Description

Technical Field

[0001] The present invention relates to the technical field of dryer discharging, and more particularly to a dryer discharging and turning mechanism. Background Art

[0002] In the final discharge stage of the cross-flow batch circulation dryer, regardless of the top discharge or bottom discharge, the discharge port and the circulation port are connected, that is, a three-way port, which can implement both circulation and discharge functions. To ensure that these two functions do not interfere with each other, a flip mechanism is used for control, so the sealing and stability of the flip mechanism are crucial.

[0003] The turning mechanism in existing cross-flow batch circulation dryers is generally made of stainless steel plates with a thickness of 1.5 to 2 mm. The stainless steel plates are relatively thin and light in weight. The discharge port, circulation port and discharge port are interconnected. The dehumidification fan operates in a negative pressure state. The end of the flap in the turning mechanism away from the rotating shaft is easily driven by the dehumidification fan during operation, which causes the flap to fluctuate, resulting in a loose closure of the flap. When the flap is closed on one side of the discharge port or circulation port, a gap is generated, which will cause the material to be dried to leak from the discharge port or circulation port during the circulation process, seriously affecting the normal drying operation of the material to be dried, resulting in incomplete drying of some of the material to be dried, and causing the material to be dried to easily become moldy during the later storage process. In view of this, a discharge turning mechanism for a dryer is proposed. Summary of the Invention

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. The specific embodiments of the present invention are described in detail below in conjunction with the drawings in the specification.

[0035] The feeding component 1 is used to transport the dry material, the turning component 2 is used to switch the flow direction of the dry material in the feeding component 1, the driving component 4 drives the turning component 2 to turn through the connecting component 3, and the lubricating component 5 is used to lubricate the turning component 2 and the connecting component 3.

[0036] The driving component 4 drives the connecting component 3, the flipping component 2 and the lubricating component 5 to operate, so that the structure on the flipping component 2 is flipped, thereby blocking the through hole in the feeding component 1 and implementing the two functions of circulation and discharge. The connecting component 3 can abut and reinforce the flipping component 2 to prevent the flipping component 2 from fluctuating under the negative pressure state generated by the operation of the dehumidification fan, resulting in a loose closure and the occurrence of a situation, thereby preventing the dried material from leaking from the discharge port 104 or the circulation port 103 during the circulation process, causing the dried material to be easily moldy during the later storage process. When the lubricating component 5 is in operation, it can spray lubricating oil to the connection between the connecting component 3 and the flipping component 2 to reduce the friction between the connecting component 3 and the flipping component 2.

[0037] Example 2: This example is based on the previous example, and differs from the previous example in that: Figure 3 and Figure 4As shown, the feeding assembly 1 includes a feeding pipe 101, a feeding port 102 is provided at the top of the feeding pipe 101, a circulation port 103 is provided at the inclined end of the bottom of the feeding pipe 101, and a discharge port 104 is provided at the lower end of the feeding pipe 101. The feeding port 102, the circulation port 103 and the discharge port 104 are interconnected to form a tee, and two sliding holes 105 are provided on the outer wall of the feeding pipe 101.

[0038] The discharge port 104 is used for discharging the dried material, the circulation port 103 is used for the circulation of the dried material, and the feed port 102 is used for feeding the dried material.

[0039] Example 3: This example is based on the previous example, and differs from the previous example in that: Figure 6 and Figure 7 As shown, the flip assembly 2 includes a rotating shaft 201, one end of the rotating shaft 201 is rotatably connected to the inner wall of the material delivery pipe 101, the other end of the rotating shaft 201 passes through the material delivery pipe 101 and extends to the outside thereof, the outer wall of the rotating shaft 201 is rotatably connected to a connecting sleeve 202, one end of the connecting sleeve 202 passes through the material delivery pipe 101 and is rotatably connected thereto, and two flaps 203 are fixedly provided on the outer wall of the connecting sleeve 202, the two flaps 203 are respectively arranged inside the material delivery pipe 101, and the two flaps 203 are connected to each other. The outer ends of the two flaps 203 are respectively provided with a first inclined surface 204, and the outer ends of the two flaps 203 are both provided with a first arc surface 205. The outer ends of the two flaps 203 are combined to form a cone, and the end faces of the two first arc surfaces 205 are arranged tangentially. A plurality of gears 206 are fixedly provided on the outer end of the rotating shaft 201, and a mounting sleeve 208 is fixedly provided on the circumferential outer wall of the rotating shaft 201. A torsion spring 207 is provided on the circumferential outer wall of the rotating shaft 201, and both ends of the torsion spring 207 are respectively connected and fixed to the connecting sleeve 202 and the mounting sleeve 208.

[0040] The driving assembly 4 can drive the outer gear 206 to rotate. When the gear 206 rotates, it drives the rotating shaft 201 to rotate, and drives the flap 203 to rotate through the rotating shaft 201, thereby blocking the through hole in the feeding assembly 1 and implementing the two functions of circulation and discharge.

