Description

Technical Field

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

[0002] With the progress of urbanization, some old communities in the city center are also being renovated simultaneously. Some of the old communities were built earlier and still have relatively traditional brick-concrete structures. The demolition of these communities will also generate a large amount of construction waste. Unlike the demolition of some modern buildings, the demolition of these old communities generally does not contain concrete with a large amount of steel bars. Usually only some beams and columns contain steel materials such as tie bars, angle steels, and nails. Therefore, the cost of crushing and recovering the higher-value steel bars through various crushers, breakers, etc. is relatively high.

[0003] The waste generated by these brick-concrete buildings is generally made into recycled bricks or aggregates for reuse. This process requires the waste to be crushed, but the smaller materials such as tie bars and angle steels need to be separated. The separation process requires stopping the crushing equipment and taking out the materials that cannot be crushed. The starting and stopping of these engineering equipment will waste a lot of time and energy.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] See also Figures 1 to 8 The present invention provides a technical solution: a construction waste treatment device, comprising a treatment part and a power part, wherein the treatment part comprises an outer box 1, a crushing and separation device 2 and a recovery device 3, wherein the crushing and separation device 2 is arranged in the outer box 1, and the recovery device 3 is arranged below the outer box 1 and is located directly below the crushing and separation device 2, and the crushing and separation device is used to crush waste;

An impact plate 14 is provided on the upper side of the inner part of the outer box shell 13. The guide plate 12 can guide the input waste to the crushing and separation device 2 for crushing, and the impact plate 14 crushes the waste by impact.

[0043] In this embodiment, the direction of the guide plate 12 is the same as the rotation direction of the crushing and separating device 2, so as to prevent the rapidly rotating crushing and separating device 2 from throwing out the input waste materials and causing injuries.

[0044] In this embodiment, both ends of the stepped shaft 24 are rotatably mounted on the outer box 1, the crushing knife 21 and the toggle plate 22 are spaced apart from each other, and the end of the toggle plate 22 is provided with a forward curved arc, which can better throw up large pieces of waste.

[0045] In this embodiment, a screen 5 is provided in the outer box 1, and the screen 5 is fixedly installed below the crushing and separation device 2 and semi-enclosed on the outside of the crushing and separation device 2.

[0046] In this embodiment, the opening part 31 includes a baffle 311, an air circuit plate 312, a fixing plate 313 and a wear-resistant plate 314, the baffle 311 is fixedly installed on the top of the air circuit plate 312, the air circuit plate 312 and the fixing plate 313 are vertically arranged side by side and are both fixedly installed on the outer box 1, a recovery channel is provided between the air circuit plate 312 and the fixing plate 313, the baffle 311 covers the top of the recovery channel, an air circuit is provided in the air circuit plate 312, and the lower part of the air circuit is connected to the air pipe 315, the wear-resistant plate 314 is fixedly installed in the arc groove below the air circuit plate 312 and the fixing plate 313, the baffle 311, the air circuit plate 312 and the fixing plate 313 are all made of non-magnetic materials, and intermittent airflow is sprayed toward the opening position from the air circuit plate 312, and by changing the intensity of the airflow, the dust particles are subjected to a greater impact force, thereby preventing the dust from entering the opening and blocking the recovery channel.

[0047] In this embodiment, the magnetic suction part 32 includes an adsorption cylinder 321 and a magnetic suction rod 322. The adsorption cylinder 321 is coaxially arranged with the arc groove. The adsorption cylinder 321 is provided with an adsorption groove 323. A ball 324 is provided in the adsorption groove 323. An elastic pad 325 is provided under the ball 324. The ball 324 can be attracted by magnetic force. One end of the two ends of the magnetic suction rod 322 is fixedly connected to the flange, and the other end is rotatably connected to the adsorption cylinder 321. The magnetic suction rod 322 is provided with an electromagnet 326, and the electromagnet 326 is arranged The upper part of the magnetic suction rod 322 is set at an angle of 60°-90°, so that the top suction tube 321 is magnetic, while the lower suction tube 321 is not magnetic. At the same time, it will absorb the pin 324 close to the electromagnet 326, so that the pin compresses the elastic pad 325, and then no pin 324 floats out of the suction groove 323, so that the suction tube 321 can absorb the steel in the suction groove 323. When the suction groove 323 rotates to a place away from the electromagnet 326, the pin 324 and gravity will cause the adsorbed steel to fall off for easy recovery.

