Description

Technical Field

[0001] This invention relates to the field of construction waste treatment technology, specifically to a device for treating construction waste from civil engineering buildings. Background Technology

[0002] During the construction of civil engineering buildings, a large amount of construction waste, including concrete blocks, bricks, and steel rebar fragments, is generated. If this waste is directly piled up or discarded without proper treatment, it will not only occupy a large amount of land resources, but may also cause a series of problems such as environmental pollution and resource waste. Therefore, the efficient treatment and resource recycling of construction waste has become a key focus of the industry.

[0003] Currently, construction waste treatment equipment has been widely used in the engineering field. Its core functions usually include crushing, sorting and environmental treatment of waste, aiming to reduce, harmlessly treat and recycle waste through mechanized means. Existing construction waste processing devices are generally equipped with crushing rollers to pulverize large pieces of waste. However, in actual operation, due to the complex composition and irregular shape of the waste, it is easy for it to accumulate and clog at the feed channel of the crushing roller, leading to equipment shutdown for cleaning. This seriously affects the continuity of crushing operations and overall processing efficiency. At the same time, the steel bars and other metals contained in the waste have high recycling value, but the metal sorting function of existing processing devices is often inadequate, relying mostly on manual sorting or a single magnetic suction structure. This results in defects such as low sorting accuracy, insufficient metal recovery rate, high labor costs, and cumbersome sorting processes, making it difficult to achieve efficient and automated separation and collection of metals. In addition, a large amount of dust is generated during the crushing operation. This dust not only pollutes the surrounding air environment but also harms the health of operators. Existing dust suppression methods often require additional equipment such as high-pressure sprayers, which not only increases the manufacturing cost and operating energy consumption of the device but also has problems such as the timing of dust suppression not synchronizing with the crushing operation and poor dust suppression effect, making it difficult to meet the actual needs of environmental protection operations. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a civil engineering building construction waste treatment device, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a civil engineering construction waste processing device, comprising a frame, wherein two crushing rollers with intermittently fitted outer surfaces are rotatably mounted on the inner side of the frame, the crushing rollers being powered by a drive motor for crushing construction waste; a mounting frame is fixedly connected to the top center of the frame, and a connecting shaft is movably connected inside the mounting frame via bearings; multiple evenly distributed rotating parts are rotatably sleeved on the outside of the connecting shaft, and a connecting part is hinged to the inner side of each rotating part; a fixing plate is installed at the bottom end of the connecting part, and several straight-lined clearing teeth are fixedly connected to the outer side of the fixing plate; and a bevel gear is fixedly connected to one end of the connecting shaft. A mounting box is detachably connected to one side of the mounting bracket. A rotating shaft is movably mounted inside the mounting box via bearings. A spline shaft is keyed to the outside of the rotating shaft, and a spline sleeve is slidably fitted onto the outside of the spline shaft. A screw is rotatably mounted inside the mounting box, and a threaded plate is threaded to the outside of the screw. A bevel gear one, which is compatible with bevel gear two, is fixedly connected to the outside of the spline sleeve. The rotation of the screw drives the threaded plate to translate axially, thereby driving the spline sleeve and bevel gear one to move synchronously until bevel gear one and bevel gear two precisely mesh, so that the connecting shaft obtains rotational power. With the hinge structure of the rotating part and the connecting part, the unblocking teeth are driven to perform a high-frequency reciprocating unblocking action, realizing the anti-clogging function of the crushing roller feed channel.

Both drive racks and sector gears form a meshing transmission structure. One end of the movable seat is fixedly connected to a movable plate through a connecting rod. The movable plate is arranged at a preset inclination angle. Through the alternating meshing of the sector gear and the drive rack, the movable seat is driven to perform reciprocating linear motion, thereby driving the movable plate to achieve high-frequency vibration.

