Description
Technical field
The utility model relates to handle, especially relates to the handle on the etching solution recovery system that the convenient operation personnel firmly grasp, and belongs to the environmental protection equipment field.
Background technology
Improvements along with electron trade, China's wiring board industry development is also broad-based recovery thereupon, point out according to " 2009-2012 Chinese printing circuit-board industry developing foreground forecast analysis report ", China will become PCB industrial base the biggest in the world in recent years, account at present about 30% of world market.Simultaneously, the Suining, Sichuan has been " southwestern circuit card (PCB) the industry manufacture base " that country examines at present, the PCB industry giants such as two places, Chongqing of Sichuan Founder Electronic, Foxconn's electronics enter, and coastal a large amount of circuit board plant is moved to the interior, and the PCB industry will welcome huge business opportunity.
According to the statistics of Chinese wiring board industry, there is family more than 4,000 in China at present wiring board producer, and the less than 1.5% of etching solution recycling system has been installed, and very large market outlook are arranged.If the online circulating technology of printed wiring board etching solution can be promoted in whole PCB industry, then annual recyclable copper is more than 60 ten thousand tons, 5000000 tons of reuse regeneration etching solutions, and direct economic benefit is more than 40,000,000,000 yuan; 100-1,500,000 tons of etching work procedure ammonium chloride usage quantitys, ten thousand tons of ammonia usage quantity 200-250 can be reduced every year, PCB enterprise etching production line production cost can be significantly reduced; Can reduce more than 200 ten thousand tons of ammonia nitrogen dischargings, 4000 tons of COD dischargings every year, significantly reduce the waste discharge amount of PCB enterprise, thereby have good society, environment and economy benefit.After successfully opening up the domestic market and obtaining certain experiences, further Opening International Market, the low and strongly professional advantage by means of the domestic-developed cost, it is very possible that product is squeezed into the international market.
In the printed circuit board production process, etching is a very important process procedure, and because must use a large amount of etching solutions, it has also become an operation that produces the severe contamination source.To this domestic traditional governance approach be: alkaline etching liquid is reclaimed to discuss by Hazardous wastes and carries out resource utilization recovery copper at present, produce the copper sulfate product, its treating processes need to consume a large amount of reagent, produce a large amount of washess, or the product purity that obtains is inadequate, and can not the Direct Regeneration etching reagent, economic benefit is low, can not reclaim the etching solution of inefficacy, environment is had certain impact, and cause the energy consumption of transportation and cost to increase.This has not only caused the significant wastage (in per 1000 liters of alkaline etching liquids except cupric, also having the ammonium chloride more than 240 kilograms, about 30 kilograms the chemical substances such as liquefied ammonia) of resource, and waste liquid do not obtain real radical cure, has formed the transfer of source of pollution.Because etching solution is toxic substance, need to seal, sealing all is to adopt large-scale and thick and heavy sheet glass to seal, the smooth surface of sheet glass, it is very inconvenient when operator carry, traditional grip structure is complicated, and volume is large, Heavy Weight, increased the weight of sealing cover, and profile all is that profile is arranged, and operator in the situation that hold for a long time take, and will cause wearing and tearing to palm, when operator firmly grasp with finger, because the impetus of finger is smaller, under the effect of sweat, easily skids.
The utility model content
The purpose of this utility model is to overcome the shortcoming and defect of above-mentioned prior art, handle on the etching solution recovery system that the convenient operation personnel firmly grasp is provided, and this grip structure is simple, and volume is little, lightweight, low cost of manufacture, by being connected of handle and sheet glass, the handled easily personnel are to the carrying of sheet glass, the efficient of carrying is high and laborsaving, simultaneously sealing plate has also guaranteed the sealing to device interior, and what groove can handled easily personnel finger holds with a firm grip, avoids the phenomenon that occurs skidding.
The purpose of this utility model is achieved through the following technical solutions: the handle on the etching solution recovery system that the convenient operation personnel firmly grasp, comprise that being holding of cylinder shape takes parts, described holding by the parts bending is circular-arc, radian is 140 ° to 150 °, hold and take the outer wall indent of parts to form several annular grooves, described two ends of holding by parts are provided with permanent seat, and permanent seat and hold by parts and be connected to one-piece construction, permanent seat is provided with Connection Block, and the medullary ray of Connection Block and plummet are on same straight line.
Further, the quantity of described groove is four.
Further, the described crooked radian of holding by parts is 145 °.
Further, described Connection Block is provided with threaded column away from an end of permanent seat, and is sheathed with nut on the outer wall of threaded column.
Further, be sheathed with sealing plate on the outer wall of described threaded column, and described sealing plate is arranged between Connection Block and the nut, sealing plate size greater than the size of Connection Block.
Further, described nut near sealing plate be provided with contactless ring on the end face, contactless ring and nut are connected to one-piece construction, the medullary ray of contactless ring and the medullary ray of nut are on same straight line, and the internal diameter of contactless ring is consistent with the internal diameter of nut, and the external diameter of contactless ring is greater than the external diameter of nut.
Further, described sealing plate adopts elastomeric material to make.
In sum, the beneficial effects of the utility model are: this grip structure is simple, volume is little, and is lightweight, low cost of manufacture, by being connected of handle and sheet glass, the handled easily personnel are to the carrying of sheet glass, and the efficient of carrying is high and laborsaving, and sealing plate has also guaranteed the sealing to device interior simultaneously, groove can the handled easily personnel the holding with a firm grip of finger, avoid the phenomenon that occurs skidding.
