Description

Technical Field

[0001] The invention belongs to the technical field of wastewater treatment, and specifically discloses a wastewater treatment device for a numerically controlled machine tool. Background Art

[0002] When CNC machine tools process mechanical parts, wastewater will be generated inside the CNC machine tools. The wastewater is usually a mixture of cooling water and iron filings. In order to avoid damage to the machine tools caused by the wastewater inside the machine tools, the staff needs to discharge the wastewater in time. At this time, the wastewater treatment device needs to be used; A traditional wastewater treatment device usually has a fixed pipe connected to the drainage end of a machine tool. The pipe can drain the wastewater inside the machine tool to a wastewater collection chamber, and then the filter inside the wastewater collection chamber can filter the iron filings in the wastewater. The filtered wastewater can continue to cool down the mechanical parts. This type of wastewater treatment device can indeed achieve a good treatment effect on the wastewater, but when the wastewater collection chamber filters the wastewater through the filter, the wastewater treatment method is relatively conventional. There are multiple filter plates distributed at equal intervals inside the wastewater collection chamber. When used, the multiple filter plates distributed at equal intervals can indeed achieve a good filtering effect on the wastewater, but the wastewater is easily embedded between every two filter plates. The wastewater collection chamber is not provided with an iron filing processing structure. When the iron filings are embedded between the two filter plates, the iron filings will block the filter holes of the filter plate. At the same time, the wastewater collection chamber is not provided with a structure for discharging iron filings, which will lead to a decrease in the efficiency of the filter plate in filtering wastewater.

The wastewater discharged from the discharge box 1 can be transported to the drainage pipe 4 through the discharge pipe 2. At the same time, the wastewater can be filtered through the guide part 9 and the filter holes 10 on the drainage pipe 4. When the wastewater is filtered through the filter holes 10, the powder filtered by the wastewater can enter the interior of the collection chamber 6. At the same time, the wastewater filtered by the filter holes 10 can flow back to the interior of the discharge pipe 2, so that the discharge pipe 2 drives the wastewater to be discharged. When the powder falls on the filter boss 24, the staff will start the transmission motor 7 through the controller 39.
