Description

Technical Field

[0001] The utility model relates to the technical field of drying machine drums, in particular to a sandwich type steam drying machine drum. Background Art

[0002] The drum dryer is a product specially designed for drying wood chips and sawdust. The equipment integrates drying, cooling and drying in one. It is more energy-efficient than ordinary dryers and can save energy and drying costs to the maximum extent. It is mainly suitable for drying large particles and high-density materials such as ore powder, coal slime, coal powder, etc. in industries such as sawdust, distiller's grains, and rice husks.

[0003] For example, the patent document with announcement number CN 209399692 U discloses a sandwich steam drying drum, in which the drum body is a sandwich structure, and the internal main shaft and steam conduction and heat dissipation system are both tubular structures, and steam can be passed inside and outside for heat exchange and drying. At the same time, a movable anti-sticking and breaking device is provided on the inner wall of the drum to prevent the material from sticking to the inner wall of the drum. The dryer made of this drum can make full use of the steam heat to dry the sticky and wet materials.

[0004] However, during actual use, this structure can often only perform drum drying operations on the entire material, which causes the steam generated by drying to easily remain inside the drum and cannot be quickly discharged to the outside, affecting the overall drying efficiency. At the same time, the equipment cannot perform more uniform and stable continuous drying processing operations on the material and cannot meet daily use needs. Therefore, it is urgent to design a sandwich steam dryer drum to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a sandwich steam dryer drum to solve the problem that the existing structure proposed in the above background technology can only perform the drum drying operation of the whole material during actual use, resulting in the steam generated by the drying being easily inside the drum and unable to be quickly discharged to the outside, affecting the overall drying efficiency. At the same time, the equipment cannot perform a more uniform and stable continuous drying process of the material and cannot meet the daily use needs.

[0006] To achieve the above object, the utility model provides the following technical solution: a sandwich steam drying drum, comprising an outer drum, one end of the outer drum is fixedly connected to a motor frame, one end of the motor frame is provided with a driving motor, a rotating inner drum is provided inside the outer drum through the driving motor, and an exhaust ring groove is provided between the outer drum and the rotating inner drum;

[0007] A material rack and a base frame, the other end of the outer tube is fixedly connected to the material rack, the bottom end of the outer tube is fixedly connected to the base frame, and a ventilation fan is arranged inside one end of the base frame.

[0008] Preferably, an air uniformity frame is fixedly connected to the surface of the base frame, and exhaust grilles are arranged on both sides of the air uniformity frame.

[0009] Preferably, the inner top wall of the material rack is provided with a movable shaft, the interior of the material rack is movably connected to a side cover via the movable shaft, an air intake valve seat is provided on the front of the side cover, and a dustproof net is fixedly connected to one end of the base frame.

[0010] Preferably, a top end of the outer cylinder is fixedly connected to a gas outlet top frame, and a gas outlet grille is provided on the surface of the gas outlet top frame.

[0011] Preferably, a central air pipe is provided at the inner center of the rotating inner cylinder, and four sides of the central air pipe are fixedly connected with air-uniform side frames.

[0012] Preferably, a drying seat is provided inside the air-uniform side frame, and an exhaust ring core is provided on the inner wall of the rotating inner cylinder.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The sandwich steam drying drum can make the equipment perform more efficient steam circulation drum drying operation by arranging the outer drum, motor frame, driving motor, rotating inner drum, exhaust ring groove, bottom frame, ventilation fan, wind uniformity frame, exhaust grille, air outlet top frame and air outlet grille. In actual use, the staff first puts the materials to be dried into the rotating inner drum inside the outer drum, and then starts the driving motor at one end of the motor frame to drive the rotating inner drum inside the outer drum to rotate. During the rotation, the materials inside the rotating inner drum are fully heated. After the hot drying operation, the steam generated by the drying can pass through the rotating inner cylinder and flow into the exhaust ring groove between the outer cylinder and the rotating inner cylinder. At the same time, the ventilation fan at one end of the base frame is started to exhaust air from the dustproof net. Then the airflow follows the exhaust grilles on both sides of the wind uniformity frame on the surface of the base frame and evenly enters the exhaust ring groove inside the outer cylinder. The air is blown upward from both sides from the bottom, and finally the steam inside the exhaust ring groove is continuously discharged from the exhaust grille of the air outlet top frame at the top of the outer cylinder, thereby improving the equipment's processing effect on the material drying steam and reflecting the practicality of the equipment design.

[0015] The sandwich steam dryer drum further improves the overall use effect of the equipment by means of the outer cylinder, material rack, movable shaft, side cover, air inlet valve seat, dust screen, air outlet top rack, air outlet grille, central air pipe, air uniforming side rack, drying seat and exhaust ring core. In daily use, the staff can quickly open and close the side cover inside the material rack along the movable shaft to carry out the drying material loading and unloading operations. Daily, it is only necessary to connect the hot air flow used for drying to the air inlet valve seat of the side cover, so that the hot air flow is connected and enters the central air pipe inside the rotating inner cylinder, and then the air flow is evenly diverted from the air uniforming side rack to each drying seat, so as to realize the uniform drying operation of the material inside the rotating inner cylinder. At the same time, the exhaust ring core on the inner wall of the rotating inner cylinder can ensure the rapid separation and discharge operation of the steam generated by drying, which reflects the comprehensiveness of the equipment design.
