Abstract
Description
Technical Field
[0001] This utility model belongs to the field of sunflower seed processing equipment, specifically relating to a sunflower seed specific gravity selection and dust removal system. Background Technology
[0002] Sunflower seed raw materials often contain a large amount of impurities such as stones, dust, and straw. Before processing, these materials need to undergo impurity removal and dust removal operations. Gravity separators rely on power to cause the screen body to vibrate reciprocatingly, creating relative movement between the material and the working surface. This airflow helps separate materials with different densities. The vibrations during material separation generate dust, necessitating a dust removal function. After a period of operation, the dust collector filter plates need to be cleaned regularly to ensure the efficiency of the dust removal system. Currently, most gravity separators use fixed or pull-out dust collector plates, making replacement during regular maintenance inconvenient. Utility Model Content
[0003] In order to overcome the shortcomings of the existing technology, this utility model aims to provide a specific gravity dust removal system for sunflower seeds. This application can effectively filter the smoke and dust generated during the operation of the specific gravity machine, with better dust removal effect. At the same time, the cleaning and maintenance of the dust removal filter plate is very convenient, which can significantly improve the maintenance efficiency of the specific gravity machine.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] A specific gravity separation dust removal system for sunflower seeds includes a dust removal hood installed above the casing of a specific gravity separator. Multiple dust removal components are arranged around the hood, each including a suction fan, a filter plate, and an L-shaped duct. The suction fan is mounted on the side wall of the casing. The horizontal section of the duct connects to the side of the dust removal hood, and the vertical section connects downwards to the air inlet of the suction fan. The filter plate is installed in the middle of a frame, which is horizontally movable within the vertical section of the duct and lower than its horizontal section. An inspection port is provided on the top surface of the horizontal section of the duct, opposite the position of the filter plate, and a sealing plate is provided at the inspection port. A lifting mechanism is also installed on the duct and connected to the frame.
[0006] Preferably, the sealing plate includes two open cover plates, and the lifting mechanism includes two sets of horizontally symmetrically arranged linkage swing assemblies, each set of linkage swing assemblies being connected to the corresponding upper cover plate; the linkage swing assembly includes a first link, a second link, a third link, a fourth link, and a sector gear, the first link and the second link are arranged parallel to each other and located outside the duct, the upper ends of the first link and the second link are rotatably connected to the same straight line on the side of the cover plate, the lower end of the second link is rotatably connected to the outer wall of the duct, and the lower end of the first link is vertically fixed. The rotating shaft is rotatably connected to the duct wall; the center of the sector-shaped gear ring outside the duct is also fixed to the rotating shaft; the rotating shaft moves through the duct and extends into its interior; the third and fourth connecting rods are located inside the duct; the lower end of the third connecting rod is vertically fixed to the rotating shaft, the upper end of the third connecting rod is inclined to one side and rotatably connected to the lower end of the fourth connecting rod, and the upper end of the fourth connecting rod is inclined to the other side and rotatably connected to the frame; the fourth connecting rods of the two connecting rod swing assemblies are connected on the same straight line of the frame; the sector gears of the two connecting rod swing assemblies mesh with each other.
[0007] Preferably, a limiting groove is vertically formed on the inner wall of the duct, and a limiting slider is provided on the side of the frame protruding outward, the limiting slider being slidably formed in the limiting groove.
[0008] Preferably, the tops of the two cover plates are fastened together by snap-locking.
[0009] Preferably, the two cover plates are provided with sealing components on opposite sides. The sealing components include a sealing strip protruding from one side of the cover plate and a receiving groove opened on the opposite side of the other cover plate. The sealing strip and the receiving groove are engaged.
[0010] Preferably, the opening of the inspection port is provided with a sealing ring that mates with the sealing plate.
[0011] Preferably, a handle is also installed on the top of the cover plate.
