Description

filter

The embodiment of the present invention relates to a filtering device, in particular to a filtering device capable of forming a controllable speed spiral flow field.

Filter materials are commonly used in the industry to filter liquids to obtain the desired filtrate, where the filter materials have different porosities to filter larger size particles.

The traditional filtering method is to let the liquid pass through the filter material, and use the different porosity of the inner and outer layers of the filter material to catch the large-sized particles, and let the desired small-sized particles or clean filtrate pass through to achieve the filtering effect. Because the direction of the feed flow and the direction of the filtrate are generally the radial direction of the filter medium, although some large-sized particles will be caught on the outer layer of the filter medium, the other part will also flow to the inner layer of the filter medium due to the feed pressure. It is easy to be pushed to the inside of the filter material due to the pressure difference caused by the small pores in the inner layer of the filter material, and it will flow out with the clean filtrate or the filtrate containing the desired small size particles, resulting in a reduction in the life cycle of the filter material or poor filtration efficiency. .

Therefore, there is a need to provide a filtering device, which can improve the filtering efficiency and extend the life cycle of the filtering medium.

The purpose of the present invention is to propose a filtering device which improves the filtering efficiency and prolongs the life cycle of the filtering medium.

In some embodiments, the liquid to be filtered enters the filtering unit in a third tangential direction.

In some embodiments, the transport liquid enters the filter unit in a fourth tangential direction.

In some embodiments, the liquid to be filtered enters the filtering unit through a first position of the filtering unit, and the transported liquid enters the filtering unit through a second position of the filtering unit, wherein the first position and the second position are arranged diagonally.

The embodiments of this disclosure are discussed in detail below. It is understood, however, that the embodiments provide many applicable concepts that can be embodied in a wide variety of specific content. The embodiments discussed and disclosed are for illustration only and are not intended to limit the scope of the disclosure. In addition, the terms “first”, “second”, and the like used in this document do not specifically mean the order or the order, and they are only used to distinguish elements or operations described in the same technical terms.

Please refer to FIGS. 1 and 2. FIG. 1 is a schematic top view of a filtering unit 11 and a liquid flow direction of a filtering device 1 according to an embodiment of the present invention. It also shows the direction of liquid flow and the transport unit 12. In this embodiment, the filtering device 1 includes a filtering unit 11 and a conveying unit 12.

1 and FIG. 2, the filtering unit 11 is configured to filter the liquid to be filtered, and the liquid to be filtered enters the filtering unit 11 in a first tangential direction D1 of the filtering unit 11. In this embodiment, the filter unit 11 uses a two-layer filter element as an example. The filter unit 11 includes an outer layer filter element 111 and an inner layer filter element 112 located within the outer layer filter element 111, and the two are arranged in a concentric circle and connected to each other. In addition, in general, the porosity of the outer filter element 111 is greater than the porosity of the inner filter element 112, whereby the outer filter element 111 can filter larger size particles, and the inner filter element 112 can filter smaller size particles. The filtrate (filtered liquid) produced by the filtration unit 11 may have smaller particles or almost no particles, which may depend on the desired application. The filtering unit 11 further has a hollow portion 113 located inside the inner filter element 112, and the filtrate can flow out from the top or bottom of the hollow portion 113. Here, the filtrate is taken out from the bottom of the hollow portion 113 as an example.

Here, there is no restriction on how the liquid to be filtered enters the filtering unit 11, which can be guided by a housing, a hose, or a pressurized conveyance of a pressure motor, for example. In this embodiment, the liquid to be filtered enters the filtering unit 11 in the first tangential direction D1. The definition of the first tangent direction D1 is described below. The liquid to be filtered enters the filtering unit 11 through the first position P1 of the filtering unit 11, and the first tangential direction D1 is related to the first position P1 of the filtering unit 11. In other words, after the first position P1 is selected, it is determined that the first tangent direction D1 is the tangent direction of the first position P1. Here, according to industry practice, the first position P1 does not refer to a single point, but refers to a range, for example, a range is defined such that its width or length is less than or equal to 1/2 of the radius of the filter unit 11.

In addition, due to the above-mentioned definition of the first position P1, or a manufacturing error, or other reasons, the first tangential direction D1 of this embodiment does not refer to the tangential direction exclusively, but is substantially in the vertical three-axis direction (X-axis , Y-axis, and Z-axis) may have some margin. The tangent direction here is, for example, the vertical direction of the line connecting the center point of the first position P1 to the center of the filter unit. For example, in an embodiment of the present invention, the first tangent direction D1 substantially includes a direction deflected within an angular range in a tangent direction corresponding to the first tangent direction, and this angular range may be ± 20 degrees (as shown in FIG. 3A); in another embodiment of the present invention, the angle range may be ± 15 degrees (as shown in FIG. 3B); in another embodiment of the present invention, the angle range may be ± 5 degrees (as shown in FIG. 3C). The first all-line direction D1 is within the above range, and the advantages of the new model can be achieved to some extent.

