Description

Technical Field

[0001] This utility model relates to the field of recycled aggregates, and in particular to a recycled aggregate screening device. Background Technology

[0002] The preparation of recycled aggregates from construction waste is currently a key focus of research on the recycling of construction waste. With the increasing awareness of sustainable development and the development of science and technology, more and more solid wastes can be recycled, most of which become recycled aggregates. In order to improve the purity of recycled aggregates and separate impurities such as mud from the aggregates, some manufacturers currently use recycled aggregate roller screens to screen the recycled aggregates.

[0003] Currently, some recycled aggregate roller screen structures still have certain problems in use: Many recycled aggregate roller screens on the market are directly installed on construction waste sites, and workers drive excavators to dump construction waste into the hopper of the roller screen. Several sets of rollers move the construction waste forward. During the process, impurities that do not meet the requirements will fall through the gaps between the rollers, while the larger materials that meet the requirements will move along the rollers to the designated area. In order to facilitate the subsequent maintenance and cleaning of the rollers, the roller screen is often directly exposed to the external environment. Due to the lack of good protection, the construction waste on the roller screen can easily raise a lot of dust as it rolls forward, which will fly directly outside the device, causing a lot of inconvenience to the people working in the nearby area.

[0004] Therefore, it is necessary to provide a new recycled aggregate screening device to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a recycled aggregate screening device that can greatly reduce the dust problem generated during the screening of construction waste.

[0006] To solve the above-mentioned technical problems, the present invention provides a recycled aggregate screening device comprising: a frame, a first dustproof component, and a second dustproof component. The frame is provided with several sets of screening components inside, and a conveying structure is provided inside the frame located below the screening components. A hopper is fixedly connected to one side edge of the top of the frame. The first dustproof component includes a top cover, which is located on one side of the hopper and is hinged to one side edge of the top of the frame. A support member is fixedly connected to one side wall surface of the frame. Two support members are provided on the surface of the frame, and an electric telescopic rod is hinged between the top of each of the two support members and the upper surface of the top cover.

[0007] The second dustproof component includes a second pipe, which is arranged along the outside of the hopper and fixedly connected to the outer wall of the hopper via a connecting block. Several evenly distributed atomizing nozzles are installed on the top of the second pipe, and the second pipe is connected to a communicating vessel via a connecting pipe.

[0008] As a further embodiment of this utility model, the screening assembly includes rollers, which are rotatably connected to the inner wall of the frame and are arranged in a plurality of rollers inside the frame. One end of each of the plurality of rollers passes through the surface of the frame and is fixedly connected to a sprocket. The plurality of sprockets are connected to each other by a chain. A drive motor is fixedly connected to the frame surface on one side relative to the chain, and the output end of the drive motor is fixedly connected to the end of one side of the roller.

[0009] Through the above technical solution, the roller surface of the recycled aggregate roller screen used in the market is provided with many protrusions. This is to make it easier for construction waste to be dispersed and screened during the rolling process. In addition, the rollers in the device are grouped into several groups, and the rollers are driven to rotate by a drive motor and transmitted by a chain and sprocket.

[0010] As a further embodiment of this utility model, a guide plate is fixedly connected to the side wall surface of the frame on one side of the hopper, and a first pipe is provided on both sides of the guide plate. Several evenly distributed flushing nozzles are installed on the surface of the first pipe, and the first pipe is connected to a communicating vessel through a connecting pipe.

[0011] With the above technical solution, when the device is in use, it is set up in a suitable location on the construction waste site. Then, an excavator can be used to dump the construction waste into the hopper. At this time, due to the movement of the excavator, a lot of dust is easily generated near the hopper. At this time, the water pump is started to draw external water to supply water to the second pipe. The atomizing nozzles on the second pipe can spray water mist to target the dust in the special area with severe dust. The structural design can save resources and greatly reduce dust. After the construction waste is screened by the roller and discharged onto the guide plate, large pieces of stone are prone to generating some dust and other impurities due to rolling and falling. Therefore, the structure is equipped with a first pipe on both sides of the guide plate. The water pump draws external water to supply water to several flushing nozzles to wet the surface of the stone and prevent workers from inhaling too much dust when processing the screened stone.

