Description

Technical Field

[0001] This utility model relates to the field of straw processing technology, and in particular to a metal removal device for the preparation of straw biofuel. Background Technology

[0002] With increasing environmental awareness and growing demand for renewable energy, straw biofuel, as a clean energy source, has received widespread attention. During the collection, transportation, and storage of straw, metal impurities such as nails and wires inevitably get mixed in. If these impurities enter subsequent processing stages such as crushing and molding, they will not only damage key equipment such as crushing blades and molding molds, leading to increased maintenance costs and shortened lifespan, but may also cause safety accidents. Existing metal removal devices suffer from low efficiency and incomplete removal when processing straw materials. Some devices can only remove metal impurities from the surface of the material, failing to effectively remove metal impurities inside the straw pile, which is detrimental to subsequent straw processing. Therefore, we propose a metal removal device for straw biofuel preparation. Utility Model Content

[0003] To address the aforementioned problems, this invention provides a metal removal device for straw biofuel preparation. This invention solves the problems of low removal efficiency and incomplete removal in existing metal removal devices when processing straw materials. Some devices can only remove metal impurities on the surface of the material, failing to effectively remove metal impurities inside the straw pile, which is detrimental to subsequent straw processing.

[0004] This utility model discloses a metal removal device for preparing straw biofuel, comprising a support frame, side plates on both sides of the upper end of the support frame, an active roller shaft on one side of each side plate, and a driven roller shaft on the side of each side plate away from the active roller shaft. First transmission wheels are located at both ends of the active and driven roller shafts. Two transmission wheels on the same side of the support frame are connected by a transmission belt. Multiple equally spaced support rods are located between the two transmission belts. A housing is located at the center of the upper part of the two side plates. A hydraulic cylinder is located in the center of the upper part of the housing. The stroke end of the hydraulic cylinder passes through the housing and is fixedly connected to a mounting plate. Multiple equally spaced electromagnets are located below the mounting plate.

Two transmission wheels 20 located on the same side of the support frame 1 are connected by a transmission belt 5. Multiple equally spaced support rods 6 are provided between the two transmission belts 5. When the active roller shaft 3 rotates, it drives the transmission wheels 20 to rotate. The drive wheel 20 on the side of the support frame 1 away from the drive roller 3 drives the driven roller 4 to rotate. Through the cooperation between the drive roller 3 and the driven roller 4, the transmission belt 5 can drive the support rod 6 to transport the straw. A housing 7 is provided in the middle of the upper part of the two side plates 2. A hydraulic cylinder 8 is provided in the middle of the upper part of the housing 7. The stroke end of the hydraulic cylinder 8 passes through the housing 7 and is fixedly connected to the mounting plate 9. Multiple electromagnets 10 are arranged at equal intervals below the mounting plate 9. When the hydraulic cylinder 8 is working, the hydraulic cylinder 8 pushes the mounting plate 9 to move back and forth in the vertical direction. Through the transmission of the mounting plate 9, the height of the electromagnets 10 also changes accordingly. When the electromagnets 10 are working, they can adsorb iron metal impurities in the straw.

[0016] The two side plates 2 are provided with two symmetrical support roller shafts 11 below the transmission belt 5. Both ends of the support roller shaft 11 are provided with guide wheels 21 that match the transmission belt 5. The support roller shaft 11 is higher than the driving roller shaft 3 and the driven roller shaft 4. The setting of the support roller shaft 11 allows the straw to change angle during the movement, which makes it easier for the electromagnet 10 to attract ferrous metal.

[0017] The support frame 1 is provided with a mounting frame 13 near the active roller shaft 3. A motor 14 is fixedly mounted on the mounting frame 13. The rotation shaft of the motor 14 passes through the mounting frame 13 and is fixedly connected to the first pulley 15.

When the motor 14 is working, the motor 14 drives the first pulley 15 to rotate. Through the transmission of the belt 17, the second pulley 16 can drive the active roller shaft 3 to rotate.

[0018] Guide rods 12 are inserted into both sides of the housing 7 located on the hydraulic cylinder 8. The lower part of the guide rods 12 is fixedly connected to the mounting plate 9. The guide rods 12 are movably connected to the housing 7. Through the mutual cooperation between the guide rods 12 and the housing 7, the movement stability of the mounting plate 9 is effectively improved.

[0019] Cabinet doors 18 are provided at both ends of the side walls of the housing 7. A groove 19 is provided on one side of each cabinet door 18. The cabinet door 18 makes it easier for staff to clean the electromagnet 10, and the groove 19 makes it easier to open and close the cabinet door 18.

[0020] Specifically, in this invention, when removing metal from straw, the straw is laid flat on the support rod 6. When the motor 14 is working, the motor 14 drives the first pulley 15 to rotate. Through the transmission of the belt 17, the second pulley 16 can drive the drive roller 3 to rotate. When the drive roller 3 rotates, it drives the transmission wheel 20 to rotate. The transmission wheel 20 drives the driven roller 4 to rotate through the transmission wheel 20 on the side of the support frame away from the drive roller 3. Through the mutual cooperation between the drive roller 3 and the driven roller 4, the... The transmission belt 5 can drive the support rod 6 to transport the straw. When the hydraulic cylinder 8 is working, the hydraulic cylinder 8 pushes the mounting plate 9 to move back and forth in the vertical direction. Through the transmission of the mounting plate 9, the height of the electromagnet 10 also changes accordingly. When the electromagnet 10 is working, it can adsorb ferrous metal impurities in the straw. The support roller shaft 11 is higher than the active roller shaft 3 and the driven roller shaft 4. The setting of the support roller shaft 11 allows the straw to change angle during the movement, which makes it easier for the electromagnet 10 to adsorb ferrous metals.
