Description

[0001] The present invention relates to a food waste disposer using dry screw and a triangle shaped moving cutter,

The present invention relates to a food waste disposal apparatus, in which a heater is installed in a drying housing, a triangular-shaped transfer cutter is provided on an inner wall surface of the drying housing, a drying screw is installed in the drying housing, and a drying screw is rotated at low speed in both directions So that the portion of the food waste that has been pulverized in the inside of the drying housing is gradually heated and dried along the drying screw, and then the portion of the inner wall of the dry housing which is adhered to the inner wall of the dry housing is torn off by the sharp portion of the feed cutter by reverse rotation, To a food waste disposal apparatus using a dry housing equipped with a transfer cutter of a triangular shape.

As the industry develops and the life becomes richer, the food becomes rich and enriched, and as the food becomes richer, a large amount of food waste is left behind after the meal. This food garbage contains a lot of water, and if it is left at room temperature for a certain time, it is spoiled by microorganisms, causing bad odor and polluting the environment.

Currently, the processing of food wastes that are practically used is collecting and processing the food wastes collected at homes and businesses, but there is also proposed a technique relating to various processing apparatuses for processing food wastes by installing them in homes or businesses .

For example, Korean Patent Application No. 10-0753808 (Patent Document 1) discloses a device for drying a food waste residue, which is filed by the inventor of the present application, and includes a crushing dewatering means installed at the bottom of a sink for crushing and dehydrating food waste, The dry box is presented in a form similar to the grinding and dewatering means and drying means of the present invention described below.

In the above-described Patent Document 1, a plurality of splines arranged in parallel with the central axis and having a rectangular shape are formed in the inside of the drying box, and the splines are connected to the second screw rotating in the inside of the drying box, So that the transfer of the food waste is made easy.

However, the inventor of the present application has found that the above-mentioned Patent Document 1 was directly manufactured and used, and as a result, it was relatively easily pulverized in the drying box, but the food waste sticking to the wall surface of the drying box in the heating process did not fall off easily It is confirmed that the phenomenon of accumulation occurs.

In addition, there is a problem that the sectional shape of the quadrangular pyramid hinders the rotation of the motor, causing a load on the motor, and the spline is easily worn.

In addition, since pulverization is performed without supplying water separately, the food waste is not sufficiently pulverized due to aggregation of the food waste during the pulverization process, and it is discharged in a state exceeding the standard value (1%) of the food waste specified by the Ministry of Agriculture and Forestry, There was also a problem that it was difficult to recycle.

Regarding the supplement of such a problem, a spray nozzle for spraying water into the hopper is disclosed in the "food waste treatment apparatus" (Korea Utility Model Application Utility Model No. 20-0224950, Patent Document 2).

However, in the injection nozzle of Patent Document 2, water is sprayed to clean the internal device, and since a plurality of spray nozzles are arranged at a portion where the screw interval is narrowed, the food garbage is compressed The nozzle can be closed by blocking the inlet of the injection nozzle.

In addition, since the mill is installed after the grinding process, the food garbage such as the one described above can not be crushed and crushed unfavorably.

Among them, it is preferable to be constituted by the constitution described below.

Specifically, it is preferable that the first and second spindle housings 11 and 12 of the pulverizing and dewatering means 10 are detachably coupled to each other, and the spindle screw 13 is inserted into the first and the second spindle housings 11 and 12.

4 and 5, the first spindle housing 11 is connected to the hopper 100 so that the inlet 11i into which the food waste stored in the hopper 100 is inserted is formed in a vertical direction on the upper portion have.

In addition, a plurality of drain holes 11w are formed on the floor.

The middle portion of the first spindle housing 11 has a cylindrical shape in the horizontal direction. On the inner wall surface, at least one feed cutter 11t formed in the horizontal direction is formed. An opening 11a is formed at one end have.

As shown in FIG. 7, the feed cutter 11t is formed in the longitudinal direction of the first spindle housing 11 in the horizontal direction. The feed cutter 11t crushes the food waste pushed and transported by the rotation of the spindle screw 13. That is, the food waste is pushed by the rotation of the spindle screw 13 and is crushed by the feed cutter 11c.

The opening 11a which is the discharge side of the first spindle housing 11 and the second spindle housing 12 which communicates with the inner side become closer to the end side, that is, the direction corresponding to the end side of the spindle screw 13 housed therein And an outlet 12o is formed at the other end thereof.

In addition, the first spindle housing 11 is detachably connected to the first spindle housing 11 by a method such as bolting.

One or more feed cutters 12t are formed in the inner wall of the second spindle housing 12 in the horizontal direction.

The feed cutter 12t has a second spindle housing 12 formed on the inner wall in the longitudinal direction of the spindle housing in the same manner as the feed cutter 11t formed in the first spindle housing 11, The food waste transported by rotation is crushed.

