Description

Technical Field

[0001] This utility model belongs to the field of organic fertilizer fermentation technology, specifically relating to an organic fertilizer wheel-type turning and aerobic post-fermentation tank. Background Technology

[0002] Organic fertilizer fermentation is the process by which microorganisms decompose organic matter and transform it into stable humus. The most common fermentation method is aerobic fermentation, which relies primarily on aerobic microorganisms such as bacteria, fungi, and actinomycetes to decompose organic matter (such as livestock manure, straw, and kitchen waste) under sufficient oxygen conditions, producing carbon dioxide, water, and heat, while simultaneously synthesizing humus. Organic fertilizer fermentation generally consists of four stages: the heating period, the high-temperature period, the cooling period, and the maturation period. Aerobic post-fermentation is a crucial stabilization and quality-improving stage in the composting process. After the main high-temperature decomposition stage, under continuous aerobic conditions, it utilizes mesophilic microbial communities (fungi, actinomycetes, etc.) to slowly and thoroughly decompose residual recalcitrant organic matter (especially lignocellulose), synthesizing stable humus, eliminating phytotoxicity and odor, and ultimately producing a highly stable, safe, mature, and humus-rich high-quality compost product.

[0003] The wheel-type turning and composting fermentation tank is the mainstream equipment for large-scale organic fertilizer production. It precisely supplies oxygen through an aeration system at the bottom of the tank, and the wheel-type turning and composting machine operates at a depth (1.5-3 meters), ensuring uniform mixing of materials, high oxygen permeability, and stable high-temperature fermentation (55-70℃), shortening the fermentation cycle to 7-15 days (compared to 30-60 days for traditional windrow fermentation). However, in practical use, it still suffers from drawbacks such as the aeration holes being easily clogged by materials and the turning rollers easily becoming entangled with straw. Therefore, there is an urgent need to design an aerobic post-fermentation tank for organic fertilizer using a wheel-type turning and composting system to solve these problems. Utility Model Content

[0006] The fermentation tank body has a slide rail on the top, a slider on the slide rail, a drive motor at one end of the slide rail, and a turning machine on the top of the fermentation tank body. The turning machine includes a horizontal plate fixed to the slider, a vertical plate fixed to both ends of the horizontal plate, a rotary motor fixed to one end of the horizontal plate, and a roller rotatably connected between the two vertical plates. The roller has blades and strip grooves.

[0007] The backflush mechanism includes an aeration pipe network, an air source box, and a control unit. The aeration pipe network is located at the bottom of the fermentation tank body and includes a main pipe, branch pipes, and a backflush pipe connected in sequence.

[0008] An anti-winding mechanism includes comb plates fixed to both sides of a strip groove, a second slide rail fixed to the bottom of the strip groove, a second slider slidably connected to the second slide rail, and a cutting tooth fixed to the second slider. One end of the second slide rail is provided with a second drive motor.

[0009] Furthermore, the gas source box is located on the outside of the fermentation tank body. The gas source box contains an air compressor unit and an air storage tank. The air outlet of the air compressor unit is sealed to the air inlet of the air storage tank. The air storage tank has two air outlets, which are connected to the air inlet of the main pipeline and the air outlet of the branch pipeline respectively through air pipes.

[0010] Furthermore, the control unit includes an air supply valve disposed at the air inlet end of the branch pipe, a backflush valve disposed at the air outlet end of the branch pipe, and a pressure sensor disposed inside the branch pipe.

[0011] Furthermore, both the output end of the rotary motor and one end of the roller are fixed with sprockets, and the rotary motor and the roller are connected by chain drive.

[0012] Furthermore, there are several branch pipes, all of which are arranged vertically and are equidistant from each other, and the outer surface of the top end of each branch pipe is provided with several aeration holes.

