BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a residue treatment apparatus, and more particularly to a residue treatment apparatus suitable for treating organic waste such as raw garbage having a large water content.

[0002]

2. Description of the Related Art Conventionally, when treating organic waste such as raw garbage, that is, a residue, the residue such as raw garbage to be treated is first crushed into fine pieces, and then the fine pieces are crushed. A method has been used in which a heating agent such as calcium oxide (CaO) is added to the residue and water content in the residue is removed by its exothermic effect to reduce the total amount of the residue.

A separate crushing device and a stirring tank have been used for the work of subdividing the residue and the work of stirring the residue and mixing the heating agent.

FIG. 9 shows a conventional crushing device 100. The crushing apparatus 100 shown here includes a cylindrical crushing container 101 that is opened in the vertical direction, and a receiving member 102 that is connected to the lower portion of the crushing container 101 and that receives the crushed residue and guides it toward the discharge pipe 103 side. , A crushing mechanism 110 disposed in the lower inside of the crushing container, and the crushing mechanism 11

The crushing mechanism 110 is provided in the lower part of the crushing container 101, and a plurality of groove-shaped fixed blades 111 formed uniformly along the vertical direction on the inner peripheral surface of the lower part of the crushing container 101. And a rotary disk 112 rotatably supported by the receiving member 102, and two rotary blades 113 symmetrically mounted on the upper surface of the rotary disk 112 at the center of the rotary disk 112. .

The rotary disk 112 has a fixed blade 1 at its edge.
The size of the diameter is set so as to be close to the blade edge of 11, and the rotary blade 113 also similarly has the rotary disk 112.
It is fixedly mounted on the rotating disk 112 so that its blade tip is close to the blade tip of the fixed blade 111.

As a result, the rotary disk 112 and the fixed blade 11
A gap of a predetermined size is formed between the receiving member 1 and the receiving member 1
It is designed to run down to the 02 side.

The drive means 120 is a drive motor 12.
1, a drive pulley 122 provided on the drive shaft of the drive motor 121, a driven pulley 123 connected to the rotary disk 112 via the rotary shaft, and a power transmission for interlocking the drive pulley 122 and the driven pulley 123. The belt 124 and the belt 124 are configured to transmit the rotational force from the drive motor 121 to the rotating disk 112.

A conventional crushing device 100 having the above-mentioned configurations
In the crushing operation of the residue, the driving means 120 urges the rotating disk 112 and the rotary blade 113 to rotate, and then the residue is charged from above the crushing container 101.

The residue is crushed by the rotating blade 113 in a rotating state and is subdivided so as to be crushed between the rotating blade 113 and the fixed blade 111. It flows down from the gap of the groove of 111 and the gap formed between the fixed blade 111 and the rotary disk 112 to the lower receiving member 102, and is guided to the discharge pipe 103 by this receiving member 102.

Usually, a storage container is prepared downstream of the discharge pipe 103, and the finely divided residue stored in the storage container is transferred to a stirring tank described later.

Next, a conventional stirring tank 150 will be described with reference to FIG.

The stirring tank 150 has a residue input port 151.
A tank main body 151 provided with A and a discharge port (not shown), a stirring blade 153 rotatably mounted inside the tank main body 151 via a rotating shaft 152, and a rotating operation of the rotating shaft 152. It is composed of a rotation driving means 160. Further, reference numeral 151B is an inlet port 15 of the tank body 151.
It is a manual type open / close lid equipped in 1A, and 151C is
It is an exhaust port for discharging water vapor in a tank body 151 described later.

The stirring blade 153 has a rotating shaft 152.
It is formed in a spiral shape centered on. The rotary shaft 152 has one end protruding outside the tank body 151, and the driven pulley 161 is fixedly mounted on the one end.

