Description

Technical Field

[0001] The present invention relates to the technical field of utilization of mechanical waste, and particularly to a combined fermentation device for livestock and poultry manure and vegetable straws. Background Art

[0002] At present, the main utilization ways of vegetable waste include direct field return, biogas production, feed production, and compost production. The operation process of direct field return is simple, but it is easy to cause environmental pollution. Especially in the high-temperature period in summer, the plants are easy to rot, resulting in the spread of harmful pathogenic bacteria. Vegetable residues can produce biogas to obtain energy, but the required conditions are relatively harsh, the process is complex, and the final wastewater and waste residues need secondary treatment. Although the fermentation time for feed production is short, it requires aseptic operation and is not suitable for large-scale production. Compost production can harmlessly treat vegetable residues through high-temperature fermentation and convert the waste into fertilizer, effectively controlling the spread of harmful pathogenic bacteria. For example, through the combined fermentation of livestock and poultry manure and vegetable straws, it is an effective way for the harmless treatment and resource utilization of vegetable waste. In the current compost fermentation tank, after pre-treating livestock and poultry manure and vegetable straws, they are piled in the tank, and then regularly stirred by a stirring device. The thickness of the three-dimensional compost is relatively large, and there is an obvious difference between the internal temperature and the external temperature. Only by stirring for disturbance, it is impossible to turn the compost materials as a whole, and it is difficult to balance the internal and external temperature differences. Overall spreading will increase the floor area. Therefore, there is an urgent need for a combined fermentation device for livestock and poultry manure and vegetable straws to solve the above problems. Summary of the Invention

The terms used in the embodiments part of the present invention are only used to explain the specific embodiments of the present invention, and are not intended to limit the present invention. The embodiments of the present application will be described below with reference to the accompanying drawings.

[0018] Embodiment 1: As Figure 1 - Figure 2 shown, a combined fermentation device for livestock and poultry manure and vegetable straws includes a fermentation tank 1. The fermentation tank 1 is a three-dimensional fermentation tank 1, and structures such as a forward and reverse motor 9, a feed inlet 28, an exhaust port, and an air inlet pipe are provided at the top. A ladder 30 is provided on one side for users to perform feeding operations. A viewing window 31 and a sampling port 32 are provided in the middle and lower parts for users to perform observation and sampling operations. The viewing window 31 and the sampling port 32 comply with the sealing treatment regulations to ensure the sealing of the internal space of the fermentation tank 1. A discharge port 33 is provided at the bottom of the fermentation tank 1 to regularly discharge the fermented products from the bottom of the fermentation tank 1.

[0019] Reference Figure 1As shown, a number of fermentation platforms are vertically arranged in the fermentation tank 1, and independent fermentation spaces can be formed between the fermentation platforms at each layer. Each fermentation platform includes: A pair of trays, refer to Figure 3 As shown, it is a pair of trays, namely the main tray 2 and the auxiliary tray 3 respectively. The structures of the main tray 2 and the auxiliary tray 3 are adjacent. In order to ensure a more effective fermentation space, the height of the auxiliary tray 3 can be appropriately reduced according to requirements. Its function is to temporarily store the materials (livestock and poultry manure and vegetable straws) released by the main tray 2; Among them, a number of blanking channels 4 are circumferentially opened on the upper edges of the main tray 2 and the auxiliary tray 3; at least one material pushing plate 5 is arranged on both the main tray 2 and the auxiliary tray 3. The material pushing plate 5 is configured to rotate along the circumferential direction of the tray and periodically push the materials to pass through the blanking channel 4; Refer to Figure 4 - Figure 5 In the main tray 2 and the auxiliary tray 3, cavities 6 are opened near the top surface positions. An inner disk 7 is rotatably connected in the cavity 6. Through holes 8 corresponding to the blanking channels 4 are opened on the inner disk 7. The inner disk 7 is configured to rotate, drive the through holes 8 to coincide with the blanking channels 4 to open the openings of the blanking channels 4, which is defined as the first state, or drive the through holes 8 to be misaligned with the blanking channels 4 to close the openings of the blanking channels 4, which is defined as the second state; and the initial states of the inner disks 7 in the main tray 2 and the auxiliary tray 3 are in different states respectively.

