Description

Technical Field

[0001] The invention relates to the technical field of construction waste recycling and treatment, and in particular to a bridge demolition construction solid waste recycling and treatment device. Background Art

[0002] Bridge engineering is a branch of civil engineering. Old bridges are usually demolished after being in disrepair or after river reconstruction. In the process of bridge demolition, concrete fragments are one of the main wastes, and their treatment and disposal methods directly affect the safety, environmental protection and efficiency of construction. A large number of concrete fragments will be generated during the bridge demolition process. Concrete fragments are common wastes in the process of bridge demolition. If these wastes are not properly handled, they will not only pollute the environment, but also waste precious resources. Due to the need to recycle and reuse these concrete fragments, the existing technology usually crushes the collected concrete fragments through professional crushing equipment to obtain recycled aggregates that meet the requirements. Recycled aggregates can be used as admixtures for new concrete. By adding a certain proportion, the demand for new raw materials is reduced and the construction cost is reduced. At the same time, recycled aggregates can also be used as filling materials for highway backfilling, soft foundation reinforcement and other projects, reducing the demand for natural stones.

[0003] For example, Chinese patent publication number CN221580726U discloses a concrete recycling device. It solves the technical problems that existing concrete recycling devices generate a lot of dust during the crushing process, part of the dust will float in the air, and when the crushing bin is opened for cleaning, the dust will float out. The concrete recycling device includes a box body, a feed port is arranged on the top of the box body, the feed port is connected to the external feeding device through a feed pipe, a guide plate is installed at the feed port, crushing roller 1 and crushing roller 2 are installed below the guide plate, a number of nozzles are arranged on both sides of crushing roller 1 and crushing roller 2, and the nozzles are connected to the water tank outside the box body, a filter plate is arranged below crushing roller 1 and crushing roller 2, an opening is arranged at the end of the filter plate to connect to the outside of the box body, a conveyor belt is arranged below the filter plate, a guide platform is arranged below the conveyor belt, and the end of the guide platform is connected to the external sewage treatment equipment through a drain pipe.

[0004] For example, Chinese patent publication number CN110665577B discloses a concrete waste recycling device for civil engineering, comprising a box, a feeding port at the top of the box, a discharging port at the bottom of the box, two crushing rollers with motors movably mounted between the inner walls at the front and rear ends of the box, the two crushing rollers meshing with each other, a support plate hingedly mounted on the inner wall at the rear end of the box, the support plate being located below the crushing rollers, a groove being disposed at the front end of the support plate, and the inner walls on both sides of the groove being connected to the outside. The present invention can be used to recycle metals containing iron, cobalt and nickel in crushed construction waste, and also to crush construction waste.

[0005] For example, Chinese patent publication number CN221288025U discloses a recyclable concrete block device, comprising: a crushing box, the outer surface of which near the lower end is fixedly mounted with a support frame, and also comprising: two rotating shafts, both of which are movably embedded in the inner part of the crushing box near the upper end, and the outer surfaces of the two rotating shafts are fixedly sleeved with crushing rollers. The dismantled concrete blocks are delivered to the interior of the crushing box through the feeding funnel, and the driving motor is turned on to drive one of the rotating shafts to rotate. Gears are fixedly mounted at one end of the two rotating shafts. When one rotating shaft rotates, the other rotating shaft is driven to rotate through the gears. The two rotating shafts drive the crushing rollers to rotate relative to each other, so that the concrete blocks can be better crushed. A protective cover is fixedly mounted on the top of the crushing box, which can play a protective role.

[0006] When the above-mentioned concrete waste recycling and processing devices in the prior art are in use, the distance between adjacent crushing rollers is kept constant and difficult to adjust. The concrete fragments are crushed into high fineness at one time by two crushing rollers. Since the concrete fragments are of different sizes, it is easy for the crushing rollers to be locally overloaded due to the large fragments.