[0012] The beneficial effects of this utility model are as follows:
[0013] 1. When the gravity separator is in operation, the dust can be drawn outward through the air ducts set around the dust removal hood under the action of the suction fan. The dust flows along the L-shaped air ducts and can effectively filter dust and debris when passing through the dust filter plate, thus achieving a highly efficient air purification effect.
[0014] 2. When cleaning, maintaining, or replacing the dust filter plate, the two covers are pulled horizontally to both sides using the handle at the top, causing the two sets of first and second connecting rods to rotate and swing. This causes the shaft connected to the first connecting rod to rotate, and the meshing of two sector gears ensures that the two sets of connecting rod swinging components move in unison. The third connecting rod, which is fixed to the shaft, swings to both sides, pushing the fourth connecting rod upward and rotating. This causes the fourth connecting rod to lift the dust filter plate mounted on the frame vertically upward and move it to the maintenance port. This eliminates the need for personnel to disassemble the equipment or insert their bodies into the duct, thus significantly improving the maintenance efficiency of the dust filter plate.
[0015] 3. This utility model can significantly improve the stability of the frame when it moves up and down by using the combination of the limiting groove and the limiting slider.
[0016] 4. The tops of the two cover plates of this utility model are fastened together by snap-locking. When the two cover plates are closed, they are fixed by snap-locking, which can significantly improve the convenience of opening and closing the sealing plate.
[0017] 5. After the two cover plates of this utility model are fitted together at the inspection port, the sealing performance at the joint of the sealing plates can be significantly improved through the cooperation of the sealing strip and the receiving groove, preventing smoke and dust from spreading outward. In addition, a sealing ring that cooperates with the sealing plate is provided at the opening of the inspection port, thereby improving the connection and sealing performance between the inspection port and the sealing plate.

[0024] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of application of this utility model.
[0025] like Figure 1-6As shown, this utility model proposes a dust removal system for specific gravity separation of sunflower seeds, including a dust removal hood 11, which is installed above the casing 1 of the specific gravity separator. Multiple dust removal components are arranged around the dust removal hood 11, including a suction fan 3, a filter plate 7, and an L-shaped duct 2. The suction fan 3 is installed on the side wall of the casing 1. The horizontal part of the duct 2 connects to the side of the dust removal hood 11, and the vertical part of the duct 2 connects downwards to the air inlet of the suction fan 3. The filter plate 7 is installed in the middle of a frame 6, which is horizontally movable within the vertical part of the duct 2 and lower than the height of its horizontal part. The duct 2 has a square cross-section, and the frame 6 also adopts a square structure adapted to it.
[0026] When the gravity separator is in operation, the smoke and dust can be drawn outward through the air ducts 2 set around the dust collector hood 11 under the action of the suction fan 3. The smoke and dust flow along the L-shaped air ducts 2, first flowing horizontally and then downward. When passing through the dust filter plate 7, dust and debris can be effectively filtered, and the filtered dust can accumulate on the upper surface of the dust filter plate 7, achieving a highly efficient air purification effect.
[0027] An inspection port 21 is provided on the top surface of the horizontal part of the air duct 2 at a position opposite to the dust filter plate 7, and a sealing plate 4 is provided at the inspection port 21; a lifting mechanism is also installed on the air duct 2, and the lifting mechanism is connected to the frame 6.
