[0020] This embodiment discloses a sewage treatment device with a constant water level, including a reaction box 10, a drainage mechanism 20, and a floating mud removal mechanism 30. Figure 1 and Figure 2 As shown, the details are as follows:

[0021] A sewage inlet is provided on the side wall of the reaction box 10 , and the sewage inlet is connected to a water inlet pump, and the sewage is pumped into the reaction box 10 through the water inlet pump.

[0022] like Figure 3 As shown, the drainage mechanism 20 is arranged in the reaction box 10, and the drainage mechanism 20 is located below the liquid surface of the sewage; the drainage mechanism 20 includes a water collecting pipe 21 and a water outlet pipe 22; the water collecting pipe 21 is located below the liquid surface of the sewage, and the water collecting pipe 21 is horizontally arranged, the axial ends of the water collecting pipe 21 are closed, and a plurality of water collecting holes 21a are distributed on the outer periphery of the water collecting pipe 21, and the clean water in the middle of the reaction box 10 enters the interior of the water collecting pipe 21 through the water collecting holes 21a, wherein the horizontally arranged water collecting holes 21a can make the water in the reaction box 10 flow evenly into the interior of the water collecting pipe 21 without generating vortex.

[0023] like Figure 3As shown, one end of the water outlet pipe 22 is connected to the middle position of the water collecting pipe 21, and the other end of the water outlet pipe 22 is used to discharge clean water. In this embodiment, a clean water tank 40 is provided on one side of the reaction box 10, and the other end of the water outlet pipe 22 is connected to the clean water tank 40, so that the water outlet pipe 22 can discharge the clean water in the reaction box 10 into the clean water tank 40, wherein an overflow weir 41 is provided at the upper position of the clean water tank 40, and the clean water overflowing to the overflow weir 41 can be discharged outward.

[0024] like Figure 3 As shown, in some preferred embodiments, the drainage mechanism 20 also includes a hanging assembly 23, which includes a fixing frame 231 and a hanger 232 (there are two hangers), the fixing frame 231 is fixedly mounted on the inner peripheral wall of the reaction box 10, and the fixing frame 231 is provided with a plurality of first connection holes at intervals along the height direction; one end of the hanger 232 is fixed to the water collecting pipe 21 by a clamp or a U-bolt, etc., wherein the hanger 232 is provided with a plurality of second connection holes for cooperating with the first connection holes along the height direction, and bolts, rivets and other connecting parts can be used to pass through the first connection holes and the second connection holes to achieve the fixation between the hanger 232 and the fixing frame 231. When the position of the water collecting pipe 21 needs to be adjusted, it is only necessary to select the connection position of the first connection hole and the second connection hole according to actual needs.

[0025] like Figure 4 As shown, the de-sludge mechanism 30 is disposed in the reaction box 10, and the de-sludge mechanism 30 is located directly above the drainage mechanism 20. The de-sludge mechanism 30 includes a first bracket 31, a screw 32, a first nut 33, a second bracket 34, a submersible sewage pump 35, a de-sludge collecting head 36, a de-sludge pipe 37 and a second nut 38.

[0026] like Figure 4 As shown, the first bracket 31 is fixed on the inner wall of the reaction box 10, and the first bracket 31 is located directly above the water collecting pipe 21; the first bracket 31 is provided with a first sliding hole, and the screw 32 is provided with the first sliding hole along the height direction, and the screw 32 can slide up and down in the first sliding hole; two first nuts 33 are both threadedly connected to the screw 32, and the two first nuts 33 are respectively located on the upper and lower sides of the first sliding hole, and the first nuts 33 and the first bracket 31 are in contact, so as to achieve the stability of the position between the screw 32 and the first bracket 31. When the position of the second bracket 34 needs to be adjusted, it is only necessary to screw the first nut 33 and pull the screw 32 up and down. In order to ensure stability, there are two screws 32 in this embodiment.

[0027] like Figure 4As shown, the second bracket 34 is connected to the screw rod 32, and the second bracket 34 is used to install the submersible sewage pump 35, wherein the de-floating mud mechanism 30 also includes two second nuts 38 threadedly connected to the screw rod 32, and a stable connection between the second bracket 34 and the screw rod 32 is achieved through the second nuts 38, specifically as follows: a second sliding hole is provided on the second bracket 34, and the lower end of the screw rod 32 is penetrated by the second sliding hole along the height direction, and the two second nuts 38 are respectively located on the upper and lower sides of the second sliding hole, and the second nuts 38 can be abutted against the second bracket 34, so that the second bracket 34 can be stably hung on the screw rod 32.

