Description

Technical Field

[0001] The utility model relates to the technical field of bio-drying treatment of perishable garbage, in particular to a novel bio-drying feeding and discharging system for perishable garbage. Background Art

[0002] With the acceleration of urbanization, the problem of domestic waste disposal has become increasingly prominent. Among them, perishable waste, which accounts for the largest proportion of domestic waste by weight, has great difficulties in waste disposal due to its high moisture content and easy decay and deterioration. Traditional methods for perishable waste disposal mainly include landfill and incineration. However, landfilling is prone to soil and groundwater pollution, while incineration may produce toxic and harmful gases, causing secondary pollution to the environment. Therefore, finding a new and environmentally friendly method for perishable waste disposal has become an urgent need.

[0003] Bio-drying is a method that uses the action of microorganisms to quickly remove moisture through the heat of biological fermentation. It has a small demand for external heat energy supplement and has a very outstanding reduction effect. Compared with traditional treatment methods, bio-drying has the advantages of environmental protection, energy saving, and resource utilization. It is an effective way to solve the problem of perishable waste disposal and reasonably allocate existing facility resources in the eastern coastal areas of my country where incineration is the main method. However, the existing bio-drying technology still has some problems in treating perishable waste. At present, the biological drying systems for perishable garbage are mainly drum-type and tower-type treatment systems. A large-scale stirring system is generally set in the middle to achieve sufficient mixing through frequent stirring, assisted by forced ventilation and oxygen supply. Compared with the traditional strip-pile treatment process, it is more efficient. However, the drum-type treatment system is relatively limited in treatment scale due to the manufacturing cost and difficulty of the drum structure. The main body of the tower treatment system can adopt reinforced concrete structure, which has low construction cost and adjustable scale and stronger adaptability. Although it can meet the current treatment needs of huge amounts of perishable garbage, the existing tower-type biological drying treatment system has low overall efficiency and cannot meet the needs of rapid drying of perishable garbage. It does not yet have the conditions for expanding and promoting the treatment scale, which leads to the limitations of the existing biological drying system for perishable garbage.

DETAILED DESCRIPTION

[0030] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0031] like Figure 1-12 As shown, a novel bio-drying feeding and discharging system for perishable garbage is provided, wherein a fermentation bin is arranged inside a barrel 4 of an outer shell of a tower treatment device, wherein the bottom surface of the barrel 4 is round and long-cylindrical; a stirring system 6 is arranged inside the fermentation bin, and a layered mixing zone is arranged inside the fermentation bin of the barrel 4, and the mixing zone is divided into three equal parts in the height direction of the barrel 4; the mixing zones of each layer are interconnected, and the stirring system 6 is provided with stirring components in each mixing zone, and the barrel 4 is provided with a groove on each mixing zone. A baffle 1 that can be opened and closed is arranged in the groove part, a guide rail 3 is arranged outside the cylinder 4, and a collecting device 2 that can be moved to the mixing area of ​​each layer and the feed port by lifting or moving down is arranged on the guide rail 3; the collecting device 2 includes a hopper 201, an opening is arranged on the side of the hopper 201 opposite to the cylinder 4, and a door opening part 203 is arranged at the bottom of the hopper 201, and the baffle 1 is provided with a movable opening and closing stopper 104 on the top of its door plate 102, and the opening and closing stopper 104 forms a closed state of the groove part together with the door plate 102 (such as Figure 7 ) or in an open state in contact with the door opening portion 203 (as shown in the figure on the left side of the figure ... Figure 7 (as shown in the figure on the right in the figure).

[0032] In this embodiment, the opening and closing member 104 cooperates with the material collecting device 2 by flipping and opening. A first rotating shaft 103 is fixedly arranged on the opening and closing member 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 driving device for rotating it. The driving device can be an active steering drive by a motor connected to the first rotating shaft 103, or a passive steering drive can be performed by installing a spring on the first rotating shaft 103 or other methods.

