[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0043] In this embodiment of the utility model, please refer to Figures 1 to 3 A CNC machining center oil mist purification device includes a purification chamber 1, an air outlet pipe 4 at the top of the purification chamber 1, and an oil mist outlet at the bottom of the purification chamber 1.

[0046] Cover plate 6 is hinged to cleanroom 1 via a hinge;

[0047] The oil mist purification unit, located inside the purification chamber 1, is used to separate and remove oil mist;

[0048] Cover plate 2 7 is hinged to cleanroom 1 and is located at the top of cover plate 1 6;

[0049] The fixed plate 10 is connected to the inner wall of the cleanroom 1 and is located at the top of the oil mist purification mechanism;

[0050] HEPA filter 11 is snapped into the fixing plate 10;

[0051] The activated carbon plate 12 is snapped into the fixing plate 10 and is located on top of the HEPA filter 11;

[0052] The airflow disturbance mechanism is connected to the cleanroom 1 at one end and to the oil mist purification mechanism at the other end. It is located between the oil mist purification mechanism and the HEPA filter 11 and is used to disturb the airflow.

[0053] The transverse reciprocating mechanism is connected at one end to the oil mist purification mechanism and at the other end to the sliding plate 2, and is used to drive the sliding plate 2 to reciprocate laterally.

[0054] Oil mist generated by the CNC machining center enters the purification chamber 1 through the mist inlet pipe 3. The transverse reciprocating mechanism drives the sliding plate 2 to reciprocate laterally, which in turn drives the mist inlet pipe 3 to reciprocate laterally, optimizing the air intake direction and flow rate, so that the oil mist is evenly distributed. The oil mist purification mechanism separates and removes the oil mist, and the turbulence mechanism disturbs the airflow, so that the airflow is in full contact with the HEPA filter 11 and the activated carbon plate 12. The HEPA filter 11 filters out fine particles in the oil mist, and the activated carbon plate 12 adsorbs odors and harmful substances in the oil mist. The purified gas flows out from the exhaust pipe 4. When the HEPA filter 11 and the activated carbon plate 12 need to be replaced, the cover plate 2 7 is opened, and the HEPA filter 11 and the activated carbon plate 12 are removed for cleaning and replacement.

[0060] The oil mist remover 9 removes oil mist from the gas. A motor (not shown in the diagram) drives the striking rod 14 to rotate, causing it to continuously strike the sliding plate 8. Under the reaction force of the elastic element 13, the oil mist remover 9 moves up and down continuously, facilitating the dripping of oil mist adhering to it. When the oil mist remover 9 needs cleaning or replacement, simply open the cover plate 6 to remove it. The elastic element 13 can be a spring, sheet metal, or similar material.

[0066] The spiral spring 19 is connected at one end to the fixed rod 17 and at the other end to the rotating plate 18.

[0067] The motor drives the rotating disk 15 to rotate via belt 16, which in turn drives the fixed rod 17 and the rotating plate 18 to revolve around the central axis of the rotating disk 15. During this process, the rotating plate 18 rotates around the fixed rod 17, and the angle of the rotating plate 18 changes, thereby disturbing the airflow and improving the purification efficiency.

[0068] As one embodiment of this utility model, please refer to Figure 1 and Figure 2 The lateral reciprocating mechanism includes:

[0071] Gear 22 is missing; it is rotatably connected to the cleanroom 1 and to the other end of belt 21.

[0072] The toothed plate 23 is connected to the sliding plate 2 and meshes with the upper gear teeth of the missing gear 22.

[0073] The motor rotates via belt 21, which in turn drives the gear 22 to rotate. The teeth of the gear 22 mesh with the toothed plate 23, causing the toothed plate 23 to move to one side. The toothed plate 23 then drives the sliding plate 2 to move to one side, which in turn drives the mist inlet pipe 3 to move to one side. The elastic element 20 undergoes elastic deformation. When the teeth of the gear 22 rotate to the point of disengaging from the toothed plate 23, the reaction force of the elastic element 20 causes the sliding plate 2 to drive the mist inlet pipe 3 to move in the opposite direction, realizing the lateral reciprocating motion of the mist inlet pipe 3, optimizing the air intake direction and flow rate, and ensuring uniform distribution of oil mist. The elastic element 20 can be a spring, sheet metal, etc.

[0076] The purified gas is discharged from the outlet pipe 4 under the action of the fan 5, completing the entire purification process.

[0077] The working principle of this utility model is as follows: Oil mist generated by the CNC machining center enters the purification chamber 1 through the mist inlet pipe 3. The motor rotates via belt 21, which drives the gear 22 to rotate. The upper gear teeth of the gear 22 mesh with the gear plate 23, causing the gear plate 23 to move to one side. The gear plate 23 then drives the sliding plate 2 to move to one side, which in turn drives the mist inlet pipe 3 to move to one side. The elastic element 20 undergoes elastic deformation. When the upper gear teeth of the gear 22 rotate to disengage from the gear plate 23, the reaction force of the elastic element 20 causes the sliding plate 2 to drive the mist inlet pipe 3 to move in the opposite direction, realizing the lateral reciprocating motion of the mist inlet pipe 3, optimizing the air intake direction and flow rate, and ensuring uniform distribution of oil mist. The oil mist removal screen 9 removes the oil mist from the gas. The motor... The striking rod 14 is rotated, causing it to continuously strike the sliding plate 8. Under the reaction force of the elastic element 13, the oil mist removal screen 9 moves up and down continuously, facilitating the dripping of oil mist adhering to the screen. The motor drives the rotating disk 15 to rotate via the belt 16, causing the fixed rod 17 and the rotating plate 18 to revolve around the central axis of the rotating disk 15. During this process, the rotating plate 18 rotates around the fixed rod 17, and the angle of the rotating plate 18 changes, thereby disturbing the airflow and ensuring that the airflow fully contacts the HEPA filter 11 and the activated carbon plate 12. The HEPA filter 11 filters out fine particles in the oil mist, and the activated carbon plate 12 adsorbs odors and harmful substances in the oil mist. The purified gas flows out from the outlet pipe 4.
