Description

Technical Field

[0001] This utility model relates to the field of catalyst addition technology, and in particular to a catalyst addition device for hydrogen peroxide decomposition reaction. Background Technology

[0002] Hydrogen peroxide decomposes slowly at room temperature. Adding a catalyst can significantly reduce the activation energy of the reaction, allowing more reactant molecules to collide and react effectively under lower energy conditions, thereby greatly accelerating the decomposition rate of hydrogen peroxide. In industrial production, catalysts can be used to rapidly decompose hydrogen peroxide in a short time, generating large amounts of oxygen and water to meet the needs of large-scale production.

[0003] For example, CN218012665U discloses a safe hydrogen peroxide production oxidation device, including an oxidation device body, a workbench fixedly connected to the lower part of the oxidation device body, support legs fixedly connected to the four corner edges of the lower part of the workbench, a control panel fixedly installed on the upper part of the workbench, an inlet and an outlet fixedly connected to the left and right sides of the oxidation device body respectively, a catalyst addition pipe fixedly connected to the upper part of the oxidation device body, a first fixing ring fixedly connected to the inside of the catalyst addition pipe near the side of the oxidation device body, and a second fixing ring fixedly connected to the other end of the catalyst addition pipe.

[0004] However, in the existing technology, adding a catalyst during the decomposition of hydrogen peroxide increases the intensity of the reaction, which can easily affect the operator's judgment on the amount to be added. Since the catalyst is in powder form, the judgment is affected and it is easy to add too much catalyst. In addition, during the addition process, the gas produced by the reaction can easily come into contact with the catalyst that has not yet been added, which can easily contaminate some of the catalyst. Utility Model Content

[0005] The purpose of this invention is to solve the problems in the prior art where the judgment is affected, which can easily lead to excessive addition of catalyst, and during the addition process, the gas produced by the reaction can easily come into contact with the catalyst that has not yet been added, which can easily contaminate part of the catalyst. Therefore, a catalyst addition device for hydrogen peroxide decomposition reaction is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a catalyst addition device for hydrogen peroxide decomposition reaction, comprising an addition cylinder, the top of which is covered with a sealing plug, a rotating rod rotatably mounted on the cylinder wall, one end of which is fixedly connected to a partition plate, the partition plate being located inside the addition cylinder and having a shape adapted to the shape of the addition cylinder, the other end of which is fixedly connected to a disc, and driven rods being fixedly mounted at equal intervals on one side of the disc.

[0007] Preferably, a limiting ring is fixedly installed on the outer wall of the adding cylinder, and a connecting bracket is fixedly connected to the edge of the limiting ring.

[0008] Preferably, a turntable is rotatably mounted on one end of the connecting bracket, and a vertical plate is fixedly mounted on the top of the connecting bracket.

[0009] Preferably, a servo motor is fixedly installed on one side of the vertical plate, and the output shaft of the servo motor is fixedly connected to the turntable.

[0010] Preferably, a support bar is fixedly installed on the outer wall of the turntable, and the thickness of the support bar is equal to the distance between two adjacent driven rods.

[0011] Preferably, a diamond-shaped protrusion is provided at the midpoint between the two support bars, and the center line of the diamond-shaped protrusion is flush with the upper surface of the support bar.

[0012] Preferably, the end of the support bar is provided with an inclined surface.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting a rotatable partition plate inside the adding cylinder, when adding the catalyst, the rotating disc drives the partition plate through the rotating rod, so that the partition plate rotates inside the adding cylinder, allowing the catalyst to fall into the hydrogen peroxide. When the partition plate rotates half a revolution, it will block the adding cylinder again. At this time, external substances will not enter the space above the partition plate and contaminate the catalyst. This not only controls the amount of catalyst added, but also prevents the catalyst from being contaminated.

[0015] 2. In this utility model, a servo motor is used to drive the turntable. The edge of the turntable is provided with support bars and diamond-shaped protrusions. When the support bars contact the driven rod, the disc cannot rotate. At this time, the partition plate will block the adding cylinder. When the diamond-shaped protrusions contact the driven rod, they will push the driven rod to make the disc rotate synchronously, so as to achieve the purpose of sealing the adding cylinder at time.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a catalyst addition device for hydrogen peroxide decomposition reaction, including an addition cylinder 1, a sealing plug 2 covering the top of the addition cylinder 1, a rotating rod 7 rotatably mounted on the cylinder wall of the addition cylinder 1, a partition plate 8 fixedly connected to one end of the rotating rod 7, the partition plate 8 being located inside the addition cylinder 1, and the shape of the partition plate 8 being adapted to the shape of the addition cylinder 1, and a disc 9 fixedly connected to the other end of the rotating rod 7, with driven rods 10 fixedly installed at equal intervals on one side of the disc 9;

[0024] A limiting ring 3 is fixedly installed on the outer wall of the adding cylinder 1. A connecting bracket 4 is fixedly connected to the edge of the limiting ring 3. A turntable 11 is rotatably installed on one end of the connecting bracket 4. A vertical plate 5 is fixedly installed on the top of the connecting bracket 4. A servo motor 6 is fixedly installed on one side of the vertical plate 5. The output shaft of the servo motor 6 is fixedly connected to the turntable 11.

