However, paper products are still irreplaceable in other applications, and therefore, the continuous development of the paper industry is also very important.

High molecular polysaccharide and protein generated by microbial metabolism can adsorb suspended solids in pulp, metabolites of microbes can be brought into the pulp to form rotten pulp in various pipelines and equipment through which the pulp and white water flow, and phenomena of paper breakage, holes, spots and the like can be caused if the generated rotten pulp is mixed into paper making pulp, so that the dust degree of the paper is increased, the rejection rate is increased, and in order to solve the problems, the injection of a bactericide in the paper making process is particularly important.

The method for intelligently injecting the bactericide in the papermaking process shown in fig. 1 is applied to a bactericide injection system, the bactericide injection system can comprise a timing device, a main control device and an injection device, and the injection device comprises a storage device for containing the bactericide. As shown in fig. 1, the method for intelligently injecting a bactericide in a papermaking process may include the following operations:

101. the timing device starts timing in the papermaking process and sends the current timed moment to the main control device.

In the embodiment of the invention, the timing device can continuously and uninterruptedly time from the initial procedure of the papermaking process, also can continuously time from the initial procedure of the papermaking process for the first time until the current time of the timing reaches a certain time needing to be injected with the bactericide, after the bactericide is injected, the timing device is cleared and restarts to continuously time until the current time of the timing reaches a certain time needing to be injected with the bactericide, and so on. Wherein the timing device may be a pulse timer.

In an optional embodiment, before the timing device sends the current time counted by the timing device to the master control device, the timing device may further perform the following operations:

the timing device judges whether the current timing time reaches a certain time needing to be injected with the bactericide, and if the judgment result is yes, the operation of sending the current timing time to the main control device is executed. Therefore, the current time timed by the timing device is sent to the main control device under the condition that the current time timed by the timing device reaches a certain time needing to be injected with the bactericide, so that unnecessary judgment operations of the main control device can be reduced, and the judgment accuracy of the current time can be improved in a double judgment mode.

102. And the main control device receives the current time sent by the timing device, detects whether the current time reaches the predetermined bactericide injection time, and triggers to execute the step 103 when the detection result is yes, and can end the process when the detection result is no.

In the embodiment of the present invention, the predetermined bactericide injection time may be input to the main control device by a corresponding person in charge or an operator before the paper making process starts, stored by the main control device, intelligently determined by the main control device according to a specific process of the paper making process, determined by the main control device according to the content of microorganisms (i.e., "bacteria") in a designated addition point, or determined by the main control device according to a currently adopted paper making process and a combination of paper making raw materials, which is not limited in the embodiment of the present invention.

In an alternative embodiment, when the current result of step 102 is no, the master control device may further perform the following operations:

the main control device judges whether the content of the microorganisms contained in the appointed adding point exceeds the preset minimum content, and when the judgment result is yes, the main control device determines the target type of the target bactericide to be injected and the target dosage to be injected, and triggers and executes the step 104 and the step 105.

Therefore, the optional embodiment can not only realize the intelligent and automatic injection of the bactericide in a timing mode, but also realize the intelligent and automatic injection of the bactericide in a mode of judging the content of microorganisms in the appointed feeding point.

103. The main control device determines the target type of the target bactericide to be injected and the target dosage to be injected at the predetermined bactericide injection time.

In the embodiment of the present invention, it should be noted that the target dose is in a dose range corresponding to the target type, that is, the target dose is greater than or equal to a minimum value in the dose range corresponding to the target type and is less than or equal to a maximum value in the dose range corresponding to the target type, so that situations that sterilization cannot be performed and bacterial propagation cannot be inhibited due to too little injection of the bactericide can be reduced, and situations that the bactericide is wasted and the cost is increased due to too much injection of the bactericide can be avoided. The dosage range corresponding to the target type can be further determined by the currently adopted papermaking process and the type and the dosage of the papermaking raw materials.

104. The main control device generates a control signal carrying the target type and the target dose, and sends the control signal to the injection device.

In this embodiment of the present invention, the main control device may send the control signal to the injection device in a wired manner, or may send the control signal to the injection device in a short-distance wireless communication manner, which is not limited in this embodiment of the present invention.

105. And the injection device receives the control signal sent by the main control device and controls the storage device to inject the target bactericide with the target dosage into the designated adding point according to the control signal.

In an alternative embodiment, after step 104 is completed, the method for intelligently injecting a bactericide during the paper-making process may further include the following operations:

the main control device judges whether a receiving confirmation message fed back by the injection device is received, wherein the receiving confirmation message is used for indicating that the injection device has received the control signal, and when the receiving confirmation message is not received, the main control device judges whether the total times of sending the control signal to the injection device reaches a preset time threshold (such as 3 times);

when the total number of times of sending the control signal to the injection device does not reach the preset number threshold, continuing to trigger and execute step 104; when the total times of sending the control signals to the injection device reaches a preset time threshold, the main control device sends out an alarm prompt, and the alarm prompt is used for indicating that the communication between the main control device and the injection device is abnormal, so that a person in charge can timely detect and eliminate faults.

Therefore, the alternative embodiment can reduce the situation that sterilization is not timely caused by communication failure between the main control device and the injection device.

Therefore, the method for intelligently injecting the bactericide in the papermaking process described in the figure 1 can automatically time in the papermaking process, and quantitatively inject the determined bactericide into the specified adding point when the timed real-time reaches the bactericide injection time, so that the intelligent and automatic injection of the bactericide is realized, the manpower input is reduced, the accuracy and the reliability of the bactericide injection are improved, the sterilization efficiency and the success rate of the bactericide are improved, and the papermaking yield is improved.