[0048] In this embodiment, an extension rod is provided at one end of the adsorption cylinder 321 , and the extension rod is rotatably connected to the flange and connected to the power part. The extension rod can be driven by the motor 4 to rotate intermittently.

[0049] In this embodiment, the power part also includes a pulley group 41, a second motor 42 and a piston cylinder 43. The output shaft of the motor 4 is connected to the step shaft 24. One end of the pulley group 41 is connected to the step shaft 24, and the other end is connected to the extension rod and is provided with a spacing structure 46 inside. The output shaft of the second motor 42 is provided with a lever column 44 and a crank structure 45. The lever column 44 can drive the spacing structure 46 when rotating. The end of the crank structure 45 is connected to the piston cylinder 43. The piston cylinder 43 is connected to the air pipe 315 through a pipeline. The motor 4 drives the step shaft 24 to rotate, so as to realize the rotation of the crushing knife 21 and the toggle plate 22. At the same time, the step shaft 24 drives the extension rod to rotate through the pulley group 41, and the second motor 42 drives the crank structure 45 to operate, pushing the piston cylinder 43 to intermittently blow air into the air pipe 315. An air inlet is provided on the piston cylinder 43, and a one-way valve is provided on the air inlet and the air pipe 315 to ensure the correct circulation of air.

[0050] In this embodiment, the spacing structure 46 includes a force plate 461, a conical disk 462, a friction pad 1 463 and a friction pad 2 464. The force plate 461 is welded and fixed to the conical disk 462 and connected to the extension rod through a key. The friction pad 1 463 is fixedly mounted on the conical disk 462, and the friction pad 2 464 is fixedly mounted on the connecting disk 465. The connecting disk 465 is mounted on the extension rod through a bearing. The outer side of the connecting disk 465 is connected to the pulley. Since the connection between the connecting disk 465 and the extension rod A bearing is provided, so during the rotation of the pulley group 41, the extension rod will not be driven to rotate through the pulley group 41. Only when the lever on the toggle column 44 presses down the force plate 461 and the conical disk 462 to make the friction pad 1 463 and the friction pad 2 464 frictionally contact, will the conical disk 462 and the force plate 461 be driven to rotate through friction, and then the extension rod will be driven to rotate. Such intermittent rotation can prevent the centrifugal force generated by continuous rotation from causing the adsorbed steel to fall off, and prevent excessively fast rotation from affecting the normal falling of the steel.

[0051] Working principle: When in use, first turn on the motor 4 to drive the stepped shaft 24 to rotate, so as to realize the rotation of the crushing knife 21 and the toggle plate 22. The crushing knife 21 can cut large pieces of waste through high-speed rotation and the cutting edge at the front end. At the same time, the high-speed rotating toggle plate 22 can throw and squeeze the incoming waste onto the impact plate 14 for crushing, and can also bring up the large pieces of waste through rotation and throw them back onto the impact plate 14 for crushing again. At the same time, the small steel materials such as tie bars, nails, etc. exposed after crushing will be attracted by the magnetic force of the electromagnet 326 during rotation, enter the recovery channel, and be adsorbed by the adsorption cylinder 3 21 and the adsorption groove 323 adsorb. When the adsorption groove 323 rotates to a position away from the electromagnet 326, the adsorbed steel will fall off through the ball 324 and gravity to complete the recovery. At the same time, the air circuit plate 312 intermittently blows out air flow to prevent dust from accumulating in the recovery channel. When the air circuit plate 312 blows out air flow, the lever on the toggle column 44 presses down the force plate 461 and the conical disk 462 to make the friction pad 1 463 and the friction pad 2 464 in friction contact, so that the conical disk 462 and the force plate 461 will be driven to rotate through friction, and then the extension rod will be driven to rotate, thereby realizing the intermittent rotation of the adsorption cylinder 321.

[0052] Based on the above, the invention will crush the larger bricks with tie bars, nails, etc. placed in the crushing and cutting device into powder, thereby completing the processing of the waste; the recovery device in the invention can attract the steel in the waste by magnetic force, separate it from the waste, and complete the recovery of the steel; the power parts set in the invention are linked to each other, so that the operation of the crushing and separation device can be realized while realizing the periodic rotation of the magnetic attraction part, which can not only take away the recovered steel, but also prevent idling and reduce waste.

[0053] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the above disclosed embodiments are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
