Description

DESCRIPTION
TECHNICAL FIELD
[0001] The present invention relates to a controlled cavitation device.
BACKGROUND OF THE INVENTION
[0002] A cavitation device is disclosed in EP 610914. This device comprises a housing defining a chamber formed by a cylindrical side wall and a pair of end plates, a shaft passing through an axis of the chamber and a rotor mounted on the shaft within the chamber so as to rotate with the shaft.
[0003] The rotor has a surface toward the side wall provided with uniformly-spaced inwardly-directed recesses or bores at a selected angle. These recesses produce turbulence of fluid within a cavitation zone defined between the rotor and the inner surface of the chamber.
[0004] This device comprises also an inlet port for the introduction of fluid into the space between the rotor and the inner surface of the chamber and an outlet port for the removal of treated fluid. A first and a second fluid connections are connected to the inlet and outlet ports which are oriented axially or radially in the two proposed embodiments.
[0005] A different cavitation device is disclosed in EP 1289638. In this device an inlet port is axially provided on either side of the housing in order to equalize the hydraulic pressure on the rotor and an outlet port is radially provided in the housing in the cylindrical wall of the housing to communicate with the cavitation zone in a region of the rotor intermediate or between the arrays of bores.
[0006] The position of the outlet port ensures that the entire volume of the gas/liquid mixture traverses at least one of the arrays of bores and thus moves through the cavitation zone prior to exiting the housing.
[0007] The mixing device from publication US 2011 081 384 is also known and discloses the preamble of claim 1. This device has the input and output ports arranged tangentially to the cavitation chamber.
[0008] The cavitation devices mentioned above suffer of problem when treating abrasive fluids, such as biological fluid, manure, sewage, waste, mud any other fluid which incorporates solid particles that may create friction.
[0009] In fact, with the cavitation devices of the prior art, the fluid must vary suddenly its direction and speed when enters and/or exits the chamber of the housing. This change of the direction and speed of the fluid causes wear of the inlet and outlet ports.
[0010] In view of the above prior art, the object of the present invention is to provide a cavitation device where the direction and speed of the fluid entering and exiting the chamber of the housing is controlled thereby preventing damage of the inlet and outlet ports.
SUMMARY OF THE INVENTION
[0011] According to the present invention, this purpose is fulfilled by a cavitation device according to claim 1.

DETAILED DESCRIPTION
[0013] Referring to the appended figures, figure 1 shows a cavitation device 10 coupled with an electric motor 1 to define a cavitation apparatus 100.
[0014] The cavitation device 10 comprises a shaft 11, a housing 20 and a rotor 30.
[0015] The shaft 11 extends along an axial direction X-X and is configured to be coupled with the electric motor 1. In particular, the electric motor 1 comprises a driving shaft 2 coupled with the shaft 11 of the cavitation device 10 through transmission means 3 to put in rotation the shaft 11.
[0016] The housing 20 defines a cylindrical chamber 21 having a inner cylindrical surface 21a and has a fluid inlet port and 22 and a fluid outlet port 23.
[0017] Preferably, the housing 20 has one single fluid inlet 22 and one single fluid outlet 23.
[0018] The rotor 30 is arranged within the cylindrical chamber 21 of the housing 20 and is mounted on the shaft 11 to rotate about a rotor axis X extending along the axial direction X-X.
[0019] A fluid inlet conduit 24 is coupled to the fluid inlet port 22 for supplying fluid into the cylindrical chamber 21 of the housing 20. This fluid inlet conduit 24 has an inlet axis B extending along an inlet direction B-B.
[0020] A fluid outlet conduit 25 is coupled to the fluid outlet port 23 for receiving fluid from the cylindrical chamber 21 of the housing 20. This fluid outlet conduit 25 has an outlet axis C extending along an outlet direction C-C.
[0021] The housing 20 comprises a first side wall 26a and a second side wall 26b axially spaced from the first side wall 26a along the axial direction X-X.
[0022] The housing 20 comprises also a cylindrical body 27 extending axially between the first side wall 26a and the second side wall 26b and joining the first and second side walls 26a, 26b. The cylindrical body 27 and the first and second side walls 26a, 26b define the cylindrical chamber 21 of the housing 20.
[0023] The rotor 30 comprises a first side surface 31 and a second side surface 32 axially spaced from the first side surface 31 along the axial direction X-X.
[0024] The rotor 30 comprises also a cylindrical peripheral surface 33 extending axially between the first side surface 31 and the second side surface 32 and joining the first and second side surfaces 31,32.
[0025] The radial distance between rotor axis X and the cylindrical peripheral surface 33 defines the rotor radius R of the rotor 30.
[0026] The axial distance between the first side surface 31 and the second side surface 32 defines the axial extension of the rotor 30.
[0027] At least two arrays of bores 34 are formed in the cylindrical peripheral surface 33. In the example shown in the figures, the rotor 30 comprises three arrays of bores. The bores 34 of each array of bores are arranged in a row extending around the cylindrical peripheral surface 33.
[0028] Each bore 34 extends radially into the rotor 30 from the cylindrical peripheral surface 33.
[0029] A cavitation zone 35 is defined between the cylindrical peripheral surface 33 of the rotor 30 and the inner cylindrical surface 21 a of the cylindrical chamber 21 of the housing 20.
