[0012] In the bidirectional flow-guiding drum organic fertilizer production device described above, the lifting plate is parallel to the axial direction of the drum. The lifting plate lifts the material while rotating with the drum. During the lifting and lowering process, the material is fully mixed and the contact between the material and oxygen is promoted, thereby enhancing the effect of aerobic fermentation.

In the bidirectional flow-guiding drum organic fertilizer production device described above, the drum is provided with ventilation holes, the distance between the ventilation holes and the drum feed end is smaller than the distance between the ventilation holes and the drum discharge end, and the ventilation holes are connected to the suction fan via ventilation pipes. The ventilation pipes pass through the drum and then through the feed drum and feed pipe to avoid interference between the ventilation pipes and the drum during rotation.

[0021] A temperature sensor and a moisture content detection component are arranged in the drum. The drum is also provided with a heating component. The heating component, the temperature sensor, the moisture content detection component and the suction fan are all connected with the control unit.

Unless otherwise specified, all technical and scientific terms used in the present invention have the same meaning as commonly understood by those skilled in the art to which the present invention belongs.

[0038] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless otherwise clearly indicated in the present invention, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "include" and / or "comprising" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or their combinations;

[0039] As described in the background art, the organic fertilizer production device in the prior art has problems such as large floor space. In order to solve the above technical problems, the present invention proposes a two-way flow-guiding drum organic fertilizer production device.

[0040] Example 1

[0041] In a typical embodiment of the present invention, referring to Figure 1 As shown, a two-way flow-guiding drum organic fertilizer production device includes a drum 4, which can rotate along the central axis of the drum 4 relative to the base. A feed drum 2 is provided inside one end of the drum 4. The outer diameter of the feed drum 2 is smaller than the inner diameter of the drum 4, and the length of the feed drum 2 is smaller than the length of the drum 4. A flow-guiding structure is provided on the inner surface of the drum 4, and multiple groups of the flow-guiding structure are provided along the length direction of the drum.

[0042] Each group of guide structures includes a forward guide plate 7, a lifting plate 8 and a reverse guide plate 9 arranged in sequence along the length direction of the drum. The forward guide plate and the reverse guide plate are inclined relative to the central axis of the drum and are arranged in opposite directions. The forward guide plate 7, the lifting plate 8 and the reverse guide plate 9 in each group of guide structures are each arranged in a circle along the inner surface of the drum 4. Figure 2 As shown, a copy plate 8 is provided between two adjacent groups of guide structural members, and the copy plate 8 is staggered with the adjacent forward guide plate or reverse guide plate.

[0043] It should be explained that the forward guide plate 7, the lifting plate 8, and the reverse guide plate 9 are all arranged perpendicular to the inner surface of the drum and can be welded together. In this embodiment, the guide structure is provided along the length direction of the drum 4, i.e., the axial direction, from the feed end to the discharge end. The distance between two adjacent guide structures is less than the length of the lifting plate. For this reason, the lifting plate is staggered with the adjacent forward guide plate or reverse guide plate.

[0044] It can be understood that the forward guide plates in the first group of guide structures are close to the feed barrel 2 of the drum, but the forward guide plates in this group are located outside the feed barrel.

[0045] In addition, the feed cylinder 2 is coaxially arranged with the roller 4. The feed cylinder 2 is located at the feeding end of the roller 4 and is fixed together with the roller. The feed cylinder 2 rotates coaxially. The diameter of the feed cylinder 2 is 1 / 3 to 1 / 4 of the diameter of the roller, which is conducive to ensuring the amount of material entering the roller. Figure 3 As shown, a third guide plate 3 is arranged in the feed barrel 2, the third guide plate 3 is perpendicular to the inner surface of the feed barrel 2, the axial angle between the third guide plate 3 and the roller 4 is 30 to 45 degrees, the guide direction of the third guide plate 3 is the same as the rotation direction of the roller 4, and the direction of the third guide plate 3 is toward the end of the roller 4 away from the feed barrel 2; when the material in the roller 4 is higher than the upper cross-section of the feed barrel, the material in the feed barrel can no longer enter the roller 4, so that the material in the roller maintains the optimal filling amount, which is about 60 to 70%.

