Description

Technical Field

[0001] This utility model relates to the field of concrete waste technology, and in particular to a prefabricated concrete waste recycling and separation device. Background Technology

[0002] After a concrete truck finishes unloading, concrete residue will remain on the exterior of the truck body, wheels, unloading chute, and inside the mixing drum. The concrete residue inside the mixing drum, in particular, can damage the vehicle's equipment and affect its normal use. Moreover, an uncleaned concrete truck will not only cause road pollution and affect the city's image, but also reduce the purity of the concrete and affect the quality of the concrete pouring. The conventional methods for cleaning concrete trucks are generally: washing them directly on the construction site without taking any anti-fouling equipment or facilities; or using a brick-built concrete truck washing pool for cleaning.

[0003] The conventional method of cleaning concrete trucks has the following problems:

[0004] First, it wastes resources. The concrete waste produced during cleaning includes coarse aggregate, fine aggregate, and water. Conventional practices do not separate the waste, so the useful materials in the waste cannot be reused.

[0005] Second, it damages the image of civilized construction. Cleaning without any equipment or facilities will pollute the environment inside and around the site and increase the difficulty of managing the construction site.

[0006] Third, it increases construction costs. In order to avoid pollution to the environment caused by direct washing, it is necessary to take anti-pollution measures, such as adding anti-pollution equipment or facilities, which will increase construction costs.

[0007] Fourth, it cannot be reused. The construction of brick concrete car wash pools on site usually requires excavating a foundation pit, pouring a foundation layer, and finally building a brick formwork. The construction cycle is long and it is a one-time investment. As the construction site is adjusted, the brick concrete car wash pools cannot be reused. Utility Model Content

Detailed Implementation

[0040] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments, so that the purpose, technical solution and advantages of the present invention will be clearer. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0041] This embodiment illustrates a prefabricated concrete waste recycling and separation device, referencing... Figures 1-2The device includes a protective system 1, a lifting system 2, a collection system 3, and a dividing system 4. The protective system 1 is used for structural load-bearing of the device. The protective system 1 is a cuboid or cube with openings at the top and bottom. The specific dimensions of the protective system 1 can be adjusted according to actual needs. The lifting system 2 is located on top of the protective system 1. The collection system 3 is located inside the protective system 1. The lifting system 2 is used to lift the collection system 3 to the top of the protective system 1. The collection system 3 includes a collection tank 31 and a sedimentation tank 32. The collection tank 31 is used to collect coarse aggregate from concrete waste. The sedimentation tank 32 is used to collect fine aggregates and water from concrete waste. The dividing system 4 is set inside the sedimentation tank 32, dividing the sedimentation tank 32 into a primary sedimentation tank 321 and a secondary sedimentation tank 322. The collection tank 31 is detachably connected to the protection system 1 and is located above the primary sedimentation tank 321. After the coarse aggregates of the concrete waste are collected by the collection tank 31, the fine aggregates and water enter the primary sedimentation tank 321 for sedimentation. After sedimentation, the water containing a small amount of fine aggregates enters the secondary sedimentation tank 322 through the dividing system for further separation and collection.

[0042] The protective system 1 includes horizontal bars 11, vertical bars 12, support bars 13, and protective side plates 14. The four vertical bars 12 are located at the four corners of the rectangle. The tops and bottoms of adjacent vertical bars 12 are connected by horizontal bars 11 to form the load-bearing skeleton of the protective system 1. The two adjacent horizontal bars 11 at the top and the two adjacent horizontal bars 11 at the bottom of the protective system 1 are fixedly connected to the vertical bars 12 by connecting tees 15. Multiple support bars 13 are vertically connected between the horizontal bars 11 at the top and bottom of the protective system 1. The multiple support bars 13 are arranged side by side on the horizontal bars 11 and are located on the inner or outer side of the protective system 1. The protective side plates 14 are arranged around the protective system 1 and are located on the outer side of the protective system 1.

