Description

Technical Field

[0001] The invention relates to the technical field of drying equipment, and in particular to a material guiding component of a disc dryer and an operating method thereof. Background Art

[0002] In the disc dryer, the movement of the rakes and the disc is closely coordinated and mutually coordinated to achieve continuous and efficient drying of wet materials. A heating medium (such as saturated steam, hot water and heat transfer oil) is introduced into the hollow disc, and the heating medium enters from one end of the disc and is discharged from the other end. Through the metal wall of the disc, the heat is transferred to the material on the disc by conduction. Under the continuous turning and pushing of the rakes, the material moves along the surface of the disc and fully contacts the disc, thereby absorbing heat and being dried. At the same time, moisture escapes from the material and is discharged from the moisture outlet on the top cover or extracted by a vacuum pump. Due to this coordinated movement of the disc and the rakes, the disc dryer can achieve continuous drying of wet materials. The wet material added from the top moves down layer by layer in the dryer and is dried, and finally the dried material is discharged from the bottom.

[0003] A Chinese patent with announcement number CN208968254U discloses a disc dryer for heating a circular loading plate for chemical production. In the scheme of the patent, it can be seen from the attached drawings that different numbers of rakes are installed on loading plate I and loading plate II, respectively.

[0020] A plurality of rake arm mechanisms 5 are respectively arranged on each loading tray 1 and loading tray 2, a plurality of rake leaf mechanisms 6 are installed at the bottom of the rake arm mechanisms 5, a fixing ring 4 fixedly connected to the output shaft 3 is installed on the outer wall of the output shaft 3, and one end of the rake arm mechanisms 5 is installed on the fixing ring 4, and the rake arm mechanisms 5 drive the rake leaf mechanisms 6 to rotate synchronously along the top surface of the loading tray 1 or the loading tray 2 with the drive of the output shaft 3, so as to convey the materials.

By changing the distance between the two adjusting arms 1 52 and coordinating the adjustment of the adjusting shaft 531, the length of the guide frame 53 can be synchronously and appropriately adjusted.

[0022] An L bracket 1 521 is installed on the end wall of the adjusting arm 1 52 away from the adjusting arm 2 54 by bolts, and an L bracket 2 541 is installed on the end wall of the adjusting arm 2 54 by bolts. The L bracket 1 521 and the L bracket 2 541 are located on the same side, and a key shaft 59 is rotatably arranged between the L bracket 1 521 and the L bracket 2 541. A rotating motor 1 is installed on one side wall of the L bracket 2 541 by bolts, and one end of the key shaft 59 is connected to the rotating motor 1 and driven by the rotating motor 1.

[0023] A screw rod 58 is rotatably arranged between the adjusting arm 1 52 away from the adjusting arm 2 54 and the side wall of the adjusting arm 2 54 . A rotating motor 2 is connected to one end of the screw rod 58 to drive the screw rod 58 . The rotating motor 2 is installed between the inner walls of the adjusting arm 2 54 by bolts.

[0024] The fixed shaft 51 is provided with at least three connecting members 55 for sliding adjustment. One end of the connecting member 55 is a circular ring structure, and the other end is a strip structure. Figure 2 As shown in the figure, except for a connecting piece 55 closest to the connection position between the fixed shaft 51 and the fixed ring 4, the remaining connecting pieces 55 are all installed with positioning pieces 56 on one side of the circumferential side wall by screws. The positioning piece 56 is an annular electromagnet, and an external power supply electrically connected to the electromagnet is installed on the corresponding connecting piece 55. The external power supply is connected to the controller of the disc dryer through an electrical signal. When the external power supply is started, suction can be generated between the electromagnet and the fixed shaft 51 to fix its position.

[0025] A sleeve fixedly connected to the connecting member 55 is provided between the inner walls thereof, and the screw rod 58 passes through the middle of the sleeve without any contact with the inner wall thereof, and a threaded sleeve fixed to the connecting member 55 is installed between the inner walls of the adjusting arm 1 52 near the adjusting arm 2 54 by means of screws, and the screw rod 58 passes through the threaded sleeve and cooperates with the adjusting arm 2 54 by means of threaded transmission.