That is, the driven pulley 161, a main driving pulley 164 that is interlocked via a driving belt 162, and a drive motor 163 that urges the main driving pulley 164 to rotate.
The rotation driving means 160 is composed of

In this stirring tank 150, the residue finely divided by the above-mentioned crushing device 100 is charged into the tank main body 151 from the charging port 151A, and the stirring blade 153 is urged to rotate by the rotation driving means 160. Be stirred. By this stirring, the water content in the residue is equalized over the whole, and then calcium oxide (CaO) is added into the tank main body 151. This CaO has the property of reacting with the water in the residue to generate heat.
The stirring is continuously performed so that the water is evenly distributed in the tank body 151.

After the stirring operation is continued for a certain period of time,
The residue in the tank body 151 is left in a heated state. As a result, the residue that has become exothermic due to CaO becomes water vapor as a result of this exotherm and is discharged from the exhaust port 151C to the outside of the tank body 151, and by the time the reaction of CaO is complete, the volume of the residue is reduced. , Is reduced according to the amount of evaporated water.

That is, the conventional crushing apparatus 100 and the stirring tank 150 can reduce the amount of the residue, which is an organic waste such as raw garbage, from the original amount. In addition to this, since the water content in the residue is removed, the decay of the residue is slowed down and the generation of spoilage odor is suppressed.

[0019]

However, in the above conventional example, since the crushing device and the stirring tank are independent, the work of transferring the residue crushed by the crushing device to the stirring tank is manually performed. Had to do.

That is, since it is necessary to artificially perform the work of transporting the storage container in which the subdivided residue is stored to the stirring tank and the operation of transferring it into the tank main body of the stirring tank, The time spent for the drying operation with the heating agent and the work efficiency are poor, which is not suitable for treating a large amount of residue.

Furthermore, in addition to this, in the conventional crushing apparatus described above, when the residue is crushed, the residue on the rotating disk may escape upward due to the rotation of the rotary blade. However, it is difficult for the residue to enter between the fixed blade and the rotary blade, the crushing is not performed well, and excessive time is consumed for the crushing operation. In other words, the slowdown of the entire work due to this has been a problem.

The lower opening of the cylindrical member 21A has a shape that expands outward as it approaches the fixed blade 22, depending on the size of the fixed blade 22. The skirt portion of this spread can prevent the residue from escaping above the fixed blade 22 and the rotary blade 24 during the crushing operation.

A bottom member 21B is disposed further below the cylindrical member 21A with the fixed blade 22 interposed therebetween. The bottom surface member 21B is formed in a dish shape having substantially the same size as the lower end portion of the cylindrical member 21A, and functions as a tray for the crushed residue. Then, as shown in FIG. 1, a discharge port 21F communicating with a tank body 31 of the stirring tank 3 described later is provided in the right portion of the inner bottom surface of the bottom member 21B. Further, the inner bottom surface of the bottom surface member 21B is formed in a circular shape, and a rotary shaft 25B for transmitting a rotational force to the rotary disc 23 is rotatably held at the center thereof.

Next, based on FIGS. 1 and 3, the fixed blade 2
2 will be described. The fixed blade 22 is formed in a ring shape whose inner diameter is set to be substantially equal to the diameter of the lower end portion of the cylindrical member 21A described above. A plurality of groove-shaped blade edges 22A are uniformly formed on the inner surface thereof.

Inside the fixed blade 22, a rotary disk 23 equipped with a rotary blade 24 is disposed, and the above-mentioned groove-shaped blade edges 22A have the same center axis as the rotary disk 23. It is formed in a spiral shape. That is, each cutting edge 22
As shown in FIG. 1, A is formed uniformly along a direction that is slightly inclined with respect to the vertical direction.

Here, the rotating disk 23 is always urged to rotate in a fixed direction during the crushing operation (direction of arrow R in FIG. 3). As shown in FIG. 3, each blade tip 22A of the fixed blade 22 has a bottom surface of the crushing container 21 by rotation in the R direction so that the residue is effectively wound around the rotary blade 24 and the fixed blade 22 in accordance with this rotation direction. It is formed so as to follow the spiral S directed toward the member 21B side (that is, downward).

