[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0028] See also Figures 1 to 3The utility model is a bag breaking and separation device, comprising: a linear conveying mechanism 100, used to carry and convey alternative fuel bags; a shell 200, wherein the interior of the shell 200 is provided with a accommodating chamber 210, the side of the shell 200 is provided with a feed port 220 for docking with one end of the linear conveying mechanism 100, and the lower part of the shell 200 is provided with a discharge port 230 connected to the accommodating chamber 210; a knife shaft device 300, rotatably arranged in the accommodating chamber 210, and the knife shaft device 300 is provided with at least two crushing knife groups distributed around its axial circumference 400, the crushing knife group 400 includes a plurality of knife units 410 that are roughly arranged in a row along the axial direction of the knife shaft device 300; wherein, the housing 200 is provided with a loading platform 240 at the lower edge of the feed port 220 that is flush with the height of the linear conveying mechanism 100, and the loading platform 240 and the linear conveying mechanism 100 jointly support the alternative fuel package, and when the knife shaft device 300 rotates, the crushing knife group 400 cuts through the plastic film wrapped around the outside of the alternative fuel package and impacts and breaks up the alternative fuel package.
[0029] The above-mentioned package breaking and separation equipment uses the linear conveying mechanism 100 to convey the alternative fuel package toward the accommodating chamber 210 of the shell 200. When the alternative fuel package enters the feed port 220, the knife shaft device 300 rotates to use the crushing knife group 400 to cut the plastic film and impact and break up the alternative fuel package so that the alternative fuel particles flow out evenly and dispersedly. At least two crushing knife groups 400 contact the alternative fuel package in sequence, which can also realize the functions of cutting the plastic film, impacting and breaking up the alternative fuel package in steps, thereby improving the unpacking efficiency and facilitating the uniform dispersion of the alternative fuel particles. In some use cases, when the first crushing knife group 400 contacts the alternative fuel package, the plastic film can be torn to expose at least part of the agglomerated alternative fuel particles. Then, after the knife shaft device 300 rotates a certain angle, the subsequent crushing knife group 400 impacts the agglomerated alternative fuel particles to disperse and flow out. As the linear conveying mechanism 100 pushes the alternative fuel package forward, the alternative fuel particles can be smoothly broken up and flow out. Of course, the first crushing knife group 400 also has the function of impacting and breaking up the alternative fuel packets.
[0030] See also Figure 1In some embodiments of the utility model, the blade shaft device 300 is located in front of and above the linear conveying mechanism 100, and a feed channel is defined between the outer peripheral wall of the blade shaft device 300 and the loading platform 240, and the crushing blade group 400 contacts the front wall surface of the alternative fuel package so that the broken alternative fuel particles pass through the feed channel. It can be understood that when the alternative fuel package enters the feed inlet 220 and is supported by the loading platform 240, as the linear conveying mechanism 100 continuously conveys the alternative fuel package forward, the front wall surface of the alternative fuel package is torn by the crushing blade group 400 so that the alternative fuel particles can be quickly released and then flow away from the feed channel. In the process of conveying the alternative fuel package forward, the plastic film will be gathered at the outlet position of the alternative fuel particles, and the crushing blade group 400 can break the plastic film into a number of plastic fragments when passing by.
[0031] See also Figure 1 In some embodiments of the present invention, the linear conveying mechanism 100 includes a first conveyor belt 110 arranged in parallel, the first conveyor belt 110 is connected to a first driving mechanism 120 that drives it to rotate around a first clockwise direction to drive the alternative fuel package to approach the knife shaft device 300, the knife shaft device 300 rotates around a second clockwise direction to make the bottom surface of the alternative fuel package pressurized toward the loading platform 240 and the linear conveying mechanism 100, and the first clockwise direction and the second clockwise direction have opposite rotation directions. It can be understood that when the crushing knife group 400 rotates, it abuts against the alternative fuel package, exerting downward pressure on the alternative fuel package, which is conducive to the alternative fuel package to quickly squeeze out the alternative fuel particles after breaking the package, and the linear conveying mechanism 100 and the knife shaft device 300 jointly clamp a part of the alternative fuel package, and the linear conveying mechanism 100 and the knife shaft device 300 have opposite rotation directions to jointly drive the alternative fuel particles after breaking the package to move toward the direction of the feed channel.
[0032] See also Figure 1 In some embodiments of the utility model, the height distance between the axis of the knife shaft device 300 and the linear conveying mechanism 100 is a, and the height dimension of the alternative fuel package is b, which satisfies: 1 / 2b≤a≤b; thereby ensuring that the knife shaft device 300 contacts the middle and upper part of the alternative fuel package when rotating to generate an inclined downward force, which is convenient for breaking up the agglomerated alternative fuel particles. Preferably, the upper end of the outer peripheral wall of the knife shaft device 300 is higher than the upper end of the alternative fuel package, that is, the radial dimension of the knife shaft device 300 is larger to meet the larger area impact that can be generated in the height direction of the alternative fuel package, thereby improving the work efficiency of unpacking and breaking up the alternative fuel package.
