[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0028] The following is combined Figure 1 This invention describes a manure hydrocyclone solid-liquid separator.
[0029] like Figure 1 As shown, this utility model provides a manure cyclone solid-liquid separator 1, comprising: a separator body 11, within which a cyclone cavity 111 is formed. The cyclone cavity 111 includes a cylindrical guide cavity 112 and a conical guide cavity 113 that are interconnected. The cylindrical guide cavity 112 is located above the conical guide cavity 113. A tangentially extending inlet 114 is provided on the side wall of the cylindrical guide cavity 112, and an overflow port 115 is provided at the top of the cylindrical guide cavity 112. The cone tip of the conical guide cavity 113 is oriented downwards, and a bottom outlet 116 is provided at the cone tip. The ratio of the length to the diameter of the cylindrical guide cavity 112 is not less than 1.5 and not greater than 1.6.
[0030] In the embodiment, the cyclone cavity 111 is divided into the cylindrical flow guide cavity 112 and the conical flow guide cavity 113 arranged in an up-down manner, and the feed inlet 114 extending along the tangential direction of the cylinder is arranged on the side wall of the cylindrical flow guide cavity 112, so that the liquid manure to be separated is introduced from the feed inlet 114 and enters the cylindrical flow guide cavity 112 in a tangential direction, and the liquid manure forms a cyclone along the side wall of the cylindrical flow guide cavity 112, and the solid and liquid in the liquid manure can be preliminarily separated in a solid-liquid manner under the action of centrifugal force and density difference. The bottom of the cylindrical flow guide cavity 112 is provided with the conical flow guide cavity 113 with a conical tip downward, and the tangential velocity of the cyclone liquid rapidly increases under the influence of the side wall of the conical cavity after the cyclone liquid enters the conical flow guide cavity 113, so as to strengthen the centrifugal effect, so that the relatively heavy solid is concentrated near the side wall of the cavity, and a larger negative pressure area is formed at the central axis position of the cyclone cavity 111, so that the liquid part can stay in the cyclone cavity 111 for a longer time, so as to better separate the solid and the liquid part. The solid part and part of the liquid are discharged from the bottom outlet 116 at the bottom of the conical flow guide cavity 113, and the separated liquid with small density is discharged from the overflow port 115 at the top of the cylindrical flow guide cavity 112, so as to be subjected to subsequent mechanical manure fertilization.
[0031] Meanwhile, by limiting the ratio of the length to the diameter of the cylindrical flow guide cavity 112 to be between 1.5 and 1.6, the separation capacity of the manure cyclone type solid-liquid separator 1 for fine particle solid in the liquid manure can be effectively improved, and the separated manure water can better meet the needs of mechanical fertilization.
[0032] The manure cyclone type solid-liquid separator 1 of the utility model, by setting the cylindrical flow guide cavity 112 and the conical flow guide cavity 113 arranged in an up-down manner and communicated in the separator body 11, and setting the feed inlet 114 extending along the tangential direction on the side wall of the cylindrical flow guide cavity 112, so that the liquid manure to be separated enters from the feed inlet 114 and forms a cyclone liquid in the cylindrical flow guide cavity 112, and the liquid and the solid in the liquid manure are preliminarily separated under the action of centrifugal force and density difference, after the cyclone liquid enters the conical flow guide cavity 113, the tangential velocity of the cyclone liquid increases, so that the liquid and the solid are further separated, wherein part of the liquid and the solid are discharged from the bottom outlet 116 of the conical flow guide cavity 113, and the remaining part of the liquid overflows from the overflow port 115 at the top of the cylindrical flow guide cavity 112, so as to be collected and used for mechanical manure fertilization. Meanwhile, by limiting the ratio of the length to the diameter of the cylindrical flow guide cavity 112 to be between 1.5 and 1.6, the separation capacity of the manure cyclone type solid-liquid separator 1 for fine particle solid in the liquid manure can be improved.
[0033] As can be seen, the manure rotary flow type solid-liquid separator 1 can effectively separate the fine solid particles in the liquid manure, and can collect the separated liquid part through the overflow port 115 for manure mechanical fertilization, effectively solving the defects of high solid content in the manure, easy to block and affecting manure mechanical fertilization in the prior art.
