Description

Technical Field

[0001] This application relates to the field of waste liquid treatment equipment technology, and in particular to a novel waste liquid furnace ash discharge device. Background Technology

[0002] The ash discharge device is a key auxiliary device for combustion equipment such as waste liquid furnaces. It promptly and continuously discharges the ash produced after fuel combustion from the bottom of the furnace or the gaps between the grate, preventing ash accumulation from affecting furnace ventilation, heat transfer efficiency, and combustion stability. When the waste liquid furnace is running, the waste liquid is atomized through nozzles and sent into the furnace, where it is combusted and decomposed at high temperatures. The ash produced during combustion settles to the grate or the bottom of the furnace. At this time, the ash discharge device is activated, scraping or pushing the ash off the grate to the ash discharge channel. After the discharge rate is controlled by a gate valve, the ash is transported to the ash storage silo for temporary storage.

[0003] A search revealed Chinese patent publication number CN2524098Y, which discloses a heat pipe type organic waste liquid processor. This processor integrates a combustion furnace and a concentration device into one unit. The combustion furnace's combustion chamber's cold water section, the inner top and surrounding walls of the U-shaped fly ash settling chamber, and the heating surfaces of the water-cooled partition walls all utilize heat pipe water-cooling structures. The concentration device is divided into two circulation loops: one loop consists of heater I, separator I, circulation pump I, and a balance tank; the other loop consists of heater II, separator II, circulation pump II, and a balance tank. The top of the heat pipe in the heat pipe water-cooling structure is connected to the heater, and the bottom of the heat pipe is connected to the heater's return water pipe. The entire heat pipe type organic waste liquid processor is supported on a frame. Its key feature is that it utilizes the heat released from the concentrated waste liquid during combustion to directly concentrate the waste liquid discharged during alcohol production. The concentrated waste liquid is then returned to the furnace for combustion, which is easily controlled, less prone to coking and ash accumulation, saves energy, requires less equipment investment, and reduces waste liquid treatment costs.

[0004] The aforementioned patent specification mentions "using the heat released from the combustion of waste liquid concentrate to directly concentrate the waste liquid discharged from alcohol production, and the waste liquid concentrate is then returned to the furnace for combustion, which is easy to control, does not easily coke or accumulate ash, saves energy, requires less equipment investment, and reduces waste liquid treatment costs." While the above content does allow the waste liquid concentrate to be returned to the furnace for combustion, and the combustion is easy to control, does not easily coke or accumulate ash, saves energy, requires less equipment investment, and reduces waste liquid treatment costs, some devices lack sufficient cleaning power. Fine ash residue remains in the gaps between the grate bars for a long time, causing blockages, resulting in ash residue accumulation that affects the normal operation of the grate, and may even cause mechanical jamming failures, limiting the stable operation and efficient processing capacity of the waste liquid furnace. Therefore, a new type of waste liquid furnace ash discharge device is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this application is to provide a new type of waste liquid furnace ash discharge device, which aims to improve the problem of furnace grate operation failure caused by ash accumulation during ash discharge in some furnace ash discharge devices.

[0006] The novel waste liquid furnace ash discharge device provided in this application adopts the following technical solution:

[0007] A novel waste liquid furnace ash discharge device includes a shell, a pushing mechanism on the outside of the shell, a supporting base plate fixedly connected inside the shell, a dust removal mechanism on the outside of the supporting base plate, a cleaning mechanism inside the shell, two air inlets on both sides inside the shell, a slag scraping mechanism inside the shell, a dust guide plate fixedly connected to the outside of the shell, and a limiting frame fixedly connected to both sides inside the shell. Hydraulic cylinders are rotatably connected to both sides inside the shell, a transmission block is fixedly connected to the driving end of each hydraulic cylinder, a transmission plate is rotatably connected to the outside of the transmission block, a limiting component is provided inside the transmission plate, and a cleaning plate is fixedly connected to the outside of the limiting component.

[0008] Through the above technical solution: the external pushing mechanism, the internal supporting base plate and the dust removal mechanism work together; protective air is introduced through the air inlets on both sides of the shell; in the cleaning mechanism, the limiting frame is fixed on both sides inside the shell; the hydraulic cylinder inside the shell drives the transmission block to extend and retract, driving the transmission plate to rotate; the transmission plate is connected to the cleaning plate through the internal limiting component, so that it reciprocates to clean the grate; the slag scraping mechanism inside the shell transports waste slag, and the external dust guide plate assists in guiding the slag, so as to achieve efficient ash removal and stable conveying, reduce ash and slag accumulation and blockage, and ensure the reliability of system operation.

