Description

Technical Field

[0001] The present invention relates to the technical field of drying, and specifically to a cylindrical drying device. Background Art

[0002] In the processing of agricultural products, drying devices are often required. For different agricultural products, the drying equipment used is quite different. Existing drying devices have dynamic drying and static drying methods. Most static drying methods are sun drying or drying by standing still on a drying rack and passing hot air. These two methods relatively require a large floor area and a long drying time. To improve the drying speed, there is also a relatively faster dynamic drying method, which dries the product by stirring to promote the circulation of air flow inside the product. For example, in the drying of jujubes, the commonly used method is static drying, which also has the common problems of static drying. Although dynamic drying of jujubes can dry a large number of them simultaneously and occupies less space, it is relatively easy to be damaged by being hit during stirring, and the jujubes are stacked on top of each other unevenly, resulting in blocked air circulation, a long drying time, and low efficiency. General drying devices are difficult to evenly disperse jujubes, the hot air flow cannot circulate fully, and the jujubes are easily damaged during stirring. Static drying occupies a large area, the jujubes are not dried comprehensively, and the efficiency is low. Therefore, a cylindrical drying device is needed. Summary of the Invention

The bottom of the drying cylinder is fixedly connected to the base, and the centrifugal drying mechanism is arranged on the drying cylinder; The centrifugal drying mechanism includes a motor, a rotating shaft, and an inner cylinder. The motor is fixedly installed on the drying cylinder. A bearing is arranged on the surface of the drying cylinder. The surface of the rotating shaft is fixedly connected to the inner ring of the bearing. The output shaft of the motor is fixedly connected to one end of the rotating shaft through a coupling. A plurality of dividing ring plates are fixedly connected to the inner wall of the inner cylinder. Several support rods are fixedly connected to the surface of the rotating shaft, and the surface of the support rods is fixedly connected to the surface of the dividing ring plates.

[0005] Preferably, the cross-section of the split ring plate is trapezoidal. A plurality of circles of air guiding ports are formed on the surface of the inner drum, and a circle of air guiding ports is arranged between two adjacent split ring plates. An arc-shaped air guiding plate is fixedly connected to the inner wall of each air guiding port.

[0006] Preferably, the centrifugal drying mechanism further includes a plurality of supporting rods. Grooves are formed on the surface of the split ring plate, and the supporting rods are lapped on the inner walls of the grooves. The supporting rods are circumferentially distributed inside the split ring plate. A plurality of wave springs are fixedly connected between two adjacent supporting rods, and a counterweight ball is fixedly connected to the surface of each wave spring.

[0007] Preferably, the wave springs are located between the split ring plates. A circle of wave springs is arranged between every two split ring plates. The inner wall of the groove is semi-circular, and the diameter of the supporting rod is smaller than the diameter of the groove.

[0008] Preferably, the centrifugal drying mechanism further includes several air guiding plates. An air guiding plate is fixedly connected between two adjacent support rods. The surface of the air guiding plate is arc-shaped, and the inner concave surface has a certain spiral amplitude. A plurality of air discharge ports are formed on the surface of the drying cylinder, and the air guiding plate is made of rubber.

[0009] Preferably, several electric heating rods distributed circumferentially are fixedly connected to the inner wall of the drying cylinder. An annular pipe is fixedly connected to the surface of the drying cylinder. An electric heating ring rod is fixedly connected to the surface of the annular pipe. An air inlet is arranged between the annular pipe and the drying cylinder. A pressure air inlet pipe is sleeved on the surface of the annular pipe.

[0011] (3) Beneficial effects (1) By setting the centrifugal drying mechanism, the present invention can disperse the jujubes to be dried by means of centrifugal force, avoid the stacking of jujubes, enhance the wind force, and promote the rapid circulation of air between the jujubes. Compared with the prior art, it can not only disperse the jujubes, but also enhance the circulation speed of the hot air penetrating the gaps between the jujubes, greatly improving the working efficiency.

[0012] (2) The present invention provides a dividing ring plate. On the one hand, the dividing ring plate can evenly disperse the jujubes and prevent the jujubes from moving sideways when the jujubes rotate rapidly, thereby limiting the range of movement of the jujubes and thus preventing the jujubes from being squeezed and piled up against each other. On the other hand, a gap can be maintained between the jujubes and the inner drum, providing space for the rapid circulation of air, thereby enhancing the air circulation effect and improving the drying efficiency.

[0013] (3) The present invention provides a wave spring. On the one hand, the wave spring increases the friction when it contacts the jujubes, driving the jujubes to rotate along with the inner drum, thereby quickly dispersing the jujubes in a circular shape. On the other hand, under the action of wind force, the wave spring provided with a counterweight ball can continuously vibrate locally, thereby causing the jujubes nearby to vibrate locally, and continuously changing the position and angle of the jujubes. This can avoid the uneven drying caused by uneven heating of the jujubes locally, and can also promote the rapid circulation of wind force.

[0014] (4) The present invention provides an air guide plate. On the one hand, when the jujubes fall off the dividing baffle, the air guide plate can catch the fallen jujubes at a close distance and return the jujubes along the arc surface to the dividing ring plate to avoid the jujubes from being damaged by impact. On the other hand, the air guide plate can guide the hot air blowing through the jujubes to make the hot air swirl, thereby enhancing the drying effect.

[0015] (5) In view of the problem of uneven drying in existing drying devices, the present invention designs a special structure that can evenly disperse the jujubes and enhance the hot air flow rate, thereby effectively solving the problems that the general drying device is difficult to evenly disperse the jujubes, the hot air flow cannot be fully circulated, and the jujubes are easily damaged when being stirred, and the static drying takes up a large area, the jujubes are not dried comprehensively, and the efficiency is low.
