Abstract

The utility model discloses an automatic rice washing and sand filtering device for a collectivity dining-room, which is suitable for separating sand in all the edible particles, which are mainly rice particles. The device comprised a rice washing and sand filtering channel, which comprises a negative pressure zone, a slow flow chamber, a sand filtering groove body, etc. The utility model is characterized in that the communication with the negative pressure zone can achieve rice washing in an automatic cycle; the sand filtering and the rice discharging are realized through the slow flow chamber and the sand filtering groove body.

Description

Automatic rice washing and sand filtering device for dining-room

The utility model is the separator about rice and sand grains, the automatic rice washing filter sand device that particularly a kind of energy uses for collectiveity canteen.Be suitable for separating sand based in all food grain things of rice.

Existing collectiveity canteen is done the big capacity rice washing of ante cibum, has both required rice washing speed to want fast; Require filter sand rate and automaticity to want high again.China's utility application 35203030 rice washers also have a rice sand separator, but because separator cavity inboard wall groove or boss are subjected to the restriction of bulk, the requirement that sand grains precipitates can not be satisfied in its angle of inclination under the hydraulic pressure flow action, particularly fine sand grains is pulled away with current easily; On the other hand, separator is to the strictness of hydraulic pressure control range: big, do not reach the filter sand purpose; Little, push away the motionless grain of rice, and easily the separator inner chamber is blocked.Moreover, carry out the second time and eluriate, must bleed off the sand of depositing in the separator.So rice washing speed is slow, sand production rate is also not really high, reach the requirement in existing dining room, and very big difficulty is arranged really.

Task of the present utility model is that a kind of very simple and convenient and the automatic separation rice that the filter sand effect is splendid and the device of sand grains will be provided.

The utility model is finished in such a way: the affixed siphunculus more than of staving bottom bell mouth place, one of many siphunculus inwardly are equipped with nozzle, being positioned on the same axis of nozzle another inwardly is anemostat, the running water of introducing is ejected in the anemostat after the nozzle bore supercharging, make bell mouth place form negative pressuren zone, by anemostat, the circuitous widely different two-way fork that makes progress into of pipe, the one tunnel leads to the top of staving to the grain of rice under suction function in the bucket, get back to negative pressuren zone, form the rice washing closed circuit; Two the tunnel constitute filter sand through unhurried current chamber, outlet, convex mouth, filter sand groove body goes out a meter main road.

The utility model structure is quite simple, as long as utilize life with the hydraulic pressure of running water or have the condition of water-head, just can realize the big capacity filter sand of washing rice automatically easily, must not control range hydraulic pressure, rice washing speed soon, filter sand effect ideal extremely.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is details and the working condition according to the concrete device that the utility model proposes.

This device mainly includes a negative pressuren zone (14), many siphunculus (9), nozzle (7), anemostat (11), unhurried current chamber (20), filter sand groove body (24).With reference to Fig. 1, anchor tip (10) has been located in the bottom bell mouth (14) of staving (13), a three-way pipe (9) connects into an inner chamber body with joint (10), one of three-way pipe (9) inwardly is equipped with nozzle (7), and nozzle (7) is outer to have joint (6), pipe (5), water pressure gauge (4), valve (3), step pipe (1) fixedly connected successively.Being positioned on the same axis of nozzle (7) another inwardly is anemostat (11), anemostat (11) is outer to have the fixedly connected and circuitous widely different two-way that makes progress into of pipe (5) to diverge, one the tunnel leads in the top of staving (13), the two tunnel directly into the unhurried current chamber (20) loam cake in.The end of two-way pipe is equipped with rice washing valve (16) and filter sand valve (19) respectively.Unhurried current chamber (20) is positioned at the top of staving (13), has horizontal strip outlet (21) in it, its outer convex mouth (22) that is extended with.Filter sand groove body (24) is made up of the groove (23) of some, tilts to be socketed on the convex mouth (22) of unhurried current chamber, and its inclination angle is preferably between 20 °～30 ° to improve the filter sand effect.The top of staving (13) also has spout hole (17), and the bottom is fixed with stent foot (12).

The process of rice washing filter sand is: according to eater's quantity, the rice of needs is directly poured in the bucket (13), filter sand groove body (24) underlying one connects a meter device, save flexible pipe water valve and step pipe (1) connect from the beginning with one then, then, turn on water valve from the beginning, the handwheel (2) of inlet valve (3), water pressure gauge (4) work, and then, the handle (13) of filter sand valve (19) is put the position of pass, plate fixed handle (15), the conducting of rice washing valve (16), accumulate in the grain of rice that negative pressuren zone (14) locates was siphoned away and pressed to bucket (13) rapidly by current top, automatically circulate and eluriate rice, when the inner bucket water position is increased to spout hole (17), swill just excretes out from the hole slowly, by the time when the water in the bucket (13) becomes clear by muddiness, rice has just been eluriated well, at this moment, need only the position that handle (18) is put out, turn off the handle (15) of rice washing valve (16) rapidly, filter sand valve (19) conducting, under the hydraulic pressure effect, rice and sand grains are through unhurried current chamber (20), outlet (21), convex mouth (22), groove body (24) flows out.When moving to the groove (23) in the groove body (24) under the percussion at current when rice and sand grains, proportion just begins to be deposited in the groove (23) greater than the sand grains of rice, by some and have each groove width, groove depth is identical or during vicissitudinous groove (23), sand grains just all is deposited in the groove (23) and has reached the filter sand purpose, at last, turn off valve handle, take off groove body (24), the sand grains that will accumulate in the groove (23) is removed clean, stand-by.Here it is worthy of note: as be flushed at last, still have a small amount of grain of rice to remain in the groove (23), as long as gently hug several descend with finger in groove, the residual grain of rice has just remained little; As the speed of needs control rice washing filter sand, can adjust valve handle (2) according to the reading on the water pressure gauge (4) and just can realize.When pressure is 1.5 kilograms per centimeter ²The time, the whole elutriation filter sand process of 25 kilograms of rice only needs a few minutes.

This device only requires nozzle a few parts such as (7) is processed that wherein the size of nozzle bore (8) preferably keeps being pressed into running water the relation of direct ratio, to realize supercharging and to keep certain flow value; Remaining parts all can be obtained by commercial standard component.Metal, plastics all adapt to this device, so cost is cheap especially.
