Description

Technical Field

[0001] The invention relates to the technical field of construction waste recycling devices, in particular to a construction waste recycling device for building construction. Background Art

[0002] Construction waste refers to solid waste generated during the construction, reconstruction, expansion and demolition of buildings. It mainly includes construction debris, construction mud, construction waste, demolition waste and decoration waste. Its composition is complex, and common ones include concrete, mortar, bricks and stones, metal, wood, plastic, glass, etc.

[0003] Chinese patent (Announcement No.: CN118558401A), the scheme specifically includes: a processing component, a roller component, a first coil component, a second coil component and a controller, the processing component is used to contain construction waste, so as to collect the construction waste in a centralized manner; the roller component is arranged in the processing component to crush the construction waste into aggregates, because the construction waste includes metal waste and non-metal waste, and after the construction waste is crushed, it will also include magnetic aggregates and non-magnetic aggregates, for example, after the reinforced concrete is crushed, the steel aggregate and the concrete aggregate are obtained; the first coil component and the second coil component are used to suck out the magnetic aggregate, so that the magnetic aggregate is separated from the non-magnetic aggregate, and the magnetic aggregate can be continuously adsorbed. The construction waste recycling and processing device in this embodiment can efficiently separate the magnetic aggregate and the non-magnetic aggregate, and improve the separation efficiency. The present invention is applied to the field of construction waste recycling.

[0004] In the process of construction waste treatment, existing construction waste recycling devices usually use crushing rollers to crush construction waste. However, the composition of construction waste is complex, including natural stones, plastics, glass and other smooth objects from demolished old buildings or roads. These smooth objects are very easy to slip during the crushing process of the crushing rollers, making it difficult to be effectively clamped and crushed.

[0005] Among them, when the above patent uses a crushing roller to crush construction waste, it is difficult to deal with the garbage that has slippage. The slippage phenomenon makes it impossible for the garbage to fully contact the crushing roller, resulting in prolonged crushing time and reduced crushing speed. The crushing roller requires more time and energy to process the same amount of garbage, thereby reducing the overall garbage crushing efficiency. Therefore, a construction waste recycling device for construction is proposed. Summary of the invention

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Please refer to Figures 1 to 11 , the present invention provides a technical solution: a construction waste recycling device for construction, including an outer frame body 1 and a plurality of crushing rollers 2 thereon for crushing construction waste. A water tank and a spray pipe 29 for spraying the water source in the water tank are provided on the outer frame body 1. Two groups of parallel arranged crushing rollers 2 are a set of crushing components. A middle seat 3 is fixedly connected to the middle part of the inner wall of the outer frame body 1. A set of crushing components is respectively arranged on the horizontal left and right sides of the middle seat 3, and the crushing parameters of the crushing rollers 2 in the two groups of crushing components are different. A shifting mechanism is provided on the outer frame body 1 to adjust the construction waste that shows a slipping phenomenon to slide to the adjacent crushing component

[0040] The shifting mechanism includes a plurality of U-shaped frames 4 arranged in one-to-one correspondence below the plurality of crushing rollers 2 and used for supporting the crushing rollers 2. A set of positioning rods 12 are respectively fixedly connected to the two sides of the outer frame body 1 corresponding to the axes of the two groups of crushing components. A middle swing component is provided on the positioning rod 12 to drive the crushing rollers 2 in the two groups of crushing components to swing intermittently and alternately towards one side of the middle seat 3

[0041] Both ends of the crushing roller 2 are rotationally fixed on the U-shaped frame 4. Ball head shafts 5 are coaxially fixed at the ends of the crushing rollers 2 in the two groups of crushing components facing the middle seat 3, and a ball cavity 6 for slidably connecting the ball head shafts 5 is opened on the middle seat 3

[0042] A dust spraying component is provided on the inner wall of the outer frame body 1 to drive the water source in the water tank to spray out from the spray pipe 29 to reduce the amount of dust escaping

[0043] As Figures 1 - 3 shown, the concrete blocks, crushed stones and other construction waste generated by demolishing old buildings can be used as recycled aggregates during recycling treatment, and can be used to replace natural aggregates to prepare building materials such as recycled concrete, mortar or blocks. When recycling this kind of waste, it needs to be crushed first. Among them, this kind of construction waste is put into two groups of crushing components arranged in the outer frame body 1. Each group of crushing components is composed of two crushing rollers 2 that rotate synchronously and in opposite directions. Then, the construction waste is crushed by the plurality of crushing rollers 2

