Description

Technical Field

[0001] The utility model relates to the field of garbage separators, in particular to a garbage classification magnetic separation device. Background Art

[0002] In garbage separation, iron materials are an important separation category and have great recycling value. Therefore, it is necessary to separate the iron materials from them. Existing equipment such as the dry magnetic separator disclosed in the patent document with the publication number CN102580847B mainly works by setting a magnet inside one end of a conveyor belt to adsorb the iron materials in the garbage, preventing them from falling as the garbage moves, and then as the conveyor belt rotates to the lower part without a magnet, the iron materials fall to achieve the separation effect. However, this solution has some problems. Usually, the surface of the conveyor belt is flat and the resistance is relatively small. When the iron materials are about to move away from the magnet along with the conveyor belt, the adsorption force of the magnet is very likely to adsorb and hold the iron materials, causing the iron materials to slip on the surface of the conveyor belt and accumulate at the ferromagnetic part, that is, the iron materials cannot be smoothly separated from the belt. This even forms a resistance to the iron materials coming from behind, making it more difficult for the subsequent iron materials to be separated from the endless belt and unable to collect the iron materials smoothly. Content of the Utility Model

[0003] To solve the above technical problems, the utility model provides a garbage classification magnetic separation device, which can well adsorb the iron materials in the garbage and will not accumulate at one place on the endless belt, and can collect the iron materials more conveniently.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a garbage classification magnetic separation device, including a bracket, a runner and an endless belt;

[0005] The bracket includes a feeding end and a discharging end. An upper feeding device is arranged on the upper side of the feeding end, an iron material collection bin is arranged on the lower side of the feeding end, and a general collection bin is arranged on the lower side of the discharging end;

[0006] The feeding end and the discharging end are respectively rotationally matched with the runner, and the two runners are connected by winding with the endless belt. A first magnet is arranged corresponding to the inner side of the endless belt at the discharging end of the bracket;

[0007] A plurality of strip-shaped protrusions are arranged on the outer surface of the endless belt, and the strip-shaped protrusions are arranged perpendicular to the length direction of the endless belt.

[0008] The garbage mixed with iron materials is placed on the annular belt from the feeding end and transported to the discharging end through the annular belt, and then falls down into the ordinary collection bin. Since the bracket at the discharging end is provided with a first magnet, the iron materials in the garbage will be adsorbed. The iron materials continue to move downward along the annular belt. When the iron materials leave the discharging end, due to the lack of adsorption of the first magnet, the iron materials will fall downward. There is an iron material collection bin below, and the iron materials will be collected by the iron material collection bin. Since the annular belt is provided with strip-shaped protrusions, the iron materials adsorbed on the annular belt will be blocked by the strip-shaped protrusions, making it more difficult for them to be adsorbed by the magnet and slip on the annular belt. Instead, they move away from the first magnet along with the annular belt, preventing the iron materials from accumulating at the discharging end.

[0009] Preferably, the runner includes a driving runner and a driven runner. The driving runner is driven by a motor, and the driving runner and the driven runner are connected by winding the annular belt around them. This facilitates driving the annular belt to rotate.

[0010] Preferably, the strip-shaped protrusion is a strip-shaped partition. It can provide a higher separation, completely separating the iron materials in different areas and preventing them from slipping on the annular belt.

[0011] Preferably, the outer surface of the runner corresponding to the discharging end is distributed with the first magnet. So as to provide an uninterrupted adsorption force for the iron materials at the discharging end.

[0012] Preferably, a second magnet is provided below the annular belt corresponding to the feeding end. So as to adsorb the iron materials on the annular belt downward below, preventing the iron materials from not falling on the annular belt.

[0013] Preferably, the second magnet is a plurality of strip-shaped rod structures. It has a large coverage area and at the same time facilitates the downward fall of the iron materials.

[0014] Preferably, the second magnets are arranged side by side, and there is a discharging gap left between adjacent second magnets. It has a large coverage area and at the same time facilitates the downward fall of the iron materials.

