Description

Technical Field

[0001] This utility model relates to the field of bagasse screening technology, and in particular to a combined screening machine for efficient sand and iron removal from bagasse. Background Technology

[0002] Bagasse is the fibrous residue left after sugarcane is pressed to extract sugar. With the development of comprehensive resource utilization technology, bagasse has become a valuable renewable biomass resource and is widely used in many industrial fields such as papermaking, artificial board manufacturing, biomass pellet fuel, animal feed and cultivation substrate, realizing the transformation of waste into treasure.

[0003] During the collection, transportation, and stacking of bagasse, it is very easy for it to be mixed with mineral impurities such as sand and stones, as well as metal impurities such as iron wire and nails. In order not to affect the subsequent processing of recycled resources, screening equipment is usually used to screen out impurities such as sand and metal impurities inside the bagasse that may affect subsequent processing. This is an indispensable key pretreatment step to ensure production safety, protect equipment, and improve the quality of the final product.

[0004] Currently, most bagasse processing production lines use a separation method of screening first and then removing iron. This involves first feeding the bagasse into a vibrating screen or drum screen to separate sand and gravel, and then feeding the material into a separate magnetic separator for iron removal. This step-by-step operation not only increases the number of material transfers and occupies more space, but also makes the entire screening process more cumbersome, and the screening efficiency needs improvement. Therefore, a combined screening machine for high-efficiency sand and iron removal from bagasse is proposed to solve these problems. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 - Figure 3This utility model provides an embodiment of a combined screening machine for high-efficiency sand and iron removal from bagasse, comprising a casing 1, a rotating rod 2 rotatably connected to the inner wall of the casing 1, and a screen hopper 3 slidably connected to the outer wall of the rotating rod 2. A guide groove is provided on the outer wall of the rotating rod 2 to guide the screen hopper 3, allowing the screen hopper 3 to slide axially along the outer wall of the rotating rod 2. Rotation of the rotating rod 2 causes the screen hopper 3, slidably connected to its outer wall, to gradually rotate upwards. Rotation of the screen hopper 3 allows all the bagasse that has been screened to be poured downwards, thus enabling rapid discharge of the screened bagasse. The top of the screen hopper 3 is open, and the bottom of the screen hopper 3 is arc-shaped with a screen mesh inside. Used for screening sand and gravel in bagasse, the inner wall of the right side of the screen bucket 3 is rotatably connected to a rotating shaft 4, and the left end of the rotating shaft 4 is fixedly connected to a connecting plate 5. The inner wall of the connecting plate 5 is threaded with a magnetic component 6. The threaded connection makes it easy to disassemble the magnetic component 6 so as to clean the metal impurities attached to its outer wall. The magnetic component 6 is a "cylindrical" magnet. When the connecting plate 5 swings back and forth inside the screen bucket 3, it will drive the magnetic component 6 to move back and forth inside the bagasse. At this time, the magnetic force of the magnetic component 6 itself can be used to attract metal impurities inside the bagasse, such as iron nails, iron wires, iron filings, etc. The rotating rod 2 and the outer wall of the screen bucket 3 are provided with a driving mechanism 7, and the right side of the casing 1 is provided with a flipping component 8.

[0033] Reference Figure 2 - Figure 4 The drive mechanism 7 includes a servo motor 71, which is fixedly connected to the outer wall of the rotating rod 2. The output end of the servo motor 71 is fixedly connected to a drive shaft 72, which passes through and is rotatably connected to the inner wall of the rotating rod 2. When the servo motor 71 is started, it drives the drive shaft 72 to rotate. At this time, the drive shaft 72 will rotate on the inner wall of the rotating rod 2. The bottom end of the drive shaft 72 is fixedly connected to a turntable 73. When the drive shaft 72 rotates, it will drive the turntable 73 to rotate synchronously. A slider 75 is slidably connected to the outer right side of the screen bucket 3. A swing rod 77 is fixedly connected to the right end of the rotating shaft 4. When the swing rod 77 swings up and down, it will drive the rotating shaft 4 to rotate back and forth on the inner right side of the screen bucket 3. When the rotating shaft 4 rotates back and forth, it will drive the connecting plate 5 to swing back and forth inside the screen bucket 3.