That is, the food waste is pushed by the rotation of the spindle screw 13 and is crushed by the feed cutter 12t. Of course, since the second spindle housing 12 has an inner diameter gradually narrowing toward the discharge port 12o, the transfer cutter 12t is also inclined toward the center of the second spindle housing.

On the inner wall of the discharge port 12o of the second spindle housing 12, at least one crushing cutter 12c having a spiral shape is formed.

The grinding cutter 12c is pushed and transported by the spindle screw 13 to be pressurized and crushed by the interaction of the first spindle housing 11, the second spindle housing 12 and the spindle screw 13, However, the grinding cutter 12c is further formed inside the wall having the discharge port of the second spindle housing so that the grinding cutter can be further crushed.

The spindle screw 13 is installed inside the first spindle housing 11 and the second spindle housing 12.

In addition, a motor (not shown) is connected to one side and is rotatably installed.

The spindle screw 13 has a shape in which the outer diameter gradually decreases toward the discharge port 12o of the second spindle housing and a screw blade 13w is formed on the outer circumferential surface of the spindle screw 13. An end portion of the spindle screw 13c, And a cutter blade 13c is formed.

The spherical groove 13r is formed so that the distance between the screw vanes 13w of the spindle screw 13 is adjusted and the connection between the screw vane 13w and the housing is formed in a arc shape, .

The water supply means 20, the drain trap 30, the deodorizing means 40, and the collection box storage chamber 60 may be further included as components of the present invention.

The water supply means 20 is installed on the upper portion of the hopper 100 to dilute the saline of the food waste by supplying diluted water into the hopper 100.

The food waste to be pressurized and pulverized by the pulverizing / dehydrating means 10 contains a large amount of salt. When the water is pressurized by the pulverizing / dehydrating means 10, the dried food waste discharged therefrom contains a large amount of salt When food waste having such salinity is buried, salinity may leak and contaminate the soil. When the waste is reused as fertilizer, there is a problem that the crops are killed due to salinity.

Accordingly, in order to remove the salt from the food waste treated and dried by the food waste disposal apparatus of the present invention to have an environmental standard value of less than 1%, it is necessary to sufficiently remove the salt from the food waste supplied to the pulverizing / dehydrating means 10 It is to supply more water.

As shown in the figure, the water supply means 20 is installed through the side wall of the hopper and is connected to a water supply such as a water in the kitchen to supply water supplied along the inner wall surface of the hopper 100, So that water is uniformly supplied to the food waste.

The drain trap 30 discharges waste water and odor generated in the process of dewatering and crushing the food waste to the sewage pipe. As shown in FIGS. 1 and 2, one side of the drain trap 30 is connected to the crushing / dehydrating means 10 A pulverized water pipe 30c and an exhaust pipe 50p having one side connected to the drying means 50 and a blower 50b disposed in the middle are connected to one side of the pipe and the end is connected to the sewer pipe.

That is, the discharge water discharged from the pulverizing and dewatering means 10 is supplied and discharged through the pulverizing and draining pipe 30c and the exhaust gas containing moisture discharged from the drying means 50 is supplied through the discharge pipe 50p, .

The blower 50b in the middle of the exhaust pipe 50p allows the drain water and the exhaust gas to be discharged more smoothly.

The drain trap 30 is provided with a U-trap 30u for preventing backflow of the odor in the middle of the pipe.

1, the deodorization means 40 is connected to one side of the end side pipe of the drain trap 30 and is installed on the upper side thereof. The deodorization means 40 is composed of a filtration filter containing activated carbon, ) In the exhaust gas.

The hopper 100 is connected to the drain trap 30 as shown in FIG. 1 so that the gas discharged from the drying means 50 during operation of the blower 50b flows into the hopper 100, The odor is forcibly introduced into the drain trap 30 through the hopper drain pipe 30h, and the deodorization is smoothly performed.

At this time, when the sewage pipe is clogged and a static pressure is applied, the malodorous component flows into the deodorizing means 40 in which the activated carbon is contained, and the purification treatment is performed.

On the other hand, the collection bin storage chamber 60 is provided below the drying means 50, and is capable of collecting dry food waste discharged from the drying means 50.

The food waste which is pressurized and pulverized and discharged by the pulverizing and dewatering means 10 is discharged through the discharge port 12o formed at one end of the second spindle housing 12 as described above, However, since moisture is left in the discharged food waste, it is preferable that the food waste is discharged in a completely dried state because the odor may be generated in the space where the food waste disposal apparatus is installed while the moisture is dried. To this end, (50).

8 and 9, the drying means 50 includes a drying screw 52 inside the drying housing 51 and an inner peripheral surface of the drying housing 51 is disposed inside the drying housing 51 And a discharge cap 54 for discharging the dried food waste is formed in the discharge port 51o of the drying housing 51 by forming a plurality of discharge holes 54h.

