Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

As shown in fig. 1 and fig. 2, which are schematic views of the overall structure of the nonmetal shredding line of the present invention; the utility model relates to a nonmetal shredding line, which consists of a plurality of conveyors and a plurality of crushers; the crusher at least comprises 1 coarse crusher 2, and the materials are firstly coarsely crushed; then more than 1 fine crusher is arranged according to the characteristics of the materials; in this embodiment, 2 fine crushers are provided, which are respectively named as a middle crusher 4 and a fine crusher 6, and further crush the coarsely crushed material. Therefore, referring to fig. 1 and 2, the utility model discloses a nonmetal shredding line from the input to the output, is feeding chain trigger 1, coarse crusher 2, magnetic separation band conveyer one 3, well breaker 4, magnetic separation band conveyer two 5, smart breaker 6, magnetic separation belt output machine 7 in proper order.

The feeding chain plate machine 1 is positioned at the input end, and cloth strips and plastic film leftover materials to be processed are dispersedly conveyed into a feed hopper of the rough crusher 2 through the feeding chain plate machine 1; the feeding chain plate machine 1, which can be other conveyors or a feeding device, mainly feeds the recycled non-metal waste into the feeding hopper of the coarse crusher 2 in batches and continuously according to the subsequent treatment amount. Because the cloth strips and the plastic film leftover materials are usually wound together in a bulk shape during feeding, even metal objects (such as rivets, drawing pins and the like) are mixed in the cloth strips and the plastic film leftover materials and are difficult to separate, the feeding chain plate machine 1 can be a common chain plate machine and does not have a sorting function.

The coarse crusher 2, the middle crusher 4 and the fine crusher 6 are all double-shaft shredders which are vertically arranged, a feed inlet is positioned above, a double-shaft shredding host is arranged in the middle, a discharge port is arranged at the lower part of the double-shaft shredders, and a conveyor inlet of the next procedure is arranged below the discharge port.

As shown in fig. 3, is a schematic view of the coarse crusher 2; the discharge hole of the feeding chain plate machine 1 is connected with a feed hopper 21 at the top of the coarse crusher 2; the lower part of the feed hopper 21 is provided with a conical hopper 22 for gathering raw materials to a middle coarse shredding cutter shaft 23; the coarse shredding cutter shaft 23 is a rotating shaft with a shredding cutter head, and 2 coarse shredding cutter shafts 23 rotate inwards relatively to form a main machine part of the crusher; the bottom of the coarse shredding cutter shaft 23 is provided with a discharge hopper 24, and crushed materials are collected together and fall onto a feeding hole 31 of the first magnetic separation belt conveyor 3.

As shown in fig. 4, the first magnetic separation belt conveyor 3 conveys the coarsely crushed material into the middle crusher 4 for further processing; the tail end of the first magnetic separation belt conveyor 3 is provided with a magnetic separation roller 32 which can adsorb magnetic metal objects on a belt and then rotate to the lower part; cloth, plastic film etc. after the breakage just drop at the tip of belt further handle in the breaker 4, and magnetic metal is owing to there is magnetic separation roller 32, will move a section distance again along conveyor belt's the back, then leaves the magnetic force effect region back of magnetic separation roller 32, drops again and selects out material slide 33 through magnetism and discharge to avoid ferromagnetic debris to fall into in the breaker 4, cause the destruction to crushing blade. And the material treated by the middle crusher 4 falls on a feeding hole of the second magnetic separation belt conveyor 5 and is conveyed backwards to the fine crusher 6.

As further shown in fig. 5, the second magnetic separation belt conveyor 5 is the same as the first magnetic separation belt conveyor 3, and a magnetic separation roller 32 is arranged at the tail end of the second magnetic separation belt conveyor, so that the crushed material is subjected to magnetic separation again and then falls into the fine crusher 6 for final treatment; and finally, outputting the processed materials by a magnetic separation belt output machine 7 for use.

The main difference of the coarse crusher 2, the middle crusher 4 and the fine crusher 6 is that the blades of the shredding cutter are arranged more and more densely, or the width of the blades of the shredding cutter is smaller and more, so that the particles obtained by shredding the material are smaller and smaller, and finally the particle size of the particle section is smaller than or equal to 45mm multiplied by 45mm, so that the particle size can be directly used as RDF (resource demand formula), the process of making coarse particles is omitted, the manufacturing process is simpler, the RDF treatment cost is lower, and the RDF cost can be effectively reduced.

While the preferred embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that the invention is not limited to the embodiments disclosed, but is capable of numerous equivalents and substitutions without departing from the spirit of the invention, and such equivalents and substitutions are intended to be included within the scope of the invention as defined by the appended claims.
