Description

Technical Field

[0001] The invention relates to the technical field of crushing devices, in particular to an integrated RDF fuel conveying and crushing machine. Background Art

[0002] RDF fuel is a high calorific value fuel obtained through classification, crushing, dehydration, drying and other processing processes of urban domestic garbage, industrial waste, etc. Its main components include organic matter (such as paper, plastic, fiber, etc.) and some inevitable inorganic impurities. RDF fuel can not only effectively reduce the landfill and incineration of solid waste and reduce environmental pollution, but also serve as a substitute for traditional energy sources such as coal and natural gas, and play an important role in power generation, heating, industrial combustion and other fields.

[0003] Chinese patent (Announcement No.: CN117299316A), the scheme specifically includes a spiral feeder and a roller crusher, the discharging part of the roller crusher is provided with a movable interference mechanism, the interference mechanism includes a moving plate, and the two sides of the moving plate are fixedly installed with guide rods on the inner wall end faces close to the roller crusher, the guide rods are inserted into the guide grooves provided on the inner wall of the roller crusher, and can be driven by the driving mechanism to move in a circular trajectory in the guide groove. When the driving mechanism drives the moving plate meshing with it to move to the left through the rotating wheel, the paper-plastic composite waste can be changed to the left. The first contact causes the dust and combustible fibers on the paper-plastic composite waste to be shaken off. After the paper-plastic composite waste changes direction, it will contact the baffle again to further shake off the dust and combustible fibers. At this time, the dust and combustible fibers that are shaken off exist in a temporary closed space formed by the conical part, the baffle and the moving plate, providing more time for the dust suction mechanism to absorb the dust and combustible fibers.

[0004] Existing RDF fuel includes waste cloth in textile factories. When the cloth is crushed, the cloth is interwoven with fibers and has a long and flexible fiber structure. These fibers are easily entangled on the crushing roller during the crushing process to form winding circles. This phenomenon is called shaft entanglement. When the cloth is entangled in the crushing device in the above patent, the load of the crushing roller will increase, which may increase the running resistance of the equipment. At the same time, the entangled fiber cloth is difficult to be effectively crushed, and may hinder the subsequent cloth crushing process, which may reduce the crushing efficiency.

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] See also Figures 1 to 11 The present invention provides a technical solution: an integrated RDF fuel conveying and crushing machine, comprising a crushing box 1 and a crushing roller 2 with a hollow structure for crushing cloth, a plurality of high-temperature nozzles 32 for high-temperature gas circulation are arranged in the crushing box 1, and a conveying device 3 for conveying rags is arranged below the crushing roller 2, and a longitudinal cutting structure for driving the crushing roller 2 to rotate and preventing the cloth fibers from being entangled in the crushing roller 2 is arranged on the crushing box 1;

[0039] The longitudinal cutting structure includes a base plate 4 fixedly connected to the crushing box 1, a spline shaft 7 driven by a motor and freely rotating in the vertical direction is provided on the base plate 4, a spline cylinder 8 is slidably sleeved on the spline shaft 7, and the spline cylinder 8 slides through the crushing box 1, the spline shaft 7 and the crushing roller 2 are coaxially fixed, a plurality of groups of knife bodies 18 for cutting cloth fibers are provided inside the crushing roller 2, a transverse through-slit 17 is opened at the position of the knife body 18 of the crushing roller 2, and an axial cutting assembly is provided on the crushing box 1 for the plurality of groups of knife bodies 18 to rotate synchronously with the crushing roller 2 and reciprocate along the diameter section of the crushing roller 2 in an L-shaped trajectory;

[0040] An inclined steep material plate 6 is provided below the crushing roller 2, and a shaking assembly is provided on the crushing box 1 to drive the steep material plate 6 to swing back and forth in a fan-shaped trajectory in the vertical direction;

[0041] The crushing box 1 is provided with an air displacement assembly for adjusting the horizontal height of multiple groups of high-temperature nozzles 32 according to the swing amplitude of the steep material plate 6 .

[0042] like Figure 1 , Figure 2 , Figure 7 and Fig.10 As shown, when the waste cloth is crushed, the waste cloth is put into the crushing box 1. At this time, the crushing roller 2 rotating in the vertical direction applies a shearing force to the cloth, so that it is broken along the fiber direction to form smaller fragments. At the same time, when the cloth is crushed, the fibers therein may be entangled with the crushing roller 2 during the crushing process. Therefore, the shaft cutting assembly can drive multiple groups of blades 18 to reciprocate in the horizontal direction, so that the cloth fibers with shaft entanglement phenomenon are cut to reduce the shaft entanglement phenomenon.

