Description

An intelligent injector that can be rotated at any angle

technical field

The invention relates to the technical field of sewage treatment equipment, in particular to an intelligent ejector that can be rotated at any angle.

Background technique

In the process of urban sewage treatment, various storage tanks will be used. However, a large amount of sediment will be generated in the storage tank during use, so it needs to be cleaned regularly. The traditional cleaning method is to manually flush the bottom of the pool with a high-pressure water gun. However, this method not only has high labor costs, but also has low cleaning efficiency. Therefore, the ejector device for flushing the reservoir was born. The device is usually fixedly installed in the middle of the adjustment tank. When the water level drops to a preset position, the ejector automatically opens to start flushing the adjustment tank, overflow tank, clarifier, etc. It is not only easy to use and flush, but also can purify water, so it is favored by more and more urban environmental protection departments.

However, the existing sprayer mainly uses the electric actuator to rotate the spray pipe to spray and clean the reservoir. Although it can be rotated at a certain angle for cleaning, the cleaning range is relatively limited due to the fixed height. For large pools In general, the sludge at the bottom of the tank cannot be cleaned efficiently, which greatly reduces the efficiency of the ejector. In addition, the water spraying angle of the existing sprayer can only be rotated horizontally, and the three-dimensional and all-round flushing of the pool bottom, the pool wall and even the pool top cannot be performed.

In addition, the ventilation pipe 13 is fixed to the movable cover 22 and can also be rotated together with it.

As shown in FIGS. 3 and 4 , in order to realize the lifting adjustment of the ejector pipe, a first-level ejector lifting mechanism 14 is installed between the rotating arm pipe 6 and the lifting arm pipe 8 . Specifically, the ejector first-level lifting mechanism 14 is installed. It is the first hydraulic oil cylinder. During movement, the lift arm tube 8 can rotate relative to the swivel arm tube 6 .

As shown in FIG. 1 , one end of the ejector secondary lifting mechanism 15 is fixed on the lifting arm pipe 8 , and the other end is hinged with the flange elbow 10 .
