Description

Technical Field

[0001] This utility model relates to the field of construction waste recycling technology, specifically to a construction waste recycling and cleaning device. Background Technology

[0002] Against the backdrop of accelerated urbanization and urban renewal, the construction industry continues to expand, and the output of construction waste is rising accordingly. Among them, construction formwork waste, as an important component of demolition and decoration waste, accounts for a significant proportion of the annual output. If such waste is not properly treated and is directly piled up or landfilled, it will not only occupy a large amount of land resources, but the impurities it contains may also pollute the soil and groundwater through leachate, exacerbating the pressure on the ecological environment. Meanwhile, construction formwork waste has high recycling value. Through crushing, it can be transformed into recycled raw materials and put back into production. This can reduce the need for mining new resources and create significant economic and environmental benefits, thus becoming one of the key directions for the resource utilization of construction waste.

[0003] Existing waste formwork crushing equipment mostly relies on single-stage or simple multi-stage crushing structures. Although it can achieve preliminary crushing, it generally suffers from insufficient particle size control precision. Some larger particles that are not fully crushed are easily stuck on the surface of the filter structure. If not handled in time, it will cause the filter channel to become blocked, which will not only reduce the crushing efficiency, but also allow unqualified particles to be mixed into the finished product, affecting the quality of subsequent recycling and making it difficult to meet the needs of fine recycling. For example, a waste recyclable formwork recycling and regeneration equipment disclosed in application number CN202322777146.4 has the above-mentioned problems. Utility Model Content

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0017] The present invention will be further described below with reference to the embodiments.

[0018] Example: Refer to Figures 1 to 3 A construction waste recycling and cleaning device includes a recycling bin 1, a feed inlet 2 at the top of the recycling bin 1, a feed frame 3 fixedly connected to the top of the recycling bin 1, the feed frame 3 being wider at the top and narrower at the bottom, a rotating rod rotatably connected to the inner wall of the recycling bin 1, a plurality of circular cutting blades 4 fixedly connected to the outer wall of the rotating rod, a first motor 5 fixedly connected to the outer wall of the recycling bin 1, and the output end of the first motor 5 being fixedly connected to the rotating rod.

[0019] The inner wall of the recycling bin 1 is fixedly connected to two symmetrical fixing blocks 6, and a cutting frame 7 is fixedly connected between the two fixing blocks 6. The inside of the cutting frame 7 is wider at the top and narrower at the bottom.

[0020] Two cutting grooves 8 are symmetrically and alternately opened on opposite sides of the outer wall of the cutting frame 7, and a rectangular cutting blade 9 is slidably connected to the inner wall of the cutting groove 8.

[0021] Two rectangular cutting blades 9 are fixedly connected to the outer walls of a connecting rod 10, and a toothed plate 11 is fixedly connected to the outer wall of the connecting rod 10. The teeth of the two toothed plates 11 are opposite to each other. A second motor 12 is fixedly connected to the inner wall of the recycling box 1. A gear 13 is fixedly connected to the output end of the second motor 12. The gear 13 meshes with the two toothed plates 11.

[0022] The inner wall of the recycling bin 1 is movably connected to a cutting roller 14. The outer wall of the recycling bin 1 is fixedly connected to two third motors 15 for driving the cutting roller 14, and the two third motors 15 drive in opposite directions. The outer walls of the two cutting rollers 14 are fixedly connected to cutting blades 16, and the cutting blades 16 on the two cutting rollers 14 are staggered. The outer wall of the cutting roller 14 is provided with multiple sliding grooves 17, and each sliding groove 17 is located between every two cutting blades 16. The inner walls of the multiple sliding grooves 17 are jointly provided with a moving groove 18. The inner wall of the moving groove 18 is fixedly connected to two symmetrical miniature electric telescopic rods 19. The telescopic end of the miniature electric telescopic rod 19 is fixedly connected to a push plate 20. The top end of the push plate 20 is fixedly connected to multiple actuating blocks 22, and the actuating blocks 22 are slidably connected to the inner wall of the sliding groove 17.

[0023] Two symmetrical arc-shaped filter screens 21 are fixedly connected to the inner wall of the recycling bin 1, and the two arc-shaped filter screens 21 surround the two cutting rollers 14. After the actuating block 22 is pushed out, it contacts the outer wall of the arc-shaped filter screen 21.

[0024] The working principle of this utility model is as follows: When recycling construction template waste, the waste is first fed into the recycling bin 1 through the inlet 2 at the top, and guided into the bin by the feed frame 3, which is wider at the top and narrower at the bottom. The first motor 5 is started, which drives the rotating rod and multiple circular cutting blades 4 to rotate, initially crushing the waste into wood strips.

[0025] The broken wood strips fall into the cutting frame 7 (wider at the top and narrower at the bottom) fixed by the fixing block 6 under the action of gravity. The second motor 12 is started, and the gear 13 at its output end drives the rectangular cutting blades 9 with toothed plates 11 on both sides to slide relative to each other along the cutting groove 8, cutting the wood strips symmetrically from both sides to form smaller segments.

[0026] These fragments fall to the two cutting rollers 14, and the two third motors 15 drive the cutting rollers 14 to rotate in opposite directions. The staggered cutting blades 16 on the outer wall further cut the fragments into fine particles. During cutting, the miniature electric telescopic rod 19 operates according to a preset action: when the actuating block 22 rotates from directly below the cutting roller 14 to directly above and contacts the arc-shaped filter screen 21, the telescopic rod extends, pushing the actuating block 22 to extend along the sliding groove 17, pushing the larger particles that have not passed through the arc-shaped filter screen 21 back between the two cutting rollers 14 for re-crushing; at other times, the actuating block 22 retracts without affecting the cutting.

[0027] Finally, particles that meet the required size fall into the bottom of the inclined recycling bin 1 after being filtered by the arc-shaped filter screen 21, and are discharged from the outlet along the inclined surface, completing the recycling process.

[0028] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it.