[0026] The top walls of the two connecting members 55 on the far side are both provided with linkage handles 57 which are rotatably connected via an axis, and the top walls of the remaining connecting members 55 in the middle are both provided with two linkage handles 57 which are rotatably connected via a coaxial connection, and the ends of the two adjacent linkage handles 57 are also movably connected via an axis, wherein the connection point of the two adjacent linkage handles 57 is located within the extended range of the through hole 511, and the line connecting the connection point and the other two connection points on the two adjacent linkage handles 57 can always form an isosceles triangle.

[0027] It should be further explained that, by fixing one of the adjusting arms 1 52 and the adjusting arm 2 54 so that the distance between them is a constant, by starting the rotating motor 2, the other adjusting arm 1 52 is driven to move and adjust under the action of the threaded sleeve. When moving, the adjusting arm 1 52 synchronously drives the part of the guide frame 53 connected thereto to move together, so that the adjusting shaft 531 can be adjusted according to the moving distance.

[0028] like Figure 2 and Figure 4 As shown, the raking mechanism 6 includes a raking blade 61, a connecting shaft 62, a moving seat 63, a bevel gear 1 64, a bevel gear 2 65 and an L bracket 3 66; The longitudinal section of the movable seat 63 is arranged in an "I" shape, and a connecting shaft 62 for rotational contact with the movable seat 63 passes through the middle of the movable seat 63, a rake blade 61 is installed on the bottom end of the connecting shaft 62 by screws, and a convex shaft with an integral structure is welded on the top end of the connecting shaft 62, a bevel gear 1 64 is fixed to the convex shaft by screws, a bevel gear 2 65 is meshed with one side of the bevel gear 1 64, a rotating ring 651 is installed on the side wall of the bevel gear 2 65 facing the L bracket 3 66 by screws, and an L bracket 3 66 is also arranged between the bevel gear 1 64 and the bevel gear 2 65, the convex shaft is rotatably arranged between the inner walls of one end of the L bracket 3 66, the rotating ring 651 is rotatably arranged between the inner walls of the other end of the L bracket 3 66, an axle seat is installed on the vertical side wall of the movable seat 63 facing the position of the L bracket 3 66 by screws, a support rod is inserted in the axle seat, and the top of the support rod is fixed to the bottom wall of the L bracket 3 66 by screws.

[0029] like Figure 3 As shown, the guide frame 53 is provided with a horizontal through hole 1 and a vertical through hole 2 along its length direction. The through hole 1 is adapted to the movable seat 63, the connecting shaft 62 is adapted to the through hole 2, and both ends of the through hole 2 are arc surfaces matching the connecting shaft 62.

[0030] like Figure 2As shown, the bevel gear 2 65 and the rotating ring 651 are both provided with key holes matching the key shaft 59 , the key shaft 59 passes through the bevel gear 2 65 and the rotating ring 651 , and the key on the key shaft 59 passes through the key hole accordingly.

[0031] In addition, each movable seat 63 is fixed to the end of the adjacent connecting member 55 by screws, and one of the movable seats 63 is fixed to the fixed position of the guide frame 53 by bolts (this fixed position is the position when the movable seat 63 slides to the end of the through hole close to the position of the fixing ring 4).

[0032] It should be further explained that by starting the rotating motor 1, it drives the key shaft 59 to rotate. Since the rotating ring 651 and the bevel gear 2 65 are connected as a whole, and the rotating ring 651 and the L bracket 3 66 are in a rotational connection, under the transmission action of the key shaft 59, the rotating ring 651 and the bevel gear 2 65 rotate synchronously, thereby controlling the rotation adjustment of the bevel gear 1 64, and the bevel gear 1 64 and the rake blade 61 are synchronously connected through the connecting shaft 62 and the cam shaft, so that the rake blade 61 is driven by the bevel gear 1 64 and the angle is also adjusted synchronously.

