Description

Technical Field

[0001] The invention relates to the technical field of numerical control machining centers, in particular to a cooling liquid recovery and processing device for numerical control machining centers. Background Art

[0002] CNC machining centers are indispensable processing equipment in the current mechanical parts processing process. Various precision data processing is completed through CNC machining centers. During the processing, CNC machining centers will generate high heat due to processing. In order to prevent internal overheating and high temperature, the processing position needs to be cooled. The commonly used method is to use coolant to cool the processing position. The coolant needs to be recycled after spraying so that it can be used for cooling next time to prevent coolant waste. Therefore, there is a coolant recovery and processing device in the CNC machining center.

[0003] The existing referenceable Chinese invention patent has a grant announcement number of CN211890025U, which discloses a coolant recovery device for a CNC machining center. The coolant recovery device for a CNC machining center is provided with a filter cartridge, and the coolant is preliminarily filtered through a first filter screen, and the first filter screen can be removed from the filter cartridge, which is convenient for the user to clean or replace it. A multi-stage filter plate is provided to perform multiple filtrations on the coolant, and the filter plate can be pulled out of the filter box, which is convenient for the user to clean or replace it. In addition, the present invention provides a first magnetic rod and a second magnetic rod to adsorb iron filings in the coolant, so that the coolant is restored to a clean state; the present invention provides a heat pipe, a heat sink and a cooling fan, so that the coolant can be cooled quickly and can be put into use again as soon as possible.

[0004] However, the current CNC machining center coolant recovery and processing equipment has poor overall heat dissipation efficiency when cooling and dissipating the coolant. It is not possible to cool and dissipate the coolant simultaneously during the recovery process and the flow of the liquid. Instead, it adopts a centralized cooling and heat dissipation process after all the recovery is completed. In this way, the cooling speed of the coolant is affected by the volume capacity, resulting in a slowdown in the cooling speed and efficiency, which affects the timely recovery of the coolant. Summary of the Invention

[0005] The purpose of the present invention is to overcome the technical problem of slow cooling speed in the prior art, which affects the efficiency of coolant recovery circulation, and provide a coolant recovery and processing device for a CNC machining center. The coolant recovery and processing device for a CNC machining center has the advantages of being able to complete cooling and heat dissipation treatment during the flow of coolant, thereby improving the subsequent cooling speed and improving the recovery efficiency.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A coolant recovery and processing device for a CNC machining center, comprising:

[0008] A recycling box, wherein heat dissipation fins are installed on the outside of the recycling box, and a filter plate for filtering iron filings is embedded and installed on the top of the recycling box, a channel is threadedly connected to the bottom of the recycling box, and the lower end of the channel is connected to the collection box, and a middle barrel is installed inside the collection box, a conical seat is installed inside the middle barrel, and a cooling fan for heat dissipation is installed in the hollow bottom of the conical seat, a heat dissipation outlet is provided on the outer edge surface of the upper end of the middle barrel, a heat sink is installed inside the channel, and a receiving tube is installed above the heat sink.

[0016] Preferably, the collection box further comprises:

[0022] 1. This coolant recovery and processing device for CNC machining centers has a highly integrated structure. By setting up heat sinks and discharge pipes inside the channel, the recovered coolant is diverted by the discharge pipe, reducing the flow volume of the coolant, which is conducive to improving the heat dissipation speed of the coolant. Secondly, the spiral blades set in the discharge pipe and the heat sinks set inside the channel are conducive to increasing the contact area between the coolant and the air, improving the heat dissipation speed and efficiency, and allowing the coolant to effectively dissipate heat during the flow recovery process;

[0023] 2. The coolant recovery and processing device for the CNC machining center installs a middle barrel inside the collection box, which is used to divide the interior of the collection box and the coolant. Before the coolant flows into the inner bottom of the collection box, it first passes through the middle barrel. The cooling fan inside the middle barrel is used to further cool the coolant. In conjunction with the conical seat and bucket plate, the heat in the coolant is fully evaporated, increasing the contact area with the air and accelerating the heat dissipation. Finally, the coolant flows into the interior of the collection box, thereby improving the quality of heat dissipation and the recovery efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0031] Combined with attachment Figure 1-5 In this embodiment, a coolant recovery and processing device for a CNC machining center includes a recovery tank 1, with heat dissipation fins 2 mounted on the outside of the recovery tank 1, and a filter plate 3 for filtering iron filings mounted above the recovery tank 1. A channel 4 is threadedly connected to the bottom of the recovery tank 1, and the lower end of the channel 4 is connected to a collection tank 5. A heat dissipation fin 401 is mounted inside the channel 4, and a receiving tube 402 is mounted above the heat dissipation fin 401. The front side of the collection tank 5 is connected to a transition tank 6 via a pipe, and a recovery pipe 7 is connected to one side of the transition tank 6. A valve 8 for control is mounted on the surface of the recovery pipe 7.

[0032] Specifically, the recovery box 1 serves as the installation reference of the entire device, and undertakes the role of structural connection and integration. The outer wall of the recovery box 1 is installed with heat dissipation fins 2, which can dissipate heat for the coolant flowing and recovered in the recovery box 1. After recovery by the recovery box 1, the coolant is collected into the interior of the collection box 5 through the channel 4. The interior of the channel 4 is also provided with heat dissipation fins 401 for auxiliary heat dissipation, and the coolant in the collection box 5 is recovered into the coolant tank through the pipeline.