[0012] As a further embodiment of this utility model, the communicating vessel is fixedly connected to the surface of the frame via a connecting block, and a water pump is connected to the communicating vessel via a pipe. The input end of the water pump is connected to an external water source via a pipe.

[0013] With the above technical solution, both the first and second pipes in the structure are connected to the communicating vessel, while the input end of the water pump needs to be connected to an external water source, so as to provide sufficient water for each nozzle.

[0014] As a further embodiment of this utility model, a baffle is fixedly connected to the surface of the top cover facing the hopper, and an opening is provided on the surface of the hopper facing the top cover, with the baffle and the opening matching each other.

[0015] Through the above technical solution, in traditional structures, in order to facilitate subsequent maintenance and cleaning of the rollers, the roller screen is mostly directly exposed to the external environment. Due to the lack of good protection, the construction waste on the roller screen easily raises a lot of dust as it rolls forward, and the dust flies directly outside the device, causing a lot of inconvenience to the workers in the nearby area. Therefore, this device adds a top cover to the top area of ​​the frame. The top cover is equipped with an electric telescopic rod, which can be quickly opened when workers are cleaning and maintaining it. When the rollers are working normally, the top cover is in a closed state, thereby effectively reducing the inconvenience caused by dust to the workers in the nearby area.

[0016] As a further embodiment of this utility model, the conveying structure includes two rotating rollers, which are rotatably connected to both ends of the frame respectively. A conveyor belt is connected between the two rotating rollers. A rotary motor is fixedly connected to one side wall surface of the frame, and the output end of the rotary motor is fixedly connected to the end of one rotating roller.

[0017] With the above technical solution, there are gaps between the rollers. When construction waste rolls on the rollers, smaller impurities will pass through the gaps and fall onto the conveyor belt on the underside of the rollers, and then be transported to other places for separate processing.

[0018] As a further embodiment of this utility model, the conveyor belt is located below several rollers, and the output end of the first pipe surface rinsing nozzle faces the surface of the guide plate.

[0019] With the above technical solution, the conveyor belt is set under the roller to receive the impurities screened out by the roller, while the flushing nozzles facing the guide plate can suppress dust in the outlet area of ​​the frame.

[0020] Compared with related technologies, the recycled aggregate screening device provided by this utility model has the following advantages:

[0021] 1. In this utility model, when the device is in use, it is set up in a suitable position on the construction waste site. Then, an excavator can be used to dump the construction waste into the hopper. At this time, due to the movement of the excavator, a lot of dust is easily generated near the hopper. At this time, the water pump is started to draw external water to supply water to the second pipe. The atomizing nozzles on the second pipe can spray water mist to target the dust in the special area with serious dust. The structural design can save resources and greatly reduce dust. After the construction waste is screened by the roller and discharged onto the guide plate, large pieces of stone are prone to generating a certain amount of dust and impurities due to rolling and falling. Therefore, the structure is equipped with a first pipe on both sides of the guide plate. The water pump draws external water to supply water to several flushing nozzles to wet the surface of the stone and prevent workers from inhaling a lot of dust when processing the screened stone.

[0022] 2. In this utility model, in the traditional structure, in order to facilitate the subsequent maintenance and cleaning of the rollers by workers, the roller screen is mostly directly exposed to the external environment. Due to the lack of good protection, the construction waste on the roller screen is prone to raising a lot of dust as it rolls forward, and it flies directly outside the device, causing a lot of inconvenience to the workers in the nearby area. Therefore, this device adds a top cover to the top area of ​​the frame. The top cover is equipped with an electric telescopic rod, which can be quickly opened when workers clean and maintain it. When the rollers are working normally, the top cover is in a closed state, thereby effectively reducing the inconvenience caused by dust to the workers in the nearby area.

