Description

Technical Field

[0001] This invention relates to the field of waste recycling technology, specifically to a solid waste recycling device for the production of plastic-coated steel prefabricated direct-buried insulated pipes. Background Technology

[0002] The patent application with publication number CN221161172U includes a support platform with a support frame at the bottom. The support platform has parallel insulation layer recycling troughs and steel pipe recycling troughs. One end of the insulation layer recycling trough is equipped with a conveying support mechanism, the middle of the insulation layer recycling trough is equipped with a peeling mechanism, and the other end of the insulation layer recycling trough is equipped with a steel pipe support mechanism that can move horizontally back and forth between the insulation layer recycling trough and the steel pipe recycling trough. It also includes a pipe unloading mechanism set on the steel pipe support mechanism. This utility model facilitates cutting open the insulation layer covering the steel pipe and peeling it off the steel pipe, and sorting and recycling the insulation layer and steel pipe, improving waste recycling efficiency, reducing the workload of operators, and further improving safety performance.

[0003] In the aforementioned patent, during the recycling and reuse of waste plastic-coated steel insulation pipes, the surface of the insulation pipes often adheres to a large number of impurities. This mainly stems from two aspects: firstly, during the pre-burial construction, the pipes are dragged on the ground, making it easy for stones and fragments to embed into their surface; secondly, when buried insulation pipes are excavated for replacement or repair, their outer surface is usually firmly adhered to a layer of mud formed by a mixture of rainwater and soil, which often contains and mixes stones, fragments, and other impurities. These complex pollutants have strong adhesion and are difficult to clean, making traditional recycling methods insufficient for pre-treatment. Direct crushing faces numerous problems such as high blade wear, high energy consumption, poor finished product purity, and easy material adhesion and blockage. Summary of the Invention

[0015] Compared with the prior art, the technical solution of the present invention has the following advantages: (1) The clamping mechanism of the present invention, while achieving stable fixation, can also efficiently remove dirt, sand, debris and other impurities from the surface of the plastic-coated steel insulation pipe waste through the combination of heating and rotation cleaning functions. After the worker puts the insulation pipe waste on the connecting rod, the second motor can drive the drive rod to move axially. Through the cooperation of the inclined surfaces of the extrusion wedge and the sliding wedge on it, the three sets of arc plates are forced to expand outward synchronously in the radial direction, thereby achieving uniform and firm support and fixation from the inside of the waste. At the same time as it expands, the dirt or loose impurities attached to the outer surface of the insulation pipe will fall off. In addition, this clamping method is suitable for different pipe diameters and the force is uniform, avoiding local deformation. After clamping, the outer wall of the waste automatically fits tightly with the three sets of arc heating plates preset in the fixing platform mechanism. After the heating plate is activated, it can heat and soften the waste plastic layer in a surrounding manner. This not only reduces the toughness of the material and reduces the resistance for subsequent cutting, but also keeps the waste tube wall in a slightly taut state under the continuous radial expansion force provided by the arc plate. Combined with the slight vibration and friction generated by the slow rotation of the whole driven by the first motor, it can effectively remove loose sand, gravel and other solid impurities that are attached to the plastic surface due to production and burial. This significantly reduces the load on the subsequent cleaning process and improves the overall cleanliness and recycling quality of the waste. (2) This invention achieves efficient cleaning and rapid drying of waste materials after cutting through the cooperation of the cleaning mechanism and the drying component. The waste materials fall into the sliding frame, and cleaning water is injected into the sliding frame through the water inlet pipe. The U-shaped grooves around the inner wall and the water pump make the water flow to rinse and wash the surface of the waste materials, powerfully removing stubborn attachments such as oil and dust. The wastewater is discharged through the drain pipe. After cleaning, the operator can easily push the entire sliding frame along the guide rail to the drying station, and the waste materials will slide onto the movable plate. During the drying stage, the warm air blowers on both sides of the shell are started. Hot air is directed and concentrated in the sealed space above the movable plate through the connecting pipe, and the waste materials are dried evenly and efficiently in a surrounding hot air drying manner, which can quickly remove the residual moisture on the surface. This process effectively prevents the wet materials from sticking to the blades or clumping during the subsequent crushing process, ensuring the smoothness of the crushing operation and the uniformity of the particles, which is efficient and reduces the pollution and loss of material transfer.

