Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering equipment, and in particular to a solid waste treatment device and a treatment method thereof used in construction engineering. Background Art

[0002] Solid waste refers to solid and semi-solid waste materials generated by humans in production, consumption, life and other activities. In layman's terms, it is "garbage". In the process of construction projects, a large amount of solid waste will be generated, such as concrete, bricks, etc. In order to reduce the waste of solid waste, it is generally necessary to crush these solid wastes through crushing equipment for easy recycling and reuse.

[0003] For example, in the Chinese patent with application number 202121463302.4, a waste treatment device for civil engineering construction is provided. Through the action of the set crushing roller, the incoming waste can be preliminarily crushed and the mixed plastic products and metal products inside can be cut into smaller parts.

[0004] However, since the surface temperature of the crushing roller will increase during the long crushing process, coolant is needed to dissipate the heat of the crushing roller. During the use of this type of processing device, a large amount of dust and impurities will adhere to the surface of the crushing roller during crushing. This will result in the formation of an insulating layer of dust and impurities covering the surface of the crushing roller during cooling, which will hinder the effective transfer of the coolant. In addition, the surface impurities will affect the flow of the coolant on the roller surface, making it impossible for the coolant to be evenly distributed or flowed. This uneven coolant flow will result in poor cooling effect in certain areas, thereby increasing the risk of local overheating of the roller surface.

[0005] To this end, we propose a solid waste treatment equipment and a treatment method for construction engineering. Summary of the invention

[0015] A method for treating solid waste in construction projects, mainly comprising the following steps: Step A: The solid waste generated during the construction process is placed in the lower hopper, and the baffle is driven by the cylinder 1 to slide backward in the lower hopper, and the solid waste falls onto the crushing roller, and the crushing roller is driven by the motor to rotate to crush the solid waste. When dissipating heat, the U-shaped frame and the crushing roller are driven to move to both sides by the cylinder 2, and the coolant in the storage barrel is pumped into the nozzle through the pipe and the hose 1 by starting the liquid pump, and then sprayed from the nozzle to the surface of the crushing roller for cooling. After cooling, the crushing roller is driven to reset by the cylinder 2, and the crushing operation is performed again; Step B: By setting a rectangular shell and a brush between the crushing roller and the nozzle, when the crushing roller moves to the position of the nozzle, the crushing roller will contact the brush, and some impurities and dust adhering to the surface of the crushing roller will be scraped off through the contact between the crushing roller and the brush.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. Through the setting of the scraping mechanism, before the crushing roller is moved to the position of the nozzle for cooling, some impurities and dust adhering to the surface of the crushing roller can be scraped off through the contact between the crushing roller and the brush, so as to avoid the dust and impurities covering the roller from forming a heat insulation layer, which hinders the effective transmission of the coolant, and also avoids the surface impurities from affecting the flow of the coolant on the roller surface, so that the coolant cannot be evenly distributed or flowed, resulting in poor cooling effect in some areas, thereby increasing the risk of local overheating of the roller surface. Through the setting of the scraping mechanism, by blowing air to the surface of the crushing roller, the dust and impurities can be blown off through the cooperation between the flow of the airflow and the brush, so as to avoid the scraped dust and impurities remaining on the surface of the crushing roller, thereby improving the removal effect, and through the blowing of the airflow, the dust and impurities adhering to the surface of the brush can also be blown off, so as to avoid the dust and impurities re-covering when the brush scrapes off the dust and impurities in other parts of the crushing roller.

[0017] 2. Through the setting of the auxiliary mechanism, when the scraping mechanism blows air to the surface of the crushing roller, it can also synchronously impact the U-shaped frame, so that the crushing roller vibrates. Through vibration, dust and impurities with low adhesion can be removed more cleanly, and dust and impurities with strong adhesion can be loosened more easily, making it easier for the brush to scrape off, thereby improving the removal effect.

