Description

Technical Field

[0001] The invention relates to the technical field of air separators, in particular to a wood fiber air separator. Background Art

[0002] Air separators play an important role in many industrial fields. Air separators are mainly composed of a feeding device, an air separation chamber, a fan, a discharge port and other parts. Its working principle is to use wind power to separate materials of different densities. After the materials enter the air separation chamber through the feeding device, the strong wind generated by the fan blows up the materials. The lighter materials will be blown farther by the wind, and the heavier materials will fall faster. In the field of resource recycling, air separators can effectively separate lightweight recyclables such as plastics and paper from mixed garbage, thereby improving the recycling rate of resources. In mining, it can separate impurities from ore and improve the quality of ore. Air separators have the advantages of simple operation, high separation efficiency, energy saving and environmental protection. It does not require a complex chemical treatment process, but only relies on wind power to achieve separation, reducing pollution to the environment. At the same time, the operating cost of the air separator is relatively low, which can save a lot of production costs for enterprises. In short, air separators, with their unique advantages, provide strong support for the sustainable development of various industries.

[0003] When the feeding speed of wood fiber cannot be controlled during the air separation process, it will bring many disadvantages. Too fast feeding speed may lead to insufficient air separation. The wood fiber and impurities stay in the air separator for too short a time and cannot fully interact with the wind, so that some lighter impurities cannot be effectively separated, reducing the purity of the wood fiber. For example, when producing wood fiber boards, impure wood fibers will affect the quality of the boards, reducing their strength, flatness and other properties. Secondly, it is easy to cause equipment blockage. A large amount of wood fiber quickly flows into the air separator, which may exceed the processing capacity of the equipment and accumulate at the feed port, air duct and other parts, affecting the normal operation of the equipment. This will not only cause production interruptions, but also require time and manpower for cleaning and maintenance, increasing production costs. Summary of the invention

The end of the spring 515 is fixedly connected to the inner surface of the stirring frame 511. By setting the stirring plate 514, the wood fibers in the inner cavity of the processing box 51 can be stirred. The wood fibers agglomerated in the inner cavity of the box 51 are struck and stirred. By setting a spring piece 515, the stirring plate 514 can be pulled, so that when the stirring frame 511 rotates, a certain relative shaking occurs between the stirring plate 514 and the stirring frame 511. The outer surface of the rotating rod 56 is located on one side of the inner cavity of the air separation box 3 and is fixedly connected with a fixing block 516. The side of the fixing block 516 away from the rotating rod 56 is fixedly connected with a supporting rod 517. The end of the supporting rod 517 is fixedly connected with an extruding rod 518. The inner wall of the connecting box 58 is fixedly connected with a blocking mechanism 59. The blocking mechanism 59 includes a limit box 591. The limit box 591 is fixedly connected to the inner wall of the connecting box 58. The inner cavity of the limit box 591 slides The sliding block 592 is dynamically connected. By setting the support rod 517, the squeezing rod 518 can be connected to the fixed block 516. By setting the squeezing rod 518, the blocking mechanism 59 can be intermittently squeezed when the rotating rod 56 rotates, so that the blocking mechanism 59 can guide the wood fibers. By setting the blocking mechanism 59, the wood fibers can be intermittently discharged into the inner cavity of the air separation box 3 during the continuous rotation of the squeezing rod 518 and when being squeezed by the squeezing rod 518. By setting the limit box 591, the sliding block 592 can be limited, so that the sliding block 592 can produce an effect of vertical up and down movement in the inner cavity of the limit box 591. The lower surface of the sliding block 592 is fixedly connected with a first spring 593.The bottom end of the first spring 593 is fixedly connected to the bottom surface of the inner cavity of the limit box 591. By setting the first spring 593, the lower surface of the sliding block 592 can be squeezed, so that the sliding block 592 can always be subjected to an upward squeezing force, and then rebound can be generated after the sliding block 592 moves downward. The side of the sliding block 592 away from the inner wall of the limit box 591 is fixedly connected with a baffle 594. By setting the baffle 594, the opening of the limit box 591 can be blocked when the sliding block 592 moves up and down, thereby preventing wood fibers from entering the inner cavity of the limit box 591 and causing the first spring 593 to be blocked.

By setting the blocking plate 599 and the sealing sheet 5910, when the air pressure in the inner cavity of the air separation box 3 increases, the cushion 597 can be deformed, thereby causing the blocking plate 599 to change its angle, and causing the sealing sheet 5910 to be squeezed against the inner wall of the connecting box 58, thereby preventing the wood fibers from leaking out. When in use, the operator pours the wood fibers to be air-selected into the inner cavity of the feed pipe 52, thereby allowing the wood fibers to enter the inner cavity of the processing box 51. Then, the motor 55 is connected to the power supply and the switch is turned on, so that the rotating rod 56 rotates. When the rotating rod 56 rotates, the stirring frame 511 and the stirring plate 514 will stir the wood fibers in the inner cavity of the processing box 51, so that the clumped wood fibers can be broken up. When the rotating rod 56 rotates and drives the squeezing rod 518 to squeeze the round bar 596, the round bar 596 drives the connecting rod 595 to move downward, thereby causing the sliding block 592 to move downward in the inner cavity of the limit box 591. Since the inner cavity of the connecting box 58 is narrow at the top and wide at the bottom, there is a certain space between the blocking bar 598 and the inner wall of the connecting box 58, thereby causing the wood fibers to leak into the inner cavity of the air separation box 3. When the collecting mechanism 7 is full, the space of the air separation box 3 is in a sealed state.Then the air pressure in the inner cavity of the air separation box 3 increases, which will cause the cushion 597 to deform and the blocking strip 598 to flip upward, and finally the blocking plate 599 and the sealing sheet 5910 to be tightly connected to the inner wall of the connection box 58, thereby preventing the wood fibers from flowing out.

