Description
Technical Field
[0001] This invention relates to the field of waste-derived fuel technology, specifically to a dual-mode RDF forming device. Background Technology
[0002] RDF, or Refuse-Derived Fuel, is a type of fuel produced by crushing, sorting, drying, and adding chemicals to combustible waste before it is compressed into fuel using an RDF molding machine. Currently, RDF molding machines primarily process plant stalks, cow and sheep manure, and kitchen waste. However, they remain difficult to process common household waste such as paper-plastic composites and sludge (e.g., plastic packaging boxes with paper labels or dyeing mud).
[0003] Ring die RDF forming equipment typically features a transverse pressure roller rotating around a pivot inside a stationary ring die. During rotation, the transverse pressure roller squeezes the inner wall of the ring die, forcing the raw material into the forming holes to obtain RDF fuel rods of a specific shape. However, in actual processing, fuel is poured in from above the ring die. Most of the raw material is thrown to the inner wall of the ring die and squeezed into the forming holes by the centrifugal force of the rotating transverse pressure roller. A small portion of the raw material that is not squeezed into the forming holes gradually accumulates on the bottom wall of the ring die, making it difficult to be lifted and squeezed into the forming holes again, especially... The sludge is adhesive and, after being squeezed, it adheres firmly to the bottom wall of the ring die. The plastic component of paper-plastic composite waste is relatively hard, and excessive plastic material accumulating on the bottom wall will continuously rub against the transverse pressure roller, causing wear on the transverse pressure roller. Furthermore, in existing ring die RDF forming equipment, the transverse pressure roller itself does not have the power to rotate; it is only driven by the rotating shaft to move along the inner wall of the ring die. As a result, there is a lot of sliding movement between the outer wall of the transverse pressure roller and the inner wall of the ring die during the production process, leading to greater wear on both and thus affecting the service life of the equipment.
[0004] To address the issues of raw material accumulation at the bottom of the ring die in ring die RDF forming equipment, excessive sliding wear between the outer wall of the pressure roller and the inner wall of the ring die, and the quality problems of RDF fuel rods, improvements are needed to the existing ring die RDF forming equipment. Summary of the Invention
[0005] The problem this invention aims to solve is to provide an RDF molding device that can extrude paper-plastic composite raw materials and sludge-like raw materials accumulated at the bottom of a ring die, and whose pressure rollers can rotate to reduce wear, resulting in higher quality RDF fuel rods.

Detailed Implementation
[0025] The embodiments of the present invention will be further described below with reference to the accompanying drawings.
[0026] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4A dual-mold RDF forming device includes a ring mold 1, a rotating shaft assembly 2 disposed in the ring mold 1, and a plurality of transverse pressure rollers 3 disposed on the side of the rotating shaft assembly 2; the ring mold 1 has a plurality of transverse forming holes 11 along its side wall, and a raw material collecting mold 4 is disposed at the bottom of the ring mold 1; the raw material collecting mold 4 includes a collecting groove 41, and the bottom of the collecting groove 41 has a longitudinal forming hole 42; a plurality of longitudinal pressure rollers 5 are movably connected to the side of the rotating shaft assembly 2; when the rotating shaft assembly 2 rotates, it drives the transverse pressure rollers 3 to revolve along the inner side wall of the ring mold 1, so that the raw material is pressed into the transverse forming holes 11, and the longitudinal pressure rollers 5 are driven synchronously. The material is pressed into the longitudinal forming hole 42 by revolving along the collection groove 41. The bottom of the material collection mold 4 is provided with a conical toothed disc 43. The longitudinal pressure roller 5 is provided with a proximal conical toothed part 51 on the side near the rotating shaft assembly 2. The conical toothed disc 43 meshes with the proximal conical toothed part 51 so that the longitudinal pressure roller 5 rotates along the collection groove 41 while rotating on its own axis. The side of the longitudinal pressure roller 5 away from the rotating shaft assembly 2 is provided with a distal conical toothed part 52. The lower end face of the transverse pressure roller 3 is provided with a driving conical toothed part 31. The distal conical toothed part 52 meshes with the driving conical toothed part 31 so that the transverse pressure roller 3 rotates on its own axis while revolving along the inner side wall of the ring mold 1.
[0027] Mixing and pressing sludge-based raw materials with paper-plastic composite raw materials can overcome the defects of paper-plastic composite raw materials being too dry, loose, and difficult to extrude after crushing. At the same time, it can process sludge-based raw materials that are difficult to recycle. Moreover, the processed sludge paper-plastic composite RDF fuel has the advantages of high calorific value and stable calorific value, and can be widely used in cement plants and power plants for energy supply.