[0020] Among them, a rotating shaft 10 is installed in the fermentation tank 1. One end of the rotating shaft 10 is linked with the output shaft of the forward and reverse motor 9, and the other end passes through each pair of trays in sequence; and one end of each material pushing plate 5 is assembled on the rotating shaft 10, and each material pushing plate 5 rotates synchronously with the rotating shaft 10.

[0021] By driving the rotating shaft 10 to rotate through the forward and reverse motor 9, the material pushing plates 5 are driven to rotate, and the materials on the trays are pushed to move. When the corresponding tray is in the first state, at this time, the materials on the tray can be pushed to the opening of the blanking channel 4, and the materials pass through the blanking channel 4 and fall onto the lower tray. When the corresponding tray is in the second state, the material pushing plate 5 pushes the materials to be laid flat on the corresponding tray.

[0022] Among them, in this embodiment, refer to Figure 6 , a number of elastic material plates 13 are vertically installed at the blanking channel 4. The adjacent elastic material plates 13 are staggered. The elastic material plates 13 are obliquely arranged in the blanking channel 4, and one end is movably connected to the inner wall of the blanking channel 4. A vibration spring 14 is installed between the elastic material plates 13 and the blanking channel 4. When the materials are falling, they will contact and squeeze the elastic material plates 13. The elastic material plates 13 compress the vibration spring 14, and under the action of the vibration spring 14, the materials on the elastic material plates 13 are jittered, so that they are scattered during the falling process and avoid falling in blocks.

[0023] In this embodiment, the material falls from the feed inlet 28 onto the uppermost main tray 2. After a period of fermentation, the inner tray 7 inside the uppermost main tray 2 is controlled to rotate (the driving of the inner tray 7 can be achieved by setting a driving motor or the like, and this feature can adopt the existing solutions in the prior art to realize the rotation control of the inner tray 7). It switches from the second state to the first state. Then, the forward and reverse motor 9 is started to drive the rotating shaft 10 to rotate, thereby driving each baffle plate 5 to rotate, pushing the material on the main tray 2 to move, and pushing the material on the main tray 2 to the opening of the blanking channel 4. The material passes through the blanking channel 4 and falls onto the lower auxiliary tray 3 for the next step of fermentation. At the same time, the main tray 2 located on the upper layer can continue to carry the material for fermentation. By repeating the above operations, in this embodiment, the state of the inner tray 7 in the auxiliary tray 3 can be first switched from the second state to the first state. At this time, the forward and reverse motor 9 is started, and the material on the main tray 2 is leveled, and the auxiliary tray 3 performs the blanking process. Then, the state of the inner tray 7 in the auxiliary tray 3 is switched from the first state to the second state, and the state of the inner tray 7 in the main tray 2 is switched from the second state to the first state. The forward and reverse motor 9 is started, the material on the auxiliary tray 3 is leveled, and the main tray 2 performs the blanking process. By repeating this process, the layer-by-layer blanking and fermentation work is completed.

[0024] Embodiment 2: On the basis of Embodiment 1, in this embodiment, the baffle plate 5 includes a fixed part 51 and a triangular swinging part 52. One end of the fixed part 51 is assembled on the rotating shaft 10 and rotates synchronously with the rotating shaft 10. One side of the triangular swinging part 52 is hinged to the fixed part 51, and a spring structure is installed at the hinged part. Moreover, the hinged directions of the triangular swinging parts 52 on the main tray 2 and the auxiliary tray 3 are opposite. When the triangular swinging part 52 is configured to be under force in the first direction, it swings around the hinged part. When it is under force in the second direction, its swinging is restricted by the fixed part 51. The first direction and the second direction are opposite directions in which the triangular swinging part 52 is subjected to relative to the hinged part. Refer to Figure 3 As shown, one side of the triangular swinging part 52 is hinged to the fixed part 51, and the corresponding surface of this side of the triangular swinging part 52 corresponds to the bottom surface of the fixed part 51, so that Figure 3 taking the baffle plate 5 at the bottom in

