DETAILED DESCRIPTION

[0031] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. The principles and features of the present invention are described below in combination with the accompanying drawings. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict. The examples cited are only used to explain the present invention and are not used to limit the scope of the present invention.

[0032] Example 1

[0033] This embodiment provides a sedimentation cavity filler, referring to Figure 1 and Figure 2 .

[0034] The sedimentation cavity filler comprises:

[0035] The upper plate group has an angle of 0 to 90 degrees with the vertical direction, and each upper plate 41 in the upper plate group is along the first direction ( Figure 1 The upper plates 41 are arranged in parallel (in the direction of the arrow in the middle) and the lower ends of the upper plates 41 are flush; a rising channel for the mud-water mixture is formed between two adjacent upper plates 41; in this embodiment, the lower ends of the upper plates 41 are in the same horizontal plane;

[0036] The angle between the lower plate group and the upper plate group is not equal to 180 degrees, and the lower plate group includes a first lower plate 42 and a second lower plate 43 arranged at intervals, the first lower plate 42 and the second lower plate 43 are arranged in parallel along the first direction, and the upper end of the first lower plate 42 is connected to the lower end of the upper plate 41 in a one-to-one correspondence; the second lower plate 43 and the first lower plates 42 on both sides thereof respectively form a first channel 401 and a second channel 402, wherein the side close to the upper plate 41 ( Figure 1 The left side is the first channel 401, and the other side is the second channel 402. Sealing plates 423 are provided at both ends of the first channel 401; Figure 1 The lower ends of every two adjacent upper plates 41 correspond to the first channel 401 and the second channel 402, the first channel 401 is on the left, and the second channel 402 is on the right.

[0037] Under the action of airflow, the mud-water mixture enters the second channel 402 from the side, and continues upward to enter the mud-water mixture rising channel formed by the upper plate group, and then under the action of the density flow, the clean water with lower density in the mud-water mixture flows upward, and the muddy water with higher density flows downward into the first channel 401. During the rising and settling process of the mud-water mixture, the sludge settling process can be effectively prevented from being affected by the upward flow disturbance of the mud-water mixture, thereby improving the sedimentation efficiency and surface load of the circulation clarifier, thereby improving the processing flux of the settling chamber and achieving a better mud-water separation effect.

[0038] In this embodiment, the first lower plate 42 and the second lower plate 43 are arranged vertically, which can better prevent the sludge settling process from being affected by the upward flow disturbance of the mud-water mixture.

[0039] In this embodiment, the upper ends of the first lower plate 42 and the second lower plate 43 are flush, that is, the upper ends of the first lower plate 42 and the second lower plate 43 are in the same horizontal plane and connected to the lower end of the upper plate 41 .

[0040] In other embodiments, the upper end of the second lower plate 43 may be higher than the upper end of the first lower plate 42 but does not conflict with the upper plate 41, so as to cope with mud-water mixtures with different sludge contents and different influent fluxes.

[0041] In this embodiment, in order to ensure the supporting strength, a plurality of longitudinal connecting plates 425 are arranged between the first lower plate 42 and the second lower plate 43 .

[0042] In order to ensure the support strength, a longitudinal first support plate 412 is arranged between the upper plates 41. Furthermore, a support rod 413 is arranged between the first support plates 412.

[0043] In this embodiment, a ramp plate 426 is provided on one side of the second lower plate 43 located at the second channel 402, and the ramp plate 426 extends obliquely upward from the end portion to the middle portion of the second lower plate 43;

[0044] Two ramp plates 426 are arranged on one side of the second lower plate 43, and the two ramp plates 426 are mirror-symmetrical with respect to the vertical center line of the second lower plate 43. The ramp plates 426 can be used as a mud-water mixture flow passage, and are used to ensure that the mud-water mixture can evenly enter the mud-water mixture rising passage, thereby promoting the sedimentation and separation effect of the sludge.

[0045] This embodiment provides a preferred implementation method: the lower edges of the sealing plates 423 arranged at both ends of the first channel 401 are higher than the lower edges of the first lower plate 42 and the second lower plate 43, and the mud-water mixture can enter the sedimentation chamber where the sedimentation chamber filler is installed or the bottom plate of the circulating clarifier from the lower edge of the sealing plate 423 to prevent mud from accumulating on the bottom plate.

[0046] Example 2

[0047] This embodiment provides a sedimentation chamber, in which the sedimentation chamber filler of embodiment 1 is arranged. Figure 3 and Figure 4 .