FIG. 4A shows the upper surface of the rotary disc 23. Further, FIG. 5 shows the shape of the blade edge 24B of the rotary blade 24 as viewed in the direction of the arrow in FIG. That is, on the upper surface side, two rotary blades 24 are installed symmetrically with respect to the center of the rotary disc 23. Each rotary blade 24
Has a configuration in which its blade edge 24B is inclined so as to follow a spiral in a direction opposite to that of each blade edge 22A of the fixed blade 22. As a result, during the crushing operation, the rotation of the rotary blade 24 urges the residue colliding with the blade edge 24B toward the bottom surface of the crushing container 21.

The rear end of each rotary blade 24 is rotatably engaged with the rotary disc 23 via a locking pin 24A. Therefore, normally, when the residue is crushed, the rotating disk 23
As a result of the centrifugal force generated by the rotation of the
The blade edge 24B is in a state of facing outward so as to face the fixed blade 22. Then, for example, when a large lump of residue is sandwiched between the fixed blades 22 and the rotary blades 24, the rotation of the rotary blades 24 widens the spacing between the rotary blades 24 and the fixed blades 22. This prevents the unrotatable state due to the entrainment.

FIG. 4C shows the lower surface side of the rotary disk 23. The lower surface side of the rotating disk 23 closely faces the bottom surface of the crushing container 21, and the lower end of the rotating disk 23 is slid from the lower surface of the rotating disk 23 to the bottom surface of the bottom member 21B of the crushing container 21 ( Alternatively, the cleaning blade 27 is provided so as to be suspended (in a state where the cleaning blade 27 is brought close to the cleaning blade 27).

Each of the cleaning blades 27 has a tip portion that slides on the bottom surface member 21B as the rotary disk 23 rotates, so that the bottom surface member 21
The crushed residue accumulated in B is forcibly sent from the outlet 21F to the stirring tank 3 side.

Below the crushing container 21, the rotation driving means 2 is provided.
5 are provided. The rotation driving means 25 is rotatably mounted in the center of the bottom member 21B of the crushing container 21 and transmits a rotational force to the rotating disc 23.
And a drive motor 25A for urging the rotary shaft 25B to rotate. With these configurations, the rotating disk 23 and the rotary blade 24 are urged to rotate during the crushing operation.

Next, the stirring tank 3 will be described. The stirring tank 3 is installed adjacent to the crushing means 2 as shown in FIG. Further, FIG. 6 is a sectional view showing the overall configuration of the stirring tank 3.

As shown in FIG. 6, the stirring tank 3 is provided with a receiving port 31A for receiving the residue crushed by the crushing means 2 through the discharge port 21F of the crushing means 2 and a tank for storing the crushed residue. The main body 31 is mainly composed of a stirring mechanism 40 for stirring the residue inside the tank body 31, an exhaust mechanism 80 for exhausting water vapor and the like in the tank body 31, and a heater 60 for heating the tank body 31. ing.

Hereinafter, each part will be described in detail with reference to FIG. First, the tank main body 31 is a housing that accommodates the crushed residue inside, and a rotatable opening / closing lid 32 is provided on the upper portion thereof via a packing 33. This open / close lid 32

Then, as shown in FIG. 6, when the opening / closing lid 32 is opened, the entire upper surface of the tank main body 31 is opened, and the heating agent is supplied during the stirring operation and the inside of the tank main body 31 after the stirring operation is performed. When the cleaning is performed, the opening / closing lid 32 is opened. Also, usually
At the time of the stirring operation, the opening / closing lid 32 is closed, and in combination with the effect of the packing 33, the structure is such that the malodor generated from the residue inside does not leak to the outside.

Further, as shown in FIG. 8, the opening / closing lid 32 has a roof type structure composed of two inclined surfaces,
A groove 32A for guiding a water droplet is provided along one side below each of the inclined surfaces (not shown in FIGS. 2 and 6). The water drop guide groove 32A is connected to a water tank of an exhaust mechanism 80 described later by a pipe 32B, and water drops adhering to each inclined surface pass through the water drop guide groove 32A and the pipe 32B. You will be guided to. That is, with these structures, the water droplets generated by the later-described residue drying operation and attached to the opening / closing lid 32 are effectively removed from the inside of the tank body 31, and the water droplets are not efficiently returned to the residue and can be dried efficiently and quickly. You can

Further, at the bottom of the tank main body 31, a discharge port 31B for discharging the residue after all the treatments are provided. A movable door that can open and close the discharge port is provided outside the discharge port 31B, but the illustration thereof is omitted here.

