Description

Technical Field

[0001] This invention relates to the field of anti-volatile packaging device technology, specifically an anti-volatile packaging device for isocyanate production. Background Technology

[0002] The main function of anti-volatile packaging devices in isocyanate production is to reduce the volatilization of isocyanates during production, storage, and transportation, thereby reducing environmental pollution and ensuring production safety. Such devices typically include sealed containers, dedicated valves, and sealing systems, which can effectively control the release of isocyanates and ensure their safe storage and transfer in a closed environment.

[0003] Currently, existing anti-volatile encapsulation devices have poor sealing performance during use. The protective shell on top of the encapsulation device is mostly installed inside the encapsulation device by threaded connection. This connection method has poor sealing performance during use and may cause isocyanate to volatilize.

[0004] Combining the above issues, we find that the existing anti-volatile encapsulation devices for isocyanate production on the market are difficult to simultaneously avoid the problems mentioned above. Even if they can be solved, they require the assistance of external tools, thus failing to achieve the desired effect. Therefore, we propose an anti-volatile encapsulation device for isocyanate production. Summary of the Invention

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Example 1: Please refer to Figures 1-10 The present invention provides a technical solution: an anti-volatile packaging device for isocyanate production, including a packaging cylinder 1, a packaging mechanism 2 disposed above the packaging cylinder 1, and a water sealing mechanism 3 disposed above the packaging cylinder 1.

[0042] The packaging mechanism 2 includes a fastening packaging unit 21, which is disposed on the outside of the packaging cylinder 1 and can fasten the packaging shell.

[0043] As a further limitation of the present invention, the fastening and sealing unit 21 includes a sealing cover 2106, the outer surface of which contacts the inner wall of the sealing cylinder 1. A cross plate 2104 is provided above the sealing cover 2106, and a drive shaft 2115 is fixedly connected to the bottom surface of the cross plate 2104. A partition cylinder 2114 is fixedly connected to the inner wall of the sealing cover 2106. The outer surface of the drive shaft 2115 is slidably connected to the inside of the partition cylinder 2114, and a drive plate 211 is fixedly connected to the bottom end of the drive shaft 2115. 8. A limiting plate 2110 is fixedly connected to the inner wall of the encapsulation cover 2106. The left side of the transmission plate 2118 contacts the right side of the limiting plate 2110. A transmission rope 2103 is fixedly connected to the bottom surface of the transmission plate 2118. A fixing block 2102 is fixedly connected to the outer surface of the encapsulation cover 2106. The right end of the transmission rope 2103 passes through the encapsulation cover 2106 and the fixing block 2102 in sequence and extends into the interior of the fixing block 2102. The outer surface of the transmission rope 2103 is slidably connected to the fixing block 2102. Inside the inner wall of the sealing cover 2106, two return springs 2123 are fixedly connected to the inner bottom wall of the fixing block 2102. A lifting plate 2121 is fixedly connected to the top of both return springs 2123. A locking block 2113 is fixedly connected to the inner wall of the lifting plate 2121. The outer surface of the locking block 2113 is slidably connected to the inside of the fixing block 2102. The bottom end of the locking block 2113 is fixedly connected to the top end of the transmission rope 2103. A limit ring 2101 is fixedly connected to the inner wall of the sealing cylinder 1. A slot 2122 is provided on the bottom surface of 1. The outer surface of the card block 2113 is engaged with the inside of the slot 2122. The upper surface of the fixing block 2102 is in contact with the bottom surface of the limiting ring 2101. A fastening and sealing unit 21 is provided. The fastening and sealing unit 21 can limit the sealing cover 2106 and provide a downward force to the sealing cover 2106, so that the sealing cover 2106 can be in close contact with the sealing cylinder 1, avoiding the problem that the sealing cover 2106 will not be able to achieve a good sealing effect due to external forces.

