5results about How to "Increase the screening area" patented technology

This invention relates to the field of lithium battery recycling technology, specifically to a solid hazardous waste treatment device. The device includes a frame and a screening mechanism. A material conveying mechanism and a guide plate are mounted on the frame, with the guide plate positioned above the conveying mechanism. The screening mechanism includes a rotating disk and a notched annular magnet. The rotating disk is rotatably mounted on the frame, with its end face abutting the guide plate. The annular magnet is disposed inside the rotating disk and can rotate relative to it. When solid hazardous waste passes through the rotating disk, magnetic substances are adsorbed onto it. When the rotating disk rotates to the notch of the annular magnet, the magnetic substances fall onto the guide plate and move to the recycling area. By placing the notched annular magnet inside the rotating disk, the disk can continuously adsorb magnetic substances, reducing the possibility of magnetic substances remaining in the solid hazardous waste and improving the recycling efficiency of magnetic substances.

The utility model belongs to the technical field of capsule conveying, and relates to a pneumatic soft capsule conveying device which comprises a feeding hopper arranged on a supporting frame, the feeding hopper is communicated with a vibration screening assembly, the vibration screening assembly and a pneumatic conveying system are installed in the supporting frame, the vibration screening assembly is respectively communicated with a material guiding slope and a circulation groove, and the circulation groove is communicated with a waste box. A discharging pipe is arranged at the lowest point of the material guiding slope, the pneumatic conveying system is communicated with the circulating groove and the discharging pipe, and a discharging roller is arranged in the discharging pipe. The soft capsules are screened through the vibration screening assembly, wizened and shrunk soft capsules are separated from normal soft capsules, the number of unqualified products in follow-up treatment is reduced, the time needed by manual sorting is shortened, the unqualified soft capsules and the normal soft capsules are pneumatically conveyed through the pneumatic conveying system, and the sorting efficiency is improved. The accumulation of waste materials in a production field is avoided, the cleanliness of the production environment is kept, and meanwhile, the damage risk of normal soft capsules in the conveying process is also reduced.

This invention provides a device and method for separating tobacco scraps and recovering tobacco shreds in the cigarette manufacturing process. The tobacco scraps are fed into a primary vibrating screen via an elevator. "Hard, piercing" scraps are captured by an orthogonal curved screen plate and cylindrical screening holes with alternating dot matrix, separating tobacco dust and scraps with a diameter less than d1. The remaining material is fed into a secondary vibrating screen, where curved guide strips, a size-controlled screen plate, screening holes, separation holes, and a separation surface control the separation of hard scraps with a length greater than d2 and poor plasticity. Flexible tobacco shreds pass sequentially through the screening holes, separation holes, and separation surface, and are finally fed into a tobacco collection box. This invention provides high loosening force, screening efficiency, and low breakage rate for tobacco scraps, and accurately separates scraps from tobacco scraps, improving the recovery rate and quality of tobacco shreds.
