Embodiment 1

[0044] structured as figure 1 , Figure 3-5 , Figure 11 As shown, two needle valve type built-in reaction tanks 104 are arranged in a straight line in the main reactor. After their tank lids pass through the lid of the main reactor 101, they are connected to the main reaction tank with a gasket 107 and a fastening nut 106. Kettle connection, two external reaction tanks 105 are installed on both sides of the main reactor, and each of their two ends is connected to a valve 108, and then steel pipes are used to connect the main reactor lid and the opening on the side wall of the kettle. . The sequence, speed, and start and end of the reaction process are controlled by adjusting the opening and closing sequence of different reaction tanks. image 3 Among them, the built-in reaction tank 301 is connected to the tank cover 307 through threads, and two sealing valve blocks 303 and 304 are installed inside the tank body 301, which are respectively used to seal the upper and lower ...

Embodiment 2

[0046] structured as figure 2 , Figure 7-10 , Figure 11 As shown, a ball valve type built-in reaction tank is installed in the main reactor. After the tank cover of the ball valve type built-in reaction tank 104 passes through the still cover of the main reactor 101, the gasket 107 and the fastening nut 106 are connected to the main reactor. connect. Install 3 external reaction tanks outside the main reactor. They are evenly arranged above the main reactor. After each end is connected with a valve 108, the steel pipe is connected to the two openings on the lid of the main reactor. .

[0047] Figure 7 Among them, the ball valve type built-in reaction tank 701 is connected with the tank cover 707 through threads, and two sealing valve blocks 703 and 704 are installed inside the tank body 701, which are respectively used to seal the upper and lower channels 710 and 705 on the tank body. The two sealing valve blocks 703 and 704 are connected as a whole with the valve rod ...

Embodiment 3

[0050] As in Example 1, the difference is that a needle valve type built-in reaction tank and a ball valve type built-in reaction tank are installed in the main reactor, and an external reaction tank is installed outside the main reactor.