[0015] Preferably, the second magnet includes an iron core and a coil. The iron core is a long strip iron rod, and the coil is wound around one end of the long strip iron rod. After the coil is combined with the iron core, an electromagnet is formed. The iron core will provide the magnet adsorption. After adsorbing the iron materials downward, the power supply of the coil can be turned off, and the adsorption force fails. The iron materials adsorbed on the iron core will fall downward.

[0016] Preferably, a protective film is detachably sleeved outside the iron core. It can prevent the iron materials from directly contacting the iron core, protect the iron core, and the iron materials adhered to the iron core can be removed together by removing the protective film.

[0017] Preferably, the protective film is a disposable strip plastic bag, which has a lower cost and is more convenient for installation and disassembly.

[0019] This solution can well adsorb the iron materials in the garbage and will not accumulate at one place of the endless belt, making it more convenient to collect the iron materials. Description of the drawings

A first magnet 4 is arranged corresponding to the inner side of the endless belt 11 at the discharging end of the bracket 3; a plurality of strip protrusions 5 are arranged on the outer surface of the endless belt 11, and the strip protrusions 5 are arranged perpendicular to the length direction of the endless belt 11.

[0027] The garbage mixed with iron materials is placed on the annular belt 11 from the feeding end and transported to the discharging end through the annular belt 11, and then falls downward into the ordinary collection bin 7. Since the support 3 at the discharging end is provided with a first magnet 4, the iron materials in the garbage will be adsorbed. The iron materials continue to move downward along the annular belt 11. When the iron materials leave the discharging end, due to the absence of the adsorption of the first magnet 4, the iron materials will fall downward. There is an iron material collection bin 8 below, and the iron materials will be collected by the iron material collection bin 8. Since the annular belt 11 is provided with strip-shaped protrusions 5, the iron materials adsorbed on the annular belt 11 will be blocked by the strip-shaped protrusions 5, making it more difficult to be adsorbed by the magnet and slip on the annular belt 11. Instead, they will move away from the first magnet 4 along with the annular belt 11, avoiding the accumulation of iron materials at the discharging end.

[0028] The runner includes a driving runner 1 and a driven runner 2. The driving runner 1 is driven by a motor, and the driving runner 1 and the driven runner 2 are connected by winding around the annular belt 11. It is convenient to drive the annular belt 11 to rotate.

[0029] The strip-shaped protrusion 5 is a strip-shaped partition. It can provide a higher partition, completely separating the iron materials in different areas and avoiding slipping on the annular belt 11.

[0030] The outer surface of the runner corresponding to the discharging end is distributed with the first magnet 4. So as to provide an uninterrupted adsorption force for the iron materials at the discharging end.

[0031] A second magnet 6 is provided below the annular belt 11 corresponding to the feeding end. So as to adsorb the iron materials on the annular belt 11 downward below and avoid the iron materials from not falling on the annular belt 11.

[0032] The second magnet 6 is of a structure of several strip-shaped rods. It has a large coverage area and at the same time is convenient for the iron materials to fall downward.

[0033] Combined Figure 2 As shown, the second magnets 6 are arranged side by side, and there is a discharging interval left between adjacent second magnets 6. It has a large coverage area and at the same time is convenient for the iron materials to fall downward.

[0034] The second magnet 6 includes an iron core 9 and a coil 10. The iron core 9 is a long strip iron rod, and the coil 10 is wound around one end of the long strip iron rod. After the coil 10 is combined with the iron core 9, an electromagnet is formed. The iron core 9 will provide magnetic adsorption. After adsorbing the iron materials downward, the power supply of the coil 10 can be turned off, and the adsorption force fails. The iron materials adsorbed on the iron core 9 will fall downward.

[0035] A protective film is detachably sleeved outside the iron core 9. This can prevent direct contact between the iron material and the iron core 9, protect the iron core 9, and remove the iron material adhered to the iron core 9 by removing the protective film. The protective film is a disposable strip plastic bag, which has a lower cost and is more convenient for installation and disassembly.

[0036] Advantages of the present utility model:

[0037] This solution can well adsorb the iron materials in the garbage and will not accumulate at one place on the annular belt 11, making it more convenient to collect the iron materials.
