Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention recovers raw garbage, garbage, and dead meat or filth from various meat factories, which are organic wastes, and converts the raw materials into a form that can be used as feed or fertilizer. The present invention relates to an organic waste recycling vehicle for recycling.

[0002]

2. Description of the Related Art In recent years, it has been widely seen that organic waste such as garbage, garbage, carcasses or filth discharged from various meat factories is dehydrated and powdered to be recycled as feed or fertilizer. It is becoming. This is because it is more economical to recycle and use organic waste than to dispose of it.In addition, the fact that components such as proteins contained in organic waste are suitable for feed and fertilizers Because it was re-recognized. In such a regeneration treatment, it is necessary to appropriately dehydrate and deoil the organic waste as a raw material, and in the old days, oil temperature dehydration treatment is known, but in addition to this, in a stirring mixer (called a cooker or a dryer). A method in which a raw material is fried with a small amount of oil (commonly referred to as “fried method”) is used (Japanese Patent Application Laid-Open Nos. 7-35477 and 7-47254). Usually, each factory, hotel, restaurant, and the like are provided with a reprocessing facility using the above method, and individually treat garbage and garbage.

[0003]

[0007] Even in the case of recycling organic waste, in reality, each factory, hotel, and restaurant must be provided with a dedicated recycling processing facility. In practice, many factories, At present, hotels do not have reprocessing facilities. This is because most of the general-purpose reprocessing equipment is large, and the initial investment is high, and the operation and maintenance costs are higher than the amount of garbage and garbage that is discharged daily from small factories and hotels. Therefore, it is not easily spread. For example, taking the above-mentioned “stir-fry method” as an example, in order to treat garbage regardless of the type of raw garbage,
Mixer for crushing raw materials, hopper that also has function of adjusting oil content of raw materials, stirring mixer for dehydrating raw materials, condenser for cooling water vapor containing oil output from stirring mixer, filtration for separating water and oil components Equipment is required,
Even if each part was made smaller, there was a limit, so the entire equipment had to be enlarged.

[0004] To promote the recycling of organic waste,
It is preferable that equipment be installed in more factories, hotels, and the like, but this is practically difficult as described above. In that case, a method is also conceivable in which a recycling facility is provided at a specific location, and garbage, trash, and the like discharged from various locations are collected in the recycling facility and processed collectively. However, according to this method, the feed or fertilizer produced after the regeneration treatment cannot be used unless it is transported again, and the transportation cost such as raw material collection and product delivery is increased.

[0005] Therefore, in order to realize the recycling of organic waste such as garbage and garbage discharged from relatively small factories and hotels where it is not possible to provide a dedicated recycling facility, collection of organic waste is performed. In order to realize self-propelled reprocessing equipment that can take charge of reprocessing and product delivery,
Based on the "stir-fry method", we studied to reduce the size of each part for mounting on a vehicle and to devise the connection or arrangement of each part.

[0006]

SUMMARY OF THE INVENTION As a result of the study, what has been developed is a vehicle equipped with a reprocessing device for dehydrating a raw material such as organic matter or organic waste, wherein the regenerating device has an oil content of the input raw material. A raw material hopper for pulverizing or kneading while adjusting, a transfer path for receiving and sending the raw material from the raw material hopper, and confining the raw material received from the transfer path in a closed path having a heating means or a heat retaining means and transferring the raw material in one direction. A stirrer-mixer for dewatering the raw material while agitating or pulverizing the raw material by flipping it up in a direction substantially perpendicular to the transfer direction, and a gas processing unit for processing steam and waste gas discharged from the raw material hopper or the stirrer-mixer. Organic waste recycling vehicle (hereinafter abbreviated as a processing vehicle). In the hopper, the raw material may be preheated to perform a pretreatment for removing water.

The transfer section is a feed screw for transferring the raw material while compressing it. The screw gradually narrows the pitch in a path from the screw inlet to the screw outlet, and the screw is omitted near the screw outlet. A cutter is attached, and an orifice-shaped perforated plate that extrudes the compressed raw material into an elongated shape is disposed at the screw outlet. In addition, the stirring mixer has a long processing path formed by connecting a plurality of closed paths of a predetermined length, and each closed path has an ascending gradient from the inlet of the stirrer to the outlet of the stirrer.

The gas processing section (1) is a boiler that burns water vapor and waste gas to generate a combustion gas. The boiler discharges the combustion gas into the atmosphere, and also uses a part of the combustion gas as a raw material hopper or an agitated mixer. (2) an ejector that cools and liquefies steam and waste gas introduced into a closed water tank under negative pressure by the gas processing unit, and uses the steam and waste gas to the bottom of the water. It is preferable that the water vapor is liquefied in the process of discharging and rising toward the water surface around the bypass wall in the water tank to remove foreign matter from waste gas.

