Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a kitchen waste processing machine that dehydrates and recovers kitchen waste.

・ (Conventional technology) FIG. 4 shows a conventional centrifugal separation type kitchen waste processing machine.

This kitchen waste processing machine is equipped with an inverted truncated cone-shaped dewatering basket (11) which rotates at high speed in a casing 10, and a crushing section 14 consisting of a fixed blade 12, a rotary hammer 13, and the like.

The kitchen waste dropped into the hopper 16 together with water from the sink 15 is crushed by the crushing section 14 and blown to the inner bottom periphery of the dewatering basket rack 1-11 by the centrifugal force. The water is subjected to centrifugal force by the basket 11 and rises along the tapered inner circumferential wall of the dewatering basket 1-11, is dehydrated while reaching the discharge chamber 17, is blown away by the blades 18, and is discharged into the storage bag 19. The separated water passes through the dehydration chamber 20 and is discharged from the drain pipe 21.

(Problems to be Solved by the Invention) However, the conventional kitchen waste processing machine described above has the following problems.

In other words, some kitchen waste containing water is extremely sticky. Therefore, after using the dehydration basket for a certain period of time,
Sticky matter adheres to the dehydration hole of 1, causing clogging.

Conventionally, there was a problem in that when the dehydration basket 11 became clogged, water flowing down from the sink 15 overflowed from the dehydration basket 11 and directly flowed into the storage bag 19 from the discharge chamber 17.

Therefore, the present invention has been made to solve the above problems, and its purpose is to prevent water from the sink from immediately flowing into the storage bag even if the dehydration basket becomes clogged. To provide a kitchen waste disposal machine capable of finding and cleaning clogging.

(Means for solving the problems) The kitchen waste processing machine of the present invention according to the above object includes a casing,
A dewatering basket is disposed inside the casing and rotates at high speed around an axis in a horizontal plane, and the dewatering basket is protruded from the inner wall of the casing toward the circumferential wall of the dewatering basket, and the inside of the casing together with the dewatering basket is divided into a dewatering chamber and a garbage discharge chamber. This kitchen waste processing device is equipped with an inward protruding section for partitioning, and a ho-7 bar for throwing kitchen waste onto a dewatering basket, and by rotating the dewatering basket at high speed, the thrown kitchen waste is centrifugally dehydrated and sent to a discharge chamber for discharge. In the machine, a gap is provided between the inner end surface of the inward protrusion and the outer circumferential surface of the dewatering basket to serve as a flow path for water that overflows the dehydrating basket when the dehydrating basket becomes clogged, and the upper outer peripheral surface of the dehydrating basket is is provided with a flange portion outwardly at a predetermined distance from the lower surface of the inwardly protruding portion, and on the upper surface of the flange portion,
The dewatering bath is characterized by having a spiral partition plate that extends in the direction of rotation of the dehydrating basket centered on the axis of the dehydrating basket and is vertically disposed toward the lower surface of the inwardly projecting part.

(Function) By rotating the dewatering basket at high speed, the kitchen waste placed in the dehydrating basket is centrifugally dehydrated and rises to the discharge chamber and is discharged.

If the machine is operated for a long period of time, the dehydration hole in the dehydration basket will inevitably become clogged.

When the dehydration hole is clogged, water overflows the dehydration basket, flows into the dehydration chamber through the gap provided between the inward protrusion and the hydrophilic basket sort, and is collected, and does not flow into the storage bag.

Note that when operating in this state, some water will flow into the storage bag, but the problem of all of the water flowing in and overflowing from the storage bag will be resolved. At this point, it can be determined that the hydrophilicity has decreased, so the dehydration basket can be cleaned.

During normal operation, the gap is hidden from the dehydration chamber side by the flange and partition plate provided on the dehydration basket.
Water does not enter the discharge chamber from the dehydration chamber through the gap.

(Embodiments) Hereinafter, preferred embodiments of the present invention will be described in detail based on the accompanying drawings.

In FIG. 1, 30 is a cylindrical casing, which is sealed by a bottom plate 31 and a top plate 32.

Note that 39 is a bearing, and 40 is a cap fixed to the output shaft 37, which covers the boss 38 to prevent moisture from entering into the boss.

