[0028] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0029] like Figures 1 to 11 As shown, the dust recovery device for glutinous rice flour processing according to the embodiment of the present invention comprises a shell 1, a partition 2, an extrusion plate, a filter body 4 and a second driving component.

[0030] like Figures 1 to 5 As shown, the partition 2 is fixed in the shell 1, and the extrusion plate is slidably installed in the shell 1, and the extrusion plate is located below the partition 2. The partition 2 and the extrusion plate divide the internal space of the shell 1 into an exhaust chamber 11, an air intake chamber 12 and an extrusion chamber 13 from top to bottom. The shell 1 is provided with an air inlet 14 connected to the air intake chamber 12, and the shell 1 is also provided with an exhaust port 15 connected to the exhaust chamber 11.

[0031] The filter body 4 is arranged in the air inlet chamber 12. The filter body 4 is a cylindrical structure and is rotatably mounted on the partition 2. The circumferential surface of the filter body 4 is evenly distributed with air holes, which can allow gas to pass through and can block dust outside the filter body 4. The air outlet 41 of the filter body 4 is arranged at the upper end of the filter body 4 and is connected to the exhaust chamber 11. In this embodiment, there are four filter bodies 4 in the air inlet chamber 12, and the four filter bodies 4 are symmetrically distributed in pairs.

[0032] The shell 1 is provided with a driving component 1 for driving the four filter bodies 4 to rotate. The driving component 1 includes a motor 191, a gear 192 and four gear rings 93. The four gear rings 93 are respectively fixedly installed at the upper ends of the four filter bodies 4. The gear 192 is meshed with the four gear rings 93 at the same time. The motor 191 is fixedly installed on the upper part of the shell 1, and its output end is fixedly connected to the gear 192. The operation of the motor 191 is controlled. Through the meshing of the gear 192 and the gear ring 93, the four filter bodies 4 can be driven to rotate simultaneously, wherein the gear 192 and the gear ring 93 are both located in the exhaust chamber 11.

[0033] A scraper assembly is provided on the peripheral side of the filter body 4, and the scraper assembly includes an arc plate 61 and a spiral blade 62 arranged on the inner side of the arc plate 61. The arc plate 61 is fixedly connected to the partition 2 and is located on the side of the filter body 4 away from the air inlet 14. The spiral blade 62 is in contact with the outer peripheral surface of the filter body 4, and the cross-section of the arc plate 61 can be a semicircular structure.

[0034] After the dust-containing gas enters the air inlet chamber 12 through the air inlet 14, the filter body 4 can block the dust therein, and the gas will enter the filter body 4 through the air holes on the peripheral surface of the filter body 4, and then enter the exhaust chamber 11 through the upper air outlet 41, and finally be discharged from the shell 1 through the exhaust port 15. In the above process, the dust will adhere to the outer peripheral surface of the filter body 4. At this time, the control motor 91 is operated to drive the filter body 4 to rotate. The spiral blade 62 located between the arc plate 61 and the filter body 4 will scrape off the dust adhered to the outer peripheral surface of the filter body 4, and the scraped dust can gradually slide downward along the spiral direction of the spiral blade 62, so that the outer peripheral surface of the filter body 4 can be cleaned in time to ensure the filtering effect of the filter body 4.

[0035] like Figures 2 to 6 As shown, the present embodiment also includes a knocking assembly, which includes a movable block 63, an elastic member 64 and a fixed block 65. The movable block 63 is arranged at the bottom end of the arc plate 61 and the filter body 4, and the movable block 63 is connected to the arc plate 61 for sliding up and down. The elastic member 64 is arranged between the movable block 63 and the arc plate 61, and can apply an upward elastic force to the movable block 63. The fixed block 65 is fixedly installed at the bottom of the filter body 4. When the fixed block 65 rotates with the filter body 4, it can stop with the movable block 63, and the side of the movable block 63 facing the fixed block 65 is an inclined surface.