[0018] 3. Through the setting of the adjustment mechanism and the adjustment part, while the auxiliary mechanism impacts the crushing roller, the air outlet of the nozzle can also be synchronously and intermittently reduced. When the diameter of the air outlet is reduced, the flow rate of the gas passing through will increase, thereby increasing the intensity and impact force of the gas release, and improving the removal effect of the scraping mechanism. It can also synchronously drive the rectangular shell and the brush to rotate intermittently, increase the friction between the brush and the crushing roller, and further improve the removal effect of the scraping mechanism. At the same time, through the setting of the adjustment mechanism, the airbag can also be intermittently expanded, and the expansion of the airbag generates a driving force on the brush, making it easier to remove dust and impurities adhering to the brush, and again avoiding the dust and impurities from being re-covered when the brush scrapes off dust and impurities in other parts of the crushing roller, thereby further improving the removal effect.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] Embodiment 1, refer to Figure 1-Figure 9A solid waste treatment equipment for construction engineering, comprising a frame 1, a crushing box 10 is fixed on the frame 1, a lower hopper 11 is connected to the crushing box 10, a baffle 12 is slidably arranged in the lower hopper 11, a cylinder 13 for driving the baffle 12 to move is installed on the crushing box 10, a U-shaped frame 14 is arranged in the crushing box 10, a crushing roller 15 is rotated in the U-shaped frame 14 through a bearing, a motor for driving the crushing roller 15 to rotate is installed on the U-shaped frame 14, a cylinder 2 16 for driving the U-shaped frame 14 to move is installed on the crushing box 10, and further comprising: A cooling mechanism 2 is arranged on the frame 1, and the cooling mechanism 2 is used to cool the crushing roller 15; The scraping mechanism 3 installed on the crushing box 10 is used to remove dust on the surface of the crushing roller 15 before the crushing roller 15 is cooled down.

[0023] Furthermore, the cooling mechanism 2 includes a liquid pump 21 fixed on the frame 1, a storage bucket 22 is also fixed on the frame 1, and nozzles 23 are fixed on both side walls of the crushing box 10. The liquid outlet end of the liquid pump 21 is connected to the two nozzles 23 through a hose 24, and the liquid inlet end of the liquid pump 21 is connected to the storage bucket 22 through a pipeline.

[0024] Furthermore, the scraping mechanism 3 includes a rotating shaft 31 rotatably connected to the two side walls of the crushing box 10 through bearings, a rectangular shell 32 is fixed between the two rotating shafts 31, a brush 33 is fixed to the bottom of the rectangular shell 32, a mounting plate 34 is fixed on the U-shaped frame 14, a mounting shell 35 is fixed on the mounting plate 34, an air pump 36 is fixed on the frame 1, the air outlet end of the air pump 36 is connected to the mounting shell 35 through a hose 2 37, a nozzle 39 is connected in the rectangular shell 32, and a hose 3 38 is connected between the mounting shell 35 and the nozzle 39.

[0025] When in use, the solid waste generated during the construction process is placed in the lower hopper 11, and the baffle 12 is driven by the cylinder 13 to slide backward in the lower hopper 11, and the solid waste will fall onto the crushing roller 15, and the crushing roller 15 is driven by the motor to rotate to crush the solid waste. After a long period of use, the surface temperature of the crushing roller 15 increases and it needs to be cooled. When dissipating heat, the U-shaped frame 14 and the crushing roller 15 are driven to move to both sides by the cylinder 2 16, and by starting the liquid pump 21, the coolant in the storage barrel 22 is pumped into the nozzle 23 through the pipe and the hose 1 24, and sprayed from the nozzle 23 to the surface of the crushing roller 15 for cooling. After cooling, the crushing roller 15 is driven to reset by the cylinder 2 16, and the crushing operation is performed again. This is the existing technology, so it will not be described in detail here.

