Description

Technical Field

[0001] The utility model belongs to the technical field of biological organic fertilizer production, and particularly relates to a drying device for biological organic fertilizer. Background Technique

[0002] Biological organic fertilizer generally refers to using livestock and poultry manure or crop straw as the main raw material, using biochemical processes and microbial technologies to completely kill harmful substances such as pathogenic bacteria and parasite eggs contained in the raw materials and eliminate odors, and then inoculating microbial compound bacterial agents to decompose the organic matter in the raw materials, thus forming biological organic fertilizer. Compared with farmyard manure, biological organic fertilizer has a light odor after deodorization and is almost odorless; and it is evenly processed and convenient to apply.

[0003] At present, the industrial production of biological organic fertilizer mainly goes through steps such as fermentation, secondary fermentation, screening and processing, granulation, drying, cooling, and packaging. The fermented biological organic fertilizer undergoes screening and processing and then granulation. The water content of the just granulated biological organic fertilizer particles is relatively large, and the water needs to be dried to less than 20% of the biological organic fertilizer standard. In the existing technology, biological organic fertilizer drying equipment has columnar, drum-type, and rotary structures, and the columnar drying device is used more. However, in the actual use process, the stirring device in the columnar drying device is set simply and cannot achieve the effect of sufficient stirring, resulting in caking of biological organic fertilizer during drying and low drying uniformity of biological organic fertilizer. Therefore, it is necessary to design a drying device for biological organic fertilizer that can avoid caking. Content of the Utility Model

[0004] Aiming at the above technical problems, the utility model provides a drying device for biological organic fertilizer that can avoid caking, so as to solve the problem that the stirring device in the drying device is set simply and cannot achieve the effect of sufficient stirring, resulting in caking of biological organic fertilizer during drying and low drying uniformity of biological organic fertilizer.

[0005] To solve the above technical problems, the technical solution of the present utility model is as follows: A biological organic fertilizer drying device includes a drying box. A feeding port is provided at the top of the drying box, a stirring mechanism is arranged inside, and a discharging port is provided at the bottom. A hot air inlet is fixedly connected to the lower side of the drying box, and a hot air outlet is fixedly connected to the upper side. The stirring mechanism includes a first stirring shaft, a second stirring shaft arranged in parallel in the horizontal direction, and a third stirring shaft located below the first stirring shaft and the second stirring shaft. A number of stirring teeth are fixedly connected to the first stirring shaft, the second stirring shaft, and the third stirring shaft at intervals. Both ends of the first stirring shaft, the second stirring shaft, and the third stirring shaft are rotatably connected to the side wall of the drying box. One end of the first stirring shaft, the second stirring shaft, and the third stirring shaft extends outside the drying box and is respectively fixedly connected to a first gear, a second gear, and a third gear. A motor is fixedly connected to the outside of the drying box, and the output end of the motor is fixedly connected to a driving gear. The driving gear, the first gear, and the second gear are all meshed with the third gear.

[0006] Further, a screw conveyor is fixedly connected to the lower end of the discharging port.

[0007] Further, a material distributing plate is arranged below the feeding port. The material distributing plate is in an inverted V shape and is fixedly connected to the inner wall of the drying box.

[0008] Further, a mounting plate is fixedly connected to the outside of the drying box, and the motor is fixedly connected to the upper part of the mounting plate.

[0009] Further, four support legs are fixedly connected to the bottom of the drying box.

[0010] The present utility model has the following advantages compared with the prior art:

[0011] 1. By arranging the first stirring shaft, the second stirring shaft, and the third stirring shaft in the drying box, and the first stirring shaft, the second stirring shaft, and the third stirring shaft are distributed in an inverted triangle in the drying box, and stirring teeth are installed at intervals on the three stirring shafts, the biological organic fertilizer to be dried can be stirred more fully. The rotation direction of the third stirring shaft is opposite to that of the first stirring shaft and the second stirring shaft. The third stirring shaft can continuously turn up the biological organic fertilizer at the bottom of the drying barrel, and cooperate with the reversely rotating first stirring shaft and second stirring shaft to fully stir the biological organic fertilizer, avoiding its caking and improving the drying uniformity of the biological organic fertilizer.

[0012] 2. By installing a material distributing plate below the feeding port, the present utility model can prevent the added biological organic fertilizer from accumulating and causing blockage of the device, and improve the stability of the equipment operation. BRIEF DESCRIPTION OF THE DRAWINGS
