[0022] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0026] like Figure 1 As shown, this embodiment provides a lateral flow concentrating and screening device, including: a main body 1, which is a vertical round tank structure, a concentrating area 2 is arranged in the main body 1, and the bottom of the concentrating area 2 is a conical bottom to facilitate the aggregation of sludge.

[0027] The nozzle 3 and the throat 4 are both arranged in the condensation zone. One end of the nozzle 3 is connected to the external sewage source through the water inlet pipe 13, and the other end extends into the bottom of the throat 4, and a return port 14 is left between the two. The throat 4 can be arranged in the central area of ​​the condensation zone in the longitudinal direction. The top of the throat 4 does not contact the top of the body 1. The water enters the throat 4 after being accelerated by the nozzle 3, and then is released at the top of the throat 4 and diffuses to the surroundings. The diffused water falls under the action of its own weight. Among them, a part of the water flows back to the throat 4 through the return port 14 to participate in re-mixing, and the other part of the water is screened and concentrated by the sludge through the inclined plate separation component.

[0028] The cone plate separation assembly 5 is arranged in the concentration zone 2, and the cone plate separation assembly 5 includes a main body and a plurality of cone plates 6 arranged on the main body. The plurality of cone plates 6 are arranged in parallel and spaced from top to bottom, and each cone plate 6 is arranged obliquely downward, and the space between two adjacent cone plates 6 forms a separation channel 7. The water in the concentration zone 2 enters the separation channel 7 through the inlet end of the separation channel 7, and the sludge in the water flows down along the cone plates 6 to the bottom of the concentration zone 2 and finally gathers at the bottom of the concentration zone 2. The clean water in the water flows out of the concentration zone 2 through the outlet end of the separation channel 7.

[0029] When in use, when the water in the concentration area 2 passes through the uppermost separation channel 7, a part of the water can enter the separation channel 7 from the inlet end of the separation channel 7, and then a part of the clean water flows out from the outlet end of the separation channel 7. The sludge in the separation channel 7 slides down along the cone plate 6, mixes with the water from the concentration area 2, and then continues to move downward into the next separation channel 7. Each separation channel 7 can separate the sludge and clean water in the water. After the water passes through the multiple separation channels 7 of the cone plate separation assembly 5, it is equivalent to multi-stage screening and concentration, which finally separates the sludge and clean water in the water to achieve a concentration effect.

[0030] Among them, the cone plate located at the top layer in the cone plate separation assembly 5 is the first cone plate 8, and the outer edge of the first cone plate 8 is longer than the outer edges of the remaining cone plates 6. At this time, most of the water in the concentration area 2 sinks faster under the guidance of the first cone plate 8, and the remaining small part of the water goes over the first cone plate 8 and enters the separation channel 7 on the upper layer, while the water that sinks faster can enter the separation channel 7 downstream.

[0031] In the sludge thickening device provided in this embodiment, the cone plate 6 located at the top layer in the cone plate separation assembly 5 is the first cone plate 8, and the outer edge of the first cone plate 8 is longer than the outer edges of the other cone plates 6. The water in the thickening area 2 is accelerated to sink under the guidance of the first cone plate 8, which prevents the water from short-circuiting in several upstream separation channels 7, and can increase the water flow distributed to the downstream separation channel 7. Such an arrangement solves the problem of uneven water distribution along the vertical direction of the traditional cone plate separation assembly 5, so that the lower cone plate 6 can be fully utilized, which is conducive to improving the water treatment efficiency.

[0032] like Figure 1 As shown, in one embodiment, the main body of the cone plate separation assembly 5 is an annular member 9, which is arranged around the inner wall of the body 1, and the space between the annular member 9 and the inner wall of the body 1 forms an annular water collection bin 10. In this embodiment, the cone plate 6 is located in the space between the throat 4 and the annular member 9.

[0033] like Figure 2 As shown, in one embodiment, the main body of the cone plate separation assembly 5 is an annular member 9, which is arranged around the throat 4, and the space between the annular member 9 and the outer wall of the throat 4 forms an annular water collection bin 10. In this embodiment, the cone plate 6 is located in the space between the inner wall of the body 1 and the annular member 9.

[0034] The ring member 9 is provided with a water hole 11, and the water outlet of each separation channel 7 is connected to the water collection bin 10 through the water hole 11. For example, when producing the equipment, the size and density of the water hole 11 can be controlled to maintain a relatively high internal pressure in the concentration area 2 during later use. Driven by the pressure, the water in the concentration area 2 continuously enters the separation channel 7, and the clean water can enter the water collection bin 10.

[0035] Preferably, the water hole 11 is arranged near the cone plate 6 above the separation channel 7. In this way, the water hole 11 is arranged near the top of the separation channel 7, the bottom of the separation channel 7 is sludge, and the top is clean water. This can prevent the sludge from flowing through the water hole 11 into the water collection bin 10, thereby improving the water discharge effect.

[0036] Among them, the outer edges of the remaining cone plates 6 in the cone plate separation assembly 5, except for the first cone plate 8, are gradually shortened from top to bottom. At this time, from top to bottom, the interval between the outer edge of the cone plate 6 and the inner wall of the main body 1 gradually increases. Or, the interval between the outer edge of the cone plate 6 and the side wall of the throat 4 gradually increases. When in use, due to the separation effect of the upper separation channel 7, the sludge concentration in the lower separation channel 7 gradually increases, and the length of the lower cone plate 6 becomes smaller, so that the cross-section of the downward water flow space between the cone plate separation assembly 5 and the main body 1 can be continuously increased, and the water flow rate becomes smaller, which is conducive to the separation of mud and water of high-concentration water. Moreover, the increase in space also increases the ability to accommodate sludge, preventing sludge accumulation and blockage.

[0037] The sludge thickening device further includes a drain pipe 15 , one end of which is connected to the bottom of the water collecting bin 10 , and the other end of which extends to the outside of the body 1 , for draining the supernatant in the water collecting bin 10 .

[0038] The sludge concentrating device further includes a sludge discharge pipe 16 , one end of which is connected to the bottom of the concentrating area 2 , and the other end of which extends to the outside of the body 1 , for discharging the sludge in the concentrating area 2 .

[0039] Among them, the lateral flow concentration and screening device also includes a supernatant collecting pipe 12, one end of which is connected to the top of the water collecting bin 10, and the other end extends outward to the outside of the main body 1. The supernatant in the water collecting bin 10 is discharged from the main body 1 through the supernatant collecting pipe 12.

[0040] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