[0026] Considering that after the crushing roller 15 crushes the solid waste, a large amount of dust and impurities will adhere to its surface, which will form a heat insulation layer, hindering the effective transfer of the coolant, and the surface impurities will affect the flow of the coolant on the roller surface, so that the coolant cannot be evenly distributed or flowed. This uneven coolant flow will lead to poor cooling effect in some areas, thereby increasing the risk of local overheating of the roller surface. The following improvements are now made: By setting a rectangular shell 32 and a brush 33 between the pulverizing roller 15 and the nozzle 23, when the pulverizing roller 15 moves to the position of the nozzle 23, the pulverizing roller 15 will contact the brush 33. Through the contact between the pulverizing roller 15 and the brush 33, some impurities and dust adhering to the surface of the pulverizing roller 15 can be scraped off to avoid the formation of a heat insulation layer by the covered dust and impurities, which hinders the effective transfer of the coolant and improves the cooling effect. Through the setting of the air pump 36, the gas is transmitted to the installation shell 35 through the hose 2 37, and enters the rectangular shell 32 through the hose 3 38, so that it is ejected from the nozzle 39, so that the gas is sprayed onto the surface of the pulverizing roller 15.

[0027] A further advantage of adopting the above method is that dust and impurities can be blown off by the cooperation between the flow of air and the brush 33, avoiding the scraped dust and impurities to remain on the surface of the crushing roller 15, thereby improving the removal effect. In addition, dust and impurities adhering to the surface of the brush 33 can also be blown off by the blowing of air flow, avoiding the dust and impurities from being re-covered when the brush 33 scrapes off dust and impurities in other parts of the crushing roller 15.

[0028] It should be noted that a PLC controller can be installed on the frame 1, and the PLC controller is electrically connected to the cylinder 13 and the cylinder 2 16, so that when the crushing roller 15 is cooled, the baffle 12 is located in the lower hopper 11, so that the opening of the lower hopper 11 is closed to prevent solid waste from falling. When the crushing roller 15 is cooled and reset, the baffle 12 opens to allow the solid waste to fall to avoid mutual influence. The number of nozzles 39 is not limited to one group, and a plurality of nozzles can be provided to improve the blowing effect.

[0029] Example 2, refer to Figure 1-Figure 9 A solid waste treatment equipment for construction engineering, comprising a frame 1, a crushing box 10 is fixed on the frame 1, a lower hopper 11 is connected to the crushing box 10, a baffle 12 is slidably arranged in the lower hopper 11, a cylinder 13 for driving the baffle 12 to move is installed on the crushing box 10, a U-shaped frame 14 is arranged in the crushing box 10, a crushing roller 15 is rotated in the U-shaped frame 14 through a bearing, a motor for driving the crushing roller 15 to rotate is installed on the U-shaped frame 14, a cylinder 2 16 for driving the U-shaped frame 14 to move is installed on the crushing box 10, and further comprising: A cooling mechanism 2 is arranged on the frame 1, and the cooling mechanism 2 is used to cool the crushing roller 15; The scraping mechanism 3 installed on the crushing box 10 is used to remove dust on the surface of the crushing roller 15 before the crushing roller 15 is cooled down.

[0030] Furthermore, an auxiliary mechanism 4 for vibrating the crushing roller 15 is provided on the U-shaped frame 14, and the auxiliary mechanism 4 includes a rotating rod 41 rotatably connected to the mounting plate 34 through a bearing, an impeller 42 is fixed to one end of the rotating rod 41 located in the mounting shell 35, a turntable 43 is fixed to one end of the rotating rod 41 away from the impeller 42, a push column 44 is fixed to the side of the turntable 43 away from the rotating rod 41, a moving shell 45 is slidably provided on the outer surface of the push column 44, a rectangular block 46 is fixed to the side of the mounting plate 34 close to the turntable 43, a piston rod 47 is fixed to the side of the moving shell 45 close to the rectangular block 46, the piston rod 47 is slidably connected to the rectangular block 46, and an impact bar 48 is fixed to the side of the moving shell 45 away from the piston rod 47.