[0015] The technical effects and advantages of this utility model are as follows: This organic fertilizer wheel-type aerobic post-fermentation tank is advanced in design, compact in structure, and easy to use. By setting up a back-blowing mechanism, the gas storage tank blows air into the branch pipe through the back-blowing pipe. The high-pressure gas pulses in the reverse direction to impact the blockages in the aeration holes, which can effectively remove blockages such as manure residue, straw fragments, and mycelium clumps with a particle size greater than 0.3 mm. By setting up an anti-winding mechanism, the comb plate can separate the tangled grass, and the slider two drives the cutting teeth to move back and forth, which can cut the grass and prevent it from winding on the roller, making the turning machine run more smoothly.

[0023] This utility model provides, for example Figure 1-3 The organic fertilizer rotary turning aerobic post-fermentation tank shown includes:

[0024] The fermentation tank body 100 has a slide rail 101 on its top. A slider 102 is slidably connected to the slide rail 101. A drive motor 103 is provided at one end of the slide rail 101. The drive motor 103 drives the slider 102 to reciprocate along the slide rail 101. A turning machine 104 is provided at the top of the fermentation tank body 100. The turning machine 104 includes a horizontal plate 1041 fixed to the slider 102, a vertical plate 1042 vertically fixed to both ends of the horizontal plate 1041, a rotary motor 1043 fixed to one end of the horizontal plate 1041, and a roller 1044 rotatably connected between the two vertical plates 1042. The roller 1044 is provided with blades 1045 and strip grooves 1046.

[0025] The backflush mechanism 200 includes an aeration pipe network 201, an air source box 202, and a control unit 203. The aeration pipe network 201 is located at the bottom of the fermentation tank body 100. The aeration pipe network 201 includes a main pipe 2011, a branch pipe 2012, and a backflush pipe 2013 connected in sequence.

[0026] The anti-winding mechanism 300 includes a comb plate 301 fixed to both sides of the strip groove 1046, a slide rail 302 fixed to the bottom of the strip groove 1046, a slider 303 slidably connected to the slide rail 302, and a cutting tooth 304 fixed to the slider 303. One end of the slide rail 302 is provided with a drive motor 305.

[0027] For example, see Figure 2 As shown, the gas source box 202 is located on the outside of the fermentation tank body 100. The gas source box 202 is equipped with an air compressor unit 2021 and an air storage tank 2022. The air outlet of the air compressor unit 2021 is sealed to the air inlet of the air storage tank 2022. The air storage tank 2022 has two air outlets. The two air outlets are respectively connected to the air inlet of the main pipeline 2011 and the air outlet of the branch pipeline 2012 through air pipes.

[0028] In this technical solution, the air compressor unit 2021 produces compressed air and injects it into the air storage tank 2022. During normal aeration, the compressed air enters the branch pipe 2012 through the main pipe 2011 and provides forced ventilation and oxygen supply to the material pile. During backflushing and cleaning, the air storage tank 2022 inputs the stored high-pressure gas (0.5-0.8MPa) from the top of the branch pipe 2012.

[0029] For example, see Figure 2 As shown, the control unit 203 includes an air supply valve 2031 disposed at the air inlet end of the branch pipe 2012, a backflush valve 2032 disposed at the air outlet end of the branch pipe 2012, and a pressure sensor 2033 disposed inside the branch pipe 2012.

[0030] In this technical solution, the opening and closing of the air supply valve 2031 controls the air inlet end of the branch pipe 2012, and the opening and closing of the backflush valve 2032 controls the air outlet end of the branch pipe 2012. The pressure sensor 2033 is used to monitor the pipe pressure of the branch pipe 2012. When the pipe pressure is greater than 0.2MPa, it indicates that the aeration resistance has increased, triggering a blockage warning.

[0031] For example, see Figure 2 As shown, both the output end of the rotary motor 1043 and one end of the roller 1044 are fixed with sprockets, and the rotary motor 1043 and the roller 1044 are connected by a chain 1047.

[0032] In this technical solution, the rotary motor 1043 drives the roller 1044 to rotate via the chain 1047. The blades 1045 on the roller 1044 rotate together and turn over the material pile, which can make the material mix evenly, improve oxygen permeability, stabilize the high temperature fermentation stage (55-70℃), and shorten the fermentation cycle to 7-15 days.

