Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of oil mist and water mist purification, in particular to an oil mist and water mist purification device for a precision machining center. BACKGROUND

[0002] When the precision machining center uses oil cutting fluid, the high-speed friction between the tool and the workpiece generates high temperature, and the cutting oil evaporates after being heated. The steam condenses into tiny oil droplets when it cools down, forming oil mist, water mist, etc. The oil mist and water mist are distributed in the machining center, which is corrosive and polluting to metal parts. The purification device can filter and treat the particles in the oil mist and water mist, reducing the pollution of machining.

[0003] The patent with publication number CN215027080U discloses an oil mist purification filter structure, which includes a box body and a third filter screen, an impeller group, a second filter screen and a first filter screen arranged in the box body cavity from left to right. The left and right ends of the box body cavity are respectively provided with a first oil guide plate and a second oil guide plate. The left side of the impeller group is provided with a driving motor. The middle parts of the first filter screen and the second filter screen are connected with a second shaft through bearings. The left end of the second shaft is connected with a turntable through threads. The outer side of the turntable is annularly provided with a slot. The upper end of the second shaft is provided with a scraping brush mechanism. The scraping brush mechanism includes a supporting rod, a soft brush and a limiting nut. This oil mist purification filter structure can neither make the scraping brush mechanism rotate too fast to affect the filtration of the filter screen, nor improve the efficiency and effect of oil mist purification without additional equipment to provide power. While purifying the oil mist, the filter screen stains can be cleaned, improving the utilization of resources.

[0004] The patent with publication number CN216367048U discloses an efficient treatment device for oil mist purification, which includes a protection device, an oil mist filter body and a damping mechanism. The top of the protection device is provided with an oil mist filter body. The inner side of the protection device is provided with a damping mechanism. The protection device includes a protective cover. The inside of the protective cover is movably mounted with a purification case which has one end penetrating and extending above the protective cover. This efficient treatment device for oil mist purification can slow down the vibration force, thereby avoiding damage to the internal components of the purification case caused by external vibration force as much as possible. It can effectively buffer the vibration received by the oil mist filter body in the vertical direction, thereby quickly weakening the vibration force and helping the oil mist filter body to quickly recover to its original stable state in a short time, effectively improving the service life of the oil mist filter body.

[0005] A patent with publication number CN112933762A discloses a glass fiber filter core for oil mist purification, which comprises a frame and a composite layer. The composite layer is composed of several aluminum partitions and multiple layers of glass fiber filter layers. The multiple layers of glass fiber filter layers are in continuous S-shaped curved structures, and the semi-closed structure space in the S-shaped curved structure of the multiple layers of glass fiber filter layers is provided with aluminum partitions. The frame is provided around the outer periphery of the composite layer. The frame has different sealing forms, such as flat sealing type, knife edge embedding type and liquid tank sealing type. The filter core has the advantages of low running resistance, high purification efficiency, long service life and the like. However, when the content of oil particles and solid particles in some oil mist and water mist is high, the contact filtration with the filler (such as fiber filler, honeycomb filler, plate-type corrugated filler, etc.) will exceed the load capacity and separation threshold of the filler, and the filler will gradually form a deposition layer, which will cause the pore blockage of the filler in a short time, greatly reducing the purification efficiency. Moreover, the humidity of the oil mist and water mist is large, and part of the water mist is retained in the internal pores of the filler, which increases the resistance of other oil mist and water mist passing through the filler, further reducing the purification efficiency.

[0006] In view of the above problems, it is urgent to make innovative design on the basis of the original oil mist and water mist purification. SUMMARY

[0007] The present application aims to provide an oil mist and water mist purification device for precision machining center, to solve the problem that when the content of oil particles and solid particles in some oil mist and water mist is high, the contact filtration with the filler (such as fiber filler, honeycomb filler, plate-type corrugated filler, etc.) will exceed the load capacity and separation threshold of the filler, and the filler will gradually form a deposition layer, which will cause the pore blockage of the filler in a short time, greatly reducing the purification efficiency, and the humidity of the oil mist and water mist is large, and part of the water mist is retained in the internal pores of the filler, which increases the resistance of other oil mist and water mist passing through the filler, further reducing the purification efficiency.

