Description

Technical Field

[0001] The utility model relates to the technical field of mechanical engineering, in particular to a rotary drying machine for processing organic fertilizer finished materials. Background Art

[0002] Organic fertilizer is not only rich in nutrients and easy to be absorbed by crops, but also can improve soil and increase crop yields. With the improvement of people's quality of life, higher requirements are placed on the quality of food, and green food is becoming more and more popular. China's utility model patent, authorization announcement number "CN219589348U", discloses a rotary dryer for processing organic fertilizer finished materials. A first rotating shaft and a second rotating shaft are arranged on the upper part of the interior of the shell, and the second rotating shaft is located at the front end of the first rotating shaft. One end of the first rotating shaft and the second rotating shaft both penetrate the sealed bearing on the outer wall of one side of the shell and extend to the outside. An installation slot is provided at the center of one end wall of the first rotating shaft and the second rotating shaft. Air outlets are provided on the outer walls of the first rotating shaft and the second rotating shaft. A sealed bearing is arranged on one side of the interior of the installation slot, and a second connecting pipe is installed in the sealed bearing. The organic fertilizer finished materials can be effectively dried, and dust in the organic fertilizer finished materials can be removed, so that the staff can discharge the dried organic fertilizer finished materials.

[0003] According to the above technical solution, after the staff transports the finished organic fertilizer materials from the feed pipe to the inside of the shell, the fan is started to circulate the air inside the shell and the air inside the box. When the first rotating shaft and the second rotating shaft drive the spiral blades to rotate, the finished organic fertilizer materials can be transported back and forth. However, the above technical solution still has certain defects. For example, the above equipment filters the dust through the plate-type primary air filter inside the box. However, when the plate-type primary air filter needs to be removed for a long time, the staff needs to open the first safety lock and wear safety protective gear to take out the plate-type primary air filter from the inside of the box. This greatly increases the workload of the staff and is complicated to operate, making it inconvenient for the staff to remove the plate-type primary air filter. Utility Model Content

[0034] (2) The organic fertilizer finished material processing rotary dryer uses an exhaust fan to suck the dust generated by the raw materials when they are moving into the interior of the purification box through a hose. The dust is then filtered through a filter plate inside the purification box and then the heating plate is started. The air inside the purification box is heated by the heating plate and then sent into the interior of the drying box through a hose to realize hot air circulation. This reduces the loss of heat, effectively reduces the energy consumption of the equipment, and greatly improves the practicality and effectiveness of the equipment.
