Description

Technical Field

[0001] This utility model relates to the field of bulky waste sorting, and in particular to a high-efficiency iron removal conveyor for the initial crushing of bulky waste. Background Technology

[0002] With increasingly stringent environmental protection requirements and a continued severe resource crisis, bulky solid waste (especially construction waste, decoration waste, or scrapped vehicles) contains a large amount of recyclable resources, making its sorting, recycling, and reuse increasingly important. Bulk solid waste is typically crushed by a crusher into small pieces of waste, metal parts, dust, and film, which are then conveyed to secondary sorting equipment for heavy material separation (metal parts are mixed in with the heavy materials). The subsequent manual sorting of these materials has several drawbacks: firstly, manual sorting is slow, prone to omissions, has a low recycling rate, and presents a poor working environment and safety hazards; secondly, the sharp metal parts can easily damage the secondary sorting equipment and subsequent conveying equipment. Utility Model Content

[0003] To address one or more of the aforementioned problems, this utility model provides a high-efficiency iron removal conveyor for the initial crushing of large-sized waste.

[0004] According to one aspect of the present invention, the high-efficiency iron removal conveyor for primary crushing of large-sized waste includes: a gantry, a conveying body, an iron removal section, a discharge chute, an iron transfer device, and an upper connecting component;

[0005] The gantry is a three-dimensional rectangular frame formed by two longitudinal side frames symmetrically connected to two transverse upper beams, with four lower connecting seats symmetrically installed under the two upper beams.

[0006] The conveyor body is longitudinally inclined and passes through the lower end of the longitudinal door opening of the gantry;

[0007] The iron removal section includes a transverse belt conveyor and a magnetic platform. The middle section of the aluminum transverse frame of the transverse belt conveyor passes through the transverse door holes of the two side frame frames. The longitudinal ends of the transverse frame are connected to four lower connecting seats through upper connecting parts. The iron removal belt, which moves horizontally, is wrapped around the transverse frame. The iron removal belt is located above the material belt of the conveyor body. The magnetic platform is connected to the lower part of the transverse frame and is flush with and attached to the upper surface of the lower section of the iron removal belt. The magnetic platform is equipped with a magnet that attracts metal iron parts. The length of the magnet is greater than the width of the material belt.

[0008] The material feeding chute is horizontally inclined and located below the horizontal door hole of the side plate frame. Its inner end extends upward and into the lower part of the magnet and is located outside the material conveyor belt.

[0009] The feed inlet of the iron material transfer device is located directly below the discharge chute;

[0010] The material conveyor belt carries the longitudinally moving initial crushed material flow. The magnet attracts the metal iron parts to stick to the lower section of the iron removal belt and moves with the iron removal belt. When the magnet reaches the end of the magnet, the magnetism is eliminated, and the metal iron parts fall into the discharge chute and enter the iron material transfer device.

[0011] In some embodiments, the transverse belt conveyor also includes a drive roller, a driven roller, and multiple longitudinal support rollers. Both ends of the drive roller and the driven roller are connected to the lower part of the transverse frame via lower belt bearings, and the longitudinal support rollers are connected to the upper part of the transverse frame via upper belt bearings. The drive roller, the driven roller, and the longitudinal support rollers are wrapped by an iron removal belt, and the drive roller is connected to an iron removal motor via a transmission assembly.

[0012] In some embodiments, the iron removal motor is threadedly connected to the motor plate at one end of the transverse frame, and the first tensioning assembly is fixedly connected to the motor plate and presses against the inner end foot of the iron removal motor.

[0013] The two second tensioning components press outwards to tighten the bearings on the two discs.

[0014] In some embodiments, the first tensioning assembly includes a first adjusting plate and two sets of laterally adjustable threaded adjusting parts. The first adjusting plate is vertically welded to the inner end of the motor plate. The adjusting bolts of the two threaded adjusting parts are threadedly connected to the threaded holes of the first adjusting plate, and their ends abut against the inner end foot of the iron removal motor. The locking nuts of the threaded adjusting parts are sleeved on the adjusting bolts and fit against the outer wall of the first adjusting plate.

[0015] In some embodiments, the transverse frame is symmetrically provided with lifting lugs at both ends in the longitudinal direction. The upper connecting parts are four steel wire ropes or four lifting rods. The upper ends of the four upper connecting parts are connected to the lower connecting seats and the lower ends are fixedly connected to the lifting lugs, so that the iron removal part is tilted and suspended above the conveying body.

[0016] Alternatively, the upper connecting part consists of two longitudinally arranged upper frame frames, with the upper end of the upper frame fixedly connected to the lower connecting seat on one side and the lower end fixedly connected to one end of the transverse frame, thereby making the iron removal part tilted and fixed above the conveying body.

[0017] In some implementations, the iron removal motor is a helical gear reducer motor, the magnetic field strength of the magnet is 900 Gs, and the height of the magnet relative to the initial crushed material flow is 250 mm.

[0018] In some implementations, the iron transfer device is a moving box with rollers or a belt conveyor.

[0019] In some implementations, the feeding chute is made of stainless steel and its two ends are adjustable to the upright legs on both sides of the side frame.

[0020] In some embodiments, the conveying body includes a conveyor frame, side cover plates fixedly connected to both longitudinal sides of the conveyor frame, and a material belt wrapped inside the conveyor frame;

[0021] The rollers at both ends of the conveyor frame are in close contact with the ends of the material belt. Several upper support rollers are installed at equal intervals on the upper end of the conveyor frame, and several lower support rollers are supported at equal intervals below. The material belt is supported by the upper and lower support rollers.

[0022] In some implementations, the length of the conveying body is slightly greater than that of the gantry, with the high end being the feed end and the low end being the discharge end. A horizontal high-level conveyor is provided above the front end of the high-level conveyor and a horizontal low-level conveyor is provided below the rear end of the low-level conveyor. The moving speed of the high-level conveyor is less than that of the conveying body. The initial crushed material flow enters the conveying body and is dispersed due to tilting, tumbling, and speed difference.

[0023] This high-efficiency iron removal conveyor for primary crushing of bulky waste is integrated and installed at the discharge end of the bulky waste crusher, realizing automated online sorting of ferrous metals. Its advantages are: First, automated sorting is fast and efficient, with minimal omissions and a high recovery rate, avoiding safety hazards to sorting personnel caused by harsh working environments, ensuring high safety; Second, metals are sorted out first at the discharge end, preventing them from entering secondary sorting equipment, effectively protecting the secondary sorting equipment and subsequent conveying equipment; Third, the structure is simple, allowing for direct modification to the existing crusher's discharge conveyor belt, resulting in low modification costs, no increase in operating area, no additional operators, and low sorting costs.

Its beneficial effects are: the three-dimensional frame has high strength, high resistance to impact loads, and stable overall structure, which helps to remove iron stably and efficiently.

[0039] The conveying body 2 is longitudinally inclined and passes through the lower end of the longitudinal door hole 13 of the gantry 1;

[0040] The iron removal section 3 includes a transverse belt conveyor 30 and a magnetic platform 31. The middle section of the aluminum transverse frame 300 of the transverse belt conveyor 30 passes through the transverse door holes 100 of the two side frame frames 10. The longitudinal ends of the transverse frame 300 are connected to four lower connecting seats 11 through upper connecting parts 6. The iron removal belt 38, which moves horizontally, is wrapped around the transverse frame 300. The iron removal belt 30 is located above the material belt 20 of the conveying body 2. The magnetic platform 31 is connected to the lower part of the transverse frame 300 and is flush with and attached to the upper surface of the lower section of the iron removal belt 38.
