Description

Scraper with purging and oiling functions

Technical Field

The utility model relates to the technical field of scraper machine manufacturing, in particular to a scraper machine with purging and oiling functions.

Background

In the mixing and burning project of sludge drying and thermal power generating units of urban sewage treatment plants, after the sludge is subjected to harmless and reduction drying, the sludge is conveyed to a fire coal system of the thermal power generating units by using a conveying device and is mixed with fire coal for mixing and burning. The conveying device generally uses a scraper or belt conveying equipment, wherein compared with the belt conveying equipment, the scraper has the characteristics of simple and compact structure and good sealing property, can avoid odor emission in the sludge conveying process, and does not need a special cleaning device.

The scraper is made of stainless steel and carbon steel, wherein the cost of the scraper is about 70% lower than that of the scraper made of the carbon steel. Therefore, the scraper machine made of carbon steel has higher cost performance and has higher proportion in industrial application.

However, the scraper machine made of carbon steel has the biggest defects of easy corrosion and rust, particularly a conveying chain, which is always in a severe working environment and bears larger tensile stress, so that the service life of the scraper machine is shorter. In order to prolong the service life of the scraper conveyor conveying chain, the chain needs to be lubricated frequently aiming at the characteristics of the actual working environment for conveying dried sludge so as to reduce the abrasion speed and the rust corrosion rate.

At present, two main modes for lubricating a conveying chain of a scraper machine are as follows: one is to manually lubricate the chain; the other is to lubricate the chain by a oiling device. The chain is oiled and lubricated through the manual work, and because the working environment is poor, the chain length is longer, leads to operation workman's work load big, work efficiency is low, and moreover, has lubricated inhomogeneous, causes the extravagant and poor problem of lubricated effect of lubricating oil. In addition, the existing oiling device is adopted to lubricate the chain, and as the chain is usually stuck with mud, the chain is directly added with lubricating oil, so that the chain is easy to be stuck with mud, and finally the problem of poor chain lubrication effect is caused.
