Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of carbon fiber production, specifically a cleaning device for high-strength and high-modulus carbon fiber spinning solution degassing equipment, which can significantly shorten the equipment cleaning time, reduce cleaning dead corners and the amount of dimethyl sulfoxide cleaning solution used, and improve the cleaning efficiency. Background Art
[0002] During the production of high-strength and high-modulus carbon fibers, the spinning solution needs to be degassed. Under vacuum conditions, a large amount of gel-like spinning solution and impurities will adhere to the inner wall of the degassed equipment. The attached gel-like spinning solution and impurities will have a significant impact on the degassed effect, reducing the degassed effect, increasing production costs, and causing waste of raw materials. Therefore, the spinning solution degassed equipment needs to be cleaned regularly. The traditional cleaning method is to fill the degassed equipment with dimethyl sulfoxide and use dimethyl sulfoxide solution for soaking or self-circulating cleaning to dissolve the gel-like spinning solution and impurities. This cleaning method is time-consuming and there are dead corners in the equipment. It is difficult to completely clean the dead corners. In addition, this method requires the use of a large amount of dimethyl sulfoxide, which is very costly to clean. Summary of the Invention
[0003] Aiming at the current problem that the degassing equipment for spinning solution of high-strength and high-modulus carbon fibers is difficult and time-consuming to clean, the utility model proposes a cleaning device for degassing equipment of high-strength and high-modulus carbon fibers, which can shorten the cleaning time, reduce cleaning dead corners, and improve the cleaning efficiency of the degassing equipment.
[0004] The utility model is achieved through the following measures:
[0005] A cleaning device for high-strength and high-modulus carbon fiber spinning solution degassing equipment is provided with a cleaning tank for storing cleaning solution, and is characterized in that a liquid outlet and a liquid inlet are provided on the cleaning tank, the liquid outlet is connected to the liquid inlet end of a heat exchanger via a pipeline, a high-pressure cleaning pump and a regulating valve are provided on the pipeline between the liquid outlet and the heat exchanger, the liquid outlet end of the heat exchanger is connected to a three-dimensional cleaning nozzle, the three-dimensional cleaning nozzle is arranged at the liquid inlet of the degassing equipment, and the liquid inlet of the cleaning tank is connected to the liquid discharge port of the degassing equipment via a pipeline.
[0006] The utility model provides a thermometer on the liquid outlet pipe of the heat exchanger for displaying the liquid temperature at the liquid outlet. When in use, it is used to monitor the liquid temperature at the liquid outlet and control it at 40°C-60°C. Properly increasing the temperature of dimethyl sulfoxide will increase the dissolution rate of the spinning solution and speed up the cleaning process.
[0007] A pressure gauge is also provided on the pipeline between the liquid outlet of the heat exchanger and the three-dimensional cleaning nozzle in the utility model, for detecting the pressure of the cleaning solution fed into the three-dimensional cleaning nozzle.
[0008] The three-dimensional cleaning nozzle of the utility model is installed in the degassing equipment to be cleaned through a fixing component. The fixing component adopts a tongue and groove flange, which has good sealing performance and can effectively prevent the leakage of dimethyl sulfoxide. Furthermore, three three-dimensional cleaning nozzles are preferably provided, wherein the three three-dimensional cleaning nozzles are distributed at equal distances, and the three-dimensional cleaning nozzle located in the center extends into the degassing equipment to be cleaned to a depth greater than the insertion depth of the three-dimensional cleaning nozzles on both sides, so as to minimize cleaning dead angles.
[0009] When the utility model is working, dimethyl sulfoxide solution is stored in the cleaning tank, and the dimethyl sulfoxide solution is pumped into the degassing equipment through the high-pressure cleaning pump through the heat exchanger and the three-dimensional cleaning nozzle, and then flows back to the cleaning tank to form a cleaning circulation system; since there are regulating valves and pressure gauges between the high-pressure cleaning pump and the three-dimensional cleaning nozzle, the pressure of the three-dimensional cleaning nozzle is adjusted by adjusting the opening of the regulating valve at the outlet of the high-pressure cleaning pump to ensure that the three-dimensional cleaning nozzle is in a high-pressure operating state. Multiple three-dimensional cleaning nozzles work simultaneously to achieve the effect of reducing blind spots in equipment cleaning. A thermometer is provided at the outlet of the heat exchanger, and the dimethyl sulfoxide solution is heated by the heat exchanger to maintain a certain temperature of the dimethyl sulfoxide solution to achieve the best cleaning effect.

[0011] Attachment Figure 1 It is a structural diagram of the present utility model.
[0012] Reference numerals: degassing equipment to be cleaned 1, three-dimensional cleaning nozzle 2, cleaning tank 3, high-pressure cleaning pump 4, heat exchanger 5, regulating valve 6, pressure gauge 7, dimethyl sulfoxide solution 8, temperature q meter 9. DETAILED DESCRIPTION
[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0014] Example 1:
[0015] As attached Figure 1 As shown, this example provides a spinning solution degassing equipment cleaning device that reduces cleaning dead angles and improves cleaning efficiency by adding three three-dimensional cleaning nozzles and temperature control components in the degassing equipment. The device includes a cleaning tank 3 for storing dimethyl sulfoxide solution 8, a high-pressure cleaning pump 4, a heat exchanger 5 and a three-dimensional cleaning nozzle 2 connected in sequence by pipelines. When working, the dimethyl sulfoxide solution is pumped into the degassing equipment 1 through the high-pressure cleaning pump 4 through the heat exchanger 5 and the three-dimensional cleaning nozzle 2, and then flows back to the cleaning tank to form a cleaning circulation system.
[0016] In this example, there are regulating valves 6 and pressure gauges 7 between the high-pressure cleaning pump 4 and the three-dimensional cleaning nozzles 2. By adjusting the opening of the regulating valve 6 at the outlet of the high-pressure cleaning pump 4, the pressure of the three-dimensional cleaning nozzles 2 can be adjusted to ensure that the three-dimensional cleaning nozzles 2 are in a high-pressure operating state. The three three-dimensional cleaning nozzles 2 are distributed at equal distances, and the three-dimensional cleaning nozzles located in the center extend deeper into the degassing equipment to be cleaned than the three-dimensional cleaning nozzles on both sides. The three three-dimensional cleaning nozzles 2 work simultaneously to achieve the effect of reducing blind spots in equipment cleaning.
[0017] In this example, a thermometer 9 is located at the outlet of the heat exchanger. Dimethyl sulfoxide solution 8 is heated by heat exchanger 5 to maintain a constant temperature for optimal cleaning results. Heat exchanger 5 is supplied with 12°C cold water and 65°C hot water. The temperature is automatically adjusted by monitoring the real-time temperature of thermometer 9, maintaining a constant temperature range of 40°C to 60°C.
[0018] Compared with the prior art, the utility model has the remarkable advantages of reasonable structure, short cleaning time and high cleaning efficiency.
