Description

Technical Field

[0001] The utility model relates to the technical field of fermentation tanks, and specifically relates to an organic sludge and livestock manure drying and fermentation device. Background Technique

[0002] Fermentation refers to the process by which people utilize the life activities of microorganisms under aerobic or anaerobic conditions to prepare the microorganisms themselves, or directly obtain metabolites or secondary metabolites. Fermentation is sometimes also written as "酦酵", and its definition varies depending on the usage scenario. Generally speaking, fermentation mostly refers to a certain decomposition process of organisms for organic matter. Fermentation is a biochemical reaction that humans came into contact with earlier. Nowadays, it is widely used in the food industry, biological and chemical industries. It is also a basic process of bioengineering, that is, fermentation engineering. The research on its mechanism and process control continues.

[0003] The existing patent is an efficient aerobic organic matter fermentation tank (CN207726990U), and the technical field it belongs to is the biological decomposition treatment and resource utilization of organic waste such as livestock manure, kitchen waste, domestic waste, and sludge. The problems to be solved are as follows: to provide an efficient aerobic organic matter fermentation tank, first, the longitudinal rotating main shaft in the center of the fermentation chamber of the fermentation tank is set into two sections, the upper and lower sections of the main shaft rotate in opposite directions, second, the upper and lower sections of the main shaft are connected by thrust bearings and ensured to be coaxial, so that the two groups of stirring paddles arranged on the upper half of the main shaft and the three groups of stirring paddles arranged on the lower half of the main shaft rotate in opposite directions, and the materials in the fermentation chamber are stirred in a reciprocal manner, so that the materials can be more fully aerated, fermented, decomposed, and dehumidified, shortening the fermentation time of the materials in the tank to 50 - 60 hours, and increasing the processing capacity of the fermentation tank by more than 20%.

[0004] After ventilation and oxygen supply in the above patent, the combination of the materials and oxygen is not very sufficient. Further improvements have been made to the above patent, and the structure related to ventilation and oxygen supply has been improved, making the materials and oxygen fully combined and shortening the fermentation time. Therefore, we propose an organic sludge and livestock manure drying and fermentation device to solve the above problems. Content of the Utility Model

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a device for drying and fermenting organic sludge and livestock and poultry manure, which has the following beneficial effects:

[0017] This invention utilizes the opposite rotation directions of the upper and lower rotating shafts, resulting in reversible mixing of the material. This avoids the clumping that easily occurs when mixing in the same direction, leading to better material dispersion and improved permeability. This allows for more thorough oxygen integration. The device also assists in heating the gas during oxygen delivery, enhancing both fermentation and drying effects. Simultaneously, the vents on the lower stirring rod deliver oxygen to the material's interior during mixing, ensuring more complete oxygen-material integration and shortening fermentation time. This fermentation device provides more efficient aerobic fermentation and decomposition of the material, reducing its residence time in the tank and significantly improving the fermenter's processing capacity.

[0022] 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.

[0023] Example

[0024] like Figure 1-3As shown in the figure, an embodiment of the present invention provides an organic sludge and livestock manure drying and fermentation device, comprising a fermentation tank 1, a conveyor 2, and a mixer 3. The device is characterized in that: a servo motor 5 is fixedly installed on the top of the fermentation tank 1; an upper rotating shaft 6 is fixedly connected to the output end of the servo motor 5; an upper stirring rod 7 for stirring is fixedly connected to the surface of the upper rotating shaft 6; an upper stirring blade 8 is welded to the surface of the upper stirring rod 7; a cylinder 9 is rotatably connected to the bottom of the fermentation tank 1 via a frame; a drive plate 10 is rotatably connected to the output end of the cylinder 9; a lower rotating shaft 11 is fixedly connected to the center of the drive plate 10 through a through-hole; and a lower stirring blade 8 for stirring is fixedly connected to the surface of the lower rotating shaft 11. The mixing rod, lower rotating shaft 11, and lower stirring rod are hollow structures. The surface of the lower stirring rod has an air vent 17. The bottom of the upper rotating shaft 6 is rotatably connected to the lower rotating shaft 11. An upper high-pressure vortex pump 21 and a lower high-pressure vortex pump 13 are respectively installed at the top and bottom of the fermentation tank 1. The output end of the upper high-pressure vortex pump 21 passes through the top of the fermentation tank 1. A transfer box 14 is installed at the output end of the lower high-pressure vortex pump 13. Several heating wires 15 are installed at the horizontal midline of the inner wall of the transfer box 14. A flexible hose 20 is fixedly connected to the air vent at the top of the transfer box 14. The end of the flexible hose 20 communicates with the bottom of the lower rotating shaft 11. A device for adjusting oxygen supply is installed on one side of the inner wall of the fermentation tank 1. The fermenter 1 includes an oxygen concentration sensor 18 and a temperature sensor 19 for adjusting auxiliary heating. A discharge port 16 for discharging material is located on one side of the bottom of the fermenter 1. When the fermenter 1 is working, the computer control system issues a command to transport the processed and mixed organic waste material to the fermenter 1 via a belt conveyor. The material entering the fermenter is stirred by the upper rotating shaft 6 and the lower rotating shaft 11 rotating in opposite directions. This reversible stirring prevents the material from clumping together, resulting in better material dispersion and increased permeability, allowing for better combination with oxygen. The fermenter 1 also supplies oxygen to the tank via upper and lower high-pressure vortex pumps 13. The oxygen concentration sensor 18 monitors the oxygen level and adjusts the oxygen supply through the upper and lower high-pressure vortex pumps 13. The temperature sensor 19 monitors the temperature inside the fermenter 1 and adjusts the temperature inside the fermenter 1 through the heating wire 15. The lower high-pressure vortex pump 13 at the bottom discharges oxygen through the lower rotating shaft 11 and the air outlet 17 on the lower stirring blade. By supplying oxygen, the gas can be heated, which can improve the fermentation and drying effect of the material. At the same time, the vent on the lower stirring rod can supply oxygen to the inside of the material during mixing, so that the oxygen combines more thoroughly with the material and shortens the fermentation time. The material processed by the above procedure is discharged from the discharge port 16 for collection.

[0025] like Figure 1 As shown, in some embodiments, the top of the fermenter 1 is connected to a deodorizing device 4 for exhausting gas via a gas supply pipe.

[0026] like Figure 1As shown, in some embodiments, the deodorization device 4 is one of an exhaust fan, a deodorizing fan, and a ventilation fan. The deodorization device can discharge moisture and odors from the fermentation tank 1 and collect and treat them.

[0027] like Figure 1 As shown, in some embodiments, the upper rotating shaft 6 and the lower rotating shaft 11 are coaxially installed, and the connection is fixed by the thrust bearing seat 12 and the thrust bearing, and can rotate in opposite directions, so that the material is subjected to mutual reversible mixing, avoiding the phenomenon of clumping and agglomeration when mixing in the same direction.

[0028] like Figure 1 and 2 As shown, in some embodiments, the arc swept by the rotational connection between the output end of the cylinder 9 and the drive plate 10 is a quarter circle, and the rotation arc of the lower rotating shaft 11 is 90°. This can satisfy the mixing of materials without hindering the connection between the hose 20 and the lower rotating shaft 11.

[0029] like Figure 1 As shown, in some embodiments, the mixer 3 transports the mixed materials into the fermentation tank 1 via the conveyor 2, saving on labor costs.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
