Description

Recycling and ready-to-use device for demoulding water

Technical field

The invention relates to the technical field of demolding water treatment, in particular to a ready-to-use device for demolding water recovery.

Background technique

In the process of precision die casting production of castings, due to high temperature, high pressure, and high speed, the liquid metal soup injected into the mold cavity at high speed is still as high as 400 degrees when it reaches the mold cavity, and the temperature of the mold surface is less than 200 degrees. The large temperature difference causes the unavoidable sticking phenomenon, so spraying release water on the mold surface to prevent sticking has become a necessary process. However, when the spray is sprayed on the mold surface, apart from a part of it is absorbed by the mold surface, there is still nearly one-third of the mold release water that escapes when the airflow collides and atomizes, and because a part of the mold release water that has not been atomized to form a water column is directed to the mold surface A lot of drain below.

Traditionally, the countermeasures adopted are to follow the free flow into the underground ditch and mix it with waste oil, waste water and garbage. So far, although some companies have installed large water pans at the bottom of the die casting machine, they will also change the mold release water in the future to pollute the environment and waste. The current state of the resource. The expensive electrostatic or plasma adsorption technology from Germany uses voltage to generate static electricity or plasma, which can absorb dust and smoke under the action of static electricity or plasma. Its cost is very expensive because of the large consumables and the low efficiency and the need for additional electrical equipment. Recycling a large amount of demolding water flowing down the mold is still a typical symptom and not a root cause.

The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings. It should be noted here that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation to the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

As shown in FIGS. 1 and 2, an embodiment of the present invention provides a mold release water recovery ready-to-use device 100. The mold release water recovery ready-to-use device includes a ready-to-use device main body 110, and the internal space of the ready-to-use device main body 110 is horizontal The direction is divided into a first space 111, a second space 112, and a third space 113 in sequence. The first space 111 is externally connected with the demolding water spray inlet 120 and the suction hood 130. The bottom of the second space 112 is adjacent to the side of the first space 111 with a demolding water recovery tank 140 pre-stored with demolding water, and the demolding water is recovered The side of the tank 140 adjacent to the first space 111 is connected to the first space 111, and the side of the demolding water recovery tank 140 away from the first space is provided with an inlet pipe 12 with a water pump 11 and a water outlet pipe 14 with a pressurized water pump 13 respectively. . A self-excited tapping device 150 and a hedging stirring device 160 are sequentially arranged above the liquid surface of the demolding water recovery tank 140. The bottom of the second space 112 is adjacent to the third space 113 and connected to the third space 113, and the top of the third space is arranged There is a negative pressure fan 170.

In this embodiment, as shown in FIG. 1, the height of the first space 111 is lower than the height of the second space 112, and the height of the demolding water recovery tank 140 is lower than the height of the second space 112. The demolding water spray inlet 120 is provided at the top of the first space 111, and the suction hood 140 is provided on the side wall of the first space 111 away from the second space 112. When the negative pressure fan 170 causes the first space 111 to form a negative pressure airflow, the atomized demolding water sprayed by the spray system of the die casting machine enters the first space 111 through the demolding water spray inlet 120 from above the first space 111. At the same time, The first space 111 inhales air through the suction hood 140 provided on the side wall away from the second space 112 to ensure that the atomized demolding water sucked into the first space 111 flows to the demolding water recovery tank 140 and The second space 112 where it is located.

As shown in FIG. 1, the self-excited tapping device 150 includes a self-excited plate 151 and a tapping plate 152; the self-excited plate 151 is an elastic bending plate, and one end of the self-excited plate 151 is horizontally fixed on the stripping water recovery tank 140 adjacent to the first On one side wall of the space 111, the other end of the self-excited plate 151 is inserted obliquely into the liquid level of the demolding water recovery tank 140.

When the negative pressure fan 170 causes the second space 112 to form a negative pressure airflow, it will automatically arouse the self-excited plate 151 and drive the flapping plate 152, so that the two will continuously beat the liquid surface of the demoulding water recovery tank 140 to arouse The water curtain splashes, so that part of the demolding water in the demolding water recovery tank 140 is sucked up.

As shown in FIG. 1, the counter-mixing device 160 includes a first rotating component 161 and a second rotating component 162.

That is, for those skilled in the art, according to actual needs, the counter-washing and stirring device 160 can be realized through different rotating structures. When part of the demolding water in the demolding water recovery tank 140 is sucked up, the mixed demolding water and air flow will first encounter the first rotating assembly 161 and drive the first drum or the first wind wheel or the first vortex. The fan rotates to further agitate and fuse the mixed demolding water. At this time, part of the mixed water will be further stopped; the other part of the mixed water that continues to flow will meet the second rotating assembly 162 again, due to the arc-shaped rollers or arcs of the two The arc direction of the arc-shaped fan blade or arc-shaped fan blade is set in opposite directions, that is, the rotation direction of the two is just opposite, so that a relatively closed space will be formed between the two, and the mixed water will be pushed back and forth by the two rotating components. Thus, the mixing and fusion are fully carried out in this space, and finally, the various components in the mixed demolding water are fused and reduced in the hedging and stirring device 160, and then settled back into the demolding water recovery tank 140.

When the negative pressure fan in the third space works, due to the first space and the second space , The third space is connected in sequence, which can form a negative pressure air flow in the entire internal space of the main body of the ready-to-use device. The negative pressure air flow can inhale air from the first space and suck in the mold release water spray to be processed (die casting machine spray The atomized demolding water sprayed by the system), and the self-excited flapping device is automatically activated in the second space to arouse water splashes on the liquid surface of the demolding water recovery tank. In this way, part of the inhaled demolding water mist is blocked and fused by the pre-stored demolding water curtain in the demolding water recovery box, and the other part of the demolding water mist is mixed with the demolding water in the demolding water recovery box that comes with it. The water flows upward along with the suction generated by the negative pressure airflow. When it passes through the counter-mixing device, it can be fully stirred and fused in this space and then settled back into the mold release water recovery tank. Finally, the mold release water recovery tank is fully stirred and fused.