[0036] Specifically, a guide rod 631 is fixedly connected to the upper part of the movable block 63, and the guide rod 631 is movably inserted into the curved plate 61 from the bottom end of the curved plate 61. The elastic member 64 can be a spring, and its upper and lower ends are respectively fixedly connected to the curved plate 61 and the movable block 63, so that when the movable block 63 moves downward and the elastic member 64 is stretched, the elastic member 64 will apply an upward elastic force to the movable block 63, and the fixed block 65 can rotate synchronously with the filter body 4, and the movable block 63 is located on the rotation trajectory of the fixed block 65, so that when the fixed block 65 rotates with the filter body 4, it can stop with the movable block 63, and the side of the fixed block 65 facing the movable block 63 can also be an inclined surface.

[0037] When the filter body 4 rotates, the fixed block 65 will rotate synchronously with the filter body 4. When the fixed block 65 and the movable block 63 abut against each other, under the action of the inclined surfaces on the fixed block 65 and the movable block 63, the fixed block 65 will push the movable block 63 to move downward, and the elastic member 64 will be stretched. When the fixed block 65 passes over the movable block 63, the movable block 63 will move upward under the pull of the elastic member 64, and will knock the filter body 4 and the arc plate 61, so that the dust scraped off by the spiral blade 62 and the dust adhered to the filter body 4 can fall, thereby facilitating dust collection.

[0038] like Figures 1 to 11 As shown, for ease of understanding, the length direction of the shell 1 is defined as the left-right direction, and the width direction of the shell 1 is defined as the front-back direction. The driving assembly has two groups, and is respectively arranged on the left and right sides of the extrusion plate.

[0039] The second driving component includes a rotating shaft 51, a threaded sleeve 52, a moving member 53 and an elastic member 54. The rotating shaft 51 is vertically rotatably installed on the shell 1. The threaded sleeve 52 is sleeved on the outer peripheral side of the rotating shaft 51. The threaded sleeve 52 can rotate synchronously with the rotating shaft 51, and the threaded sleeve 52 can move up and down relative to the rotating shaft 51. A reciprocating thread is provided on the outer peripheral surface of the threaded sleeve 52. The moving member 53 is fixedly connected to the extrusion plate, and the thread is matched at the reciprocating thread. The elastic member 54 is arranged between the threaded sleeve 52 and the shell 1, and can apply a downward thrust to the threaded sleeve 52. When the extrusion plate moves up with the moving member 53, a channel for material to fall can be formed on the extrusion plate, and when the extrusion plate moves down with the moving member 53, the channel on the extrusion plate will be closed.

[0040] Specifically, the drive assembly 2 has two groups, and the two groups of drive assembly 2 are respectively arranged on the left and right sides of the shell 1. The upper ends of the two rotating shafts 51 in the two drive assemblies 2 are fixedly installed with gears 2 55. The two gears 2 55 are connected by a synchronous belt 56, and a motor 2 57 is fixedly installed on the upper part of the shell 1. The output end of the motor 2 57 is fixedly connected to one of the gears 2 55. Therefore, by controlling the operation of the motor 2 57, the two rotating shafts 51 can be driven to rotate.

[0041] A vertical groove 521 is provided on the inner side surface of the threaded sleeve 52, and a limit key 511 is fixedly provided on the side surface of the rotating shaft 51. The limit key 511 slides up and down in the vertical groove 521, so that the threaded sleeve 52 can rotate synchronously with the rotating shaft 51, and the threaded sleeve 52 can move up and down relative to the rotating shaft 51. The elastic member 54 can be a spring, and its upper and lower ends are respectively connected to the shell 1 and the threaded sleeve 52, and the threaded sleeve 52 can rotate relative to the elastic member 54.

