Abstract

The utility model relates to a novel rice washing machine. The middle part of a separator for rice and sand (8) is provided with an annular water intake canal (13), the inner side of the canal is provided with a plurality of inclined holes (14) which are communicated with the cavity in the separator, and the water drives the rice to rotate in the cavity after injected through the inclined holes (14). A plurality of grooves or bosses (16, 18) are arranged on the inner wall of the cavity, and part of a rice intake pipe (11) is penetrated into the cavity body. Thus comparatively large sand grains are ensured to be precipitated.

Description

Rice-washing machine

The invention belongs to a kind of improvement of device for washing rice.

The device that is used to wash meter class in the market roughly is divided into three kinds: a kind of is device by mechanical agitation type, specially permit out hope as Japan and announce the device for washing rice that clear 49-35425, clear 53-17663, practical new case go out to be willing to that item patent such as the clear 54-16135 of bulletin is introduced, its basic principle is to make mechanical agitator drive rice with power to move in container, reach clean purpose.Another kind is the device that stirs by current, as United States Patent (USP) 4,430, No. 143, Japan specially permit out that hope is announced clear 54-16583, practical new case goes out to be willing to the device for washing rice that item patents such as bulletin clear 54-13414, clear 54-25428 are introduced, its basic principle is to utilize current to drive rice to move in container, and by changing the direction of a stream of water, or deepen to clean effect by net, hole etc.Also having a kind of is the device that utilizes the jet round-robin method, specially permit out as Japan that hope is announced clear 51-20579, practical new case goes out to be willing to the device for washing rice that item patents such as bulletin clear 54-13415, clear 54-13417 are introduced, its basic principle is to adopt the power of the water generates of certain pressure, rice in making in the container circulates through jet pipe repeatedly with current, because the continuous purpose of injecting fresh water, having reached clean rice class.The homemade rice-washing device of China mostly is this kind device.

Use above-mentioned three kinds of devices, once can clean a large amount of rice, alleviate the intensity of hand labor.Wherein last a kind of rice-washing device also can be isolated a small amount of grains of sand according to different specific weight.But they generally all exist husky clearly rate very low or at all can not be clearly husky shortcoming.Units concerned once did performance test to the double-vane board rice-washing device of domestic employing jet round-robin method, found that this product once recycles husky rate only about 24%.Because China east and South Asia vast product meter district mechanization degree is not high, threshing grain all directly contacts with ground with drying to wait, thus meter in silt content bigger, said apparatus can not fully meet the demands.

Task of the present invention is structurally improved the circulating rice-washing device of existing jet, improves clear husky rate greatly when not reducing clean effect.

For achieving the above object, the present invention adopts the husky separator of rice with exocentric structure.In design water velocity in the separator cavity and direction are controlled in addition, guaranteed that the bigger grains of sand of proportion can sink to cavity bottom smoothly.

Below in conjunction with accompanying drawing the present invention is done and to specify:

Accompanying drawing 1 is the general assembly diagrammatic sketch of this rice washer.

Accompanying drawing 2 is the sectional view of the husky separator of rice washing machine-processed rice.

Accompanying drawing 3 is a rice husky separator cavity top profile (A-A section)

Accompanying drawing 4 is a rice husky separator cavity bottom profile (B-B section).

Label is in the accompanying drawing: 1 goes out a meter bend, 2 gaps, and 3 connect sleeve pipe.The 4--rice storage barrel, the 5--rice outlet tube, 6--decimetre awl, 7--supporting leg, the husky separator of 8--rice, the 9--rubber tube of intaking, 10--rice storage barrel foot passage, 11--advances mitron, the 12--water inlet pipe, 13--ring-type intake tunnel, the 14--inclined hole, 15--separator cavity top, approximate centrifugal water pump inner chamber, the 16--transverse concave groove, 17--separator cavity bottom, 18--longitudinal fluting or boss, 19--dewatering orifice, the 20--three-way pipe that discharges water, the 21--spool 22--handle that discharges water.

With reference to accompanying drawing, advance mitron (11) one ends and be socketed on the rice storage barrel foot passage (10), the other end deeply advances in the husky separator cavity of rice, and its lower limb position is about the cavity middle part.Ring-type intake tunnel (13) is located at the husky separator of rice middle part, has several inclined holes (14) on its madial wall, and lateral wall and water inlet pipe (12) are connected.Have all transverse concave grooves (16) on the cavity inner wall nearby in ring-type intake tunnel (13) lower end, offer some longitudinal flutings or boss (18) from lower edge to the cavity bottom of transverse concave groove.

During use, rice grain pattern in the rice storage barrel (4) is crossed decimetre awl (6) and is entered rice husky separator (8) through advancing mitron (11), with water inlet pipe (12) water of certain pressure is injected cavity through ring-type intake tunnel (13) by inclined hole (14), drive rice together rotated at cavity middle part and bottom after water entered cavity, and flowed to separator (8) top.Deeply enter the interior position of cavity owing to advance mitron (11), rice sand just can enter cavity top after must rotating by cavity bottom to middle part, thereby sand can directly not be brought into rice outlet tube (5) from cavity top.The transverse concave groove (16), longitudinal fluting or the boss (18) that are opened on the separator cavity inner wall can reduce near speed and the direction of current cavity inner wall, thereby make bigger grains of sand crossheading road of proportion and boss edge sink to cavity bottom, the rice that proportion is lighter is brought separator cavity top (15) into rotary water current.The grain of rice can rise to than the higher position of rice storage barrel (4) liquid level under the hydraulic pressure effect, forms circulation elutriation process.

Through inventor's test, it is about 96% that this rice washer once recycles husky rate, guarantees Mi Zhongwu sand substantially through twice Cyclic Rings.This device also can be used for the wet separation of the different granular object of two or more proportions.

Claims

1, a kind of rice washer, by rice storage barrel (4), advance mitron (11), water inlet pipe (12), rice husky separator (8), go out rice and jettison gear is formed, it is characterized by at the husky separator of rice middle part and be provided with a ring-type intake tunnel (13), have several inclined holes (14) on its madial wall and lead to the internal cavity of separator, lateral wall and water inlet pipe (12) are connected.
