Description

Technical Field

[0001] The invention belongs to the technical field of construction engineering, and in particular relates to a comprehensive resource utilization device for construction solid waste. Background Art

[0002] Construction waste refers to construction waste generated in the project due to human or natural reasons, including waste soil, abandoned soil, residual mud and abandoned materials. These materials are of no help to the building itself, but they are substances generated in the process of construction and need to be treated accordingly so that the ideal project construction can be achieved. With the acceleration of industrialization and urbanization, the construction industry is also developing rapidly, and the construction waste generated is increasing. If construction waste is piled up for a long time, it will have a bad impact on urban environmental sanitation, living conditions, land quality assessment, etc. In order to meet the concept of sustainable development, the resource utilization of construction waste has become an important part of construction projects.

[0003] In the process of comprehensive resource utilization of construction waste, crushing of construction waste is an indispensable link. For example, a Chinese patent with publication number CN216826394U provides a construction waste resource recycling device, including crushing rollers, mounting holes, position adjustment devices, rotating devices and supporting devices. The surface of the box body is symmetrically provided with mounting holes, and crushing rollers are symmetrically installed on the surfaces of the two mounting holes. The surface of the box body is fixedly connected with a position adjustment device, and the two crushing rollers are rotatably installed with the position adjustment device. The surface of the box body is fixedly connected with a supporting device below one of the mounting holes, and one end of the two crushing rollers is fixedly connected with a rotating device, and the rotating device is fixedly connected to the supporting device. The device can adjust the distance between the two crushing rollers and can crush waste concrete of different block sizes.

[0004] However, as is well known, concrete in construction waste is often mixed in large and small blocks. During the processing, concrete of different sizes is generally crushed at the same time. The above-mentioned device needs to classify the size of the concrete blocks before crushing. It is impossible to uniformly crush concrete blocks of different sizes.

The secondary crushing mechanism 9 is used to realize secondary crushing of the construction solid waste from the primary crushing mechanism.

[0036] Specifically, in the process of crushing construction solid waste, after entering from the feed port 2 of the crushing box 1, the construction solid waste can enter the two extrusion gaps 6 at the same time, and due to the change in the spacing of the extrusion gaps 6 from top to bottom, the extrusion gaps 6 can accommodate different sizes of construction solid waste at the same time, and then, with the cooperation of the thrust assembly 8 and the reset assembly 7, the two second extrusion plates 5 can simultaneously reciprocate in a straight line, so that the second extrusion plate 5 and the corresponding first extrusion plate 4 can realize the extrusion and crushing of the solid waste in the extrusion gap 6, and the extrusion and crushing of the first extrusion plate 4 and the second extrusion plate 5 make the construction solid waste blocks of different sizes realize unified processing, and then the extruded and crushed solid waste falls from the lower end of the extrusion gap 6 to the secondary crushing mechanism 9 for re-crushing, so that the crushing effect is better and resource utilization is convenient, so that the device can firstly realize the unified processing of solid waste of different sizes through the combination of the primary crushing mechanism and the secondary crushing mechanism 9, and improve the crushing effect, and at the same time, the two extrusion gaps 6 set in the primary crushing mechanism can effectively improve the crushing efficiency of the solid waste, and the practicality is better.

[0037] See also Figure 3 and Figure 4 As shown, further, in order to ensure that the solid waste entering from the feed port 2 can completely enter the two extrusion gaps 6. The opposite side walls of the two first extrusion plates 4 are inclined, and a guide block 19 is further provided between the two first extrusion plates 4. The guide block 19 is located on the upper side of the two second extrusion plates 5, and the top wall of the second extrusion plate 5 is in contact with the guide block 19.

[0038] See also Figure 4 and Figure 5 As shown, further, in order to ensure the stable reciprocating movement of the second extrusion plate 5, the reset assembly 7 includes a push block 71, which is slidably connected to the slide groove 72 on the side wall of the crushing box 1, and a tension spring 73 is fixedly connected between the push block 71 and the side wall of the slide groove 72. The extension direction of the tension spring 73 is parallel to the sliding direction of the second extrusion plate 5, and one end of the push block 71 extending out of the slide groove 72 is fixedly connected to the second extrusion plate 5.

[0039] See also Figure 2 and Figure 3 As shown, further, in order to realize the reciprocating linear motion of the two second extrusion plates 5 and repeatedly extrude and crush the solid waste in the two extrusion gaps 6, the thrust assembly 8 includes a motor 81, which is installed on the outside of the crushing box 1. The output shaft of the motor 81 is fixedly connected to a rotating shaft 82 coaxially arranged therewith, and the rotating shaft 82 is inserted between the two second extrusion plates 5. Both ends of the rotating shaft 82 are rotatably connected to the side walls of the crushing box 1. An eccentric wheel 83 is fixedly mounted on the rotating shaft 82, and the axis of the eccentric wheel 83 is perpendicular to the sliding direction of the second extrusion plates 5. The two second extrusion plates 5 are located on opposite sides of the eccentric wheel 83 and are in contact with the circumferential side walls of the eccentric wheel 83.

