Description

[0001] Fermentation Equipment For Organic Waste [0002]

The present invention relates to a fermentation apparatus, and more particularly, to a fermentation apparatus for organic matter to be used for producing compost and the like by fermenting organic wastes such as food wastes.

The present invention relates to a fermentation apparatus for regenerating compost, feed or the like by using an organic material such as animal fats or food wastes. The present invention particularly proposes an improvement to the object to be treated which is provided around the stirring device installed in the fermentation device.

In the conventional fermentation apparatus, the stirring device for stirring the object to be processed uses an escalator moving along the fermentation tank (refer to Korean Patent Application No. 10-2006-0076282). In the past, a configuration in which this escalator is installed . Further, the organic material supplied to the fermentation tank is fed in one direction along the fermentation tank by a ladder operation or a screw conveyor type, and then discharged.

However, such a conventional fermentation apparatus has a structure in which continuous operation can not be performed. In other words, you can not build an automated line. This is because it is necessary to stop the supply of the organic material while providing the empty space by transferring the organic material supplied to the one side of the fermentation tank to the rear side.

Since the work must be performed intermittently as described above, the working efficiency is lowered.

On the other hand, the conventional material supply unit for supplying the organic material widely uses a method using a screw conveyor, which increases the installation cost and lowers the supply speed of the material.

On the other hand, in an industrial facility in which particulate matter such as sand, grains, etc. is fed by pressure using a tubular body, the conveying line is often damaged by the impact force of the particles. A conventional transfer line is a tubular body having a circular section, and a connecting tube (tubular body of an elbow type) having the same sectional shape at the bent portions is used. If this connector is damaged, it is necessary to separate and replace this part, which is too expensive. The reason is that the price of the connector is not too low and the replacement work is not easy.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The fermentation apparatus of the present invention is for producing a compost or a feed by fermenting an organic subject matter containing a fodder or food waste while stirring. Various kinds of subsidiary materials may be mixed into the to-be-processed product P, which will be referred to as a to-be-processed product P here because it is a known matter.

The fermentation tank 1 to be fermented is a rectangular rectangular tube having a predetermined depth and an open top. The fermentation tank 1 is usually formed of cement bricks and has a width of 6 to 10 m and a length of several tens of meters. The to-be-processed product P is introduced into one side of the fermentation tank 1 and is slowly transferred to the other side for several days to complete fermentation. The depth of the fermentation tank 1 may be 1 to 2 m. However, these numerical values are only examples for the sake of understanding, and do not limit the scope of the present invention.

The movable rail 3 is installed along the longitudinal direction W1 of the fermentation tank 1. [ The movable rail 3 can be seated on the side wall 5. The main moving table 7 is installed on the movable rail 3 so as to be movable along the movable rail 3. [

A pair of stirrers (9, 11) is seated side by side on the upper part of the main moving table (7). The stirrers 9 and 11 work to move the fermentation tank 1 along the direction indicated by the arrow A1 together with the main moving table 7 and to pour the material to be pushed forward and move it backward. The stirrers 9 and 11 reciprocate along the longitudinal direction W1 on the fermentation tank.

Since the stirrers 9 and 11 are of the escalator type and are known matters, the configuration thereof will be briefly described.

The agitators 9 and 11 are mounted on the main moving table 7 and include a chassis 15 connected to the moving rail 3 through a wheel 13 and a chassis 15 And the other end of the conveyor 17 or 17 'is lifted or lowered by the conveyor 17 or 17', and the other end of the conveyor 17 or 17 ' ') Adjacent to the bottom of the fermentation tank (1) or spaced therefrom. The conveyor lifting means can be hydraulic cylinders 19, 19 '. The conveyors 17 and 17 'are provided with a chain 26 that runs along the feed surface 21 in an endless track manner by a lifter 22 that provides a feed surface 21 and sprockets 24 that are provided on both sides of the lifter, And a bucket (23). The bucket 23 feeds the object P piled up in the fermentation tank 1 along the inclined transport surface 21 and sends it backward (see FIG. 2).

