Description

Technical Field

[0001] This invention relates to the field of building material waste crushing technology, specifically to a crushing and processing device for building material waste from construction sites. Background Technology

[0002] Construction site waste mainly includes the following types of building materials: wood-based panels: such as plywood, blockboard, and timber, which come from formwork, scaffolding boards, and packing boxes; plastic panels: such as plastic snap-on panels and plastic mats; metal panels: such as scraps from color steel plates; and composite panels: such as aluminum composite panels.

[0003] Recycling construction waste from building materials sites is of great significance and has the following benefits: it reduces the demand for new raw materials and lowers resource consumption; it saves on waste disposal costs and the expense of purchasing new materials; and it reduces the negative environmental impact of landfill and incineration.

[0004] The current process for recycling wood-based panel waste involves: separating wood-based panel waste from other waste at the construction site, using a crushing device to break the panels into appropriate sizes, and then further processing them into recycled wood-based panels, wood chipboard, and other products, some of which can be used for biomass fuel.

[0005] However, most current board crushing equipment only crushes the boards, without treating the cement, dirt, and nails attached to them, resulting in a lot of dust at the crushing site and making subsequent secondary processing quite troublesome. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a device for crushing and processing construction waste from building construction sites, which solves the problems mentioned in the background section.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A construction waste crushing and processing device for building boards used on construction sites includes a supporting base plate. A crushing flotation component is installed on the surface of the supporting base plate, and a crushing component is installed on top of the crushing flotation component. The crushing component includes a main frame and crushing parts. Inside the main frame, from top to bottom, a roller pressing and guiding component, crushing parts, and a scraping mechanism are installed sequentially. The crushing parts include a first crushing roller and a second crushing roller, which are symmetrically slidably installed in the main frame. A central drive component that synchronously drives the opening and closing of the first and second crushing rollers is installed at the end of the main frame. The roller pressing and guiding component is installed on the top surface of the main frame. An agitation component is installed inside the crushing flotation component, and a steering and discharge component is built into the agitation component. A recovery seat is provided on one side of the crushing flotation component.

[0009] The operation of the device includes the following steps:

[0010] S1. The roller pressing and conveying assembly conveys the waste board downwards and crushes and cleans the residual cement on the surface of the waste board;

[0011] S2. Determine whether the waste board is recyclable;

[0012] Yes, enter S3;

[0013] No, proceed to S4;

[0014] S3. Board cleaning and recycling:

[0015] S3.1 Adjust the stirring component to the guiding posture and adjust the steering and exporting component to the first-level guiding posture;

[0016] S3.2 The central drive assembly drives the first crushing roller and the second crushing roller to open to form an output gap. During the opening process, the first crushing roller and the second crushing roller drive the scraping mechanism to close. The second crushing roller moves outward to drive the steering output assembly to adjust to the secondary conveying posture.

[0017] S3.3 The side of the sheet is cleaned by the scraping mechanism and then exported through the export gap;

[0018] S3.4 The sheet material is stably output to the recycling station along the steering output component;

[0019] S4. Waste board crushing and processing:

[0020] The waste plates are processed into smaller pieces by the crushing unit, and then the smaller pieces fall into the fragment flotation unit.

[0021] The agitator agitates the crushed plates within the crushed plate flotation unit to remove cement impurities and nails from the crushed plates.

[0022] Furthermore, a first movable seat is installed at both ends of the first crushing roller, and a second movable seat is installed at both ends of the second crushing roller. The first and second movable seats are symmetrically slidably positioned outside the side slide groove. The central drive assembly is fixed to the middle of the end face of the main frame, and the first and second movable seats are assembled at both ends of the central drive assembly. The central drive assembly includes a motor frame, a bidirectional screw, and a guide slide rod. The motor frame is fixed to the end face of the main frame, and a main drive motor is installed at the bottom of the motor frame. The output end of the main drive motor is engaged with the middle of the bidirectional screw. The middle parts of the bidirectional screw and the guide slide rod are both vertically fixed inside the motor frame. The guide slide rod is located above the bidirectional screw. The first and second movable seats are symmetrically slidably fitted onto the two ends of the guide slide rod, and the symmetrical threads of the first and second movable seats are fitted onto the two ends of the bidirectional screw.

