Description

Technical Field [0001] The present invention relates to an automatic discharge device for food waste, and a food waste collection container having the device,

The present invention relates to a device for automatically discharging food waste, and a cleaning device for a garbage collecting container having such a device. More particularly, the present invention relates to a device for automatically discharging garbage mixed with food wastewater container washing water, To a container cleaning vehicle.

The disposal of organic wastes, ie food waste, is carried out in various forms in accordance with the environmental policies of the national or local organizations. Whether or not the local wastes are farming and fishing villages or urban areas, Various methods of processing which are considered to be more suitable are being tried. Also, depending on whether the residential area is a residential type for each household, that is, whether it is an apartment, a villa or a tenement house, a small-sized housing complex located in a residential area divided into several houses, or a single- The treatment method is different. On the other hand, in the case of a commercial area, there are also various considerations depending on whether or not the area is a dense eating area where a large amount of food waste is discharged every day.

At present, the Republic of Korea is discharging food waste based on the weight-based system in most of the regions, and the automatic collection facilities constructed with urban infrastructure in the newly constructed new city area and the RFID-based electronic weighing The proportion of food garbage disposal devices is increasing. However, there is still a lot of food waste disposal methods, such as discharging food waste contained in a special bag, that is, food waste, into a collecting container for public use or private use, or sometimes discharging the food waste directly to a collection container without using a baggage bag. In particular, in the case of a restaurant or the like where a large amount of food waste is discharged, it is preferred that the food waste is directly discharged to the collection container and the food waste collection vehicle collects the food waste.

In the garbage collection container, it is often the case that the dedicated collection container is washed and used in each home or workplace where the collection container is used. However, in the case of the public collection box or some dedicated collection containers, The container is cleaned and sterilized to prepare for the next use. A cleaning vehicle equipped with such a collection container cleaning apparatus is disclosed in Japanese Patent Application No. 10-0820326 and Registration Utility Model No. 20-0419057.

When the collection container is washed, the food waste remaining in the collection container is mixed with the washing water and discharged as sewage. Conventional washing vehicles send the same to the sewage tank or to the outside. This may cause damage to the sewage transport pump that clogs the filter in the pipeline leading to the sewage tank and sucks the sewage into the sewage tank, and may also cause pollution of the surrounding environment when discharged to the outside. In addition, when the washing water is exhausted, the washing vehicle must be moved to return the washing water to the washing machine, and then the washing water must be returned to the workpiece to continue the collection container washing operation. In order to remedy such inefficiency, However, when food waste is mixed with sewage, it is difficult to recycle such waste water.

In view of this point, Japanese Patent No. 10-1471372 provides a garbage container cleaning car equipped with a screen for filtering food waste falling down inside a collection container being cleaned. In addition to the screen, there is also provided an air ejection tube for ejecting high pressure air to the screen so as to prevent food waste from accumulating and blocking the screen, thereby separating the food waste from the screen.

However, when the above-mentioned air spraying pipe is unable to smoothly pass the screen through the screen due to the food waste accumulated on the screen, the mass of the food waste sandwiched between the screens is widely spread by the high-pressure air, To form a wash water passage on the screen, and does not remove accumulated food waste. Therefore, at some point, the cleaning chamber is opened or disassembled, and the food waste accumulated on the screen is manually removed and discharged to the outside.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an apparatus for automatically discharging food waste according to the present invention will be described in detail with reference to the accompanying drawings, and a garbage container cleaning vehicle having the apparatus.

1 is a plan view schematically showing a garbage container cleaning vehicle according to the present invention, and Fig. 2 is a front view.

The food garbage collection container cleaning vehicle typically includes a cleaning device 20 for cleaning the collection container, a cleaning chamber 10 where the cleaning device 20 is installed to perform the collection container cleaning, And a waste water tank 70 for storing the wastewater after cleaning. The food waste remained after being attached to the collection container is separated and separated from the collection container by the cleaning, mixed with the cleaning water used for cleaning, and discharged into the washing chamber bottom surface 40, forming a waste water. The wastewater discharged to the washing chamber bottom surface 40 flows into the wastewater temporary storage 30 and is sucked up by the wastewater transfer pump 50 through the wastewater suction pipe 55 and transferred to the wastewater tank 70 And Fig. 4). Therefore, if food wastes are contained in the wastewater conveyed to the wastewater tank 70, it may cause problems such as clogging of the wastewater suction pipe 55, damage to the waste water transfer pump, and the like. Even if a filter is provided at the inlet of the waste water temporary storage 30 or the inlet of the waste water suction pipe 55 in the transfer path of the wastewater by recognizing such a problem, food wastes accumulate in the filter, It may be troublesome to clean the filter frequently.

The food waste dehydrator 900 according to the present invention is installed in the vicinity of the washing chamber bottom surface 40 to automatically discharge the food waste contained in the waste water falling or flowing down to the washing chamber bottom surface 40, Can be solved.

Hereinafter, an apparatus for automatically discharging food waste according to the present invention will be described in detail with reference to FIGS. 3 to 5. FIG.

