Description

Screening machine

[technical field]

The utility model is about a kind of screening machine, refer to especially a kind of be applied to discarded cable, electric wire and pulverize after, use the dry type separate mode to reclaim the screening machine design of copper metal.

[background technology]

In early days the copper of valency metal is arranged in discarded cable, the electric wire in order to reclaim, people utilize combustion system to remove the plastic insulating layer of copper cash appearance lining mostly, owing to can cause air pollution after the plastic insulating layer burning and produce the harmful human body of poisonous dioxin (dioxin), nowadays, people mostly adopt the pulverizing water-washing method that meets environmental protection to recycle this discarded cable, electric wire.

This pulverizes the embodiment of WATER-WASHING METHOD, main system uses pulverizer with waste electric wire, cable is ground into tiny block, and the copper cash in the electric wire is separated under pulverization with plastic layer, continue and carry out the screening detached job of copper metal and plastics with the rinsing type vibrating screener, wherein this rinsing type vibrating screener mainly is to utilize motor eccentric drive mode to drive its rinsing bowl to produce reciprocal vibration, pulverize the back copper cash, the mixture of plastics is poured into from the rinsing bowl middle section, under the effect of rinsing bowl double vibrations, and utilize copper cash than great, more be not subject to water currents, in vibration, move toward eminence, and plastics are little because of proportion, be subject to water currents, can flow to the rinsing bowl lower with current, by this, make this rinsing type vibrating screener be able to be screened with plastics and separate, and then reclaim the recycling valency copper metal that has mixing together copper metal.

Only, though the aforementioned pulverizing WATER-WASHING METHOD of commonly using can provide a kind of processing cable waste of environmental protection, mode that electric wire reclaims the copper metal of meeting, so it uses in the operation in reality and has following problem, wherein:

1, it is when utilizing rinsing type vibrating screener separating copper metal and plastics, because of the copper metal is easy to oxidation after soaking water, and poor quality, so that can reduce the price of this recoverys copper metal, reduce recycling the due profit of dealer;

2, this rinsing type vibrating screener is when operation, because of being takes two-way separate mode, because normal the retention has unsegregated electric wire fritter in the mixture after waste electric wire is pulverized, in the process of separating treatment, this unsegregated electric wire fritter can be doped in copper metal or plastics material, so can't reach the optimum state of effective separating treatment.

3, this rinsing type vibrating screener is when using, and because of copper metal and plastic material all are soaked in the water, because of containing the copper metal, as if not installing wastewater treatment additional, has the facts of water pollution in the water.

[utility model content]

The main purpose of the utility model is to provide a kind of screening machine, make it in the process of separating recycling, can effectively avoid copper metal immersion oxidation to cause to reclaim the problem of copper price reduction, and can reach optimized separating effect after can allowing waste electric wire pulverize.

Take off purpose for before reaching, the screening machine design that the utility model proposed mainly lies in installing one mobilizable oblique screen cloth on the board, the vibrating device of one group of tool motor of installing in the board, make the horizontal direction double vibrations in order to drive screen cloth, establish air-blast device in addition with respect to the screen cloth below, screen cloth towards the top blows from board in order to produce air-flow, pours in the screen cloth and isolates wherein copper metal in order to the mixture that waste electric wire is pulverized, and constitutes one group of dry type screening and separating machine tool by this.

The utility model designs via aforementioned structure, can produce following advantage after implementing, wherein:

1, avoid copper metal immersion oxidation: the mixture that the utility model system pulverizes waste electric wire is taked dry type separating treatment mode, the copper metal is effectively separated with the plastic insulation material, and allow the copper metal not contact and oxidation with water, keep the primary colors of copper metal, so allow the price that reclaims copper improve.

2, reach optimal separating efficiency after allowing waste electric wire pulverize: the utility model system utilizes askew planar screen cloth to cooperate the design of vibrating device and air-blast device airflow blow, the mixture that waste electric wire is pulverized can fast and effeciently separate the copper metal, also can separate recovery in the thin piece of the pulverizing incomplete electric wire in back and locate again, so can see through the separation recovering effect that the screening of the utility model dry type reach the best after waste electric wire is pulverized.

3, the problem of water pollution-free: same as above, the designed screening machine system of the utility model takes dry treatment method, and complete non-wastewater discharge in using operating process is so can exempt the problem of environmental pollution by water.
