Description

Technical Field

[0001] The present application relates to the technical field of drying mechanical equipment, and in particular to a disc dryer. Background Art

[0002] The disc dryer is a highly efficient conduction-type continuous drying equipment, which has the characteristics of high thermal efficiency, low energy consumption, small footprint, simple configuration, convenient operation and control, and good operating environment. The wet material is continuously added from the feeder to the first drying disc on the upper part of the dryer. The rake arm with rakes makes a rotary motion to make the rakes continuously turn the material, so that the material flows along the exponential spiral line over the surface of the drying disc. The material on the small drying disc is moved to the outer edge and falls from the outer edge to the outer edge of the large drying disc below. The material on the large drying disc moves inward and falls from the middle drop port into the next layer of small drying disc. The large and small drying discs are arranged alternately up and down, so that the material can flow continuously through the entire dryer. The dried material falls from the last layer of drying disc to the collecting disc, and is finally moved by the rakes to the discharge port for discharge, completing the material drying.

[0003] The disc dryer in the related art spreads the material on the drying disc by rotating rakes, and dries the material by the temperature of the upper surface of the drying disc. Therefore, it takes a lot of time to dry the material, which affects work efficiency. Summary of the invention

At this time, the material dropped on the small drying plate near the upper end of the shell is gradually moved toward the edge of the small drying plate under the drive of the corresponding rake blade. At this time, the small drying plate dries the material until the material drops from the edge of the small drying plate to the edge of the adjacent large drying plate. At this time, the large drying plate dries the material, and the rake blade corresponding to the large drying plate drives the material to move in the direction close to the driving shaft until it drops from the discharge port to the next small drying plate until the drying is completed, so that the small drying plate, the large drying plate and the rake blade rotate simultaneously and in the opposite direction, thereby improving work efficiency.

At this time, the driving rod drives the rake blades to rotate and push the material to the edge of the small drying plate, and the small drying plate rotates in the opposite direction. The driving component drives the rotating rod to drive the tipping hopper to rotate along the circumference of the cross section of the rotating rod, so that the material on the small drying plate is brought into the tipping hopper and thrown onto the small drying plate, so that the material that is not in direct contact with the small drying plate is turned over to contact with the small drying plate, thereby improving the material drying efficiency.

The diameter of the small drying plates 2 is smaller than the inner diameter of the shell 1, and large drying plates 3 are provided on the lower side of the small drying plates 2, which are flush with and correspond to the small drying plates 2. The diameter of the large drying plates 3 is equal to the inner diameter of the shell 1, and a feeding port 31 is provided at the center of the large drying plates 3. Electric heating wires (not shown in the figure) are laid in the small drying plates 2 and the large drying plates 3. Figure 2 The small drying plate 2 and the large drying plate 3 are both provided with a plurality of rake arms 21 uniformly distributed along the circumferential direction of the rotation axis of the shell 1 on the upper side. In the embodiment of the present application, two rake arms 21 are provided, and the lower side of the rake arms 21 is provided with a plurality of inclined rake leaves 211 uniformly distributed along the length direction of the rake arms 21.

The lower end of the drive shaft 4 passes through the housing 1 and is equipped with a motor 41 that is fixedly connected to the bottom plate 11. The housing 1 is provided with a rotating assembly 5 that drives the small drying plate 2 and the large drying plate 3 to rotate simultaneously, and the rotation direction of the small drying plate 2 and the large drying plate 3 is opposite to the rotation direction of the drive shaft 4.

[0037] The material enters the feed pipe 12 and moves along the multiple discharge ports 122 at the lower end of the feed pipe 12 to the small drying plate 2 near the upper end of the shell 1 under the drive of the falling star plate. The driving shaft 4 is driven by the motor 41 to drive the rake arm 21 to rotate at the same time and drive the rake blades 211 to rotate, and the rotating component 5 drives the small drying plate 2 and the large drying plate 3 to rotate in the opposite direction relative to the driving shaft 4 at the same time. At this time, the material dropped on the small drying plate 2 near the upper end of the shell 1 is gradually driven by the corresponding rake blades 211 to move toward the edge of the small drying plate 2. At this time, the small drying plate 2 dries the material until the material falls from the edge of the small drying plate 2 to the edge of the adjacent large drying plate 3. The large drying plate 3 dries the material, and the rake blades 211 corresponding to the large drying plate 3 drive the material to move toward the direction close to the driving shaft 4 until it falls from the discharge port 31 to the next small drying plate 2 until the drying is completed, so that the small drying plate 2, the large drying plate 3 and the rake blades 211 rotate simultaneously and in the opposite direction, thereby improving work efficiency.

