Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a green building construction waste recycling and sorting device. Background Technology

[0002] Green building construction waste refers to all kinds of solid waste generated during the entire life cycle of a green building project, from planning and design to construction, decoration and demolition. It mainly includes broken bricks, concrete blocks, waste steel bars, wood scraps, plastic waste, slag, waste paint and packaging materials generated during construction. Due to the special requirements of green buildings for environmental protection, energy conservation and resource recycling, these wastes need to be collected in a classified manner, treated in a resource-based manner or disposed of in compliance with regulations in order to reduce environmental pollution and improve resource utilization efficiency. It is an important manifestation of the sustainable development concept of green building in the construction stage.

[0003] Green building construction waste recycling and sorting systems are specifically designed for green building construction scenarios. They are equipment or systems used for the precise sorting, temporary storage, and preliminary treatment of various wastes generated during construction, such as broken bricks, concrete blocks, scrap steel bars, wood scraps, and plastic waste. These systems include different types of sorting and collection containers, sorting and conveying devices, and crushing and screening equipment. Through clear signage guidance and physical sorting or mechanical separation, they achieve source separation of waste, laying the foundation for subsequent resource recycling. They are key facilities for implementing the concept of green building resource recycling and reducing environmental pollution. However, the composition of construction waste... The current equipment is complex and ineffective at sorting low-value, irregularly shaped, or tightly mixed materials. Existing technologies employ a multi-stage air classifier combined with electrostatic adsorption for sorting: first, a horizontal air classifier separates wood chips; then, a vertically rising air classifier uses the large surface area of ​​the plastic film to suspend and separate it; finally, a high-voltage electrostatic separator adsorbs the remaining fine plastic fragments. Concrete particles, being uncharged, fall directly, thus improving the plastic recycling rate. However, when large pieces of concrete or clumps of material enter the air classifier or electrostatic separator, it causes blockage of the airflow channels, affecting the normal operation of the equipment and reducing its service life.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a green building construction waste recycling and sorting device, comprising a body 1, a pre-treatment mechanism 3 installed on the top of the body 1 for preliminary crushing of waste, a conveyor belt 4 installed on the left side of the body 1, a dispersing mechanism 2 installed on the top of the conveyor belt 4 for dispersing the crushed waste; the pre-treatment mechanism 3 includes a treatment tank 308, which is installed at the top center of the body 1, a second motor 301 installed on the rear side of the treatment tank 308, a first rotating rod 302 fixedly connected to the output end of the second motor 301, a second rotating rod 309 rotatably connected to the inner left end of the treatment tank 308, rotating circular plates 304 fixedly connected to the right sides of both the second rotating rod 309 and the first rotating rod 302, and multiple crushing blades 303 fixedly connected at equal intervals to the outer sides of both the second rotating rod 309 and the first rotating rod 302, through the installation of the crushing blades 303... It is capable of preliminary crushing of waste. The front side of the rotating circular plate 304 is rotatably connected to the connecting bent rod 305. The rear side of the second rotating rod 309 is equipped with a pushing assembly 306. The inner side of the machine body 1 is equipped with a reset assembly 307. The pushing assembly 306 includes a rotating short column 3061, which is fixedly connected to the rear side of the second rotating rod 309. The bottom of the rotating short column 3061 is fixedly connected to a connecting rope 3062. The bottom of the pushing assembly 306 is fixedly connected to a pushing plate 3063. The front and rear ends of the pushing plate 3063 are fixedly connected to sliding blocks 3064. The front and rear ends of the inner side of the machine body 1 are provided with sliding square grooves 3065. The reset assembly 307 includes two springs 3072, which are fixedly connected to the front and rear ends of the right side of the pushing plate 3063. The outer side of the springs 3072 is equipped with protective sleeves 3071 to prevent unnecessary damage to the springs 3072.

[0032] Specifically, the second motor 301 is started, driving the first rotating rod 302 to rotate. Through the installation of the rotating circular plate 304 and the connecting bent rod 305, the second rotating rod 309 is rotated. Through the installation of multiple crushing blades 303, the waste is effectively crushed. At the same time, the second rotating rod 309 drives the rotating short column 3061 to rotate, causing the connecting rope 3062 to wind around, thereby pulling the push plate 3063 to move. The push plate 3063 slides smoothly in the sliding square groove 3065 to avoid instability during the movement. By installing the spring 3072, the push plate 3063 can be easily reset.