During the crushing process of the fragments by the crushing component 1, the size of the space in the crushing component 1 that allows the crushed stones to pass through is constantly changing, and stones of different sizes can be adaptively squeezed and crushed. At the same time, the crushing component 1 drives the feeding component 2 to feed the crushed crushed stones to the crushing component 1 again for repeated crushing, thereby forming a situation in which the large fragments are gradually squeezed and decomposed into smaller fragments that fall out of the bottom of the processing tube 5. As the fragments are repeatedly fed to the crushing component 1, they are crushed from smaller pieces into smaller pieces again, and the crushing process is repeated. The crushing roller is used for crushing the crushed stone into a large size by the combination of the crushing component 1 and the feeding component 2, and the crushing fineness of the crushed stone is gradually increased to form crushed stone. The gradual crushing method ensures that the crushed stone can be evenly stressed, which greatly reduces the overload problem of the crushing roller caused by the large crushed stone. It can flexibly deal with crushed stone of various sizes, and effectively improves the crushing efficiency and uniformity. At the same time, the crushed stone is intermittently fed to the crushing component 1 for crushing through the provided feeding component 2, which avoids the blockage and uneven crushing caused by continuous feeding, reduces the load of the crushing roller, and prolongs the service life of the equipment. Further, the intermittent feeding helps to adjust the crushing rhythm and makes the crushing process more It is smooth and controllable, and improves the safety and stability of the overall operation; the unloading component 3 is set to make the unloaded fragments fall in an S-shaped path, and the falling of the fragments is cushioned, thereby effectively reducing the impact force of the fallen fragments on the fragment component 1, effectively reducing the impact of the falling fragments on the fragment component 1, and effectively improving the protection of the fragment component 1; when the fragments inside the processing tube 5 are crushed into fragments, the cover plate 8 is opened to open the open end of the processing tube 5, and the support plate 7 is tilted by the set pouring component 4, so that the open end of the processing tube 5 faces downward, so that the fragments inside the processing tube 5 can be automatically poured out, which is convenient for taking out materials, effectively improving the taking out efficiency, eliminating the operation of manually reaching into the processing tube 5 to take out materials, and saving manpower.

During the crushing process, the crushing roller 101 crushes the fragments. Due to the eccentric design of the end shaft 102 on one of the crushing rollers 101, the spacing gap between the two crushing rollers 101 is constantly adjusted, so that the two crushing rollers 101 can adaptively extrude and crush stones of different sizes, thereby gradually crushing large fragments into smaller fragments that fall out to the bottom of the processing cylinder 5. As the fragments are repeatedly delivered to the crushing roller 101, they are crushed from smaller fragments into smaller fragments again, and the process is repeated. Compared with the prior art method of crushing the fragments into high fragmentation at one time, the crushed stones are gradually crushed from large to small, and the fineness of the fragments is gradually increased into fragments. The gradual crushing method ensures that the crushed stones can be evenly stressed, greatly reducing the problem of crushing roller overload caused by excessively large fragments, and can flexibly deal with fragments of various sizes, effectively improving the crushing efficiency and uniformity.

[0038] Further as Figure 2 , Figure 4 , Figure 5 , Figure 7 and Figure 8As shown, it is worth specifically explaining that the feeding assembly 2 includes an inner cylinder 201 which is fitted with the inner wall of the processing cylinder 5, one end of the inner cylinder 201 is rotatably connected to the closed end side wall of the processing cylinder 5 through a bearing, and the end of the inner cylinder 201 is extended from the interior of the processing cylinder 5, and a plurality of meshing teeth 202 distributed in an annular shape are fixed on the end of the inner cylinder 201 extending from the interior of the processing cylinder 5, and the meshing teeth 202 are meshed and connected with the second gear 104, and a material stripping plate 203 is fixed on the inner wall of the inner cylinder 201; during specific operation, the rotating second gear 104 and the meshing teeth 202 cooperate to drive the inner cylinder 201 to rotate slowly, so that the fragments that fall to the bottom of the processing cylinder 5 are continuously stripped and put into the top of the crushing roller 101 through the plurality of material stripping plates 203 on the inner cylinder 201, so that the crushing roller 101 can repeatedly crush the fragments, effectively ensuring the adequacy of the crushing.

The multiple partitions 302 are used to buffer the falling of the fragments, thereby reducing the impact of the falling fragments on the crushing roller 101. When the first feed port 204 and the second feed port 304 on the rotating built-in cylinder 201 coincide with each other, the fragments temporarily stored in the material discharge shell 301 are passed through the material discharge shell 301. The crushed pieces are fed to the crushing roller 101 through the second feed port 304 and the first feed port 204 for crushing. When the first feed port 204 on the inner cylinder 201 turns away from the second feed port 304, the solid side wall of the inner cylinder 201 blocks the second feed port 304, thereby intermittently feeding the crushed pieces to the crushing roller 101 for crushing.
