Description

Water treatment membrane element buddha's warrior attendant wire cut electrical discharge machining equipment

Technical Field

The invention relates to the field of water treatment membrane elements, in particular to diamond wire cutting equipment for a water treatment membrane element.

Background

The membrane separation technology is a high and new technology widely used in the fields of water purification, solution separation, concentration, useful substance extraction from waste water and waste water purification and reuse, and has the advantages of simple use process, no need of heating, energy conservation, low-pressure operation, small occupied area of the device and the like. Therefore, the method is widely applied to water treatment in municipal wastewater, municipal drinking water, seawater desalination, electronic industry, medical treatment and medicine, oil extraction and ore extraction and other industries.

The membranes used in the membrane separation process are mostly high molecular organic materials, and can be divided into symmetrical membranes, asymmetrical membranes and composite membranes according to the structure of the membranes, and can be divided into microfiltration, ultrafiltration, nanofiltration and reverse osmosis according to the separation precision, the membranes can be made into hollow fibers or flat plates by considering the actual use condition in the membrane manufacturing process, the membranes of two types are designed and assembled into membrane elements according to a flowing water channel, and the membrane elements can be divided into column type, plate frame type, disc type and roll type membrane elements, and the most common membrane elements are the hollow fiber membrane elements (microfiltration and ultrafiltration) and the roll type membrane elements (nanofiltration and reverse osmosis). In the assembly process of the membrane, glue (usually epoxy, polyurethane, silicone adhesive and the like) is needed to bond thousands of hollow fiber membrane filaments or a plurality of flat membrane sheets, then a column type membrane element and a roll type membrane element are respectively obtained by a packaging and rolling method, and finally the glue packaging end of the membrane element is cut to generate a flowing water (permeable) channel, so that the purposes of water inlet, water production and concentrated water separation are achieved.

The existing end cutting for column type pressure/immersion ultrafiltration components, flat plate type ultra-micro filtration membranes and plate and frame type MBR components usually adopts a saw blade with saw teeth, a circular saw, or a toothless circular saw, or a milling cutter. At present, most of the commercial technologies and equipment are one or the combination of two or more of the technologies and equipment so as to achieve a good cutting effect. However, these cutting methods all have the problems of low processing precision, rough cutting surface, more cutting chips, easy blocking of membrane holes or water production channels by cutting chips, high noise and the like, and particularly, most of the materials used for sealing the assembly are epoxy or polyurethane, while the membrane materials are PVDF/PTFE/PS/PES/PVC/PAN and the like, and the membrane materials and the sealing materials have great difference in hardness and flexibility, so that the existing several cutting technical methods have the problems that the casting surface is well cut, but the membrane cannot be completely cut off due to softness and toughness, partial residue is caused to affect the appearance and the performance, in addition, the cutting angle and speed of the blade can cause the casting material to be cracked or cracked around the membrane, and the cutting surface has the problem of pothole, therefore, the existing cutting technology cannot well achieve good cutting effect aiming at the materials of soft and hard integration, the cutting effect is shown in fig. 11-12, which is very easy to cause the problems of hole blockage by chips, low aperture ratio, edge chipping of glue film threads and poor flatness.

At present, band saws, circular saws or milling cutters for metal cutting are mostly adopted for casting end face cutting of column type, plate type and frame type ultra-micro filtration or MBR components.

The band saw is often used as general cutting means of timber and plastics, and low price, advantages such as easy operation, but the band saw is because of the sawtooth is big, shakes badly, often has the saw mark of cutting, and the saw line can influence the neatness of terminal surface to the cutting piece is great, can lead to the piece to get into the membrane hole and block up the inner chamber of hollow fiber membrane at the gliding in-process of saw blade, thereby influences water production quality and flux.

The circular saw is also general cutting implement, often be used for cutting timber, plastics even metal, because of its rotation rate is high, can greatly improve cutting efficiency, saw cut at a high speed and can reduce the cutting load of every sawtooth, promote the chip removal, prevent that the saw bit from breaking the tooth and becoming curved, saw cut a precision height, no mar, nevertheless can produce a large amount of heats and can't in time get rid of when saw cutting at a high speed, need a large amount of emollient spray lubrication cooling, thereby influence the operation environment, increase use cost, simultaneously according to the increase of cutting barrel diameter, the also corresponding grow of disc diameter, make stability reduce by a wide margin and promote lathe design cost. In addition, according to the increase of the distance between the saw teeth and the thickness of the saw disc, the size and the generation amount of the chips are increased, and then the chips are easy to block the film holes or be clamped on the saw teeth, so that the cutting effect is reduced.

