Description

Agitator for food waste treatment apparatus

This specification relates to a food waste processor. To be more specific, it is designed to uniformly stir food waste discharged from homes and put into a stirring container together with microorganisms, and to increase the reduction rate of food waste due to the cultivation of microorganisms. This relates to a stirring device for a food waste processor.

Unless otherwise indicated herein, the material described in this section is not prior art to the claims of this application, and is not admitted to be prior art by inclusion in this section.

In general, food waste discharged from households varies seasonally, but a large amount of 30 to 50% of the total waste is discharged and is disposed of by landfill, incineration, or composting methods.

Recently, with the implementation of the volume-based waste fee system, food waste disposal devices used in general homes and restaurants to reduce food waste are designed to remove moisture from food waste through processes such as drying and deodorization, and at the same time reduce the volume, thereby reducing the amount of emissions. I'm doing it.

This food waste disposal device is composed of a main body, a drying furnace that accommodates food waste, a hot air blower that circulates hot air inside the main body, an exhaust device that discharges the circulated air, and a deodorizing means that purifies and discharges the air in the exhaust device. , some food waste treatment devices are equipped with agitators that can mix food waste.

Most of these food waste treatment devices only force hot air to circulate to evaporate the moisture in the food waste, so the efficiency of food waste treatment is low, and the scale of the equipment is also large, making it uneconomical in terms of operation and handling.

The food waste disposal device according to the prior art shown in FIG. 1 includes a drum-shaped body (1) with a U-shaped cross-section in which a door (not shown) is mounted on the top to be openable and closed, and accommodating food waste introduced through the opening. and,

A drive motor (2) disposed on the outer lower part of the main body (1),

A drive chain (5) installed on the drive gear (3) (sproket) formed on the rotation axis of the drive motor (2) and the driven gear (4) (sproket) mounted on the outer surface of the main body (1),

A rotating shaft (6) rotatably installed through the lower part of the main body (1),

A connecting rod (7a) is spaced longitudinally on the rotating shaft (6) and fixed at an arbitrary angle in the circumferential direction, and is fixed to the rotating shaft (6) by a screw to agitate and ferment the input ordinary food waste and microorganisms. and a rod-shaped blade 7 (as an example, made of a metal material) consisting of a mixer plate 7b formed on the outer end of the connecting rod 7a,

It is connected to both sides of the rotating shaft (6) inside the main body (1) and is equipped with inner flanges (11, 12) to prevent foreign substances such as food waste from penetrating into the bearing (8) during stirring. do.

In the drawing, reference numeral 9 is a side plate mounted on the left and right outer sides of the main body (1), and 10 is connected to the drive motor (2) and is used to discharge bad odors generated when processing food waste inside the main body (1) to the outside. 13 is an oil seal mounted on both ends of the rotating shaft (6).

In the food waste treatment device as described above, food waste or microorganisms located between the blades 7 and adjacent rod-shaped blades 7 mounted spaced apart on the rotating shaft 6 are not smoothly stirred (i.e. In the blind area between the adjacent blades 7 and the blades 7, only food waste or microorganisms flow, and they do not move to the left or right (i.e., they spin around in place), so they are not stirred smoothly, resulting in stagnation. phenomenon occurs), and food waste or microorganisms often stick to the inner bottom surface of the main body (1) and settle.

As a result, the food waste reduction rate by the food waste treatment device significantly decreases, and when processing food waste inside the main body 1, the microbial moisture content increases, causing the microorganisms to die, resulting in a shortened service life.

In addition, when the drive motor (2) is driven, the screw that secures the rod-shaped blade (7) to the rotary shaft (6) is loosened due to repeated rotation of the rotation shaft (6) in the forward and reverse direction, which causes the fixed state of the blade (7) to change. There are problems that require frequent inspection and confirmation.

In addition, the bearings 8 that support both ends of the rotating shaft 6 are made of metal bearings, so the blade 7 is repeatedly rotated in the forward and reverse directions, or noise is generated due to damage to the bearings 8. , there is a problem of suffering from noise due to the operation of the food waste disposer usually used in the kitchen.

Therefore, there is an urgent need for the development of a food waste treatment device that can efficiently and economically treat food waste.

A food waste disposal device is registered and announced in the Republic of Korea Patent Publication No. 10-1705997 (2017.2.10).

