The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

The utility model relates to a grease separation filter equipment, including spiral case 100, fan group and separating disc 300.

As shown in fig. 1 and 2, the middle portion and the side wall of the scroll casing 100 are opened, the middle opening of the scroll casing 100 serves as an air inlet 110, and the side wall opening serves as an air outlet 120. The fan assembly is mounted within the volute 100, preferably within the inlet 110 of the volute 100. The fan set comprises a motor 210 and a wind wheel 220, wherein the motor 210 drives the wind wheel 220 to rotate, so that outside air is sucked in from the air inlet 110 and exhausted from the air outlet 120. The separation disc 300 is installed at the air inlet 110, and the separation disc 300 covers the air inlet 110, so that under the pumping action of the fan set, the air flow needs to pass through the separation disc 300 and then enter the volute 100.

As shown in fig. 2 and fig. 3, in this embodiment, the air inlet 110 of the scroll casing 100 is circular, and the separation disc 300 is correspondingly circular. The middle of the separating disk 300 may be a solid 303, and the solid 303 is connected with the motor 210, so that the separating disk 300 and the wind wheel 220 are coaxial and rotate synchronously under the driving of the motor 210. The separating discs 300 may also be rotated synchronously or differentially with the wind rotor 220 using a different motor 210. The separating disk 300 extends from the central solid 303 to form a blade 310 in a radial direction, and the blade 310 may be in a linear strip shape, or a strip structure with a certain arc shape, etc. The plurality of blades 310 are spaced around the center from the middle of the separation disc 300, preferably, the blades 310 are spaced at equal intervals, and gaps with a certain width are formed among the blades 310. The end of each blade 310 remote from the center of the separation disc 300 may be connected to one of the rims 304. The blades 310 have a windward side 301 and a leeward side 302, depending on the direction of rotation of the separation discs 300. The separation discs 300 and the wind wheel 220 preferably rotate coaxially and in the same direction. The airflow will flow through the gaps of the vanes 310 of the separating discs 300. A flow guide groove 320 is provided on the windward side 301 of the blade 310. The guide grooves 320 extend along the length direction of the blades 310, i.e., guide the flowThe slot 320 extends from the center of the separator plate in the direction of the rim 304. The oil-fat separation and filtration device is applied to the range hood, and the absorbed gas is oil smoke. During operation, oil smoke enters the volute 100 along the axial direction of the air inlet 110 under the pumping action of the fan unit. At this time, the separation discs 300 rotate, and the rotation direction of the separation discs 300 is perpendicular to the inflow direction of the soot. When oil smoke flows through the gaps between the blades 310, the guide grooves 320 on the blades 310 strike, shear and strike the oil smoke, the surfaces of the guide grooves 320 are in contact with the oil smoke, and grease in the oil smoke adheres to the surfaces of the guide grooves 320, so that the grease is separated from the oil smoke. After the grease adheres to the guiding grooves 320, the grease is guided and collected towards the end of the blades 310 far from the center under the centrifugal action of the rotation of the separating discs 300. The gas after oil-smoke separation slides across the surface of the guiding groove 320 under the pumping action, and then flows through the gaps between the blades 310 to enter the air inlet 110. Before the grease enters the volute 100, the grease is firstly hit by the blades 310, the axial movement of the grease is changed into the radial movement along the guide grooves 320, and according to the air draft efficiency of the volute 100 and the fan set, according to the data measured by experiments, the rotating speed of the wind wheel 220 is 2000rpm, the wind speed of the air inlet 110 is 4.5m/s, the wind speed of the air outlet 120 is 12.65m/s, the static pressure of the air inlet 110 is 25.27pa, the relative atmospheric pressure of the air outlet 120 is 0pa, and the air volume is 0.318m ³ And/s, the grease separation rate of the separation disc 300 can reach more than or equal to 98 percent. Most of the grease is separated from the oil smoke by the separation disc 300 through shearing and collision, and the gas only carries a small part of grease to enter the air inlet 110, so that the grease amount in the oil smoke adhered to the air duct inside the volute 100 is effectively reduced, and the cleaning frequency of the inside of the volute 100 can be reduced for a user.

In some embodiments of the present invention, as shown in fig. 4 and 5, the longitudinal direction of the guiding grooves 320 is parallel to the axial direction of the separating disk 300, and the guiding grooves 320 are vertically sectioned from the outer side to the inner side of the separating disk 300, when viewed from the longitudinal section of the guiding grooves 320. The guiding grooves 320 have a first guiding surface 321 and a second guiding surface 322, and the first guiding surface 321 and the second guiding surface 322 both extend from the middle of the separating disc 300 to the rim 304. The first guiding surface 321 and the second guiding surface 322 are connected to each other, in this embodiment, the connection position of the first guiding surface 321 and the second guiding surface 322 is a cambered surface connection. The first flow guiding surface 321 and the second flow guiding surface 322 form a bent shape, which may be an L-shaped shape as shown in fig. 4. The guiding grooves 320 formed by the first guiding surface 321 and the second guiding surface 322 can be used as the wind-facing side 301 of the blade 310. During operation, the guiding grooves 320 shear the oil smoke, and the bent shapes of the first guiding surfaces 321 and the second guiding surfaces 322 have the functions of transversely cutting the air flow relative to the axial direction of the separating discs 300 and colliding the air flow parallel to the axial direction.