[0031] Considering that some impurities and dust have strong adhesion, only scraping by brush 33 will result in poor removal effect of dust and impurities, and still affect the cooling effect. Now the following improvements are made: The impeller 42 is located in the mounting shell 35 and corresponds to the position of the hose 2 37. When the gas generated by the air pump 36 enters the mounting shell 35 through the hose 2 37, the impeller 42 is driven to rotate, and the impeller 42 drives the rotating rod 41 and the rotating disk 43 to rotate together. The rotating disk 43 drives the push column 44 to make a circular motion, and the piston rod 1 47 is slidably connected with the rectangular block 46 for limiting. Therefore, the push column 44 will push the moving shell 45 and the piston rod 1 47 to move left and right. The moving shell 45 drives the impact bar 48 to move intermittently left and right, so that the impact bar 48 properly impacts the U-shaped frame 14. When the U-shaped frame 14 is impacted, the U-shaped frame 14 and the crushing roller 15 will be vibrated.

[0032] A further benefit of adopting the above method is that dust and impurities with low adhesion can be removed more cleanly through vibration, and dust and impurities with high adhesion can be loosened more easily, making it easier for the brush 33 to scrape off, thereby improving the removal effect.

[0033] It should be noted that another alternative way to drive the impeller 42 to rotate by airflow is to install a motor in the mounting shell 35, wherein the output shaft of the motor is connected to the rotating rod 41, and the rotating rod 41 is driven by the motor to rotate, thereby ensuring that the impact bar 48 can impact the U-shaped frame 14 and the crushing roller 15, so that the U-shaped frame 14 and the crushing roller 15 vibrate.

[0034] Example 3, refer to Figure 1-Figure 9A solid waste treatment equipment for construction engineering, comprising a frame 1, a crushing box 10 is fixed on the frame 1, a lower hopper 11 is connected to the crushing box 10, a baffle 12 is slidably arranged in the lower hopper 11, a cylinder 13 for driving the baffle 12 to move is installed on the crushing box 10, a U-shaped frame 14 is arranged in the crushing box 10, a crushing roller 15 is rotated in the U-shaped frame 14 through a bearing, a motor for driving the crushing roller 15 to rotate is installed on the U-shaped frame 14, a cylinder 2 16 for driving the U-shaped frame 14 to move is installed on the crushing box 10, and further comprising: A cooling mechanism 2 is arranged on the frame 1, and the cooling mechanism 2 is used to cool the crushing roller 15; The scraping mechanism 3 installed on the crushing box 10 is used to remove dust on the surface of the crushing roller 15 before the crushing roller 15 is cooled down.

[0035] Furthermore, the auxiliary mechanism 4 is also provided with an adjusting mechanism 5 for adjusting the size of the air outlet of the nozzle 39, the adjusting mechanism 5 includes a liquid storage cylinder 51 fixed on the rectangular block 46, a piston rod 47 slides in the liquid storage cylinder 51, a piston disc 52 is fixed at one end of the piston rod 47 located in the liquid storage cylinder 51, the piston disc 52 slides in the liquid storage cylinder 51, the outer surface of the liquid storage cylinder 51 is connected with a hose 453, a fixed cylinder 54 is fixed on the crushing box 10, the end of the hose 453 away from the liquid storage cylinder 51 is connected with the fixed cylinder 54, a piston disc 2 55 slides in the fixed cylinder 54, a piston rod 2 56 is fixed on the piston disc 2 55, the piston rod 2 56 is slidably connected to the fixed cylinder 54, a spring 1 57 is sleeved on the outer surface of the piston rod 2 56, the two ends of the spring 1 57 are respectively fixedly connected to the fixed cylinder 54 and the piston disc 2 55, and an adjusting part 58 is provided on the piston rod 2 56.

