With the accumulation of floating pollutants in the well, unpleasant and toxic gases are generated in the abandoned flow well, affecting Surroundings. Therefore, a slag removing device is needed to intercept pollutants such as floating matter, sediment and suspended matter carried in rainwater and sewage, so that when rainwater and sewage pass through the slag removing device, a large amount of pollutants are intercepted, so that various processing devices entering the drainage system are obtained. The rainwater and sewage are relatively clean, effectively avoiding the odor problem of the abandoned flow well, and can effectively prevent the clogging.

As a key part of the slag removal device, the slag filter screen and the filter frame need to have the characteristics of stable connection at work and easy disassembly when replacing the slag filter.