Milling cutter for metal cutting, generally used for precision cutting and carving of metals, ceramics and stones, is a rotary cutter for milling and having one or more cutter teeth, each of which is equivalent to a turning tool fixed on a revolution surface of the milling cutter. The cutting edge cutting at the same time in milling is longer, and has no idle stroke, so the productivity is higher. Most of the cylindrical milling cutters are made of high-speed steel into a whole, the spiral cutting edges are distributed on the outer surface of the cylinder, no auxiliary cutting edge is arranged, and the spiral cutter teeth are gradually cut into and separated from a workpiece during cutting, so that the cutting process is stable. According to different processing requirements, the cylindrical milling cutter is divided into coarse teeth and fine teeth, the chip grooves of the coarse teeth are large and are used for rough processing, and the fine teeth are used for finish processing. Like a circular saw, a milling cutter has high cutting temperature, and requires a large amount of water or cutting fluid to reduce the temperature of a cutter head and a cutting surface, so that a large amount of waste water or organic waste liquid is generated; unlike the former two ways, the milling cutter cuts the surface slowly layer by layer, so that the amount of cutting chips generated greatly increases with the cutting thickness, resulting in a large amount of chip waste; more importantly, the cutting chips can enter the inner cavity of the membrane hole layer by layer in the cutting process, so that the membrane hole is blocked and is not easy to clean, and the service performance of the membrane element is influenced. In addition, the milling cutter is not suitable for cutting soft and high-toughness materials such as high polymer materials, the quantity of chips is large in the cutting process, and the milling cutter is easy to stick to a cutter head, so that the cutting effect is reduced, and the service life of the cutter head is prolonged. The milling cutter cutting equipment has high manufacturing cost and troublesome tool bit replacement, and brings inconvenience to continuous production.

The cutting surface is usually very smooth and flat because the cutting line is very thin, and the shearing cutting force can well cut off soft and hard materials through the unidirectional quick movement of the line, so that the phenomenon of burrs caused by the fact that a soft and tough polymer film is not easy to cut off when a film wire and a glue interface are cut is avoided;

5. the operation cost is reduced. The diamond wire can be repeatedly used, the loss when relatively soft polyurethane and epoxy glue are cut is greatly reduced, the corresponding equipment cost, the occupied space, the manpower and the electric power are all reduced compared with the traditional equipment, the whole production flow is more simplified, and the operation cost is reduced;

6. little environmental pollution and low noise. Cutting chips are greatly reduced, and compared with the traditional cutting equipment, the cutting noise is greatly reduced during cutting operation;

7. according to the invention, air is introduced from the air inducing pipe through the high-pressure fan, cutting scraps on the diamond wire are sucked into the scrap sucking pipeline and are left on the filter screen, scrap sucking and primary cooling are carried out on the diamond wire, then the air passes through the spiral cooling pipe and is further cooled through the spiral pipeline, then the air enters the high-pressure fan through the air outlet pipeline, the air coming out of the outlet of the high-pressure fan forms cold air, the cold air further cools and removes the scraps on the diamond wire, and the scraps are blown into the collecting groove, so that the cutting scraps on the diamond wire are thoroughly removed, and meanwhile, the diamond wire is cooled, so that the later-stage diamond wire can be repeatedly used.

in an initial state, the distance between the fixed clamping block 41 and the movable clamping block 42 is the maximum value, the membrane element 8 is placed between the fixed clamping block 41 and the movable clamping block 42, then the button of the man-machine interaction system 1 is used for pushing the air cylinder 43 to adjust the distance between the fixed clamping block 41 and the movable clamping block 42 until the movable clamping block 42 contacts the membrane element 8, clamping is completed, then the membrane element 8 moves towards the diamond wire reeling and unreeling system through the transverse sliding table 32, the cutting length is controlled through the infrared sensor on the fixed bed and the control of the man-machine interaction system 1, after the membrane element moves to a specified position, the man-machine interaction system 1 controls the diamond wire reeling and unreeling system 2 to work, so that the diamond wire moves in one direction from the paying-off wheel 22 to the take-up wheel 23, and meanwhile, the longitudinal sliding table 31 drives the transverse sliding table 32 to move backwards, so as to complete cutting of the membrane element 8, through the high-speed movement of the diamond wires, the diamond grains on the steel wires are directly utilized to cut and cut the glue layer of the film element at a high speed, compared with the traditional cutting mode, the diamond grains on the diamond wires are slightly raised, so that the cutting gaps (micron gaps and less leakage) are greatly reduced, the cutting scraps can be greatly reduced due to the thin wires (dozens to hundreds of microns) to avoid the mutual abrasion between the grinding materials, compared with the traditional band saw and the traditional circular saw, the thickness of the circular saw can be ignored, the wire diameter and the grain diameter of the diamond grains are very small, so that the cutting scraps are very fine and not easy to block film holes, meanwhile, the automation degree is high, the multi-head multi-wire cutting can be simultaneously carried out, the cutting efficiency is several times or even dozens of times of the traditional cutting, the cutting efficiency is greatly improved, the temperature of the surfaces of the diamond wires after being cut rises, and the cutting scraps are remained on the surfaces, when the diamond wire moves in a one-way mode, the air cooling scrap removing mechanism 7 is started, the high-pressure fan is started, air is guided into the induced air pipe 72, cutting scraps are filtered through the filter screen 78, heat absorbed from the diamond wire is cooled through the spiral cooling pipe 74, then the cutting scraps are blown out from the high-pressure fan 76, the diamond wire is further subjected to high-pressure blowing, and therefore the adhered cutting scraps on the surface of the diamond wire are thoroughly removed, the diamond wire is further cooled, and later-stage circulation is facilitated.
