Technical Field

[0001] This utility model relates to the field of thermostatic pressure equipment, and in particular to a thermostatic pressure medium heating device. Background Technology

[0002] Thermostatic pressing (WSP) technology densifies materials by applying high temperature and high pressure. It is widely used in the molding and processing of materials such as ceramics and metal powders. The heating method of the medium in existing WSP equipment is one of the key factors affecting its working efficiency and applicable pressure range, which directly relates to the quality of material processing and the operational stability of the equipment.

[0003] In terms of medium heating, existing warm isostatic pressing equipment typically heats the medium supplied to the booster through a flow channel. This method is widely used in warm isostatic pressing equipment with a pressure range of 100-200 MPa, and can basically meet the temperature requirements of the medium in this pressure range, ensuring the normal operation of the equipment.

[0004] However, as industrial production demands increasingly higher material performance, the outer flow channel in high-pressure isostatic pressing equipment needs to withstand extremely high pressure. This requirement is difficult to meet in terms of technical implementation and processing technology, making it unsuitable for ultra-high pressure conditions. In addition, the pipe interfaces of existing equipment mostly adopt traditional connection methods, which are prone to deterioration of sealing performance and loosening of connections under the dual effects of ultra-high pressure and temperature changes, thereby affecting the stability and safety of media transportation. Utility Model Content

[0008] As a further description of the above technical solution:

An upper clamp abuts against the top of the outer side of the washer and a lower clamp abuts against the bottom of the outer side of the washer. Mounting blocks are fixedly connected to the left and right sides of the upper clamp and the lower clamp, and bolts are installed on the outside of the mounting blocks.

[0023] 1. In this utility model, by setting up a heat exchange oil tank and multiple sets of internal coils, the heating method of setting up flow channels on the outside of the high-pressure chamber in the existing technology is changed. It can adapt to the ultra-high pressure conditions of 300-600 MPa, and solves the problem that the outer flow channel is difficult to implement in terms of technology and process due to the need to bear excessive pressure.

[0033] Reference Figures 1-5This utility model provides an embodiment of a thermostatic isostatic medium heating device, including a heat exchange oil tank 1. The heat exchange oil tank 1 is the core heat exchange area of ​​the entire device, providing a closed space for heating the internal medium. A circulation pipe 3 is fixedly connected to the left side of the heat exchange oil tank 1, and a circulation pipe 4 is fixedly connected to the right side of the heat exchange oil tank 1. Circulation pipe 3 and circulation pipe 4 are channels for the circulation of the heating medium, and they cooperate to form a medium circulation loop, responsible for sending the medium heated by the mold temperature controller 2 into the heat exchange oil tank 1. The other end of the circulation pipe 4 is fixedly connected to the mold temperature controller 2. The temperature controller 2 provides a heat source for the entire unit, capable of heating or cooling the medium to maintain the required process temperature. The heat exchange oil tank 1 contains multiple evenly distributed coils 6, which hold the medium to be heated supplied by the booster 11. Heating is achieved through heat exchange with the heating medium in the heat exchange oil tank 1. An output pipe 7 is fixedly connected to the rear end of each coil 6, serving as a channel to transport the heated medium from the coil 6 to the connecting pipe 12. A locking block 8 is fixedly connected to the front end of the output pipe 7, and a locking assembly is also fixedly connected to the front end of the output pipe 7. The locking assembly is used to secure the medium. The tight connection between the output pipe 7 and the connecting pipe 12 ensures the sealing and stability of the connection. The connecting pipe 12 is fixedly connected to the other side of the locking assembly. The connecting pipe 12 receives the medium transported by the output pipe 7 and ultimately delivers it to the ultra-high pressure chamber 14. A locking block 13 is fixedly connected to the front end of the outer side of the connecting pipe 12, and the ultra-high pressure chamber 14 is fixedly connected to the other end of the connecting pipe 12. The ultra-high pressure chamber 14 is the location for isostatic pressure treatment of the medium and can withstand ultra-high pressures of 300-600 MPa. An input pipe 5 is fixedly connected to the front end of the coil 6. The input pipe 5 is used to... The pressurized medium from the booster 11 is delivered to the channel of the coil 6. The booster 11 is fixedly connected to the front end of the input pipe 5. The booster 11 can pressurize the medium at normal temperature and pressure to 300-600 MPa to meet the requirements of ultra-high pressure conditions. A temperature sensor 9 is installed on the rear side of the heat exchange oil tank 1. The temperature sensor 9 can monitor the temperature of the medium in the heat exchange oil tank 1 in real time, providing a basis for the temperature regulation of the mold temperature controller 2. A pressure sensor 10 is installed on the rear side of the heat exchange oil tank 1. The pressure sensor 10 is used to detect the pressure value in the heat exchange oil tank 1 in real time to ensure that the device operates within a safe pressure range.

