DETAILED DESCRIPTION

[0026] In order to better understand the above technical solutions, the above technical solutions will be described in detail below in combination with the drawings of the specification and specific embodiments.

[0027] Embodiment 1

[0028] The embodiment of the present application provides a vertical continuous composting aerobic fermentation bin, referring to Figure 1 , 2 , comprising a bin body 1 and a filter cartridge 2, the bin body 1 is in a cylindrical shape, the top and bottom of the bin body 1 are respectively provided with a feeding port 11 and a discharging port 12, and the bin body 1 is fixedly installed by a metal stand or a suspension. The filter cartridge 2 is coaxially arranged in the bin body 1, the filter cartridge 2 is hollow inside, and a plurality of filter holes 21 are formed through the outer wall of the part of the filter cartridge 2 located in the bin body 1, and the bottom of the filter cartridge 2 extends out of the bin body 1 and is connected with a sewage pipe. The bottom of the bin body 1 is provided with a switch assembly 3 for opening and closing the discharging port 12, a turning and stirring assembly for stirring the contents in the bin body 1 is arranged between the bin body 1 and the filter cartridge 2 in the bin body 1, and a pump gas assembly for pumping air between the space between the outer wall of the filter cartridge 2 and the inner wall of the bin body 1 is further arranged on the bin body 1.

[0029] When a worker is composting garbage, the bottom discharging port 12 of the bin body 1 is closed, the garbage is filled from the top feeding port 11 of the bin body 1, the wastewater in the garbage seeps into the filter holes 21 of the filter cartridge 2 and is discharged to the sewage pipe, so as to avoid pollution of the environment caused by the wastewater leaking out, air or oxygen is pumped into the bin body 1 by the pump gas assembly, and the contents in the bin body 1 are turned and stirred periodically or continuously by the turning and stirring assembly in the bin body 1, so that the oxygen fully contacts the contents, thereby providing a good growth environment for aerobic bacteria. The bin body 1 can be continuously filled with garbage for multiple times, when the first batch of garbage filled in the bin body 1 is fermented for a sufficient number of days, the switch assembly 3 can be opened at any time, the garbage in the bin body 1 is discharged by gravity, and then the bin body 1 is closed to continue the composting and fermentation work. The continuous garbage supplementing and continuous fermentation work can be realized, the labor intensity is reduced, and the composting and fermentation efficiency is improved.

[0030] Wherein, the stirring assembly comprises several rows of movable paddles 41 arranged on the outer wall of the filter cylinder 2 in vertical direction and at least one row of fixed paddles 42 arranged on the inner wall of the bin body 1. In the embodiment of the application, three rows of movable paddles 41 and one row of fixed paddles 42 are arranged. The filter cylinder 2 is rotationally connected to the bin body 1. Specifically, a driving source 6 is arranged at the bottom of the bin body 1, and the driving source 6 is a servo motor. The output shaft of the servo motor is drivingly connected to the filter cylinder 2. In the embodiment of the application, a driven gear ring is coaxially arranged on the outer portion of the filter cylinder 2, and a driving gear is coaxially and fixedly connected to the output shaft of the servo motor. The driving gear is engaged with the driven gear ring. The blades of the movable paddles 41 and the fixed paddles 42 are arranged in an inclined manner, and the movable paddles 41 and the fixed paddles 42 are arranged in the same inclined direction. The servo motor is rotated in a forward direction to drive the filter cylinder 2 and the movable blades on the filter cylinder 2 to rotate in the circumferential direction of the bin body 1. When the lower end of the blade of the movable paddle 41 is located on the front side in the rotating direction, the movable blade pushes the content in the bin body 1 upward to continuously stir the content. When the higher end of the blade of the movable paddle 41 is located on the front side in the rotating direction, the movable blade pushes the content in the bin body 1 downward to accelerate the compression and movement of the content in the bin body 1.

