Reaction device for comprehensive determination of biodegradability of materials and its method of use

A reaction apparatus for comprehensively measuring biodegradability of a material, wherein it comprises:

• a device frame;
• an electrical control cabinet, which is arranged on the device frame, wherein a control panel is installed on a surface of the electrical control cabinet, and a programmable logic controller is provided inside the control panel;
• a plurality of reaction chamber monomers arranged on the device frame, wherein each of the reaction chamber monomers is respectively connected to the electrical control cabinet, and the reaction chamber monomers are independent of each other and are respectively controlled by the electrical control cabinet, wherein the reaction chamber monomer comprises:
• a reaction chamber body, which is arranged on an upper side of an inside of the reaction chamber monomer, wherein the top of the reaction chamber body is sealed by a chamber cover, materials required for measurement can be put into the reaction chamber body after the chamber cover is opened, an electric heating plate and a thermal insulation cotton are attached to a side wall of the reaction chamber body, the electric heating plate is controlled by the electrical control cabinet to adjust the temperature in the reaction chamber body;
• and the bottom of the reaction chamber body is provided with a discharge port for discharging the materials from the chamber;
• a stirring paddle, which is arranged inside the reaction chamber body, wherein a rear end of the stirring paddle is connected to a motor installed on a rear side of the reaction chamber body, and the electrical control cabinet controls the operation of the motor to drive the stirring paddle to turn over the materials in the reaction chamber body;
• an air inlet, which is arranged on a front side wall of the reaction chamber main body, wherein the air inlet is connected to the inside of the reaction chamber body for adjusting an air intake time inside the reaction chamber body according to a control signal output by the electrical control cabinet;
• an air outlet, which is arranged on the rear side of the reaction chamber body, wherein one end of the air outlet is connected to the inside of the reaction chamber body, and the other end of the air outlet is dried by a color-changing silica gel and is then connected to a carbon dioxide detector;
• a discharging mechanism, comprising a leachate collection box arranged below the reaction chamber body, wherein when the leachate collection box abuts against the discharge port at the bottom of the reaction chamber body, the leachate collection box is used for receiving the leachate produced during fermentation process in the chamber;
• and when the leachate collection box is separated from the discharge port at the bottom of the reaction chamber body, and the leachate collection box is used for discharging the fermentation material in the chamber;
• a material receiving trolley, which is arranged on a lower side of the inside of the reaction chamber monomer and located below the leachate collection box, wherein the top of the material receiving trolley is of an open structure for receiving the fermentation material discharged through the discharge port at a bottom of the reaction chamber body:
• wherein the bottom of the device frame is further provided with a weight sensor at a position corresponding to each reaction chamber monomer:
• an outside of the reaction chamber monomer is further provided with a support frame, comprising:
• a side vertical plate, which is arranged on both sides of the support frame and is connected and fixed to the side wall of the reaction chamber body:
• a support base plate, which is connected to a bottom of the support frame, wherein the support base plate is further provided with a sliding rail extending from back to front, the material receiving trolley moves back and forth along the sliding rail for receiving the fermentation material that falls from the reaction chamber body:
• and after the reaction chamber monomer is installed on the device frame, the support base plate of the reaction chamber monomer is located above the weight sensor to trigger the weight sensor to collect the weight of materials in the reaction chamber monomer.