3 is a view showing an embodiment of an apparatus for automatically discharging food waste according to the present invention as viewed from the rear of a garbage collection container cleaning vehicle, and FIG. 4 is a view showing an embodiment of the automatic discharge device as viewed from the side of the cleaning vehicle And FIG. 5 is a view showing the driving part and the chain tensioner part of FIG. 3 as viewed from above.

The automatic waste food waste ejection apparatus 900 according to the present invention includes a first conveyance unit 110, a scraper 310, a second conveyance unit 120, a first guide surface 410, a third conveyance unit 130, A surface 420, a driving unit 510, and a debris removal unit 620.

Although the essential components of the present invention are clearly defined and divided into separate components for the convenience of description, the first to third transfer units 110, 120, and 130 may include one continuous transfer unit 100 as a whole, And is moved by the driving unit 510 in advance.

The scraper 310 is continuously moved along the bottom surface 40 of the cleaning chamber 40, the first guide surface 410 and the second guide surface 420 by the continuous conveying means 100. [ So that the food waste discharged to the washing chamber bottom surface 40 is transferred to the residue receiving unit 620.

Hereinafter, each component of the food waste remover 900 according to the present invention will be described in detail.

The first transfer part 110 is formed of a pair of mutually parallel and arranged parallel to the bottom surface 40 of the cleaning chamber 40, that is, substantially parallel to the bottom surface 40 of the cleaning chamber 40, And is spaced apart by a predetermined height (H). The first transfer unit 110 may be configured to move from the first direction switching unit 210 to the second direction switching unit 220 in the first direction 710.

In the illustrated embodiment, the sideways first direction 710 is not limited to the direction from left to right as seen from the rear side of the vehicle, but is not limited to this direction, and may be different depending on the vehicle condition or other necessity ≪ / RTI > The first direction 710 may be a horizontal direction. However, when the bottom surface 40 of the washing chamber 40 is inclined due to smooth transfer of wastewater or the like, the direction is not horizontal but parallel to the inclination Will be. This is because the first transfer part 110 is disposed to be parallel to the cleaning chamber bottom surface 40.

The first conveying unit 110 is a power transmitting means for transmitting the power generated by the driving unit 510 and a food waste conveying unit for discharging the food waste discharged to the washing chamber bottom surface 40 to the outside. In the illustrated embodiment, the first conveying unit 110 is formed of a chain, but the present invention is not limited thereto. The conveying unit may be configured as any means capable of simultaneously performing power transmission and food waste conveyance. This also applies to the second to sixth conveyance units 120, 130, 140, 150, and 160, which will be described later.

The first direction switching unit 210 and the second direction switching unit 220 allow the driving force of the driving unit 510 to be transmitted by the first conveying unit 110 and change the moving direction of the first conveying unit 110 It is means. In the illustrated embodiment, the sprockets combined with the chain are used as the first and second direction switching units 210 and 220, but may be a pulley when the first conveying unit 110 is a belt Do not. This is the same for the third to sixth direction switching units 230, 240, 250 and 260 to be described later. Since the first transfer parts 110 are formed as a pair, the first and second sprockets constituting the first and second direction switching parts 210 and 220 are also formed as a pair, The second sprockets are connected to each other by first and second direction switching shafts 213 and 223, respectively. The second to sixth conveyance units 120, 130, 140, 150, and 160 are also formed as a pair as described later. Therefore, in addition to the first and second direction switching units 210 and 220, Third to sixth sprockets constituting the sixth to tenth switching units 230, 240, 250 and 260 are also formed as a pair. Also, the pair of third to sixth sprockets are connected to each other through the third to sixth switching unit shafts 233, 243, 253, and 263, respectively.

One or more scrapers 310 having a predetermined width W are positioned between the pair of first transfer units 110 and the scrapers 310 are moved together with the first transfer unit 110. The scraper 310 is coupled to the first transfer unit 110 so as to extend from the first transfer unit toward the bottom surface 40 of the cleaning chamber by the predetermined height H, This allows the extended end 313 of the scraper 310 to be positioned so as to touch or almost touch the bottom of the cleaning chamber 40 and thus move the food waste discharged to the bottom of the cleaning chamber 40 by pushing. The end portion 313 may be provided on the cleaning chamber bottom surface 40 such as scratching the cleaning chamber bottom surface 40 by providing a minimum clearance between the end portion 313 of the scraper 310 and the cleaning chamber bottom surface 40. [ So that noise can be prevented from being generated. In calculating the minimum allowance, the maximum deflection of the middle portion of the chain should also be taken into account when the first transfer portion 110 is formed of a chain. This minimum clearance configuration is the same between the scraper 310 and each of the first to third guide surfaces 410, 420, and 430 described later, as well as between the scraper 310 and the cleaning chamber bottom surface 40 It is applied part.