The embodiment of the present specification increases the food waste reduction rate through efficient agitation of food waste and microorganisms introduced into the mixing tank, but also increases the food waste reduction rate through movement and flow of food waste and microorganisms to the left or right when the spiral blade rotates. It is related to a stirring device for a food waste processor that allows the culture to proceed uniformly and activate it.

The embodiment of the present specification is a stirring device for a food waste processor that reduces noise due to bearing damage by eliminating the bearing that rotatably supports the rotating shaft due to improved structure of the spiral blade that agitates food waste and microorganisms. It is related to the device.

The embodiment of the present specification relates to a stirring device for a food waste processor that does not require the use of separate fastening members such as screws by fitting the boss portion of the spiral blade with a concave-convex connection to the rotating shaft penetrating the main body.

It is formed by a boss part coupled by a coupling groove formed to correspond to the rotation axis, and a wing part helically protruding on an outer surface of the boss part, and includes a plurality of spiral blades,

When the drive motor is driven in the forward or reverse direction, the spiral blade rotates in the forward or reverse direction inside the main body, causing food waste and microorganisms to flow inside the main body in the direction of rotation of the spiral blade, and moving to the left or right. A stirring device for a food waste disposer is provided, characterized in that it can be repeatedly moved and agitated.

According to another embodiment of the present specification to achieve the above and other purposes of the present specification,

a drive motor mounted on the outside of the main body and driven in one direction by applying a control signal from the outside;

a rotation shaft that penetrates the main body to be rotated by the drive motor, has both ends rotatably supported on out flanges respectively mounted on outer surfaces of the main body, and has an outer periphery formed in a polygonal shape;

It is formed to include a boss part coupled by a coupling groove formed to correspond to the rotation axis and a wing part spirally protruding on an outer surface of the boss part, and is mounted on the rotation axis to be spaced apart in the longitudinal direction, and when rotated, the food waste is disposed of. and a pair of first and third spiral blades for rotating and agitating the microorganisms;

It is formed to include a boss part coupled by a coupling groove formed to correspond to the rotation axis and a wing part helically protruding on an outer surface of the boss part, and is alternately mounted on the rotation axis with the first and third spiral blades. , a pair of second and fourth spiral blades for flowing and agitating food waste and microorganisms inside the main body when rotating,

When the first, second, third and fourth spiral blades are rotated by driving the drive motor, food waste and microorganisms are removed from the inside of the main body by the rotation of the first and fourth spiral blades mounted on both ends of the rotation shaft. It is stirred by repeatedly moving from the edge to the center, and food waste and microorganisms can be repeatedly moved from the center inside the main body to the edge by rotating the second and third spiral blades mounted on the middle side of the rotating shaft. A stirring device for a food waste processor is provided.

According to a more preferred embodiment, an oil seal is mounted on both sides of the rotating shaft so as to be in close contact with the inner surface of the out flange and prevents food waste and microorganisms stirred inside the main body from penetrating into the coupling gap between the out flange and the rotating shaft; It is characterized by being further provided.

The out flange is characterized in that it is formed of a POM material or an engineering plastic material with lubricity and durability to rotatably support the rotating shaft.

The stirring device for a food waste processor according to an embodiment of the present specification having the above-described configuration has the following advantages.

The food waste reduction rate is increased through efficient agitation of food waste and microorganisms put into the main body's mixing tank, and when the spiral blade rotates, microbial culture is achieved through repeated movement and flow of food waste and microorganisms to the left or right. It progresses uniformly, making it possible to control temperature and humidity inside the stirring tank, thereby extending the useful life of microorganisms.

In addition, by improving the spiral blade structure that agitates food waste and microorganisms, the bearing supporting the rotating shaft is eliminated, and the number of flanges made of POM material with excellent lubrication that supports the rotating shaft is reduced, reducing production costs and eliminating the need for conventional metal bearings. By reducing noise caused by damage, it is possible to maintain quietness when using the food waste disposer in the kitchen.

In addition, by fitting the boss portion of the spiral blade to the rotating shaft penetrating the main body in a concavo-convex joint, the use of separate fastening members such as screws becomes unnecessary, thereby improving the workability of assembling the blade to the rotating shaft and replacing the conventional bar-shaped blade. The process of checking whether the screw that fixed the to the rotating shaft is loosened becomes unnecessary.

