BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a food waste disposer which improves the agitation efficiency of food waste or food waste with a decomposing medium agent or microbial powder to improve the processing efficiency.

[0002]

2. Description of the Related Art As global environmental protection is called for,
As a method of disposing of a large amount of daily garbage that is discharged daily without resorting to landfilling or heat treatment and decomposing and disposing of it, the garbage disposal method applying the degrading action of microorganisms has been attracting attention. If garbage is left in the soil for a few months and left for several months, the microorganisms in the soil will decompose the garbage cleanly, which decomposes into water and gases such as carbon dioxide and methane (gasification). The bio-based garbage processor is an industrial application of the principle of decomposition by microorganisms. This type of bio-based food waste disposer usually uses bacteria called "aerobic bacteria" that have a major oxidizing effect as a decomposing agent, but in addition to aerobic bacteria, it has a unique function for decomposition. It has also been confirmed that by mixing well-balanced "facultative anaerobic bacteria" and "anaerobic bacteria", etc., the decomposition of food waste can be promoted and decomposed quickly.

[0003] For example, a bio-based food waste processing machine which is commercially available for commercial use, firstly, in a processing tank equipped with a stirring blade,
An aerobic bacterium, a facultative anaerobic bacterium, or a microbial powder in which an anaerobic bacterium and an enzyme are mixed in a well-balanced manner is mixed with a degrading medium agent such as wood chips to form a degrading soil. Next, put garbage into the tank from the upper part of the treatment tank and rotate the stirring blade while controlling the supply and exhaust while keeping the temperature inside the tank at the optimum temperature, so that the garbage and the decomposition medium agent and microbial powder are evenly contacted. stir. At this time, the decomposition medium agent plays a role of maintaining temperature and humidity and assists oxygen supply to aerobic bacteria, so that an optimal environment for the activity of microorganisms is created and decomposition of food waste is promoted.

DISCLOSURE OF INVENTION Problems to be Solved by the Invention In the above-mentioned conventional food waste disposer, food waste is put into a processing tank containing a decomposition medium agent and microbial powder, and the agitating blades are rotated to separate food waste and garbage. The decomposition medium agent or raw garbage and the microbial powder are stirred, but the stirring blade rotates while scraping the raw garbage in the tank, but the garbage scraped up by the stirring blade is simply the passage of the stirring blade, that is, It is often only stirred to make a way in the rotating space of the stirring blade, and when the entire mixture of the decomposition medium agent and food waste is viewed as a mass of sediment, the stirring blade moves this deposit along the rotating space. If it only has the effect of cutting into slices, the effect of mixing raw garbage and microbial powder by stirring,
There is a problem that the heat retention and moisturizing effect of the decomposition medium agent and the contact effect between the microbial powder and the air are not improved, and the treatment efficiency is not obtained, so that the treatment takes time.

On the inner wall of the upper surface of the cane sig 2, an air supply duct 12 for supplying the outside air into the processing tank 3 and an exhaust duct 13 for exhausting the gas in the processing tank 3 are provided side by side. The interior can be ventilated intermittently or continuously.

The processing tank 3 installed in the cane sig 2 is
The front panel 14 and the rear panel 15 facing each other with a certain distance in the front and rear are coupled via a bottom panel 16 having a U-shaped cross section, and the left and right openings of the front panel 14 and the rear panel 15 are connected to the side panels 17, 18. The structure is closed by. However, the upper surface of the casing 2 which communicates with the garbage input port 2b is completely opened. A warm heater 10 is assembled to the bottom panel 16, and the temperature controller 11 controls on / off of the warm heater 10 to control the temperature inside the tank to a predetermined temperature. A rotary drive shaft 19 that supports the stirring blade 8 traverses the central portion of the processing tank 3 in the longitudinal direction and is rotatably supported by inserting the side panels 17 and 18. A large-diameter sprocket 20 is fixed to the tip of the rotary drive shaft 19, and a transmission chain 22 is stretched between the large-diameter sprocket 20 and a small-diameter sprocket 21 fixed to the shaft of the geared motor 9. is there. Therefore, by pressing the start switch button provided on the operation panel 6 to drive the geared motor 9, the rotary drive shaft 19 can be slowly rotated together with the large diameter sprocket 20.
If the emergency stop button switch 7 is pressed, the rotation drive shaft 19 can be brought to an emergency stop by cutting off the power supply to the geared motor 9.

As shown in FIGS. 2 and 3, on the rotary drive shaft 19, there are formed large-diameter hubs 19a at different positions in the longitudinal direction, and the rotary blades 8 are respectively formed on these hubs 19a. It is attached. The rotary vane 8 is configured by inserting and holding rods 25 with fins 24 into two hollow support pipes 23 extending in opposite directions from the hub 19a. Of the five sets of support pipes 23, the support pipes 23 supported by the hubs 19a located at both ends of the rotary drive shaft 19 are in phase, and the support pipes 23 supported by the inner hubs 19a are the support pipes 23 at both ends. The phase is advanced by 45 degrees with respect to. Further, the support pipe 23 fixed to the hub 19a located at the center is attached to the support pipes 23 at both ends with a predetermined angle phase delay.

The fins 24 play the role of paddles for agitating food waste, etc., and have a flat plate shape and are fixed by welding to the tips of the rods 25. The distal end of the rod 25 is rotatably inserted into the support pipe 23, and as shown in FIG. 4, the mounting posture is fixed by a fixing screw 26 that penetrates the support pipe 23. Therefore, by temporarily loosening the fixing screw 26, adjusting the distance from the center of the rotary drive shaft 19 to the tip of the fin 25 or the direction of the fin 25, and then tightening the fixing screw 26 when a desired posture is obtained, The rotation posture and the rotation trajectory of the fin 25 can be arbitrarily adjusted.