[0044] Meanwhile, in order to reduce the sliding phenomenon of construction waste during the crushing process, the crushing parameters of the two groups of crushing components are different. Among them, the crushing parameters include, but are not limited to, different spacings, clamping angles, and rotational speeds of the two groups of crushing rollers 2 provided in the two groups of crushing components. At the same time, the middle swing component drives the crushing rollers 2 in the two groups of crushing components to swing alternately in the vertical direction, and the swinging directions of the crushing rollers 2 are all towards the side where the middle seat 3 is located. That is, when the crushing roller 2 in one group of crushing components swings, its toe direction faces the other group of crushing components in a horizontal state. Thus, it can drive the construction waste that shows a sliding phenomenon on one group of crushing components to slide down to the adjacent other group of crushing components under the action of gravity. Therefore, the construction waste can be crushed by the crushing components with different crushing parameters to reduce the problem that the waste still shows a sliding phenomenon.

[0045] Among them, when the construction waste in one group of crushing components shows a sliding phenomenon due to its shape or material, these sliding wastes can be transferred to another group of crushing components with different crushing parameters. Due to the different crushing parameters of the other group of crushing components, these sliding wastes may be more easily clamped and crushed, thus effectively reducing the space occupation problem caused by the sliding phenomenon of construction waste.

[0046] Moreover, during the actual use process, the construction waste that shows a sliding phenomenon will stay at the crushing roller 2 and is difficult to be crushed. Furthermore, it will affect the subsequent crushing of the waste by the crushing roller 2 here. Therefore, by reducing the amount of waste that shows a sliding phenomenon, it can make the waste fully contact with the crushing roller 2 to improve the crushing efficiency.

[0047] Meanwhile, a large amount of dust will be generated during the crushing process of construction waste. These dusts will not only pollute the environment but also may pose a hazard to the health of the operators. Therefore, through the dust spraying component, the water source in the water tank can be driven to spray out from multiple groups of atomizing nozzles provided on the spray pipe 29. Thus, the dust particles can be combined with the atomized water vapor to make them settle, thereby improving the working environment, reducing the pollution to the surrounding air, and effectively reducing the generation and diffusion of dust.

[0048] Furthermore, the crushing roller 2 freely swings in the vertical direction with the ball head shaft 5 as the swinging center point. An arc-shaped block 30 is provided at one end of the U-shaped frame 4 away from the ball head shaft 5. The crushing roller 2 rotates on the arc-shaped block 30 in a fixed-axis manner, and an arc-shaped groove 31 for the arc-shaped block 30 to slide and connect is formed on the outer frame body 1.

[0049] Such as Figure 1 and Figure 8As shown, when the U-shaped frame 4 swings in the vertical direction, it can drive the crushing roller 2 provided thereon to swing synchronously. When the crushing roller 2 swings in the vertical direction, it takes the ball head shaft 5 as the swing center point. By arranging a ball cavity 6 on the middle seat 3, it can ensure that the swinging process of the crushing roller 2 will not be interfered, and can synchronously meet the rotation requirement of the crushing roller 2.

[0050] Meanwhile, when the U-shaped frame 4 drives the crushing roller 2 to swing, it can drive the arc-shaped block 30 arranged at its end to rotate synchronously. Among them, the arc-shaped block 30 is slidably arranged on the inner wall of the outer frame 1 through the arc groove 31. Then, when the crushing roller 2 is in the initial state, that is, the horizontal state, the arc-shaped block 30 can support the U-shaped frame 4 and the crushing roller 2, and can adapt to the angle change process of the crushing roller 2 through the sliding process of the arc-shaped block 30 on the arc groove 31.

