Description

Technical Field

[0001] This utility model relates to the field of perfluoroalkyl ethyl acrylate production technology, and in particular to a perfluoroalkyl ethyl acrylate production apparatus. Background Technology

[0002] Perfluoroalkyl ethyl acrylate is an important organic compound with wide applications in many fields. It is usually a colorless and transparent liquid with a density greater than water. It is insoluble in water but soluble in some organic solvents. It has low surface tension and can form a uniform protective film on the surface of materials. The production of perfluoroalkyl ethyl acrylate requires the use of a reaction device.

[0003] However, the existing equipment has the following shortcomings: When the existing equipment is in use, the chemical reaction inside the tank is often accompanied by the generation of gas. Since the inside of the tank is a sealed tank, it is difficult to release the generated gas. The gas accumulates inside the tank, increasing the internal gas pressure. This causes the gas to reverse and enter the material through the feed pipe when the equipment is feeding, thus contaminating the material.

[0004] Therefore, we propose a perfluoroalkyl ethyl acrylate production apparatus to address the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where the gas generated inside the equipment can easily cause an imbalance between the tank pressure and the external environment, making it difficult to quickly add materials when the gas enters the feed pipe during material feeding. Therefore, this invention proposes a perfluoroalkyl ethyl acrylate production device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a perfluoroalkyl ethyl acrylate production device, comprising a mounting frame, a tank, a feed pipe, a motor, and a discharge pipe. The tank is fixedly connected inside the mounting frame, the feed pipe is fixedly connected to the upper end of the tank, the discharge pipe is fixedly connected to the lower end of the tank, the motor is fixedly connected to the upper surface of the tank, and an exhaust device is fixedly installed at the upper end of the tank. The exhaust device includes an exhaust pipe and a connector. The connector is fixedly connected to the upper end of the tank, and the exhaust pipe is fixedly connected to the upper surface of the connector. A groove is formed inside the exhaust pipe near the connector, and a pressure plate is provided inside the groove. A sliding rod is fixedly connected to the upper end of the pressure plate.

[0007] Furthermore, a limiting frame is slidably connected to the surface of the slide rod, and the limiting frame is fixedly connected inside the exhaust pipe. By setting the limiting frame, the slide rod can be limited in movement, reducing the possibility of the slide rod deviating during use and making it difficult for the slide rod to move vertically on the pressure plate.

[0008] Furthermore, a fixing block is fixedly connected to the end of the slide rod away from the pressure plate, and a first spring is sleeved on the surface of the slide rod.

[0009] Furthermore, one end of the first spring is fixedly connected to the surface of the pressure plate, and the end of the first spring away from the pressure plate is fixedly connected to the lower end of the limiting frame. The first spring is provided to facilitate the application of a reset force to the pressure plate.

[0010] Furthermore, a filter device is provided inside the exhaust pipe. The filter device includes a mounting frame and a filter element. The mounting frame is slidably connected inside the exhaust pipe, and the filter element is fixedly connected inside the mounting frame. A connecting groove is provided at the end of the exhaust pipe away from the connector. A retaining ring is slidably connected inside the connecting groove. A positioning groove is provided on the side of the exhaust pipe, and a pull groove is provided on the side of the retaining ring. A pull block is slidably connected inside the pull groove. By setting the filter element, the emitted gas can be filtered, reducing the likelihood of harmful substances in the gas polluting the environment during equipment use.

[0011] Furthermore, a positioning rod is fixedly connected to the side of the pull block, and the positioning rod engages with the inside of the positioning groove. The positioning rod is provided to facilitate limiting the position of the pull block.

[0012] Furthermore, a second spring is fixedly connected to the end of the pull block near the pull groove, and the end of the second spring away from the pull block is fixedly connected to the inside of the pull groove.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, by setting up an exhaust device, the gas generated inside the tank is effectively discharged, which plays a role in maintaining the balance between the internal air pressure of the tank and the external environment. This reduces the situation where, during the use of existing equipment, chemical reactions inside the tank often produce gas. Since the tank is a sealed container, the generated gas is difficult to discharge, and the gas accumulates inside the tank, increasing the internal air pressure. This causes gas to reverse and enter the material through the feed pipe during material feeding, contaminating the material. This exhaust device, through the cooperation between the exhaust pipe and pressure plate and other components, achieves the function of discharging excess gas inside the tank, improving the practicality of the equipment.

