Abstract

The invention discloses a water-saving device of vegetal-washing factory, which comprises: two laying-up basins in 80steres. First, filling water into the first laying-up basin, to be washed in high pressure, without tap water, but the purified water of first basin; the generated waste water via up-down pool flows back to first basin to deposit the sand, while the foreign matter floats; two basins both have three baffle walls, while the water outlets of baffle walls have filter screen; the water flows through said filter screen to be deposited and purified. The invention adds poaching step after selecting and washing at former producing line, while said step uses tap water, and the waste water via water pump is fed to selection washing machine; the waste water after selecting and washing flows into second laying-up basin; each hour of poaching uses 3t water; and the second laying-up basin can be filled fully in three times; then steering three steering valves; using high pressure to wash the water cycle of second basin, while the first basin is pre-discharged; after washing, collecting and selecting the waste water; and two laying-up basins are used alternatively. The invention can reduce the water consumption from 13t each hour to 3t each hour, which reduces water more than 70% and the application cost.

Description

A kind of water saving facility for clean vegetable plant

Technical field

The present invention relates to a kind of water saving facility, particularly a kind of water saving facility for clean vegetable plant.

Background technology

Along with the increase of agricultural products in China export volume, and the raising of living standards of the people, the demand of clean vegetables is heightened; And, many cities such as Guangzhou regulation: non-clean vegetables must not go on the market, and therefore large quantities of clean vegetables factories is born general clean vegetables factory, per hour water consumption is all at the 10-15 ton, cause the significantly rising of clean vegetables cost, also cause the waste of water resource, more outstanding for this contradiction of lack of water city.

Summary of the invention

The objective of the invention is to develop the water saving facility of cover clean vegetables factory special use.Its basic principle is to wash the dish scheme (soaking and washing---high-pressure wash---letter sorting is cleaned former, water all is disposable uses) the basis on, after cleaning, letter sorting increases rinse cycle, rinse cycle is used tap water, waste water after the rinsing is collected, and is used further to letter sorting and cleans, and the means of waste water reuse after letter sorting is cleaned is in high-pressure wash, recycle 3-5 time, bleed off then.

To achieve these goals, the technical scheme that the present invention takes is: a cover water saving facility for clean vegetable plant: comprise, two 80 cubic metres reservoir, the sink-float pond that one dark 1.2 meters, capacity are 4 cubic metres, two water pumps and three reversal valves, rinsing shower nozzle, three pipelines that catchment mortise and connect them.At first give first reservoir fills with water, regulate each reversal valve, used the purifying waste water of high-pressure wash link extracted from the first pond, the waste water of being produced flows back to this pond through the sink-float pond, and the sink-float pond is tentatively with sediment deposition, and foreign material are floating, and per tour is cleared up once; Three road partition walls are arranged in the reservoir, and water is circuitous therein, slowly mobile, and precipitation purifies, and also slows down the pollution of waste water to purifying waste water of firm inflow; And the delivery port of partition wall all has filter screen; Three reversal valve water inlets all carry filter screen, purify piecemeal.The high-pressure wash link is water 8-10 ton per hour, and per tour water guarantees that substantially vegetable washing water all purifies waste water in 80 cubic metres; Guaranteed that also waste water has the time enough sediment waste; Enter the water preliminary purification of reservoir, dirt is less, and can be regularly clear pond once.

Do not reach food hygienic standard owing to purify the dish of washing, therefore, clean the back in letter sorting and increase rinse cycle, tap water is used in rinsing, its waste water (almost pollution-free) is collected, delivered to the letter sorting cleaning machine by water pump again, the waste water after letter sorting is cleaned flows to the second reservoir; Rinsing is 3 tons of waters per hour, full second pond can be held by three classes, then, the commutation of three reversal valves, allow high-pressure wash with the water circulation in second pond, and the first pond shifts to an earlier date emptying (in case repeatedly use, unhygienic), clean after, regather the waste water that letter sorting is cleaned, two ponds are so staggered uses, and has both satisfied hygienic requirements, water consumption also from per hour 13 tons reduce to 3 tons, the water saving more than 70%.

The specific embodiment

The invention will be further described below in conjunction with accompanying drawing.

Referring to Fig. 1, according to technique scheme, a cover water saving facility for clean vegetable plant: comprise two reservoirs: first pond 1 and second pond 2.At first give first pond 1 fills with water, regulate reversal valve 4, first pond 1 and water pump 5 are connected, disconnected, switch on the pump 5 with second pond 2, water in the reservoir 1 is extracted, send into jetting machine 7 through pipeline 6, the waste water after the cleaning flows into sink-float pond 3 through pipeline 8, tentatively with sediment deposition, foreign material are floating, and per tour is cleared up once; Regulate reversal valve 9, sink-float pond 3 and first pond 1 are connected, disconnect with second pond 2, the water of preliminary purification flows back to first pond 1 through reversal valve 9 in the sink-float pond 3, and reversal valve 9 places the degree of depth middle part in sink-float pond 3.

After cleaning 10, letter sorting increased by one group of rinsing shower nozzle 11, tap water is used in rinsing, catchmented mortise 12 of its waste water (almost pollution-free) is collected, delivered to letter sorting cleaning machine 10 by water pump 13 through pipeline 14 again, waste water after letter sorting the is cleaned mortise 15 that catchmented is again collected, and flows into second ponds 2 by pipeline 16 through reversal valve 17; At this moment, reversal valve 17 connects pipeline 16 and first pond 1, disconnect with second pond 2.

Referring to Fig. 2, Fig. 2 is the structure chart of two reservoirs 1,2, and two reservoirs, 1,2 structures are identical, and capacity all is 80 cubic metres, in three road partition walls 101,201 are arranged, water is circuitous therein, slowly flow, and slows down the pollution of waste water to purifying waste water; And the delivery port of partition wall all has filter screen 102,202; The high-pressure wash link is water 8-10 ton per hour, and per tour water guarantees that substantially vegetable washing water all purifies waste water in 80 cubic metres; Guaranteed that also waste water has the time enough sediment waste; Because the water preliminary purification that enters reservoir, dirt is less, can regularly clear pond once.

Rinsing is 3 tons of waters per hour, and full second pond 2 can be held by 3-4 class, then, three reversal valves commutate simultaneously, allow the water circulation of high-pressure wash with second pond 2, and 1 emptying in advance of first pond (in case repeatedly use, unhygienic), after the cleaning, regather the waste water that letter sorting is cleaned, 1,2 liang of so staggered uses in pond had both been satisfied hygienic requirements, and water consumption is also reduced to 3 tons from 13 tons, water saving reduces and washes the dish cost more than 30% more than 70%.

This water-saving system small investment, cost of use is low, and water-saving result is remarkable, and economic benefit is considerable, and can guarantee to wash the dish quality, is that clean vegetables factory should supporting facility.