[0009] Preferably, the pushing mechanism includes a hydraulic cylinder, the hydraulic cylinder is fixedly connected to the outside of the housing, the driving end of the hydraulic cylinder is fixedly connected to a transmission plate two, and the transmission plate two is fixedly connected to a connecting plate two.

[0010] By adopting the above technical solution, in the external pushing mechanism of the outer shell, the oil cylinder drives the transmission plate two to reciprocate. The transmission plate two transmits power through the externally fixed connecting plate two, driving the grate to slide and push the waste slag along the inside of the outer shell, realizing the stable conveying of waste slag to the slag discharge end, reducing the slag jamming failure rate during the slag discharge process, and improving the reliability of system operation.

[0011] Preferably, the limiting component includes a connecting post, the connecting post is fixedly connected to the inside of the air inlet, and arc-shaped limiting grooves are provided on both sides of the outer side of the limiting frame;

[0012] By adopting the above technical solution, in the limiting component, the connecting column is fixed inside the air inlet to provide support, and the arc-shaped limiting grooves on both sides of the limiting frame constrain the movement trajectory of the transmission plate. When the hydraulic cylinder drives the transmission block to move the transmission plate, the transmission plate slides along the arc-shaped limiting groove, and the connecting column drives the cleaning plate to clean stably, ensuring the cleaning trajectory, avoiding the accumulation of ash and slag, and improving the cleaning efficiency and equipment operation stability.

[0013] Preferably, the outer part of the arc-shaped limiting groove is slidably connected to the inside of the arc-shaped limiting groove, and the outer part of the transmission plate is slidably connected to the outside of the limiting frame;

[0014] By adopting the above technical solution, the transmission plate is externally slidably connected to the outside of the limiting frame, and its corresponding position slides along the inside of the arc-shaped limiting groove on both sides of the limiting frame. When the hydraulic cylinder drives the transmission block to move the transmission plate, the arc-shaped limiting groove forms a trajectory constraint on the transmission plate, ensuring that it moves stably along a fixed arc path, thereby driving the cleaning plate to clean the grate gap, avoiding the problem of incomplete cleaning caused by movement deviation, and improving the operational stability of the cleaning mechanism.

[0015] Preferably, a connecting shaft is fixedly connected to the outside of the connecting plate two, a grate is fixedly connected to the outside of the connecting shaft, and the outside of the connecting shaft is slidably connected to the inside of the outer shell;

[0016] By adopting the above technical solution, when the mechanism is running, the connecting shaft fixed to the outside of the connecting plate transmits power to the grate fixed to the outside. The connecting shaft slides along the inside of the shell, driving the grate to move towards the slag discharge end. Through the sliding cooperation of the connecting shaft and the power transmission, the grate can stably push the waste slag. Combined with the stepped grate design, the waste slag is conveyed and initially crushed in stages, reducing the load on subsequent equipment, reducing the risk of slag jamming, and improving the reliability of the slag discharge system.

[0017] Preferably, the dust removal mechanism includes a telescopic rod, a pushing block is provided on the outside of the telescopic rod, the pushing block is slidably connected to the outside of the supporting base plate, and a dust removal port is slidably connected to the outside of the outer shell.

[0018] By adopting the above technical solution, when the dust removal mechanism is running, the telescopic rod drives the external pushing block to slide along the outside of the support base plate, pushing the accumulated ash that falls from the grate gap to the ash cleaning port that is slidably connected to the outside of the shell. The telescopic rod drives the pushing block to clean the accumulated ash and discharge it through the ash cleaning port, avoiding the accumulation of ash and slag that blocks the air chamber and affects the distribution of primary air, preventing the hardening of ash and slag from jamming the transmission components, reducing the ash discharge failure rate, and ensuring the stable operation of the system.

[0019] Preferably, a sliding strip is fixedly connected to the outside of the dust removal port, the sliding strip is slidably connected to the outside of the housing, a limiting block is fixedly connected to the outside of the housing, and the sliding strip is slidably connected to the inside of the limiting block.

