[0003] In the production process of polysilane, the catalytic conversion of polysilane is a key step, and its reaction efficiency and product quality have a significant impact on the performance of the final product. Traditional polysilane catalytic conversion devices have many shortcomings in material handling and reaction processes.
[0004] Insufficient mixing and contact between the catalyst and the materials often results in slow reaction rates and low conversion rates, failing to meet the demands of modern large-scale, high-efficiency production. When entering the post-reaction product separation stage, accurately and rapidly separating the products from unreacted materials and catalysts within the complex reaction mixture is a challenging task. Traditional equipment often struggles with effective separation, leading to limited product purity. Furthermore, some traditional equipment exhibits poor stability during long-term operation, and material blockage frequently occurs during catalysis, hindering the normal flow of the catalyst and affecting reaction efficiency. When critical components are corroded by harmful substances in polysilane, the stability and lifespan of the equipment are severely impacted, thus restricting the sustainable development of polysilane production. Therefore, this application proposes a polysilane catalytic conversion device with product separation capabilities to solve the above problems and promote the upgrading and progress of the polysilane industry.

[0032] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0033] This utility model discloses a polysilane catalytic conversion device with product separation function.
[0034] Example 1:
[0035] According to the appendix Figure 1-4 As shown, the catalyst furnace 1 is equipped with a booster pump 2 on one side of the catalyst furnace 1. The top of the catalyst furnace 1 is provided with a feed inlet for adding materials into the catalyst furnace 1. The booster pump 2 is used to provide power for the delivery of the catalyst liquid. Under the action of the booster pump 2, the catalyst liquid can be stably and continuously entered into the catalyst furnace 1 to participate in the reaction.
[0036] A feeding assembly is provided in the middle of the interior of the catalytic furnace 1. The feeding assembly includes a hollow shaft 3 and multiple pusher frames 5. The hollow shaft 3 is connected to the booster pump 2. The hollow shaft 3 stores the catalytic liquid under the action of the booster pump 2. The pusher frames 5 are used to spray out the catalytic liquid in the hollow shaft 3 to react with the material in the catalytic furnace 1.
[0037] A product separation assembly 4 is provided at the bottom of the catalytic furnace 1. The product separation assembly 4 includes:
[0038] The filter screen 41 is installed on the inner wall of the catalytic furnace 1. The filter screen 41 is used to intercept unreacted materials and catalyst particles, and only allows the product liquid after the reaction to pass through.
[0039] The collection tank 42 is located directly below the filter screen plate 41 and is used to temporarily store the separated product liquid.
[0040] The discharge pipe 43 is inserted into the collection tank 42. The discharge pipe 43 leads the product liquid in the collection tank 42 out of the catalytic furnace 1 for further processing or storage.
[0041] Catalytic furnace 1 is made of high-temperature and corrosion-resistant materials. Catalytic furnace 1 is the core reaction vessel of the entire device. It is made of high-temperature and corrosion-resistant materials to adapt to the high-temperature and high-pressure environment in the polysilane catalytic conversion process.
[0042] The booster pump 2 is connected to a feeding pipe 21 and a conveying pipe 22 at both ends. The feeding pipe 21 is connected to an external storage device, and the conveying pipe 22 connects the booster pump 2 to the hollow shaft 3. The feeding pipe 21 is used to receive the catalytic liquid from the external storage device, and the conveying pipe 22 is used to convey the pressurized catalytic liquid to the hollow shaft 3 inside the catalytic furnace 1.
[0043] Hollow shaft 3 penetrates catalytic furnace 1. Both ends of hollow shaft 3 are equipped with sealed bearings, which are connected to the side wall of catalytic furnace 1. The sealed bearings are used to ensure the sealing and stability of hollow shaft 3 during rotation.
[0044] The top end of the hollow shaft 3 is outside the catalytic furnace 1, and a drive shaft is provided at the outer end of the hollow shaft 3. The hollow shaft 3 is connected to the drive mechanism through the drive shaft.
