Description

Technical Field

[0001] The utility model relates to the technical field of boilers, in particular to a device for centrally discharging boiler waste residue. Background Art

[0002] A boiler is a common device in industrial production. It burns fuels such as coal. When coal burns, the released heat energy is transferred to the water in the boiler, raising the water temperature and converting it into steam or hot water, thereby generating energy for the technological process or building. During the process of burning fuel, waste residue will be produced, which usually includes ash, particulate matter in flue gas, etc. In a coal-fired boiler, the ash produced by burning coal will be collected and treated to reduce the impact on the environment.

[0003] In the use of small boilers, waste residue is usually manually removed from the boiler by an operator using tools to ensure combustion efficiency and safe operation. Due to the relatively narrow space and limitations of operating conditions, manual cleaning of waste residue cannot completely remove all the waste residue in the boiler, especially in some corner positions. The boiler heating surface is the part inside the boiler that bears high temperature and high pressure, and special attention needs to be paid to its protection to ensure the safe operation of the boiler and extend its service life.

[0028] Embodiment 1

[0029] Referring to Figures 1 to 4 , this is the first embodiment of the present utility model. This embodiment provides a device for centrally discharging boiler waste residues, which can reduce the need for manual cleaning and improve the cleaning efficiency. It includes an installation unit 100, which includes a boiler seat 101, a base 102 provided on the boiler seat 101, and a lower grate 103 provided on the boiler seat 101;

[0030] A rotating unit 200, which includes a pressing component 201 provided outside the base 102, an extrusion component 202 provided on the pressing component 201, a reset component 203 provided inside the base 102, and a transmission component 204 provided on the base 102. The waste residues enter the boiler seat 101 through the lower grate 103 and precipitate on the upper surface of the base 102.

[0031] Specifically, a groove 201a is opened at a position near the outside of the upper surface of the base 102. Sector-shaped grooves 201c are opened on the inner walls on both sides of the groove 201a. A pedal 201b is rotatably connected to the two sides of the sector-shaped grooves 201c through a rotating shaft. The pedal 201b is rotatably connected to the groove 201a in a clockwise direction with the rotating shaft as the center. The existence of the sector-shaped groove 201c can limit the rotation range of the pedal 201b, thereby ensuring that it only rotates within a specific angle range. A displacement groove 202b is opened on the inner wall of the groove 201a. A trapezoidal plate 202c is arranged in the displacement groove 202b. One side of the trapezoidal plate 202c is in an inclined shape. An extrusion block 202a is arranged near the other side at the lower end of the two pedals 201b. The extrusion block 202a is triangular, and its lower end is in an inclined shape and is matched with the inclined surface of the trapezoidal plate 202c. The operator steps on the pedal 201b with the sole of the foot, and the pedal 201b can apply a squeezing force in the other direction to the trapezoidal plate 202c through the extrusion block 202a, so that the trapezoidal plate 202c slides in the other direction.

[0032] Further, a fixing seat 203a is installed at the bottom of the base 102. The fixing seat 203a is horizontally connected and flush with the bottom of the base 102, which can improve the stability of the base 102. A telescopic groove 203b is provided near the other end of the fixing seat 203a. A return spring 203c is arranged inside the telescopic groove 203b. A connecting rod 203d is arranged on the return spring 203c. The other end of the connecting rod 203d is elastically connected in the telescopic groove 203b through the return spring 203c. The connecting rod 203d is connected to the trapezoidal plate 202c near one end of its outer side. This enables the trapezoidal plate 202c to drive the connecting rod 203d to move synchronously. A rack 204a is arranged near the central position of the outer part of the connecting rod 203d. A rotating rod 204b is rotatably connected to the central position of the base 102. A gear 204c is arranged at the bottom of the rotating rod 204b inside the fixing seat 203a. The gear 204c is rotatably connected in the fixing seat 203a, and the rack 204a is meshed with the gear 204c. This enables the connecting rod 203d to move, and the gear 204c can be rotated clockwise through the rack 204a;

