[0041] See Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 The utility model is a sewage centrifugal separation device, which includes:
[0042] The accommodating unit 10 comprises a first accommodating portion 11, a second accommodating portion 12, and a longitudinally narrowed connecting portion 13. The first accommodating portion 11 comprises an upper opening 111, an upper conical plate 112, a lower conical plate 113, and a central support 114; these components enclose a first space S1. The upper opening 111 is located at the top of the upper conical plate 112; the central support 114 is coaxial with the upper opening 111 and located at the top of the lower conical plate 113. The second accommodating portion 12 defines a second space S2; the longitudinally narrowed channel 13 connects the first space S1 and the second space S2.
[0043] The water inlet unit 20 is provided on the receiving unit 10 and penetrates and communicates with the first space S1 and is higher than the central support 114. The water inlet unit 20 is used to supply sewage 90 (such as Figure 8 As shown), the sewage 90 includes at least one liquid object 91 and at least one solid object 92 (refer to Figure 9A 、 Figures 9B to 9C ).
[0044] The upper discharge unit 30 is disposed at the upper opening 111 and communicates with the first space S1 .
[0045] The lower discharge unit 40 is disposed in the second receiving portion 12 and communicates with the second space S2 .
[0046] The centrifugal transmission unit 50 is provided in the accommodating unit 10. The centrifugal transmission unit 50 has a driving portion 51 and a blade portion 52. The driving portion 51 is provided in the central support 114 and extends into the second space S2. The blade portion 52 is located in the second space S2 and is connected so as to be driven by the driving portion 51 to rotate, thereby driving the sewage 90 in the first space S1 to rotate centrifugally. The at least one liquid object 91 is discharged from the upper discharge unit 30 along the upper conical plate 112 and the upper opening 111. The at least one solid object 92 is thrown toward the longitudinal narrow connecting portion 13 (such as the lower conical plate 113) by centrifugal force (the relevant drawings are for illustration only and will be described first). Figure 9A As shown), and then moved by gravity through the longitudinal narrow connecting portion 13 to the second receiving portion 12 (as shown Figure 9B and Figure 9C As shown), the wastewater is discharged through the lower discharge unit 40 to form a centrifugal separation device.
[0047] In practice, see Figure 4 and Figure 6 There may be an offset distance D between the water inlet unit 20 and the upper opening 111 (axis), so that when the sewage 90 is supplied, the sewage 90 can flow in a vortex in the first space S1 in conjunction with the centrifugal force.
[0048] The first space S1 is defined between the upper conical plate 112 and the lower conical plate 113. The upper conical plate 112 has a first angle θ1 (e.g. Figure 7 As shown), the lower conical plate 113 has a second angle θ2, and the first angle θ1 is greater than the second angle θ2.
[0049] For example, the first angle can be 30 degrees, and the second angle θ2 can be 15 degrees, which has a good centrifugal separation effect. Of course, it can also be modified to other angles.
[0050] Then the first space S1 has a first height H1 (such as Figure 8 As shown) and a second height H2, the first height H1 is higher than the second height H2;
[0051] The first height H1 is adjacent to the upper opening 111 ; and
[0052] The second height H2 is adjacent to the longitudinal narrow connecting portion 13 .
[0053] In this way, the first space S1 is gradually reduced from the inside to the outside and gradually moves downward (with Figure 8 for example).
[0054] It is important to note that, as is well known in the relevant industry, wastewater from poultry and livestock farming (i.e., wastewater 90 in this case) consists of at least solid feces (i.e., solid matter 91 in this case) and liquid urine (i.e., liquid matter 92 in this case). Sedimentation is required to separate the solid feces and liquid urine before they can be processed (e.g., recycled). However, the sedimentation process is time-consuming and inconvenient. This case addresses this issue with the following features:
[0055] [a] First feature: The centrifugal transmission unit 50 is provided to drive the sewage 90 in the first space S1 to centrifugally rotate.
[0056] By centrifugal force, the at least one solid object 92 is centrifugally thrown along the lower conical plate 113 toward the longitudinal narrow connecting portion 13 (such as Figure 9A As shown), combined with the impact force (part of the liquid object 91 will still impact downward) and gravity (the gravity of the solid object 92 itself), it moves downward from the longitudinal narrow connecting portion 13 to the second space S2 (as shown). Figure 9B As shown), and then can be discharged by the lower discharge unit 40 (as shown Figure 9C As shown). A centrifugal separation device is achieved. That is, solid-liquid separation can be achieved without time-consuming sedimentation.
[0057] Of course, the lower discharge unit 40 can be a through-port structure or a valve structure. When it is a valve structure, it can remain normally open and directly discharge the at least one solid object 92. When the at least one solid object 92 is plural, the opening time can also be controlled to output the solid objects 92 accumulated to a predetermined amount.
[0058] That is, the first and second spaces S1 and S2 are connected in a “vertical” manner, so that the at least one solid object 92 can be quickly thrown into the second space S2 by impact force and gravity, and then discharged through the lower discharge unit 40.
[0059] For example, the at least one solid object 92 may be moved from the first position P1 (eg, Figure 9A As shown, located in the first space S1), the second position P2 (as shown Figure 9B As shown, located at the longitudinal narrow connecting portion 13), the third position P3 (as Figure 9C As shown, the lower discharge unit 40 is moved from the second space S2 to the fourth position P4 (also located in the second space S2 ), and then discharged.
[0060] Regarding the first position P1, the second position P2, the third position P3 and the fourth position P4 of the at least one solid object 92 in each view ( Figure 9A 、 Figure 9B and Figure 9C ) are for reference only (there may be slight deviations in practice), so please note this first.
[0061] The at least one liquid object 91 flows along the upper conical plate 112 and the upper opening 111 and is discharged from the upper discharge unit 30 .
[0062] [b] Second feature: The first space S1 is gradually narrowed from the inside to the outside and gradually moves downward, which helps the at least one liquid object 91 to be quickly discharged from the upper discharge unit 30 along the upper conical plate 112 and the upper opening 111.
[0063] [c] The third feature: There may be an offset distance D between the water inlet unit 20 and the upper opening 111 (in Figure 4 and Figure 6 For example), when the sewage 90 is supplied, the sewage 90 can flow in a vortex in the first space S1 in conjunction with the centrifugal force.
[0064] The advantages and effects of this utility model can be summarized as follows:
[0065] [1] Centrifugal separation is a convenient alternative to sedimentation separation. In this case, the centrifugal transmission unit is used to drive the sewage to centrifugal rotation to achieve solid-liquid separation, eliminating the time-consuming and inconvenient traditional sedimentation separation. Therefore, centrifugal separation is a convenient alternative to sedimentation separation.
[0066] [2] The first space facilitates rapid liquid drainage. The first space is tapered from the inside outward and gradually faces downward, with a cross-section similar to a bell mouth, which facilitates the liquid to quickly flow along the upper conical plate and out of the upper discharge unit from the upper opening. Therefore, the first space facilitates rapid liquid drainage.
[0067] [3] The longitudinal connection between the two spaces can coordinate gravity and centrifugal force to improve separation efficiency. The first space is connected to the second space through the longitudinal narrow connection portion, thereby forming a longitudinal connection design, so that the solid matter can be quickly thrown into the second space under the state of centrifugal force and gravity, and then discharged through the lower discharge unit. Therefore, the longitudinal connection between the two spaces can coordinate gravity and centrifugal force to improve separation efficiency.
[0068] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