Hereinafter, a stirring device for a food waste processor according to a preferred embodiment of the present specification will be described in detail with reference to the accompanying drawings.

Referring to FIGS. 2 to 4, the stirring device for the food waste processor according to an embodiment of the present specification is

It is applied to a stirring device for a food waste processor to agitate and process food waste decomposed by microorganisms by stirring it by using a stirrer, which is put into the stirring tank of the main body, which has a door that can be opened and closed at the top,

A driving motor 20 mounted on the outside of the main body 1 and driven in the forward and reverse directions (clockwise, counterclockwise) by applying a control signal from the outside (control unit);

A rotation axis ( 40);

It is formed to include a boss portion 60 coupled by a coupling groove 50 formed to correspond to the rotation axis 40, and a wing portion 70 that protrudes in a spiral shape on the outer surface of the boss portion 60, and includes a plurality of wings. It is provided with a spiral blade 80 (as an example, three are shown to facilitate understanding, but is not intended to be limited thereto),

When the drive motor 20 is driven in the forward or reverse direction, food waste and microorganisms are removed from the stirring container 1a of the main body 1 by rotation of the spiral blade 80 in the forward or reverse direction. It is characterized by allowing food waste and microorganisms to be uniformly stirred by flowing in one direction and repeatedly moving in the left or right direction at the same time.

According to a more preferred embodiment, as shown in Figures 2 and 3, it is mounted on both sides of the rotating shaft 40 so as to be in close contact with the inner surface of the above-described out flange 30, and the stirring container 1a of the main body 1 It is characterized by being provided with a conventional oil seal (90) to prevent food waste and microorganisms stirred inside from penetrating into the coupling gap between the out flange (30) and the rotating shaft (40).

The above-mentioned out flange 30 is characterized in that it is formed of a common POM material or an engineering plastic material having lubricity and durability to rotatably support the rotating shaft 40.

For this reason, instead of using a normal bearing that rotatably supports the rotating shaft 40 penetrating the main body 1, a normal POM having lubricity and durability is used on both ends of the rotating shaft 40 exposed to the outside of the main body 1. It is rotatably supported by an out flange 30 made of material or engineering plastic material.

Accordingly, by changing the shape (or structure) of the spiral blade 80 that is unevenly coupled to the rotation shaft 40, the bearing that rotatably supports the rotation shaft 6 on which the conventional rod-shaped blade 7 is fixed is replaced. Since the rotating shaft 40 can be rotatably supported by the out flange 30, noise defects caused by damage to metal bearings can be reduced, and raw costs can be reduced.

Hereinafter, a stirring device for a food waste processor according to an embodiment of the present specification will be described with reference to the accompanying drawings.

2 to 4, a driving motor 20 that is mounted on the lower part of the main body 1 where the stirring container 1a, which has a U-shaped cross section, is installed and can be driven in both directions, and a driving motor 20 The rotation shaft ( 40) is rotated.

That is, the rotation shaft 40 is repeatedly rotated in a random cycle in the forward (clockwise) or reverse (counterclockwise) direction according to the rotation direction of the drive motor 20, which is driven in both directions by applying a control signal from the outside. You can do it.

As described above, food waste containing moisture and ordinary microorganisms discharged from homes, etc. are put into the stirring container (1a) of the main body (1), and then a spiral blade is mounted on the rotating shaft (40) penetrating the main body (1). By repeatedly rotating (80) in the forward or reverse direction at random cycles, food waste and microorganisms can be uniformly stirred inside the stirring tank (1a) without stagnation (see FIG. 4).

As a result, the spiral blade 80 rotates in the forward or reverse direction inside the stirring tank 1a, thereby causing food waste and microorganisms to flow around the rotation axis 40 by the spiral blade 80 and at the same time moving in the left or right direction. By moving it in one direction, the food waste reduction rate can be increased through efficient stirring of the food waste and microorganisms introduced into the stirring container 1a of the main body 1.

Therefore, when rotating the rotating shaft 40 inside the stirring container 1a, food waste and microorganisms are flowed by the spiral blade 80, and at the same time, the left or right side is changed depending on the shape (structure) of the spiral blade 80. By repeatedly moving in this direction, stagnation of food waste and microorganisms is prevented inside the stirring tank (1a). As a result, the culture of microorganisms progresses uniformly inside the stirring tank (1a), making it possible to control temperature and humidity, thereby extending the useful life of microorganisms.

