This creation is about the backstop structure of an oil mist recovery air cleaner, especially when the oil mist recovery air cleaner is stopped, the oil mist recovery air cleaner that can prevent the oil mist on the processing equipment from continuing to flow to the inside of the machine body Backstop structure.

Press; In the general processing equipment, in order to prevent the high temperature caused by the contact between the workpiece and the tool during the processing operation, the temperature of the workpiece and the tool is usually reduced by adding cutting oil. Although this kind of cooling method has been used in the industry for a long time, the addition of cutting oil will cause the entire workplace to be filled with oil mist. Therefore, relevant industries have developed an oil mist recovery machine to reduce and recover air. Oil mist to improve air quality in the workplace. The conventional oil mist recovery machine is provided with a body, and a rotatable filter screen and an exhaust device are provided in the body, and an air inlet and an air outlet are respectively provided at the front edge and above, and a filter material is provided at the air outlet . After starting the air extraction device to allow the oil and gas to enter the body from the air inlet, the oil and gas rotates at a high speed through the filter to generate centrifugal force, and the oil and water are initially intercepted and separated, and then the oil and gas is guided from the air outlet to the air outlet The filter material filters again and allows clean air to be discharged to the outside world.

However, when the oil mist recovery machine is stopped, the oil mist at the end of the processing tool may continue to flow inside the machine body, causing the oil mist recovery machine to be damaged due to prolonged humidity. In view of this, after continuous research and experiments, the applicant has designed a backstop structure for an oil mist recovery air cleaner, which can prevent the oil mist of the processing equipment from flowing into the body when the oil mist recovery machine is stopped.

The main purpose of this creation is to provide a backstop structure for the oil mist recovery air cleaner. When the oil mist recovery air cleaner is stopped, it can prevent the oil mist from flowing back into the body and the processing equipment, thereby preventing the body and processing.
