Description

Technical Field

[0002] A vibrating fluidized bed dryer, abbreviated as a vibrating fluidized bed, is a new type of highly efficient fluidized drying equipment suitable for drying granular and powdery materials, and has advantages such as easy operation, energy saving, and environmental protection.

[0028] The present invention will be further described below in conjunction with specific embodiments. However, those skilled in the art should understand that the detailed description given here in conjunction with the accompanying drawings is for better explanation. The structure of the present invention necessarily goes beyond these limited embodiments, and for some equivalent replacement schemes or common means, no detailed description will be given herein, but they still fall within the protection scope of this application.

[0029] Figures 1 - 8 This is the best embodiment of the present invention. The following will Figures 1 - 8 further describe the present invention.

[0030] Referring to the Figures 1 - 8 accompanying drawings, the present invention discloses a direct vibration type fluidized bed, which includes a mounting seat 3. The top of the mounting seat 3 is provided with a fluidized bed main body 1 through a plurality of vibration springs 6. A vibration motor 5 is installed on the side of the fluidized bed main body 1. A plurality of air outlets 7 are opened at the top of the fluidized bed main body 1. A plurality of air inlets 10 are opened at the bottom of the fluidized bed main body 1. An upper orifice plate 12 and a lower orifice plate 9 are fixedly installed on the inner walls on both sides of the fluidized bed main body 1. The upper orifice plate 12 is arranged higher than the lower orifice plate 9. A vertical plate 8 is fixedly installed between the adjacent ends of the upper orifice plate 12 and the lower orifice plate 9. A stirring mechanism is installed on the inner wall of the fluidized bed main body 1 above the upper orifice plate 12. A flattening mechanism is fixedly installed on the inner wall of the fluidized bed main body 1 above the lower orifice plate 9. The flattening mechanism is cooperatively installed with the stirring mechanism. A feed hopper 11 is arranged inside the fluidized bed main body 1, and the feed hopper 11 is cooperatively installed with the flattening mechanism.

[0031] With the above structure: Start the vibration motor 5 to make the material move from the upper orifice plate 12 and the lower orifice plate 9 towards the discharge orifice 13. Then, connect the air inlet 10 to the hot gas inlet and the air outlet 7 to the exhaust pipe, so that drying can be carried out during the material transportation process. By starting the leveling mechanism, the stirring mechanism can be driven to agitate the material about to leave the upper orifice plate 12, improving the drying effect. The thickness uniformity of the agitated material is different. After leaving the upper orifice plate 12, it drops onto the lower orifice plate 9. The leveling mechanism cooperates with the vertical plate 8 to flatten the material with different thickness uniformities, so that the material moves on the lower orifice plate 9 with the same thickness, and the thickness of the material can be controlled.

[0032] As Figures 2 - 8 shown, the leveling mechanism includes two mounting plates 28 fixedly installed on the inner walls of both sides of the fluidized bed main body 1. A vertical electric push rod 27 is fixedly installed at the bottom of one of the mounting plates 28. The movable end of the vertical electric push rod 27 is fixedly installed with a cross bar 29. A stopper 30 is fixedly installed at one end of the cross bar 29 away from the vertical electric push rod 27. The top of the stopper 30 is fixedly connected to the side of the feed hopper 11 through a connecting rod 26.

[0033] A horizontal electric push rod 22 is fixedly installed on the vertical side of the other mounting plate 28. The movable end of the horizontal electric push rod 22 is fixedly installed with an L-shaped cross bar 23. A T-shaped hole is opened at the top of the L-shaped cross bar 23. A T-shaped track 24 is slidably installed in the T-shaped hole. A rack 20 is fixedly installed on the side of the T-shaped track 24. L-shaped vertical rods 25 are fixedly installed at the top and bottom of the rack 20. Two positioning holes 17 are opened on the side of the connecting rod 26. One ends of the two L-shaped vertical rods 25 away from the horizontal electric push rod 22 respectively slide through the two positioning holes 17.

[0034] The leveling mechanism further includes a gear 14 rotatably installed on the side of the L-shaped cross bar 23. The gear 14 meshes with the rack 20. An extrusion frame 15 is fixedly installed on the side of the gear 14. The extrusion frame 15 is arranged along the radial direction of the gear 14. Limit blocks 33 are fixedly installed on the inner walls of both sides of the fluidized bed main body 1.

