Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural production technology, and more specifically, to a device for treating biogas residue from agricultural organic waste. Background Technology
[0002] In agricultural production, biogas residue is a common organic waste that usually needs to be treated for composting, soil improvement, or resource recycling. However, since biogas residue contains a large amount of water and solid matter, it is necessary to separate the solid and liquid components for more efficient and economical subsequent processing. In existing technologies, solid-liquid separation is usually achieved by screw extrusion, which uses mechanical pushing to squeeze out the liquid from the biogas residue. However, this method has certain limitations, especially when the biogas residue contains hard impurities (such as gravel, metal fragments, or other objects that are difficult to crush). This can easily cause the extrusion components to jam, thereby interrupting the operation of the equipment. This problem not only affects the separation efficiency but may also damage the equipment, increase maintenance costs, and even delay the processing.
[0003] Meanwhile, in order to meet the demand for high-intensity continuous operation in the biogas residue treatment process, the stability of the equipment operation is particularly important. However, the operation of the screw extrusion technology is highly dependent on the driving force of the motor. When the extrusion component is jammed, the transmission of driving force will be abnormal, which can easily lead to motor overload. Motor overload will not only shorten the service life of the equipment, but may also cause the equipment to stop or even pose safety hazards. There is a lack of a solution in the existing technology that can provide effective protection in the case of blockage by hard materials, so as to maintain stable operation of the equipment in the complex biogas residue treatment environment, which has become an urgent problem to be solved. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] In view of the problems existing in the prior art, this utility model provides an agricultural organic waste biogas residue treatment device to solve the technical problem mentioned in the background art that when the extrusion component is stuck, the transmission of driving force will be abnormal, which will easily lead to motor overload.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution: an agricultural organic waste biogas residue treatment device, comprising a mounting frame, on which a filtration mechanism is installed. The filtration mechanism includes a filter cylinder, a central rod, a spiral plate, filter holes, a motor, a feed hopper, a drain pipe, and a discharge pipe. The filter cylinder is mounted on the mounting frame, the central rod rotates inside the filter cylinder, the spiral plate is mounted on the outer wall of the central rod, the filter holes are arranged on the spiral plate, the motor is mounted on the mounting frame, the feed hopper is mounted on the top surface of the filter cylinder, the drain pipe is mounted on the bottom surface of the filter cylinder, and the discharge pipe is mounted on... At the top of the filter cartridge, a protective mechanism is provided between the motor and the central rod. The protective mechanism includes a connecting sleeve, a connecting rod, a slot, a sliding hole, a locking block, a pressure block, a pressure spring, a push block, and an adjustment mechanism. The connecting sleeve is installed at the output end of the motor, the connecting rod is installed at the bottom end of the central rod, multiple sets of locking blocks are distributed on the outer wall of the connecting rod, multiple sets of sliding holes are distributed inside the connecting sleeve, the locking blocks are installed in multiple sets of sliding holes and are slidably connected to the connecting sleeve, the pressure blocks are installed in multiple sets of sliding holes, the pressure springs are installed on the top surface of multiple sets of pressure blocks, and the push block is installed on the top of multiple sets of pressure springs.
[0008] The present invention is further provided that a support frame is installed on the outer wall of the filter cylinder. The support frame is used to support and fix the filter cylinder, so that the filter cylinder remains stable during operation, avoiding tilting or displacement caused by vibration or external force, while improving the safety and reliability of the device operation and effectively extending the service life of the equipment.
[0009] The present invention is further configured such that the bottom ends of the multiple sets of card blocks and the card slots are all arc-shaped and engage with each other. This arc-shaped design makes the engagement between the card blocks and the card slots tighter, while reducing the frictional resistance during engagement and disengagement, thereby reducing the wear of the components, extending the service life, and improving the reliability and flexibility of the protective mechanism.
[0010] The present invention is further configured such that the tops of the multiple sets of card blocks and the push blocks are all arc-shaped and abut against each other. This arc-shaped structural design can increase the contact area between the card blocks and the push blocks, thereby improving the stability of the thrust transmission, while avoiding local stress concentration caused by uneven contact, ensuring that the device is more stable and reliable during operation.
[0011] The present invention is further configured such that a limiting sleeve is installed at the top of the connecting sleeve, and the limiting sleeve is slidably connected to the connecting rod. The setting of the limiting sleeve restricts the movement range of the connecting rod, thereby avoiding misalignment or mechanical jamming caused by excessive offset of the connecting rod during operation. At the same time, it enhances the stability of the device during operation and further improves the safety and reliability of the protective mechanism.
[0012] The present invention is further configured such that the outer wall of the spiral plate is in contact with the inner wall of the filter cylinder. This design can ensure that the waste is fully pushed and compacted when the spiral plate rotates, while avoiding the clogging caused by the waste remaining on the inner wall of the filter cylinder. This improves the efficiency of solid-liquid separation and enhances the cleanliness and ease of maintenance of the device.
