the upper end of the hollow metal rod 10 is located on one side of the storage silo 4. During powder discharge, the discharge motor 5 drives the rotating shaft 9 to rotate, which in turn drives the discharge spiral blade 13 at the bottom to rotate, pushing the catalyst downward from the conical discharge hood 12. At the same time, gas can be introduced into the hollow metal rod 10. The airflow disturbance prevents the powder from bridging or blocking in the storage silo 4 and the conical discharge hood 12, ensuring smooth material discharge.

[0031] Please see Figure 1 The storage silo 4 is equipped with a material preparation assembly for replenishing the catalyst into the storage silo 4; the material preparation assembly includes a material preparation silo 6, which is located on one side above the storage silo 4. The lower end of the material preparation silo 6 is provided with a connecting pipe that communicates with the storage silo 4, and an electric discharge valve 8 is provided on the connecting pipe; the material preparation silo 6 is used to store spare catalyst. When the material level in the storage silo 4 is insufficient, the electric discharge valve 8 is opened, and the electric discharge valve 8 discharges the catalyst in the material preparation silo 6 into the storage silo 4 to achieve material supply.

[0032] The mounting housing 1 is equipped with an internal gas supply system. The upper end of the mounting housing 1 is equipped with a gas outlet tee connector 7, which is connected to the output end of the gas supply system. The other two ports of the gas outlet tee connector 7 are each connected to a flexible hose. The end of the flexible hose away from the gas outlet tee connector 7 is connected to the hollow metal rod 10 and the gas injection head 20, respectively. The gas supply system inside the mounting housing 1 delivers gas to the gas outlet tee connector 7, and the gas path is divided into two by two flexible hoses, which lead to the hollow metal rod 10 and the gas injection head 20, respectively, for gas supply.

[0033] The circular sealing plate 18 is provided with a transparent plate 17 for observing the catalyst inside the sealing disk 2; the storage bin 4 and the preparation bin 6 are both provided with a feeding port on one side of the upper end, and the feeding port is provided with a cover; the transparent plate 17 is used to directly observe the powder feeding operation inside the sealing disk 2, and the feeding port and the cover are used to initially add or replenish the catalyst into the storage bin 4 and the preparation bin 6. The cover can ensure the sealing of the device during operation and prevent dust from escaping.

[0034] The working principle of this utility model is as follows: the initial catalyst is added to the two silos through the feeding port at the top of the storage silo 4 and the preparation silo 6. After the initial catalyst is added, the cap on the feeding port is closed to ensure the airtightness of the device during operation and prevent dust from escaping. The preparation silo 6 stores spare catalyst in advance to prepare for continuous supply.

[0035] When feeding the powder, the discharge motor 5 at the top of the storage silo 4 is started, and its output end drives the rotating shaft 9 to rotate, which in turn drives the discharge spiral blade 13 located inside the conical discharge hood 12 to rotate, pushing the catalyst in the storage silo 4 downwards towards the conical discharge hood 12; at the same time, the air supply system inside the mounting box 1 is started, and the gas is diverted to the hose through the gas outlet three-way connector 7, and then introduced into the hollow metal rod 10 inside the storage silo 4. The airflow disturbs the catalyst powder in the storage silo 4 and the conical discharge hood 12, preventing powder bridging or blockage and ensuring smooth feeding.

[0036] The catalyst pushed by the discharge spiral blade 13 connects with the powder discharge head 23 on the circular sealing plate 18 through the lower port of the conical discharge cover 12, falls into the powder discharge step hole 26 of the feeding module 16, and then enters the sealed space formed by the sealing plate 2 and the circular sealing plate 18 through the powder discharge slot 3. Finally, it enters the feeding ring groove 15 at the upper end of the feeding turntable 21. The drive motor inside the mounting box 1 starts, and its output shaft drives the feeding turntable 21 to rotate at a constant speed. The catalyst carried in the feeding ring groove 15 rotates synchronously with the turntable and is transferred towards the powder discharge mechanism.

[0037] When the feeding turntable 21 delivers the catalyst to the powder discharge module 22, the gas supply system is diverted to another hose through the gas outlet tee connector 7. Gas is introduced into the sealed space through the gas injection head 20 to generate positive pressure. Under the action of positive pressure, the catalyst is blown from the powder discharge slot 27 into the conical powder discharge hole 25, and then discharged through the powder discharge port 19. The powder discharge port 19 can be connected to the powder delivery pipeline to provide stable powder supply for subsequent equipment. When the catalyst level in the storage silo 4 is insufficient, the electric discharge valve 8 on the connecting pipe at the lower end of the reserve silo 6 is opened, and the spare catalyst in the reserve silo 6 is replenished to the storage silo 4 through the connecting pipe to achieve stable supply.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Although this specification describes embodiments, not every embodiment contains only one technical solution. This method of description is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art.
