[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] Example 1

[0028] Reference Figure 1-5 , an oil mist collector, which is used in the field of machine tool processing technology, including:

[0029] It includes a collector shell 1, one side of which is fixedly installed with an air inlet pipe 4 for introducing a mixed gas containing oil mist. Inside the collector shell 1, a first-level pre-filter plate 5, a second-level filter screen 6 and a third-level oil mist filter cotton 7 are arranged in sequence according to the air flow direction. These filter elements filter the incoming mixed gas step by step to remove impurities and oil mist therein.

[0030] Inside the collector housing 1, a high-efficiency motor 9 is fixedly installed via a mounting frame, and one end of the output shaft of the motor is connected to a centrifugal separator 8; when the motor is working, the centrifugal separator 8 will centrifugally separate the oil mist in the mixed gas and separate the oil mist from the gas.

[0031] On the side of the collector housing 1 away from the air inlet pipe 4, a flow equalizing box 11 is fixedly installed. The flow equalizing box 11 is connected to the interior of the collector housing 1. A safety filter 12 is fixedly installed on the other end of the flow equalizing box 11. The safety filter 12 serves as the last filtering barrier to ensure that the exhausted gas reaches a certain degree of cleanliness and prevents external impurities from entering the interior of the collector.

[0032] In order to introduce the mixed gas from the discharge device into the collector, a gas pipe 2 is provided in this embodiment, one end of the gas pipe 2 is connected to the air inlet pipe 4, and the other end is connected to the exhaust port of the mixed gas discharge device to complete the transportation of the mixed gas.

[0033] In order to realize the quick connection between the air supply pipe 2 and the air intake pipe 4, a fixing assembly is designed in the present embodiment; the fixing assembly includes a fixing device 14 rotatably sleeved on the outer wall of the air supply pipe 2, the fixing device 14 is composed of a rotating collar 15 and two first arc-shaped blocks 16, the two first arc-shaped blocks 16 are fixedly mounted on the outer wall of the rotating collar 15, the rotating collar 15 is rotatably sleeved on the outer wall of the air supply pipe 2, so that the fixing device 14 can rotate around the air supply pipe 2; a fixing ring 13 is fixedly mounted on one end of the flange of the air intake pipe 4, two second arc-shaped blocks 17 are fixedly mounted on the inner wall of the fixing ring 13, the outer parts of the two first arc-shaped blocks 16 and the two second arc-shaped blocks 17 are both provided with a soft rubber material layer, which is used for In order to improve the contact effect when the two are engaged, the friction force when they are in contact can also be increased, and they will not rotate at will when engaged. When the gas pipe 2 and the air inlet pipe 4 need to be connected, first insert one end of the gas pipe 2 into the air inlet pipe 4, so that the two first arc-shaped blocks 16 pass through the gap between the two second arc-shaped blocks 17, and then rotate the fixer 14 to make the two first arc-shaped blocks 16 and the two second arc-shaped blocks 17 engage with each other, thereby completing the connection and fixation of the gas pipe 2 and the air inlet pipe 4. In order to ensure the sealing of the connection, a sealing ring 18 is also fixedly sleeved on the outer wall of the rotating ring 15. After the fixation of the fixer 14 is completed, the sealing ring 18 is tightly matched with one end of the fixing ring 13 to effectively prevent gas leakage.

[0034] A collecting chamber 10 is also provided inside the collector housing 1. The collecting chamber 10 is located below the centrifugal separator 8, and its opening corresponds to the centrifugal separator 8. When the centrifugal separator 8 is working, the oil in the oil mist will be separated. The oil is collected through the collecting chamber 10. In order to facilitate the discharge of the collected oil, a first oil drain pipe 3 is fixedly connected to one side of the collecting chamber 10; at the same time, a second oil drain pipe is also fixedly connected to the bottom of the collector housing 1, and one end of the second oil drain pipe cooperates with the three-stage oil mist filter cotton 7 to discharge the filtered oil.

[0035] Example 2

[0036] Reference Figure 2 , 4 5. Improvements based on Example 1:

[0037] In this embodiment, the two first arc-shaped blocks 16 and the two second arc-shaped blocks 17 are arranged opposite to each other, and the minimum straight-line distance between the two second arc-shaped blocks 17 is greater than the horizontal projection length of the two first arc-shaped blocks 16. This design ensures that when the two first arc-shaped blocks 16 are staggered with the two second arc-shaped blocks 17, the two first arc-shaped blocks 16 can pass through the gap between the two second arc-shaped blocks 17, thereby realizing a quick connection between the air supply pipe 2 and the air intake pipe 4.

