Description

Cyclone air bubble using rice washer

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a semi-automatic machine used for washing cereals, and more particularly, to a cyclone air-blowing machine for continuous feeding of air bubbles and a cyclone system.

In general, semi-cylinders are known as hydraulic semi-cylinders for washing rice with hydraulic pressure, electric semi-cylinders using electric rotating wings, and air-type semi-cylinders for air cleaning. It is difficult to discharge rice balls after washing, and there is a risk of exposure of safety accidents due to rotating blades, and pneumatic semi-cylinders have limitations in increasing cleaning power.

As a background of the present invention, Korean Patent Registration No. 10-1390271, a drum semi-machine has been proposed. A semi-machine main body which is opened at an upper portion and is provided so as to be cleaned by inputting rice and water; A cover which is openably and closably coupled to an upper portion of the main body; A rotary drum rotatably coupled to the inside of the machine body, the rotary drum being provided to generate a vortex when washing rice; And at least one friction generating unit provided on a bottom surface of the drum to generate friction between rice and water when vortex due to rotation of the rotary drum is generated .

This results in a frictional force between the rice and the water in the washing container when washing the rice, thereby obtaining a washing action so that the nutrients are not lost. However, in the background art, when the rotation speed of the rotary drum is increased in order to increase the cleaning power, the frictional force with the friction generating part is increased and the rice grain is broken.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the embodiments shown in the accompanying drawings, but the present invention is not limited thereto.

As shown in FIG. 1, a washing water supply pump 12 connected to raw water and discharging wash water is provided.

A semi-nozzle 14 is connected to the discharge port side of the wash water supply pump 12. At this time, the semi-nozzle 14 may be directly connected to the raw water having the pressure source without using the washing water supply pump 12. [ The semi-nozzle 14 has a front end orifice 14a and a back end orifice 14b that increase the speed of the wash water and reduce the pressure. The front end orifice 14a and the rear end orifice 14b are portions where the diameter of the semi-nozzle 14 is relatively reduced.

Thus, the semi-nozzle 14 increases the speed of the wash water fed by the wash water supply pump 12 from the front end orifice 14a and the rear end orifice 14b, respectively, whose diameter is reduced, and the pressure drop (vacuum vacuum pressure) .

Semicircular three-way valve 16 for selecting either cleaning or recovery is connected to the outlet of semi-nozzle 14. The semi-turn-off three-way valve 16 selects the outlet of either the first outlet 161 or the second outlet 162 depending on the switching position.

The cyclone machine body 20 is connected to the first outlet 161 of the semi- The cyclone body 20 is connected to the first outlet 161 of the semi-reciprocating valve 16 and the outlet 202 is connected to the front end orifice of the semi-nozzle 14, (14a). Accordingly, the cyclone semi- main body 20 is supplied with the washing water having passed through the front end orifice 14a to wash the rice in the form of a whirl, separates the rice flour and wash water by the specific gravity difference, Into the front end orifice (14a) of the piston (14) and float the mixed suspension in the direction of arrow (Z). The cyclone semi-machine body 20 has a cylindrical shape and a lower conical shape. The cyclone machine main body 20 has an openable / closable main cover 22 for filling rice.

Side wicker recovery collection basin 30 is provided vertically below the other of the three-way valves 16 on the second outlet 162 side. The detergent recovery drawstring 30 is made in a net shape so that water can be drained. The washcoat collection sinker (30) recovers the washed rice balls from the cyclone machine body (20).

An air filter (50) is installed to inject sterilizing air bubbles into the cyclone machine body (20). The air filter 50 is connected to the front end orifice 14a of the semi-nozzle 14 through a channel.

The air filter 50 includes a filter housing 51 having an air inlet 51a and an air outlet 51b as shown in FIG. 4, and two or more filter chambers 52 inside the filter housing 51 A chamber partition wall 53 communicating with the chamber 52 at the same time, and a sterilizing filter medium 54 filled in each chamber 52 to sterilize the air introduced into the chamber. The sterilizing filter medium 54 may be ceramic balls, diatomaceous earth, bio-rings, loess, volcanic stone, and the like.

Therefore, when the washing water is supplied to the semi-nozzle 14 as shown in FIG. 2, a suction force is generated inside the filter housing 51 due to the pressure drop generated in the front end orifice 14a, Sterilized by passing through the sterilizing filter medium 54 in the washing tub 52 and then supplied to the semi-nozzle 14 as air bubbles. The air bubbles are supplied into the cyclonic machine body 20 through the semi-rotary three-way valve 16 in the form of air bubbles to serve as buffering elements for preventing the rice balls from colliding with each other and breaking. In addition, a sound wave is generated by raising the flow rate in the semi-nozzle 14, and this sound wave functions as a cleaning power enhancing function for washing the rice grain that exits the outlet 202.

Preferably, the pipe connecting the air filter 50 and the semi-nozzle 14 is provided with a check valve 90 for preventing the backwash of the supply wash water.

