Description

Technical Field

[0001] This utility model relates to the technical field of catalyst production equipment, specifically to a catalytic reaction device using a highly active catalyst. Background Technology

[0002] Highly active catalysts are a class of catalysts that can significantly reduce the activation energy and accelerate the reaction rate in chemical reactions, and can effectively promote the reaction under mild conditions such as lower temperatures. They are of great significance in many fields, serving as key basic materials in modern chemical industry, energy industry, and environmental protection. In the chemical industry, highly active catalysts can improve reaction efficiency, reduce the occurrence of side reactions, thereby increasing product purity and yield, and reducing production costs. In the pharmaceutical industry, when preparing high-purity drug components, highly active and selective catalysts can precisely promote the target reaction and reduce the generation of impurities. In the energy industry, in fuel cells, highly active catalysts can accelerate chemical reactions at the electrodes, improving the energy conversion efficiency of the battery; in petroleum processing, highly active catalytic cracking catalysts can rapidly convert heavy oil into light oil at lower temperatures, improving production efficiency and product quality. In the field of environmental protection, it can be used for automobile exhaust purification. The highly active three-way catalyst can promote the rapid conversion of carbon monoxide, hydrocarbons and nitrogen oxides in exhaust gas into harmless substances, reducing the emission of harmful gases. In industrial waste gas treatment, the highly active catalyst can accelerate the decomposition or transformation of pollutants in waste gas, reducing air pollution.

[0003] A catalyst is a substance that alters the reaction rate but not the overall reaction. The effect of a catalyst in a chemical reaction is called catalysis, and catalysts are also known as catalysts in industry. During catalyst production, a stirring device is used to ensure thorough mixing of materials. However, current stirring devices, due to the fixed positions of the stirring shaft and blades, cannot adequately mix materials at the bottom and higher positions of the mixing tank. Therefore, this paper proposes a stirring device for catalyst production.

[0004] A prior art patent, CN212640200U, discloses a solution including a reaction chamber and a motor. A gantry support is fixedly connected to the reaction chamber, and the motor is fixedly mounted on the gantry support. Two stirring mechanisms are provided between the reaction chamber and the gantry support, and the two stirring mechanisms are meshed. The end of the motor's output shaft rotates through the horizontal part of the gantry support and is fixedly connected to one of the stirring mechanisms. A lifting mechanism is provided on the vertical side wall of the gantry support, and a slidable unblocking mechanism is provided on the lifting mechanism, which is located at the top of the reaction chamber. The lifting mechanism and one of the stirring mechanisms are connected by the same transmission mechanism. An inlet pipe and an outlet pipe are connected to the side wall of the reaction chamber, and a filter plate and a solenoid valve are fixedly installed in the outlet pipe. This utility model can not only effectively recover the catalyst, but also effectively improve the utilization effect of the catalyst.

[0005] Existing devices, including those mentioned above, have gradually revealed shortcomings in the technology with use, mainly in the following aspects:

[0006] First, existing catalyst reaction devices, when mixing various additives, are limited by the single flow pattern of materials within the tank, which cannot guarantee rapid mixing of various materials and reduces the reaction efficiency of the catalyst.

[0007] Secondly, existing catalyst production equipment requires regular cleaning of the inner cavity after the materials are mixed. Due to the limited volume of the cleaning structure, a large amount of space inside the reactor is occupied, reducing the volume of the reactor and affecting the catalytic efficiency of the catalyst.

[0008] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0009] To address the shortcomings of existing technologies, this invention provides a highly active catalyst reaction device to overcome the problem that traditional catalyst reaction devices, when mixing various additives, are limited by the single flow pattern of materials within the tank, which prevents rapid mixing of various materials and reduces catalyst reaction efficiency.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A highly active catalyst catalytic reaction apparatus includes a reaction vessel. A main shaft is vertically rotatable inside the reaction vessel. Several feed cylinders are rotatably mounted around the main shaft on the inner top surface of the reaction vessel. These feed cylinders rotate synchronously with the main shaft via a top linkage structure. A distribution plate is horizontally fixed to the lower end of each feed cylinder. Several distribution holes are circumferentially formed on the side wall of each feed cylinder near its lower end.