[0038] Reference Figure 2 and Figure 3 The rotating assembly 5 includes a vertical rotating ring 51 inserted on the inner wall of the housing 1. The height of the rotating ring 51 is less than the height of the inner wall of the housing 1. The inner wall of the housing 1 is provided with a rotating groove 16 adapted to the rotating ring 51.

[0039] The lower end of the rotating ring 51 is fixedly connected with a disc 53 which is sleeved on the driving shaft 4 and is rotatably connected with the driving shaft 4. The disc 53 is rotatably connected with the inner side wall of the housing 1, and the middle part of the lower side of the disc 53 is fixedly connected with a vertical connecting ring 54 which is sleeved on the driving shaft 4 and is rotatably connected with the driving shaft 4. The lower end of the connecting ring 54 passes through the housing 1, and the housing 1 is provided with a rotating member 55 which drives the connecting ring 54 to rotate. A connecting port 531 is provided on one side of the disc 53, and the blocking member 14 includes a blocking plate 141 which is inserted into the side wall of the disc 53 and blocks the connecting port 531. The blocking plate 141 is slidably connected with the disc 53, and a hydraulic cylinder 142 which is fixedly connected with the inner side wall of the disc 53 is installed on one side of the blocking plate 141.

[0041] The motor 41 drives the driving shaft 4 and the first gear 551 installed on the output shaft of the motor 41 to rotate. At this time, the second gear 552 rotates with the first gear 551 and drives the connecting ring 54 and the rotating ring 51 to rotate through the installation shaft 553 and the first belt 554. The rotation directions of the first gear 551 and the second gear 552 are opposite, so that the small drying plate 2, the large drying plate 3 and the rake 211 rotate at the same time, and the small drying plate 2 and the large drying plate 3 rotate in the opposite direction to the rake 211, thereby reducing the time for the material to pass through each small drying plate 2 and the large drying plate 3 and be dried, thereby improving work efficiency.

One side of the rotating rod 6 is fixedly connected to a tipping hopper 61 arranged along the length direction of the rotating rod 6, and the side wall of the tipping hopper 61 is laid with an electric heating wire (not shown in the figure). When the tipping hopper 61 is located at the lower side of the corresponding rotating rod 6, the opening of the tipping hopper 61 faces the corresponding rake arm 21.

[0043] The ends of the rotating rods 6 located on the same straight line that are close to each other are inserted into the driving shaft 4 and are installed with a horizontal mounting rod 62. The ends of the mounting rods 62 that are away from the moving rod are fixedly connected with a vertical first bevel gear 63, and the upper sides of the oppositely arranged first bevel gears 63 are meshed with the same horizontal second bevel gear 64. A driving assembly 7 is provided in the driving shaft 4 for driving the second bevel gear 64 to rotate simultaneously. At this time, the tipping hopper 61 rotates along the circumference of the corresponding rotating rod 6.

[0044] The material moves to the small drying plate 2 near the upper end of the shell 1. At this time, the driving rod 71 drives the rake blade 211 to rotate and push the material to the edge of the small drying plate 2, and the small drying plate 2 rotates in the opposite direction. The second bevel gear 64 is driven by the driving component 7 to drive the first bevel gear 63, the mounting rod 62 and the rotating rod 6 to drive the tipping hopper 61 to rotate along the circumferential direction of the cross section of the rotating rod 6, so that the material on the small drying plate 2 is brought up to the tipping hopper 61 and thrown onto the small drying plate 2, so that the material that is not in direct contact with the small drying plate 2 is turned over to contact with the small drying plate 2, thereby improving the material drying efficiency. When the material is in the tipping hopper 61, the side wall of the tipping hopper 61 also dries the material. The tipping hopper 61 on the large drying plate 3 dries the material in the same way, which is further convenient for improving the material drying efficiency.