Here, FIG. 7 shows a sectional view of the tank main body 31 as viewed from the right side in FIG. Inside the tank main body 31, a rotary shaft 41 of a stirring mechanism 40 described later is horizontally arranged. Reference numeral 31C is an engaging hole into which one end of the rotary shaft 41 is inserted, and the sectional shape of the tank body 31 below the engaging hole 31C is formed in a semicircular shape as shown in FIG. There is. That is, the lower half of the tank body 31 is formed in a semi-cylindrical shape.

This is because the stirring blade 51 fixedly mounted on the rotating shaft 41, which will be described later, is formed in a shape corresponding to the locus of the tip end portions thereof when rotating with the rotating shaft 41. Due to the shape of the tank body 31, the residue accumulated in the lower portion of the tank body 31 is uniformly stirred by the stirring blade 51 effectively.

Next, the stirring mechanism 40 will be described in detail. The stirring mechanism 40 includes a rotating shaft 41 arranged rotatably in the horizontal direction inside the tank body 31, a plurality of stirring members 51 fixedly mounted on the rotating shaft 41 and rotating, and a rotating shaft 4.
1 and a rotary drive means 42 for urging the rotary operation.

Both ends of the rotary shaft 41 are supported on the wall surface of the tank body 31 via bearings, and one end of the rotary shaft 41 is connected to the rotation drive means 42 arranged outside the tank body 31. Engaged.

The rotary drive means 42 includes a driven gear 43 mounted on one end of the rotary shaft 41, a main driving gear 44 for transmitting a rotational force to the driven gear 43, and a drive motor 45 equipped with the main driving gear 44. During the stirring operation, the driving motor 45 urges the rotary shaft 41 to rotate via the main driving gear 44 and the driven gear 43.

Further, the rotating shaft 41 is fixedly equipped with a stirring member 51 at a substantially central portion in the axial direction, and one stirring member 51 is provided on each side of the stirring member 51. Each is fixedly equipped. All of these stirring members 51 are fixedly mounted perpendicularly to the rotary shaft 41, and the central stirring member 51 and the two stirring members 51 at both ends sandwich the rotary shaft 41 and the tip portions thereof are opposite to each other. It is arranged facing. The stirring member 51 has a T-shaped tip, and the smooth surface of the tip is rotated by contact with the inner wall of the semi-cylindrical portion of the tank body 31 by the rotation of the rotating shaft 41. The residue in the tank main body 31 is stirred by.

Next, the exhaust mechanism 80 will be described. In this stirring tank 3, the crushed residue is stirred, and the water content in the residue is made uniform throughout the residue, and then calcium oxide (CaO) is added to the residue. Then, since the heat of reaction generated by the reaction between this CaO and the water in the residue removes the water in the residue itself, the water vapor generated at that time must be exhausted from the inside of the tank body 31 to the outside. In the case of such exhaust, an exhaust mechanism 8 is provided in order to prevent a bad odor, a strange odor, etc. generated from the residue from leaking to the outside.
0 is provided.

The exhaust mechanism 80 has an exhaust pipe 81 drawn from the inside of the tank body 31 and communicating with the outside, a water tank provided in the middle of the exhaust pipe 81, and forcibly urging the exhaust pipe 81 to evacuate the exhaust gas. And an exhaust pump (each part is not shown) which is exhausted, and is arranged so that steam or the like in the tank body 31 to be exhausted always passes through the water in the water tank on the way. That is, with this configuration, it is possible to dissolve components causing causative odors or the like in water vapor into water and reduce the generation of malodors due to exhaust. In addition, you may put the liquid which has a component with which the bad odor removal effect is higher than water in a water tank.

