[0029] Example 1

[0030] Ginseng Figures 1 to 3 As shown, this embodiment discloses a specific implementation of a two-stage chip collection and exhaust gas purification device for a copper belt milling machine.

[0031] A two-stage chip collection and exhaust gas purification device for a copper belt milling machine, Figures 1 to 3As shown, it includes several groups of waste chip recovery systems. In this embodiment, the front milling cavity 1, the back milling cavity 2 and the side milling cavity 3 respectively mill the front, back and sides of the copper strip. The waste chip recovery system is arranged in three groups, wherein the first group of waste chip recovery systems recovers the waste chips of the front milling cavity 1, the second group of waste chip recovery systems recovers the waste chips of the back milling cavity 2, and the third group of waste chip recovery systems recovers the waste chips of the side milling cavity 3; the first group of waste chip recovery systems is taken as an example for detailed description below, the waste chip recovery system includes a primary cyclone separation component 4, a secondary cyclone separation component 5 and a fan 6; the primary cyclone separation component 4 sucks the waste chips from the front milling cavity 1 of the milling machine through the first suction pipe 41, the sucked waste chips contain copper chips, emulsion and air, the primary cyclone separation component 4 separates most of the copper chips and emulsion, and after separation, they fall into the centrifuge 42 arranged below the primary cyclone separation component 4, and after being dried by the centrifuge 42, the waste chips are effectively The copper chips and the emulsion are separated. The surface of the recovered copper chips contains very little emulsion and can be directly used for reuse smelting. The secondary cyclone separation component 5 draws the first exhaust gas from the top of the primary cyclone separation component 4 through the second suction pipe 51. The first exhaust gas is mainly air, but contains a small amount of emulsion and a small amount of copper chips. The secondary cyclone separation component 5 further separates the small amount of copper chips, and the separated copper chips fall into the chip leakage port 52 set below the secondary cyclone separation component 5. The chip leakage port 52 is a detachable chip leakage port. Since the secondary cyclone separation component 5 separates less copper chips, the chip leakage port 52 can be opened at intervals to clean the waste chips; the fan 6 draws the second exhaust gas from the top of the secondary cyclone separation component 5 through the third suction pipe 61. The second exhaust gas contains a small amount of emulsion. The grease component in the emulsion needs to be purified before being discharged to avoid polluting the atmosphere; a purification component 7 is set in the third suction pipe 61 to remove the emulsion component in the second exhaust gas, especially the grease component.

[0032] See also Figure 1 The working principle of the purification component 7 is as follows: one of the following two technical solutions can be adopted. The first technical solution is that the purification component 7 includes at least one filter 71, and the grease in the second exhaust gas is filtered through the filter 71 to avoid polluting the atmosphere; the second technical solution is that the purification component 7 includes at least one filter 71 and a high-voltage electrostatic oil remover 72, and the second exhaust gas passes through the filter 71 and the high-voltage electrostatic oil remover 72 successively. After the grease in the second exhaust gas is preliminarily filtered by the filter 71, it passes through the high-voltage electrostatic oil remover 72 to adsorb the grease on the dust collecting plate of the high-voltage electrostatic oil remover 72, and the collected oil droplets on the dust collecting plate fall into the waste liquid collection tank 73 set at the bottom of the purification component 7 to achieve grease filtering and separation to avoid polluting the atmosphere.

[0033] It should be further explained that a high-voltage electrostatic field of aluminum alloy is set in the high-voltage electrostatic oil remover 72. When the second exhaust gas enters the high-voltage electrostatic field, the oil and gas are ionized and the oil mist is charged under the action of the high-voltage electric field, and most of it is degraded and carbonized; a small number of tiny oil particles move toward the positive and negative dust collecting plates of the electric field under the action of the electric field force of the adsorption electric field and the airflow, and are collected on the dust collecting plates and flow to the waste liquid collection tank 73 under the action of their own gravity.

[0034] The second group of waste chip recovery systems recover waste chips from the reverse milling surface cavity 2, and the third group of waste chip recovery systems recover waste chips from the side milling surface cavity 3. In view of the same working principle as the first group of waste chip recovery systems, they will not be described in detail here.

[0035] Through this embodiment, the waste chips sucked out by the milling machine contain copper chips, emulsion and air. The first-stage cyclone separation component and the second-stage cyclone separation component form a two-stage separation component, so that all the copper chips are separated and most of the emulsion is also separated, and the separation is thorough; the emulsion remaining in the second exhaust gas, especially the grease component, is removed by the purification component arranged in the third suction pipe, avoiding pollution of the atmosphere.