[0031] With reference to Figure 3 In the embodiment of the application, the air pumping assembly comprises an air inlet pipe 51. The outer wall of the bin body 1 is provided with a sandwich layer, and the sandwich layer is an air separation layer 52. The air inlet pipe 51 is connected to the outer wall of the bin body 1. One end of the air inlet pipe 51 is connected to an air pump, and the other end of the air inlet pipe 51 is in communication with the air separation layer 52. The lowermost fixed paddle 42 is integrally and fixedly connected with a connecting pipe 53. The connecting pipe 53 is hollow. The connecting pipe 53 is fixedly connected to the inner wall of the bin body 1 and in communication with the air separation layer 52. The bottom of the connecting pipe 53 is close to the lower edge of the fixed paddle 42. A plurality of air inlet holes 54 are arranged on the side of the lower edge of the fixed paddle 42 along the axial direction of the connecting pipe 53.

[0032] Air or oxygen is pumped into the air separation layer 52 by the air pump, and the gas enters the bin body 1 from the air inlet holes 54 of the fixed paddle 42, and then flows upward to fully contact the content in the bin body 1. The connecting pipe 53 is connected to the middle portion of the fixed paddle 42, and the lower surface of the connecting pipe 53 protrudes from the bottom wall of the blade of the fixed paddle 42, so that a triangular space is formed between the bottom of the connecting pipe 53 and the blade of the fixed paddle 42. When the content in the bin body 1 flows forward and backward during the rotation of the filter cylinder 2, the content is prevented from entering the connecting pipe 53 from the air inlet holes 54 to block the connecting pipe 53. The air separation layer 52 can also enhance the heat preservation effect during the fermentation of the content in the bin body 1, and improve the compost fermentation effect.

[0033] In the embodiment of the present application, the switch assembly 3 comprises a slagging disc 31 and a driving cylinder 32. The slagging disc 31 is fixed at the bottom of the filter cylinder 2, is located below the discharge port 12 of the bin body 1 and is larger in size than the discharge port 12, and the top wall of the slagging disc 31 is conical and coaxial with the bin body 1. The driving cylinder 32 is arranged below the slagging disc 31 and is used to drive the slagging disc 31 to vertically ascend and descend. In other embodiments, an electric push rod, a hydraulic lifter or other devices can be used to drive the slagging disc 31 and the filter cylinder 2 to ascend and descend relative to the bin body 1. Specifically, the slagging disc 31 is connected to the filter cylinder 2 above the driving source 6. The filter cylinder 2 is provided with a support plate and a coaxially connected support tube below the driving source 6. The support plate is fixed on the support tube. The bottom of the filter cylinder 2 is coaxially and rotatably connected to the support tube. The driving source 6 is fixedly installed on the support plate. The piston rod of the driving cylinder 32 is connected to the support plate. The driving cylinder 32 is extended and retracted to push the support plate, the support tube and the filter cylinder 2 above to ascend and descend. The driving source 6 is actuated to drive the filter cylinder 2 to rotate relative to the support tube.

[0034] When the slagging disc 31 ascends and the edge of the discharge port 12 of the bin body 1 abuts against the conical top wall of the slagging disc 31, the discharge port 12 of the bin body 1 is closed, so that the contents in the bin body 1 can be normally composted. When the composting time of the contents at the bottom layer of the bin body 1 reaches the required composting time, for example, 4-6 days, the slagging disc 31 is driven by the driving cylinder 32 to descend, so that a gap is exposed between the slagging disc 31 and the discharge port 12 of the bin body 1. Under the action of gravity, the contents in the bin body 1 can be naturally discharged from the gap. In order to accelerate the discharge efficiency of the contents, the filter cylinder 2 and the movable paddle 41 can be driven to rotate by the driving source 6 after the slagging disc 31 descends, so as to drive the contents in the bin body 1 to move downward at a high speed, and the contents in the bin body 1 rotating along with the bin body 1 are extruded downward by the fixed paddle 42 closest to the discharge port 12, so as to accelerate the discharge rate of the contents. When the slagging disc 31 is opened for a period of time, or the worker observes the decrease in the fermentation quality of the contents near the discharge port 12 of the bin body 1 by means of the real-time image tool with the naked eye, the slagging disc 31 is controlled to ascend to stop discharging the contents and continue the composting fermentation work.

