Description

Oil mist recovery machine

The present invention relates to an air purifying device, in particular to an oil mist recovery machine which can reduce the frequency of filter elements of the filter unit due to oil mist obstruction, relatively reduce the cost of filter material replacement, and ensure or even extend the service life of the drive motor in the exhaust unit.

When using automated machinery for machining operations, it is often necessary to use various types of cutting oil or coolant to lubricate the tool and reduce the processing temperature of the workpiece, so it also produces a large amount of oil mist, water mist, dust, etc. in the working environment. , causing physical hazards on the site operators; most factories will install ventilation devices, or install protective covers, splash guards, etc. around the machine, but it is still difficult to solve these substances. Possible harm.

Because the above-mentioned method of exhausting indoor oil mist, water mist, dust and other substances to the outside of the factory by means of exhausting equipment is still caused by environmental pollution, the oil mist filter is installed on the machine or the periphery. The oil mist, water mist or dust generated during the machining process is collected, and the harmful substances are adsorbed and intercepted by multi-stage interception and filtration, and finally the clean gas is discharged. .

In order to achieve this, an oil mist recovery structure known in the prior art, such as the new patent publication No. 549136, discloses an oil mist filter which is provided on the front and rear sides of the body of the oil mist filter. At the central part, a front air chamber, a middle air chamber and a rear air are separately formed and formed. The chambers are connected to each other, and filter cotton is arranged inside each of the air chambers, and the motor drives the blower fan in the middle air chamber, so that the dirty air can be sucked from the front air chamber, and sequentially Through the middle air chamber and discharged in the rear air chamber, and the dirty air flows in each air chamber, the various sizes of the microparticles contained in the belt are gradually blocked by the filter cotton, thereby obtaining the back gas. The room discharges the fresh air after filtration.

However, the above oil mist filter completely blocks and absorbs all substances (including water mist, oil mist and dust), and must be provided with multi-layer filter cotton in each air chamber, which is easy to block and needs to be replaced frequently. This has led to an increase in filtration costs and needs to be improved.

The new patent No. M436140 discloses an oil mist filtering device, which comprises: a casing, a base and a top shell formed, the base recessed to form an oil collecting space, and a filtering space is arranged inside the top shell And a suction space, the direction of the filtering space and the suction space is defined as an axial direction, and the filtering space is formed in the axial direction with a relatively one air inlet communicating with the outside of the casing, and a suction port a suction space is formed, and the suction space is formed with a set of openings corresponding to the suction port, and a bottom of the suction space is formed with an exhaust port communicating with the oil collecting space of the base, and the bottom of the filtering space and the oil collecting Each of the bottoms of the space is formed with an oil hole; a casing is formed into a hollow structure, and an inlet and an outlet connected to the oil collecting space of the casing are formed on both sides of the top and bottom, and the casing corresponds to the casing group At the mouth, a receiving port is formed along the axial direction; a filtering unit has a spoiler formed into a circular arc porous structure, and is arranged convexly toward the inlet of the top casing, so that a first filter and a first filter a second filter is disposed on the spoiler and the Between the top casing suction ports; a draft unit having a wind wheel disposed in the casing suction space, and a motor housed in the casing receiving port, the wind wheel being coupled to the motor and Driving rotation; a filter cartridge is hollow inside and has an inner filter layer and an outer filter layer formed on the cylinder wall, the filter cartridge has two ends, one end of which is closed, and the other end Forming an opening to be connected to the outlet of the casing, whereby the oil mist filtering device sucks oil mist from the air inlet of the casing, so that the oil mist is filtered by the filtering unit, and the suction space and the oil collecting space are After the inside of the casing, the inner and outer filter layers of the filter cartridge are filtered and purified to form a clean gas and discharged into the atmosphere.

However, in the above-described oil mist filtering device, the first one, when initially sucking oil mist, water mist, dust, and the like into the inside of the filtering space by the suction force generated by the air blowing unit, still contains all the substances (including water mist and oil mist). And the dust is completely blocked and absorbed, and the filter screen of the filter unit is easily blocked and needs to be replaced frequently, resulting in an increase in the filtration cost. Otherwise, if the filter unit of the filter unit is not frequently replaced, the oil mist will pass through the filter. The resistance can not be effectively improved, resulting in a decrease in the oil mist volume. Therefore, it is necessary to increase the motor speed to achieve the proper diversion effect, so that the motor is easily degraded or even destroyed due to overheating, which inevitably increases the recovery cost; secondly, it passes the wind. The residual oil mist guided by the wheel to the oil collecting space can enter the filter cylinder for secondary filtration through an outlet above the oil collecting space, but the inhaled oil mist flow before entering the filter cartridge First, it flows down the slope of the oil collecting space, and then rises upwards. During this time, the rising airflow is shunted around and has a motor. After the cage positions, cage and finally into the outlet of the secondary filter cartridge, so that virtually the drag of the oil mist and the gas flow pressure loss is too large, the separation effect is greatly reduced by filtration and the filter cartridge.