[0020] By adopting the above technical solution, the dust removal mechanism ensures stable sliding of the ash removal port through the cooperation of the sliding strip and the limit block, which facilitates manual removal of bottom ash during maintenance shutdowns, avoids ash and slag accumulation that blocks the air chamber, prevents ash and slag from hardening and jamming the transmission components, and reduces the ash discharge failure rate.

[0021] Preferably, the slag scraping mechanism includes a support frame, the support frame is fixedly connected to the outside of the housing, a motor is fixedly connected to the inside of the support frame, a sprocket is fixedly connected to the drive end of the motor, a chain is coupled to the outside of the sprocket, a connecting plate is fixedly connected to the outside of the chain, and a baffle is fixedly connected to the outside of the connecting plate.

[0022] By adopting the above technical solution, in the slag scraping mechanism, the support frame is fixed to the outside of the shell to provide support. The motor drive end inside the support frame drives the sprocket to rotate, and the chain coupled to the sprocket moves accordingly. The connecting plate outside the chain drives the baffle to move synchronously. The baffle transports the waste slag pushed by the grate through the chain transmission. Combined with the gravity crushing of the grate's stepped structure, the mechanical impact of the scraper is reduced, the risk of slag jamming and material jamming is reduced, and the reliability of the slag discharge system is improved.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The transmission block and transmission plate are linked by a hydraulic cylinder. Under the constraint of the limit frame and arc-shaped limit groove, the cleaning plate is driven to achieve stable reciprocating motion. This can clean the ash accumulation on the grate surface and in the gaps, avoiding the problem of ash and slag accumulation and blockage from the source. Fine ash and slag fall naturally into the bottom air chamber through the grate gaps, which reduces the risk of mechanical jamming and prevents the air passage from being blocked and affecting the system operation. At the same time, it effectively avoids the hidden danger of fine ash and slag hardening and jamming the transmission components after long-term retention in the grate gaps, ensuring that the mechanical reciprocating motion of the grate is always smooth, thereby stabilizing the grate heat dissipation effect and combustion efficiency, and significantly improving the operational stability and reliability of the slag removal system.

[0025] 2. The transmission plate two is driven by the hydraulic cylinder to make stable reciprocating motion. Through the linkage between the connecting plate two and the connecting shaft, the grate slides along the inside of the outer shell, providing continuous and controllable mechanical power for pushing the waste residue. During the pushing process, the stepped grate can transport the waste residue from top to bottom step by step. The structural height difference allows large pieces of waste residue to be naturally crushed in the initial stage, effectively reducing the processing load of the subsequent slag discharge machine. It ensures the directionality and stability of the waste residue moving towards the slag discharge end, avoiding the problem of uneven force distribution caused by manual pushing or single drive. In addition, the stepped conveying makes the biomass fuel burn more fully and evenly, improving the combustion efficiency. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0033] Example: A novel waste liquid furnace ash discharge device, referring to... Figure 1 , Figure 3 and Figure 4The system includes an outer casing 1, with a pushing mechanism 8 on its exterior, providing power to push waste residue. A support base plate 7 is fixedly connected inside the outer casing 1, supporting the dust removal mechanism 3 to ensure overall stability. The dust removal mechanism 3 is located outside the support base plate 7, removing accumulated dust from the bottom and preventing blockage of the air chamber. The cleaning mechanism 6 includes a limiting frame 61, fixedly connected to both sides of the interior of the outer casing 1. Hydraulic cylinders 62 are rotatably connected to both sides of the interior of the outer casing 1. A transmission block 63 is fixedly connected to the drive end of the hydraulic cylinder 62. The transmission block 63 is an intermediate component used to transmit power to the hydraulic cylinder 62 and achieve rotational connection. The transmission block 63 is externally rotatably connected to the transmission plate 64. The transmission block 63 is an intermediate component used to transmit power to the hydraulic cylinder 62 and achieve rotational connection. The limiting frame 61 is a fixed frame that provides sliding support and trajectory constraint for the transmission plate 64. The transmission plate 64 is internally provided with a limiting component 66. The limiting component 66 is externally fixedly connected to the cleaning plate 65. The limiting component 66 is a constraint structure used to ensure the stable movement of the cleaning plate 65. The cleaning plate 65 is an execution component used to directly contact the surface and gaps of the grate 83 for cleaning.