In the illustrated embodiment, the scraper 310 is formed in a substantially rectangular shape having the predetermined height H and a predetermined width W, and has a plurality of perforation holes 311. The perforation hole 311 allows the wastewater to pass through the scraper 310 without being pushed by the scraper 310 when the scraper 310 pushes and moves the garbage mixed in the wastewater. Thus, the resistance due to the wastewater which may occur when the wastewater is pushed together with the food waste can be reduced, and the power required for the movement of the scraper 310, that is, the movement of the first conveyance unit 110, can be reduced. In addition, when the sewage is pushed together with the food waste, the water level of the sewage can be temporarily and partially increased, and the sewage flowing out of the gap between the both sides of the relatively low water level sewage can be formed . The flow of the wastewater can be pushed by the scraper 310 to allow the food waste to be discharged to the outside to flow out into the gap on both sides of the scraper 310 and to stay on the bottom 40 of the washing chamber. Thereby hindering the discharge efficiency of the discharge device. The plurality of perforation holes 311 formed in the scraper 310 can solve these problems.

The scraper 310 may be formed by perforating a plurality of perforation holes 311 on the plate material cut in accordance with the predetermined height H and the predetermined width W in advance and the perforation hole 311 may be formed in advance It may be formed by cutting a plate material of a large size. In the latter case, there is an advantage in the punching process because the handling of the base material is usually easy. In the latter case, a cutting line may be formed along a portion where the perforation hole is not formed, or a cutting line may be formed to cross the plurality of perforation holes. When cutting is performed along a portion where the perforation hole is not perforated, the end portion 313 of the scraper 310 will form a smooth straight line. However, when cutting is performed across a plurality of perforation holes, May be unevenly formed by a combination of a straight line and an arc. However, even though the perforation hole 311 is formed in such a size that most food waste does not pass through in the beginning, even if the perforation hole is formed on the end portion 313 in a partially cut circular arc shape, There is no problem in performing the function of the scraper 310 for discharging and discharging it.

The scraper 310 is disposed in a direction perpendicular to the first direction 710 and perpendicular to the first transfer unit 110, that is, in a direction crossing the pair of first transfer units 110 at a shortest distance . In this case, the predetermined width W of the scraper 310 may be set smaller than the distance between the pair of first transfer units 110. Unlike the illustrated embodiment, the scraper 310 may be disposed in a direction diagonally crossing the pair of first transfer units 110. In this case, the predetermined width W of the scraper 310 may be set to be less than, equal to, or greater than the distance between the pair of first transfer units 110 depending on the degree of inclination.

If the number of scrapers 310 is two or more, the scrapers 310 can be continuously disposed at regular intervals, and the interval is determined by the average amount of food waste contained in the wastewater, the amount of the food waste that the scrapers 310 can push, The width W, the predetermined height H, and the operating speed of the food waste remover according to the present invention.

At this time, although the interval between the scrapers 310 may be shorter than the length of the first transfer unit 110, two or more scrapers 310 may be simultaneously disposed in the first transfer unit 110. However, Since the third conveying units 110, 120 and 130 form one continuous conveying unit 100, the interval between the scrapers 310 can be longer than the length of the first conveying unit 110. [ When the interval between the scrapers 310 is set longer than the length of the first conveyance unit 110, only one scraper 310 is disposed at one point in the first conveyance unit 110 or sometimes the scrapers 310 are not disposed at all .

As described above, the pair of second conveying units 120 is a part of the conveying unit 100 which is continuous to the first conveying unit 110 as a whole to constitute one continuous conveying unit 100. In the illustrated embodiment, And the second direction is switched by the direction switching unit 220, that is, the second sprocket, to reach the third direction switching unit 230. The second direction 720 does not necessarily have to be a vertical direction as shown in the drawing, but may be a direction that is upwardly slanted upward from the second direction switching unit 220 toward the third direction switching unit 230. That is, the third direction switching unit 230 may be positioned on the right side of the second direction switching unit 220 with reference to FIG. The second transfer part 120 is configured to move in the second upward direction 720 because the scraper 310 coupled to the first transfer part 110 collects food waste So that it is separated from the wastewater remaining in the cleaning chamber bottom surface 40 and transferred. In order to efficiently discharge the food waste, it is necessary to remove the moisture to reduce the weight, and if the food waste is continuously transferred in the sewage, the food waste may be swept away from the scraper 310 by the flow of the sewage. It should be noted that the configuration in which the third direction switching unit 230 is located on the left side of the second direction switching unit 220 is considered to be a configuration that generally fails to achieve the object of the present invention. ) Does not largely deviate from the vertical, there will be no problem to achieve the object of the present invention.

Note that, in this specification, the distinction between the first transfer unit 110 and the second transfer unit 120 need not be strictly performed. That is, although the first conveyance unit 110 and the second conveyance unit 120 are clearly distinguished from each other in the linear movement interval, the curved movement interval formed by the second direction switching unit 220 may be divided into the first conveyance unit 110 , And may be referred to or interpreted as belonging to the second transfer unit 120. [ The same applies to both of the first to sixth transfer units 110, 120, 130, 140, 150, and 160, as well as between the first transfer unit 110 and the second transfer unit 120. That is, although the linear movement section is clearly defined and divided as belonging to each of the transportation sections, the curved movement section formed by the first to sixth direction switching sections 210, 220, 230, 240, 250, It may be mentioned or interpreted as belonging to one of the conveying portions adjacent to the direction switching portion or belonging to the other side.