A driving member 72 that drives the driving rod 71 to rotate is provided on the rotating ring 51.

[0046] The driving member 72 includes a third gear 721 sleeved and fixedly connected to the upper end of the driving rod 71, and a gear ring 722 with teeth located on the inner side wall is sleeved on the outer side of the lower end of the feeding tube 12, and both sides of the gear ring 722 are fixedly connected to fixed rods 723, and the ends of the fixed rods 723 that are away from each other are fixedly connected to the inner side wall of the upper end of the rotating ring 51. A fourth gear 724 meshing with the third gear 721 is rotatably connected to one side of the inside of the feeding tube 12, and one side of the fourth gear 724 passes through the side wall of the feeding tube 12 and meshes with the gear ring 722.

[0047] The rotating ring 51 rotates and drives the fourth gear 724 to rotate through the ring gear 722. At this time, the third gear 721 meshing with the fourth gear 724 drives the driving rod 71 to rotate with the fourth gear 724, so that the driving rod 71 drives the moving rod to rotate through the first bevel gear 63, the second bevel gear 64 and the mounting rod 62, so that the materials on the small drying plate 2 and the large drying plate 3 can be turned over, thereby improving the material drying efficiency.

[0048] Reference Figure 3The cross section of the mounting rod 62 is square, and the end of the mounting rod 62 away from the corresponding first bevel gear 63 is inserted and slidably connected with the corresponding rotating rod 6.

[0049] The driving rod 71 drives the moving rod to rotate through the mounting rod 62 and at the same time drives the cam 82 to rotate, so that the cam 82 cooperates with the spring 621 and drives the sliding plate 81 to drive the corresponding moving rod to reciprocate along the length direction of the corresponding mounting rod 62, so that the material in the tipping hopper 61 can move along the length direction of the tipping hopper 61 and contact the side wall of the tipping hopper 61, so that the material can be dried and the material drying efficiency can be improved.

The lower end of the other side of the housing 1 is plugged and fixedly connected with a vertical exhaust pipe 18 communicating with the cavity 161. Hot air enters the cavity 161 through the air intake pipe 17 and is discharged through the exhaust pipe 18. An exhaust fan 9 for driving the hot air in the cavity 161 to be discharged is rotatably connected inside the exhaust pipe 18. A control member 91 for driving the exhaust fan 9 to rotate is provided on the mounting shaft 553. The control member 91 includes a vertical control shaft 911 whose upper end is fixedly connected to the axis of the exhaust fan 9. The lower end of the control shaft 911 is located outside the exhaust pipe 18, and a second belt 912 connecting the control shaft 911 and the mounting shaft 553 is installed between the control shaft 911 and the mounting shaft 553.

[0051] The hot air is introduced into the cavity 161 through the air inlet pipe 17. At this time, the second gear 552 rotates and drives the control shaft 911 through the second belt 912 to drive the exhaust fan 9 to rotate, so that the exhaust fan 9 can discharge the hot air in the cavity 161, improve the efficiency of hot air moving and filling the cavity 161, and then facilitate rapid heating of the rotating ring 51 and enable the rotating ring 51 to heat the inside of the shell 1, thereby improving the material drying efficiency.

[0052] The implementation principle of a disc dryer in the embodiment of the present application is as follows: the motor 41 drives the driving shaft 4 and the first gear 551 installed on the output shaft of the motor 41 to rotate, and at this time, the second gear 552 rotates with the first gear 551 and drives the connecting ring 54 and the rotating ring 51 to rotate through the installation shaft 553 and the first belt 554, and the rotation directions of the first gear 551 and the second gear 552 are opposite, so that the small drying plate 2, the large drying plate 3 and the rake 211 rotate at the same time, and the small drying plate 2 and the large drying plate 3 rotate in the opposite direction to the rake 211, thereby reducing the time for the material to pass through each small drying plate 2 and the large drying plate 3 and be dried, thereby improving work efficiency.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