[0042] like Figure 2As shown, the extrusion plate includes two positioning frames 31 arranged along the length direction of the shell 1, and a plurality of plate bodies 32 arranged between the two positioning frames 31. The plurality of plate bodies 32 are arranged along the width direction of the shell 1. Both ends of the plate bodies 32 are rotatably connected to the two positioning frames 31 respectively. The positioning frames 31 are fixedly connected to the moving parts 53. Specifically, the two positioning frames 31 are respectively arranged on the left and right sides of the shell 1, and are respectively fixedly connected to the two moving parts 53. The plurality of plate bodies 32 are arranged along the front-to-back direction. When the moving part 53 moves up and down, the positioning frames 31 and the plate bodies 32 can be driven to move up and down.

[0043] like Figure 2 , Figure 7 and Figure 8 As shown, the rotation control assembly includes a rack 71, a gear three 72 and a pressing piece 73. The rack 71 is slidably installed in the positioning frame 31 and can slide along the width direction of the shell 1. A gear three 72 is fixedly installed at the end of each plate body 32, and the gear three 72 is coaxially arranged with the rotation center of the plate body 32. Each gear three 72 is meshed with the rack 71. The pressing piece 73 is located above the extrusion plate and is fixedly connected to the threaded sleeve 52.

[0044] Specifically, the rack 71 is arranged in the left positioning frame 31, and the length direction of the rack 71 extends forward and backward. The gear is fixedly connected at the rotation center of the left side of the plate body 32. A plurality of torsion springs 74 are provided in the positioning frame 31 on the right side of the plate body 32. The plurality of torsion springs 74 are installed one by one at the rotation center of the right ends of the plurality of plate bodies 32. When the plate body 32 rotates, the torsion spring 74 can store force, and the torsion spring 74 in the stored force state can cause the rotated plate body 32 to reset.

[0045] When dust is recovered, the dust scraped off by the spiral blade 62 will gradually slide down along the spiral direction of the spiral blade 62 to the extrusion plate. At this time, the control motor 2 57 is operated to drive the shaft 51 to rotate, and the shaft 51 will drive the threaded sleeve 52 to rotate. Since the elastic member 1 54 applies a downward thrust to the threaded sleeve 52, the moving member 53 is threadedly engaged with the threaded sleeve 52. When the threaded sleeve 52 rotates, the moving member 53 will move upward first and drive the extrusion plate to move upward. When the extrusion plate moves upward until the lower pressing member 73 contacts the plate body 32, as the extrusion plate continues to move upward The pressing member 73 pushes the plate body 32 to rotate, and the rotating plate body 32 drives the gear three 72 connected thereto to rotate. Through the meshing of the gear three 72 and the rack 71, the rack 71 moves in the front and rear directions, and the moving rack 71 causes the remaining gear three 72 to rotate, thereby driving the multiple plate bodies 32 to rotate synchronously. When the plate body 32 rotates, the torsion spring 74 accumulates force, and when the multiple plate bodies 32 on the extrusion plate rotate, multiple discharge channels are formed on the extrusion plate. At this time, the dust falling on the extrusion plate will fall to the bottom of the extrusion chamber 13 through the discharge channels.

[0046] Since a reciprocating thread is provided on the outer circumferential surface of the threaded sleeve 52, that is, the outer circumferential surface of the threaded sleeve 52 has two thread grooves with the same pitch and opposite rotation direction, and the two thread grooves are connected, as the rotating shaft 51 drives the threaded sleeve 52 to continue to rotate, when the moving member 53 moves to the top of the reciprocating thread, as the threaded sleeve 52 continues to rotate, the moving member 53 will move downward and drive the extrusion plate to move downward. When the pressing member 73 is out of contact with the plate body 32, the extrusion plate will be reset under the action of the torsion spring 74 until the extrusion plate returns to a horizontal state, and when the moving member 53 moves down to the bottom end of the reciprocating thread, as the threaded sleeve 52 continues to rotate, the moving member 53 will move upward again and drive the extrusion plate to move upward.