[0044] Please see Figure 1 and Figure 5The upper surface of the encapsulation cover 2106 has two first T-shaped grooves 2112. Each first T-shaped groove 2112 has a first T-shaped block 2111 slidably connected inside. Each first T-shaped block 2111 has a support block 2105 fixedly connected to its upper surface. The bottom surface of each support block 2105 is in contact with the upper surface of the encapsulation cover 2106. By setting the first T-shaped grooves 2112, the first T-shaped blocks 2111, and the support blocks 2105, and by utilizing the limiting relationship between the first T-shaped blocks 2111 and the first T-shaped grooves 2112, it can be ensured that the support blocks 2105 only move along a predetermined path.

[0045] Please see Figure 7 The inner top wall of the encapsulation cover 2106 is fixedly connected to two fixing plates 2109. The inner walls of the two fixing plates 2109 are rotatably connected to a rolling cylinder 2119. The outer surface of the rolling cylinder 2119 is in contact with the outer surface of the transmission rope 2103. By providing the rolling cylinder 2119, the corner position of the transmission rope 2103 can be limited.

[0046] Please see Figure 7 The upper surface of the limiting plate 2110 is provided with a second T-shaped groove 2116, and a second T-shaped block 2117 is slidably connected inside the second T-shaped groove 2116. The right side of the second T-shaped block 2117 is fixedly connected to the left side of the transmission plate 2118. By providing the second T-shaped block 2117 and the second T-shaped groove 2116, it can be ensured that the transmission plate 2118 only moves up and down.

[0047] Please see Figure 2 Two connecting frames 2108 are fixedly connected to the outer surface of the encapsulation cylinder 1. Each connecting frame 2108 has a rotating handle 2107 rotatably connected to its inner wall. By setting the connecting frame 2108 and the rotating handle 2107, the connecting frame 2108 can fix the rotating handle 2107, and the rotating handle 2107 can easily apply tension to the encapsulation cylinder 1.

[0048] Please see Figure 1 The inner wall of the cross plate 2104 is rotatably connected to two rotating cylinders 2120. The outer surface of each rotating cylinder 2120 is in contact with the upper surface of the support block 2105. By providing the rotating cylinders 2120, the friction between the cross plate 2104 and the support block 2105 can be reduced.

[0049] The specific implementation of this embodiment is as follows: When this device is needed, the support block 2105 can be pushed to move towards the position of the cross plate 2104. In addition, due to the presence of the rotating cylinder 2120, the friction between the support block 2105 and the cross plate 2104 is reduced when the support block 2105 moves. When the cross plate 2104 moves towards the support block 2105, it will pull the transmission shaft 2115 upward. As a result, the transmission plate 2118 fixed at the bottom of the transmission shaft 2115 will also move upward. Thus, the transmission rope 2103 can be moved through the transmission plate 2118. At this time, the lifting plate 2121, the locking block 2113 and the return spring 2123 can be pulled downward to retract, and then the contents of the encapsulation cover 2106 can be injected. After cooling the water, lift the encapsulation cover 2106 above the encapsulation cylinder 1. Then, align the fixing block 2102 with the notch of the limiting ring 2101 and move it downwards. When the fixing block 2102 moves below the limiting ring 2101, rotate the encapsulation cover 2106 clockwise. At this time, the fixing block 2102 will move along the bottom surface of the limiting ring 2101 until the fixing block 2102 moves to the bottom of the slot 2122. At this time, pull the support block 2105 to reset. Without the support of the support block 2105, the cross plate 2104 will move to its original position under the action of the reset spring 2123, and the locking block 2113 will also be locked inside the slot 2122 under the action of the reset spring 2123.

[0050] Example 2: Please refer to Figure 1 , Figure 2 , Figure 11 , Figure 12 and Figure 13 and Figure 16 The present invention provides a technical solution: an anti-volatile packaging device for isocyanate production. The present invention makes corresponding improvements to the technical problems mentioned in the background art. The packaging mechanism 2 includes an inflatable packaging unit 22, which is disposed on the left side of the packaging cylinder 1. The inflatable packaging unit 22 cooperates with the fastening packaging unit 21. The inflatable packaging unit 22 can perform inflatable sealing treatment on the packaging cylinder 1.