The processing vehicle according to the present invention has a reduced number of devices constituting all the processing steps and a sufficient regeneration processing facility in the installation space on the vehicle, as compared with the conventional ground-based regeneration processing equipment. There is a feature. First, a conventional hopper for storing a raw material and a mixer for adjusting the oil content of the raw material are realized only by the hopper of the present invention. In the transfer path, in order to efficiently carry out the dehydration treatment in the post-process, the raw material whose oil content has been adjusted is squeezed by a screw with a narrow pitch, finely divided by a cutter and an orifice plate, and sent out to a stirring mixer. In order to obtain a long processing path, the stirring and mixing machine forms a long processing path by connecting a plurality of closed paths of a fixed length having an ascending gradient from the stirrer inlet to the stirrer outlet. When the closed paths intersect, the outlet of the former-stage agitator and the inlet of the latter-stage agitator can be connected in the shortest direction in a substantially vertical direction.

[0010] The gas treatment section composed of an ejector removes foreign substances by using water in a water tank as a filter while liquefying steam or waste gas. Compared with a conventional wastewater treatment apparatus, a condenser for liquefaction is omitted. This contributes to a reduction in the number of devices. The closed water tank under negative pressure deprives steam and waste gas of heat and liquefies due to the low temperature environment due to negative pressure and the large heat capacity of a large amount of water in the water tank. As a result, the foreign matter comes to the surface of the water or settles on the bottom of the water. By providing a drain port at the end of the bypass wall provided in the water tank, the foreign matter is left in the water tank and only the water is taken out of the water tank. be able to.

[0011] A gas processing section comprising a boiler supplies a combustion gas as a heating medium necessary for a stirring mixer (dehydration processing) or a hopper (preliminary processing), and also supplies steam and waste discharged from the stirring mixer or hopper. It is a device that burns gas with the combustion gas and combines a heat source and a waste gas treatment facility that have been conventionally separated. The combustion gases are introduced into the space of the heat insulating jacket or directly into the stirring mixer or hopper, for example as a substitute for a stirring mixer or steam for heating the hopper.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described.
This will be described with reference to the drawings. FIG. 1 is a perspective view showing an example of a loading form of each part in the processing vehicle 1 of the present invention.
3 is a configuration diagram of each section mainly showing a flow of processing of a raw material. As shown in FIG. 1, the processing vehicle 1 of the present invention includes a raw material hopper 3 on a loading platform 2, a feed screw 4 serving as a transfer path, and a stirring mixer 6 including four closed paths 5, 5, 5, 5. A boiler 8 that supplies hot air as a heating medium to the gas processing unit 7, the raw material hopper 3 and the stirring and mixing machine 6 is loaded, and raw garbage and kitchen garbage, etc., which become raw materials, are collected around a city or the like like a garbage truck. The reproduction process is performed during traveling or at a predetermined point.

The raw material hopper 3 is, as shown in FIG.
A double-structured ribbon screw 12 is provided in a container 11 having a hopper inlet 9 and a hopper outlet 10. A cutting blade 13 for cutting the raw material is attached to the ribbon screw 12, so that the input raw material can be roughly crushed and kneaded. Further, the hot air supplied from the boiler 8 (see FIG. 1) can evaporate a certain amount or more of water in the raw material, or can adjust the oil content in the raw material by replenishing oil or water as needed. . The evaporated water is supplied to the gas treatment unit 7
(See FIG. 1).

The feed screw 4 incorporates a screw shaft 17 having a uniform pitch in the first half and a gradually narrowing pitch in the feed direction of the raw material in the second half in a cylinder 16 having a screw inlet 14 and a screw outlet 15. I have. Raw material is screw shaft
It is sent while being squeezed by 17, cut into a certain length by a cutter 18 arranged near the screw outlet 15, and further separated into pellets from an orifice plate 19 (FIG. 3: AA sectional view in FIG. 2) and discharged. Is done. Thus, by adjusting the oil content and kneading the raw material into pellets,
The dewatering process in the stirring mixer 6 (see FIG. 1) can be performed efficiently.

FIG. 4 is a sectional view in the feed direction of the raw material showing the structure of the closed passage 5 constituting the stirring mixer 6 of the present embodiment, and FIG.
It is middle BB sectional drawing. As shown in FIG. 4, the stirring mixer 6 is provided with a throw block 22 in a substantially oval cross section (see FIG. 5) having a stirrer inlet 20 and a stirrer outlet 21.
A stirrer shaft 24 having discs 23 provided at equal intervals and having a built-in structure is eccentrically mounted downward, and the material is transferred while being dehydrated by a "stir-fry" process using hot air. FIG.
The middle and solid arrows indicate hot air, the broken arrows indicate water vapor and waste gas evaporating, and the thick arrows indicate the direction of material transfer.