[0043] Both the horizontal rod 11 and the vertical rod 12 are composed of rod one 101 and rod two 102. Rod two 102 is used to insert into rod one 101 to adjust its length. Rod one 101 is made of galvanized steel pipe with a diameter of 40mm and a wall thickness of 2mm, and rod two 102 is made of galvanized steel pipe with a diameter of 30mm and a wall thickness of 2mm. The first end of rod two 102 is inserted into the first end of rod one 101 and is movably connected to rod one 101. Anchor holes 16 with a diameter of 10mm are opened at equal intervals on rod one 101. Circular holes one (not shown in the figure) are opened at equal intervals on rod two 102, connecting rod two 102. The distance between two adjacent circular holes one is equal to the distance between two adjacent anchor holes 16. An anchor rod 17 is provided at one of the circular holes. After the anchor rod 17 is inserted into the anchor hole 16, it connects rod one 101 and rod two 102. The anchor rod 17 includes a spring 171 and an anchor rod 172 (see reference). Figure 12The spring 171 is connected to an anchor rod 172 at each end. The spring 171 is located inside the second rod 102. The anchor rod 172 extends out of the second rod 102 through the first round hole. The anchor rod 172 is a round tube with a diameter smaller than that of the anchor hole 16. When the anchor rod 172 is pressed, the spring 171 deforms under the pressure from the anchor rod 172. The end face of the anchor rod 172 enters the interior of the anchor hole 16 but still exceeds the surface of the second rod 102. This facilitates the movement of the second rod 102 inside the first rod 101 and the adjustment of its length. When the anchor rod 172 moves to any anchor hole 16, the pressure of the spring 171 is released, and the end face of the anchor rod 172 exceeds the anchor hole 16, fixing the positions of the first rod 101 and the second rod 102. An anchor rod 17 is provided at the anchor hole 16 near the second end of the first rod 101, with the first end and the second end of the first rod 101 facing each other.

[0044] The connecting tee 15 includes two horizontal connecting parts 151 and two vertical connecting parts 152. Figure 13 The connecting tee 15 is made of a galvanized round pipe with a diameter of 50mm. The two horizontal connecting parts 151 are perpendicular to the horizontal plane and respectively perpendicular to the vertical connecting part 152 on the vertical plane. Both the horizontal connecting part 151 and the vertical connecting part 152 are provided with connecting holes 153 (see reference). Figure 13 The cross-section of the connecting hole 153 is circular, and the diameter of the connecting hole 153 is adapted to the diameter of the anchor rod 172 of the anchor rod 17. The horizontal connecting part 151 is used to connect the horizontal rod 11. When the horizontal connecting part 151 is connected to the first rod 101 of the horizontal rod 11, the anchor rod 17 on the second end of the first rod 101 is detachably connected to the horizontal connecting part 151 through the connecting hole 153. Alternatively, when the horizontal connecting part 151 is connected to the second rod 102 of the horizontal rod 11, the anchor rod 17 near the second end of the second rod 102 is connected to the anchor rod 172 through the connecting hole 153. The vertical connecting part 152 is used to connect the vertical rod 12. The first rod 101 of the vertical rod 12 is connected to the vertical connecting part 152 at the top of the protection system 1. The anchor rod 17 on the second end of the first rod 101 is detachably connected to the vertical connecting part 152 through the connecting hole 153. The second rod 102 of the vertical rod 12 is connected to the vertical connecting part 152 at the bottom of the protection system 1. The anchor rod 17 near the second end of the second rod 102 is detachably connected to the vertical connecting part 152 through the connecting hole 153.