The first guide surface 410 extends from the cleaning chamber bottom surface 40 so as to be parallel to the second transfer portion 120. That is, the first guide surface 410 refers to a bottom surface or wall portion extending from the bottom surface 40 of the cleaning chamber in the second direction 720 to the vicinity of the third direction switching portion 230. The first guide surface 410 is spaced apart from the second transfer unit 120 by the predetermined height H. This is because when the scrapers 310 are moved along the second conveyance unit 120, the end portions 313 of the scrapers 310 contact the first guide surface 410 So that the food waste collected in the washing chamber bottom surface 40 is continuously moved along the first guide surface 410.

The first guide surface 410 is spaced apart from the right side of the second transfer part 120 as shown in FIG. 3 because the first guide surface 410 extends from the bottom surface 40 of the cleaning chamber 40 . The first guide surface 410 is composed of the 1a curved portion 411, the first straight portion 413, and the 1b curved portion 415. The first rectilinear section 413 is formed in parallel with the linear movement section of the second transfer section 120 and connects the first 1a curved section 411 and the first 1b curved section 415. The 1a curved portion 411 extends from the second transfer portion 120 by a predetermined height H to a curved portion formed by the second direction switching portion 220, ) And the lower end of the first rectilinear section (413). The first bending portion 415 is connected to the second transfer portion 120 by a predetermined height H with respect to the curved portion formed by the third direction switching portion 230, (413). The radius of curvature of the first and second curved portions 413 and 415 is related to the size of the second and third direction switching portions 220 and 230. That is, in the illustrated embodiment, when the PCD (pitch circle diameter) of the second and third sprockets constituting the second and third direction switching units 220 and 230 is larger, the first and the first b curve portions 413 and 415 Becomes larger, and therefore, a curved movement section that is not abrupt and becomes smoother is formed. When the scraper 310 having the predetermined height H is moved along the second conveyance unit 120, the first and second curved portions 413 and 415 of the first guide surface 410 are also scraped The end portion 313 of the second elastic member 310 should be positioned so as to be in contact with or nearly touching.

The pair of third conveying units 130 is a part of the conveying unit 100 which is continuous to the first conveying unit 110 and the second conveying unit 120 and constitutes a single continuous conveying unit 100. In the illustrated embodiment, The third direction switching unit 230, that is, the third sprocket, which is turned to move in the third lateral direction and reaches the fourth direction switching unit 240. [ In the illustrated embodiment, the third direction 730 is in the horizontal direction, but it may be a direction slightly deviated from the horizontal direction.

The second guide surface 420 extends from the first guide surface 410 so as to be parallel to the third transfer part 130. That is, the second guide surface 420 extends from the first bend portion 415 of the first guide surface 410 in the third direction 730 to the bottom surface portion extending to the vicinity of the fourth direction switching portion 240 Quot; The second guide surface 420 is spaced apart from the third transfer unit 130 by the predetermined height H. This is because when the scrapers 310 are moved along the third conveyance unit 130, the end portions 313 of the scrapers 310 as well as the first and second conveyance units 110 and 120 are separated from the second guide surfaces 420 So that the food waste collected in the washing chamber bottom surface 40 can be continuously moved along the second guide surface 420 following the first guide surface 410. In other words,

3, the second guide surface 420 is spaced apart from the first guide surface 410. The second guide surface 420 is spaced apart from the third conveyance part 130 (refer to FIG. 3) As shown in Fig. The second guide surface 420 is composed of the 2a straight portion 421 and the 2b straight portion 423. The 2a straight line portion 421 is formed to be parallel to the linear movement section of the third conveyance section 130, but is formed to have a shorter length. Even if the length of the 2a straight portion 421 is formed to be very short, the main object of the present invention can be achieved without difficulty. However, considering the realistic aspect, it may be problematic to make the length thereof very short. That is, the smooth movement of the scraper 310 passing from the first guide surface 410 to the second guide surface 420 via the third direction switching portion 230 and the smooth movement of the food waste conveyed by the scraper 310 The length of the 2a straight line portion 421 should be formed to some extent or more in consideration of whether or not it can fall safely into the rejection rejection 620 without leaving the rejection rejection 620. [

The second straight line portion 423 is a portion extending downward from the right end portion (reference in FIG. 3) of the second straight line portion 421, and the debris removal portion 620 is located below the second straight portion 423. The food waste pushed by the scraper 310 along the second straight line portion 421 of the second guide surface 420 reaches the right end of the second straight line portion 421 and moves along the second straight line portion 423 Falls to the bottom and is discharged to the residue removal unit 620. The second straight line portion 423 may be formed so as to include a part of the curved portion or may be formed as a curved portion (for example, a sector, a semi-circle, etc.) unlike the name.