[0028] During use, raw materials are added from above the ring die 1. Specifically, the raw materials are mainly composed of paper-plastic composite waste and sludge. Under the revolution of the transverse pressure roller 3, the raw materials are thrown towards the inner wall of the ring die 1 and extruded from the transverse forming hole 11 to form RDF fuel rods. During the addition of raw materials and the operation of the transverse pressure roller 3, any missed raw materials will enter the raw material collection mold 4 with longitudinal forming holes 42 at the bottom of the ring die 1 and eventually accumulate in the collection trough 41. The collection trough 41 is equipped with several longitudinal pressure rollers 5 driven by the rotating shaft assembly 2, which will extrude the raw materials accumulated in the collection trough 41 after forming.
[0029] During the movement of the longitudinal pressure roller 5, since the bottom of the raw material collecting mold 4 is provided with a bevel toothed disc 43, and the longitudinal pressure roller 5 is provided with a proximal bevel toothed part 51 on the side near the rotating shaft assembly 2, when the longitudinal pressure roller 5 revolves along the collecting groove 41, the proximal bevel toothed part 51 and the bevel toothed disc 43 cooperate to generate rotation, and the sliding motion between the longitudinal pressure roller 5 and the bottom of the collecting groove 41 is changed to rolling motion, thereby reducing the wear between the longitudinal pressure roller 5 and the raw material collecting mold 4.
[0030] Since the longitudinal pressure roller 5 rotates during its movement, and the longitudinal pressure roller 5 has a distal bevel tooth 52 on the side away from the rotating shaft assembly 2, and the lower end face of the transverse pressure roller 3 has a driving bevel tooth 31, the distal bevel tooth and the driving bevel tooth cooperate with each other, so that the rotation of the longitudinal pressure roller 5 can drive the transverse pressure roller 3 to rotate, changing the sliding motion of the transverse pressure roller 3 along the inner wall of the ring die 1 into rolling motion, thereby reducing the wear between the transverse pressure roller 3 and the inner wall of the ring die 1.
[0031] Please continue reading. Figure 2 , Figure 3 , Figure 4 The rotating shaft assembly 2 includes a turntable 21 disposed above the bevel gear disk 43; the side wall of the turntable 21 is provided with a plurality of connecting shafts 22; the proximal bevel gear 51 is provided with a connecting part 53 on the side near the rotating shaft assembly 2; the connecting part 53 is rotatably connected to the connecting shaft 22.
[0032] In use, the turntable 21 drives several longitudinal pressure rollers 5 to revolve along the collection groove 41. In order for the longitudinal pressure rollers 5 to rotate freely during the revolution, the connecting part 53 is rotatably connected to the connecting shaft 22.
[0033] Please refer to further information. Figure 2 , Figure 3 , Figure 4 The rotating shaft assembly 2 also includes a mounting frame 23 fixedly connected above the turntable 21; the mounting frame 23 extends several cantilever arms 24 toward the inner wall of the ring mold 1; the number of cantilever arms 24 is the same as the number of connecting shafts 22; the axis of the cantilever arms 24 is the same as the axis of the connecting shafts 22; a roller connecting part 25 is provided at one end of the cantilever arm 24 near the inner wall of the ring mold 1; the transverse pressure roller 3 is rotatably connected to the lower part of the cantilever arm 24 through the roller connecting part 25; a reinforcing rib 26 is provided between the mounting frame 23 and the cantilever arm 24.
[0034] In actual use, the mounting bracket 23 and the cantilever 24 are set so that the transverse pressure roller 3 can be raised above the longitudinal pressure roller 5. The central axis of the cantilever 24 is consistent with the central axis of the connecting shaft 22, so that the relative position of the longitudinal pressure roller 5 of each pair of transverse pressure rollers 3 is always kept constant, which makes it easy for the longitudinal pressure roller 5 to drive the corresponding transverse pressure roller 3 to rotate when it rotates.
[0035] Please refer to further information. Figure 2 , Figure 3 In order to collect the raw material that has not entered the transverse forming hole 11 and to ensure that the raw material can accurately reach the position that is easy for the longitudinal pressure roller 5 to crush, the inner side of the collection groove 41 near the ring die 1 is inclined so as to guide the raw material that has not been squeezed into the transverse forming hole 11 into the collection groove 41.
