Abstract

The present invention relates to an ultrasonic washing machine which is mainly composed of a gas bubble supply device and an ultrasonic generator. Textiles, such as fiber, yarns, threads, etc., are put into a cylinder which is filled with water so as to make the ultrasonic generator operated. Gas bubbles are generated on the surfaces of the textiles because of the function of cavitation erosion to help to remove dirt, abnormal substances, etc. attached on the surfaces. Part of air which is supplied from exterior by the gas bubble supply device is dissolved in the water, and therefore, the air which is consumed because of the function of cavitation erosion is replenished. When rest of the air which is not dissolved in the water becomes the gas bubbles to ascend, ultrasonic waves have many opportunities to generate diffuse reflection on the surfaces so as to perform the function that cleaning effects are improved obviously.

Description

Ultrasonic washing machine

The present invention is the ultrasonic washing machine about the textiles that is used for washing the fibre and yarn and so on; It has installed a supersonic generator and an air bubble supplier.

The washing machine of habitual washing textiles generally has an agitator and stirs them with washing agent; Therefore need sizable heavy-duty motor to start agitator.And the textiles after washing will certainly fold, coil buckling or damage.Certainly, the infringement that is caused by washing agent also can not be avoided.Except above-mentioned and, in the refining workshop of weaving, also once used another kind of washing machine to be used for the flush away spot, as the finishing material on the oil content that adhered in the past at dyeing process or fiber, the yarn textiles.This a kind of washing machine has structure shown in Figure 4.Promptly in bucket 110, installing the rotating cylinder that many holes are arranged on its wall; This rotating cylinder is flatly supported by a fixed eccentric shaft 113.Thereby cause vibration with certain speed.Above the bucket 110 that is full of washing agent, be provided with tension force running roller 114; Therefore, as the long fiber textiles 120 after washing is after carrying out a trip on the rotating cylinder 111, just sent by guiding continuously from bucket by tensioning running roller 114.Textiles is wound onto on the rotating cylinder 111, and rotating cylinder relies on the effect of fixed eccentric shaft whenever to carry out a vibration period property motion, washing just can be back and forth by the eyelet of textiles.Based on this situation, the spot on the textiles will have been washed off the vibratory impulse of textiles owing to washing agent.Yet the two gives and very big vibration this washing machine to rotating cylinder and textiles, so that rotating cylinder needs large-scale and firm structure, so the result is that textiles will certainly suffer damage.

In this case, a project of the present invention provide one one small-sized, energy-conservation, do not need washing agent and be suitable for washing the ultrasonic washing machine of textiles.Another purpose of the present invention provide one one can washing the fibre, class textiles such as yarn, rope yarn and harmless ultrasonic washing machine.

Purpose above-mentioned and in addition of the present invention and novel characteristics by following detailed description, and when reading in conjunction with the accompanying drawings, can more fully show.Yet, obviously self-evident.Accompanying drawing is just in order to explain, rather than in order to limit scope of the present invention.

Fig. 1 is the perspective view that the part of washing machine of the present invention cuts.

Fig. 2 is the skiagraph of expression second example of the present invention.

Fig. 3 is expression and second skiagraph that example changes to some extent.

Fig. 4 is in order to express the skiagraph of habitual washing machine more here with above-mentioned second example.

In Fig. 1, express the washing machine that is used for washing textiles, as first example of the present invention.The open-topped metal rounding cylindrical tub of numeral 1 expression among the figure.On its bottom surface 11, wearing many apertures 12.Also make many sheet metals 13, their the irregular all directions that facing are erected on the bottom surface 11.