The fourth direction switching unit 240, that is, the pair of fourth sprockets in the illustrated embodiment, is connected to the driving unit 510 and is rotationally driven to move the third conveying unit 130 made of a chain. As described above, since the third transfer unit 130 is a part constituting one continuous transfer unit 100 as a whole together with the first and second transfer units 110 and 120, the one transfer unit 100 are driven by the driving unit 510 to continuously move in a specific direction. The movement trajectory of the one continuous transporting unit 100 driven by the driving unit 510 is determined by the first to fourth direction switching units 210, 220, 230, and 240. The fourth to sixth conveyance units 140, 150 and 160 and the fifth and sixth direction switching units 250 and 260 to be described later are components necessary for determining the movement trajectory of the one continuous conveyance unit 100 And is only indicative of one possible embodiment.

In the illustrated embodiment, the driving unit 510 is a hydraulic motor, and the driving shaft of the hydraulic motor is connected to a fourth direction switching unit shaft 243 that interconnects the pair of fourth sprockets through a coupling 520 . In addition to the hydraulic motor, an electric motor, a small engine, and the like, may be used as the driving unit 510, for example, an arbitrary power generation device that generates rotational power. In some cases, a combination of a power generating device for generating a non-rotational power such as a linear motion and a device for converting such non-rotational power into rotational power may be used. Depending on the type of the driving part, a reduction gear may be additionally provided for increasing the rotational driving force, that is, the torque. In the illustrated embodiment, the driving shaft of the driving unit 510 and the fourth direction switching unit shaft 243 are slightly eccentrically eccentrically connected to each other, This ensures stable power transmission even when the angle of the motor is slightly deviated.

The debris removal unit 620 is positioned below the driving unit 510 or below the second b rectilinear section 423 of the second guide surface 420. [ As described above, the food waste pushed by the scraper 310 along the second straight line portion 421 of the second guide surface 420 reaches the right end portion (reference in FIG. 3) of the second straight line portion 421, 2b rectilinear section 423, and is discharged to the residue rejection 620. [0064]

The space in which the debris receipt 620 is located is a debris storage compartment 610 and the debris storage compartment 610 is provided with a door portion 613 for carrying in and out the debris receipt 620. The door portion 613 is normally closed when the food waste dehydrator according to the present invention is in operation, and when the automatic drainage device of the present invention is completed after the debris collection operation is completed, the debris rejection 620 to the outside. The empty residue remover 620 in which the food remnants are empty can be brought into the residue room 610 again, and then the door portion 613 can be closed.

The debris removal unit 620 includes a plurality of perforation holes (not shown) at its bottom portion, and the bottom portion is configured to be spaced a certain distance from the bottom surface of the debris collection chamber 610 where the debris removal unit 620 is located . The wastewater discharged from the food waste accumulated in the debris removal unit 620 may be discharged to the bottom surface of the debris water storage room 610 through the plurality of perforation holes at the bottom of the debris removal unit 620.

A drain valve 615 may be provided on the lower side of the bottom surface of the residue accommodation chamber 610 to discharge the waste water discharged to the bottom surface of the residue accommodation room 610 to the outside.

The lower end of the door portion 613 may be spaced a predetermined distance from the bottom surface of the waste water storage chamber 610 so that wastewater can be stored in the bottom surface of the waste water storage chamber 610. If the lower end of the door portion 613 coincides with the bottom surface of the residue water chamber 610 or is positioned further downward, unintentional discharge of the wastewater may occur when the door portion 613 is opened. It is for this reason. By providing the door portion 613 as described above, even if the drain valve 615 is opened before the door portion 613 is opened and the wastewater can not be discharged to the outside in advance, the wastewater can flow out through the door portion 613 So that the sewage can be discharged to the outside through the drain valve 615 even after the door portion 613 is opened.

A third guide surface 430 having a plurality of perforation holes 431 may be disposed in the vicinity of the first direction switching unit 210. The third guide surface 430 extends upward from the bottom surface 40 of the cleaning chamber and is spaced apart from the first transfer unit 110 by the predetermined height H. [ That is, the third guide surface 430 may be spaced apart from the first conveying unit 110 by a predetermined height H by side or side of the first conveying unit 110, which is engaged with the first direction switching unit 210, And extends upward from the washing chamber bottom surface 40.

Beyond the third guide surface 430, a waste water temporary storage 30 is located. That is, the waste water temporary storage 30 is located on the opposite side of the first direction switching unit 210 with respect to the third guide surface 430. The wastewater temporary storage 30 is discharged to the washing chamber bottom surface 40 as described later and the wastewater from which the food waste is separated flows over the plurality of perforation holes 431 of the third guide surface 430 and temporarily At the storage place, the wastewater stored in the wastewater temporary storage 30 is transferred to the wastewater tank 70 by the wastewater transfer pump 50.

The first direction 710 which is the moving direction of the first transfer unit 110 is the direction from the first direction switching unit 210 to the second direction switching unit 220 and the third guide surface 430 is the direction The scraper 310 moved along with the first transfer part 110 is moved in the direction of the first guide part 430 after the end part 313 of the scraper 310 is moved along the third guide surface 430, Is moved along the bottom surface (40).