[0008] Preferably, a reciprocating screw is movably connected to the inner side of the processing box via a bearing, and a movable seat is threaded onto the outer side of the reciprocating screw. An electromagnet roller is installed at the bottom of the movable seat, and a motor for driving the reciprocating screw is installed on the outer side of the processing box. A storage box one is detachably connected to one side of the processing box, and a storage box two is detachably connected to the side of the processing box away from the storage box one. The reciprocating screw is rotated by a servo motor, causing the movable seat to reciprocate at a uniform speed along the axis of the reciprocating screw. The strong magnetic adsorption characteristics of the electromagnet roller are used to achieve precise separation of metal impurities in the waste. When the movable seat moves above the metal storage box one, the directional release and collection of metal impurities are achieved through magnetic adjustment.

[0009] Preferably, both the mounting shaft and the rotating shaft are fixedly connected to a bevel gear three at their ends, and the outer sides of the two bevel gear three are meshed together.

[0010] Preferably, a rotating disk is fixedly connected to the end of one of the crushing rollers. A driving block is fixedly connected to the eccentric part of the rotating disk. A movable frame is slidably connected to the outer surface of the rotating disk. A fixing component is fixedly connected to the outer side of the movable frame.

A storage box is fixedly connected to one side of the frame. A spray pipe is connected to one end of the connecting pipe two. Multiple atomizing nozzles are installed on the outer surface of the spray pipe. The rotating disk drives the driving block to rotate eccentrically, which drives the movable frame and the fixing component to reciprocate linearly. This, in turn, drives the rubber piston at the end of the movable cylinder to slide back and forth at high frequency along the inside of the fixed cylinder. Through the periodic change of air pressure inside the fixed cylinder, the dust-suppressing liquid in the storage box is sprayed out as micron-sized droplets through the high-pressure atomizing nozzles, achieving efficient dust reduction during the crushing process.

[0011] Preferably, both the first connecting pipe and the second connecting pipe are equipped with a one-way valve inside, the two one-way valves have opposite conduction directions, and the end of the first connecting pipe away from the fixed cylinder is connected to the interior of the storage box.

[0013] Preferably, two symmetrically arranged guide ramps are fixedly connected to the lower side of the inside of the frame. The guide ramps are arranged at a preset angle to guide the crushed waste material to fall accurately into the inside of the mounting cylinder.

[0014] This invention provides a device for treating construction waste from civil engineering buildings. It has the following beneficial effects: 1. This invention optimizes the anti-blocking structure design of the feeding channel, enabling efficient operation of the unblocking function during the crushing of construction waste. The high-frequency reciprocating unblocking action can promptly break up the accumulation and blockage of waste in the feeding area of ​​the crushing roller, effectively avoiding equipment downtime and reduced crushing efficiency caused by material jamming. This significantly improves the continuity and stability of waste processing, while simplifying the power transmission path of the anti-blocking mechanism, reducing equipment operating energy consumption and maintenance costs, extending the overall service life of the device, and adapting to the crushing and processing needs of various civil engineering and building construction waste.

[0015] 2. This invention achieves efficient screening and automated collection of metal materials in construction waste through the coordinated reciprocating movement of the movable plate and the reciprocating movement of the electromagnet roller. This effectively improves the accuracy and comprehensiveness of metal impurity separation, avoids the waste of metal resources, and completes the directional transfer of metal materials to the storage box without manual intervention, which greatly reduces labor costs, improves the overall efficiency of waste treatment, and simplifies the waste sorting process.