[0014] In this invention, by setting up a filtration device, the emitted gas is effectively filtered, which plays a role in treating the emitted gas. This reduces the presence of harmful substances in the emitted gas when existing equipment is in use, as direct emission can easily pollute the environment. This filtration device, through the filter element, can adsorb harmful substances and emit clean gas, thus improving the cleanliness of the environment. Attached Figure Description

[0017] Please see Figures 1-5 This utility model provides a technical solution: a perfluoroalkyl ethyl acrylate production device, including a mounting frame 1, a tank 2, a feed pipe 3, a motor 4, and a discharge pipe 5. The tank 2 is fixedly connected inside the mounting frame 1. The tank 2 is made of corrosion-resistant special stainless steel, and the inner wall is treated with a special coating to resist corrosion from various chemicals during the perfluoroalkyl ethyl acrylate production process. The volume of the tank 2 is carefully designed according to production needs. Temperature and pressure sensors are installed inside to monitor the reaction environment in real time and ensure the safety and stability of the production process. At the same time, the tank 2 is wrapped with an insulation layer to effectively maintain the temperature conditions required for the reaction. The feed pipe 3 is fixedly connected to the upper end of the tank 2, the discharge pipe 5 is fixedly connected to the lower end of the tank 2, and the motor 4 is fixedly connected to the upper surface of the tank 2.

[0018] The specific setup and function of its exhaust device 6 and filter device 7 will be explained below.

[0019] In this embodiment: an exhaust device 6 is fixedly installed at the upper end of the tank body 2. The exhaust device 6 includes an exhaust pipe 61 and a connector 62. The connector 62 is fixedly connected to the upper end of the tank body 2, and the exhaust pipe 61 is fixedly connected to the upper surface of the connector 62. A groove 64 is opened inside the end of the exhaust pipe 61 near the connector 62. The shape and size of the groove 64 are precisely designed to fit tightly with the pressure plate 63, providing a stable installation base for the pressure plate 63, while ensuring that the pressure plate 63 can move flexibly under gas pressure. The pressure plate 63 is installed inside the groove 64. A slide rod 65 is fixedly connected to the upper end of the pressure plate 63. The pressure plate 63 is made of high-strength and elastic metal material, and its surface is polished. It fits tightly with the inner wall of the groove 64, which can ensure the sealing effect and allow it to rise and fall smoothly under gas pressure.

[0020] Specifically, the surface of the slide rod 65 is slidably connected to the limit bracket 67, and the limit bracket 67 is fixedly connected inside the exhaust pipe 61.

[0021] In this embodiment: by setting the limiting frame 67, the sliding rod 65 can be limited to move, which reduces the possibility of the sliding rod 65 deviating when moving during use, making it difficult for the sliding rod 65 to move vertically on the pressure plate 63.

[0022] Specifically, a fixing block 66 is fixedly connected to the end of the slide rod 65 away from the pressure plate 63, and a first spring 68 is sleeved on the surface of the slide rod 65.

[0023] Specifically, one end of the first spring 68 is fixedly connected to the surface of the pressure plate 63, and the other end of the first spring 68 away from the pressure plate 63 is fixedly connected to the lower end of the limit frame 67. The first spring 68 is provided to facilitate the application of a reset spring force to the pressure plate 63.

