Abstract
Description
Technical Field
[0001] This utility model relates to the field of waste treatment device technology, and in particular to a construction waste treatment device. Background Technology
[0002] Construction waste treatment equipment is a specialized device used to process waste generated during construction. This waste may include concrete, bricks, wood, metal, plastics, and more. The purpose of treating this waste is to reduce environmental impact, conserve resources, and comply with relevant environmental regulations.
[0003] A search revealed that Chinese Patent Publication No. CN219463527U discloses a construction waste treatment device, including a housing with a filter plate fixedly connected to the inner wall of the housing. A spraying mechanism is located on the right side of the housing, and a processing mechanism is located inside the housing. The spraying mechanism includes a fixing part and a connecting part, with the fixing part located on the right side of the housing and the connecting part located above the fixing part. The processing mechanism includes a crushing part and a cleaning part, with the crushing part located inside the housing and the cleaning part located below the crushing part. A water pump located on the fixing part is activated, drawing water from inside the housing through an inlet pipe and delivering it to the spray heads through an outlet pipe. The spray heads spray water onto the device, washing away the dust generated during waste treatment. The sprayed water is then filtered and pumped out again to spray water onto the device, reducing dust pollution and making it more environmentally friendly.
[0004] Currently, after building materials are crushed, they contain various recyclable metals with high iron content. These metals can then be recycled and reused. However, some crushed materials are mixed with waste wood and waste plastic. If manual screening with handheld magnets is used, the workload is large. Furthermore, after a general magnetic separator adsorbs metals, it is difficult to clean and recycle the iron-containing waste without stopping the machine, as it is not easy to scrape it off. Utility Model Content
[0005] The purpose of this utility model is to address the aforementioned shortcomings in the existing technology by proposing a construction waste treatment device.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] Design a construction waste treatment device, including a base plate, a number of wheels are fixedly installed on the lower end of the base plate, the lower ends of the wheels roll in contact with the base, and two side plates of different heights are fixed on the upper two sides of the base plate, and a discharge ramp is fixed on the upper end of the two side plates.
[0008] Several hydraulic cylinders are fixedly installed on the upper end of the base plate. The hydraulic cylinders are equipped with piston rods for extension and retraction. A lifting platform is fixed on the upper end of the piston rods. The upper surface of the lifting platform is inclined and parallel to the material discharge ramp. Several magnets are also fixed on the upper surface of the lifting platform. The upper ends of the magnets are attached to the bottom surface of the material discharge ramp.
[0009] Several motors are fixedly distributed on one side of the base. The surface of the motor is fixed to the surface of the base by screws. The motor has a drive shaft inside. An eccentric wheel is fixed to the end of the shaft. The eccentric wheel is always closely attached to one side of the base plate.
[0010] In detail, the material discharge ramp is made of high-strength aluminum alloy material, and the slope thickness of the material discharge ramp does not exceed five millimeters.
[0011] In detail, the base has several baffles fixed at the end away from the motor, and rod sleeves are provided through the surface of the baffles. The connection between the rod sleeves and the baffles is fixed by welding.
[0012] In detail, a round rod is installed through the inside of the sleeve. One end of the round rod is fixed to the side wall of the base, and an anti-detachment block is fixed to the end of the round rod away from the baffle.
[0013] In detail, a spring is wound around the surface of the round rod, and the two ends of the spring are fixedly assembled with the end face of the rod sleeve and the end face of the anti-detachment block, respectively.
[0014] In detail, a cover is fixedly installed at the upper end of the feeding ramp. The cover is inclined at the same angle as the feeding ramp. Two dust collection cylinders distributed in front and behind are fixed through the surface of the cover. The dust collection cylinders have a right-angle curved structure.
[0015] In detail, an air pump is fixed to the upper end of the cover, and the air inlet of the air pump is connected and fixed to the flange at the port of the dust collection cylinder.

