Description

Technical Field

[0001] The present invention relates to the field of construction waste treatment equipment, in particular to construction solid waste recycling equipment. Background Art

[0002] In the process of demolition, construction, decoration, repair and other production activities of buildings, various types of construction waste are bound to appear, among which solid construction waste is the main one, especially reinforced concrete. Due to its high strength and large volume, it is very difficult to handle. Some large reinforced concrete with thicker diameter steel bars inside is generally crushed by various crushers, breakers, etc. to remove the concrete and recycle the steel bars with higher value. However, this method is expensive. For walls with thinner diameters such as tie bars mixed in the middle, it is extremely wasteful to use the above-mentioned crushing method, which consumes a lot of fuel, labor, and engineering vehicles and machinery.

[0003] The general diameter of the tie bar is 6mm, and due to its location, there is usually rust on the surface. In the process of treating the solid waste of the wall with tie bars, even if the recycling can be completed, the rust on the surface still needs to be treated again. There is no good way to completely remove the wall concrete and rust at the same time as separating these steel bars. At the same time, when crushing concrete, two types of solid waste, powder and block, will be produced at the same time. The powder can be directly recycled, but dust reduction operations are required, and the block may need to be crushed again. Therefore, the two types of solid waste need to be separated again, and the process is also very troublesome. Summary of the Invention

[0004] The purpose of the present invention is to provide a construction solid waste recycling device to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: A construction solid waste recycling device, comprising a cutting device, a crushing and separating device, and a recycling device, wherein the cutting device is provided with staggered and oppositely rotating cutting discs, the cutting discs being installed in a rectangular frame, the rectangular frame being installed on the top of the crushing drum of the crushing and separating device, a crushing roller being provided in the crushing drum, the crushing roller crushing concrete mixed with tie bars by high-speed rotation, a discharge port being provided on the side of the crushing drum, a recycling device being provided below the discharge port, the recycling device and the crushing and separating device being both installed on a bracket, a recycling cylinder being provided in the recycling device, a pushing plate being provided in the recycling cylinder, the steel bars discharged through the discharge port falling into the recycling cylinder and being pushed to one end of the recycling cylinder by the pushing plate, an elastic bag being connected to the other end of the recycling cylinder, a water outlet and a water inlet being provided on the elastic bag, the water outlet being connected to the water inlet pipe on the cutting device, the water inlet pipe being provided with a nozzle, and the water inlet being connected to an external water source.

The other end of the recovery cylinder 31 is connected to an elastic bag 5, and the elastic bag 5 is provided with a water outlet 51 and a water inlet 52. The water outlet 51 is connected to the water inlet pipe 6 on the cutting device 1, and the water inlet pipe 6 is provided with a nozzle 7. The water inlet nozzle 52 is connected to an external water source. When the elastic bag 5 is under pressure, water is sprayed from the nozzle 7 through the connected water source to form intermittent water mist, thereby reducing dust when cutting concrete.

[0033] In this embodiment, the cutting disc 11 is provided with a cutting edge, and the cutting edge is provided with a cutting blade 111 for cutting. The two sets of cutting discs 11 rotating in opposite directions are respectively installed on the driving shaft 14 and the driven shaft 15. The ends of the driving shaft 41 and the driven shaft 15 are provided with a transmission gear set 16, and the transmission gear set 16 is driven by a motor 17. The motor 17 is installed on the motor bracket. The equidistantly arranged cutting discs 11 can divide the placed concrete blocks into blocks of uniform thickness, which is convenient for subsequent crushing, and the spacing between the cutting discs 11 can ensure that the tie bars in the concrete can be kept to a certain length even if they are cut, thereby preventing the production of shorter tie bars.

[0034] In the embodiment, the rectangular frame 12 is provided with a water storage tank 121, the water storage tank 121 is provided with a water inlet pipe 6 on the side, and the nozzle 7 is arranged on the top surface of the water storage tank 121 and connected with the water outlet nozzle 51 through the water inlet pipe 6. The water outlet nozzle 51 is a one-way water nozzle for ensuring that water cannot flow back, and the water mist sprayed from the nozzle 7 can play a role in dust reduction.

[0035] In the embodiment, the bottom of the crushing cylinder 21 is provided with a screen 211, the screen 211 is provided with 2-3 layers of mesh sizes increasing from top to bottom, the crushed concrete particles have different particle sizes, which can better facilitate the adjustment of particle grading in the later stage and optimize the use in mixing new concrete, the area ratio of the screen 211 to the cylinder wall of the crushing cylinder 21 is 1:3-4, the screen 211 is located at the bottom of the crushing cylinder 21, which can screen the crushed blocky concrete, and the remaining side walls of the crushing cylinder 21 are provided with reinforced impact plates to help crushing the concrete.

[0036] In the embodiment, the crushing roller 22 is provided with a crushing knife 221, the crushing knife 221 is spirally distributed on the crushing roller 22, both ends of the crushing roller 22 are installed on the crushing cylinder 21 through flanges, one end of the crushing roller 22 is connected to the motor two 223, and the motor two 223 is installed on the motor support. When the crushing knife 221 rotates at high speed, it will crush and drive the concrete to impact on the side wall of the crushing cylinder 21 through its own impact force, helping the concrete to be quickly crushed, and the rust on the surface of the tie bar will be removed through the impact and friction between the concrete and the tie bar during the rotation process, so that the rust falls off and becomes powdery. At the same time, water will flow down in the cutting device above, the water and the powdery concrete combine to form a mixture with adsorption effect, the powdery rust removed will be adsorbed by the mixture and form a group, which will move to the direction of the discharge port 23 under the pushing action of the spirally arranged crushing knife 221 and finally be discharged.

