Description

Technical Field

[0001] This utility model relates to the field of waste biodegradation technology, and more specifically, it relates to a spray humidification device for waste biodegradation. Background Technology

[0002] In the process of waste biodegradation, it is often necessary to continuously spray and humidify the pile to maintain a suitable moisture environment, thereby promoting the activity of microorganisms and the decomposition rate of organic matter. This need is particularly prominent in high-temperature seasons or dry areas. However, existing spray and humidification devices are mostly limited to local spraying with a small spray range, making it difficult to achieve uniform coverage of the entire degradation site. This results in some areas having sufficient moisture while other areas are affected by insufficient moisture, which affects the biodegradation effect. In addition, there are certain limitations in the structural design of the equipment, the spray pipeline layout is complex, maintenance and debugging are inconvenient, and it is difficult to adapt to treatment sites of different sizes or layouts.

[0003] Another key issue during the spraying process is the need to regulate the water flow rate. The water requirements of the waste pile vary greatly at different decomposition stages. If the spray flow rate cannot be flexibly adjusted, problems such as excessive humidification or insufficient humidity may occur, affecting the overall fermentation efficiency and processing cycle. In existing technologies, spraying devices mostly use fixed water pressure or coarse control, which makes it difficult to achieve precise regulation and cannot make dynamic responses based on real-time environmental parameters such as temperature and humidity, resulting in resource waste and reduced system operating efficiency.

[0012] This utility model is further configured such that the limiting mechanism includes a limiting block, a limiting groove, a return spring, a limiting sleeve, a support rod, a limiting block, a rotating sleeve, a limiting sleeve, a limiting groove, and an unlocking groove.

[0013] The present invention is further configured such that a side plate is fixedly provided on the outer wall of the connecting sleeve, and a pressing block is fixedly provided on the bottom surface of the rotating sleeve. Multiple sets of pressing springs are provided on both the side plate and the pressing block, and each set is connected to a pressing spring.

At the same time, the push spring provides a reliable restoring force, ensuring the accuracy of the limiting sleeve's return to its original position and improving the stability of the overall structure.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a spray humidification device for waste biodegradation, which has the following beneficial effects:

[0017] 1. This device achieves efficient and precise water flow regulation through the combination of a spraying mechanism, an adjustment mechanism, and a limiting mechanism, effectively meeting the water humidification requirements during the biodegradation of waste. The spraying mechanism, through its reasonable structural design, ensures that water is evenly sprayed onto the waste pile, guaranteeing that all areas are adequately moistened, which helps to enhance the activity of microorganisms and the rapid decomposition of organic matter. The motor-driven rotating pipe works in conjunction with the spray pipe to flexibly adjust the spraying angle and range, thereby improving the adaptability of the spraying system and meeting the needs of different degradation sites.

[0018] 2. The adjustment mechanism further enhances the ability to precisely control the spray volume. By rotating the adjustment sleeve to drive the movement of the screw, the mating sleeve and the connecting frame, the elastic deformation of multiple baffles is adjusted, the size of the water flow space is adjusted, and the spray volume of water is precisely controlled. This mechanism can flexibly adjust according to the actual humidity requirements of the waste pile, avoiding the phenomenon of too much or too little water, optimizing the use of resources and improving the efficiency of biodegradation.

[0019] 3. The limiting mechanism, through a series of precise matching structures, ensures the stability and controllability of the adjustment system. When the spray flow needs to be adjusted, the limiting mechanism can effectively release or restore the restriction on the adjusting sleeve, making the adjustment process smoother and more precise. Through the synergistic action of the return spring and the push spring, the limiting mechanism can precisely limit the position of the adjusting sleeve, preventing excessive deviation during the adjustment process, thereby ensuring the high efficiency and stability of the entire spray humidification system during use. This series of designs makes the device more convenient to operate and can provide precise water flow adjustment according to actual needs, providing better environmental support for waste biodegradation.