[0040] Specifically, when in use, the motor 81 drives the eccentric wheel 83 to rotate through the rotating shaft 82. During the rotation of the eccentric wheel 83, the distal end of the eccentric wheel 83 will contact the two second extrusion plates 5 cyclically and alternately during the rotation of the eccentric wheel 83, so that the two second extrusion plates 5 can be pushed back and forth alternately to approach the corresponding first extrusion plates 4 respectively under the rotation of the eccentric wheel 83. When the second extrusion plates 5 move toward the first extrusion plates 4, the push block 71 is driven to slide in the slide groove 72 to stretch the tension spring 73. When the proximal end of the eccentric wheel 83 rotates to one side of the second extrusion plate 5, the tension spring 73 can realize the reset of the second extrusion plate 5 through the reset action. In this way, under the continuous rotation of the eccentric wheel 83, the solid waste in the two extrusion gaps 6 can be continuously extruded and crushed, which not only improves the crushing effect, but also adopts a thrust assembly 8 to realize the crushing method of the two extrusion gaps 6, so that the crushing effect is significantly improved.

[0041] See also Figure 4 and Figure 6As shown, further, in order to better achieve the qualified degree of crushing, realize the unified treatment of solid waste, improve the effect of crushing, and facilitate resource utilization. Among them, the secondary crushing mechanism 9 includes two parallel rotating shafts 91, the two rotating shafts 91 correspond to the two extrusion gaps 6 one by one, both ends of the rotating shaft 91 are inserted through the side wall of the crushing box 1 and are rotatably connected thereto, and both ends of the rotating shaft 91 are connected to the rotating shaft 82 through the first transmission assembly 92, and the first transmission assembly 92 is used to drive the two rotating shafts 91 to rotate synchronously in the opposite direction through the rotation of the rotating shaft 82. The rotating shaft 91 is located on the side wall of the crushing box 1. A plurality of crushing rods 93 are evenly arranged, and the crushing rods 93 on the two rotating shafts 91 are staggered, that is, in the process of the two rotating rods driving the crushing rods 93 to rotate, the crushing rods 93 on both sides will not collide with each other. The rotating shaft 91 and the multiple crushing rods 93 connected to it form a crushing wheel, and the two crushing wheels are arranged one by one on the lower side of the two extrusion gaps 6.

[0042] See also Figure 6 As shown, further, in order to realize the conversion of the power transmission of the motor 81 into the rotational force of the two rotating shafts 91. The first transmission assembly 92 includes a first pulley 921, the first pulley 921 is sleeved on the rotating shaft 82, the first pulley 921 is connected to the second pulley 923 through the first belt 922, the second pulley 923 is sleeved and fixed on the main shaft 924, the main shaft 924 is rotatably connected to the side wall of the crushing box 1, a driving tooth 925 is sleeved and fixed on the main shaft 924, the driving tooth 925 is meshed with a reversing tooth 926, the reversing tooth 926 is rotatably connected to the side wall of the crushing box 1, the driving tooth 925 and the reversing tooth 926 are separated from each other by a driven tooth 927, and the two driven teeth 927 are sleeved and fixed on the corresponding rotating shaft 91.

[0043] Specifically, when in use, after the motor 81 drives the rotating shaft 82 to rotate, the rotating shaft 82 will synchronously drive the main shaft 924 to rotate through the first pulley 921, the second pulley 923 and the first belt 922, and then the main shaft 924 drives the driving tooth 925 to rotate, and the driving tooth 925 can engage with one of the driven teeth 927 to rotate directly, and realize the indirect rotation of the other driven tooth 927 through the reversing tooth 926, thereby realizing that the two driven teeth 927 drive the two rotating shafts 91 to rotate, and then the two rotating shafts 91 will drive the crushing rod 93 to crush the solid waste from the extrusion gap 6 again, and the qualified waste after crushing is discharged from the discharge port 3 of the crushing box 1. It is better that the two rotating shafts 91 drive the crushing rods 93 to rotate towards each other under the action of the reversing teeth 926, and the two crushing wheels rotate towards each other. Through the opposite movement of the two crushing wheels, the solid waste falling between the two crushing wheels can collide with each other between the two crushing wheels under the action of centrifugal force, thereby achieving repeated impact and crushing of the solid waste, making the crushing effect better and facilitating resource utilization.

[0044] See also Figure 3 As shown, further, in order to make the solid waste entering between the crushing bars 93 be crushed more thoroughly and improve the crushing effect, a crushing hammer 20 is fixedly connected to the end of each crushing bar 93 away from the rotating shaft 91, and a plurality of crushing teeth 21 are arranged on the side wall of the crushing hammer 20.