[0013] The present invention is further configured such that the adjusting mechanism includes a sliding sleeve, a sliding groove, a rotating sleeve, and a threaded groove. The sliding sleeve is installed on the outside of multiple sets of pressure blocks. Multiple sets of sliding grooves are distributed on the outer wall of the connecting sleeve and are slidably connected to the sliding sleeve. The rotating sleeve is rotatably installed on the top surface of the sliding sleeve. The threaded groove is provided on the outer wall of the connecting sleeve. The inner wall of the rotating sleeve is threadedly connected to the threaded groove. This adjusting mechanism can drive the sliding sleeve to move along the sliding groove by rotating the rotating sleeve, thereby changing the pressure of the pressure block. It can flexibly adjust the thrust of the pressure spring according to actual needs to adapt to the needs of different working scenarios and improve the ease of operation and flexibility of use of the device.
[0014] The present invention is further provided with anti-slip strips on the outer wall of the rotating sleeve. Multiple sets of anti-slip strips are distributed on the outer wall of the rotating sleeve. The anti-slip strips can effectively increase the friction of the outer wall of the rotating sleeve, thereby preventing slippage during the adjustment process. At the same time, it improves the adjustment accuracy and the convenience of operation, allowing users to more easily and accurately operate the adjustment mechanism.
[0015] (III) Beneficial Effects
[0016] Compared with the prior art, this utility model provides an agricultural organic waste biogas residue treatment device, which has the following beneficial effects:
[0017] 1. This device achieves efficient solid-liquid separation of agricultural organic waste by setting up a filter cylinder, a central rod, and a spiral plate. During operation, the waste enters the filter cylinder from the feed hopper. The motor drives the central rod and spiral plate to rotate. The waste gradually moves upward under the push of the spiral plate. The liquid flows out through the filter holes and is discharged from the drain pipe, while the solid material is gradually transported to the top of the filter cylinder by the spiral plate and discharged from the discharge pipe. This design achieves thorough filtration of the liquid and centralized discharge of the solid material, effectively improving the separation efficiency. Furthermore, the close fit between the spiral plate and the inner wall of the filter cylinder ensures uniform separation of waste during the treatment process, reduces residue, and enhances the overall processing capacity of the equipment.
[0018] 2. The protective mechanism provides automatic protection for the device by setting up components such as connecting sleeves, connecting rods, slots, and locking blocks. During the filtration process, when hard objects cause the spiral plate to jam, the connecting rod will overcome the preset force of the compression spring on the push block due to increased resistance, pushing the locking block out of the slot. This allows the connecting rod and connecting sleeve to idle, thereby preventing the motor from being damaged due to overload. This design not only effectively prevents mechanical failure of the equipment in unexpected situations, but also ensures the safe operation of the motor, improving the reliability and service life of the device. In addition, the sliding connection of the limiting sleeve can further limit the movement range of the connecting rod, enhancing the stability and safety of the protective mechanism.
[0019] 3. The adjustment mechanism, through the setting of a sliding sleeve, a sliding groove, a rotating sleeve, and a threaded groove, achieves precise adjustment of the thrust of the pressure spring. By rotating the rotating sleeve to engage with the threaded groove, the sliding sleeve can be moved along the sliding groove, thereby adjusting the position of the pressure block, compressing or releasing the pressure spring, and thus changing the magnitude of the pressure spring's thrust on the push block. Through this adjustment method, the engagement force between the locking block and the locking groove can be flexibly set to adapt to the processing needs of wastes with different hardness. This ensures timely protection of the protective mechanism in abnormal situations and avoids device operation problems caused by insufficient or excessive spring pressure. At the same time, the anti-slip strip on the outer wall of the rotating sleeve improves the convenience and accuracy of the adjustment operation, further optimizing the user experience of the equipment.

[0029] Please see Figures 1-5 An agricultural organic waste biogas residue treatment device includes a mounting frame 1, on which a filtration mechanism is installed. The filtration mechanism includes a filter cylinder 2, a central rod 3, a spiral plate 4, filter holes 5, a motor 6, a feed hopper 7, a drain pipe 8, and a discharge pipe 9. The filter cylinder 2 is mounted on the mounting frame 1, the central rod 3 rotates inside the filter cylinder 2, the spiral plate 4 is mounted on the outer wall of the central rod 3, the filter holes 5 are located on the spiral plate 4, the motor 6 is mounted on the mounting frame 1, the feed hopper 7 is mounted on the top surface of the filter cylinder 2, the drain pipe 8 is mounted on the bottom surface of the filter cylinder 2, and the discharge pipe 9 is mounted on the top surface of the filter cylinder 2. A protective device is installed between the motor 6 and the central rod 3. The protective mechanism includes a connecting sleeve 10, a connecting rod 11, a slot 12, a sliding hole 13, a locking block 14, a pressure block 15, a compression spring 16, a push block 17, and an adjustment mechanism. The connecting sleeve 10 is installed at the output end of the motor 6, the connecting rod 11 is installed at the bottom end of the central rod 3, multiple sets of locking blocks 14 are distributed on the outer wall of the connecting rod 11, multiple sets of sliding holes 13 are distributed inside the connecting sleeve 10, the locking blocks 14 are installed in the multiple sets of sliding holes 13 and are slidably connected to the connecting sleeve 10, the pressure blocks 15 are installed in the multiple sets of sliding holes 13, the compression spring 16 is installed on the top surface of the multiple sets of pressure blocks 15, and the push block 17 is installed on the top of the multiple sets of compression springs 16.