[0035] Embodiment 2

[0036] Compared with embodiment 1, the main difference of embodiment 2 is that the slagging disc 31 and the turning and stirring assembly are different.

[0037] Reference Figure 4The fixed blades 42 are arranged in at least two rows in the vertical direction, and in the embodiment, the fixed blades 42 are two rows, and the movable blades 41 are two rows. The lowermost fixed blades 42 are located below the lowermost movable blades 41, and the upper fixed blades 42 are arranged between the movable blades 41 in a staggered manner. Each row of fixed blades 42 and movable blades 41 are circumferentially provided with a plurality of pieces. When the movable blades 41 on the filter cartridge 2 rotate, the contents in the bin 1 also rotate. If the friction between the contents and the inner wall of the bin 1 decreases so that the rotation speed of the contents approaches the rotation speed of the movable blades 41, it is difficult to achieve the stirring effect. At this time, the fixed blades 42 between the movable blades 41 limit the rotation of the contents, thereby improving the stirring and mixing effect of the contents in the bin 1.

[0038] Referring to Figure 5 Further, the wing plates 411 are horizontally extended at both ends of the lowermost movable blades 41. The projections of the wing plates 411 of the adjacent two movable blades 41 on the horizontal plane overlap, and a gap is left between the wing plates 411 of the adjacent two movable blades 41. By extending the wing plates 411, when the discharge disc 31 is opened to discharge the contents in the bin 1, the filter cartridge 2 is rotated, so that the wing plates 411 of the movable blades 41 at the lower position are rotated as the front side in the forward direction. The contents on the upper layer of the movable blades 41 slide up above the wing plates 411, and a small amount of contents can move downward through the movable blades 411 with the wing plates 411, thereby quantifying the volume of the contents discharged each time the discharge disc 31 is opened. The contents in the space below the movable blades 41 with the wing plates 411 are rotated under the action of the discharge disc 31. During the rotation process, the contents are gradually discharged from the bin 1 under the centrifugal action and the extrusion action of the lowermost fixed blades 42 in the bin 1.

[0039] After discharging a batch of contents, the discharge disc 31 is raised, and the filter cartridge 2 is reversed, so that the movable blades 41 with the wing plates 411 are reversed, and the upper contents are gradually extruded into the lower space. The purpose of quantitatively discharging the contents is achieved, which is more conducive to layering the contents in the bin 1 according to the time of being put in, and effectively intercepting the upper contents when discharging the contents, thereby improving the effect of layering and discharging the contents.

[0040] Further, a pressure sensor 412 is arranged on each of the movable paddles 41 at the lowermost layer, and the pressure sensor 412 is arranged on the bottom wall of the lower wing plate 411 of the movable paddle 41, and the pressure sensor 412 is used to detect the pressure on the bottom wall of the wing plate 411 caused by the content below the wing plate 411, and the plurality of pressure sensors 412 are connected in series with the driving source 6, and when the pressure detected by the plurality of pressure sensors 412 all exceeds a set threshold value, the driving source 6 stops / turns over. When the movable paddle 41 with the wing plate 411 in the bin body 1 rotates to push and move the content downward, because the situation in the bin body 1 cannot be observed, more content is easily moved, which causes the pressure below the movable paddle 41 to increase, and may cause the slagging disc 31, the movable paddle 41, and the bin body 1 to deform and the structure of the parts to be damaged. By arranging the pressure sensor 412 at the bottom of the lowermost wing plate 411 of each movable paddle 41, when the content below the movable paddle 41 at the lowermost layer in the bin body 1 fills the space, the content is evenly laid and slightly extruded on the wing plate 411, and then the driving source 6 is controlled to perform an action. The worker can manually set the set threshold value of the pressure sensor 412 to be 4-10 N, and when the three pressure sensors 412 are triggered at the same time, the driving source 6 is reversed, so that when the content in the bin body 1 is manually controlled to be moved to the space below the movable paddle 41 with the wing plate 411, after the cavity below the movable paddle 41 is filled, the content is automatically controlled to stop being transported downward and to start being stirred.

