Description

A sedimentation tank sludge discharge device

technical field

The utility model relates to the technical field of industrial water treatment.

Background technique

The radial flow sedimentation tank is a treatment facility widely used in water treatment. It uses a mud scraper to scrape the sludge at the bottom of the sedimentation tank to the sludge pit in the center of the sedimentation tank, and then pumps the sludge away through the slurry pump. Due to the serious scaling phenomenon in the sedimentation tank for acid water treatment, after the scaling on the wall of the tank falls off, there are large hard scales. When the mud scraper scrapes the large hard scales in the sedimentation tank into the mud pit in the center of the sedimentation tank, it is easy to cause sludge discharge Pipes and mud pumps are clogged, and dredging is difficult. It is necessary to drain the water in the sedimentation tank and exit the sedimentation tank before dredging. On the one hand, it will affect the normal operation of the water treatment system, and it will also bring difficulties to maintenance.

Contents of the invention

The purpose of this utility model is aimed at above-mentioned shortcoming exactly, has designed a kind of sludge discharge device of sedimentation tank.

The technical scheme of the utility model is achieved in the following way: a sedimentation tank mud discharge device, characterized in that: it includes a mud scraper, a sedimentation tank, a mud collection pit, a tee with different diameters, a first valve and a second valve, and the mud scraper A sedimentation tank is arranged below the pool, and a mud collection pit 33 is arranged below the sedimentation tank. A different-diameter tee is arranged below the mud-collection pit. The first valve is arranged on the outlet pipe of the different-diameter tee vertically downward, and the different-diameter tee is horizontal. A second valve is arranged on the facing outlet pipe, and the outlet end of the horizontally facing outlet pipe is connected with a slurry pump.

Further speaking, the diameter of the vertically downward outlet pipe is 600-650mm, and the length is 2m-2.5m.

Further speaking, the diameter of the horizontal outlet pipe is 300-350mm.

Further speaking, the distance between the first valve and the second valve is 200-300mm.

The utility model can reduce the clogging of the mud discharge pipe of the sedimentation tank, and at the same time, even if the mud discharge pipe of the sedimentation tank is blocked, it is not necessary to empty the sedimentation tank and exit the sedimentation tank, and the maintenance can be performed online, and the maintenance difficulty is reduced ,save human effort. It does not affect the normal operation of the system and prolongs the service life of the mud discharge pump. After using the utility model, the failure of the mud discharge pipe blockage has been successfully dealt with for many times, about 2 times per year on average.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described further.

As shown in the figure, a sludge discharge device for a sedimentation tank is characterized in that it includes a mud scraper 1, a sedimentation tank 2, a mud collection pit 3, a different diameter tee 7, a first valve 4 and a second valve 5, and the mud scraper A sedimentation tank 2 is arranged below the pool, a mud collection pit 3 is arranged below the sedimentation tank 2, a different-diameter tee 7 is arranged below the mud-collection pit 3, and a first valve 4 is arranged on the vertically downward outlet pipe of the different-diameter tee 7 A second valve 5 is provided on the horizontally facing outlet pipe of the reducing tee 7, and the outlet end of the horizontally facing outlet pipe is connected to the slurry pump 6 for discharging the sludge at the bottom of the sedimentation tank 2. Make the vertically downward outlet pipe thicker by 100mm and lengthen by 1.5-2m. Specifically, the diameter of the standpipe can be determined according to the size of the sedimentation tank 2 and the size of the debris. The larger the debris, the more the diameter and length of the standpipe can be increased accordingly. Speaking, the distance between the two valves should be shortened as much as possible, and the 6 mud inlet pipes of the mud discharge pump are installed in front of the first valve 4 of the sedimentation tank 2 mud discharge pipes.

During normal operation, the first valve 4 of the sludge discharge pipe of the sedimentation tank can be opened, and the second valve 5 of the sludge discharge pipe of the sedimentation tank can be opened. 3, when entering the mud discharge pipe, the sundries or hard dirt can settle down to the second valve 5 of the mud discharge pipe by gravity, so as to prevent the mud discharge pump 6 from being pumped to the mud discharge pipe of the pump 6, causing the pipe or pump 6 to be blocked and affecting Sludge discharge, damage to equipment.

During maintenance and cleaning, the first valve 4 of the sludge discharge pipe of the sedimentation tank can be closed, and the second valve 5 of the sludge discharge pipe of the sedimentation tank can be opened to discharge the sundries and hard scale to the ground, and manual cleaning is enough without affecting the normal operation of the system operation, reduce maintenance difficulty and safety risks, and prolong the service life of the mud discharge pump 6 . By adopting a new type of sedimentation tank sludge discharge device, the occurrence of blockage of the sedimentation tank sludge discharge pipe can be reduced. The debris at the outlet of the sedimentation tank sludge discharge pipe can be checked and cleaned by regularly operating the valve. At the same time, even if the sedimentation tank sludge discharge pipe is blocked, There is no need to empty the sedimentation tank and exit the sedimentation tank, and the maintenance and treatment can be carried out online, which reduces the difficulty of maintenance, saves manpower, does not affect the normal operation of the system, and prolongs the service life of the sludge discharge pump.

The above is only a specific embodiment of the utility model, but the structural features of the scope of protection of the utility model are not limited thereto, any changes or modifications made by those skilled in the art within the scope of the utility model are all covered in Within the patent scope of the utility model.