[0028] like Figure 4 As shown, the submersible sewage pump 35 is arranged on the upper surface of the second bracket 34, and the submersible sewage pump 35 is used to discharge the sludge in the reaction box 10 to the outside.

[0029] like Figure 4 As shown, the floating mud collecting head 36 is vertically arranged and is located directly above the water collecting pipe 21, and the upper plane of the floating mud collecting head is lower than the liquid surface of the sewage, and the collecting port of the floating mud collecting head 36 is lower than the liquid surface of the reaction tank, for example, the floating mud collecting head 36 is 1 cm to 5 cm below the liquid surface, and the lower end of the floating mud collecting head 36 is connected to the input end of the submersible sewage pump 35, and the floating mud collecting head 36 is used to collect the floating mud on the liquid surface. Among them, the submersible sewage pump 35 of this embodiment can be linked with the water inlet pump, and when the water inlet pump is turned on or turned on for a certain period of time, the submersible sewage pump 35 will run again to achieve the purpose of concentrated discharge of floating mud.

[0030] like Figure 2 As shown, one end of the sludge discharge pipe 37 is connected to the output end of the submersible sewage pump 35, and the other end of the sludge discharge pipe 37 is used to discharge sludge. In this embodiment, a sludge tank 50 is provided on one side of the reaction box 10, and the other end of the sludge discharge pipe 37 is connected to the sludge tank 50. The sludge tank 50 can temporarily store the discharged sludge for later centralized treatment.

[0031] In some preferred embodiments, a liquid level detection unit (not shown) is provided in the reaction box 10, and the liquid level height of the sewage is monitored in real time by the liquid level detection unit. In the reaction box 10, if the drainage mechanism 20 fails (for example, the water collection hole 21a of the water collection pipe 21 is blocked), the liquid level height in the reaction box 10 may exceed a predetermined value. In this embodiment, the liquid level detection unit is designed to monitor the liquid level height of the sewage in real time, which can reflect the working state of the drainage mechanism 20, such as the drainage efficiency of the drainage mechanism 20.

[0032] The working principle of the sewage treatment device in this embodiment is as follows:

[0033] When water enters the reaction box 10, the water flow will be squeezed into the water collecting pipe 21, that is, the sewage flows into the water collecting pipe 21 through the water collecting hole 21a, and then flows to the clean water tank 40 through the outlet pipe 22, while the floating mud floating on the water surface will not be brought into the water collecting pipe 21 with the water flow, nor will it flow into the clean water tank 40.

[0034] During the water flow, the floating mud on the water surface will drift with the water flow to the top of the water collecting pipe 21 and gather. At this time, the submersible sewage pump 35 is turned on, and the floating mud on the water surface will be sucked into the floating mud collecting head 36. The sucked floating mud flows into the sludge pool 50 through the submersible sewage pump 35 and the mud discharge pipe 37. After the submersible sewage pump 35 works for a certain period of time, the floating mud on the water surface is cleaned up.

[0035] The sewage treatment device of this embodiment has the following advantages:

[0036] 1. This embodiment achieves drainage at a constant liquid level and prevents floating mud from being discharged with the water flow, thereby improving the effluent water quality;

[0037] Second, this embodiment realizes the function of collecting and cleaning the floating mud in the reaction tank, reduces the workload of the operation and maintenance personnel, and reduces the operation and maintenance costs;

[0038] 3. This embodiment realizes the height adjustment function of the de-sludge mechanism 30, which can adapt to the change of the liquid level height caused by the unevenness of the equipment foundation.

[0039] The above is only a specific implementation of the present application. Those skilled in the art can clearly understand that for the convenience and simplicity of description, the specific working processes of the systems, modules and units described above can refer to the corresponding processes in the aforementioned method embodiments, and will not be repeated here. It should be understood that the protection scope of the present application is not limited to this. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed in this application, and these modifications or replacements should be included in the protection scope of this application.
