Description

Technical Field

[0001] This utility model relates to the technical field of equipment for organic fertilizer production, specifically to a lifting device for a homogenizing tank agitator in organic fertilizer production. Background Technology

[0002] Submersible mixers play a crucial role as core equipment in the organic fertilizer production process. They are primarily used in homogenization tanks to thoroughly stir and mix organic fertilizer raw materials, ensuring uniform contact and fusion between organic matter, microorganisms, and trace elements. Through efficient stirring, submersible mixers effectively improve the nutrient balance of fertilizers, thereby significantly enhancing fertilizer efficacy and quality. However, in practical applications, traditional submersible mixer modules are scattered and numerous, leading to a complex and cumbersome installation process. This not only consumes a significant amount of time and manpower but is also prone to malfunctions due to improper operation, severely impacting production efficiency.

[0003] Furthermore, existing mixer lifting devices suffer from an inadequate and uncompacted structural design, with complex connections between components. In the event of a malfunction, maintenance personnel must spend considerable time disassembling and troubleshooting, increasing equipment downtime and further impacting production continuity and stability. Simultaneously, the complex structure makes routine maintenance difficult, hindering the timely detection of potential problems and potentially shortening the equipment's lifespan. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and to provide a lifting device for a homogenizing tank in organic fertilizer production, which solves the technical problems of complex installation and time-consuming and labor-intensive maintenance in the field of lifting devices for agitators in organic fertilizer production.

[0005] To achieve the above-mentioned technical objectives, the present invention provides a lifting device for a homogenizing tank agitator in organic fertilizer production, comprising: The system comprises a fixed support, a circumferential adjustment mechanism, and a lifting adjustment mechanism.

Rollers are provided at both the upper and lower ends of the lifting slider. The outer walls of multiple rollers abut against the lifting rail. A traction bracket is hinged to the upper end of the lifting slider. The lifting plate assembly is driven by the traction bracket via a rope. The circumferential adjustment mechanism is provided on the upper part of the lifting rail. The circumferential adjustment mechanism includes a rotating disk fixedly connected to the upper end of the lifting rail. Multiple first positioning holes are formed in the circumferential array of the rotating disk. The fixed support is placed at the edge of the homogenizing tank.

[0011] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0012] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 This embodiment provides a lifting device for a homogenizing tank agitator used in organic fertilizer production, including: a fixed support 1, a circumferential adjustment mechanism 2, and a lifting adjustment mechanism 3.

[0013] Furthermore, the lifting adjustment mechanism 3 includes a lifting rail 31, a lifting slider 32, and a lifting plate assembly 33. The lifting slider 32 is sleeved on and slidably connected to the lifting rail 31. Rollers 321 are provided at both the upper and lower ends of the lifting slider 32, and the outer walls of the plurality of rollers 321 abut against the lifting rail 31. A traction bracket 34 is hinged to the upper end of the lifting slider 32, and the lifting plate assembly 33 is drivenly connected to the traction bracket 34 through a rope.

[0014] Furthermore, the side of the lifting slider 32 facing the center of the homogenizing tank 4 is fixedly connected to the fixed end of the agitator 5.

[0015] Furthermore, the roller 321 serves to provide support and reduce friction. When it is necessary to adjust the vertical position of the stirrer 5, an upward pulling force is applied to the lifting slider 32, causing the lifting slider 32 to move upward under the action of the roller 321; when it is necessary to lower the position of the stirrer 5, the pulling force on the lifting slider 32 is reduced, causing the stirrer 5 to move downward using its own gravity.

[0016] Furthermore, the upper part of the lifting track 31 is provided with the circumferential adjustment mechanism 2. The circumferential adjustment mechanism 2 includes a rotating disk 21 fixedly connected to the upper end of the lifting track 31. The rotating disk 21 has a plurality of first positioning holes 21A arranged in a circumferential array.

[0017] Furthermore, a fixed base 11 is fixedly connected to the top of the fixed bracket 1. The fixed base 11 has a track mounting hole 11A. The upper end of the lifting track 31 passes through the track mounting hole 11A. The rotating disk 21 is placed on the upper end of the fixed base 11. The fixed base 11 has a second positioning hole 11B corresponding to the first positioning hole 21A of the rotating disk 21.

[0018] Furthermore, the rotating disk 21 rotates circumferentially relative to the fixed base 11. Since the rotating disk 21 is fixedly connected to the lifting rail 31, when the rotating disk 21 is rotated, the stirrer 5 connected to the lifting rail 31 also rotates circumferentially, thereby adjusting the orientation of the stirrer 5. When the orientation of the stirrer 5 is adjusted, a set of first positioning holes 21A and second positioning holes 11B will always be aligned. Pins are inserted into the aligned first positioning holes 21A and second positioning holes 11B to restrict the rotation of the rotating disk 21, thereby enabling the stirrer 5 to rotate circumferentially and ensuring the stability of the stirrer 5 in subsequent operation.

