Description
Technical Field

The prior art provides a garbage treatment device, which adopts compartmentalized fermentation to treat kitchen waste. Multiple fermentation compartments are distributed along the axial direction and share a stirring shaft. Material transfer ports are provided on the partition plates of adjacent fermentation compartments. It mainly realizes the pushing and transmission of fertilizers in each fermentation compartment along the axial direction by stirring and extruding. However, this method will cause the material at the bottom of the fermentation compartment to be piled up. At the same time, the material away from the material transfer port along the radial direction of the axis will be blocked by the partition plate, which is not conducive to the pushing of the material, resulting in uneven fermentation of the material entering the next fermentation compartment, and ultimately affecting the yield of the fertilizer.

The outer wall of the box is provided with an insulation layer, and the insulation layer is filled with 5mm insulation cotton, which helps to ensure the constant temperature inside the box and is conducive to the fermentation process of the material.
[0049] The pretreatment component 100 is arranged at the upper part of the box body and is connected to the outside through the pretreatment feed port 110. When in use, garbage and auxiliary materials can be put into the rural courtyard garbage treatment device through the pretreatment feed port 110. Below the pretreatment component 100, a pretreatment discharge port 120 is provided. After the material entering the pretreatment component 100 is pretreated, it can enter the fermentation component 200 through the pretreatment discharge port 120.
[0050] The fermentation assembly 200 is arranged below the pretreatment assembly 100, and the fermentation assembly 200 includes a first fermentation bin 210 and a second fermentation bin 220. The first fermentation bin 210 is arranged directly below the pretreatment discharge port 120, and is provided with a first feed port corresponding to the pretreatment discharge port 120, that is, the pretreated material can enter the first fermentation bin 210 from the first feed port; the second fermentation bin 220 is arranged on one side of the first fermentation bin 210 along the width direction of the first fermentation bin 210, that is, the second fermentation bin 220 and the first fermentation bin 210 are arranged side by side, and the first fermentation bin 210 and the second fermentation bin 220 are arranged side by side.

[0051] The first stirring component 310 is arranged in the first fermentation bin 210 along the length direction of the first fermentation bin 210, and the first fermentation bin 210 is used to push the material located in the first fermentation bin 210 to the second fermentation bin 220 along the radial direction of the first stirring component 310; specifically, the first stirring component includes a main shaft (stirring main shaft), stirring blades, a support seat, an auxiliary bearing and a motor, etc. The main shaft is arranged in the first fermentation bin 210 along the length direction of the first fermentation bin 210, and a plurality of stirring blades are arranged on the main shaft at intervals along the axial direction of the main shaft. The stirring blades are paddle-type stirring blades, the support seat and the auxiliary bearings are arranged at both ends of the main shaft, and the motor is arranged at one end of the main shaft. When in use, the motor drives the main shaft and the stirring blades to rotate around the axis of the main shaft. Since the axis of the main shaft is perpendicular to the width direction of the first fermentation bin 210, when the main shaft rotates, the material in the first fermentation bin 210 will move toward the second fermentation bin 220 along the radial direction of the main shaft as the main shaft rotates.
[0052] The purification and collection component 400 is connected to the pretreatment component 100 and the fermentation component 200 , and is used to collect and process the waste liquid and waste gas in the pretreatment component 100 and the fermentation component 200 .
[0053] See also Figures 1 to 3 It can be understood that the rural garden waste treatment device provided by the embodiment of the utility model can realize segmented fermentation of materials by setting the first fermentation bin 210 and the second fermentation bin 220 at intervals, so that the materials thrown into the rural garden waste treatment device at different times can be fermented separately, that is, the independent fermentation of raw and cooked materials can be realized, which can make the quality of the fermentation product better and better meet the user's demand for fertilizer use; in addition, the first fermentation bin 210 and the second fermentation bin 220 are arranged side by side, and the first stirring component 310 is arranged in the first fermentation bin 210 along its length direction, so that the first stirring component 310 can not only stir the materials in the first fermentation bin 210, but also push the materials in the first fermentation bin 210 to the second fermentation bin 220 along the radial direction of the first stirring component 310 itself through the first transfer port 250; furthermore, by setting the pretreatment component 100 and the purification collection component 400, the materials can be treated before and after fermentation respectively, which not only improves the material treatment efficiency of the rural garden waste treatment device, but also plays a role in protecting the environment.