[0033] like Figure 2-3 as well as Figure 5-6 As shown, the adjustment assembly 7 includes a gear 1 71, a gear 2 72, a gear 3 73, a linkage handle 2 74, a rack 75 and a connecting frame 76; the guide assembly 8 includes a fixing bar 81, a slide seat 82 and a guide rod 83; Gear one 71 is rotatably set on the top surface of adjusting arm one 52 close to adjusting arm two 54 through gear shaft one 711, gear three 73 is rotatably set on the top surface of adjusting arm two 54 through gear shaft three 731, gear two 72 is meshingly set between gear one 71 and gear three 73, and gear shaft one 711 and gear shaft three 731 are both movably connected with linkage handle two 74, and gear shaft two 721 with an "I"-shaped structure passes through the center position of gear two 72, and the other ends of the linkage handles two 74 on both sides overlap above the center position of gear two 72 and are both rotatably set on gear shaft two 721, wherein gear shaft one 711 and gear shaft three 731 always remain in the same straight line direction.

[0034] A rack 75 is slidably arranged between the top surface of the adjusting arm 2 54 and the top surface of the adjusting arm 1 52 opposite to the adjusting arm 2 54. A connecting frame 76 with a "U"-shaped structure is arranged on one end of the rack 75. The connecting frame 76 is fixedly connected to one of the moving seats 63 close to it by bolts. The rack 75 is always in meshing state with the gear 2 72, and the rack 75 is always kept parallel to the axial direction of the fixed shaft 51.

[0035] A fixing strip 81 is installed on the opposite side walls of the adjusting arm 2 54 and the adjusting arm 1 52 adjacent to the adjusting arm 2 54 by screws, and a groove is provided on the fixing strip 81, and a guide rod 83 is installed in the groove along its length direction, and a spring is sleeved on the guide rod 83, one end of the spring is fixed to one side end wall of the groove, and a slide seat 82 is slidably provided on the guide rod 83, and the other end of the spring is in contact with the slide seat 82, and a guide block connected to the slide seat 82 is provided on one side wall of the slide seat 82, and a guide groove arranged along the length direction of the fixing strip 81 is provided on the opposite side walls of the adjusting arm 2 54 and the adjusting arm 1 52 adjacent to the adjusting arm 2 54, and the guide block slides in the guide groove, and a slide rod 752 is inserted between the slide seats 82 on both sides, and a connecting block 751 is slidably provided on the slide rod 752, and the connecting block 751 is fixed to the bottom wall of the rack 75 by screws.

[0036] It should be further explained that the screw 58 is driven to rotate by rotating the motor 2, so as to control the threaded sleeve to drive the adjusting arm 1 52 on one side to move and adjust. When moving, the gear 1 71 thereon is driven to rotate synchronously. Through the action of gear meshing, the gear 2 72 and the gear 3 73 rotate synchronously, and the gear 1 71 and the gear 3 73 rotate in the same direction, and the gear 2 72 rotates in the opposite direction. As the gear 2 72 rotates, the rack 75 generates a displacement movement tangential to the tangential direction of the motion trajectory circle of the gear 2 72 due to the rotational movement of the gear 2 72. At the same time, due to the change in the distance between the gear 1 71 and the gear 3 73, the gear 2 72 generates a displacement change relative to its original position (that is, it moves in a straight line direction perpendicular to the rack 75). Since the slide bar 752 connects the slide seats 82 on both sides synchronously, and the slide bar 752 and the rack 75 achieve relative sliding cooperation through the connecting block 751, When gear 72 is in a stationary position and rotates in place, rack 75 drives connecting block 751 to slide back and forth on slide bar 752. When the position of gear 72 changes, with the elastic effect of the spring on guide rod 83, when gear 2 72 moves to the side away from the spring due to the change in the distance between gear 1 71 and gear 3 73, slide 82 will be subjected to the thrust applied by the spring and will synchronously push rack 75 to the side where gear 2 72 is moving, so that the two always remain in a meshing state. When gear 2 72 moves to the side close to the spring due to the change in the distance between gear 1 71 and gear 3 73, rack 75 will be directly pushed to that side by gear 2 72, and rack 75 drives slide 82 to apply extrusion force to the spring, thereby making rack 75 move in two directions due to the rotation and displacement of gear 2 72 in the process of changing the distance between gear 1 71 and gear 3 73.

