[0022] The following description provides numerous specific details to offer a more thorough understanding of the technical solutions provided by this invention. However, it will be apparent to those skilled in the art that the technical solutions provided by this invention can be implemented without one or more of these details.
[0023] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

[0024] Exemplary embodiments according to the present invention will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of the invention is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art.
[0025] like Figure 1 As shown, in view of the above, a dry quenching coke dust-free ash unloading device is proposed according to the first aspect of the embodiments of this application, comprising: a mixing box 110; an ash hopper outlet pipe 120, one end of which is connected to the bottom of the ash hopper, and the other end is arranged inside the mixing box 110; a positive pressure diffuser 130, which is arranged inside the ash hopper outlet pipe 120 and covers the output end of the ash hopper outlet pipe 120; and a mixing element 140, which is arranged inside the mixing box 110; wherein, the ground of the mixing box 110 forms a slope, and the low-lying part of the slope is the output end of the mixing box 110.
[0026] The dry quenching dust-free ash unloading device provided in this application embodiment, during use, after the dump truck is parked, according to its load and preset discharge mass, first adds water to the mixing tank 110 to the set amount. Then, the ash in the ash silo is transported through the ash silo outlet pipe 120, and the positive pressure diffuser 130 at the output end of the ash silo outlet pipe 120 works simultaneously to evenly diffuse the ash into the water in the mixing tank 110. At the same time, the agitator 140 starts to stir the ash-water mixture; as the mixing process progresses, the rotation speed of the agitator 140 gradually decreases to adapt to the increased viscosity of the mixture. The slope of the mixing tank 110 ground guides the mixture to converge at the low-lying output end. After mixing is completed, the mixture is discharged from the output end to the dump truck, completing the ash unloading operation. This dry quenching dust-free ash discharge device achieves several advantages. First, it enables dust-free ash discharge. The positive pressure diffuser 130 at the output end of the ash hopper outlet pipe 120 directly diffuses the ash into the water, preventing the ash from contacting the air and generating dust, thus improving the operating environment and protecting personnel health. Second, it ensures uniform and efficient mixing. The positive pressure diffuser 130 and the agitator 140 work together to ensure thorough mixing of ash and water. The rotation speed of the agitator 140 can be adapted to changes in the viscosity of the mixture, ensuring mixing quality and preventing loose and broken discharge. Third, it ensures smooth discharge. The slope of the mixing tank 110 guides the mixture to converge at the output end, reducing residue in the tank, improving discharge efficiency, and making it compatible with ordinary dump trucks, thus reducing equipment procurement and maintenance costs.
[0027] Understandably, to ensure the dispersion effect, the positive pressure diffuser 130 is positioned below the water surface after water injection.
[0028] Understandably, in order to ensure the output effect of materials, the slope angle is a longitudinal slope of 1% to 5%.
[0029] In some examples, the agitator 140 can be a stirring paddle.
[0030] like Figure 1 As shown, in one feasible embodiment, the dry quenching coke dust-free ash unloading device further includes: a compressed air pipe 150, which is connected to the ash outlet pipe 120 of the ash hopper and is used to output compressed air to the ash outlet pipe 120 of the ash hopper; and an electric slide gate valve 160, which is connected to the ash outlet pipe 120 of the ash hopper and is used to control the opening and closing of the ash outlet pipe 120 of the ash hopper.
[0031] In this technical solution, when outputting ash, the electric slide gate valve 160 is opened, and the ash in the ash hopper enters the mixing tank 110 through the ash outlet pipe 120. Simultaneously, the compressed air pipe 150 outputs compressed air to the ash outlet pipe 120 to assist in the smooth transport of ash and prevent ash from accumulating and clogging the pipe. This setup achieves efficient ash transport and dust-free control. The compressed air output from the compressed air pipe 150 provides power for the ash transport within the ash outlet pipe 120, ensuring uniform and rapid ash flow and reducing the risk of blockage within the pipe. Simultaneously, it coordinates with the ash-water mixing within the mixing tank 110, preventing dust generation during the transport and mixing stages and improving the working environment. Furthermore, it enhances operational convenience and controllability. The electric slide gate valve 160 can precisely control the opening and closing of the ash outlet pipe 120. Combined with preset parameters from the controller, the ash feed rate can be flexibly adjusted to adapt to different discharge quality requirements, reducing manual intervention and improving the stability and efficiency of the ash unloading process. It also adapts to ordinary dump trucks, reducing equipment costs.
