[0005] To achieve the above objectives, in a first aspect, this application provides a settling tank, comprising:

[0006] The sedimentation tank body includes a first drain pipe and a second drain pipe. The first drain pipe is used to discharge water containing solid waste into the sedimentation tank body, and the second drain pipe is connected to a sewage pipe downstream of the sedimentation tank body to discharge clean water from the sedimentation tank body.

[0007] A flushing assembly is installed at the inlet of the second drain pipe. The flushing assembly is used to release the blockage of the inlet when the water volume in the sedimentation tank body reaches a preset water volume, so that the water in the sedimentation tank body flushes the sewage pipe.

[0009] The hollow sealing cover is installed on the inlet and is used to seal the inlet. The hollow sealing cover includes a cover body and a protrusion protruding from the plane of the cover body. The protrusion corresponds to the position of the inlet and includes a cavity communicating with the inlet. The first position of the hollow sealing cover is hinged to the second drain pipe.

[0010] The float is connected to the second position of the hollow sealing cover. The float can float under the buoyancy of the water. The float is used to apply a pulling force to the hollow sealing cover so that the water volume in the sedimentation tank body reaches a preset water volume. The float pulls the hollow sealing cover to open.

[0011] The first position is any position circumferentially of the hollow sealing cover, and the second position is offset from the first position.

[0012] Preferably, in the aforementioned settling tank, the float is connected to the hollow sealing cover by at least one of a rope and a hinge.

[0013] Preferably, in the above-mentioned settling tank, the hollow sealing cover is a rubber cover; and / or,

[0014] The float can be a PP float, a PVC float, a PTFE float, or a stainless steel float.

[0015] Preferably, in the above-mentioned settling tank, the bottom of the settling tank body is provided with a settling slope, and the settling slope includes a channel for installing the second drain pipe;

[0016] The channel is located in the lower middle part of the slope in the direction of inclination of the settlement slope, and the first drainage pipe corresponds to the higher end of the settlement slope.

[0017] Preferably, in the aforementioned settling tank, the inlet of the second drain pipe does not exceed the height of the higher end of the settling slope.

[0018] Preferably, the sedimentation tank also includes a spiral sludge discharge mechanism for discharging solid waste located at the lower end of the sedimentation slope.

[0021] Secondly, this application discloses a water treatment system, including a sedimentation tank, wherein the sedimentation tank is the sedimentation tank described in any of the above embodiments.

[0022] The sedimentation tank provided in this application embodiment includes a sedimentation tank body and a flushing component. The sedimentation tank body includes a first drain pipe and a second drain pipe. The flushing component is disposed at the inlet of the second drain pipe. When the water volume in the sedimentation tank body reaches a preset water volume, the flushing component releases the blockage of the inlet, and a large amount of water concentrates and rushes into the second drain pipe and the sewage pipe at high speed. The rushing water generates a large impact force on the solid waste in the second drain pipe and the sewage pipe, flushing the second drain pipe and the sewage pipe, and carrying away the solid waste attached to the second drain pipe and the sewage pipe, reducing the risk of sewage pipe blockage.

[0023] This application also discloses a water treatment system, including a sedimentation tank, which is the sedimentation tank described in any of the above embodiments.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0036] In related technologies, the pipeline used to discharge clean water in the sedimentation tank body is always connected to the sedimentation tank, and the water in the sedimentation tank is continuously discharged through the pipeline; the pipeline that supplies sewage to the sedimentation tank also continuously supplies sewage into the sedimentation tank, which inevitably leads to the discharge of clean water carrying solid waste from the sewage, resulting in a high risk of blockage of the sewage pipe connected to the pipeline that discharges clean water.

[0037] Firstly, such as Figure 1 The diagram shown is a structural schematic of the settling tank disclosed in an embodiment of this application. The settling tank includes a settling tank body 1 and a flushing assembly 4.

[0038] The sedimentation tank body 1 includes a first drain pipe 2 and a second drain pipe 3. The first drain pipe 2 is used to discharge water containing solid waste into the sedimentation tank body 1. The solid waste settles in the sedimentation tank body, forming a clear water layer on top and a waste layer on the bottom. The second drain pipe 3 is connected to the sewage pipe downstream of the sedimentation tank, and the clear water in the sedimentation tank body 1 is discharged through the second drain pipe 3.

[0039] The flushing component 4 is installed at the inlet of the second drain pipe 3, and the outlet of the second drain pipe 3 is connected to the sewage pipe. The flushing component 4 is used to release the blockage of the inlet when the water volume of the sedimentation body reaches the preset water volume, so that the water in the sedimentation tank can flush the sewage pipe.