Hereinafter, the operation of an embodiment of the apparatus for automatically discharging food waste according to the present invention will be described.

As described above, each of the first to third conveyance units 110, 120, and 130 in the automatic waste food waste ejection apparatus according to the present invention includes one continuous conveyance unit 100 moved by the driving unit 510 And the scraper 310 is continuously moved along the bottom surface 40 of the washing chamber 40, the first guide surface 410 and the second guide surface 420 to remove the food waste discharged toward the washing chamber bottom surface 40 It is once again to be reminded that this is a component that carries it to the debris removal 620.

First, the food garbage collection container (not shown) is cleaned by the cleaning device 20 provided in the cleaning chamber 10. In the illustrated embodiment, the collection container can be cleaned by inserting the cleaning device 20 into the inside while being supported in an inverted state. Alternatively, it may be flushed upright as in the normal use condition of the collection container and then turned over for sewage discharge. In addition, depending on the state of the collection container, only the inside can be cleaned, and the inside and outside can be cleaned.

The wastewater generated during the collection of the collection container, that is, the mixture of food waste and wash water adhering to the collection container, will be discharged toward the bottom surface 40 of the cleaning chamber. The food waste contained in the wastewater discharged to the washing chamber bottom surface 40 is separated from the waste water by the scrapers 310 that are coupled to the first transfer unit 110 and moved together with the first transfer unit 110. In this case, And is conveyed along the washing chamber bottom surface 40. The food waste and the remaining wastes are separated from each other by a plurality of perforation holes 311 formed in the scraper 310. If the number of the scrapers 310 is more than one, the separation and the transfer are repeatedly performed at a predetermined time interval to separate the food waste that has not been separated by the preceding scraper 310, Thereby separating the food waste from the sewage discharged from the sewage disposal facility. The remaining wastewater separated from the food waste remains in the washing chamber bottom surface 40 and passes through the plurality of perforation holes 431 formed in the third guide surface 430 to reach the temporary storage tank 30 ≪ / RTI > The wastewater flowing into the wastewater temporary storage 30 and being stored is sucked into the wastewater suction pipe 55 by the wastewater transfer pump 50 and is transferred to the wastewater tank 70.

The food waste conveyed along the washing chamber bottom surface 40 by the scraper 310 is conveyed from the vicinity of the second direction switching unit 220 to the vicinity of the third direction switching unit 230 along the first guide surface 410 The second guide surface 420 and then to the second rectilinear section 423 and drops toward the debris catcher 620. The second guiding surface 420 is then moved toward the fourth direction switching section 240,

The scraper 310 moves along the curved trajectory along the fourth direction switching unit 240 to switch the moving direction and then to the first direction switching unit 210. [ As shown in FIG. As described above, since each of the first to third transfer units 110, 120, and 130 is a part forming one continuous transfer unit 100 moved by the driving unit 510, the first transfer unit 110, The conveying means 100 connected to the third conveying unit 130 through the second conveying unit 120 is further connected to the first conveying unit 110 to form one continuous conveying unit. That is, in the illustrated embodiment, a chain driven by a sprocket connected to a hydraulic motor is capable of operating as one continuous transport means 100 until its trajectory is drawn in a closed curve.

Accordingly, the scraper 310 having passed through the fourth direction switching unit 240 is returned to the first direction switching unit 210, and the third guide surface 430 ). The food waste that is separated and collected by the scraper 310 moved together with the first transfer unit 110 and is not transferred is discharged from the washing chamber bottom surface 40 through the perforation holes of the third guide surface 430 431 to flow into the waste water temporary storage 30, and then flows into the waste water temporary storage 30 to be blocked by the third guide surface 430. The food waste that is prevented from being introduced into the waste water temporary storage 30 by the third guide surface 430 is accumulated on the third guide surface 430. The food waste accumulated on the third guide surface 430 before the joining of the first conveyance unit 110, The waste water is separated and collected from the waste water by the scrapers 310 passing through the waste water collecting pipe 430 and conveyed toward the waste rejection 620. At this time, if the amount of the wastewater discharged into the washing chamber bottom surface 40 is large, that is, if the level of the wastewater is high, the wastewater may interfere with the collection and transportation of the food waste accumulated on the third guide surface 430 . Therefore, the wastewater transfer pump 50 is operated from time to time to transfer the wastewater stored in the wastewater temporary storage 30 to the wastewater tank 70 so that the level of the wastewater does not become too high in the cleaning chamber bottom surface 40, So that the wastewater from the bottom surface 40 can be introduced into the wastewater temporary storage 30.

