Abstract

The invention relates to a soil drying and screening device, in particular to a screening machine for town spoil sampling analysis. The screening machine for town spoil sampling analysis comprises a machine body, a feeding hopper is arranged on the top of the machine body, crushing rollers are symmetrically arranged on the lower part of the feeding hopper, an air cylinder is internally arranged onthe top of the machine body, a flow distributing plate is arranged at the output port of the air cylinder, supporting plates are fixedly connected with the inner wall of the machine body, the supporting plates are evenly connected with springs and straight rods, the straight rods are slidably connected with a filter plate, a vibration exciter is fixedly mounted at the center of the bottom of thefilter plate, a baffle and guiding plate are arranged on the right side of the filter plate, hot air tubes are evenly arranged below the supporting plate, a transmission belt is arranged below the hotair tubes, a collection hopper is arranged on the left side of the transmission belt, spray tubes are evenly and fixedly arranged on the side wall of the lower part of the collection hopper of the machine body. According to the screening machine for town spoil sampling analysis, a first screening is conducted through the vibration exciter driving the filter plate to shake, effective materials fall on the transmission belt, then a second winnowing is conducted through a electric hot air machine and the spray tubes, so that the screening effect of the device is good, and meanwhile the materialsfalling in a concentrating mode is convenient for the spray tubes screening by designing the collection hopper.

Description

technical field [0001] The invention relates to soil drying and screening equipment, in particular to a screening machine for sampling and analyzing urban waste soil. Background technique [0002] With the acceleration of economic development and urbanization, the total amount of demolition of existing buildings and engineering construction continues to increase. With the promulgation and implementation of various laws and regulations on the protection of cultivated land and environmental protection in our country, how to deal with and discharge construction waste has become an important issue faced by construction enterprises and environmental protection departments. Construction waste is also called urban spoil. [0003] Urban spoils are classified into sandy soil, silt soil and cohesive soil according to the particle size range. Through the analysis of the physical and chemical properties of different types of spoils, a proper disposal method is put forward. [0004] T...