[0040] Specifically, before the water volume in the settling body reaches the preset water volume, the flushing component 4 blocks the inlet of the second drain pipe 3, so there is no water in the second drain pipe 3; only when the water volume in the settling body reaches the preset water volume will the flushing component 4 release the blockage of the inlet of the second drain pipe 3. At this time, a large amount of water concentrates and rushes into the second drain pipe 3 and the sewage pipe at high speed. The rushing water generates a large impact force on the solid waste in the second drain pipe 3 and the sewage pipe, flushing the second drain pipe 3 and the sewage pipe, carrying away the solid waste attached to the second drain pipe 3 and the sewage pipe, and reducing the risk of sewage pipe blockage.

[0041] In some embodiments, the flushing assembly 4 includes a hollow sealing cap 41 and a float 42.

[0042] Hollow sealing cover 41 is installed at the inlet and is used to seal the inlet. The first position of hollow sealing cover 41 is hinged to the second drain pipe 3. Float ball 42 can float under the buoyancy of the water in the sedimentation tank body 1. Float ball 42 is used to apply an upward pulling force to hollow sealing cover 41 so that when the water volume in the sedimentation tank body 1 reaches the preset water volume, float ball 42 pulls hollow sealing cover 41 to open.

[0043] During the drainage process, the hollow sealing cover 41 remains open under the action of water buoyancy, discharging the water accumulated in the sedimentation tank body 1. When the water level in the sedimentation tank body 1 drops to the upper edge of the second drain pipe 3, the hollow sealing cover 41 is closed back onto the inlet, blocking the inlet of the second drain pipe 3, and the sedimentation tank body 1 continues to accumulate water.

[0044] As the water volume in the sedimentation tank increases, the water level rises, and the water gradually submerges the float. Once the float 42 is completely submerged, the pulling force exerted by the float 42 on the hollow sealing cover 41 reaches its maximum. This pulling force is the difference between the buoyancy of the float 42 and its weight. In this embodiment, the preset water volume is at least sufficient to completely submerge the float 42.

[0045] like Figure 2 As shown, the hollow sealing cover 41 includes a cover body and a protrusion. The cover body has a flat plate structure, and the protrusion protrudes from the plane of the cover body. After the hollow sealing cover 41 is fitted with the inlet, the protrusion of the hollow sealing cover 41 corresponds to the position of the inlet, and the protrusion includes a cavity communicating with the inlet.

[0046] It should be noted that the first position of the hollow sealing cover 41 can be any position circumferentially around the hollow sealing cover 41, and the second position where the float 42 connects to the hollow sealing cover 41 is offset from the first position. Optionally, the connection position between the float 42 and the hollow sealing cover 41 can be the second position circumferentially around the hollow sealing cover 41, and the second position is offset from the first position circumferentially around the hollow sealing cover 41; the second position can be opposite to the first position.

[0047] Optionally, the float 42 is connected to the inlet portion of the hollow sealing cover 41, and the connection point can be located at the center of the hollow sealing cover 41. For example... Figure 3 As shown, the first position is one of the circumferential positions of the cover, and the second position is one of the circumferential positions of the protrusion.

[0048] The first position of the hollow sealing cover 41 is hinged to the second drain pipe 3. After the hollow sealing cover 41 is opened, it will not separate from the second drain pipe 3. After the water level in the sedimentation tank drops, the hollow sealing cover 41 can fall back to the inlet of the second drain pipe 3 under the combined action of water pressure and gravity, ensuring that the hollow sealing cover 41 can reseal the inlet and improve the reliability of the hollow sealing cover 41 in sealing the inlet.

[0049] The flushing assembly 4 disclosed in this application is a combination of mechanical structures that can be used repeatedly, thereby improving the reliability of the flushing assembly 4 in sealing the inlet and unsealing the inlet.

[0050] The flushing component 4 is not limited to the above embodiments. The flushing component 4 can also be a solenoid valve structure or other structures that can achieve intermittent communication between the second drain pipe 3 and the sedimentation tank body, all of which are within the protection scope of this application.

[0051] The number of floats 42 can be one or at least two. When there is only one float 42, the volume of the float 42 is relatively large; when there are at least two floats 42, the reliability of the floats lifting the hollow sealing cover 41 is increased, and the volume of a single float 42 can be relatively reduced.

[0052] When there are at least two floats 42, at least two floats 42 can share a connector (the connector is a component used to connect the floats 42 to the hollow sealing cover 41) to connect to the hollow sealing cover 41, so as to reduce the number of connection positions between the hollow sealing cover 41 and the connector. Alternatively, at least two floats 42 can be connected to the hollow sealing cover 41 through their respective connectors, and the seals corresponding to the at least two floats 42 are distributed in the circumferential direction of the hollow sealing cover 41 or on the plane of the corresponding inlet of the hollow sealing cover 41.

