{WATER-PRESSURE RICE WASHING MACHINE THAT PREVENTS BROKEN RICE-GRAINS}

The present invention is characterized in that it comprises a water injection nozzle and an external air mixing means composed of an air nozzle for sucking outside air on the side of the spray nozzle of the water pushing the rice through a semi-pipe of a hydraulic pressure semi-tank. When water is sprayed from the spray nozzle, The present invention relates to a semi-automatic water pressure semi-machine which is capable of preventing the water from spraying due to the buffering action of bubbles when water is mixed with a small number of small air bubbles in the water sprayed while the outside air is sucked into the air nozzle by the negative pressure will be.

In general, a semicircle for washing a large amount of rice for group feeding is a semi-batch type semi-batch machine in which semi-batch rice is cleaned by a rotary stirrer, and rice in a semi-batch is transferred to a semi-tube by high- Two types of hydraulic press machine are mainly used.

The stirrer has the advantage of cleaning a large amount of rice more rapidly, but has a drawback that the rate of run is high.

In addition, the hydraulic pressure of the rice paddy is lower than that of the stirring rice paddy, but the rice paddy rate is lower than that of the stirring paddy during the rice paddy.

An example of the prior art relating to the hydraulic press machine according to the present invention is as follows.

(1) The electric type hydraulic semi-automatic machine of the Utility Model Bulletin No. 20-1996-0005852 (Notice of July 18, 1996) is designed such that the cross-connection pipe is connected to the lower end of the semi-tank and the water contained in the semi-tank by the motor pump connected to one side of the cross- The water is sprayed by a semi-pipe connected to the other side of the cross connection pipe, and the water and rice are washed by the water pressure while the water and the rice are moved to the semi-pipe, and a reflection plate and a spray plate having a plurality of cut- As the rice is dispersed, the cleaning effect can be increased.

② Registered Utility Model Registration No. 20-0295038 (registered on Oct. 30, 2002), the electric semicircle of the basket contacts the spray nozzle and the semi-pipe at the lower end of the basket, so that the rice and water are cleaned while being moved to the semi-pipe by water pressure When the water pressure becomes higher than the set pressure by adding the simultaneous electronic control unit, the operation of the electric pump is automatically stopped and the cleaning time is arbitrarily controlled by the timer.

③ Registered Utility Model Registration No. 20-0221846 (Registered on Feb. 15, 2001) has a pressurized rinse water spray tube and a transfer pipe for pressurized rinse water are formed at the lower end of the rinse tank to transfer rice and water by water pressure A skimmer is provided on the upper side of the simultaneous cleaning tank for cleaning the rice while the rice is being conveyed to the pipe, so that the rice is cleaned while removing impurities suspended in the washing water.

④ The water saving automatic machine of public utility model No. 20-2009-0012379 (Dec. 3, 2009) is designed to spray water from the nozzle formed at the lower end of the water tank and to clean the rice while discharging rice and water to the discharge pipe The air spouting tube is spirally installed in the water tank, and the water is saved by storing the washing water in the simultaneous water reservoir which improves the cleaning effect by irregularly turning the rice by the air ejected from the air spouting tube into the water tank.

Although the above-described conventional hydraulic pressure unit has an advantage of lowering the cut-off rate during washing compared to the stirring semi-batch, since the high pressure water is used to clean an actual large amount of rice in a short time, the cut-off rate is usually 10 to 13% .

The heat loss occurs mainly when the high pressure water sprayed from the spray nozzle and the rice called water collide with each other. However, the means for preventing the heat loss is not disclosed in the prior art.

In the water-saving automatic semi-machine of the prior art ④ of the Utility Model No. 20-2009-0012379 (published on Dec. 3, 2009), an air spouting pipe was installed in the water tank and the rice was irregularly turned There is, however, an attempt to have semi-action by irregular turning of rice in the tank, and it has nothing to do with preventing seasons.

Generally, the hydraulic pressure unit is provided with a branch tube at the lower end of the semi-tank installed in the base, the spray nozzle of water is mounted to one side of the branch tube in the lateral direction, and the inlet of the semi- , The rice in the semi-tank is washed by the water spray while the rice is moved from the branch pipe to the semi-pipe, and the overflowing water in the semi-tank is drained to the overflow drain pipe, and the rice is circulated repeatedly in the semi-pipe.

Since the water used to clean rice is a liquid, there is almost no change in the density of water molecules even when pressure is applied at a certain temperature. Therefore, when water is sprayed onto rice at a predetermined pressure, water pressure is directly applied to the surface of rice, Weak rice is easily broken.

The inventor of the present invention believed that since air has a low specific gravity and can change the air density according to the pressure even at a constant temperature, the inventor believes that there is a good buffering function in comparison with water. In cleaning the rice by the hydraulic pressure machine, And the means of injecting air bubbles into the water sprayed from the nozzle.

However, it is not simple to incorporate air into the water sprayed from the spray nozzle of the water to push the rice into the semi-tubular. It is very difficult to control the hydraulic pressure and the air pressure in a balanced manner when air is injected into the water pipe of the water jet nozzle by using the air pump.

When the air pressure is higher than the water pressure, the air bubbles become large, and a large amount of air is discharged from the water spray nozzle, causing a large flocculation, so that the bubbles can not easily flow into the semi-tub.

 Further, when the air pressure is lowered compared to the water pressure, the water in the water tube flows back to the air supply side and bubbles are not formed.