[0041] Because the movable paddle 41, the filter cylinder 2, and the slagging disc 31 are synchronously lifted, the movable paddle 41 is easily interfered with the fixed paddle 42, and the resistance is large during lifting. Therefore, in the embodiment, the filter cylinder includes a water permeation cylinder 23 and a mounting cylinder 24, the top of the bin body 1 is fixedly provided with a support 13, the top end of the water permeation cylinder 23 is coaxially and rotatably connected to the support 13, and the support 13 supports the water permeation cylinder 23. The slagging disc 31 is arranged on the mounting cylinder 24, the top of the mounting cylinder 24 is coaxially and slidably arranged in the bottom of the water permeation cylinder 23, the water permeation cylinder 23 and the mounting cylinder 24 are coaxially and linearly slid by cooperation of a guide strip and a guide groove 25, and the guide strip and the guide groove 25 can be arranged on any one of the water permeation cylinder 23 and the mounting cylinder 24, or can be staggered between the water permeation cylinder 23 and the mounting cylinder 24. By using the cooperation structure of the guide strip and the guide groove 25, when the driving source 6 drives the mounting cylinder 24 to rotate, the water permeation cylinder 23 and the movable paddle 41 outside the water permeation cylinder 23 can be synchronously driven to rotate, and when the slagging disc 31 is vertically lifted, the support 13 can limit the water permeation cylinder 23.

[0042] Referring to Figure 6As the content in the bin 1 is composted, wastewater is generated and flows downwardly onto the discharge tray 31 in addition to being drained inwardly from the water-permeable cylinder 23 to the sewer pipe. In the embodiment, the discharge tray 31 includes a guide tray 311 and a water receiving tray 312 which are spaced apart in a vertical direction and are integrally fixed to the mounting cylinder 24 of the filter cylinder 2. The top wall of the guide tray 311 is tapered, and the outer edge of the guide tray 311 is coaxially connected to a downwardly extending water guide ring 313. The outer wall of the water guide ring 313 is in the shape of a bucket, so that the lower edge of the guide tray 311 is contracted toward the mounting cylinder 24. An arc-shaped chamfer is provided at the connection between the guide tray 311 and the water guide ring 313, so that when wastewater flows toward the edge of the guide tray 311, it is guided to the water guide ring 313 and flows toward the lower edge of the water guide ring 313. The water receiving tray 312 is disposed below the guide tray 311, and the top wall edge of the water receiving tray 312 is provided with a baffle 314. A gap is left between the baffle 314 and the water guide ring 313, so that wastewater flows on the water guide ring 313 and finally drips onto the water receiving tray 312. The outer diameter of the baffle 314 is not greater than the outer diameter of the guide tray 311, so that the water receiving tray 312 does not hinder the discharge of the content in the bin 1 and avoids the content falling onto the water receiving tray 312. The water receiving tray 312 is provided with a water inlet hole 22 on the filter cylinder 2, which is flush with the inner top wall of the water receiving tray 312, so that wastewater on the water receiving tray 312 flows into the mounting cylinder 24 and finally into the sewer pipe.

[0043] Further, a plurality of water guide grooves 315 are provided at the connection between the water receiving tray 312 and the filter cylinder 2 and extend toward the outer edge of the water receiving tray 312. The water inlet hole 22 on the filter cylinder 2 is connected to the lowest recess of the water guide grooves 315, so that wastewater on the water receiving tray 312 is collected and flows into the mounting cylinder 24, and the number of water inlet holes 22 on the mounting cylinder 24 is reduced, thereby maintaining the structural stability of the mounting cylinder 24.

[0044] Further, a support can be added between the guide tray 311 and the water receiving tray 312 to maintain the gap between the guide tray 311 and the water receiving tray 312 and avoid the content on the guide tray 311 deforming the guide tray 311 downwardly.