[0051] As a further limitation of the present invention, the inflatable sealing unit 22 includes an inflatable airbag 2207. The outer surface of the inflatable airbag 2207 is fixedly connected to the outer surface of the sealing cylinder 1. The outer surface of the inflatable airbag 2207 is in contact with the outer surface of the sealing cover 2106. A fixing frame 2201 is fixedly connected to the outer surface of the sealing cylinder 1. A fixing cylinder 2204 and an inflatable cylinder 2203 are fixedly connected to the inner wall of the fixing frame 2201. A reciprocating screw 2212 is rotatably connected to the inner wall of the fixing cylinder 2204. A gear 2205 is fixedly connected to the top end of the reciprocating screw 2212. An internal sliding block 2213 is connected, and a lifting block 2209 is fixedly connected to the outer surface of the sliding block 2213. The inner wall of the lifting block 2209 contacts the outer surface of the reciprocating screw 2212, and both sides of the lifting block 2209 contact the inner wall of the fixed cylinder 2204. A long shaft 2211 is fixedly connected to the upper surface of the lifting block 2209, and a piston 2210 is fixedly connected to the top of the long shaft 2211. The outer surface of the piston 2210 is slidably connected to the inside of the air cylinder 2203, and the outer surface of the piston 2210 contacts the inner wall of the air cylinder 2203. An air inlet box 2215 is fixedly connected to the outer surface of the air cylinder 2203. A first mounting pad 2216 is fixedly connected to the inner wall of the air inlet box 2215. A first rubber pad 2214 is fixedly connected to the outer surface of the first mounting pad 2216. A second mounting pad 2217 is fixedly connected to the inner wall of the air cylinder 2203. A second rubber pad 2202 is fixedly connected to the outer surface of the second mounting pad 2217. An air inlet pipe 2206 is fixedly connected to the top of the air cylinder 2203. The right end of the air inlet pipe 2206 passes through the encapsulation cylinder 1 and the inflatable airbag 2207 in sequence and extends into the interior of the inflatable airbag 2207. The outer surface of 206 is fixedly connected to the inner wall of the encapsulation cylinder 1 and the inner wall of the inflatable airbag 2207, respectively. A toothed ring 2208 is fixedly connected to the bottom surface of the encapsulation cover 2106. The outer surface of the toothed ring 2208 meshes with the outer surface of the gear 2205. An inflatable encapsulation unit 22 is provided. The inflatable encapsulation unit 22 can deliver gas to the inside of the inflatable airbag 2207, causing the inflatable airbag 2207 to expand and fill the gap between the encapsulation cover 2106 and the encapsulation cylinder 1. The inflatable encapsulation unit 22 and the fastening encapsulation unit 21 cooperate with each other to provide a good sealing effect for the encapsulation cylinder 1.

[0052] The specific implementation of this embodiment is as follows: Before the encapsulation cover 2106 rotates, it needs to descend vertically a short distance. This short descent allows the gear ring 2208 to engage with the teeth of the gear 2205 from above. As the encapsulation cover 2106 and the gear ring 2208 rotate, the gear ring 2208 drives the gear 2205 to rotate, thereby driving the reciprocating screw 2212 fixed at the bottom of the gear 2205 to rotate. When the reciprocating screw 2212 rotates, it drives the internal sliding block 2213 to move upwards. It is important to understand that... The reciprocating screw 2212 typically consists of two threaded grooves with the same pitch but opposite directions. These two grooves are located on opposite sides of the same screw. When the reciprocating screw 2212 rotates, the side of the threaded groove pushes the sliding block 2213 located within the groove, causing the sliding block 2213 to reciprocate linearly along the screw axis. Due to the design of the threaded grooves, when the sliding block 2213 moves to one end of the screw, it is guided back to the threaded groove at the other end by a transition curve, thus achieving continuous reciprocating motion. The outer surface of the sliding block 2213 is fixed to the lifting block 2209, thereby enabling... The lifting block 2209 pushes the long shaft 2211 and piston 2210 to compress the air inside the air cylinder 2203. When the air inside the air cylinder 2203 is compressed, the compressed air pushes the second rubber pad 2202 upward. At this time, the air inside the air cylinder 2203 enters the air bag 2207 through the air inlet pipe 2206 to inflate the air bag 2207. When the piston 2210 moves downward under the action of the lifting block 2209, the air pressure inside the air cylinder 2203 is lower than the outside air pressure. Therefore, the outside air pushes the first rubber pad 2202 upward. The pad 2214 folds inward and quickly fills the air cylinder 2203. This cycle is repeated to extract outside air and deliver it into the inflatable airbag 2207. It is important to understand that the first mounting pad 2216 and the second mounting pad 2217 are fixed to the air inlet box 2215 and the air cylinder 2203 respectively. Therefore, the first mounting pad 2216 and the second mounting pad 2217 cannot be folded. However, the first rubber pad 2214 and the second rubber pad 2202, which are fixed to the outer surfaces of the first mounting pad 2216 and the second mounting pad 2217, can be folded.