[0036] Please continue reading. Figure 2 , Figure 3 , Figure 5 , Figure 7 The raw material collection mold 4 is provided with a conveying assembly 6 below it. The conveying assembly 6 includes a transverse hole discharge conveying section 61 and a transverse hole discharge guide section 64. The transverse hole discharge guide section 64 is used to smoothly introduce the RDF fuel rods extruded from the transverse forming hole 11 into the transverse hole discharge conveying section 61. The inner side of the transverse hole discharge conveying section 61 is provided with a longitudinal hole discharge conveying section 62 to smoothly guide the RDF fuel rods extruded from the longitudinal forming hole 42 into the transverse hole discharge conveying section 61. The transverse hole discharge conveying section 61 is provided with a cutting blade 65 that rotates along the outer wall of the ring die 1 to cut the RDF fuel rods extruded from the transverse forming hole 11 and make them fall into the transverse hole discharge guide section 64.
[0037] In actual use, when the RDF fuel rods are gradually extruded from the transverse forming hole 11, the transverse hole discharge guide 64 will first act as a guide. Specifically, the transverse hole discharge guide 64 includes a planar guide layer and an inclined guide layer, so that the RDF fuel rods first fall into the relatively lower planar guide layer, and then roll down from the inclined guide layer to the transverse hole discharge conveyor 61. This prevents the RDF fuel rods from falling directly from an excessively high position to the transverse hole discharge conveyor 61 and breaking or becoming loose, thereby improving the quality of the RDF fuel rods extruded from the transverse forming hole 11. The transverse hole discharge guide 64 is connected to the outer shell structure of the present invention through a connecting rod and does not contact the transverse hole discharge conveyor 61 or the longitudinal hole discharge conveyor 62. Therefore, the rotation of the transverse hole discharge conveyor 61 and the longitudinal hole discharge conveyor 62 will not interfere with the transverse hole discharge guide 64.
[0038] In order to cut off the RDF fuel rods extruded from the transverse forming hole 11 in a timely manner, the transverse hole discharge conveying part 61 is provided with a cutting tool 65 that rotates along the outer wall of the ring die 1. The cutting tool 65 is located in the gap between the outer wall of the ring die 1 and the transverse hole discharge guide part 64, so the rotation of the cutting tool 65 will not interfere with the transverse hole discharge guide part 64.
[0039] The amount of raw material accumulated in the raw material collection die 4 is less than that extruded from the ring die 1. Therefore, the amount of RDF fuel rods extruded from the longitudinal forming hole 42 is also less. The RDF fuel rods extruded from the longitudinal forming hole 42 are smoothly guided by the longitudinal forming hole discharge conveyor 62, which can prevent the RDF fuel rods from falling directly from an excessively high position and breaking or becoming loose, thereby improving the quality of the RDF fuel rods extruded from the longitudinal forming hole 42.
[0040] like Figure 7As shown, since the angle between the RDF fuel rod extruded from the transverse forming hole 11 and the tangent of the cutting tool 65 is an acute angle, when the guide block 512 passes by, the guide block 512 will squeeze the cut-off end of the RDF fuel rod and adjust the direction of this end to be flat with the other end so that it can roll off from the transverse hole discharge guide part 64, thereby avoiding the RDF fuel rod from breaking, shattering, or loosening due to gravity falling.
[0041] Please refer to further information. Figure 2 , Figure 3 In use, in order to convey the pressed RDF fuel rods, the present invention is provided with a conveying assembly 6, wherein the discharge end of the transverse forming hole 11 is set as a transverse hole discharge conveying part 61, and the discharge end of the longitudinal forming hole 42 is set as a longitudinal hole discharge conveying part 62. When the RDF fuel rod is extruded from the longitudinal forming hole 42, it will slide down to the transverse hole discharge conveying part 61 and be sent out together with the RDF fuel rod extruded from the transverse forming hole 11.
[0042] Please see Figure 5 , Figure 6 The conveying assembly 6 is externally provided with a housing 7; the housing 7 includes a cover 71 disposed on the top and a feed hood 73 disposed on the cover 71 to ensure that the raw materials are processed in this invention; the housing 7 also includes a discharge port 72 disposed on one side; a finished product conveyor belt 8 is disposed on one side of the discharge port; a baffle 721 is disposed on one side of the discharge port 72 for guiding the RDF fuel rods conveyed by the transverse hole discharge conveying section 61 into the conveyor belt 8; the feed hood 73 communicates with the ring die 1; the conveying assembly 6 also includes a conveying motor 63; The conveying motor 63 is fixedly connected above the cover 71 and is connected to the transverse hole discharge conveying part 61 by gears to provide rotational power to the transverse hole discharge conveying part 61. The invention also includes a machine base 9, on one side of the upper end face of the machine base 9 is a power motor 91, and on the other side of the upper end face is a support part 92; the raw material collection mold 4 is set above the support part 92; the rotating shaft assembly 2 is movably connected in the support part 92; the power motor 91 and the rotating shaft assembly 2 are connected by a belt and a gear set to provide rotational power to the rotating shaft assembly 2.
