Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, illustrate the present invention further, following detailed description of the invention should be understood and be only not used in for illustration of the present invention and limit the scope of the invention.It should be noted that, the word "front", "rear" of use is described below, "left", "right", "up" and "down" refer to direction in accompanying drawing, word " interior " and " outward " refer to the direction towards or away from particular elements geometric center respectively.
As shown in the figure, a kind of polypropylene device for recovering powder of the present invention, comprise water treatment case 3, water is had in described water treatment case 3, the upper cover of described water treatment case 3 is removable cover, air vent 2 and water falling hole 4 is covered with on described, the front end of Fan pipeline 1 is submerged in water by air vent 2, water treatment case 3 side is provided with delivery port 5, delivery port 5 is provided with drainage pipeline 6, drainage pipeline 6 outlet activity connects filter bag 13, the internal layer of described filter bag 13 is polytetrafluoroethylpunched punched felt 14, melt spraying non-woven fabrics 15 is selected in middle level, skin forms for glass fibre and Aramid fibers 16 blending, the bottom of remaining water tank 12 is placed on bottom described filter bag 13, remaining water tank 12 upper opening, water in remaining water tank 12 flows in water treatment case 3 by water pipe 7 from water falling hole 4 by water pump 8, the first control valve 11 is provided with between water pump 8 and remaining water tank 12, water pump 8 other end is communicated with water source, the second control valve 9 is provided with between water pump 8 and water source 10.
During work, the front end of Fan pipeline 1 of the present invention enters in water treatment case 3 by air vent 2, containing portion of water and polypropylene powder in now taken out wind, and temperature is very high, water treatment case 3 is closed, water-fast polypropylene dust can not be allowed everywhere to fly, time one is long, water slowly surplus is just had in water treatment case 3, polypropylene dust floats on the surface, water treatment case 3 side is provided with delivery port 5, delivery port 5 is provided with drainage pipeline 6, drainage pipeline 6 outlet activity connects filter bag 13, with iron wire or anchor ear 18, filter bag 13 can be fixed on drainage pipeline 6 to export, utilize the impact of buoyancy of water and air-flow, polypropylene dust is flowed into filter bag 13 from drainage pipeline 6, the shown mouth of a river 5 height is at water treatment case 3 one middle side part, can not be too low, delivery port 5 is highly too low, a delivery port draining, polypropylene dust is on the water surface, do not discharge, do not have the effect of Chalk-dust filtering, after tested, delivery port 5 is positioned at below water treatment case 3 water level 1-3cm for best, described filter bag 13 internal layer is polytetrafluoroethylpunched punched felt 14, melt spraying non-woven fabrics 15 is selected in middle level, skin forms for glass fibre and Aramid fibers 16 blending, there is high-wearing feature, filter effect is better, the advantages such as long service life, water can be allowed to flow away, polypropylene dust stays filter bag 13 li, filter bag 13 can more renew after having expired, drainage pipeline 6 is provided with the 3rd control valve 19, even if operationally, also filter bag 13 can be changed at any time, increase operating efficiency, reduce the possibility of scalding, the present invention is provided with water pump 8 and is back to use in water treatment case 3 again by the water of outflow, for preventing the water in water treatment case 3 not enough due to evaporation or other reasons, water pump 8 other end is communicated with water source, the first control valve 11 can be closed, open the second control valve 9 moisturizing, when the water level of water treatment case 3 is higher than delivery port 1-3cm, close the second control valve 9, open the first control valve 11 normally to work.
The upper cover of water treatment case 3 of the present invention is removable cover, can change the rubbish of water, the inner alluvial of cleaning.
Water treatment case 3 of the present invention adopts stainless steel material to make with remaining water tank 12, because water treatment case 3 and remaining water tank 12 have water for a long time, water treatment case 3 and remaining water tank 12 non-corrosive can be made in the course of the work, do not affect normal work, if water treatment case 3 and remaining water tank 12 get rusty, polypropylene dust can be polluted, and is worth without collecting.
In order to working condition can be observed at any time, be provided with water level observation window 17 at described water treatment case 3 opposite side, can water level conditions be observed, polypropylene dust accumulation situation and silt depth.
A kind of polypropylene device for recovering powder of the present invention; structure is simple; easy to use; originally the polypropylene dust be discharged in air is changed into from water, carries out filtered and recycled; filter bag 13 good filtration effect, durable, not only protect environment; and the polypropylene powder that collection is returned can continue to use, and has saved resource.
Technological means disclosed in the present invention program is not limited only to the technological means disclosed in above-mentioned embodiment, also comprises the technical scheme be made up of above technical characteristic.
