Description

Technical Field

[0001] The present invention relates to the technical field of construction waste treatment, and particularly to an intelligent treatment device for construction waste and waste materials. Background Art

[0002] With the acceleration of the urbanization process, the amount of construction waste generated increases year by year. Traditional treatment methods such as landfilling and simple crushing are not only inefficient but also prone to cause resource waste and environmental pollution. Construction waste often contains metal debris such as steel bars and iron wires. If not effectively separated, it will affect the quality of recycled aggregates and reduce their reuse value.

[0003] At present, construction waste treatment equipment mainly includes crushers, screening machines, and magnetic separators. The crusher crushes large pieces of construction waste, the screening machine classifies by particle size, and the magnetic separator separates metal debris through magnetism. However, the existing equipment has the following problems in the treatment of metal debris:

[0004] Low separation efficiency: Traditional magnetic separators have poor separation effects on fine or non-magnetic metal debris, resulting in metal residues.

[0005] Resource waste: Failure to effectively separate metal debris leads to a decline in the quality of recycled aggregates and low resource utilization rates. Summary of the Invention

[0006] In view of the deficiencies of the prior art, the present invention provides an intelligent treatment device for construction waste and waste materials, which solves the above-mentioned problems.

[0007] To achieve the above objectives, the present invention is realized through the following technical solutions: An intelligent treatment device for construction waste and waste materials includes a conveying frame and a powder material storage box arranged above the conveying frame. The inner cavity of the conveying frame is drivingly connected with a conveyor belt for conveying crushed stones driven by a magnetic driving wheel. The inner cavity of the conveying frame is fixedly connected with a magnetic adsorption plate located on the side of the conveyor belt for adsorbing metals inside the crushed stones. A guiding plate for guiding the crushed stones is arranged on the left side of the conveying frame. An outlet conveyor belt is arranged at the bottom of the guiding plate. A shielding cover adapted to the driving track of the conveyor belt inside the conveying frame is fixed on the right side of the guiding plate. A through groove communicating with the shielding cover is opened in the inner cavity of the guiding plate. A first blowing hopper communicated with a blower is fixed on one side of the shielding cover. The first blowing hopper faces the surface of the conveyor belt. By blowing air through the first blowing hopper to the conveyor belt inside the shielding cover, the crushed stones that have not fallen off its surface are blown down into the shielding cover, and then slide down along the through groove, pass through the guiding plate, and fall above the outlet conveyor belt for conveying, which can effectively perform secondary separation of metal debris and crushed stones;

[0008] One side of the discharge conveyor belt is communicated with a collection box. The top of the collection box is communicated with a guiding cylinder. The top of the guiding cylinder is fixedly connected with a recovery hopper located below the conveyor belt. An electromagnet rod that sequentially penetrates through the guiding cylinder and the recovery hopper is fixed inside the collection box. One side of the collection box is communicated with a second blowing hopper communicated with a blower. When in use, the metal scraps that lose the adsorption of the magnetic adsorption plate fall into the recovery hopper and settle downward. During the settling process, they are adsorbed by the electromagnet rod. At this time, because the second blowing hopper below continuously blows air, a negative pressure is formed in the guiding cylinder, and the internal dust quickly enters the lower collection box and is blown onto the discharge conveyor belt for output. The internal metal scraps are adsorbed by the electromagnet rod for three times of separation. Then, after adsorbing a certain amount, the second blowing hopper is closed, and the power supply of the electromagnet rod is disconnected. The metal scraps fall into the collection box for centralized treatment.

[0009] As a further scheme of the present invention: the through groove gradually rises from left to right, and the end of the magnetic adsorption plate is located on the right side of the shielding cover. The conveyor belt may still adsorb metal scraps at the shielding cover. At this time, it helps to separate the crushed stones and metal scraps. After moving past the shielding cover, the suction is lost at this time, and the metal scraps fall.

[0010] As a further scheme of the present invention: a plurality of cams driven by a motor are rotatably connected to the surface of the conveyor frame. The cams are in contact with the inner ring of the conveyor belt. The conveyor belt is vibrated by the cams, and the crushed stones above are vibrated, so that they are evenly in contact with the surface of the conveyor belt, and the metal scraps are effectively adsorbed.

[0011] As a further scheme of the present invention: a guide wheel in contact with the conveyor belt is rotatably connected to one side of the conveyor frame. The guide wheel is arranged on the right side of the recovery hopper. The conveyor belt is guided by the guide wheel to rise a part, changing the inclination angle, so that the metal scraps above fall onto the upper part of the recovery hopper.

[0012] As a further scheme of the present invention: the sides of the recovery hopper and the shielding cover are both fixedly connected to the side of the conveyor frame, playing a role of simple sealing and preventing dust from splashing.

[0013] As a further scheme of the present invention: two discharge channels are respectively communicated with the bottom of the powder storage box. The two discharge channels respectively face the bottom and the middle of the conveyor belt, and can discharge materials from two sides, increasing the discharge speed.

[0014] As a further scheme of the present invention: two partition plates driven by cylinders are respectively arranged at the bottom of the powder storage box. By the extension of the partition plates, the powder stones are blocked, and only the lower metal scraps can pass through. As the conveyor belt moves, the powder stones roll over repeatedly, so that the metal scraps located above can also be fully in contact with the conveyor belt and are effectively adsorbed.