At the upper end of the output shaft 37, there is a disc 4 equipped with a hammer 41 on the upper surface.
2 is fixed, and as the disc 42 rotates together with the output shaft 37, the kitchen waste put into the hopper 33 is crushed by the hammer 41 and the fixed blade 43 provided on the inner wall of the hopper 33, and the crushed kitchen waste is crushed by the hammer. 41 and the fixed blade 43 through the cylindrical shaft body 35 and fall into a dewatering basket to be described later.

44 is a dewatering basket disposed inside the casing 30, which has a shallow dish shape and is connected to the output shaft 3 passing through the center of the bottom surface.
7, and rotates at high speed in a horizontal plane around an output shaft 37.

The outer periphery of the uppermost end of the dehydration basket 44 is surrounded by an inward protrusion 45 that protrudes from the inner wall of the casing 30, and the dehydration basket 44, the inward protrusion 45, and the casing 30 form a dehydration chamber 46.
form.

A gap B is formed between the inward protrusion 45 and the outer peripheral wall of the dehydration basket 44, which serves as a flow path for water that overflows the dehydration basket 44 when the dehydration basket 44 becomes clogged.

Further, a flange portion 47 is provided on the upper outer periphery of the dewatering basket 44 so as to be spaced from the inwardly protruding portion 45 by some distance in the vertical direction.

An annular partition plate 48 is suspended toward the upper surface of the flange portion 47 at a position on the lower surface of the inwardly protruding portion 45 at a position slightly spaced from the inner wall surface of the casing 30 .

Further, a partition plate 49 is vertically provided on the upper surface of the flange portion 47 and located further inside than the annular partition plate 48 . This partition plate 49 is connected to the dehydration basket 44 as shown in FIG.
The dewatering basket 44 is provided in a spiral shape that extends in the rotational direction of the dewatering basket 44 around the axis of the dewatering basket 44 .

A large number of dewatering holes 50 are opened in the peripheral wall and bottom surface below the flange portion 47 of the dewatering basket 44, and the hopper 3
3 into the dewatering basket 44 and water centrifuged from the kitchen waste by rotation of the dehydrating basket 44 are separated into the dehydrating chamber 46 from the dehydrating hole 50 and drained from the drain port 51 provided in the casing 30. .

Next, 55 is a screw, and screw blades 57 are provided on the outer periphery of a cylindrical body part 56 that opens in the vertical direction.
It is fitted onto the outside so that it can rotate freely around its axis. The outer periphery of the screw blade 57 is in sliding contact with the inner peripheral wall of the dewatering basket 44, and the lower starting end of the spiral of the screw blade 57 is in sliding contact with the inner bottom surface of the dehydrating basket 44 and a part of the corner of the inner peripheral wall, and the lower surface of the cylindrical body part 56 is in sliding contact with the inner peripheral wall of the dewatering basket 44. By slanting from the bottom sliding contact part to follow the spiral slope (lead angle),
An opening 58 is formed between the lower surface of the cylindrical body portion 56 and the inner bottom surface of the dewatering basket 44 . Therefore, the kitchen waste that falls from the cylindrical shaft 35 onto the inner bottom surface of the dewatering basket 44 is blown toward the inner circumferential wall of the dewatering basket by the centrifugal force from the dewatering basket 44.

The screw 55 is rotated at high speed by a drive motor 36 that rotates the dewatering basket 44 .

That is, the belt 63 is hooked between the pulley 61 provided at the lower end of the rotating shaft 60 provided on the machine base 59 outside the casing 30 and the boot 17-62 provided on the output shaft 37 of the drive motor 36. Boo IJ-64 provided at the upper end of the rotating shaft 60 and a pulley 65 provided at the portion of the upper end of the screw 55 that protrudes outside the casing 30.
A belt 66 is passed between the two to form a drive transmission system.
The driving force of the drive motor 36 is transmitted to the screw 55 through the drive transmission system, and the screw 55 is rotated at high speed in the same direction as the dewatering basket 44.

In this embodiment, the screw 55 is rotated slightly faster than the dewatering basket 44.

Therefore, the screw 55 is rotated slowly relative to the dewatering basket 44, so that the kitchen waste in the dewatering basket 44 is gradually transported upward along the inner circumferential wall of the dewatering basket 44 by centrifugal force.