[0032] like Figure 1 As shown, in one feasible embodiment, the dry quenching dust-free ash unloading device further includes: a water inlet pipe 170, which is located on one side of the mixing tank 110, with its output end connected to the mixing tank 110. This configuration allows the water inlet pipe 170 to precisely supply water to the mixing tank 110. A fixed amount of water can be injected into the mixing tank 110 according to preset requirements, providing a basis for the mixing of ash and water. This allows the ash to quickly combine with water to form a semi-solid mixture, preventing ash dust from the source and ensuring a clean operating environment and the health of personnel. Simultaneously, a stable water supply ensures a precise ash-water mixing ratio. Combined with the mixing component 140 and the positive pressure diffuser 130, this allows for thorough mixing of ash and water, preventing the discharge from being too loose or too fragmented, improving the ash unloading quality. Furthermore, it is compatible with ordinary dump trucks, eliminating the need for expensive specialized equipment.
[0033] like Figure 1 As shown, in one feasible embodiment, the dry quenching coke dust-free ash unloading device further includes: a patrol platform 180, which is located above the mixing tank 110. The patrol platform 180 facilitates real-time monitoring by operators of the ash-water mixing and equipment operation status within the mixing tank 110, and provides safe operating space for subsequent maintenance of components such as the positive pressure diffuser 130 and the mixing paddle, improving the convenience and safety of device operation and maintenance. Furthermore, it serves as a closed top cover for the mixing tank 110, preventing dust from escaping from the top of the tank during mixing and ash unloading, thus enhancing the dust-free effect.
[0034] like Figure 1As shown, in one feasible embodiment, the dry quenching coke dust-free unloading device further includes a screw conveyor 190, with its input end located at the output end of the mixing tank 110. This configuration, where the input end of the screw conveyor 190 connects to the output end of the mixing tank 110, allows for precise reception of the well-mixed semi-solid ash material within the mixing tank 110, preventing dust generation during transfer and further enhancing the dust-free unloading effect. It can systematically transport the ash material to the dump truck, coordinating with the ash material convergence guided by the slope of the mixing tank 110, reducing ash residue within the tank and improving discharge efficiency. Simultaneously, the screw conveyor 190 provides stable and controllable transport, adapting to the discharge requirements of dump trucks with varying load capacities, eliminating the need for expensive dedicated conveying equipment, reducing equipment procurement and maintenance costs, and ensuring a continuous and smooth unloading process.
[0035] In one feasible implementation, the dry quenching coke dust-free unloading device further includes: a flow guide, which is arc-shaped, with one end hinged to the mixing tank 110 and the other end facing the screw conveyor 190. The arc-shaped flow guide, with one end hinged to the mixing tank 110 and the other end facing the screw conveyor 190, can precisely guide the mixed semi-solid ash material in the mixing tank 110 to converge at the input end of the screw conveyor 190, preventing ash material residue in the corners of the tank and improving ash material utilization and discharge efficiency. Its arc-shaped structure reduces ash material flow resistance, prevents ash material accumulation and blockage, and ensures smooth material conveying. Simultaneously, the hinged design allows for adjustment of the flow guide angle according to the ash material viscosity and conveying requirements, adapting to different working conditions, and guiding the ash material through a closed transfer process, preventing ash material exposure and dust generation, further enhancing the dust-free unloading effect and reducing manual cleaning costs.