[0046] The number of the third guide plates 3 is 3-5. The third guide plates 3 are arranged in a circle around the inner surface of the feed barrel 2. In this embodiment, three third guide plates are provided, and the plurality of third guide plates are evenly arranged in the feed barrel 2.

[0047] It can be understood that the feed barrel 2 is connected to the feed pipe 1, the feed pipe 1 is vertically arranged, the feed pipe 1 is bent toward one side of the feed barrel, and the bent end of the feed pipe 2 is connected to the feed barrel 2, which is used to introduce unprocessed raw materials into the drum. The feed pipe 1 is connected to the feed barrel from top to bottom through a sealing member such as a sealing ring.

[0048] In this embodiment, the drum 4 is a horizontal drum made of stainless steel or carbon steel with an anti-corrosion treatment on the inside. An external insulation layer, preferably polyurethane, is applied to maintain heat during the fermentation process and overcome fermentation hindrances caused by low ambient temperatures. The drum is capable of rotating along its central axis. One end of the drum 4 serves as the feed port, and the other end is provided with a discharge port 10. A discharge plate 11 is provided at the bottom of the discharge port 10, which is inclined downward.

[0049] In order to realize the rotation of the drum, two first gears are provided on the outer surface of the drum 4, and a second gear meshing with the first gear is provided on one side of the drum. The two second gears are set at a set distance between them. The two second gears are fixed to the same rotating shaft. One of the second gears is connected to the power mechanism. The power mechanism drives the first gear to rotate, and then drives the first gear to rotate, so as to realize the rotation of the drum relative to the power mechanism. The power mechanism can be a reduction motor 5, and the reduction motor 5 is connected to the rotating shaft.

[0050] The rotating shaft is rotatably mounted on the base, and the reduction motor is fixed to the base. One side of the base is height-adjustable to allow the roller to be tilted. Specifically, the base is movably supported on a frame or the ground. A wedge can be provided on the bottom side of the base near the feed end of the roller to ensure that the feed end of the roller is higher than the discharge end. The inclination is preferably 2 to 5 degrees. In a preferred embodiment, the preferred inclination is 3 degrees, which ensures that the material can move from the feed end to the discharge end while keeping the movement speed within a reasonable range.

[0051] In addition, considering the fermentation of the material, the drum 4 is provided with ventilation holes, which are connected to the suction fan 12 through a ventilation pipe 13; the air inlet end of the ventilation pipe is fixed to the side of the feed barrel at the feed end of the drum, that is, the ventilation hole is arranged close to the feed end of the drum, and the ventilation pipe 13 passes through the drum and then through the feed barrel to avoid interference between the ventilation pipe and the drum during the rotation of the drum, and is connected to the suction fan, and the suction fan is externally connected to a gas treatment mechanism. Under the action of the suction fan 12, air is taken in from the discharge end of the drum, and the gas is in full contact with the rolling material, accelerating the aerobic fermentation process, and the gas is exhausted from the feed end and enters the gas treatment unit. On the one hand, the intake air can be preheated by contact with the discharge material, so that the feed material is exposed to warm gas. On the other hand, a negative pressure environment can be formed in the drum to avoid the emission of polluted gases.

[0052] In addition, a temperature sensor is provided in the drum to obtain the fermentation temperature information of the material in the drum. The drum is also provided with a heating component, which is specifically a heating resistance wire or a hot air blower. The heating component, temperature sensor, suction fan, and gas treatment mechanism are all connected to the control unit.

[0053] It can be understood that the control unit is a PLC controller or other types of controllers, and the gas treatment mechanism is a commonly used organic waste gas treatment device, which is determined according to the waste gas composition and treatment requirements.