[0030] A support frame 18 is installed on the outer wall of the filter cartridge 2.
[0031] The bottom of the multiple sets of card blocks 14 and the card slots 12 are all set to be arc-shaped and interlocked.
[0032] The tops of multiple sets of card blocks 14 and push blocks 17 are all set to be arc-shaped and abut against each other.
[0033] A limiting sleeve 19 is installed at the top of the connecting sleeve 10, and the limiting sleeve 19 is slidably connected to the connecting rod 11.
[0034] The outer wall of the spiral plate 4 is in contact with the inner wall of the filter barrel.
[0035] In this embodiment, agricultural organic waste enters the filter cylinder 2 through the top feed hopper 7. The start motor 6 drives the central rod 3 to rotate, which in turn drives the spiral plate 4 to rotate. The waste gradually moves upward under the push of the spiral plate 4. During this process, the liquid in the waste flows out through the filter holes 5 and is discharged from the drain pipe 8 at the bottom of the filter cylinder 2, while the solid material remains on the spiral plate 4 and is conveyed upward. When the solid material is conveyed to the top of the filter cylinder 2, it is discharged from the top discharge pipe 9, achieving the final purpose of solid-liquid separation. When a hard object jams inside the filter cylinder, the motor 6 continues to rotate, and the central shaft drives the connecting rod 11 to generate a certain resistance. When the resistance of the connecting rod 11 exceeds the preset force of the compression spring 16 on the push block 17, the outer side of the slot 12 pushes the block 14 out of the slot 12 and slides outward, overcoming the pushing force of the push block 17. At this time, the connecting rod 11 and the connecting sleeve 10 will rotate freely until the operator stops the operation of the motor 6.
[0036] Please see Figures 3-5 As one embodiment of the adjustment mechanism: the adjustment mechanism includes a sliding sleeve 20, a sliding groove 21, a rotating sleeve 22 and a threaded groove 23. The sliding sleeve 20 is installed on the outside of multiple sets of pressure blocks 15. The sliding groove 21 is provided with multiple sets distributed on the outer wall of the connecting sleeve 10 and slidably connected to the sliding sleeve 20. The rotating sleeve 22 is rotatably installed on the top surface of the sliding sleeve 20. The threaded groove 23 is provided on the outer wall of the connecting sleeve 10, and the inner wall of the rotating sleeve 22 is threadedly connected to the threaded groove 23.
[0037] The outer wall of the rotating sleeve 22 is provided with anti-slip strips 24, and multiple sets of anti-slip strips 24 are distributed on the outer wall of the rotating sleeve 22.
[0038] More specifically, when a preset force is required on the push block 17 by the pressure spring 16, the rotating sleeve 22 engages with the threaded groove 23, thereby causing the rotating sleeve 22 to drive the sliding sleeve 20 to move. The sliding sleeve 20 slides along the slide groove 21 and drives multiple sets of pressure blocks 15 to slide along the slide hole 13. The movement of the multiple sets of pressure blocks 15 compresses the multiple sets of pressure springs 16, thereby increasing the pushing force of the pressure spring 16 on the push block 17 and increasing the locking force of the push block 17 on the locking block 14, and vice versa.
[0039] In summary, during the use or operation of the overall equipment: agricultural organic waste enters the filter cylinder 2 through the top feed hopper 7. The start motor 6 drives the central rod 3 to rotate, which in turn drives the spiral plate 4 to rotate, causing the waste to move upwards under the push of the spiral plate 4. During this process, the liquid in the waste flows out through the filter holes 5 and is discharged from the drain pipe 8 at the bottom of the filter cylinder 2, while the solid material remains on the spiral plate 4 and is conveyed upwards. When the solid material is conveyed to the top of the filter cylinder 2, it is discharged from the top discharge pipe 9, achieving the final purpose of solid-liquid separation. When a hard object jams inside the filter cylinder, the motor 6 continues to rotate, and the central shaft drives the connecting rod 11 to generate a certain resistance. When the resistance of the connecting rod 11 exceeds the preset force set by the compression spring 16 on the push block 17, the outer side of the slot 12 pushes the block 14 out of the slot 12 and slides outwards, overcoming the pushing force of the push block 17. At this time, the connecting rod 11 and the connecting sleeve 10 will rotate freely until the operator stops the operation of the motor 6.
[0040] When the preset force of the compression spring 16 on the push block 17 is required, the rotating sleeve 22 is threadedly engaged with the threaded groove 23, thereby causing the rotating sleeve 22 to drive the sliding sleeve 20 to move. The sliding sleeve 20 slides along the sliding groove 21 and drives multiple sets of pressure blocks 15 to slide along the sliding hole 13. The movement of the multiple sets of pressure blocks 15 compresses the multiple sets of compression springs 16, thereby increasing the pushing force of the compression spring 16 on the push block 17 and increasing the locking force of the push block 17 on the locking block 14, and vice versa.
[0041] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
