Description

TECHNICAL FIELD

[0001] The present application relates to the field of highway engineering, and particularly relates to a concrete aggregate processing device. BACKGROUND

[0002] In the process of reconstruction and expansion of highway engineering, the demolished roadbed, bridge and other waste concrete structures are crushed to prepare recycled concrete aggregates. The recycled concrete aggregates can be used for pouring and precasting of highway concrete drainage structures, or for gravel cushion, cement stabilized gravel subbase, base and other parts. However, the recycled concrete aggregates contain mortar and have a large water absorption rate, generally between 5% and 8%. If the recycled concrete aggregates are directly used without treatment, the slump of the concrete will greatly decrease, thereby seriously reducing the workability of the concrete. Therefore, when the recycled concrete aggregates are used, they need to be pre-absorbed and / or modified.

[0003] In the prior art, when the recycled concrete aggregates are pre-absorbed and / or modified, some methods directly pour water and / or modifier on the recycled concrete aggregates. In this method, the recycled concrete aggregates stacked inside cannot be effectively pre-wetted, and the pre-absorption effect is poor. In addition, some methods directly pour the recycled concrete aggregates into a device containing water and / or modifier for soaking, and then the soaked recycled concrete aggregates are fished out and laid flat for drying. This method has a low processing efficiency. In addition, the water and / or modifier used in the prior art cannot be reused. CONTENT OF THE UTILITY MODEL

[0013] In the embodiment of the present application, the concrete aggregate treatment device further comprises a second filter layer, which is located between the first filter layer and the liquid storage pool, and the second filter layer extends from the spraying area to the storage area.

[0014] The second filter layer is a one-way filter layer, the passing direction of the second filter layer is from top to bottom, and the filtering diameter of the second filter layer is smaller than the filtering diameter of the first filter layer.

[0015] In the embodiment of the present application, the draining frame comprises a bottom plate and two side plates, the two side plates are arranged on the opposite sides of the bottom plate, and the two side plates are located on the same side of the bottom plate.

[0016] The bottom plate is a mesh structure, the top of the draining frame is open in the vertical direction, and the two ends of the draining frame are open in the extension direction of the conveying belt.

[0018] Each pulley block comprises a first pulley and a second pulley, the first pulley and the second pulley are hung on the conveying belt, and the first pulley and the second pulley are capable of moving with the conveying belt.

[0019] Along the extension direction of the conveying belt, the two ends of any draining frame are respectively hoisted on the first pulley and the second pulley of the corresponding pulley block.

[0020] In the embodiment of the present application, the storage area is provided with a material falling slide, and the height of the material falling slide gradually decreases from one end close to the draining area to the other end along the conveying direction of the conveying belt.

[0034] like Figure 1 As shown in the embodiment of this application, the concrete aggregate processing device includes:

[0035] A storage tank 100 is used to store water and / or a modifier;

[0036] In the vertical direction, a treatment area is provided above the storage tank 100. The treatment area includes a spraying area 200 and a draining area 210. In the direction of concrete aggregate conveying, the spraying area 200 and the draining area 210 are arranged adjacent to each other.

[0037] A water supply channel 300 extends from the liquid storage tank 100 to above the spray area 200. A spray head 310 is provided at the part of the water supply channel 300 above the spray area 200, and the spray direction of the spray head 310 is towards the spray area 200.

[0038] Conveyor belt 400 extends from the spraying zone 200 to the draining zone 210;

[0039] At least one drain frame 500 is provided on the conveyor belt 400 and can be conveyed along the conveyor belt 400. The drain frame 500 is used to hold concrete aggregate to be processed.

[0040] like Figure 1 As shown in this embodiment, the storage tank 100 is used to store water or a modifier, or a mixture of water and a modifier. The storage tank 100 has a holding space for holding water and / or the modifier. The size of the storage tank 100 is determined based on the amount of concrete aggregate to be processed. If the amount of concrete aggregate to be processed is large, a larger storage tank 100 can be provided; if the amount of concrete aggregate to be processed is small, a smaller storage tank 100 can be provided. Furthermore, the storage tank 100 can be made of materials that are not corroded by water and / or the modifier, such as plastic or metal, or it can be made using building materials such as concrete.

