Description

Technical Field

[0001] The utility model relates to the technical field of nylon production, in particular to a temperature control mechanism and a polymerization kettle for producing long carbon chain nylon. Background Art

[0002] Long carbon chain nylon refers to a polyamide polymer with a longer carbon chain in the molecular chain. Compared with conventional nylon (such as nylon 6, nylon 66, etc.), it has more carbon atoms on its main chain.

[0003] At present, a Chinese utility model with publication number CN213222102U discloses a temperature control system for an environmentally friendly polymerization kettle for nylon resin production. The device uses a temperature control box to adjust the temperature of the inner cavity, and heat exchange is performed through a circulation pipe with condensed water. The temperature control box is connected to the inner cavity through a first connecting pipe and a second connecting pipe, thereby achieving efficient heat exchange and realizing the temperature control of the polymerization kettle.

[0004] However, since the circulation pipe lacks its own cooling means, when the temperature change span and the number of large adjustments are large, the condensed water may have a high temperature and it is difficult to achieve a good temperature adjustment effect. Therefore, the utility model proposes a temperature control mechanism and a polymerization kettle for long carbon chain nylon production to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a temperature control mechanism and a polymerization kettle for producing long-chain nylon, so as to solve the problem raised in the above-mentioned background technology that when the temperature difference is large and the number of temperature adjustments is large, the circulation pipe will lack its own cooling means, resulting in the condensed water having a high temperature itself and being difficult to achieve a good temperature adjustment effect.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solution: a temperature control mechanism, the temperature control mechanism comprising:

[0007] A circulation pipe, one side of the circulation pipe is fixedly connected with an outlet pipe, one end of the outlet pipe is fixedly connected with a cooling pipe arranged in a "spiral shape", one end of the cooling pipe is fixedly connected with a transfer box, one side of the transfer box is fixedly connected with a support plate, one side of the support plate is fixedly connected with a plurality of cooling fans distributed in a linear array, the positions of the cooling fans correspond to the cooling pipe, one end of the transfer box is fixedly connected with an output pipe, one end of the output pipe is fixedly connected with a No. 1 suction pump, and the No. 1 suction pump and the circulation pipe are plugged and fixed.

[0008] Preferably, the support plate is arranged in an "L" shape, and the lowest end of the outlet pipe is lower than the lowest end of the circulation pipe.

[0009] Preferably, a temperature sensor No. 1 is fixedly connected to one side of the transfer box, a solenoid valve is fixedly connected to one end of the transfer box, a flow guide tube No. 1 is fixedly connected to one end of the solenoid valve, and a cooling box is fixedly connected to one end of the flow guide tube No. 1.

[0010] Preferably, a No. 2 temperature sensor is fixedly connected to one side of the cooling box, a No. 2 flow guide pipe is fixedly connected to one end of the cooling box, and a No. 2 flow guide pipe is fixedly connected to one side of the No. 2 flow guide pipe.

[0011] Preferably, one end of the water storage tank is fixedly connected to a connecting pipe, one end of the connecting pipe is fixedly connected to a No. 2 suction pump, and the No. 2 suction pump and the circulation pipe are plugged and fixed.

[0012] A polymerization kettle for producing long carbon chain nylon comprises the above-mentioned temperature control mechanism.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The device transfers the condensed water with higher temperature in the circulation pipe into the cooling pipe through the outlet pipe. The condensed water can be cooled in the process of being transmitted into the transfer box through the cooling pipe through multiple cooling fans. The cooling pipe is arranged in a "spiral shape" to increase the reaction path of the condensed water in a limited space, thereby improving the cooling effect of the condensed water. The cooled condensed water in the transfer box will be extracted by the No. 1 suction pump through the outlet pipe and input into the circulation pipe, thereby completing the circulation cooling of the condensed water and ensuring that the condensed water temperature is always low. This also solves the problem that when the temperature difference is large and the number of temperature adjustments is large, the circulation pipe will lack its own cooling means, resulting in the condensed water having a high temperature and being difficult to achieve a good temperature adjustment effect.

