Description

A glue preparation production line

technical field

The utility model relates to the technical field of papermaking and energy saving, in particular to a glue preparation production line.

Background technique

The traditional method for sizing production of high-strength corrugated paper in existing paper mills is to set up several glue pots, the operator adds an appropriate amount of water into each pot, then turns on the agitator, pours in an appropriate amount of starch, and turns on the steam after stirring evenly. Heating, after a proper time, the glue is heated and matured, and the pump is turned on to pump out the clinker, and then the next round of circulation is carried out. In the traditional production process in the past, the following disadvantages were highlighted:

1. Because the amount of water added by manual treatment depends entirely on the naked eye, the speed of opening and closing the valve and misreading the line of sight will lead to errors in the amount of water, resulting in unstable concentrations;

2. The amount of starch added is also cumbersome due to manual weighing, and it is inconvenient to modify the amount of formula added;

3. Adding auxiliary raw materials by manual weighing is also difficult to accurately control the manual measurement scale, resulting in the addition of high and low amounts;

4. The control of the heating time during the steam heating process depends entirely on manual reading of the watch. When the number of pots is large, it is often too busy, which delays the best time to stop heating, or the temperature rise curve cannot be adjusted in time as required. The concentration and viscosity of clinker and other performance indicators are uneven;

5. The introduction of various errors such as the above will often lead to unqualified clinker, resulting in economic waste, and unqualified products can only be discharged into the sewage ditch and flow into the sewage treatment workshop for treatment, which increases the water treatment pressure of the environmental protection workshop.

Therefore it is necessary to improve it.

The use of automated production instead of manual production reduces the waste of resources and reduces the labor intensity of staff. It solves the problem that manual operation sometimes does not operate in time, resulting in a very large weight error in adding water or materials, and the quality is guaranteed. There is no need to discharge unqualified products into the ditch, making a positive contribution to environmental protection, energy saving and environmental protection. The output end of the dissolution tank 4 communicates with the input end of the temporary storage tank 5 , the output end of the dissolution tank 4 is provided with a second control valve 14 , and the output end of the second control valve 14 is provided with a discharge motor 15 .

The input end of the starch raw material bin 1 is provided with a hoisting device 20 for conveying the starch raw material.

The dissolution tank 4 is used for dissolving raw materials, and PLC is used instead of manual valve control and weighing measurement. In order to avoid the error of manual measurement. After dissolving, feed materials to each boiling pot 3 respectively, so that the proportioning ratio of water, starch and auxiliary materials can be guaranteed to be uniform. After being sent to the cooking pot 3, the automatic steam valve and the water valve are controlled by the PLC instead of the manual according to the set formula, the boiling time and other parameters, and a series of processes are executed. Because the PLC can be multi-threaded, multiple valves and multiple cooking stages can be carried out simultaneously without interfering with each other. Therefore, many uncontrollable factors introduced by manual processing are completely eliminated. No more rejects are generated.

In this embodiment, the signals detected by the weight sensor 9 and the liquid level sensor 10 are used to process the data to know whether the current dissolving tank 4 is empty. If it is empty, then send an instruction to close the vibration motor 6 and the feeding motor 7, stop feeding, open the first control valve 12, and water will flow into the dissolving tank 4, when the data of the weight sensor 9 and the liquid level sensor 10 are detected If it meets the pre-calculated value of the process index, close the first control valve 12, and send the data obtained by weighing and liquid level back to the PLC controller, and then calculate how much starch needs to be added according to the concentration, liquid volume, density, etc. How much it weighs together with water, and the value converted from volume to liquid level is all converted by PLC controller. Then start the feeding motor 7 and the vibrating motor 6, automatically add the starch from the raw material bin into the dissolving tank 4, and start the stirring mechanism 19, so that the material is evenly stirred. When all sensing data of weight sensor 9 and liquid level sensor 10 have just reached the expected value converted in advance, a stop instruction is sent immediately to stop feeding motor 7 and vibrating motor 6 . Calculate how much auxiliary material should be added according to the total amount of material at this moment, automatically start the metering pump 13 to add an appropriate amount of auxiliary material, and then stop the addition of auxiliary material. The stirring time can be preset to the required value in the PLC controller. When the time is up after fully stirring, the discharge motor 15 is automatically started, the second control valve 14 is opened, and the material is put into the temporary storage tank 5 for use. The temporary storage tank 5 sends the material into the boiling pot 3 through the solution feeding pump 16, and the boiling pot 3 automatically stops feeding after detecting the addition amount set in advance. Open and add the 3rd control valve 18 valves, start heating. The heating can adjust the heating temperature in real time according to the temperature measured by the temperature sensor. After heating for a long time under different temperature curves, switch to a new heating temperature, and finally cook a suitable clinker according to a suitable heating curve. After boiling is finished, open the third control valve 18 and automatically unload to the clinker storage tank.
