Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] 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.

[0031] like Figure 1As shown, this embodiment provides a side-flow rapid purification device, including: a body 1, which is a vertical tank-shaped structure, for example, the body 1 is a vertical round tank structure. A sedimentation zone is arranged in the body 1, and the sedimentation zone is divided into an upper half and a lower half, and the water body can flow from the upper half 2 of the sedimentation zone to the lower half 3 of the sedimentation zone. The cone plate separation assembly 4 is arranged in the lower half 3 of the sedimentation zone, and the cone plate separation assembly 4 includes a plurality of cone plates 5 arranged in parallel and spaced from top to bottom, and each cone plate 5 is arranged obliquely downward, and the space between two adjacent cone plates 5 above and below forms a separation channel 6. The water body in the lower half 3 of the sedimentation zone enters the separation channel 6 through the inlet end of the separation channel 6, and the sludge in the water body slides down the cone plate 5 and flows to the bottom of the sedimentation zone, and the clean water in the water body flows out of the sedimentation zone through the outlet end of the separation channel 6. When in use, when the water in the lower half 3 of the sedimentation zone passes through the uppermost separation channel 6, a portion of the water can enter the separation channel 6 from the inlet end of the separation channel 6, and then a portion of the clean water flows out from the outlet end of the separation channel 6. The sludge in the separation channel 6 slides down along the cone plate 5, mixes with the water from the lower half 3 of the sedimentation zone, and then continues to move downward into the next separation channel 6. Each separation channel 6 can separate the sludge and clean water in the water. After the water passes through multiple separation channels 6 of the cone plate separation assembly 4, it is equivalent to multi-stage sedimentation separation, and finally the separation of sludge and clean water in the water is achieved.

[0032] Among them, the cone plate located at the top layer in the cone plate separation assembly 4 is the first cone plate 7, and the outer edge of the first cone plate 7 is longer than the outer edges of the remaining cone plates 5. At this time, most of the water in the lower half area 3 of the sedimentation area is accelerated to sink under the guidance of the first cone plate 7, and the remaining small part of the water passes over the first cone plate 7 and enters the separation channel 6 on the upper layer, while the water that is accelerated to sink can enter the separation channel 6 downstream.

[0033] In the side-flow rapid purification device provided in this embodiment, the cone plate 5 located at the top layer in the cone plate separation assembly 4 is the first cone plate 7, and the outer edge of the first cone plate 7 is longer than the outer edges of the other cone plates 5. The water in the lower half area 3 of the sedimentation area is accelerated to sink under the guidance of the first cone plate 7, which prevents the water from short-circuiting in several upstream separation channels 6, and can increase the water flow distributed to the downstream separation channel 6. Such an arrangement solves the problem of uneven water distribution along the vertical direction of the traditional cone plate separation assembly 4, so that the lower cone plate 5 can be fully utilized, which is conducive to improving the water treatment efficiency.

[0034] Specifically, the side-flow rapid purification device also includes a first ring member 8 and a second ring member 9; for example, the first ring member 8 and the second ring member 9 are both ring plates, the first ring member 8 and the second ring member 9 are concentrically arranged in the main body 1, and the first ring member 8 is located in the inner circle, the inner circle space of the first ring member 8 forms an annular mixing reaction zone 12, the space between the first ring member 8 and the second ring member 9 forms an annular sludge suspension zone 13, and the space between the outer wall of the second ring member 9 and the inner wall of the main body 1 forms an annular sedimentation zone.

[0035] Among them, for the mixed reaction zone 12, a throat 14 and a nozzle 15 are arranged therein, and the nozzle 15 can have multiple levels, and the multiple levels of nozzles 15 are nested and used to improve the acceleration effect on the water body. The inlet of the nozzle 15 is connected to the external water source through the water inlet pipe 17, and the outlet of the nozzle 15 extends into the throat 14. The top of the throat 14 does not contact the top of the body 1, and a return water port is left between the bottom of the throat 14 and the nozzle 15. When in use, the external water enters the throat 14 through the water inlet pipe 17 and the nozzle 15, and the water in the throat 14 is released at the top and diffuses and falls around. A part of the water can re-enter the throat 14 from the return water port, and the rest of the water will be transported to the sludge suspension area 13.

[0036] Among them, for the sludge suspension zone 13, after the water flowing out of the mixed reaction zone 12 enters the sludge suspension zone 13, a filter bed composed of suspended sludge can be formed in the sludge suspension zone 13, and the water can be filtered and purified when passing through the filter bed. A reflux channel 16 is also provided in the sludge suspension zone 13, and part of the water in the sludge suspension zone 13 can flow back to the nozzle 15 or the throat 14 through the reflux channel 16, and finally flow back to the mixed reaction zone 12.

[0037] Among them, for the sedimentation zone, the water in the sludge suspension zone 13 first enters the upper half 2 of the sedimentation zone, and then the water moves downward into the lower half 3 of the sedimentation zone, and the sludge in the water is precipitated and separated by the cone plate separation component 4 to obtain clean water.