[0033] In this embodiment, the opening and closing stopper 104 is a typical non-isosceles triangular shaped surface with a cross-section, the bottom plate is a smooth curve, the two long sides are located on the inside, and the short sides are located on the outside. The opening and closing stopper 104 is provided with an inclined portion 1042 on the side away from the cylinder 4, and the inclined portion 1042 formed by the short side can be fitted with the inclined surface of the top inclined groove 1021.

[0034] Specifically, the opening and closing gear 104 is provided with a working part 1041 on the side opposite to the cylinder 4, and the length of the working part 1041 is greater than the distance between the outer side surface of the door panel 102 and the first rotating shaft 103. Therefore, when the opening and closing gear 104 is flipped to the open state waiting to cooperate with the door opening part 203, the working part 1041 extends out of the cylinder 4.

[0035] The outer surface of the door panel 102 is fitted with the outer periphery of the cylinder 4, and a guide block 1023 is protruding from the inner side of the door panel 102. A first track guide portion 1024 and a second track guide portion 1025 are respectively provided on both sides of the guide block 1023, which can abut against the door opening portion 203. The first track guide portion 1024 and the second track guide portion 1025 are smoothly transitioned and connected. In addition, the first track guide portion 1024 is preferably a beveled surface so that the first track guide portion 1024 can be flush with the operating portion 1041 on the opening and closing gear 104 after opening, such as Figure 7 The second track guide portion 1025 is preferably a smooth curved surface so that the door opening portion 203 moves more smoothly when the hopper 201 moves downward. At the same time, a pushing device can also be provided in the hopper 201 to facilitate the material output.

[0036] Among them, the opening and closing stopper 104 is rotatably connected to the top of the door panel 102 through the first rotating shaft 103. The opening and closing stopper 104 can rotate outward around the first rotating shaft 103 until the inclined portion 1042 is in contact with the top inclined groove 1021. At this time, the operating portion 1041 and the first track guide portion 1024 on the upper inner side of the door panel 102 are on the same plane, so that it is more convenient to drive the door panel 102 to open while the hopper 201 moves downward.

[0037] In this embodiment, a second rotating shaft 101 is provided at the bottom of the door panel 102 and is rotatably connected to the inner wall of the groove, and a bottom inclined groove 1022 is provided on the outer side of the bottom of the door panel 102; the second rotating shaft 101 is cylindrical and fixed at the middle position of the lower part of the door panel 102, connected to the bottom inclined groove 1022, and can be assembled in the preset groove of the outer wall of the cylinder 4. A reset structure is provided on the second rotating shaft 101, and the reset structure can be a reset spring provided at the second rotating shaft 101, so that the stopper 1 can be opened and closed by the reset spring on the second rotating shaft 101 after being separated from the hopper 201, until the door panel 102 is reset to fit with the cylinder 4.

[0038] In this embodiment, the hopper 201 is bucket-shaped, and multiple rows of sliders 202 are symmetrically arranged on the left and right outer surfaces. The arrangement of the sliders 202 corresponds to the slide grooves of the guide rail 3, that is, the collecting device 2 is assembled with the guide rail 3 through the sliders 202 and slides up and down along the guide rail 3. Among them, the door opening part 203 is wedge-shaped as a whole, and the door opening part 203 is arranged at the edge of the hopper 201 opposite to the cylinder 4 side. The outer side surface of the door opening part 203 is flush with the end surface of the hopper 201, and the inner side is a concave arc shape. When the opening and closing block 104 on the top of the baffle 1 is rotated to fit with the top inclined groove 1021, the operating part 1041 of the opening and closing block 104 extends out of the cylinder 4. When the collecting device 2 moves downward, the door opening part 203 presses down the operating part 1041 of the opening and closing block 104, and presses down along the inclined surface, so that the baffle 1 can rotate around the second rotating shaft 101, realize the opening of the baffle 1, and start discharging materials into the hopper 201.

[0039] Among them, each guide rail 3 is equipped with a material collecting device 2, and the guide rail 3 matched with the same hopper 201 is composed of four columns with slide grooves, which are arranged in pairs on the symmetric axis of the tower processing device, and four groups of tracks are evenly and symmetrically arranged on the outer periphery of the cylinder 4, and arranged along the height direction of the cylinder 4. Therefore, in this embodiment, by arranging a slider 202 on the side of the hopper 201, the slider 202 extends into the slide groove and cooperates with the guide rail 3 to drive the hopper 201 to rise and fall in the height direction of the cylinder 4, thereby driving the hopper 201 to move to the mixing area of ​​each layer.

