Description

Technical Field

[0001] This utility model relates to the technical field of organic waste treatment equipment, and in particular to an automated screening and processing device for the resource utilization of biomass waste. Background Technology

[0002] Biomass waste recycling is an important way to achieve "reduction, harmlessness, and resource utilization". By processing biomass waste such as straw, kitchen waste, and garden waste, it can be transformed into renewable resources such as organic fertilizer and biomass fuel. This can not only alleviate the environmental pressure caused by landfill and incineration, but also provide high-quality raw materials for agriculture, energy and other fields. It is of great significance to promoting the development of a circular economy and the construction of ecological civilization.

[0003] Common automated screening and processing devices for biomass waste resource utilization typically consist of a feeding system, a screening system, a conveying system, and a control system. Biomass waste is evenly fed into the device via a conveyor belt, separating waste of different particle sizes. The screened materials are then transported to different processing stages, thereby removing some large impurities and providing relatively pure raw materials for subsequent resource utilization processes such as crushing and fermentation, thus improving the efficiency of biomass waste treatment to a certain extent.

[0004] Currently used equipment has a fixed screen aperture, which is difficult to adapt to biomass waste with complex composition and large particle size differences, resulting in low screening accuracy. Some fine effective materials are mixed with impurities, affecting the quality of subsequent resource utilization. In addition, the screen is easily clogged by fibrous and sticky substances after long-term use, and cleaning and maintenance are inconvenient. It often requires manual cleaning after machine shutdown, which not only increases labor intensity but also reduces the continuous operation efficiency of the equipment. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-6 This utility model provides an embodiment of an automated screening and processing device for the resource utilization of biomass waste, including a screen box 1. The screen box 1 is the main frame of the device, providing a mounting foundation for various components and forming a relatively enclosed screening space to prevent material splashing. Multiple evenly distributed discharge ports 2 are provided at the front of the screen box 1, which are used to discharge screened materials of different particle sizes separately, facilitating subsequent transportation to different processing stages according to category. A feeding hopper 4 is fixedly connected to the top of the screen box 1, which is used for centralized feeding of biomass waste. A maintenance door 3 is hinged to the left side of the screen box 1, allowing access around... The hinge point rotates to open and close the screen. When open, it facilitates maintenance, cleaning, or replacement of internal components such as the screen plate 8. A vibration motor 5 is installed at the rear of the screen box 1. A drive shaft 6 is fixedly connected to the output end of the vibration motor 5. A mounting plate 7 is fixedly connected to the top of the drive shaft 6. The vibration motor 5 serves as the power source, driving the drive shaft 6 to transmit vibration to the mounting plate 7, thereby causing the screen plate 8 to vibrate synchronously. The mounting plate 7 is used to install and fix the screen plate 8. Multiple evenly distributed screen plates 8 are slidably connected to the front of the mounting plate 7. The screen plate 8 is the core component for realizing the screening function. The multiple screen plates 8 are arranged downwards in descending order of aperture size. The installation and maintenance door 3 abuts against the left side of the screen plate 8, which in turn abuts against the inner wall of the screen box 1. The contact between the maintenance door 3 and the inner wall of the screen box 1 limits the movement of the screen plate 8 when the maintenance door 3 is closed. A solid feeding plate 9 is fixedly connected to the bottom front side of the mounting plate 7. The solid feeding plate 9 is used to collect small materials that fall through the bottom screen plate 8. The maintenance door 3 abuts against the left side of the solid feeding plate 9, which abuts against the inner side of the screen box 1. A locking component is provided on the left side inside the mounting plate 7. Multiple evenly distributed discharge plates 10 are fixedly connected to the front side of the screen box 1. The discharge plates 10 are inclined at the outlet... Outside the material outlet 2, the material discharged from the discharge outlet 2 can be guided to fall accurately into the conveyor belt 12, preventing the material from falling outside the device. The left and right sides of the front of the screen box 1 are fixedly connected with baffle plates 11. The left and right sides of the discharge plate 10 abut against the opposite side of the baffle plates 11. The baffle plates 11 can prevent the material from sliding off the sides of the conveyor belt 12 during the conveying process, and play a limiting and guiding role. Multiple evenly distributed conveyor belts 12 are installed on the opposite side of the baffle plates 11. The conveyor belts 12 are used to receive the material conveyed by the discharge plate 10 and transfer it to the subsequent crushing, fermentation and other processing processes to realize automated conveying.

