TECHNICAL FIELD

[0001] The present application relates to the technical field of perishable garbage biological drying treatment, and particularly relates to a novel perishable garbage biological drying feeding and discharging system. BACKGROUND

[0002] With the acceleration of urbanization, the problem of household garbage disposal is increasingly prominent. Among them, perishable garbage, as the largest part of household garbage, has a high water content and is prone to rot and deterioration, bringing great difficulties to garbage disposal. The traditional perishable garbage disposal methods mainly include landfill and incineration. However, the landfill method is easy to cause soil and groundwater pollution, and the incineration method may produce toxic and harmful gases, causing secondary pollution to the environment. Therefore, it is an urgent need to find a new and environmentally friendly method for disposing of perishable garbage.

[0003] Biological drying is a method that uses the action of microorganisms to quickly remove water through biological fermentation heat, has a small demand for external heat energy supplement, and has a very outstanding reduction effect. Compared with traditional disposal methods, biological drying has the advantages of environmental protection, energy saving and resource utilization, and is an effective way to solve the problem of disposing of perishable garbage in the eastern coastal areas of China, which mainly use incineration, and to reasonably allocate existing facility resources. However, the existing biological drying technology still has some problems when disposing of perishable garbage. The current perishable garbage biological drying system mainly includes a drum type and a tower type treatment system. A large-scale mixing system is generally arranged in the middle, which realizes sufficient mixing through frequent stirring, and is supplemented by forced ventilation and oxygen supply. Compared with the traditional strip pile type treatment process, the efficiency is higher.

Detailed Implementation

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0031] like Figures 1-12 As shown, a novel biodegradable waste biological drying feeding and discharging system includes a fermentation chamber inside the cylindrical body 4 of the tower-type treatment device's outer shell. The bottom of the cylindrical body 4 is circular, forming a long cylindrical shape. A stirring system 6 is installed inside the fermentation chamber. The fermentation chamber of the cylindrical body 4 is divided into three equal parts along the height of the cylindrical body 4. Each mixing zone is interconnected. The stirring system 6 has stirring components in each mixing zone, and the cylindrical body 4 has troughs on each mixing zone. An openable and closable gate 1 is provided inside the trough. A guide rail 3 is provided on the outside of the cylinder 4. A material collection device 2, which can be moved to each mixing zone and the feed inlet by lifting or lowering, is provided on the guide rail 3. The material collection device 2 includes a hopper 201 with an opening on the side opposite to the cylinder 4. An opening part 203 is provided at the bottom of the hopper 201. A movable opening and closing stop 104 is provided on the top of the gate 1's door plate 102. The opening and closing stop 104 forms a closed state with the door plate 102 to close the trough (e.g., Figure 7 (as shown in the illustration on the left) or in the open state that abuts against the door opening part 203 (as shown in the illustration on the left) Figure 7 (As shown in the illustration on the right side of the middle section).

[0032] In this embodiment, the opening / closing stop 104 engages with the material collection device 2 by flipping and opening / closing. A first rotating shaft 103 is fixedly mounted on the opening / closing stop 104, and the first rotating shaft 103 is rotatably connected to the top of the door panel 102. The first rotating shaft 103 is equipped with a drive device to rotate it. This drive device can provide active steering drive for a motor powered by the first rotating shaft 103, or provide passive steering drive through other means such as installing a spring on the first rotating shaft 103.

[0033] In this embodiment, the opening and closing stop 104 is a triangular irregular surface with a typical cross-section that is not isosceles. The bottom plate is a smooth curve with the two long sides located on the inner side and the short sides located on the outer side. The opening and closing stop 104 is provided with a sloping part 1042 on the side away from the cylinder. The sloping part 1042 formed by the short side can fit with the sloping surface of the top sloping groove 1021.

