The speed for having added it to update so that waste and old circuit board is more and more.In waste and old circuit board plate sill containing copper, tin, gold,
The toxic organic matter such as the valuable metals such as silver and halogenated fire-retardants, if it is not processed or dealt with improperly, waste of resource
Meanwhile serious pollution can be produced to environment.
Top-blown bath smelting furnace processing waste and old printed circuit board recovery valuable metal technology is that United Nations Environment Programme pushes away
Recommend the advanced and sophisticated technology of use.The feed way of the waste and old circuit board of top blow smelting stove processing at present is adopted as top-feed, is added
Material mouth is located at smelting furnace furnace roof.Circuit board particle adds from top filling mouth during production, is fallen by self gravitation and enters molten bath.This
Kind feed way is easy to operate, but problems with actual moving process be present：
（1）It is negative pressure that stove is interior when top blow smelting stove produces, and inner flue gas of the stove moves upwards, and flue gas flow rate is big.Material is from top
Adding in dropping process, the circuit board of lighter weight is introduced into molten bath and burnt in upper furnace by flue gas interference is risen in stove,
Organic compound combustion liberated heat in circuit board is caused not concentrate on molten bath, heat loss is larger.
（2）Material adds part lightweight circuit board in dropping process from top and has not enough time to completely burned i.e. by flue gas band
Walk, float to bagroom and assemble with flue gas, uncombusted circuit board Mars easily causes cloth bag scaling loss, influences normally to produce.
（3）Because partial circuit plate does not burn fully in high-temperature region during top-feed, the harmful substances such as bioxin are added
Generation probability, pressure is brought to environmental protection.
Utility model content
The purpose of this utility model there is provided a kind of top blow smelting furnace feeder for handling waste and old circuit board, to solve
Existing feeding device can not make circuit board fully be burnt completely into molten bath, the problem of causing to produce unstable and environmental pollution.
Technical solutions of the utility model are as follows：A kind of top blow smelting furnace feeder for handling waste and old circuit board, its feature
It is：The device is located at the side of top blow smelting furnace body, its buffer bin for including being sequentially connected, regulating valve, passage, unloads
Material valve and push rod, the bottom of the push rod are located at the top in molten bath area.
Further, the push rod is obliquely installed, and its angle between smelting furnace body of heater is 30 DEG C -60 DEG C.
Further, the vane thickness of rotor is 1.0-2.5mm in the discharge valve.
Further, connected between the buffer bin, regulating valve, passage, discharge valve and push rod using flange.
Further, the blade of rotor is stainless steel blade in the discharge valve.
Further, the push rod and discharge valve are high temperature resistant material.
The utility model feeding device can be continuous, uniformly, circuit board particle stably is added into top blow smelting stove high temperature
In molten bath, circuit board is fully burnt, avoid circuit board from top filling when by flue gas interference be unable to completely burned and produce
A series of productions are unstable and safety and environmental protection problem.
The utility model has advantages below：
1st, the feeding device is located at top blow smelting furnace body side, and molten bath area top can be direct by waste and old circuit board particle
Push the air line distance for into furnace high-temperature molten bath, shortening material and molten bath, avoid from top filling when partial circuit plate under
Failed to enter molten bath by flue gas interference during falling, the heat loss caused by upper furnace burning.
2nd, circuit board fully enters high temperature molten bath, and burning liberated heat concentrates on molten bath area, and heat utilization rate is high, more
Energy-conservation.
3rd, avoid the imperfect combustion lightweight circuit board Mars in part and floatd with flue gas and cause cloth bag scaling loss to dust-precipitator, protect
The steady and continuous of production is demonstrate,proved.
4th, the blade on feeding device discharging valve rotor is stainless steel, and thickness is small, flexible strong, when meeting bulk materials
Blade automatic bending in rotor rotation process, prevents from getting stuck.
5th, feeding device charging stable and uniform, automaticity is high, and charging process is easily controllable.
