The present invention relates to a food waste disposal device, and more particularly, to a stirring blade structure for uniformly stirring food introduced and installed in the food disposal device.

In general, the food waste disposal system is a device that uses fermentation bacteria to ferment food wastes and then leave only the fermentation residues generated and evaporate the rest, thereby eventually reducing the amount of garbage. It is true.

The food waste processor is configured with a hopper for feeding food into the upper part of the fermentation tank body, and a stirring blade for stirring the input food waste is rotatably mounted therein, and transmits the rotational force to one end of the stirring shaft on one side of the fermentation tank body. Power transmission means is to be installed.

In this state, when the food waste is put into the fermentor body and the power is applied, the food waste input by the stirring blade fixed on the stirring shaft is rotated while the stirring shaft receives the rotational force from the driving motor of the power transmission means. It is mixed evenly with and the fermentation process takes place.

For the fermentation, the food waste should be stirred evenly as a whole, but the conventional stirring blade simply does not form effective stirring because the stirring blade protrudes radially on the stirring shaft, and thus the food cannot be partially fermented. There was a problem that the chunks were extracted.

The present invention has been proposed to improve the above problems in the prior art, by providing a stirring blade structure that is continuous along the longitudinal direction of the rotating shaft to ensure that the agitation of food waste can be made uniformly in the entire stirring barrel There is a purpose.

The object is, the hopper for the input of food waste is configured in the upper portion, the stirring blade for evenly stirring the food waste put into the stirring container through the hopper is configured on the rotating shaft, the rotating shaft is at one end In the general food waste disposal device is configured to be connected to the drive motor, the stirring blade is composed of a curvature forming a predetermined curvature, and the support portion extending to form an integral structure on both sides of the curvature; Both ends of the stirring blade can be achieved through a stirring blade for a food waste processor, characterized in that the fastening means of the semi-circular form as a coupling means with the rotating shaft.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, looking at the overall configuration of the food waste disposal system according to the present embodiment through FIG. 1, the food input hopper 2 and the discharge part 5 for collecting food are disposed on the upper part of the stirring container 1 forming the inner space. ) Was provided, the hopper (2) is provided with a pair of grinding screws (4) driven by a separate drive unit (not shown) in order to crush the injected food, a driving motor in the stirring barrel (1) A rotating shaft 10 receiving the rotating force from the decelerator 8 through the speed reducer 8 was installed, and the stirring blade 20 of the present invention is coupled to the rotating shaft 10. Reference numeral 3 denotes a moving wheel, and 6 denotes a bearing bearing.

On the other hand, when looking at the structure of the stirring blade 20 of the present invention in more detail, as shown in the exploded view of FIG. Curvature portion 21 is formed to form a curvature, and on both sides there is a support portion 22 for stably supporting the curvature portion 21 with the flow force for the stirring material, the curvature portion 21 At one end of the extension portion 230 passing through the coupling portion 22 is formed to form an integrated structure with each other.

In particular, the support portions 22 and 22 'on both sides form an angle θ ₁ having a right angle to each other to support the curvature 21 more stably, and connect two stirring blades 20 to each other. When combined, as shown in FIGS. 1 and 5, the left and the right form symmetrical shapes and positions opposite to each other, thereby exhibiting an overall uniform stirring effect.

Then, the fastener 30, which is a fastening means for fastening the stirring blade 20 to the pivot shaft 10 in a detachable form, forms a divided semicircular shape and is configured to be coupled to both sides of the stirring blade 20, respectively.

In addition, the inner side of the fastener 30 is provided with a coupling key 32 protrudes as shown in FIG. 3, and a key groove 12 is formed on the outer circumferential surface of the rotation shaft 10 corresponding thereto, and the fastener 30 In the flange portion 31 formed extending to both sides of the coupling), the fastening hole 33 is penetrated by the fastening screw 35 and the nut 35 'so that the fasteners 30 can be coupled to each other. It was configured to make stable fixing of.

In the figure, reference numeral 30 'represents an auxiliary fastener for finishing fixing both ends of the stirring blade.

It looks at the effect of the mounting and use of the stirring blade of the present invention constituting such a configuration.

Stirring blade structure of the present invention to form a state in which the fastener 30 is integrally coupled to both ends of the stirring blade 20 is fixed to be made in the state in which the rotating shaft 10 is inserted into the stirring cylinder (1) do.

That is, as shown in FIG. 2, after the coupling key 32 of each fastener 30 is inserted into the key groove 12 of the rotating shaft 10 installed in the stirring barrel 1 to be opposed to pre-fastening, It is fixedly mounted using the fastening screw 35 and the nut 35 '.

At this time, both ends are finished by using a separate auxiliary fastener (30 ') made to achieve a state in which the stirring blade 20 is stably coupled along the entire length of the rotating shaft 10 as shown in FIG. .