[0023] Furthermore, the scraping mechanism includes a first scraping component and a second scraping component, which are arranged in a mirror-symmetrical manner. The first scraping component includes an outer plate, a connecting rod, and a shovel plate. The connecting rod slides vertically through the outer frame, with its outer end vertically connected to the outer plate and its inner end vertically connected to the shovel plate. Telescopic linkage components are installed at both ends of the outer plate.

[0024] Furthermore, the telescopic linkage assembly includes a first toothed plate, an upper plate, a central gear, and a second toothed plate. The upper plate is vertically disposed on the end face of the main frame, and a central gear is installed on the bottom surface of the end of the upper plate. The central gear is symmetrically meshed with the first toothed plate and the second toothed plate. The first toothed plate is vertically disposed on the end face of the main frame, and the second toothed plate is horizontally disposed on the surface of the first movable seat. When the first movable seat moves outward, the second toothed plate moves outward and drives the first toothed plate to move inward through the central gear.

[0025] Furthermore, the crushed plate flotation assembly includes a flotation box, a collection basket, and a liquid collection tank. The flotation box is located directly below the main frame. An agitation component is installed inside the flotation box. A collection basket is located on the other side of the flotation box away from the recovery seat. Both the collection basket and the flotation box are located on the surface of the liquid collection tank. The bottom of the collection basket has a mesh structure, and the side of the flotation box near the collection basket has a sloping structure.

[0026] Furthermore, the agitation assembly includes an agitation spindle, a magnetic rod, and an agitation plate. The agitation spindle is horizontally placed within the main frame. The outer wall of the spindle is spaced apart by the magnetic rod and the agitation plate. The side cross-sections of the magnetic rod and the agitation plate are X-shaped. A steering and guide assembly is slidably embedded at the end of the agitation plate. The magnetic rod is used to attract iron nails.

[0027] Furthermore, a contact plate is vertically installed on the bottom surface of the first crushing roller. The steering and output assembly includes a drive rod, a horizontal plate, a main output plate, and a cover plate. The drive rod is fixed inside the agitator shaft. The top end of the drive rod is vertically connected to the horizontal plate. The outer end of the horizontal plate is rotatably connected to the main output plate, and a torsion spring is installed at the rotatable connection. A cover plate is provided at the top end of the main output plate. A winding motor is installed inside the cover plate. A receiving groove is opened inside the main output plate. A T-shaped secondary output plate is slidably embedded inside the receiving groove.

[0028] Specifically, S3.1 involves the agitator rotating eccentrically 20°-45° to one side of the contact plate; the drive rod drives the main guide plate to tilt and extend outward, causing the main guide plate to move to the outside of the contact plate, thus forming a primary guiding posture.

[0029] In S3.2, when the first crushing roller moves outward, the contact plate abuts against the main output plate and rotates, causing the main output plate to tilt towards the recovery seat; the winding motor releases the traction rope, causing the secondary output plate to slide out, and the qualified plate is output along the main output plate and the secondary output plate to the recovery seat to form a secondary guiding posture.

[0030] Furthermore, the roller pressing and guiding assembly includes end plates, which are symmetrically installed on the main frame. Roller rollers are installed between the two sets of end plates, and the outer wall of the roller rollers has a frosted structure.

[0031] Furthermore, the surface of the supporting base plate is vertically provided with a vertical plate, the main frame is installed on the inner wall of the vertical plate, a spray frame is installed at the top of the inner wall of the vertical plate, the spray frame is placed above the roller, and the liquid collection tank is connected to the spray frame through a water pump.

[0032] Furthermore, a hot air blower is installed on the side of the liquid collection tank, with one output end of the hot air blower connected to the collection basket and the other output end located on the side of the recycling seat.

[0033] This invention provides a device for crushing and processing construction waste from building construction sites. Compared with the prior art, it has the following advantages:

[0034] 1. The roller pressing and guiding assembly can not only convey waste boards downwards, but also press the waste boards during the conveying process, thereby crushing the impurities on the waste boards and achieving one-time cleaning of attached cement and soil;

[0035] 2. The crushing components can shred waste boards, facilitating subsequent centralized recycling;

[0036] 3. During the crushing process, the surface of the board will be checked to see if it is intact. If it is intact and can be reused, it will only be cleaned and will not be crushed. No separate cleaning is required. If the board is not intact and cannot be recycled, it will be crushed directly.

