[0002] During the operation of high-temperature and high-pressure equipment such as autoclaves, the inner wall of the equipment, the internal product or the height difference will inevitably cause a temperature difference inside. Due to the temperature difference, condensed water will continue to precipitate. If the condensed water cannot be discharged from the outside of the system in time, it will accumulate at the bottom of the autoclave and other equipment, which will not only reduce the curing temperature, but also require continuous supply of excess energy to the autoclave and other equipment to maintain the high temperature, increasing the production cost of the finished product. If the heat preservation cannot be carried out in time, it will also affect the quality of the product (reducing the strength of the product, causing cracks in the product during the curing process, etc.), and at the same time, it will cause excessive tensile stress on the internal surface of the autoclave and other equipment, making it very likely that stress cracks and other defects will occur at the bottom of the autoclave, thereby reducing the service life of the autoclave and is very likely to cause a safety accident (autoclave cracking and explosion).

[0038] Embodiment: This embodiment aims to provide an automatic release device for high-temperature and high-pressure steam condensate, the main function of which is to replace the manual automatic discharge of condensate inside the autoclave, saving time and effort, and thus avoiding the problem of operational errors threatening personal safety due to manual discharge of condensate.

[0039] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Fig. 9, including: a tank body 1, a tank cap 5, a buoy cap 7, a buoy barrel 9, a guide block 11, a positioning frame 14 and a mechanical valve. A bracket 2 is provided at the bottom of the tank body 1. The bracket 2 is composed of three inclined rods and an annular base. The three inclined rods are distributed along the circumferential direction of the annular base. The upper ends of the inclined rods are welded and fixed to the bottom of the tank body 1, and the lower ends of the inclined rods are welded and fixed to the annular base. A sewage outlet 3 is provided at the center of the bottom of the tank body 1. Corresponding to the sewage outlet 3, an automatic sewage pipe 301 protrudes from the center of the bottom of the tank body 1. A solenoid valve is provided on the sewage pipe 301. The solenoid valve is at When the autoclave is in a low-pressure state, the sewage pipe 301 is controlled to discharge impurities at the bottom of the tank body 1, providing convenience for the sewage discharge of the tank body 1; a water outlet 4 is provided at the lower right side of the tank body 1, and a water outlet pipe 401 is protruded from the outer wall of the tank body 1 corresponding to the water outlet 4. A silencer 22 is sleeved in the tube cavity of the water outlet pipe 401, and the tube wall of the silencer 22 is covered with honeycomb-shaped holes. The silencer 22 can reduce the noise generated by the condensed water discharged from the water outlet 4, providing a good working environment for the workers and a good work and rest environment for the people living nearby.

[0040] Reference Figure 1 , Figure 2 and Figure 3 The bottom of the tank cap 5 is butt-jointed with the top of the tank body 1 through a flange to form a condensate release chamber. A water inlet 6 is provided on the side of the tank cap 5. Corresponding to the water inlet 6, a water inlet pipe 601 connected to the condensate outlet of the autoclave is protruded from the outer wall of the tank cap 5 to allow the condensate to be discharged smoothly into the release chamber. The buoy cap 7 is located inside the tank cap 5. A eaves plate 8 protrudes horizontally outward from the bottom of the buoy cap 7. The eaves plate 8 corresponds to the joint between the tank body 1 and the tank cap 5, and a drop hole 801 is provided on the surface of the eaves plate 8. The eaves plate 8 is clamped between the flanges of the tank body 1 and the tank cap 5. The diameter of the buoy cap 7 is smaller than the inner diameter of the tank cap 5, so that the drop hole 801 on the eaves plate 8 is just in the release chamber.

[0041] Reference Figure 2 The buoy barrel 9 corresponds to the buoy cap 7 and is erected inside the tank body 1. The inner diameter of the buoy cap 7 is larger than the outer diameter of the buoy barrel 9, so that the buoy barrel 9 can smoothly enter the buoy cap 7 when floating up, and at the same time provide the buoy barrel 9 with space for displacement inside the buoy cap 7, because the buoy barrel 9 does not move vertically completely along a straight line during floating, but there is a certain offset; a connecting rod 10 extends downward from the center of the bottom of the buoy barrel 9.

[0042] Reference Figure 2 , Figure 4 and Figure 5The guide block 11 is welded and fixed to the right inner wall of the tank body 1 corresponding to the water outlet 4. A flow channel is provided inside the guide block 11. The flow channel inlet 12 is provided on the upper surface of the guide block 11, and the flow channel outlet 13 corresponds to the water outlet 4. The positioning frame 14 is fixed above the guide block 11 close to the inner wall of the tank body 1. The positioning frame 14 includes: a horizontal plate and a pair of vertical plates. Both ends of the horizontal plate are fixed to the right side of the upper surface of the guide block 11 by bolts. The two vertical plates are welded and fixed to the middle part of the horizontal plate at intervals. The vertical plate is used to connect the parts of the mechanical valve.