On the other hand, in the conventional stirring device with bar-shaped blades (see FIG. 1), food waste or microorganisms only flow around the rotation axis (6) in the blind area between the adjacent blades (7). This causes the so-called stagnation phenomenon, in which the liquid is not stirred smoothly, as it does not move to the left or right, causing the so-called stagnation phenomenon to occur.

As a result, the food waste reduction rate by the food waste treatment device significantly decreases, and when processing food waste inside the main body 1, the microbial moisture content increases, causing the microorganisms to die, resulting in a shortened service life.

Meanwhile, a coupling groove 50 formed on the boss portion 60 of the spiral blade 80 corresponds to the rotation axis 40 whose outer surface is formed in a polygon (for example, a hexagon, but is not limited thereto). can be combined with each other. As a result, there is no need to use a separate fastening member such as a screw to fix the boss portion 60 of the spiral blade 80 that is unevenly coupled to the rotating shaft 40.

On the other hand, in the conventional stirring device, a separate fastening member such as a screw is used to fix the connecting rod (7a) of the rod-shaped blade (7) to the rotating shaft (6). For this reason, when the rod-shaped blade (7) is repeatedly rotated in the forward or reverse direction inside the stirring container built into the main body (1), the screw that secures the connecting rod (7a) to the rotating shaft (6) loosens and must be checked frequently. It has the disadvantage of being

Referring to FIGS. 5(a,b) to 6, a stirring device for a food waste processor according to another embodiment of the present specification is

By driving the drive motor 20a, the first, second, third, and fourth spiral blades 100, 110, 100a, and 110a (as an example, four are shown to aid understanding, but are not limited to this) are rotated. In this case, food waste and microorganisms are repeatedly moved from the inner edge of the main body 1 toward the center by the rotation of the first and fourth spiral blades 100 and 110a mounted on both ends of the rotating shaft 40, and the rotating shaft 40 It is characterized in that food waste and microorganisms can be repeatedly moved from the center of the inside of the main body (1) to the edges and agitated by the rotation of the second and third spiral blades (110, 100a) mounted on the middle side.

At this time, the first, second, third, and fourth spiral blades (100, 110, 100a, and 110a) are alternately mounted on the rotation axis (40), and the first and fourth spiral blades are mounted on both left and right ends of the rotation axis (40). By rotating (100,110a), food waste and microorganisms are repeatedly moved from the edge of the inside of the main body (1) toward the center and agitated, and the second and third spiral blades (110,100a) mounted on the middle side of the rotating shaft (40) are agitated. The configuration except for repeatedly moving food waste and microorganisms from the center of the main body (1) to the edges by rotating them and agitating them,

Since the configuration is substantially the same as that of the agitator for a food waste processor according to an embodiment of the present specification, a detailed description of their configuration and functions will be omitted, and overlapping reference numerals indicate components having the same function.

Therefore, the agitating device for a food waste processor according to another embodiment of the present specification accommodates food waste and microorganisms in the agitating container (1a) of the main body (1) and then rotates the rotating shaft (40) by driving the driving motor (20a). When rotating, food waste and microorganisms can be uniformly stirred inside the stirring tank (1a) by rotating the first, second, third, and fourth spiral blades (100, 110, 100a, and 110a) alternately mounted on the rotating shaft (40). It becomes possible.

To explain this in detail, when food waste and microorganisms are stirred inside the stirring container 1a by rotation of the above-described first, second, third, and fourth spiral blades 100, 110, 100a, and 110a, the left and right sides of the rotation shaft 40 By rotating the first and fourth spiral blades 100 and 110a mounted at both ends, food waste and microorganisms can be repeatedly moved from the edge of the inside of the main body 1 toward the center and agitated.

At the same time, by rotating the second and third helical blades 110 and 100a mounted on the middle side of the rotating shaft 40, food waste and microorganisms can be repeatedly moved from the center of the inside of the main body 1 to the edge and agitated. .

In addition, when the first, second, third, and fourth spiral blades (100, 110, 100a, and 110a) rotate, food waste and microorganisms are repeatedly moved from the edge of the stirrer (1a) toward the center and stirred.