The connection point between the connecting pipe 47 and the housing 11 is located above the movable plate 43.

[0030] The working principle of this invention is as follows: Workers first cut the entire plastic-coated steel insulation pipe waste into sections, facilitating subsequent crushing. The workers then place the waste plastic-coated steel insulation pipe onto the connecting rod 242 of the clamping mechanism 2. The second motor 259 is started, driving the threaded rod 258 to rotate, causing the driving rod 25 to move axially within the mounting cavity 243. The pressing inclined block 251 on the driving rod 25 moves accordingly, pressing the inclined surface of the sliding inclined block 261. Under the constraint of the limiting groove 244, the sliding inclined block 261 drives the connected horizontal plate 262 and three sets of arc-shaped plates 26 to expand radially outward synchronously, thereby opening up from the inside and firmly clamping the insulation pipe waste. After clamping and fixing, the outer wall of the insulation pipe waste is tightly fitted with the three sets of arc-shaped heating plates 121 preset inside the arc-shaped shell 12 of the fixing platform mechanism 1. The arc-shaped heating plate 121 is activated, providing a surrounding heating effect on the waste material, softening its plastic layer and reducing subsequent cutting resistance. Simultaneously, the radial expansion force of the arc-shaped plate 26 keeps the waste pipe wall taut, causing loosely attached sand, gravel, and other impurities to detach under vibration and gravity. Subsequently, the first motor 22 is activated, slowly rotating the entire clamping mechanism 2 and the insulated waste pipe fitted onto its outer surface. This causes relative friction between the outer wall and the arc-shaped heating plate 121, further dislodging any remaining loose impurities or dirt. The detached impurities or dirt pass through the space below and eventually fall into the bottom frame 311 of the cleaning mechanism 3. After preheating and initial impurity removal are completed, the drive rod 25 continues to move axially under the drive of the second motor 259. At this time, the end of the extrusion wedge 251 begins to contact and push the irregular sliding ring 253. The irregular sliding ring 253 slides axially, and through the linkage mechanism composed of the first hinge seat 256, the hinge rod 273, and the second hinge seat 272, the three sets of fixed sliding plates 271 slide radially outward along their respective limiting grooves 245, driving the three sets of blades 27 fixed thereon to extend out from the gaps between the three sets of arc-shaped plates 26, radially cutting and decomposing the heated and softened insulation pipe waste. After cutting, the second motor 259 reverses, the drive rod 25 retracts, the blades 27 retract under the linkage of the mechanism, the arc-shaped plates 26 contract, releasing the cut waste, which falls into the cleaning mechanism 3 below under the action of gravity.

[0031] The cut waste material falls into the sliding frame 321 of the sliding frame assembly 32. Cleaning water is injected into the sliding frame 321 through the water inlet pipe 322, and the water pump installed in the U-shaped channel 323 is started. The water pump draws water from one port of the U-shaped channel 323 into the sliding frame 321 and sprays the water out from the other port, forming a flowing rinsing water stream that effectively washes the surface of the waste material, removing oil, dust, and other adhering substances. After cleaning, the water pump stops working. At this time, the impurities are located in the bottom frame 311, and the wastewater is discharged through the drain pipe 315. The cleaned waste material remains in the sliding frame 321 above the filter plate 312.

[0032] After the cleaning process is completed, the worker pushes the sliding frame 321, causing it to slide along the second trapezoidal limiting rod 113 towards the drying assembly 4. The waste material inside the sliding frame 321 moves accordingly and slides down from its end opening onto the movable plate 43. At this time, the warm air blowers 46 on both sides of the housing 11 are activated, and hot air is blown into the housing 11 through the connecting pipe 47 and concentrated in the space above the movable plate 43 to evenly dry the waste material, remove surface moisture, and prevent sticking during subsequent crushing.

[0033] After drying, the electric push rod 45 is activated, pulling the fixed plate 44 and causing the movable plate 43 to retract into the slot 42 of the fixed plate 41. The dried waste material on the movable plate 43 loses its support and falls into the crushing device 5 located directly below it. The crushing device 5 is activated, breaking the lumpy waste material into granules for subsequent recycling.

The scope of protection of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to the present invention within its spirit and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of the present invention.