[0038] In one embodiment, the side-flow rapid purification device further comprises a water outlet bin and a third annular member 10; the water outlet bin is arranged on the side of the second annular member facing away from the first annular member and is located at the bottom of the second annular member;

[0039] The third annular member is arranged on the inner wall of the water storage bin, and the space between the third annular member 10 and the water outlet bin 23 forms a water collection bin 11; the cone plate separation assembly 4 is arranged on the outer wall of the water outlet bin 23, and the outlet end of each separation channel 6 is connected to the water collection bin 11. The sludge sediment in the water body is separated by the cone plate separation assembly 4 to obtain clean water, and the clean water enters the water collection bin 11. When the water in the water collection bin 11 reaches a certain amount, it overflows into the water outlet bin 23, wherein a second water outlet pipe 25 can be arranged at the bottom of the water outlet bin 23, and the second water outlet pipe 25 is used for draining or emptying the water outlet bin 23.

[0040] like Figure 2 As shown, a first water hole 22 is provided on the side wall of the water outlet bin 23, and the water outlet end of each separation channel 6 is connected to the water collection bin 11 through the first water hole 22. For example, when producing the equipment, the size and density of the first water hole 22 can be controlled to maintain a relatively high internal pressure in the sedimentation area during later use. Driven by the pressure, the water in the sedimentation area continuously enters the separation channel 6, and the clean water can enter the water collection bin 11.

[0041] Preferably, the first water hole 22 is arranged near the cone plate 5 above the separation channel 6. In this way, the first water hole 22 is arranged near the top of the separation channel 6, the bottom of the separation channel 6 is sludge, and the top is clean water. This can prevent the sludge from flowing into the water collection bin 11 through the first water hole 22, thereby improving the water discharge effect.

[0042] like Figure 3 As shown, the outer edges of the remaining cone plates 5 in the cone plate separation assembly 4, except for the first cone plate 7, gradually shorten from top to bottom. At this time, from top to bottom, the interval between the outer edge of the cone plate 5 and the inner wall of the body 1 gradually increases. When in use, due to the separation effect of the upper separation channel 6, the sludge concentration in the lower separation channel 6 gradually increases, and the length of the lower cone plate 5 becomes smaller, so that the cross-section of the downward water flow space between the cone plate separation assembly 4 and the 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.

[0043] like Figure 4 As shown, in one embodiment, the side-flow rapid purification device further includes a third annular member 10, which is arranged on the inner side wall of the body 1, and the space between the inner side of the third annular member 10 and the body 1 forms an annular water collection bin 11; the cone plate separation assembly 4 is arranged on the outer side of the third annular member 10, and the outlet end of each separation channel 6 is connected to the water collection bin 11. The sludge sediment in the water body is separated by the cone plate separation assembly 4 to obtain clean water, and the clean water enters the water collection bin 11. Among them, a first water outlet pipe 18 can be arranged on the top of the water collection bin, and the water in the water collection bin 11 can be discharged through the first water outlet pipe 18.

[0044] like Figure 5 As shown, the third annular member 10 is provided with a second water hole 24, and the water outlet of each separation channel 6 is connected to the water collection bin 11 through the second water hole 24. For example, the size and density of the second water hole 24 can be controlled to maintain a relatively high internal pressure in the sedimentation area. Driven by the pressure, the water in the sedimentation area continuously enters the separation channel 6, and the clean water can enter the water collection bin 11.

[0045] Preferably, the second water hole 24 is arranged near the cone plate 5 above the separation channel 6. In this way, the second water hole 24 is arranged near the top of the separation channel 6, the bottom of the separation channel 6 is sludge, and the top is clean water. The sludge can be prevented from flowing into the water collection bin 11 through the second water hole 24, thereby improving the water discharge effect.

[0046] Among them, the outer edges of the remaining cone plates 5 in the cone plate separation assembly 4, except for the first cone plate 7, are gradually shortened from top to bottom. When in use, due to the separation effect of the upper separation channel 6, the sludge concentration in the lower separation channel 6 gradually increases, and the length of the lower cone plate 5 becomes smaller, so that the cross-section of the water flow space on the side of the cone plate separation assembly 4 away from the third annular member 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. In addition, the increase in space also increases the ability to accommodate sludge, preventing sludge accumulation from causing blockage.

[0047] A drain pipe 19 is also provided in the sedimentation area. One end of the drain pipe 19 is connected to the bottom of the sedimentation area, and the other end extends to the outside of the body 1 for draining the sludge in the sedimentation area.

[0048] A sludge discharge pipe 21 is also provided in the sedimentation area. One end of the sludge discharge pipe 21 is connected to the bottom of the sedimentation area, and the other end extends to the outside of the body 1 for discharging the sludge in the sedimentation area.

[0049] A sludge discharge pipe 21 is also provided in the sludge suspension area 13 , one end of the sludge discharge pipe 21 is connected to the bottom of the sludge suspension area 13 , and the other end of the sludge discharge pipe 21 extends to the outside of the body 1 for discharging sludge in the sludge suspension area 13 .

[0050] A sludge return pipe 20 is also provided in the sedimentation zone. One end of the sludge return pipe 20 is connected to the nozzle 15 , and the other end is connected to the sedimentation zone, so as to return the sludge in the sedimentation zone to the mixing reaction zone 12 .

[0051] 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.
