Description

Rotary rake type grating decontamination equipment

Technical Field

The utility model relates to a sewage treatment technical field, concretely relates to gyration rake type grid scrubbing equipment.

Background

The rotary rake type grid cleaner is a special water treatment equipment capable of continuously and automatically intercepting and removing various shaped sundries in fluid, can be widely applied to urban sewage treatment, tap water industry and water inlets of power plants, and is one of more advanced solid-liquid screening equipment.

The existing rotary rake type grid sewage removing machine has the following two structures: firstly, adopting an annular rake tooth net belt to salvage slag; secondly, a rake tooth mechanism arranged on the chain belt at intervals is adopted to salvage the slag. Referring to fig. 1-2, there is shown a schematic view illustrating an operation of a conventional rotary rake type grid sewage removing machine of a second structure. When the speed reducer motor 1 is electrified, the sleeve roller chain 2 is driven by the chain wheel to do rotary motion around the grid body, the toothed harrow 4 is connected with the roller chain 2, the toothed harrow 4 also does rotary motion around the grid body along with the sleeve roller chain 2, the auxiliary grid 6 is pushed open by the toothed harrow 4 when the toothed harrow 4 runs to the lower part of the equipment and rotates backwards and moves upwards through the guide device 7, the auxiliary grid 6 is erected on the main grid 9 under the action of self gravity after the toothed harrow 4 continues to move upwards to be separated from the auxiliary grid 6, impurities intercepted by the main grid and the auxiliary grid can be separated from liquid along with the upward movement of the toothed harrow 4, and the toothed harrow 4 runs to the upper part of the equipment and rotates backwards through the guide device and then falls into the aboveground garbage truck 5 by self weight. The rotary type grating is fixed on the civil engineering through a support 3. The structure is ingenious in design and high in garbage fishing efficiency, but the following use defects still exist in the use process:

first, the inclination angle of the frame after being inserted into water can not be adjusted. The frame of the rotary rake type grid sewage-cleaning machine usually comprises two side plates which are oppositely arranged and are respectively used for mounting a transmission chain mechanism, a main grid and an auxiliary grid. The sewage flows in from the front sides of the two side plates, then the sewage flows out from the back sides of the two side plates after the garbage is captured by the grid bodies. Most manufacturers do not usually provide a bottom plate at the bottom of the two side plates when manufacturing the frame, but only a rectangular opening, while the bottom of both side plates are arranged to be inclined so that the frame can be maintained at a certain stable inclination angle when mounting the equipment to the bottom of the wastewater tank. The reason for not setting the bottom plate is to prevent the accumulation of sundries such as silt and the like at the bottom of the water, thereby increasing the weight of the equipment and causing troubles for taking out the equipment. Therefore, in the design, the installation angle of the equipment can only depend on the manufacturer, and the user cannot adjust the installation angle, so that great limitation is brought to the use of the user.

Secondly, the gaps of the auxiliary grids are easy to block, and the flow rate of sewage is influenced. When the rake teeth run to the lower part of the equipment and reversely move upwards through the guide device, only the front end gap of the auxiliary grate can be swept, but the rear end gap of the auxiliary grate cannot be swept, so that the bottom of the equipment (namely the rear end of the auxiliary grate) is particularly easy to be blocked by dirt, and the sewage flow is influenced to a certain extent. And there is a problem that the equipment is difficult to be taken out.

Thirdly, sundries are easy to adhere to the upstream surface of the main grid body and gaps among the grids of the main grid body in the long-time use process, and equipment needs to be taken out periodically for cleaning. Because the main grid body is designed by adopting a rectangular plate, and the rake tooth rods have a certain distance from the upstream surface of the rectangular plate, when the inclination angle of equipment installation is not large or the water flow is smooth, impurities are easily accumulated on the upstream surface of the main grid body after a long time. And because the lower rake teeth are fixed in the path of the gap of the main grid body, the region where the grid gap is not cut is easy to accumulate stubborn dirt, and impurities are accumulated to increase the weight of the equipment, so that the difficulty of removing the equipment is increased when the equipment needs to be removed.