[0036] like Figure 1 As shown, in one feasible embodiment, the dry quenching dust-free ash discharge device further includes: a frame 210 and a weighing sensor 200. A mixing tank 110 is mounted on the frame 210, and the weighing sensor 200 is located between the frame 210 and the mixing tank 110. This configuration provides stable support for the mixing tank 110, ensuring structural stability of the mixing tank 110 and its internal components (such as the mixing paddle and positive pressure diffuser 130) during mixing and discharge, preventing equipment shaking from affecting the uniformity of ash-water mixing or causing ash leakage. The weighing sensor 200, located between the frame 210 and the mixing tank 110, can accurately monitor the total weight of the ash-water mixture in the mixing tank 110 in real time. Combined with preset dump truck load parameters, it can automatically control the amount of water and ash added, ensuring accurate and controllable discharge quality, reducing human intervention errors, and providing data support for adjusting the ash-water ratio. This ensures that the mixed ash is semi-solid, further consolidating the dust-free ash discharge effect and improving the automation and reliability of the device.
[0037] In one feasible embodiment, the dry quenching dust-free ash discharge device further includes: a pretreatment component, which is disposed on the ash discharge pipe 120 of the ash hopper. The pretreatment component includes: a housing and a dispersing component, the housing being connected to the ash discharge pipe 120 of the ash hopper, and the dispersing component being rotatably connected to the housing.
[0038] In this technical solution, the dry quenching dust-free ash discharge device also includes a pretreatment component. During operation, the ash in the ash hopper first enters the housing of the pretreatment component on the ash discharge pipe 120. At this time, the rotatable dispersing component inside the housing is activated to break and disperse any clumps that may exist in the ash. The uniformly treated ash is then conveyed through the ash discharge pipe 120. Simultaneously, compressed air pipe 150 provides ventilation to assist ash conveying, and electric slide valve 160 controls the ash feed rate. Finally, the ash enters the mixing tank 110 to mix with water, and is then discharged via screw conveyor 190. This setup of the pretreatment component, through the dispersing component inside the housing, can break up ash clumps and uniformly disperse the ash, preventing clumps from clogging the ash discharge pipe 120, ensuring smooth ash conveying, and reducing equipment failures. Furthermore, after the dispersed ash enters the mixing tank 110, it can mix with water more quickly and thoroughly, shortening the mixing time, improving mixing efficiency and uniformity, and avoiding uneven mixing and loose discharge due to ash clumps. This further consolidates the dust-free ash discharge effect and reduces operation and maintenance costs.
[0039] In one feasible implementation, the dry quenching dust-free ash discharge device further includes a Venturi nozzle, which is positioned at the output end of the ash discharge pipe 120 of the ash hopper. This configuration, with the Venturi nozzle at the output end of the ash discharge pipe 120, utilizes the Venturi effect to create a stable negative pressure and airflow field. On one hand, it efficiently adsorbs and guides ash within the ash discharge pipe 120, preventing ash deposition and blockage at the pipe end, ensuring continuous and uniform ash delivery to the mixing tank 110. On the other hand, it precisely disperses ash into the water within the mixing tank 110, reducing the contact time between ash and air, thus lowering the probability of dust generation at the source. Simultaneously, its airflow assistance also aids in subsequent ash-water mixing, improving mixing efficiency and further solidifying the dust-free ash discharge effect of the device, adapting to the overall process requirements for efficient ash conveying and dust control.
[0040] like Figure 2 As shown, according to a second aspect of the embodiments of this application, a dry quenching dust-free ash removal method is proposed, applied to any of the above-described dry quenching dust-free ash removal devices. The dry quenching dust-free ash removal method includes: Step 201: Add water to the mixing tank; Step 202: Open the ash outlet pipe of the ash hopper. The ash outlet pipe of the ash hopper outputs ash, and the positive pressure diffuser ensures the water-ash mixing efficiency. Step 203: Turn on the agitator to mix the water and ash to form a mixture.