[0010] Preferably, the shell is rotationally connected with a driving shaft, the driving shaft is coaxially connected with the bottom of the filter core, the bottom surface of the shell is provided with a base, the base is fixedly installed with a motor, and the output end of the motor is fixedly connected with the driving shaft; the bottom of the cylindrical barrel is provided with a plurality of through grooves penetrating the open end of the oil tank, and the bottom of the cylindrical barrel is coaxially fixed with an inner ring body penetratingly arranged at the center of the inner ring of the oil tank.

[0011] Preferably, the power mechanism includes a transmission branch rod laterally slidingly connected in the hollow pipe, and a vibrating disc is fixedly sleeved on the outside of the transmission branch rod close to the inner wall of the inner ring body; a positioning disc is fixedly sleeved on the outside of the transmission branch rod close to the outside of the inner ring body, and a vibrating spring is elastically connected between the positioning disc and the side wall of the inner ring of the oil tank, and the vibrating spring is sleeved on the outside of the transmission branch rod.

[0012] Preferably, a plurality of power frames are fixedly installed on the outside of the driving shaft along the axial direction, the power frames are kept in the same plane as the transmission branch rod, and the power frames are rotationally in contact with and extruded by the outer arc surface of the transmission branch rod.

[0013] Preferably, the upper end surface of the oil tank is coaxially fixed with a protective ring, and a flexible sealing ring is arranged between the protective ring and the cylindrical barrel.

[0014] Preferably, the drying mechanism includes a plurality of drying air holes opened on the outer wall of the hollow pipe; a heating pipe is fixedly installed on one end of the transmission branch rod close to the drying air hole, and a plurality of piston discs are fixedly sleeved on the outside of the heating pipe, and the outer wall of the piston disc is in close contact with the inner wall of the hollow pipe.

[0015] Preferably, the shell is provided with a wind power transmission mechanism for accelerating the transmission speed of oil mist and water mist in the adsorption filter channel.

[0018] Compared with the prior art, the oil mist and water mist purification device of the precision machining center has the beneficial effects that most oil particles and solid particles in the oil mist and water mist are separated by centrifugal and impact effects, the particle content is reduced, the probability of clogging the pores of the multi-layer plate filler is greatly reduced when the oil mist and water mist contact the multi-layer plate filler, and the plate filler can be uniformly dried and treated, thereby improving the time efficiency of the plate filler in purifying the oil mist and water mist.

[0021] The shell is provided with a wind transmission mechanism for accelerating the transmission speed of the oil mist and water mist in the adsorption filtration channel. The oil mist and water mist after centrifugation and impact enter the adsorption channel from the centrifugal purification channel.

Under the acceleration of the rotating fan blade, the speed of the oil mist and water mist moving in contact with the plate filler is improved, thereby assisting to improve the purification efficiency of the whole device.

The drying mechanism comprises a plurality of drying air holes 96 formed on the outer wall of the hollow tube 9; a heating pipe 97 is fixed to one end of the transmission branch 91 close to the drying air holes 96, a plurality of piston discs 98 are fixedly sleeved on the outer portion of the heating pipe 97, and the outer wall of the piston disc 98 is in close contact with the inner wall of the hollow tube 9.

[0040] The oil mist and water mist generated during the machining of the precision machining center are introduced into the open end of the filter core 2 through the negative pressure device, the oil mist and water mist enter the inside of the filter core 2, the motor 23 on the base 22 is controlled to rotate the driving shaft 21, the driving shaft 21 drives the filter core 2 to rotate, which makes the oil mist and water mist pass through the filter core 2 and centrifugally fly out (the penetration porosity of the filter core 2 is much larger than that of the plate filler 7, and the plugging rate is smaller), the centrifuged oil mist and water mist enter the centrifugal purification channel 101, and impact on the cylindrical barrel 3, most of the oil particles and solid particles in the inside of the cylindrical barrel 3 condense on the inner wall of the cylindrical barrel 3, and the oil droplets and water droplets formed by the movement and convergence of a plurality of oil particles and solid particles flow downward under the action of gravity, enter the inside of the oil tank 4 through the through slot 31, so that most of the particulate matters in the oil mist and water mist are separated, and the impacted oil mist and water mist move from the centrifugal purification channel 101 to the adsorption and filtration channel 102, the oil mist and water mist contact the plate filler 7 below the adsorption and filtration channel 102, pass through a plurality of plate fillers 7 and are filtered and purified, and the purified gas is discharged outward through the gas outlet hole 8 on the shell 1.