[0022] See also Figure 1 to Figure 2 , the utility model provides a technical solution:

[0023] Embodiment 1, a temperature control mechanism, the temperature control mechanism comprises: a circulation pipe 1.

[0024] Specifically, one side of the circulation pipe 1 is fixedly connected with an outlet pipe 2, one end of the outlet pipe 2 is fixedly connected with a cooling pipe 3 arranged in a "spiral shape", one end of the cooling pipe 3 is fixedly connected with a transfer box 4, one side of the transfer box 4 is fixedly connected with a support plate 8, one side of the support plate 8 is fixedly connected with a plurality of cooling fans 9 distributed in a linear array, the position of the cooling fan 9 corresponds to the cooling pipe 3, one end of the transfer box 4 is fixedly connected with an output pipe 5, one end of the output pipe 5 is fixedly connected with a No. 1 suction pump 6, the No. 1 suction pump 6 and the circulation pipe 1 are plugged and fixed. In actual implementation, the circulation pipe 1 is fixedly connected with a plurality of cooling fans 9 distributed in a linear array. The cooling fans 9 are located at positions corresponding to the cooling pipe 3. The condensed water with a higher temperature will first flow into the outlet pipe 2, and then flow into the cooling pipe 3 from the outlet pipe 2. The condensed water will flow into the transfer box 4 after being cooled by multiple cooling fans 9 in the cooling pipe 3 which is arranged in a "spiral shape", and then be extracted from the transfer box 4 through the output pipe 5 by the No. 1 suction pump 6, and then be input into the circulation pipe 1 by the No. 1 suction pump 6, so as to cool the condensed water in the circulation pipe 1. The "spiral" cooling pipe 3 can increase the flow path of the condensed water in the cooling pipe 3, thereby increasing the time for the condensed water to be cooled by the cooling fan 9, thereby improving the cooling effect.

[0025] In order to better install the cooling fan 9, the support plate 8 of the present application is set to an "L" shape, which can provide the cooling fan 9 with working space. The lowest end of the outlet pipe 2 is lower than the lowest end of the circulation pipe 1, which can avoid the backflow of condensed water.

[0026] In order to further increase the cooling path, a temperature sensor No. 1 is fixedly connected to one side of the transfer box 4 of the present application, a solenoid valve 10 is fixedly connected to one end of the transfer box 4, one end of the solenoid valve 10 is fixedly connected to a flow guide pipe No. 11, and one end of the flow guide pipe No. 11 is fixedly connected to a cooling box 12. When the temperature monitored by the temperature sensor No. 1 7 is still high, the solenoid valve 10 will open to allow the condensed water to flow into the cooling box 12 through the flow guide pipe No. 11, and then cool down naturally.

[0027] In order to improve the function of the cooling box 12, a No. 2 temperature sensor 13 is fixedly connected to one side of the cooling box 12 of the present application, a No. 2 flow guide pipe 14 is fixedly connected to one end of the cooling box 12, and a No. 2 flow guide pipe 14 is fixedly connected to one side of the No. 2 flow guide pipe 14. After the condensed water in the cooling box 12 is detected by the No. 2 temperature sensor 13 to meet the temperature drop standard, the water in the cooling box 12 will be transferred to the water storage tank 15 through the No. 2 flow guide pipe 14 and stored, thereby increasing the function of the cooling box 12.

[0028] In order to further improve the utilization of condensed water, one end of the water tank 15 of the present application is fixedly connected to a connecting pipe 16, and one end of the connecting pipe 16 is fixedly connected to a No. 2 suction pump 17. The No. 2 suction pump 17 and the circulating pipe 1 are plugged and fixed. When the condensed water that meets the standards stored in the water tank 15 is input to the cooling box 12 by the transfer box 4 and the condensed water that does not meet the cooling standards is pumped out from the water tank 15 by the No. 2 suction pump 17 through the connecting pipe 16 to ensure the water storage capacity in the circulating pipe 1.

[0029] The present application also discloses a polymerization kettle for producing long carbon chain nylon, comprising the above-mentioned temperature control mechanism.