[0045] The hollow shaft 3 rotates under the action of the transmission shaft and the drive mechanism. Under the rotation of the hollow shaft 3, the catalytic liquid in the hollow shaft 3 is sprayed into the catalytic furnace 1 to mix with the material in the catalytic furnace 1, thereby improving the mixing effect of the catalytic liquid and the material.
[0046] Example 2:
[0047] According to the appendix Figure 1-4 As shown, the system includes a catalytic furnace 1, a booster pump 2 installed on one side of the catalytic furnace 1, a feeding assembly located in the middle of the interior of the catalytic furnace 1, the feeding assembly including a hollow shaft 3 and multiple pusher frames 5, the hollow shaft 3 being connected to the booster pump 2, and a product separation assembly 4 located at the bottom of the catalytic furnace 1, the product separation assembly 4 including:
[0048] The filter screen 41 is installed on the inner wall of the catalytic furnace 1;
[0049] The collection tank 42 is located directly below the filter screen plate 41;
[0050] The discharge pipe 43 is inserted into the collection tank 42.
[0051] The pusher frame 5 is set on both sides of the hollow shaft 3. Each pusher frame 5 is provided with a feeding hole 51, which is used to spray out the catalyst liquid to react with the material.
[0052] An anti-blocking block 52 is installed on the inner side of the filling hole 51. The anti-blocking block 52 is used to support the exposed or reposition the filling hole 51.
[0053] A spring telescopic rod 53 is fixedly connected to one side of the anti-blocking block 52. The spring telescopic rod 53 is installed in the pusher frame 5. Under the action of the spring telescopic rod 53, it cooperates with the anti-blocking block 52 to push out or reset and seal the feeding hole 51, so as to prevent the material from blocking the feeding hole 51 and affecting the normal progress of the reaction.
[0054] Working principle: Before use, check whether the connections of each component of the device are tight and whether the sealing performance is good. Pay special attention to the sealing of key parts such as catalytic furnace 1, booster pump 2, feeding pipe 21, conveying pipe 22 and product separation component 4 to ensure that there is no leakage.
[0055] An appropriate amount of catalytic liquid is injected into the storage tank of the booster pump 2 through the feed pipe 21. At the same time, the composition and ratio of the catalytic liquid are set according to the requirements of the polysilane catalytic conversion reaction.
[0056] The material to be reacted is added from the feed port at the top of the catalytic furnace 1. The amount and speed of material addition are controlled to avoid the reaction effect being affected by too much or too little material.
[0057] When the booster pump 2 is started, the catalyst is transported to the hollow shaft 3 through the delivery pipe 22 under the action of the booster pump 2. As the pressure inside the hollow shaft 3 gradually increases, the anti-blocking block 52 is pushed up and exposed to the filling hole 51 under the pressure.
[0058] Under the action of the drive mechanism, the hollow shaft 3 starts to rotate slowly. Under the action of the pusher frame 5, the catalyst liquid is evenly sprayed onto the material through the feeding hole 51 opened in the pusher frame 5, so that the catalyst liquid and the material can fully contact each other and undergo catalytic conversion reaction. During this process, the spraying speed and spraying range of the catalyst liquid can be controlled by adjusting the rotation speed of the hollow shaft 3, thereby optimizing the reaction conditions.
[0059] After the reaction is complete, the discharge port at the bottom of the catalytic furnace 1 is opened, and the mixture after the reaction falls onto the filter screen 41 in the product separation component 4 by gravity.
[0060] The filter plate 41 performs preliminary filtration of the mixture, intercepting unreacted materials and catalyst particles, allowing only the product liquid after the reaction to pass through and flow into the collection tank 42.
[0061] Once the product liquid in the collection tank 42 reaches a certain amount, the valve on the discharge pipe 43 is opened to lead the product liquid out of the device and send it to the subsequent refining process for further purification and treatment to obtain high-purity polysilane product.
[0062] After completing one reaction and product separation cycle, the operation of booster pump 2 and hollow shaft 3 is stopped, and the residual material in catalytic furnace 1 is cleaned to prepare for the next reaction.
[0063] At the same time, the anti-clogging block 52 and filter screen 41 and other components are inspected and cleaned to ensure their good performance, and replaced in time if any damage is found.
[0064] 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 claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