[0030] Please combine Figures 1 to 4 ,in, Figure 1 This is a schematic diagram of the overall structure of a recycled aggregate screening device according to the present invention. Figure 1 ; Figure 2 This is a schematic diagram of the overall structure of a recycled aggregate screening device according to the present invention. Figure 2 ; Figure 3 This is a schematic diagram of the overall structure of a recycled aggregate screening device according to the present invention. Figure 3 ; Figure 4 This is a partial structural diagram of a recycled aggregate screening device according to the present invention. The recycled aggregate screening device includes:

[0031] The machine includes a frame 1, a first dustproof component 2, and a second dustproof component 3. The machine frame 1 is equipped with several sets of screening components 8. The machine frame 1 located below the screening components 8 is equipped with a conveying structure 10. A hopper 4 is fixedly connected to one side edge of the top of the machine frame 1. The first dustproof component 2 includes a top cover 13. The top cover 13 is located on one side of the hopper 4 and is hinged to one side edge of the top of the machine frame 1. A support member 14 is fixedly connected to one side wall surface of the machine frame 1. There are two support members 14 on the surface of the machine frame 1. An electric telescopic rod 5 is hinged between the top of the two support members 14 and the upper surface of the top cover 13.

[0032] The second dustproof component 3 includes a second pipe 20, which is arranged along the outside of the hopper 4 and fixedly connected to the outer wall of the hopper 4 through a connecting block. Several evenly distributed atomizing nozzles 21 are installed on the top of the second pipe 20, and the second pipe 20 is connected to a communicating vessel 6 through a connecting pipe.

[0033] like Figure 1-4 As shown, the screening assembly 8 includes rollers 22, which are rotatably connected to the inner wall of the frame 1. Several rollers 22 are located inside the frame 1. One end of each roller 22 passes through the surface of the frame 1 and is fixedly connected to a sprocket 11. The sprockets 11 are connected to each other by a chain 12. A drive motor is fixedly connected to the surface of the frame 1 on one side of the chain 12. The output end of the drive motor is fixedly connected to the end of one side of the roller 22.

[0034] The rollers 22 of the recycled aggregate roller screens used in the market are all provided with many protrusions. This is to make it easier for construction waste to be dispersed and screened during the rolling process. In this device, several rollers 22 are grouped together. The rollers 22 are driven to rotate by a drive motor and are transmitted by a chain 12 and a sprocket 11.

[0035] like Figure 1-4 As shown, a guide plate 9 is fixedly connected to the side wall surface of the frame 1 relative to the hopper 4. A first pipe 18 is provided on both sides of the guide plate 9. Several evenly distributed flushing nozzles 19 are installed on the surface of the first pipe 18. The first pipe 18 is connected to the communicating vessel 6 through a connecting pipe.

[0036] When in use, the device is set up in a suitable location on the construction waste site. Then, an excavator can be used to dump the construction waste into the hopper 4. At this time, due to the movement of the excavator, a lot of dust is easily generated near the hopper 4. At this time, the water pump 7 is started to draw external water to supply water to the second pipe 20. The atomizing nozzles 21 on the second pipe 20 can spray water mist to target the dust in the special area with severe dust. The structural design can save resources and greatly reduce dust. After the construction waste is screened by the roller 22 and discharged onto the guide plate 9, large pieces of stone are prone to generating some dust and other impurities due to rolling and falling. Therefore, the structure is equipped with first pipes 18 on both sides of the guide plate 9. The water pump 7 draws external water to supply water to several rinsing nozzles 19 to wet the surface of the stone and prevent workers from inhaling too much dust when processing the screened stone.

[0037] like Figure 1-4 As shown, the communicating vessel 6 is fixedly connected to the surface of the frame 1 via a connecting block, and the communicating vessel 6 is connected to a water pump 7 via a pipe. The input end of the water pump 7 is connected to an external water source via a pipe.

