The solution in which the pulp raw material is dissolved at a predetermined ratio is supplied to a forming mold provided in a paper machine, and moisture is removed to form a desired shape. In this case, the quality of the produced product is fixed. In order to increase the productivity and to increase the productivity, the pulp concentration of the solution must be maintained at a predetermined ratio, managed and supplied. Therefore, the present invention relates to a system for maintaining and supplying a pulp solution at a constant ratio, and for example, a pulp solution supply system for producing paper containers for storing and moving food will be described.

According to an example of the present invention with reference to FIG. 1, the pulp solution supply system for paper containers will be described in detail. The pulp and purified dilution water are introduced into the raw material tank 110 of the raw material tank means 100, and a stirrer is used. Drive to allow the pulp to dissolve quickly in dilute water.

Since the pulp is a fiber extracted from a plant such as a tree, and water is removed, the pulp is a relatively hard solid state such as a piece of wood. When the pulp is added to water, the pulp is dissolved for a predetermined time and becomes a state of porridge. Agitators are used to reduce this dissolution time. The stirrer is provided with a motor at one end and a rotating blade is attached at the other end to stir for a predetermined time, so that the solidified pulp is quickly dissolved in dilute water.

The concentration of the pulp dissolved by tapping and mixing from the raw material tank means 100 for a predetermined time is preferably 0.4%, for example, for the outflow of the solution and the improvement of the productivity of the product.

The pulp stock solution, which has been dissolved at a concentration of 0.4% by the raw material tank means 100, for example, is discharged to the combination tank means 300 by the pump 120, and is filled up to the “H” level of the combination tank 310. .

After each dilution is completed, the chemical liquid is discharged to the combination tank 310 of the combination tank means 300 and mixed with the pulp solution, and the mixing order and the amount are different.

Since the pump 220 is turned on to control the chemical liquid designated by the set order by the set amount, the pump 220 flows out to the combination tank 310 and detects and confirms the amount added by the flowmeter 230. Be sure to

The addition of the next chemical solution is preferably added after about 3 minutes, for example.

At this time, the combination tank means 300 continues to operate the stirrer so that the concentration of the pulp solution is kept constant so that the outflowing chemical liquid is added evenly. The combination tank means 300 detects whether the pulp solution leaked by the detection means is stored at the H level and the L level, and notifies the control unit 500, thereby displaying a corresponding signal or a warning signal.

The process of adding the chemical liquid may be automatically discharged by the control and monitoring of the control unit 500.

When the discharge of the pulp solution and the addition of the chemical solution to the combination tank 310 of the combination tank means 300 is completed and concentration adjustment is completed, the pump 320 is controlled manually or automatically to supply H of the supply tank means 400. It spills down to a level so that it can be stored and secured and the paper container can be stably produced.

When the supply tank means 400 detects that the pulp solution is stored at the M level by the detection means, it notifies the controller 500 to block the operation of the pump 320. The control unit 500, for example, by the level detection information of the supply tank means 400, if the M level is detected to display the corresponding pulp solution from the combination tank means 300, and if the L level is detected, the corresponding display At the same time to block the operation of the pump 420 to supply and supply the stored pulp solution to the paper machine 600.

The paper machine 600 is returned to the supply tank 410 through the overflow (OVERFLOW) when the pulp solution flowing out of the pump 420 is supplied in an appropriate amount or more so as not to be wasted.

The paper machine 600 is provided with a mold and a gold mesh of a selected shape, and removes moisture from the pulp material supplied outflow and heats and solidifies the pulp filtered through the gold mesh to produce a paper container of a desired shape.

With reference to FIG. 2, the manual operation method of the pulp solution supply system for paper containers is demonstrated by an example of this invention.

The control unit 500 of the system detects and confirms the pulp solution storage level of the combination tank 310 and the supply tank 410 (S100).
