Description

Technical Field

[0001] This utility model belongs to the field of sedimentation tank technology, specifically relating to a sedimentation tank sludge hopper sludge detection device. Background Technology

[0002] Sedimentation tanks are the core unit of water treatment processes (municipal sewage, tap water purification, industrial wastewater treatment), and their bottom sludge hoppers are responsible for collecting settled sludge. If too much sludge accumulates in the sludge hoppers, the sedimentation efficiency will decrease, the sludge pump will be overloaded, and pipe blockages will increase energy consumption and maintenance costs. In addition, compacted sludge can easily form biogas, which may cause explosions or poisoning during manual cleaning.

[0003] Currently, when inspecting the sludge hopper in sedimentation tanks, one can manually insert a measuring rod into the hopper to measure the depth, or sample and test the sludge concentration to indirectly determine the sludge accumulation. Although this method is low-cost, it is inefficient and carries the risks of slipping, falling, and biogas poisoning. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a sludge accumulation detection device for sedimentation tank sludge hoppers. This solves the problem that when detecting sludge accumulation in sedimentation tank sludge hoppers, it is possible to manually insert a measuring rod into the sludge hopper to measure the depth or indirectly determine the sludge accumulation by sampling and testing the sludge concentration. Although this method is low in cost, it is inefficient and poses risks of slipping and falling and biogas poisoning.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a sedimentation tank sludge hopper sludge detection device, comprising a sedimentation tank, a sludge hopper fixedly connected to one side of the sedimentation tank, a sludge suction pipe connected to the lower end of the sludge hopper, and a detection device provided on one side of the lower end of the sludge hopper. The detection device includes a sludge suction pipe, an electrically controlled valve one, a sludge suction pump, a connecting pipe, an electrically controlled valve two, a motor, and an auger. The sludge suction pump is fixedly installed on the side of the sedimentation tank. The electrically controlled valve one is equidistantly connected to the side of the sludge suction pipe near the sludge hopper. The input end of the electrically controlled valve one is connected to the inner side of the sludge hopper. A connecting pipe is provided between the sludge suction pipe and the sludge suction pump.

[0006] The beneficial effects of this utility model are as follows: By alternately opening the first electric control valve from top to bottom until obvious sludge and flocculent matter are drawn out, the sludge accumulation content in the sludge hopper can be determined. By continuing to open the first electric control valve downwards for further suction, the specific stratification of sludge in the sludge hopper can be further determined by the sludge and sewage drawn out. No manual probe detection or manual sampling is required, which effectively avoids the danger of manual sampling and increases the convenience of sludge detection.

[0007] To scrape the inner wall of the mud bucket;

[0008] As a further improvement to the above technical solution: a stirring rod is provided on the inner side of the mud hopper, and the stirring rod is set close to the inner wall of the mud hopper.

[0009] The beneficial effects of this improvement are as follows: the stirring rod can be driven by a drive motor located at the top of the sedimentation tank, which can stir the sludge, promote the discharge of sludge, and scrape the inner wall of the sludge hopper to prevent the sludge from forming a stubborn layer and to prevent the sludge from entering the electric control valve.

[0010] To facilitate visual observation of whether the accumulated mud has been properly removed;

[0011] As a further improvement to the above technical solution: the mud suction pipe is made of transparent high-strength glass.

[0012] The beneficial effect of this improvement is that it makes it easier to visually observe whether the accumulated mud has been properly removed.

[0013] To flush the mud suction pipe regularly;

[0014] As a further improvement to the above technical solution: an electrically controlled valve 2 is connected to the lower side of the mud-squeezing pipe.

[0015] The beneficial effects of this improvement are: opening the second electrically controlled valve connects the water pipe below, allowing for periodic flushing of the sludge pumping pipe.

[0016] To prevent some silt from settling at the bottom of the sludge suction pipe;

[0017] As a further improvement to the above technical solution: a motor is fixedly installed at the lower end of the mud-draining pipe, and the output end of the motor passes through the inside of the mud-draining pipe and is fixedly connected to an auger.

[0018] The beneficial effect of this improvement is that the auger can stably push the mud and sand upwards, preventing some of the mud and sand from settling at the bottom of the sludge suction pipe.

[0019] In summary, the beneficial effects of this technical solution are as follows: by alternately opening the first electrically controlled valve from top to bottom until obvious sludge and flocculent matter are drawn out, the sludge accumulation content in the sludge hopper can be determined. Continuing to open the first electrically controlled valve downwards for further suction allows for a more accurate assessment of the specific stratification of the sludge in the sludge hopper based on the extracted sludge and wastewater. This eliminates the need for manual probe testing and manual sampling, effectively avoiding the risks associated with manual sampling and increasing the convenience of sludge accumulation detection.