[0043] At the same time, a transverse through-slit 17 is opened on the crushing roller 2, and a plurality of groups of blades 18 arranged in a horizontal linear array are provided inside the crushing roller 2 corresponding to the position of the transverse through-slit 17. In actual use, the plurality of groups of linearly arranged blades 18 can be arranged in a circular array on the crushing roller 2 through the plurality of groups of transverse through-slits 17. When the crushing roller 2 shears and crushes the cloth, the length of the torn fibers can be reduced, thereby avoiding or slowing down the shaft winding phenomenon, to ensure that the subsequent cloth can be crushed smoothly, thereby ensuring the cloth crushing efficiency.

[0044] It should be noted that multiple sets of blades 18 are arranged in the crushing roller 2 and rotate synchronously with the crushing roller 2. When the crushing roller 2 rotates to shear and crush the cloth, the blades 18 and the crushing roller 2 are relatively stationary, and driven by the shaft cutting assembly, the multiple sets of blades 18 reciprocate on the diameter section of the crushing roller 2, and their movement trajectory is L-shaped, wherein the blades 18 first move along the radial direction of the crushing roller 2, so that it can pass through the position of the transverse through-slit 17 to a certain height of the outer peripheral surface of the crushing roller 2, and then move horizontally relative to the crushing roller 2, so as to cut the cloth fibers wrapped thereon, so as to clean the cloth fibers that are entangled with the shaft, so that the cloth that is entangled with the shaft affects the subsequent cloth crushing process.

[0045] At the same time, the crushed cloth falls onto the steep material plate 6 below the crushing roller 2, and a plurality of groups of high-temperature nozzles 32 are arranged on the upper side of the steep material plate 6. Therefore, the crushed cloth is dried by the hot air sprayed from the high-temperature nozzles 32 to reduce the water content in the rags. At the same time, driven by the shaking component, the steep material plate 6 can swing back and forth on a fixed axis in the vertical direction, so that the rags on it can be shaken to avoid them piling up. At the same time, the shaken rags are dispersed more loosely, thereby increasing the contact area between the rags and the hot air to improve the drying efficiency, thereby significantly improving the calorific value of the RDF fuel and improving the combustion efficiency.

[0046] Furthermore, since the rags are shaken by the swinging steep material plate 6, in order to further improve the drying efficiency of the cloth, the horizontal height of the high-temperature nozzle 32 is changed by the air shifting assembly. When the steep material plate 6 swings upward, the rags thereon are lifted up. Therefore, at this time, the heights of multiple groups of high-temperature nozzles 32 can be synchronously lifted under the drive of the air shifting assembly, so that the high-temperature air sprayed from the high-temperature nozzles 32 can correspond to the height of the lifted rags, so as to improve the utilization rate of the hot air.

[0047] In one of the more preferred embodiments, the shaft cutting assembly includes a slide plate 15 that reciprocates in the horizontal direction, the slide plate 15 is fixedly connected to the spline cylinder 8, a vertical block 19 is provided on the slide plate 15, and a cutter body 18 is fixedly connected to the vertical block 19 by bolts;

[0048] An inner shaft plate 16 is fixedly connected to the inner wall of the crushing roller 2, a limit pin 20 is fixedly connected to the side of the vertical block 19 facing the slide plate 15, an oblique groove 21 for the limit pin 20 to be slidably connected is provided on the slide plate 15, and a deflected L-shaped groove 22 for the limit pin 20 to be slidably connected is also provided on the inner shaft plate 16, and the deflected L-shaped groove 22 includes an integrally formed vertical groove portion 221;

[0049] The base plate 4 is provided with a traverse assembly for driving the spline cylinder 8 to reciprocate horizontally on the spline shaft 7 .

