Description

Technical Field

[0001] This utility model relates to the field of horizontal fermentation tank technology, specifically a biological organic fertilizer fermentation device. Background Technology

[0002] Organic fertilizer fermentation is the process of transforming organic materials into stable, harmless, and nutrient-rich organic fertilizer through the action of microorganisms. Currently, there is a type of horizontal fermentation tank for organic fertilizer fermentation on the market, and its working principle is as follows:

[0003] After crushing organic waste such as livestock and poultry manure and kitchen waste, it is put into the tank according to a certain ratio of carbon to nitrogen and moisture. Inoculum is added to start fermentation. The stirring system drives the material to turn over, so that the material can fully contact the air. Oxygen is introduced into the bottom to promote the metabolism of aerobic microorganisms. At the same time, the heating system maintains a high temperature to kill pathogens and insect eggs and promote the decomposition of organic matter. After a period of time, the material is decomposed into stable organic fertilizer, which can be used directly for soil improvement or further processed into granular fertilizer.

[0004] Compared to traditional vertical tanks and cylindrical tanks, horizontal fermenters have advantages such as smaller footprint and shorter fermentation time. However, in actual use, dead zones are prone to occur in the middle area between the two spiral stirring blades of a horizontal fermenter, leading to uneven mixing and material clumping, which is not conducive to the full fermentation of organic fertilizer. Based on this, a biological organic fertilizer fermentation device is provided. Utility Model Content

[0031] The mixing and stirring assembly 2 includes a stirring unit, an anti-caking unit, and a transmission unit;

[0032] The stirring unit is used to stir the materials inside the tank 101;

[0033] The transmission unit is used to transmit the rotational power of the stirring unit to the anti-caking unit, so that the anti-caking unit rotates while running in a circle, thereby further stirring the areas that the stirring unit failed to reach.

[0034] The stirring unit includes a geared motor 201, a central shaft 202, a connecting rod 203, and a spiral stirring blade 204;

[0035] The geared motor 201 is installed on one end of the outside of the tank 101. The central shaft 202 is distributed inside the tank 101 and its two ends are rotatably connected to the tank 101. One end of the central shaft 202 passes through the tank 101 and is connected to the output end of the geared motor 201.

[0036] The central shaft 202 is connected to two spiral stirring blades 204 with opposite spiral directions via a connecting rod 203. The outer diameters of the two spiral stirring blades 204 increase sequentially, and the outer diameter of the larger diameter spiral stirring blade 204 matches the diameter of the bottom of the inner wall of the tank 101.

[0037] The anti-caking unit includes a turntable 205 and a spiral stirring shaft 206;

[0038] Turntables 205 are symmetrically fixed on the outer sides of both ends of the central shaft 202 and distributed on the inner side of the tank 101. Spiral stirring shaft 206 passes through the middle area of ​​two spiral stirring blades 204 and is rotatably connected to the two turntables 205.

[0039] The spiral stirring shaft 206 rotates and moves in a circular motion to agitate the material in the area between the two spiral stirring blades 204.

[0040] The transmission unit includes a gear 207, a fixed ring seat 208, and a gear ring 209;

[0041] The fixed ring seat 208 is symmetrically fixed at both ends of the inner wall of the tank body 101, and the turntable 205 is rotatably connected to the inner side of the fixed ring seat 208;

[0042] Both ends of the spiral stirring shaft 206 pass through the turntable 205 to the inner side of the fixed ring seat 208 and are fixedly connected to the gear 207;

[0043] The toothed ring 209 is fixed to the inner wall end face of the fixed ring seat 208 and sleeved on the outside of the gear 207. The toothed ring 209 meshes with the gear 207, and the gear 207 and the toothed ring 209 cooperate to realize the rotation of the spiral stirring shaft 206.

[0044] In this embodiment, it should be noted that: the tank body 101 is equipped with an outlet and an inlet that communicate with the heating inner chamber 102 to realize the circulation of the heating medium. The discharge port 104 is equipped with a valve to control the material discharge operation. This part of the structure is the conventional structure of the existing fermentation tank 1, and will not be drawn or expanded in detail here.

[0045] The operating principle of mixed fermentation of organic fertilizer raw materials is as follows:

[0046] The organic fertilizer raw materials to be fermented are poured into the tank 101 according to the set ratio. At the same time, the reduction motor 201 is started. The reduction motor 201 drives the central shaft 202 and the turntable 205 to rotate as a whole. The central shaft 202 drives the two spiral stirring blades 204 to rotate. The two spiral stirring blades 204 with opposite spiral directions can realize the reciprocating stirring and mixing of materials.

[0047] At the same time, the turntable 205 drives the spiral stirring shaft 206 and gear 207 to rotate circumferentially. The gear 207 rotates under the limiting action of the gear ring 209, which in turn realizes the rotation of the spiral stirring shaft 206. The circumferentially rotating and self-rotating spiral stirring shaft 206 can stir the material between the two spiral stirring blades 204 (it should be noted that spiral stirring blades are fixed on the outside of the spiral stirring shaft 206), thereby effectively avoiding insufficient mixing and clumping of materials, further improving the mixing efficiency of organic fertilizer raw materials, ensuring the uniformity of organic fertilizer mixing, and thus facilitating the full fermentation of organic fertilizer.

[0048] Please refer to this carefully. Figures 2-4 The spiral stirring shaft 206 is provided in two sets and each set has multiple sets. The two sets of spiral stirring shafts 206 are respectively distributed in the two turntables 205 and the area between the small diameter turntable 205 and the reduction motor 201. Each set of spiral stirring shafts 206 is evenly distributed in a ring.

[0049] Two gear rings 209 are provided, and the two gear rings 209 mesh with the gears 207 corresponding to the two sets of spiral stirring shafts 206 respectively.

[0050] In this embodiment, the efficient mixing and dispersing of materials can be achieved through the circumferential operation and rotation of the two sets of spiral stirring shafts 206, effectively preventing the material between the two spiral stirring blades 204 and the material between the small-diameter spiral stirring blades 204 and the central shaft 202 from clumping.
