Description

TECHNICAL FIELD [0001] The present invention relates to a food garbage disposal apparatus for producing a solid material having a low water content,

The present invention relates to a food garbage disposal apparatus for producing a solid having a low water content. More particularly, the present invention relates to a food garbage disposal apparatus for mixing a water and a microorganism together in a stirring tank provided with a stirring apparatus, The present invention relates to a food waste disposal apparatus for producing a solid material having a low water content for sufficiently separating a liquid material and a solid material from each other and discharging pure liquid material to sewage.

Among the various methods for treating food waste generated in homes and restaurants, the liquid phase extinction method can prevent the decay by shortening the processing time and can utilize the heat generated in the decomposition process of the organic matters of the microorganisms, And the microorganisms contained in the effluent water have a favorable effect on the quality of sewage water. An example of the apparatus for dissolving a liquid phase is an apparatus disclosed in Japanese Patent Registration No. 10-1131935. The disclosed apparatus includes a stirring shaft 20 provided with a stirring blade 21 provided in a stirring tank 10 and the stirring shaft 20 is rotated in the stirring tank 10 by a driving motor 40 provided on a side surface . A lower tread 141 is provided on the lower side of the stirring tank 10 so that the liquid containing the inorganic material falling down to the lower portion of the stirring tank 10 is filtered and discharged by the discharge guide 14. [ A nozzle 12 for spraying hot water is formed in an upper portion of the stirring tank 10. On the other hand, the oxygen supplying means 70 provided in the stirring tank 10 continuously supplies oxygen required for decomposing and culturing microorganisms.

As described above, in the conventional art, the liquid decomposition product produced in the fermentation and stirring process of the microorganism in the agitating tank 10 is firstly filtered by the lower tread 141, and then is introduced into the sewage as it is. However, in the decomposition tank 10, the liquid-phase decomposed primary filtrate through the lower tread 141 includes sludge which is not completely decomposed and becomes a source of sewage when it is directly discharged into sewage. According to Article 10 (3) of the Enforcement Regulations of the Waste Management Act, the compliance standards for solids outflow are strengthened, limiting the outflow rate of solids outside the waste treatment facility. That is, in the case of food wastes from small processing facilities of 100 kg or less, the weight of solids discharged together with the effluent after the processing of the facility is limited to 20/100 of the weight of the solids to be introduced. Therefore, the liquid processing apparatus as described above can not satisfy the revised laws and regulations, and the use thereof is restricted.

Patent No. 10-0959901 provides a food waste disposal apparatus including a sludge circulation unit for achieving complete decomposition by recycling primary filtered primary sludge (solids) into a decomposition tank and circulating it. However, in the case of the latter technique, the pumping means 42 is driven to circulate the sludge forcibly. In addition, there is a problem that the working environment is deteriorated due to the generation of bad odor in the stirring tank due to the sludge flowing backward in the forced circulation process, There is a problem of causing the device to malfunction. The stirring tank can not be kept in a completely sealed state with the outside because the food waste is periodically opened by opening the inlet of the food waste. Therefore, there is a need for a new technology capable of fundamentally preventing the generation of odor in the stirring tank together with the complete decomposition of the sludge, and at the same time, it is possible to provide only the separated liquid material with the solid content.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic diagram of a food waste disposal apparatus developed before a food waste disposal apparatus for producing a solid having a low water content according to an embodiment of the present invention. Referring to FIG. 1, the food waste disposal apparatus of the present invention includes a stirring tank 100, a crushed water storage tank 200, a first solids separation tank 300, and a first solids conveyance device 400, do.

The stirring tank 100 is provided with a stirring device 110, and the charged foodstuff, the supplied microorganisms and water are stirred and mixed by the stirring device 110 to produce a liquid crushed product. The stirring tank 100 is provided with an inlet through which food waste can be injected so that the inlet 101 is manually or automatically opened by gravity or injection equipment so that the food waste is injected into the stirring tank 100 . The stirrer 110 is installed in the stirring tank 100 and is configured to mix the food waste with water and microorganisms separately supplied. The stirring wing 111 of the stirrer 110 allows the food waste to have a small size Mixed while being pulverized. By the operation of the repetitive stirring device 110 for a sufficient time and by the decomposing action of the microorganisms, the food waste in the form of the first lump is changed into liquid crushed material.