In addition, in the case where the spray nozzle and the air nozzle are installed side by side in the lateral direction of the semi-tubular branch, the spraying power of the water is lowered due to the action of the fire in the branch pipe,

An object of the present invention is to provide an apparatus and a method for supplying rice to a semicircular tube by means of mixing means for mixing outside air composed of an injection nozzle for water pushing rice of a hydraulic pressure machine into a semi-pipe and an air nozzle for sucking outside air, Which can prevent run-off due to the buffering action of numerous small bubbles which are mixed in water.

Another object of the present invention is to provide a semi-semi-permanent water pressure semi-machine which can be effectively semi-cleaned because of simple construction of the air mixing means and simple maintenance and easy operation.

 In the present invention, a spray nozzle of water is mounted on one main surface of a branch pipe connected to the discharge pipe side of the lower end portion of the funnel-shaped semi-tank installed in the base, the inlet port of the semi-pipe is inserted into the other main surface of the branch pipe, Wherein a bending pipe capable of pivoting is guided to an upper side of a semi-tank, a train cock is provided at a lower end of the branch pipe, and an overflow drain pipe is provided at a side of the semi-tank,

An external air mixing means of an air nozzle is coupled to the injection nozzle side of the water provided in the branch pipe so that external air is naturally introduced into the water through the air nozzle by the negative pressure generated around the injection nozzle when water is injected And is characterized in that when the water sprayed to push the rice into the semi-tubular structure collides with the rice, it is possible to prevent the steam from buffering due to the buffering action of a large number of bubbles mixed in the water.

The air mixing means comprises a combination of an injection nozzle for water and an air nozzle for piercing air supply holes for sucking air from the outside.

The spray nozzle of the water basically has no difference from the function of a general water spray nozzle, but is structured to be coupled with an air nozzle for mixing air. That is, the spray nozzle of the water is provided with a head having an inner diameter sized to be inserted tightly into a hole formed in the main body of the air nozzle with an end at an end of the main body, A cone type nozzle having a jetting hole formed on the tip end side of the nozzle is formed.

The air nozzle sucks outside air by the jetting force of the jet nozzle of the water. The air nozzle has a hole having an inner diameter sized to allow the head of the jet nozzle of water to be inserted into the body of the air nozzle And a head portion having a smaller inner diameter to be inserted into a mounting hole formed in the branch pipe is formed at the front end portion of the main body and an ejection hole through which water and air bubbles are ejected together. The ejection hole is larger than the inner diameter of the injection hole. In addition, the air supply hole associated with the air supply pipe is perforated at a position close to the head of the main body of the air nozzle, and the air supply pipe associated with the air supply pipe is led to the upper side along the side of the semi-tub.

The head of the water jetting nozzle is inserted into the air hole of the air nozzle so that the jetting hole of the water jetting nozzle and the jetting hole of the air nozzle are located before and after the same axial line, the water nozzle is located at the air supplying hole of the air nozzle, The external air is sucked into the air holes of the air nozzles through the air holes of the air nozzles by the suction force of the jetting force injected from the air nozzles.

 According to the present invention configured as described above, the rice to be cleaned is poured into the semi-tub, the valve of the water tube is opened, and the water is sprayed to the jet hole of the water jetting nozzle at a predetermined water pressure. The rice contained in the semi-tank flows into the inlet of the semi-pipe through the water pressure of the water sprayed from the spray nozzle, and the rice is circulated together with the water through the semi-pipe and the curved pipe to the upper side of the semi-tank, The water that continues to flow along with the rice in the curved line is drained into the drain pipe of the opler, and the rice is repeatedly washed without overflowing to the outside of the semi-tub. The rice which has been cleaned is put into the other container by turning the curved line to the other side. The rice is put into the semi-tank again and the rice is washed. When the washing is finished, the train cock is opened to drain the water contained in the semi-tank. This semi-procedure does not differ from the normal operation of the hydraulic system.

Meanwhile, in the semi-process of the present invention, when water is sprayed from the spray nozzle of the water in the above-mentioned semi-process, external air is sucked into the hole of the air nozzle through the air supply and discharge holes by the negative pressure generated around the spray nozzle The air is injected into the ejection hole of the air nozzle while being mixed with innumerable small bubbles in the simultaneously injected water to be sucked.

When the water containing air bubbles collides with rice in the branch pipe, water pressure is applied to the rice and the rice is introduced into the semi-pipe because the bubble buffer function prevents the rice from being worn out to some extent.

Therefore, when the water pressure injected from the nozzle of the water comes into contact with the water containing the bubbles as compared with the case of contacting with the rice, the rate of the decrease of the rice is lowered. Therefore, during the washing of rice, There is an advantage that it can be cleaned.

In addition, since the means for mixing external air is simple in structure, there is little element to cause trouble, and external air is mixed into water only when water is sprayed from the water jetting nozzle. Therefore, So that it can be done more effectively.

Since the present invention is equipped with an air mixing means composed of an injection nozzle for water pushing the rice of the hydraulic pressure machine to the semi-pipe and an air nozzle for punching the air hole, the rice is moved to the semi-pipe by the jetting force of water, It is possible to prevent runaway due to the buffering action of a large number of small bubbles mixed in.

In addition, since the structure of the air introducing means is simple, there is no point of failure, and the outside air is automatically mixed into the water only at the time of spraying water, so there is no need to manage it separately, and there are various effects that can be used more conveniently.