[0045] The support rod 13 is parallel to the vertical rod 12. The support rod 13 is made of ribbed steel bar with a diameter of 20mm. The support rod 13 is fixedly connected to the horizontal rod 11 by welding. One end of the support rod 13 is connected to the horizontal rod 11 at the top of the protection system 1, and the other end is connected to the horizontal rod 11 at the bottom of the protection system 1. The support 13 is used to increase the structural strength of the protection system 1. As a preferred embodiment, two adjacent support rods 13 are provided at the connection part of the first rod 101 and the second rod 102 of the horizontal rod 11 (for example, the two support rods are 0~5cm apart). One support rod 13 is located on the first rod 101 and close to the first end of the first rod 101, and the other support rod 13 is located on the second rod 102 and close to the first end of the first rod 101 (both adjacent support rods can be located on the first rod and close to the first end of the first rod). When the horizontal rod 11 is long (e.g., the length is greater than 3m), the two additional support rods 13 can further increase the structural stability. The support rod 13 is provided with a collection trough hook 110 for attaching the collection trough 31.

[0046] An anchor plate 18 is also provided on the vertical rod 12 (see reference). Figure 7 Anchor plates 18 are welded to the first 101 of the vertical rod 12. The anchor plates 18 are symmetrically arranged on the first 101, located on both sides of the anchor rod 17 at the second end of the first 101, and maintaining a certain distance from the anchor rod 17. The two anchor plates 18 are used for the installation of two adjacent protective side plates 14 on the protective system 1, without affecting the anchor rod 17 on the second 102 of the vertical rod 12 passing through the anchor hole 16 on the first 101. The length of the anchor plate 18 is adapted to the length of the first 101. The cross-section of the anchor plate 18 is a right-angled L-shape. The anchor plate 18 is made of 5mm thick angle steel. The first right-angled side of the anchor plate 18 is perpendicularly connected to the first 101, and the second right-angled side is parallel to the first 101 and parallel to the first 101. A certain distance is maintained, which is adapted to the thickness of the protective side plate 14. The anchor plate 18 and the rod 101 form a slot for installing the protective side plate 14. The slot is used to fix and prevent the protective side plate 14 from falling off. As a preferred embodiment, a baffle 111 is provided on the first right-angled side of the anchor plate 18. The baffle 111 is used to improve the stability of the installation of the protective side plate 14. The baffle 111 is perpendicularly connected to the first right-angled side of the anchor plate 18 and parallel to the second right-angled side of the anchor plate 18. The baffle 111 is located between the second right-angled side of the anchor plate 18 and the rod 101 of the vertical rod 12. A certain distance is maintained between the baffle 111 and the second right-angled side of the anchor plate 18, which is adapted to the thickness of the protective side plate 14.

[0047] During application, anchor plates and baffles can also be installed on the second pole 102 of the vertical pole 12 to further improve the stability of the protective side plate 14 installation. The anchor plates and baffles are installed on the second pole 102 in the same way as they are installed on the first pole 101. In the height direction of the second pole 102, the top of the anchor plates and baffles is a certain distance away from the first end of the second pole 102. The distance does not hinder the length adjustment of the vertical pole 12.

[0048] The protective side plate 14 is made of 4mm thick patterned steel plate. The height of the protective side plate 14 is adapted to the height of the protective system 1, and the width of the protective side plate 14 is adapted to the width of the protective system 1. The protective side plate 14 is used to improve the structural stability of the protective system 1 and also to provide external protection for the collection system 3. (Reference) Figure 5 The protective side plate 14 includes a fixed protective plate 141 and a movable protective plate 142. The fixed protective plate 141 and the movable protective plate 142 are movably connected by a sliding groove 19, which is respectively arranged on the upper and lower sides of the fixed protective plate 141. Figure 5 At both ends (up and down direction), the length of the slide groove 19 is equal to the width of the fixed protective plate 141, and the cross-section of the slide groove 19 is a right-angled L-shape (see reference). Figure 6 The first right-angled side of the slide groove 19 is fixedly connected to the fixed protective plate 141, and the second right-angled side is parallel to the fixed protective plate 141 and forms an opening. The width of the opening is adapted to the thickness of the movable protective plate 142. The opening at the upper end of the fixed protective plate 141 faces downward and the opening at the lower end of the fixed protective plate 141 faces upward. The first end of the movable protective plate 142 is inserted from the first end of the fixed protective plate 141. The top and bottom of the movable protective plate 142 are respectively inserted into the upper and lower openings of the fixed protective plate 141, and the width of the protective side plate 14 is adjusted by moving it along the length direction of the slide groove 19.