[0035] When it is necessary to dry materials with different thicknesses, the vertical electric push rod 27 can be started in the initial state. The movable end of the vertical electric push rod 27 drives the cross bar 29 and the stopper 30 to move. The stopper 30 drives the feed hopper 11 and the discharge frame to move downward through the connecting rod 26, so that the distance between the cross bar 29 and the lower orifice plate 9 and the distance between the discharge frame and the upper orifice plate 12 can be adjusted. The connecting rod 26 drives the rack 20 to move, and the rack 20 drives the gear 14 to rotate, so that the extrusion frame 15 rotates. When the cross bar 29 moves downward, the distance between the stopper 30 and the lower orifice plate 9 becomes smaller at this time, and the extrusion frame 15 rotates downward, so that when the extrusion frame 15 moves a corresponding distance, the distance that the pressure rod 16 moves downward also increases, so that the distance that the flattening frame 40 and the U-shaped plate 41 move downward in the later stage increases, which is convenient for the flattening frame 40 to be horizontal with the bottom of the stopper 30 in the later stage. Similarly, when the cross bar 29 moves upward, the distance between the stopper 30 and the lower orifice plate 9 becomes larger, and then the extrusion frame 15 will rotate upward, making the distance that the pressure rod 16 moves downward smaller, which is convenient for the flattening frame 40 to be horizontal with the bottom of the stopper 30 in the later stage.

[0036] Limit holes are formed in both of the two limit blocks 33, and limit rods 34 are slidably installed in the two limit holes. A pressure rod 16 is fixedly installed on the side of one of the limit rods 34. One end of the pressure rod 16 extends into the extrusion frame 15, and the pressure rod 16 is coaxially arranged with the gear 14. The flattening mechanism further includes a flattening frame 40 fixedly installed at the bottom ends of the two limit rods 34. The side of the flattening frame 40 is in contact with the side of the stopper 30. Moving grooves are formed in the two side parts of the flattening frame 40 and the side part close to the vertical plate 8, and U-shaped plates 41 are slidably installed in the moving grooves. The side of the U-shaped plate 41 away from the stopper 30 is inclined, that is, the U-shaped plate 41 gradually approaches the vertical plate 8 from top to bottom. The U-shaped plate 41 corresponds to the position of the vertical plate 8. An extrusion groove 39 is formed in the side of the stopper 30 close to the flattening frame 40. The bottom inner wall of the extrusion groove 39 is inclined, that is, the side of the extrusion groove 39 is inclined upward gradually along the direction away from the vertical plate 8. The flattening mechanism further includes a push rod 38 fixedly installed on the inner wall of the U-shaped plate 41 close to the stopper 30. A push block 31 is slidably sleeved on the push rod 38. The top of the push block 31 is fixedly connected to the top inner wall of the flattening frame 40. A return spring 32 is fixedly installed on the side of the push block 31 away from the stopper 30. One end of the return spring 32 away from the stopper 30 is fixedly installed on the inner wall of the U-shaped plate 41. A pressure wheel 37 is rotatably installed at one end of the push rod 38 close to the stopper 30, and the pressure wheel 37 corresponds to the position of the extrusion groove 39.

[0037] The L-shaped cross bar 23 drives the T-shaped track 24 and the rack 20 to move. The rack 20 drives the gear 14 and the extrusion frame 15 to move. The inner wall of the extrusion frame 15 squeezes the pressure-receiving rod 16, so that the pressure-receiving rod 16 moves downward, and then the limit rod 34 moves downward. The downward movement of the limit rod 34 drives the flattening frame 40 to move downward. The movement of the flattening frame 40 drives the U-shaped plate 41 to move downward. When the bottom of the flattening frame 40 is about to be parallel to the bottom of the stopper 30, at this time, the pressure-receiving wheel 37 contacts the inclined inner wall of the extrusion groove 39, so as to squeeze the pressure-receiving wheel 37 to make it move. The movement of the pressure-receiving wheel 37 drives the push rod 38 and the U-shaped plate 41 to move, and the return spring 32 deforms. When the side of the U-shaped plate 41 contacts the side of the vertical plate 8, and at this time the bottom of the flattening frame 40 is parallel to the bottom of the stopper 30, and the side of the U-shaped plate 41 contacts the side of the vertical plate 8, at this time, the uneven-thickness material falling onto the lower orifice plate 9 can be flattened, so that its thickness is uniform.

