Description
Technical Field
The invention relates to an anti-fishing grid, in particular to an anti-fishing grid with an anti-slag removing device.
Background
The grids are mechanical equipment commonly used in sewage treatment plants and are divided into coarse grids and fine grids according to the use function. The existing more used thick grids include reverse fishing type, rotary type, high chain type and three-rope type. The coarse grating is used in domestic sewage treatment plants, and the reverse fishing grating is used in many cases. The reverse fishing grid has the advantages of more thorough slag fishing and low failure rate, so the reverse fishing grid is widely applied. The anti-fishing grid mainly comprises a rack, a drag chain, a driving device, grid bars, rake teeth and the like, wherein the rake teeth are fixed on the chain, the drag chain is driven by a motor to run along a guide rail through a speed reducer and a transmission chain, the rake teeth run downwards from the rear part of the grid bars to the bottom of the grid bars under the drive of the drag chain, and run upwards from the bottom of the grid bars to the front part of the grid bars through a guide wheel, the rake teeth are inserted into gaps for fixing the grid bars at the positions facing the water surface in front of the grid bars, so that dirt intercepted in front of the grid bars is lifted out of the water surface and automatically overturned at the position of a slag outlet along with the motion of the drag chain, and the dirt is automatically unloaded into a conveyor or a slag barrel behind the grid, and. However, when the anti-fishing grid operates, some soft objects such as plastic bags and ropes can be adsorbed on the rake teeth, so that the anti-fishing grid is not easy to drop automatically at a slag hole, can enter water again along with the operation of the rake teeth, repeatedly pollutes water sources, and can cause pump station blockage, and damage is large.
Disclosure of Invention
Aiming at the defects, the invention aims to provide the reverse dredging grid with the reverse slag removing device, which has a simple structure, can effectively remove dirt on the rake teeth, improves the dirt removing efficiency of the reverse dredging grid, and protects the lower-level pump station.
Therefore, the technical scheme adopted by the invention is as follows:
including drag chain, gyration rake teeth mechanism, the frame of slope setting in the irrigation canals and ditches, the frame upper end is equipped with the drive variable speed system that the drive drag chain revolved, and gyration rake teeth mechanism both ends are connected with the drag chain, the below of frame upper end is equipped with anti-scarfing cinder device, anti-scarfing cinder device is including anti-scarfing cinder pole, connecting plate and frame fixed connection are passed through at the both ends of anti-scarfing cinder pole, be equipped with a plurality of anti-scarfing cinder teeth on the anti-scarfing cinder pole, the tip of anti-scarfing cinder tooth is located the inside and crisscross setting with the rake teeth of gyration rake teeth mechanism, and frame upper portion is equipped with the device that sweeps that is located the drag chain top, sweep the device and include air compressor machine, trachea and set up the nozzle at trachea tip, the.
As a further improvement of the technical scheme, the included angle between the inclined surface at the upper end of the back slag removal tooth and the vertical plane is 20-40 degrees.
As a further improvement of the technical scheme, the air compressor is provided with a control valve for controlling the opening and closing degree of the air pipe.
As a further improvement of the technical scheme, a hard alloy layer is arranged on the surface of the back scarfing cinder tooth.
The invention has the advantages that:
the reverse cleaning device is simple in structure, the reverse cleaning teeth of the reverse cleaning device can reversely clean the rake teeth of the rotary rake tooth mechanism by additionally arranging the reverse cleaning device below the upper end of the rack of the reverse fishing grid, dirt on the rake teeth can be effectively cleaned, and the effect of cleaning the dirt on the rake teeth can be further improved by additionally arranging the blowing device, so that the dirt removing efficiency of the grid is improved, the service life is prolonged, and a lower-level pump station is better protected.