[0033] See also Figure 1In some embodiments of the present invention, the inner wall of the housing 200 is provided with a discharge slope 250 matched with the feeding channel, the upper end of the discharge slope 250 butts the feeding channel, the lower part of the housing 200 is provided with a drop pipe 260 connected with the lower end of the discharge slope 250, and the output end of the drop pipe 260 is connected to the elevator 500. It can be understood that the alternative fuel particles discharged from the feeding channel can enter the drop pipe 260 along the discharge slope 250, and then be transferred to the next process through the elevator 500, so as to finally be supplied to the kiln for combustion.
[0034] See also Figure 5 In some embodiments of the utility model, the end of the elevator 500 away from the drop pipe 260 is connected to a drum screen device 600, and the drum screen device 600 can separate the alternative fuel particles from the plastic film. It should be noted that after the alternative fuel package is broken, a number of plastic fragments will be formed, some of which are large in size and will be entangled together or cause the transportation mechanism to be blocked before entering the kiln. The drum screen device 600 can separate materials larger than the preset particle size, and can also separate large plastic fragments to ensure the normal supply of alternative fuel particles to the kiln.
[0035] See also Figure 5 In some embodiments of the utility model, the drum screen device 600 includes an inner drum 610 and a receiving tray 620 located below the inner drum 610. The circumferential wall of the inner drum 610 is covered with pores through which the alternative fuel particles can pass. The outer circumferential walls at both ends of the inner drum 610 are connected with a second driving mechanism that drives the inner drum 610 to rotate. The inner drum 610 is tilted so that the plastic film can be discharged along one end of the inner drum 610. The second driving mechanism is a rotating wheel that abuts against the outer circumferential wall of the inner drum 610. The rotating wheel drives the inner drum 610 to rotate by friction. The drum screen device 600 of the above structure belongs to a shaftless drum screen. Since there is no rotating shaft at the end of the inner drum 610, it is convenient for the plastic film to be discharged from the end of the inner drum 610.
[0036] See also Figure 4In some embodiments of the utility model, the knife shaft device 300 includes a rotating roller, and the multiple knife units 410 of the same crushing knife group 400 are distributed in a "V" shape on the outer peripheral wall of the rotating roller to form a row, and the arrangement direction of the knife units 410 of each crushing knife group 400 is consistent, and the knife unit 410 located at the tip of the "V" shape is in front of the rotation direction of the rotating roller. It can be understood that when one of the crushing knife groups 400 contacts the alternative fuel package first, the knife unit 410 located at the tip of the "V" shape arrangement first forms a smaller cut on the plastic film, and then the knife units 410 on both sides gradually contact the alternative fuel package to expand the cut, which is more conducive to unpacking and prevents jamming.
[0037] See also Figure 4 In some embodiments of the present invention, the tool unit 410 includes a tool holder 411 fixed to the rotating roller, the tool holder 411 has a mounting plane 412 parallel to the axial direction of the rotating roller and arranged along the radial direction of the rotating roller, a quadrangular prism-shaped tool head 413 is detachably mounted on the mounting plane 412, and a first blade 414 is connected between two adjacent side edges of the end face of the tool head 413 away from the mounting plane 412. When in use, a first blade 414 of the tool head 413 protrudes from the contour edge of the tool holder 411 to achieve damage to the plastic film, and when the service life of the first blade 414 ends, another first blade 414 can be replaced by rotating 90°.
[0038] See also Figure 4 In some embodiments of the utility model, the knife seat 411 is provided with a V-shaped limiting groove 415 on one side of the mounting plane 412, the knife head 413 has a plane portion that can fit with the mounting plane 412, two adjacent side walls of the knife head 413 abut against the V-shaped limiting groove 415, a bolt fastener 416 is passed through the knife seat 411 and the knife head 413 in a direction perpendicular to the plane portion, and the side edge of the end face of the knife head 413 away from the mounting plane 412 is bent toward the plane portion so that an angle is formed between the first blade 414 and the corresponding side edge. The V-shaped limiting groove 415 can prevent the knife head 413 from rotating, and the mounting plane 412 and the plane portion abut against each other to prevent the knife head 413 from moving, thereby stably installing the knife head 413. The side edge of the end face of the cutter head 413 away from the installation plane 412 is bent toward the plane portion, so that an angle is formed between the first blade 414 and the corresponding side edge, that is, the cutting structure of the cutter head 413 has a back angle, which improves cutting efficiency.
[0039] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0040] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate 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 claims and their equivalents.