[0038] Both side portions of the flattening frame 40, both side portions of the stopper 30, and both side portions of the U-shaped plate 41 are in contact with the inner walls on both sides of the fluidized bed main body 1. The advantage of such a setting is to prevent the material from falling from the side portions of the flattening frame 40, the stopper 30, and the U-shaped plate 41.

[0039] As Figure 4 and Figure 6 As shown, the stirring mechanism includes guide rods 18 fixedly installed on the inner walls on both sides of the fluidized bed main body 1. Guide sleeves 19 are slidably sleeved on the guide rods 18. The bottom of the guide sleeve 19 is fixedly installed with stirring plates 35 through a plurality of cylinders 36. The bottom of the stirring plate 35 contacts the top of the upper orifice plate 12. The top of the guide sleeve 19 is rotatably installed with a rotating rod 21. One end of the rotating rod 21 away from the guide sleeve 19 is rotatably installed at the bottom of the L-shaped cross bar 23. There is an included angle between the rotating rod 21 and its moving direction to avoid mechanical dead points. By starting the horizontal electric push rod 22 to make its movable end move back and forth, the L-shaped cross bar 23 first moves closer to and then away from the horizontal electric push rod 22 back and forth. The movement of the L-shaped cross bar 23 drives the rotating rod 21 to rotate. The rotation of the rotating rod 21 drives the guide sleeve 19 to move back and forth on the guide rod 18. The movement of the guide sleeve 19 drives a plurality of cylinders 36 and a plurality of stirring plates 35 to move back and forth, so as to push the material that is about to leave the upper orifice plate 12 back and forth, so as to stir the material.

[0040] As Figure 5 As shown, a discharge frame is fixedly installed at the bottom of the feed hopper 11 and is communicated therewith. The distance between the bottom of the discharge frame and the top of the upper orifice plate 12 is equal to the distance between the bottom of the stopper 30 and the top of the lower orifice plate 9. Both side portions of the discharge frame are in contact with the inner walls on both sides of the fluidized bed main body 1. The thickness of the material can be restricted through the discharge frame.

[0041] As Figure 8As shown, the lower orifice plate 9 is located below the upper orifice plate 12. The horizontal distance between the inclined side of the U-shaped plate 41 and the stopper 30 gradually decreases from bottom to top. When the side of the U-shaped plate 41 contacts the side of the vertical plate 8, the material will fall on the inclined side of the U-shaped plate 41. Then, after the U-shaped plate 41 moves upward, the material continues to fall, without affecting the movement of the material. The horizontal distance between the inclined inner wall of the extrusion groove 39 and the flattening frame 40 gradually increases from bottom to top. By providing the extrusion groove 39, the pressure wheel 37 can be extruded to move it.

[0042] As Figure 1 and Figure 3 shown, a feed pipe 4 is fixedly installed at the top of the fluidized bed main body 1. The bottom end of the feed pipe 4 extends into the fluidized bed main body 1 and corresponds to the position of the feed hopper 11. An outlet hole 13 is formed in the inner wall of one side of the fluidized bed main body 1 away from the feed pipe 4, and the outlet hole 13 corresponds to the position of the lower orifice plate 9. A discharge pipe 2 is fixedly installed on the vertical side of the fluidized bed main body 1, and the discharge pipe 2 corresponds to the position of the outlet hole 13. The outlet hole 13 and the discharge pipe 2 are used for discharging, and the feed pipe 4 is used for feeding.

[0043] The working principle and usage process of the present invention: When in use, feeding can be carried out through the feed pipe 4. The incoming material falls into the feed hopper 11. The material can be guided to the top of the upper orifice plate 12 through the feed hopper 11 and the discharge frame. The discharge frame can limit the thickness of the material. The vibration motor 5 is started to make the material move from the upper orifice plate 12 and the lower orifice plate 9 towards the outlet hole 13. Then, the air inlet 10 is connected to the hot gas inlet, and the air outlet 7 is connected to the exhaust pipe, so that drying can be carried out during the transportation of the material.

