Description

Technical Field

[0001] This utility model belongs to the field of crushing device technology, and in particular relates to a crushing and processing device for hazardous waste management. Background Technology

[0002] Hazardous waste refers to solid waste that is listed in the National Hazardous Waste List or identified as having hazardous characteristics according to the national hazardous waste identification standards and methods. It not only damages the ecological environment and affects human health, but also hinders the sustainable development of society. Therefore, it is necessary to use various treatment methods to treat hazardous waste in order to reduce its harmful effects. The main treatment methods include resource utilization, incineration, solidification, stabilization and landfill. In the treatment process, hazardous waste must first be crushed.

[0003] To address this, Chinese Patent No. CN220780548U discloses a hazardous waste crushing and treatment device. The crushing chamber has a disinfection and dust suppression crushing mechanism in the middle, a filtration and separation mechanism at the bottom, and a drainage filtration mechanism on the side wall of the bottom. By incorporating the crushing chamber, the disinfection and dust suppression crushing mechanism, the filtration and separation mechanism, and the drainage filtration mechanism, during operation, two gears mesh to cause relative movement of the two crushing shafts. At this time, the two crushing rollers crush the hazardous waste. The disinfection and dust suppression crushing mechanism sprays disinfectant onto the hazardous waste while it is being crushed, and the filtration and separation mechanism performs solid-liquid separation on the crushed hazardous waste, thus improving the safety of hazardous waste crushing.

[0004] However, the above-mentioned device directly feeds hazardous waste into the crushing roller for crushing. If the waste is long or large, it is very easy for it to get tangled or stuck in the crushing roller, which requires a long crushing time and downtime for repairs, thus affecting the efficiency of the crushing process.

It has the advantages of automatically discharging hazardous waste that has undergone hammer crushing into the crushing roller for further crushing, effectively avoiding the phenomenon of entanglement and jamming on the crushing roller, and facilitating the scraping and cleaning of the material adhering to the hammer assembly, ensuring the quality of hammer crushing, thereby effectively improving the crushing and processing efficiency. It solves the problem in the prior art that for long and large waste, it is very easy to entangle or jam the crushing roller, requiring a long crushing time and downtime for repair, which easily affects the crushing and processing efficiency.

[0006] This utility model is implemented as follows: a crushing and processing device for hazardous waste management includes a base, a crushing box fixedly connected to the base, a scraper assembly fixedly installed on one side of the crushing box, a receiving plate slidably passing through the middle of the crushing box, and a hammer assembly and a crushing assembly respectively installed inside the crushing box above and below the receiving plate.

[0047] The working principle of this utility model:

[0048] In operation, hazardous waste is fed into the crushing chamber 2 through the feed hopper 201 and falls onto the receiving plate 6. The stepper motor 502 is started, driving the rotating rod 501 to rotate forward and backward at a certain angle. This causes the hammer rod 4 and hammer blade 401 to repeatedly hammer and crush the hazardous waste on the receiving plate 6, cutting it off and achieving pre-treatment of large-sized hazardous waste. Then, the rotating rod 501 drives the hammer rod 4 and hammer blade 401 to move towards the plastic brush strip 301 and slide into it, thus impacting the hammer rod. 4. The attached plastic on the hammer blade 401 is scraped and cleaned, and falls into the collection trough 101 below for collection. At the same time, the half-tooth rotating plate drives the toothed part to mesh with the rack 603 of the extension plate 604, which in turn drives the receiving plate 6 to slide to the right, thereby moving the discharge port 601 into the interior of the crushing box 2. This allows the hazardous waste after being hammered to be automatically guided into the crushing roller 7 through the discharge port 601. The two crushing rollers 7 move relative to each other to carry out the crushing work, avoiding the entanglement and jamming of the crushing rollers 7, and effectively improving the crushing efficiency.