[0034] Specifically, the opening and closing block 104 is provided with a working part 1041 on the side opposite to the barrel 4, and the length of the working part 1041 is greater than the distance between the outer side of the door plate 102 and the first rotating shaft 103, so that when the opening and closing block 104 is turned to the open state ready to cooperate with the door opening part 203, the working part 1041 extends out of the barrel 4.

[0035] Wherein, the outer side of the door plate 102 is in contact with the outer periphery of the barrel 4, and the inner side of the door plate 102 is provided with a guide block 1023 protruding outward, and the two sides of the guide block 1023 are respectively provided with a first track guide part 1024 and a second track guide part 1025 which can abut against the door opening part 203, and the first track guide part 1024 and the second track guide part 1025 are smoothly connected between them. And the first track guide part 1024 is preferably a beveled surface, so that the first track guide part 1024 can be flush with the working part 1041 on the opening and closing block 104 after opening, as shown on the right side of Figure 7 ; the second track guide part 1025 is preferably a smooth curved surface, so that the hopper 201 can move more smoothly when moving downward to move the door opening part 203. At the same time, a pushing device can be provided in the hopper 201 to facilitate the discharge of materials.

[0036] Wherein, the opening and closing block 104 is connected with the top of the door plate 102 through the first rotating shaft 103, and the opening and closing block 104 can rotate outward around the first rotating shaft 103 until the beveled part 1042 is in contact with the top beveled groove 1021, at this time the working part 1041 and the first track guide part 1024 on the upper part of the inner side of the door plate 102 are in the same plane, so that the hopper 201 can be more conveniently driven to move downward to open the door plate 102.

[0037] In this embodiment, the bottom of the door plate 102 is provided with a second rotating shaft 101 which is rotatably connected with the inner wall of the groove part, and the outer side of the bottom of the door plate 102 is provided with a bottom beveled groove 1022; the second rotating shaft 101 is cylindrical and fixed in the middle position of the lower part of the door plate 102, and is connected with the bottom beveled groove 1022 and can be fitted in the pre-designed groove part of the outer wall of the barrel 4. The second rotating shaft 101 is provided with a reset structure, which can be a reset spring arranged on the second rotating shaft 101, so that the door block 1 can be rotated to open and close by the reset spring on the second rotating shaft 101 after being separated from the hopper 201, until the door plate 102 is reset to be in contact with the barrel 4.

[0038] In this embodiment, the hopper 201 is shovel-shaped, and a plurality of rows of sliding blocks 202 are symmetrically arranged on the left and right outer surfaces. The sliding blocks 202 are arranged in correspondence with the sliding grooves of the guide rails 3, that is, the aggregate collecting device 2 is assembled with the guide rails 3 through the sliding blocks 202 and slides up and down along the guide rails 3. The opening door part 203 is in the shape of a wedge as a whole, and is arranged at the edge of the hopper 201 opposite the cylinder 4. The outer side of the opening door part 203 is flush with the end surface of the hopper 201, and the inner side is in the shape of a concave arc. When the opening and closing blocking piece 104 at the top of the blocking door 1 is rotated to be in close contact with the top inclined chute 1021, the working part 1041 of the opening and closing blocking piece 104 extends out of the cylinder 4. When the aggregate collecting device 2 moves downward, the opening door part 203 presses down the working part 1041 of the opening and closing blocking piece 104 and presses down along the inclined surface, so that the blocking door 1 can be rotated around the second rotating shaft 101, the opening and closing of the blocking door 1 is realized, and the discharge into the hopper 201 is started.

[0039] Each guide rail 3 is provided with one aggregate collecting device 2, and the guide rails 3 cooperating with the same hopper 201 are composed of four vertical columns with sliding grooves and are arranged in pairs on the axis of symmetry of the tower-type processing device. Four groups of tracks are uniformly and symmetrically arranged on the outer periphery of the cylinder 4 and are arranged along the height direction of the cylinder 4. Therefore, in this embodiment, the sliding blocks 202 are arranged on the side surface of the hopper 201, so that the sliding blocks 202 extend into the sliding grooves and guide the movement of the hopper 201 in the height direction of the cylinder 4, thereby driving the hopper 201 to move to each layer of the mixing area.