[0017] The design scheme proposed in this utility model has the following beneficial effects in application:
[0018] 1. This solution achieves automatic magnetic separation and screening of waste materials through the combination of a feeding ramp and magnets. Iron-containing waste materials are attracted by the magnets as they slide down, while non-iron waste materials slide down directly, resulting in efficient classification. The magnets and feeding ramps are designed to be detachable (the lifting platform can be adjusted via a hydraulic cylinder), which facilitates the centralized collection of adsorbed iron-containing waste materials. The feeding ramps are made of thin aluminum alloy, which does not affect magnetic adsorption and reduces separation resistance, significantly improving screening efficiency and ease of operation. It is suitable for the rapid resource recovery of construction waste.
[0019] 2. As described in 1, the eccentric wheel driven by the motor strikes the bottom plate, causing the feeding ramp to vibrate, promoting the sliding and screening of waste materials. The spring and round rod structure ensures smooth vibration reset. At the same time, the cover, dust collection cylinder, and air pump form a dust removal system. During screening, dust is sucked into the dust collection bag, effectively suppressing dust pollution. The vibration and dust removal work together to improve screening efficiency and improve the working environment, meeting environmental protection requirements. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0027] Reference Figures 1-5 A construction waste treatment device includes a base plate 1. Several wheels 11 are fixedly installed at the lower end of the base plate 1. The wheels 11 can only move in parallel and mainly play an auxiliary sliding role when the base plate 1 and the feeding ramp 14 are vibrating and screening. The lower ends of the wheels 11 roll in contact with the base 12. Two side plates 13 of different heights are fixed on the upper sides of the base plate 1. The feeding ramp 14 is fixed at the upper end of the two side plates 13. The feeding ramp 14 can receive the crushed fragments and make them slide down the feeding ramp 14. Metals with high iron content will be attracted by the magnet 17 below and will be attracted to the slope surface of the feeding ramp 14. Metals that cannot be attracted will slide down directly.
[0028] Several hydraulic cylinders 15 are fixedly installed on the upper end of the base plate 1. The hydraulic cylinders 15 are equipped with piston rods for extension and retraction. A lifting platform 16 is fixed on the upper end of the piston rods. The upper surface of the lifting platform 16 is inclined and parallel to the discharge ramp 14. Several magnets 17 are also fixedly distributed on the upper surface of the lifting platform 16. The upper ends of the magnets 17 are attached to the bottom surface of the discharge ramp 14. The magnets 17 are permanent magnets and can adsorb waste materials with high iron content through the discharge ramp 14 to achieve magnetic separation and screening.
[0029] Several motors 18 are fixedly distributed on one side of the base 12. The surface of the motors 18 is fixed to the surface of the base 12 by screws. The motors 18 have a drive shaft inside, and an eccentric wheel 19 is fixed to the end of the shaft. The eccentric wheel 19 is always in close contact with one side of the base plate 1. The motors 18 can drive the eccentric wheel 19 to rotate. Thus, by constantly contacting the base plate 1 at its near and far positions, compression or release can be achieved.
[0030] It should be further noted that the feeding ramp 14 is made of high-strength aluminum alloy, and the slope thickness of the feeding ramp 14 is no more than five millimeters. The thin structure will not affect the adsorption effect of the magnet 17. At the same time, it will not be greatly obstructed when the magnet 17 separates from the feeding ramp 14. During magnetic separation and screening, the magnet 17 comes into contact with the feeding ramp 14, which can screen waste materials with low iron content. When collecting the iron-containing waste after screening, it can be separated from the feeding ramp 14 by the magnet 17, so that the iron-containing waste can be fed in a centralized manner for unified collection.
[0031] It should be further noted that a number of baffles 2 are fixed at the end of the base 12 away from the motor 18. A rod sleeve 21 is provided through the surface of the baffle 2. The connection between the rod sleeve 21 and the baffle 2 is fixed by welding. There are at least three baffles 2, which are equidistant from each other.
