Description

Technical Field

[0001] The utility model relates to the field of granulation devices, in particular to a granulation device for contaminated cultivated land soil passivators. Background Technique

[0002] Soil passivators refer to chemical substances used to improve or reduce the toxicity or activity of harmful substances in contaminated soil. They reduce the harm to plants, soil organisms, and groundwater by adsorbing, binding, or transforming harmful substances. Common soil passivators include lime, sulfuric acid, calcium hydroxide, iron oxide, activated carbon, etc.

[0003] A passivator granulator is a device used to convert powdered passivator raw materials into granular finished products. When treating contaminated soil or waste, passivators usually need to be applied in granular form to better mix with the soil or waste and play their role.

[0004] After retrieval, Chinese Patent Publication No.: CN216856628U discloses a granulation device for contaminated cultivated land soil passivators, including a granulation cylinder. There is a feed inlet above one end of the granulation cylinder. A spiral extrusion auger is arranged inside the granulation cylinder. A die section is installed at the front end of the granulation cylinder. A die plate is arranged on one side where the die section is connected to the granulation cylinder. A discharge port is arranged below the die section. A cutter mechanism is installed at the front end of the die section. The two ends of the die section are respectively fixedly connected to the cutter mechanism and the end of the granulation cylinder through flange plates. Connecting the die section to the granulation cylinder through flange plates facilitates the disassembly and assembly of the die section. Different die sections with different aperture sizes on the die plate can be replaced according to the granulation requirements. The passivator particles cut by the cutter fall into the internal space of the die section, playing a buffering role. Then the particles are discharged through the discharge port, avoiding the direct dropping of product particles into the collection device and causing splitting and damage, and ensuring the integrity of the passivator particles.

[0005] Although the above device connects the die to the granulation cylinder by setting flange plates, enabling the device to replace dies with different apertures according to actual needs, since multiple bolts are required to connect the flange plates to the granulation cylinder, it takes a lot of time to loosen and tighten multiple bolts repeatedly when replacing the die, which is not very practical. Therefore, a granulation device for contaminated cultivated land soil passivators is proposed to solve the above problems. Content of the Utility Model
