Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary devices for composite material processing equipment, and more specifically, to a room temperature eddy current temperature control mold temperature controller. Background Art

[0002] Composite materials are a new type of material composed of reinforcing materials and resins. During the production process, the resin needs to be heated according to its characteristics and the temperature needs to be limited to a specific temperature range. The temperature required for the production of some resins is only 30-40°C.

[0003] In the production process of composite material dipping process, the resin is heated by placing the resin in the dipping tank (load), and heating the spacer with hot water / hot oil. The hot water / hot oil is heated by the mold temperature controller and then transported to the dipping tank (load) spacer through pipelines under pump pressure to heat the resin.

[0004] The mold temperature controller mainly provides hot water / hot oil through closed-loop control between the temperature sensor and the heater. However, in the actual use of the mold temperature controller, the high-speed rotating pump (commonly used: multi-stage vane pump, pressure: above 0.3MPa) produces high-speed friction on the fluid (hot water / hot oil) during the transportation process. The fluid and the blades will generate heat during the friction process. This heating process is not controlled by the heater and temperature sensor. In actual use, the heat generated by the pump will increase the temperature of the fluid by 15-20℃.

[0005] In the production process of a specific resin (e.g. the required temperature for production is 35°C), the ambient temperature is affected by seasonal changes. In summer, the ambient temperature is 30°C. At this time, the mold temperature controller needs to provide 35°C hot water / hot oil. However, due to the heat generated by the pump itself, the hot water / hot oil temperature provided is 50-55°C, which is far higher than the required temperature.

[0006] Among the existing mold temperature controllers, there are mold temperature controllers equipped with heat exchangers. Such mold temperature controllers need to be supplied with cooling water for cooling or dissipate heat through a blower-type radiator. This method of supplying cooling water requires an ice machine or a condensation tower to provide circulating water; the blower-type radiator can only provide limited cooling and cannot reduce the oil temperature to room temperature + 1 to 10°C. Both of the above cooling methods have limitations.

[0007] Therefore, there is a need for a room temperature eddy current temperature control mold temperature controller that can accurately control the temperature of the mold temperature controller without providing a chiller or a condensing tower. Utility Model Content

[0010] Furthermore, the cold source supply end includes a first inlet and a first outlet, the first inlet is connected to the vortex tube through a pipeline, the vortex tube is connected to compressed air, and the first outlet is connected to the atmosphere.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] like Figure 1 As shown, the utility model provides a room temperature type vortex temperature control mold temperature controller, comprising: an oil tank 1, the oil tank 1 is connected to the glue tank 6 through a pipeline 5, a tee 11 is provided on the pipeline 5, one end of the tee 11 is connected to the glue tank 6, and the outlet of the glue tank 6 is connected to the oil tank 1 through the pipeline 5, and the other end of the tee 11 is connected to a heat exchanger 8, the heat exchanger 8 includes a cold source supply end and an end to be cooled, the cold source supply end is connected to a vortex tube 9 for circulating a cooling medium, and the end to be cooled is connected to the oil tank 1 for circulating the medium to be cooled.

[0023] The oil tank 1 is filled with a heat transfer medium, which may be water, heat transfer oil, etc. The oil tank 1 is connected to the oil pump 2 through the pipeline 5, and the oil pump 2 is connected to the heater 3 through the pipeline 5. The outlet of the heater 3 is connected to a tee 11, one end of the tee 11 is connected to the inlet of the rubber tank 6 through the pipeline 5, and a temperature sensor 4 is installed at the outlet of the tee 11, and the outlet of the rubber tank 6 is connected to the oil tank 1 through the pipeline 5. A manual valve, a filter and a pressure gauge are provided in this circuit. The manual valve is used to close the pipeline 5 during equipment maintenance and inspection, the filter is used to filter impurities in the pipeline 5 to prevent contamination of the oil temperature machine, and the pressure gauge is used to display the pressure of the pipeline 5 and monitor whether the oil pump 2 is operating normally.

[0024] The other end of the tee 11 is connected to the first solenoid valve 12 through the pipeline 5. In this embodiment, the first solenoid valve 12 is a solenoid valve for controlling liquid. The first solenoid valve 12 is connected to the heat exchanger 8 through the pipeline 5, and the heat exchanger 8 is connected to the oil tank 1 through the pipeline 5.

[0025] The two ends of the heat exchanger 8 are respectively a cold source supply end and an end to be cooled. The end to be cooled is connected to the mold temperature controller pipeline 5 for circulating the medium to be cooled. The end to be cooled includes a second inlet and a second outlet. The first solenoid valve 12 is connected to the second inlet through the pipeline 5, and the second outlet is connected to the oil tank 1 through the pipeline 5.

