Technical field
The invention discloses a kind of discarded printed circuit boards electronic devices and components and dismantle reclaimer automatically, belong to electron wastes application technology as the second resource field.
Background technology
Printed circuit board (PCB) is the basis of electronics industry, is widely used in the electronic and electrical equipments such as computer, communication apparatus, measurement and control instrument instrument, household appliances.Printed circuit board (PCB) is about whole electron wastes about 3%.At present, the average growth rate of world's printed circuit board (PCB) is 8%-9%, and some countries and regions' growth rates of Asia are more up to 20%-30%.At present, the electronic product market total scale of China has reached 1 trillion yuan, the electronics industry output value has occupied the 4th in the world.A large amount of production must cause a large amount of discarding.According to statistics, 80% of whole world electron wastes is exported to the Asia, wherein has 90% to get into China again at this.Contain a large amount of poisonous and harmful substances in the waste and old printed circuit board, as deal with improperly, in case get into environment, can be to environment and the extremely serious harm of human generation.
On the other hand, from the angle of resource, " waste and old printed circuit board " is not " refuse ", but untapped " secondary resource " has very high recycling and be worth.Meanwhile, the non-ferrous metal demand of China increases rapidly, supplies with and exists huge breach, and according to statistics, copper of China 70% and 30% plumbous zinc resource depend on import at present, and along with expanding economy, the breach of non-ferrous metal also can continue to increase.
Therefore, how to carry out the recycling treatment of electron wastes such as waste and old printed circuit board effectively, become the current new problem that China's economy, society and environment sustainable development and China's utilization of the recycling of renewable resources face that is related to.
The resource of waste and old printed circuit board reclaims and starts from 1969 the earliest, and United States Bureau of Mines (USBM) had adopted mechanical method at that time, attempts from the crushed product of discarded military equipment, reclaiming noble metal, and has built up the pilot plant that treating capacity reaches 0.23t/h.After this, along with the attention of the mankind to secondary resource utilization and environmental protection, the resource of electron wastes reclaims research and develops rapidly, comprises technology such as hand disassembly, mechanical treatment, pyrometallurgy, hydrometallurgy, biotechnology metallurgy and electrometallurgy.Each family of the world has all done many researchs and work in this respect, obtains tangible progress and breakthrough.But the normal service life of the electronic devices and components that attach on the discarded printed circuit boards is about 500,000 hours, and the electronic devices and components on the discarded printed circuit boards are merely about 20,000 hours average service time.Therefore; After electronic devices and components dismounting on the discarded printed circuit boards, it is applied to the preparation of new printed circuit board (PCB) again, and directly reclaim various resources and compare from discarded printed circuit boards; Again the electronic devices and components that utilize; Can avoid in its production process producing the consumption of the various resources and the energy, also avoid the environmental pollution that produces in its production process, thereby had extremely considerable social economic environment benefit.
At present, on the discarded printed circuit boards electronic devices and components also be in the starting stage, also do not have the technical scheme of mature and feasible so far.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art scheme, propose a kind of new, efficient is high, energy consumption is low, pollute on the little discarded printed circuit boards electronic devices and components dismantles reclaimer automatically.
A kind of discarded printed circuit boards electronic devices and components are dismantled reclaimer automatically, comprise charging flap valve, continuous progressive intensification chamber, impulse oscillation detaching chamber, four parts of discharging flap valve, and four parts connect as a whole, integral sealing; Said charging flap valve links to each other with continuous progressive intensification chamber, and continuous progressive intensification chamber is connected with pulse vibrations detaching chamber, and pulse vibrations detaching chamber is connected with the discharging flap valve; Between continuous progressive intensification chamber and impulse oscillation detaching chamber, gas separator is set; Continuous progressive intensification is indoor establishes the preheating conveyer belt and the cooling pipe that refluxes, and is provided with exhaust outlet and drain valve; Pulse vibrations detaching chamber is established the netted conveyer belt of high temperature, high temperature discrete pulse winding-up pipe, vibrations separator and vibrations bolter, and is connected to drain valve.
Described equipment, its charging flap valve and discharging flap valve adopt double layer design, seal with assurance equipment.
Described equipment, its continuous progressive intensification chamber adopt superheated steam abandoned printed circuit board to be carried out preheating, the discarded printed circuit boards reverse movement in the flow direction of superheated steam and the continuous progressive intensification chamber on the preheating conveyer belt.
Described equipment, discarded printed circuit boards separate with superheated steam high temperature pulse winding-up vibrations on the netted conveyer belt of high temperature, and screening is after the classification of discharging flap valve is reclaimed, and fusion welding is discharged through the tin soldering liquid outlet.
The present invention is heating source with the superheated steam; And realize that through pulse jet discarded printed circuit boards separates with the vibrations of its electronic devices and components with superheated steam; Adopt hermetically sealed design; Avoided in its electronic devices and components high temperature unloading process of discarded printed circuit boards environment being caused secondary pollution, realized that discarded printed circuit boards separates with the innoxious automatic dismounting of its electronic devices and components.
