    • 专利摘要:
    The invention relates to a special protective structure for an aerator. In small wastewater treatment plants and dust aerators, immersion is required and a structure that protects the aerator in wastewater treatment plants for a sludge discharge pipe. The aerator's protective structure makes it possible to lift the aerator out of a wastewater or water bed and the aerator can be removed from the protective structure without the use of tools.

    air housing
    Various aerators are generally used for wastewater treatment and water aeration. In large objects, the aerators are weighted to the bottom of the water mattress with absorber plates or piping to which the aerators are screwed or otherwise secured. In smaller objects, such as small treatment plants, the aerators are similarly weighted with different fixed weights or racks where the aerators are attached so that the aerator cannot be removed from the rack without disconnecting it from the aeration hose or one end. Garden pool aerators are weighted accordingly. Loose aerators in use are lifted out of the water by their aeration hose. Some aerators are instructed to remove sludge and wastewater from the sewage treatment plant tank during emptying / removal. Sludge and wastewater are known to be removed from the tanks by a sludge truck, which sucks the sludge and wastewater from the bottom of the wells with a hose. If the suction hose hits the surface of the aerator, the aerator will break and must be replaced. The known detachable racks do not completely prevent the breakage of the suction hose from occurring.
    The aerator housing can be used to weight individual aerators to the bottom of the water mattress or sewage mattress, and the invention makes it easy to lift the aerator out of the water with a hoisting rope attached to the aerator housing. In this case, the air hose of the aerator and the joints (spindle and fasteners on the hose) are not subjected to stress, so that the risk of its breakage when lifting the aerator is eliminated. When the aerator housing is used in wastewater, cleaning the surface of the aeration plate can be performed in a more convenient manner when the aerator does not need to be removed from the threads and spindle of the hose head to get it out of the housing. The aerator and the upper sides of the bars or grids slots are therefore smaller, the lietetyhjennysietku does not touch the surface aerator. The surface of the aerator is normally thin and micro-perforated rubber that is easily broken by sharp objects or a hard hit. When using the housing according to the invention, the aerator does not have to be lifted out of the process tank during the sludge emptying of the waste water while at the bottom of the mattress.

    The aerator needs a holder or housing with which it is weighted to the bottom of the water mattress, because the aerator is lifted when air is pumped into it under pressure and then the aerator does not stay at the bottom but rises to the surface. With a sufficiently heavy housing or weight, the aerator is weighted to the bottom.
    The advantages of the invention, i.e. the aerator housing, are the easy pleasant maintenance of the aerator and the easy emptying of the tanks and wells, as well as the removal of the stress on the aerator hose from the aerator lifts and landings. The aerator housing can also be used as a weight with pond aerators.
    The upper surface of the aerator housing has transverse bars, one of which is longer and at an upward angle so that a lifting rope can be attached to it. The edge of the circular housing may be made of or closed from a closed plate, as shown, but in such a way that the sludge drain hose cannot hit the surface of the aeration plate also through the edges of the housing. The housing may rest on the base on three or more legs, or the legs may cross each other. The applicator plate is placed in the housing from below by lifting one edge of the aerator onto the housing rod (8) and inserting the other edge into the housing with the housing release (5). In addition, rods (9) or other clamps or projections are attached to the edges of the housing so that the aerator remains in the housing at the level designed to prevent it from rising to the top surface in the housing due to buoyancy. The suction plate is removed from the housing by lifting off the holder (5), so that the aerator can be lowered from the edge of the holder below the aerator housing.