Next, the heater 60 will be described.
The heater 60 is composed of a heating element that is uniformly provided on the outer peripheral surface of the semi-cylindrical portion of the tank body 31 (excluding the periphery of the discharge port 31B of the tank body 31) to generate heat by energization and an energizing circuit thereof. To be done.

Inside the tank main body 31, the residue is heated by the addition of the heating agent as described above. Therefore, by uniformly heating the tank main body 31 from the outside by the heater 60, the reaction between the heating agent and the moisture in the residue is activated, and the moisture in the residue is directly removed by the heating. Combined with this, the effect of removing water in the residue is synergistically enhanced, and the work can be performed more quickly.

Further, reference numeral 70 shown in FIG. 6 indicates a drive motor 25A of the rotation driving means 25 of the crushing means 2 and the stirring tank 3.
Is a control circuit for controlling the operation of each part such as the drive motor 45 of the rotation driving means 42, the exhaust pump of the exhaust mechanism 80, the heater 60, and the like. The control circuit 70 drives the above-described units in a predetermined order in accordance with an input signal from an operation panel (not shown) provided outside the agitation tank 3, and controls the operation based on a set predetermined time. Has become.

The operation of the residue treatment apparatus 1 having the above-mentioned configurations will be described. First, the drive motor 25 of the rotation drive means 25
The rotational force is applied to the rotary disk 23 and the rotary blade 24 by A. Then, the residue is charged from above the crushing container 21. The introduced residue is struck by the blade edges of the rotary blades 24 in a rotating state, the rotational action is urged by the rotary disk 23, and the blade blades 22A of the fixed blade 22 subdivide the blades.

The finely divided residue flows down from the gap between the fixed blade 22 and the rotary disc 23 to the bottom member 21B side of the crushing container 21, and is discharged from the bottom surface of the bottom member 21B by a plurality of cleaning blades 27 to the discharge port 21F. Through the stirring tank 3
Is sent to the tank body 31 side.

When all the residues in the crushing container 21 are subdivided and sent into the tank body 31 of the stirring tank 3, the subdivided residues are stirred in the stirring tank 3. Initially, CaO is not added and only the residue is stirred. This stirring is performed in order to make the water content in the residue uniform throughout the residue. That is, the rotational force is applied from the drive motor 45 of the rotary drive means 42 to rotate the rotary shaft 41.

With the rotation of the rotary shaft 41, the stirring roller 52 and the stirring blade 51 stir the residue. When this stirring operation is performed for a certain period of time, the opening / closing lid 32 is opened and CaO is added to the residue. After the addition of CaO, the opening / closing lid 32 is closed again, and the residue is continuously stirred for a certain period of time. As a result, the added CaO spreads throughout the residue, and the stirring operation is stopped when the time is right.

At the same time as (or in advance of) the addition of CaO, the heater 60 is driven to heat the residue inside the tank main body 31, thereby promoting the reaction between the water contained in the residue and CaO. As a result, the generation of reaction heat is activated, and due to the synergistic effect with the heating action of the heater 60, the moisture contained in the residue is removed from the residue.

Further, simultaneously with the addition of CaO, the exhaust pump of the exhaust mechanism 80 is driven to constantly exhaust the water vapor in the tank body 31.

Further, the water droplets adhered to the opening / closing lid 32 due to the water vapor generated from the residue flow down to the water droplet guiding groove 32A along the inclined surface thereof, and further, the water droplet guiding groove 3 is formed.
It is guided from 2A to the water tank of the exhaust mechanism 80 via the pipe 32B.

Then, when a predetermined time has passed since the addition of CaO, the residue is removed of the water content, and the tank main body 31 is removed.
Is discharged from the discharge port 31B.

As described above, according to this embodiment, the residue such as raw garbage is subdivided and the contained water is removed, so that the amount of the residue can be effectively reduced from the original amount. In addition to this, since the water content in the residue is removed, the progress of the decay of the residue can be slowed down and the generation of a spoiled odor can be suppressed, and the adverse effect on hygiene can be eliminated. is there.