[0040] At the same time, the blocking door 1 is in close contact with the outer surface of the cylinder 4 when it is closed, and the width of the blocking door 1 is slightly smaller than the distance between the two side vertical columns at the guide rail 3, so that it can be normally opened and closed between the two side vertical columns.

[0041] In this embodiment, the cylinder 4 is provided with a maintenance and discharge platform 5 on the outer periphery of each layer of the mixing area, and two maintenance and discharge platforms 5 are arranged at three equal points in the height of the cylinder 4. The maintenance and discharge platform 5 is arranged closely between the vertical columns on the outer periphery of the cylinder 4, which meets the walking and transportation of maintenance personnel and small equipment, and is disconnected within the range of the guide rail 3. The maintenance and discharge platform 5 can be used as a maintenance passage for the aggregate collecting device 2, the blocking door 1 and the stirring system 6, etc.

[0042] And, the stirring system 6 is arranged in layers with the door 1, and the stirring system 6 is arranged in the cylinder 4 at the bottom of the arranged area and the height of the maintenance discharge platform 5, and the stirring system 6 pushes the fermentation material to the door 1 while stirring and mixing the fermentation material. It should be noted that the stirring components of the stirring system 6 are fixed in the fermentation warehouse body through a support, and the stirring components can be divided into two groups of stirring rotation centers, one of which is a main rotation center to make the stirring components rotate along the circumferential direction of the cylinder 4, and the other is the rotation center of the stirring shaft, and the stirring shaft is connected to the main rotation center in an inclined manner and makes the stirring shaft rotate to accelerate the stirring efficiency. Meanwhile, the inclined stirring shaft is easier to push the perishable garbage to the door 1 when rotating around the main rotation center.

[0043] Please refer to Figures 1-12 When the tower type processing device passes through the feeding and discharging system, the specific content is as follows:

[0044] After the door 1, the guide rail 3, the collecting device 2 and the stirring system 6 are assembled on the cylinder 4, the two sides of the door 1 are attached to the outer periphery of the cylinder 4, when the collecting device 2 slides from top to bottom along the guide rail 3, when sliding to the top of the door 1 to be opened, the stirring system 6 rotates to the position of the door 1, and the stirring system 6 pushes the material to the door 1 while stirring and mixing the material, the material pushes or the motor drives the first rotating shaft 103 to rotate, so that the opening and closing door piece 104 rotates to the inclined surface part 1042 attached to the top inclined chute 1021, the long edge surface of the opening and closing door piece 104 extends out of the cylinder 4, and the long edge surface of the opening and closing door piece 104 is on the same inclined surface with the inside top working part 1041 of the door plate 102, the long edge surface of the opening and closing door piece 203 is pressed down by the opening door part 203 of the collecting device 2, and is pressed down along the working part 1041, the door 1 rotates around the second rotating shaft 101, and the door 1 is opened. The fermentation material is pushed by the stirring system 6 into the hopper 201 of the collecting device 2, after the hopper 201 is filled, the stirring system 6 rotates away from the door 1, the collecting device 2 slides upward along the guide rail 3, the opening and closing door piece 104 returns to the original position, and the door 1 returns to the original position under the action of the spring at the second rotating shaft 101. Thus, the staggered discharge of layered material and the mixed feeding can be realized, the mixed feeding is that the material discharged through the mixed layer enters the fermentation warehouse body together with fresh material from the feeding port, through the continuous cycle of discharging and feeding procedures, the material in the fermentation warehouse body inside the cylinder 4 is fully mixed, a biological drying reactor with high-temperature fermentation bacteria as the dominant bacteria group is formed, the fermentation efficiency and processing progress of the perishable garbage are effectively improved, and the rapid drying and harmless treatment of the perishable garbage are realized.
