An organic fertilizer fermentation device

Abstract

This utility model relates to the field of organic fertilizer processing technology, specifically to an organic fertilizer fermentation device. To address the technical problem in existing trough-type fermentation devices where the turning mechanism and fermentation trough are separate, resulting in dead corners that cannot be turned and difficult to handle after caking, this invention provides two horizontally positioned rotating shafts in each fermentation chamber. These shafts are rotatably connected to the side wall of the fermentation trough, with parallel axes on the same vertical plane. The lower shaft is concentrically positioned with the bottom surface of the fermentation chamber. Each shaft is equipped with a spiral blade, the diameter of which is the same as the width of the fermentation chamber. The two shafts in the same fermentation chamber convey fertilizer in opposite directions. When turning the fertilizer, the two spiral blades operate synchronously, breaking up caking and allowing the upper and lower layers of fertilizer to flow and mix in a circular motion. Each layer of organic fertilizer is in full contact with air, and there are no dead corners at the bottom or edges of traditional fermentation troughs, resulting in excellent turning performance.

Description

Technical Field

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

[0002] With the scaling up of the livestock industry and the surge in the production of organic waste in urban and rural areas, the limitations of traditional treatment methods have become increasingly apparent. On the one hand, large amounts of untreated organic waste can easily cause soil and water pollution, violating ecological and environmental protection requirements. On the other hand, the long-term excessive use of chemical fertilizers has led to soil compaction and soil fertility decline, prompting a continuous increase in market demand for high-quality organic fertilizers. Against this backdrop, mechanized and intelligent organic fertilizer fermentation devices have emerged. Their core objective is to shorten the fermentation cycle and improve the quality of organic fertilizers through artificial control of the fermentation environment, while simultaneously achieving the reduction, harmlessness, and resource utilization of organic waste.

[0003] Currently, fermentation equipment on the market has evolved from early simple turning devices to complete systems encompassing various types such as trough-type, windrow-type, and tank-type. Among them, trough-type fermentation equipment has become the mainstream choice for small and medium-sized organic fertilizer plants and large-scale farms due to its advantages such as controllable floor space, easy adjustment of fermentation parameters, and suitability for large-scale production. Trough-type fermentation equipment focuses on "artificially creating an aerobic fermentation environment," using a trough to carry materials and in conjunction with components such as turning mechanisms to achieve rapid decomposition of organic waste.

[0004] The existing trough fermentation device has a separate turning mechanism from the fermentation trough, which results in dead corners inside the fermentation trough that cannot be turned over, making it difficult to deal with the hardened material. Utility Model Content

[0005] This invention addresses the technical problem in existing trough-type fermentation devices where the turning mechanism and fermentation trough are separate, resulting in dead corners within the fermentation trough that cannot be turned over, and where the resulting hardened material is difficult to handle. Therefore, this invention provides an organic fertilizer fermentation device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an organic fertilizer fermentation device, comprising: a fermentation tank, which is divided into multiple fermentation chambers, each fermentation chamber having a semi-circular bottom cross-sectional curve, and each fermentation chamber having two horizontally arranged rotating shafts rotatably connected to the side wall of the fermentation tank. The axes of the two rotating shafts are parallel and located in the same vertical plane, with the lower rotating shaft concentrically arranged with the bottom surface of the fermentation chamber. Each rotating shaft is connected to a spiral blade, the diameter of which is the same as the width of the fermentation chamber, and the two rotating shafts in the same fermentation chamber have opposite conveying directions.

[0007] Preferably, each shaft end is connected to a corresponding gear, two gears in the same fermentation chamber mesh with each other, adjacent upper shafts are connected by belt drive, and adjacent lower shafts are connected by belt drive.

[0008] Preferably, the fermentation tank at the end of the fermentation chamber is provided with a side wall on one side, and the two sides of the fermentation tank without a side wall are connected to vertical slide rails. A discharge gate is slidably connected in the vertical slide rails, and the discharge gate slides along the vertical slide rails by a hydraulic cylinder.

[0009] Preferably, the spiral blades on the rotating shaft are disconnected, and a bearing bracket is rotatably connected to the rotating shaft at the disconnection point. Two bearing brackets in the same fermentation chamber are connected to the inner wall of the fermentation chamber by a fixed bracket, which is a cylindrical rod.