At the center of bottom surface supersonic generator 2 is set, its ticker 21 protrudes in the bottom surface of bucket; The joint of ticker will be sealed to water-tight state near the bottom surface.The comparatively thick wire netting of eyelet protects cage 23 and is covered with ticker 21.By means of dial type selector (here without diagram), for example,, the frequency of supersonic generator is changed in 10～60 kilo hertzs scope arbitrarily simultaneously according to the kind of the textiles that will wash.Promptly with regard to the material of textiles, according to the order of artificial fibre, cotton, fiber crops, silk, wool, nylon, frequency will increase in above-mentioned scope successively.Frequency also will be adjusted according to the weaving manner of textiles again.Consider this point, natural ultrasonic wave acoustical generator will design like this, so that frequency can become optimum value in above-mentioned scope.

For the ultrasonic wave that has taken place can be propagated in the full bucket equably, wish that ticker does not have directionality.Have at ticker under the situation of directionality, in bucket, arrange many tickers, so that carry ultrasonic wave, or in bucket, arrange many reflectors, so that ultrasonic wave causes diffuse reflection thereon to each direction.

For reflection supersonic wave effectively, washtub will be made of metal.But it can apply one deck synthetic polymer, the hyperacoustic reflection of the very thin unlikely obstruction of its bed thickness.

Between bottom surface 11 of boring a hole and base plate 32, form bubble supply chamber 33.At the periphery top of bucket installing air pump, so that air is sent into the bubble supply chamber by pipe 31.Air can be sent in the bucket by porous material or by the many apertures that wear on base plate.Water discharge outlet 15 on the bottom surface 11 is similar with the osculum 35 on the base plate 32, all guides to switching valve 4.Here by pipe 41 a part of waste water is discharged, all the other then can arrive pump 43 by filter 42, and it and water intaking valve 44 are connected.The pipe 45 of supplying with fresh water also is connected to valve 44.Because a part of waste water circulates by water discharge outlet, valve 4 and water inlet, utilize again, so just can significantly reduce water consumption.

Each face of many metal system lugs at the bottom of being located at barrel is during brokenly towards all directions, and the ultrasonic wave that is taken place just has and caused diffuse reflection on it, spreads all over full bucket equably, and water is soaked in the textiles well.Like this, just can expect that washing is more effective.

Operating procedure in first example of washing machine of the present invention is described in more detail in down according to accompanying drawing: the ratio according to clothing class quantity begins to supply with an amount of water, puts within the bucket 1 by water inlet pipe 45.At this moment, 4 pairs of pumps 43 of valve are cutting out.Secondly, wish the clothing class that similar textiles is formed is placed within the bucket 1.They sink in the water soon, because metal system lug 13 is erected at the bottom surface, can not accumulate in a place; The clothing class absorbs enough water, and not residual in its surface what air, in order to be made for reference, to stir the clothing class with hand and can more help from wherein removing air.

Be suitable for washing on the frequency of textiles on the supersonic generator 2 a dial type frequency selector being set in, start supersonic generator then; At this moment ultrasonic wave has just taken place in ticker 21, and a part wherein is by protecting the eyelet of cage 23, causes diffuse reflection after perhaps impacting on the eyelet, arrives then on the textiles; Another part also causes reflection after on the metal system of impacting lug 13 and bucket 1 inside, arrive on the textiles then.Like this, owing to form such ultrasonic wave network, just can wash effectively.

Specify that when the water of clothing class absorption volume, when consequently air did not exist, a part of ultrasonic wave just directly arrived on the clothing class, the acoustic impedance (2.9 * 10 of clothing class thereon ⁵Centimeter-gramsecond) closely equals the acoustic impedance (1.5 * 10 of water ⁵Centimeter-gramsecond), hyperacoustic reflectance factor and absorption coefficient are about 0.097 and 0.903 separately; This just means and has been absorbed about 90% ultrasonic energy by the clothing class.Yet the eyelet of textiles is thicker, and ultrasonic wave is because cavitation effect just can pass through several textiless, and cavitation effect helps to remove spot from textiles.