In addition, as shown in FIG. 2, the liquid to be filtered enters from the top of the filtering unit 11 in the first tangential direction D1, but the present invention is not limited thereto, and the liquid to be filtered can enter the filtering unit 11 from different heights. Moreover, in some applications, such as large-sized filter units or three or more layers of filter elements, the liquid to be filtered can enter the filter unit 11 in the third tangential direction, that is, there are multiple feed ports, and the feed The mouths can be located at different heights. The third tangent direction may be the same as the definition of the first tangent direction D1, and details are not described herein again.

Please refer to FIG. 1 and FIG. 2, the conveying unit 12 of the filtering device 1 extracts the liquid to be delivered from the periphery of the filtering unit 11 to output the conveying liquid, and the conveying liquid enters the filtering unit 11 in the second tangential direction D2 of the filtering unit 11. The conveying unit 12 includes, for example, a pump, a pressurizing motor, etc., and can extract the liquid to be sent from the periphery of the filter unit 11 and output the conveyed liquid. The periphery includes, for example, the filter unit 11 and the housing 13 containing the filter unit 11 (please first See Figure 7). In this embodiment, the second tangential direction D2 may be the same as the above-mentioned first tangential direction D1. The liquid to be filtered enters the filtering unit 11 through the second position P2 of the filtering unit 11, and the second tangential direction D2 and the filtering unit 11 The second position P2 is related. For other parts, reference may be made to the previous description, so it will not be repeated here.

In addition, as shown in FIG. 2, the conveyed liquid enters from the top of the filter unit 11 in the second tangential direction D2, but the present invention is not limited thereto, and the conveyed liquid can enter the filter unit 11 from different heights. Furthermore, in some applications, such as large-sized filter units or applications with more than three layers of filter elements, the conveyed liquid can enter the filter unit 11 in the fourth tangential direction, that is, there are multiple return ports. The fourth tangent direction may be the same as the above-mentioned first tangent direction D1. I will not repeat them here.

In addition, as shown in FIG. 1, in this embodiment, the first position P1 and the second position P2 of the filtering unit 11 are arranged diagonally. Of course, the present invention is not limited to this. The first position P1 and the second position P2 may have other configurations, for example, the phase angle between the first position P1 and the second position P2 is 45 degrees.

The conveying unit 12 of this embodiment can control the flow rate of the conveyed liquid according to needs or applications. For example, the conveyance unit 12 controls the flow rate of the conveyed liquid according to the flow rate, pressure, or particle parameters of the liquid to be conveyed. Here are some examples of implementation.

As shown in FIG. 4A, the conveying unit 12 includes a flow rate detector 121, a control element 122 a and a pump 123, and the control element 122 a is electrically connected to the flow rate detector 121 and the pump 123. The flow rate detector 121 is configured to detect the flow rate of the liquid to be sent, and the control element 122a controls the flow rate of the pump 123 to output the liquid flow according to the detected flow rate.

As shown in FIG. 4B, the conveying unit 12 includes a pressure detector 124, a control element 122b, and a pump 123, and the control element 122b is electrically connected to the pressure detector 124 and the pump 123. The pressure detector 124 is configured to detect the pressure of the liquid to be sent, and the control element 122b controls the flow rate of the pump 123 to output the liquid according to the detected pressure.

As shown in FIG. 4C, the conveying unit 12 includes a particle parameter detector 125, a control element 122c, and a pump 123, and the control element 122c is electrically connected to the particle parameter detector 125 and the pump 123. The particle parameter detector 125 is configured to detect particle parameters of the liquid to be sent, such as the number, proportion, or other parameters related to particles of particles larger than 1 micron. Control element 122c The detected particle parameter controls the flow rate of the pump 123 to output the liquid.

In addition, in some applications, the conveying unit 12 may be configured so that the flow rate of the liquid to be conveyed and the flow rate of the liquid to be filtered into the filtering unit are matched with each other. For example, in one mode, when the flow rate of the liquid to be filtered into the filter unit is too slow, the conveying unit 12 can increase the flow rate of the liquid to be transferred; in another mode, when the flow rate of the liquid to be filtered into the filter unit is increased, the conveying unit 12 can increase the flow rate of liquid. In addition, in some applications, the conveying unit 12 may provide a cleaning mode. For example, when the flow rate of the liquid to be filtered or the liquid to be sent is too slow, it means that the filtering unit 11 is clogged, and the conveying unit 12 can increase the flow rate of the conveying liquid for a period of time to form a high-speed spiral flow field for cleaning and filtering Unit 11 eliminates back pressure conditions. In addition to the above, high-speed spiral flow fields can be applied in other situations where required. In addition, in a mode, when the flow rate of the liquid to be sent decreases, the flow rate of the liquid to be filtered entering the filtering unit 11 and the flow rate of the liquid to be sent can be increased at the same time.

