Description

Technical Field

[0001] This utility model relates to the field of air purifier technology, and in particular to a horizontal oil mist purifier. Background Technology

[0002] With economic development, global manufacturing is increasingly shifting to China; my country's machine tool industry is transitioning from a growth stage to a period of rapid development and maturity, becoming the world's largest machine tool manufacturing and processing country. In industrial production, when processing equipment cuts metal, the high-speed, high-intensity friction between the equipment and the metal generates oil mist; this oil mist not only pollutes the environment but also adheres to the skin and eyes of workers, harming their physical and mental health.

[0003] Currently, Chinese utility model patent CN206121352U discloses an industrial oil mist purifier, including a housing and an internal filter layer, an electric actuator, a differential pressure gauge, and an oil mist recovery device. The left side of the housing is the air inlet, and adjacent to the air inlet are the primary and secondary filter layers, which are vertically arranged inside the housing and extend to the top and bottom of the housing. The electric actuator is located in the middle of the housing. The tertiary filter layer is distributed between the middle of the housing and the electric actuator. The oil mist recovery device is located at the bottom of the filter layer in the housing. The differential pressure gauge is used to display the internal pressure of the housing. The quaternary filter layer is located at the air outlet on the right side of the housing. The differential pressure gauge is connected to the signal input terminal of the alarm device. When the value of the differential pressure gauge is greater than or equal to a certain value, the alarm device automatically sounds an alarm.

[0004] However, in existing oil mist purifiers, the electric motor is positioned directly opposite the air intake. The electric motor draws air into the purifier for purification through the air intake. Because the suction force is stronger on the side facing the electric motor, the air entering the purifier is concentrated in a localized area of ​​the filter layer, which can easily cause localized blockages in the filter layer. This prevents the filter layer from being fully utilized, increases the frequency of filter cleaning, and is detrimental to air purification. Utility Model Content

[0005] The purpose of this invention is to provide a horizontal oil mist purifier, which has the advantage of dispersing the air drawn into the purifier within the purifier, thus facilitating air purification.

[0006] To achieve the above and other related objectives, this utility model provides the following technical solution:

[0031] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides a horizontal oil mist purifier, including a housing 1, an air inlet 4, an air outlet 5, a centrifugal fan 7, a filter module 12, an oil drain hole 16, and a flow equalization plate 17.

[0032] A partition 21 is vertically welded and fixed inside the housing 1. A suction ring 22 is provided in the middle of the partition 21. The partition 21 divides the interior of the housing 1 into a filter chamber and a fan chamber 3. The suction port 4 is located on the side wall of the housing 1 and is connected to the filter chamber. The exhaust port 5 is located on the top of the housing 1 on the side away from the suction port 4 and is connected to the fan chamber 3.

[0033] Centrifugal fan 7 is installed in fan chamber 3 below exhaust port 5. Centrifugal fan 7 is used to generate negative pressure to draw air from air intake port 4 into housing 1. Filter module 12 is installed in filter chamber between air intake port 4 and centrifugal fan 7. Oil drain hole 16 is installed on housing 1 at the bottom of filter module 12. Flow equalization plate 17 is fixedly installed in filter chamber at air intake port 4. Flow equalization plate 17 is used to disperse the airflow drawn into filter chamber.

[0034] Please refer to Figure 3 A support frame 24 is welded and fixed to the inner wall of the housing 1 located at the air intake 4. A flow equalization plate 17 is welded and fixed to the support frame 24. The flow equalization plate 17 has a conical structure with its tip facing the air intake 4. The flow equalization plate 17 is coaxially arranged with the air intake 4. When oil mist-containing air enters through the air intake 4, it is evenly distributed, divided, and dispersed by the flow equalization plate 17, thereby dispersing the air inside the purifier and avoiding the airflow directly impacting the local area of ​​the filter module 12, which is more conducive to air purification.

[0035] Please see Figure 2 , Figure 3 and Figure 4Multiple sets of frame-shaped channel steel 18 are arranged on the inner walls of the box 1 located on one side of the flow equalization plate 17, forming multiple sets of frame-shaped slots 19; the filter module 12 includes a filter 121, a filter screen 122, and a filter element 123, which are inserted and fixed in the frame-shaped slots 19; in this embodiment, the filter 121 is a PTFE sintered stainless steel filter 121, which is used to filter large particles of oil mist; the filter screen 122 is a 4PTFE sintered stainless steel filter screen 122, which is used to filter small particles of oil mist and fumes; the main filter element can be made of multi-layer composite material, which is used to filter out fine oil mist and fumes in the air; multi-stage filtration of oil mist in the air is achieved, meeting the needs of multi-layer interception and filtration of oil mist, with high purification efficiency and purification degree.

The oil collected in the oil collection box 20 can be reused after subsequent purification.

[0037] Please see Figure 3 A fan frame 6 is bolted to the partition 21, and the fan frame 6 is located inside the fan chamber 3. The centrifugal fan 7 includes a motor 71 bolted to the fan frame 6 and an impeller 72 fixedly connected to the output shaft of the motor 71. The impeller 72 is located on the side close to the suction ring 22. When the motor 71 drives the impeller 72 to rotate, the airflow enters the housing 1 through the suction hole and passes through the flow equalization plate 17 and the filter module 12 in sequence before entering the fan chamber 3 through the suction ring 22. Finally, clean air is discharged from the exhaust port 5.

[0038] Please see Figure 1 and Figure 2 An enhanced filtration module 23 is provided on the outer casing 1 of the exhaust port 5.

In this embodiment, the secondary filter element 232 can also be made of multi-layer composite material.

[0039] Brief description of the operation process: After the equipment is started, the centrifugal fan 7 generates negative pressure suction force, and the polluted air around the machine tool is drawn into the filter chamber through the air intake 4. In the filter chamber, the air is evenly distributed, divided and dispersed by the flow equalization plate 17, thereby dispersing the air inside the purifier. After the air is filtered through multiple stages by the filter module 12, it enters the fan chamber 3 through the air intake ring 22, and finally the clean air is discharged from the exhaust port 5. The oil mist separated by the filter module 12 is discharged from the oil outlet and enters the oil collection box 20. The oil collected in the oil collection box 20 can be purified and reused.

[0040] If this purifier is used in situations where a higher level of purification is required, an enhanced filtration module 23 is installed on the housing 1. The enhanced filtration module 23 is used to filter extremely fine oil mist and fumes in the air. After passing through the four-stage filtration of the purifier, the air containing oil mist and fumes becomes clean and dry.

[0041] In summary, the purifier of this invention, through multi-stage filtration and modular design, effectively solves the environmental pollution problem caused by traditional oil mist treatment methods, while simultaneously achieving the recycling of cutting fluid. It boasts advantages such as high purification efficiency, compact structure, and convenient installation and maintenance, making it suitable for various industrial processing environments.