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

[0041] In this embodiment, the outer periphery of each mixing zone of the cylinder 4 is provided with an inspection and discharging platform 5, and two inspection and discharging platforms 5 are arranged at three equal points in the height of the cylinder 4. The inspection and discharging platforms 5 are arranged closely between the outer periphery columns of the cylinder 4 to meet the walking and transportation requirements of the maintenance personnel and the small equipment, and are disconnected within the range of the guide rail 3. The inspection and discharging platform 5 can be used as an inspection and maintenance channel for the collection device 2, the baffle door 1 and the mixing system 6.

[0042] Moreover, the stirring system 6 is arranged in layers like the gate 1. The stirring system 6 is arranged in the bottom surface of the arranged area and in the cylinder 4 at the height of the inspection and discharge platform 5. The stirring system 6 pushes the fermented materials toward the gate 1 while stirring and mixing the fermented materials. It should also be noted that the stirring components of the stirring system 6 are fixed in the fermentation bin by a bracket. The stirring components can be divided into two groups of stirring rotation centers, one of which is the main body rotation center, so that the stirring components rotate along the circumferential direction of the cylinder 4, and the other is the rotation center of the stirring shaft. The stirring shaft is obliquely connected to the main body rotation center and the stirring shaft is rotated to accelerate the stirring efficiency. At the same time, the oblique stirring shaft is more likely to push the perishable garbage toward the gate 1 when rotating around the main body rotation center.

[0043] See also Figure 1-12 When the tower processing device passes through the feeding and discharging system, the specific contents are as follows:

[0044] After the baffle door 1, the guide rail 3, the material collecting device 2 and the stirring system 6 are assembled on the cylinder 4, the two sides of the baffle door 1 are fitted with the outer periphery of the cylinder 4, and when the material collecting device 2 slides from top to bottom along the guide rail 3, when it slides to the top of the baffle door 1 to be opened, the stirring system 6 rotates to the position of the baffle door 1, and the stirring system 6 pushes the material to move toward the baffle door 1 while stirring the mixed material, and the material pushes or the motor drives the first rotating shaft 103 to rotate, so that the opening and closing stopper 104 rotates to the inclined portion 1042 and fits with the top inclined groove 1021, and the long side of the opening and closing stopper 104 extends out of the cylinder 4, and the long side of the opening and closing stopper 104 is on the same inclined surface as the top working portion 1041 on the inner side of the door panel 102, and the long side of the opening and closing stopper 203 is pressed down on the door opening portion 203 of the material collecting device 2, and is pressed down along the working portion 1041, and the baffle door 1 rotates around the second rotating shaft 101 to realize the opening of the baffle door 1. The fermented material is pushed into the hopper 201 of the collecting device 2 by the stirring system 6. After the hopper 201 is filled, the stirring system 6 rotates away from the baffle 1, the collecting device 2 slides upward along the guide rail 3, the opening and closing stopper 104 returns, and the baffle 1 returns under the action of the spring at the second rotating shaft 101. In this way, the staggered discharge and mixed feeding of the layered materials can be realized. The mixed feeding is the material discharged through the mixed layer and then enters the fermentation bin from the feed port together with the fresh material. Through the continuous cycle of the discharge and feeding procedures, the materials in the fermentation bin inside the cylinder 4 are fully mixed, forming a biological drying reactor with high-temperature fermentation bacteria as the dominant flora, effectively improving the fermentation efficiency and treatment progress of perishable garbage, and realizing the rapid drying and harmless treatment of perishable garbage.

[0045] The above embodiment is only a preferred technical solution of the present invention. Those skilled in the art should understand that the technical solutions or parameters in the embodiments can be modified or replaced without departing from the principle and essence of the present invention, and all should be included in the protection scope of the present invention.
