DETAILED DESCRIPTION

[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] Please see attached Figure 1-14 The perishable organic waste treatment equipment described in the present invention comprises a trash can 1, which is used to receive various perishable wastes sent from the outside, and a loading and lifting mechanism 2 connected to the trash can 1, which is used to pour the waste in the trash can 1 into a sorting platform 3 for caching. The sorting surface inside the sorting platform 3 is inclined, so that the waste automatically flows from the inclined sorting surface of the sorting platform 3 into the subsequent crushing device 4 for crushing, and an automatic opening and closing mechanism 30 is provided at the upper end of the sorting platform 3. When the trash can pours the waste into the sorting platform 3 through the loading and lifting mechanism 2, the automatic opening and closing mechanism 30 opens the top of the sorting platform 3, thereby facilitating the pouring of the waste, and at this time, some large or indecomposable waste can be manually removed directly.

[0035] The crushing device 4 connected to one end of the sorting platform 3 is used to crush the garbage transmitted from the sorting platform 3; the solid-liquid separation device 5 located at the lower end of the crushing device 4 is used to separate the solid and liquid of the garbage transmitted from the crushing device 4, wherein the waste liquid and solid garbage are respectively sent to the oil-water separator 6 and the fermentation device 7; the oil-water separator 6 located at the bottom of the solid-liquid separation device 5 is used to separate the waste liquid separated by the solid-liquid separation device 5 from oil and water and then discharge it; a fermentation device 7 is provided on one side of the solid-liquid separation device 5, which is used to ferment and decompose the solid garbage separated by the solid-liquid separation device 5.

[0036] The perishable organic waste treatment device of the present invention is installed in a frame composed of a frame 21 and a panel 20.

[0037] Specifically, the solid-liquid separation device 5 includes a spiral shaft 50, which is driven to rotate by a motor 52; a rotatable spiral blade 53 is provided on the spiral shaft 50; the spiral blade 53 is arranged through the first box body 54, the separation chamber 55 and the second box body 56, and the first box body 54, the separation chamber 55 and the second box body 56 are arranged in sequence; the top of the first box body 54 is connected with the crushing device 4, so that the garbage crushed by the crushing device directly falls into the first box body 54; the separation chamber 55 is arranged in a separation frame 57, and a liquid outlet (not shown in the figure) is provided at the bottom of the separation frame 57, and the separation chamber 55 is used to cooperate with the spiral blade 53 to perform solid-liquid separation on the garbage transmitted by the spiral blade, and one end of the second box body 56 is connected with the fermentation device 7; wherein the separated liquid flows into the oil-water separator 6 from the liquid outlet, and the separated solid garbage enters the fermentation device 7 from the second box body 56 for fermentation and decomposition.

[0038] As a further preferred embodiment, the separation chamber 55 includes two connecting tubes 550 arranged opposite to each other, and flanges (not shown in the figure) are respectively provided at both ends of the connecting tubes 550; a plurality of vertically distributed fixed rings 551 are provided between the two connecting tubes 550; a gasket 555 is installed between the plurality of fixed rings 551 and is passed through four screw rods 553 and fixed between the two connecting tubes 550 by nuts 554, and the gasket 555 is provided on the four screw rods 553; a moving ring 552 is provided between every two fixed rings 551, and each moving ring 552 is just in the space formed by four gaskets 555; the inner aperture of the moving ring 552 is smaller than the outer diameter of the spiral sheet 53; the moving ring is hung on the outer diameter of the spiral sheet, so that eccentricity is generated between the moving ring and the spiral shaft, and the moving ring is driven to swing continuously and periodically in the radial direction when the spiral shaft rotates; a gap of 0.5 mm is maintained between the fixed ring and the moving ring, and they are assembled alternately in sequence.

