Description

Technical Field

[0001] The utility model relates to the technical field of oil mist treatment, in particular to a split drum type oil mist processor with simple structure, good oil mist separation effect, convenient maintenance and convenient discharge of separated oil. Background Technique

[0002] As is well known, during the processing of numerically controlled machine tools, a large amount of oil mist containing polychlorinated biphenyl components is generally generated, which implicitly damages the physical and mental health of workers. Inhaling particles with a size of 0.3 - 3.5 microns into the human body poses a hazard to health. The oil mist deposits in the working area, easily causing accidents such as work injuries. In addition, a large amount of oil mist generated by high-speed cutting adheres to the equipment and workpieces for a long time, which is likely to cause faults in the machine tool and the electrical system, bringing great trouble to the maintenance of the machine tool work and greatly reducing the machining precision of the machine tool. If the oil mist gas is directly discharged outdoors, it will damage the environment.

[0003] Currently, generally, an oil mist processor is used to completely separate air and oil, recycle the separated oil, and discharge the separated gas after treatment. The existing oil mist processors still have many deficiencies in actual use. Their structural design is unreasonable, equipment cleaning and maintenance are inconvenient, and the discharge of separated oil and gas is inconvenient. In particular, the oil outlet is generally located below the cylinder body and flows out by its own weight. However, due to the large suction force generated during the working state of the oil mist processor, sometimes the oil is sucked to the upper part of the shell, resulting in poor oil discharge effect. Moreover, the cylinder body is generally connected to the cylinder through a cover for fixing the motor, and its cleaning and maintenance effects are not good. Summary of the Invention

[0004] The purpose of the utility model is to solve the above-mentioned deficiencies of the prior art and provide a split drum type oil mist processor with simple structure, good oil mist separation effect, convenient maintenance and convenient discharge of separated oil.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A split drum type oil mist processor, characterized in that the processor comprises an upper cover body, a lower cylinder body, a motor, a rotating shaft, and a rotating separation cylinder. The upper end of the upper cover body is closed and provided with a groove. The middle of the groove of the upper cover body is fixedly connected with the motor. The output end of the motor extends into the upper cover body and is fixedly connected with the core shaft of the rotating separation cylinder. The rotating separation cylinder is provided with oil outlet sieve holes. The inner wall of the rotating separation cylinder body is fixedly connected with separation blades. The outside of the rotating separation cylinder is sleeved with a lower cylinder body. The upper cover body and the lower cylinder body are fixedly and hermetically connected by a buckle. The lower end of the lower cylinder body is provided with an oil mist inlet. The groove of the upper cover body is provided with an air outlet. The side surface of the upper end of the lower cylinder body is provided with an oil outlet, and the oil outlet is connected with an oil outlet pipe. The inner wall of the lower cylinder body is connected with a spiral blade. The lower end of the spiral blade extends straight to the lower end of the lower cylinder body, and the upper end of the spiral blade extends straight to the position of the oil outlet.

[0007] In the present utility model, the height of the upper cover body is the same as that of the lower cylinder body, or the height of the lower cylinder body is 0.5 - 2 times that of the upper cover body.

[0008] In the present utility model, the spiral blade is 0.8 - 1.5 spiral circumferences to ensure the oil drainage effect.

[0009] In the present utility model, the lower end of the upper cover body covers the outside of the upper end of the lower cylinder body. The lower end of the upper cover body is provided with a slot that matches the position of the oil outlet pipe. By means of the slot, it is ensured that while the upper cover body covers the lower cylinder body, the oil outlet pipe can also be clamped.

[0010] In the present utility model, the oil outlet sieve holes on the rotating separation cylinder body are distributed in blocks along the circumference of the rotating separation cylinder body. The part of the rotating separation cylinder body between each block of oil outlet sieve holes is a strengthening part. The separation blades are fixed at the strengthening part position, ensuring the separation effect and at the same time increasing the structural stability of the rotating separation cylinder body.

[0011] In the present utility model, the upper end of the rotating separation cylinder body is provided with a sealing plate fixedly connected with the core shaft. The sealing plate is in a stepped groove shape. The stepped groove-shaped sealing plate ensures the overall strength of the structure of the rotating separation cylinder body and at the same time can increase the rotational stability of the rotating separation cylinder body.

[0012] In the present utility model, the separation blades are in a bent shape. One end of the separation blade is fixedly connected with the rotating separation cylinder body, and the other end of the separation blade extends towards the center of the rotating separation cylinder body.

