Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to an auxiliary material breaking-up device for burning alternative fuel briquette. Background Art

[0002] The utilization of heat energy from garbage incineration is an environmentally friendly treatment method. During combustion, it is necessary to add combustion-supporting auxiliary materials, which are generally waste textile rags. The waste textile rags are transported by compression and bundled into rag piles. Before burning, the rag piles need to be broken up so that they can be evenly laid with the garbage to improve combustion efficiency. The existing rag piles are broken up by arranging multiple steel bars or knives on the scattering roller. During the scattering, the waste textile rags are easily entangled on the scattering roller, affecting the scattering effect of the scattering roller. Once the waste textile rags are entangled, they will become tighter and tighter. Cleaning the waste textile rags usually requires the use of blades, angle grinders, etc., which is a time-consuming and labor-intensive project that seriously affects work efficiency. At the same time, during the scattering process of the rag pile, if the scattering roller becomes stuck, the staff needs to control the belt conveyor to reverse, move the rag pile back a certain distance, and then put it on the scattering roller again for scattering. The degree of automation is not high. Utility Model Content

Therefore, it should not be understood as limiting the present invention. In addition, if the terms "first", "second", etc. appear in the description of the present invention, they are only used to distinguish the description and should not be understood as indicating or implying relative importance.

[0019] In the description of the embodiments of the present invention, it should be noted that, unless otherwise specified or limited, the terms "disposed" and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0020] As shown in the accompanying drawings, the utility model includes a crushing and scattering machine and a belt conveyor 2. The crushing and scattering machine includes a frame 3 and a pair of scattering rollers 4. The pair of scattering rollers 4 are staggered and installed on the frame 3. The frame 3 is provided with a driving motor 5 that drives the pair of scattering rollers 4 to rotate.

[0021] There is a group of first scattering plates 6 in the circular array in the middle of the roller surface of the scattering roller 4, and two second scattering plates 7 are provided on the scattering roller 4 between two adjacent first scattering plates 6. The two second scattering plates 7 are symmetrically located at both ends of the roller surface of the scattering roller 4, and the belt conveyor 2 is located below the scattering roller 4 near the bottom.

[0022] The first scattering plate 6 and the second scattering plate 7 are staggered on the roller surface of the scattering roller 4. The first scattering plate 6 and the second scattering plate 7 scatter the waste rags in the process of following the rotation. The scattering roller 4 is 1500mm long and 800mm in diameter. The first scattering plate 6 is 900mm long and the second scattering plate 7 is 550mm long. The height of the first scattering plate 6 and the second scattering plate 7 are both 200mm. The first scattering plate 6 and the second scattering plate 7 are plate-shaped structures, which are not easy to entangle the waste cloth strips when scattering. The upper and lower scattering rollers 4 are staggered. The scattering roller 4 at the top is staggered 400mm backward relative to the scattering roller 4 at the bottom. When scattering, the scattering roller 4 at the bottom first contacts the waste rag bag and scatters the lower part of the waste rag bag, so that the entire pile of rags can be tilted toward the scattering roller 4 and pressed against the scattering roller 4, which is convenient for rapid scattering.

[0023] Preferably, the rotation directions of the pair of scattering rollers 4 are opposite, and there are two drive motors 5, which respectively control the rotation of the corresponding scattering rollers 4.

[0024] In this case, the upper scattering roller 4 rotates clockwise, and the lower scattering roller 4 rotates counterclockwise, which effectively prevents waste fabric from accumulating between the two scattering rollers 4.

[0025] The two breaking up rollers 4 are respectively controlled by independent motors, which can effectively prevent the jamming phenomenon.

[0026] Preferably, the first scattering plate 6 and the second scattering plate 7 are both hollow structures, and both ends of the first scattering plate 6 and the second scattering plate 7 are provided with arc chamfers.

[0027] The hollow structure can prevent the first scattering plate 6 or the second scattering plate 7 from bending as a whole during use. During actual installation, a reinforcing rib is provided in the hollow structure to ensure its strength, and the arc chamfer can further prevent the problem of cloth strips being entangled.

[0028] Furthermore, an infrared sensor 10 electrically connected to the frequency converter of the belt conveyor 2 is provided on the frame 3 located in front of the pair of scattering rollers 4 .

[0029] After the machine is turned on, when the infrared sensor 10 does not detect the pile of rags, it means that the pair of scattering rollers 4 are in an idling state. At this time, the infrared sensor 10 gives a 50HZ signal to the frequency converter of the belt conveyor 2. At this time, the belt conveyor 2 runs at full speed until the pile of rags is located at the sensing point of the infrared sensor 10. The infrared sensor 10 again gives the frequency converter of the belt conveyor 2 a normal rated HZ operation to ensure uninterrupted material flow.

[0030] Furthermore, the belt conveyor 2 is provided with a speed sensor 11 for monitoring the speed of the conveying belt. The speed sensor 11 is electrically connected to the frequency converter of the belt conveyor 2 .

[0031] If the rags are packed too tightly and cannot be continuously broken up at the pair of breaking rollers 4, that is, the belt conveyor 2 cannot continue to convey forward, the speed sensor 11 detects that the belt conveyor 2 is stuck and has no speed signal, the belt conveyor 2 stops, and the inverter is given a reverse signal for 15 seconds. After that, the belt conveyor 2 stops and then operates normally again.

[0032] That is, the pile of rags is moved back a distance, and then enters the scattering roller 4 to be scattered again, and the stuck state is released to ensure normal and continuous scattering.

[0033] Furthermore, a group of anti-slip bars 12 are arranged on the conveying belt of the belt conveyor 2 along its conveying direction.

[0034] The anti-slip bar 12 is a ∠30 angle iron. Preferably, the spacing between two adjacent anti-slip bars 12 is 800-1000 mm.

[0035] The anti-slip bar 12 can prevent the pile of rags from sliding backward on the belt conveyor 2, and maintains a forward conveying force on the pile of rags.
