DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] Next, embodiments of the present invention will be described with reference to the attached drawings to facilitate understanding of the present invention. Note that parts not relevant to the description may be omitted from the drawings.

[0016] As shown in Figures 1 and 2, a waste treatment device 10 according to one embodiment of the present invention comprises an input section 20, an air supply section 30 and a treatment section 40, and the treatment section 40 can decompose and treat organic matter contained in the waste input from the input section 20.

[0017] As shown in Fig. 2, the input section 20 is provided closer to the front than the center in the front-rear direction of the waste processing device 10, and an input space Se is formed into which waste to be processed is input. The input space Se is a space surrounded by at least the front, rear, left and right sides by side panels 202a (see Fig. 1), side panels 202b, a front panel 206 (see Fig. 2), and a rear panel 208. The front panel 206 is tilted forward so that its upper end is located closer to the front than its lower end.

[0018] An input port 210 through which waste is input is formed on the upper side of the input space Se. This input port 210 is located on the front side of the upper part of the waste processing device 10 and is inclined so that the front end side is lower than the rear end side. This makes it easier for the user to insert waste compared to when the insertion port 210 is provided at the rear.

[0019] The insertion section 20 has an outer door 22, an inner door 24, and a link section 26. The outer door 22 is a rectangular door whose longitudinal direction is the left-right direction when viewed from the front side, and can close the insertion opening. The outer door 22 is a single-leaf door that opens via a hinge 221 having a rotation axis extending in the longitudinal direction, and can be opened upward from a closed state.

[0020] The inner door 24 is located below the input space Se, inside the outer door 22 and above the processing section 40, and the input space Se communicates with the processing section 40 only when the inner door 24 is opened. The inner door 24 has a pair of first and second receiving members 241 and 242 that are disposed in the front-rear direction and open downward, and is configured as a double-hinged door.

[0021] 3, the first receiving member 241 is a rectangular plate-like member disposed on the front side with its longitudinal direction in the left-right direction, and its upper surface is a smooth surface. The first receiving member 241 can be opened by rotating about a rotation axis AX241a (an example of a first rotation axis) extending in the longitudinal direction (left-right direction).

[0022] The second receiving member 242 is a rectangular plate-like member with a longer side in the left-right direction and a smooth upper surface, which is disposed on the rear side of the first receiving member 241. The second receiving member 242 can be opened by rotating about a rotation axis AX242a (an example of a second rotation axis) that extends in the longitudinal direction with a gap between it and the rotation axis AX241a. The width L2 of the second receiving member 242 (the dimension in the direction perpendicular to the extension direction of the rotation axis AX242a) is set to be smaller than the width L1 of the first receiving member 241 (the dimension in the direction perpendicular to the extension direction of the rotation axis AX241a). The first receiving member 241 and the second receiving member 242 function as receivers for receiving waste materials inserted through the outer door 22 in the closed state.

[0023] A closing plate 243 is provided at the tip of the first receiving member 241 on the side of the second receiving member 242 to close a gap g occurring between the closed first receiving member 241 and the second receiving member 242. The closing plate 243 is fixed to the lower surface of the first receiving member 241 in the closed state.

[0024] The link portion 26 has first connecting members 261a, 261b and second connecting members 262a, 262b, and can connect the outer door 22 and the inner door 24 together. The first connecting members 261a, 261b are rod-shaped members arranged at an interval in the direction in which the rotation axis AX241a extends. One end of the first connecting members 261a, 261b is rotatably provided around the rotation axis AX222 provided on the outer door 22, and the other end is rotatably provided on the first receiving member 241. More specifically, the other end is rotatably provided around the rotation axis AX241b arranged on the second receiving member 242 side. The rotation axis AX241b is an axis extending at an interval from the rotation axis AX241a.