[0041] Continue to refer to Figure 1 The liquid storage tank 100 is located at the bottom, and it can be located on the ground or underground. This embodiment of the application does not limit the specific location of the liquid storage tank 100. Additionally, as... Figure 1 As shown, the treatment zone is located above the storage tank 100 in the vertical direction. The treatment zone is used to treat concrete aggregates. The treatment zone includes a spraying zone 200 and a draining zone 210. The spraying zone 200 is used to spray water and / or modifiers onto the concrete aggregates to be treated. The draining zone 210 is used to drain the sprayed concrete aggregates. In the conveying direction of the concrete aggregates in the treatment zone, the spraying zone 200 and the draining zone 210 are adjacent, so that the concrete aggregates to be treated can quickly enter the draining zone 210 for draining after being sprayed in the spraying zone 200, thereby improving the treatment efficiency.

[0042] like Figure 1As shown in this embodiment, the water supply channel 300 extends from the storage tank 100 to above the spray area 200. One or more spray heads 310 can be installed above the spray area 200 in the water supply channel 300, with the spray heads 310 facing the spray area 200. During use, a drive pump, in conjunction with the water supply channel 300, drives the water and / or modifier from the storage tank 100 to above the spray area 200, and sprays it onto the spray area 200 from the spray heads 310. Compared to the prior art of directly pouring water and / or modifier onto recycled concrete aggregate, this application uses spray heads 310. The spray heads 310 can spray atomized particles of water and / or modifier with very small particle diameters, facilitating rapid absorption by the recycled concrete aggregate. Furthermore, the spray area of ​​the spray heads is large, resulting in higher processing efficiency. Additionally, when multiple spray heads 310 are installed, they can have different orientations. For example, multiple spray heads can spray water from all sides of the drain frame 500 within the spray area 200, thereby ensuring that the recycled concrete aggregate within the drain frame 500 can be sprayed evenly, improving the pre-absorption and / or absorption effect.

[0043] Alternatively, the water supply channel can be based on a pipe. For example, the water supply channel can be a water supply pipe, with one end connected to the storage tank 100 and the other end extending upwards to above the spray area 200. The spray head 310 is located above the spray area 200 on the water supply pipe. Alternatively, one end of the water supply pipe can be connected to the storage tank 100, and the other end can extend upwards to above the spray area 200, then cross the spray area 200 and extend downwards into the storage tank 100, with the spray head 310 located above the spray area 200 on the water supply pipe. Besides water supply pipes, the water supply channel can also be a channel directly constructed from building materials, with its bottom connected to the storage tank 100 and extending upwards to above the spray area 200. The spray head 310 is located above the spray area 200 on the channel.

[0044] In addition, such as Figure 1 As shown in the embodiment of this application, the direction of travel of the concrete aggregate to be treated during the treatment process is from left to right in the horizontal direction. The water supply channel 300 can start from the storage tank 100 and extend upward from both sides of the direction of travel of the concrete aggregate to be treated to the top of the spray area 200 in the horizontal direction, thereby ensuring that the water supply channel 300 will not interfere with the travel route of the concrete aggregate to be treated and reducing the length of the water supply pipe.

[0045] Continue to refer to Figure 1In the embodiment of the present application, the conveying belt 400 is arranged in the treatment area, and the conveying belt 400 extends in the direction from the spraying area 200 to the draining area 210. The height position of the conveying belt 400 in the treatment area can be above the spraying area 200 and the draining area 210, or can pass through the spraying area 200 and the draining area 210. When the conveying belt 400 is above the spraying area 200 and the draining area 210, the hanging height of the draining frame 500 can be set to be in the spraying area 200 when the draining frame 500 is hung on the conveying belt, so that the draining frame 500 can be sprayed. In addition, the conveying belt 400 can be driven by a driving motor. For example, a driving motor and a speed reducer are arranged. The driving motor provides driving force to the conveying belt 400 after being decelerated by the speed reducer. By controlling the switch of the driving motor, the draining frame can be advanced or stopped.

