Description
Technical Field
[0001] This invention relates to the field of smart energy technology, specifically to a distributed energy supply system for industrial parks. Background Technology
[0002] Integrated energy systems (IES) refer to a comprehensive energy system formed through the organic coordination and optimization of various energy generation, transmission and distribution, conversion, storage, and consumption processes during planning, design, construction, and operation. Distributed energy, as a new sustainable energy supply method, offers advantages over traditional centralized energy supply methods, including proximity to users, lower energy transmission losses, and higher energy utilization efficiency. It represents a crucial direction for national energy transformation. Distributed energy zones typically encompass multiple energy sources. For example, patent number 201811347150.4 mentions that distributed energy generally includes battery storage, photovoltaic systems, natural gas cogeneration systems, biomass gas cogeneration systems, biomass gasifiers, steam storage tanks, and biomass boilers. Biomass gasifiers, as a type of distributed energy, are used in industrial parks... While widely used in daily life, the equipment that generates this type of energy still has some problems. For example, patent number CN202111459251.2 discloses a technical solution that can treat waste generated from combustion. However, this technical solution still has some problems. In this solution, the combustible material is burned in the combustion chamber and discharged through a perforated plate. However, during the discharge process, relying solely on the perforated plate to discharge the combustible material may result in the perforated plate having large holes, causing incomplete combustion and direct drop, leading to heat loss. If the perforated plate has small holes, the waste formed after combustion cannot be fully discharged from the perforated plate, leading to blockage of the perforated plate, thus affecting the use of the equipment and reducing its practicality and processing efficiency.
[0003] Based on this, the present invention designs a distributed energy supply system for industrial parks to solve the above problems. Summary of the Invention
[0004] The purpose of this invention is to provide a distributed energy supply system for industrial parks to solve the problems mentioned in the background art, such as incomplete combustion of materials during equipment combustion, or insufficient discharge of combustibles due to small apertures after combustion.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a distributed energy supply system for industrial parks, comprising a combustion chamber, a shell installed on one side of the combustion chamber, a discharge chamber fixedly connected to the bottom surface of the combustion chamber, a processing chamber installed on the bottom surface of the discharge chamber, a stirring mechanism disposed within the shell, and a closing mechanism disposed on the front side of the shell and electrically connected to the stirring mechanism. Two perforated plates are installed in the discharge chamber, and a closing plate is slidably connected between the two perforated plates. A transmission mechanism is provided between the closing plate and the closing mechanism. A driving mechanism is provided on the bottom surface of the closing plate. A cleaning mechanism is installed on the closing plate. A dust suppression mechanism is provided on the discharge chamber. A pressing mechanism is installed in the processing chamber.
[0006] As a further embodiment of the present invention, the stirring mechanism includes a first hydraulic rod, a fixed frame, a rotating shaft, paddles, a first gear, and a first rack. The first hydraulic rod is mounted on the outer casing, and a fixed frame is mounted on one end of the first hydraulic rod. A rotating shaft is rotatably connected inside the fixed frame, and multiple paddles are provided on the rotating shaft. The paddles are L-shaped. First gears are mounted on both ends of the rotating shaft, and first racks are mounted on both sides of the inner wall of the combustion chamber. The first gears and first racks mesh with each other.
[0007] As a further embodiment of the present invention, the closing mechanism includes a closing door, a second rack, and a contact switch. The closing door is slidably connected to the outer casing. The stirring mechanism is located on one side of the closing door. Two second racks are installed on the closing door. A contact switch is provided on the upper side of the closing door. The contact switch is electrically connected to the first hydraulic rod in the stirring mechanism.
[0008] As a further embodiment of the present invention, the transmission mechanism includes a third rack and a linkage assembly. The third rack is installed on both sides of the sealing plate, and the linkage assembly is provided on both sides of the combustion chamber. The third rack and the linkage assembly mesh with each other, and the linkage assembly and the second rack mesh with each other.
[0009] As a further embodiment of the present invention, the driving mechanism includes a drive motor, a second gear and a fourth rack. The drive motor is installed on the discharge chamber, the second gear is installed at the output end of the drive motor, and the fourth rack is fixedly connected to the bottom surface of the closed plate. The second gear and the fourth rack mesh with each other.
[0010] As a further embodiment of the present invention, the cleaning mechanism is located between two drain plates. The cleaning mechanism includes a fixed plate, springs, and a cleaning plate. The fixed plate is fixedly connected to the sealing plate. Two springs are fixedly connected to the bottom surface of the fixed plate. The cleaning plate is fixedly connected between the two springs. The cleaning plate and the drain plates are movably connected.