[0033] To facilitate those skilled in the art to fully understand the specific structure and principle of the receiving tube 402, the receiving tube 402 is further described. In this embodiment, the receiving tube 402 includes: a discharge pipe 403, which is connected to the lower surface of the receiving tube 402 and is interconnected with the interior of the receiving tube 402; a center column 404, which is installed at the center of the discharge tube 403 and has a spiral plate 405 on its surface; a hydraulic rod 406, which is disposed at the upper end of the spiral plate 405, and the output end of the hydraulic rod 406 is interconnected with the upper end of the spiral plate 405; and a flat outlet 407, which is connected to the lower end outlet of the discharge tube 403. The spiral plate 405 is arranged in a spiral shape with respect to the surface of the center column 404, and the discharge tube 403 is arranged in a ring shape with respect to the center line of the receiving tube 402.

[0034] In the receiving tube 402, a discharge pipe 403 for discharging the coolant is provided. By using the several discharge pipes 403, the coolant can be diverted and the heat can be dissipated, which helps to quickly dissipate the heat of the coolant. The flat outlet 407 at the lower end of the discharge pipe 403 is aligned with the heat sink 401 inside the channel 4, so that the coolant can pass through the channel 4 smoothly.

[0035] To facilitate those skilled in the art to fully understand the specific structure and principle of the collection box 5, the collection box 5 is further described. In this embodiment, the collection box 5 is installed with a middle barrel 51, and a conical seat 52 is installed inside the middle barrel 51. A cooling fan 57 for heat dissipation is installed in the hollow bottom of the conical seat 52. A heat dissipation vent 58 is provided on the outer edge surface of the upper end of the middle barrel 51. The collection box 5 also includes: a hopper tray 53, which is arranged below the conical seat 52 and has a through pipe 54 connected to the bottom of the hopper tray 53; and a discharge tray 55, which is integrally connected to the lower end of the middle barrel 51, and an outlet 56 for communication is provided at the junction of the discharge tray 55 and the middle barrel 51.

[0036] The outer shape of the bucket plate 53 is an inverted cone structure, and the distance between the upper surface horizontal plane of the bucket plate 53 and the lower surface of the conical seat 52 is 8-10 cm.

[0037] In the collecting box 5, a conical seat 52 for downward drainage is provided, and an inverted conical bucket plate 53 is located below the conical seat 52, so that the coolant drained downward can enter the bucket plate 53, and opposite the center of the bucket plate 53 is a cooling fan 57 located at the bottom center of the conical seat 52. The cooling fan 57 helps to dissipate heat, and finally flows to the bottom of the middle barrel 51 through the through pipe 54.

[0038] To facilitate those skilled in the art to fully understand the specific structure and principle of channel 4, a further description of channel 4 is provided. In this embodiment, the outer diameter of the lower end of channel 4 matches the inner diameter of the upper opening of the middle barrel 51, and channel 4 passes through the upper end of the middle barrel 51 to the interior of the upper end of the middle barrel 51.

[0039] By docking the channel 4 with the middle barrel 51, the lower end of the channel 4 penetrates into the upper end of the middle barrel 51, so that the coolant can approach the conical seat 52 and flow downward along the surface of the conical seat 52. The conical seat 52 is used to increase the area where the coolant flows, thereby accelerating heat dissipation.

[0040] Working principle: First, the coolant will pass through the filter plate 3 above the recovery box 1 and enter the interior of the recovery box 1. The heated coolant enters the recovery box 1, and the heat will be conducted to the outer wall of the recovery box 1 and dissipated through the heat dissipation fins 2. After passing through the recovery box 1, the coolant will flow downward and enter the receiving tube 402 inside the channel 4, and flow into the discharge pipe 403 connected to the bottom of the receiving tube 402. The hydraulic rod 406 is used to pull the spiral piece 405 up and down so that the coolant can fully contact the spiral piece 405, increase the contact area, and accelerate the heat dissipation. Then the squeezed coolant will contact the heat sink 401 below, and after contacting the heat sink 401, it will enter the internal barrel 51 of the collection box 5 below the channel 4, and flow along the upper end of the inner barrel 51. The conical seat 52 guides the flow downward. During the flow, the coolant will be spread on the surface of the conical seat 52 and flow downward into the bucket plate 53. The inverted conical bucket plate 53 is used to allow the coolant to accumulate in the center of the bucket plate 53. The cooling fan 57 directly above will blow air to dissipate heat. The hot air will be discharged along the gap between the bucket plate 53 and the conical seat 52, and discharged from the interior of the middle barrel 51 through the heat dissipation vent 58. Finally, it flows to the bottom of the middle barrel 51 through the through pipe 54 connected to the lower end of the bucket plate 53, and then discharged from the interior of the middle barrel 51 through the outlet 56, and discharged into the interior of the collection box 5 along the discharge plate 55. Finally, it enters the transition box 6 through the pipeline, and then uses the recovery pipe 7 and valve 8 to recover the coolant back to the coolant tank for the next cooling use.

[0041] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