Further, in the present embodiment, the residue treatment apparatus is provided with a crushing mechanism for crushing the residue and a stirring tank for stirring, and the residue finely divided by the crushing mechanism moves to the tank body of the stirring tank. Therefore, it is possible to improve work efficiency by eliminating manual work for transporting the residue.

Further, since the shape of the cutting edge of the fixed blade of the crushing mechanism is formed along the spiral in the direction toward the bottom side of the crushing container by rotating in the same direction as the rotating disk, it is put into the crushing container. Since the residue does not escape above the rotating disk and is effectively crushed along the direction of the blade edge of the fixed blade, the residue can be efficiently and quickly subdivided.

Further, since the blade edge of each rotary blade is inclined along the spiral opposite to the blade edge of the fixed blade, the residue that collides with the blade edge of this rotary blade due to the rotation will be on the bottom surface side of the crushing tank. The movement is effectively urged, the upward movement of the residue is prevented, and the residue can be subdivided more efficiently and quickly.

Furthermore, since the cylindrical member of the crushing container of the crushing mechanism has a shape that spreads toward the bottom surface, the residue crushed by the rotary blade and the fixed blade is blocked at the hem of the expansion of the cylindrical member. Therefore, the crushing work can be carried out more favorably.

Further, since the lower surface of the rotating disk is equipped with the cleaning blade, the residue crushed on the bottom surface of the crushing container does not stay and is always transferred satisfactorily to the stirring tank.

[0081]

According to the first aspect of the present invention, since the crushing mechanism is provided with the crushing mechanism for crushing the residue and the stirring tank for stirring, and the crushing container is connected to the stirring tank through the discharge port, The subdivided residue moves to the tank body of the stirring tank,
It is possible to improve the work efficiency by eliminating the manual work for transporting the residue between the separate crushing device and the stirring tank as in the conventional case. Therefore, a series of operations such as fragmentation and agitation by crushing the residue and drying by addition of CaO are continuously performed, and these operations can be speeded up.

Further, since the shape of the cutting edge of the fixed blade of the crushing mechanism is formed along the spiral in the direction toward the bottom side of the crushing container by the rotation in the same direction as the rotating disk, it is put into the crushing container. Residue is sent along the direction of the blade edge of the fixed blade without escaping above the rotating disk, and is effectively crushed by the fixed blade and rotary blade, so the residue can be crushed efficiently and quickly. You can

The invention according to claim 2 has the same effect as the invention according to claim 1, and since the shape of the blade edge of the rotary blade is inclined along the spiral in the direction opposite to the blade edge of the fixed blade, The residue crushed along the blade edge is prevented from escaping upward while being urged to move to the bottom surface side of the crushing tank, and the residue crushing work can be performed more efficiently, quickly and effectively.

According to the invention of claim 3, claim 1 or 2
In addition to having the same effect as the described invention, the ceiling portion of the stirring tank is tilted and a groove for guiding water droplets is provided along one side that is downward due to the tilt to discharge the water droplets that adhere to the outside of the stirring tank. Therefore, the water generated from the residue does not return to the residue again, and the residue can be dried effectively and efficiently, which makes it possible to speed up the entire processing operation of the residue.

The invention according to claim 4 has the same effect as the invention according to claim 1, 2 or 3, and since the stirring tank is equipped with a heater, the stirring tank is heated by the heating heater. When CaO of the residue in the residue is added, the reaction between the heating agent and the water in the residue is activated, and in addition to the effect of directly removing the water in the residue by heating, synergistically, The removal effect is enhanced, and it is possible to more efficiently and quickly remove residual water.

Therefore, it is possible to further reduce the volume of the residue as compared with the conventional case. Specifically, the volume reduction effect of about 30% can be obtained only by heat generation due to the addition of CaO, but according to the present invention, the volume of 50% or more of the residue can be reduced. As a result, it is possible to prevent a large amount of organic waste such as raw garbage from being generated.

The present invention is constructed and functions as described above, and by doing so, it is possible to provide an excellent residue treatment apparatus that has never been obtained.