Note that 52 is a bearing, and 67 is a fixing ring that prevents the screw 55 from being removed from the cylindrical shaft body 35.

At the upper part of the casing 30, there is a top plate 32 and an inward protrusion 45.
, dehydration basket 44, etc. (Thus, a discharge chamber 68 is formed that is separated from the dehydration chamber 46, and a discharge port 69 is opened at one end of the discharge chamber 68.

A vane body 70 extends into the discharge chamber 68 from the upper end surface of the screw 55, and rotates at high speed within the discharge chamber 68 as the screw 55 rotates.

71 is a storage bag that is detachably attached to the discharge port 69.

The kitchen waste processing machine configured in this way has a hopper 33.
At the upper end, attach the mounting tube 7 to the kitchen waste input lower 3 of the sink 72.
It can be attached via 4 etc.

Further, a drain pipe 75 is connected to the drain port 51.

``Explain the operation by saying it.

The kitchen waste that has flowed down from the sink 72 into the hopper 33 along with water is transferred to the hammer 4 which is rotated at high speed by the drive motor 36.
1 and the fixed blade 43, and flows down from the gap between the hammer 41 and the fixed blade 43, through the cylindrical shaft body 35, and onto the inner bottom surface of the dewatering basket 44. Most of the water from the sink 72 flows through the dehydration hole 50 provided at the bottom of the dehydration basket 44.
The water flows down into the dehydration chamber 46 and is drained from the drain pipe 75.

- When the dewatering basket 44 is rotated at high speed, the centrifugal force causes the screw and the dehydrating basket 4 to
4 to a part of the corner of the dewatering basket 44 through the opening 58 between the inner bottom surface of the dewatering basket 44 and the inner bottom surface of the dewatering basket 44. Here, the kitchen waste is fed by a screw 5 which is rotated at a high speed slightly higher than that of the dewatering basket 44.
5, and transported upward while undergoing centrifugal dehydration. The dehydrated kitchen waste is thrown out from the upper surface of the screw 55 into the discharge chamber 68 by centrifugal force, and is knocked out from the discharge port 69 into the storage bag 71 by the impeller 70 rotating at high speed together with the screw 55.

As described above, since the outer end of the screw blade 57 of the screw 55 is in sliding contact with the inner circumferential wall of the dehydration basket 44, the inner sliding surface of the dehydration basket 44 is constantly rubbed, and clogging is prevented as much as possible. In addition, the time during which kitchen waste remains in the dewatering basket 44 and undergoes centrifugal dehydration is determined by the rotation ratio of the dewatering basket 44 and the screw 55, regardless of the type of kitchen waste, so the rotational speed is the same based on the kitchen waste that is difficult to dewater. The optimal dehydration effect can be achieved by setting the ratio.

Note that when used for a long period of time, highly sticky kitchen waste gradually adheres to the dewatering hole 50 of the dehydrating basket 44, causing the dehydrating hole 50 to become clogged.

When the dewatering hole 50 is clogged in this way, the water that has flowed from the sink 72 into the dehydrating basket 44 along with the kitchen waste is not discharged and overflows the dehydrating basket 1-44.

In the kitchen waste disposal machine of the present invention, this overflow water flows into the dehydration chamber 46 from the gap B and is collected, and the storage bag 7
This eliminates the situation of inflow into the room.

Note that when the kitchen waste disposal machine is operated in this state, overflow water is blown away by the blade 70 and a portion of the overflow water is discharged into the storage bag 71, but almost all of the overflow water is discharged into the storage bag 71 as in the conventional case. There is no problem of the liquid flowing into the 71 and overflowing to the outside.

If some of the overflow water flows into the storage bag 71 as described above, when replacing the storage bag 71, it can be confirmed that the dehydration rate of the kitchen waste has decreased, and if this situation occurs, disassemble the kitchen waste processing machine. to clean the dehydration basket 44,
Clogging can be cleared.

Note that during normal operation, since the dehydration chamber 46 and the discharge chamber 68 communicate with the gap B, there is a possibility that water may enter the discharge chamber 68 from the dehydration chamber 46 .