[0041] Example 4: This example is based on the previous example, and differs from the previous example in that: Figure 2 、 Figure 5 、 Figure 8 and Figure 9When the cam 310 is in the unlocked position, the locking cam 308 is in the unlocked position, and the winch 308 is in the unlocked position.

[0042] When the gear 206 rotates, under the action of the torsion spring 207, the flap 203 will not flip over, and the two gears 206 on the inner side of the shaft 201 will respectively drive the two first tooth plates 301 to move. When the two first tooth plates 301 move, the connecting plate 302 is driven to move, and the first slider 303 and the second slider 304 are driven to slide along the inner wall of the sliding hole 105 through the two connecting plates 302. The two clamping plates 305 are driven to slide along the inner wall of the feeding pipe 101 through the first slider 303 and the second slider 304. When the clamping plate 305 near one end of the flap 203 slides to the side away from the flap 203, the other clamping plate 305 slides to the position close to the shaft 201, and the driving component 4 continues to operate. At this time, the torsion force on the torsion spring 207 is released, and the shaft 201 is in a state of rotation. The reverse torsional force of the torsion spring 207 drives the two flaps 203 to flip in the opposite direction to seal the upper end of the circulation material port 103. When the flipped flap 203 contacts the inner wall of the other side of the delivery pipe 101, the rotating shaft 201 continues to rotate. Under the torsional force of the torsion spring 207, the rotating shaft 201 continues to rotate. The flap 203 fits tightly with the inner wall of the delivery pipe 101 under the action of torsion. The rotating shaft 201 drives the two clamping plates 305 to continue to move through the gear 206, so that the second inclined surface 306 of the lower end of the clamping plate 305 moving toward the rotating shaft 201 abuts against the first inclined surface 204 at the upper end of the flap 203, which can reinforce the flap 203 and prevent the flap 203 from fluctuating under the negative pressure state generated when the dehumidification fan is running, resulting in a loose closure and the occurrence of problems.

[0043] Example 5: This example is based on the previous example, and differs from the previous example in that: Figure 10As shown, the drive assembly 4 includes a mounting plate 401, which is fixed to the outer wall of the feed pipe 101 by bolts, a hydraulic rod 402 is fixed to the outer side of the mounting plate 401, a connecting rod 409 is fixed to the output end of the hydraulic rod 402, a limiting sleeve 411 is fixed to the outer circumferential wall of the connecting rod 409, a second tooth plate 406 is fixed to the outer circumferential wall of the connecting rod 409, a push block 410 is fixed to the outer circumferential wall of the connecting rod 409, and the second tooth plate 406 is meshed with the outer gear 206;

[0044] The outer wall of the mounting plate 401 is provided with a movable groove 407, the inner wall of the movable groove 407 is slidably connected to a movable block 408, and the outer wall of the movable block 408 is fixedly connected to a push block 410;

[0045] A limiting plate 403 is fixedly provided on the outer wall of the mounting plate 401 , a sliding groove 404 is provided on the top of the limiting plate 403 , a connecting block 405 is slidably connected to the inner wall of the sliding groove 404 , and the top of the connecting block 405 is fixedly connected to the second tooth plate 406 .

[0046] The output end of the hydraulic rod 402 moves telescopically, and at the same time drives the connecting rod 409 to move. The movement of the connecting rod 409 drives the push block 410 to move, so that the push block 410 drives the moving block 408 to slide along the inner wall of the moving groove 407. When the connecting rod 409 moves, it drives the second tooth plate 406 to move, so that the second tooth plate 406 drives the connecting block 405 to slide along the inner wall of the limit plate 403, and the second tooth plate 406 can push the outer gear 206 to rotate.

[0047] Example 6: This example is based on the previous example, and differs from the previous example in that: Figure 11 、 Figure 12 、 Figure 13 and Figure 14 As shown, the lubrication assembly 5 includes a lubrication box 51, the outer wall of the lubrication box 51 is connected and fixed to the feed pipe 101, and the outer wall of the lubrication box 51 is detachably connected to a cover plate 52, the lubrication box 51 and the cover plate 52 are respectively rotatably connected to the rotating shaft 201, the rotating shaft 201 respectively penetrates the lubrication box 51 and the cover plate 52 and extends to the outside thereof, the lubrication box 51 is respectively slidably connected to the two first tooth plates 301, the ends of the two first tooth plates 301 penetrate the lubrication box 51 and extend into the interior thereof, an oil filling pipe 53 is fixedly provided on the outer wall of the lubrication box 51, and a sealing cap 54 is threadedly connected to the outer end of the oil filling pipe 53, an oil spray assembly 55 is installed on the inner wall of the lubrication box 51, a first nozzle 56 and a second nozzle 57 are respectively fixed on the inner wall of the lubrication box 51, the nozzles of the first nozzle 56 and the second nozzle 57 are respectively arranged towards the meshing position of the two first tooth plates 301 and the gear 206, and the oil spray assembly 55 is respectively connected and fixed to the first nozzle 56 and the second nozzle 57;

