Description

Scraper for sewage treatment

Technical Field

The utility model relates to a scrape trigger, especially a sewage treatment is with scraping trigger.

Background

At present, the existing scraper conveyor mainly comprises a box body, wherein a driving wheel shaft group and a driven wheel shaft are arranged in the box body, and a plate chain group with scrapers is connected with the driving wheel shaft group and the driven wheel shaft group, a driving motor is arranged on the outer side of the box body, and the driving motor is connected with the driving wheel shaft group through a chain wheel and a chain. After the scraper blade machine breaks down, can lead to driving motor overheated, and then lead to the motor to burn to can lead to mud to pile up, the scraper blade receives too big pulling force to make its crooked unable mud effect of scraping that reaches, probably leads to the sprocket group fracture even, because the accumulational pressure of material can make the whole crooked of scraper blade on the whole plate chain group, so cause the large tracts of land to damage easily. The excessive number of scrapers on the chain plate group can cause overhigh maintenance cost when all the bent scrapers are repaired, and the maintenance cost is directly increased when the bent scrapers are dismantled and new repaired scrapers are installed, so that the serious economic loss can be caused.

Meanwhile, because the equipment of the sludge drying plant is operated in a state of ensuring 24-hour non-stop, if the equipment is damaged and cannot be repaired in time, the normal operation of the equipment is influenced, and the equipment is operated in a way of one loop after another. Due to the damage of the scraper, the materials cannot enter the next step, the materials in the previous step are seriously accumulated, and if the time is too long, the risk of damage caused by the overlarge load of other equipment is easily caused, at this time, the project has to be stopped to prevent the phenomenon, so the normal production is seriously influenced.

The sludge scraper disclosed in Chinese patent 2015103542514 aims at providing a sludge scraper capable of conveying sludge safely and conveniently, and the technical scheme thereof mainly comprises a machine shell, the machine shell comprises an inner space, a discharge port and a feed inlet, the machine shell is divided into an inclined part and a horizontal part, a chain transmission mechanism is arranged in the inner space, the chain transmission mechanism comprises a driving wheel, a driven wheel and a chain, the chain is a plate chain, the other side of a chain plate of the plate chain relative to a chain wheel is fixedly connected with a scraper, polymer lining plates are arranged on the inner space bottom and the two sides of the relative transport direction, a pressure rail is arranged between the inclined part and the horizontal part, and the pressure rail and the plate chain are abutted against the two sides of the plate chain along the transport. The operation load of scraper blade has been alleviateed, and the plate link chain has very high intensity and wearability, because polymer liner plate surface is smooth again, consequently can reduce the material to its frictional resistance, can prevent simultaneously that mud from adhering at the scraper blade, because the corrosion resistance of polymer liner plate is strong, consequently can completely cut off the corruption of mud to the casing and promoted the life of chain. But when the system fails, the system still cannot be stopped in time.