[0016] 3. During the crushing operation of construction waste by the crushing roller, the present invention can simultaneously drive the movable cylinder to reciprocate along the inside of the fixed cylinder. By changing the air pressure, water in the storage tank is sprayed out through the spray pipe to suppress dust. There is no need to configure additional special dust suppression power equipment, which effectively simplifies the overall structure of the device, reduces the manufacturing cost and operating energy consumption of the equipment, significantly improves the air quality of the working environment, and reduces the impact of dust pollution on the health of operators and the surrounding environment.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see the appendix Figure 1 - Appendix Figure 11This invention provides a civil engineering construction waste treatment device, including a frame 1. Two crushing rollers 3 with intermittently fitted outer surfaces are rotatably mounted inside the frame 1. The crushing rollers 3 are powered by a drive motor and used to crush construction waste. A mounting frame 2 is fixedly connected to the top center of the frame 1. A connecting shaft 52 is movably connected inside the mounting frame 2 via bearings. Multiple evenly distributed rotating parts 54 are rotatably sleeved on the outside of the connecting shaft 52. Each rotating part 54 has a connecting part 55 hinged to its inner side. A fixing plate 53 is installed at the bottom of the connecting part 55. Several straight-lined clearing teeth 51 are fixedly connected to the outside of the fixing plate 53. A bevel gear 65 is fixedly connected to one end of the connecting shaft 52. A mounting box 6 is detachably connected to one side of the mounting frame 2. 1. Inside the mounting box 61, a rotating shaft 66 is movably mounted via bearings. A splined shaft 62 is keyed to the outside of the rotating shaft 66. A splined sleeve 63 is slidably fitted onto the outside of the splined shaft 62. A screw is rotatably mounted inside the mounting box 61, and a threaded plate 67 is threadedly connected to the outside of the screw. A bevel gear 64, compatible with bevel gear 65, is fixedly connected to the outside of the splined sleeve 63. The rotation of the screw drives the threaded plate 67 to translate axially, thereby causing the splined sleeve 63 and bevel gear 64 to move synchronously until bevel gear 64 and bevel gear 65 precisely mesh, giving the connecting shaft 52 rotational power. Combined with the hinged structure of the rotating component 54 and the connecting component 55, this drives the unblocking gear 51 to perform a high-frequency reciprocating unblocking action, achieving the anti-clogging function of the feed channel of the crushing roller 3. The splined sleeve 63 and the threaded plate 67 are movably connected via bearings.

[0021] Specifically, the feeding channel is cleared through precise switching of power transmission and efficient conversion of motion. The power output from the drive motor is transmitted to the splined shaft 62 via the rotating shaft 66. When the feeding channel of the crushing roller 3 is blocked by waste material, the screw inside the rotating mounting box 61 is rotated, and the threaded plate 67 is driven to move smoothly along the axial direction by the threaded transmission. Since the splined sleeve 63 and the threaded plate 67 are connected by a bearing, the threaded plate 67 synchronously drives the splined sleeve 63 to slide along the splined shaft 62, so that the bevel gear 64 on the outer side of the splined sleeve 63 engages with the connecting... The bevel gear 65 at one end of shaft 52 meshes precisely, thereby transmitting the rotational power of rotating shaft 66 to connecting shaft 52. When connecting shaft 52 rotates, it drives the evenly distributed rotating parts 54 on the outside to rotate synchronously. With the help of the hinged cooperation between rotating parts 54 and connecting parts 55, the rotational motion is converted into the high-frequency reciprocating linear motion of fixed plate 53. Finally, it drives the unblocking teeth 51 on the outside of fixed plate 53 to reciprocate and guide the congested waste in the feed channel of crushing roller 3, quickly breaking up the accumulated blockage and ensuring the continuity of feeding and crushing operations.

[0022] A processing box 4 is fixedly connected to the bottom of the frame 1. An inclined movable plate 9 is provided inside the processing box 4. An installation cylinder 81 is fixedly connected inside the processing box 4. Two symmetrically arranged feeding grooves 82 are opened on the outer surface of the installation cylinder 81. A drive motor is installed on the outside of the processing box 4. An installation shaft 83 is fixedly connected to the output end of the drive motor. Multiple feeding plates 84 are fixedly connected at equal angles to the outside of the installation shaft 83. The crushed waste material falls precisely into the receiving cavity between the feeding plates 84 through the feeding grooves 82. The waste material is evenly distributed to the upper surface of the movable plate 9 by the rotation of the feeding plates 84.