[0034] Reference Figure 2 A connecting rod 74 is hinged to the bottom of the turntable 73. The hinge point between the connecting rod 74 and the turntable 73 is off-center from the axis of the turntable 73. The end of the connecting rod 74 away from the turntable 73 is hinged to the right side wall of the screen hopper 3. When the turntable 73 rotates, it will drive one end of the connecting rod 74 to make a circular motion around the drive shaft 72. At this time, the other end of the connecting rod 74 will push and pull the screen hopper 3 back and forth, so that the screen hopper 3 slides axially back and forth on the outer wall of the rotating rod 2.

[0035] Reference Figure 2A connecting rod 76 is hinged to the right end of the slider 75. The end of the connecting rod 76 away from the slider 75 is hinged to the outer wall of the rotating rod 2. While the slider 75 moves back and forth, it will be pushed and pulled back and forth by the connecting rod 76, causing the slider 75 to slide back and forth up and down on the right side wall of the screen hopper 3.

[0036] Reference Figure 2 The bottom end of the slider 75 is hinged to a hinge rod 78. The end of the hinge rod 78 away from the slider 75 is hinged to the side wall of the swing rod 77. While the slider 75 slides up and down, it pushes and pulls the hinge rod 78 back and forth, causing the hinge rod 78 to push and pull the swing rod 77 back and forth. At this time, the swing rod 77 will swing up and down around the central axis of the rotating shaft 4.

[0037] Reference Figure 2 The flipping assembly 8 includes a stepper motor 81, which is fixedly connected to the outer right side of the housing 1. When the worm gear 83 rotates, it drives the rotating rod 2 to rotate synchronously on the inner wall of the housing 1. When the rotating rod 2 rotates, it can drive the screen bucket 3, which is slidably connected to its outer wall, to flip inside the housing 1 so as to pour out the bagasse after screening. The output end of the stepper motor 81 is fixedly connected to a worm 82, and the right end of the rotating rod 2 is fixedly connected to a worm gear 83. The worm gear 83 meshes with the worm 82. When the stepper motor 81 is started, it drives the worm 82 to rotate. When the worm 82 rotates, it drives the worm gear 83 that meshes with it to rotate.

[0038] Working principle: The bagasse that needs to be desanded and iron removed is poured into the inside of the screen hopper 3, and the servo motor 71 is started to drive the drive shaft 72 to rotate. When the drive shaft 72 rotates, it will drive the turntable 73 to rotate synchronously. When the turntable 73 rotates, it will drive one end of the connecting rod 74 to make a circular motion around the drive shaft 72. At this time, the other end of the connecting rod 74 will push and pull the screen hopper 3 back and forth, so that the screen hopper 3 slides axially back and forth on the outer wall of the rotating rod 2. Through the back and forth sliding of the screen hopper 3, the bagasse inside can be shaken back and forth. Through the back and forth shaking of the bagasse, the sand and gravel attached to its surface can be shaken off, so that the sand and gravel can be separated from the bagasse and fall down through the screen hopper 3. In this way, the bagasse and sand and gravel can be screened.

[0039] While the sieve bucket 3 reciprocates and screens sand and gravel, it drives the slider 75 to move synchronously back and forth. Simultaneously, the slider 75 is pushed and pulled by the connecting rod 76, causing it to slide up and down the right side wall of the sieve bucket 3. This up-and-down sliding motion also pushes and pulls the hinge rod 78, causing the hinge rod 78 to push and pull the swing rod 77. The swing rod 77 then swings up and down around the central axis of the rotating shaft 4, simultaneously driving the rotating shaft 4 to rotate back and forth on the right inner wall of the sieve bucket 3. This rotation of the rotating shaft 4 also causes the connecting plate 5 to swing back and forth inside the sieve bucket 3. The connecting plate 5 then drives the magnetic component 6 to move back and forth inside the bagasse. This back-and-forth movement of the magnetic component 6 allows it to fully contact the bagasse, enabling it to use its own magnetic force to adsorb metallic impurities such as iron nails, iron wires, and iron filings. This process effectively screens the metallic impurities inside the bagasse.

[0040] After the bagasse is screened to remove sand and iron, the stepper motor 81 can be started to drive the worm gear 82 to rotate. As the worm gear 82 rotates, it drives the worm wheel 83 meshing with it to rotate. As the worm wheel 83 rotates, it drives the rotating rod 2 to rotate synchronously on the inner wall of the machine casing 1. As the rotating rod 2 rotates, it drives the screen bucket 3, which is slidably connected to its outer wall, to gradually flip upward. By flipping the screen bucket 3, all the bagasse that has been screened inside can be poured downward. At the same time, the bagasse unloaded from the screen bucket 3 is collected using a container, thus improving the bagasse feeding efficiency.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
