It can also be fixedly connected fasteners such as screws with the casing or neck connection is by way of mode connects for screw is combined, to carry
High-stability；
Wherein, above-mentioned screening case 1 can only set one, can also be set to multiple and be connected in the form of series connection, sieve case 1
Particular number can flexibly be selected according to the different of pollutant concentration etc., it is ensured that rehabilitating soil is up to standard；
Moreover, the mesh size of the screen cloth 17 can be uniformly distributed, can also be distributed with becoming larger from high to low,
So as to improve migration time of the soil on screen cloth 17, increase soil and air flow contacts time；
Feeding conveyor 5, it is connected with the higher end of the screen cloth 17, contaminated soil is provided to screen cloth 17；In order to prevent
Contaminated soil volatilizes organic gas, closed on the feeding conveyor 5 to have protective cover 6；
Sieving frame 8, it is connected by vibrating spring 9 with the screening case 1, vibrating motor is provided with the screening case 1
7, pass through effect of vibration so that the relatively fine earth earth on the screen cloth 17 is fallen on the bottom surface of the casing, and is caused described in stop
Thicker soil on screen cloth 17 moves from high to low with the relatively fine earth earth on the bottom surface of the casing；
Bulky grain soil outfeed belt conveyor 16, connect with relatively low one end of the screen cloth 17；
Little particle soil outfeed belt conveyor 15, connect with relatively low one end of the bottom surface of the casing；
Hot-air system 3, connected by flexible conduit with air inlet 10 of the casing side close to bottom in flexible encapsulated,
To provide thermal current into casing；
Draft hood 2, the top surface airtight connection with the casing, and pass through the pump-line 11 and exhaust treatment system of flexibility
