Description

Technical Field

[0001] This utility model relates to the field of copper etching solution production technology, specifically a raw material storage tank for copper etching solution production with a sealed anti-volatile structure. Background Technology

[0002] Raw material storage tanks for copper etching solution production can store corrosive liquid raw materials required for production in the short term, balancing the differences between production and supply rhythms and ensuring stable operation of the production line. For example, when raw material transportation is delayed or production demand fluctuates, the storage tanks can maintain process continuity. These tanks have corrosion-resistant structures that can isolate hazardous chemicals such as strong acids and alkalis, reducing the risk of leakage. Simultaneously, by stabilizing parameters such as liquid level and pressure, they assist the process system in maintaining a safe operating state.

[0003] However, the raw material storage tanks used in traditional copper etching solution production have the following drawbacks: The insufficient sealing of raw material storage tanks on the market can lead to leakage of etching solution during transportation or storage, which can not only cause material loss, but also pollute the environment or cause safety accidents. Summary of the Invention

[0004] The purpose of this utility model is to provide a raw material storage tank for the production of copper etching solution with a sealed and anti-volatile structure, so as to solve the problem mentioned in the background art that the insufficient sealing of the raw material storage tanks on the market can lead to leakage of etching solution during transportation or storage, which not only causes material loss, but may also pollute the environment or cause safety accidents.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a raw material storage tank for copper etching solution production with a sealed anti-volatile structure, comprising a bottom shell, a top cover being snapped onto the top of the bottom shell, a sealing component being fitted at the connection between the bottom shell and the top cover, mounting shells being fixedly installed on both sides of the inner wall of the top cover, mounting grooves being provided on one side of the bottom end of each of the two mounting shells, connecting grooves being provided on one side of the inner wall of each of the two mounting grooves, connecting springs being fixedly installed on one side of the inner wall of each of the two connecting grooves, and sliding blocks being fixedly installed at one end of each of the two connecting springs and slidably connected to the connecting grooves, mounting rods being fixedly installed on both sides of the top of the bottom shell, and grooves being provided on the opposite sides of each of the two mounting rods.

[0006] Preferably, the two grooves are respectively provided corresponding to the two sliding blocks. The mounting rod is inserted into the mounting groove, the groove and the sliding block are engaged, the sliding block slides relative to the connecting groove, and the sliding block squeezes the connecting spring from one side. The connecting spring is elastic, and the elastic deformation of the connecting spring buffers the squeezing force, so that the sliding block and the groove fit tightly.

[0007] Preferably, the sealing assembly includes a sealing ring and a first ring piece. One end of the outer side of the sealing ring is slidably connected to the inner side of the first ring piece, and the other end of the outer side of the sealing ring is slidably connected to a second ring piece. One end of the first ring piece has a groove, and one end of the second ring piece has a retaining post fixedly installed. The groove and the retaining post are correspondingly arranged. Assembly seats are fixedly installed on the surfaces of the first and second ring pieces, and a return spring is fixedly installed between the two assembly seats. A pin is rotatably connected between the first and second ring pieces. When an external force is applied to the sealing ring, the retaining post slides out relative to the groove, and the distance between the two assembly seats changes. The two assembly seats pull the return spring from both sides. The return spring is elastic, and the elastic deformation of the return spring buffers the pulling force, facilitating the return of the ring piece.

[0008] Preferably, the inner side of the sealing ring is connected to the bottom shell, and the sealing ring seals the connection between the bottom shell and the top cover.

[0009] Preferably, connecting plates are fixedly installed at the bottom ends of both sides of the bottom shell, and height screws are rotatably connected to the top ends of the two connecting plates. A pressure plate is threaded between the two height screws, and a fixing nut is threaded at the connection between the two height screws and the pressure plate. The middle part of the bottom end of the pressure plate contacts the top end of the top cover. When the user rotates the height screw, the threads on the surface of the height screw match the threads on the inner wall of the pressure plate, so the pressure plate moves relative to the height screw. The pressure plate presses the top cover from the top to prevent the top cover from loosening from the bottom shell. The user rotates the fixing nut to fix the height screw and the pressure plate together.

[0010] Preferably, a first positioning plate is fixedly installed at the bottom of both sides of the top cover, and a second positioning plate is fixedly installed at the top of both sides of the bottom shell. An assembly screw is threaded between the two first positioning plates and the two second positioning plates. A locking nut is threaded at both ends of the two assembly screws. After the user fastens the top cover onto the bottom shell, the user rotates the two locking nuts. The threads on the inner wall of the locking nuts match the threads on the surface of the assembly screws. Therefore, the locking nuts rotate and translate relative to the assembly screws, fixing the assembly screws between the first positioning plate and the second positioning plate.

[0011] Preferably, support legs are fixedly installed on both sides of the bottom end of the bottom shell, and a pressure gauge extending into the bottom shell is fixedly installed on the surface of the bottom shell, allowing the user to understand the pressure inside the raw material storage tank by visually observing the pressure gauge.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. By setting up a sealing assembly, the sealing ring and the ring plate seal from the outside of the sealing point, improving the sealing performance of the device and avoiding leakage of the etching solution during transportation or storage due to insufficient sealing, thereby improving its safety in use. 2. By setting a pressure plate and a height screw, the user can rotate the height screw to press the pressure plate onto the top cover from the top, preventing the top cover from coming loose from the bottom shell and preventing the etching solution inside the tank from coming into contact with oxygen or moisture in the air, which could lead to oxidation and failure of the components, affecting etching efficiency and the quality of the finished product.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] Please see Figure 1-4 This utility model provides a raw material storage tank for copper etching solution production with a sealed anti-volatile structure, including a bottom shell 1, a top cover 2 that is snapped onto the top of the bottom shell 1, a sealing component 11 that is fitted at the connection between the bottom shell 1 and the top cover 2, mounting shells 14 that are fixedly installed on both sides of the inner wall of the top cover 2, mounting grooves 15 that are opened on one side of the bottom end of each of the two mounting shells 14, connecting grooves 20 that are opened on one side of the inner wall of each of the two mounting grooves 15, connecting springs 19 that are fixedly installed on one side of the inner wall of each of the two connecting grooves 20, and sliding blocks 18 that are slidably connected to the connecting grooves 20 that are fixedly installed at one end of each of the two connecting springs 19, and mounting rods 16 that are fixedly installed on both sides of the top of the bottom shell 1, and grooves 17 that are opened on the opposite sides of each of the two mounting rods 16.