[0011] As a further embodiment of the present invention, the dust suppression mechanism includes a water storage tank, a pump, and nozzles. The water storage tank is installed on the discharge chamber, the pump is installed on the water storage tank, and two nozzles are installed on the discharge chamber. A conveying pipe is provided between the nozzles and the pump, and the nozzles are located below the sluice plate.
[0012] As a further embodiment of the present invention, the pressing mechanism includes a second hydraulic rod, a push plate, and a pressure plate. Two second hydraulic rods are installed on the processing chamber, one of which is vertically arranged and the other is horizontally placed. One end of the second hydraulic rod is equipped with a push plate, and the other end of the second hydraulic rod is equipped with a pressure plate. A door is provided on one side of the processing chamber.
[0013] This invention creates a sealed combustion chamber by placing a sealing plate between two perforated plates. This prevents the combustion material from falling out before it is fully burned due to large perforations on the perforated plates, thus avoiding heat loss. When the sealing plate is opened, the stirring mechanism works simultaneously to agitate the waste material after combustion, preventing residue from clumping and ensuring complete discharge. This also avoids the problem of the perforated plates not being able to discharge the waste material properly due to small perforations, further ensuring the efficiency of the equipment during discharge and preventing waste accumulation. Meanwhile, when materials are discharged, the dust suppression mechanism suppresses dust in the waste generated after combustion, ensuring the waste contains a certain amount of moisture to prevent splashing during discharge and thus environmental pollution. When the waste contains a certain amount of moisture, the pressing mechanism presses the moisture-containing waste into blocks, which are then uniformly removed and processed. This avoids the need to release the combustibles into the air during processing, thus preventing air pollution. After the waste is lumped together, it can be uniformly landfilled or the soil texture can be altered, thus enabling the secondary utilization of waste and further improving the practicality and convenience of the equipment.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0023] Please see Figures 1-5The present invention provides a technical solution: a preferred embodiment of a distributed energy supply system for an industrial park includes a combustion chamber 1, an outer shell 2 installed on one side of the combustion chamber 1, a discharge chamber 3 fixedly connected to the bottom surface of the combustion chamber 1, a processing chamber 4 installed on the bottom surface of the discharge chamber 3, a stirring mechanism 5 provided inside the outer shell 2, a closing mechanism 12 provided on the front side of the outer shell 2, the closing mechanism 12 and the stirring mechanism 5 electrically connected, two slugging plates 16 installed inside the discharge chamber 3, a closing plate 17 slidably connected between the two slugging plates 16, a transmission mechanism 18 provided between the closing plate 17 and the closing mechanism 12, a driving mechanism 21 provided on the bottom surface of the closing plate 17, a cleaning mechanism 25 installed on the closing plate 17, a dust suppression mechanism 29 provided on the discharge chamber 3, and a pressing mechanism 33 installed inside the processing chamber 4.
[0024] During operation, fuel is placed in combustion chamber 1 for combustion. At this time, the closing mechanism 12 is closed, and the sealing plate 17 is located between the two perforated plates 16, making combustion chamber 1 an independent and sealed combustion space. As combustion occurs in combustion chamber 1, when the fuel combustion is complete, the control drive mechanism 21 moves the sealing plate 17, creating a connection between the two perforated plates 16. The burned material in combustion chamber 1 is discharged through the perforated plates 16. When the sealing plate 17 opens, the closing mechanism 12 opens simultaneously. As the closing mechanism 12 opens, the contact switch 15 in the closing mechanism 12 is energized, and the components in the stirring mechanism 5 operate, stirring the burned material. The material is then quickly discharged through the perforated plates 16. During the material discharge process, the dust suppression mechanism 29 extracts the liquid and sprinkles it on the falling burning material. At this time, the burning material condenses upon contact with water and has a certain degree of humidity. Then, the pressing mechanism 33 pushes the humid burning material to form a block and removes it. The equipment completes its work and then closes the sealing plate 17 again. During the closing process of the sealing plate 17, the cleaning mechanism 25 cleans the leak plate 16 to prevent the leak plate 16 from being blocked again.