[0049] The protective side plate 14 is disposed between two adjacent vertical rods 12. The protective side plate 14 is movably connected to the anchor plate 18 on the vertical rod 12. The second end of the movable protective plate 142 is disposed in an anchor plate 18 on one vertical rod 12, with the first and second ends of the movable protective plate 142 facing each other. The second end of the fixed protective plate 141 is disposed in an anchor plate 18 on another adjacent vertical rod 12, with the first and second ends of the fixed protective plate 141 facing each other. The two anchor plates 18 connecting the protective side plate 14 are located on the same side of the protective side plate 1. When the length and width dimensions of the protective system 1 are long, multiple sets of protective side plates 14 can be disposed on each side of the protective system 1 to increase the protective effect. The anchor plate 18 is also disposed on the support rod 13. The anchor plate 18 is located on the support rod 13 near the first end of the rod 101. The first right-angled side of the anchor plate 18 is perpendicularly connected to the support rod 13, and the second right-angled side of the anchor plate 18 extends toward the second end of the rod 101. Anchor plate 18 is also located on support rod 13 near the first end of rod 102. The first right-angled side of anchor plate 18 is perpendicularly connected to support rod 13, and the second right-angled side of anchor plate 18 extends towards the second end of rod 102. The baffle 111 is perpendicularly connected to the first right-angled side of anchor plate 18 and parallel to the second right-angled side of anchor plate 18. The baffle 111 is located between the second right-angled side of anchor plate 18 and support rod 13. The baffle 111 is perpendicular to the second right-angled side of anchor plate 18. A certain distance is maintained at the edge, which is adapted to the thickness of the protective side plate 14. The second end of the movable protective plate 142 is set in an anchor plate 18 on a vertical rod 12, and the second end of the fixed protective plate 141 is set in an anchor plate 18 on an adjacent support rod 13. Alternatively, the second end of the fixed protective plate 141 is set in an anchor plate 18 on a vertical rod 12, and the second end of the movable protective plate 142 is set in an anchor plate 18 on an adjacent support rod 13.

[0050] refer to Figure 8 The lifting system 2 includes a lifting device 21 and a transmission device 22. Two sets of parallel lifting devices 21 are located on top of the protection system 1. The two sets of lifting devices 21 are connected by the transmission device 22. When power is applied to make one set of lifting devices 21 rotate, the transmission device 22 transmits the power to the other set of lifting devices 21, and the other set of lifting devices 21 also rotates under the drive of the transmission device 22.

[0051] Each lifting device 21 includes a lifting sleeve 211, a lifting shaft 212, and a lifting gear 213. The lifting sleeve 211 is made of galvanized steel pipe with a diameter of 40mm and a wall thickness of 2mm. The lifting sleeve 211 is used to protect the lifting shaft 212 and provide space for the lifting shaft 212 to rotate. Both ends of the lifting sleeve 211 are fixedly connected to the protection system 1 by fixing members 23. The fixing members 23 are fixedly installed on the connecting tee 15 at the top of the protection system 1 and are located on a horizontal connecting part 151 of the connecting tee 15. The horizontal rod 11 connected to the horizontal connecting part 151 is perpendicular to the lifting sleeve 211. The fixing member can also be set on a horizontal bar. The distance between the two lifting sleeves can be adjusted according to the setting position of the fixing member on the horizontal bar. The cross-section of the fixing member 23 is L-shaped. One side of the fixing member 23 is perpendicularly connected to the horizontal connecting part 151, and the other side is parallel to the horizontal connecting part 151 and extends in the length direction of the horizontal connecting part 151. The lifting sleeve 211 is fixedly connected to the other side of the fixing member 23. Slots (not shown in the figure) are respectively opened at both ends near the lifting sleeve 211. The slots are located between the two fixing members 23 connected to the lifting sleeve 211 (more slots can be set in the length direction of the lifting sleeve).

