Abstract
Description
Technical Field
[0001] This utility model relates to the field of trichlorosilane storage technology, specifically a trichlorosilane storage tank. Background Technology
[0002] Trichlorosilane storage tanks are closed containers specifically designed for storing trichlorosilane, a highly hazardous chemical. They must meet core requirements such as corrosion resistance, leak prevention, and risk control. They are key facilities for ensuring safety and process stability in the production, transportation, and use of trichlorosilane, and are widely used in industries such as photovoltaics (polysilicon preparation), semiconductors, and organosilicon chemicals.
[0003] Existing trichlorosilane storage tanks experience liquid sloshing during operation due to vehicle start-stop cycles. This sloshing causes the liquid to collide with the tank body, easily generating static electricity. This necessitates grounding the metal components, but grounding requires charge to flow into the earth, leaving residual charge. If this charge accumulates excessively, it can easily generate electric sparks, posing a hazard and failing to meet user needs. To address these issues, a technological innovation is proposed based on existing trichlorosilane storage tanks. Utility Model Content
[0004] The purpose of this invention is to provide a trichlorosilane storage tank to solve the problem mentioned in the background art that the general tanks cannot adequately meet people's usage needs.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a trichlorosilane storage tank, comprising a tank assembly, a cooling assembly mounted on the tank assembly, and a power offset assembly installed inside the tank assembly. The power offset assembly includes a rotating worm gear, a first spring, a rear fixing block, and a central bearing. The central bearing is mounted in the middle of the rotating worm gear, and the first spring is connected to the left and right sides of the central bearing. The rear fixing block is connected to the end of the first spring away from the central bearing.
[0006] Furthermore, a communication component is installed on top of the tank assembly, and a storage component is wrapped around the outside of the tank assembly.
[0007] Furthermore, the tank assembly includes a storage pipe, a feed pipe, and a sealing cap, with the feed pipe connected to the upper end of the storage pipe and the sealing cap installed at the upper end of the feed pipe.
[0008] Furthermore, the cooling assembly includes a condenser unit and a delivery pipe, and the inlet and outlet of the condenser unit are connected to the delivery pipe.
[0009] Furthermore, the cooling assembly also includes a connecting pipe and a cooling pipe, and the end of the delivery pipe away from the condenser unit is connected to the connecting pipe, and the connecting pipe is connected to the cooling pipe.
[0010] Furthermore, the connecting component includes a connecting pipe and a pressure valve, and the pressure valve is installed on the connecting pipe.
[0011] Furthermore, the storage assembly includes a storage box, a second spring, and a piston plate, with the second spring installed inside the storage box and the piston plate connected above the second spring.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the device has a power consumption function, thereby reducing the impact generated during the liquid flow process and thus reducing the occurrence of static electricity; the device has a gas pressure relief structure to protect the inside of the device and prevent damage caused by excessive internal gas pressure. 1. When this utility model is in operation, the flow of liquid inside the equipment will cause the rotating worm gear to rotate. The power generated by the liquid flow is transmitted to the rotating worm gear, causing it to rotate. This rotational motion can consume the impact force between the liquid and the tank components, which not only stabilizes the operation of the equipment but also reduces the possibility of electric charge generated by friction, thus reducing safety hazards. In addition, to protect the rotating worm gear from the instantaneous impact force of the liquid, this utility model is designed with an elastic structure consisting of a central bearing, a first spring, and a rear fixing block. The central bearing is connected to the rear fixing block through the first spring to form a buffer system. When the instantaneous impact force of the liquid acts on the rotating worm gear, this elastic structure can buffer, disperse, and absorb the impact force, preventing damage to the rotating worm gear, extending the service life of the equipment, and ensuring stable operation.
[0013] 2. When the liquid inside the device of this utility model vaporizes, the generated gas is transported to a dedicated storage component for storage by means of a specially designed connecting component. In this way, the storage component plays a pressure-sharing role, effectively distributing and regulating the gas pressure inside the tank component. This design can avoid excessive gas generation during liquid vaporization, which would cause a rapid increase in the internal pressure of the equipment and affect the stability and normal operation of the equipment. This mechanism ensures the safety of equipment transportation, extends its service life, and improves the safety and reliability of the system. Attached Figure Description

[0016] like Figure 1 and Figure 4 As shown, a trichlorosilane storage tank includes a tank assembly 1, a cooling assembly 2 installed on the tank assembly 1, and a power cancellation assembly 3 installed inside the tank assembly 1. The power cancellation assembly 3 includes a rotating worm gear 301, a first spring 302, a rear fixing block 303, and a central bearing 304. The central bearing 304 is installed in the middle of the rotating worm gear 301, and the first spring 302 is connected to the left and right sides of the central bearing 304. The rear fixing block 303 is connected to the end of the first spring 302 away from the central bearing 304. During operation, the flow of liquid inside the equipment inevitably causes the rotating worm gear 301 to rotate. Specifically, when the liquid flows inside the equipment, the power it generates is transmitted to the rotating worm gear 301, causing it to start rotating. In this way, the rotation of the rotating worm gear 301 can effectively dissipate the impact force between the liquid and the tank assembly 1. This dissipation of impact force not only helps to stabilize the operating state of the equipment, but also significantly reduces the possibility of electrical charge generated by friction, thereby reducing safety hazards during equipment operation.