[0017] Two grooves 17 are respectively set with two sliding blocks 18. The mounting rod 16 is inserted into the mounting groove 15. The grooves 17 and sliding blocks 18 are engaged. The sliding blocks 18 slide relative to the connecting groove 20. The sliding blocks 18 press the connecting spring 19 from one side. The connecting spring 19 is elastic. The elastic deformation of the connecting spring 19 buffers the pressing force, so that the sliding blocks 18 and the grooves 17 fit tightly.

[0018] The sealing assembly 11 includes a sealing ring 111 and a first annular piece 112. One end of the outer side of the sealing ring 111 is slidably connected to the inner side of the first annular piece 112, and the other end of the outer side of the sealing ring 111 is slidably connected to a second annular piece 113. One end of the first annular piece 112 has a groove 114, and one end of the second annular piece 113 is fixedly mounted with a retaining post 115. The groove 114 and the retaining post 115 are correspondingly arranged. Assembly bases 1 are fixedly mounted on the surfaces of both the first annular piece 112 and the second annular piece 113. 16. A return spring 117 is fixedly installed between the two assembly seats 116. A pin is rotatably connected between the first ring plate 112 and the second ring plate 113. When an external force is applied to the sealing ring 111, the locking pin 115 slides out relative to the locking groove 114, and the distance between the two assembly seats 116 changes. The two assembly seats 116 pull the return spring 117 from both sides. The return spring 117 is elastic. The return spring 117 undergoes elastic deformation to buffer the pulling force, which facilitates the ring plate to return to its original position.

[0019] The inner side of the sealing ring 111 is connected to the bottom shell 1, and the sealing ring 111 seals the connection between the bottom shell 1 and the top cover 2.

[0020] Connecting plates 3 are fixedly installed on the bottom ends of both sides of the bottom shell 1. Height screws 6 are rotatably connected to the top of the two connecting plates 3. A pressure plate 7 is threaded between the two height screws 6. A fixing nut 8 is threaded at the connection between the two height screws 6 and the pressure plate 7. The middle part of the bottom end of the pressure plate 7 contacts the top end of the top cover 2. When the user rotates the height screws 6, the threads on the surface of the height screws 6 match the threads on the inner wall of the pressure plate 7, so the pressure plate 7 moves relative to the height screws 6. The pressure plate 7 presses the top cover 2 from the top to prevent the top cover 2 from loosening from the bottom shell 1. The user rotates the fixing nut 8 to fix the height screws 6 and the pressure plate 7 together.

[0021] First positioning plates 9 are fixedly installed at the bottom ends of both sides of the top cover 2, and second positioning plates 10 are fixedly installed at the top ends of both sides of the bottom shell 1. Assembly screws 12 are threadedly connected between the two first positioning plates 9 and the two second positioning plates 10. Locking nuts 13 are threadedly connected to both ends of the two assembly screws 12. After the user fastens the top cover 2 onto the bottom shell 1, the user rotates the two locking nuts 13. The threads on the inner wall of the locking nuts 13 match the threads on the surface of the assembly screws 12, so the locking nuts 13 rotate and translate relative to the assembly screws 12, fixing the assembly screws 12 between the first positioning plates 9 and the second positioning plates 10.

[0022] Support legs 5 are fixedly installed on both sides of the bottom end of the bottom shell 1. A pressure gauge 4 extending into the bottom shell 1 is fixedly installed on the surface of the bottom shell 1. Users can understand the pressure inside the raw material storage tank by visually observing the pressure gauge 4.

[0023] In this embodiment, during use: the mounting rod 16 is inserted into the mounting groove 15, the groove 17 engages with the sliding block 18, the sliding block 18 slides relative to the connecting groove 20, and the sliding block 18 presses against the connecting spring 19 from one side. The connecting spring 19 is elastic, and its elastic deformation buffers the pressing force, making the sliding block 18 and the groove 17 fit tightly together, completing the assembly of the top cover 2 and the bottom shell 1. After the user fastens the top cover 2 onto the bottom shell 1, the user rotates the two locking nuts 13. The threads on the inner wall of the locking nuts 13 match the threads on the surface of the assembly screw 12, so the locking nuts 13 rotate and translate relative to the assembly screw 12, fixing the assembly screw 12 to the first positioning plate. Between 9 and the second positioning plate 10, the user rotates the height screw 6. The thread on the surface of the height screw 6 matches the thread on the inner wall of the pressure plate 7, so the pressure plate 7 moves relative to the height screw 6. The pressure plate 7 presses the top cover 2 from the top to prevent the top cover 2 from loosening from the bottom shell 1. The user rotates the fixing nut 8 to fix the height screw 6 and the pressure plate 7 together. When an external force is applied to the sealing ring 111, the locking post 115 slides out relative to the locking groove 114, and the distance between the two assembly seats 116 changes. The two assembly seats 116 pull the return spring 117 from both sides. The return spring 117 is elastic. The return spring 117 undergoes elastic deformation to buffer the pulling force, which facilitates the ring plate to return to its original position.
