Technical Field

The present invention relates to a fluid separation device and a processing apparatus, and more particularly, to a fluid separation device and a processing apparatus for separating a mixed fluid.

Background

When cutting crystals, the cutting fluid in the cabin door of the processing equipment can evaporate under the action of the cutting heat, the steam of the cutting fluid is condensed into tiny droplets in the cabin, and the tiny droplets absorb tiny dust particles in the cabin to form a dust mixture. As the cutting operation proceeds, part of the dust mixture collides with each other, increases in volume and naturally falls, and the remaining part of the dust mixture having a diameter of 10um or less floats in the cabin for a long time.

The dust removing pipe for sucking the dust mixture is arranged in the processing equipment, and after the dust mixture is sucked into the dust removing pipe, the dust mixture may collapse the dust removing pipe along with the aggregation of the dust mixture. Meanwhile, hardening phenomenon can occur after moisture of the dust mixture in the dust removing pipeline is evaporated, so that the pipeline is blocked, the air quantity in the pipeline is reduced, and the dust removing effect of the dust removing pipeline is affected. In addition, the dust removal pipeline with hardening phenomenon is difficult to clean, the workload of operators can be increased, and the production progress is influenced.

Therefore, it is a technical problem to be solved at present, how to design a device capable of separating dust mixture for those skilled in the art.

As shown in fig. 1 and 2, a preferred embodiment of the present invention provides a fluid separation device, which includes a separation part 1, the separation part 1 includes a flow director 11, an exhaust pipe 12 and a flow guiding channel 13, a flow guiding inlet 131 and a flow guiding outlet 132 are provided on the flow guiding channel 13, the exhaust pipe 12 is inserted into the flow guiding outlet 132, and a gap 14 is provided between the air pipe 12 and the flow guiding outlet 132. The fluid director 11 is positioned within the fluid directing channel 13 and is configured to move the mixed fluid entering from the fluid directing inlet 131 such that a less dense fluid is discharged from the exhaust pipe 12 and a more dense fluid is discharged from the gap 14.

As shown in fig. 1, a preferred embodiment of the present invention also provides a processing apparatus including a dust removing pipe (not numbered) for sucking a mixed fluid generated in a cabin of the processing apparatus, and a fluid separating device. The fluid separation device is communicated with the dust removing pipeline and is used for separating mixed fluid in the dust removing pipeline.

The fluid separation device provided by the invention can realize the separation of the mixed fluid, so that the mixed fluid is prevented from being condensed in the dust removal pipeline after being evaporated, the service life of processing equipment is prolonged, and the dust removal effect of the processing equipment is ensured.

It should be noted that the processing equipment in the present application can be applied to the fields of machinery, semiconductors, solar energy, etc. Meanwhile, the application working conditions of the processing equipment are not limited to cutting of metal materials or nonmetal materials, and the processing equipment can be also suitable for working conditions such as polishing, welding and polishing of the metal materials or nonmetal materials. In the working condition, the mixed fluid generated by the metal material or the nonmetallic material during processing can be separated by adopting the fluid separation device.

Further, the diversion inlet 131 is used for being connected with a dust removing pipeline, so that mixed fluid in the dust removing pipeline is led into the fluid separation device, and the mixed fluid is separated through the fluid separation device.

When in actual use, the number of the fluid separation devices and the dust removal pipelines can be multiple, and at the moment, the fluid separation devices can be connected to each dust removal pipeline of the processing equipment so as to fully separate the mixed fluid in each dust removal pipeline, and the separation effect of the processing equipment on the mixed fluid is improved.

It should be understood that the mixed fluid in the present application may be a mixed gas, and the mixed fluid may also be a gas-liquid mixture formed by mixing a gas and a liquid. The application is not limited to the kind of the mixed fluid. For example, in cutting metallic or nonmetallic materials, the mixing fluid may be a mixture of various kinds of dust, and the mixing fluid may also be a mixture of cutting fluid droplets and dust. For another example, when polishing or grinding metallic or non-metallic materials, the mixing fluid may be a mixture of various kinds of dust, and the mixing fluid may be a mixture of cooling liquid and dust.