[0032] It should be further explained that a round rod 22 is provided through the inside of the rod sleeve 21. One end of the round rod 22 is fixed to the side wall of the base 12, and an anti-detachment block 23 is fixed to the end of the round rod 22 away from the baffle 2. By sliding and extending the round rod 22 in multiple positions with the corresponding rod sleeve 21, it can have a horizontal stability limiting effect when the base plate 1 moves back and forth.
[0033] It should be further explained that a spring 24 is wound around the surface of the round rod 22. The two ends of the spring 24 are fixedly assembled with the end face of the rod sleeve 21 and the end face of the anti-detachment block 23, respectively. The spring 24 can play a reset effect when the base plate 1 reciprocates, thereby ensuring the stability of the reciprocating vibration of the entire feeding ramp 14.
[0034] It should be further explained that a cover 3 is fixedly installed at the upper end of the discharge ramp 14. The cover 3 has the same inclination angle as the discharge ramp 14. Two dust collection cylinders 31 are fixedly installed on the surface of the cover 3, which are distributed in front and behind. The dust collection cylinders 31 have a right-angle curved structure. When waste material is poured into the discharge ramp 14, the dust can be sucked into the dust collection cylinders 31 by the air pump 32 to prevent it from overflowing.
[0035] It should be further noted that an air pump 32 is fixed at the upper end of the cover 3. The air inlet of the air pump 32 is connected and fixed to the flange at the port of the dust collection cylinder 31. The air pump 32 can provide sufficient suction effect to ensure the suction strength during the dust collection process.
[0036] It should be further noted that a dust collection bag 33 is fixedly installed in the horizontal position inside the dust collection cylinder 31. The dust collection bag 33 is made of non-woven fabric and can collect dust to prevent large-scale dust from being generated during the screening process of waste materials.
[0037] Working principle: This solution uses magnetic separation technology to separate metallic and non-metallic waste. The crushed waste enters from the high end of the feeding ramp 14. Due to the ramp's inclination, the waste slides down naturally under gravity. Magnets 17 are installed below the feeding ramp 14. When ferrous metal waste passes by, it is attracted to the ramp surface, while non-metallic waste continues to slide down, achieving initial separation. Simultaneously, the motor 18 drives the eccentric wheel 19 to rotate, periodically squeezing the bottom plate 1, causing it to vibrate horizontally. This vibration is transmitted to the feeding ramp 14, promoting more even dispersion of the waste and preventing accumulation. It also enhances the magnetic separation effect. The vibration also helps non-metallic waste slide down faster, while metallic waste remains temporarily on the ramp due to magnetic attraction until subsequent cleaning.
[0038] In this design, the vibration mechanism utilizes a motor 18, an eccentric wheel 19, and a spring 24 working in concert to ensure the stability of the vibrating screen. The motor 18 drives the eccentric wheel 19 to rotate, and its eccentric structure continuously presses against the base plate 1, causing it to reciprocate horizontally. The base plate 1 slides on the base 12 via wheels 11. The cooperation between the round rod 22 and the rod sleeve 21 restricts the direction of movement of the base plate 1, preventing deviation. The spring 24 is compressed or stretched as the base plate 1 moves, providing a restoring force and ensuring a stable vibration rhythm. This design allows the discharge ramp 14 to vibrate continuously and efficiently, promoting waste material flow while preventing structural damage due to excessive vibration. Furthermore, the baffle 2 and anti-detachment block 23 further reinforce the overall structure, ensuring stable operation of the device even under long-term vibration.
[0039] Dust is easily generated during waste treatment. The device effectively controls dust diffusion through the cover 3 and dust collection structure. The cover 3 covers the discharge ramp 14, and its tilt angle is consistent with the ramp to ensure that the flow of waste is not obstructed. The dust collection cylinder 31 generates negative pressure through the air pump 32 to suck the dust raised during screening into the dust collection bag 33. The non-woven dust collection bag 33 can efficiently filter dust and prevent it from being discharged into the environment. The continuous air pump 32 ensures stable dust collection effect, while the right-angle curved dust collection cylinder 31 design optimizes the airflow path and reduces dust escape.
[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