[0034] The limiting component 66 includes a connecting post 661, which is a support connector for connecting the air inlet 4 and the cleaning plate 65. The external part of the connecting post 661 is fixedly connected to the inside of the air inlet 4. The outer sides of the limiting frame 61 are provided with arc-shaped limiting grooves 662. The arc-shaped limiting grooves 662 are arc-shaped grooves used to limit the sliding path of the transmission plate 64. The external part of the arc-shaped limiting grooves 662 is slidably connected to the inside of the arc-shaped limiting grooves 662. The external part of the transmission plate 64 is slidably connected to the outside of the limiting frame 61, so as to realize the sliding cooperation between the transmission plate 64 and the limiting frame 61 and ensure the stability of movement.

[0035] Specifically, when the ash removal device is working, the pushing mechanism 8 outside the outer shell 1 provides the power to push the waste residue, and the supporting base plate 7 inside supports the dust removal mechanism 3 to ensure overall stability. In the cleaning mechanism 6, the limiting frame 61 fixed on both sides inside the outer shell 1 provides support and constraint for the transmission. The hydraulic cylinder 62 inside the outer shell 1 drives the transmission block 63 to extend and retract. The transmission block 63 drives the rotatably connected transmission plate 64 to move. The transmission plate 64 slides along the outside of the limiting frame 61 and its corresponding parts slide along the arc-shaped limiting groove 662. The connecting column 661 of the limiting component 66 drives the cleaning plate 65 to reciprocate, cleaning the surface and gaps of the grate 83. The dust removal mechanism 3 simultaneously removes the bottom ash accumulation to avoid blockage of the air chamber. The whole system achieves stable ash removal and waste residue treatment through the coordinated operation of various structures.

[0036] Reference Figure 1 , Figure 2 and Figure 5The driving mechanism 8 includes a hydraulic cylinder 82, which is fixedly connected to the outside of the outer shell 1. A transmission plate 81 is fixedly connected to the driving end of the hydraulic cylinder 82. The hydraulic cylinder 82 is used to drive the transmission plate 81 to reciprocate. A connecting plate 84 is fixedly connected to the outside of the transmission plate 81. The transmission plate 81 transmits the power of the hydraulic cylinder 82 to the connecting plate 84. A connecting shaft 85 is fixedly connected to the outside of the connecting plate 84. The connecting plate 84 connects the transmission plate 81 and the connecting shaft 85 to transmit thrust. A grate 83 is fixedly connected to the outside of the connecting shaft 85. The connecting shaft 85 transmits the power to the grate 83 and guides its sliding direction. The outside of the connecting shaft 85 is slidably connected to the inside of the outer shell 1. The grate 83 carries and pushes the waste residue to achieve stepped conveying and crushing.

[0037] The dust removal mechanism 3 includes a telescopic rod 34, and a push block is provided on the outside of the telescopic rod 34. The telescopic rod 34 is used to drive the push block to move. The push block pushes the bottom dust to the dust removal port 31. The outside of the push block is slidably connected to the outside of the support base plate 7. The outside of the outer shell 1 is slidably connected to the dust removal port 31, which provides a channel for removing dust. The outside of the dust removal port 31 is fixedly connected to a sliding strip 33. The outside of the sliding strip 33 is slidably connected to the outside of the outer shell 1. The outside of the outer shell 1 is fixedly connected to a limiting block 32. The sliding strip 33 guides the dust removal port 31 to open and close. The outside of the sliding strip 33 is slidably connected to the inside of the limiting block 32. The limiting block 32 restricts the movement trajectory of the sliding strip 33 to ensure that the dust removal port 31 is aligned.

[0038] The slag scraping mechanism 5 includes a support frame 51, which is externally fixedly connected to the outside of the housing 1. A motor 56 is fixedly connected inside the support frame 51. The support frame 51 is a mounting frame for fixing the motor 56 and the sprocket 52. The drive end of the motor 56 is fixedly connected to the sprocket 52, which drives the sprocket 52 to rotate. A chain 53 is externally coupled to the sprocket 52. A connecting plate 54 is fixedly connected to the outside of the chain 53. A baffle 55 is fixedly connected to the outside of the connecting plate 54. The chain 53 transmits power and drives the baffle 55 to move. The connecting plate 54 connects the chain 53 and the baffle 55. The baffle 55 is used to push the waste slag to move along the transport path.

