Description

Technical Field

[0001] The present invention relates to the technical field of polycrystalline silicon carbon preparation equipment, and more specifically to a polycrystalline silicon carbon preparation equipment for synthesizing a specific shape from recrystallized waste materials. Background Art

[0002] Recrystallization waste usually refers to the residual material produced in the recrystallization process that has not been effectively utilized or needs to be further processed. Recrystallization is a physical or chemical process that achieves the purpose of purification or separation by dissolving the substance in a solvent and then recrystallizing it. In this process, the main target substance will precipitate from the solution and form crystals, while the remaining non-target substances will also form crystals but are regarded as waste due to their different structures from the target crystals. In order to make the waste effectively utilized, a polycrystalline silicon carbon preparation device is required. It synthesizes polycrystalline silicon carbide materials with specific shapes and sizes by controlling crystal growth conditions such as temperature, pressure and gas. The polycrystalline silicon preparation device usually includes a material handling device, a reduction furnace, a cooling system, and an automation and monitoring system.

[0003] The shortcomings of the existing recrystallization waste synthesis of specific shape polycrystalline silicon carbon preparation device:

[0004] First, the waste material that precipitates from the solution and forms crystals is in a crystalline state. Since the waste material is naturally cooled, its crystals will appear as larger particles. Larger particles mean that the contact area between the unit mass of waste material and the reaction medium is reduced, which may lead to a slower reaction rate, thereby reducing the overall reaction efficiency and output.

[0005] Second: During the preparation of polycrystalline silicon carbon, waste materials and other compounds will produce high-temperature reactions. In this process, in addition to the target product silicon carbide, potentially harmful waste gases may also be generated. These waste gases are directly discharged into the laboratory without treatment. Although these waste gases are harmless to the human body in the short term, they can cause suffocation risks at high concentrations and also have long-term impacts on the environment. Summary of the invention

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a device for preparing polycrystalline silicon carbon of a specific shape by synthesizing polycrystalline silicon carbon from recrystallized waste materials to solve the problems existing in the above-mentioned background technology.

The transmission rod drives the round block so that the first driving rod and the second driving rod drive the storage box to rotate on the grinding plate, which can effectively grind the crystalline waste, which is beneficial for completing the reaction in a shorter time, thereby improving the reaction efficiency.

[0009] Furthermore, the outer surface of the grinding plate is fixedly connected with an edge, the middle part is movably connected with a baffle, the top of the baffle is provided with a grinding groove, the bottom of the baffle is fixedly connected with a folding block, the front of the folding block is fixedly connected with a second motor, and the baffle is folded by using the second motor to drive the folding block, so that the ground crystalline waste can be quickly dropped into the reduction furnace to improve work efficiency.

[0010] Furthermore, leakage holes are formed at the bottom of the material storage box, a transfer trough is fixedly connected to the bottom of the material storage box, and a strip groove is provided at the bottom of the transfer trough, so that the crystallized waste can fall onto the grinding disc.

[0011] Furthermore, the pressing mechanism includes a mounting frame, a guide column, a first spring, a pressure plate and a lifting block. The bottom of the mounting frame is fixedly connected to the guide column, the outer surface of the guide column is movably connected to the first spring, the bottom of the first spring is fixedly connected to the pressure plate, and the outer surface of the pressure plate is movably connected to a storage box.

[0012] Furthermore, the purification device includes a first fan, a second fan, a check valve, a Z-shaped groove, a replacement groove, a sealing block, a catalytic decomposition box and a catalytic layer. One end of the purification device is fixedly connected to the first fan, the other end of the purification device is fixedly connected to the second fan, a check valve is provided on one side of the second fan, the top and bottom of the check valve are fixedly connected to the purification device, a Z-shaped groove is provided on the inner surface of the purification device, a replacement groove is provided on the other side of the Z-shaped groove, the inner surface of the replacement groove is movably connected to a sealing block, the middle part of the purification device is fixedly connected to the catalytic decomposition box, and the inner surface of the catalytic decomposition box is movably connected to the catalytic layer, so that the treated exhaust gas emissions will greatly reduce the odor and harmful gas concentration in the laboratory, provide a cleaner and safer working environment for the staff, and help improve work efficiency and reduce the occurrence of occupational diseases.

[0014] Technical effects and advantages of the present invention:

[0015] 1. In the present invention, when the volume of the crystallized waste needs to be reduced, tweezers are used to clamp the lifting block and lift it upward. At this time, the first spring begins to contract, and the setting of the guide column can make the position of the first spring relatively fixed and will not deviate. Then, the crystallized waste is placed under the pressure plate and the tweezers are released. The first spring rebounds and presses the crystallized waste into the storage box through the pressure plate. At this time, the storage box is full of crystallized waste and a leakage hole is opened at the bottom. At this time, the crystallized waste passes through the leakage hole to the transfer groove and the strip groove below to reach the grinding plate. At this time, the first motor is started to make the first conical tooth start to rotate. When the first conical tooth starts to rotate, the second conical tooth starts to rotate. When the second conical tooth starts to rotate, the transmission rod starts to rotate. At this time, the round block on the top of the transmission rod drives the first driving rod to rotate, and the first driving rod is connected to the second driving rod so that the second driving rod drives the storage box to move on the grinding plate. At this time, the crystallized waste material rubs between the grinding plate and the storage box, causing the volume of the crystallized waste material to gradually decrease. Subsequently, the second motor is started to rotate the folding block and fold the baffle downward to cause the crystallized waste material to fall into the reduction furnace, which is conducive to completing the reaction in a shorter time, thereby improving the reaction efficiency. At the same time, since the chances of adverse factors such as side reactions and decomposition of reactants are reduced, the purity and yield of the product will also be improved.

[0016] 2. In the present invention, when the crystallized waste generates a large amount of harmful gas during the reaction, the first fan and the second fan are started to transmit the harmful gas in the reduction furnace to the inside of the purification device. At this time, the harmful air is initially filtered through the filter. Then, the gas continues to move upward to the catalytic decomposition box, decomposes the harmful gas through the catalytic layer and finally transmits it to the outside; when the filter in the filter device needs to be replaced, the bolts on the sealing block are removed and the sealing block is removed, and then the clamp is aligned with the Z-shaped groove and inserted into the groove. At this time, the second spring is unfolded in the Z-shaped groove so that the filter can be quickly installed in the purification device. The treated exhaust gas emissions will greatly reduce the odor and harmful gas concentration in the laboratory, provide a cleaner and safer working environment for the staff, and help improve work efficiency and reduce the occurrence of occupational diseases.
