DETAILED DESCRIPTION

[0025] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0026] The sewage sediment separation and discharge device of the embodiment of the present application can be used to separate and discharge industrial sewage or domestic sewage after sedimentation, for example, for sewage purification treatment in sewage treatment plants.

[0027] The sewage sediment separation and discharge device according to an embodiment of the present application will be described below with reference to the accompanying drawings.

[0028] like Figure 1 and Figure 2 As shown, the sewage sediment separation and discharge device of the embodiment of the present application includes a sedimentation tank 1, a sediment pretreatment component 3 and a drainage component 4.

[0029] Among them, support legs 5 are provided at the bottom of the sedimentation tank 1 , and the sediment pretreatment component 3 and the drainage component 4 are both arranged in the sedimentation tank 1 .

[0030] Specifically, such as Figure 3 As shown, the sediment pretreatment assembly 3 may include a first column 31 , an overflow box 32 , a first floating plate 33 , a water inlet pipe 34 and a filter plate 35 .

[0031] Among them, the first column 31 is arranged in the sedimentation tank 1, the overflow box 32 can be slidably arranged on the first column 31 through the connecting piece 321, and the first float 33 is arranged outside the overflow box 32. The first float 33 is used to control the overflow box 32 to always float on the water surface. The filter plate 35 and the outlet end of the water inlet pipe 34 are arranged in the overflow box 32, and the outlet end of the water inlet pipe 34 is located below the filter plate 35. The filter plate 35 is used to filter the sewage when the sewage seeps through the filter plate 35, wherein the sewage that seeps through the filter plate 35 flows into the sedimentation tank 1 through the opening of the overflow box 32.

[0032] Specifically, such as Figure 1 As shown, the drainage assembly 4 may include a drainage pipe 43, a second float 42 and a second column 41, wherein the second column 41 is arranged on the first float 33, the second float 42 can be slidably arranged on the second column 41, the water inlet end of the drainage pipe 43 is arranged on the second float 42, and the drainage pipe 43 is used to discharge the surface water in the sedimentation tank 1.

[0033] It should be noted that, in order to ensure that the overflow box 32 can float, two first floating plates 33 may be provided, and the two first floating plates 33 are respectively provided at the top and the bottom of the overflow box 32 .

[0034] It is understandable that the overflow box 32 can be made of plastic, which can not only prevent sewage from corroding the overflow box 32, but also reduce the weight of the overflow box 32, requiring less buoyancy, thereby making the size of the first floating plate 33 smaller.

[0035] In an embodiment of the present application, sewage is injected into the sediment pretreatment component 3, and floating objects and large-particle sediments in the sewage are retained in the overflow box 32. The pretreated sewage flows into the sedimentation tank 1 for sedimentation, and the precipitated sewage is discharged through the drainage component 4. The drainage component 4 follows the sediment pretreatment component 3 and floats on the upper water surface of the sedimentation tank 1, which can effectively avoid the stirring of the bottom sediment and improve the separation efficiency.

[0036] In addition, when the sewage in the sedimentation tank 1 is pumped out, the drainage component 4 and the sediment pretreatment component 3 drop with the water level, and the drainage component 4 always keeps sucking the upper water surface in the sedimentation tank 1. There is no need for real-time operation by staff, which is simpler and more convenient than manual suction, and the workload is small.

[0037] When sewage needs to be treated in a sewage treatment plant, the sewage is precipitated and separated.

[0038] Specifically, if Figure 3 and Figure 5As shown, the relevant staff connects the water inlet pipe 34 to the sewage treatment plant, which can be the sewage source pool of the sewage treatment plant (the sewage source pool is a special pool for storing untreated sewage), and uses a water pump to pump the sewage from the water inlet pipe 34 to the overflow box 32. As the sewage in the overflow box 32 increases, until it overflows the filter plate 35, the floating objects and large particles of sediment in the sewage are blocked by the filter plate 35. The pretreated sewage eventually overflows the overflow box 32 and flows into the sedimentation tank 1. The sewage is filtered by the sedimentation pretreatment component 3, and the large particles in the sewage (including sediment, floating objects and flocs, etc.) are blocked in the overflow box 32, and the sewage is preliminarily filtered.

[0039] As more and more pretreated sewage flows into the sedimentation tank 1, the overflow box 32 floats under the buoyancy of the first float plate 33, and the connector 321 on the overflow box 32 floats along the first column 31, keeping the overflow box 32 always in a floating state.

[0040] Then, if Figure 4 As shown, relevant staff put precipitants or flocculants into the sedimentation tank 1 to allow the pretreated sewage to settle and precipitate. After the sewage in the sedimentation tank 1 is allowed to stand, relevant staff use an external water pump to pump water from the sedimentation tank 1 from the drain pipe 43. The pumped-out sewage can be used for deep purification in the sewage treatment plant.