A water supply nozzle 102 is formed at an upper end of the stirring tank 100 to continuously or intermittently supply water for liquefaction of food waste. The water tank 104 is provided at the lower end of the stirring tank 100 so that the water in the water bottle 104 is drawn up through the pipe 121 and water is sprayed into the stirring tank 100 through the water supply nozzle 102 . It is preferable that the water sprayed into the stirring tank 100 is heated using warm water heated to a temperature corresponding to the growth conditions of the microorganisms. The water supply nozzle 102 can be configured to be sprayed with a strong enough pressure to clean the components constituting the stirring device 110 in the stirring tank 100 in the stirring process. Therefore, it is important to arrange the spraying direction of the water supply nozzle 102 toward the portion where the washing tank 100 needs to be continuously washed.

In addition, at the lower end of the stirring tank 100, a warming device 106 including a hot wire is provided so as to surround the stirring tank 100, thereby providing a temperature condition in which microorganisms can be optimally grown. The microorganisms once injected into the stirring tank 100 are completely stopped for the movement and maintenance of the apparatus, and during the operation of the equipment, the food waste is continuously injected during the operation of the equipment, (100).

The pulverized material storage tank 200 is formed with a filtration plate 120 formed at the lower end of the stirring tank 100 as a boundary so as to filter and store the pulverized liquid material generated in the stirring tank 100. A filtration plate 120 is provided at a boundary portion where the agitation tank 100 and the pulverized material storage tank 200 are in contact with each other so that the liquid material generated in the agitation tank 100 is supplied to the pulverized material storage tank 200 ) And stored. The bottom surface of the lower end of the pulverized-material storage tank 200 is formed to be inclined to one side, and the discharge port 204 is formed to the lower side. The pulverized liquid accumulated in the pulverized-material storage tank 200 is not composed of a completely liquid material, but a fine-sized solid material which is not fully liquefied in the stirring tank 100 is mixed. The solid material is accumulated on one side of the bottom surface of the pulverized material storage tank 200 and is easily discharged together with the liquid material through the discharge port 204. The solid material accumulated at the lower end of the pulverized material storage tank 200 is a material whose specific gravity is larger than that of the liquid material because the material having a specific gravity lower than that of the liquid material in the solid material can not be precipitated in the pulverized material storage tank 200.

The first solids separation tank 300 receives the liquid pulverized material from the pulverized material storage tank 200 and separates the solid matter in the liquid pulverized material by sedimentation. That is, the present invention is configured such that only the liquid material in which the solid matter is separated is discharged to the sewage. The pulverized liquid material transferred through the discharge port 204 of the pulverized material storage tank 200 is mainly mixed with the solid material and the liquid material.

The maintenance lid 320 may be installed at the upper end of the first solids separation tank 300. However, it is preferable to completely close the maintenance lid 320 to prevent the leakage of odor during operation of the apparatus. The transfer of the pulverized material from the pulverizing material storage tank 200 to the first solids separation tank 300 can be carried out continuously or at regular time intervals. When a certain amount of the pulverized material transferred to the first solids separation tank 300 is supplied with the new pulverized material from the pulverized material storage tank 200 during the precipitation in the separation tank 300, And the backflow of the fluid occurs, so that the separation of the solids may not be effective. Therefore, after the solids transferred to the first solids separation tank 300 are all separated and the liquid material is discharged to the sewage, freshly pulverized material is transferred again from the pulverized material storage tank 200 to be separated .

The source for conveying the pulverized material of the pulverized material storage tank 200 to the first solids separation tank 300 may be arranged by arrangement or by an intermediate transfer device. It is sufficient to form the inlet of the first solids separation tank 300 at a position lower than the bottom surface of the pulverized water storage tank. In this case, an opening / closing valve may be provided in a connection pipe connecting the crushed water storage tank 200 and the first solids separation tank 300 to control the transfer of the crushed material. In the latter case, the conveying pump 700 is provided to transfer the pulverized liquid stored in the pulverized material storage tank 200 to the first solids separation tank 300 as an example . At this time, the conveyance of the pulverized material will be controlled by the operation of the transfer pump 700. The inflow pipe 710 of the transfer pump 700 is connected to the discharge port 204 of the pulverized water storage tank 200 and the discharge pipe 720 is connected to the inflow port 312 of the solids separation tank 300 . For the preferred practice of the present invention, unnecessary up-and-down placement of components would be undesirable, since it is desirable to make the size, especially the height, of the device as small as possible. Therefore, the configuration by the transfer pump 700 will be more practically possible, and it will be effective to constitute all the configurations of the present invention in one case 10. [