In particular, the first guiding surfaces 321 are located in a spatial plane transverse to the axial direction of the separation disc 300. As shown in fig. 5, the first guiding surfaces 321 are located on a spatial plane perpendicular to the axial direction of the separation disc 300. In the direction shown in fig. 3, the axial direction of the separation disk 300 is oriented forward and backward, the front side shown is the outer side of the separation disk 300, and the rear side shown is the inner side of the separation disk 300. The guiding grooves 320 face outward, and the first guiding surfaces 321 are parallel to the front side. It is also possible, as shown in fig. 6, that a virtual space plane 330 is drawn at the junction of the first flow guiding surface 321 and the second flow guiding surface 322, and the virtual space plane 330 is perpendicular to the axial direction of the separating disc 300. The first guiding surfaces 321 are inclined at an angle with respect to the virtual space plane 330, which is defined as a first inclination angle 331, and the first guiding surfaces 321 are inclined toward the inner side of the separating tray 300. When the flue gas flows through the separating disk 300, the first flow guiding surface 321 transversely cuts the flue gas, the grease hits the first flow guiding surface 321, and according to the rotating direction of the separating disk 300, the grease flows along the first flow guiding surface 321 toward the position connected with the second flow guiding surface 322, and then is collected along the flow guiding groove 320 toward the frame 304 under the centrifugal action. The air flows along the first guiding surface 321 to the interval between the two blades 310 under the pumping action of the fan set and enters the air inlet 110. The space angle of the first flow guiding surface 321 can shear the flue gas on one hand, and can ensure the flow of the gas on the other hand, thereby reducing the wind resistance.

The second guiding surface 322 has a striking and collision effect on the flue gas in parallel with the axial direction of the separating disk 300. Specifically, as shown in fig. 7, the second guide flow surface 322 is parallel to the axial direction of the separating disk 300, and the second guide flow surface 322 is perpendicular to the virtual space plane 330, with the virtual space plane 330 as a reference. It is also possible, as shown in fig. 6, that the second guiding surface 322 forms a second inclination 332 with the axial direction of the separating discs 300, which second inclination 332 is an acute angle. With the virtual space plane 330 as a reference, an included angle between the second guiding surface 322 and the virtual space plane 330 may be an obtuse angle, that is, the second inclination angle 332 may be as shown in fig. 6, and a thickness of the blade 310 between a front side of the second guiding surface 322 and the leeward side 302 of the blade 310 gradually increases toward the first guiding surface 321. It is also possible that the angle between the second flow guide plane 322 and the virtual space plane 330 may be an acute angle. During operation, second water conservancy diversion face 322 directly strikes on the flue gas along axial flow, and grease flows toward the junction along second water conservancy diversion face 322, and the air current then flows toward first water conservancy diversion face 321 along second water conservancy diversion face 322, increases the collision area when flue gas and guiding gutter 320 flow relatively, improves the efficiency of grease separation. Further, as shown in fig. 5, the second guiding surface 322 is configured as a wave surface having at least two wave troughs. The second flow guide surface 322 can be further increased in collision area with the flue gas along the wave shape from the outer side to the inner side.

Grease adheres to channels 320 and is then collected by centrifugal action of separator discs 300 as they rotate toward rim 304. In some embodiments of the present invention, an oil receiving ring 400 is disposed at the periphery of the separation disc 300, and the oil receiving ring 400 surrounds the periphery of the separation disc 300. An oil receiving groove is formed in the oil receiving ring 400, and the end of the vane 310 far from the center of the separation disc 300 extends into the oil receiving groove. An oil outlet is formed in the side wall of the oil receiving ring 400 and communicated to the oil receiving groove. According to the installation direction of the separation disc 300, the oil receiving ring 400 is correspondingly installed so that the oil outlet is at a low position. The grease of guiding gutter 320 gets rid of in the oil receiving groove, and the grease flows down along the oil receiving groove, then discharges from the oil-out.

The body 500 is mounted with components such as a circuit board, a control panel, etc. The smoke collection box 510 is connected to the machine body 500, and the grease separation filtering device is installed in the smoke collection box 510. During the use, organism 500 is towards the top of a kitchen range, and under grease separation filter equipment's pumping action, the flue gas enters into collection smoke box 510 through organism 500's smoking mouth, then carries out grease and gas separation through grease separation filter equipment and discharges. Wherein, in order to improve grease separation efficiency, along the flow direction of oil smoke, can carry out primary separation to the grease in the oil smoke at the smoke absorption mouth installation filter screen (not shown in the figure) of organism 500, rethread grease separator carries out the secondary separation.
