SCREW SUPPOTING APPARATUS FOR FOOD SWEEPINGS RECLAIMER}

The present invention relates to a dewatering press screw for removing water from food wastes. More specifically, in order to remove water from food wastes by screw rotation, the rebound load pressure acts on the bearing of the screw when the food wastes are pressed. The present invention relates to a screw support device of a household food waste treatment device for preventing friction noise from occurring and preventing the outlet from being deformed by the discharge pressure acting on the outlet from which the dehydrated food waste is discharged.

Food wastes and food wastes generated in daily life flow into the rivers through sewers and become decomposed, resulting in severe odors and destruction of ecosystems due to decontamination.

In order to solve this problem, foods discharged from each household are separately discharged and collected and recycled as feed. However, due to the high content of moisture contained in food waste, there is a hassle to dehydrate the food waste discharged, the situation is low effectiveness.

In order to solve this problem, a food waste treatment apparatus having a food waste dehydration and drying function has been developed. Such a food treatment device is usually installed at the bottom of the sink and has a function of filtering food waste flowing into the sewage pipe without collecting it into the stream and separately collecting it through a dehydration and drying process.

An example of a conventional food waste treatment apparatus having a food waste dehydration and drying function is disclosed in detail in Korean Utility Model Registration No. 309841.

As described above, the conventional food waste dehydration and drying apparatus 100 includes a food waste treatment device 100 that senses food waste introduced through an inlet by a sensor to screw food waste introduced while a driving motor operates. To the side. The conveyed food waste is conveyed upward by the screw rotation, and the food waste is compressed between the housing and the screw so that the contained water is dehydrated and discharged toward the outlet. The food waste discharged to the outlet is rotated on the outlet. After being cut finely by a cutter, it is transferred to a drying unit to perform a drying operation.

As described above, the food waste conveyed by the screw has a relatively narrow inlet at the outlet side of the upper side, so that the food waste is squeezed between the housing and the rotating screw, but the repulsive stress due to the reaction is applied to the shaft end of the screw. It will be concentrated. This load pressure is concentrated on the shaft end of the screw passing through the thrust bearing supporting the bearing part of the screw so that the shaft end of the screw deforms the plate supporting the lower part of the bearing to the lower side or the fixing cutter installed on the food waste outlet side to the upper side. Deformation causes the rotating cutter, which rotates with the screw, not to rotate, causing the screw and the screw housing to rotate together.

This is a dehydration effect as food waste is compressed by the rotating screw only when the housing installed around the screw is fixed. It is generated.

This problem not only impairs the processing device, but also causes most of the elements that make up the screw and the housing to be severely damaged, resulting in no operation.

As a result, although the bearing of the shaft end supporting the screw is installed, its effect is not effectively made, causing frequent failures, which is a problem of lowering the reliability of the quality.

In addition to these problems, there has been a problem in that the friction sound caused by the rotation between the screw shaft end and the plate is severely generated by the load pressure acting on the shaft end of the screw.

Therefore, the screw is transported to the upper side by the rotation of the screw and at the same time by dehydration through the action of the screw by the action of intensive load on the lower end of the screw, so that the severe deformation on both sides of the screw, that is, the discharge port and the bearing portion This is a problem that is difficult to expect the reliability of the operation.

The present invention was devised to overcome the malfunction of the screw disclosed in the Republic of Korea Utility Model Registration No. 309841 as described above, the object of the present invention is to transfer the food waste during screw rotation according to the sink attached food waste processing apparatus By compressing the food waste to dehydrate the water in the bearing, due to the reaction load caused by the reaction of the screw, the friction sound is not generated between the shaft end of the screw and the plate, and the deformation of the plate can be prevented. In order to achieve a smooth rotational motion to provide a screw support device for household food waste disposal apparatus having a stable coupling structure between the shaft end of the screw and the thrust bearing.

The screw support device of the household food waste disposal apparatus of the present invention is supported so that the screw is rotatable in the housing with a thrust bearing, and the diameter of the extended shaft inserted into the shaft cavity of the thrust bearing does not penetrate the shaft hole. And a portion of the circumferential surface is cut radially inward so that the circumferential surface is symmetrical with each other, and a stepped portion formed with a diameter larger than the diameter of the thrust bearing is further provided, and is inserted around the circumferential surface of the stepped portion. This can be solved by installing more packings to prevent friction between the thrust bearings and to prevent oil leakage.

In the present invention, the diameter of the lower shaft end of the screw is the same as the diameter of the shaft hole of the bearing. However, the circumferential surface is cut into a half-moon shape and the stepped portion having the diameter larger than the diameter of the shaft hole of the bearing is formed to form the stepped portion of the screw. By preventing the additional bearing from protruding out of the shaft hole, even if the load pressure generated during the rotation of the screw is concentrated toward the bearing, the bearing can rotate, but friction noise with the plate does not occur, and the load pressure is distributed to the thrust bearing, resulting in the rotation of the screw. It will be able to easily support.

With reference to the accompanying drawings for the screw support device of the household food waste treatment apparatus according to the present invention will be described in detail as follows.

<Example>

Figure 2 illustrates a conventional household food waste processor, Figure 2 is an exploded perspective view showing the components of the screw installed in the waste processor illustrated in Figure 1, Figure 3 is a cross-sectional view, Figure 4 is a A enlarged cross-sectional view of A.

As can be seen in the drawing, the shaft end 11 of the screw 10 according to the present invention has a stepped portion 12 formed by a difference in diameter, and an extension shaft 13 having a diameter smaller than the stepped portion 12. Is formed.

The diameter of the extension shaft 13 is made of the same diameter as the inner diameter of the shaft hole 21 of the thrust bearing 20, the circumferential surface of the extension shaft 13 is the surface that is inserted into the shaft hole 21 symmetrical with each other The circumferential surface of is cut flat and cut out. The length of the extension shaft 13 is at least shorter than the length of the shaft hole 21 does not protrude out of the shaft hole 21 of the thrust bearing 20.

This is because the stepped portion 12 of the screw 10 is caught on the inlet side of the shaft hole 21 of the thrust bearing 20 so that the extension shaft 13 does not penetrate the shaft hole 21, so the pressure due to the load pressure is thrust. Even if it extends to a bearing, the rotational motion of the thrust bearing 20 becomes possible.

As described above, the screw support device of the household food waste treatment apparatus according to the present invention can effectively support the rotational movement of the screw so that malfunctions do not occur in the automatic dehydration and drying of the food waste, as well as friction noise during rotation. It is possible to prevent deformation of the plate or plate.