[0024] In this embodiment: Further, a filter device 7 is provided inside the exhaust pipe 61. The filter device 7 includes a mounting frame 71 and a filter element 72. The mounting frame 71 is slidably connected inside the exhaust pipe 61. The mounting frame 71 is made of a high-temperature resistant and corrosion-resistant metal material, and its shape and size are adapted to the internal space of the exhaust pipe 61 to ensure smooth sliding within the exhaust pipe 61. A sealing strip is provided on the edge of the mounting frame 71 to prevent unfiltered gas from escaping from the gap between the mounting frame 71 and the exhaust pipe 61. The filter element 72 is fixedly connected inside the mounting frame 71. The filter element 72 is made of a high-efficiency composite filter material with a large specific surface area and abundant microporous structure, which can effectively adsorb and filter gases. The filter element 72 removes harmful substances, dust particles, and other impurities. Its filtration efficiency has been rigorously tested and meets the purification requirements of the gas emitted during the production of perfluoroalkyl ethyl acrylate. A connecting groove 74 is provided at the end of the exhaust pipe 61 away from the connector 62. A retaining ring 73 is slidably connected inside the connecting groove 74. The retaining ring 73 is made of high-strength metal with a smooth surface and low friction with the inner wall of the connecting groove 74, making it easy to slide inside the connecting groove 74. The shape of the retaining ring 73 is reasonably designed so that it can fit tightly with the mounting frame 71 and firmly fix the mounting frame 71 inside the exhaust pipe 61. A positioning groove 75 is provided on the side of the exhaust pipe 61, and a pull groove 76 is provided on the side of the retaining ring 73. A pull block 77 is slidably connected inside the pull groove 76.

[0025] In this embodiment, by setting the filter element 72, the emitted gas can be filtered, reducing the likelihood of harmful substances in the gas polluting the environment during equipment use.

[0026] Specifically, a positioning rod 78 is fixedly connected to the side of the pull block 77. The positioning rod 78 is engaged with the inside of the positioning groove 75. The positioning rod 78 is provided to facilitate the limiting of the pull block 77.

[0027] Specifically, a second spring 79 is fixedly connected to one end of the pull block 77 near the pull groove 76, and the other end of the second spring 79 away from the pull block 77 is fixedly connected inside the pull groove 76.

[0028] Working principle: Perfluoroalkyl ethyl acrylate is produced through a reaction in tank 2. The gas generated in tank 2 enters the exhaust pipe 61 through connector 62. The gas pushes the pressure plate 63, causing the slide rod 65 to slide within the limit frame 67, compressing the first spring 68. When the gas pressure reaches a certain value, the pressure plate 63 rises, and the gas is discharged from the exhaust pipe 61. When the gas pressure in tank 2 drops, the first spring 68 returns to its original position, pushing the pressure plate 63 down and closing the exhaust pipe 61. This reduces the amount of outside air entering tank 2, ensuring a stable reaction environment inside tank 2. By setting up the exhaust device 6, the gas produced inside tank 2 is effectively vented. The exhaust device 6, through the coordinated operation of the exhaust pipe 61 and pressure plate 63, effectively discharges excess gas from the tank, maintaining a balance between the internal pressure and the external environment. This reduces the risk of gas generation during operation, as chemical reactions inside the tank often produce gas. Since the tank is a sealed container, the gas buildup inside increases the internal pressure, causing it to reverse and enter the material through the feed pipe 3 during feeding, contaminating the material. This exhaust device 6 improves the equipment's practicality by effectively discharging excess gas from the tank through the coordinated operation of the exhaust pipe 61 and pressure plate 63.

[0029] When the equipment is in use, the exhaust gas enters the mounting frame 71, and the filter element 72 filters impurities in the gas to ensure the purity of the exhaust gas. When the filter element 72 needs to be replaced, pull the pull block 77 to stretch the second spring 79 and generate elastic force, causing the positioning rod 78 to disengage from the positioning groove 75, removing the retaining ring 73 from the exhaust pipe 61, removing the mounting frame 71, replacing the filter element 72, and after replacement, reinserting the mounting frame 71 into the exhaust pipe 61, pushing the retaining ring 73 to make the positioning rod 78 engage with the positioning groove 75, fixing the retaining ring 73, ensuring the stability of the filter device 7, and allowing the filtered gas to be discharged from the exhaust pipe 61, reducing environmental pollution. By setting up the filter device 7, the exhaust gas is effectively filtered, playing a role in treating the exhaust gas, reducing the presence of harmful substances in the exhaust gas when existing equipment is in use, which can easily pollute the environment if directly discharged. This filter device 7, through the filter element 72, can adsorb harmful substances and discharge clean gas, improving the cleanliness of the environment.