By the way, in order to regulate the movement space of the garbage inside the tank, four projections 27 are arranged in a horizontal line on the front panel 14 and the rear panel 15 of the processing tank 3. Protrusion 27
Is a flange portion 2 fixed to the inner wall of the processing tank 3 with screws.
7a and a tongue portion 27b integrally formed on the flange portion 27a. The fins 24 are attached in such a positional relationship that they cross a position separated from the tongue portion 27b by a certain distance. A cylindrical marker bar 28 is provided on the end surface of the processing tank 3 so as to indicate the upper limit height of the decomposition medium agent in the processing tank 3, while being agitated by the fins 24 like the projection 27. It is responsible for regulating the space for moving garbage.

Here, in the case of treating food waste, the food waste is put into the treatment tank 3 containing the decomposing medium agent and the microbial powder, and the agitating blade 8 is rotated to mix the garbage and the garbage and the decomposing medium agent. Alternatively, stir the garbage and the microbial powder. The stirring blade 8 rotates while scraping off the garbage and the like in the tank, but at that time, since the projection 27 partially blocks the course of the garbage scraped up by the stirring blade 8, the movement space of the garbage is the projection 27. Regulated by. For this reason, the stirring is not so effective as to make a way in the rotating space of the stirring blade 8 and not between the garbage that is restricted by the protrusion 27 and the portion that is scraped up by the stirring blade 8. By causing a large amount of shearing, the food waste, the decomposition medium agent and the microbial powder can be stirred extremely well. As a result, the mixing effect of raw garbage and microbial powder by stirring, the heat retention and moisturizing effect of the decomposition medium agent, and the contact effect between microbial powder and air are very high, and the treatment time is shortened because high treatment efficiency is obtained. It

As a concrete example, for example, 100 liters of a decomposition medium agent and 300 microbe powders are first put in the treatment tank 3.
After adding gram and stirring to create an environment suitable for the activity of microorganisms, if 10 grams of garbage and microbial powder are continuously added every day, the introduced garbage is decomposed and digested cleanly by microbial powder, Most can be converted to water and carbon dioxide. When 100 liters of degrading medium agent is used, a processing capacity of up to 15 kg of garbage per day can be obtained, and leftover food, fish, fried foods, vegetable leaves and the like can be cut in 3 to 8 hours, and shrimp and crab. It is decomposed in 1 to 1 and a half days in husks or meat and egg shells, and in 2 to 4 days in chicken bones and potatoes. Decomposition medium agent is a marker rod 2
When the crossing line indicated by 8 is crossed, it may be replaced with a new decomposition medium agent, and until then, garbage and microbial powder may be added and added every day. In other words, even if garbage is produced, it can be added each time if it is less than the amount that can be processed. Therefore, it is not necessary to store the garbage elsewhere, and therefore a hygienic environment can always be created.

As described above, according to the above-mentioned food waste processing machine 1, when the food waste introduced into the processing tank 3 is agitated by the agitating blades 8, the protrusions 27 protruding in the processing tank 3 are provided. By restricting the moving space for food waste, the food waste that was conventionally agitated simply in accordance with the rotation of the agitating blades is projected 27
Movement is restricted only to the part that hits the
Relative shearing occurs between the garbage that is restricted in movement by the stirring blade 8 and the garbage that is scraped up by the stirring blades 8. The greater the shearing, the greater the stirring effect, which is effective in decomposing the garbage. Since it is actively contacted with fresh air, it is possible to process food waste in a short time.

A flange portion 27a for fixing the protrusion 27 to the inner wall of the processing tank 3 by screwing, and a flange portion 27a.
Since the tongue portion 27b is integrally formed upright, the flange portion 27a is screwed to the inner wall of the processing tank 3 to dispose the tongue portion 27b in a predetermined positional relationship with the stirring blade 8. be able to. Further, by exchanging the protrusions 27 as appropriate according to the type of garbage and the amount to be processed, it is possible to make optimum settings according to the processing conditions.

Furthermore, the stirring blade 8 has a rotary drive shaft 19
A hollow support pipe 23 having one end fixed thereto, a rod 25 inserted into and held by the support pipe 23 so as to be rotatable, and a flat plate shape that is fixed to the rod 25 and crosses a position separated from the protrusion 27 by a predetermined distance. Since the fins 24 are provided, the length of the rod 25 and the direction of the fins 24 are adjusted with respect to the support pipe 23 fixed to the rotary drive shaft 19, so that the fins 24 and the protrusions 27 can be formed in accordance with the type and amount of food waste. The relative positional relationship of the projections 27 and the fins 24 fixed to the inner wall of the processing tank 3 can be adjusted freely.
The shape of the passage defined between and can be varied to always achieve the highest processing efficiency.

In the above embodiment, the protrusion may be formed by a boss portion integrally formed on the inner wall of the processing tank 3, and in this case, the space in which the stirring blade 8 is rotated faces a predetermined distance. By processing the inner wall of the processing tank 3 so as to be sandwiched by the relationship, the projection itself can be disposed integrally with the inner wall of the processing tank 3, so that no special parts for the projection are required. It is possible to simplify the process and reduce the manufacturing cost.

Further, in the embodiment, the case where the decomposing medium agent and the microbial powder are put into the treatment tank 3 in addition to the raw garbage and the mixture is stirred, however, only the raw garbage is put into the treatment tank. It is also possible to stir, and it is also possible to carry out the treatment with a combination of food waste and a decomposition medium agent or a combination of food waste and microbial powder.