[0043] Reference Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The mechanical valve includes: a lifting rod 15 and a swing block 16. The right end of the lifting rod 15 is slightly bent upward and welded to the left bottom of the swing block 16. The left end of the lifting rod 15 is hinged to the lower end of the connecting rod 10. The swing block 16 is located above the guide block 11. A protrusion is provided at the end of the swing block 16 facing the water outlet 4, that is, the right end. The protrusion extends between the two vertical plates of the positioning frame 14 and is hinged through a pin shaft. Thus, the swing block 16 and the guide block 11 are connected as a whole through the positioning frame 14; a plugging head 17 is convex on the bottom surface of the swing block 16. The plugging head 17 on the bottom surface of the swing block 16 in a horizontal state falls on the flow channel inlet 12 to block it, that is, the size of the plugging head 17 must be larger than the flow channel inlet 12. Based on this, the flow channel inlet 12 can be unsealed by lifting the swing block 16, and then the fluid above the flow channel inlet 12 will automatically flow in.

[0044] In this embodiment, in order to facilitate the rapid molding of the plugging head 17 and to fit it with the flow channel inlet 12, a vertical channel 19 is first provided inside the pendulum block 16, and the channel 19 completely penetrates the pendulum block 16, and a ball plug is placed inside the channel 19, and the lower opening of the channel 19 is narrowed to block the ball plug. At this time, the part of the ball plug exposed to the channel 19 is the plugging head 17 mentioned above, and the ball plug can be made of rubber material, so as to ensure that the flow channel inlet 12 is tightly blocked; then a pressure rod 20 is inserted into the channel 19 to ensure that the lower end of the pressure rod 20 is in contact with the ball plug, and the pressure rod 20 pre-presses the ball plug to ensure the stability of the ball plug, and finally a cover plate 21 is provided on the top of the pressure rod 20, and the cover plate 21 is fixed to the top surface of the pendulum block 16 by bolts.

[0045] In this embodiment, a pair of support rods 18 protrude horizontally from the inner wall of the tank body 1. The support rods 18 are located below the buoy barrel 9. The two support rods 18 are in the same straight line, and the length direction of the support rods 18 is consistent with the direction of the water outlet 4. The support rods 18 are provided to ensure the stability of the buoy barrel 9 in the initial state, that is, the two support rods 18 are in contact with the bottom of the buoy barrel 9 in the initial state.

[0046] In this embodiment, the water outlet 4 is arranged at the lower right side of the tank body 1 in order to create a height difference with the sewage outlet 3 at the center of the bottom of the tank body 1 so that impurities in the condensed water can have enough space to accumulate at the bottom of the tank body 1.

[0047] In this embodiment, due to the design of the mechanical valve, the discharge channel of the condensed water can be set at about 10 mm. By narrowing the discharge channel of the condensed water, the anti-clogging performance of the device is improved, highlighting the product characteristics.

[0048] In actual use, due to the high pressure inside the autoclave, condensed water will be injected into the tank cap 5 along with gas through the water inlet pipe 601. The buoy cap 7 can prevent the jet from directly contacting the buoy barrel 9, thereby ensuring the stability of the buoy barrel 9 and preventing the mechanical valve from opening in advance to affect the stability of the release chamber and the autoclave system. The condensed water whose impact is mitigated by the buoy cap 7 enters the tank body 1 through the drop hole 801 on the surface of the eaves plate 8. When the liquid level of the condensed water in the tank body 1 buoys the bottom of the buoy barrel 9, the buoy barrel 9 It will be subjected to upward buoyancy. As the liquid level continues to rise, the float barrel 9 gradually rises, and the connecting rod 10 at the bottom of the float barrel 9 simultaneously lifts the left end of the lifting rod 15 upward, thereby lifting the left end of the pendulum block 16. The pendulum block 16 changes from horizontal to inclined, and the sealing head 17 on its bottom is separated from the flow channel inlet 12. At this time, the condensed water above the flow channel inlet 12 will be discharged to the outside through this port. During this period, the silencer 22 installed in the outlet pipe 401 reduces the noise of drainage and provides a good working environment.

[0049] The condensate automatic release device provided in this example can completely replace the manual automatic discharge of condensate inside the autoclave, saving time and effort. In the absence of manual participation, it can completely avoid the risk of operating errors, and naturally will not pose a threat to the personal safety of the staff.

[0050] It should be understood that the above description is merely exemplary and the embodiments of the present application do not limit this.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are within the scope of protection of the pending claims of the present invention.
