They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.
[0031] 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.
[0032] 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.
[0033] like Figure 1 As shown, this embodiment provides a pressure-type mud and water concentration and purification device, including a main body 1, a central tube, a first ring-shaped member 2 and a filtering structure 3, wherein the central tube is arranged concentrically with the main body 1 in the main body 1, and the internal space of the central tube forms a sludge reaction zone 13 for sludge reaction; the first ring-shaped member 2 is arranged concentrically with the main body 1 in the main body 1, and the first ring-shaped member 2 is located on the outside of the central tube; the area between the first ring-shaped member 2 and the inner wall of the main body 1 forms a sedimentation area 11; the area between the inner wall of the first ring-shaped member 2 and the outer wall of the central tube forms a mud and sand settling area 12; the mud and sand settling area 13 is formed by the inner wall of the first ring-shaped member 2 and the outer wall of the central tube. The inlet of the sedimentation zone 12 is connected to an external sewage source, the water outlet of the sedimentation zone 12 is connected to the inlet of the sludge reaction zone 13, and the sand outlet of the sedimentation zone 12 is connected to the outside of the main body 1; the outlet of the sludge reaction zone 13 is connected to the inlet of the sedimentation zone 11; one end of the filter structure 3 is connected to the sedimentation zone 12, and the other end is connected to the sludge reaction zone 13; the filter structure 3 is suitable for filtering the sediment in the water; after the external sewage enters the sedimentation zone 12, the sediment in the water settles into the sedimentation zone 12, and the water after the sand is removed enters the sludge reaction zone 13.
[0034] Furthermore, the part of the filter structure 3 located in the mud and sand settling area 12 is a cone-shaped structure, and the water body enters the sludge reaction area 13 along the side wall of the filter structure 3. It should be noted that the filter structure 3 is inverted on the top of the mud and sand settling area 12, and the cross-sectional area of the filter structure 3 gradually decreases along the flow direction of the water body. In the process of rising, the water body will first contact the filter structure 3, and after the mud and sand in the water body touches the filter structure 3, part of the mud and sand will gather on the inner wall of the filter structure 3, and slide along the inner wall of the filter structure 3 to the bottom of the mud and sand settling area 12, and because the cross-sectional area of the filter structure 3 gradually decreases, only the water body is allowed to pass through, and impurities such as mud and sand cannot pass through the filter structure 3, ensuring that the mud and sand in the water body will not pass through the filter structure 3.
[0035] Furthermore, the first annular member 2 is in a cone-shaped structure as a whole, so that after the water enters the mud and sand settling area 12, the sand in the water can slide along the inner wall of the first annular member 2 to the bottom of the mud and sand settling area 12. It should be noted that a maintenance window is also provided on the side wall of the first annular member 2, through which the interior of the first annular member 2 can be repaired later.
[0036] Furthermore, a water body ejector is included, the sewage source outside the water body ejector is connected, the outlet of the water inlet ejector 4 faces the filter structure 3; the water passing through the water inlet ejector 4 will flow through the filter structure 3. It should be noted that the water body ejector can drive the water to move toward the filter structure 3.
[0037] It should be noted that the water ejector is connected to an external sewage source via a pipeline.
[0038] It should be noted that the sludge sedimentation area 11 contains sludge floc particles for the growth of anaerobic microorganisms, and the water body is anaerobically treated and purified under the action of anaerobic microorganisms. The sludge floc particles will gather and form larger sludge particles and settle under the action of weight.
[0039] It should be noted that in this embodiment, a dosing pipe is also provided, which is connected to the water acceleration device and is used to inject anaerobic microorganisms and the like.
[0040] Furthermore, a sand discharge pipe 5 is provided, one end of which is connected to the bottom of the mud and sand settling area 12, and the other end of which extends to the outside of the main body 1; when there is too much mud and sand in the mud and sand settling area 12, the sand discharge pipe 5 can be opened manually to discharge the excess mud and sand to prevent the mud and sand settling area 12 from being blocked.
[0041] Furthermore, it also includes a second annular member 6 and a mud discharge pipe 7, wherein the second annular member 6 is arranged concentrically with the main body 1 in the main body 1, and the second annular member 6, the first annular member 2 and the main body 1 together enclose the sedimentation area 11; one end of the mud discharge pipe 7 extends into the bottom of the sedimentation area 11, and the other end extends to the outside of the main body 1. It should be noted that the third annular member as a whole also has a cone-shaped structure, and the mud in the water body can slide along the inner wall of the third annular member to the bottom of the sedimentation area 11. A maintenance window is also provided on the side wall of the second annular member 6.
[0042] Furthermore, it also includes a throat pipe 8, which is arranged concentrically with the central tube in the central tube, and the area between the throat pipe 8 and the central tube forms a sludge reaction zone 13.
[0043] Furthermore, it also includes a baffle channel 9, which is arranged between the sludge reaction area 13 and the mud and sand settling area 12;
[0044] The outlet of the sludge reaction zone 13 is connected to the inlet of the baffle channel 9. The outlet of the baffle channel 9 is divided into a first branch and a second branch. The water along the first branch flows back to the throat 8, and the water along the second branch enters the mud and sand settling zone 12.
[0045] A plurality of mud guards are also provided in the mud and sand settling area 12. The mud guards are provided on the inner wall of the first annular member 2. As the water body moves over time, the water level gradually rises. When the water body passes through the mud guards, the mud in the water body will be blocked by the mud guards, thereby achieving further filtration.
[0046] Furthermore, an inclined tube separation device 10 and a water outlet trough 101 are provided in the sedimentation area 11, and the inclined tube separation device 10 is located upstream of the water outlet trough 101;
[0047] The water in the sedimentation area 11 enters the water outlet trough 101 after sedimentation and separation by the inclined tube separation device 10 , and then is discharged from the main body 1 through the water outlet trough 101 .
[0048] It should be noted that the function of the inclined tube separation device 104 is to form multiple channels, through which the fine particles in the water body can be precipitated to increase the cleanliness of the water body. It should be noted that the existing market concentration is not integrated, but simply concentrated, and the supernatant is returned to the original system for further treatment, and there is no sand separation effect. This equipment concentrates and treats together, the supernatant is clear, and the sludge enters the concentration section to the greatest extent, and no longer returns to the original system for further treatment.
[0049] 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.