The new patent No. M510786 discloses a high-efficiency oil mist recovery machine comprising: a casing unit, a first filtering unit, a second filtering unit and a draft unit, the casing unit having sequential communication An air inlet, a first air chamber, a second air chamber, and a pair of air guiding openings that pass through the outside and the second air filtering unit is disposed above the air guiding opening; wherein the first The filter unit is disposed in the first air chamber and corresponds to the air inlet. The first filter unit has a tapered front cover, a pluggable unit is inserted into the air duct, and an outer diameter is larger than the front a cover and a filter set connected between the front cover and the rear cover; and the air suction unit has a drive motor, and a vortex guide fan pivotally located with the drive motor and located in the second air chamber, The vortex diversion fan is disposed in the same axial direction as the first filter unit, and has a plurality of equally spaced blades thereon; the second filter unit is disposed above the air guiding port; and when the operator activates the driving motor The power supply drives the vortex diversion fan to rotate, and the centrifugal wind pressure generated when the vortex diversion fan rotates is used to introduce oil mist, dust and exhaust gas from the air inlet into the first air chamber through the air inlet. The front cover of the first filter unit is guided by a spiral vortex-like flow guiding portion to accelerate the disturbance of the intake air flow, and the swirling air flow makes the wind speed collision more moderate, which contributes to the uniform air guiding effect, so that The first filter unit uses a filter material group to trap most of the oil mist and dust, and since the back cover of the first filter unit forms a large diameter outlet, a large air volume can be formed, and the wind resistance and pressure loss of the filter group can be reduced. Effect to make the oil mist flow The gas can be rapidly dialyzed into the second air chamber, and then the residual oil mist after the front oil-air separation treatment is completed by the first filtering unit, and the vortex diversion fan can be directly pumped by the upper air guiding port. The second filter unit is internally filtered again, and finally, the clean gas passing through the second filter unit can be directly discharged to the outside.

In the oil mist filtering device, the first filter unit is installed in the first gas chamber and corresponds to the air inlet, and a spiral eddy current guiding portion is disposed at the front end of the first filter material. The front cover, in particular, the front cover is disposed at the front end of the first filter material in a state of "fixed and does not rotate, and the front end of the first filter unit is closed"; therefore, when the oil mist recovery machine initially borrows the suction unit thereof When the powerful centrifugal air pressure is generated and the oil mist, water mist, dust and the like are sucked into the first air chamber, as described in the paragraph [0028] of the new patent specification, the front cover is used. A structural design provides an operator to start the power supply of the driving motor to drive the vortex diversion fan to rotate, and to use the centrifugal wind pressure generated when the vortex diversion fan rotates, the oil mist in the plant area, Dust and exhaust gas are introduced into the first air chamber from the air inlet, and the front cover of the first filter unit is guided by a spiral eddy flow guiding portion to accelerate the disturbance of the intake air flow, and the swirling air flow The wind speed collision is more moderate, which helps the uniform air guiding effect, and the first filtering unit uses the filter material group to trap most of the oil mist and dust.

However, this structural design will still have the following shortcomings: First, the main purpose of the front cover is mainly as a uniform air conduction, so that the first filter unit can retain most of the oil mist and dust, so it is still as Like the above-mentioned several oil mist recovery machines, the first filter material is easily blocked and needs to be replaced frequently, resulting in an increase in filtration cost.

Secondly, since the first filter unit is installed in the first air chamber and corresponds to the air inlet, the front cover is in a state of being "fixed and does not rotate, and the front end of the first filter unit is closed". At the front end of the first filter material, and the main purpose of the front cover is to serve as a uniform air guide, when the operator is provided to start the power supply of the drive motor, the vortex guide fan is driven to rotate, and the vortex guide fan is rotated. When the oil mist, dust, and exhaust gas in the plant are introduced into the first air chamber from the air inlet, the oil mist and dust can be attached even when the front cover is touched for the first time. The amount of oil mist, water and liquid on the outer surface of the front cover and gradually falling on the bottom of the first air chamber by the self-gravity such as oil mist and water liquid is quite limited, and almost all the oil mist, water liquid and dust All of them must be disturbed by the spiral vortex-like flow guiding portion of the front cover of the first filter unit to disturb the intake air flow, and the first filter unit uses the filter material group to apply most of the oil mist and dust. Interception, making the oil mist recovery machine still as before Several recycling machine learning-type mist-like, its first filter clog easily and need frequent replacement, resulting in increased filtration costs. Otherwise, if the first filter unit is not replaced frequently, the resistance of the oil mist penetrating through the filter screen will not be effectively improved, resulting in a decrease in the oil mist air volume, so that the motor speed must be increased to achieve the proper diversion effect, so that drive The motor is prone to a decrease in life or even damage due to overheating, which inevitably increases the cost of recovery and is to be improved.

