DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] As mentioned above, the prior art requires manual regular stirring or rotary stirring for the fermentation of organic fertilizers, and the control of the temperature and humidity of the organic fertilizers is not effective in promoting the fermentation.

[0022] In view of this, the present invention provides a ventilation and humidification device for organic fertilizer fermentation, which can realize the self-rotation of the driven gear 503 by the driven gear 503 rotating around the gear ring 501 with the teeth facing inward, and the stirring rod 504 connected to the lower side of the driven gear 503 rotates to stir the organic fertilizer inside the compost bucket 1. The stirring rod 504 is bent in the middle section to increase the stirring range, stir the organic fertilizer more evenly, and stir it more quickly. It is easy to adjust the organic fertilizer inside the compost bucket 1 through the external ventilation component 2 and the temperature and humidity adjustment mechanism 3. The preset temperature and humidity controlled inside the compost bucket 1 can make the organic fertilizer have a better fermentation effect.

[0023] Combine the following Figure 1 to Figure 14 The present invention is described in detail.

[0024] First embodiment: like Figure 1 to Figure 14 As shown, the present invention provides a ventilation and humidification device, in particular, a ventilation and humidification device for organic fertilizer fermentation. In this embodiment, the ventilation and humidification device includes a compost bucket 1, a ventilation component 2, a temperature and humidity adjustment mechanism 3, a discharging mechanism 4, a stirring component 5, a sealed barrel cover 6, a collection barrel 7 and a one-way valve mechanism 8. Among them, the compost bucket 1 with heat preservation and temperature and humidity measurement functions, a sealed barrel cover 6 is provided on the upper side of the outside of the compost bucket 1, a discharge port 402 is provided on the lower side of the outside of the sealed barrel cover 6, and a collection barrel 7 for collecting and holding the fertilizer fermented from the discharge port 402 is provided on the lower side of the outside of the compost bucket 1. As shown in FIG. Figure 3 As shown, the inner bottom of the compost bucket 1 has a surface with an inclined surface inclined toward the center, so that the fertilizers fermented inside the compost bucket 1 can be gathered toward the center. A ventilation component 2 is provided on one side of the outer sides of the compost bucket 1, and a temperature and humidity adjustment mechanism 3 is provided on the other side. The ventilation component 2 can introduce airflow into the interior of the compost bucket 1, introduce air or other gases into the organic fertilizers piled inside the compost bucket, and adjust the temperature and humidity inside the compost bucket 1. The temperature and humidity adjustment mechanism 3 can introduce water mist or water vapor into the interior of the compost bucket 1 and heat the introduced water mist or water vapor according to a preset value, and cooperate with the ventilation component 2 to adjust the temperature and humidity inside the compost bucket 1.

[0025] A stirring assembly 5 is provided on the lower inner side of the sealed barrel cover 6. The stirring assembly 5 stirs the organic fertilizer in the compost barrel 1 on the lower inner side of the sealed barrel cover 6. The stirring assembly 5 can stir the organic fertilizer in the compost barrel 1 when the organic fertilizer is mixed with the microbial flora, and can also stir the organic fertilizer during the fermentation process, so that the temperature and humidity of the organic fertilizer can be distributed more evenly. At the same time, when the ventilation assembly 2 and the temperature and humidity adjustment mechanism 3 are used to ventilate or adjust the temperature and humidity of the organic fertilizer in the compost barrel 1, the organic fertilizer in the compost barrel 1 can be more evenly exposed to the airflow or water vapor, thereby increasing the uniformity of adjusting the temperature and humidity of the organic fertilizer in the compost barrel 1. A discharging mechanism 4 is provided on the lower outer side of the compost barrel 1. The discharging mechanism 4 can filter the moisture inside the organic fertilizer pile, and then discharge the fertilizer fermented inside the compost barrel 1 through the discharging mechanism 4 after opening.

