Embodiment Construction
[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0026] A process for dismantling waste electric water heaters, which includes: the disassembled waste electric water heaters are first manually disassembled on the dismantling workbench for small parts on the water heaters, such as mounting brackets, electric heaters, circuit boards, buttons, displays, Inlet and outlet water pipes, etc., and then cut the metal shell with an automatic cutting machine, then put the water heater into the shell tearing machine to peel off the metal shell, manually remove the end caps at both ends of the water heater, and pressurize the polyurethane foam layer from the inner tank , and at the same time realize the volume reduction of the liner; that is, the tearing machine peels off the shell and the polyurethane foam layer, the press machine separates the polyurethane foam layer from the liner, and the bag...

The invention discloses a dismounting process and device for a waste electric water heater. The process comprises the steps that small components on the water heater are dismounted manually on dismounting tables, then a metal shell is cut through an automatic cutting machine, and afterwards the water heater is placed in a shell tearing machine to remove the metal shell; after end covers at the two ends of the water heater are removed manually, a pressure machine is used for pressurization, a polyurethane foaming layer is separated from a liner, and meanwhile volume reduction of the liner is achieved; a production line is provided with air suction covers in the positions of the dismounting tables, the cutting machine, the tearing machine and the pressure machine, and dust removal is conducted through a bag type dust removal system. The waste electric water heater dismounting device mainly comprises the dismounting working tables, a conveying roller line, the automatic cutting machine, the tearing machine, the pressure machine and the bag type dust removal system. By the adoption of the multiple special units, the metal shell, the liner and the polyurethane foaming layer of the electric water heater can be well dismounted; the dismounting process and device for the waste electric water heater have the advantages that the process is unique, the dismounting effect is good, energy consumption is low, the service life of the device is long and the labor intensity of workers is relieved.
Description
technical field [0001] The patent of the present invention relates to a process for dismantling waste electric water heaters and the equipment used, in particular to an efficient and simple dismantling method for waste electric water heaters. Background technique [0002] Waste electric water heaters are household appliances commonly used in human daily life. At present, China has become a big country in the production and consumption of household appliances. my country has entered the peak period of household appliance elimination and scrapping, how to efficiently and easily disassemble waste electric water heaters has become a problem that needs to be solved. [0003] Since waste electric water heaters are composed of metal and non-metal materials, they have good reuse value. The existing waste electric water heaters are directly discarded, and the various materials therein are not effectively decomposed, resulting in waste of resources and pollution to the environment. ...