[0037] When the distance between gear 1 71 and gear 3 73 becomes larger, gear 2 72 moves in the process of Figure 2The rack 75 rotates counterclockwise as shown, so that the rack 75 moves toward the side where the adjusting arm 2 54 is located. At the same time, since the distance between the gear 1 71 and the gear 3 73 becomes farther, the gear 2 72 will also move toward the side where the fixed shaft 51 is located, so that the rack 75 is driven by the slide 82 to move synchronously in the direction of the displacement movement of the gear 2 72 (when the rack 75 moves, the connecting block 751 slides along the slide rod 752, and the slide 82 is exerted by the spring), thereby driving the mobile seat 63 connected thereto to move toward the side away from the adjusting arm 2 54 through the connecting frame 76, and since the adjacent mobile seats 63 are connected by The connecting member 55 and the linkage handle 57 between the connecting members 55 are connected, and the moving seat 63 at one end thereof is fixed, so that when the moving seat 63 fixed to the connecting frame 76 changes position, the remaining moving seats 63 (except the fixed moving seat 63) can move synchronously and shorten the distance between adjacent moving seats 63. After adjusting to the appropriate position, the rotating motor 2 is stopped. When the rotating motor 2 stops working, the external power supply is started and the positioning member 56 enters the working state, so that suction is generated between the positioning member 56 and the fixed shaft 51 at this time, thereby fixing the position of the connecting member 55 and the moving seat 63.

[0038] When the distance between gear 1 71 and gear 3 73 becomes closer, gear 2 72 moves in the process of Figure 2 As shown in the figure, it rotates clockwise. Under the action of the spring, the rack 75 moves to the side away from the adjusting arm 2 54 under the drive of the gear 2 72. At the same time, as the distance between the gear 1 71 and the gear 3 73 becomes closer, the gear 2 72 will also move to the side away from the fixed shaft 51, so that the rack 75 is driven by the slide 82 to move synchronously in the direction of the displacement movement of the gear 2 72 (at this time, due to the movement direction of the slide 82, it exerts a force on the spring), thereby driving the movable seat 63 connected thereto to move toward the side close to the adjusting arm 2 54 through the connecting frame 76, and cooperating with the movement of the linkage handle 1 57 and the connecting member 55, so that the other movable seats 63 except the fixed movable seat 63 are synchronously pulled apart from each other, and the rotating motor 2 is stopped after adjusting to the appropriate position. When the rotating motor 2 stops working, the external power supply is started and the positioning member 56 enters the working state, so that at this time, suction is generated between the positioning member 56 and the fixed shaft 51, thereby fixing the position of the connecting member 55 and the movable seat 63.

[0039] Working principle: First, the rake arm mechanism 5 and the rake leaf mechanism 6 are installed respectively, and the length of the swing arm mechanism and the distance between the rake leaves 61 are adjusted according to the drying requirements. During the adjustment, the rotary motor 2 is started to control the output direction of the screw, so that the adjusting arm 1 52 installed with the threaded sleeve is moved and adjusted accordingly, so that the distance between the adjacent adjusting arm 1 52 and the adjusting arm 2 54 is changed accordingly. When the adjusting arm 1 52 is in motion, the gear 1 71 thereon moves synchronously therewith, and drives the gear 2 72 to rotate and move to one side under the cooperation of the gear 3 73. At the same time, the adjusting shaft 531 on the guide frame 53 of the adjusting arm 1 52 is synchronously extended or retracted during the displacement process to cooperate with the length adjustment of the guide frame 53. After the adjustment is completed, the external power supply is started to generate suction between the positioning member 56 and the fixed shaft 51, so that the position of the connecting member 55 is fixed by adsorption, and the movable seat 63 connected to the connecting member 55 and the position of the rake leaves 61 at the bottom of the movable seat 63 are also fixed at the same time. Then, the disc dryer is started, and the output shaft 3 drives the fixed ring 4 to make a circular motion, thereby driving the lower rake blade 61 to continuously move along the surface of the loading tray 1 or the loading tray 2 through the rake arm mechanism 5, and the material is pushed from the outer edge of the loading tray 2 to the loading tray 1 on the lower layer, and then pushed from the middle position of the loading tray 1 to the loading tray 2 on the lower layer. After multiple cycles, the dried material is discharged through the outlet of the disc dryer.
