[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a disposer that is installed in a sink or the like and crushes and discharges soot.
[0002]
[Prior art]
The disposer is used for crushing cocoons and the like for home and business use, and is basically different from a crushing device such as a garbage disposal site. However, both have similarities in that they break the cocoon and can be crushed. As such a crushing device, a device disclosed in Japanese Utility Model Laid-Open No. 57-17741 has been known. This is provided with a hopper at the top of the upright cylindrical main body, a primary pulverization chamber directly below the hopper, a secondary pulverization chamber directly below the primary pulverization chamber, and a discharge chamber and a blower chamber at the lower part. The rotary shaft is concentrically supported through the primary pulverization chamber to the blower chamber. The rotary shaft has an inner cylinder A passing through the primary pulverization chamber, a secondary pulverization chamber and a discharge chamber, and an inner cylinder B passing through the blower chamber. The rotating shaft and the inner cylinders A and B are rotated by a motor via a groove pulley and a V belt. Steel concentrators are loosely fitted to the inner cylinders A and B, and in particular, the inner cylinder B is attached in multiple stages in the axial direction. Vertical ribs project from the inner wall surfaces of the primary pulverization chamber and the secondary pulverization chamber.
[0003]
In the conventional crushing apparatus configured as described above, the processed material such as raw garbage introduced into the primary crushing chamber is composed of a steel bundling body and a vertical rib that are rotated horizontally by rotation of a rotating shaft driven by a motor. It is crushed by interaction. The crushed material enters the secondary pulverization chamber and is further finely crushed by the interaction of the steel bundling body and the longitudinal rib. The crushed material is discharged from the outlet through the rotation of the steel wire converging body and the wind from the blower chamber, and is transferred to an external sorting device.

[0014]
Reference numeral 12 denotes the bottom of the sink. When the upper end of the hopper 4 and the bottom 12 of the sink are connected, the disposer is mounted on the sink. A discharge port 13 is attached to the lowermost part of the pulverized material discharge path. Reference numeral 14 denotes a water tap. In FIGS. 1 and 2, 15 is a plate constituting the roller chain 7, and 16 is a pin. The base end portion of the crushing blade 8 is sandwiched between the plates 15 of the roller chain 7 and joined by pins 16, and the planar shape thereof is substantially fan-shaped. Further, as shown in FIG. 1, the crushing blade 8 a has a crank shape with a step below so that the lowest point of the crushing blade 8 a is located below the lowest point of the roller chain 7.

Reference numeral 17 denotes a plurality of claws provided on the periphery of the bottom plate 9. The rotary crushing body is not limited to a roller chain, and may be a chain member such as a chain, a flexible body such as a wire or nylon (registered trademark), a rope, or an elastic body such as rubber or a spring. It should be hard to lock during crushing.
[0016]
The operation of the disposer configured as described above will be described below. First, the soot is introduced from the disposer inlet 10. Next, the water faucet 14 is opened and the motor 1 is started while flowing water, so that the roller chain 7 and the crushing blade 8a are rotated. Then, the roller chain 7 and the crushing blade 8a are opposed to the inner wall of the hopper 4, that is, the inner surface of the crushing part, by centrifugal force. The thrown straw is rotated by the roller chain 7 and is blown toward the crushing blade 8a and the fixed blade 6 by centrifugal force. Here, the scissors are cut and crushed between the fixed blade 6 and the crushing blade 8a rotating at high speed.
[0017]
Further, it is finely pulverized between the crushing blade 8 a and the claw 17 of the bottom plate 9 that are close to each other. The gap between the claws 17 on the periphery of the bottom plate 9 is optimally about 1 to 6 mm, and the pulverization particle size can be adjusted by the distance of the gap. The distance between the tip of the claw 17 and the peripheral side surface of the crushing chamber is optimally about 0.1 mm to 4 mm, and the crushing particle size can be adjusted even at this distance. The same result can be obtained even when the claw 17 protrudes inwardly from the peripheral side surface of the grinding chamber instead of from the bottom plate 9. As shown in FIG. 2, when the crushing blade 8a has a substantially fan shape, the centrifugal force acting on the crushing blade is increased, and crushing and fine crushing of difficult-to-crush products can be performed efficiently. Thereafter, the crushed soot and water flow into the pulverized material discharge passage 13 through a gap between the bottom plate 9 and the inner wall of the pulverization part, and are discharged from the drain port 13 to the outside.

Then, the roller chain 7 and the crushing blade 8b are in a state of facing the inner side of the hopper 4, that is, the inner surface of the pulverized portion, by centrifugal force. The thrown straw is rotated by the roller chain 7 and is blown toward the crushing blade 8b and the fixed blade 6 by centrifugal force. Here, the scissors are cut and crushed between the fixed blade 6 and the crushing blade 8b rotating at high speed. Further, it is finely pulverized between the crushing blade 8b adjacent to the claw 17 of the bottom plate 9. Further, by forming the raised portions 9a on the bottom plate 9, a fine crushing effect can be obtained.