[0046] The draining frame 500 is arranged on the conveying belt 400, and the draining frame 500 can be conveyed along with the conveying belt 400. In addition, the draining frame 500 can pass through the spraying range of each spraying head 310 during the advancing process. Therefore, when the draining frame 500 advances to the spraying area 200, the spraying head 310 can spray the treated concrete aggregate in the draining frame 500, so that the treated concrete aggregate in the draining frame 500 can be fully sprayed. After spraying, the draining frame 500 can be directly conveyed to the draining area 210 along the conveying belt 400 for draining, so that the treatment efficiency can be improved. In addition, part of the water and / or modifier sprayed by the spraying area 200 can adhere to the concrete aggregate in the draining frame 500, and the other part can fall back into the storage tank 100. In addition, during the draining process of the draining frame 500 in the draining area 210, the dripping water and / or modifier can also fall into the storage tank 100, that is, the water and / or modifier can also be recycled.

[0047] As shown in Figure 1 In the embodiment of the present application, the treatment area further includes a storage area 220. The storage area 220 is located behind the draining area 210 along the extension direction of the conveying belt 400, and the conveying belt 400 extends to the storage area 220. In the direction shown in Figure 1 The advancing direction of the treated concrete aggregate during the treatment process is from left to right. Therefore, the storage area 220 can be arranged on the right side of the draining area 210, and the conveying belt 400 can be arranged to extend to the storage area 220. Therefore, after the treated concrete aggregate is drained in the draining area 210, the draining frame 500 continues to convey to the storage area 220 along the conveying belt 400 for unloading. The unloaded concrete aggregate can be stored in the storage area 220, or can wait for the next treatment in the storage area 220.

[0048] In addition, it should be noted that the concrete aggregate cannot be completely drained when drained in the draining area 210, and when the concrete aggregate enters the storage area 220 for storage, part of the water and / or modifier may still remain in the concrete aggregate. Therefore, in the horizontal direction, the liquid receiving range of the storage tank 100 needs to completely cover the storage area 220, so that the water and / or modifier remaining in the concrete aggregate stored in the storage area 220 can all flow back to the storage tank 100.

[0049] As shown in Figure 1 In the embodiment of the present application, the concrete aggregate treatment device further comprises a first filter layer 610, which is located between the storage tank 100 and the treatment area, and extends from the spraying area 200 to the storage area 220. In the embodiment of the present application, the first filter layer 610 can be a water draining grate or other components with water filtering function.

[0050] In addition, the first filter layer 610 can extend from the spraying area 200 to the storage area 220, and in the horizontal direction, the filtering radiation range of the first filter layer 610 is the same as or slightly larger than the area of the storage tank 100. During the spraying process, the draining process, and the storage process in the storage area 220, the water and / or modifier dripping from the treated concrete aggregate can all flow back to the storage tank 100, while the aggregate particles falling during the above processes are blocked by the first filter layer 610 to prevent them from falling into the storage tank 100. In addition, the first filter layer 610 can also have a supporting effect, for example, the part of the first filter layer 610 extending to the storage area can also be used to bear the weight of the treated concrete aggregate and the weight of other objects, such as the weight of the transportation tool for transporting the treated concrete aggregate.

[0051] As shown in Figure 1 In the embodiment of the present application, the concrete aggregate treatment device further comprises a second filter layer 620, which is located between the first filter layer 610 and the storage tank 100, and extends from the spraying area 200 to the storage area 220. The second filter layer 620 is a one-way filter layer, the passing direction of the second filter layer 620 is from top to bottom, and the filtering diameter of the second filter layer 620 is smaller than the filtering diameter of the first filter layer 610.

[0052] The first filter layer 610 and the second filter layer 620 have different filtration diameters, with the first filter layer 610 having a larger filtration diameter than the second filter layer 620. The first filter layer 610 filters larger aggregate particles that fall from the drain frame 500, while smaller aggregate particles, such as sand, pass through the first filter layer 610 and are filtered at the second filter layer 620. A settling zone is then formed between the first filter layer 610 and the second filter layer 620 to collect sand particles with a preset radius. The diameter of the sand collected in the settling zone can be set based on the filtration diameters of the first filter layer 610 and the second filter layer 620. For example, if it is necessary to collect sand particles with a diameter of 0.5mm-1mm, then the filtration diameter of the first filter layer 610 can be set to 1mm, and the filtration diameter of the second filter layer 620 can be set to 0.5mm.