3, a wastewater detection sensor 60 is provided to detect the amount of rice that is washed and recovered and filled in the wastewater recovery drainage basket 30. The scrubber detection sensor 60 is installed at the end of a conduit connected to the second outlet side 162 of the semi- And a detection signal of a small amount detected by the scrubber detection sensor 60 is inputted to the control panel 80. [

The control panel 80 determines whether the signal sensed by the scrubbing detection sensor 60 is received and opens and closes the inflow water supply control valve 70. The incoming water supply control valve 70 is connected to the outlet side of the wash water supply pump 12. In addition, the control panel 80 has an operation time controller 82 (e.g., a timer) that can control the operation time required for the semi. The control panel 80 is provided with a washing end alarm 83 for comparing the input value and the set value measured by the wastewater detection sensor 60 with the set value and generating a buzzer sound when the semi-volume reaches the set value . The control panel 80 stores the battery therein, so that no additional electrical work is required.

The reference numeral '34' is an 'opening and closing valve'.

The operation of the semiconductor device constructed as described above will be described with reference to the control flow chart of FIG.

First, as shown in FIG. 2, an appropriate amount of rice to be washed is placed in the cyclone machine main body 20.

Then, the cleaning time is set through the operation time controller 82 of the control panel 80 (S10).

Then, the control panel 80 judges the ON / OFF signal operation for operating the wash water supply pump 12 (S11). The wash water supply pump 12 is driven (S12), the inflow water supply control valve 70 is opened (S13), the semi-turn three-way valve 16 is switched to the first outlet 161 Is connected to the inlet 201 of the cyclone machine body 20.

Accordingly, the washing water is supplied to the cyclone semi- main body 20 through the semi-nozzles 12 by the driving of the washing water supply pump 12, . That is, rice washing (S14) is performed.

As shown in FIG. 2, the flow rate of the washing water is increased and the pressure is lowered in the front end orifice 14a of the semi-nozzle 14, so that the rice flour is discharged little by little through the outlet 202 and recovered through the inlet 201, And is then recycled into the main body 20.

At the same time, the sterilization air is introduced (S15) by the generation of the suction force due to the pressure drop at the front end orifice 14a. That is, outside air flows through the air inlet 51a, passes through the sterilizing filter medium 54 in the air filter 50, and then flows into the semi-nozzle 14. At this time, the inflow air is in the form of air bubbles, which prevents the rice balls from colliding with each other. In addition, a sound wave due to the high-speed flow is generated in the front end orifice 14a, thereby improving the function of washing the rice. At this time, the flow of the backward flow to the air filter (50) is prevented by the backflow prevention valve (90), and the sterilizing function is continuously maintained.

Therefore, the rice ball, the washing water, the foam and the foreign substance are mixed together by the rice washing process (S14) and the sterilization air feeding process (S15), and the raw water flows into the cyclone machine main body 20 through the semi- The washing and sterilization of the rice grain occurs. In addition, as shown in FIG. 3, light foreign matter or bubbles float upward in the inside of the main body 20 due to the specific gravity difference.

Thus, the washing process and the sterilization process of the rice flour are continuously performed until the set time is completed (S23).

Next, when the setting time is completed, the semi-return valve (16) for semi-turn reception is opened to the side of the wastewater collection counterflow (30) and semi-recovery (S17) is performed in which the washed rice grain is recovered.

That is, the rice flour that has been washed in the cyclone machine main body 20 is taken out through the outlet 202 and collected on the washing water to be collected on the side of the washbasin collection sink 30. At this time, the wash water flowing out from the washcoat collection sink 30 is discharged to the drain hole 200 through the sink holder 32.

At this time, the semi-finished product of the rice flour washed by the scrubber detection sensor 60 is measured (S18), and it is determined whether or not the semi-finished product is stopped to be collected (S19).

The water supply control valve 70 is closed (S20), the washing water supply pump 12 is stopped (S21), and an alarm is generated through the washing end alarm 83 (S22) .

On the other hand, the inlet water supply control valve 70 can appropriately adjust the pressure value measured in real time in the pressure gauge 70 by comparison. It is also possible to make the alarm at the end of the washing in parallel with the lamp.

In the absence of the wash water supply pump 12, the raw water is supplied under the control of the inlet water supply control valve 70.

In the present embodiment, rice was washed, but it is needless to say that the present invention can be used for washing other grains.

The present invention has been described in connection with the case where the washing water supply pump 12 is connected to the raw water to discharge the washing water. However, the present invention is not limited thereto, It is also possible to directly connect to the raw water.

As shown in FIG. 6, a cylindrical partition wall 205 may be further provided in the cyclone machine body 20 to separate floats floating from the washed rice grains. That is, as shown in FIG. 6, no rice balls are supplied to the inner space of the cylindrical partition wall 205, and the rice balls are supplied only between the cylindrical partition wall 205 and the inner wall of the main body 20, It is possible to guide the suspended solids to the inner space of the cylindrical separating partition 205 to float only the suspended solids in the arrow direction Z. Although not shown in FIG. 6, it is preferable that the lower diameter of the cylindrical partition wall 205 is formed to be larger than the upper diameter so that the mixed suspension can float in the direction of arrow Z. FIG.

7, the air filter 50 may include a low-density filter 151, a medium-density filter 152, and a high-density filter 153 whose density gradually increases, have.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art in light of the above teachings. will be. The invention is not limited by these variations and modifications, but is limited only by the claims appended hereto.