[0025] as an example, when the triangular swinging part 52 is subjected to a force from left to right, at this time, the triangular swinging part 52 will rotate around the hinged part. When the triangular swinging part 52 is subjected to a force from right to left, at this time, the fixed surface of the triangular swinging part 52 will contact the bottom surface of the fixed part 51, thereby restricting the triangular swinging part 52 from continuing to rotate and stabilizing the state of the triangular swinging part 52. In this embodiment, when the inner disk 7 in the main tray 2 rotates from the second state to the first state, the opening of the blanking channel 4 is in an open state. The forward and reverse motor 9 drives the rotating shaft 10 to rotate, thereby driving each material deflector 5 to rotate. At this time, the material deflector 5 located in the main tray 2 is subjected to a force in the second direction. At this time, the state of the triangular swing part 52 is fixed, and it can push the material into the blanking channel 4. At the same time, the inner disk 7 in the auxiliary tray 3 rotates from the first state to the second state, and the triangular swing part 52 located in the auxiliary tray 3 is subjected to a force in the first direction. At this time, the triangular swing part 52 can swing around the hinged part, avoiding large-scale disturbance of the material on the auxiliary tray 3, and at the same time, it can evenly stir the material on the upper layer of the auxiliary tray 3 to avoid local accumulation of the material.

[0026] Further, in this embodiment, a gas channel 11 is provided in the fixed part 51, and a plurality of air holes 12 are provided at the bottom of the fixed part 51. The air holes 12 can be communicated with an external oxygen supply device through a gas pipeline 29. The construction personnel can arrange the gas pipeline 29 according to the specific situation as long as it does not affect the normal operation of the equipment. When the triangular swing part 52 swings, the corresponding surface blocks or opens the air holes 12.

[0027] That is, during the process of evenly stirring the material on the upper layer of the auxiliary tray 3 to avoid local accumulation of the material, the air holes 12 are opened at the same time, and gases such as oxygen can be released to a specified tray in a directed manner to participate in the fermentation work.

[0028] Embodiment 3: On the basis of Embodiment 1 or Embodiment 2, in this embodiment, the rotating shaft 10 is connected to the output shaft of the forward and reverse motor 9 through a first linkage mechanism. The first linkage mechanism is configured to drive the rotating shaft 10 to rotate synchronously with the output shaft. The rotating shaft 10 slides freely along the axis direction of the output shaft. An electric telescopic mechanism 15 (such as an electric telescopic cylinder, and this feature can adopt the existing solutions in the prior art) is installed at the top of the fermentation tank 1. The telescopic end of the electric telescopic mechanism 15 is connected to the rotating shaft 10, and the electric telescopic mechanism 15 drives the rotating shaft 10 to move along the axis direction of the output shaft; and the material deflector 5 in the auxiliary tray 3 is also connected to the rotating shaft 10 through a first linkage mechanism. That is, an outer cylinder 17 can be provided at the center of each material deflector 5, and then an inner shaft 16 is provided at the position of the outer cylinder 17 corresponding to the rotating shaft 10 and the material deflector 5. In this way, the rotating shaft 10 can move freely up and down without driving the outer cylinder 17 and the material deflector 5 to move, and the rotation of the rotating shaft 10 can synchronously drive the material deflector 5 to rotate. As the rotating shaft 10 moves, the distance between the material deflector 5 in the main tray 2 and the main tray 2 is adjusted.

[0029] Among them, refer to Figure 2As shown, the first linkage mechanism includes an inner shaft 16 and an outer cylinder 17; the inner shaft 16 is coaxially connected to the rotating shaft 10, and a plurality of limiting strips 18 are arranged on the outer surface of the inner shaft 16 along the circumferential direction; the outer cylinder 17 is coaxially connected to the output shaft of the forward and reverse motor 9, and limiting grooves 19 are provided at the positions corresponding to each limiting strip 18 on the inner wall of the outer cylinder 17; the inner shaft 16 is inserted into the outer cylinder 17, and the limiting strips 18 are inserted into the corresponding limiting grooves 19.

[0030] In this embodiment, the electric telescopic mechanism 15 can drive the rotating shaft 10 to move in the vertical direction. Among them, during the movement of the rotating shaft 10, the deflector plate 5 in the main tray 2 can be synchronously driven to move up and down, while the deflector plate 5 in the auxiliary tray 3 is in the initial state, and under the action of the first linkage mechanism, the deflector plate 5, the rotating shaft 10 and the output shaft of the forward and reverse motor 9 can perform synchronous rotation work.

