Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a shallow water lake sewage gallery purification treatment device. Background Art

[0002] A lake sewage corridor refers to a pipeline system that transports sewage generated in cities or industrial areas to lakes for treatment or discharge. This sewage corridor system usually includes sewage pipes, pumping stations, regulating tanks and other facilities, which are used to collect, transport and treat sewage to reduce the load on urban sewage treatment plants while protecting the water quality of lakes. The design and operation of lake sewage corridors can effectively control sewage discharge and reduce the impact on the ecological environment of lakes.

[0003] For example, the patent publication number CN114149141A is a shallow lake sewage corridor purification treatment system. By setting up a buffer filter device, the impact of water is eliminated to avoid long-term flushing of industrial sewage, which may cause damage to the decontamination device and splashing of sewage. Larger suspended solids in domestic sewage or industrial sewage are filtered, and the filter box stores polluted garbage to facilitate garbage cleaning by staff. The magnetic suction device removes fine ferromagnetic particles in the sewage, and the decontamination device precipitates the sewage that has been initially filtered, and the precipitated sludge is reused to provide nutrients for emergent plants. The adsorption device in the decontamination device precipitates together with related elements in the water body through adsorption or flocculation, thereby eliminating pollutants such as phosphorus and nitrates in the sewage.

[0004] The above equipment uses a filtering device to filter impurities in sewage. Since there are generally more impurities in sewage, a large amount of impurities will accumulate on the filtering device after a short period of filtration. These impurities will clog the filtering device. Manual cleaning alone may not be able to clean the filtering device in time, reducing the filtering speed and filtering effect of sewage.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] A lake sewage corridor refers to a pipeline system that transports sewage generated in cities or industrial areas to lakes for treatment or discharge. Before the sewage is discharged into the lake through the corridor, it needs to be filtered and purified to reduce pollution to the lake. The utility model provides a purification treatment device that can clean the filter device while filtering the sewage, so that the filter device can maintain a good filtering effect for a long time.

[0025] like Figure 1-Figure 6 As shown, the utility model provides a technical solution: a shallow water lake sewage corridor purification treatment device, comprising a treatment mechanism 1, a cleaning mechanism 2 is arranged on the top of the treatment mechanism 1, the treatment mechanism 1 comprises a treatment pool 101, water inlet plates 102 and drainage plates 108 are arranged at both ends of the treatment pool 101, a square frame 103 is arranged on the inner wall of the treatment pool 101, a filter screen 104 for filtering impurities is arranged in the square frame 103, a sewage pipe 109 for discharging impurities is arranged on one side of the treatment pool 101, and an electric valve 110 is fixedly installed on one side of the sewage pipe 109;

[0026] The cleaning mechanism 2 includes two fixed plates 201, both of which are fixedly installed on the top of the treatment tank 101, and a reciprocating screw 202 for reciprocating cleaning is rotatably installed between the two fixed plates 201. The outer wall of the reciprocating screw 202 is connected with a cleaning rod 203 through a threaded sliding sleeve. A motor 204 for driving the reciprocating screw 202 is fixedly installed on one side of one of the fixed plates 201, and one end of the cleaning rod 203 is provided with bristles 205 for cleaning the filter 104.

[0027] It should be noted that when in use, the sewage pipe is connected to the water inlet plate 102, and the filter 104 can filter the impurities in the sewage. The motor 204 is started to drive the reciprocating screw 202 to rotate, and the cleaning rod 203 can be driven to slide back and forth in the treatment tank 101 through the thread, thereby driving the bristles 205 to rub on the surface of the filter 104, and the impurities attached to the filter 104 are scraped off to prevent the accumulation of impurities and cause the filter 104 to be blocked, so that the filter 104 can maintain a good filtering effect for a long time.

[0028] Among them, a partition 105 is fixedly installed on the inner wall of the treatment tank 101, a water channel 113 is opened on one side of the partition 105, a disinfectant box 106 is fixedly installed on one side of the treatment tank 101 near the drain plate 108, and a nozzle 107 connected to the disinfectant box 106 is arranged on the inner wall of the treatment tank 101. A micro water pump is arranged in the disinfectant box 106, and the micro water pump is connected to the nozzle 107.

[0029] It should be noted that, by setting up the partition 105, a compartment can be separated in the treatment tank 101 for temporarily storing the filtered sewage. By starting the micro water pump and spraying disinfectant into the treatment tank 101 through the nozzle 107, the filtered sewage can be chemically disinfected.

[0030] Among them, plug plates 111 are provided at both ends of the square frame 103, and a pull plate 112 is fixedly installed between the tops of the two plug plates 111. The inner wall of the processing pool 101 is opened with two slots 115, and the two plug plates 111 are slidably inserted in the two slots 115 respectively.

[0031] It should be noted that, after the filter 104 is damaged after long-term use, the pull plate 112 is pulled to drive the two plug plates 111 to disengage from the two slots 115, so that the square frame 103 can be taken out and the filter 104 can be replaced.

[0032] A fixing rod 116 for supporting the cleaning rod 203 is fixedly installed on the inner wall of the treatment tank 101 .

[0033] It should be noted that the fixed rod 116 can provide support for the cleaning rod 203 so that it remains stable during reciprocating sliding.

[0034] Wherein, scraping rings 206 that fit the fixing rod 116 are fixedly installed at both ends of the cleaning rod 203 .

[0035] It should be noted that, by providing the scraper ring 206 , impurities attached to the outer wall of the fixing rod 116 can be scraped off when the cleaning rod 203 slides back and forth, thereby preventing these impurities from affecting the normal sliding of the cleaning rod 203 .

[0036] A guide plate 114 for guiding sewage is fixedly installed on one side of the partition 105 , a rotating rod 117 is rotatably installed on the inner wall of the treatment tank 101 , and a plurality of blades 118 are fixedly installed on the outer wall of the rotating rod 117 .

[0037] It should be noted that when sewage flows through the guide plate 114, it will impact the surface of the blade 118, thereby driving the rotating rod 117 and other blades 118 to rotate, which can stir the sewage and fully mix the sewage with the disinfectant to improve the disinfection effect.

[0038] Working principle: When in use, connect the sewage pipe to the water inlet plate 102, the filter 104 can filter the impurities in the sewage, start the motor 204, drive the reciprocating screw 202 to rotate, and then drive the cleaning rod 203 to slide back and forth in the treatment tank 101 through the thread, thereby driving the bristles 205 to rub on the surface of the filter 104, and scrape off the impurities attached to the filter 104, preventing the accumulation of impurities and causing the filter 104 to be blocked, so that the filter 104 can maintain a good filtering effect for a long time.

[0039] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the attached embodiments and their equivalents.