[0026] like Figure 1 to Figure 6 As shown, the ventilation assembly 2 includes a ventilation duct 201, a ventilation branch pipe 202, a connecting pipe 203, an air outlet pipe 204 and a pressure relief valve 205. Among them, a plurality of ventilation ducts 201 are evenly distributed on one side of the outside of the compost bucket 1, and the interior of the ventilation duct 201 and the interior of the compost bucket 1 are connected together. A ventilation branch pipe 202 is arranged on the side of the ventilation duct 201 away from the compost bucket 1, and the side of the ventilation branch pipe 202 close to the ventilation duct 201 is a branch pipe with the same number as the ventilation duct 201, and the side of the ventilation branch pipe 202 away from the ventilation duct 201 is a collection pipeline, and an L-shaped connecting pipe 203 is arranged on the side of the ventilation branch pipe 202 away from the ventilation duct 201, and the other end of the connecting pipe 203 connected to the ventilation branch pipe 202 is bent downward, and a fan is connected, and the filtered airflow is passed into the interior of the connecting pipe 203 through the fan. Airflow is introduced from the inside of the connecting pipe 203 to the inside of the branch pipe, and then the airflow sent by the fan is transported to the inside of the ventilation branch pipe 202 through the branch pipe. Since a one-way valve mechanism 8 is provided inside the ventilation duct 201, when the airflow flows from the pipeline at one end of the ventilation branch pipe 202 away from the compost bucket 1 to the multiple branch pipes, the resistance encountered by the airflow will also increase due to the reduction of the flow area, and each branch pipe of the ventilation branch pipe 202 can be filled with gas. By introducing airflow from the converging pipeline at the side of the ventilation branch pipe 202 away from the compost bucket 1, each pipeline is filled with gas into the ventilation branch pipe 202, and then flows to the inside of the compost bucket 1.

[0027] like Figure 1 to Figure 6As shown, the temperature and humidity adjustment mechanism 3 includes a connecting pipe 301, a shunt pipe 302, an adjustment collection pipe 303, a spray delivery pipe 304, a temperature and humidity controller 305 and a water extraction hose 306. The connecting pipe 301 is connected to the side of the outside of the compost bucket 1 away from the ventilation component 2, and is evenly distributed from top to bottom. The interior of the connecting pipe 301 and the interior of the ventilation duct 201 are connected to the interior of the compost bucket 1. A one-way valve mechanism 8 is also provided inside the connecting pipe 301. A shunt pipe 302 is provided on the side of the connecting pipe 301 away from the compost bucket 1. The side of the shunt pipe 302 close to the compost bucket 1 is the same as the ventilation branch pipe 202. Several pipeline branches are connected to the interior of the connecting pipe 301, and then on the side away from the compost bucket 1, there is a total pipeline collected as the adjustment collection pipe 303. A spray delivery pipe 304 that is also bent downward in an L shape is arranged on the side of the shunt pipe 302 away from the compost barrel 1. A temperature and humidity controller 305 is arranged on the spray delivery pipe 304. The temperature and humidity controller 305 adjusts the temperature and controls the flow rate of the water mist transported inside the spray delivery pipe 304. The water passes through the inside of the spray delivery pipe 304 after atomization and heating, and flows to the regulating collection pipe 303. The regulating collection pipe 303 is transported to the shunt pipe 302 through a general pipeline. The shunt pipe 302 is connected to several connecting pipes 301. When passing through the one-way valve mechanism 8 inside the connecting pipe 301, the flow area becomes smaller, the pressure increases, the flow rate decreases, and it will also be blocked, so as to ensure that the water mist rushes into the inside of other connected shunt pipes 302.

[0028] The discharge mechanism 4 arranged at the lower side of the outer side of the compost bucket 1 includes a bottom support ring 401, a discharge port 402, a discharge plug 403, a filter hole 405, a drain pipe 406, an arc block 407, an extrusion block 408 and an extrusion spring 409. Among them, an inclined surface with an edge inclined toward the center is arranged at the inner lower side of the compost bucket 1, and a discharge port 402 is opened at the center of the outer lower end of the compost bucket 1. The inclined surface at the inner lower end of the compost bucket 1 gathers the organic fertilizer inside the compost bucket 1 toward the center, so as to facilitate the delivery from the inner part of the discharge port 402. A bottom support ring 401 is fixedly connected to the outer lower end of the compost bucket 1, and a plurality of evenly distributed extrusion blocks 408 are arranged at the inner lower end edge of the bottom support ring 401. The upper surface of the extrusion block 408 is an inclined surface with a spiral arc, and a discharge plug 403 is arranged inside the bottom support ring 401. A cavity 404 is opened inside the discharge plug 403. A plurality of evenly distributed filter holes 405 are provided at the upper end of the cavity 404, and a drain pipe 406 is provided at the lower side of the outside of the discharge plug 403. The inside of the drain pipe 406 is connected to the inside of the cavity 404, and the upper end of the discharge plug 403 can be inserted into the inside of the discharge port 402 to block the discharge port 402. A plurality of evenly distributed arc-shaped blocks 407 are provided on the outer wall of the discharge plug 403, and the bottom surface of the arc-shaped blocks 407 is also an inclined surface with a spiral arc, which can be fitted with the upper surface of the extrusion block 408, such as Fig. 9 and Fig.11 As shown, after rotating and extruding and tightening, the discharge plug 403 can just press against the inside of the discharge port 402, thereby completing the installation of the discharge plug.

