Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a concrete structure of a garbage storage machine in which an air cooling device is disposed above the garbage inlet of the garbage storage machine.

[Conventional technology]

In general, in restaurants, hotels, buildings, hospitals, etc., a large amount of garbage such as kitchen waste, filth, empty bottles, etc. is handed over to garbage collection trucks that regularly patrol in order to dispose of it hygienically and efficiently. Currently, waste storage machines are used to temporarily store waste inside buildings.

With the spread of such garbage storage machines, the volume of the garbage can be kept small, and scattering by livestock and small animals as well as the generation of putrid odors can be reasonably prevented.

By the way, as such a device, for example,
"Garbage storage device" of Jitsukai 57-141901, Jitsukasho
58-67802's ``garbage storage and discharge device'' has been devised.

[The problem that the idea aims to solve]

However, in the case of the "garbage storage and discharge device" of Utility Model Application No. 58-67802, since the screw 17 pushes the garbage into the drum, the screw 17 is easily wrapped around the garbage. The entangled dirt acts as resistance, weakening the rotation of the screw 17 and preventing its function from being fully exerted, making it difficult to push the dirt smoothly into the drum.

In addition, the ``garbage storage and discharge device'' of Utility Model 1986-67802
Because the structure is such that garbage is pushed into the drum from the bottom, the garbage accumulated at the bottom of the drum gets in the way.
It becomes difficult to push the dirt smoothly into the drum. In order to resist the accumulated garbage and push the garbage further into the drum, the horsepower of the screw 17 must be increased.
There is a problem in that the size of the driving mechanism and the drive mechanism of No. 7 are increased.

Furthermore, looking at the structure of commonly used garbage storage machines, the main focus is on compacting the garbage itself to make it smaller, and the work of loading the garbage into the garbage storage machine prioritizes only transporting it to a garbage collection vehicle. In reality, the working environment of employees is largely ignored.

To put this in concrete terms, especially in the summer when room temperature is high, the area near the garbage storage machine is filled with a rotting odor.
Also, even in winter, the internal fermentation heat of the garbage itself causes considerable discomfort, although it is milder than in summer.

As a specific countermeasure, liquid or powder deodorizer is sprayed into the input slot along with the garbage, but workers have to store the deodorizer, transport it to the storage machine, and then spray it. However, it is still unsatisfactory in terms of working environment and economy, as not only does the labor burden increase, but also the purchase cost of the deodorizer itself and the storage space are required. The structure of the loaded drum input port having a tapered shape has a drawback that it is difficult to counteract this problem.

The present invention was devised in view of the above-mentioned problems and to solve the problems. To provide a garbage storage machine that eliminates bad odors, reduces the discomfort caused by odors experienced during work, and can smoothly put the garbage into the drum by moving the thrown garbage upwards and then putting the garbage into the drum. It's about doing.

[Means for solving problems]

In order to achieve the above objectives, this device is surrounded by a hollow casing B, which is rotatable within the casing B, and inside which a plurality of compression vanes Bl are disposed, one side of which is a body part. A drum D having an input port opening to the same diameter as the drum D and a discharge port opening on the other side, a rear surface opening fixed to one side of the drum, and a plurality of crushing blades Bb on the inner circumferential side thereof, a garbage crushing section Sb having a cylindrical shape with an open front surface, having a diameter larger than the drum and rotating integrally with the drum;
The casing B is arranged in front of the garbage crushing section Sb and has an input frame E provided with a lid plate L below the casing B.
The garbage crushing section Sb has a semicircular rear surface b, and a lower portion with an outer diameter that maintains a small gap between the crushing blades Bb on both sides of the front of the rear surface. A crushing plate c exhibiting an arc shape that opens
A crushing tool Pb is fixed to the inside of the cover plate P, and an upper surface a that is inclined toward the inner side and lower side of the drum is fixed to the inside of the cover plate P, and an air cooling device Rf is fixed to the upper side of the cover plate P. , a garbage lift rotating upward is placed in a small gap between the fixed outer circumferential side of the arc-shaped crushing plate c and the inner circumferential side of the garbage crushing section Sb rotating on the outside of the crushing plate c and the crushing blade Bb. Small chambers Sc for garbage lifting are formed one after another, and the small chamber Sc for raising garbage is configured to upwardly transport the garbage inputted from the input frame E to above the crushing tool Pb.

