Apparatus for removing unsuitable materials for pulverization from the water-containing waste before pulverizing the water-containing waste, especially by rotating the water-containing waste in the pipe by injecting high-pressure air into the pipe. A new crushing unsuitable substance in the hydrated waste configured to remove the crushing unsuitable substance from the hydrated waste by the difference in specific gravity between the crushing unsuitable substance in the hydrated waste and the crushing eligible product generated during this rotation. Regarding the removal device.

(Problems to be solved by conventional techniques and devices) Conventionally, a large amount of water is contained in vegetable residues, food residues, etc. discharged from kitchens such as general households, restaurants, and hospitals. In this state, since it is difficult to incinerate as it is, dehydration is performed on the garbage containing water, which is the water-containing waste.

When the water-containing waste is dehydrated, the water-containing waste is sent under pressure to a crusher having a built-in cutter that rotates at high speed, and the water-containing waste is crushed, mixed, and stirred. Has developed a device for finely crushing water-containing waste, which has been designed to reduce the water content in raw garbage by allowing water to naturally fall from the water-containing waste.

However, if the water-containing waste contains unsuitable materials for crushing such as spoons and forks, these unfit materials will be sent to the crusher together with raw garbage.
In this case, there is a problem that the teeth of the cutter incorporated in the crusher may be damaged.

In particular, the cutter built in the crusher is a tooth with a hardness suitable for crushing vegetable residues, food residues, etc. There is a problem in that a spoon, a hawk, etc. cannot be crushed, and conversely, the cutter teeth of the crusher may be damaged.

Further, as shown in FIG. 3, conventionally, a metal which is a non-combustible substance contained in raw garbage is detected in order to prevent an unsuitable substance made of a metal having high hardness from being fed into a crusher. The passage sensor 15 is provided in the pipe 13, and when a metal or the like is detected by the metal passage sensor 15, the two electric valves 17a17b formed in the vicinity of the metal passage sensor 15 are closed and the two electric valves 17a17b are used. A device has been developed which is configured to discharge the raw garbage containing the unsuitable material for crushing existing in the closed plastic pipe 13 portion from the metal discharging electric valve 19 to the outside.

However, even in the case of using the metal excluding device, there is a crushing unsuitable substance which is not detected by the metal passage sensor 15 or a crushing unsuitable substance which cannot be completely removed from the inside of the pipe 13 even if it is detected. When an unsuitable material for crushing is sent to the crusher, there is a problem that the teeth of the cutter built in the crusher may be damaged.

In particular, since the cutter tooth built in the crusher has a complicated structure, when the cutter tooth in the crusher is damaged as described above, replacement of the cutter tooth becomes complicated, and maintenance is difficult. There is a problem that it requires a lot of labor and cost.

The present invention was developed in order to solve the above-mentioned conventional problems, and it is possible to efficiently remove unsuitable materials for pulverization from the water-containing waste before pulverizing the water-containing waste containing garbage. The present invention provides a new crushing unsuitable substance removing device configured to remove the crushing unsuitable substance.

(Means for Solving the Problems) In order to achieve the above object, the present invention is directed to a pipe connected to a crushing unit for crushing water-containing waste by injecting high-pressure air into the pipe.

And a device for removing unsuitable materials for crushing.

(Operation) As described above, in the present invention, the high-pressure air is injected into the pipe connected to the crushing unit for crushing the water-containing waste, so that the water-containing waste rotates in the pipe. Will be done.

As described above, by rotating the water-containing waste, the water-containing waste containing the material unsuitable for grinding is subjected to centrifugal separation, and the difference in specific gravity between the material not suitable for grinding and the material eligible for grinding is generated during the rotation. As a result, unsuitable materials for grinding are removed from the water-containing waste.

Embodiment An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a front view of an apparatus for removing unsuitable material for crushing according to the present invention, FIG. 2 is a sectional view of the same main part, and FIG. 3 is an apparatus for removing unsuitable material for crushing according to the present invention. The piping system diagram is shown.

In this embodiment, a crushing unit for crushing water-containing waste is used.
The pipe 13 connected to 23 is provided with a high-pressure air injection unit 100 configured to rotate the water-containing waste in the pipe by injecting high-pressure air into the pipe, and further, the rotating water-containing waste. An apparatus 21 for removing unsuitable material for grinding in water-containing waste, which is provided with a removing unit 102 configured to remove unsuitable material for grinding.

As shown in FIG. 3, the water-containing waste is collected in a garbage storage chamber 11 formed on the floor of the kitchen room 7 and provided with a washing shower 9, and then sent into the pipe 13. Be done.

Further, when the raw garbage contains a metal or the like that is not suitable for crushing, a metal passage sensor provided in the pipe 13
It is detected by 15, and is opened to the outside from the metal discharging electric valve 19 by opening and closing the electric valves 17a 17b formed near the metal passage sensor 15.

Next, through the metal catch portion 21 according to the present invention, the water-containing waste is sent to a crusher 23 having a built-in cutter that rotates at high speed, and the crusher 23 crushes, mixes, and agitates the water-containing waste. The water-containing waste is finely crushed by applying.

Next, the water-containing waste finely crushed as described above is stored in the storage tank 27 in which the rotary valve 25 for fixed amount feeding is installed, and then the water-containing waste crushed is stored in the storage tank 27. The waste is sent to the dehydrating device 3 for the water-containing waste that is configured to perform centrifugal separation by rotating the part 1 and to suck the separated water, and the waste with the water further removed is discharged through the outlet 31. Then, it is put in a bag 65 for collection and incinerated.

The high-pressure air injecting unit 100 is attached to a pre-process of the pulverizing unit 23 for pulverizing water-containing waste, and is further attached at an angle forming a tangent to the outer peripheral surface of the pipe 13.