The first solids conveying device 400 separates and transfers the solids settled at the lower end of the first solids separation tank 300 from the liquid material. In addition, the present invention may further include a solids storage box 800 for finally collecting the solids transferred by the first solids conveying device 400. The solids collection box 800 can be configured to collect withdrawn solids that are periodically filled with a withdrawable drawer 810 for withdrawing the accumulated solids therein, for example, in a drawer fashion, It could be recycled. On the other hand, the liquid material from which the solids are separated through the liquid matter discharge port 314 and the discharge pipe 318 from the first solids separation tank 300 will be discharged to the sewage on the basis of the law.

The first solids separation tank 300 has a crushing water inlet 312 formed at the upper end thereof and a crushing water inlet 312 formed at the upper end of the first solids separation tank 300.

The solids conveyance pipe 450 includes a first conveyance screw 420 therein and communicates with a solids discharge port 316 at a lower end thereof and an outlet port 430 at an upper end thereof. In addition, the first solids conveying device 400 should be installed to be inclined with respect to the ground. Accordingly, the liquid material in the solid material conveyance pipe 450 does not move due to the appropriate rotation speed of the first conveyance screw 420, and only the solid material is separated while rotating together with the rotation of the first conveyance screw 420, , The first conveyance screw 420 is configured to continuously push the solids upwards and fall to the solids sump 600. On the other hand, a decelerating device may be provided between the driving motor 410 and the first conveying screw 420, for example, by gears or belt connections 442, 444 and 446.

3 is a plan view showing a state in which the loading port is opened, FIG. 3 (b) is a plan view showing a state in which the loading port is sealed, and FIG. 4 is a cross- 4 is a perspective view showing a specific configuration of the input port opening and closing member 460 of FIG. 3 and 4, the first solids conveying device is also formed with a charging port opening / closing member 460 for intermittently charging the solid material to be introduced through the charging port 455.

The screw rotating shaft 422 may be received through the screw receiving port 466 and may be fixed to the screw rotating shaft 422 on the opposite side of the screw receiving port 466. In addition, a part of the first conveying screw 420 formed on the outer periphery of the screw rotating shaft 422 may be configured to be contained inside the loading port opening / closing member 460.

The solid material in the first solids separation tank 300 can be separated from the solid material in the first solids separation tank 300 by the charging holes 464 of the charging port opening / closing member 460 that is intermittently opened and closed with respect to the charging port 455 formed at the lower end of the solid matter conveyance pipe 450. [ Can be intermittently conveyed through the first solids conveying device (400). In this configuration, since the substance to be transferred from the first solids separation tank 300 to the first solids conveyance device 400 is conveyed not only solids but also liquid matter, the pulverized product stored in the first solids separation tank 300 The solid matter may flow into the solid material conveying apparatus 400 for a short period of time together with the liquid material to rise. In order to solve such a problem, the first solids conveying device connected to the lower end of the first solids separation tank 300 is a kind of intermittent device which is configured to rotate with respect to the charging port 455, 464, which are provided in the inlet opening / closing member 460. 3 (a) is a state in which the charging hole 464 coincides with the charging port 455, and FIG. 3 (b) is a state in which the charging port opening / closing member 460 is rotated with respect to the charging port 455, State. 2 (b) to 2 (e) show the overall appearance b for showing the major components in the first solids conveyance device 400, the state c in which the solids conveyance pipe 450 is removed, A lower end supporting portion 470 for receiving the lower end 428 of the first conveying screw 420, a gear 442 and the like for receiving the lower end 428 of the first conveying screw 420 And a loading opening and closing member 460 fixed to the screw rotating shaft 422 is also shown and FIG 2E shows a state in which the loading hole 464 of the loading opening and closing member 460 is seen.