[0038] In the structure, the first pipe 18 and the second pipe 20 are both connected to the communicating vessel 6, while the input end of the water pump 7 needs to be connected to an external water source to provide sufficient water for each nozzle.

[0039] like Figure 1-4 As shown, a baffle 15 is fixedly connected to the surface of the top cover 13 facing the hopper 4, and an opening is provided on the surface of the hopper 4 facing the top cover 13, with the baffle 15 matching the opening.

[0040] In traditional structures, to facilitate subsequent maintenance and cleaning of the rollers 22, the roller 22 screen is often directly exposed to the external environment. Due to the lack of good protection, the construction waste on the roller 22 screen easily raises a large amount of dust as it rolls forward, which is directly blown outside the device, causing a lot of inconvenience to the workers in the nearby area. Therefore, this device adds a top cover 13 to the top area of ​​the frame 1. The top cover 13 is equipped with an electric telescopic rod 5, which can be quickly opened when workers are cleaning and maintaining it. When the rollers 22 are working, the top cover 13 is in a closed state, thereby effectively reducing the inconvenience caused by dust to the workers in the nearby area.

[0041] like Figure 1-4 As shown, the conveying structure 10 includes two rotating rollers 17, which are rotatably connected to both ends of the frame 1 respectively. A conveyor belt 16 is connected between the two rotating rollers 17. A rotary motor is fixedly connected to one side wall surface of the frame 1, and the output end of the rotary motor is fixedly connected to the end of one rotating roller 17.

[0042] There are gaps between the rollers 22. When construction waste rolls on the rollers 22, smaller impurities will pass through the gaps and fall onto the conveyor belt 16 on the lower side of the rollers 22, and then be transported to other places for separate processing.

[0043] like Figure 1-4 As shown, the conveyor belt 16 is located below a plurality of rollers 22, and the output end of the surface rinsing nozzle 19 of the first pipe 18 faces the surface of the guide plate 9.

[0044] The conveyor belt 16 is located below the roller 22 to receive the impurities screened out by the roller 22, while the flushing nozzles 19 face the guide plate 9 to suppress dust in the outlet area of ​​the frame 1.

[0045] The working principle of the recycled aggregate screening device provided by this utility model is as follows:

[0046] First step: When using this device, it is set up in a suitable position on the construction waste site. Then, an excavator can be used to dump the construction waste into the hopper 4. At this time, due to the movement of the excavator, a lot of dust is easily generated near the hopper 4. At this time, the water pump 7 is started to draw external water to supply water to the second pipe 20. The atomizing nozzle 21 on the second pipe 20 can spray water mist to target the dust in the special area with serious dust. The structural design can save resources and greatly reduce dust. After the construction waste is screened by the roller 22 and discharged onto the guide plate 9, large pieces of stone are prone to generate a certain amount of dust and impurities due to rolling and falling. Therefore, the structure is equipped with first pipes 18 on both sides of the guide plate 9. The water pump 7 draws external water to supply water to several flushing nozzles 19 to wet the surface of the stone and prevent workers from inhaling a lot of dust when processing the screened stone.

[0047] The second step: In the traditional structure, in order to facilitate the subsequent maintenance and cleaning of the roller 22, the roller 22 screen is mostly directly exposed to the external environment. Due to the lack of good protection, the construction waste on the roller 22 screen is prone to raising a lot of dust as it rolls forward, and it flies directly outside the device, causing a lot of inconvenience to the workers in the nearby area. Therefore, the device adds a top cover 13 to the top area of ​​the frame 1. The top cover 13 is equipped with an electric telescopic rod 5, which can be quickly opened when the workers clean and maintain it. When the roller 22 is working, the top cover 13 is in a closed state, thereby effectively reducing the inconvenience caused by dust to the workers in the nearby area.
