Description

Technical Field

[0001] The utility model relates to the technical field of flash drying, in particular to a high-efficiency energy-saving rotary flash drying machine. Background Art

[0002] The hot air of the flash dryer enters the mixing and crushing drying chamber from the bottom of the dryer at a suitable spraying speed through the inlet pipe, which produces strong shear, collision and friction on the material and micronizes it, thus strengthening mass transfer and heat transfer.

[0003] When in use, the traditional rotary flash dryer uses a motor to drive the stirring structure to work. This method not only increases the cost of the entire device, but also requires the use of electricity. In addition, the existing stirring structure generally only rotates to break up the particles, so the actual breaking up effect is poor. Therefore, how to solve this problem is what we need to consider. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a high-efficiency and energy-saving rotary flash dryer. In actual use, the dryer can perform stirring work without the use of a motor, thereby reducing the cost of the device and the actual energy consumption. In addition, when the material is dispersed, the dispersion effect is also better.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A high-efficiency and energy-saving rotary flash dryer comprises a shell, the lower end of which is provided with supporting legs; a hot air mechanism, the hot air mechanism comprising a rotating tube rotatably connected to the inner bottom of the shell, the rotating tube being a tube body sealed at the upper end and conductive at the lower end, a plurality of elbows being equidistantly installed on the outer side of the rotating tube, a high-temperature air pump being installed at the lower end of the shell, the lower end of the rotating tube penetrating the inner bottom of the shell, and being connected to the air outlet of the high-temperature air pump via a rotary joint; and a scattering mechanism, the scattering mechanism being used to scatter materials.

[0007] Preferably, the inner top of the shell is connected to a discharge pipe.

[0008] Preferably, a feeding assembly is installed on the right side of the shell.

[0009] Preferably, the breaking up mechanism comprises a rotating column fixedly connected to the upper end of the rotating tube, and a plurality of rectangular blocks are fixedly connected to the outer side of the rotating column.

[0010] Preferably, each of the rectangular blocks is provided with a sliding groove on the side away from the rotating column, and a sliding plate that can slide left and right is arranged in each of the sliding grooves. The side of each sliding plate close to the rotating column is elastically connected to the inner wall of the sliding groove through a spring, and the other side of each sliding plate is fixedly connected to a rotating bar, and the upper end of each rotating bar is fixedly connected to multiple impact bars.

[0011] Preferably, one end of each rotating bar away from the sliding plate is fixedly connected to a round-headed push rod, a wedge-shaped block is fixedly connected to the inner wall of the shell, and a plurality of the wedge-shaped blocks are matched with corresponding round-headed push rods.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

The dried powder is discharged from the discharge pipe along with the airflow. In the above process, the use of wedge blocks can allow multiple impact bars to rotate while moving back and forth away from and close to the rotating column, further improving the breaking effect.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-Figure 4 , a high-efficiency and energy-saving rotary flash dryer, comprising a shell 1, a supporting leg 2 is installed at the lower end of the shell 1, a discharge pipe 3 is connected to the inner top of the shell 1, and the other end of the discharge pipe 3 is connected to a subsequent bag dust collector, and a feeding assembly 4 is installed on the right side of the shell 1. The feeding assembly 4 is a prior art, which adopts a spiral feeder to achieve uniform feeding;

[0021] The hot air mechanism includes a rotating tube 5 rotatably connected to the bottom of the shell 1. The rotating tube 5 is a tube body with a sealed upper end and a conductive lower end. A plurality of bent tubes 6 are installed at equal intervals on the outer side of the rotating tube 5. Figure 1 As shown, when high-pressure airflow is generated, the reaction force is used to drive the rotating tube 5 to rotate, and then the rotating column 7 is driven to rotate. A high-temperature air pump 9 is installed at the lower end of the shell 1. The high-temperature air pump 9 is a pump body with an electric heating wire. The lower end of the rotating tube 5 passes through the inner bottom of the shell 1. A rotating sealing gasket is also installed at this penetration point, and is connected to the air outlet end of the high-temperature air pump 9 through a rotating joint 10.

[0022] Among them, it also includes a dispersing mechanism, which is used to disperse the materials. The dispersing mechanism includes a rotating column 7 fixedly connected to the upper end of the rotating tube 5, and a plurality of rectangular blocks 11 are fixedly connected to the outer side of the rotating column 7. A slide groove 15 is provided on the side of each rectangular block 11 away from the rotating column 7, and a sliding plate 17 that can slide left and right is arranged in each slide groove 15. The side of each sliding plate 17 close to the rotating column 7 is elastically connected to the inner wall of the slide groove 15 through a spring 16, and the other side of each sliding plate 17 is fixedly connected to a rotating bar 13, and the upper end of each rotating bar 13 is fixedly connected to a plurality of impact bars 14, and the end of each rotating bar 13 away from the sliding plate 17 is fixedly connected to a round head push rod 12, and a wedge block 8 is fixedly connected to the inner wall of the shell 1, and the plurality of wedge blocks 8 are matched with the corresponding round head push rod 12.

[0023] In the utility model, when in use, the staff feeds the material through the feeding assembly 4, and starts the high-temperature air pump 9 at the same time. The high-temperature air pump 9 starts to generate a high-temperature airflow, which is discharged from the rotating tube 5 and finally enters the interior of the shell 1 from multiple curved tubes 6, so that the rotating tube 5 rotates, and the rotating column 7 rotates. The rotating column 7 drives the rectangular block 11, the rotating bar 13 and the impact bar 14 to rotate, and the material is broken up. After the material is broken up, it is evenly contacted with the airflow discharged from the curved tube 6 to achieve drying. The dried powder is discharged from the discharge pipe 3 along with the airflow.

[0024] In the above process, as the round-headed push rod 12 rotates, the round-headed push rod 12 will intermittently contact the inclined surface of the wedge block 8. When the round-headed push rod 12 encounters the wedge block 8, the round-headed push rod 12 and the rotating bar 13 will move away from the interior of the shell 1, thereby allowing the impact bar 14 to move away from the interior of the shell 1 and compress the spring 16 through the sliding plate 17. When the round-headed push rod 12 leaves the wedge block 8, the rotating bar 13 will move back under the elastic action of the spring 16, that is, in the above process, multiple impact bars 14 will also move back and forth away from and close to the rotating column 7, further improving the breaking up effect.

[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