[0041] As the water level in the sedimentation tank 1 decreases, the sediment pretreatment component 3 drops along with the water level, and the drainage component 4 drops along with the sediment pretreatment component 3. The second float 42 moves on the second column 41 following the water level, and the pumping end of the drainage pipe 43 is always kept sucking the upper water surface. The sediment at the bottom of the sedimentation tank 1 will not be stirred, and the separation efficiency of sewage and sediment will be higher.

[0042] It is understandable that an adsorption cover may be provided at one end of the drainage pipe 43 close to the second floating plate 42 , and a filter may be provided in the adsorption cover to further filter residual floating objects in the sewage in the sedimentation tank 1 .

[0043] To better illustrate the above embodiment, in one embodiment of the present application, Figure 5 As shown, a first discharge port 36 is provided at the bottom of the overflow box 32 to discharge the sediment 7 in the overflow box 32 . The bottom of the sedimentation tank 1 is funnel-shaped, and a second discharge port 11 is provided at the center of the bottom of the sedimentation tank 1 .

[0044] Wherein, both the first discharge port 36 and the second discharge port 11 are provided with electromagnetic valve switches, and both electromagnetic valve switches are controlled by a controller.

[0045] In the daily maintenance and cleaning of the sewage treatment plant, in addition to the maintenance of related machinery, the overflow box 32 and the sedimentation tank 1 also need to be cleaned.

[0046] Specifically, the relevant staff can open the electromagnetic valve switch at the first discharge port 36 through the controller, and the sewage retained in the overflow box 32 will be discharged from the first discharge port 36 into the sedimentation tank 1 with the sediment. Then the relevant staff will open the electromagnetic valve switch at the second discharge port 11 through the controller to discharge the sediment in the sedimentation tank 1 together with a small amount of sewage.

[0047] It should be noted that for the cleaning of the overflow box 32 and the sedimentation tank 1, relevant staff are required to control the electromagnetic valve switches at the first discharge port 36 and the second discharge port 11 to open, and use cleaning liquid to flush the overflow box 32 and the sedimentation tank 1, and the final cleaning liquid is discharged from the second discharge port 11.

[0048] For easy operation, the controller may be externally connected to a key switch, and relevant staff can control the opening and closing of the electromagnetic valves at the first discharge port 36 and the second discharge port 11 by pressing the key switch.

[0049] In one embodiment of the present application, Figure 5 As shown, a limiting device 37 is provided at the bottom of the overflow box 32, and the limiting device 37 includes a support rod and a support plate.

[0050] The support rod is vertically arranged at the bottom of the overflow box 32 , the support plate is hinged on the support rod, an overflow port 38 is opened on the overflow box 32 , and the overflow port 38 is arranged above the filter plate 35 .

[0051] It can be understood that as the sewage in the sedimentation tank 1 gradually decreases, the overflow box 32 follows the water level drop until the bottom of the overflow box 32 contacts the funnel-shaped bottom of the sedimentation tank 1. The limiting device 37 supports the overflow box 32 to prevent the overflow box 32 from causing damage between the connecting piece 321 and the first column 31 due to the tilting tendency.

[0052] When the sewage treatment plant discharges the sewage in the sedimentation tank 1 , the overflow box 32 descends along with the sewage in the sedimentation tank 1 .

[0053] Specifically, when the overflow box 32 follows the sewage in the sedimentation tank 1 and descends to the bottom, the support plate touches the bottom of the sedimentation tank 1 and rotates to an angle that fits the bottom of the sedimentation tank 1. The support rod and the side of the overflow box 32 away from the limit device 37 jointly support the overflow box 32, so that the overflow box 32 is in a stable and steady state.

[0054] In one embodiment of the present application, Figure 4As shown, a mounting plate 2 is provided on the sedimentation tank 1, and the water inlet end of the water inlet pipe 34 and the water outlet end of the drain pipe 43 are both provided on the mounting plate 2, so that the water inlet end of the water inlet pipe 34 and the water outlet end of the drain pipe 43 are fixed, which facilitates the external connection of a water pump to the water inlet end of the water inlet pipe 34 and the water outlet end of the drain pipe 43, making it more convenient for relevant staff to discharge sewage into the overflow box 32 and pump it out from the sedimentation tank 1.

[0055] Among them, the water inlet pipe 34 and the drainage pipe 43 are both elastic telescopic tubes to ensure that the use of the water inlet pipe 34 and the drainage pipe 43 is still effective when the sediment pretreatment component 3 and the drainage component 4 move up and down. At the same time, in order to ensure the stability of the water inlet pipe 34, the outlet end of the water inlet pipe 34 is fixed tightly to the overflow box 32 by a buckle.

[0056] In summary, the sewage sediment separation and discharge device of the embodiment of the present application can reduce the agitation of bottom sediment when sewage is discharged, improve separation efficiency, and is simple to operate and requires less workload.