[0037] 4. When the recyclable sheet material is output, it cannot be directly turned to the recycling station. Therefore, the turning and output component is designed to receive the recyclable sheet material, so that the sheet material will not enter the crushed flotation component, but will be tilted and output to the recycling station.

[0038] 5. The central drive assembly can drive the opening and closing of the first crushing roller and the second crushing roller, which can achieve the following effects: when conveying non-recyclable plates, the first crushing roller and the second crushing roller approach each other to achieve crushing; when conveying recyclable plates, the first crushing roller and the second crushing roller separate, so as not to affect the normal output of the plates; the posture of the steering and output assembly can be adjusted so that the steering and output assembly can normally output the recycled plates.

[0053] Example

[0054] To address the technical problems in the background art, the following embodiments are provided:

[0055] Combination Figures 1-10 As shown, the construction waste crushing and processing device for building materials used in construction sites provided by the present invention includes a supporting base plate 1. A crushed board flotation component 4 is installed on the surface of the supporting base plate 1. A crushing component 3 is installed on the top of the crushed board flotation component 4. The crushing component 3 includes a main frame 31 and crushing parts. The main frame 31 is equipped with a roller pressing and guiding component 2, crushing parts, and a scraping mechanism from top to bottom. The crushing parts include a first crushing roller 32 and a second crushing roller 35. The first crushing roller 32 and the second crushing roller 35 are symmetrically and slidably installed in the main frame 31. A middle driving component 36 that synchronously drives the opening and closing of the first crushing roller 32 and the second crushing roller 35 is installed at the end of the main frame 31. The roller pressing and guiding component 2 is installed on the top surface of the main frame 31. An agitation component 5 is installed inside the crushed board flotation component 4. The agitation component 5 has a built-in steering and discharge component 8. A recovery seat 6 is provided on one side of the crushed board flotation component 4.

[0056] The operation of the device includes the following steps:

[0057] S1. The roller pressing and guiding assembly 2 conveys the waste board downwards and crushes and cleans the residual cement on the surface of the waste board;

[0058] S2. Determine whether the waste board is recyclable;

[0059] Yes, enter S3;

[0060] No, proceed to S4;

[0061] S3. Board cleaning and recycling:

[0062] S3.1, The stirring component 5 is adjusted to the guiding posture, and the turning and exporting component 8 is adjusted to the first-level guiding posture;

[0063] S3.2, the middle drive assembly 36 drives the first crushing roller 32 and the second crushing roller 35 to open to form an output gap, and during the opening process, the first crushing roller 32 and the second crushing roller 35 drive the scraping mechanism to close; the second crushing roller 35 moves outward to drive the steering output assembly 8 to adjust to the secondary conveying posture.

[0064] S3.3 The side of the sheet is cleaned by the scraping mechanism and then exported through the export gap;

[0065] S3.4 The sheet material is stably output to the recycling seat 6 along the steering output component 8;

[0066] S4. Waste board crushing and processing:

[0067] The waste board is processed into fragments by the crushing component, and then the fragments fall into the fragment flotation assembly 4.

[0068] The agitation component 5 agitates the crushed plates in the crushed plate flotation component 4 to remove cement impurities and nails from the crushed plates.

[0069] In the above scheme:

[0070] 1. The roller pressing and guiding assembly can not only convey waste boards downwards, but also press the waste boards during the conveying process, thereby crushing the impurities on the waste boards and achieving one-time cleaning of attached cement and soil;

[0071] 2. The crushing components can shred waste boards, facilitating subsequent centralized recycling;

[0072] 3. During the crushing process, the surface of the board will be checked to see if it is intact. If it is intact and can be reused, it will only be cleaned and not crushed. If the board is not intact and cannot be recycled, it will be crushed directly.

[0073] 4. When the recyclable sheet material is output, it cannot be directly turned to the recycling station. Therefore, the turning and output component is designed to receive the recyclable sheet material, so that the sheet material will not enter the crushed flotation component, but will be tilted and output to the recycling station.

[0074] 5. The central drive assembly can drive the opening and closing of the first and second crushing rollers, achieving the following effects:

[0075] 5.1 When conveying unrecoverable sheet metal, the first and second crushing rollers move close together to achieve crushing.