That is, the centrifuged water becomes a mist in the dehydration chamber 46, and this mist enters the discharge chamber 68 through the gap B and may adhere to kitchen waste. In addition, the dehydration basket 44
Since the dehydration basket is rotated at high speed, the water discharged from the dehydration basket is blown diagonally toward the inner wall of the dehydration chamber 46, so that the water rotates and rises along the inner wall of the dehydration chamber 46.
It enters the discharge chamber 68 through the gap B, and the blade body 7
0 may be discharged into the storage bag 71.

However, in the present invention, as described above, the flange portion 47 extends from the top of the dewatering basket 44, and the spiral partition plate 49 is provided on the flange portion 47, so that the gap B is closed by the flange portion 47 and the partition plate 49. Since it is hidden, mist and droplets will not enter into the discharge chamber 68 from the gap B.

Further, the annular partition plate 48 provided on the lower surface of the inwardly protruding portion 45 blocks water that attempts to rotate and rise along the inner wall of the dehydration chamber 46, thereby preventing it from flowing into the discharge chamber 68.

Therefore, even though the gap B, which is an inlet for overflow water, is provided as described above, water does not enter the discharge chamber 68 from the dehydration chamber 46, and the kitchen waste is discharged into the storage bag 71 with a predetermined dehydration rate. It is.

Note that the water rising along the inner wall of the dehydration chamber 46 is removed by the partition plate 49.
The annular partition plate 48 does not necessarily need to be provided, since the annular partition plate 48 can also be shut off.

FIG. 3 shows another embodiment, in which the same members as in the above embodiment are given the same reference numerals and their explanations will be omitted.

In this embodiment, the screw 55 is driven by the drive motor 36.
and the dewatering basket 44 is driven via a drive transmission system. That is, the screw 55 is connected to the post 76 fitted to the output shaft 37.
is directly fixed on the output shaft 37 by being fixed via a radial support rod 77 to
-44 is provided on the output shaft 37 so as to be freely rotatable with respect to the output shaft 37, and is connected to the output shaft 37 through a gear device 78.
rotation is transmitted.

In this embodiment as well, a flange portion 47 is provided on the top of the dewatering basket 44, and a spiral partition plate 49 is provided on this flange portion 47. Further, an annular partition plate 48 is provided on the lower surface of the inwardly protruding portion 45 .

It is clear that this embodiment also provides the same effects as described above.

In each of the above embodiments, the screw 55 is rotated at a high speed slightly faster than the dewatering basket 44 so that the kitchen waste is transported by the screw. As you can see, the kitchen waste is rotated in a direction that is not used for feeding, and the dewatering basket 44 is rotated in the same direction and at a slightly higher speed (higher speed) than the screw, and this speed difference causes the kitchen waste to be placed on the screw blade 57. It may also be conveyed upward by feeding.

By rotating the screw 55 in the opposite direction to that in the embodiment described above, it is possible to prevent kitchen waste from becoming entangled with the screw.

In each of the above embodiments, an example using a screw has been given, but it goes without saying that the present invention can also be applied to a garbage processing machine that does not use a screw, as shown in FIG.

The present invention has been variously explained above with reference to preferred embodiments, but the present invention is not limited to these embodiments, and it goes without saying that many modifications can be made without departing from the spirit of the invention. That's true.

(Effects of the Invention) As described above, according to the kitchen waste disposal machine according to the present invention, since a gap is provided between the inner end surface of the inwardly protruding part and the circumferential surface of the dewatering basket sauce, when the dewatering basket becomes clogged, The water overflowing from the dehydration basket flows into the dehydration chamber through the gap and is collected, eliminating the conventional problem of flowing into the storage bag from the discharge chamber and overflowing.

In addition, even during normal operation, the void is hidden by the flange provided on the top of the dehydration basket and the partition plate provided on the flange, so mist and droplets from the dehydration chamber do not enter the discharge chamber through the void, preventing kitchen waste from entering the discharge chamber. is discharged while maintaining a predetermined dehydration rate.

Further, by providing an annular partition plate on the lower surface of the inwardly projecting portion, it is possible to block water rising along the wall of the dehydration chamber, effectively preventing moisture from flowing into the discharge chamber.
