Abstract

A fast harmless treatment device for a hazardous flexible material is provided. The fast harmless treatment device includes a container body and a container lid, where a bottom plate is fixed at a near-bottom position of the container body; a movable plate is provided in the container body; there is a gap between an outer edge of the movable plate and an inner wall of the container body; a movement mechanism is configured to compress a hazardous flexible material on the movable plate towards the container lid; the container lid and the movable plate each are provided therein with a heating tube; and a heating tube and a blowing device are provided on the bottom plate to cause high-temperature convection and disinfect an aerosol-mixed gas.

Claims (8)

1 . A treatment device for a hazardous flexible material, comprising a container body and a container lid, wherein a bottom plate is fixed at a near-bottom position of the container body; a movable plate is provided in the container body, wherein the movable plate is controlled by a movement mechanism to move up and down; a gap is formed between an outer edge of the movable plate and an inner wall of the container body; and the movement mechanism is configured to compress a hazardous flexible material on the movable plate towards the container lid and cause an aerosol-mixed gas generated after compression to flow down along the gap between the movable plate and the inner wall of the container body;

the container lid is provided therein with a first heating tube and the movable plate is provided with a second heating tube for performing high-temperature disinfection on the hazardous flexible material in the container body, concurrently with compression of the hazardous flexible material; and a third heating tube and a blowing device are provided on the bottom plate to cause high-temperature convection in a chamber between the movable plate and the bottom plate and disinfect the aerosol-mixed gas generated after the compression of the hazardous flexible material;

the movement mechanism comprises two linear motors vertically fixed to an inner bottom surface of the container body and two screw rods with respective lower ends connected to output shafts of the two linear motors and upper ends rotatably fixed to a fixing ring, wherein the fixing ring is provided at an upper end of the container body; the two linear motors synchronously drive the two screw rods through a transmission assembly, causing the two screw rods to rotate synchronously; two guide rods are provided between the inner bottom surface of the container body and the fixing ring, wherein the two guide rods runs through the movable plate; the two screw rods and the two guide rods are evenly and alternately arranged along a circumference of the movable plate; the movable plate is matched with the two screw rods through internally threaded screw rod sleeves; and the two screw rods are driven by the two linear motors to move the movable plate up and down along the two guide rods; and the blowing device comprises a motor and a blade; the motor is sealed and fixed at a center of a lower end surface of the bottom plate; and an output shaft of the motor passes through the bottom plate and is connected to the blade above.

2 . The treatment device for the hazardous flexible material according to claim 1 , wherein a control panel is provided outside the container body, for controlling heating of the first heating tube, the second heating tube, and the third heating tube, an up-down movement of the movable plate, and an on-off of the blowing device.

3 . The treatment device for the hazardous flexible material according to claim 1 , wherein a lower surface of the container lid, an upper surface of the movable plate, an upper surface of the bottom plate, and an interior of the container body are provided with temperature sensors; the temperature sensors are monitored through a control panel in real time; and a proportional-integral-derivative (PID) control module is combined to achieve automatic temperature control and maintaining a constant temperature over a targeted period of time.

4 . The treatment device for the hazardous flexible material according to claim 1 , wherein an outer bottom surface of the container body is provided with a plurality of swivel casters.

5 . The treatment device for the hazardous flexible material according to claim 1 , wherein the container lid is provided with a clamshell structure; the container lid is fixed to a sealing flange provided at the upper end of the container body through a fastener; and the container lid is provided with an opening handle.

6 . The treatment device for the hazardous flexible material according to claim 1 , wherein the container body is a cylinder or square column in shape; and the inner wall of the container body is provided with an insulation layer.
