Description

Technical Field

[0001] This invention belongs to the field of aromatic hydrocarbon ammonia oxidation catalyst preparation technology, specifically relating to an aromatic hydrocarbon ammonia oxidation catalyst raw material mixing and dissolution device based on multi-link hybridization. Background Technology

[0002] Aromatic hydrocarbon ammonia oxidation catalysts are a class of substances that play a key role in chemical production. They are specifically designed to promote the oxidation reaction of aromatic compounds with ammonia and oxygen. These catalysts are typically composed of multiple active components and supports. The active components often include metal elements such as vanadium, molybdenum, and titanium. They work synergistically to provide the active sites required for the catalytic reaction. Supports such as alumina and silica provide good dispersion and support for the active components, which helps to improve the stability and service life of the catalyst.

[0003] In the preparation and processing of aromatic ammonia oxidation catalysts, it is necessary to mix and dissolve the raw materials, dissolving metal salts (such as nitrates and sulfates) in water or organic solvents. However, existing mixing and dissolving devices mostly use multiple small rods for stirring and mixing, which cannot achieve the purpose of rapid dissolution and mixing. The raw materials are easily agglomerated at the bottom of the device, resulting in poor mixing and dissolution effect of aromatic ammonia oxidation catalyst raw materials. To address this, we propose an aromatic ammonia oxidation catalyst raw material mixing and dissolution device based on multi-link mixing. Utility Model Content

[0004] The purpose of this invention is to provide a mixing and dissolving device for aromatic hydrocarbon ammonia oxidation catalyst feedstock based on multi-link hybridization, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mixing and dissolving device for aromatic hydrocarbon ammonia oxidation catalyst feedstock based on multi-link hybridization, comprising,

[0006] The outer shell has a mixing and dissolving cylinder inside, and the upper and lower parts of the outer shell are respectively provided with a feed inlet and a discharge outlet;

[0007] A multi-link stirring assembly, wherein the outer shell is provided with a multi-link stirring assembly extending into the interior of the mixing and dissolving cylinder;

[0008] A feeding and dispersing assembly is disposed on the upper part of the multi-link stirring assembly, corresponding to the inner side of the mixing and dissolving cylinder.

[0009] Preferably, an inclined ring plate is provided between the outer shell and the mixing and dissolving cylinder.

[0010] Preferably, the feed inlet is inclined toward the feed dispersing component.

[0011] Preferably, an electromagnetic switch valve is provided on the discharge port.

[0012] Preferably, the outer side of the outer shell is provided with ring-shaped support rods.

[0013] Preferably, the multi-link stirring assembly includes a drive motor, a transmission rod, a main stirring rod, a side connecting rod, and a secondary stirring rod;

[0014] The drive motor is located at the upper end of the outer shell. The transmission rod is connected to the output end of the drive motor and extends through the outer shell into the interior of the mixing and dissolving cylinder. Several main stirring rods are arranged at equal intervals on the transmission rod at the inner side of the mixing and dissolving cylinder. The bottom of the transmission rod is provided with side connecting rods symmetrically surrounding the outside of the main stirring rods. The side connecting rods are provided with auxiliary stirring rods that are alternately distributed with the main stirring rods.

[0015] Preferably, the side linkage rod and the uppermost ring of the main stirring rod are connected by a retaining ring.

[0016] Preferably, the bottom of the side linkage rod is located in an arc-shaped structure that matches the bottom of the mixing and dissolving cylinder, and the bottom of the side linkage rod is provided with a scraping protrusion.

[0017] Preferably, the feeding and dispersing assembly includes a dispersing disc and a separator bar;

[0018] The dispersing disc is mounted on the transmission rod above the fixing ring, and the dispersing disc is provided with equally spaced dividing strips.