[0029] Please see Figures 1-5 A spray humidification device for waste biodegradation includes a movable base 1, on which a spray mechanism is mounted. The spray mechanism includes a support frame 2, a motor 3, a flow hole 4, a linkage frame 5, a rotating pipe 6, an adjusting mechanism, a diverter pipe 7, and a spray pipe 8. The support frame 2 is fixed to the top of the movable base 1, the motor 3 is fixed to the bottom surface of the movable base 1, the flow hole 4 is disposed inside the movable base 1, the linkage frame 5 rotates within the flow hole 4, the rotating pipe 6 is fixed to the top surface of the linkage frame 5, and the adjusting mechanism includes a connecting sleeve 9, an adjusting sleeve 10, a mating sleeve 11, a screw 12, a connecting frame 13, and a baffle plate 14. The system includes a support plate 15, a control block 16, a control groove 17, and a limiting mechanism. A connecting sleeve 9 is fixed to the top of the rotating pipe 6. An adjusting sleeve 10 rotates at the top of the connecting sleeve 9. A mating sleeve 11 is fixed to the inner wall of the connecting sleeve 9. A screw 12 is threaded into the mating sleeve 11. A connecting frame 13 is fixed to the bottom of the screw 12. The support plate 15 is provided with multiple sets of fixed components to the inner wall of the connecting sleeve 9. The control block 16 is fixed to the outer wall of multiple sets of support plates 15. The control groove 17 is provided on the outer wall of multiple sets of baffles 14 and is slidably connected to multiple sets of control blocks 16. A diverter pipe 7 is fixed to the top of the adjusting pipe. A nozzle 8 is fixed to both ends of the diverter pipe 7.

[0030] The present invention is further configured such that an external connecting pipe 18 is fixedly provided at the outer end of the flow hole 4. This structure, through the setting of the external connecting pipe 18, allows water to be stably introduced into the flow hole 4, ensuring a continuous and reliable water supply.

[0031] The present invention is further provided with an anti-slip sleeve 19 fixedly provided on the outer wall of the adjusting sleeve 10. The anti-slip sleeve 19 is a rubber sleeve with anti-slip protrusions on its outer wall. The anti-slip sleeve 19 provides good friction, and with the adjusting sleeve 10, it is not easy to slip during adjustment, thereby enhancing the stability and comfort of operation.

[0032] The present invention is further configured such that a slider 20 is fixedly provided on the outer wall of the connecting frame 13, and multiple sets of sliders 20 are provided. A groove 21 is provided on the inner wall of the connecting sleeve 9, and multiple sets of grooves 21 are provided and slidably connected to multiple sets of sliders 20 respectively. Through the cooperation of sliders 20 and grooves 21, the connecting frame 13 has a guiding function during movement, improving the stability and durability of the overall structure.

[0033] The present invention is further configured such that all sets of baffles 14 are elastic plates. The elastic baffles 14 can deform under the action of water flow pressure, thereby adjusting the water flow area and improving the flexibility and precision of spray adjustment.

[0034] In this embodiment, during use, the external pipe 18 is connected to an external water supply pipe, and water is delivered to the flow hole 4. It is then delivered to the diversion pipe 7 via the rotating pipe 6 and sprayed out through two sets of sprinklers. The motor 3 is started, driving the linkage frame 5 to rotate. The linkage frame 5 drives the rotating pipe 6 to rotate, which in turn drives the two sets of spray pipes 8 to rotate and spray. When the spray volume needs adjustment, the rotating sleeve 28 is rotated, compressing the compression spring 34 through multiple sets of compression blocks 33. This causes the limiting sleeve 29 to rotate and moves multiple sets of unlocking slots 31 below the limiting block 27, releasing the contact between the limiting block 27 and the limiting sleeve 29. This pushes the limiting sleeve 25 to release the contact between the multiple sets of limiting blocks 22 and inserts the support rod 26 into the unlocking slot 31. Multiple sets of compression springs 34 reset and push the rotating sleeve 28 to rotate, causing multiple sets of support rods 26 to slide into the limiting groove 30. This causes multiple sets of abutting blocks to abut against the bottom surface of the limiting sleeve 29 and compress the push spring 37, limiting the limiting sleeve 25. Multiple sets of reset springs 24 pull the limiting block 22 away from the limiting groove 23, releasing the restriction on the adjusting sleeve 10. Then, the adjusting sleeve 10 is rotated to drive the mating sleeve 11 to rotate so that it is threadedly engaged with the screw 12. The screw 12 drives the connecting frame 13 to move, while multiple sets of control grooves 17 slide to connect with the control block 16, thereby controlling the elastic deformation of multiple sets of baffles 14 and adjusting the water flow space between multiple sets of baffles 14, thereby adjusting the spray volume of water.

[0035] Please see Figures 4-5As one implementation of the limiting mechanism: the limiting mechanism includes a limiting block 22, a limiting groove 23, a return spring 24, a limiting sleeve 25, a support rod 26, a limiting block 27, a rotating sleeve 28, a limiting sleeve 29, a limiting groove 30, and an unlocking groove 31. The limiting block 27 is provided with multiple sets that slide on the outer wall of the adjusting sleeve 10. The limiting groove 23 is provided with multiple sets that are distributed on the outer wall of the connecting sleeve 9. The return spring 24 is connected to the top of the multiple sets of limiting blocks 22 and its bottom end is fixedly connected to the outer wall of the adjusting sleeve 10. The limiting sleeve 25 slides on the outer wall of the connecting sleeve 9. The rotating sleeve 28 rotates on the outer wall of the connecting sleeve 9. The limiting sleeve 29 is fixed on the top surface of the rotating sleeve 28. The limiting groove 30 is provided with multiple sets that are distributed on the limiting sleeve 29. The unlocking groove 31 is provided at one end of the multiple sets of limiting grooves 30.