[0033] Reference Figure 1 , Figure 3 and Figure 5The dispersing mechanism 2 includes a first motor 201, which is installed at the top center of the conveyor belt 4. A rotating plate 202 is fixedly connected to the output end of the first motor 201. Both the first motor 201 and the second motor 301 are model Z630-10 / 1180. Their working principle is that the stator generates a constant main magnetic field. After DC current is applied to the armature winding, it is subjected to electromagnetic force in the magnetic field, forming a rotating torque. The commutator ensures that the torque direction is constant, achieving a stable conversion of electrical energy to mechanical energy. Slide plates 205 are fixedly connected to the front and rear ends of the left side of the machine body 1. A connecting plate 204 is fixedly connected to the middle of the slide plate 205. A rotating cylinder 203 is rotatably connected to the bottom of the rotating plate 202. The bottom of the rotating cylinder 203 is connected to the top of the connecting plate 204. The rotating plate 202 has a sliding groove 207 at the bottom center. The sliding groove 207 has sliding short columns 206 at both the front and rear ends of the inner side of the sliding groove 207. The bottom of the sliding short columns 206 is fixedly connected to a dispersing plate 208. The top outer side of the dispersing plate 208 is slidably connected to the bottom of the sliding groove plate 205. The bottom front and rear ends of the conveyor belt 4 are fixedly connected to a support plate 8. The left side of the conveyor belt 4 is equipped with a processing device 5, model YPS-100. Its working principle is that the vibrating feeder feeds the material into the impact crusher at a uniform speed. The motor drives the rotor of the impact crusher to rotate at high speed. The material is crushed by impact with the hammers on the rotor and then impacted onto the liner for further crushing. This process is repeated until the required particle size is reached and then discharged from the outlet.

[0034] Specifically, the first motor 201 is started, driving the rotating plate 202 to rotate. During the rotation, the rotating cylinder 203 rotates around the connecting plate 204. Through the opening of the sliding groove 207, the two sliding short columns 206 move synchronously. Since the sliding short columns 206 are connected to the dispersing plate 208, the dispersing plate 208 can move left and right. The dispersing plate 208 slides smoothly along the bottom of the sliding groove plate 205, avoiding unnecessary shaking. It can evenly disperse the crushed waste on the conveyor belt 4, providing a guarantee for the smooth progress of subsequent processes.

[0035] Reference Figure 1 , Figure 2 and Figure 3 The processing device 5 and the bottom of the body 1 are both fixedly connected with multiple support columns 6 at equal intervals. The bottom of the support column 6 is fixedly connected with a support base 7. The top of the body 1 is connected with a flow pipe 9. The middle of the inner side of the body 1 is fixedly connected with a filter plate 13. The left and right ends of the rear top of the body 1 are both equipped with support rods 11. The top of the support rods 11 is fixedly connected with a support square plate 10. The rear side of the body 1 is fixedly connected with multiple fixed blocks 12 at equal intervals.

[0036] Specifically, the installation of the support column 6 makes the processing device 5 and the body 1 more stable, the installation of the filter plate 13 enables preliminary filtration of the crushed waste, and the installation of the fixing block 12 limits the movement of the connecting rope 3062.

[0037] Working principle: Turning on the second motor 301 causes the first rotating rod 302 to rotate. Through the installation of the rotating circular plate 304 and the connecting bent rod 305, the second rotating rod 309 can be driven to rotate. Through the installation of multiple crushing blades 303, the waste is crushed. At the same time, the second rotating rod 309 drives the rotating short column 3061 to rotate, so that the connecting rope 3062 is wound around and pulls the push plate 3063 to move. The push plate 3063 slides in the sliding square groove 3065, thereby avoiding unstable movement. The installation of the spring 3072 facilitates the return of the push plate 3063 to its original position.

[0038] The first motor 201 is turned on, causing the rotating plate 202 to rotate. During the rotation, the rotating cylinder 203 rotates on the connecting plate 204. At the same time, the two sliding short columns 206 are moved by the opening of the sliding groove 207. Since the sliding short columns 206 are connected to the dispersing plate 208, the dispersing plate 208 can move left and right. Since the dispersing plate 208 slides along the bottom of the sliding groove plate 205, unnecessary shaking of the dispersing plate 208 is avoided, thereby dispersing the crushed waste on the conveyor belt 4, which facilitates the operation of subsequent processes.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