[0048] Figure 3 and Figure 4 Schematic diagram of the internal structure of the circulating clarifier 12 including the settling chamber 6 in this embodiment 2, Figure 4 The direction of the arrow in is the first direction.

[0049] As a preferred embodiment, the water inlet 61 of the settling chamber 6 in this embodiment is arranged at the end of the lower plate group. Under the action of the airflow generated by the gas device, the mud-water mixture enters the annular flow clarifier 12 from the guide hole 212 above the guide channel 22 of the annular flow clarifier 12, and then flows downward from the water inlet 61 of the settling chamber 6 into the settling chamber 6. Since the sealing plates 423 are arranged on both sides of the first channel 401, the mud-water mixture can only enter from the second channel 402.

[0050] In this embodiment, the position of the water inlet 61 of the sedimentation chamber on the cavity wall 62 of the sedimentation chamber parallel to the first direction is within the height range of the lower plate group, so that the mud-water mixture entering from the diversion channel 22 can directly enter from the side of the second channel 402, which will neither disturb the water flow in the upper plate group nor the water flow under the lower plate group.

[0051] In this embodiment, the sedimentation chamber 6 further comprises:

[0052] An overflow trough 30 is located above the upper plate group;

[0053] An air flushing pipe 52 is located below the lower plate group;

[0054] A gate 31 is installed at the water outlet of the overflow tank 30 , and the gate 31 is closed before gas is input into the gas flushing pipe 52 .

[0055] The gate 31 is used to block the water outlet of the overflow tank 30 and control whether the circulating clarifier discharges water. Before the gas is input into the gas flushing pipe 52, the gate 31 is closed. The gate 31 can be set to be electrically controlled to open and close.

[0056] In this embodiment, the air flushing pipe 52 and the electrically controlled gate 31 are linked to each other through the backwashing program. Specifically, when the backwashing program is started, the electrically controlled gate 31 is closed first to cover the water outlet, and then the air flushing pipe 52 starts to take in air to backwash the lower plate group and the upper plate group. After the backwashing is completed, the backwashing program is closed, the mud-water mixture is automatically settled and separated, and the supernatant overflows to the overflow tank 30, and the electrically controlled gate 31 is opened, and the supernatant flows out through the water outlet.

[0057] In this embodiment, the sedimentation chamber 6 further comprises:

[0058] A support frame (not shown in the drawings) is fixedly connected to the wall of the sedimentation chamber, and comprises a bottom support frame (not shown in the drawings) and a side support frame (not shown in the drawings):

[0059] The bottom support frame is supported below the lower plate group;

[0060] The side support frame supports the side where the upper plate group is tilted.

[0061] The support frame is used to support the sedimentation chamber filler.

[0062] Compared with the prior art, the technical effects that can be achieved by the sedimentation chamber provided in this embodiment include:

[0063] (1) The structure of the upper plate group and the lower plate group in the sedimentation chamber filler forms three channels, namely, a mixed liquid flow channel (second channel 402), a mixed liquid rising channel (channel between the upper plates 41), and a sludge return channel (first channel 401). The mud-water mixed liquid enters the mixed liquid rising channel through the flow channel. Under the action of the heterogeneous flow, the supernatant with low density flows upward from the mixed liquid rising channel, and the sludge with high density flows downward through the specific sludge return channel. The arrangement of these three channels can effectively prevent the sludge sedimentation process from being affected by the flow disturbance of the mud-water mixed liquid, thereby improving the sedimentation efficiency and surface load of the sedimentation chamber using the sedimentation chamber filler, and achieving a better mud-water separation effect and a higher water outlet flux.

[0064] (2) A ramp plate 426 is arranged on the second lower plate 43 of the sedimentation chamber filler on one side of the second channel 402. The ramp plate 426 can be used as a flow channel for the mud-water mixture, which can ensure that the mud-water mixture can evenly enter the mixed liquid rising channel and promote the sedimentation and separation effect of the sludge.

[0065] (4) The settling chamber provided in this embodiment is provided with a gate 31 linked to the backwashing procedure. When the backwashing procedure is started, the gate 31 which is electrically controlled to open and close is closed first, and then the air flushing pipe starts to flush the sludge on the upper plate group and the lower plate group. After the air flushing is completed, the gate 31 which is electrically controlled to open and close is opened, and the clarified water is discharged from the water outlet. Compared with the previous circulation clarifier, it can effectively prevent the backwashing process from affecting the water quality of the effluent, and ensure that the effluent meets the standards for subsequent treatment.