[0029] An extrusion spring 409 is arranged inside the bottom bracket ring 401, and the extrusion spring 409 presses the discharge plug 403 downwards, and when the discharge plug 403 is removed, the extrusion spring 409 assists the downward pressure of the discharge plug 403, and squeezes and pops out the discharge plug 403. After the organic fertilizer is fermented inside the compost bucket 1, the fertilizer inside the compost bucket 1 is stirred by the stirring component 5.

[0030] The one-way valve mechanism 8 includes a connecting sleeve 801, a hollow valve ball 802 and a one-way connecting hole 803. The connecting sleeve 801 is arranged inside the connecting pipe 301 and the ventilation duct 201. A hollow valve ball 802 is arranged inside the connecting sleeve 801, and clamps for matching the hollow valve ball 802 are arranged on both sides of the connecting sleeve 801 where the through holes are opened. The hollow valve ball 802 can move to both sides inside the connecting sleeve 801 to block the holes on both sides inside the connecting sleeve 801, and a plurality of uniformly distributed one-way connecting holes 803 are opened on the edge of one side of the outer side of the connecting pipe 301 facing the inside of the compost bucket 1. When the hollow valve ball 801 inside the connecting sleeve 801 rolls inward, the through hole on the side facing the compost bucket 1 is blocked, and the connecting sleeve 801 can pass airflow or water mist into the inside of the compost bucket 1 through the one-way connecting hole 803. When the hollow valve ball 802 inside the connecting sleeve 801 rolls toward the side away from the compost bucket 1, the inside of the connecting sleeve 801 can be blocked, and the pipeline provided with the one-way valve mechanism 8 is blocked. When the compost bucket 1 generates gas due to fermentation and the internal pressure is increased, the one-way valve mechanism 8 is expanded, causing the hollow valve ball 802 to block the pipeline, ensuring the airtightness of the inside of the compost bucket 1. In order to prevent the expansion and deformation of the compost bucket 1 due to the expansion inside the compost bucket 1, an air outlet pipe 204 is provided at the lower side of the outer rear end of the compost bucket 1, and a pressure relief valve 205 is provided at the rear end of the air outlet pipe 204. The pressure relief valve 205 can ensure that when the air pressure inside the compost bucket 1 is too high, the pressure inside the compost bucket 1 is promptly relieved.

[0031] Second embodiment: like Fig.13 and Fig.14 As shown, a stirring assembly 5 is provided on the lower side of the sealed barrel cover 6, and the stirring assembly 5 includes a gear ring 501, a driving rod 502, a driven gear 503 and a stirring rod 504. Among them, a gear ring 501 is provided inside the sealed barrel cover 6, and the teeth of the gear ring 501 face inward, and a driving rod 502 is rotatably connected to the upper end of the inner part of the sealed barrel cover 6. The lower side of the driving rod 502 is rotatably connected to a driven gear 503 at the other end connected to the sealed barrel cover 6, and the driven gear 503 and the inner part of the gear ring 501 are meshed together. The driving rod 502 is driven by a motor fixedly connected to the upper side of the outer side of the sealed barrel cover 6, and the driven gear 503 is driven to rotate inside the sealed barrel cover 6. A stirring rod 504 is fixedly connected to the lower side of the driven gear 503. The middle of the stirring rod 504 is bent, so that when the driven gear 503 drives the stirring rod 504 to rotate, the stirring head at the lower end of the stirring rod 504 can swing to increase the uniformity of mixing the organic fertilizer inside the compost bucket 1. Fig.13As shown, the lower end of the stirring rod 504 is a head with a plurality of long rods on the surface, which can increase the efficiency and uniformity of stirring the organic fertilizer inside the compost bucket 1 when the stirring rod 504 rotates. The range of rotation of the stirring rod 504 will not allow the bottom end to scratch the barrel wall of the compost bucket 1.