[0041] The driving shaft 21 drives the filter core 2 to rotate at the same time, the power frame 95 fixed outside the driving shaft 21 rotates synchronously, the power frame 95 rotates and contacts and extrudes the side of the protruding transmission support rod 91, when the transmission support rod 91 is extruded, it moves towards the hollow tube 9, the vibration disc 92 on the transmission support rod 91 impacts on the inner ring body 32, so that the inner ring body 32 vibrates, the vibration force on the inner ring body 32 is transmitted to the cylindrical barrel 3, the vibrating cylindrical barrel 3 can improve the impact force of the oil mist and water mist, so as to quickly separate the particulate matters in the oil mist and water mist and improve the separation effect, when the power frame 95 rotates away from the transmission support rod 91, the transmission support rod 91 moves outward and resets under the action of the pushing force of the vibration spring 94, so as to reciprocate continuously, the transmission support rod 91 can continuously reciprocate transversely, so that the cylindrical barrel 3 generates a sustained vibration force.

[0042] A heating tube 97 is fixed to the end face of the transmission support rod 91. The heating tube 97 is heated by an internal battery, and the heat is concentrated in the hollow tube 9. It is discharged outward through the drying vent 96 on the outer wall of the hollow tube 9. The transmission support rod 91 drives the heating tube 97 to move back and forth synchronously. The piston disc 98 fixed to the outside of the heating tube 97 moves laterally back and forth inside the hollow tube 9. In conjunction with the drying vent 96, it can draw gas from the gap between adjacent plate packings 7 into the interior of the hollow tube 9. After the gas mixes with the heat, it is discharged outward through the drying vent 96 under the thrust of the piston disc 98. The piston disc 98 pushes the gas to accelerate the flow rate of the discharged gas, so that the gas is evenly distributed between two adjacent plate packings 7. This ensures that the plate packings 7 can be heated and dried more evenly, reducing the water content in the plate packings 7. This prevents water mist from clogging the pores of the plate packings 7 and increasing the penetration resistance, thereby improving the purification efficiency of the purification device for oil mist and water mist.

[0043] Example 2: Please refer to Figures 11-13 Based on Embodiment 1, a wind-powered transmission mechanism is also disclosed, the specific structure of which is as follows: A wind-powered transmission mechanism is provided in the housing 1 to accelerate the transmission speed of oil mist and water mist in the adsorption and filtration channel 102. Multiple protective covers 10 are fixed at equal angles along the axial direction on the inner top surface of the housing 1. Fan blades 11 are rotatably installed in the protective covers 10, and the multiple fan blades 11 are arranged in a ring corresponding to the top of the adsorption and filtration channel 102. A small gear 12 is coaxially fixed on the fan blade 11, and a gear ring 13 is meshed with the small gear 12. The gear ring 13 is fixedly installed on the outside of the filter element 2. A side groove 14 is opened on the side of the protective cover 10 near the gear ring 13, and the gear ring 13 passes through the side groove 14.

[0044] During the rotation of the filter element 2, the externally fixed toothed ring 13 rotates synchronously. The toothed ring 13 passes through the side groove 14 on the protective cover 10 and meshes synchronously with multiple small gears 12. It can control the rotation of multiple fan blades 11 installed in the protective cover 10. The rotation of the fan blades 11 accelerates the gas flow in the adsorption filtration channel 102, so that the gas in the adsorption filtration channel 102 is quickly transported downward to contact the plate packing 7, which helps to improve the purification efficiency. Secondly, the rotation of the fan blades 11 can help dry the plate packing 7, further reduce the moisture content in the plate packing 7, and maintain its high-efficiency filtration effect.
