DETAILED DESCRIPTION

[0017] The following is a further detailed description of the present invention in conjunction with the accompanying drawings, clearly and completely describing the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] like Figure 1 and Figure 2 As shown, a pressure regulating device for reactor production includes a reactor body 1, a reactor cover 2, a stirring motor 3, a coupling 4, an agitator 5, a solid feed port 6, a liquid feed port 7, a pressure regulating mechanism 8 and a foot 9. The reactor cover 2 is sealed on the reactor body 1, the stirring motor 3 is installed on the top of the reactor cover 2, and the agitator 5 inside the reactor body 1 is connected to the stirring motor 3 through the coupling 4. The solid feed port 6 and the liquid feed port 7 are installed on the reactor cover 2, and valves are installed on both feed ports. The pressure regulating mechanism 8 is also installed on the reactor cover 2, and the foot 9 is installed at the bottom of the reactor body 1. The pressure regulating mechanism 8 includes a valve body 15, a valve block 16, a valve cavity 17, a spring 18, a stop block 19, a connecting hole 20, a filter block 21, an exhaust port 22, a valve port 23, an adjusting screw 24 and a screw cap 25. The valve body 15 is fixedly mounted on the kettle cover 2. The valve cavity 17 is located in the inner cavity of the valve body 15. The valve block 16, spring 18 and stop block 19 are sequentially mounted inside the valve cavity 17 from bottom to top. The side wall of the valve cavity 17 is provided with a communicating hole 20, which is communicated with the exhaust port 22. The filter block 21 is mounted at the outlet position of the exhaust port 22. The valve port 23 connects the inner cavity of the kettle body 1 with the valve cavity 17. The adjusting screw 24 is threadedly engaged with the valve body 15. The end of the adjusting screw 24 extends into the valve cavity 17 and abuts against the stop block 19, and pushes the stop block 19 to compress the spring 18. The elastic force of the spring 18 pushes the valve block 16 against the valve port 23, so that the communicating hole 20 is separated from the valve port 23. The screw cap 25 is arranged at the outer end of the adjusting screw 24. A pressure gauge can be installed on the kettle cover 2 to monitor the pressure inside the kettle body 1.

[0019] Further, such as Figure 3 As shown, a scale plane 26 is provided on the side of the adjusting screw 24 , and a scale 27 is provided on the scale plane 26 . The pressure value of the valve block 16 is read through the scale 27 on the scale plane 26 .

[0020] Furthermore, the connection positions of the kettle body 1 and the kettle cover 2 are both provided with connection flanges 11, which are sealed by a sealing gasket 12 and fixedly connected by bolts 13 passing through the connection holes on the connection flanges 11. They can also be fixed by means of a clamping block. The sealing of this connection position needs to be verified.

[0021] Furthermore, the side wall of the kettle body 1 is provided with an air pressure connector 14 connected to the air source, and a valve is installed on the air pressure connector 14. The air source can be a high-pressure pump or a negative pressure pump to form a negative pressure inside the kettle body of the device. If a negative pressure is formed inside the kettle body, the pressure regulating mechanism mainly plays the role of isolating the outside.

[0022] Furthermore, a jacket 10 is provided on the outside of the kettle body 1 , and the temperature inside the kettle body 1 can be controlled by adding hot water or cold water into the jacket 10 .

[0023] Furthermore, the number of the connecting holes 20 and the exhaust ports 22 is multiple and equal. The multiple connecting holes 20 and the exhaust ports 22 can avoid the blockage of a certain path and affect the operation of the pressure regulating mechanism.

[0024] The utility model can conveniently adjust the pressure inside the kettle body by arranging the pressure regulating mechanism. The pressure regulating mechanism is a purely mechanical structure and has the advantages of being reliable and stable.