[0025] The second connecting members 262a, 262b are rod-shaped members arranged at intervals in the direction in which the rotation axis AX242a extends. One end of the second connecting members 262a, 262b is rotatably provided around the rotation axis AX222 provided on the outer door 22, and the other end is rotatably provided on the second receiving member 242. More specifically, this one end is provided on the inside near the center of one end of the first connecting members 261a, 261b, and the other end is rotatably provided around the rotation axis AX242b arranged on the first receiving member 241 side. The rotation axis AX242b is an axis extending at an interval from the rotation axis AX242a. Therefore, the outer door 22 and the inner door 24 form a double door, and when the outer door 22 is opened, the inner door 24 is closed, and when the outer door 22 is closed, the inner door 24 is opened.

[0026] 1, the air supply unit 30 is provided with an air reservoir S1a formed by partitioning the inside with partition walls 412a, 422a, and an air reservoir S1b formed by partitioning the inside with partition walls 412b, 422b, respectively, at the lower left and right sides. Air introduced from the outside through the air introduction pipes 302a and 302b is stored in the air reservoirs S1a and S1b, respectively. The air reservoirs S1a and S1b are each shaped like a rectangular column having a trapezoidal bottom surface and extending in the front-rear direction. The air stored in the air reservoirs S1a and S1b is supplied to the processing unit 40. It is preferable that the air introduced from the air introduction pipes 302a and 302b passes through a space (not shown) in which a magnetic field of a preset strength is formed by a magnetic generator (not shown) and is blown out by a fan (not shown).

[0027] The processing section 40 has a receiving member 402 that receives the waste material input from the input section 20, and a processing chamber for processing the waste material placed on the receiving member 402 is formed.

[0028] The receiving member 402 is a plate-shaped metal member with a finer mesh than the size of the waste to be treated, and is longitudinal in the front-rear direction. The receiving member 402 is supported by a support member 404 at the center of the left and right sides when viewed from the front side, making it easy to attach and detach.

[0029] The processing chamber is divided into an upper processing chamber 41 and a lower processing chamber 42 by a receiving member 402 as a boundary. The upper processing chamber 41 is a chamber in which the waste material input from the input unit 20 accumulates, and forms a space S2a whose longitudinal direction is the front-rear direction. The upper processing chamber 41 is adjacent to the air reservoir S1a via a partition wall 412a, and is adjacent to the air reservoir S1b via a partition wall 412b. A thermometer 414 for measuring the temperature of the upper processing chamber 41 is provided on the rear side of the upper processing chamber 41 .

[0030] The lower processing chamber 42 is located below the upper processing chamber 41, and forms a prismatic space S2b having a rectangular cross section extending in the front-rear direction. The lower processing chamber 42 is adjacent to the air reservoir S1a via a partition wall 422a, and is adjacent to the air reservoir S1b via a partition wall 422b. A burner 424 for igniting the waste is provided at the center of the rear side of the lower processing chamber 42.

[0031] The processing section 40 further includes a plurality of upper air supply pipes 416a, 416b and lower air supply pipes 426a, 426b. The upper air supply pipes 416a and 416b penetrate the partition walls 412a and 412b, respectively, and are arranged in a staggered pattern when viewed from the tip side of the air supply pipes. The upper air supply pipes 416a and 416b are connected to the air reservoirs S1a and S1b, respectively, and can mainly supply air required for decomposing organic matter contained in waste to the upper processing chamber 41. In addition, the upper air supply pipes 416a and 416b are inclined so that the tip side (the upper processing chamber 41 side) is lower.

[0032] The lower air supply pipes 426a and 426b are disposed so as to penetrate the partition walls 422a and 422b, respectively. The lower air supply pipes 426a and 426b are connected to the air reservoirs S1a and S1b, respectively, and can supply air necessary for decomposing organic matter contained in waste mainly to the lower processing chamber 42. In addition, the lower air supply pipes 426a and 426b are inclined so that the tip side (the lower processing chamber 42 side) is lower. In addition, the upper air supply pipes 416a, 416b and the lower air supply pipes 426a, 426b are provided at an angle, thereby reducing the possibility of waste materials getting into the inside of the pipes. An opening for removing treated waste is formed on the front side of the treatment section 40, and a single-wing front door 406 (see FIG. 2) is provided for closing this opening.