[0028] Specifically, the sealing plate 4 includes two horizontally split cover plates 41, and the lifting mechanism includes two sets of horizontally symmetrically arranged linkage swing assemblies 5. Each set of linkage swing assemblies 5 is connected to the corresponding cover plate 41 above. The linkage swing assembly 5 includes a first link 51, a second link 52, a third link 53, a fourth link 54, and a sector gear 56. The first link 51 and the second link 52 are arranged in parallel and located outside the air duct 2. The upper ends of the first link 51 and the second link 52 are rotatably connected to the same straight line on the side of the cover plate 41, and the lower end of the second link 52 is rotatably connected to... On the outer wall of the duct 2, the lower end of the first connecting rod 51 is vertically fixed to the rotating shaft 55, which is rotatably connected to the wall of the duct 2. The center of the sector-shaped gear ring outside the duct 2 is also fixed to the rotating shaft 55. The rotating shaft 55 movably passes through the duct 2 and extends into its interior. The third connecting rod 53 and the fourth connecting rod 54 are movably located inside the duct 2. The lower end of the third connecting rod 53 is vertically fixed to the rotating shaft 55, and the upper end of the third connecting rod 53 is tilted to one side and rotatably connected to the lower end of the fourth connecting rod 54. The upper end of the fourth connecting rod 54 is tilted to the other side and rotatably connected to the frame 6. In specific implementation, the fourth connecting rod 54 of the two connecting rod swing assemblies 5 is connected on the same straight line of the frame 6, and in order not to affect the fit between the frame 6 and the inner wall of the duct 2, the fourth connecting rod 54 is connected to the inner side of the frame 6. The sector gears 56 of the two connecting rod swing assemblies 5 mesh with each other.
[0029] When the dust filter plate 7 needs to be cleaned, maintained, or replaced, the two covers 41 can be pulled horizontally to both sides using the handle 42 on top, causing the two sets of first connecting rods 51 and second connecting rods 52 to rotate and swing, thereby causing the rotating shaft 55 connected to the first connecting rod 51 to rotate. Under the meshing of the two sector gears 56, the two sets of connecting rod swinging components 5 can maintain the consistency of their movements. The third connecting rod 53, which is fixed to the rotating shaft 55, can push the fourth connecting rod 54 to move upward and rotate while swinging to both sides, thereby causing the fourth connecting rod 54 to lift the dust filter plate 7 installed on the frame 6 vertically upward and move it to the maintenance port 21. This eliminates the need for personnel to disassemble the equipment or put their bodies into the air duct 2, thus significantly improving the maintenance efficiency of the dust filter plate 7.
[0030] A limiting groove 22 is vertically formed on the inner wall of the duct 2, and a limiting slider 61 protrudes outward from the side of the frame 6. The limiting slider 61 slides up and down within the limiting groove 22. The cooperation between the limiting groove and the limiting slider 61 can significantly improve the stability of the frame 6 when it moves up and down.
[0031] The tops of the two cover plates 41 are locked together by snap fasteners 43. When the two cover plates 41 are closed, they are fixed by snap fasteners 43, which can significantly improve the ease of opening and closing of the sealing plate 4.
[0032] Two cover plates 41 are provided with sealing components on opposite sides. The sealing components include a sealing strip 411 protruding from the side of one cover plate 41 and a receiving groove 412 formed on the opposite side of the other cover plate 41. The sealing strip 411 and the receiving groove 412 engage with each other. After the two cover plates 41 are mated at the inspection port 21, the engagement of the sealing strip 411 and the receiving groove 412 can significantly improve the sealing performance at the joint of the sealing plates 4, preventing smoke and dust from spreading outward.
[0033] In addition, the opening of the inspection port 21 is provided with a sealing ring that matches the sealing plate 4, thereby improving the sealing performance of the connection between the inspection port 21 and the sealing plate 4.
[0034] When using this invention, the dust and fumes generated during the operation of the gravity compressor gather upwards in the dust collection hood 11. With the action of the suction fan 3, they can be drawn outwards from the surrounding air ducts 2. The horizontally arranged dust filter plate 7 inside the air duct 2 provides efficient filtration and purification, effectively preventing pollution of the working environment. When maintenance of the dust filter plate 7 is required, the buckle 43 is opened, and the cover plate 41 is pulled to both sides. With the coordinated action of the two sets of connecting rod swing assemblies 5, the dust filter plate 7 installed on the frame 6 can be lifted upwards and sent to the maintenance port 21, thus significantly improving the maintenance efficiency of the dust filter plate 7.