In a preferred embodiment, the deflector 11 comprises a deflector vane. Specifically, the deflector 11 includes a plurality of deflector blades (not numbered) for uniformly dispersing the mixed fluid, all of which are connected to each other and uniformly distributed in the circumferential direction. Because the densities of the components of the mixed fluid are different, the centrifugal forces applied to the fluids with different densities are different when the fluids with different densities flow, so that the flow track of the fluids with different densities is different, and the fluids with different densities can be separated through the fluid separation device. The arrangement of the guide vane can improve the separation efficiency of the fluid separation device, ensure the purity of the gas discharged by the exhaust pipe 12 and has great application prospect.

When the mixed fluid is a gas-liquid mixture, the guide vane is used for changing the movement direction of the mixed fluid so as to separate the gas and the liquid in the mixed fluid, so that the gas in the mixed fluid is discharged from the exhaust pipe 12, and the liquid in the mixed fluid is discharged from the gap 14, thereby realizing the gas-liquid separation of the mixed fluid by the fluid separation device.

Referring to fig. 1 and 2, in a preferred embodiment, the guide vane is fixed in the guide passage 13 while the guide vane is not rotated. After the mixed fluid enters the guide channel 13 through the guide inlet 131, the mixed fluid flows along the arc of the guide vane. Due to the density difference between the gas and the liquid, the flow track of the gas and the liquid in the mixed fluid is different under the action of the inertia force of the guide vane so as to separate the gas and the liquid in the mixed fluid.

In another preferred embodiment, the guide vane is rotatably disposed in the guide passage 13, in which case the guide vane can rotate in its own circumferential direction to apply work to the mixed fluid. When the mixed fluid enters the diversion channel 13 through the diversion inlet 131, the mixed fluid rotates under the combined action of the centrifugal force and the inertial force of the diversion blades, so that the mixed fluid generates a uniform rotational flow effect. Because the density of each component of the mixed fluid is different, the centrifugal force applied to the gas and the liquid in the mixed fluid during the rotation movement is different, so that the flow track of the gas and the liquid in the mixed fluid is different, and the gas and the liquid in the mixed fluid can be separated.

Further, after the mixed fluid passes through the action of the guide vane, the gas with smaller density in the mixed fluid moves at the middle part of the guide channel 13 (i.e. the position close to the central axis of the guide channel 13) and is discharged from the exhaust pipe 12; while the denser liquid in the mixed fluid moves substantially against the inner wall of the diversion channel 13 and out of the gap 14 between the exhaust pipe 12 and the diversion outlet 132.

Preferably, an annular gap is formed between the exhaust pipe 12 and the diversion outlet 132, in other words, the outer wall of the exhaust pipe 12 has a gap with the inner wall of the diversion outlet 132 on the whole circumference, at this time, the liquid separated from the mixed fluid can flow out through any position in the annular gap, so as to improve the gas-liquid separation efficiency of the fluid separation device.

With continued reference to fig. 1 and 2, the fluid separation device further comprises a storage portion 2, the storage portion 2 comprising a collection chamber 21, the collection chamber 21 being in communication with the separation portion 1 and being adapted to collect liquid discharged through the gap 14, i.e. the fluid separation device is adapted to store liquid separated from the mixed fluid through the collection chamber 21.

Preferably, the storage part 2 further includes a drain pipe 22, the drain pipe 22 being in communication with the collection chamber 21 and being for discharging the liquid in the collection chamber 21. In one embodiment, the liquid separated from the mixed fluid may flow through drain 22 into a sump within the processing equipment compartment.