[0033] Next, the waste treatment operation by the waste treatment device 10 will be described. Waste is put into the waste disposal device 10 through the input section 20. An eyebolt (not shown) is provided on the top surface of the outer door 22, and the outer door 22 is opened by pulling up a chain hung on the eyebolt. The chain is wound up by a hoist (not shown) operated by the user.

[0034] When the outer door 22 is opened, the first connecting members 261a, 261b and the second connecting members 262a, 262b pull up the first receiving member 241 and the second receiving member 242, respectively, so that the first receiving member 241 and the second receiving member 242 rotate around the rotation axis AX241a and the rotation axis AX242a, respectively, to close and form a waste receiving container.

[0035] When waste to be treated is put in through the outer door 22, the waste section is placed on the inner door 24. When the user operates the winch and lowers the chain, the outer door 22 is closed. When the outer door 22 is closed, the first connecting members 261a, 261b and the second connecting members 262a, 262b push down the first receiving member 241 and the second receiving member 242, respectively, causing the first receiving member 241 and the second receiving member 242 to rotate open around the rotation axis AX241a and the rotation axis AX242a, respectively, and the waste falls from the input space Se into the upper processing chamber 41 below and is placed on the receiving member 402.

[0036] Here, as shown in FIG. 2, the inner door 24 is configured with a first receiving member 241 and a second receiving member 242 so as to open on both sides. Therefore, compared to an inner door of the same size configured as a single-leaf door, the downward movement range of the first receiving member 241 and the second receiving member 242 (the height distance H1 from the tip of the blocking plate 243 when the inner door 24 is open to the bottom end position of the first receiving member 241 when it is closed) is smaller, and waste fed into the upper processing chamber 41 is piled up to a height H2 from the top surface of the receiving member 402. That is, more waste is processed at one time.

[0037] In addition, as shown in FIG. 3, the first receiving member 241 has a larger area compared to the second receiving member 242, and therefore tends to hold more waste than the second receiving member 242. As shown in FIGS. 4(A) to (C), as the first receiving member 241 and the second receiving member 242 gradually open, the waste placed on the first receiving member 241 slides backward along the inclined front plate 206 and the first receiving member 241 (see arrow), and tends to accumulate in the center of the upper processing chamber 41. Therefore, even though the input port 210 is provided on the front side of the waste processing device 10, waste is prevented from being unevenly accumulated on the front side of the upper processing chamber 41.

[0038] The waste material resting on the receiving member 402 is ignited by a burner 424 . After ignition, air is supplied from the air reservoirs S1a and S1b through the upper air supply pipes 416a and 416b and the lower air supply pipes 426a and 426b. The air is supplied at a controlled flow rate.

[0039] The waste is heated and pyrolyzed in an oxygen-reduced state. A ball valve (not shown) that is an air flow rate control valve is provided between the magnetic generator (not shown) and the fan (not shown). The amount of air supplied to the processing unit 40 is adjusted by this ball valve, so that the heating temperature range during decomposition is maintained at 400°C or less.

[0040] Furthermore, even if the outer door 22 is opened to add more waste while the waste is being heated, the inner door 24 closes, thereby reducing the amount of odor leaking outside. In addition, when the outer door 22 is closed, the first receiving member 241 of the inner door 24 is located on the open front side (see the two-dot chain line in Figure 2), and therefore functions as a heat shield that blocks radiant heat to the front side.

[0041] The exhaust gases produced during pyrolysis are properly treated before being released into the atmosphere. After processing is complete, the organic pyrolyzed waste is removed through the front door 406.

[0042] As described above, according to the waste disposal device 10, the inner door 24 opens on both sides, so that a larger amount of waste can be disposed of at one time.

[0043] Although the embodiment of the present invention has been described above, the present invention is not limited to the above-mentioned embodiment, and all changes in conditions that do not depart from the gist of the present invention are within the scope of application of the present invention.