[0010] Compared with the prior art, the beneficial effects of this utility model are: By dividing the fermentation tank into multiple fermentation chambers, each fermentation chamber is equipped with two spiral blades with opposite conveying directions. When the fertilizer is turned over, the two spiral blades operate synchronously, breaking up the compaction and making the upper and lower layers of fertilizer flow and mix in a ring. Each layer of organic fertilizer is in full contact with the air, and there are no dead corners at the bottom and edges of the traditional fermentation tank, resulting in a very good turning effect.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] The rotary connection described in this device refers to the axial fixation of the bearing by mounting the bearing on the shaft, with a spring retaining ring groove provided on the shaft or shaft hole, and the rotation achieved by locking the elastic retaining ring in the retaining ring groove; the hinge connection refers to the connection method that allows movement through connecting parts such as hinges, pins, and short shafts.

[0015] The present invention will now be described in detail with reference to the accompanying drawings.

[0016] The following is in conjunction with the appendix Figure 1-3 This embodiment describes an organic fertilizer fermentation device, comprising: a fermentation tank 1, which is divided into multiple fermentation chambers 2. The bottom cross-sectional curve of each fermentation chamber 2 is semi-circular. Each fermentation chamber 2 is provided with two horizontally arranged rotating shafts 3, which are rotatably connected to the side wall of the fermentation tank 1. The axes of the two rotating shafts 3 are parallel and located in the same vertical plane. The lower rotating shaft 3 is concentric with the bottom surface of the fermentation chamber 2. Each rotating shaft 3 is connected with a spiral blade 5. The diameter of the spiral blade 5 is the same as the width of the fermentation chamber 2. The two rotating shafts 3 in the same fermentation chamber 2 have opposite conveying directions.

[0017] During feeding, the organic fertilizer is evenly distributed in each fermentation chamber 2. The power of the rotating shaft 3 is turned on, and the rotating shaft 3 drives the spiral blades 5 to rotate. The fertilizer falls into the gaps of the spiral blades 5, and the volume of the fermentation chamber 2 is not significantly reduced due to the setting of the spiral blades 5. During stirring, the two spiral blades 5 operate synchronously to break up the clumps. Since the two rotating shafts 3 in the same fermentation chamber 2 convey in opposite directions, the upper and lower layers of fertilizer flow and mix in a ring. Each layer of organic fertilizer is in full contact with the air, and there are no dead corners at the bottom and corners of the traditional fermentation tank. The fertilizer in the dead corners outside the outer diameter of the spiral blades 5 on both sides of the fermentation chamber 2 will also be rubbed and flowed by the organic fertilizer pushed by the spiral blades, and the turning effect is very good.

[0018] Each shaft 3 is connected to a corresponding gear 6 at its end. The two gears 6 in the same fermentation chamber 2 mesh with each other. The upper adjacent shafts 3 are connected by a belt drive 7, and the lower adjacent shafts 3 are connected by a belt drive 7.

[0019] The power drives one rotating shaft 3 to rotate. The two rotating shafts 3 in the same fermentation chamber 2 rotate in opposite directions under the action of gears. The spiral blades 5 on the two rotating shafts 3 have the same spiral direction, so that the two rotating shafts 3 in the same fermentation chamber 2 convey in opposite directions. The rotating shafts 3 located at the upper and lower parts are connected by corresponding belt drives 7. The whole stirring operation can be driven by only one power.

[0020] The fermentation tank 1 at the end of the fermentation chamber 2 is provided with a side wall on one side. The two sides of the fermentation tank 1 without a side wall are connected to vertical slide rails 8. A discharge gate 9 is slidably connected in the vertical slide rails 8. The discharge gate 9 slides along the vertical slide rails 8 through a hydraulic cylinder 10.

[0021] During discharge, the hydraulic cylinder 10 is extended, and the fixed end of the hydraulic cylinder 10 is fixed to the ground or the frame. The extension end of the hydraulic cylinder 10 drives the discharge gate 9 to slide along the vertical slide rail 8, so that the end of the fermentation chamber 2 is connected to the outside, interrupting the circular flow of fertilizer, and allowing the fertilizer to be discharged through this point, thus completing the discharge.

[0022] The spiral blade 5 on the rotating shaft 3 is disconnected, and a bearing bracket 11 is rotatably connected to the rotating shaft 3 at the disconnection point. The two bearing brackets 11 in the same fermentation chamber 2 are connected to the inner wall of the fermentation chamber 2 through a fixed bracket 12, which is a cylindrical rod.

[0023] The bearing bracket 11 and the fixed bracket 12 cooperate to provide another support for the rotating shaft 3, so as to avoid deformation of the rotating shaft 3. The disconnection of the spiral blade 5 does not affect the conveying function, and the cylindrical rod of the fixed bracket 12 will not obstruct the flow of fertilizer.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