[0023] Specifically, the orderly and uniform distribution of waste is achieved through the coordinated cooperation of material guidance and power drive. After being crushed, the waste is conveyed to the installation cylinder 81 area by the guide structure. Then, it is precisely entered into the receiving cavity between the feeding plates 84 through the two symmetrical feeding grooves 82 on the outer surface of the installation cylinder 81. The drive motor on the outside of the processing box 4 outputs power to drive the installation shaft 83 to rotate. The installation shaft 83 synchronously drives multiple feeding plates 84 distributed at equal angles on the outside to make circular motion. The rotational thrust of the feeding plates 84 is used to continuously and evenly push the waste in the receiving cavity to the upper surface of the inclined movable plate 9, avoiding the local accumulation of waste on the movable plate 9. This provides a uniform material distribution basis for subsequent metal sorting and other processes, ensuring the stability and efficiency of subsequent processing operations.

[0024] A mounting base 71 is fixedly connected to the inner wall of the processing box 4. A movable seat 72 is slidably embedded inside the mounting base 71. A drive rack 75 is fixedly connected to both the upper and lower sides of the movable seat 72. A sector gear 74 is coaxially fixedly connected to one side of the mounting shaft 83. Both drive racks 75 and sector gears 74 form a meshing transmission structure. One end of the movable seat 72 is fixedly connected to the movable plate 9 through a connecting rod 73. The movable plate 9 is arranged at a preset angle. Through the alternating meshing of sector gears 74 and drive racks 75, the movable seat 72 is driven to perform reciprocating linear motion, thereby driving the movable plate 9 to achieve high-frequency vibration. Bevel gears 68 are fixedly connected to the ends of the mounting shaft 83 and the rotating shaft 66. The outer sides of the two bevel gears 68 are meshed.

[0025] Specifically, the transformation of motion and efficient transmission of power are achieved through gear meshing. When the mounting shaft 83 rotates, it synchronously drives the coaxial sector gear 74 to rotate. Utilizing the alternating meshing characteristics of the sector gear 74 and the drive racks 75 on the upper and lower sides inside the movable seat 72, the rotational motion of the sector gear 74 is converted into the reciprocating linear motion of the movable seat 72 along the mounting seat 71. The movable seat 72 transmits the reciprocating power to the inclined movable plate 9 through the connecting rod 73, causing the movable plate 9 to generate high-frequency vibration. This can both accelerate the conveying of waste on the movable plate 9 and break up the accumulated waste, laying a foundation for uniform material distribution in subsequent sorting operations. At the same time, the bevel gear 68 at the end of the mounting shaft 83 meshes with the bevel gear 68 at the end of the rotating shaft 66, realizing the synchronous linkage of multiple mechanisms and improving the overall coordination and energy efficiency of the device.

[0026] A reciprocating screw 22 is movably connected to the inner side of the processing box 4 via a bearing. A movable seat 23 is threadedly connected to the outer side of the reciprocating screw 22. An electromagnet roller 24 is installed at the bottom of the movable seat 23. A motor for driving the reciprocating screw 22 is installed on the outer side of the processing box 4. A storage box 11 is detachably connected to one side of the processing box 4. A storage box 22 is detachably connected to the side of the processing box 4 away from the storage box 11. The reciprocating screw 22 is driven to rotate by a servo motor, which drives the movable seat 23 to reciprocate at a uniform speed along the axis of the reciprocating screw 22. The strong magnetic adsorption characteristics of the electromagnet roller 24 are used to achieve precise separation of metal impurities in the waste. When the movable seat 23 is moved above the metal storage box 11, the directional release and collection of metal impurities are achieved through magnetic adjustment.

[0027] Specifically, the rotational power output by the servo motor is transmitted to the reciprocating screw 22, which drives the movable seat 23, which is threadedly connected to the reciprocating screw 22, to reciprocate at a constant speed along the axis. When the electromagnet roller 24 at the bottom of the movable seat 23 is energized, it generates a strong magnetic attraction force, which fully adsorbs the metal impurities in the waste in the processing box 4 during the reciprocating movement. When the movable seat 23 is precisely positioned above the storage box 11, the electromagnet roller 24 is demagnetized by adjusting the magnetic intensity. The metal impurities fall into the storage box 11 under the action of gravity and are collected. The non-metallic waste slides down the preset path to the storage box 22, realizing the precise separation and classified storage of metal and non-metallic waste, and improving the efficiency of waste resource recycling.

