Detailed Embodiments
[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. The described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0022] Reference Figures 1 - 4 , a resin synthesis condensation recovery device, comprising a reaction kettle 1 and a frame 7. A condenser 6 is fixedly installed in the frame 7 by bolts. A U-shaped pipe 2 is welded to the top of the reaction kettle 1, and the U-shaped pipe 2 is communicated with the condenser 6. A reflux pipe 3 is fixedly installed at the bottom of the condenser 6 by bolts, and one end of the reflux pipe 3 is wound above the condenser 6 and communicated with the condenser 6. A water tank 9 is fixedly installed in the frame 7 by bolts, and the other end of the reflux pipe 3 is communicated with the water tank 9. A water pump 11 is fixedly installed in the frame 7 by bolts. One end of the water inlet of the water pump 11 is fixedly installed with a first connecting pipe 10 communicated with the water tank 9, and one end of the water outlet of the water pump 11 is fixedly installed with a second connecting pipe 13 communicated with the reaction kettle 1. The high-temperature gas in the reaction kettle 1 will enter the condenser 6 through the U-shaped pipe 2. The condenser 6 condenses the high-temperature gas into a liquid state, and then flows into the reflux pipe 3. When the flowing liquid passes through the connection between the reflux pipe 3 and the water tank 9, it will flow into the water tank 9 and accumulate in the water tank 9. Then, the water pump 11 is used to extract the liquid in the water tank 9 through the first connecting pipe 10 and transport the liquid to the reaction kettle 1 through the second connecting pipe 13 for reaction, so as to condense and recover the high-temperature gas, avoid the loss of volatile raw materials in the high-temperature gas, and save costs.
[0023] In the present utility model, a blocking block 16 is welded in the reflux pipe 3. The blocking block 16 is located at the connection between the reflux pipe 3 and the water tank 9. There is a gap between the top of the blocking block 16 and the reflux pipe 3. The blocking block 16 will block the liquid to prevent the liquid from flowing through the connection between the reflux pipe 3 and the water tank 9. At the same time, since there is a gap between the top of the blocking block 16 and the reflux pipe 3, the uncondensed high-temperature gas entering the reflux pipe 3 will flow back to the condenser 6 through the reflux pipe 3 for re-condensation. A support frame 15 is fixedly installed at the position directly above the reaction kettle 1 in the U-shaped pipe 2 by bolts. An electric fan 14 is fixedly installed at the top of the support frame 15 by bolts. When the electric fan 14 is started, the electric fan 14 will extract the high-temperature gas generated in the reaction kettle 1 and divert the high-temperature gas to facilitate the high-temperature gas to flow into the condenser 6 through the U-shaped pipe 2. A liquid level gauge 8 is provided on one side of the water tank 9 to measure the liquid level in the water tank 9, which is convenient for the staff to observe the liquid level in the water tank 9. A coolant inlet pipe 5 is provided at the top of the condenser 6, and a coolant outlet pipe 4 is provided at the bottom of the condenser 6.
[0024] Working principle: When in use, the high-temperature gas in the reactor 1 will enter the condenser 6 through the U-shaped tube 2. At the same time, the electric fan 14 is started. The electric fan 14 will extract the high-temperature gas generated in the reactor 1 and divert the high-temperature gas to facilitate the flow of the high-temperature gas through the U-shaped tube 2 into the condenser 6. The condenser 6 condenses the high-temperature gas into a liquid state, and then it flows into the return pipe 3. When the flowing liquid passes through the connection between the return pipe 3 and the water tank 9, it will flow into the water tank 9 and accumulate in the water tank 9. At the same time, the blocking block 16 will block the liquid to prevent the liquid from flowing past the connection between the return pipe 3 and the water tank 9. At the same time, since there is a gap between the top of the blocking block 16 and the return pipe 3, the uncondensed high-temperature gas that enters the return pipe 3 will flow back to the condenser 6 through the return pipe 3 for re-condensation. Then, the water pump 11 extracts the liquid in the water tank 9 through the first connecting pipe 10 and transports the liquid to the reactor 1 through the second connecting pipe 13 for reaction, thereby condensing and recovering the high-temperature gas, avoiding the loss of volatile raw materials in the high-temperature gas, and saving costs.
