As shown in fig. 1, the present invention provides a rotary drying apparatus for soil remediation, in which an ultrasonic pulverizer 1, a rotary dryer 2, and a centrifuge 3 supplement each other and work in combination. Firstly, soil after soil remediation treatment enters the ultrasonic pulverizer 1 from the funnel-shaped feeding hole 101, a power switch of the ultrasonic pulverizer 1 is turned on, after the soil is subjected to ultrasonic treatment for a period of time, impurities or agglomerates such as stones in the soil are pulverized, the particle size of soil particles is more uniform, and the subsequent heating rotation or centrifugation effect is better. Soil may now be fed through the delivery pipe 102 into the rotary dryer 2.

The rotary dryer 2 is divided into an outer rotary drum 201 and an inner rotary drum 202, and the outer rotary drum 201 and the inner rotary drum 202 share a rotation central axis which is parallel to the ground. 2-4 gear rings 210 are equidistantly installed outside the outer rotary drum 201, a gear base 212 is arranged below each gear ring 210, a driving gear 211 meshed with the gear rings 210 is installed on each gear base 212, a driving motor electrically connected with the driving gear 211 is installed in each gear base 212, the driving motor is started, the driving gear 211 is driven to rotate for a certain time by the driving motor, the gear rings 210 are driven to rotate, the inner sides of the gear rings 210 are fixed on the outer rotary drum 201, and therefore the outer rotary drum 201 and the inner rotary drum 202 are driven to rotate by the rotation of the gear rings 210. In an embodiment of the utility model, the time and direction of rotation is fixed. Firstly, the rotation time of the driving gear 211 is just enough to drive the outer rotary drum 201 and the inner rotary drum 202 to rotate for half a turn simultaneously, so that the spiral blade 205 is positioned right below the inner rotary drum 202, and then the rotation is stopped for 3 to 4 minutes; then, the driving motor drives the driving gear 211 to rotate reversely for the same time, so that the spiral blade 205 returns to the position right above the inner rotating cylinder 202, and then the spiral blade stands still for 3-4 minutes; so be a circulation, set up driving motor pivoted direction and time and can satisfy this circulation, make outer cylinder 201 and interior cylinder 202 regularly rotate periodically like this, can both return the normal position after rotating each time, avoid driving motor and heating resistor 203's power cord winding. It should be noted that the power cord is as long as possible to avoid the risk of short-circuiting or disconnection due to self-winding during rotation. In an embodiment of the present invention, the driving motor is a servo motor. In the embodiment of the present invention, 2 to 4 heating resistance wires 203, preferably 4 heating resistance wires 203, are installed between the outer rotary drum 201 and the inner rotary drum 202. The heating resistance wires 203 are symmetrical relative to the rotation central axis and parallel to the rotation central axis, when the outer rotary drum 201 and the inner rotary drum 202 rotate, the heating resistance wires 203 heat soil in the inner rotary drum 202, the temperature is increased, liquid in the soil is promoted to evaporate, and the effect of drying the soil is achieved. A rotating shaft 204 is arranged between two side surfaces of the upper half part of the inner rotating cylinder 202, a spiral blade 205 is arranged outside the rotating shaft 204, and the rotating shaft 204 is parallel to the heating resistance wire 203. In operation of the rotary dryer 2, the spiral blade 205 rotates with the shaft 204 and changes position with the rotation of the inner drum 202, and can be located anywhere inside the inner drum 202, so as to uniformly roll the soil inside the inner drum 202. The outer surfaces of the shaft 204 and the spiral blades 205 should be as smooth as possible to reduce roughness and reduce the amount of soil hanging thereon. A telescopic rod 207 is installed on the side of the lower half of the inner drum 202 near the feed port 101, and may extend to the other side of the inner drum 202 at the longest. The top of the telescopic push rod 207 is fixedly connected with the center of the push plate 208, and the push plate 208 is pushed by the telescopic push rod 207 to push the soil of the inner rotary drum 202 to the discharge pipe 213 in a static state. A layer of rubber gasket 209 is fixed at the bottom of the push plate 208, the rubber gasket 209 is in direct contact with the inner rotary drum 202, and the rubber gasket 209 is used for reducing friction force and preventing the hard push plate 208 from damaging the inner wall of the inner rotary drum 202.

The height of the spiral blade 205 and the push plate 208 is smaller than the side radius of the inner rotary drum 202, so as to prevent soil from moving during rotary operation and prevent incomplete rotary drying. The position of the cylindrical discharge pipe 213 is fixed and is perpendicular to the ground, the upper left half part and the right side of the discharge pipe 213 are closed, the lower left half part is provided with the rotary retractable door 2132, the rotary retractable door 2132 is closed in the working state of the rotary dryer 2, and the discharge pipe 213 can block the outlet of the inner rotary drum 202 to prevent soil overflow. After the rotary drying operation is completed, the rotary retractable door 2132 is opened, so that the push plate 208 pushes soil into the discharge pipe 213, solids can be discharged from the lower outlet 2133 of the discharge pipe 213, and lighter gases and liquids can be discharged from the upper outlet 2131 of the discharge pipe 213. The inner wall of the discharge pipe 213 is smooth, and each corner of the inner wall is arc-shaped, so that the discharge of soil and gas liquid is smoother, and the loss of soil quantity is reduced.

As shown in fig. 3, the centrifuge 3 is horizontal, and the serpentine 216 connected to the centrifuge 3 makes the soil entering the centrifuge 3 uniform in speed, so as to prevent the soil from flowing into the centrifuge 3 too fast and damaging the equipment. In the embodiment of the present invention, the inclination of the centrifuge 3 is larger than the natural inclination of the soil, and the soil is fed from the higher end and flows into the centrifuge 3 smoothly under the action of gravity. Differential 303 rotates auger feeder 302 to centrifugally move the soil through rotary drying to separate out unwanted liquids and gases and leave the desired soil behind.