[0052] The lifting shaft 212 is housed inside the lifting sleeve 211, with both ends extending out of the sleeve. The lifting shaft is made of 20mm diameter round steel bar. A 60mm diameter hexagonal nut 24 is installed at the first end of the lifting shaft 212, with a diameter larger than that of the lifting sleeve 211. The nut prevents the lifting shaft 212 from detaching from the first end of the lifting sleeve 211 during rotation. A rotating shaft 25 is installed at the second end of the lifting shaft 212, with the first and second ends facing each other. The rotating shaft 25 drives the lifting shaft 212 to rotate. The cross-section of the rotating shaft 25 is L-shaped (see reference). Figure 1 One side of the rotating shaft 25 is perpendicular to and fixedly connected to the lifting shaft 212, and the other side of the rotating shaft 25 extends away from the lifting shaft 212. By holding the other side of the rotating shaft 25 and applying force to it, the rotating shaft 25 makes a circular motion, and the lifting shaft 212 also rotates under the drive of the rotating shaft 25.

[0053] As one preferred embodiment, reference is made to Figure 15The second end of the lifting shaft 212 is connected to the electric device 29. A gear 214 is provided at the second end of the lifting shaft 212, and a gear 210 is provided on the output shaft of the electric device 29. Gear 214 and gear 210 mesh with each other. The electric device 29 provides power for the rotation of the lifting shaft 212.

At the same time, the distance between the guide pipe 44 and the bottom of the fixed compartment plate 41 increases as the movable compartment plate 42 is raised, which is conducive to the primary sedimentation tank 321 collecting more fine aggregate and water. After the fine aggregate in the primary sedimentation tank 321 has settled, the movable compartment plate 42 is lowered so that the bottom of the movable compartment plate 42 contacts the bottom of the fixed compartment plate 41. The distance between the guide pipe 44 and the bottom of the fixed compartment plate 41 decreases as the movable compartment plate 42 is lowered, which is conducive to introducing the water settled in the primary sedimentation tank 321 into the secondary sedimentation tank 322 for further sedimentation.

[0061] When using this device to collect concrete waste, place the device on a flat surface, drive the concrete truck next to the device, and position the truck's unloading chute above the collection tank 31. After cleaning the concrete truck's hopper and mixing drum, discharge the concrete waste from the hopper and mixing drum into the collection tank 31 via the unloading chute. After the coarse aggregate is collected in the collection tank 31, the fine aggregate and water enter the primary sedimentation tank 321 for sedimentation. At this time, lift the top of the movable compartment plate 42 to the top of the fixed compartment plate 41, causing the guide tube 44 to move upward, and pass the fixing rod through the fixing ring, setting both ends of the fixing rod on the two opposite side plates 34; when the primary sedimentation tank 321... After sedimentation is complete, the fixed rod is pulled out, causing the movable compartment plate 42 to descend to the bottom of the fixed compartment plate 41. At this time, the guide tube 44 moves down, diverting the water in the primary sedimentation tank 321 to the secondary sedimentation tank 322 for further sedimentation, and then pumping away the sedimented water. After the final separation and collection of concrete waste is completed, the lifting hook 273 on the lifting system 2 is attached to the long horizontal bar 3111 at the top of the collection trough 31, and the collection trough 31 is lifted to the top of the protection system 1 for the transfer of coarse aggregate. The lifting hook 273 on the lifting system 2 is attached to the lifting ring on the sedimentation tank 32, and the sedimentation tank 32 is lifted to the top of the protection system 1 for the transfer of fine aggregate.
