DETAILED DESCRIPTION
[0028] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.
[0029] See also Figures 1 to 3The utility model provides a construction waste crushing and recycling device, including an outer box 100, a hammer box 200, a main material feeding mechanism 300, a hammer mechanism 400 and a screening plate 500.
[0030] Specifically, a fine slag outlet connected to the outside is provided at the bottom of the outer box 100, and a coarse slag outlet is provided at the side wall of the outer box 100. The hammer box 200 is arranged in the outer box 100, the inlet of the hammer box 200 extends to the outside of the outer box 100, and a discharge port is provided at the bottom of the hammer box 200; the main material feeding mechanism 300 is used to feed the construction waste soil from the inlet into the hammer box 200.
[0031] The hammer mechanism 400 is arranged in the hammer box 200, and is used to hammer and crush the construction waste soil entering the hammer box 200. The screening plate 500 is arranged in the outer box 100 and is located below the discharge port. The periphery of the screening plate 500 abuts against the inner wall of the outer box 100, and the end of the screening plate 500 close to the outer box 100 is flush with the coarse residue outlet.
[0032] When in use, the hammer mechanism 400 is started, and the construction waste soil is placed on the main material feeding mechanism 300. The main material feeding mechanism 300 inputs the material from the feeding port, and the hammer mechanism 400 hammers and crushes the waste soil. Since the internal hard stone aggregate is harder than the external concrete, the concrete is separated from the hard stone aggregate and crushed into small concrete particles by the hammering and crushing of the hammer mechanism 400. The separated hard stone aggregate and small concrete particles fall onto the screening plate 500 from the discharging port, and the smaller concrete particles flow out from the fine slag outlet through the screening plate 500, and the larger hard stone aggregate flows out from the coarse slag outlet.
[0033] Through the hammering and crushing of this device, the concrete and hard aggregate can be effectively separated, the hard aggregate can be effectively recycled, the waste of hard aggregate can be reduced, and thus the production cost can be saved.
[0034] In this embodiment, the hammering mechanism 400 includes a first rotating power source 410, a rotating cylinder 420 and a striking hammer 430. The rotating cylinder 420 is rotatably arranged in the hammering box 200, and the first rotating power source 410 is connected to the rotating cylinder 420 to drive the rotating cylinder 420 to rotate. There are multiple striking hammers 430, and the multiple striking hammers 430 are circumferentially spaced on the rotating cylinder 420. When the rotating cylinder 420 rotates, the striking hammers 430 can strike the materials entering from the feeding port. Specifically, the striking hammer 430 includes a hammer rod 431 and a hammer head 432. The hammer rod 431 is hinged to the rotating cylinder 420, and the hammer head 432 is fixed to the end of the hammer rod 431.
[0035] During use, when the first rotary power source 410 is started, the rotary cylinder 420 is driven to rotate, and the striking hammer 430 can be driven to hammer the material entering the hammer box 200.
[0036] As an effective implementation, the device further includes a circulating conveying mechanism 600. The circulating conveying mechanism 600 is arranged outside the outer box 100, and can receive the material flowing out of the coarse slag outlet, and can convey the material thereon to the feed inlet. When it is found that there is still a lot of hard stone aggregate with concrete attached to the surface of the material flowing out of the coarse slag outlet, the main material feeding mechanism 300 can be closed, and the circulating conveying mechanism 600 can be started, so that the material from the coarse slag outlet flow channel is input into the feed inlet again for hammering.
[0037] Specifically, the circulating conveying mechanism 600 includes an upward conveying structure 610 and a guide plate 620. The coarse slag outlet is arranged on the same side as the feed port. The guide plate 620 is arranged on the outer box 100 and connected to the feed port, and can guide the material into the feed port. The feed end of the upward conveying structure 610 is arranged below the coarse slag outlet, and the discharge end of the upward conveying structure 610 is arranged above the guide plate 620.
[0038] When in use, when the upward conveying structure 610 is started, the material flowing out of the coarse slag outlet can be conveyed upward to the guide plate 620 through the upward conveying structure 610, and then enter the hammer box 200 through the guide plate 620 for multiple hammer crushing until the requirements are met.
[0039] As another preferred embodiment, the device also includes a vibration mechanism 700. The screening plate 500 can be slidably connected to the inner wall of the outer box 100 up and down, and is placed on a limiting step provided on the inner wall of the outer box 100. The vibration mechanism 700 is arranged in the outer box 100 and connected to drive the screening plate 500 to vibrate up and down.
[0040] The vibration of the vibration mechanism 700 can not only increase the screening speed, but also reduce the probability of the screening holes being blocked.
[0041] Specifically, the vibration mechanism 700 includes a second rotational power source 710 and an eccentric cylinder 720. The eccentric cylinder 720 is rotatably arranged below the screening plate 500. During the rotation of the eccentric cylinder 720, the outer wall of the eccentric cylinder 720 can slide against the screening plate 500. The second rotational power source 710 is connected to the central axis of the eccentric cylinder 720 and can drive the eccentric cylinder 720 to rotate.
[0042] When in use, when the second rotating power source 710 is on, the eccentric cylinder 720 can push the screen plate 500 to move upward. Under the weight of the screen plate 500, the push of the eccentric cylinder 720 and the impact of the material coming out of the discharge port, the screen plate 500 can be vibrated up and down.
[0043] As a more preferred embodiment, the vibration mechanism 700 further includes an elastic support member 730, and the screening plate 500 is supported on the limiting step by the elastic support member 730. The elastic support member 730 further improves the vibration effect.
[0044] In this embodiment, the feed inlet is covered with a blocking curtain 800, the top of the blocking curtain 800 is arranged with the upper wall of the feed inlet, and the lower end of the blocking curtain 800 can move freely. In addition, the blocking curtain 800 can prevent the material in the hammer box 200 from splashing outward. In addition, a plurality of raised blocks 900 can be arranged at intervals on the inner wall of the hammer box 200 to further improve the hammering effect.
[0045] It should be noted that, in the present embodiment, the first rotating power source 410 and the second rotating power source 710 may be rotating motors commonly used in the current technology. Of course, other mechanisms that can drive an object to rotate may also be used.
[0046] The usage of the above-mentioned construction waste crushing and recycling device is as follows:
[0047] When in use, the first rotary power source 410 and the second rotary power source 710 are started, and the construction waste soil is placed in the main material feeding mechanism 300, and the main material feeding mechanism 300 inputs the material from the feeding port, and the hammering mechanism 400 crushes the waste soil. Since the internal hard stone aggregate is harder than the external concrete, the concrete is separated from the hard stone aggregate and crushed into small concrete particles through the hammering and crushing of the hammering mechanism 400. The separated hard stone aggregate and small concrete particles fall onto the screening plate 500 from the discharge port, and the smaller concrete particles flow out from the fine slag outlet through the screening plate 500, and the larger hard stone aggregate flows out from the coarse slag outlet.
[0048] When it is found that there is still a lot of hard stone aggregate with concrete attached to the surface of the material flowing out of the coarse slag outlet, the main material feeding mechanism 300 can be closed and the circulation conveying mechanism 600 can be started to allow the material from the coarse slag outlet flow channel to be input into the feed port again for hammering.
[0049] The above-mentioned construction waste crushing and recycling device can effectively separate concrete and hard aggregate, realize effective recycling of hard aggregate, reduce waste of hard aggregate, and thus save production costs. The material from the coarse slag outlet flow channel can be hammered by the circulating conveying mechanism 600, and the vibration of the vibration mechanism 700 can not only increase the screening speed, but also reduce the probability of the screening hole being blocked.