〔Example〕

Hereinafter, the present invention will be described in more detail based on embodiments shown in the drawings.

The drawings show one embodiment of the present invention.
The figure is a partially cutaway center sectional view in the longitudinal direction of the garbage storage machine, and FIG. 2 is a right side view of FIG. 1.

In Fig. 1, D is equipped with a plurality of compression blades Bl for crushing and transporting garbage on its inside, and its discharge port side (left side in the figure) has a smaller diameter, and its input port side (right side in the figure) has a smaller diameter. It is a drum with an opening that has the same diameter as the body.
Sb is a garbage crushing part having a cylindrical shape with a diameter larger than the drum D, and a through hole smaller than the outer diameter of the drum D is bored on the rear surface, and a through hole smaller than the outer diameter of the drum D is bored on the front surface. The hole has a diameter of approximately
(see figure) is fixed.

B is a hollow housing that covers the drum D and the garbage crushing section Sb, and its front and rear surfaces are covered with cover plates P and P' as shown in FIG.

Reference numeral E denotes a charging frame E that is provided with a cover plate L that can be opened and closed below a cover plate P on the front surface. Rf is an air cooling device disposed above the input frame E, and for example, a cooling mechanism is installed below the air cooling device, and cooling air is discharged from the upper back surface of the air cooling device.

Now, Pb is a crushing tool fixed to the front cover plate P, and the front view is shown in Figure 3A, and the side view is shown in Figure 3B.
As shown, on both front sides of the semi-circular rear surface b, there is an arc shape with an open bottom, which is disposed concentrically with the garbage crushing part Sb having an outer diameter that maintains a small gap with the crushing blade Bb. A crushing plate c is formed, and its upper surface a is formed so as to be inclined downwardly inside the drum D, and the top of the upper surface a has a notch in which the rear part of the air cooling device Rf is fitted. K is formed.

Then, in a small gap between the fixed outer circumferential side of the arc-shaped crushing plate c, the inner circumferential side of the garbage crushing part Sb rotating on the outside of the crushing plate c, and the crushing blade Bb, a garbage lifting device that rotates upward is provided. Small chambers Sc are formed sequentially.

In FIG. 1, R indicates rollers for rotating the drum D, which are disposed on both outer sides of the drum D in the vicinity of its front and rear ends. M indicates a motor that drives a pinion that meshes with a rack fixed to the outer circumference of the drum D. S indicates a base on which the proposed garbage storage machine is placed. Sr indicates a pulley stand for transporting garbage arranged at the rear of the housing B. g indicates a gasket that closes the gap with the cover plate P.

[Effect of idea]

The present invention consists of the configuration described above, and then:
Describing the effects based on the configuration of the present invention,
Unlike conventional models, where the input side of the drum D is tapered, the input side of the drum D has an opening with the same diameter as the body of the drum, and a garbage crusher with a diameter larger than that of the drum. part Sb is fixed,
Furthermore, since the cover plate P fixed to the casing B is disposed on the front surface of the cover plate P, that is, the garbage input port side is positively widened, so that the cover plate P is fixed to the front surface of the input port side. Since the covered plate P has ample area, an air cooling device Rf with sufficient cooling capacity can be fitted above the input frame E, and therefore the drum D can be sufficiently cooled before loading the garbage. When the work is carried out in this state, the input waste is stirred by the compression blade Bl in the drum, and the cooling air is sufficiently absorbed to cool it down one by one, so the generation of fermentation heat can be suppressed as much as possible. .

Therefore, there is no need to use a deodorizer like in the conventional type, and there is no need to worry about putrid odors during work, which reduces labor and makes the work easier. The maintenance cost of the storage machine itself can also be reduced.

Coupled with these effects, since the garbage is carried upwards and introduced into the drum D from above, the drum D is
The garbage container is hardly obstructed by the accumulated garbage inside the drum D, and the garbage can be smoothly put into the drum D. Thus, the purpose of the present invention can be fully achieved. It has an effect.

In the above explanation, it has been stated that the air-cooling device Rf has an internal structure that has a cooling mechanism below and discharges cold air from the upper back surface, but this is not limited to this, and the internal structure is not important as long as it can be placed here taking into consideration the area of the cover plate P. Based on experiments, it is desirable to have an air-cooling capacity of approximately 1400 [Kcal/H] per ⁵ m3 of waste volume in the drum.