The drying housing 51 is shown in detail in Figures 8-10, 12-14.

10, a circular wall surface 51f having a vertical direction at one end thereof is formed, and an outlet 51o is opened at the other end thereof. The outlet port 51o is formed at one end and the other end There is formed a body portion 51e having a central axis in the horizontal direction and assuming a cylindrical inner shape having a horizontally laid shape.

At this time, on the circular wall surface 51f, a plurality of side wall cutters 51s projecting in a straight line from the center axis toward the outer peripheral side end side are radially formed.

8 and 9, a gas discharge port 51g connected to the drain trap 30 is formed at the upper center of the body portion 51e to discharge dry gas generated in the inside of the body portion 51e And an inlet 51i connected to the discharge port 12o of the second spindle housing 12 is formed in a horizontal direction on one side of the upper portion so that the powdered and dehydrated food waste is introduced from the pulverizing and dewatering means 10 have.

A plurality of feed cutters 51t are formed on the inner circumferential surface of the body portion 51e along the longitudinal direction of the body portion 51e along the direction of the central axis.

The feed cutter 51t basically grinds the food waste pushed and transported by the rotation of the drying screw 52 as in Patent Document 1 filed by the inventor of the present application.

That is, as the food wastes are pushed by the rotation of the feed vane 52w of the drying screw 52, the feed vane 52w and the feed cutter 51c interact with each other and the food waste is crushed.

However, in the present invention, the feed cutter 51t is further improved than the conventional one.

Specifically, in the present invention, the feed cutter 51t has a triangular cross-sectional shape, and an internal angle between the one side 51a and the inner circumferential surface of the body 51e is 90 ° or more and less than 180 °, (51a) is formed to be sharp from the inner circumferential surface of the body portion (51e), and the other side (51b) is formed to have a gentle inclination.

This configuration is engaged with the shape of the conveying vane 52w of the drying screw 52 to be described later so that when the conveying vane 52w is coupled in the form of a right-handed screw toward the discharge port 51o, the other side 51b is viewed from the front The food garbage 200 is moved on the other side 51b inclined obliquely when the food garbage 200 rotates and moves toward the discharge port 51o as shown in Fig. 13 by being formed on one side 51a. The food waste 200 traveling on the inner circumferential surface 51h is moved along the side surface 51a having a steep slope in the process of rotating the drying screw 52 in the opposite direction and rotating the food waste into the drying housing 51, So that crushing can be easily performed.

When the drying screw 52 rotates toward the discharge port 51o side, it rotates at a low speed as described later. At this time, the moisture is evaporated while being heated by the heater 53, and the remaining food waste is transferred to the drying housing 51, As the water is evaporated along with the evaporation of moisture, it is generated on the wall surface of the drying housing 51 as if it is caused by evaporation of water when calendering is made in the cauldron. When the water is evaporated, So that the pulverization can be more easily performed by the grinding wheel 51b.

The other side 51b of the feed cutter 51t gradually increases in length from one end side toward the discharge port 51o as the inner angle between the other side edge 51b and the inner peripheral surface of the body portion 51e decreases toward the discharge port 51o And is configured to gradually increase.

That is, when the cross section is taken as a reference, the inclination of the other side 51b becomes larger as the inclination angle increases from the inside to the outside.

14, the angle formed by the bottom surface of the other side 51b gradually increases from the rear to the front. As the drying screw 52 rotates in the forward direction from the rear to the front, the food garbage So that it is more strongly adhered to the wall surface of the drying housing 51, thereby increasing the drying efficiency.

The drying screw 52 is installed in the drying housing 51 and is provided with a rotating shaft 52a. The rotating shaft 52a is rotated in both directions, protruding outside the circular wall surface of the drying housing 51, A rotation motor 52b is connected.

At this time, it is preferable that the rotation motor 52b shown in FIG. 12 rotates at a low speed of rpm 0.1 to 30 at a forward rotation and at a high speed of rpm 60 to 3,000 at a reverse rotation.

The feed vane 52w is connected to the rotation shaft 52a in a spiral manner and the feed vane 52w has a circular shape in which the food waste in the dry housing 51 is circular And advances toward the wall surface 51f side and toward the discharge port 51o side.

At this time, when the food waste rotates in the direction of advancing toward the discharge port 51o, the drying screw 52 rotates in the direction toward the one side 51a from the other side 51b of the transfer cutter 51t, To the wall surface 51f side of the feed cutter 51t in the direction of the other side 51b of the feed cutter 51t.

Particularly, the conveying vane 52w is formed such that the distance between the conveying vanes 52w gradually decreases toward the discharge port 51o.