[0053] Optionally, the hollow sealing cover 41 and the float 42 are connected by at least one of a rope and a hinge. The connector creates a distance between the hollow sealing cover 41 and the float 42, reducing the influence of the float 42 on the opening of the hollow sealing cover 41.

[0054] Alternatively, the float 42 and the hollow sealing cap 41 can also be connected by direct welding.

[0055] The hollow sealing cap 41 can be a rubber cap. The rubber cap has a certain degree of flexibility, and the hollow sealing cap 41 can ensure the sealing effect on the inlet even after repeated opening and closing.

[0056] The hollow sealing cover 41 can also be a plastic cover or a metal cover, etc. The part of the plastic cover that fits with the pipe wall of the second drain pipe 3 is provided with a sealing gasket to ensure the sealing effect of the hollow sealing cover 41 on the inlet.

[0057] The hollow sealing cap 41 can be a cap structure adapted to the shape of the second drain pipe 3. Optionally, the part of the hollow sealing cap 41 corresponding to the cavity of the second drain pipe 3 is a hollow structure, or the part of the hollow sealing cap 41 corresponding to the cavity of the second drain pipe 3 has a plug structure adapted to the shape of the cavity.

[0058] The hollow sealing cap 41 is not limited to the above structure. Other structures that can achieve inlet sealing and can be opened under the pulling force of the float 42 are also within the scope of protection of this application.

[0059] The bottom of the sedimentation tank body 1 includes a sedimentation slope 11, which includes a channel for installing the second drainage pipe 3.

[0060] like Figure 1 As shown, the settling slope 11 extends from the first end of the settling tank to the second end of the settling tank, where the first end and the second end are opposite ends of the settling tank body 1. Optionally, the height of the settling slope 11 at the first end of the settling tank is greater than the height of the settling slope 11 at the second end of the settling tank.

[0061] The slope of settlement slope 11 is a flat plane.

[0062] The first drainage pipe 2 can be installed on the side wall of the sedimentation tank body 1 or at the opening of the sedimentation tank body 1. The first drainage pipe 2 and the second drainage pipe 3 are staggered in the inclination direction of the sedimentation slope 11.

[0063] Optionally, the first drain pipe 2 corresponds to the first end of the settling slope 11 with a higher height. The sewage discharged to the settling tank body 1 through the first drain pipe 2 falls at the first end of the settling slope 11, and solid waste rolls along the settling slope 11 and eventually accumulates at the end of the settling slope 11 with a lower height, which facilitates the treatment of solid waste in the settling tank.

[0064] The channel for installing the second drainage pipe 3 on the settlement slope 11 is located in the middle of the slope direction of the settlement slope 11. On the one hand, it can reduce the requirement for the preset water volume, and on the other hand, it can prevent the accumulation of solid dirt from affecting the opening of the hollow sealing cover 41.

[0065] The height of the inlet of the second drainage pipe 3 shall not exceed the height of the higher end of the settlement slope 11.

[0066] Optionally, a spiral sludge discharge mechanism 5 is provided inside the sedimentation tank body 1. The spiral sludge discharge mechanism 5 is used to discharge solid waste located at the lower end of the sedimentation slope 11.

[0067] In some embodiments, the spiral sludge discharge mechanism 5 includes a spiral conveyor 51 and a sludge collection box 52. The spiral conveyor 51 is arranged along the inclined direction of the settling slope 11 and transports solid sludge upward to the sludge collection box 52.

[0068] In some embodiments, the screw conveyor 51 of the screw sludge discharge mechanism 5 is located on one side of the sedimentation tank body 1 and corresponds to the end of the sedimentation tank body 1 with a lower height. The screw conveyor 51 horizontally discharges the solid sludge.

[0069] The first drain pipe 2 and the second drain pipe 3 are made of PVC pipe or stainless steel pipe, etc.

[0070] The first drain pipe 2 and the second drain pipe 3 are not limited to the materials mentioned above; other corrosion-resistant and high-strength materials are also suitable for this solution.

[0071] The float 42 is made of polypropylene (PP), polyvinyl chloride (PVC), polytetrafluoroethylene (PTFE), or stainless steel.

[0072] Secondly, this application also discloses a water treatment system, including a sedimentation tank, which is the sedimentation tank described in any of the above embodiments.

[0073] Since the sedimentation tank has the above-mentioned technical effects, the water treatment system with the sedimentation tank also has the same technical effects, which will not be elaborated here.

[0074] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed, and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. The scope of this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described application concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