[0039] Specifically, in the driving mechanism 8, the hydraulic cylinder 82 outside the outer shell 1 drives the transmission plate 81 to reciprocate. The power is transmitted to the grate 83 through the connecting plate 84 and the connecting shaft 85. The connecting shaft 85 slides along the outer shell 1, driving the grate 83 to push the waste slag to achieve step-like crushing. In the dust removal mechanism 3, the telescopic rod 34 drives the pushing block to slide along the supporting base plate 7, pushing the accumulated ash to the ash cleaning port 31 outside the outer shell 1. The ash cleaning port 31 opens and closes by sliding the sliding strip 33 within the limiting block 32. In the slag scraping mechanism 5, the motor 56 fixed in the support frame 51 drives the sprocket 52 to rotate. The chain 53 drives the baffle 55 to transport the waste slag through the connecting plate 54. The coordinated pushing, ash cleaning and transportation reduce slag jamming and material jamming, lower the slag discharge failure rate, and ensure the stable operation of the system.

[0040] The implementation principle of this application embodiment is as follows: After the biomass fuel is burned in the waste liquid furnace, the resulting waste residue and unburned solid waste fall to the feed port above the grate 83 inside the outer shell 1 at the bottom of the waste liquid furnace under the action of gravity. Then, the transmission plate 81 is driven by the oil cylinder 82 to reciprocate. At the same time, the transmission plate 81 is linked with the connecting shaft 85 through the connecting plate 84, so that the grate 83 slides along the inside of the outer shell 1, and pushes the waste residue on the grate 83 to move towards the slag discharge end. During the pushing process, the grate 83 with a stepped structure conveys the waste residue from top to bottom step by step, and uses the height difference to initially crush large pieces of waste residue, reducing the load on subsequent equipment.

[0041] Protective air is continuously supplied through the air inlets 4 on both sides inside the outer shell 1. When the air flows through the gaps between the grate 83 plates, it carries away the heat from the surface of the grate 83, providing cooling protection for the grate 83. Since the grate 83 is made of high-chromium cast iron, the convective cooling of the protective air can maintain its safe temperature range, preventing the grate 83 from deforming or breaking due to overheating, thereby ensuring the stable operation of the equipment. In addition, the protective air also provides oxygen to the unburned solid waste on the grate 83, promoting complete combustion and achieving a balance between incineration efficiency and environmental protection requirements, forming a safe buffer between ultra-high temperature and material limits.

[0042] The hydraulic cylinder 62 is activated, and its drive end pushes the transmission block 63 to perform a telescopic movement. The transmission block 63 drives the externally rotatably connected transmission plate 64 to move synchronously. Since the transmission plate 64 is externally slidably connected to the outside of the limiting frame 61, and the limiting frame 61 has arc-shaped limiting grooves 662 on both sides, the transmission plate 64 slides along the trajectory of the arc-shaped limiting grooves 662 during the movement. At the same time, the transmission plate 64 is fixedly connected to the cleaning plate 65 through the connecting post 661, so that the cleaning plate 65 moves with the movement of the transmission plate 64. The reciprocating motion of the cleaning plate 65 cleans the surface and gaps of the grate 83 to prevent ash accumulation. At the same time, fine ash falls through the gaps of the grate 83 to the bottom air chamber. The sliding block is pushed along the support base plate 7 by the telescopic rod 34, pushing the accumulated ash to the ash cleaning port 31. The ash cleaning port 31 opens and closes by sliding the sliding strip 33 within the limit block 32, and is discharged from the dust guide plate 2 for easy manual removal of accumulated ash during maintenance shutdowns, avoiding blockage of the air chamber and affecting the primary air distribution, while also preventing the ash from hardening and jamming the transmission components.

[0043] The waste slag pushed by the end of the grate 83 enters the slag scraping mechanism 5 by gravity free fall due to the height difference of the stepped structure. The slag scraping mechanism 5 drives the sprocket 52 to rotate through the motor 56, and drives the connecting plate 54 and the baffle 55 to move along the support frame 51 through the chain 53, so as to stably transport small pieces of ash slag to the collection device. Thanks to the previous crushing treatment, the mechanical impact on the scraper is reduced, which effectively reduces the failure rate of slag jamming and material jamming and extends the service life of the equipment.

[0044] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