[0015] The present invention has the following beneficial effects compared with the prior art:

[0016] 1. In the present invention, during the sedimentation process, the inner electromagnet rod adsorbs. At this time, because the second blowing hopper below continuously blows air, a negative pressure is formed in the guiding cylinder, and the dust inside quickly enters the lower collection box and is blown onto the discharge conveyor belt for output. The metal debris inside is adsorbed by the electromagnet rod for three - stage separation. Then, after adsorbing a certain amount, the second blowing hopper is closed, and the power supply of the electromagnet rod is disconnected, and the metal debris falls into the collection box for centralized treatment.

[0017] 2. In the present invention, the first blowing hopper blows air on the conveyor belt inside the shielding cover, blows the un - shed crushed stones on its surface down into the shielding cover, and then slides down along the through - slot and falls onto the discharge conveyor belt above through the guiding plate for conveying, which can effectively separate the metal debris and the crushed stones for the second time.

[0018] 3. In the present invention, through the extension of the partition plate, the powdered stones are blocked, and only the metal debris below can pass through. As the conveyor belt moves, the powdered stones roll repeatedly, so that the metal debris located above can also fully contact the conveyor belt for effective adsorption.

[0024] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following, in combination with the attached drawings and preferred embodiments, details the specific implementation manners, structures, features and their effects of the present invention as follows.

[0025] Please refer to Figures 1-4 , the present invention provides a technical solution: an intelligent treatment device for construction waste and waste, including a conveying frame 1 and a powder material storage box 2 arranged above the conveying frame 1. A transmission belt 4 for conveying crushed stones is driven by a magnetic driving wheel 3 in the inner cavity of the conveying frame 1. A magnetic attraction plate 5 for adsorbing metals inside the crushed stones is fixedly connected to the inner cavity of the conveying frame 1 on the side of the transmission belt 4. A guiding plate 8 for guiding the crushed stones is arranged on the left side of the conveying frame 1. An output conveyor belt 13 is arranged at the bottom of the guiding plate 8. A shielding cover 10 adapted to the transmission track of the transmission belt 4 inside the conveying frame 1 is fixed on the right side of the guiding plate 8. A through groove 9 communicating with the shielding cover 10 is opened in the inner cavity of the guiding plate 8. A first blowing hopper 11 communicated with a blower is fixed on one side of the shielding cover 10. The first blowing hopper 11 faces the surface of the transmission belt 4. By blowing the transmission belt 4 inside the shielding cover 10 through the first blowing hopper 11, the un-dropped crushed stones on its surface are blown down and fall into the shielding cover 10, and then slide down along the through groove 9, pass through the guiding plate 8 and fall above the output conveyor belt 13 for conveying, which can effectively separate the metal debris and the crushed stones for the second time;

[0026] One side of the output conveyor belt 13 is communicated with a collection box 12. A guiding cylinder 14 is communicated with the top of the collection box 12. A recovery hopper 16 located below the transmission belt 4 is fixedly connected to the top of the guiding cylinder 14. An electromagnet rod 15 sequentially passing through the guiding cylinder 14 and the recovery hopper 16 is fixed in the inner cavity of the collection box 12. A second blowing hopper 17 communicated with a blower is communicated with one side of the collection box 12. When in use, the metal debris that loses the adsorption of the magnetic attraction plate 5 falls into the recovery hopper 16 and sinks downward. During the sinking process, it is adsorbed by the electromagnet rod 15. At this time, because the second blowing hopper 17 blows continuously below, a negative pressure is formed in the guiding cylinder 14, and the dust inside quickly enters the collection box 12 below and is blown to the output conveyor belt 13 for output. The metal debris inside is adsorbed by the electromagnet rod 15 for the third separation. Then, after adsorbing a certain amount, the second blowing hopper 17 is closed and the power supply of the electromagnet rod 15 is disconnected, and the metal debris falls into the collection box 12 for centralized treatment.

[0027] The through groove 9 gradually rises from left to right. The end of the magnetic attraction plate 5 is located on the right side of the shielding cover 10. The transmission belt 4 may still adsorb the metal debris at the shielding cover 10. At this time, it helps to separate the crushed stones and the metal debris. After moving past the shielding cover 10, the suction is lost at this time and the metal debris falls.

[0028] A plurality of cams 6 driven by motors are rotatably connected to the surface of the conveying frame 1. The cams 6 are in contact with the inner ring of the transmission belt 4. The transmission belt 4 is driven to vibrate by the cams 6, and the crushed stones above are driven to vibrate, so that they are evenly in contact with the surface of the transmission belt 4, and the metal debris is effectively adsorbed.

[0029] One side of the conveying frame 1 is rotatably connected with a guide wheel 7 in contact with the conveyor belt 4. The guide wheel 7 is arranged on the right side of the recovery hopper 16. The conveyor belt 4 is guided by the guide wheel 7 to make it rise by a part, changing the inclination angle, so that the metal scraps above can fall onto the upper part of the recovery hopper 16.

[0030] The sides of the recovery hopper 16 and the shielding cover 10 are both fixedly connected to the side of the conveying frame 1, playing a role of simple sealing and preventing dust from splashing.

[0031] Two feeding channels 18 are respectively communicated with the bottom of the powder storage box 2. The two feeding channels 18 respectively face the bottom and the middle of the conveyor belt 4, and can feed materials from both sides, increasing the feeding speed.

[0032] Two partition plates 19 driven by cylinders are respectively arranged at the bottom of the powder storage box 2. By the extension of the partition plates 19, the powder stone materials are blocked, and only the metal scraps below can pass through. With the movement of the conveyor belt 4, the powder stone materials roll repeatedly, so that the metal scraps located above can also fully contact with the conveyor belt 4 and be effectively adsorbed.

[0033] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed as above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to the equivalent embodiments by using the disclosed technical content within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any brief modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