[0033] For example, see Figure 2 As shown, there are several branch pipes 2012, all of which are arranged vertically and are equidistant. The outer surface of the top end of each branch pipe 2012 is provided with several aeration holes 2014.

[0034] In this technical solution, during aeration, compressed gas enters the branch pipe 2012 and supplies oxygen to the material pile through the aeration hole 2014. During backflushing, high-pressure gas (0.5-0.8MPa) rushes into the aeration hole 2014 in the opposite direction. The high-pressure airflow expands instantaneously, generating explosive force, which breaks up the organic particles adhering to the hole. The airflow passes through the narrow channel at high speed (flow velocity > 20m / s), forming shear force to peel off the blockage.

[0035] For example, see Figure 1As shown, the inner wall of the fermentation tank body 100 is provided with a heat insulation layer 105, and a touch screen display 106 and an alarm device 107 are provided on one side of the fermentation tank body 100.

[0036] In this technical solution, the insulation layer 105 is filled with insulation materials (polystyrene board, rock wool, glass wool, polyurethane foam, etc.), which can effectively maintain the high temperature period of fermentation of materials in the tank, which is conducive to improving the fermentation quality. The touch screen 106 is electrically connected to each electrical appliance, which can control the start and stop of each electrical appliance and display the operating status of each electrical appliance. When the pressure sensor 2033 detects that the pipeline pressure of the branch pipe 2012 is greater than 0.2MPa, an alarm is issued to remind the staff to perform backflushing self-cleaning operation.

[0037] For example, see Figure 1 As shown, a PLC controller 2034 is electrically connected to one side of the touch screen 106. The PLC controller 2034 is electrically connected to the drive motor 103, the rotary motor 1043, the alarm device 107, the air source box 202, the control unit 203, and the drive motor 305.

[0038] In this technical solution, control commands can be easily input and the operating status of each electrical appliance can be displayed on the touch screen 106. The control commands are transmitted to each electrical appliance via the PLC controller 2034 to control the start and stop of each electrical appliance.

[0039] Working principle: When using this organic fertilizer wheel-type aerobic fermentation tank, first place the material in the main body 100 of the fermentation tank, then start the drive motor 103 and the rotary motor 1043. The drive motor 103 drives the turner 104 to reciprocate along the slide rail 101, and the rotary motor 1043 drives the roller 1044 to rotate, so that the blades 1045 can turn and toss the material in the tank. At the same time, the air compressor unit 2021 is started to deliver compressed air to the branch pipe 2012 and force it into the material through the aeration holes 2014. When the aeration hole 2014 is blocked, the air supply valve 2031 is closed and the backflush valve 2032 is opened. The high-pressure gas in the air storage tank 2022 is pushed back into the aeration hole 2014, which can remove the blockage. When grass, straw, etc. are wrapped around the roller 1044, the drive motor 2 305 is started. The drive motor 2 305 drives the cutting tooth blade 304 to move back and forth along the slide rail 2 302. The grass, straw, etc. are cut by the cutting tooth blade 304 and fall off the roller 1044. Then they are mixed in the material by the turner 104 to achieve degradation. This organic fertilizer wheel-type aerobic fermentation tank is advanced in design, compact in structure, and easy to use. With the back-blowing mechanism 200, the air storage tank 2022 blows air into the branch pipe 2012 through the back-blowing pipe 2013. The high-pressure gas reverse pulse impacts the blockage in the aeration hole 2014, which can effectively remove blockages such as manure residue, straw fragments, and mycelium clumps with a particle size greater than 0.3 mm. With the anti-winding mechanism 300, the comb plate 301 can separate the tangled grass, and the slider 303 drives the cutting tooth blade 304 to move back and forth, which can cut the grass and prevent it from winding on the roller 1044, making the operation of the turner 104 smoother.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
