Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment devices, and in particular relates to a high-efficiency sediment cleaning device in fillers of a clarifier. Background Art

[0002] The high-efficiency clarification tank is a common process section in sewage treatment, which consists of two parts: a reaction zone and a sedimentation zone. The mixed liquid entering the sedimentation zone from the reaction zone undergoes mud-water separation in the sedimentation zone. As the sewage rises through the filler, the pollutants in the water will settle in the filler and adhere to the inner wall of the filler. As time goes by, a large amount of sludge will accumulate inside the filler, clogging the filler, thereby reducing the sedimentation effect and affecting the effluent quality.

[0003] The above problems can only be solved by temporarily stopping the equipment, lowering the water level, and manually cleaning the filler. However, this method has technical problems such as affecting the stability of system operation, high labor intensity of flushing, and long time required. Utility Model Content

[0022] Embodiment

[0023] This embodiment provides a device for cleaning sediments in the filler of an efficient clarifier, including a gas supply device, a main pipeline 1, branch pipelines 3, and coiled pipes 4;

[0024] One end of the main pipeline 1 is connected to the gas supply device, and the other end is connected to two or more branch pipelines 3; each branch pipeline 3 extends downward along the pool wall to the lower part of the filler 7, and is respectively connected to a group of coiled pipes 4 evenly arranged below the filler 7; the coiled pipes 4 are horizontally filled below the filler 7 with equal spacing, and multiple air holes 9 are arranged at equal intervals along the length direction on the lower side of each coiled pipe 4, and the adjacent two air holes 9 are arranged alternately at about 120°.

[0025] It should be noted that the main pipeline 1 can be introduced from the center position along the pool length direction of the top 8 of the efficient clarifier. After entering the pool body 6, it is divided into two or more branch pipelines 3 made of PVC along the pool wall. In the figure, there are two branch pipelines 3, which extend to the lower part of the filler 7 and are connected to the coiled pipes 4 evenly arranged below the filler 7. Each branch pipeline 3 corresponds to a group of coiled pipes. The coiled pipes 4 are horizontally filled below the filler 7 with equal spacing.

[0026] It should be noted that the gas supply device adopts publicly known technology equipment, such as an air compressor, etc.

[0027] The branch pipeline 3 is attached to the pool wall and can be fixed by fixing parts in publicly known technology, which will not be elaborated here. The diameter and quantity of the branch pipeline 3 are determined according to the actual situation and can be evenly arranged along the pool length direction.

[0028] In a preferred embodiment, one branch pipeline valve 2 for controlling the opening and closing of the branch pipeline is provided on each branch pipeline 3. It should be noted that the branch pipeline valve controls the opening or closing of each branch pipe. The branch pipeline valve 2 is installed on each branch pipeline, near the pool top 8, which is convenient for switching operations. The branch pipeline valve is usually a manual valve and can also be remotely controlled by a host computer. An electric valve can be selected, and the control principle and method both adopt publicly known technology.

[0029] In a preferred embodiment, the main pipeline 1, branch pipelines 3, and coiled pipes 4 are all made of PVC. It should be noted that the pipeline and pipe fitting materials in the present application scheme are all PVC, with strong corrosion resistance. The PVC pipelines and pipe fittings can be fixed by bonding, with a simple structure, convenient for installation and disassembly, and low cost.

[0030] Among them, each coiled pipe 4 adopts a square ring pipeline.

[0031] Among them, the lower end of the coil pipe 4 is supported by a plurality of coil pipe support beams 5 arranged at uniform intervals, and both ends of the support beam 5 are fixed on the pool wall.

[0032] Working principle: This device is in a normally closed state. When the packing needs to be cleaned, the air supply device is turned on, and the branch pipeline valve 2 is opened. Compressed air will enter each component branch pipeline 3 through the main pipeline 1 and quickly fill the coil pipe 4, and then be ejected through the air holes 9 at the bottom of the coil pipe 4. Because the adjacent two air holes are arranged alternately at about 120°, a uniform series of compressed air bubbles will be formed under the packing 7. The bubbles will expand and burst during the rising process, thereby disturbing the sediment in the packing 7, causing part of the sediment to slide along the packing wall into the bottom of the sedimentation tank, and a small part to float to the water surface with the supernatant and then be discharged through the surface skimming device. Each cleaning lasts about 15 - 30 minutes, and then the air source is cut off by closing the branch pipeline valve 2. The whole process realizes the effective cleaning of the packing 7, and as much as possible realizes continuous production, reduces the maintenance time, and reduces the labor intensity of workers.

[0033] It should be noted that for the structures not detailed in this application, well-known technologies are adopted.

[0034] The above shows and describes the basic principle, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present utility model and are not used to limit the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