[0025] This invention utilizes a sealing plate 17 positioned between two perforated plates 16 to create a sealed combustion chamber 1 during combustion. This prevents the combustion material from falling out before it is fully burned due to larger perforations on the perforated plates 16, thus avoiding heat loss. When the sealing plate 17 is opened, the stirring mechanism 5 works simultaneously to agitate the waste material after combustion, preventing clumping and ensuring complete discharge. This also avoids the perforated plates 16 from being unable to fully discharge the waste material due to smaller perforations, further ensuring the efficiency of the equipment during discharge and preventing waste accumulation.
[0026] When materials are discharged, the dust suppression mechanism 29 suppresses dust in the waste generated after combustion, ensuring the waste contains a certain amount of moisture to prevent splashing during discharge and thus environmental pollution. When the waste contains a certain amount of moisture, it accumulates in the processing chamber 4. At this time, the pressing mechanism 33 presses the moisture-containing waste into blocks, forming a block. The blocks are then removed and processed uniformly, thus preventing the combustion materials from being discharged into the air during processing and causing air pollution. After the combustion waste is agglomerated, it can be uniformly landfilled or the soil texture can be changed, thus enabling the secondary utilization of waste and further improving the practicality and convenience of the equipment.
[0027] As a further embodiment of the present invention, the stirring mechanism 5 includes a first hydraulic rod 6, a fixed frame 7, a rotating shaft 8, paddles 9, a first gear 10, and a first rack 11. The first hydraulic rod 6 is mounted on the outer casing 2, and a fixed frame 7 is mounted on one end of the first hydraulic rod 6. The rotating shaft 8 is rotatably connected inside the fixed frame 7. Multiple paddles 9 are provided on the rotating shaft 8, and the paddles 9 are L-shaped. The first gears 10 are mounted on both ends of the rotating shaft 8, and the first racks 11 are mounted on both sides of the inner wall of the combustion chamber 1. The first gears 10 and the first racks 11 mesh with each other.
[0028] When the sealing plate 17 is opened, the sealing plate 17 also opens in conjunction with the closing mechanism 12. At this time, the contact switch 15 controls the first hydraulic rod 6 to work, so that the first hydraulic rod 6 is energized. Then the first hydraulic rod 6 extends, causing the fixed frame 7 to move. When the fixed frame 7 moves to a certain position, the first gear 10 and the second rack 14 on both sides of the rotating shaft 8 mesh. Then the first gear 10 rotates under the drive of the first rack 11, thereby causing the rotating shaft 8 to rotate. When the rotating shaft 8 rotates, the paddle 9 installed on the rotating shaft 8 agitates the waste formed after combustion, so that the clumped combustion waste can be quickly discharged through the sluice plate 16, thereby avoiding the slowdown of equipment discharge efficiency due to waste clumping, and further improving the cleaning efficiency of the equipment.
[0029] The closing mechanism 12 includes a closing door 13, a second rack 14, and a contact switch 15. The closing door 13 is slidably connected to the outer casing 2. The stirring mechanism 5 is located on one side of the closing door 13. Two second racks 14 are installed on the closing door 13. The contact switch 15 is provided on the upper side of the closing door 13. The contact switch 15 is electrically connected to the first hydraulic rod 6 in the stirring mechanism 5.
[0030] The working principle of the closing mechanism 12 is briefly described as follows: When the sealing plate 17 is opened, the transmission mechanism 18 drives the closing mechanism 12 to work. At this time, the second rack 14 is driven by the transmission mechanism 18 to move upward. As the second rack 14 moves upward, it drives the closing door 13 to move upward, thereby connecting the outer shell 2 and the combustion chamber 1. When the closing door 13 moves to a suitable position, the contact switch 15 is energized. At this time, the stirring mechanism 5 starts to work. The closing mechanism 12 can effectively separate the stirring mechanism 5 and the combustion chamber 1, thereby preventing damage to the stirring mechanism 5 during combustion in the combustion chamber 1, thus further ensuring the safety of the stirring mechanism 5 and preventing heat leakage during equipment use.
[0031] As a further embodiment of the present invention, the transmission mechanism 18 includes a third rack 19 and a linkage assembly 20. Third racks 19 are installed on both sides of the sealing plate 17, and linkage assemblies 20 are provided on both sides of the combustion chamber 1. The third racks 19 and linkage assemblies 20 mesh with each other, and the linkage assembly 20 meshes with the second rack 14. When the sealing plate 17 is opened, the sealing plate 17 drives the third rack 19 to move. At this time, the third rack 19 drives the gear in the linkage assembly 20 to rotate. When the gear in the linkage assembly 20 rotates, other parts in the linkage assembly 20 work, thereby causing the linkage assembly 20 to drive the second rack 14 on the sealing door to move, thus opening the sealing door. When the sealing plate 17 in the equipment is open, the sealing plate 17, in conjunction with the transmission mechanism 18, opens the closing mechanism 12, thereby ensuring the convenience of the equipment during use. When the sealing plate 17 is open, the equipment is in a discharge state, making the equipment more convenient and faster to operate.