[0028] One of the crushing rollers 3 is fixedly connected to a rotating disk 16 at its end. A drive block 17 is fixedly connected to the eccentric part of the rotating disk 16. A movable frame 25 is slidably connected to the outer surface of the rotating disk 16. A fixing member 15 is fixedly connected to the outer side of the movable frame 25. A fixed cylinder 13 is fixedly connected to the outer side of the frame 1. A rubber piston is slidably connected to the inside of the fixed cylinder 13. A movable cylinder 14 is fixedly connected to the outside of the rubber piston. A connecting pipe 20 and a connecting pipe 21 are sequentially connected to the outer surface of the fixed cylinder 13. A storage device is fixedly connected to one side of the frame 1. The storage tank 19 has a spray pipe 18 connected to one end of the connecting pipe 21. Multiple atomizing nozzles are mounted on the outer surface of the spray pipe 18. The rotating disk 16 drives the drive block 17 to rotate eccentrically, which in turn drives the movable frame 25 and the fixed component 15 to reciprocate linearly. This, in turn, causes the rubber piston at the end of the movable cylinder 14 to slide back and forth along the inside of the fixed cylinder 13 at high frequency. Through the periodic changes in air pressure inside the fixed cylinder 13, the dust-suppressing liquid in the storage tank 19 is sprayed out as micron-sized droplets through the high-pressure atomizing nozzles, achieving efficient dust reduction during the crushing process. Both the connecting pipe 20 and the connecting pipe 21 have one-way valves installed inside, with opposite directions of operation. The end of the connecting pipe 20 furthest from the fixed cylinder 13 is connected to the inside of the storage tank 19. The movable frame 25 has an internal groove adapted to the drive block 17, which is slidably embedded within the groove.

[0029] Specifically, the dust suppression liquid is synchronously atomized and sprayed through power linkage and air pressure drive. When the crushing roller 3 rotates, it synchronously drives the rotating disk 16 at the end to rotate, causing the drive block 17 at the eccentric position outside the rotating disk 16 to perform eccentric rotational motion. By utilizing the sliding cooperation between the drive block 17 and the movable groove inside the movable frame 25, the rotational motion is converted into the reciprocating linear motion of the movable frame 25 and the fixed part 15. The fixed part 15 drives the movable cylinder 14 to move synchronously, causing the rubber piston at the end of the movable cylinder 14 to slide back and forth at high frequency along the sealed inside of the fixed cylinder 13, thereby generating periodic air pressure changes inside the fixed cylinder 13. With the cooperation of the air pressure difference and the reverse one-way valves inside the connecting pipe 1 20 and the connecting pipe 2 21, the dust suppression liquid in the storage tank 19 is stably sucked in and pushed to the spray pipe 18. Finally, it is sprayed out as micron-level droplets through multiple atomizing nozzles on the outer surface of the spray pipe 18, realizing the synchronous linkage between crushing operation and dust suppression action, and effectively suppressing dust diffusion.

[0030] Two symmetrically arranged guide plates 10 are fixedly connected to the lower side of the inside of the frame 1. The guide plates 10 are arranged at a preset angle to guide the crushed waste material to fall accurately into the inside of the mounting cylinder 81.