Take place hyperacoustic while or after, air pump 3 works together, and ambient air is sent in the bubble supply chamber 33 by pipe 31.Send into indoor air from many perforation of bottom surface, rise in water with the form of minute bubbles, a part of gas bubble is in water, and all the other are then keeping bubble shape to arrive the surface of water.Therefore these bubbles make ultrasonic wave have more chance to cause diffuse reflection thereon, and help it to spread all in the bucket equably.Reflection on the bubble is from acoustic impedance difference big between the water and air.Ultrasonic wave does not directly arrive textiles, but arrives the inwall of bucket, impacts on the textiles at last after reflection.

Like this, the ultrasonic wave that impacts textiles is because just gassing on the surface of textiles of cavitation effect, and it makes spot or foreign peoples's material break away from textiles, as long as cavitation effect is proceeded, after experience a period of time,, just can reduce the formation bubble because the air that is dissolved in the water is used up.Yet as mentioned above, the portion of air of giving from bubble supply chamber 33 but is dissolved in the water gradually, so that often forms bubble, and does not disappear.Therefore, spot or foreign matter are just removed fully.

After washing, close and stop supersonic generator 2 and air pump 3.When forwarding to valve 4 in the pipe, just from pipe 41, discharge bucket 1 with interior and bubble supply chamber 33 with interior waste water.Do not wash if do not discharge waste water next time, then valve 4 is forwarded in the pump 43, and make pump 43 work.Waste water filters by filter 42, and sends within the bucket 1 by valve 44 again.Filter is to replace, and waste water can utilize once more; Therefore can save quite a large amount of water.

After first example, second example reaches with its example that changes to some extent and will be illustrated according to Fig. 2 and Fig. 3, and wherein identical with the parts of first example parts and the actual identical parts of effect thereof are all pointed out by the same numeral among Fig. 1.In Fig. 2, almost the central horizontal of bucket 1 supporting the rotating cylinder 52 that many holes 51 are arranged on periphery, on the perforation rotating cylinder, twining rectangular textiles or a branch of yarn A, and giving and pulling force by tension force running roller 53; Therefore, the speed that textiles A can be certain is by this bucket.

This barrel is full of a large amount of water at first, so that do not have this rotating cylinder at least.At this moment valve 4 is closed reversing pump 43.Secondly, the frequency selector on the supersonic generator 2 is set in is suitable for washing on the value of textiles, and start supersonic generator.Ultrasonic wave takes place, and wherein a part directly arrives on the textiles, and another part then causes reflected-shock on the inwall of bucket 1, arrive on the textiles then.

Take place hyperacoustic while or after, make air pump (not shown) work here, and air sent in the air bubble supplier 3.Sending into indoor air then rises water with the form of minute bubbles in the many holes 36 on being located at air bubble supplier.Part bubble enters rotating cylinder inside by the hole of both sides.Part bubble is dissolved in water when it rises in the water, but all the other are then keeping bubble shape to arrive the surface of water.Therefore the bubble-help ultrasonic wave constantly causes diffuse reflection thereon, and spreads all over equably within the bucket 1.Part bubble impacts the inboard of bucket.Cause reflection thereon, and enter rotating cylinder by the hole of both sides; Part bubble then by hole 51 and such as fiber and yarn the eyelet of textiles enter rotating cylinder, and impact its inside, keeping contacting with rotating cylinder.Because a part of bubble constantly is dissolved in the water, so the air in the water can be owing to cavitation effect exhausts; On the contrary, but gassing is constantly removed spot or foreign peoples's material easily from textiles.

Simultaneously, the example that changes to some extent with second example is identical with second example notion in essence at it.Yet, in the example that this has changed, can experience long-time washing for making textiles, in a long bucket interlaced arrangement roller 8 of minor diameter, as shown in Figure 3, its structure is to make the ultrasonic wave that has taken place can impact its both sides equably.In addition, they also distribute fully, and cause the rotating cylinder of roller unlike second example, need perforation.Therefore, washing can be carried out very effectively.