[0076] 5.2 When conveying recyclable sheet materials, the first crushing roller and the second crushing roller are separated, so as not to affect the normal output of the sheet materials;

[0077] 5.3 The attitude of the steering and exporting component can be adjusted so that the steering and exporting component can properly export and recycle the sheet material.

[0078] In this embodiment, first movable seats 321 are installed at both ends of the first crushing roller 32, and second movable seats 351 are installed at both ends of the second crushing roller 35. The first movable seats 321 and the second movable seats 351 are symmetrically slidably placed outside the side slide groove 311. The middle drive assembly 36 is fixed to the middle of the end face of the main frame 31, and the first movable seats 321 and the second movable seats 351 are assembled at both ends of the middle drive assembly 36. The middle drive assembly 36 includes a motor frame 361, a bidirectional screw 363, and a guide slide rod 364. The main drive motor 362 is installed at the bottom of the motor frame 361, which is fixed to the end face of the main frame 31. The output end of the main drive motor 362 is engaged with the middle part of the bidirectional screw 363. The middle parts of the bidirectional screw 363 and the guide slide rod 364 are both vertically fixed inside the motor frame 361. The guide slide rod 364 is located above the bidirectional screw 363. The first moving seat 321 and the second moving seat 351 are symmetrically slidably fitted at both ends of the guide slide rod 364. The symmetrical threads of the first moving seat 321 and the second moving seat 351 are fitted at both ends of the bidirectional screw 363.

[0079] In the above scheme, the main drive motor drives the bidirectional screw to rotate, the bidirectional screw drives the first moving seat and the second moving seat to move outward, the guide slide rod can guide the movement process, and when the first moving seat and the second moving seat move outward, they drive the corresponding first crushing roller and the second crushing roller to move outward.

[0080] In this embodiment, the scraping mechanism includes a first scraping component 33 and a second scraping component 34. The first scraping component 33 and the second scraping component 34 are arranged in a mirror-symmetrical manner. The first scraping component 33 includes an outer plate 331, a connecting rod 336, and a scraper plate 337. The connecting rod 336 slides vertically through the outer frame. The outer end of the connecting rod 336 is vertically connected to the outer plate 331, and the inner end of the connecting rod 336 is vertically connected to the scraper plate 337. Telescopic linkage components are installed at both ends of the outer plate 331.

[0081] In the above scheme, the roller-pressed plate will first pass through two sets of scraping components, and the scraper can remove the still attached cement particles to achieve secondary cleaning.

[0082] In this embodiment, the telescopic linkage assembly includes a first toothed plate 332, an upper plate 333, a central gear 334, and a second toothed plate 335. The upper plate 333 is vertically disposed on the end face of the main frame 31. The central gear 334 is installed on the bottom end of the upper plate 333. The central gear 334 is symmetrically meshed with the first toothed plate 332 and the second toothed plate 335. The first toothed plate 332 is vertically disposed on the end face of the main frame 31, and the second toothed plate 335 is horizontally disposed on the surface of the first movable seat 321. When the first movable seat 321 moves outward, the second toothed plate 335 moves outward and drives the first toothed plate 332 to move inward through the central gear 334.

[0083] In the above scheme, the design of the transfer gear can realize translational linkage, so that when the first moving seat moves outward, the first toothed plate moves inward, and when the two moving seats move away from each other, the first scraping assembly and the second scraping assembly will move closer.

[0084] In this embodiment, the crushed plate flotation assembly 4 includes a flotation box 41, a collection basket 42, and a liquid collection tank 43. The flotation box 41 is located directly below the main frame 31. An agitation assembly 5 is installed inside the flotation box 41. The collection basket 42 is located on the other side of the flotation box 41 away from the recovery seat 6. Both the collection basket 42 and the flotation box 41 are located on the surface of the liquid collection tank 43. The bottom of the collection basket 42 has a mesh structure, and the side of the flotation box 41 near the collection basket 42 has a sloping structure.

[0085] In the above scheme, the flotation tank stores water, which can use buoyancy to keep the crushed plates always at the top and prevent them from sinking. During the agitation process, the crushed plates can be discharged to the collection basket, while cement and iron will sink into the water, achieving efficient separation. The water and impurities in the collection basket will also fall into the liquid collection tank through the mesh structure.