[0034] It can be understood that the shape of the feed port 114 has a great influence on the separation performance and energy loss of the manure rotary flow type solid-liquid separator 1, and the diameter of the feed port 114 needs to be determined according to the processing capacity and the size requirements of the connecting pipe.
[0035] Specifically, in some embodiments, the length of the cylindrical flow guide cavity 112 is 560mm, and the diameter is 350mm. In this embodiment, by designing the specific size of the cylindrical flow guide cavity 112, the cylindrical flow guide cavity 112 can better separate the fine solid particles with a particle size of 120 mesh (125μm) and below, so that the separated liquid part can better meet the requirements of manure mechanical fertilization.
[0036] In some embodiments, as shown in Figure 1 The manure rotary flow type solid-liquid separator 1 further comprises an overflow pipe 12, which is arranged at the top of the separator body 11, and the overflow pipe 12 and the overflow port 115 are in communication.
[0037] In this embodiment, by arranging the overflow pipe 12 at the top of the separator body 11 and the overflow port 115, the overflow pipe 12 can prevent the separated liquid from flowing out directly from the overflow port 115, and the overflow pipe 12 can be conveniently connected with the external pipeline to pass the separated liquid into other equipment (such as a fertilization machine).
[0038] Specifically, in some embodiments, as shown in Figure 1 The bottom end of the overflow pipe 12 extends into the interior of the cylindrical flow guide cavity 112.
[0039] In this embodiment, the overflow pipe 12 is inserted into the overflow port 115, and the bottom end thereof extends into the interior of the cylindrical flow guide cavity 112 through the overflow port 115, so that the overflow pipe 12 can guide the separated overflow liquid to move upward.
[0040] In some embodiments, the height of the bottom end of the overflow pipe 12 is lower than the height of the bottom of the feed port 114. In this embodiment, by extending the bottom end of the overflow pipe 12 to a position lower than the bottom of the feed port 114, the separated liquid can be better guided to flow out through the overflow pipe 12.
[0041] Specifically, in some embodiments, as shown inFigure 1 As shown, the overflow pipe 12 is located on the central axis of the cylindrical flow guide cavity 112, so that the separated liquid rises along the central axis through the overflow pipe 12, reducing the mutual influence between the overflow and the cyclone liquid.
[0042] Further, in some embodiments, the ratio of the length of the part of the overflow pipe 12 located in the cylindrical flow guide cavity 112 to the diameter of the cylindrical flow guide cavity 112 is not less than 0.2 and not greater than 1. In this embodiment, by limiting the ratio of the length of the part of the overflow pipe 12 located in the cylindrical flow guide cavity 112 to the diameter of the cylindrical flow guide cavity 112, the overflow pipe 12 can better guide the upward overflow of the separated liquid part, while reducing the influence of the overflow pipe 12 itself on the flow field in the cylindrical flow guide cavity 112 and the separation efficiency.
[0043] Specifically, in some embodiments, the length of the part of the overflow pipe 12 located in the cylindrical flow guide cavity 112 is 210 mm.
[0044] Specifically, in some embodiments, the taper angle of the tapered flow guide cavity 113 is not less than 20° and not greater than 45°. In this embodiment, by limiting the taper angle of the tapered flow guide cavity 113 to between 20° and 45°, the tapered flow guide cavity 113 can better separate the coarse particle solid.
[0045] Specifically, in some embodiments, the taper angle of the tapered flow guide cavity 113 is 27.53°. The length of the tapered flow guide cavity 113 is 633 mm.
[0046] Specifically, the diameter of the bottom outlet 116 is not less than 40 mm.
[0047] In this embodiment, by setting the diameter of the bottom outlet 116 to be not less than 40 mm, it is avoided that the solid separated in the cyclone cavity 111 is accumulated and blocked at the bottom outlet 116, affecting the separation efficiency and processing capacity of the manure cyclone type solid-liquid separator 1.
[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacements for some technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
