Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of screening devices for municipal solid waste incinerator slag, specifically to an anti-clogging device for the comprehensive utilization of municipal solid waste incinerator slag. Background Technology
[0002] Vibrating screens, also known as three-dimensional vibrating screen filters, utilize the principle of vibration motor excitation to throw materials onto the screen surface and simultaneously propel them forward in a straight line. Combined with a properly matched screen mesh, this achieves the purpose of screening. Currently, most existing vibrating screens used in the primary sorting stage of municipal solid waste incinerators lack anti-clogging devices, easily causing blockages, wasting time, and hindering screening operations. With advancements in science and technology and social development, people have placed higher demands on vibrating screens.
[0003] To address the aforementioned technical problems, existing screening equipment includes an operating chamber containing a vibrating screen. A fixing plate is fixedly installed on the inner wall of the operating chamber, above the vibrating screen. Two symmetrical grooves are formed at the bottom of the fixing plate, within which a slider is slidably mounted, with its bottom extending beyond the groove. An anti-clogging plate is slidably mounted at the bottom of the slider. Rotary shaft grooves are formed on the inner walls of the two grooves on their adjacent sides, housing a rotating shaft. However, when large slag particles are present on the vibrating screen plate, the anti-clogging plate cannot scrape them into the filter holes inside the screen plate, causing them to accumulate and clog the surface. This negatively impacts subsequent screening efficiency and reduces overall work efficiency. Utility Model Content

The anti-blockage recycling mechanism includes an adjustment component and a reset scraping component. The adjustment component includes a fixed frame 3, which is installed inside the screening machine 1 above the vibrating screen plate 2. A reciprocating screw 4 is rotatably connected to the inside of the fixed frame 3, and an adjustment plate 5 is threadedly connected to the outside of the reciprocating screw 4. A sliding groove is opened at the bottom of the inner side of the fixed frame 3. A sliding block 6 is installed at the bottom of the adjustment plate 5 and is slidably connected to the sliding groove. A motor is installed on one side of the screening machine 1. The drive end of the motor extends to the inner side of the fixed frame 3 and is fixedly connected to the reciprocating screw 4. The reset scraping component includes a positioning plate 7, the top of which is fixedly connected to the bottom of the adjustment plate 5. The positioning plate 7 has an "n" shaped cross-section. A scraper 8 is slidably connected to the inner side of the positioning plate 7. Multiple sets of reset springs are arranged between the top of the scraper 8 and the bottom of the inner side of the positioning plate 7. The screen 1 has guide grooves on both sides, and recycling boxes 10 are attached to the guide grooves on both sides of the screen 1 by means of an installation mechanism. The recycling box 10 has an opening on the side that fits into the guide groove, and an observation window 16 is embedded in one side of the recycling box 10. A lifting groove is provided on one side of the recycling box 10 below the observation window 16. When the device is in use, the starting motor drives the reciprocating screw 4 to rotate, which, together with the sliding block 6, the sliding groove and the adjusting plate 5, drives the positioning plate 7 to move back and forth. The scraper 8 contacts the surface of the vibrating screen plate 2 to scrape and send smaller slag into the filter holes, while larger slag is scraped to the inside of the guide grooves on both sides and falls into the recycling box 10 for centralized collection and processing. The structure is simple and the operation is convenient, which further eliminates the possibility of clogging. The scraper 8 will squeeze the reset spring 9 to retract as the vibrating screen plate 2 vibrates up and down, and move in coordination with it, so that the scraper 8 always fits in contact with the surface of the vibrating screen plate 2.
[0023] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the installation mechanism includes a docking assembly and a pull-out assembly. The docking assembly includes multiple sets of top blocks 11, which are arranged and installed at both ends of the top of the recycling box 10. Mounting seats 12 are installed on both sides of the screening machine 1. Each mounting seat 12 has a slot at both ends of its inner side that slides with the top blocks 11. A movable groove is provided inside the mounting seat 12 on one side of the slot, and a movable block 13 is slidably connected inside the movable groove. Springs are installed at both ends of one side of the movable block 13. The pull-out assembly includes multiple sets of pull rods 14, which are slidably connected inside the mounting seat 12. One end of each pull rod 14 is fixedly connected to one side of the movable block 13. A connecting plate is installed at the end of each pull rod 14 extending to the outside of the mounting seat 12. A rotating connection is located at the center of the connecting plate. The device is equipped with a handle 15. The opposite ends of the movable block 13 and the top block 11 are provided with mutually fitting inclined surfaces. The cross-section of the movable block 13 is "T" shaped. By aligning the top block 11 with the slot and pushing it in, the inclined surfaces of the top block 11 and the movable block 13 abut against each other. The movable block 13 compresses the spring to retract. After the top block 11 is fully inserted, the movable block 13 is ejected and abuts against one end of the top block 11 to complete the locking and fixing. The docking installation is relatively quick. Conversely, by pulling the handle 15 in conjunction with the connecting plate, the pull rod 14 and the movable block 13 are moved. The spring is compressed again to retract, and then the top block 11 can be pulled out to complete the disassembly. The structure is simple and easy to operate, making it convenient for workers to disassemble the full recycling box 10 for centralized processing of larger slag.
[0024] The implementation principle of the anti-clogging device for comprehensive utilization of municipal solid waste incineration slag in this application embodiment is as follows: During use, the device can be driven by a starting motor to rotate the reciprocating screw 4, which, in conjunction with the sliding block 6, sliding groove, and adjusting plate 5, drives the positioning plate 7 to move reciprocally. The scraper 8 contacts the surface of the vibrating screen plate 2 to scrape and send smaller slags into the filter holes, while larger slags are scraped to the inner side of the guide grooves on both sides, falling into the recycling box 10 for centralized collection and processing. The simple structure and convenient operation further eliminate the possibility of clogging. Furthermore, the scraper 8 retracts by squeezing the reset spring 9 with the up-and-down vibration amplitude of the vibrating screen plate 2, in conjunction with... The scraper 8 is moved so that it always stays in contact with the surface of the vibrating screen plate 2. After the top block 11 is aligned with the slot and pushed in, the inclined surfaces of the top block 11 and the movable block 13 abut against each other. The movable block 13 compresses the spring and retracts. After the top block 11 is fully inserted, the movable block 13 is ejected and abuts against one end of the top block 11 to complete the snap-fit and fixation. The docking installation is relatively quick. Conversely, pulling the handle 15 in conjunction with the connecting plate drives the pull rod 14 and the movable block 13 to move, compresses the spring again to retract, and then pulls out the top block 11 to complete the disassembly. The structure is simple and the operation is convenient. It is convenient for staff to disassemble the full recycling box 10 so that larger slag can be centrally processed.
