FIG. 14 is a sectional view taken along the line EE showing the water purification means 70 of FIG. 1, FIG. 15 is a vertical sectional view thereof, in which the water purification means 70 fixes the cylindrical filter 75 and is integral with the power shaft 1 at the center. A rotating upper open cylinder (71), guide means (73) for guiding the discharge of filtered water through the cylinder (71) and guiding the rotation of the cylinder (71), and a cylindrical filter installed coaxially to the cylinder (71). 75 is made. The inner wall of the cylinder (71) and the filter (75) are installed at regular intervals, and the bottom surface of the cylinder (71) having such a gap has a discharge hole (75) communicating with the guide means (73).

Referring to the operation of the present invention configured as described above with the process of the present invention, the present invention is first installed after removing the cover 3 of the hopper 11 of Figure 1 in the sink or food waste discharge path (not shown) do. In this way, when food waste is applied to the hopper 11, power is supplied (it is not shown since it is operated by a power switch or the like) to drive the motor 81. The power of the motor 81 is applied to the power shaft 1 through the pulley belt and the pulley 82, thereby rotating the rotating plate 15 as shown in Figs. 2 and 3 integrally with the power shaft (1). Since the projection 17 is protruded on the rotating plate 15 and the guide rod 14 is in contact with the bottom surface of the rotating plate 15, the projection 17 integrally formed with the rotating plate 14 is guided when the rotating plate 15 rotates. The end of the rod 14 is pushed, and thus the push plate 13 moves downward as the arrow moves up and down, accumulated in the hopper. This is because the spring 19 is a pull spring and normally pulls up the push plate 13, and then the protrusion 17 descends by pushing the guide rod 14 (first process).

The downwardly conveyed debris is transferred to the impurity treatment means 20 as shown in Figs. 3 and 4, while the ring 21 rotates integrally with the power shaft 1, for example, a bulky solid member such as a bottle cap. Push in integral with the push lever (25). At this time, since the ring 21 forms an arc and the push lever 25 is inclined in the direction of rotation, the bottle cap is pushed to collect on the side wall of the housing 2. Therefore, it can be easily collected later. In addition, the ring 21 rotates on the perforated plate 23 so that the food waste is naturally pushed into the hole 22. At this time, the end of the ring 21 has a fixing groove 27 and the fixing groove 27 is coupled to the fixing lever 18 for fixing the blade 16, so that the blade 16 with the rotation of the ring 21 hopper Sweep the residue accumulated in (11) to clean the inner wall of the hopper (11) to improve hygiene. In this case, the blade 16 may exemplify a function and a structure of a window brush of the vehicle (second process).

When the solid impurities such as bottle caps are separated in the impurity treatment means 20, the food waste is pulverized through FIGS. 1, 6, and 7. That is, since the rotary stirring vane 33 is installed on the power shaft 1, the food waste that has passed through the impurity treatment means 20 is transferred by the rotary stirring vane 33 by the screw bone of the fixed screw part 31. As a result, large pieces of food waste are crushed. This is because the conveying path is narrow but the rotary stirring blade 33 continues to supply food waste to receive pressure (third process).

The ground debris is mixed with each other through the mixing means 40 of FIGS. 8 and 9. That is, since the second projection member 42 integrated with the power shaft 1 is provided at a predetermined height interval on the mutually leading end with the first projection member 41 integrated with the housing 2, the falling residue Mix them together. This is because the first projection member 41 is fixed, and the second projection member 42 rotates to mix naturally. In this case, it is preferable that each of the protrusion members 41 and 42 is radially formed as shown in FIG. 9 to perform a mixing function and to reduce the load. In addition, the present invention, if necessary, as shown in FIG. 10, it is preferable to perform a cutter function while the first and second protrusion members 41 ′ and 42 ′ are in contact with each other up and down. This is for easy cutting (step 4).

Subsequently, the mixed debris is transferred to the compression dewatering means 50 of FIGS. 11 and 12, and is compressed and dehydrated through the center screw portion 51. At this time, the inner wall of the cylindrical portion 53 surrounding the central screw portion 51 forms the uneven portion 54. Therefore, food waste is applied to the center screw portion 51 in the form of a wave to double the compression function. In addition, since the screw bone constituting the screw 57 of the central screw portion 51 has a porous portion 59, water is discharged through the porous portion 59, which descends on the cylindrical shaft 55 through the passage 58. (Step 5)

The dehydrated debris is discharged to the discharging means 60. When the discharge means 60 fills the space 65, the weight sensor 64 recognizes this and activates the door opening means 63. Then, the pull means 61, which interlocks with the door 62, pushes the residue to push the space 65 clean. In this case, the present invention can minimize the volume by completely drying by operating a drying means (not shown, but can be easily implemented by an electric heater, etc.) if necessary (sixth step).

Meanwhile, the dehydrated water is transferred to the water purification means 70 of FIGS. 14 and 15. Here, since the cylindrical filter 75 rotates integrally with the cylinder 71 and is purified by centrifugal separation, water is purified and gathered into the space between the inner wall of the cylinder 71 and the cylindrical filter 75 and discharged into the discharge hole 75. do. On the other hand, because it is purified by centrifugal separation, residues accumulate in the internal space, and if it is periodically washed and separated, the life of reuse is extended. The discharged water is discharged through the guide means (73). In the present invention, since the cylindrical filter 75 forms a structure in which several unit filters are connected to each other as shown in FIG. 14, foreign matters in the water are sufficiently filtered and rotated in conjunction with the power shaft 1 so that the filter is in contact with each other. The area is increased, so that even oily residues can be easily purified (step 7). After using the apparatus of the present invention as described above, the durability is improved by installing the spray nozzle in any location of the apparatus to wash the inside.

As described above, the present invention can easily lower the food waste by the shaking action of the food waste supply means, and impurity is pre-filtered by the impurity treatment means, thereby preventing damage to the device, and grinding and mixing before performing the compression dehydration function. It has high dehydration efficiency because it functions, and it is easy to collect because debris is discharged in a dehydrated state when it is a certain amount.Dehydrated water part is filtered by passing through the filter, especially by rotating the filter to increase the filter contact area per unit time. Residue etc. can also be filtered. In addition, since the pulverization and filtration water purification function is integrally formed, it is possible to reduce the volume of the housing, thereby making food waste dehydrated in a general restaurant or at home, thereby reducing waste weight and sanitizing and filtration of the discharged water to protect nature. Can contribute to
