Description

A kind of circulating cooling water purification method

【Technical field】

The invention belongs to the technical field of moulds, and in particular relates to a method for purifying circulating cooling water.

【Background technique】

In the traditional water tower and the water pipes that transport cooling water, algae plants will grow and dust will float into the cooling tower for a long time to deposit, which will eventually lead to blockage of the water system or poor water flow; which will cause the mold temperature to rise and affect the normal operation of injection molded parts. Production, and the pipeline cleaning workload is very large, time-consuming and laborious, and the steps are cumbersome.

The present invention is produced based on the above problems.

【Content of invention】

The purpose of the present invention is to propose a method for purifying circulating cooling water aiming at the deficiencies of the prior art.

In order to solve the above technical problems, the present invention provides the following technical solutions: a method for purifying circulating cooling water, characterized in that it comprises the following steps:

A. The external tap water is first filtered by the sand filter device, and then enters the water supply device, and the stored water in the water supply device is circulated and filtered by the sand filter device;

B. The water supply device is equipped with a first air bubble generating device, which generates air bubbles in the water supply device, and then the water with air bubbles enters the mold temperature controller and flushes the passing water pipe;

C. After the tap water passes through the mold temperature machine to heat up or cool down, it passes through the second bubble generating device, and the bubbles generated by the second bubble generating device are sent to the inside of the mold waterway to take away the rust in the mold waterway;

D. The tap water flowing out of the mold passes through the magnetic stone, absorbs the metal impurity particles in the water, and then passes through the mold temperature machine for heat exchange;

E. The water after heat exchange returns to the waste water recovery device installed in the water supply device for filtration;

F. Repeat steps A to E.

A method for purifying circulating cooling water as described above is characterized in that the water supply device is a cooling water tower.

Compared with the prior art, a method for purifying circulating cooling water of the present invention has the following beneficial effects:

The present invention adds a circulating filtration and purification system between the cooling water tower, the mold temperature controller and the mould, such as the first air bubble generating device and the sand filter device, to filter and purify the circulating water, which can effectively avoid water blockage and affect normal injection molding. To ensure the normal production of injection molded parts, the purification method saves time and effort.

Fig. 1 is a structural representation of implementing the present invention;

Description of drawings: 1. Sand filter device; 2. Water supply device; 3. Mold temperature controller; 4. Mold; 5. First bubble generator; 6. Second bubble generator; 7. Magnetic stone; 8. Wastewater recovery device.

【Detailed ways】

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

As shown in Figure 1, in the present embodiment, a method for purifying circulating cooling water comprises the following steps:

A. The external tap water is first filtered through the sand filter device 1, and then enters the water supply device 2. At the same time, the stored water in the water supply device 2 is circulated and filtered through the sand filter device 1; the sand filter device first filters the tap water to ensure that it enters the water supply The water in the device is pure, and at the same time, the stored water in the water supply device 2 is repeatedly circulated and filtered through the sand filter device 1.

B. The water supply device 2 is provided with a first air bubble generating device 5, which generates air bubbles in the water supply device 2, and the water with air bubbles then enters the mold temperature controller 3, and flushes the passing water pipe;

C. After the tap water is heated or cooled by the mold temperature machine 3, the bubbles generated by the second bubble generator 6 are sent to the inside of the water channel of the mold 4 through the second bubble generator 6, and the rust in the water channel of the mold 4 is taken away;

D. The tap water flowing out from the mold 4 passes through the magnetic stone 7, absorbs the metal impurity particles in the water, and then passes through the mold temperature controller 3 for heat exchange;

E, the water after the heat exchange is returned to the waste water recovery device 8 arranged in the water supply device 2 for filtration and circulation;

F. Repeat steps A to E.

The present invention adds a set of circulating filtration and purification system between the water supply device, the mold temperature controller and the mold, such as the first air bubble generating device and the sand filter device, so as to filter and purify the circulating water quality, which can effectively avoid the blockage of the waterway from affecting the normal injection molding, To ensure the normal production of injection molded parts, the purification method saves time and effort.
