Abstract
The present invention provides a preliminary screening and separating machine for soil remediation by a leaching method, including a casing, a sieve cage and a slurry pump. The lower part of the casing is equipped with the slurry pump inside, two sides of a rotating shaft of the cylindrical sieve cage are connected to the upper part of the casing by rotating supports on the left and right sides, which shows a rotating state, and one end of the rotating shaft is connected to a speed reducer. The characteristic of the invention is that the left side of the sieve cage is provided with a feed inlet, the right side of the sieve cage is provided with a slag hopper, a layer of screen is provided on the sieve cage, and a blade is provided in the inner wall of the sieve cage. High pressure water is injected in the sieve cage, soil in the sieve cage is repeatedly washed, soluble pollutants and fine particles in the soil are fully separated and brought into a liquid storage case. Since the soluble pollutants and the fine particles are fully separated, the ability of pollution treatment is effectively improved.
Description
Technical field
The present invention relates to environmental pollution treatment apparatus field, be specifically related to a kind of elution method soil remediation primary dcreening operation seperator.