[0054] It should be explained that the angle between the positive guide plate and the drum axis is 10°-20°, specifically 12° or other values, refer to Figure 2 As shown, the guide direction of the positive guide plate is the same as the rotation direction of the drum. The positive guide plate has an axial propulsion force, which pushes the material from the feed end to the discharge end.

[0055] refer to Figure 2 As shown, the angle between the reverse guide plate and the drum axis is 10°-20°, specifically 12° or other values. The guide direction of the forward guide plate is opposite to the rotation direction of the drum. The function of the reverse guide plate is to push the material in the opposite direction, slow down the advancement of the material, extend the residence time of the material, and make the material further fully fermented.

[0056] Among them, reference Figure 2As shown, the lifting plate 8 is parallel to the axis of the drum 4. The lifting plate 8 lifts the material while rotating with the drum. During the lifting and lowering process, the material is fully mixed and the contact between the material and oxygen is promoted, thereby enhancing the effect of aerobic fermentation.

[0057] In addition, the length of the copying plate 8 is greater than the length of the forward guide plate and the reverse guide plate. In some examples, one side of the forward guide plate and the reverse guide plate is curved to fit the inner wall of the drum. The size of the forward guide plate (length × height × thickness) is 40cm × 10cm × 1cm, the size of the reverse guide plate (length × height × thickness) is 40cm × 10cm × 1cm, the copying plate is a straight plate, and the size of the copying plate (length × height × thickness) is 50cm × 10cm × 1cm; it should be explained that the length direction of the copying plate is along the axial direction of the drum.

[0058] In each group of guide structures, considering that the lift plates, forward guide plates and reverse guide plates need to be spaced apart, the number of forward guide plates, lift plates and reverse guide plates is 6-12, for example, 8.

[0059] It can be understood that the number of forward guide plates, transfer plates and reverse guide plates in each group of guide structures is the same.

[0060] In the organic fertilizer production device provided in this embodiment, the drum rotates, and the material 6 enters the drum and rotates with the drum. Under the action of the forward guide plate 6, the lifting plate 8, the reverse guide plate 9 and gravity, it moves from the feed end to the discharge port 10, and is fully contacted with oxygen under the action of the suction fan 12, completing the primary aerobic fermentation of the material. The aerobic fermented material is discharged from the drum through the discharge plate 11 and enters the next organic fertilizer preparation process, such as the post-composting process.

[0061] Example 2

[0062] This embodiment provides a working method of a two-way flow-guiding drum organic fertilizer production device, including the following contents:

[0063] Animal manure (manure is used as raw material and does not require crushing and mixing) such as cow manure with a set moisture content of 55% is fed into the drum through the feed tube. The drum rotates at a set speed such as 0.3r / min, and the suction fan is turned on. As the drum rotates, the material is fully mixed under the drive of the forward guide plate, reverse guide plate and lifting plate, and the entire aerobic fermentation process is completed in the process of being pushed from the feed end to the discharge end of the drum. The processing load of the drum is maintained at 65-70%, the animal manure is kept in the drum for 8 days, and the fermentation temperature is 50-70°C.

[0064] Crushed plant straw (particle size of 2.5-4mm) such as corn straw is added with microbial agents such as auxiliary materials such as wheat bran and rice bran, and after reaching a set moisture content of 50-60%, it is fed into the drum through the feed tube. The drum rotates at a set speed of 0.3r / min, and the suction fan is turned on. As the drum rotates, the material is fully mixed under the drive of the forward guide plate, reverse guide plate and lifting plate. The entire aerobic fermentation process is completed in the process of being pushed from the feed end to the discharge end of the drum. The animal feces stay in the drum for 8.5 days, and the fermentation temperature is 50-70℃.

[0065] After the fermentation is completed, the material is discharged from the drum outlet and enters the next fermentation process.

[0066] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