[0051] In one relatively preferred embodiment, the middle swing assembly includes a plurality of bottom bases 8 respectively arranged below a plurality of U-shaped frames 4. A coaxial seat 7 is rotatably fixed on the bottom base 8, and a rectangular groove for the U-shaped frame 4 to be slidably connected is opened on the coaxial seat 7;

[0052] Two groups of transverse connecting shafts 9 are respectively fixedly connected to the plurality of bottom bases 8. A side position sliding column 10 and an inner position sliding column 11 are respectively fixedly connected to the two groups of transverse connecting shafts 9. A guiding groove 13 for the side position sliding column 10 and the inner position sliding column 11 to be slidably connected is opened on the positioning rod 12, and a notch groove 14 communicating with the positioning rod 12 is also opened on the positioning rod 12. When the inner position sliding column 11 is at the end position of the guiding groove 13, it deflects in the vertical direction along with the horizontal movement of the bottom base 8.

[0053] A flat position rod 16 that moves freely in the horizontal direction is arranged on the outer frame 1. Both ends of the flat position rod 16 include integrally formed end extension parts 161. A groove body one for the flat position rod 16 to be slidably connected is opened on the inner wall of the outer frame 1;

[0054] A side extension rod 15 slidably penetrates through the guiding groove 13. The side extension rod 15 is fixedly connected with the bottom base 8. A tuning pin 17 is fixedly connected to the end of the side extension rod 15 away from the bottom base 8, and a tuning groove 18 for the tuning pin 17 to be slidably connected is opened on the end extension part 161.

[0055] A central gear 19 that rotates freely in the vertical direction driven by a motor is arranged on the positioning rod 12. The central gear 19 is rotatably fixed on the positioning rod 12 and meshes with a rack 20. The rack 20 and the flat position rod 16 are fixedly connected to each other.

[0056] As Figures 1 - 7As shown, the central gear 19 connected to the motor output shaft by the motor fixed on the positioning rod 12 is driven to rotate freely in the vertical direction, thereby driving the rack 20 meshing with the central gear 19 to move freely in the horizontal direction, wherein the direction of movement of the rack 20 and the horizontal rod 16 thereon is changed by controlling the direction of rotation of the motor output shaft, thereby freely adjusting the horizontal movement direction of the horizontal rod 16 and the two groups of end extensions 161 at its ends.

[0057] At the same time, in the initial state, the two groups of U-shaped frames 4 are in a horizontal state, and thus the crushing rollers 2 thereon are synchronously in a horizontal state. When the leveling rod 16 moves toward the right side in the horizontal direction, the adjustment pin 17 and the side extension rod 15 can be pushed to move horizontally synchronously through the adjustment groove 18 opened thereon, thereby driving the two groups and the U-shaped frames 4 set thereon to move horizontally synchronously.

[0058] When the inner slide post 11 at the bottom base 8 on the left side moves to the right end position of the guide groove 13, as the horizontal rod 16 continues to move horizontally to the right, at this time, since the bottom base 8 on the right side can continue to move horizontally, while the bottom base 8 on the left side cannot continue to move horizontally due to the restriction of the inner slide post 11 thereon, the horizontal rod 16 can drive the side extension rod 15 to slide on the adjustment groove 18 during the horizontal rightward movement at this time, and then drive the bottom base 8 to deflect in the vertical direction through the side extension rod 15.

[0059] At the same time, when the bottom base 8 deflects, the U-shaped frame 4 on it can be driven to swing with the center of the ball head shaft 5 as the swing center point, and because the swing center points of the bottom base 8 and the crushing roller 2 are different, in order to ensure that the bottom base 8 can always support the U-shaped frame 4, a fixed-axis rotating isotope 7 is provided on the bottom base 8 to compensate for the amplitude difference caused by the different swing center points of the two, and to ensure that when the bottom base 8 swings with the position of the inner sliding column 11 as the center, the crushing roller 2 on it can be driven by the U-shaped frame 4 to deflect with the ball head shaft 5 as the center, and the U-shaped frame 4 is supported by the isotope 7 to ensure the stability of the U-shaped frame 4 when the angle changes.

[0060] Among them, when the horizontal rod 16 moves horizontally to the right, it can drive the crushing assembly on the left to swing, so that the garbage that slips on the left crushing assembly can slide to the right crushing assembly. Similarly, when the horizontal rod 16 continues to move horizontally to the left, it can change the horizontal angle of the crushing assembly on the right, thereby achieving the purpose of moving the construction waste on the two groups of crushing assemblies, to ensure that the garbage with slippage can enter the crushing assembly with different crushing parameters, thereby reducing the amount of garbage with slippage that stops on the crushing roller 2, thereby improving the garbage treatment efficiency.

