[0003] Now the most used way to deal with waste paper resources is to make recycled paper. The process of making recycled paper mainly passes through the waste paper pulping process to turn waste paper into usable pulp. The waste paper pulping process mainly includes crushing, purification, screening, and concentration. After several stages, since the waste paper pulp contains a large amount of impurities such as iron particles, stones, sand, etc., it is necessary to filter out these impurities in the pulp. Since the iron particles have a high recovery value, the staff often pass the pulp through the magnetic bar. , using magnetic rods to remove iron particles to achieve the purpose of recycling. When there are many iron particles adsorbed on the surface of the magnetic rods, it is necessary to remove the magnetic rods and then manually scrape off the iron particles. This method not only increases the workload of the staff At the same time, the pulp processing efficiency becomes low

The invention discloses an impurity removal device for iron particles in waste paper pulp, and belongs to the technical field of waste resource utilization. According to the impurity removal device for iron particles in waste paper pulp, paper pulp can be extruded through a second elastic film, so that fine iron particles in the paper pulp are adsorbed on the surface of a packaging film on bulges under the action of magnetic force. Under the condition that many iron particles are accumulated, the bulges are sunken, then the packaging film is driven to be sunken to package the iron particles, and meanwhile, elastic fluff forms a net-shaped structure to seal the iron particles. When many iron particles are accumulated, the first elastic film is influenced by the gravity of the iron particles, a containing cavity can be automatically opened, a luminous ball can remind a worker to move a magnetic block through a handle, the magnetic attraction force borne by the iron particles is weakened, and then the bulges are reset. In the reset process, the packaging film is separated from the bulges, an automatic separation function is achieved, and the worker can recycle the iron particles conveniently.
Description
technical field [0001] The invention relates to the technical field of utilization of waste resources, in particular to a device for removing impurities of iron particles in waste paper pulp. Background technique [0002] In daily life, waste paper is produced every day. If it is not collected and utilized, it will pollute the environment. In order to prevent waste paper from becoming environmental pollution, rational use of waste paper resources is the way out to solve waste paper pollution. [0003] Now the most used way to deal with waste paper resources is to make recycled paper. The process of making recycled paper mainly passes through the waste paper pulping process to turn waste paper into usable pulp. The waste paper pulping process mainly includes crushing, purification, screening, and concentration. After several stages, since the waste paper pulp contains a large amount of impurities such as iron particles, stones, sand, etc., it is necessary to filter out these ...