[0038] In addition, one end of the gas pipe 2 passes through the holder 14 and extends into the interior of the air intake pipe 4, and the outer wall of the gas pipe 2 fits tightly with the inner wall of the air intake pipe 4 to ensure good delivery of the mixed gas and reduce the possibility of gas leakage.

[0039] In order to facilitate the user to operate the holder 14, a plurality of levers 19 are fixedly mounted on the outer wall of the sealing ring 18. These levers 19 provide force application points for rotating the holder 14; in particular, the length and radius of the two levers 19 corresponding to the two first arc-shaped blocks 16 are greater than those of the other levers 19. This design allows the user to more intuitively observe the position of the first arc-shaped blocks 16 through the two longer levers 19, thereby more accurately completing the connection operation between the air delivery pipe 2 and the air intake pipe 4.

[0040] However, as is well known to those skilled in the art, the working principle and wiring method of the high-efficiency motor 9 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any selection according to their needs or convenience.

[0041] The working principle and use process of the technical solution are as follows: when in use, the collector is installed on the top of the gas exhaust device, or the collector is installed at a position close to the gas exhaust device using a bracket, and then the collector is connected to the gas exhaust device using the gas pipe 2; when connecting the gas pipe 2 to the collector, one end of the gas pipe 2 equipped with the fixer 14 needs to be inserted into the air inlet pipe 4, and then the user can rotate the fixer 14 to stagger the two first arc-shaped blocks 16 with the two second arc-shaped blocks 17 inside the fixing ring 13, and then as the gas pipe 2 goes deeper, the two first arc-shaped blocks 16 enter the fixing ring 13 Then, the fixer 14 is rotated again to make the two first arc-shaped blocks 16 snap into the gap between the two second arc-shaped blocks 17 and the fixing ring 13, and the installation of the fixer 14 is completed, thereby completing the connection and fixation of the air supply pipe 2 and the air intake pipe 4; the outsides of the two first arc-shaped blocks 16 and the second arc-shaped blocks 17 are both provided with a soft rubber material layer, which can ensure that the friction force of the first arc-shaped blocks 16 and the second arc-shaped blocks 17 when they are engaged is large, and when the fixer 14 is installed, one side of the sealing ring 18 will be close to the fixing ring 13, which can ensure that the air supply pipe 2 and the air intake pipe 4 are well sealed during installation, and can ensure good subsequent air supply effect;

[0042] After the mixed gas begins to be transported, the mixed gas containing oil mist, water vapor, dust, etc. will quickly enter the primary separation area through the intake pipe 4 and contact the primary pre-filter plate 5. Due to the inertia principle, larger oil droplets and water vapor will collide with the end surface of the primary pre-filter plate 5 and flow downward, while the bundled gas will be separated by the numerous pores of the primary pre-filter plate 5. The separated gas enters the secondary interception filter area;

[0043] In the secondary interception filtration area, the beam-like airflow is uniformly circulated in a nearly horizontal direction, and passes through the secondary outlet filter screen 6 and the tertiary oil mist filter cotton 7 to complete the secondary filtration. The tertiary oil mist filter cotton 7 is made of synthetic fibers with gradually increasing density, which can effectively filter particles with a diameter of ≥5μm. Through interception filtration, the fine liquid particles in the airflow rapidly condense into larger oil droplets, which are discharged from the bottom to the bottom of the filter box and flow downward in the vertical direction.

[0044] Afterwards, the exhausted gas is gathered into a bundle again and enters the high-speed rotating impeller. The gas in the impeller is compressed again and generates acceleration along the radial direction of the blade, forming a high-speed centrifugal force. Due to the different ratios of gas, liquid and solid, some fine oil mist particles and finer aerosol particles in the gas under the action of centrifugal force are thrown to the sedimentation separator along the blade diameter direction. The sedimentation separator contains a compartment. It is difficult for the oil particles to flow out again after entering the compartment to mix with the airflow, and they condense and settle downward. The gas is pushed backward along the horizontal direction of the impeller, and the gas and liquid are separated again.

[0045] The oil mist ratio of the treated oil mist gas is reduced to the minimum value, and the residual gas is intercepted, diffused and rectified by the safety filter 12 to complete the discharge of clean gas.

[0046] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