[0035] Reference Figures 4-6 The locking assembly includes a lever 17, which is slidably connected to the left side of the mounting plate 7. The lever 17 is the operating component of the locking assembly; by moving the lever 17, the locking or unlocking state of the screen plate 8 can be controlled. Limiting blocks 18 are fixedly connected to the top and bottom of the lever 17. Multiple vertically distributed limiting grooves 20 are provided on the left side of the interior of the fixing plate 13. The limiting blocks 18 are slidably connected within the limiting grooves 20 and can be embedded within the limiting grooves 20 to limit the sliding direction and distance of the lever 17, preventing the lever 17 from disengaging from its installation position. A fixing rod 16 is fixedly connected to the front side of the lever 17. Multiple evenly distributed fixing holes 15 are provided on the front side of the fixing plate 13. The fixing rod 16 is slidably connected within the fixing holes 15. By inserting the fixing rod 16 into the fixing holes 15, the fixing plate 13 can be fixed to the mounting plate 7, thereby locking the screen plate 8. A spring 19 is fixedly connected to the rear side of the lever 17. The spring 19 has an elastic reset function. When the lever 17 is released, it can push the lever 17 to reset, so that the fixing rod 16 is kept inserted into the fixing hole 15. A fixing plate 13 is fixedly connected to the rear side of the screen plate 8. The fixing plate 13 is fixed to the screen plate 8 as a whole. The screen plate 8 is installed and fixed through the connection between the fixing plate 13 and the mounting plate 7. The mounting plate 7 has multiple evenly distributed fixing grooves 14 on the front side. The fixing plate 13 is slidably connected in the fixing groove 14. The lever 17 is slidably connected in the left side inside the fixing groove 14. The other end of the spring 19 is fixedly connected in the left side inside the fixing groove 14. The fixing groove 14 provides an insertion space for the fixing plate 13, so that the fixing plate 13 can slide along the fixing groove 14, which facilitates the installation and disassembly of the screen plate 8. It also provides installation space for the lever 17 and the spring 19.

[0036] Working principle: After biomass waste enters the screen box 1 through the feeding hopper 4, the vibration motor 5 starts and transmits the vibration to the mounting plate 7 through the transmission shaft 6, which drives the multiple screen plates 8 with the aperture from large to small to vibrate synchronously. Under the action of vibration, the waste moves along the surface of the screen plate 8. Large impurities are intercepted by the upper large aperture screen plate 8, medium-sized particles are separated by the middle screen plate 8 after passing through the upper screen plate 8, and fine particles fall through the lower screen plate 8 into the solid feeding plate 9. Materials of different particle sizes are discharged from the corresponding outlet 2 and guided to the conveyor belt 12 by the feeding plate 10. Under the limiting action of the baffle plate 11, they are transported to the subsequent processing stage. The entire screening process is completed in the closed space of the screen box 1, avoiding material splashing.

[0037] When the screen plate 8 needs to be replaced or cleaned, open the maintenance door 3, move the lever 17 of the locking assembly to pull the fixing rod 16 out of the fixing hole 15 of the fixing plate 13, and at the same time, the limit block 18 slides along the limit groove 20 to release the lock on the screen plate 8. The screen plate 8 can then be pulled out from the fixing groove 14 of the mounting plate 7. After maintenance, reset the screen plate 8, release the lever 17, and the spring 19 pushes the lever 17 to reset, so that the fixing rod 16 is reinserted into the fixing hole 15, thereby quickly fixing the screen plate 8. After closing the maintenance door 3, it and the inner wall of the screen box 1 together form a limit on the screen plate 8 and the solid feeding plate 9, ensuring the stable operation of each component of the device during the vibrating screening process and ensuring continuous processing efficiency.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