[0054] Compared with the prior art, the rural garden waste treatment device provided by the embodiment of the utility model enables the first stirring component to push the material in the first fermentation bin 210 to the second fermentation bin 220 along its own radial direction through the first transfer port 250. In this way, the material with the best fermentation degree at the bottom of the first fermentation bin 210 can be pushed to the second fermentation bin 220 first, that is, the fermentation degree in the first fermentation bin 210 can be made from good to poor, and then enter the second fermentation bin 220 in sequence. In this way, the retention time of imperfectly fermented materials in the first fermentation bin 210 can be extended, and the uniformity of the fermentation treatment of the internal materials in the first fermentation bin 210 can be improved, that is, the uniformity of the materials entering the second fermentation bin 220 can be improved, and the problem of uneven fermentation caused by the materials entering the first fermentation bin 210 at different times or the materials being in different positions in the first fermentation bin 210 can be weakened. In this way, the material treatment effect of the rural garden waste treatment device can be improved, and the final fertilizer yield can be improved.
[0055] Continue to read 1 to Figure 3 In an optional embodiment of the present invention, the fermentation component 200 further includes a third fermentation bin 230 and a fourth fermentation bin 240. The third fermentation bin 230 is disposed directly below the second fermentation bin 220. At the same time, a second feed port corresponding to the first discharge port 222 is disposed on the upper side of the third fermentation bin 230, that is, the material can enter the third fermentation bin 230 through the first discharge port 222 and the second feed port; the fourth fermentation bin 240 is disposed on one side of the third fermentation bin 230 along the width direction of the third fermentation bin 230, that is, the third fermentation bin 230 and the fourth fermentation bin 240 are arranged side by side. A second partition 260 is provided between the fermentation bin 230 and the fourth fermentation bin 240, and a preset distance is also provided between the top of the second partition 260 and the top of the fourth fermentation bin 240 for material transfer between the third fermentation bin 230 and the fourth fermentation bin 240. In other words, a second transfer port 270 is provided on the upper side of the second partition 260; a second discharge port 241 communicating with the outside is provided on the side of the fourth fermentation bin 240. During use, the finished fertilizer collection device can be connected to the outside of the second discharge port 241. In this way, the treatment efficiency of the rural courtyard waste treatment device can be improved.
[0056] See also Figures 1 to 3It can be understood that the rural garden garbage treatment device provided by the embodiment of the utility model can further optimize the segmented fermentation structure of the rural garden garbage treatment device by setting the third fermentation bin 230 and the fourth fermentation bin 240, that is, the first fermentation bin 210, the second fermentation bin 220, the third fermentation bin 230 and the fourth fermentation bin 240 can realize the gradient treatment of the material, and the materials thrown into the rural garden garbage treatment device at different times can be more finely treated, so that the materials thrown in each time period can be fully fermented, and at the same time, the mutual influence of materials in different time periods can be avoided, and the uniformity and yield rate of the final finished fertilizer can be improved, which is conducive to reducing costs and increasing efficiency. As fresh materials enter the fermentation bin every day, materials at different fermentation stages can be fermented in different bins in stages, avoiding the mixing of raw and cooked materials and improving the quality of organic fertilizer.
[0057] In addition, the first fermentation bin 210 and the second fermentation bin 220 are located above the third fermentation bin 230 and the fourth fermentation bin 240. According to the principle that hot air flows upward and cold air flows downward, a temperature difference can be generated between the first fermentation bin 210 and the second fermentation bin 220 and the third fermentation bin 230 and the fourth fermentation bin 240, that is, a temperature gradient is generated between the upper and lower fermentation bins. In this way, the material can be placed in different temperature environments at different fermentation stages, which means that the different temperature requirements of the material at different fermentation stages can be met, which is beneficial to improving the fermentation efficiency of each fermentation bin and improving the overall treatment efficiency of the rural yard waste treatment device.
[0058] Continue reading Figures 1 to 3 In an optional embodiment of the utility model, the rural garden waste treatment device also includes a second stirring component 320, a third stirring component 330 and a fourth stirring component 340. The second stirring component 320 is arranged in the second fermentation bin 220 along the length direction of the second fermentation bin 220. The second fermentation bin 220 is used to push the material in the second fermentation bin 220 to the third fermentation bin 230. The specific structure of the second stirring component 320 is similar to that of the first stirring component 310. Specifically, please refer to the setting of the first stirring component 310 in the previous text, which will not be repeated here.
[0059] The third stirring component 330 is arranged in the third fermentation bin 230 along the length direction of the third fermentation bin 230. The third fermentation bin 230 is used to push the material in the third fermentation bin 230 to the fourth fermentation bin 240 along the radial direction of the third stirring component 330. Similarly, the specific structure of the third stirring component 330 is similar to that of the first stirring component 310. Specifically, please refer to the setting of the first stirring component 310 in the previous text, which will not be repeated here. Similar to the first stirring component 310, since the axis of the main shaft of the third stirring component 330 is perpendicular to the width direction of the third fermentation bin 230, when the main shaft rotates, the material in the third fermentation bin 230 will move toward the fourth fermentation bin 240 along the radial direction of the main shaft as the main shaft rotates.