In this state, when the food waste generated from the outside is introduced through the hopper 2, the food waste is crushed evenly by the grinding screw 4 and then accumulated on one side of the stirring tube 1, and then the operation of the driving motor 9 is performed. As the rotating shaft 10 received by the rotational force is rotated at a constant speed, the stirring blade 20 of the present invention rotates together to stir the food waste accumulated in the stirring barrel 1.

That is, as the stirring blade 20 is rotated, the food accumulated on one side in the stirring cylinder 1 flows by the action of the curvature 21 and the supporting members 22, 22 'and the whole stirring cylinder 1 In addition to being uniformly distributed on the inner space, it can be evenly stirred with a separately added fermenter.

In particular, the stirring blade 20 of the present invention forms a curvature shape in which the curvature portions 21 connect the support portions 22 and 22 'which form a right angle direction at 90 degrees in the diagonal direction, thereby increasing fluidity with respect to the agitated material. Will be. Therefore, when the two stirring blades 20 are successively mounted, as shown in FIG. 5, the four support parts 22 and 22 'form an angle of 90 degrees to equally divide 360 degrees, thereby providing a uniform stirring state. It can be maintained.

In addition, since the stirring blade 20 of the present invention forms a prefabricated detachable structure by the fastener 30, when the stirring blade 20 partially deforms or damages the blade, only the stirring blade 20 is used. It can be easily replaced has the advantage of easy repair and maintenance.

On the other hand, Figure 6 according to another embodiment of the present invention is configured in the form of a flat plate on both sides of the support portion 22, 22 'of the stirring blade 20 to form a certain thickness.

Particularly, at this time, as shown in FIG. 7 showing a cross-sectional view of the A'-A 'part of FIG. 6, the support parts 22 and 22' form a twisted shape that forms a predetermined inclination angle θ ₂ with respect to the rotation shaft 10. It is desirable to.

Due to such a torsional inclination angle θ ₂ , it is possible to perform agitation while moving the agitating material more effectively in the agitation vessel 1 at the site where the support parts 22 and 22 ′ are positioned during driving.

On the other hand, [Table 1] is an experimental example to compare the internal agitation and fluidity according to the change of the torsional inclination angle (θ ₂ ) of the support (22, 22 ') produced by various angles (○: excellent, △: normal, X: decrease)

Angle (°) Agitation liquidity 0 △ × 10 ○ △ 20 ○ △ 30 ○ ○ 40 ○ ○ 50 △ ○ 60 × ○

According to the above experimental example, when the inclination angle θ ₂ was less than 20 °, the inclination angle was too gentle as a whole, so that no satisfactory fluidity was achieved, and the angle θ ₂ was 50 ° or more. At that time, the torsion angle was too sharp from both ends to the middle, so the desired uniform agitation efficiency did not appear.

Therefore, as can be seen from the above results, the inclination angle (θ ₂ ) in the case of the plate-shaped support (22, 22 ') is 30 to 40 ° range can be achieved the best stirring and flow can be achieved with the fermentation aid It can be seen that the mixing takes place effectively in a short time.

In addition, since the portion is in the form of a flat plate it is possible to increase the flow efficiency for the stirring.

On the other hand, Figures 8 and 9 shows a stirring blade 20 structure according to another embodiment of the present invention.

In this case, the support parts 22 and 22 ', which are the weak part of fluidity against agitated material, are inclined at a predetermined angle (θ ₃ ) when viewed in a side structure, and a spiral curve rather than a straight form when viewed in a front structure. It is provided with a structure.

Due to such a structure, the agitated materials are provided with high fluidity not only by the curvature portion 21 but also by the support portions 22 and 22 'forming the inclined spiral structure during the rotation operation using the rotation shaft 10 as the driving shaft. It can be seen that more effective agitation can be achieved.

In addition, although specific embodiments of the present invention have been described and illustrated above, it is obvious that the stirring blade structure of the present invention may be variously modified and implemented by those skilled in the art.

For example, in the above embodiment, the cross-sectional shape of the stirring blade is described and illustrated as forming a round bar or a flat plate shape, but in addition, the cross-section shape of the stirring blade may be manufactured in various cross-sectional shapes, such as angle bars.

Therefore, such modified embodiments should not be understood individually from the technical spirit or the prospect of the present invention, and such modified embodiments should fall within the appended claims of the present invention.

As described above, the stirring blade of the present invention has a symmetrical structure in which support portions for improving rotational stirring efficiency are integrally formed at both ends of the curvature to increase fluidity of the stirring material. It can be improved.

In particular, the stirring blades can be easily installed in the state in which the rotating shaft is first mounted in the stirring barrel by making the assembly fastening structure easy to attach and detach the rotating shaft by the fasteners at both ends, partial repair of the stirring blade For repair or replacement has the advantage that can be made quickly.

In addition, in the case of forming both ends of the stirring blade in the form of a flat plate rather than a rod form to form a structure inclined with respect to the axial direction it is possible to maximize the stirring and fluidity of the stirring material.