When the agitators 9 and 11 are moved in the direction of the arrow A2 and returned to the original state, the conveyors 17 and 17 'are held so as not to touch the article P (see the one-dot chain line in FIG. 2 ).

According to the embodiment of the present invention, the pair of agitators 9 and 11 can be driven independently of each other. That is, it may be driven at the same time or only one of them may be driven. Further, each of the agitators 9 and 11 may be movable along the unidirectional W2 of the fermenter 1.

To this end, a transverse rail 25 is provided on the upper surface of the main moving table 7 in a direction perpendicular to the movable rail 3, an auxiliary moving table 27 is seated on the transverse rail 25, And is provided so as to be movable along the extending direction of the rail 25. Further, the agitators 9 and 11 may be provided on the auxiliary moving table 27 to be movable along the unidirection W2 of the fermenter 1, that is, in the left-right direction. Therefore, the agitators 9 and 11 move to the left and right so that they can be transferred to the other side of the fermentation tank 1 even if the object P is supplied anywhere in the fermentation tank 1.

With the above arrangement, the stirrers 9 and 11 pierce the object to be processed, which is supplied to one side of the fermenter 1, with the conveyors 17 and 17 ' . Since the two conveyors 17 and 17 'of the agitators 9 and 11 start simultaneously, the area of the empty space can be doubled by transporting the article P to be processed. The object to be treated 29 can continuously supply the object to be processed to the expanded space K (see FIG. 3) during the time when the stirrer 9 or 11 reciprocates to the other side of the fermenter 1. That is, the object to be processed 29 can be continuously operated without stopping.

A discharging means for sending the object P transferred to the subsequent step to the other side of the fermentation tank 1 is provided. The conventional discharge means may be the discharge hole 31 provided at the bottom of the fermentation tank. The object P falls into the discharge hole 31 and exits the fermenter 1. [ Hereinafter, the object to be processed 29 will be described.

The object to be treated 29 is a series of devices for administering the object P to one side of the fermentation tank 1.

Hereinafter, the object to be processed 29 is mainly described with reference to FIG. The object to be treated 29 includes a storage tank 33 for storing the object P and a supply device for supplying the object P to be stored therein to the fermentation tank. According to the present invention, the object to be treated is supplied by the cyclone principle, and the transfer line (35) blocked with the outside air is required for this purpose. The transfer line 35 is connected at one end to the reservoir 33 and at the other end to the upper side of the fermenter 1.

The rotary pump 37 is installed on the transfer line 35 and press-feeds the object P contained in the storage tank 33. The transfer line 35 can not consist of one straight line and inevitably includes a bent portion B. The distribution adjustment means is for distributing and supplying the object P supplied to the transfer line 35 to several places inside the fermentation tank 1.

The transfer line 35 has a horizontal pipe 39 provided transversely to one side of the upper end of the fermentation tank 1 and a plurality of discharge pipes 34 extending diagonally toward the opening of the fermentation tank 1 41 and may include a vertical tube 43 connecting the storage tank 33 and the lateral tube 39.

A plurality of first valve mechanisms (45) are provided in the transverse pipe. The first valve mechanism 45 is provided so as to be able to open and close the channel of the lateral pipe 39 in a state where it is located behind the position where the discharge pipe 41 is installed. In addition, a second valve mechanism (47) is provided for each discharge pipe (41) so as to open and close the pipe of the discharge pipe (41).

The first and second valve mechanisms 45 and 47 include a valve cylinder 49 operated by hydraulic pressure or air pressure and a valve plate 51 connected to the valve cylinder 49 to open and close the conduit while being operated. The valve plate 51 is actuated across the conduit like a gate valve and a valve plate guide (not shown) is connected to the lateral pipe 39 and the discharge pipe 41 to guide the start of the valve plate 51 .