[0031] Working principle: First, the device is started, and construction waste from civil engineering is fed between two crushing rollers 3 inside the frame 1. The drive motor provides power to the crushing rollers 3, and the large pieces of waste are crushed through the intermittent rotation of the two crushing rollers 3. Under its own gravity, the crushed waste is guided by two symmetrical guide plates 10 on the lower side of the frame 1 and falls precisely into the mounting cylinder 81 inside the processing box 4. Then, it enters the receiving cavity between the feeding plates 84 through the feeding groove 82 on the outer surface of the mounting cylinder 81. At this time, the drive motor on the outside of the processing box 4 starts, driving the mounting shaft 83 to rotate, which in turn drives multiple feeding plates 84 distributed at equal angles to rotate synchronously, evenly distributing the waste onto the upper surface of the inclined movable plate 9. As the mounting shaft 83 rotates, the sector gear 74 on its outer side rotates synchronously. Because the sector gear 74 alternately meshes with the drive racks 75 on the upper and lower sides inside the movable seat 72, it drives the movable seat 72 to reciprocate linearly along the interior of the mounting seat 71. The movable seat 72 drives the movable plate 9 to achieve high-frequency vibration through the connecting rod 73. This accelerates the conveying of waste material on the movable plate 9 and spreads out the accumulated waste material, providing a uniform material base for subsequent metal sorting. Simultaneously, the bevel gear 68 at the end of the mounting shaft 83 meshes with the bevel gear 68 at the end of the rotating shaft 66, providing power support for the anti-clogging mechanism. When the waste material is laid flat and conveyed on the movable plate 9, the motor driving the reciprocating screw 22 on the outside of the processing box 4 starts, causing the reciprocating screw 22 to rotate, which in turn drives the threaded movable seat 23 to reciprocate at a constant speed along the axis of the reciprocating screw 22. The electromagnet roller 24 at the bottom of the movable seat 23 is energized to generate a strong magnetic attraction force, which fully adsorbs the metal impurities in the waste material during the reciprocating movement. When the movable seat 23 moves above the storage box 11, the electromagnet roller 24 is de-energized and demagnetized by adjusting the magnetic intensity. The metal impurities fall into the storage box 11 under the action of gravity and are collected. The non-metallic waste continues to slide down the movable plate 9 into the storage box 22, realizing the efficient separation of metal and non-metallic waste. Throughout the crushing operation of the crushing roller 3, the end of one of the crushing rollers 3 drives the rotating disk 16 to rotate coaxially, and the drive block 17 at the eccentric position outside the rotating disk 16 rotates eccentrically accordingly. Since the drive block 17 is slidably embedded in the movable groove of the movable frame 25, it drives the movable frame 25 and the outer fixing part 15 to perform reciprocating linear motion. The fixing part 15 drives the movable cylinder 14 to move synchronously, so that the rubber piston at the end of the movable cylinder 14 slides along the inside of the fixed cylinder 13 in a sealed manner. Through the high-frequency reciprocating sliding of the rubber piston, the air pressure inside the fixed cylinder 13 is changed. Under the action of the air pressure difference, the dust suppression liquid in the storage tank 19 enters the fixed cylinder 13 through the connecting pipe 1 20, and is then transported to the spray pipe 18 through the connecting pipe 21. Finally, it is sprayed out by multiple atomizing nozzles on the outer surface of the spray pipe 18 to form micron-level droplets, achieving efficient dust suppression throughout the crushing operation. The one-way valves inside the connecting pipe 1 20 and the connecting pipe 2 21 have opposite conduction directions to ensure stable one-way delivery of the dust suppression liquid. If waste material accumulates and gets stuck in the feed channel of the crushing roller 3 during the crushing operation, the screw inside the mounting box 61 can be rotated to drive the threaded plate 67 to move axially, thereby causing the spline sleeve 63 to slide along the spline shaft 62. This allows the bevel gear 64 on the outside of the spline sleeve 63 to precisely mesh with the bevel gear 65 at one end of the connecting shaft 52. At this time, the rotational power of the rotating shaft 66 is transmitted to the connecting shaft 52 through the spline shaft 62, the spline sleeve 63, and the bevel gear meshing structure. The rotation of the connecting shaft 52 drives the evenly distributed rotating parts 54 to rotate synchronously. The rotating parts 54, through the hinged engagement with the connecting parts 55, drive the fixed plate 53 and the outer unblocking teeth 51 to perform a high-frequency reciprocating unblocking action, promptly breaking up the waste material blockage in the feed channel, avoiding equipment downtime, and ensuring the continuity of the crushing operation. After the jamming problem is resolved, rotating the screw in the opposite direction will disengage the bevel gear 64 and the bevel gear 65, stopping the unblocking action.

[0032] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