The construction for returning the scrapers 310 from the fourth direction switching unit 240 back to the first direction switching unit 210 is similar to that of the first to third transfer units 110, 220, 230, and 240, the driving unit 510, and the like, as shown in FIG. In the illustrated embodiment, the fourth conveying unit 140 is moved from the fourth direction switching unit 240 to the fifth direction switching unit 250 in a direction substantially opposite to the third direction 730, A fifth conveying unit 150 which is moved downward from the switching unit 250 to the sixth direction switching unit 260 in a direction substantially opposite to the second direction 720, And a sixth conveying unit 160 that is laterally moved in a direction substantially opposite to the first direction 710 to the direction switching unit 210. However, the sixth conveying unit 160 is only one embodiment, It is not. For example, if the surrounding condition permits, the conveying means 100 may be directly connected from the fourth direction switching unit 240 to the first direction switching unit 210. Alternatively, the transporting unit 100 may be directly connected to the first direction switching unit 210 after passing through only the fifth direction switching unit 250 in the fourth direction switching unit 240. At this time, the fifth direction switching unit 250 may be arbitrarily positioned somewhere in the middle of the position of the illustrated embodiment and the upright position of the first direction switching unit 210.

In the illustrated embodiment, the fourth sprocket, which is the fourth direction switching portion 240, is coupled to a tensioner or a tension bearing 530. That is, by moving the tensioner 530 coupled with the fourth sprocket in the lateral direction with reference to FIG. 3, the tension applied to the conveying means 100, that is, the chain is appropriately adjusted to move the scraper 310 by the conveying means 100 And the food waste can be smoothly transported. When the tension is strong, the rotational motion of the angular switching parts 210, 220, 230, 240, 250 and 260 and the angular switching part shafts 213, 223, 233, 243, 253 and 263 is disturbed, 310 may not move smoothly and an excessive load may be applied to the driving unit 510. If the tension is weak, the deflection of the conveying means 100 may be partially caused excessively, and the movement of the scraper 310 may not be performed in a desired trajectory. For example, when excessive sagging occurs in the first conveyance part 110, the scraper 310 can not stand upright vertically, and the slant is laid down and touches the bottom surface 40 of the cleaning chamber 40, so that it is difficult to push the food waste well will be.

The first, second, third, and fourth feeders 110, 120, 130, 140, and 160 of the apparatus for automatically discharging food waste according to the present invention protect the respective feeders and guide each feeder along the intended trajectory. First, second, third, and fourth conveyance unit guides 113, 123, 133, 143, and 163, respectively. In the illustrated embodiment, feeder guides 113, 123, 133, 143 and 163 are provided for protecting and guiding the chains constituting each conveying portion, the cross section of which is entirely enclosed by the chain, And the opening is provided on one side. Specifically, the cross section may be referred to as a "C" shape, or may be formed as a "C" shape. The opening for chain access is facing inward. That is, a pair of openings formed respectively in the pair of conveyance guide guides 113, 123, 133, 143, 163 for guiding and guiding the pair of chains are formed in directions opposite to each other.

A guide fixing portion (not shown) may be provided for each conveying portion guide to fix and support the conveying portion guide.

On the other hand, there is no fifth conveyance section guide corresponding to the fifth conveyance section 150, which is the chain tensioner 530. That is, as the tension of the chain is adjusted by the tensioner 530, the position of the fifth feeding part 150 may be largely varied from side to side, which is unsuitable for providing the feeding part guide. Accordingly, 150 are shown as being not provided with a conveyance guide.

Both end portions of the conveyance unit guides 113, 123, 133, 143, and 163 may be configured to gradually expand toward the outside in the vertical direction as shown in FIG. This is to prevent the risk that each conveying portion, that is, the chain enters into the conveying guide and contacts or gets caught by the relatively sharp cutting surface of the upper or lower portion of the conveying portion guide end, and is damaged. In other words, the chain may be temporarily entangled due to various external factors during operation. The chain may be instantaneously moved to the upper portion or the lower portion of the end portion of the conveying portion guide by such swaying. When a part of the chain thus moved is brought into contact with or caught by the above-mentioned sharp cutting surface, an excessive load is instantaneously applied to the chain by the driving force of the driving unit 510 pulling the chain, Can occur. If the end portion of the feeder guide is formed in such a shape that gradually flares up and down in this manner, even if the chain instantaneously slips, the chain is not shifted toward the sharp cut surface but is formed at an oblique portion on the upper and lower sides of the feeder guide end, So that breakage or damage of the chain can be prevented.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, another embodiment of an apparatus for automatically discharging food waste according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 6 is a view showing another embodiment of the apparatus for automatically discharging food waste according to the present invention, and FIG. 7 is an enlarged view of a part 'A' of FIG. 6 in an enlarged scale.

Another embodiment of the apparatus for automatically discharging food waste according to the present invention shown in FIGS. 6 and 7 further includes a lower rail 330. The lower rail 330 may include a debris guide portion 331, which will be described later.

