Description

Technical Field

[0001] This utility model relates to the field of organic fertilizer production technology, specifically to an organic fertilizer drying device. Background Technology

[0002] The drying process is crucial in organic fertilizer production. Traditional natural sun-drying is time-consuming, labor-intensive, susceptible to weather conditions, and inefficient, failing to meet the needs of large-scale production. This has spurred the continuous development of organic fertilizer drying equipment.

[0003] Organic fertilizer drying equipment typically uses natural gas, biomass combustion, or steam heat exchangers as heat sources to heat air and generate high-temperature hot air. Wet material enters a rotating drum through the feed inlet. Inside the drum are lifting plates or hoisting devices that continuously tumble and toss the material, ensuring even dispersion within the dryer. The hot air contacts the material in a co-current or counter-current manner, transferring heat to the material and causing moisture evaporation. For example, in a rotary dryer, the material moves towards the other end of the dryer for drying as the drum rotates, aided by inclined lifting plates and the hot air.

[0004] However, the outlet position of the hot air in existing technologies is usually fixed. Although the organic fertilizer is turned and tossed by the drum, the limited coverage of the hot air will still result in the problem of incomplete drying of the fertilizer. Utility Model Content

[0005] This invention addresses the technical problem that, in existing technologies, the hot air outlet position is usually fixed, and although the organic fertilizer is turned over by the drum, the limited coverage of the hot air still results in incomplete drying of the fertilizer. Therefore, this invention provides an organic fertilizer drying device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an organic fertilizer drying device, comprising: a drying drum, the drying drum being inclined and rotatably connected to a frame, the drying drum being connected to a rotating power source, a screw feeder being rotatably connected to the center of the higher end side wall of the drying drum, the screw feeder being connected to the frame, bearing supports being connected to the inner walls of both ends of the drying drum respectively, a space being left between the bearing support on the higher side of the drying drum and the inner wall of the end of the drying drum, a hollow shaft being rotatably connected inside the two bearing supports, the hollow shaft being connected to the exhaust end of a hot air blower through a rotating sealing joint, the hollow shaft being connected to the power source through a transmission mechanism, multiple gas nozzles being evenly distributed around the circumference of the hollow shaft inside the drying drum, and spreading lining plates being evenly distributed around the circumference of the drying drum.

[0007] Preferably, the hollow shaft extends into the space between the bearing bracket on the higher side of the drying drum and the inner wall of the end of the drying drum. The hollow shaft in this space is solid, and levers are evenly distributed around the circumference of the hollow shaft in this space.

[0008] Preferably, there is a space between the lower end of the spreading liner and the lower end of the drying drum, and no gas nozzles are installed on the hollow shaft in this space.

[0009] Preferably, an input gear is connected to the outside of the drying drum, and the input gear meshes with the output gear of the power source.

[0010] Compared with the prior art, the beneficial effects of this utility model are: The drying drum drives the spreading liner to rotate and turn the fertilizer. Hot air is injected through the rotating hollow shaft and discharged in a 360° direction through the gas nozzle. The hot air blows the fertilizer in the air without dead angles, drying the fertilizer. The drying effect is very good.

[0011] After the fertilizer is injected, the hollow shaft drives the lever to rotate, breaking up the fertilizer. When the broken fertilizer is turned over, it is more dispersed and directly exposed to hot air, improving the drying efficiency. Attached Figure Description