[0036] Furthermore, the adjusting part 58 includes a rack 581 fixed to the end of the piston rod 56 away from the piston disc 55, a gear 582 is fixed to the outer surface of the rotating shaft 31, the rack 581 is meshed and connected with the gear 582, and a rotating rod 583 is fixed at the axis of the gear 582.

[0037] Furthermore, the adjusting part 58 also includes a connecting rope 584 fixed on the outer surface of the rotating rod 583, a rectangular bar 585 is slidably provided on the top wall of the rectangular shell 32, a lifting bar 586 is fixed to the bottom of the rectangular bar 585, a sealing disk 587 is fixed to the bottom of the lifting bar 586, and the sealing disk 587 corresponds to the position of the nozzle 39, and a spring 2 588 is sleeved on the outer surface of the rectangular bar 585, and the two ends of the spring 2 588 are respectively fixedly connected to the rectangular shell 32 and the lifting bar 586.

[0038] Furthermore, the adjustment portion 58 also includes a hose 589 connected to the liquid storage cylinder 51, an airbag 5810 is fixed to the bottom of the rectangular shell 32, the airbag 5810 is located between the brushes 33, and one end of the hose 589 away from the liquid storage cylinder 51 is connected to the airbag 5810.

[0039] It is connected to the piston rod 47 through the piston disc 52. When the piston rod 47 moves left and right, it will also drive the piston disc 52 to move together in the liquid storage cylinder 51. When the piston disc 52 moves, it will squeeze the liquid in the liquid storage cylinder 51, so that the liquid enters the fixed cylinder 54 through the hose four 53. After the piston disc 55 is squeezed by the liquid, it will drive the piston rod 56 to move in the direction of the rotating shaft 31 to squeeze the spring 57. When the piston disc 52 is reset, the elastic force of the spring 57 will also drive the piston disc 55 to reset. Therefore, through the movement of the piston disc 52, the rack 581 will also be driven to reciprocate. When the rack 581 moves, it will drive the gear 582 and the rotating shaft 31 to rotate, thereby driving the rectangular shell 32 and the brush 33 to rotate reciprocatingly.

[0040] A further benefit of adopting the above method is that the friction between the brush 33 and the crushing roller 15 can be increased by the reciprocating rotation of the rectangular shell 32 and the brush 33, thereby further improving the removal effect of the scraping mechanism 3.

[0041] Another use of this technology is: by connecting the rotating rod 583 with the gear 582, the rotation of the gear 582 will also drive the rotating rod 583 to rotate, thereby driving the connecting rope 584 to wrap around the outer surface of the rotating rod 583. Since the other end of the connecting rope 584 is connected to the rectangular bar 585, the winding of the connecting rope 584 will drive the rectangular bar 585 to move upward, causing the lifting bar 586 and the sealing disk 587 to move upward together, squeezing the spring 2 588, and when the rack 581 moves backward, the elastic force of the spring 2 588 will cause the sealing disk 587 to move downward, thereby intermittently reducing the air outlet of the nozzle 39.

[0042] A further benefit of adopting the above method is that the air outlet of the nozzle 39 can be synchronously and intermittently reduced. When the diameter of the air outlet is reduced, the flow rate of the gas passing through will increase, thereby increasing the intensity and impact force of the gas release and improving the removal effect of the scraping mechanism 3.

[0043] Another use of this technology is that when the piston disk 1 52 moves to the right in the liquid storage cylinder 51, it will also squeeze the gas in the liquid storage cylinder 51, allowing the gas to enter the airbag 5810 through the hose 5 589 to cause the airbag 5810 to intermittently expand.

[0044] A further benefit of adopting the above method is that the expansion of the airbag 5810 generates a driving force on the brush 33, making it easier to remove dust and impurities adhering to the brush 33, and again preventing the dust and impurities from re-covering other parts of the crushing roller 15 when the brush 33 scrapes off the dust and impurities, thereby further improving the removal effect.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