[0050] like Figure 6-Figure 9 As shown, when the spline shaft 7 rotates in the vertical direction, it can drive the spline cylinder 8 slidably mounted thereon to rotate synchronously, wherein, when the spline cylinder 8 moves horizontally on the spline shaft 7, it can drive the slide plate 15 fixed thereon to move horizontally synchronously. In the initial state, the limit pin 20 is at the bottom of the vertical groove portion 221. Therefore, when the vertical block 19 initially moves horizontally, under the restriction of the vertical groove portion 221, the horizontal position of the vertical block 19 and the knife body 18 thereon does not change, but drives the limit pin 20 to slide on the oblique groove 21, thereby first changing the distance between the vertical block 19 and the knife body 18 and the center of the crushing roller 2, so that the knife body 18 is exposed to a certain height through the transverse through-slit 17.

[0051] At the same time, as the slide plate 15 continues to move in the horizontal direction, the limit pin 20 moves to the top position of the vertical groove portion 221. At this time, driven by the horizontal movement of the slide plate 15, the limit pin 20 can be driven to slide on the biased L-shaped groove 22, thereby making the vertical block 19 and the knife body 18 thereon move horizontally along the laying direction of the crushing roller 2, that is, along the opening direction of the transverse through seam 17, so as to cut the cloth fibers wrapped around the crushing roller 2, so as to achieve the purpose of crushing and cleaning the cloth at the same time, so as to ensure the crushing efficiency of the crushing roller 2 on the cloth.

[0052] Based on the embodiment of the axial cutting assembly, the transverse movement assembly includes a fork plate 12 which rotates on a fixed axis on a base plate 4 and swings back and forth in a horizontal direction. Two groups of ring plates 13 are fixedly sleeved on the outer ring of the spline cylinder 8. Two groups of stop pins 14 are fixedly connected to the side of the fork plate 12 facing the spline cylinder 8. The stop pins 14 are located between the two groups of ring plates 13, and the stop pins 14 are in sliding contact with the opposite surfaces of the two groups of ring plates 13.

[0053] The spline shaft 7 rotates on the base plate 4, a worm 9 is fixedly sleeved on the spline shaft 7, the worm 9 is meshingly connected with a worm wheel 10, the worm wheel 10 rotates on the base plate 4, a connecting rod 11 is provided on the worm wheel 10, and both ends of the connecting rod 11 rotate on the middle position of the worm wheel 10 and the fork plate 12 respectively.

[0054] like Figure 1-Figure 5As shown, when the spline shaft 7 is driven by the motor to continuously rotate in the vertical direction, it can drive the worm 9 fixed thereon to rotate synchronously, thereby driving the worm wheel 10 to continuously rotate on the base plate 4. At the same time, a freely swinging connecting rod 11 is provided between the base plate 4 and the fork plate 12. When the worm wheel 10 rotates, the connecting rod 11 can drive the base plate 4 to swing back and forth in the horizontal direction, thereby changing the horizontal position of the two sets of stop pins 14 at the end.

[0055] Among them, the stop pin 14 is located between the two groups of ring plates 13. When the horizontal position of the stop pin 14 changes, it can push the ring plate 13 on one side to move through its position change, and the ring plate 13 is fixed on the spline cylinder 8. Then, when the fork plate 12 swings back and forth, it can cause the spline cylinder 8 to reciprocate in the horizontal direction, thereby driving the shaft cutting assembly to operate, so as to avoid the entanglement of the cloth fibers and affect the crushing process of the cloth.

[0056] Furthermore, a support plate 5 is provided below the crushing roller 2 , the support plate 5 is tilted and fixedly connected to the inner wall of the crushing box 1 , and the support plate 5 is located above the steep material plate 6 and has an inclination angle opposite to that of the steep material plate 6 .

[0057] like Figure 1 and Figure 2 As shown, the cloth that has passed the position of the pulverizing roller 2 and has been pulverized first falls to the support plate 5, and slides along the slope of the support plate 5, and slides to the highest position of the steep material plate 6. The support plate 5 is provided to provide a guide for the pulverized cloth, and the cloth is concentrated to fall to the highest position of the steep material plate 6, so that the cloth slides from the highest point on the steep material plate 6, so as to ensure the interference path length of the rags and extend the residence time of the cloth in the drying area.

[0058] On the basis of the embodiment of the transverse movement assembly, the shaking assembly includes two groups of torsion bars 25 which rotate on the crushing box 1 with a fixed axis and swing back and forth synchronously in the vertical direction, a swing bar 29 is coaxially fixed on the torsion bar 25, and a clearance pin 30 is fixedly connected to one end of the swing bar 29 away from the torsion bar 25, and a clearance groove 31 for sliding connection of the clearance pin 30 is opened on the steep material plate 6;

[0059] The steep material plate 6 rotates on the inner wall of the crushing box 1 with a fixed axis.