Referring to fig. 1, in a preferred embodiment, the number of the separation parts 1 is plural, all the separation parts 1 are arranged at intervals in a direction perpendicular to the central axis of the exhaust pipe 12, and all the separation parts 1 are preferably arranged at intervals in the vertical direction in sequence. All the separating portions 1 are in communication with the collecting chamber 21 through a corresponding one of the gaps 14, that is, the gap 14 of each separating portion 1 is in communication with the collecting chamber 21, so that the collecting chamber 21 can collect the liquid separated in all the separating portions 1 to facilitate the concentrated treatment of the liquid.

In this embodiment, the fluid separation device further comprises a housing 3, all separation parts 1 being placed in the accommodation space of the housing 3. The collection chamber 21 is provided below the housing 3 and communicates with the bottom of the housing 3. The liquid flowing out of the gap 14 of each separation part 1 can enter the accommodation space of the housing 3 and flow into the collection chamber 21 below the housing 3.

In a preferred embodiment, the central axis of the exhaust pipe 12, the rotation axis of the guide vane 11 and the central axis of the guide channel 13 (i.e. the extending direction of the guide channel 13) are parallel or coincident, preferably coincident, at this time, the arrangement direction of the rotation axis of the guide vane 11 and the outflow direction of the gas in the guide outlet 132 are the same, so that the gas separated in the guide vane 11 can always move along the axial direction of the guide channel 13 until being discharged from the exhaust pipe 12, and the smoothness of gas discharge is improved.

As shown in fig. 1 and 2, in an exemplary embodiment, the internal profile of at least a portion of the exhaust pipe 12 gradually decreases toward the diversion inlet 131, i.e., the exhaust pipe 12 has a bell mouth structure, and the cross section of the exhaust pipe 12 gradually decreases along the direction from the diversion outlet 132 to the diversion inlet 131. So constructed, the caliber of the exhaust pipe 12 is gradually increased along with the outflow of the gas in the diversion channel 13, so as to further improve the fluency of the gas flow and the working efficiency of the fluid separation device.

With continued reference to fig. 1 and 2, the separating portion 1 further comprises an air inlet duct 15, the air inlet duct 15 being in communication with the diversion inlet 131. Further, the air inlet pipe 15 is used for connecting with a dust removing pipe, so that mixed fluid in the dust removing pipe is led into the diversion channel 13 through the diversion inlet 131.

Optionally, the internal profile of at least a portion of the section of the air inlet pipe 15 gradually decreases in the direction of the pilot outlet 132, i.e. the cross section of the air inlet pipe 15 gradually decreases in the direction of the pilot inlet 131 to the pilot outlet 132. The gas flow rate in the diversion channel 13 can be improved, so that the separation efficiency of the fluid separation device is improved under the action of the diversion device 11.

As a preferred solution, the central axis of the air inlet pipe 15, the central axis of the air outlet pipe 12, the central axis of the guide channel 13 and the rotation axis of the guide vane 11 are all coincident, and at this time, the inflow direction of the mixed fluid in the air inlet pipe 15, the outflow direction of the air in the air outlet pipe 12, and the extending direction of the guide channel 13 are all the same as the arrangement direction of the rotation axis of the guide vane 11. After the mixed fluid flows in along the extending direction of the diversion channel 13, the separated gas can be discharged along the extending direction of the diversion channel 13 under the action of the deflector 11, so that the mixed fluid always flows along the same direction (namely, the flowing direction) in the fluid separation device, and the fluency of the gas flow is further improved.

In summary, in the fluid separation device and the processing equipment provided by the application, the fluid separation device can realize the separation of the mixed fluid, so that the mixed fluid is prevented from being condensed in the dust removal pipeline after being evaporated, the service life of the processing equipment is prolonged, and the dust removal effect of the processing equipment is ensured.

The above description is only illustrative of the preferred embodiments of the present invention and is not intended to limit the scope of the present invention, and any alterations and modifications made by those skilled in the art based on the above disclosure shall fall within the scope of the present invention.