[0032] The drive mechanism 21 includes a drive motor 22, a second gear 23 and a fourth rack 24. The drive motor 22 is installed on the discharge chamber 3. The second gear 23 is installed at the output end of the drive motor 22. The fourth rack 24 is fixedly connected to the bottom surface of the closed plate 17. The second gear 23 and the fourth rack 24 mesh with each other.
[0033] When in operation, the drive motor 22 is turned on, causing the drive motor 22 to drive the second gear 23 to rotate. When the second gear 23 rotates, it drives the fourth rack 24 to rotate. At this time, the fourth rack 24 drives the closing plate 17 to move, thereby effectively ensuring the opening and closing of the closing plate 17, and thus ensuring the operation of the equipment. The drive mechanism 21 provides a certain amount of power to the equipment, making the equipment more labor-saving and convenient to operate.
[0034] As a further embodiment of the present invention, the cleaning mechanism 25 is located between two drain plates 16. The cleaning mechanism 25 includes a fixed plate 26, springs 27 and a cleaning plate 28. The fixed plate 26 is fixedly connected to the closed plate 17. Two springs 27 are fixedly connected to the bottom surface of the fixed plate 26. The cleaning plate 28 is fixedly connected between the two springs 27. The cleaning plate 28 and the drain plate 16 are movably connected.
[0035] The above-described structure design allows the waste material formed after combustion to leak out through the sluice plate 16 when the equipment is discharging. When the closing plate is closed, the cleaning mechanism 25 is located near the inner wall of the discharge chamber 3. When the closing plate is opened, it drives the cleaning plate 28 to move. At this time, the cleaning plate 28, in conjunction with the elastic force of the spring 27, is tightly attached to one side of the sluice plate 16. As the closing plate moves, the cleaning plate 28 can effectively clean one side of the sluice plate 16, thereby preventing dust from clogging the holes in the sluice plate 16 and affecting the secondary operation of the sluice plate 16. This further ensures the discharge efficiency of the equipment and prevents the sluice plate 16 from becoming clogged during the discharge process, thus affecting the use of the equipment. When the closing plate 17 is closed, the cleaning mechanism 25 can also clean the sluice plate 16, further improving the practicality of the equipment.
[0036] The dust suppression mechanism 29 includes a water storage tank 30, a pump 31, and nozzles 32. The water storage tank 30 is installed on the discharge chamber 3, and the pump 31 is installed on the water storage tank 30. Two nozzles 32 are installed on the discharge chamber 3, and a conveying pipe is provided between the nozzles 32 and the pump 31. The nozzles 32 are located below the baffle plate 16. During material discharge, the pump 31 is turned on to extract liquid from the water storage tank 30 and deliver the liquid to the nozzles 32. The nozzles 32 then spray the liquid onto the falling waste material, causing the waste material to absorb the water mist and become moist, preventing dust from splashing during the fall. When the dust absorbs a large amount of liquid, it will not splash, thus preventing dust pollution during processing and further improving the practicality of the equipment.
[0037] As a further embodiment of the present invention, the pressing mechanism 33 includes a second hydraulic rod 34, a push plate 35, and a pressure plate 36. Two second hydraulic rods 34 are installed on the processing chamber 4, one of which is vertically arranged and the other is horizontally placed. One end of the second hydraulic rod 34 is equipped with the push plate 35, and the other end of the second hydraulic rod 34 is equipped with the pressure plate 36. A door is provided on one side of the processing chamber 4. When the material enters the processing chamber 4, one of the second hydraulic rods 34 is controlled to push the push plate 35 to move. When the push plate 35 pushes the material to the underside of the pressure plate 36, the other second hydraulic rod 34 is controlled to descend, so that the second hydraulic rod 34 drives the pressure plate 36 to press the wet material into blocks. Then, the push plate 35 and the pressure plate 36 cooperate to press the material into blocks. After the material is pressed into blocks, the processing chamber 4 can be opened to uniformly process the pressed material, thereby reusing waste and avoiding dust pollution of the environment, further improving the practicality and convenience of the equipment.