[0033] Wherein, the pushing plate 301a is fixedly connected to the rotating rod 204b, and is arranged above the base 102 and driven by the rotating rod 204b on the inner wall of the boiler base 101. The outermost side of the pushing plate 301a is attached to the inner wall of the boiler base 101, and its bottom is attached to the upper surface of the base 102. Driven by the rotating rod 204b, the pushing plate 301a moves along the inner wall of the boiler base 101. At the same time, the attachment of the bottom to the upper surface of the base 102 ensures the stability and smooth movement of the pushing plate 301a, so as to collect and process the waste residue on the inner wall of the boiler base 101.

[0034] During use, the staff steps on the pedal 201b with the sole of the foot. The pedal 201b squeezes the trapezoidal plate 202c through the extrusion block 202a. The trapezoidal plate 202c drives the connecting rod 203d to move to the other side. The other end of the connecting rod 203d exerts a pressure to the other side on the return spring 203c, causing the return spring 203c to contract to the other side. At the same time, the rack 204a drives the gear 204c to rotate meshingly under the drive of the connecting rod 203d, thereby driving the rotating rod 204b to rotate clockwise. The pushing plate 301a will push the waste residue in the boiler base 101 clockwise to the slag discharge port 302a for centralized collection. When the staff no longer steps on the pedal 201b, the extrusion block 202a will no longer continue to exert an extrusion force on the trapezoidal plate 202c. Thus, the connecting rod 203d will exert a pressure on the return spring 203c. This enables the return spring 203c to push the connecting rod 203d to move in one direction under the action of the stretching elastic force, and exert an extrusion force on the extrusion block 202a through the trapezoidal plate 202c to drive the pedal 201b to reset. The pedal 201b can repeat the above operations to improve the cleaning efficiency.

[0035] Example 2

[0036] Reference Figures 4 to 7 , which is the second embodiment of the utility model. Different from the previous embodiment, this embodiment provides a slag discharge unit 300 of a centralized discharge device for boiler waste slag, which solves the problem of how to better collect the waste slag in a centralized manner, and includes a slag discharge unit 300, including a pushing component 301 arranged in the boiler seat 101, a slag discharge component 302 arranged in the boiler seat 101, and a guide component 303 arranged in the boiler seat 101.

[0037] Furthermore, a plurality of elliptical grooves 301b are provided on the push plate 301a. When the boiler seat 101 is not cleaned for a long time, too much waste residue will accumulate. If it is cleaned at one time, the load on the gear 204c will be too large. If it is cleaned with brute force, the device may be damaged. When the height of the waste residue accumulation exceeds the elliptical groove 301b, as the push plate 301a rotates, the waste residue will flow from the right side of the push plate 301a through the elliptical groove 301b to the left side of the push plate 301a to achieve the second cleaning. In conjunction with Example 1, the push plate 301a will rotate counterclockwise, and an inclined panel 301c is provided on the left side of the push plate 301a. One side of the inclined panel 301c is in the shape of an inclined surface, which makes the push plate 301a rotate counterclockwise, and the waste residue on the left side of the push plate 301a will flow along the inclined panel 301c from the left side of the push plate 301a to the right side of the push plate 301a to wait for the second cleaning.

[0038] Furthermore, a slag discharge port 302a is provided on the outer side of the boiler seat 101, and a sliding door 302b is rotatably connected to one side of the inner wall of the slag discharge hole through a rotating shaft, and a guide plate 302d is fixedly connected to one side of the sliding door 302b. The guide plate 302d is arc-shaped, which plays a guiding role and can guide the waste slag out of the slag discharge port 302a. When the sliding door 302b and the boiler seat 101 are closed, the waste slag in the boiler seat 101 can be prevented from leaking out and damaging the working environment. At this time, the guide plate 302d and the inner wall of the boiler seat 101 overlap each other, and a receiving cover 302c is provided on the inner wall of the boiler seat 101 on the outer side of the guide plate 302d. The receiving groove is semicircular, and the guide plate 302d is rotatably connected to the receiving cover 302c with the rotating shaft as the center of the circle, and the outer wall of the receiving cover 302c can block the waste slag.