[0045] When in use, the rotating rod drives the crushing rod 93 to rotate. Under the high-speed rotation of the crushing rod 93, the crushing hammer 20 will collide with the solid waste in advance, and the impact force of the collision is greater. In addition, the crushing teeth 21 are arranged on the crushing hammer 20 to crush the solid waste more effectively, thereby improving the crushing effect.

[0046] See also Figures 4 to 8 As shown, further, in order to achieve a better crushing effect, it is to avoid damage to the crushing rod 93 caused by metal materials mixed in the solid waste, and to improve the effect of resource utilization. Side boxes 10 are also fixedly connected to the opposite sides of the crushing box 1, and the two side boxes 10 are connected to the cavity of the crushing box 1, and each side box 10 is provided with a transmission belt 11 at the connection part with the cavity of the crushing box 1. Preferably, the transmission belt 11 is located in the space reserved between the rotating shaft 91 and the second extrusion plate 5, and the transmission surface of the transmission belt 11 facing the crushing box 1 is vertically arranged. Transmission shafts 12 are provided at both ends of the transmission belt 11. The transmission shaft 12 is rotatably connected to the side wall of the side box 10, and one of the transmission shafts 12 is connected to the corresponding rotating shaft 91 through the second transmission assembly 13; further, as Figure 7 and Figure 8 As shown, a plurality of electromagnetic adsorption plates 14 are fixedly connected at equal intervals on the belt surface of the transmission belt 11, an infrared transmitter 15 is fixedly connected to the same side of the plurality of electromagnetic adsorption plates 14, an infrared receiving board 16 is fixedly connected to the side wall of each side box body 10, and the infrared receiving board 16, the infrared transmitter 15 and the electromagnetic adsorption plate 14 are electrically connected to the controller 17.

[0047] See also Figure 3 As shown, further, in order to realize the operation of the transmission belt 11. The second transmission assembly 13 includes a third pulley 131, the third pulley 131 is fixedly mounted on the rotating shaft 91, the third pulley 131 is connected to a fourth pulley 133 through a second belt 132, and the fourth pulley 133 is fixedly mounted on a corresponding transmission shaft 12. In addition, preferably, two protective shells are respectively arranged on both sides of the crushing box 1, and the first transmission assembly 92 and the second transmission assembly 13 are both arranged inside the shells, which can effectively protect the components.

[0048] Specifically, when in use, the solid waste falling from the extrusion gap 6 will first be adsorbed by the electromagnetic adsorption plate 14 for the metal materials mixed in the waste before contacting the crushing rod 93, so that the solid non-metallic materials are separated from the metal materials, that is, only the solid non-metallic materials are retained when reaching the crushing rod 93. At this time, it can effectively prevent the metal materials from entering between the crushing rods 93 and causing damage to the crushing rods 93. After the electromagnetic adsorption plate 14 adsorbs the metal materials, it will rotate along with the transmission belt 11, so that the electromagnetic adsorption plate 14 facing the crushing box 1 will rotate to the side box body 10. After the electromagnetic adsorption plate 14 enters the side box body 10, the infrared signal emitted by the infrared transmitter 15 connected to the electromagnetic adsorption plate 14 will hit On the infrared receiving board 16, when the infrared receiving board 16 receives the infrared signal, it will immediately feed back to the controller 17, and the controller 17 will cut off the power of the corresponding electromagnetic adsorption board 14, so that the metal material adsorbed on the electromagnetic adsorption board 14 falls into the side box body 10 and is discharged from the outlet of the side box body 10. In order to avoid the electromagnetic adsorption board 14 causing secondary adsorption of the metal material in the side box body 10, the vertical height of all electromagnetic adsorption boards 14 can be consistent with the entire belt surface of the transmission belt 11 entering the side box body 10, which can ensure that the electromagnetic adsorption board 14 is continuously powered off in the side box body 10, and when the electromagnetic adsorption board 14 leaves the side box body 10 and enters the side of the crushing box 1, it can be powered on again to adsorb the metal material, which is convenient for use.

[0049] See also Figure 4 and Figure 5 As shown, further, in order to improve the crushing effect of solid waste and facilitate the truncation of metal materials in solid waste, so that the waste can be discharged smoothly from the lower end of the extrusion gap 6, the first extrusion plate 4 and the second extrusion plate 5 have a plurality of shearing teeth 18 fixedly connected at equal intervals along the vertical direction on the impact surface relative to each other, and the shearing teeth 18 on both sides are staggered. Preferably, the shearing teeth 18 arranged between the first extrusion plate 4 and the second extrusion plate 5 form a pliers-like structure, which can achieve the effect of crushing block-shaped solid waste when crushing solid waste, and can also crush metal materials and materials with greater hardness, with better crushing effect.