[0026] The cold source supply end is used to circulate the cooling medium. The cold source supply end includes a first inlet and a first outlet. The first inlet is connected to a vortex tube 9. The air inlet of the vortex tube 9 is connected to compressed air 10. The device needs to provide compressed air 10. The compressed air 10 is connected to the filter pressure reducing valve through a pipeline 5, and then connected to the second solenoid valve 7 through the pipeline 5. The second solenoid valve 7 is a solenoid valve for controlling the gas. The second solenoid valve 7 is connected to the vortex tube 9 through a pipeline 5 to supply compressed air 10 to the air inlet of the vortex tube 9. The hot air outlet of the vortex tube 9 is connected to the air, and the cold air outlet of the vortex tube 9 is connected to the first inlet of the cold source supply end on the heat exchanger 8 through the pipeline 5, and the first outlet is connected to the atmosphere.

[0027] The principle of the vortex tube 9 is to flow to one side in a high-speed rotating manner. During the movement of this airflow, the air in the outer layer will heat up, and on the contrary, the air in the inner layer will cool down. When it moves to one end, the cold air will flow back along the center of the vortex to form a cooling source.

[0028] The control system of the device can receive the signal of the temperature sensor 4, so as to control the heating of the heater 3, the operation of the oil pump 2, and the on and off of the first solenoid valve 12 and the second solenoid valve 7.

[0029] Working principle of this device:

[0030] The control system controls the oil pump 2 to extract the heat transfer medium from the oil tank 1 and heats the heat transfer medium through the heater 3 .

[0031] Process 1:

[0032] When the temperature value detected by the temperature sensor 4 is lower than the set temperature value, the heater 3 starts heating to heat the heat transfer medium until the temperature detected by the temperature sensor 4 is the same as or close to the set temperature value. Driven by the oil pump 2, the heat transfer medium completes a heating cycle through the loop of oil tank 1-oil pump 2-heater 3-tee 11-pipeline 5-rubber groove 6-pipeline 5-oil tank 1. At this time, the first solenoid valve 12 is in a closed state.

[0033] Process 2:

[0034] When the temperature value detected by the temperature sensor 4 is higher than the set temperature value, the heater 3 turns off the heating function, and the first solenoid valve 12 and the second solenoid valve 7 are started synchronously. At this time, the heat transfer medium is divided into two flows at the position of the three-way 11 under the drive of the oil pump 2. Because the "three-way 11-first solenoid valve 12-heat exchanger 8-oil tank 1" circuit is located inside the oil temperature machine and the pipe 5 is shorter than the "three-way 11-pipeline 5-rubber groove 6-pipeline 5-oil tank 1" circuit, the "three-way 11-first solenoid valve 12-heat exchanger 8-oil tank 1" circuit has a lower internal resistance than the "three-way 11-pipeline 5-rubber groove 6-pipeline 5-oil tank 1" circuit, so most of the heat transfer medium passes through the "three-way 11-first solenoid valve 12- The heat exchanger 8-oil tank 1" loop circulates. At this time, the second solenoid valve 7 is opened, and the compressed air 10 passes through the "filter pressure reducing valve-pipeline 5-second solenoid valve 7-pipeline 5-vortex tube 9" at a high speed. Under the blowing of the high-speed compressed air 10, the cold air outlet of the vortex tube 9 releases cold air, and the cold air outlet of the vortex tube 9 is connected with the first inlet of the cold source supply end of the heat exchanger 8 through the pipeline 5. At this time, the cold air output by the vortex tube 9 exchanges heat in the heat exchanger 8, and the heat of the heat-conducting medium with a higher temperature is transferred, so that the temperature of the heat-conducting medium is reduced; the first outlet of the cold source supply end is connected to the atmosphere, and can discharge the cold air after the heat exchange. This process is the cooling process of the heat-conducting medium.

[0035] The cooled heat transfer medium flows back to the oil tank 1, and then the temperature of the heat transfer medium in the oil tank 1 is neutralized to reduce the temperature of the heat transfer medium in the oil tank 1 to a state below the set value. At this time, the recirculated heat transfer medium can repeat process 1.

[0036] The lowest temperature of cold air released from the cold air outlet of the vortex tube 9 used in the present device is -46°C, which meets the temperature requirement of cooling the heat transfer medium to room temperature. In addition, the vortex tube 9 in the present device is small in size and occupies less space for the entire device.

[0037] The device only needs to provide power and compressed air 10, and no additional cold source supply is required.
