[0024] The kettle cover 2 is connected with the kettle flange 1 for closing the kettle 1, preventing the material leakage and the outside impurities into the inside of the kettle 1, keeping the pure environment of the reaction, the direct current motor 3 is installed in the middle position of the top surface of the kettle cover 2, and the stirring shaft 11 penetrates one end of the kettle cover 2 and is connected with the shaft of the direct current motor 3, so that when the direct current motor 3 is opened by the external control system, the direct current motor 3 drives the stirring shaft 11 to rotate after the speed reducer reduces the speed, so that the rotating stirring shaft 11 stirs the material in the kettle 1 to increase the reaction degree of the material in the kettle 1. The material enters the kettle 1 from the two feed ports 4 on the top surface of the kettle cover 2, the liquid level sensor 12 installed on the top surface of the kettle cover 2 is an ultrasonic liquid level sensor 12, which emits an ultrasonic signal in the kettle 1, the emitted ultrasonic signal is reflected on the interface of the liquid, the control circuit of the liquid level sensor 12 receives the ultrasonic signal reflected by the liquid and converts it into an electric signal, and the liquid level sensor 12 receives the electric signal after processing to calculate the liquid level of the liquid. Four supports 10 are arranged on the bottom surface of the kettle 1 for supporting the kettle 1, the liquid discharge pipe 5 is arranged on the bottom surface of the kettle 1, the liquid in the kettle 1 is discharged from the kettle 1 through the liquid discharge pipe 5, the ball valve 7 is arranged on the bottom surface of the liquid discharge pipe 5, and the first electric control valve 8 is arranged on the bottom surface of the ball valve 7. The liquid enters the ball valve 7 through gravity after entering the liquid discharge pipe 5, and enters the first electric control valve 8 through the ball valve 7, and is discharged from the first electric control valve 8. The first electric control valve 8 and the second electric control valve 9 can be connected with the external pipeline, the side pipe 6 is integrally formed with the liquid discharge pipe 5, when the first electric control valve 8 is damaged, the pipeline to the first electric control valve 8 can be closed by the ball valve 7, so that the liquid cannot enter the first electric control valve 8 by gravity, when the second electric control valve 9 is opened, the liquid blocked by the ball valve 7 will enter the second electric control valve 9 through the side pipe 6 of the liquid discharge pipe 5, and the liquid blocked by the damaged first electric control valve 8 is discharged from the kettle 1 through the second electric control valve 9.

[0025] When the liquid level sensor 12 is used, the liquid level in the reactor 1 is monitored in real time. When the liquid level reaches the set liquid level, the liquid level sensor 12 transmits an electrical signal to the control system of the reactor 1. The control system determines whether the liquid level meets the discharge condition according to the signal, and then controls the opening and closing of the first electric control valve 8. When the first electric control valve 8 is opened, the liquid in the reactor 1 is discharged through the bottom discharge pipe 5, enters the ball valve 7, and then enters the first electric control valve 8 and is discharged through the first electric control valve 8. When the first electric control valve 8 is damaged and cannot discharge the liquid, the second electric control valve 9 can be opened by the external control system. When the liquid enters the discharge pipe 5, it cannot pass through the first electric control valve 8. After the liquid is discharged from the reactor 1, it enters the second electric control valve 9 through the side pipe 6 and is discharged through the opened second electric control valve 9. When the liquid is discharged from the second electric control valve 9, the ball valve 7 is rotated to close the passage to the first electric control valve 8, so that the liquid cannot enter the first electric control valve 8 from the ball valve 7. When the liquid cannot enter the first electric control valve 8, the first electric control valve 8 can be removed from the bottom of the ball valve 7 for maintenance. Specific embodiment two:

[0027] Referring to Figures 1-4 , an automatic liquid discharge device in a polyaluminum chloride preparation system, further based on the basic structure in specific embodiment one, the discharge pipe 5 can be replaced from an integrated type to a modular type. The discharge pipe 5 is connected to the flange at the liquid outlet on the bottom surface of the reactor 1. When the discharge pipe 5 is damaged after long-term use, the bolt latch of the discharge pipe 5 can be removed, and the damaged discharge pipe 5 can be replaced with a new one, preventing the need to repair or replace the entire reactor 1 when the discharge pipe 5 is damaged.

[0028] In summary:

[0029] 1. A side pipe 6 is provided on the surface of the discharge pipe 5, a ball valve 7 is installed on the bottom surface of the discharge pipe 5, a first electric control valve 8 is installed on the bottom surface of the ball valve 7, and a second electric control valve 9 is installed on the surface of the side pipe 6. When the first electric control valve 8 is damaged and cannot automatically discharge the liquid, the second electric control valve 9 can be opened by the external control console. When the liquid enters the discharge pipe 5, it cannot pass through the first electric control valve 8. After the liquid is discharged from the reactor 1, it enters the second electric control valve 9 through the side pipe 6 and is discharged through the opened second electric control valve 9. When the liquid is discharged from the second electric control valve 9, the ball valve 7 is rotated to close the passage to the first electric control valve 8, so that the liquid cannot enter the first electric control valve 8 from the ball valve 7. When the liquid cannot enter the first electric control valve 8, the first electric control valve 8 can be removed from the bottom of the ball valve 7 for maintenance, without stopping the reactor 1. This solves the problem of being unable to automatically discharge the liquid when the electric control valve is damaged, and also solves the problem of being unable to maintain the electric control valve without stopping the reactor 1.