[0053] In addition, once the sand collected in the settling area reaches a certain height, the first filter layer 610 can be opened to remove the collected sand, thus preventing the height of the sand in the settling area from exceeding that of the first filter layer 610.

[0054] Furthermore, in this embodiment, the second filter layer 620 can also be a unidirectional filter layer. For example, in this embodiment, the passing direction of the second filter layer 620 is... Figure 1 The filtration diameter shown from top to bottom is 1 μm. That is, particles with a diameter greater than 1 μm cannot pass through the second filtration layer 620 to enter the storage tank 100, while particles with a diameter less than 1 μm can pass through the second filtration layer 620 to enter the storage tank 100. However, the liquid in the storage tank 100 cannot pass through the second filtration layer 620 to enter the sedimentation zone.

[0055] like Figure 2 As shown in the embodiment of this application, the drain frame 500 includes a bottom plate 510 and two side plates 520. The two side plates 520 are disposed on opposite sides of the bottom plate 510, and the two side plates 520 are located on the same side of the bottom plate 510.

[0056] The base plate 510 has a mesh structure, with an opening at the top of the drain frame 500 in the vertical direction, and openings at both ends of the drain frame 500 along the extension direction of the conveyor belt 400.

[0057] Among them, such as Figure 2 As shown in Figure a, the base plate 510 of the drain frame 500 has a mesh structure to support the concrete aggregate to be treated. The size of the mesh on the base plate 510 can be determined based on the particle size of the concrete aggregate to be treated. For example, if it is used to support fine aggregate, the diameter of each mesh on the base plate 510 shall not exceed 0.075 mm; if it is used to support coarse aggregate, the diameter of the mesh on the base plate 510 shall not exceed 4.75 mm.

[0058] like Figure 2 As shown in b, a side plate 520 is provided on each of the opposite sides of the bottom plate 510 of the drain frame 500. The area between the side plates 520 and the bottom plate 510 forms a bearing area for bearing the concrete aggregate to be treated. Figure 2 In the indicated orientation, the lower ends of the two side plates 520 are connected to the base plate 510, and the upper ends form open openings to facilitate the entry of sprayed water and / or modifier into the bearing area. Additionally, as shown... Figure 1 As shown, along the traveling direction of the drain frame 500, both ends of the drain frame 500 are also set with openings to facilitate loading and unloading of concrete aggregates.

[0059] like Figure 1 As shown in the embodiments of this application, each of the drain frames 500 is mounted on the conveyor belt 400 via a pulley system;

[0060] Each of the pulley groups includes a first pulley 410 and a second pulley 420, both of which are attached to the conveyor belt 400 and can move with the conveyor belt 400.

[0061] Along the extension direction of the conveyor belt 400, both ends of any of the drain frames 500 are respectively suspended on the first pulley 410 and the second pulley 420 of their corresponding pulley groups.

[0062] Among them, such as Figure 1 As shown in the embodiments of this application, each pulley block may include at least two pulleys, the two pulleys being used to respectively suspend the drain frame 500 at both ends in its direction of travel. Figure 1 (At the left and right ends of the drain frame 500 in the indicated orientation), each pulley group is set on the conveyor belt 400 to follow the movement of the conveyor belt 400.

[0063] like Figure 1 As shown in this embodiment, the storage area 220 is provided with a discharge chute 230. Along the conveying direction of the conveyor belt 400, the discharge chute 230 extends from one end near the draining area 210 to the other end, and the height of the discharge chute 230 gradually decreases. Figure 1 In the orientation shown, the conveying direction of the drain frame 500 is from left to right. Therefore, the height of the material drop chute 230 gradually decreases from left to right. After the drain frame 500 travels above the material drop chute 230, the height of the right end of the drain frame 500 can be raised by the right pulley, or the height of the left end of the drain frame 500 can be lowered by the left pulley, so that the drain frame 500 is tilted and the concrete aggregate inside can slide down into the material drop chute 230 and then slide down along the material drop chute 230.

