Description

Method and instrument of hydraulic spray circulation washing

The invention belongs to the method for coming article-cleaning with the current jet power; Also be a kind ofly to handle agricultural byproducts, particularly clean the equipment of vegetables.

In the more collectiveity canteen of edible vegetable, restaurant or food processing industry, dish or the churned mechanically dish mode of washing are manually washed in employing usually at present.Adopt these to wash the dish mode, the cleaning of silt particle, not high, the fresh and tender vegetables cracky of separating degree in the vegetables, water consumption is big, labour intensity is big, efficient is low.

" Soybean washing machine " (CN ZL 85 201102) of Beijing Foodstuffs Inst.'s invention, employing is tangentially sent into separator with soybean, clear water mixture by delivery pump, between the inside and outside tube of separator, form outer vortex that is rotated down and the inside vortex that rotates up, utilize the difference in specific gravity (about 1: 5) of soybean and stone, clipped wire, soybean is risen along inside vortex, discharge by discharge gate by the separator inner conical-tube; Stone, clipped wire drop to the washing soybean method that scum pipe is discharged along outer vortex.Adopt this method, because beans, aqueous mixtures contact the impeller of delivery pump high-speed motion by brute force suction, row and the mixture of delivery pump, pipe, as be used to clean rhizome vegetable or leafy vegetable, will produce serious damage, fester, therefore, can not be used for dry bean agricultural product in addition cleans.

The objective of the invention is to overcome the deficiency of prior art and a kind of method and apparatus that comes article-cleaning with the current jet power is provided.

Fig. 8 is that sink is communicated with the situation schematic diagram with sedimentation basin.4 is sink among the figure, and 5 is filter screen, and 9 is sedimentation basin, and 8 are overflow lock and overfall.

During cleaning, start water pump 1, article are poured in the sink 4; Water pump 1 sucks the clear water in the cistern 3, sends into respectively in the several playpipes that are contained in the sink by water pipe; The current of playpipe ejection are pressed certain direction and angle directive cleaning materials in sink. Trench bottom at sink is provided with a passage that is connected with sedimentation basin 9, and the filter screen 5 that a slightly inclined is installed is housed on the passway; Under the effect of waterpower, cleaning materials circulates in sink by water impact and with current, and silt separates gradually with cleaning materials and leached gradually by filter screen; Current and silt enter sedimentation basin 9 by filter screen, and a large amount of sediment settlements are in the bottom of sedimentation basin, and the washings after the precipitation flow into cistern, suck again recycling by water pump after the cistern secondary precipitation by overflow lock 8. Wash complete after, open the gate 7 of originally shutting, shut the gate 6 of originally opening, by injection water cleaning materials is gone out, flowed in the access container, until after cleaning materials is all emitted with current in the groove, close again brake application 7, open lock 6, enter next time cycles of washing. Depending on kind and the quantity of cleaning materials, the water level of overflow lock 8 capable of regulating sinks makes the water level of sink be in the optimal cleaning effect position.

Adopt method of the present invention washing fresh vegetables, washing speed is fast, generally whenever finish one the washing cycle-promptly reach desirable wash degree requirement, only need 2～3 minutes (cleaning thing circulates about 10 times) in sink; Water-saving, the vegetables about 400 kilograms only need about 2M ³Water, one man operation can wash about one hour.When utilizing small-sized freezer refrigeration compressor cooling water for the washing water source, water-saving result is more remarkable; Be cleaned the few breakage of thing, fester, even fresh and tender leafy vegetables such as green vegetables, spinach also are like this; The kind of thing capable of washing is many, as green vegetables, spinach, celery, Ipomoea batatas (sweet potato), potato, soybean, beet etc., when all genus separates silt impurity in the agricultural product, substantially all can adopt this method and equipment.Be particularly suitable in collectiveity canteen, restaurant, hostel, hotel or the food processing industry, clean preparation as the vegetable raw-material before the cooking.

Embodiment one:

Cistern, sink, sedimentation basin adopt brick formula (referring to Fig. 2,3,8), and sink is built into Long Circle.Four playpipes are installed in that cell wall is vertical, injection direction for along or counterclockwise (must make current can in groove shuttling movement).At groove bottom part one gradient being installed is about 1: 60 6～8 mesh filter screens, and filter screen is connected with sedimentation basin down.

Lock

6,7,8 is all made with sheet iron or plank, and lock 8 can adopt the different plank of polylith width or other positioners to adjust flood level.Adopt the 3BA-13B water pump, operating pressure 0.05～0.1MPa, lift are 12 meters, flow 34.2M ³/ hour, adapted power of motor 2.2kW; The cistern capacity is 2M ³Washing capacity: about 25kg/ time of green vegetables; Adopt the Long Circle sink, groove width 300mm, groove depth 450mm, flute length 2000mm is about centre-to-centre spacing 1500mm.

Embodiment two:

Referring to Fig. 4, variable cross-section shape sink.Its basic configuration still is a Long Circle, but respectively increases by a flange at A, B place that circular arc is connected with straight line, to circle round and produce unwanted sediment deposition phenomenon in the part of reducing current; Sink bottom surface curve also is designed to be uneven, and makes at the situation bottom surface that does not wash and does not retain residual thing and water (referring to Fig. 5).Circular arc connection outer wall place is provided with some wing flanges in sink simultaneously, the upset so that the cleaning thing is in the suds, increase cleaning performance.

All the other are with embodiment one.