[0019] Furthermore, the fixed bracket 1 is placed at the edge of the homogenizing tank 4, that is, the agitator 5 is set at the edge of the homogenizing tank 4. In the organic fertilizer production process, the design of placing the agitator 5 at the inner edge of the homogenizing tank 4 rather than in the middle is mainly based on the comprehensive consideration of the following process requirements and fluid mechanics principles: 1. Reduce dead zones and improve mixing efficiency: Organic fertilizer raw materials (such as livestock and poultry manure, straw, etc.) have high viscosity and uneven particle size. If the agitator is located in the center of the tank, it is easy to form a symmetrical vortex around the center axis during rotation, causing the material near the tank wall to accumulate due to insufficient centrifugal force, forming a dead zone. Setting the agitator at the edge can generate stronger shear force and circulation through rotating blades close to the tank wall, pushing the material to move along the tank wall and forming a composite flow in the horizontal and vertical directions, achieving more uniform mixing.

[0020] 2. Optimize mechanical structure and power distribution: The edge layout can shorten the length of the stirring shaft, reduce mechanical vibration and bearing load caused by the cantilever effect of the long shaft, extend the service life of the equipment, and avoid mechanical failures caused by material resistance when installed in the center position.

[0021] 3. Adapting to the temperature control and ventilation requirements of fermentation processes: During fermentation, stirring is necessary to promote contact between materials and microorganisms and oxygen diffusion. The turbulence generated by the stirrer at the edge can accelerate gas exchange within the tank, achieving more efficient oxygen supply and meeting the requirements of aerobic fermentation processes. The frictional heat generated during stirring is more easily conducted to the external heat dissipation system through the tank wall, preventing excessively high local temperatures (above 70°C) in the central area due to heat accumulation, which would inhibit microbial activity.

[0022] 4. Facilitates material circulation and integration with subsequent processes: The circulation created by edge stirring can lift the sediment at the bottom, thoroughly mixing it with the surface liquid and preventing stratification. When combined with the discharge port downstream of the homogenizing tank, edge stirring can directly propel the mixed material into the conveyor belt or fermentation tank, reducing energy loss in intermediate transition stages.

[0023] In summary, the design of placing the agitator 5 at the edge integrates material characteristics, equipment mechanical performance, and fermentation process requirements. It achieves efficient mixing through fluid dynamics optimization while also considering equipment stability and energy economy. In actual production, parameters such as the agitator blade angle and rotation speed need to be adjusted according to the type of raw materials and the tank size.

The first rotating body 333 and the second rotating body 334 are drivenly connected.

[0026] Preferably, the first rotating body 333 is a gear, and the second rotating body 334 is an I-beam wheel. The I-beam wheel is existing technology and is mainly used for the storage and fixing of wire ropes. Its shape is "I", hence the name.

[0027] Furthermore, the second rotating body 334 is provided with gear teeth on its circumferential side, which meshes and drives the first rotating body 333. The first rotating body 333 and the second rotating body 334 are connected by gear teeth meshing.

[0028] Furthermore, one side of the first rotating body 333 is welded and fixed to one end of the rotating handle 335. A bearing is provided on one side of the lifting plate bracket 331. The end of the rotating handle 335 that is fixedly connected to the first rotating body 333 is rotatably connected to the bearing. When the rotating handle 335 is rotated, the first rotating body 333 is driven to rotate. The second rotating body 334 is rotatably connected to the rotating plate bracket 331 through a rotating shaft and bearings. That is, the rotating shaft is fixedly connected to the second rotating body 334, and bearings are provided on both sides of the rotating plate bracket 331. The rotating shaft is rotatably connected to the bearings.

[0029] Furthermore, a rotating handle 335 is fixedly connected to one side of the first rotating body 333, and a limit hole 331A is opened on the side plate of the lifting plate bracket 331 that is rotatably connected to the first rotating body 333, and a limit post is inserted into the limit hole 331.

[0030] Furthermore, the second rotating body 334 is wound with the rope, which is placed in the limiting groove 332A of the pulley 332, and the other end of the rope is fixedly connected to the upper end of the traction bracket 34.

[0031] Furthermore, the cross-section of the fixing bracket 1 is triangular to improve its strength and stability. The bottom end of the fixing bracket 1 is fixedly connected to the upper end of the cover plate 6 of the homogenizing tank 4.