[0053] Example 3: Please refer to Figure 1 , Figure 14 and Figure 15 The present invention provides a technical solution: an anti-volatile packaging device for isocyanate production. The present invention makes corresponding improvements to the technical problems mentioned in the background art. The water sealing mechanism 3 and the packaging mechanism 2 cooperate with each other, and the water sealing mechanism 3 can perform water sealing treatment around the packaging cylinder 1.

[0054] As a further limitation of the present invention, the water sealing mechanism 3 includes two water guide plates 302. The upper surface of each water guide plate 302 is fixedly connected to the bottom surface of the cross plate 2104. Each water guide plate 302 has an inlet 303 and an outlet 304 on its left side. The outer surface of each water guide plate 302 is slidably connected to the inside of the sealing cover 2106. A water storage tank 306 is provided on the upper surface of the sealing cylinder 1. The water storage tank 306 is connected to the outlet 304. An exhaust pipe 307 is fixedly connected to the inner wall of the inflatable airbag 2207. The bottom end of the exhaust pipe 307... A drain pipe 308 is fixedly connected to the inner wall of the encapsulation cylinder 1, extending to the outer side of the encapsulation cylinder 1. The drain pipe 308 is connected to the water storage tank 306. A circular cap 309 is threadedly connected to the outer surface of the exhaust pipe 307 and the outer surface of the drain pipe 308. A water sealing mechanism 3 is provided. The water sealing mechanism 3 can provide a water sealing layer on the outer side of the inflatable airbag 2207. By setting up the fastening encapsulation unit 21, the inflation encapsulation unit 22 and the water sealing mechanism 3, the problem of isocyanate volatilization due to poor sealing during the use of the equipment can be effectively avoided.

[0055] Please see Figure 1 and Figure 4 The upper surface of the encapsulation cover 2106 is fixedly connected to the water injection pipe 305. The outer surface of the water injection pipe 305 is threadedly connected to the threaded cover 301. By setting the threaded cover 301, the water injection pipe 305 can be encapsulated to prevent the internal cold water from splashing out.

[0056] The specific implementation of this embodiment is as follows: When it is necessary to inject cool water into the interior of the sealing cover 2106, the water injection pipe 305 can be opened for injection. At this time, the sealing cover 2106 is not fully installed, so the cross plate 2104 is still positioned above the support block 2105 under the action of the support block 2105. The two water guide plates 302 fixed to the bottom surface of the cross plate 2104 are also completely inside the sealing cover 2106. Furthermore, the water outlet 304 opened on the left side of the water guide plate 302 is blocked by the inner wall of the sealing cover 2106. Therefore, the water inside the sealing cover 2106 cannot flow into the water storage tank 306 through the water guide plate 302. When the locking block 2113 is engaged with the slot 2122, the cross plate 2104 will also move downwards. The movement of the cover 2106 signifies that the sealing is complete. As the cross plate 2104 moves downward, it pushes the two water guide plates 302 fixed on the bottom surface downward until the outlet 304 on the left side of the water guide plate 302 is no longer blocked by the inner wall of the cover 2106. At this point, the cool water inside the cover 2106 will enter the inlet 303, and then enter the water storage tank 306 through the inner cavity of the water guide plate 302 and the outlet 304, thus completing the water seal. In addition, when it is necessary to open the device, the two circular caps 309 threaded on the outer surface of the drain pipe 308 and the exhaust pipe 307 are rotated respectively to discharge the gas inside the inflatable airbag 2207 and the cool water inside the water storage tank 306.
