[0007] Preferably, the other end of the ventilation main pipe away from the connecting pipe is fixedly connected to a positive pressure fan.

[0008] By adopting the above technical solution, the positive pressure fan at one end of the ventilation main blows the debris to the collection device at the other end, and the negative pressure fan sucks the debris in the main into the collection device. At the same time, the positive pressure fan at the end of the ventilation main blows the debris to the collection device, thereby improving work efficiency. The fans running at both ends of the ventilation main increase the air flow rate inside the ventilation main, reduce the atmospheric pressure above the branch pipe, and reduce the resistance of the debris rising into the ventilation main.

[0009] Preferably, a filter element is fixedly connected to the air outlet of the negative pressure fan connected to the main pipe.

[0010] The above technical solution is adopted to prevent the negative pressure fan from sucking metal debris onto its fan blades.

[0021] The following description is merely a preferred embodiment of the present invention, and the scope of protection is not limited to this embodiment. All technical solutions based on the principles of the present invention should be included in the scope of protection of the present invention. It should also be noted that improvements and modifications that do not depart from the principles of the present invention by ordinary skill in the art should also be considered within the scope of protection of the present invention.

[0022] See Figure 1 、 Figure 2 and Figure 3A chip removal mechanism for a grinder is provided with a grinder 1, a ventilation main 2 and a collection device 3. There are multiple grinders 1, and the grinder 1 is located in a production workshop. The collection device 3 is located on the side of the end grinder 1. The workshop wall is fixedly connected with a support frame 4 by expansion bolts. The ventilation main 2 is fixedly connected to the support frame 4 horizontally, and the ventilation main 2 is horizontally above the grinder 1. A plurality of vertical branch pipes 5 are connected below the ventilation main 2, and each branch pipe 5 corresponds to each grinder 1 respectively. The branch pipe 5 above the grinder 1 is narrow at the top and wide at the bottom, so that the chips can be better introduced. Into the branch pipe 5, and each branch pipe 5 is provided with a valve 11, which is used to close the valve 11 of its upper branch pipe 5 when a certain grinder 1 is not working, so as to stop the upper branch pipe 5 from sucking in debris. A negative pressure fan 6 is fixedly connected to the middle part of the upper part of the ventilation main pipe 2, and a filter element 10 is fixedly connected to the air outlet where the negative pressure fan 6 is connected to the main pipe. One end of the ventilation main pipe 2 is connected to a vertically downward connecting pipe 9, and the other end of the connecting pipe 9 is connected to the collecting device 3, which is fixedly connected to the negative pressure fan 2 7. The other end of the ventilation main pipe 2 away from the connecting pipe 9 is fixedly connected to the positive pressure fan 8.

[0023] Working principle: When working, open the valve 11 of the upper branch pipe 5 of the grinder 1, and the negative pressure fan 6 sucks the metal debris generated by the grinder 1 from the branch pipe 5 into the ventilation main pipe 2. The air outlet of the negative pressure fan 6 is provided with a filter element 10. The debris is blocked by the filter element 10 and the debris will not be sucked onto the fan blades of the negative pressure fan 6. The positive pressure fan 8 at one end of the ventilation main pipe 2 blows the debris to the collection device 3 at the other end. At the same time, the negative pressure fan 2 7 on the collection device 3 also sucks the debris into the collection device 3 for storage. The fans at both ends of the ventilation main pipe 2 increase the air flow rate in the main pipe, reduce the atmospheric pressure at the top of the branch pipe 5, and reduce the resistance of the debris rising into the ventilation main pipe 2, so that the debris can enter the ventilation main pipe 2 more easily, reducing the content of debris in the air, thereby reducing the impact on human health and the environment.