As can be seen in FIGS. 4 and 5, three throwing blocks 22 are attached to the outer periphery of a disk 23 integrated with a stirring shaft 24 at intervals of 120 degrees, and the raw materials are respectively supplied to the outlet of the stirrer. An inclined surface 25 for extruding the raw material toward 21 and a throwing surface 26 for jumping up the raw material in a direction perpendicular to the feed direction of the raw material are provided. Further, a cutting blade 27 for cutting the raw material over the inclined surface 25 and the throwing surface 26 is provided. The throw block 22 rotates together with the stirring shaft 24, and pushes the raw material confined in the closed passage 5 in one direction while pushing the raw material on the inclined surface 25, and bounces the raw material toward the inner wall surface of the closed passage 5. Then, the raw material is stirred while being cut by the cutting blade 27. The raw material is dehydrated by hot air while undergoing the stirring movement. A crushing blade 28 is attached to the inner wall surface of the closed path 5 corresponding to the raw material throwing direction as a raw material scattering means. The scattering means may be a rotating body having an axis in the feed direction of the raw material.

The stirring and mixing machine 6 of this embodiment is provided with four closed paths 5, 5, 5, 5 having an ascending gradient in the direction in which the raw materials are transferred, to secure the path length required for the dehydration treatment. In addition, since each closed path 5 has an ascending slope, the raw material pushed on the inclined surface 25 of the throwing block 22 is divided into one that moves in the transfer direction and one that is returned in the reverse direction. The vehicle will travel in route 5. Thereby, in the stirring mixer 6 of the present example, the raw material is transferred over a relatively long time as compared with the total length of each closed path 5, and a sufficient dehydration treatment can be performed. For this reason, for example, of the four closed paths 5, 5, 5, 5, the dehydration process is performed in the first three paths, and in the last closed path 5, the raw material is not heated, but is cooled while being released by stirring. Processing can also be performed.
Further, when the closed path 5 is inclined as in this example, it is useful to reduce the installation area of the apparatus. In addition, in order to reduce the installation area, a stirring mixer having a loop-type closed path for circulating the raw material may be used.

The heat for dehydrating the raw material can be applied not only by blowing the hot air directly into the closed passage 5 but also by various means. For example, as shown in FIG. 6 (corresponding to FIG. 4), the outer wall surface of the closed passage 5 is covered with a heat insulating jacket 30 having a gap 29, and high-temperature steam is circulated through the gap 29 to close the closed passage 5. In addition to the means for heating 5 itself, heating means using electromagnetic waves can be used.

FIG. 7 is a cross-sectional view of the gas processing section 7 including the ejector 32, and FIG. 8 is a partial cross-sectional view of the gas processing section 7 serving also as the boiler 8. Due to the extremely small installation area of the loading bed 2, a gas processing unit composed of a plurality of devices such as ground-based equipment cannot be used. Therefore, the present invention basically treats steam and waste gas with a single device configuration. I do. Moreover, the gas processing unit 7 serving also as the boiler 8 can burn the steam and the waste gas to incinerate the foreign matter and supply the combustion gas to the raw material hopper 3 or the stirring mixer 6 as a heating medium. There is an advantage that the installation space can be reduced.

The gas processing section 7 composed of the ejector 32
As can be seen in FIG. 7, pump into closed water tank 33 under negative pressure.
An ejector 32 driven by 40 discharges water vapor and waste gas toward the bottom of the water, liquefies in a process of passing through a bypass 34 in a closed water tank 33 maintained at a low temperature by negative pressure, and filters the bypass 34 for foreign matter. And only the liquefied steam is drained. The negative pressure of the closed water tank 33 is controlled by a sub-ejector 35 driven by a pump 41 attached to the side.
It is realized by sucking the air inside. Conventionally, when liquefying water vapor and waste gas, a condenser for cooling is used in addition to a liquefaction device including an ejector, whereas in the present invention, cooling and liquefaction are performed only in a closed water tank 33 using an ejector 32. They are different. This small gas processing unit 7 greatly contributes to the realization of the processing vehicle of the present invention.

The gas processing unit 7 also serving as the boiler 8 is provided in FIG.
As can be seen from the above, when generating a combustion gas as a heating medium to be supplied to the raw material hopper 3 or the stirring mixer 6, the steam or the waste gas is burned to incinerate and remove foreign matter. The steam and the waste gas are forcibly sent to the lowermost layer of the boiler 8 by the fan 42, remove large foreign substances through the first filter 36, incinerate by the burner 38 in the combustion chamber 37, and further pass through the second filter 39 to the combustion gas. Is forcibly sent to the raw material hopper 3 or the stirring mixer 6 by the fan 43, and the rest is exhausted to the atmosphere. Since the gas processing unit 7 also serves as the boiler 8, it can further contribute to a reduction in installation space.

[0022]

According to the treatment vehicle of the present invention, organic wastes such as garbage and garbage discharged from relatively small factories and hotels, for which a dedicated regeneration treatment facility cannot be separately provided, are collected and easily recycled. Processing can be performed. Recycled raw materials can be used as fertilizer and feed, and the processing vehicle also functions as a transportation means, so that costs can be reduced. In the future, garbage from general households will be collected by the treatment vehicle of the present invention, and not only will it be collected and incinerated or landfilled as it is now, but it will also be useful to perform recycling while collecting it. By reusing it as a valuable resource, it will also be possible to contribute to reducing collection costs.
