Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recycle release agent for die casting processes,

The present invention relates to a supply and circulation system for a recycling release agent for a die casting process, and more particularly, to a system for supplying and recycling a recycled release agent for a die casting process by removing impurities contained in the process from the mold release agent used for improving the mold- And a new release agent is automatically replenished when the low water level is sensed. When the water level of the storage tank is detected at the maximum water level, the supply is stopped and the circulating water is circulated To a supply and circulation system for a recycling release agent for a die casting process.

Generally, in a die casting process, a release agent is applied to a mold surface to easily separate a casting from a mold before injection of the casting. The releasing agent is diluted to an appropriate concentration using water, and is sprayed along the mold surface by placing a spray device in the middle of the split molds with the mold open.

When the die casting process is completed, the mold release agent applied and used on the mold surface is recovered and reused. Since the release agent used contains impurities such as oil or sludge, the mold release agent is effectively removed to re- A mold releasing agent cleaning device capable of re-supplying the mold releasing agent.

As a prior art related to cleaning and reusing fluids such as a release agent, a release agent, a polishing oil, and an operating oil used in a process in various kinds of machinery including such a die casting apparatus, Registration Practical Utility Model No. 20-0249707 A technical description of a belt oil skimmer configured to reuse the coolant liquid by removing waste oil from the used coolant liquid waste oil is shown.

In the belt oil skimmer, the waste oil flowing into the storage tank is moved to a separation tank by using a belt, the waste oil is separated by the difference in specific gravity between the coolant and the waste oil, and the purified coolant is re- . The belt oil skimmer is configured to remove waste oil from waste oil suspended in a storage tank by separating the waste oil sucked on the belt by a scraper and transferring the waste oil to a separation tank. However, Since the waste oil contained in the coolant to be stored is simply applied to the surface by the difference in specific gravity, there is a limit in collecting the impurities such as sludge including the waste oil contained in the coolant liquid, The collection efficiency of the relatively large sludge is low.

In another prior art, the apparatus for treating diecasting washing wastewater disclosed in Japanese Patent Laid-Open No. 10-2014-0055868 includes a wastewater collecting tank for collecting wastewater generated after a die casting process, a chemical injecting device for treating wastewater transferred from the wastewater collecting tank, And a floating separation device for supplying bubble water to the wastewater that has passed through the medicine injection device to float and remove the coagulated particles in the wastewater. The floating separator includes a micro-bubble generator for generating micro-bubbles by a pressurizing pump, a mixing tank for mixing the micro-bubbles supplied from the micro-bubble generator and the wastewater passing through the drug injector, A skimmer for removing floated coagulated particles, a sludge storage tank for storing the removed coagulated particles, a sludge discharge port for discharging the sludge, and a treatment water tank for moving the treated water with the coagulated particles.

However, the apparatus for treating the die-casting washing wastewater is liable to cause additional contamination due to the coagulant to be injected in the chemical injector, and the micro-bubble generator is configured such that the generation of bubbles is promoted by using only the pressure force by the pressurizing pump However, this configuration has a disadvantage in that there is a limit in miniaturization of minute bubbles by several micrometers.

In addition, when the capacity of the mold release agent is insufficient due to the repeated reuse of the mold release agent, the apparatus for treating the die casting washing wastewater is required to supplement the mold release agent repeatedly when the apparatus is repeatedly operated, There is a problem that inconvenience is followed.

It is another object of the present invention to provide a system and a method for detecting a level of a storage tank in which a purified release agent is stored, automatically supplying a new release agent when the low water level is sensed, To provide a recycling release agent for a die casting process.

It is a further object of the present invention to provide a pair of storage tanks in which the purified recycled release agent is stored so that when the recycled release agent in one storage tank is all used the recycle release agent in the other storage tank is automatically used And to provide a recycling system for the recycling release agent for a die casting process which can keep the inside of the storage tank clean at all times by draining the remaining recycled release agent in another storage tank.
