DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Referring to FIGS. 1 and 2, wherein FIG. 1 shows a perspective view of a multiple inlets cyclo-filtration hydrocyclone of the present invention, while FIG. 2 is a cross-section view illustrating the hydrocyclone separator of the present invention. As illustrated, the multiple inlets cyclo-filtration hydrocyclone separator 1 of the present invention includes a separator body 10, multiple feeders 20 and 20-2a, 20-2b etc., an upstream outlet 30, a downstream outlet 40 and a filtering unit 50. The separator body 10 defines a hollow chamber, has an upper body part 11 of a cylindrical shape and a lower body part 13 of a truncated cone shape extending downward and gradually narrow relative the upper body part 11 in diameter. The feeders 20, 20-2a and 20-2b are connected helically to the upper body part 11 from a lateral side thereof for feeding a raw liquid thereinto. The feeders can enhance the centrifugal force. The upstream outlet 30 in the form of a hollow cylinder is disposed axially within the separator body 10, has an upper part projecting upward axially and outwardly from the upper body part 11 and lower part extending into the lower body part 13. The downstream outlet 40 is attached axially to a lowermost end of the lower body part 13 and in spatially communication with the lower body part 13. The filtering unit 50 is disposed axially within an inner wall confining the upstream outlet 30, has an upper part projecting upwardly and outwardly from a top end of the upstream outlet 30 and a lower part extending into the downstream outlet 40. The filtering unit 50 consists of a filtering membrane having an inner wall 55 (see FIG. 3) confining the filtering member.

[0014] In this embodiment, the separator body 10, the feeders 20, 20-2a and 20-2b, the upstream outlet 30, the downstream outlet 40, and the filtering unit 50 are integrally formed with one another. In another embodiment, the separator body 10, the feeders 20, 20-2a and 20-2b, the upstream outlet 30, the downstream outlet 40, and the filtering unit 50 are independently fabricated and are later assembled together in order to form the hydrocyclone separator 1 of the present invention.

[0015] FIG. 3 shows a cross-section view of the filter unit in the hydrocyclone separator 1 of the present invention. As shown, the filtering unit 50 includes a coupler head 51 defining the upper part projecting upwardly, axially and outwardly from the top end of the upstream outlet 30 for connected spatially to an exterior pipe(not shown) and a filtering tube 53 that is defined by the inner wall 55 of the filtering membrane and that projects downward from the coupler head 51 in such a manner to extend within a bottom end of the downstream outlet 40. Preferably, the filtering membrane is selected from a group consisting of a ceramic membrane, a glass fiber membrane, Polyvinylidene fluoride (PVDF) membrane, a Teflon membrane, an active carbon membrane and a resinous ion exchange membrane.

[0016] When a raw mixed fluid is fed into the separator body 10 via the feeders 20, 20-2a and 20-2b, due to different characteristic of the solid molecules and liquid molecules in the raw mixed fluid, the relatively large particles in the raw mixed fluid will collide against the inner wall of the separator body and flows downstream(known as underflow) due to the centrifugal force caused due feeding operation of the raw mixed fluid. Hence, the large particles are collected via the downstream outlet 40. Since a vortex flow is caused simultaneously within the inner wall of the upstream outlet 30, the small particles are pushed axially upward so as to be collected via an exterior pump (not shown). In addition, portions of the downstream flow or upstream flow are passed through the filtering unit 50 so as form the clarified liquid such that the clarified liquid in collected at the top or bottom end of the filtering unit 50 with the assistance of an exterior pump (not shown). In other words, when the hydrocyclone separator 1 of the present invention is utilized, the large and small particles can be collected simultaneously via the downstream flow and the upstream flow caused within the separator body 10 via the feeders 20, 20-2a and 20-2b. In addition, the clarified liquid can be collected simultaneously via a filtering tube.

[0017] The feature of the hydrocyclone separator of the present invention resides in that since the filtering unit 50 is implemented within the hydrocyclone separator, once the raw mixed fluid is fed thereinto, the large and small particles and the clarified liquid can be collected simultaneously in addition to that the separator can be easily operated and is low in cost.

[0018] Note that the prior art hydrocyclone separator has one single inlet and two outlets, i.e., overflow and underflow liquids respectively. However, the hydrocyclone separator of the present invention also has multiple inlets but three outlets, i.e., overflow and underflow liquids and the clarified liquid respectively.

[0019] It can get filtrate F0 LPM(L/min) when using traditional filtration system under same filter, same filtration area. It can get filtrate F1 LPM using the prior art hydrocyclone (U.S. Pat. No. 8,184,286). While using the invention when there are two inlets, the filtrate is F2 LPM. When using the invention with three inlets, the filtrate is F3 LPM. The following results are satisfied.

F3>F2>F1>F0   1.

F1>1.2*F0  2.

F2>1.1*F1  3.

F3>1.05*F2.   4.

[0020] While the invention has been described in connection with what is considered the most practical and preferred embodiments, it is understood that this invention is not limited to the disclosed embodiments but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
