JP2000070912A - Crude refuse treating device - Google Patents

Abstract

PROBLEM TO BE SOLVED: To obtain a crude refuse treating device adequate for executing the treatment of crude refuse into which water is incorporated. SOLUTION: This crude refuse treating device comprises a blade shredding shaft of a shredding section for shredding the crude refuse, a dehydrating screw 9 for dehydrating the shredded crude refuse and a decomposing and annihilating section 13 for decomposing the crude refuse by microorganism-component to gases and water and remarkably annihilating the crude refuse. The crude refuse fed from a feeding port is blade shredded by the blade shredding shaft and is passed through the sealing water formed of a partition plate and drain port. While the crude refuse is rotated together with the water by the dehydrating screw 9, the crude refuse is lifted upward. At this time, the crude refuse is passed through a filter 10 on the sidewall of the dehydrating screw 9, by which the water and the crude refuse are separated. The crude refuse separated from the water is transferred to the decomposing and annihilating section where the crude refuse is decomposed and annihilated by the microorganism-component.

Description

DETAILED DESCRIPTION OF THE INVENTION

The present invention relates to a garbage disposal apparatus suitable for treating garbage mixed with water.

[0002]

2. Description of the Related Art Water-containing garbage, for example, garbage generated at home, has conventionally been temporarily collected in a sink of a sink and then transferred to another place for disposal. Alternatively, it was shredded with a disposer, and was directly poured into sewage. However, in recent years, garbage has been shredded with a disposer, dewatered or premixed with water and garbage in advance, and only garbage has been introduced into the garbage disposal and destruction section. It has been proposed to reduce it.

[0003]

However, the above-mentioned garbage disposal apparatus generates sound to crush the garbage with a disposer, and also needs to separate water and garbage, and also, There is no water seal for preventing the odor from flowing backward between the garbage and the elimination part for eliminating the garbage, and there is a problem that the odor flows backward.

[0004] The present invention has been made in view of the above problems, and in each processing step, the generation of noise is reduced. In particular, in a multi-family house, a major problem and the backflow of odor are prevented by sealing water, and the cost is reduced. An object of the present invention is to provide a garbage disposal device.

[0005]

According to the present invention, there is provided an apparatus for treating garbage in which a shredding section, a dewatering section, and a elimination section are sequentially arranged to achieve the above object. Then, the food waste is pressed against the blade chopping shaft by the force of gravity and the flow of water by the wedge-shaped food waste input passage which becomes narrower as it goes further. In addition, the outer circumference of the blade shredder shaft is partially screw-shaped to generate a force that pushes garbage to the narrow part of the passage, which also has the effect of improving the sticking of the blade shredder shaft to the blade. Let it drip. Also, the two parallel shredder axes rotate so as to pinch in opposite directions, but at that time, due to the difference in the peripheral speed of the outer periphery, the pinched garbage becomes in a form of being cut by pulling with a blade in addition to the pushing force. In addition, the blade is cut obliquely with respect to the direction in which the garbage is inserted while facilitating the shredding of the garbage, thereby having a function of cutting the garbage and an effect of preventing garbage from being accumulated between the blades.

[0006]

According to the first aspect of the present invention, in cutting the garbage blade, the blade attached to the rotating shaft, particularly when cutting a particularly large blade, has poor sticking to the blade, but the details of this blade generate noise. It is intended to minimize and eliminate the disadvantages.

According to the second aspect of the present invention, the screw provided in the dewatering unit rotates the refuse, applies centrifugal force from a hole in the cylindrical portion of the outer wall of the screw while rolling up the water, and discharges water. And clogging of dust blocking the holes is prevented by contact with the outside of the screw.
In addition, it is possible to prevent the backflow of odor by sealing up water by rolling up garbage under water.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment shown in the drawings of a garbage processing apparatus of the present invention will be described. FIG. 1 is a side view of the garbage processing apparatus of the present invention. In the figure, 1 is a garbage input port, 2 is an input passage narrower as it goes ahead, 3 is a partition plate forming the water seal 8, 4 and 5 are two parallel blade cutting shafts described later,
Reference numeral 6 denotes an electric motor that drives the blade shredding shaft. The blade shredding shafts 4 and 5 are interlocked by a gear, and the blade shredding shafts 4 and 5 generate a rotation difference due to a difference in the size of the gear. The tooth-sharpening shafts 4 and 5 have teeth having a shape of 7 attached to the outer periphery at regular intervals. The blade shredding shafts 4 and 5 rotate so as to involve the garbage.
The entrained garbage is shredded by two forces, a force for tearing and a force between the blade and the peripheral speed of the blade.
On the other hand, the garbage that has not been caught is also pushed in the narrow direction of the charging passage by the force of the flow of water and the blade 7 formed obliquely to the circumference of the shaft, and is eventually caught in the blade shredding shaft, and the aforementioned Shredded as follows. Therefore, the garbage is shredded without remaining in the charging passage. The cut garbage is wound up by the screw 9 while rotating together with the water. At that time, pass through the non-rotating filter 10 on the outer wall of the screw,
The water falls down, is separated from the garbage, and flows through the drain passage 11 to the sewage. The garbage separated from the water passes through the minute elimination chamber input port 12 above the screw 9 and enters the minute elimination chamber 13. The garbage entering the elimination chamber is temperature-controlled by the heater 14 to a temperature suitable for elimination of the garbage, and at the same time, stirred by the stirrer 15 to activate the tiny garbage and quickly remove the garbage. Eliminate the minute.
The gas generated by the decomposition is sent to the sewage by the fan 16 together with the moisture. Therefore, garbage can be easily treated together with water without generating odor.
