Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of separation of waste, household garbage and industrial solid waste, and particularly relates to a magnetic separation device capable of preventing blockage. BACKGROUND

[0002] With the rapid development of society, resources are continuously reduced due to the continuous increase of waste, so it is necessary to recover useful substances and energy from waste by engineering technology to ensure the recycling of resources.

[0003] At present, waste such as waste spinning containing metal and non-metal (having winding characteristics) is generally subjected to magnetic separation by a magnetic separation device in the recycling process to separate the metal and non-metal (having winding characteristics) in the waste. The existing magnetic separation device is generally installed at the discharge end (end) of the conveying line for conveying the waste, and is used to magnetically separate the metal in the waste. The existing magnetic separation device comprises a hopper, a conveying line and a magnetic separation cylinder. The opposite sides and the bottom of the hopper are all open structures. The openings on the opposite sides of the hopper are respectively an inlet and an outlet, and the opening on the bottom of the hopper is a discharge port. The discharge port is isolated from the inlet and the outlet by a partition. The inlet is connected with the discharge end of the conveying line. The magnetic separation cylinder is rotatably arranged on the hopper and drivingly connected with the end of the conveying belt of the conveying line, so that the magnetic separation cylinder rotates with the transmission of the conveying belt. When the waste is conveyed from the beginning to the end of the conveying belt, i.e. the position of the magnetic separation cylinder, the metal in the waste will be attracted by the magnetic induction of the magnetic separation cylinder and be attracted by the magnetic separation cylinder, and the non-metal will be discharged from the outlet. Since the conveying belt is in a circulating transmission state, when the metal attracted by the magnetic separation cylinder is conveyed to the lower part and is not magnetically induced by the magnetic separation cylinder, the metal will be separated from the conveying belt and fall from the position of the discharge port, so as to separate the metal and the non-metal in the waste.

[0004] However, in the process of separating the metal and the non-metal in the waste, some non-metal having winding characteristics may be hung on the partition during discharging from the discharge port, or some non-metal having winding characteristics may be pressed by the metal, so that the non-metal pressed will enter the lower part of the conveying belt with the metal. Thus, the non-metal having winding characteristics will be hung on the partition during falling with the metal, so as to block the discharge port of the metal, and manual intervention is required to ensure the normal operation of the magnetic separation device. SUMMARY

[0005] The present application aims to at least solve one of the problems in the prior art, and provides a magnetic separation hopper capable of preventing non-metal having winding characteristics from blocking the discharge port of the metal when magnetically separating the metal in the waste containing metal and non-metal having winding characteristics.