This creation is an oil mist recovery machine. The lack of improvement in this creation is that the improvement of the oil mist recovery machine still requires that most of the substances (oil mist, water mist, dust) entering the oil mist recovery machine be blocked and absorbed by the filter unit, resulting in frequent filtration units. Replace the problem of increased filtration costs.

In order to achieve the foregoing objective, the present invention provides an oil mist recovery machine including: a box unit, a first filter unit, a second filter unit, and a draft unit; wherein the box unit has sequential communication An air inlet, a first space, a second space, and a pair of air guiding openings corresponding to the second space and extending through the outside, the first filtering unit being installed in the first space and corresponding to the air inlet, the second a filter unit is disposed above the air guiding port, the air blowing unit has a driving motor and a vortex guiding fan axially located in the second space, and is disposed at the front end of the first filtering unit a scroll type fan wheel, and an oil collecting unit is arranged on both sides of the first space-vortex fan wheel, and when the oil mist recovery machine uses the suction force generated by the rotation of the vortex deflector fan of the air blowing unit, directly drives the oil When the blade of the scroll fan wheel rotates, when the external oil mist is sucked into the first space from the air inlet, the centrifugal force generated by the rotation of the blade of the scroll fan wheel can strongly force the oil mist and the liquid liquid out. And being single The oil collecting unit provided on both sides of the first space formed by the interior is adsorbed and separated as oil and gas, and the fluid after the oil intercepting can be easily sucked into the second space through the first filtering unit, and sent along the air guiding port. The second filter unit is used for the post-stage filtration separation, so as to reduce the frequency of the first filter unit and the second filter unit to be replaced due to the oil mist blockage, and the effect of the filter unit replacement cost is relatively greatly reduced.

The outer ring seat 24 is provided with a recovery oil hole 241 and a partition plate 25 at the bottom of the outer ring seat 24. The front cover 21, the outer cover 22 and the rear cover 23 are hollow inside. Inside the box cover 22 The front cover 21 is separated from the rear cover 23, and a through hole 251 is defined in the center of the partition 25. The first space 26 and the second space 27 are formed inside the box unit 2, wherein the box A recovery oil hole 261 is defined in the bottom of the first space 26 formed inside the body unit 2, and an air guiding port 28 is formed through the second space 27 above the second outer space 27.

The first filter unit 3 is disposed in the first space 26 formed inside the box unit 2, and is a hollow multi-layer filter body (the filter material content, structure and technology of the filter body are conventionally used, so The principle is not described in detail. The front end of the box unit 2 corresponds to the air inlet 211 provided in the center of the box cover 21, and the rear end thereof is detachably mounted on the partition plate 25 by a combination member 31.

The second filter unit 4 is an axially hollow multi-layer filter body (the filter material content, structure and technology of the filter body are conventionally used, so the principle technology is not described above), and is detachably mounted on the outer ring. Block 24 on.

The ventilating unit 5 includes a driving motor 51, a vortex guide fan 52, and a wind drum 53. The driving motor 51 is mounted on the rear box cover 23 by a motor fixing plate 511. The guide fan 52 is pivotally disposed in the second space 27 with the drive motor 51. The vortex guide fan 52 is disposed in the same axial direction as the first filter unit 3, and has a plurality of equally spaced blades thereon. The ventilating fan 53 accommodates the vortex guide fan 52, and a flow guiding port 531 is disposed above the vortex guide fan 52 to provide wind pressure from the venting opening 531. The air guiding port 28 provided above the outer cover 22 of the box is smoothly introduced into the second filter unit 4.

The most important feature of the present invention is that a scroll type fan wheel 6 is disposed at the front end of the first filter unit 3, and the first space position scroll fan wheel 6 formed inside the box unit 2 is divided into two sides. An oil collecting unit 7 is provided, the oil collecting unit 7 includes a oil collecting seat 71 and a set of oil collecting slivers 72 set on the oil collecting seat 71; thereby, when the operator activates the power of the driving motor 51, The vortex guide fan 52 is driven to rotate, and the oil mist, dust and exhaust gas in the plant area are introduced into the first space 26 by the air inlet 211 by the centrifugal wind pressure generated when the vortex guide fan 52 rotates. At this time, the centrifugal force generated by the rotation of the vane of the scroll fan 6 can force most of the oil mist and the liquid liquid to be separated as oil and gas, wherein the oil mist and water are taken out. The liquid can be collected by the oil collecting sliver 72 in the oil collecting unit 7 which is formed on both sides of the first space 26 inside the tank unit 2, and is collected after the oil collecting sliver 72 adsorbs a certain oil mist and water liquid.