[0026] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0027] like Figure 1 — Figure 4 As shown: A sludge detection device for a sedimentation tank sludge hopper includes a sedimentation tank 1. A sludge hopper 2 is fixedly connected to one side of the sedimentation tank 1. A sludge suction pipe is connected to the lower end of the sludge hopper 2. A detection device 3 is installed on one side of the lower end of the sludge hopper 2. The detection device 3 includes a sludge suction pipe 31, an electrically controlled valve 32, a sludge suction pump 33, a connecting pipe 34, an electrically controlled valve 35, a motor 36, and an auger 37. The sludge suction pump 33 is fixedly installed on the side of the sedimentation tank 1. The sludge suction pipe 31 is close to the sludge hopper. An electrically controlled valve 32 is equidistantly connected to one side of the hopper 2. The input end of each of the electrically controlled valves 32 is connected to the inside of the hopper 2. A connecting pipe 34 connects the sludge suction pipe 31 and the sludge suction pump 33. The electrically controlled valves 32 are opened alternately from top to bottom until obvious sludge and flocculent matter are pumped out. This indicates the sludge content in the hopper 2 at that time. The electrically controlled valves 32 are opened further downwards to continue pumping. The amount of sludge in the hopper 2 can be further determined by observing the pumped-out sludge and wastewater. The specific stratification situation does not require manual probe detection or manual sampling, effectively avoiding the dangers of manual sampling and increasing the convenience of sludge detection. The inner side of the sludge hopper 2 is equipped with a stirring rod, which is set close to the inner wall of the sludge hopper 2. The stirring rod can be driven by a drive motor set at the top of the sedimentation tank 1. It can stir the sludge, promote the discharge of sludge, and also scrape the inner wall of the sludge hopper 2 to prevent the sludge from forming a stubborn layer and to prevent the sludge from obstructing the entry of the sludge into the first electric control valve 32. The sludge suction pipe 31 is made of transparent high-strength glass, which makes it easy to see whether the sludge has been normally extracted. The lower side of the sludge suction pipe 31 is connected to the second electric control valve 35. When the second electric control valve 35 is opened, a water pipe is connected below, which can periodically flush the sludge suction pipe 31. The lower end of the sludge suction pipe 31 is fixedly equipped with a motor 36. The output end of the motor 36 passes through the inner side of the sludge suction pipe 31 and is fixedly connected to an auger 37. The auger 37 can stably push the sludge upward and prevent some sludge from settling at the bottom of the sludge suction pipe 31.

[0028] Working principle and usage process of this utility model:

[0029] In this technical solution, sedimentation tank 1 is a common inclined tube sedimentation tank, which can be directly referred to as an existing inclined tube sedimentation tank. The specific structure will not be described in detail. After the sludge settles into sludge hopper 2, the sludge pump is turned on, and the sludge accumulated in sludge hopper 2 can be pumped away through the sludge suction pipe. However, due to factors such as sludge pipe blockage, sludge pump failure, and increased water pollution, the sludge accumulation in sludge hopper 2 will increase. By detecting the amount of sludge accumulated in sludge hopper 2, the pumping status of the sludge pipe and sludge pump can be judged. During sludge sedimentation, the more sludge and silt there is generally at the bottom, and the silt generally accumulates in the lower layer. The upper layer generally contains finer sludge, flocculent suspended matter, and a small amount of sludge from the sediment. During detection, the uppermost solenoid valve 32 can be opened first to start the pumping process. The mud pump 33 draws sludge from the mud suction pipe 31 through the connecting pipe 34. The mud suction pipe 31 draws sludge and sewage into the mud through the uppermost solenoid valve 32. The sludge and sewage are then collected at the output of the mud pump 33 to determine the content of the sewage and sludge. The uppermost solenoid valve 32 is then closed, and the second valve is opened to repeat the process of drawing sludge and sewage to determine their content. This process continues until obvious silt and flocculent matter are drawn, which indicates the sludge content in the mud hopper 2. The solenoid valve 32 is then opened to continue drawing sludge. The sludge and sewage drawn out can be used to further determine the specific stratification of the sludge in the mud hopper 2. No manual probe testing or manual sampling is required, effectively avoiding the dangers of manual sampling and increasing the convenience of sludge detection.
