Referring to fig. 1 and 2, a desorption regeneration device for waste silicone oil glue comprises a furnace body 1, wherein a feed inlet 2 and an exhaust outlet 3 are arranged at the top of the furnace body 1, a discharge outlet 4 is arranged at the bottom of the furnace body 1, a plurality of layers of baffle plates 5 are arranged in the furnace body 1, an oxygen pipe 6 connected with a pressure-stabilizing oxygen source is arranged on the side wall of the bottom of the furnace body 1, the end part of the oxygen pipe 6 extends to the position below the baffle plate 5 at the bottommost layer in the furnace body 1, the end part of the oxygen pipe 6 is vertically upward, an oxygen hole 7 is formed in the side wall of the end part of the oxygen pipe 6, an adjusting ring 8 is movably sleeved on the side wall of the end part of the oxygen pipe 6 and used for partially plugging the oxygen hole 7, an induction plate 10 is connected to the top of the adjusting ring 8 through a linkage rod 9, the top surface of the induction plate 10 is an inclined surface, and the bottom surface of the induction plate 10 is supported on the top surface of the end part of the oxygen pipe 6 through an elastic piece 11;

In the invention, the top surface of the sensing plate 10 is used for receiving the dropped calcined material, if the calcined material is an oil-containing material, it is indicated that oil is not calcined cleanly, because of the increased weight and viscosity of the material, the impact force of the material on the sensing plate 10 is increased on one hand, and the retention and accumulation phenomenon may occur on the other hand, so that the pressure of the material on the sensing plate 10 is increased, the sensing plate 10 is pressed down, the adjusting ring 8 is driven to be pressed down by the linkage rod 9, the elastic piece 11 is contracted, at the moment, the area of the non-plugged part of the oxygen hole 7 is increased, the oxygen supply amount is increased, the oil is ensured to be calcined cleanly, when the calcined material does not contain oil, the weight is reduced and the calcined material is not viscous, the calcined oil falls onto the top surface of the sensing plate 10, the sensing plate 10 is kept at a certain height, the area of the non-plugged part of the oxygen hole 7 is stabilized at a certain value, and oxygen is continuously supplied. Therefore, the oxygen supply amount is basically positively correlated with the initial oil content of the waste silicone oil rubber, so that the oil is fully calcined clean and no oxygen waste is caused.
Preferably, the top surface of the sensing plate 10 is conical or pyramid shaped to help disperse the material and slide down.
In the invention, the baffle plate 5 is divided into an A plate and a B plate, wherein the A plate is provided with a circulation port 12 at the outer ring of the circumference, the B plate is provided with a circulation port 12 at the center of the circumference, the A plate and the B plate are distributed in a staggered way, and the baffle plate 5 has the function of enabling materials to be conveyed along an S-shaped route and increasing the treatment time. Correspondingly, a driving piece 13 (such as a motor) is arranged at the top of the furnace body 1, a stirring shaft 14 is arranged at the output end of the driving piece 13, stirring pieces 15 with the same number as that of the baffle plates 5 are arranged on the stirring shaft 14, the stirring pieces 15 are positioned at the upper ends of the baffle plates 5 in one-to-one correspondence, the stirring pieces 15 positioned at the upper ends of the A plates are arranged to rotate to generate centrifugal thrust, materials are pushed to the circulation port 12 of the circumference outer ring, the stirring pieces 15 positioned at the upper ends of the B plates are arranged to rotate to generate centripetal thrust, and the materials are pushed to the circulation port 12 of the circumference center.