[0019] Preferably, the dispersion disk has an umbrella-shaped structure.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] This invention features a multi-link stirring assembly and a feeding and dispersing assembly. During use, the aromatic hydrocarbon ammonia oxidation catalyst raw material and solvent are fed into the outer casing through the inlet and fall onto the dispersing disc. When the drive motor rotates the transmission rod, the separators on the dispersing disc effectively and evenly separate the aromatic hydrocarbon ammonia oxidation catalyst raw material and solvent. The rotation of the dispersing disc further disperses the raw material and solvent evenly into the mixing and dissolving cylinder, improving the dispersion uniformity and facilitating mixing and dissolution. Simultaneously, the transmission rod drives the main stirring rod, side connecting rod, and auxiliary stirring rod to rotate synchronously, ensuring that the main stirring rod, side connecting rod, and auxiliary stirring rod... The aromatic hydrocarbon ammonia oxidation catalyst raw material and solvent are mixed and stirred by a multi-linkage mechanism. At the same time, the scraping protrusion at the bottom of the side linkage scrapes the aromatic hydrocarbon ammonia oxidation catalyst raw material at the bottom of the mixing and dissolving cylinder, participating in the gentle stirring and dissolution. This ensures that all aromatic hydrocarbon ammonia oxidation catalyst raw materials and solvents in the mixing and dissolving cylinder are mixed and dissolved in an all-round manner, reducing the occurrence of insufficient dissolution of aromatic hydrocarbon ammonia oxidation catalyst raw materials adhering to the inner wall of the mixing and dissolving cylinder, and improving the mixing and dissolution efficiency and effect of aromatic hydrocarbon ammonia oxidation catalyst raw materials. After the aromatic hydrocarbon ammonia oxidation catalyst raw materials are mixed and dissolved, the mixed and dissolved raw materials are output from the outlet by controlling the electromagnetic switch valve.

[0030] Please see Figures 1-6 The present invention provides a multi-link hybrid aromatic ammonia oxidation catalyst feedstock mixing and dissolving device, comprising:

[0031] The outer shell 1 has annular support rods 8 on its outer side for supporting and fixing the mixing and dissolving device. The mixing and dissolving cylinder 2 is located inside the outer shell 1. An inclined ring plate 9 is provided between the outer shell 1 and the mixing and dissolving cylinder 2 to ensure a seamless connection between the outer shell 1 and the mixing and dissolving cylinder 2, preventing materials from entering the cavity between the outer shell 1 and the mixing and dissolving cylinder 2. The upper and lower parts of the outer shell 1 are respectively provided with a feed inlet 3 and a discharge outlet 4. The feed inlet 3 is inclined towards the feed dispersion component 6 to facilitate the conveying of the aromatic ammonia oxidation catalyst raw material and solvent to the feed dispersion component 6. An electromagnetic switch valve 7 is provided on the discharge outlet 4 to facilitate the control of the output of the aromatic ammonia oxidation catalyst mixed and dissolved raw material.

[0032] A multi-link stirring assembly 5 is provided on the outer shell 1, extending into the mixing and dissolving cylinder 2. The multi-link stirring assembly 5 includes a drive motor 501, a transmission rod 502, a main stirring rod 503, a side connecting rod 504, and an auxiliary stirring rod 505. The drive motor 501 is located at the upper end of the outer shell 1. The transmission rod 502 is connected to the output end of the drive motor 501 and extends through the outer shell 1 into the mixing and dissolving cylinder 2. The transmission rod 502 is positioned at an inner position within the mixing and dissolving cylinder 2. There are several rings of equally spaced main stirring rods 503. The bottom of the transmission rod 502 is provided with side connecting rods 504 symmetrically surrounding the outside of the main stirring rods 503. The side connecting rods 504 are provided with auxiliary stirring rods 505 that are alternately distributed with the main stirring rods 503. The side connecting rods 504 and the uppermost ring of main stirring rods 503 are connected by a fixing ring 506 to improve the structural strength. The bottom of the side connecting rods 504 is located in an arc-shaped structure that matches the bottom of the inner side of the mixing and dissolving cylinder 2. The bottom of the side connecting rods 504 is provided with scraping protrusions 507.

[0033] The feeding and dispersing assembly 6 is located on the upper part of the multi-link stirring assembly 5, corresponding to the inner side of the mixing and dissolving cylinder 2. The feeding and dispersing assembly 6 includes a dispersing disk 601 and a separator bar 602. The dispersing disk 601 is located on the transmission rod 502 above the fixing ring 506. The dispersing disk 601 is provided with equally spaced separator bars 602. The dispersing disk 601 has an umbrella-shaped structure.