[0086] In this embodiment, the stirring assembly 5 includes a stirring spindle 51, a magnetic rod 52, and a stirring plate 53. The spindle is horizontally placed inside the main frame 31. The magnetic rod 52 and the stirring plate 53 are spaced apart on the outer wall axis of the stirring spindle. The side cross-sections of the magnetic rod 52 and the stirring plate 53 are X-shaped. A steering and guiding assembly 8 is slidably embedded at the end of the stirring plate 53. The magnetic rod 52 is used to attract iron nails.

[0087] In the above scheme, the stirring component can quickly push out the broken plates floating on the surface when stirring, and the iron nails will be attracted to the magnetic rod.

[0088] In this embodiment, a contact plate 322 is vertically mounted on the bottom surface of the first crushing roller 32. The steering and output assembly 8 includes a drive rod 81, a horizontal plate 82, a main output plate 83, and a cover plate 84. The drive rod 81 is fixed inside the stirring main shaft 51. The top end of the drive rod 81 is vertically connected to the horizontal plate 82. The outer end of the horizontal plate 82 is rotatably connected to the main output plate 83, and a torsion spring is installed at the rotatable connection. The top end of the main output plate 83 is provided with a cover plate 84. A winding motor 87 is installed inside the cover plate 84. A receiving groove 831 is opened inside the main output plate 83. A T-shaped secondary output plate 86 is slidably embedded inside the receiving groove 831.

[0089] Specifically, in S3.1, the stirring plate 53 rotates eccentrically 20°-45° to one side of the contact plate 322; the driving rod 81 drives the main guide plate 83 to tilt and extend outward, so that the main guide plate 83 moves outward to the outside of the contact plate 322 to form a primary guiding posture.

[0090] In S3.2, when the first crushing roller 32 moves outward, the contact plate 322 abuts against the main output plate 83 and rotates, causing the main output plate 83 to tilt towards the recovery seat 6; the winding motor 87 releases the traction rope 85, causing the secondary output plate 86 to slide out, and the qualified plate is output along the main output plate 83 and the secondary output plate 86 to the recovery seat 6 to form a secondary guiding posture.

[0091] In the above scheme, when outputting broken plates, the turning and output component is received into the stirring plate, thereby ensuring that the overall shape of the stirring plate is regular and the broken plates can be output normally.

[0092] When outputting the recyclable plate, first adjust it to the primary guiding posture so that the main output plate extends out and is located outside the contact plate, in preparation for subsequent rotation and adjustment;

[0093] Subsequently, when the moving seat moves outward, the contact plate can abut against the main ejector plate, causing the main ejector plate to be adjusted to an inclined state facing the recycling seat, thereby realizing the ejection of the sheet material;

[0094] Since the length of the main output plate is limited and there will be gaps during output, a secondary output plate was designed. When the winding motor releases the traction rope, the secondary output plate can slide out under its own weight. The T-shaped design can stop and position when it moves down to the bottom. When it is subsequently retracted, the winding motor winds up the traction rope, so that the secondary output plate is stored in the main output plate.

[0095] In this embodiment, the roller pressing and guiding assembly 2 includes end plates 21, which are symmetrically mounted on the main frame 31. Roller rollers 22 are installed between the two sets of end plates 21, and the outer wall of the roller rollers 22 has a frosted structure.

[0096] In this embodiment, a vertical plate 11 is vertically provided on the surface of the supporting base plate 1, the main frame 31 is installed on the inner wall of the vertical plate 11, a spray rack 111 is installed at the top of the inner wall of the vertical plate 11, the spray rack 111 is placed above the roller 22, and the liquid collection tank 43 is connected to the spray rack 111 through a water pump 44.

[0097] In the above solution, the sprayer can spray mist to reduce dust and improve the environment of the feeding area.

[0098] In this embodiment, a hot air blower 7 is installed on the side of the liquid collection tank 43. One output end of the hot air blower 7 is connected to the collection basket 42, and the other output end is located on the side of the recycling seat 6.

[0099] In the above scheme, the hot air blower can output hot air to dry the broken boards in the collection basket and the good boards on the recycling seat.