[0017] Furthermore, to further protect the rotating worm gear 301 from the instantaneous impact of liquid, this invention designs an elastic structure. This elastic structure consists of a central bearing 304, a first spring 302, and a rear fixing block 303. Specifically, the central bearing 304 is connected to the rear fixing block 303 through the first spring 302, forming an elastic buffer system. When the instantaneous impact of liquid acts on the rotating worm gear 301, this elastic structure can buffer the rotating worm gear 301 to a certain extent, effectively dispersing and absorbing the impact force, avoiding damage to the rotating worm gear 301 due to excessive impact force, thereby extending the service life of the equipment and ensuring its stable operation.
[0018] like Figure 2 As shown, a connecting component 4 is installed on the top of the tank assembly 1, and a storage component 5 is wrapped around the outside of the tank assembly 1. When the liquid inside the device vaporizes, the generated gas is effectively transported to a dedicated storage component 5 for proper storage via a specially designed connecting component 4. In this way, the storage component 5 can fully utilize its pressure-sharing function to effectively distribute and regulate the gas pressure inside the tank component 1. This design effectively prevents the liquid inside the equipment from generating excessive gas due to vaporization, which could lead to a sharp increase in internal pressure and affect the overall stability and normal operation of the equipment. This mechanism ensures the safety of the equipment during transportation, extends its service life, and improves the safety and reliability of the system.
[0019] like Figure 1 As shown, the tank assembly 1 includes a storage pipe 101, a feed pipe 102 and a sealing cap 103, and the upper end of the storage pipe 101 is connected to the feed pipe 102, and the upper end of the feed pipe 102 is equipped with the sealing cap 103. The feed pipe 102 on the storage pipe 101 is integrated with the storage pipe 101 to ensure a tight and seamless connection. A sealing structure is specially provided between the feed pipe 102 and the sealing cap 103. This structure may include, but is not limited to, sealing elements such as sealing gaskets. With this design, when the sealing cap 103 is installed in place, it can effectively seal the feed pipe 102, thereby preventing liquid from leaking from the feed pipe 102 during storage or transmission, ensuring the safety and reliability of the entire system, and avoiding various potential problems caused by liquid leakage.
[0020] like Figure 1 and Figure 3 As shown, the cooling assembly 2 includes a condenser unit 201 and a conveying pipe 202, and the inlet and outlet of the condenser unit 201 are connected to the conveying pipe 202. The cooling assembly 2 also includes a connecting pipe 203 and a cooling pipe 204, and the end of the conveying pipe 202 away from the condenser unit 201 is connected to the connecting pipe 203, and the connecting pipe 203 is connected to the cooling pipe 204. The condensing unit 201 includes a compressor, an evaporator, and an expansion valve, etc. The connecting pipe 203 connects multiple cooling pipes 204 together, so that multiple cooling pipes 204 work together.
[0021] like Figure 2 As shown, the connecting component 4 includes a connecting pipe 401 and a pressure valve 402, and the pressure valve 402 is installed on the connecting pipe 401. The pressure valve 402 can open after the internal pressure of the storage tube 101 reaches a certain level, thereby transporting the vaporized gas through the connecting pipe 401 to the storage component 5 for storage.
[0022] like Figure 2As shown, the storage component 5 includes a storage box 501, a second spring 502 and a piston plate 503, and the second spring 502 is installed inside the storage box 501, and the piston plate 503 is connected above the second spring 502. The piston plate 503 forms an elastic structure with the storage box 501 through the second spring 502. The elastic structure allows the air inside the storage box 501 to be discharged as much as possible when there is no gas stored inside, so as to avoid the storage box 501 being mixed with air when it is working, which could easily cause an explosion.
[0023] Working principle: When using the trichlorosilane storage tank, first install the equipment into the transport container, then open the sealing cover 103 and inject sufficient trichlorosilane into the storage tube 101, filling it almost to the brim. Then close the sealing cover 103, and the equipment is ready for use. This equipment can be used for storage in the trichlorosilane purification process, and also for transportation, that is, transporting trichlorosilane from one step of the purification process to another processing step. During the operation of the equipment, the condenser unit 201 generates cooling liquid that is transported through the conveyor. Pipe 202 delivers the liquid to cooling pipe 204 to cool the inside of storage pipe 101. If the liquid vaporizes during the use of the equipment, the pressure inside storage pipe 101 will increase when the vaporization reaches a certain amount. The gas is then delivered to storage component 5 through connecting component 4 to reduce the pressure in storage pipe 101 and ensure the normal operation of the equipment. During transportation, the liquid flow will impact the rotating worm gear 301, causing the rotating worm gear 301 to rotate and consume the impact force of the liquid. The elasticity of the first spring 302 can also provide auxiliary buffering for the rotating worm gear 301.