[0060] Similar to the aforementioned first fermentation bin 210 and second fermentation bin 220, with this arrangement, the material with the best fermentation degree at the bottom of the third fermentation bin 230 can be pushed to the fourth fermentation bin 240 first, that is, the fermentation degree in the third fermentation bin 230 can be made from good to poor, and then enter the fourth fermentation bin 240 in sequence. In this way, the retention time of imperfectly fermented materials in the third fermentation bin 230 can be extended, and the uniformity of the fermentation treatment of the internal materials in the third fermentation bin 230 can be improved, that is, the uniformity of the materials entering the fourth fermentation bin 240 can be improved, and the problem of uneven fermentation caused by the materials entering the third fermentation bin 230 at different times or the materials in different positions in the third fermentation bin 230 can be weakened. In this way, the effect of the rural courtyard waste treatment device on material treatment can be improved, and the final yield of the fertilizer can be improved.
[0061] The fourth stirring component 340 is arranged in the fourth fermentation bin 240 along the length direction of the fourth fermentation bin 240. The fourth stirring component 340 is used to push the fertilizer in the fourth fermentation bin 240 out of the rural courtyard waste treatment device through the second discharge port 241. It can be understood that the fourth stirring component 340 can not only stir the material in the fourth fermentation bin 240, but also provide a boosting force for leaving the rural courtyard waste treatment device, which is beneficial to the subsequent collection process of the finished fertilizer collection device.
[0062] Continuing to refer to 3, the rural garden garbage treatment device also includes a heating component 500, the heating component 500 is connected to the first fermentation bin 210, and the heating component 500 is used to heat the temperature of the first fermentation bin 210 to a first preset temperature, the first preset temperature is a, wherein the value range of a is 45 to 55°C, for example, the temperature in the first fermentation bin 210 can be heated to 45°C, 47°C, 50°C, 52°C or 55°C;
[0063] The heating component 500 is connected to the second fermentation bin 220, and is used to heat the temperature of the second fermentation bin 220 to a second preset temperature, where the second preset temperature is b, wherein the value range of b is 55-65°C, for example, the temperature in the second fermentation bin 220 can be heated to 55°C, 57°C, 60°C, 62°C or 65°C;
[0064] The heating component 500 is connected to the third fermentation bin 230, and is used to heat the temperature of the third fermentation bin 230 to a third preset temperature, where the third preset temperature is c, wherein the value range of c is 35-50°C, for example, the temperature in the third fermentation bin 230 can be heated to 35°C, 40°C, 45°C or 50°C;
[0065] The heating component 500 is connected to the fourth fermentation bin 240, and the heating component 500 is used to heat the temperature of the fourth fermentation bin 240 to a fourth preset temperature, where the fourth preset temperature is d, wherein the value range of d is 30-45°C. For example, the temperature in the fourth fermentation bin 240 can be heated to 30°C, 33°C, 37°C, 40°C or 45°C.
[0066] The heating component 500 can use a heating blanket. For example, corresponding heating blankets can be arranged along the length direction of the bottom or side wall of the first fermentation bin 210, the bottom or side wall of the second fermentation bin 220, the bottom or side wall of the third fermentation bin 230, and the bottom or side wall of the fourth fermentation bin 240. The temperature in each fermentation bin can be regulated by controlling the heating blanket. It should be noted that the preset temperature is not set to a fixed value, but to two values (start and stop thresholds). Taking the first preset temperature as an example, the heating principle is: if the temperature range of the first fermentation bin 210 is 45-55°C, the start temperature is set to 45°C, and the stop temperature is set to 55°C; when the temperature is ≤45°C, the heating blanket is started; when the temperature is ≥55°C, the heating is turned off. In other words, it is sufficient to ensure that the temperature in the bin is always maintained within this range.
[0067] See also Figures 1 to 3It can be understood that the rural garden garbage treatment device provided by the embodiment of the utility model can heat the first fermentation bin 210, the second fermentation bin 220, the third fermentation bin 230 and the fourth fermentation bin 240 to their appropriate temperature ranges respectively by setting a heating component 500. In this way, the first fermentation bin 210, the second fermentation bin 220, the third fermentation bin 230 and the fourth fermentation bin 240 can respectively meet the temperature requirements of the four stages of aerobic fermentation of materials, namely, heating, high temperature, cooling and aging.

[0081] During the fermentation process, the temperature sensor monitors the temperature changes of the materials in each fermentation bin in real time. If the set threshold is triggered, the heating blanket can be started or shut down according to the preset command to control the temperature of the pile to remain in an optimal state. In addition, the start and stop time and operating parameters of the aeration fan, cold dryer 411 and exhaust fan 412 are set through the touch screen.
