Description

A multi-functional automatic mud suction and scraper

technical field

The utility model relates to the technical field of sewage treatment devices, in particular to a multifunctional automatic mud suction and scraper.

Background technique

At present, in the sedimentation unit of sewage treatment, it is necessary to collect the precipitated sludge and use the biological process to treat the sewage. It needs to return a part of the sewage to the biological pool of the previous process of sedimentation, and the remaining sludge is dehydrated and transported outside. Among them, the higher the activity of the sludge returned to the biological pool, the better the effect on sewage treatment. Therefore, in order to maintain the activated sludge in the biological pool to a certain concentration, it is still necessary to return the activated sludge to the biological pool. In the process of sewage treatment, sludge with high activity is easy to deposit in the middle of the sedimentation tank, and inert sludge is easy to deposit in the bottom of the sedimentation tank. How to separately collect the activated sludge and inert sludge in the sedimentation tank has become a common concern at present, but there is no corresponding equipment yet.

Utility model content

The technical problem to be solved by the utility model is to provide a multi-functional automatic suction and scraper for the deficiencies in the above-mentioned prior art, which uses the principle of siphon to suck out the sludge or sediment deposited at the bottom of the pool through the suction box , lift, and then discharge out of the pool; or scrape the sludge at the bottom of the pool to the central mud tank at the bottom of the pool, and use water pressure to discharge it out of the pool through pipes, so as to achieve the purpose of separating solid substances in the water.

The suction box adopts an inverted funnel-shaped structure, and its lower end has a toothed structure. The lower end of the suction pipe is installed on the suction box, and the upper end of the suction pipe is installed on the bridge. The mud scraping device at the bottom of the pool is connected to the bridge frame through a pull rod. When the bridge frame rotates around the center of the pool, it drives the mud scraping device at the bottom of the pool to scrape the remaining sludge at the bottom of the pool to the central mud groove at the bottom of the pool. The outlet weir plate is Circumferentially installed on the outlet channel, the outlet weir plate is provided with triangular weir teeth, and the scum baffle is installed in a circular shape on the side of the pool higher than the top of the outlet channel, and the scum scraper is installed under the bridge frame and its The lower end is immersed in water, the scum funnel is fixedly installed on the wall of the outlet channel, the upper mud outlet pipe is installed on the central axis of the central pillar, and the lower mud outlet pipe is installed in the bottom of the pool.

As a preference, the drive assembly is composed of a motor, a shaft-mounted worm gear reducer, a driving wheel and a driven wheel, the motor is mounted on the shaft-mounted worm gear reducer, and the driving wheel is mounted on the shaft-mounted worm gear reducer On the output shaft, the driven wheel meshes with the driving wheel, and the driven wheel is installed on the bottom surface of the right end of the bridge frame.

Preferably, the central pivot bearing adopts a cross roller slewing bearing.

Preferably, the vacuum pumping system is composed of a vacuum pump, a vacuum safety valve, a water eliminator and a main vacuum pipeline with several branches.

The suction mud scraper is installed on a circular sewage sedimentation tank (the diameter of the tank body can reach tens of meters), and it rotates around the center of the tank. Using the principle of siphon, the sludge or sediment settled at the bottom of the pool is sucked out through the suction box, lifted, and then discharged out of the pool; It is discharged out of the pool through the pipeline, so as to achieve the purpose of separating solid substances in the water.

Compared with the prior art, the utility model has the following advantages: the overall structure is simple, easy to realize, and easy to operate; a pressure relay is arranged on each suction pipe to monitor the pressure in the pipe, and when the vacuum degree in the pipe decreases, the pressure rises to reach the set value. When the pressure reaches the upper limit, the pressure relay will act, triggering the solenoid valve installed on the air branch connected to each suction pipe in the vacuum system to conduct, and the vacuum pump to start the suction system, so as to realize automatic control of the vacuum pump on and off, and ensure the suction of the mud scraper. The purpose of stable work and reducing labor intensity; it has the advantages of sufficient strength and long life.