[0037] In the embodiment, the discharge port 23 is provided with a cover plate 24 for plugging, the cover plate 24 is rotatably installed on the flange of the crushing roller 22, and the cover plate 24 is provided with a gear 25. When the gear 25 is pushed, the cover plate 24 rotates with the gear 25, so that the discharge port 23 is no longer covered during rotation, and the tie bar and the mixture mixed with rust at the discharge port 23 are discharged.

[0038] In the embodiment, the pushing plate 32 is connected with a connecting rod 34, the top of the connecting rod 34 is connected with the output shaft of a hydraulic cylinder 35, the hydraulic cylinder 35 is installed on a bottom plate 351, the bottom plate 351 is fixed on the recovery cylinder 31, the pushing plate 32 is driven by the hydraulic cylinder 35 to move back and forth in the recovery cylinder 31, and the tie bars and the mixture mixed with rust falling in the recovery cylinder 31 are pushed out.

[0039] In the embodiment, the side wall of the recovery cylinder 31 below the discharge port 23 is provided with a guide plate 311, the bottom of the end surface of the recovery cylinder 31 is provided with a discharge port 312, the side surface of the connecting rod 34 is provided with a rack 341, the rack 341 is engaged with the gear 25, when the rack 341 moves from the side where the elastic bag 5 is arranged to the side where the discharge port 312 is arranged, that is, the pushing plate 32 moves to the side of the discharge port 312, the rack 341 drives the gear 25 to rotate, that is, the cover plate 24 is driven to rotate, and the discharge port 23 is re-blocked when rotating, so that the tie bars and other objects in the crushing cylinder 23 are not discharged, at the same time, the tie bars and other objects falling in the recovery cylinder 31 are pushed to the discharge port 312 by the pushing plate 32, at this time, the elastic bag 5 is driven by the pushing plate 32 to relax, because the water outlet 51 and the water inlet 52 are one-way water nozzles, the elastic bag 5 absorbs water from the external water source; when the pushing plate 32 moves to the side of the elastic bag 5, the rack 341 drives the cover plate 24 to rotate, the discharge port 23 is opened, the tie bars and other objects in the crushing cylinder 21 fall in the recovery cylinder 31, at the same time, the elastic bag 5 is compressed, the water in the elastic bag 5 enters the water storage tank 121 through the water outlet 51 and is finally sprayed out of the nozzle 7, and then the above two processes are sequentially and cyclically performed.

[0040] Working principle: When in use, first turn on motor 17 and motor 2 223, then put the large piece of concrete onto the cutting disc 11, and cut it into blocks with relatively uniform thickness. The spacing between the cutting discs 11 can ensure that the tie bars in the concrete can be kept to a certain length even if they are cut, to prevent the generation of shorter tie bars. At this time, water mist is sprayed from the nozzle 7 to achieve the purpose of dust reduction. Then the cut concrete falls into the crushing drum 21. When the crushing knife 221 rotates at high speed, it will crush it through its own impact force and drive the concrete to hit the side wall of the crushing drum 21, helping the concrete to be crushed quickly. In the process of this driving rotation, because the tie bars are steel bars, they have high strength and will not break due to the impact. In addition, in the process of this rotation, the rust on the surface of the tie bars will be removed through the collision and friction between the concrete and the tie bars, so that the rust will fall off and become powder. At the same time, water will flow down from the cutting device above, and the water will combine with the powdered concrete to form a mixture with an adsorption effect. The removed powdered rust will be adsorbed by this mixture and agglomerated. Under the push of the rotating crushing knife 221, it moves toward the discharge port 23 and accumulates at the discharge port 23. At this time, due to the continuous circulation of the hydraulic cylinder 35, the rack 341 pushes the gear 25 to rotate, that is, it drives the cover plate 24 to rotate, and when it rotates, it will block the discharge port 23 again, and the tie bars and other objects in the crushing cylinder 23 will no longer be discharged. At the same time, the tie bars and other objects that fall into the recovery cylinder 31 will be pushed to the discharge port 312 by the pushing plate 32 for discharge. At this time, the elastic bag 5 is driven to expand by the pushing plate 32. Since the water outlet 51 is connected to the water outlet 51, the elastic bag 5 is pulled back. The water inlet nozzles 52 are all one-way water nozzles, so the elastic bag 5 will absorb water from the external water source; and when the push plate 32 moves toward the side of the elastic bag 5, the rack 341 drives the cover plate 24 to rotate, the discharge port 23 opens, and the tie bars and other materials in the crushing cylinder 21 fall into the recovery cylinder 31. At the same time, the elastic bag 5 is compressed, and the water therein will enter the water storage tank 121 through the water outlet nozzle 51 and finally be sprayed out from the nozzle 7, so that the concrete with tie bars can be processed and the tie bars therein can be recovered. At the same time, a part of the concrete blocks can also be recovered.

[0041] Based on the above, the water sprayed from the nozzle in this invention will fall into the crushing drum. When the crushing knife crushes the concrete, the powdered concrete mixes with water to form a sticky mixture. When the crushing roller rotates at a high speed, the rust falling off the tie bar will be absorbed by the above sticky mixture, helping to remove the rust on the steel bar. In this invention, the clumped sticky mixture and the peeled tie bar will be discharged from the crushing drum through the spirally arranged crushing knife, and the crushed larger pieces of concrete will be discharged from the screen, so that the powdered and block concrete can be discharged separately.

[0042] It is apparent that the application can be carried out by other embodiments that do not depart from the spirit or essential characteristics thereof. Thus, the embodiments disclosed in this specification are to be considered in all respects as illustrative and not restrictive, and all changes coming within the meaning and equivalency range of the application are intended to be embraced therein.