[0044] When the material is about to leave the upper orifice plate 12, the material is located at the positions of a plurality of stirring plates 35. The plurality of stirring plates 35 and the stopper 30 are close to the vertical plate 8. By starting the horizontal electric push rod 22 to make its movable end move back and forth, the L-shaped cross bar 23 first approaches and then moves away from the horizontal electric push rod 22 back and forth. The movement of the L-shaped cross bar 23 drives the rotating rod 21 to rotate. The rotation of the rotating rod 21 drives the guide sleeve 19 to move back and forth on the guide rod 18. The movement of the guide sleeve 19 drives the plurality of cylinders 36 and the plurality of stirring plates 35 to move back and forth, so as to push the material that is about to leave the upper orifice plate 12 back and forth, thereby stirring the material. The thickness uniformity of the stirred material is different. After leaving the upper orifice plate 12, it falls onto the lower orifice plate 9.

[0045] During this process, the L-shaped crossbar 23 moves to drive the T-shaped track 24 and the rack 20 to move. The movement of the rack 20 drives the gear 14 and the extrusion frame 15 to move. The inner wall of the extrusion frame 15 squeezes the pressure rod 16, causing the pressure rod 16 to move downward, and then causing the limit rod 34 to move downward. The downward movement of the limit rod 34 drives the flattening frame 40 to move downward. The movement of the flattening frame 40 drives the U-shaped plate 41 to move downward. When the bottom of the flattening frame 40 is about to be parallel to the bottom of the stopper 30, at this time, the pressure wheel 37 contacts the inclined inner wall of the extrusion groove 39, so as to squeeze the pressure wheel 37 to make it move. The movement of the pressure wheel 37 drives the push rod 38 and the U-shaped plate 41 to move towards the vertical plate 8. The return spring 32 deforms. When the side of the U-shaped plate 41 contacts the side of the vertical plate 8, at this time, the bottom of the flattening frame 40 is parallel to the bottom of the stopper 30. At this time, the side of the U-shaped plate 41 contacts the side of the vertical plate 8. At this time, the uneven-thickness material falling on the lower orifice plate 9 can be flattened, so that its thickness is uniform.

[0046] Then the L-shaped crossbar 23 moves in the reverse direction, causing the limit rod 34, the U-shaped plate 41, and the flattening frame 40 to move upward. Under the action of the return spring 32, the U-shaped plate 41 returns to its original state. The side of the U-shaped plate 41 away from the stopper 30 is inclined. When the side of the U-shaped plate 41 contacts the side of the vertical plate 8, the material will fall on the inclined side of the U-shaped plate 41. Then, after the U-shaped plate 41 moves upward, the return spring 32 causes the U-shaped plate 41 to move away from the vertical plate 8, and the material continues to fall, without affecting the movement of the material. An elastic pad can be installed on the side of the U-shaped plate 41 close to the vertical plate 8, so that the vertical plate 8 will not be damaged after the U-shaped plate 41 contacts the vertical plate 8.

[0047] When drying materials with different thicknesses needs to be satisfied, in the initial state, the pressure rod 16 is coaxial with the gear 14. Start the vertical electric push rod 27. The movable end of the vertical electric push rod 27 drives the crossbar 29 and the stopper 30 to move. The movement of the stopper 30 drives the feed hopper 11 and the discharge frame to move downward through the connecting rod 26, so as to adjust the distance between the crossbar 29 and the lower orifice plate 9 and the distance between the discharge frame and the upper orifice plate 12. The movement of the stopper 30 drives the connecting rod 26 to move. The movement of the connecting rod 26 drives the rack 20 to move. The movement of the rack 20 drives the gear 14 to rotate, so that the extrusion frame 15 rotates. When the crossbar 29 moves downward, at this time, the distance between the stopper 30 and the lower orifice plate 9 becomes smaller, and the extrusion frame 15 rotates downward. Thus, when the extrusion frame 15 moves a corresponding distance, the downward movement distance of the pressure rod 16 also increases, so that the downward movement distances of the later flattening frame 40 and the U-shaped plate 41 increase, which is convenient for the bottom of the later flattening frame 40 to be horizontal with the bottom of the stopper 30. Similarly, when the crossbar 29 moves upward, at this time, the distance between the stopper 30 and the lower orifice plate 9 becomes larger, and then the extrusion frame 15 will rotate upward, so that the downward movement distance of the pressure rod 16 becomes smaller when the extrusion frame 15 moves, which is convenient for the bottom of the later flattening frame 40 to be horizontal with the bottom of the stopper 30.

Any person skilled in the relevant art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the technical solution content of the present invention still fall within the protection scope of the technical solution of the present invention.