[0032] Based on the above inventive concept, the application of the present invention in organic fertilizer fermentation may include the following: In the second temperature stage of organic fertilizer fermentation, the preset temperature is controlled at 52~62℃, the preset humidity of organic fertilizer fermentation is maintained at 55%~60%, and the preset temperature of the second temperature stage of organic fertilizer fermentation shall not exceed 70℃. Among them, the second temperature stage of organic fertilizer fermentation is the high temperature stage of organic fertilizer fermentation.

[0033] Set 3 temperature gradients: 45℃, 55℃, 65℃; simultaneously set 3 humidity gradients: 50%, 60%, 70%.

[0034] Step 1: Material preparation: Mix cow dung and straw in proportion and adjust the water content to 70%. Weigh 10kg of the mixture into each fermentation tank, add 0.1% (mass ratio) fermentation agent, and stir evenly.

[0035] The second step is instrument debugging: calibrate temperature, humidity sensors and control devices to ensure precise control.

[0036] The third step is to start fermentation: place the fermentation tank in a constant temperature incubator and start fermentation according to the set temperature and humidity parameters for 21 days.

[0037] The fourth step is data monitoring: record the temperature and humidity regularly every day; measure the pH value every 3 days; measure the organic matter, total nitrogen, total phosphorus and total potassium content on the 7th, 14th and 21st days; and detect the mortality rate of Escherichia coli and Ascaris eggs on the 21st day.

[0038] The effect of temperature on fermentation was observed. During the heating stage of 1 to 2 days, each temperature treatment rose from ambient temperature to near the set temperature. The 45℃ treatment had the slowest temperature rise, reaching 43.5℃ after 2 days; the 55℃ treatment reached 53.8℃ after 1.5 days; and the 65℃ treatment reached 63.2℃ within 1 day.

[0039] In the high temperature stage, the 55℃ and 65℃ treatments quickly entered the high temperature stage and maintained within the set temperature fluctuation range of ±2℃. The temperature of the 45℃ treatment rose slowly, reaching only 50.2℃ at its highest.

[0040] During the cooling stage, the temperature in the 55℃ treatment started to drop on the 15th day and dropped to 48.5℃ on the 21st day; the temperature in the 65℃ treatment started to drop on the 13th day and dropped to 55.3℃ on the 21st day; the temperature in the 45℃ treatment started to drop on the 18th day and dropped to 42.1℃ on the 21st day.

[0041] Simultaneous analysis of the effect of humidity on fermentation: First, the moisture content was observed synchronously. In the first three days, the moisture content of each humidity treatment decreased slightly, with the 50% humidity treatment dropping to 48.5%, the 60% humidity treatment dropping to 57.2%, and the 70% humidity treatment dropping to 68.3%. Subsequently, the moisture content of the 50% humidity treatment slowly dropped to 45.1%, the 60% humidity treatment remained stable, and the 70% humidity treatment slightly increased to 71.2% on the 10th day due to poor ventilation.

[0042] Then in the fermentation process, the fermentation process was slow when the humidity was 50%, the material was dry, and there was obvious caking; the fermentation was normal when the humidity was 60%, and the material was loose; the material was moist and had an odor when the humidity was 70%, and there were obvious signs of anaerobic fermentation.

[0043] The following nine groups of permutations and combinations are carried out according to different temperatures and different humidities: 45°C, 50% humidity is comparative example one, 45°C, 60% humidity is comparative example two, 45°C, 70% humidity is comparative example three, 55°C, 50% humidity is comparative example four, 55°C, 60% humidity is this scheme, 55°C, 70% humidity is comparative example five, 65°C, 50% humidity is comparative example six, 65°C, 60% humidity is comparative example seven, and 65°C, 70% humidity is comparative example eight.

[0044] Combining this scheme with 55℃ and 60% humidity and the other eight comparative schemes, a comparative analysis was conducted through pH value, organic matter content (%), total nitrogen content (%), total phosphorus content (%), total potassium content (%), Escherichia coli mortality (%) and Ascaris egg mortality (%).