[0041] The dry quenching dust-free ash removal method provided in this application embodiment, because it is applied to the dry quenching dust-free ash removal device of any of the above technical solutions, therefore the dry quenching dust-free ash removal method has all the beneficial effects of the dry quenching dust-free ash removal device of the above technical solutions.
[0042] The dry quenching dust-free ash unloading method provided in this application embodiment, after the dump truck is parked, according to its load and preset discharge mass, the dry quenching dust-free ash unloading device first adds water to the mixing tank 110 to the set amount. Then, the ash in the ash hopper is transported through the ash hopper outlet pipe 120, and the positive pressure diffuser 130 at the output end of the ash hopper outlet pipe 120 works simultaneously to evenly diffuse the ash into the water in the mixing tank 110. At the same time, the agitator 140 starts to stir the ash-water mixture; as the mixing process progresses, the rotation speed of the agitator 140 gradually decreases to adapt to the increased viscosity of the mixture. The slope of the mixing tank 110 ground guides the mixture to converge at the low-lying output end. After mixing is completed, the mixture is discharged from the output end to the dump truck, completing the ash unloading operation. This dry quenching dust-free ash discharge device achieves several advantages. First, it enables dust-free ash discharge. The positive pressure diffuser 130 at the output end of the ash hopper outlet pipe 120 directly diffuses the ash into the water, preventing the ash from contacting the air and generating dust, thus improving the operating environment and protecting personnel health. Second, it ensures uniform and efficient mixing. The positive pressure diffuser 130 and the agitator 140 work together to ensure thorough mixing of ash and water. The rotation speed of the agitator 140 can be adapted to changes in the viscosity of the mixture, ensuring mixing quality and preventing loose and broken discharge. Third, it ensures smooth discharge. The slope of the mixing tank 110 guides the mixture to converge at the output end, reducing residue in the tank, improving discharge efficiency, and making it compatible with ordinary dump trucks, thus reducing equipment procurement and maintenance costs.
[0043] In one feasible implementation, the dry quenching coke dust-free unloading method further includes using a screw conveyor 190 to output the mixed material. This configuration allows the screw conveyor 190 to output the mixed material, orderly conveying the semi-solid agglomerated material prepared in the mixing tank 110 to the dump truck, preventing spillage or exposure of the mixed material during transfer and thus maintaining the dust-free effect. The conveying process is stable and controllable. Combined with the longitudinal slope of the mixing tank 110's bottom plate, it reduces material residue, improves unloading efficiency, is compatible with ordinary dump trucks, eliminates the need for expensive specialized equipment, and reduces equipment procurement and maintenance costs.
[0044] In some examples, the step of activating the agitator 140 to mix water and ash to form a mixture may include: agitating at a first speed in the initial stage of mixing, and a second speed (lower than the first speed) in the later stage of mixing. The agitator 140 agitates at the first speed in the initial stage of mixing, rapidly agitating the water. Combined with the positive pressure diffuser 130, this quickly disperses and integrates the ash that has just entered the mixing tank 110 into the water, shortening the initial mixing time and improving overall mixing efficiency. The lower second speed in the later stage of mixing accommodates the gradually increasing viscosity of the ash-water mixture, preventing high-speed agitation from causing splashing and dust generation, while also preventing damage to the equipment due to excessive resistance. This variable-speed agitation method ensures uniform mixing of the ash and water, preventing loose or broken output, further consolidating the dust-free effect, and improving the stability and safety of the device operation.
[0045] In some examples, the dry quenching dust-free ash discharge device may also include a controller that executes the aforementioned dry quenching dust-free ash discharge method. The controller can be a PLC controller, and the discharge quality can be set on the controller according to the load of the dump truck. The device automatically realizes the entire process of adding water, adding ash, and stirring. The PLC control system will automatically run until the program is completed, issuing a completion prompt sound, or issuing an alarm sound if a component malfunctions.