[0039] During use, first open the sliding door 302b and rotate it 90 degrees clockwise until it cannot rotate anymore. At this time, according to Embodiment 1, under the push of the push plate 301a, the waste residue will push the push plate 301a to be collected clockwise and pushed to the slag discharge port 302a. The waste residue will be blocked by the diversion plate 302d and will flow out of the slag discharge port 302a along the arc surface of the diversion plate 302d, completing the cleaning of the waste residue on the boiler seat 101.

[0040] Specifically, an activity groove 303a is opened inside the base 102 directly below the sliding door 302b. The connecting plate 303c is elastically connected to the activity groove 303a through a limiting spring 303b. And a first limiting plate 303d is arranged near one side of the upper part of the connecting plate 303c, and a second limiting plate 303e is arranged near the other side of the upper part of the connecting plate 303c. The first limiting plate 303d and the second limiting plate 303e penetrate through the upper surface of the base 102 and cooperate with the sliding door 302b.

[0041] During use, when the sliding door 302b and the boiler seat 101 are closed, the second limiting plate 303e is in contact with the sliding door 302b to limit the sliding door 302b so that it cannot rotate clockwise, which realizes the effect of blocking the slag discharge port 302a. When it is necessary to open the slag discharge port 302a, the first limiting plate 303d can be pressed first, applying a downward pressure to the limiting spring 303b through the connecting plate 303c, causing it to deform and store elastic potential energy. As the connecting plate 303c moves downward, it will drive the second limiting plate 303e to move downward. When the upper parts of the first limiting plate 303d and the second limiting plate 303e are on the same horizontal plane as the upper part of the base 102, at this time, the sliding door 302b can be opened without the second limiting plate 303e. After opening, the first limiting plate 303d can be released, and through the stretching elastic force of the limiting spring 303b, the connecting plate 303c is pushed to drive the first limiting plate 303d and the second limiting plate 303e to reset. During the slag discharge process, it is necessary to rotate the sliding door 302b 90 degrees clockwise. At this time, the second limiting plate 303e needs to be pressed to drive the first limiting plate 303d to move downward. At this time, the sliding door 302b can be rotated until it can no longer rotate clockwise, and then the second limiting plate 303e can be released. At this time, the first limiting plate 303d resets and will limit the sliding door 302b. Cooperating with Embodiment 1 and Embodiment 2, the waste residue can be diverted out to complete the cleaning of the waste residue on the boiler seat 101.

[0042] Embodiment 3

[0043] This is the third embodiment of the present utility model. Different from the previous embodiment, this embodiment provides a boiler heating surface protection device and a numerical simulation unit, including a diagnostic analysis component. The diagnostic analysis component includes a simulation model, a boiler damage mathematical model, a dynamic expert knowledge base, mined data information, and fault lead diagnosis and early warning.

[0044] Further, this process first uses a numerical simulation tool to simulate the boiler combustion process to obtain data such as temperature and flue gas velocity; then, based on the simulation data, real-time measurement data, and fault experience, a mathematical model and an expert knowledge base are established; next, a data mining and intelligent neural network algorithm are used to create an intelligent lead diagnosis model; finally, through digital twin technology, the boiler structure, operating parameters, and safety status are displayed in real time and early warnings are given. At the same time, correlation adjustment analysis and operation optimization control are performed on the damage condition of the heating surface to achieve closed-loop management, thereby preventing boiler failures and optimizing its operating status.

[0045] Importantly, it should be noted that the construction and arrangement of the present application shown in multiple different exemplary embodiments are merely illustrative.