[0048] The oil injection assembly 55 includes a pressure cylinder 551, the end of the pressure cylinder 551 is fixedly connected to the inner wall of the lubrication box 51, and a connecting rod 553 is slidably connected to the inner wall of the pressure cylinder 551. A piston 552 is fixedly provided at the inner end of the connecting rod 553, and the piston 552 is slidably connected to the inner wall of the pressure cylinder 551. A connecting arm 554 is fixedly provided at the outer end of the connecting rod 553, and the end of the connecting arm 554 is fixedly connected to the second gear plate 406. An oil injection pipe 555 is fixedly provided at the end of the pressure cylinder 551, and an oil suction pipe 556 is fixedly provided at the bottom of the outer wall of the pressure cylinder 551. A one-way valve 557 is fixedly provided on the circumferential outer walls of the oil injection pipe 555 and the oil suction pipe 556.

[0049] When the second gear plate 406 moves, it can drive the connecting rod 553 to move through the connecting arm 554. When the connecting rod 553 moves, it drives the piston 552 to move to the side away from the oil injection pipe 555. At this time, the pressure cylinder 551 sucks the lubricating oil inside the internal lubrication box 51 into the interior through the oil suction pipe 556. When the output end of the hydraulic rod 402 extends outward, the second gear plate 406 slides in the opposite direction. At this time, the piston 552 moves to the side close to the oil injection pipe 555. Through the squeezing of the piston 552, the lubricating oil inside the pressure cylinder 551 can be injected into the first nozzle 56 and the second nozzle 57 respectively through the oil injection pipe 555, so that the lubricating oil in the first nozzle 56 and the second nozzle 57 can be sprayed to the meshing points of the two first gear plates 301 and the two gears 206 respectively, thereby lubricating the structure inside the lubrication box 51 and reducing the friction between the structures.

[0050] When in use, the output end of the hydraulic rod 402 contracts into the cylinder, and at the same time drives the connecting rod 409 to move. The movement of the connecting rod 409 drives the push block 410 to move, so that the push block 410 drives the moving block 408 to slide along the inner wall of the moving groove 407. When the connecting rod 409 moves, it drives the second tooth plate 406 to move, so that the second tooth plate 406 drives the connecting block 405 to slide along the inner wall of the limit plate 403. The second tooth plate 406 can push the outer gear 206 to rotate. When the gear 206 rotates, under the torsion of the torsion spring 207, the flap 203 will not flip over, and the rotating shaft 2 The two gears 206 on the inner side of 01 will respectively drive the two first tooth plates 301 to move. When the two first tooth plates 301 move, they will drive the connecting plate 302 to move. The two connecting plates 302 will respectively drive the first slider 303 and the second slider 304 to slide along the inner wall of the sliding hole 105. The first slider 303 and the second slider 304 will respectively drive the two clamping plates 305 to slide along the inner wall of the feeding pipe 101. When the clamping plate 305 near one end of the flap 203 slides, it slides to the side away from the flap 203, and the other clamping plate 305 slides to a position close to the rotating shaft 201.

[0051] The hydraulic rod 402 pulls the second gear plate 406 to continue moving. At this time, the torsion force on the torsion spring 207 is released. The rotating shaft 201 drives the two flaps 203 to flip in the opposite direction under the action of the reverse torsion of the torsion spring 207 to seal the upper end of the circulation material port 103. When the flipped flap 203 contacts the inner wall of the other side of the material delivery pipe 101, the rotating shaft 201 continues to rotate. Under the torsion force of the torsion spring 207, the rotating shaft 201 continues to rotate. The flap 203 fits tightly with the inner wall of the material delivery pipe 101 under the action of torsion. The rotating shaft 201 drives the two clamping plates 305 to continue moving through the gear 206, so that the second inclined surface 306 of the lower end of the clamping plate 305 moving toward the rotating shaft 201 abuts against the first inclined surface 204 at the upper end of the flap 203, thereby reinforcing the flap 203.

[0052] As the second gear plate 406 moves, it can drive the connecting rod 553 to move via the connecting arm 554. When the connecting rod 553 moves, it drives the piston 552 to move away from the oil injection pipe 555. At this time, the pressure cylinder 551 sucks the lubricating oil inside the internal lubrication box 51 into the interior through the oil suction pipe 556.

[0053] When the output end of the hydraulic rod 402 extends outward, the second gear plate 406 slides in the opposite direction, and the piston 552 moves to the side close to the oil injection pipe 555. The lubricating oil inside the pressure cylinder 551 can be injected into the first nozzle 56 and the second nozzle 57 through the oil injection pipe 555 through the squeezing of the piston 552, so that the lubricating oil in the first nozzle 56 and the second nozzle 57 can be sprayed to the meshing parts of the two first gear plates 301 and the two gears 206 respectively, thereby lubricating the structure inside the lubrication box 51.