[0039] During specific operation, the spiral shaft 50 is driven by the motor 52 to rotate, thereby driving the spiral blade 53 to rotate. When the spiral blade 53 rotates, the garbage in the first box body is transferred forward to the separation chamber 55 for solid-liquid separation. In the separation process, since the spiral blade rotates in the fixed ring and the moving ring when the spiral shaft rotates, the spiral blade decomposes the garbage and squeezes it between the two fixed rings when it rotates, and the moving ring is hung on the spiral blade, and the moving ring 552 and the spiral shaft 50 are eccentrically arranged, when the spiral shaft rotates The movable ring is driven to swing continuously and periodically in the radial direction, so that the garbage between the two fixed rings 551 continues to be squeezed and transmitted out through the movable ring 552, and the squeezed solid garbage enters the second box body, while the squeezed liquid flows out from the liquid outlet to the subsequent oil-water separator. With such a structure, the crushed garbage can be dehydrated, and because the movable ring is in a periodic swinging state, the garbage stuck between the two fixed rings can be squeezed and cleaned, so that the two fixed rings are not easily blocked, it has a self-cleaning function and a good dehydration effect.

[0040] As a further preferred embodiment, at least one material-dispensing mechanism is provided on the screw shaft 50 in the second box body 56; the material-dispensing mechanism includes a first material-dispensing plate 90 in a T shape, and a second material-dispensing plate 91 in a T shape is provided on the first material-dispensing plate; in the present embodiment, two material-dispensing mechanisms are included, which are respectively located on both sides of the screw shaft 50. When working, the rotation of the screw shaft 50 drives the material-dispensing mechanism to rotate. Since the material-dispensing mechanism is composed of two T-shaped material-dispensing plates, the separated solid waste can be actively dispensed into the fermentation device, and the transmission effect of the solid waste is good, thereby ensuring that the solid waste enters the fermentation device quickly and effectively.

[0041] As a further preferred embodiment, a manual operation platform 8 is also provided on one side of the sorting platform, and workers can stand on it to perform some operations and maintenance on the equipment during operation.

[0042] As a further preferred embodiment, an openable and closable pressure cover is provided on the top of the pulverizing device 4, so that the pressure cover can be opened to inspect the pulverizing equipment, or to facilitate actual operation in case of a jam.

[0043] As a further preferred embodiment, the bottom of the first box body 54 is arc-shaped, and the inner walls on both sides of the first box body are inclined, and cross bars 9 are provided in the middle of the inner walls on both sides of the inclined shape; the two cross bars 9 are located on both sides of the screw shaft; in this way, when the screw shaft drives the spiral blade to rotate and drive the solid garbage to be transmitted, due to the presence of the two cross bars 9, the friction between the spiral blade and the solid garbage can be increased, thereby enabling the solid garbage to be transmitted more quickly and effectively.

[0044] As a further preferred embodiment, an air regulating assembly 10 is provided on the top of the fermentation device, see the attached Fig.14 The air regulating component 10 includes an air regulating channel 101 , one end of which is connected to a fermentation barrel 102 in a fermentation device, and a rotatable air door 103 is provided in the air regulating channel 101 .

[0045] Its working principle is as follows: when the fermentation barrel body 102 is not pumped, the internal pressure of the fermentation barrel body is greater than the external atmospheric pressure, the fermentation barrel body 102 forms a positive pressure, and the damper is closed; when the fan inside the fermentation barrel body pumps air, the internal pressure of the fermentation barrel body is less than the external atmospheric pressure, and the fermentation barrel body forms a negative pressure. The internal pressure turns the damper open and automatically replenishes air into the barrel, thereby automatically realizing the air intake and exhaust functions.

[0046] The perishable organic waste treatment equipment of the present invention has a compact overall structure and can realize garbage sorting, crushing, solid-liquid separation and step-by-step treatment of solid waste and liquid waste. The whole process is automated, which reduces labor costs, improves the treatment efficiency of perishable waste, and has good practicality and promotion value.

[0047] The above are only specific application examples of the present invention and do not constitute any limitation on the protection scope of the present invention. Any technical solution formed by equivalent transformation or equivalent replacement shall fall within the protection scope of the present invention.