[0031] Among them, a second linkage mechanism is installed between the inner disk 7 and the rotating shaft 10, and the movement of the rotating shaft 10 includes: The first moving section is the first stage when the deflector plate 5 moves vertically upward. When the rotating shaft 10 is moving in the first moving section, the distance between the deflector plate 5 on the main tray 2 and the main tray 2 is adjusted; The second moving section is the second stage when the deflector plate 5 continues to move vertically upward. The second linkage mechanism drives the inner disk 7 in the main tray 2 to switch from the first state to the second state, and at the same time drives the inner disk 7 in the auxiliary tray 3 to switch from the second state to the first state.

[0032] In this embodiment, referring to Figure 7 ( Figure 7 is the perspective view of the bottom of the inner disk 7), the second linkage mechanism includes a first pressure plate 20 and a second pressure plate 21; the first pressure plate 20 is coaxially installed on the rotating shaft 10; the second pressure plate 21 is coaxially installed on the inner disk 7, and a return spring 22 is installed in the second pressure plate 21; first pressure teeth 23 and second pressure teeth 24 are respectively arranged on the corresponding surfaces of the first pressure plate 20 and the second pressure plate 21, and the second pressure plate 21 is configured to: when the first pressure teeth 23 contact the second pressure teeth 24, squeeze the second pressure teeth 24 and drive the second pressure teeth 24 to rotate, and the inner disk 7 rotates synchronously with the second pressure plate 21. For the first pressure teeth 23 and the second pressure teeth 24, reference can be made to Figure 7 form, which has an arc-shaped inclined surface. After the two contact, since the state of the first pressure teeth 23 is fixed, the second pressure teeth 24 can rotate and fit along the corresponding arc-shaped inclined surface. After the two are separated, under the action of the return spring 22, it can automatically drive the reset rotation.

[0033] In this embodiment, it moves through the rotating shaft 10. During the first moving section, it drives the distance adjustment between the material pushing plate 5 in the main tray 2 and the main tray 2. At this time, the inner tray 7 in the main tray 2 is in the first state, and the inner tray 7 in the auxiliary inner tray 7 is in the second state. First, control the movement of the rotating shaft 10 to make the material pushing plate 5 at the highest position of the first moving section. Then drive the rotating shaft 10 to rotate. At this time, it can drive the material pushing plate 5 in the main tray 2 to rotate, and push the material at the highest layer in the main tray 2 into the blanking channel 4 and drop it onto the lower auxiliary tray 3. Then gradually adjust the rotating shaft 10 downward, and at the same time make the material pushing plate 5 gradually approach the main tray 2, so as to transfer the materials on the main tray 2 to the auxiliary tray 3 layer by layer until all the materials are transferred to the auxiliary tray 3; Next, drive the rotating shaft 10 to move it to the second moving section. At this time, the first pressing tooth 23 contacts the second pressing tooth 24, squeezes the second pressing tooth 24 and drives the second pressing tooth 24 to rotate. The inner tray 7 rotates synchronously with the second pressing plate 21. The inner tray 7 in the main tray 2 switches from the first state to the second state. At the same time, drive the inner tray 7 in the auxiliary tray 3 to switch from the second state to the first state. Since the state of the material pushing plate 5 in the auxiliary inner tray 7 always remains in the initial state, at this time, the forward and reverse motor 9 rotates in the reverse direction, and the material pushing plate 5 in the auxiliary inner tray 7 transfers the materials in the auxiliary tray 3 downward as a whole and transfers them to the main tray 2 on the next layer, realizing the overall turnover of the materials. Compared with stirring, it can better and more fully invert the upper and lower layers of the materials and improve the fermentation efficiency.

[0034] Example 4, on the basis of Example 3, referring to Figure 3 - Figure 7 As shown, optionally, slopes 25 are provided at each blanking channel 4 of the main tray 2 and the auxiliary tray 3, and the vertical surface of the slope 25 corresponds to the blanking channel 4. One end of the material pushing plate 5 is assembled on the rotating shaft 10 through a sleeve 26, and a compression spring 27 is provided on the sleeve 26. The compression spring 27 is configured to provide the material pushing plate 5 with space to move vertically upward through compression deformation. The vertical surface of the slope 25 can cooperate with the triangular swinging part 52 to fully push the materials pushed by the triangular swinging part 52 into the blanking channel 4 and accelerate the blanking efficiency.