Particularly, the first valve mechanism 45 is installed at an angle of 45 degrees with respect to the channel. This is to make it easier for the to-be-processed object P to strike against the valve plate 51 of the first valve mechanism 45 flowing into the lateral pipe 39 and then to change direction to escape to the discharge pipe 41. As shown, when the 1-1 valve plate 45-1 of the first valve mechanism 45 is opened and the 2-1 valve plate 47-2 of the second valve mechanism 47 is closed, The object P is struck by the first-second valve plate 45-2 of the first valve mechanism 45 and the direction is switched. When the 2-2 valve plate 47-2 of the second valve mechanism 47 is opened as shown in the figure, the object P is sprayed downward through the second discharge pipe 41. [ In this way, it is possible to determine through which discharge pipe (s) 41 the object P to be discharged is to be discharged.

The agitators 9 and 11 and the first and second valve mechanisms 45 and 47 may be operated in conjunction with each other for automation. The object P to be processed may be ejected simultaneously through the plurality of discharge tubes 41 without necessarily being discharged through only one discharge tube.

According to another embodiment of the present invention, an expansion tube 53 opened in the direction toward the fermentation tank 1 is connected to the lower end of the discharge tube 41. The expansion pipe 53 is formed of a perforated pipe so as to lower the pressure at the end of the discharge pipe 41 so that the to-be-processed product P can be dropped at a low speed, that is, quietly into the fermentation tank 1 without being strongly jetted.

Another embodiment of the present invention is directed to the transfer line 35. Hereinafter, description will be made mainly with reference to Figs. 4 to 6. Fig.

According to the present embodiment, the transfer line 35 includes: a first rectangular pipe 35a having a rectangular cross section; A second tubular section 35b having a square cross section connected to the first tubular section 35a at an angle of 45 to 135 ° and a tubular body section 55 provided at a connecting section between the first and second tubular sections 35a and 35b, .

This embodiment is for coping with the impact applied to the bent portion B (see Fig. 3) of the transfer line by the object P to be processed. Even if the object P is weak in hardness, the impacted portion is worn or damaged when a continuous impact is applied. In this embodiment, the protective cover 57 is provided on the bent portion B where a large impact is applied.

In order to facilitate the replacement of the protective cover 57, the transfer line 35 is formed of a tubular body having a rectangular cross section as mentioned above. The flange 59 is attached to the bent portion B at an angle of 45 to 135 degrees with respect to the channel and more preferably at an angle of 45 degrees so that the protective cover 57 is installed through the flange 59 have.

Meanwhile, the flange 59 may be installed in the process of constructing the first and second pipes 35a and 35b, but the construction may be made more convenient by interposing the connection pipe body 55 formed beforehand between the flanges 59.

The connection pipe body 55 includes a first connection pipe 61 and a second connection pipe 63 which are connected to the first pipe 35a and the second pipe 35b at right angles. Each of these connecting portions can be provided with flanges as shown. However, it is a matter of course that the welding can be performed in addition to the connection method by the flange.

The back portion of the inflection point of the first connection pipe 61 and the second connection pipe 63 is opened at an inclination (b) of 30 to 60 degrees with respect to the pipeline. A flange 59 is provided at the edge of the opening. A protective cover 57 provided with a bolt fitting hole 65 at the edge is coupled to the flange 59 so as to have an inclination of 30 to 60 degrees with respect to the channel of the first angle pipe 35a.

Since the protective cover 57 has a life span, it should be replaced periodically. The replacement period will be determined depending on whether the material is any. Since the protective cover 57 is made of a flat plate material in a simple form, it is not difficult to manufacture and the replacement work is very easy.

The structure of the transfer line having the protective cover 57 (that is, the structure in which the protective cover is inclinedly provided on the back portion of the bent portion using each tube) can be used in addition to the fermentation apparatus of the organic object to be processed of the present invention. The present invention can be applied to a transfer line of various particulate matter transfer devices for transferring, for example, sand, wood powder, grain and the like.

In some cases, the edge of the protective cover 57 which is joined to the flange is made of a flat plate material, and an intermediate portion which is to be collided with the conveyed object may be hemispherical in order to attenuate the impact.

The configuration shown and described above is merely a preferred embodiment based on the technical idea of the present invention. It will be understood by those skilled in the art that various changes and modifications may be made without departing from the scope of the present invention.