[0012] Two stirring structures are mounted side-by-side and rotatably on the inner bottom surface of the reactor. The two stirring structures rotate synchronously with the main shaft via a bottom linkage structure.

[0013] A side stirring plate is fixedly connected to the main shaft and rubs against the inner wall of the reactor. The top of the side stirring plate is provided with an inner wall cleaning structure.

[0014] As an optimized solution, the inner wall cleaning structure includes a water storage cavity opened near the upper end of the side stirring plate, and a number of spray holes are opened obliquely from top to bottom on the side wall of the side stirring plate, facing the inner wall of the reactor.

[0015] As an optimized solution, the side stirring plate is fixed to the main shaft by several connecting rods arranged in parallel from top to bottom. The upper end of the main shaft is provided with a liquid inlet channel, and the uppermost connecting rod is provided with a connecting channel that connects the liquid inlet channel to the spray hole.

[0016] As an optimized solution, the upper end of the feed cylinder and the upper end of the main shaft both extend above the reactor. The top linkage structure includes a top drive gear fixed to the main shaft, and each feed cylinder is fixed with a top driven gear that meshes with the top drive gear.

[0017] As an optimized solution, an additive inlet cylinder is rotatably inserted into the upper port of the feed cylinder, and a cleaning liquid inlet cylinder connected to the liquid inlet channel is rotatably inserted into the upper port of the main shaft.

[0018] As an optimized solution, the material distribution disc is provided with a plurality of material distribution blades around the feed cylinder, and each material distribution hole is located in the area between adjacent material distribution blades.

[0019] As an optimized solution, the stirring structure includes a rotating shaft vertically rotatably mounted at the bottom of the reactor, with a plurality of stirring blades surrounding the upper end of the rotating shaft.

[0020] As an optimized solution, the lower end of the rotating shaft and the lower end of the main shaft both extend to the bottom of the reactor. The bottom linkage structure includes a bottom drive gear fixed to the main shaft, and each rotating shaft is fixed with a bottom driven gear that meshes with the bottom drive gear.

[0021] As an optimized solution, a drive motor is fixedly connected to the outer bottom surface of the reactor, and the output end of the drive motor meshes with the bottom drive gear via a gear.

[0022] As an optimized solution, a material discharge cylinder is fixedly connected to the side wall of the reactor near the bottom.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] The main shaft is driven to rotate by a drive motor, which in turn drives two stirring structures to rotate using a bottom linkage structure. Several feed cylinders at the top are driven to rotate using a top linkage structure. Various materials are added into the feed cylinders through the additive inlet cylinder. The rotating feed cylinders disperse the materials under the action of the distribution plate and distribution blades, allowing them to fall evenly into the reactor, thus improving the uniformity of material dispersion. The rotation of the two stirring structures and the side stirring plates ensures thorough stirring of the materials in the reactor, increasing the mobility of the materials in the reactor and improving the reaction efficiency of the catalyst.

[0025] When cleaning the inside of the reactor is required, the cleaning liquid is added into the inlet channel along the cleaning liquid inlet cylinder, and sprayed onto the inner wall of the reactor through the spray holes at the top of the side stirring blades. As the side stirring blades rotate, the material adhering to the side wall of the reactor is cleaned. The cleaning mechanism is set inside the main shaft and the side cleaning plate, which can reduce the occupation of the reactor volume, ensure the rapid mixing of various materials, and improve the reaction efficiency of the catalyst.

Detailed Implementation

[0030] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0031] like Figure 1 and Figure 2 As shown, the highly active catalyst catalytic reaction device includes a reaction vessel 1. A main shaft 2 is vertically rotatable inside the reaction vessel 1. Several feed cylinders 10 are rotatably mounted around the main shaft 2 on the inner top surface of the reaction vessel 1. These feed cylinders 10 rotate synchronously with the main shaft 2 via a top linkage structure. A distribution plate 11 is horizontally fixed to the lower end of each feed cylinder 10. Several distribution holes 13 are circumferentially opened on the side wall of the feed cylinder 10 near its lower end.