[0030] The cylindrical chamber 21 comprises an inlet cylindrical chamber 28a formed between the first side surface 31 and the first side wall 26a and an outlet cylindrical chamber 28b formed between the second side surface 32 and the second side wall 26b.
[0031] The fluid inlet port 22 is positioned in the housing 20 to introduce fluid into the inlet cylindrical chamber 28a at an axial position spaced apart from the first side surface 31 of the rotor 30.
[0032] The fluid outlet port 23 is positioned in the housing 20 to receive fluid from the outlet cylindrical chamber 28b at an axial position spaced apart from the second side surface 32 of the rotor 30.
[0033] According to the invention, the axial distance between the fluid inlet port 22 and the first side surface 31 of the rotor 30 is equal to or greater than the axial extension of the rotor 30.
[0034] According to the invention, the axial distance between the fluid outlet port 23 and the second side surface 32 of the rotor 30 is equal to or greater than the axial extension of the rotor 30.
[0035] The inlet direction B-B of the inlet axis B is perpendicular to the axial direction X-X of the rotor axis X and the outlet direction C-C of the outlet axis C is perpendicular to the axial direction X-X of the rotor axis X.
[0036] Preferably, the fluid inlet conduit 24 and the fluid outlet conduit 25 are arranged on the stator 20 such that the fluid supplied through the fluid inlet port 22 and delivered through the fluid outlet port 23 follows within the cylindrical chamber 21 a helical path. The inlet axis B and the outlet axis C are substantially tangential to this helical path.
[0037] With this arrangement of the inlet an outlet axes B and C relative to the rotor axis X and thanks to the axial position of the fluid inlet and outlet ports 22, 23, it is possible to control the tangential speed of the fluid supplied into the housing 20 and received from the housing 20 reducing any effect of suction and delivery.
[0038] The inlet cylindrical chamber 28a and the outlet cylindrical chamber 28b make available two chamber so that, in use, the mass of fluid axially arranged before the rotor 30, in the inlet cylindrical chamber 28a, and after the rotor 30, in the outlet cylindrical chamber 28b, guarantee a rotational inertia which opposes the axial speed of the fluid, with respect to the radial and tangential speed set by the speed of the rotor 30.
[0039] As a consequence, the axial speed of the fluid is independent from the speed of the rotor 30 and the cavitation is thereby controlled.
[0040] This arrangement is extremely advantageous with abrasive fluids, however it can be used with benefit also with non-abrasive fluids and for mixing liquid-liquid, liquid-gas and liquid solid supplied through the fluid inlet conduit 24.
[0041] According to one embodiment, the inlet port 22 is positioned in the housing 20 to introduce fluid into the inlet cylindrical chamber 28a at an axial position adjacent to the first side wall 26a of the housing 20 and the outlet port 23 is positioned in the housing 20 to receive fluid from the outlet cylindrical chamber 28b at an axial position adjacent the second side wall 26b of the housing 20.
[0042] According to a preferred embodiment, the fluid inlet conduit 24 and the fluid outlet conduit 25 are positioned such that the inlet axis B and the outlet axis C are parallel to and proximate to respective tangential directions to the cylindrical peripheral surface 33 of the rotor 30 or to respective tangential directions to the inner cylindrical surface 21a of the cylindrical chamber 21 of the stator 20.
[0043] More preferably, the fluid inlet conduit 24 and the fluid outlet conduit 25 have respective first portions 24a, 25a facing a respective plane, in the example a same plane P', passing through the rotor axis X and parallel to the corresponding inlet axis B and outlet axis C and opposite second portions 24b, 25b. The second portions 24b, 25b of the fluid inlet conduit 24 and the fluid outlet conduit 25 join the stator 20 substantially tangentially to the inner cylindrical surface 21 a of the cylindrical chamber 21 of the stator 20.
[0044] In the example shown in the figures, the inlet axis B and the outlet axis C are parallel.
[0045] According to one embodiment, the distance between the outlet axis C and the rotor axis X along a direction Y-Y perpendicular to the outlet axis C and the rotor axis X ranges between 70% and 100% the rotor radius R.
[0046] The same applies to the distance between the inlet axis B and the rotor axis X along a direction Y-Y perpendicular to the inlet axis C and the rotor axis X which ranges between 70% and 100% the rotor radius R.
[0047] In particular, the inlet axis B and the outlet axis C intersect a plane P passing through the rotor axis X and perpendicular to the inlet and outlet axes B, C at a distance D from the rotor axis X between 70% and 100% the rotor radius R.
[0048] Preferably, the housing 20 comprises two lateral portions 20a, 20b defined at opposite sides relative to the plane P passing through the rotor axis X and perpendicular to the inlet and outlet axes B, C.
[0049] In the example shown in the figures, the fluid inlet port 22 and the fluid outlet port 23 are positioned on one of the two lateral portions 20a, 20b, namely in the lateral portion 20a.
[0050] Those skilled in the art will obviously appreciate that a number of changes and variants may be made to the arrangements as described hereinbefore to meet incidental and specific needs.
[0051] For example, unless otherwise imposed by evident technical limitations, any feature described in a preferred embodiment may be clearly used in another embodiment, with appropriate adaptations.
[0052] All the changes will fall within the scope of the invention, as defined in the following claims.