In the invention, as shown in fig. 3, a natural gas supply mechanism is arranged on the side wall of the bottom of a furnace body 1, the natural gas supply mechanism comprises an outer cylinder 16 and an inner cylinder 17 which are mutually sleeved, an interlayer cavity 18 is formed between the outer cylinder 16 and the inner cylinder 17, the interlayer cavity 18 is communicated with the furnace body 1, a blocking net 19 is arranged at the communication position, the blocking net 19 is used for avoiding leakage of materials, the inner cylinder 17 is connected with a stabilized natural gas source, the side wall of the inner cylinder 17 is provided with a natural gas hole 20, a piston disc 21 is arranged in the inner cylinder 17, a thermal expansion cold shrinkage column 22 is transversely arranged in the furnace body 1, a movable column 23 is penetrated through the side wall of the furnace body 1, one end of the thermal expansion cold shrinkage column 22 is fixed on the inner wall of the furnace body 1, and the other end of the thermal expansion cold shrinkage column 23 is movably stretched into the inner cylinder 17 and connected with the piston disc 21;
in the treatment process, when the calcining temperature in the furnace body 1 rises, the thermal expansion and contraction column 22 stretches and drives the piston disc 21 to move in the inner cylinder 17 so as to reduce the flow area of the natural gas holes 20, reduce the supply amount of the natural gas, and at most completely close the supply, thereby avoiding the continuous rising of the temperature and saving the natural gas; when the calcining temperature in the furnace body 1 is reduced, the expansion and contraction column 22 shortens and drives the piston disc 21 to move in the inner cylinder 17, so that the flow area of the natural gas holes 20 is increased, and the supply amount of the natural gas is increased, and the natural gas can be fully opened at most, thereby increasing the temperature. Finally, the temperature of a calcining zone in the furnace body 1 is maintained at a stable value, and when the self-combustion heat supply is insufficient, the carbonization temperature is insufficient, and natural gas is automatically supplied at the moment to supplement the heat required by material calcination; when the retorting temperature is sufficient, the natural gas supply is reduced or stopped. Throughout the conditioning process, the natural gas supply is temperature dependent.
In the present invention, the expansion and contraction column 22 is made of a metal material with a high expansion coefficient, such as copper, however, since the inner diameter of the furnace body 1 is limited, the degree of expansion and contraction of the conventional metal material is still smaller, so that the opening adjustment range for the natural gas hole 20 is smaller. Therefore, the structure of the heat expansion and cold contraction column 22 is optimized, and as shown in fig. 4, the heat expansion and cold contraction column 22 comprises connectors 221 at two ends and a plurality of sub-columns 222 between the two connectors 221, one end of each sub-column 222 is formed with a conical projection 223, the other end is formed with a conical groove 224 matched with the conical projection 223, and adjacent sub-columns 222 are movably spliced through the conical projections 223 and the conical grooves 224, so that all sub-columns 222 are sequentially connected in series along a straight line; an elastic piece 24 is arranged in the inner cylinder 17, and the elastic piece 24 is connected with the piston disc 21 and is used for generating elastic extrusion force on the piston disc 21, the movable column 23 and the expansion and contraction column 22;
when the calcining temperature in the furnace body 1 rises, each sub-column 222 of the heat expansion and cold contraction column 22 expands axially and radially, wherein the expansion in the axial direction directly leads the heat expansion and cold contraction column 22 to extend, the expansion in the radial direction leads the conical convex block 223 to be widened, the conical groove 224 to be narrowed, and the distance between the adjacent sub-columns 222 is increased, thereby indirectly leading the heat expansion and cold contraction column 22 to extend, and the elastic piece 24 is compressed after the heat expansion and cold contraction column 22 extends; when the calcining temperature in the furnace body 1 is reduced, each sub-column 222 of the heat expansion and cold contraction column 22 is contracted in the axial direction and the radial direction, wherein the axial contraction directly shortens the heat expansion and cold contraction column 22, the radial contraction narrows the conical protruding block 223 and the conical groove 224, and the distance between the adjacent sub-columns 222 is reduced under the extrusion of the elastic piece 24, so that the heat expansion and cold contraction column 22 is shortened indirectly. Thus, the degree of thermal expansion and contraction of the thermal expansion and contraction column 22 can be improved, and the adjustment step of the natural gas hole 20 can be improved.
The foregoing examples illustrate only a few embodiments of the invention and are described in detail herein without thereby limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention.