[0047] Among them, when the moving part 53 drives the extrusion plate to move downward, when a certain amount of dust accumulates at the bottom of the extrusion chamber 13, the downward extrusion plate will press down the dust. In the process of the extrusion plate extruding the dust, the downward movement speed of the extrusion plate will slow down, the threaded sleeve 52 will move upward, and the elastic member 54 will be gradually compressed. When the moving part 53 moves to the bottom end of the reciprocating thread, the extrusion plate can gradually compact the dust at the bottom of the extrusion chamber 13. As the threaded sleeve 52 continues to rotate, the moving part 53 will drive the extrusion plate to move upward. As the threaded sleeve 52 continues to rotate, the dust can gradually fall into the extrusion chamber 13. The threaded sleeve 52 will gradually move upward, and the extrusion plate will periodically compact the dust in the extrusion chamber 13. When the compacted dust in the extrusion chamber 13 reaches a set amount, the driving part 2 is stopped, and the compacted dust in the extrusion chamber 13 can be discharged.

[0048] like Figure 3 As shown, two rotatable bottom plates 16 arranged along the length direction of the shell 1 are provided at the bottom of the extrusion chamber 13. Specifically, the two bottom plates 16 are arranged along the left-right direction, and the opposite outer ends of the two bottom plates 16 are rotatably connected to the shell 1. The shell 1 is provided with a motor 3 85 for driving the bottom plates 16 to rotate. When the compacted dust in the extrusion chamber 13 reaches a set amount, the motor 3 85 is controlled to drive the bottom plates 16 to rotate, so that the bottom of the extrusion chamber 13 can be opened and the compacted dust can be discharged.

[0049] like Figure 3As shown, the material discharge control assembly includes a movable plate 81, a trigger member 82, a reinforcement member 83 and an elastic member 84. The movable plate 81 has two, and the two movable plates 81 are arranged along the width direction of the shell 1 and distributed on both sides of the extrusion plate. The trigger member 82 is fixedly mounted on the upper part of the movable plate 81 and can be movably inserted into the shell 1. The end of the trigger member 82 facing the inner side of the shell 1 is a V-shaped structure or an arc structure. The reinforcement member 83 is fixedly mounted on the lower part of the movable plate 81 and can be movably inserted into the shell 1. When the reinforcement member 83 is inserted into the shell 1, it can stop at the bottom of the bottom plate 16. The elastic member 84 is arranged between the movable plate 81 and the shell 1, and can apply an elastic thrust toward the inner side of the shell 1.

[0050] Specifically, a receiving cavity 17 is provided in the side walls on the front and rear sides of the shell 1, and two movable plates 81 are respectively slidably installed in the two receiving cavities 17, and the movable plates 81 can slide in the front and rear directions. The trigger member 82 is located above the extrusion plate. The length direction of the reinforcement member 83 extends along the left and right directions, and the reinforcement member 83 can stop at the lower part of the two bottom plates 16 to support the bottom plates 16. The elastic member 84 can be a spring, and its two ends are respectively fixedly connected to the movable plate 81 and the shell 1.

[0051] When the dust falls into the extrusion chamber 13 and the extrusion plate moves up and down periodically to compact the gradually increasing dust in the extrusion chamber 13, the threaded sleeve 52 will also gradually move upward. When the dust in the extrusion chamber 13 gradually increases and the threaded sleeve 52 gradually moves upward, the maximum height to which the extrusion plate can move upward will also gradually increase. When the extrusion plate moves up to contact with the trigger member 82, the compacted dust in the extrusion chamber 13 will reach a set amount. As the extrusion plate continues to move upward, the edge of the extrusion plate pushes the trigger member 82, which will push the trigger member 82 and the moving plate 81 toward the outside of the shell 1, and will drive the reinforcement member 83 to move toward the outside of the shell 1. The elastic member three 84 will be compressed until the reinforcement member 83 is detached from the bottom of the bottom plate 16. At this time, the control motor three 85 drives the bottom plate 16 to rotate, so that the bottom of the extrusion chamber 13 can be opened and the compacted dust can be discharged.

[0052] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