[0034] Reference Figure 4 and Figure 5The locking assembly includes a washer 20, which is slidably connected to the front end of the output pipe 7 and the other end of the washer 20 is slidably connected to the front end of the connecting pipe 12. The washer 20 is made of elastic material and can fill the gap between the output pipe 7 and the connecting pipe 12 to enhance the sealing of the connection. The top of the outer side of the washer 20 abuts against an upper clamp 15, and the bottom of the outer side of the washer 20 abuts against a lower clamp 16. The upper clamp 15 and the lower clamp 16 cooperate to apply pressure to the washer 20 from the outside to enhance its sealing performance. Mounting blocks 17 are fixedly connected to the left and right sides of the upper clamp 15 and the lower clamp 16. The mounting blocks 17 provide positions for the installation of bolts 19 and facilitate the fixing of the upper clamp 15 and the lower clamp 16. Bolts 19 are installed on the outside of the mounting blocks 17. Mounting holes 18 are opened on the outside of the mounting blocks 17. The bolts 19 are slidably connected in the mounting holes 18. The upper clamp 15 and the lower clamp 16 are tightly connected together to ensure stable pressure on the gasket 20. The gasket 20 has connecting grooves 21 on both the front and rear sides. The front end of the output pipe 7 is slidably connected in the connecting groove 21, and the front end of the connecting pipe 12 is slidably connected in the connecting groove 21. The shape of the connecting groove 21 matches the front end of the output pipe 7 and the connecting pipe 12, which can enhance the fit between the gasket 20 and the pipe. The first clamp 8 abuts against the front side of the gasket 20, the second clamp 13 abuts against the rear side of the gasket 20, and the bottom side of the upper clamp 15 abuts against the top side of the lower clamp 16. The two form a complete ring structure, which is evenly wrapped around the outside of the gasket 20. The upper clamp 15 and the lower clamp 16 are fitted on the outside of the first clamp 8, and the upper clamp 15 and the lower clamp 16 are fitted on the outside of the second clamp 13. In this way, the fixation of the connection between the connecting pipe 12 and the gasket 20 is strengthened.

[0035] Working principle: First, the mold temperature controller 2 is started to heat the medium. The heated medium enters the heat exchange oil tank 1 through the second circulation pipe 4 and exchanges heat with the internal coil 6. Then, it flows back to the mold temperature controller 2 through the first circulation pipe 3, forming a stable heating cycle. The booster 11 pressurizes the normal temperature and pressure medium to 300-600 MPa and injects it into the coil 6 through the input pipe 5. The high-pressure medium in the coil 6 absorbs heat and rises in temperature in the heat exchange oil tank 1. Then, it is transported to the ultra-high pressure chamber 14 through the output pipe 7 and the connecting pipe 12. During this process, the temperature sensor 9 monitors the temperature of the medium in the heat exchange oil tank 1 in real time and feeds it back to the mold temperature controller 2 for temperature adjustment. The pressure sensor 10 detects the pressure in real time to ensure the safe operation of the system.

[0036] In addition, regarding the pipe connection, the output pipe 7 and the connecting pipe 12 are tightly connected by a locking assembly. The connecting groove 21 of the gasket 20 mates with the front ends of the two pipes respectively, filling the gap and enhancing the seal. The first clamp 8 and the second clamp 13 abut against the gasket 20 from both sides for limiting the position. The upper clamp 15 and the lower clamp 16 wrap around the outside of the gasket 20 and the clamps, and are tightened by the bolts 19 in the mounting block 17 and the mounting hole 18 to form a stable pressure, ensuring the sealing and structural stability of the connection when transporting ultra-high pressure media.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
