Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to sludge collecting equipment for sewage treatment. Background Art

[0002] In the sewage treatment process, sludge collection is an important link. It involves effectively separating the sludge generated during the treatment process from the water body for subsequent treatment and disposal. Sewage treatment can effectively reduce environmental pollution, and the re-treated water can even be used again for production and life. Sewage treatment will precipitate a large amount of sludge during aeration. This sludge needs to be collected and treated regularly to facilitate the reuse of the aeration tank.

[0003] However, after the sewage is aerated in the existing aeration tank, it flows from a fixed outlet to the next treatment equipment, resulting in a certain amount of sludge being carried by the water flow. This not only reduces the sewage treatment efficiency but also makes the sludge that flows away difficult to collect again. In order to avoid the above technical problems, it is indeed necessary to provide a sludge collection device for sewage treatment to overcome the above defects in the prior art.

An aeration chamber is opened inside the aeration tank 1. The water pressure plate 206 is slidably connected to the aeration tank 1 through the aeration chamber to prevent water surface fluctuations.

[0032] A funnel 207 is welded to the bottom end of the aeration tank 1, and a sludge pipe 208 is welded at the middle position of the bottom end of the funnel 207. A discharge trough is opened at the bottom end of the funnel 207, and the sludge pipe 208 is connected to the chamber inside the funnel 207 through the discharge trough, so as to facilitate the rapid discharge of sludge. A solenoid valve 209 is sleeved on the outside of the sludge pipe 208, and a water pump 210 is installed at the middle position of the water pressure plate 206. The top of the water pump 210 is connected to a water hose 211. A mounting plate 212 is installed on one end face of the aeration tank 1, and a water outlet pump 213 is installed on the top of the mounting plate 212. The water outlet end of the water outlet pump 213 is connected to a drain pipe 214, and one end of the water hose 211 is connected to the liquid inlet end of the water outlet pump 213 to quickly separate the sewage. The input ends of the hydraulic cylinder 203, the solenoid valve 209 and the water outlet pump 213 are all electrically connected to the output end of the external power supply.

[0033] A cleaning assembly 3 is installed on the top of the water pressure plate 206;

[0034] The cleaning assembly 3 includes a clamping hole 301, a nozzle 302, a water distribution ring pipe 303, a cleaning water pump 304, a cleaning hose 305 and a water inlet pipe 306;

[0035] A snap-in hole 301 is provided on the inner side of the water pressure plate 206, and a nozzle 302 is embedded in the inner side of the snap-in hole 301. The water inlet end of the nozzle 302 is connected to the water diversion ring pipe 303. A cleaning water pump 304 is installed on one end face of the aeration tank 1. The water outlet end of the cleaning water pump 304 is connected to a cleaning hose 305. The water inlet end of the cleaning water pump 304 is connected to the water inlet pipe 306. There are several nozzles 302, and several nozzles 302 are welded at the bottom of the water diversion ring pipe 303 at equal angles. The water outlet end of the cleaning hose 305 is connected to the water diversion ring pipe 303, which is convenient for cleaning residual sludge. The input end of the cleaning water pump 304 is electrically connected to the output end of the external power supply.

[0036] The working principle and use process of the present invention are as follows: first, the sewage to be treated is directed into the interior of the aeration tank 1, and then aeration and sedimentation are performed. At this time, a large amount of sludge will settle at the bottom of the aeration tank 1. After a period of use, a large amount of sludge will settle at the bottom of the aeration tank 1. At this time, the outlet pump 213 is turned on, and a large amount of sewage will be pumped from the suction pipe 210 into the interior of the water supply hose 211, and then enter the inner side of the outlet pump 213 from the water supply hose 211, and then discharged from the drain pipe 214 to the next treatment measure;

[0037] At this time, when sewage is continuously extracted, the hydraulic cylinder 203 inside the mounting sleeve 202 is controlled to retract, thereby driving the connecting plate 204 and the lifting rod 205 to move downward. When the lifting rod 205 moves downward, it drives the water pressure plate 206 and the water extraction pipe 210 to move downward, extracting sewage from top to bottom. At this time, a large amount of sludge settles inside the funnel 207, so that the sludge will not be stirred when the sewage is slowly extracted.

[0038] When the water pressure plate 206 contacts the top of the sludge, pumping stops. At this time, the sewage and sludge are completely separated. The operator can then place the container at the bottom of the sludge pipe 208 and open the solenoid valve 209 to recycle the sludge. This ensures that no sludge remains in the aerated water, maximizing the sludge recovery, making it easier to reuse and saving energy, thus achieving multiple goals and protecting the environment.

[0039] Then, after the sludge recovery is completed, the cleaning water pump 304 can be turned on to allow the external water source to be passed into the cleaning hose 305 through the water inlet pipe 306, and then enter the inner side of the water distribution ring pipe 303 through the cleaning hose 305, and then be evenly distributed to the nozzle 302 through the water distribution ring pipe 303, and finally the top of the funnel 207 is flushed through the nozzle 302 to clean the residual sludge, thereby preventing the residual sludge from mixing with the next batch of sewage for different purposes, thereby ensuring that different types of sludge are separately recovered.

[0040] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