[0032] Two stirring structures are mounted side-by-side and rotate on the inner bottom surface of the reactor 1. The two stirring structures rotate synchronously with the main shaft 2 via a bottom linkage structure.

[0033] A side stirring plate 4 is fixedly connected to the main shaft 2 and rubs against the inner wall of the reactor 1. The top of the side stirring plate 4 is provided with an inner wall cleaning structure.

[0034] The inner wall cleaning structure includes a water storage cavity 5 opened near the upper end of the side stirring plate 4, and several spray holes 6 are opened from top to bottom on the side wall of the side stirring plate 4, facing the inner wall of the reactor 1.

[0035] The side stirring plate 4 is fixed to the main shaft 2 by several connecting rods 3 arranged in parallel from top to bottom. The upper end of the main shaft 2 is provided with a liquid inlet channel 8, and the uppermost connecting rod 3 is provided with a connecting channel 7 that connects the liquid inlet channel 8 with the spray hole 6.

[0036] The upper end of the feed cylinder 10 and the upper end of the main shaft 2 both extend to the top of the reactor. The top linkage structure includes a top drive gear 16 fixed to the main shaft 2, and each feed cylinder 10 is fixed with a top driven gear 15 that meshes with the top drive gear 16.

[0037] The upper end of the feed cylinder 10 is rotatably inserted with an additive inlet cylinder 14, and the upper end of the main shaft 2 is rotatably inserted with a cleaning fluid inlet cylinder 9 that is connected to the liquid inlet channel 8.

[0038] The material distribution plate 11 is surrounded by several material distribution blades 12, and each material distribution hole 13 is located in the area between adjacent material distribution blades 12.

[0039] The stirring structure includes a rotating shaft 22 that is vertically and rotatably installed at the bottom of the reactor, with several stirring blades 17 surrounding the upper end of the rotating shaft 22.

[0040] The lower end of the rotating shaft 22 and the lower end of the main shaft 2 both extend to the bottom of the reactor. The bottom linkage structure includes a bottom drive gear 19 fixed to the main shaft 2, and each rotating shaft 22 is fixed with a bottom driven gear 18 that meshes with the bottom drive gear 19.

[0041] A drive motor 21 is fixedly attached to the outer bottom surface of the reactor. The output end of the drive motor 21 meshes with the bottom drive gear 19 via a gear.

[0042] A material discharge cylinder 20 is fixedly attached to the side wall near the bottom of the reactor.

[0043] The working principle of this device is as follows:

[0044] The drive motor 21 drives the main shaft 2 to rotate, the bottom linkage structure drives the two stirring structures to rotate, and the top linkage structure drives the several feed cylinders 10 at the top to rotate. Various materials are added into the feed cylinders 10 through the additive inlet cylinder 14. The feed cylinders 10 rotate, and the materials are dispersed under the action of the distribution plate 11 and the distribution blades 12, so that they fall evenly into the reactor, which improves the uniformity of material dispersion when added. The rotation of the two stirring structures and the side stirring plate 4 fully stirs the materials in the reactor, increases the mobility of the materials in the reactor, and improves the reaction efficiency of the catalyst.

[0045] When it is necessary to clean the inside of the reactor, the cleaning liquid is added into the liquid inlet channel 8 along the cleaning liquid inlet cylinder 9, and sprayed onto the inner wall of the reactor through the spray hole 6 at the top of the side stirring blade 17. As the side stirring blade 17 rotates, the material adhering to the side wall of the reactor is cleaned. The cleaning mechanism is set inside the main shaft 2 and the side cleaning plate, which can reduce the occupation of the reactor volume, ensure the rapid mixing of various materials, and improve the reaction efficiency of the catalyst.
