I. Introduction
In the current treatment process, the coarse grid equipment used to remove suspended solids, high chain grate discharge machine, the traditional rope traction grate discharge machine and so on. The operation of these devices easy to impurities muddy, is not completely clear, and the crushing of impurities easy to run from the grille drain, or winding easy to plug in the grille gate gap. Encounter pieces of wood and bamboo poles, tree branches and other hard objects, easy to equipment stuck or damaged equipment, wire rope traction grate discharge machine chaos rope may also occur. Separation, low efficiency, does not operate properly.
Given the shortcomings of the above grill in use, the company developed the rotary rain grille, the device is a continuous automatic remove suspended solids in the liquid device, and its frame structure with reference to the rotation of my company the advantages of the rain grille with distinctive works that rake tooth chain around the trash rack for rotary motion, when the rake teeth running to the positive side of the trash rack, chain harrow teeth in a closed, vowed not to allow debris intrusion, to make equipment run more smoothly. Machine lifting equipment installation, and embedded on the horizon of the collection wells on both sides of 620 × 150 × 16 steel plate two, civil engineering, saving, easy installation and maintenance.
The device design is reasonable, simple, operate safe, reliable, high degree of automation, can be widely used in water treatment industry.
Second, the principle
Rotary rain grill rack, variable speed drive systems, transmission guide wheel, wheel bearing and rotating around its closed rotary traction chain, tooth rake and trash rack. The driver of the motor reducer, the rotary traction chain for rotary motion from bottom to top, from bottom to top in the gap when the drag chain harrow teeth axis running to the positive side of the trash rack, harrow teeth, insert trash rack clear fishing action, the retention of debris on the trash rack scraping off the rake. An angle between teeth due to tooth harrow design double gear tooth harrow, so that when a tooth inserted into the trash rack cracks in the clear fishing, another tooth with the formation of bound to solid surrounded by the debris surrounded, without their lacuna, The high removal efficiency and thorough. Tooth harrow operation to machine the upper part of the debris by weight on their own off the container or conveyor, sent away the debris.
At the same time taking into account at design time:
1, the debris may enter the traction chain, will lead the chain stuck, so the design of a closed traction chain.
2, underwater bearing components made of stainless steel, together with the wear-resistant steel bearings, eliminating the need for routine maintenance of the underwater components.
Third, the characteristics and conditions of use
1, rotary rain grille, trash rack placed in the middle position of the drag chain harrow teeth (other mechanical grid placed under traction chain), and change the direction of movement of the rake teeth clear fishing (and other grille on the contrary ) to avoid a hard object into the bottom of the tooth harrow and drag chain stuck.
2, the device uses a rotary traction chain, its main chain plate chain pin and roller composition. Run by the rail on the rack-oriented roller for rolling movement on the rail, which eliminates the trouble of wire rope traction the chaos rope of the grate discharge machine.
3, this device can be based on the user needs to be adjusted device running interval, periodic operation, according to the gate before the gate level difference of automatic control and manual control functions, easy maintenance.
4, in order to avoid the impact load damage to the equipment, the reducer output shaft shaft sprocket plate design and installation of overload safety protection device.
In short, the rotary rain grille with a high degree of automation, clear fishing effect, less power consumption, no noise, good corrosion resistance, etc., in the case of unattended, can ensure continuous and stable, routine maintenance work rarely. Can be widely used in municipal sewage treatment, water treatment place of the water intake of the waterworks, and storm water pumping station, power plant cooling water intake point.
