Optionally, a first weight detector is arranged in the chlorination furnace 30, and the first weight detector is electrically connected with the controller;
The controller is configured to control the feeding assembly 10 to reduce the feeding speed when the value of the first weight detector is greater than the first set value, and/or control the feeding assembly 10 to increase the feeding speed when the value of the first weight detector is less than the first set value; the first set point is used to characterize the weight of raw materials that the chlorination furnace 30 is producing to consume.
The first weight detector may be provided at the bottom side of the chlorination furnace 30.
It should be appreciated that the first weight detector shows the weight of the reacted multiple raw materials in the chlorination furnace 30, and in case that the weight is less than the first set value, it is necessary to increase the feeding speed until the value of the first weight detector is the same as the first set value, avoiding the waste of heat of the heater 301.
For example, the reaction temperature of the heater 301 is 1100 ℃, and 0.5t of various raw materials can be reacted in one chlorination furnace 30 per unit time, at this time, only 0.3t of various raw materials are in the chlorination furnace 30, and at this time, the controller controls to increase the feeding speed, so that the weight in the chlorination furnace 30 reaches 0.5t, and the maximum reaction rate under the temperature condition is reached.
Similarly, in the case where the value of the first weight detector is greater than the first set value, the feeding assembly 10 is controlled to reduce the feeding speed so as to ensure the sufficient reaction of the raw materials.
In this embodiment, by arranging the first weight detector in the chlorination furnace 30, the first weight detector is electrically connected with the controller, and the controller controls the feeding speed based on the numerical value of the first weight detector, so as to realize automatic control of production, improve the production efficiency, and reduce the occurrence of incomplete reaction.

The controller is configured to control the feeding assembly 10 to increase the feeding speed in case the value of the first flow meter increases, and/or control the feeding assembly 10 to decrease the feeding speed in case the value of the first flow meter decreases.
It should be appreciated that the first flow meter is used to count the rate at which chlorine is provided by the chlorine providing device. Since the raw material needs to react with chlorine, the feeding speed is positively related to the supply speed of chlorine.
Illustratively, in the case where the value of the first flow meter is increased, at which time the chlorine supply is increased, it is necessary to control the feeding assembly 10 to increase the feeding speed so as to achieve the complete reaction; in the case of a decrease in the value of the first flow meter, at which time the chlorine available to participate in the reaction in the chlorination furnace 30 is decreased, the feeding assembly 10 needs to be controlled to decrease the feeding speed to achieve the complete reaction.
In this embodiment, by providing the first flowmeter at the third inlet of the chlorination furnace 30, the first flowmeter is electrically connected to the controller, and the controller controls the feeding assembly 10 to increase the feeding speed in the case that the value of the first flowmeter increases, and/or controls the feeding assembly 10 to decrease the feeding speed in the case that the value of the first flowmeter decreases, so as to achieve sufficient reaction in the chlorination furnace 30 and avoid waste of raw materials or chlorine.

It should be appreciated that the rate at which the gas treatment assembly 60 treats chlorine is constant, being the second set point. It is necessary to reduce the discharge rate of chlorine when the amount of chlorine is excessive, and the discharge rate of chlorine can be increased when the amount of chlorine is too small.
For example, in the case where the value of the gas detector is greater than the second set value, it is considered that the chlorine gas is discharged more at this time, and the controller is required to control the chlorine gas supply device to reduce the supply speed of the chlorine gas; in the case where the value of the gas detector is smaller than the second set value, it is considered that the chlorine gas discharge is small at this time, and the supply speed of the chlorine gas can be increased by controlling the chlorine gas supply device by the controller.
In this embodiment, by providing a gas detector at the sixth inlet of the gas processing module 60, the gas detector is electrically connected to a controller, and by the controller, in the case where the value of the gas detector is greater than the second set value, the chlorine providing device is controlled to reduce the providing speed of the chlorine; and/or under the condition that the value of the gas detector is smaller than the second set value, controlling the chlorine supply device to increase the supply speed of the chlorine, realizing complete treatment of the chlorine and reducing pollution.

The first scraper 502 may scrape the solid product on the inner wall of the first separator tank 50, thereby increasing the discharge amount of the solid product.

The second weight detector may be disposed at the bottom side of the first separation tank 50, and the first level gauge may be disposed at a side surface of the first separation tank 50.
It will be appreciated that in the case where the solid product of the fourth setpoint is separated in the first separator and the location of the solid product also meets the fifth setpoint, the separation of the solid product from the gas may be considered complete and it is desirable to pass the solid product into the discharge box 80.
In this embodiment, by providing the second weight detector and the first level indicator in the first separator tank 50, the second weight detector and the first level indicator are electrically connected to the controller, so that the controller controls the sixth outlet and the seventh inlet to be opened when the value of the second weight detector is less than or equal to the fourth set value and the value of the first level indicator is greater than or equal to the fifth set value, and the solid product enters the discharge tank 80 through the transmission assembly 70, thereby completing the production process.
Optionally, a third weight detector and a second level gauge are arranged in the second separation box 51, and the third weight detector and the second level gauge are electrically connected with the controller;
the controller is used for controlling the opening of the ninth outlet and the seventh inlet under the condition that the value of the third weight detector is smaller than or equal to a fourth set value and the value of the second level gauge is larger than or equal to a fifth set value
The third weight detector may be disposed at the bottom side of the second separation tank 51, and the second level gauge may be disposed at the side surface of the second separation tank 51.
It should be understood that the function of providing the third weight detector and the second level gauge in the second separator tank 51 is the same as the function of providing the second weight detector and the first level gauge in the first separator tank 50, and will not be described again here.
Optionally, a fourth weight detector is arranged in the discharging box 80 and is electrically connected with the controller;
the controller is configured to control the transmission assembly 70 to reduce the transmission speed in the case that the value of the fourth weight detector increases; and/or, in case the value of the fourth weight detector is reduced, the transmission assembly 70 is controlled to increase the transmission speed.
Wherein the fourth weight detector may be provided at the bottom side of the discharge bin 80.
It should be appreciated that the discharge bin 80 is used to store the solid product or to transfer the solid instructions to a wrapper for packaging. In the case that the value of the fourth weight detector increases, at this time, the remaining storable space in the discharge box 80 becomes small, and it is necessary to control the transfer assembly 70 to reduce the transfer speed; in the case of an increase in the value of the fourth weight detector, the remaining storable space in the tapping tank 80 at this time becomes large, so that the transfer speed of the transfer assembly 70 can be controlled.