The gap between the conveying vanes 52w is narrowed toward the front side in order to increase the drying efficiency by increasing the pressure of the food waste toward the discharge port side.

In particular, since the inclination angle of the other side 51b of the feed cutter 51t is increased toward the front side, the drying efficiency is increased by increasing the pressure in forward rotation from the rear side toward the front side, .

This is because the moisture content of the food waste gradually decreases due to the pressing and heating while moving from the rear side to the front side and when the drying housing 51 and the drying screw 52 are the same in the front and rear structures, The pressure of the drying wing 52w of the drying screw 52 is narrowed and the pressure is increased so that the pressure is fully applied despite the reduced volume in the forward movement, The high inclination angle of the other side 51b makes it more likely to occur in the inner circumferential surface of the drying housing 51 so that the grinding can be smoothly performed even in the backward movement despite the reduced volume.

In addition, as the interval between the conveying blades 52w becomes larger at the time of the rearward movement, the pressurized and pulverized food waste can be easily released and discharged to the discharge port 51o at the time of re-advancing.

The drying screw 52 is further provided with a breaking cutter blade 52c having a larger diameter than the diameter of the feed vane 52w at the tip of the rotating shaft 52a on the side of the discharge port 51o.

The pulverizing cutter blade 52c allows the food waste pulverized by the drying screw 52 to be finely pulverized immediately before being discharged through the discharge hole 54h of the discharge cap 54, 51t) or having an interval of about 1 to 10 mm, and is formed to be larger than the conveying vane 52w.

In addition, in addition to the above-described configuration, as shown in FIG. 15, a plurality of sidewall cutters (not shown) formed in the drying housing 51 are provided to easily drop the food waste attached to the circular wall surface 51f 51s have a triangular cross-sectional shape in which one side 51c and the other side 51d adjacent to each other are formed with the circular wall surface 51f as a base, and a cross section between the other side 51d and the circular wall surface 51f It is preferable that the other side edge 51d is formed to be sharp from the circular wall face 51f and the one side face 51c is formed to have a gentle slope.

At this time, one side 51c is formed at a position in which the food waste contacts the rotation direction of the drying screw 52, which moves backward from the discharge port 51o side toward the circular wall surface 51f, before the other side 51d, It is particularly preferable that the other lateral side 51d is formed at a position in contact with the rotational direction of the drying screw 52 for advancing the food waste toward the discharge port 51o side before the one side 51c.

This configuration is such that the rear end portion of the feed vane 52w is formed to correspond to the forward and backward rotation of the drying screw 52 by the shape of the side wall cutter 51s formed on the circular wall surface 51f, And is pressed against the circular wall surface 51f at the time of rotation. In this case, the slope is made to be closely contacted along the inclination of the oblique one side face 51c, and when the forward direction is rotated, the grinding is performed by the abrupt inclination of the other side face 51d .

In addition, it is preferable that a marble coating layer using a raw material such as acetal is formed on the inner wall surface of the drying housing 51.

This is because when the moisture of the food waste heated by the heat of the heater 53 is heated and dried, the food waste adhering to the inner wall surface easily occurs on the bottom surface.

12, the boundary line between the one side 51a of the feed cutter 51t and the inner circumferential surface of the drying housing 51 is parallel to the center axis a of the drying housing 51, The boundary line between the other side 51b and the inner circumferential surface of the drying housing 51 may be inclined with respect to the center axis of the drying housing 51.

When the drying screw 52 rotates in the forward direction, the drying screw 52 is easily slid and pushed along an oblique slope. When the drying screw 52 is rotated in the backward direction, the feeding vane 52w of the drying screw 52 is moved to the one side 51a So that the food waste adhering to the inner wall surface can easily be desorbed.

The food garbage disposer of the present invention configured as described above is characterized in that the drying screw 52 alternately rotates in the forward direction and the reverse direction within the drying housing 51 and the forward rotation and the reverse rotation are alternately performed, The other side 51b of the feed cutter 51t and the other side 51d of the sidewall cutter 51s of the circular wall surface 51f are formed in the inside of the body 51e When the food waste is rotated in the reverse direction, the one side 51c of the feed cutter 51t and the side 51c of the side wall cutter 51s of the circular wall face 51f are crushed Is finally repeatedly crushed by the crushing cutter blade 52c and then discharged through the discharge hole 54h of the discharge cap 54. [

In this process, the food waste in the body portion 51e is continuously evaporated by the distance between the feed blades 52w of the drying screw 52 by engaging with the shape of the feed cutter 51t and the side wall cutter 51s, The drying efficiency is high, and the remaining amount of food waste in the drying housing 51 can be minimized.

The present invention can be installed and used at home, but more preferably, it is installed in a restaurant or the like where a large amount of food waste is discharged and used.
