Description

Technical Field

[0001] The utility model belongs to the technical direction of numerical control machine tools, and specifically relates to a cooling sewage treatment device for numerical control machine tools. Background Art

[0002] CNC machine tool is the abbreviation of digital control machine tool. It is an automated machine tool equipped with a program control system. The control system can logically process programs specified by control codes or other symbolic instructions, decode them, and express them in coded numbers. The information carrier is input into the CNC device. After calculation and processing, the CNC device sends various control signals to control the movement of the machine tool and automatically process the parts according to the shape and size required by the drawing. During the milling process of the CNC machine tool, the cutting position needs to be cooled by a water spray device. The existing water spray device does not have a collection function, and the water will flow everywhere, resulting in a waste of water resources.

[0003] For example, Chinese patent announcement No. CN218485274U discloses a wastewater treatment device for cooling a CNC machine tool. When in use, a water spray seat sprays the processing area on the machine body to achieve the purpose of cooling. The wastewater mixed with debris after spraying flows into the wastewater diversion cavity, and flows into the collection box through the discharge pipe for separation and collection. The filter seat filters the debris in the wastewater, and adopts a drawer-type method to facilitate its disassembly and processing. When the machine body is not being processed, the fan and the heating tube are started. The heating tube is used to heat and dry the surrounding air. The fan generates wind force to blow out the heated gas, so that the hot air is blown out at the filter seat to achieve the drying effect. The debris filtered on it is dried to avoid the problem of stickiness due to water, which is convenient for dumping and discharging of the debris and improves the efficiency of its centralized collection.

[0004] However, the CNC machine tool cooling wastewater treatment device in the above application has a fixed water spraying position of the water spraying seat, and cannot follow the work of the processing tool to perform follow-up water spray cooling. In addition, the device is not equipped with a protective device. When spraying water, it may cause water to splash to the outside and wet the processing workshop. Therefore, there are certain limitations.

[0005] For this reason, we urgently need to provide a CNC machine tool cooling wastewater treatment device. Utility Model Content

The filter box is arranged inside the reflux pipe, the filter plate is fixedly connected to the bottom of the filter box, and the pull ring is fixedly connected to the front center of the filter box.

[0011] A further improvement is that a sliding groove is provided on the front side of the reflux pipe, and the filter box is slidably connected to the inside of the sliding groove.

The filter box is cleaned regularly to prevent impurities such as iron filings from clogging the filter holes on the filter plate and affecting the filtering effect. Filter holes are evenly penetrated on the upper surface of the filter plate to filter the water that flows back after flushing.

[0012] A further improvement is that reflux holes are opened through the front and rear sides of the upper surface of the operating table to discharge the sewage after washing the workpieces, and the reflux pipe is located below the two reflux holes to prevent water from overflowing to the outside.
