In the factory covers an area of 150 acres of open space, piles of waste household appliances are neatly sorted and placed; In the workshop with the roar of the machine, workers wearing hard hats are operating the equipment enthusiastically, giving a new life to a set of waste appliances… “The factory can disassemble 2 million used household appliances and recycle 30,000 tons of new materials every year.” Li Shiliang, general manager of Haier Zhijia recycling interconnection factory, told China Securities Journal.

In April this year, after The State Council issued the “Action Plan to promote large-scale equipment renewal and replace old consumer goods with new products”, how to speed up the construction of home appliance recycling and recycling system and open up the “blocking point” of “replacing old appliances with new” has become a hot topic in the industry. Recently, the reporter of China Securities Journal conducted a field survey of the country’s first recycling interconnection factory – Haier Zhijia recycling interconnection factory, and explored Haier Zhijia’s practice of comprehensively building the intelligent manufacturing ability of integrated production of household appliances recycling.

In the busy Haier Zhijia recycling interconnecting factory workshop, the China Securities Journal reporter saw that a recycled waste refrigerator, after a pre-treatment process, enters the customized automatic dismantling line body, through multiple processes such as biaxial shredding, vertical crushing, and multistage sorting, the mixed iron is electromagnetic suction, plastic is blown out by a strong fan, foam is compressed and packaged… In this way, a refrigerator finally ended its life.

“But this is not the end, the old refrigerator will come back to life here.” Haier Zhijia recycling interconnection factory dismantling workshop manager Wang Tingjun told the China Securities Journal reporter, “For example, iron, copper, aluminum will enter the corresponding factory, to achieve 100% recycling; After the plastic is cleaned and granulated, it can be reused in the interior and exterior decoration of automobiles and daily chemical home and office supplies; After modification and regeneration, the foam can be made into building panels, plastic racetracks, etc.”

“We have participated in the household appliance recycling target responsibility system action for two consecutive years and exceeded the recycling target, and nearly 10 million used household appliances were recycled through all channels, and the amount of declaration and recycling ranked first among the participating household appliance manufacturers.” Li Shiliang told the China Securities Journal reporter, “At present, the company has fully built the integrated production and intelligent manufacturing capacity of household appliances recycling, can disassemble 2 million used household appliances per year, recycle new materials and renewable 30,000 tons, and through the use of renewable energy such as photovoltaic and a number of green environmental protection technology innovation, actively create a carbon-neutral demonstration factory, which can reduce carbon by about 17,000 tons per year.” That’s about 1.55 million trees.”

In April this year, after The State Council issued the “Action Plan for Promoting large-scale equipment Renewal and replacing old consumer goods with new ones”, a series of specific measures have recently been introduced around the country to vigorously promote the “replacement of old appliances with new ones”. As a pioneer of recycling in the domestic household appliance industry, Haier Zhijia uses the “Internet + recycling” innovation model to build the country’s first recycling interconnected factory in Qingdao Laixi, which has aroused high attention from the market.

“‘ Sea Whale Green Recycling ‘is one of our’ Internet + recycling ‘innovation models.” Li Shiliang said that relying on nearly 32,000 offline stores and more than 100,000 service personnel, Haier Zhijia innovates the “five-network integration” recycling model, and builds a fifth network, that is, home appliance recycling network, covering more than 2,800 districts and counties across the country, which SA168-3BSE003389R1 can reach every community and village.

The practice of Haier Zhijia recycling interconnected factory has accumulated a lot of successful experience for how to recycle and reuse used household appliances to better promote the “old for new” of household appliances.

For example, at the dismantling end, Haier Zhijia recycling connected factory has laid out six customized intelligent production lines, independently developed the industry’s first large-capacity refrigerator environmental crushing system, the first open high-precision sorting system, and realized the automatic dismantling from parts to materials through digital interconnection. “The automation level is 20% higher than that of the industry, and the refined dismantling is 30% higher than that of the industry.” Li Shiliang said.

At the same time, in order to ensure the safety and standardized dismantling of waste household appliances, Haier Zhijia recycling interconnected factory has added safety protection devices to the shredder equipment of the refrigerator dismantling production line, and set up flame detectors, combustible gas monitoring, fire and flashproof valves, linkage spray devices, safety linkage doors, etc., to achieve the safety improvement and upgrading of the dismantling equipment, and to protect the efficient operation of the dismantling production line.

At the regeneration end, the industry is mostly dominated by the degradation cycle. Haier Zhijia recycling interconnection factory introduced high-quality plastic cleaning and sorting production line and high-quality extrusion granulation line, recycled materials through cleaning, sorting, granulation, modification and other dozens of processes, can maximize the solution of black spots, impurities, odor and other problems in recycled materials, the purity of the output of new recycled materials reached 99.9%, the physical property of almost zero attenuation, The performance of recycled material is comparable to that of original new material.