[0061] It should be noted that a notch groove 14 penetrating the guide groove 13 is provided on the positioning rod 12, and the notch groove 14 is provided to meet the swinging process of the side extension rod 15 and the side sliding column 10, so as to provide a clearance space for the swinging process of the two, so as to avoid interference caused by the existence of the positioning rod 12 in its swinging process.

[0062] Based on the embodiment of the mid-swing assembly, the dust spray assembly includes two sets of mounting blocks 26 fixedly connected to the outer frame 1, and a set of tooth columns 25 are provided on the two sets of mounting blocks 26, and a circular groove for the tooth columns 25 to slide through is opened on the two sets of mounting blocks 26;

[0063] A group of piston plates 28 are fixedly connected to both ends of the tooth column 25, and a sealing cylinder 27 in gas communication with the water tank is fixedly connected to the outer frame 1 corresponding to the position of the piston plate 28, and the outer peripheral surface of the piston plate 28 is in sliding contact with the inner wall of the sealing cylinder 27.

[0064] The sealing tube 27 includes an integrally formed liquid inlet end and a liquid outlet end. The liquid inlet end is in gas communication with the water tank, and the liquid outlet end is in gas communication with the nozzle 29.

[0065] The outer frame 1 is provided with a rocker arm 21, and the middle part of the rocker arm 21 is fixedly rotated on the outer frame 1, a center gear 19 is fixedly connected with a co-ordination pin 22 on one side facing the rocker arm 21, and a co-ordination groove 23 for sliding connection of the co-ordination pin 22 is provided on the rocker arm 21, and a sector gear 24 is fixedly connected with one end of the rocker arm 21 away from the co-ordination groove 23, and the sector gear 24 is meshingly connected with the tooth column 25.

[0066] like Figure 2 , Figure 3 and Figure 9 As shown, when the center gear 19 rotates in the vertical direction, the horizontal position of the isochronous pin 22 fixed thereon can be changed, wherein the isochronous pin 22 is slidably connected to the rocker arm 21 through the isochronous groove 23, and the middle fixed axis of the rocker arm 21 rotates on the outer frame 1, and then when the center gear 19 rotates, it can drive the rocker arm 21 to swing through the position change of the isochronous pin 22.

[0067] At the same time, the fan gear 24 arranged at the end of the rocker arm 21 is meshedly connected with the gear column 25, and a group of piston plates 28 are fixedly arranged at the ends of the gear columns 25, and the two groups of piston plates 28 are respectively located in the two groups of sealing cylinders 27, so that no matter what the horizontal movement direction of the gear column 25 is, there is a group of piston plates 28 arranged at the end that can squeeze the water source in the corresponding sealing cylinder 27 and push the water source to the nozzle 29, so as to be sprayed out through multiple groups of atomizing nozzles fixedly connected on the nozzle 29, so as to reduce the dust generated in the crushing process, thereby reducing the escape amount of dust in the outer frame 1.

[0068] Among them, the liquid inlet end and the liquid outlet end are provided on the envelope 27, and a set of one-way valves are respectively provided on the liquid inlet end and the liquid outlet end. The valve ports of the two sets of one-way valves are opposite. Thus, when the tooth column 25 drives the piston plate 28 to move horizontally, the flow direction of the water source can be restricted, so as to drive the water source to flow from the water tank into the envelope 27 and be pressed from the envelope 27 to the spray pipe 29.

[0069] It should be noted that during the actual use process, when the construction waste does not slip on the two sets of crushing components, that is, when there is no need to drive the angle adjustment of a single set of crushing components, the rack 20 can be driven to reciprocate within a small stroke range in the horizontal direction. Then, through the rotation process of the central gear 19, the dust spraying component is driven to operate. At the same time, it can be ensured that the inner sliding column 11 will not continue to move horizontally after reaching the terminal position of the guiding groove 13, so as to avoid the deflection of the bottom base 8 in the vertical direction and avoid the phenomenon that the angle of a single set of crushing components changes.

[0070] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
