Description

Supply and Circulation System of Recycling Release Agent for Die Casting Process

The present invention relates to a supply and circulation system of a recycled release agent for a die casting process, and more particularly, a release agent purified by removing impurities included in a process in a release agent used to improve mold release properties between a mold and casting during injection in a die casting process. Can be recycled to the die-casting process, and also detects the level of the storage tank where the release agent is stored and automatically refills the new release agent when the low level is detected, and stops supplying and circulates when the storage tank detects the maximum level. The present invention relates to a supply and circulation system of a recycling release agent for a die casting process.

Generally, in the die casting process, a release agent is applied to the mold surface of the mold in order to easily separate the casting from the mold before injection of the casting. The release agent is applied by diluting to a suitable concentration with water, placing a spray device in the middle of both split molds with the mold open, and spraying along the mold surface.

When the die casting process is completed, the release agent applied to the mold surface is recovered and reused. Since the used release agent contains impurities such as oil or sludge, in order to reuse the release agent, impurities are effectively removed to the die casting apparatus. There is a need for a release agent cleaning device that allows resupply.

As a prior art related to cleaning and reusing a fluid such as a releasing agent, a releasing agent, an abrasive oil, a hydraulic oil, and the like used in a process of various machines including such a die casting device, the Korean Utility Model Registration No. 20-0249707 describes a cutting process. A description is given of a belt oil skimmer configured to remove waste oil from the spent oil of the used coolant liquid to reuse the coolant liquid.

The belt oil skimmer may move waste oil introduced into a storage tank to a separation tank using a belt, and then separate the waste oil by the difference in the specific gravity of the coolant liquid and the waste oil, and then reuse the purified coolant liquid in the production of the product. It is configured to be. The belt oil skimmer is configured to remove waste oil from the waste oil suspended in the storage tank by separating the waste oil sucked on the belt with a scraper and transporting it to the separation tank, but it is used in the cutting process and then stored in the storage tank. Since waste oil contained in the coolant liquid stored is applied to the surface by simply varying the specific gravity, there is a limit to quickly injuring and collecting impurities such as sludge including waste oil contained in the coolant liquid. There is a disadvantage in that the collection efficiency of relatively large sludge is low.

In another prior art, the apparatus for treating die-casting wastewater disclosed in Korean Patent Laid-Open Publication No. 10-2014-0055868 includes: a wastewater collecting tank for collecting wastewater generated after the diecasting process, and a chemical injection device for chemically treating the wastewater transferred from the wastewater collecting tank; A configuration including a flotation device for supplying bubbled water to the wastewater passing through the chemical injection device to float and remove condensed particles in the wastewater is shown.

A configuration includes a skimmer to remove the flocculated particles, a sludge storage tank in which the removed condensed particles are stored, a sludge outlet through which sludge is discharged, and a treatment tank to which the condensed particles are treated.

However, the apparatus for treating the die-casting wastewater has a possibility of further contamination due to the coagulant administered in the chemical injection device, and the micro-bubble generating device is configured to promote the generation of bubbles by using only the pressure of the pressure pump. However, this configuration alone has a disadvantage in that there is a limit to ultrafine microbubbles in units of several micrometers.

In addition, the die casting washing wastewater treatment device is insufficient to detect and automatically replenish when the capacity of the release agent by the repeated reuse of the release agent is insufficient in the configuration to supply the release agent at the time of repeated operation of the device There is a problem that comes with discomfort.

The recycling release agent in the storage tank 300 is continuously stirred by the stirrer 309, and is supplied to the supply pump part 1000 through the three-way valve 402. The controller 1100 opens one side of the storage tank 300 filled up to the upper limit of the three-way valve 402 to supply a recycling release agent to the supply pump unit 1000, and recycles release of any one storage tank 300. When all of them are discharged to the supply pump part 1000, the other side of the three-way valve 402 is opened to supply the recycled release agent to the supply pump part 100. As the other side of the three-way valve 402 is opened, one side is automatically shut off. When it is detected that the water level is discharged to the lower limit through the three-way valve 402, the controller 1100 opens the second control valve 501 for draining, and only when the second control valve 501 is opened. The release agent containing some impurities is introduced back into the input tank 700 through the recirculation pipe part 500. Therefore, the storage tank 300 can maintain a clean state because all of the release agent containing some impurities are drained.

In addition, the controller 1100 drives the stirrer motor 308 to continuously stir when the storage release agent 300 is filled with the recycling release agent.

When the recycled release agent is supplied through the three-way valve 402, the controller 1100 drives the supply pump 1001, and the recycled release agent is transferred to the die casting apparatus by the supply pump 1001.

The controller 1100 instructs the opening and closing of the valve and the driving of the pump to repeat this process.

In the present specification, the supplying and circulating system of the releasing agent used in the die casting process as an example, and the recycling releasing agent, but the purifying fluid of the present invention can be carried out for the purification and recycling of the fluid used in the process of various devices in addition to the release agent. It is obvious that such modifications also fall within the scope of the present invention.

The present invention relates to a supplying and circulating system of a release agent for recycling a release agent used in a die casting process, and is an invention having high industrial applicability in terms of increasing the recyclability of the release agent.