[0064] like Figure 1 As shown in this embodiment, in the horizontal direction, the end of the material discharge chute 230 away from the draining area 210 extends beyond the conveyor belt 400 to the farthest point within the storage area 220. Wherein, Figure 1 In the orientation shown, the right side of the discharge chute 230 is the end furthest from the draining area 210. The right end of the discharge chute 230 extends beyond the rightmost end of the conveyor belt 400. That is, when the draining frame 500 reaches the rightmost end of the conveyor belt 400 within the storage area 220, it is still located above the discharge chute 230, thus ensuring that the concrete aggregate in the draining frame 500 can fall into the discharge chute 230. Furthermore, in general, in the art, forklifts and other transport vehicles are mostly used to handle the concrete falling from the discharge chute 230. When transporting concrete aggregates, the working area of ​​the loader is generally located on the ground at the bottom of the discharge area of ​​the discharge chute 230. The bottom of the discharge chute 230 is the end of the discharge chute 230 away from the drain area 210. When the end of the discharge chute 230 away from the drain area 210 crosses the farthest point of the conveyor belt 400 extending into the storage area 220, the drain frame 500 cannot deliver the concrete to the discharge area at the bottom of the discharge chute 230, thus ensuring that the loader has sufficient working space.

[0065] like Figure 1 As shown in this embodiment, the conveyor belt 400 is a closed annular conveyor belt. The conveying path of the conveyor belt 400 sequentially passes through the spraying area 200, the draining area 210, and the storage area 220. By setting the conveyor belt 400 as a closed annular conveyor belt, multiple draining frames 500 can run on the conveyor belt 400 simultaneously. After each draining frame 500 is loaded with concrete aggregate to be processed, it first passes through the spraying area 200 for spraying, then through the draining area 210 for draining, and then enters the storage area 220 for unloading. After unloading, it continues to return along the closed annular conveyor belt, loads concrete aggregate to be processed, and continues the cycle. This cycle repeats continuously, which can improve processing efficiency.

[0066] In this embodiment, based on the concrete aggregate processing device described in the above embodiments, the concrete aggregate to be processed can be processed through the following steps:

[0067] First, load the concrete aggregate to be treated in the draining frame 500, start the drive pump, and the water and / or modifier in the storage pool rises along the water supply channel 300 to the spray head 310, falls back to the storage pool after being sprayed from the spray head 310, and the water and / or modifier starts to circulate along the storage pool, the water supply channel 300, and the spray head 310; start the conveyor belt 400, and convey the draining frame 500 along the conveyor belt 400 to below the spray head 310, spray each draining frame 500 for 20-30 minutes, then convey the draining frame 500 along the conveyor belt 400 to the draining area 210, and when there is no obvious water droplets falling from each draining frame 500, convey the draining frame 500 along the conveyor belt 400 to the storage area 220, adjust the height of the two ends of the draining frame 500 based on the pulley, unload the concrete aggregate in the draining frame 500 to the material falling chute 230 in the storage area 220 for storage, or for transport by a forklift.

[0068] In the embodiments of the present application, the water storage pool 100, the conveyor belt 400, the draining frame 500, the water supply channel 300, and the spray head 310 are arranged, and the spraying area 200 and the draining area 210 are arranged in the conveying path of the conveyor belt 400. When processing recycled concrete aggregate, the concrete aggregate to be treated is loaded in the draining frame 500, the draining frame 500 is conveyed along the conveyor belt 400 to the spraying area 200, and the draining frame 500 can be fully pre-absorbed with water and / or modifier through the spray head 310. After spraying, the draining frame 500 can continue to be conveyed by the conveyor belt 400 to the draining area 210 for draining, and the processing efficiency is high. In addition, the water and / or modifier in the spraying and draining processes can fall back to the water storage pool 100, so that the water and / or modifier can be reused, and the utilization rate of the water and / or modifier can be improved.

[0069] The above is only an optional embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structural transformation, direct / indirect application in other related technical fields based on the inventive concept of the present application, and the contents of the present application specification and drawings are included in the patent protection scope of the present application.