[0013] Due to the adoption of the above structure, the present utility model has the advantages of simple structure, good oil mist separation effect, convenient maintenance, and convenient discharge of the separated oil. Description of the Drawings

[0020] The present utility model will be further described below in conjunction with the accompanying drawings:

[0021] As shown in the accompanying drawings, a split drum type oil mist processor, characterized in that the processor includes an upper cover body 1, a lower cylinder body 2, a motor 3, a rotating shaft 4, and a rotary separation cylinder 5. The upper end of the upper cover body 1 is closed and provided with a groove. The middle part of the groove of the upper cover body 1 is fixedly connected with the motor 3. The output end of the motor 3 extends into the upper cover body 1 and is fixedly connected with the core shaft 4 of the rotary separation cylinder 5. The rotary separation cylinder 5 is provided with an oil outlet sieve hole 7. The separation blade 6 is fixedly connected to the inner wall of the rotary separation cylinder 5 body. The lower cylinder body 2 is sleeved outside the rotary separation cylinder 5. The upper cover body 1 and the lower cylinder body 2 are fixedly and hermetically connected through a buckle 8. The lower end of the lower cylinder body 2 is provided with an oil mist inlet 9. The groove of the upper cover body 1 is provided with an air outlet 10. The side surface of the upper end of the lower cylinder body 2 is provided with an oil outlet 11. The oil outlet 11 is connected with an oil outlet pipe 12. The spiral blade 13 is connected to the inner wall of the lower cylinder body 2. The lower end of the spiral blade 13 extends straight to the lower end of the lower cylinder body 2. The upper end of the spiral blade 13 extends straight to the position of the oil outlet 11.

[0022] Furthermore, the height of the upper cover body is the same as the height of the lower cylinder body, or the height of the lower cylinder body is 0.5 - 2 times the height of the upper cover body.

[0023] Furthermore, the spiral blade 13 is 0.8 - 1.5 spiral circumferences to ensure the oil drainage effect.

[0024] Furthermore, the lower end of the upper cover body 1 covers the outside of the upper end of the lower cylinder body 2. The lower end of the upper cover body 1 is provided with a slot 14 that cooperates with the position of the oil outlet pipe 12. Through the slot 14, it is ensured that while the upper cover body 1 covers the lower cylinder body 2, it can also be clamped with the oil outlet pipe 12.

[0025] Furthermore, the oil outlet sieve holes 7 on the body of the rotary separation cylinder 5 are distributed in blocks along the circumference of the body of the rotary separation cylinder 5. The part of the body of the rotary separation cylinder 5 between each block of oil outlet sieve holes 7 is a strengthening part 15. The separation blades 6 are fixed at the position of the strengthening part 15, ensuring the separation effect and at the same time increasing the structural stability of the body of the rotary separation cylinder 5.

[0026] Furthermore, a sealing plate 16 fixedly connected to the core shaft 4 is provided at the upper end of the body of the rotary separation cylinder 5. The sealing plate 16 is in a stepped groove shape. The stepped groove-shaped sealing plate 16 ensures the overall strength of the structure of the body of the rotary separation cylinder 5 and at the same time can increase the rotational stability of the body of the rotary separation cylinder 5.

[0027] Furthermore, the separation blade 6 is in a bent shape. One end of the separation blade 6 is fixedly connected to the body of the rotary separation cylinder 5, and the other end of the separation blade 6 extends towards the center of the body of the rotary separation cylinder 5.

[0028] In the present utility model, since the cylinder body of the original oil mist separator is divided into an upper cover body 1 and a lower cylinder body 2, and the height of the upper cover body 1 is 0 - 0.5 times the height of the lower cylinder body 2, the height of the upper cover body 1 is equal to that of the lower cylinder body 2, or the height difference between the upper cover body 1 and the lower cylinder body 2 is not large. Therefore, the height of the lower cylinder body 2 is shortened, which is more convenient for cleaning the lower cylinder body 2, with good cleaning effect and high cleaning efficiency. At the same time, since the oil outlet 11 is provided at the upper end of the lower cylinder body 2, and a spiral blade 13 for facilitating the export of oil is installed on the inner wall of the lower cylinder body 2, during the high-speed rotation of the centrifugal drum driven by the motor 3, a swirling upward air flow is formed inside the lower cylinder body 2, increasing the oil flow track formed by the spiral blade 13. When the air flow moves upward, the oil quickly spirals upward along the path of the spiral blade 13 and runs to the oil outlet 11. On the one hand, the structure of the spiral blade 13 can greatly enhance the outer discharge effect of oil mist, water mist, impurity particles, etc.; on the other hand, it can make the operation of oil mist, water mist, and impurity particles traceable and regular, and can also increase the discharge effect for viscous and easily adherent oily substances; at the same time, the air flow generated during the high-speed rotation of the centrifugal rotary separation cylinder 5 body will also increase the air flow and air volume spiraling upward along the spiral blade 13. Due to the adoption of the above structure, the present utility model has the advantages of simple structure, good oil mist separation effect, convenient maintenance, and easy discharge of the separated oil.