By arranging the second roller 64, when the first roller 510 rotates, the second roller 64 can be driven by the belt 65 to rotate, and finally the crushing cylinder 63 is rotated. When in use, during the process of air separation of wood fibers, the heavier wood fibers will fall to the bottom of the inner cavity of the air separation box 3 and fall into the inner cavity of the crushing box 61. When the rotating rod 56 drives the second roller 64 to rotate, the belt 65 will drive the second roller 64 and the crushing cylinder 63 to rotate, and finally the wood fibers in the inner cavity of the crushing box 61 can be crushed and finally discharged from the slag discharge port 62.

[0023] The third embodiment, as Figure 10-12As shown, the collecting mechanism 7 includes a track frame 71, and the track frame 71 is fixedly connected to the side of the air separation box 3 away from the screen 8. A sliding rod 72 is slidably connected to the inner cavity of the track frame 71, and a connecting block 73 is fixedly connected to the end of the sliding rod 72. A round rod 74 is fixedly connected to the lower surface of the connecting block 73. The lower surface of the track frame 71 is fixedly connected to a limited frame 76, and the round rod 74 is slidably connected to the inner wall of the limited frame 76. The outer surface of the round rod 74 is sleeved with a second spring 75, and the bottom end of the second spring 75 is fixedly connected to the upper surface of the limited frame 76. By setting The track frame 71 can limit the sliding rod 72 so that the sliding rod 72 can move in the inner cavity of the track frame 71, thereby driving the round rod 74 to move. By setting a limit frame 76, the round rod 74 can be limited. By setting a second spring 75, the round rod 74 can be squeezed so that after the round rod 74 moves in the inner cavity of the limit frame 76, the round rod 74 can rebound. The collecting mechanism 7 also includes a discharge pipe 77, which runs through the side of the air separation box 3 away from the screen 8. The end of the sliding rod 72 away from the connecting block 73 is fixedly connected to a connecting frame 78. The connecting frame 78 A blocking plate 79 is fixedly connected to the top, and the blocking plate 79 is frictionally adapted to the outer surface of the discharge pipe 77. By setting the discharge pipe 77, the wood fibers that have been selected by air in the inner cavity of the air separation box 3 can be discharged, so that the wood fibers can be discharged from the air separation box 3 through the discharge pipe 77. By setting a connecting frame 78, it can be connected to the sliding rod 72. By setting the blocking plate 79, when the sliding rod 72 moves downward, the blocking plate 79 can gradually block the opening of the discharge pipe 77. The bottom end of the connecting frame 78 is fixedly connected to a locking sleeve 710, and the inner cavity of the locking sleeve 710 is slidably connected to a locking rod. 711, the lower surface of the locking rod 711 is fixedly connected with a collecting box 712, the outer surface of the collecting box 712 is penetrated by a blocking net 713, the opening of the collecting box 712 is aligned with the opening of the connecting frame 78, and by setting the locking sleeve 710, the locking rod 711 can be limited, so that the locking rod 711 can be connected to the inner cavity of the locking sleeve 710, and then the collecting box 712 can be separated from the connecting frame 78, which is convenient for collecting wood fibers in the inner cavity of the collecting box 712, and by setting the blocking net 713, the collecting box 712 can be connected to the outside air and the wood fibers can be blocked.

[0024] Working principle: The operator connects the blower 11 to the power supply and turns on the switch, so that the external airflow enters the inner cavity of the air separation box 3. Under the action of the airflow, the qualified wood fibers are blown and enter the inner cavity of the collection box 712 through the discharge pipe 77. When the wood fibers in the inner cavity of the collection box 712 accumulate to a certain amount, the collection box 712 will move downward, thereby causing the sliding rod 72 to move downward in the inner cavity of the track frame 71, and finally causing the blocking plate 79 to block the discharge pipe 77, thereby making the inner cavity of the air separation box 3 The operator pours the wood fibers to be air-selected into the inner cavity of the feed pipe 52, and then the wood fibers enter the inner cavity of the processing box 51. Then the motor 55 is connected to the power supply and the switch is turned on, so that the rotating rod 56 rotates. When the rotating rod 56 rotates, the stirring frame 511 and the stirring plate 514 will stir the wood fibers in the inner cavity of the processing box 51, so that the clumped wood fibers can be broken up. When the rotating rod 56 rotates and drives the squeezing rod 518 to squeeze the round bar 596 At this time, the round bar 596 drives the connecting rod 595 to move downward, thereby causing the sliding block 592 to move downward in the inner cavity of the limit box 591. Since the inner cavity of the connecting box 58 is narrow at the top and wide at the bottom, there is a certain space between the blocking bar 598 and the inner wall of the connecting box 58, thereby causing the wood fibers to leak into the inner cavity of the air separation box 3. When the collecting mechanism 7 is full, the space of the air separation box 3 is in a sealed state, thereby causing the air pressure in the inner cavity of the air separation box 3 to increase, causing the soft cushion 597 to deform and causing the blocking bar 598 to flip upward. Rotate, and finally the blocking plate 599 and the sealing plate 5910 are tightly connected to the inner wall of the connecting box 58, so as to prevent the wood fiber from flowing out; in the process of wood fiber air selection, the heavier wood fiber will fall to the bottom of the inner cavity of the air selection box 3, and fall into the inner cavity of the crushing box 61. When the rotating rod 56 drives the second roller 64 to rotate, the belt 65 will drive the second roller 64 and the crushing cylinder 63 to rotate, and finally the wood fiber in the inner cavity of the crushing box 61 can be crushed and finally discharged from the slag discharge port 62.