The residue guide portion 331 is seated on the bottom surface 40 of the cleaning chamber 40 and forms a debris inlet portion 350 which is a transfer passage for the food waste discharged to the bottom surface 40 of the cleaning chamber 40. To this end, the residue guide portion 331 is formed in a long channel shape along the conveying direction of food waste in the bottom surface 40 of the washing chamber, and is formed of a channel bottom 333 and a channel side 335. In the cross-sectional shape of the channel, it is preferable that the bottom surface 333 of the channel is formed flat to move the scraper 310 and to transport the food waste by the scraper 310. The shape of the pair of channel side surfaces 335 can be variously formed as long as it does not interfere with the movement of the scraper 310. However, in order to minimize the backward detachment of food waste carried by the scraper 310 back through the side of the scraper 310, it is preferred that it is formed of an upright wall positioned substantially adjacent to the side of the scraper 310 Lt; / RTI > Therefore, the distance between the width of the residue guide portion 331 and the channel side surfaces 335 must be larger than the predetermined width W of the scraper 310 for smooth movement of the scraper 310, ) Is minimized.

The lower rail 330 may further include a pair of the first conveyance unit guides 113 described above. At this time, the pair of first transfer part guides 113 may be formed integrally with the residue guide part 331. The width of the residue guide section 331 is slightly larger than the predetermined width W of the scraper 310 and the first chain 110 and the first transfer section 110 are at least partly enclosed One embodiment of the shape of the integrally formed first transfer part guide 113 and the remnant guide part 331 is shown in the figure as well, since a pair of first transfer part guides 113 formed so as to be located on both sides of the scraper 310 7, respectively.

In the present embodiment, the first transfer unit 110 is configured to be spaced apart from the bottom of the cleaning chamber 40 by the predetermined height H from the residue guide unit 331. The scraper 310 moves the food waste discharged toward the washing chamber bottom surface 40 to the debris removal unit 620 through the debris guide unit 331, the first guide surface 410 and the second guide surface 420, .

A lower rail support portion 340 may be further provided on a lower side of the first conveyance portion 110 which is a part of the lower rail 330. The lower rail supporting portion 340 supports the first conveying portion guide 113 which surrounds the first conveying portion 110 from the lower side and the lower rail supporting portion 340 supports both sides As well. Thus, even if the sewage falls from the upper side of the cleaning chamber 10, the lower rail 330 does not separate from the predetermined position, and the scraper 310 can reliably collect food waste.

In the present embodiment having the lower rail 330, the wastewater falling from the upper side of the cleaning chamber 10 is introduced into the drainage guide portion 331 in the channel form, unlike the previous embodiment in which the lower rail 330 is not provided It is necessary to let it all flow into the residue inflow section 350. This is because there is no way that the scrapers 310 can collect and transport the food waste contained in the wastewater when the food waste falls off the residue guide portion 331.

Accordingly, the other embodiment of the apparatus for automatically discharging food waste according to the present invention may further include an inclined bottom surface 43 extending upward from the upper side of the lower rail 330 in an upward direction. More specifically, the lower end of the inclined bottom surface 43 is connected to the upper side of the first conveyance guide 113 of the lower rail 330, and the upper end of the inclined bottom surface 43 is extended upward Whereby the wastewater falling from the upper side of the cleaning chamber 10 to the inclined bottom surface 43 flows into the residue inlet portion in the residue guide portion 331 via the upper side of the lower rail 330).

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of a scraper and a scraper supporting portion of a food waste remover according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 8 is a view showing an embodiment of a scraper and a scraper supporting part of the apparatus for automatically discharging food waste according to the present invention, and FIG. 9 is a view showing another embodiment of the scraper and the scraper supporting part.

The scraper 310 is coupled to and supported by the scraper support portion 317 and both ends of the scraper support portion 317 are respectively coupled to the conveying means 100, that is, two adjacent chain pins 100a of the chain.

The scraper support 317 includes a support center portion 317a extending laterally and engaged with the scraper bottom portion 315 and a pin engagement portion 317b coupled to the chain pin 100a of the chain positioned on both sides, . The support center portion 317a is disposed in a direction transverse between the pair of chains for engagement with the scraper 310 while the pin engagement portion 317b is disposed in the axial direction of the chain pin So that the cross-section of the scraper support portion 317 as a whole has a rectangular shape with one side opened.

The pin coupling portions 317b on both sides are respectively coupled with two adjacent chain pins 100a. Whereby the scrapers 310 coupled to the scraper support 317 can always be stably held in a direction substantially perpendicular to the direction of movement of the chain. This is also the case when the chain moves along a curved trajectory along the sprocket circumference.

As described above, the scrapers 310 can be coupled to the support center portion 317a of the scraper support portion 317 at a bottom portion 315 thereof, and welding or the like can be used as a joining method. At this time, if necessary, the pair of conveying means 100 having a pair of scrapers 310 may be arranged in a direction to be obliquely crossed rather than vertically. In this case, for smooth operation of both chains, the scraper support portion 317 should be disposed in a direction perpendicular to the scraper support portion 317, and only the scraper 310 coupled to the scraper support portion 317 should be angularly coupled.

Unlike the above embodiment, the scraper 310 and the scraper support 317 may be integrally formed as shown in Fig. That is, the scraper 310 and the scraper support 317 can be formed by bending one side of the scraper 310 to form the scraper support 317 or vice versa.