[0034] This invention features a multi-link stirring assembly 5 and a feeding and dispersing assembly 6. During use, the aromatic hydrocarbon ammonia oxidation catalyst raw material and solvent are fed into the outer casing 1 through the feed inlet 3 and fall onto the dispersing disc 601. When the drive motor 501 drives the transmission rod 502 to rotate, the separator strips 602 on the dispersing disc 601 effectively and uniformly separate the aromatic hydrocarbon ammonia oxidation catalyst raw material and solvent. The rotation of the dispersing disc 601 further disperses the aromatic hydrocarbon ammonia oxidation catalyst raw material and solvent evenly into the mixing and dissolving cylinder 2, improving the dispersion uniformity of the aromatic hydrocarbon ammonia oxidation catalyst raw material and solvent and facilitating mixing and dissolution. Simultaneously, the transmission rod 502 drives the main stirring rod 503, the side connecting rod 504, and the auxiliary stirring rod 505 to rotate synchronously, causing the main stirring rod 503... The side linkage rod 504 and the auxiliary stirring rod 505 perform multi-link mixing and stirring of the aromatic ammonia oxidation catalyst raw material and solvent. At the same time, the scraping protrusion 507 at the bottom of the side linkage rod 504 scrapes the aromatic ammonia oxidation catalyst raw material at the bottom of the mixing and dissolving cylinder 2, participating in the gentle stirring and dissolution. This allows for comprehensive mixing and dissolution of all aromatic ammonia oxidation catalyst raw materials and solvent within the mixing and dissolution cylinder 2, reducing the occurrence of insufficient dissolution of aromatic ammonia oxidation catalyst raw materials adhering to the inner wall of the mixing and dissolution cylinder 2, and improving the mixing and dissolution efficiency and effect of the aromatic ammonia oxidation catalyst raw materials. After the aromatic ammonia oxidation catalyst raw materials are mixed and dissolved, the mixed and dissolved raw materials are output from the discharge port 4 by controlling the electromagnetic switch valve 7.

[0035] In summary, the method of using the aromatic hydrocarbon ammonia oxidation catalyst raw material mixing and dissolving device based on multi-link hybridization provided in this embodiment is as follows: During use, the aromatic hydrocarbon ammonia oxidation catalyst raw material and solvent are conveyed into the outer shell 1 through the feed inlet 3 and fall onto the dispersion disc 601. When the drive motor 501 drives the transmission rod 502 to rotate, the separator 602 on the dispersion disc 601 effectively and uniformly separates the aromatic hydrocarbon ammonia oxidation catalyst raw material and solvent. Through the rotation of the dispersion disc 601, the aromatic hydrocarbon ammonia oxidation catalyst raw material and solvent are evenly dispersed into the mixing and dissolving cylinder 2, improving the dispersion uniformity of the aromatic hydrocarbon ammonia oxidation catalyst raw material and solvent, facilitating mixing and dissolving. At the same time, the transmission rod 501... 2. The main stirring rod 503, the side connecting rod 504, and the auxiliary stirring rod 505 rotate synchronously, so that the main stirring rod 503, the side connecting rod 504, and the auxiliary stirring rod 505 perform multi-link mixing and stirring of the aromatic ammonia oxidation catalyst raw material and solvent. At the same time, the scraping protrusion 507 at the bottom of the side connecting rod 504 scrapes the aromatic ammonia oxidation catalyst raw material at the bottom of the mixing and dissolving cylinder 2, and participates in the gentle stirring and dissolution. In this way, all the aromatic ammonia oxidation catalyst raw materials and solvents in the mixing and dissolving cylinder 2 are mixed, stirred and dissolved in an all-round way. After the aromatic ammonia oxidation catalyst raw materials are mixed and dissolved, the mixed and dissolved raw materials of the aromatic ammonia oxidation catalyst are output from the discharge port 4 through the electromagnetic switch valve 7.