[0036] The present invention is further configured such that a side plate 32 is fixedly provided on the outer wall of the connecting sleeve 9, and a pressing block 33 is fixedly provided on the bottom surface of the rotating sleeve 28. Multiple sets of pressing springs 34 are provided on both the side plate 32 and the pressing block 33, and each set is connected to a pressing spring 34. This structure connects the side plate 32 and the pressing block 33 through the pressing springs 34, providing effective support when the rotating sleeve 28 rotates, thus improving the smoothness and precise control of the adjustment process.

[0037] The present invention is further configured such that a guide plate 35 is provided on the inner side of the limiting sleeve 25, and multiple sets of guide plates 35 are provided; a guide groove 36 is provided on the outer wall of the connecting sleeve 9, and multiple sets of guide grooves 36 are provided and slidably connected to multiple sets of guide blocks respectively; a push spring 37 is fixedly provided on the bottom surface of the limiting sleeve 25, and multiple sets of push springs 37 are provided. The sliding cooperation between the guide plate 35 and the guide groove 36 can ensure that the limiting sleeve 25 moves smoothly along the set path, and the push spring 37 provides a restoring force to ensure that the adjusted component can quickly and accurately return to its original position, thereby improving the reliability of the limiting process.

[0038] More specifically, rotating the rotating sleeve 28 causes multiple sets of support rods 26 to slide into the unlocking groove 31. Multiple sets of push springs 37 push the limiting sleeve 25 to slide along the guide groove 36 through the guide plate 35, so that the inner wall of the limiting sleeve 25 abuts against the top of multiple sets of limiting blocks 22 and squeezes the reset spring 24. The bottom of the multiple sets of limiting blocks 22 is engaged in the limiting groove 23 to fix the adjusting sleeve 10.

[0039] In summary, during use or operation of the overall equipment: When in use, connect the external pipe 18 to the external water supply pipe and deliver water to the flow hole 4. Water is then delivered through the rotating pipe 6 to the branch pipe 7 and sprayed out through two sets of sprinklers. Start the motor 3 to drive the linkage frame 5 to rotate, which in turn drives the rotating pipe 6 to rotate, which in turn drives the two sets of spray pipes 8 to rotate and spray. When it is necessary to adjust the spray volume, rotate the rotating sleeve 28 to compress the compression spring 34 through multiple sets of compression blocks 33, causing the limiting sleeve 29 to rotate and moving multiple sets of unlocking slots 31 below the limiting block 27. This releases the contact between the limiting block 27 and the limiting sleeve 29, pushes the limiting sleeve 25 to release the contact between the multiple sets of limiting blocks 22, and inserts the support rod 26 into the unlocking slot 31. Inside, multiple sets of compression springs 34 reset and push the rotating sleeve 28 to rotate, causing multiple sets of support rods 26 to slide into the limiting groove 30. This causes multiple sets of abutting blocks to abut against the bottom surface of the limiting sleeve 29 and compress the push spring 37, limiting the limiting sleeve 25. Multiple sets of reset springs 24 pull the limiting block 22 away from the limiting groove 23, releasing the restriction on the adjusting sleeve 10. Then, the adjusting sleeve 10 is rotated to drive the mating sleeve 11 to rotate so that it is threadedly engaged with the screw 12. The screw 12 drives the connecting frame 13 to move, while multiple sets of control grooves 17 slide to connect with the control block 16, thereby controlling the elastic deformation of multiple sets of baffles 14 and adjusting the water flow space between multiple sets of baffles 14, thereby adjusting the spray volume of water.

[0040] Rotating the rotating sleeve 28 causes multiple sets of support rods 26 to slide into the unlocking groove 31. Multiple sets of push springs 37 push the limiting sleeve 25 to slide along the guide groove 36 through the guide plate 35, so that the inner wall of the limiting sleeve 25 abuts against the top of multiple sets of limiting blocks 22 and squeezes the reset spring 24. The bottom of the multiple sets of limiting blocks 22 is engaged in the limiting groove 23 to fix the adjusting sleeve 10.

For all the fixed connections mentioned above, welding is preferred.