[0025] The specific settings and functions of this embodiment are described below. The addition cylinder 1 is used to store palladium catalyst. Opening the sealing plug 2 at the top of the addition cylinder 1 allows palladium catalyst to be injected into it. When no catalyst is added, the partition plate 8 is horizontal inside the addition cylinder 1, and the palladium catalyst will remain above the partition plate 8. When catalyst needs to be added, the servo motor 6 is started. The servo motor 6 drives the turntable 11, which pushes the driven rod 10 to make the disc 9 rotate. Since the partition plate 8 and the disc 9 are fixedly connected by the rotating rod 7, the partition plate 8 rotates once for every one rotation of the disc 9. When the partition plate 8 rotates, the catalyst will fall into the hydrogen peroxide. When the partition plate 8 rotates half a rotation, it will block the addition cylinder 1 again. At this time, external substances will not enter the space above the partition plate 8 and contaminate the catalyst, and the palladium catalyst in the addition cylinder 1 will no longer fall. This controls the amount of catalyst added and also prevents the catalyst from being contaminated.

[0026] The servo motor 6 is installed on the side of the vertical plate 5. The vertical plate 5 is connected to the connecting bracket 4 to ensure the stability of the servo motor 6. The connecting bracket 4 is fixedly connected to the limiting ring 3 on the outer wall of the adding cylinder 1. The positions of the turntable 11 and the rotating rod 7 are also determined simultaneously to avoid structural misalignment.

[0027] Example 2: Figure 2 , Figure 3 and Figure 4 As shown, a support bar 12 is fixedly installed on the outer wall of the turntable 11. The thickness of the support bar 12 is equal to the distance between two adjacent driven rods 10. A rhomboid protrusion 13 is provided at the midpoint between the two support bars 12. The center line of the rhomboid protrusion 13 is flush with the upper surface of the support bar 12. An inclined surface 14 is provided at the end of the support bar 12.

[0028] The overall effect of this embodiment is that the support bar 12 on the outer wall of the turntable 11 is used to determine the position of the driven rod 10. During the rotation of the turntable 11, the support bar 12 will first turn away from the two driven rods 10. During this turning away process, the driven rod 10 is limited by the support bar 12 and will not be displaced. After the support bar 12 turns away from the driven rod 10, the diamond-shaped protrusion 13 will contact the driven rod 10. The center line of the diamond-shaped protrusion 13 is flush with the upper surface of the support bar 12, ensuring that the diamond-shaped protrusion 13 can use the inclined surface to push the driven rod 10 without affecting the movement of other driven rods 10. During this process, the disc 9 will be pushed and the partition plate 8 will rotate accordingly. After the diamond-shaped protrusion 13 turns away from the driven rod 10, the support bar 12 will re-enter between the two adjacent driven rods 10, and the existence of the inclined surface 14 can ensure that the support bar 12 can be properly connected with the driven rod 10.

[0029] The usage and working principle of this device are as follows: The addition cylinder 1 is used to store palladium catalyst. Opening the sealing plug 2 at the top of the addition cylinder 1 allows palladium catalyst to be injected into it. When no catalyst is added, the partition plate 8 is horizontal inside the addition cylinder 1, and the palladium catalyst will remain above the partition plate 8. When catalyst needs to be added, the servo motor 6 is started, and the servo motor 6 drives the turntable 11. During the rotation of the turntable 11, the support bar 12 will first rotate away from the two driven rods 10. During this rotation process, the driven rods 10 are limited by the support bar 12 and will not be displaced.

[0030] After the support bar 12 rotates away from the driven rod 10, the diamond-shaped protrusion 13 will contact the driven rod 10. The diamond-shaped protrusion 13 uses the inclined surface to push the driven rod 10, thereby pushing the disc 9. The disc 9 drives the partition plate 8 through the rotating rod 7. When the partition plate 8 rotates, the catalyst will fall into the hydrogen peroxide. When the partition plate 8 rotates half a turn, it will block the addition cylinder 1 again. At this time, the diamond-shaped protrusion 13 will also rotate away from the driven rod 10.

[0031] After this, the support bar 12 will re-enter between the two adjacent driven rods 10, re-fix the disc 9, and use the partition plate 8 to block the internal space of the addition cylinder 1 again. At this time, external substances will not enter the space above the partition plate 8 to contaminate the catalyst, and the palladium catalyst in the addition cylinder 1 will no longer fall down. This can control the amount of catalyst added while preventing the catalyst from being contaminated.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