FIG. 5 is a schematic perspective view of the filtering device 1 according to the present embodiment, FIG. 6 is a schematic top view of the filtering device 1 according to the present embodiment, and FIG. 7 is a schematic cross-sectional view of the filtering device 1 according to the present embodiment. As shown in FIG. 7, the filtering device 1 includes a filtering unit 11, a conveying unit 12, and a housing 13. The filtering unit 11 and the conveying unit 12 have been described in detail above, and will not be repeated here.

As shown in FIG. 6, the housing 13 includes a housing portion 131, one or more input portions 132, one or more return portions 133, and an output portion 134. As shown in FIG. 7, the casing portion 131 is hollow, and the filtering unit 11 is accommodated in the casing portion 131.

Please refer to FIG. 6 and FIG. 7 at the same time. The input portion 132 is disposed on the casing. The portion 131 may be formed integrally with the housing portion 131, for example. The liquid to be filtered enters the filtering unit 11 in the first tangential direction D1 through the input portion 132. The input portion 132 extends along at least a portion near the filtering unit 11 or the housing portion 131 along the first tangential direction D1, so that the liquid to be filtered enters the filtering unit 11 in the first tangential direction D1.

Please continue to refer to FIG. 6 and FIG. 7, the returning portion 133 is disposed on the housing portion 131 and can be formed integrally with the housing portion 131, for example. The conveyed liquid enters the filter unit 11 in the second tangential direction D2 through the return section 133. The return portion 133 extends at least in a portion near the filter unit 11 or the housing portion 131 along the second tangent direction D2, so that the liquid to be filtered enters the filter unit 11 in the second tangent direction D2. Although FIG. 5 and FIG. 7 show three return units 133, in practice, it is not necessary to use three at the same time, but they can be applied as required. In addition, although FIG. 5 and FIG. 7 show that the three return sections 133 are arranged in a row, they may have another positional arrangement, such as a staggered arrangement.

As shown in FIGS. 5 and 7, the output portion 134 is provided on the top side of the housing portion 131. Here, the output portion 134 is exemplified by the opening of the housing portion 131.

In the present embodiment, as shown in FIG. 7, the conveying unit 12 is connected to a part of the housing 13, and the conveying unit 12 is located below the filter unit 11 and is connected to the housing portion 131 as an example. In this way, the conveying unit 12 can directly extract the liquid to be delivered from the outside of the filtering unit 11, that is, the space between the housing 13 and the filtering unit 11, and discharge the conveying liquid from the outlet 126 of the conveying unit 12. The fixing member F communicates with the outlet 126 and is used for fixing a conveying pipe (not shown) connected to the returning section 133 so that the conveyed liquid enters the filtering unit 11 through the conveying pipe and the returning section 133.

The above-mentioned embodiments are merely examples, and are not intended to limit the present invention. In other embodiments, the casing 13 may have various variations, for example, the casing 13 does not have a protruding input portion 132 and a return portion 133, and these structures are only formed by the opening of the casing portion 131 and the delivery pipe. Alternatively, in another embodiment, the conveying unit 12 is disposed outside the casing 13 and is connected to the conveying unit 12 by a conveying pipe, which can also reduce the size of the casing 13.

To sum up, the present invention proposes a filtering device that allows the liquid to be filtered to enter the filtering unit in the first tangential direction of the filtering unit, and causes the transported liquid output by the conveying unit to enter the filtering unit in the second tangent direction of the filtering unit. A spiral flow field is formed, wherein the spiral flow field can be controlled by the conveying unit to reach a high-speed spiral flow field. Therefore, the new type can greatly reduce the probability that large-sized particles will block the inner filter element, thereby improving the filtering effect and extending the life cycle of the filtering unit.

In addition, the flow rate of the conveyed liquid is not affected by the porosity of the filtering unit, but is controlled by the conveying unit. Therefore, it can provide a high-speed and effective spiral flow field, which can expand the application range and improve product competitiveness, such as this new type of filtration. The device can be applied to large-sized filter units, multi-layer filter elements, or specific operating modes that can be performed by high-speed spiral flow fields.