[0060] like Figure 1 and Fig.10As shown, when the torsion bar 25 swings back and forth in the vertical direction, it can drive the give-way pin 30 fixed at the bottom end to swing synchronously, and the give-way pin 30 is slidably connected to the steep material plate 6 through the give-way groove 31. Therefore, when the height of the give-way pin 30 changes with the swing of the swing rod 29, the steep material plate 6 can be driven to swing on the inner wall of the crushing box 1, so that the reciprocatingly swinging steep material plate 6 can shake the cloth thereon to avoid the accumulation of rags and the occurrence of drying dead corners, and by shaking the cloth, the contact area between the rags and the hot air is increased, thereby improving the drying efficiency, and the dried cloth can slide along the slope of the steep material plate 6 to the conveying device 3 below, so that the crushed and dried waste cloth can be transferred to the next process step through the conveying device 3.

[0061] Based on the shaking assembly embodiment, the air displacement assembly includes two groups of T-shaped rods 26 arranged on the crushing box 1 and on both sides of the steep material plate 6. The crushing box 1 is provided with a rectangular slide groove for the sliding connection of the T-shaped rod 26. Multiple groups of high-temperature nozzles 32 are fixedly connected to the T-shaped rod 26, and the T-shaped rod 26 reciprocates in the vertical direction.

[0062] The crushing box 1 is provided with a side plate 23 which is freely rotatable in the vertical direction and is transmission-connected to the spline shaft 7. The side plate 23 is fixedly rotated on the inner wall of the crushing box 1. Two groups of blocking pins 24 are fixedly connected to the side plate 23. The torsion bar 25 includes an integrally formed sharp corner portion 251. Both groups of blocking pins 24 are in sliding contact with the sharp corner portion 251.

[0063] The T-shaped rod 26 is fixedly connected with a positioning rod 33, which is in sliding contact with the two groups of blocking pins 24. The T-shaped rod 26 is fixedly connected with a positioning pin 27 on the side facing the torsion bar 25. The torsion bar 25 is provided with a positioning groove 28 for the positioning pin 27 to be slidably connected.

[0064] like Figure 2 , Fig.10 and Fig.11 As shown, when the spline shaft 7 rotates in the vertical west direction, it can drive the edge disk 23 connected thereto to rotate synchronously. Two groups of blocking pins 24 are provided on the edge disk 23. When one group of blocking pins 24 conflicts with the sharp corner 251, as the edge disk 23 rotates, the group of blocking pins 24 can drive the torsion bar 25 to swing in the vertical direction by pushing the sharp corner 251.

[0065] At the same time, the positioning pin 27 fixed on the T-shaped rod 26 is slidably connected to the torsion rod 25 through the positioning groove 28. When the torsion rod 25 swings, the positioning pin 27 and the T-shaped rod 26 can be driven to move in the vertical direction through the positioning groove 28, thereby changing the height of the top set on the multiple groups of high-temperature nozzles 32. At the same time, when the torsion rod 25 swings, it drives the coaxially arranged rocker rod 29 to swing synchronously, so as to drive the shaking assembly to move, thereby changing the horizontal inclination angle of the steep material plate 6.

[0066] Among them, as the edge plate 23 continues to rotate, the blocking pin 24 disengages from the sharp corner 251, and the crushing box 1 is provided with two sets of torsion springs that drive the steep material plate 6 and the torsion bar 25 to return to the initial deflection angle. The torsion spring is an existing device and a technical means well known to those skilled in the art, so it is not shown in the figure. Therefore, under the action of the two sets of torsion springs, the T-bar 26 can be restored to the initial height, and the steep material plate 6 is restored to the initial deflection angle.

[0067] Furthermore, when the blocking pin 24 contacts the isotropic rod 33, as the edge plate 23 rotates, the T-shaped rod 26 can be driven to move downward a certain distance, and then the positioning pin 27 provided on the T-shaped rod 26 drives the torsion rod 25 to deflect in the opposite direction, and then the horizontal inclination angle of the steep material plate 6 is changed through the rocker rod 29, so that the steep material plate 6 can have a larger slope, so that the cloth thereon can slide more smoothly from the steep material plate 6 to the conveying device 3 below, so as to ensure that the rags can be driven by the conveying device 3 to be conveyed downward to the next process.

[0068] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
