On the upper side of the sealing component, the furnace body is sleeved on the outer side of the sealing component and rotatably mounted on the upper side of the bracket. Multiple downward oblique teeth are installed on the lower part of the inner wall of the furnace body. The downward oblique teeth rotate synchronously with the furnace body. The multiple downward oblique teeth are arranged in a ring on the inner wall of the furnace body. The mounting component is installed on the upper part of the inner wall of the furnace body and is located above the sealing component. The adjusting rod is installed on the outer side of the furnace body and rotates synchronously with the furnace body. A positioning mechanism is sleeved on the outer side of the adjusting rod. The positioning mechanism is used to position the adjusting rod.

[0006] As a preferred embodiment of the ash discharge port sealing device for the buffer tank described in this utility model, in order to achieve rotational locking between the upper oblique tooth and the lower oblique tooth, the upper oblique tooth is provided with a downward slope, and the lower oblique tooth is provided with an upward slope, and the upper oblique tooth and the lower oblique tooth are adapted to each other.

[0007] As a preferred embodiment of the ash discharge port sealing device for buffer tanks described in this utility model, in order to enhance the sealing effect of the sealing ring between the sealing device and the ash discharge port, thereby enhancing the sealing effect of the sealing device, the sealing ring is annular in shape and is located in the area between the sealing component and the mounting component.

[0008] As a preferred embodiment of the ash discharge port sealing device for buffer tanks described in this utility model, the connecting member is narrow at the top and wide at the bottom in order to improve the installation effect of the mounting member on the sealing device.

[0009] The positioning mechanism includes a mounting plate, a moving rod, a return spring, and an abutment positioning plate. The mounting plate covers the outside of the adjusting rod. Two moving rods are inserted into the mounting plate. The moving rods can move vertically inside the mounting plate. The return spring is sleeved on the moving rod. The two ends of the return spring are respectively connected to the mounting plate and the moving rod. The abutment positioning plate is installed on the upper end of the moving rod and moves synchronously with the moving rod.

[0010] As a preferred embodiment of the ash discharge port sealing device for the buffer tank described in this utility model, in order to enhance the abutting and positioning effect of the abutting positioning plate, thereby ensuring the positioning effect of the positioning mechanism on the adjusting rod and reducing the probability of the adjusting rod deviating from its original position without cause, an anti-slip pad is provided on the upper side of the abutting positioning plate, and the anti-slip pad is an elastic anti-slip pad.

[0011] As a preferred embodiment of the ash discharge port sealing device for the buffer tank described in this utility model, in order to achieve the snap-fit ​​installation between the snap-fit ​​block and the mounting plate, thereby ensuring the installation effect of the positioning mechanism and facilitating the installation or disassembly of the positioning mechanism by the staff, the snap-fit ​​block is sleeved on the outer side of the adjusting rod, and the mounting plate is sleeved on the snap-fit ​​block and snap-fitted with the snap-fit ​​block.

[0013] The beneficial effects of the embodiments disclosed herein are as follows:

[0014] In this disclosure, compared with the existing technology of buffer tank ash discharge port sealing device, the structure is relatively simple and it is difficult to lock the sealing plug. This makes it easy for the sealing plug to be displaced by airflow during the use of the sealing device, which may affect the sealing effect of the sealing device on the ash discharge port. By cooperating the upper inclined teeth, furnace body, lower inclined teeth and adjusting rod, the rotation locking of the sealing plug is realized, which enhances the sealing effect of the sealing plug and sealing ring on the ash discharge port, reduces the probability of the sealing plug and sealing ring being displaced by airflow during the use of the sealing device, and ensures the sealing effect of the sealing device on the ash discharge port.

This ensures the rotational locking effect of the upper and lower inclined teeth, reduces the probability of the adjusting rod shifting due to external forces during the use of the sealing device, thus reducing the sealing effect of the sealing device and ensuring the sealing effect of the sealing device on the ash discharge port.

[0024] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0030] like Figures 1-5 As shown, this embodiment illustrates a buffer tank ash discharge port sealing device, including a bracket 1, a sealing element 2, an upper helical tooth 3, a sealing ring 4, a furnace body 5, a lower helical tooth 6, a mounting element 7, an adjusting element, and a positioning mechanism. Compared to existing buffer tank ash discharge port sealing devices, which have a relatively simple structure and are difficult to lock tightly, the sealing element is easily displaced by airflow during use, potentially affecting the sealing effect on the ash discharge port. In this embodiment, the upper helical tooth 3, the furnace body 5, the lower helical tooth 6, and the adjusting rod 8 work together to achieve proper sealing. The rotational locking of component 2 enhances the sealing effect of the sealing component 2 and sealing ring 4 on the ash discharge port, reduces the probability of displacement of the sealing component 2 and sealing ring 4 due to airflow during the use of the sealing device, and ensures the sealing effect of the sealing device on the ash discharge port. The positioning mechanism realizes the positioning of the adjusting rod 8, thereby realizing the positioning of the furnace body 5 and the lower helical tooth 6 after rotation, thus ensuring the rotational locking effect of the upper helical tooth 3 and the lower helical tooth 6, reducing the probability of displacement of the adjusting rod 8 due to external force during the use of the sealing device, thus ensuring the sealing effect of the sealing device on the ash discharge port.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, the sealing component 2 is installed on the upper side of the bracket 1. Multiple upward-sloping teeth 3 are installed on the outer side of the sealing component 2, arranged in a ring on the outer side. A sealing ring 4 is installed on the upper side of the sealing component 2, also in a ring shape. The sealing ring 4 is located in the area between the sealing component 2 and the mounting component 7. The ring-shaped sealing ring 4 can better adapt to the shape of the ash discharge port, thus providing a better seal for the ash discharge port and the sealing device. The furnace body 5 is fitted onto the outer side of the sealing component 2. Multiple downward-sloping teeth 6 are installed on the lower part of the inner wall of the furnace body 5, arranged in a ring on the inner wall. The mounting component 7 is installed on the upper part of the inner wall of the furnace body 5, above the sealing component 2. An adjusting rod 8 is installed on the outer side of the furnace body 5. Figure 4 As shown, the upper inclined tooth 3 has a downward slope, and the lower inclined tooth 6 has an upward slope. The upper inclined tooth 3 and the lower inclined tooth 6 are compatible. When the lower inclined tooth 6 rotates, the upper inclined tooth 3 can rotate and lock the sealing part 2, thereby enhancing the sealing effect of the sealing part 2. Through the cooperation of the upper inclined tooth 3, the furnace body 5, the lower inclined tooth 6 and the adjusting rod 8, the rotation and locking of the sealing part 2 can be achieved, reducing the probability of the sealing part 2 and the sealing ring 4 being displaced by the airflow during the use of the sealing device, and ensuring the sealing effect of the sealing device on the ash discharge port.

[0032] like Figure 1 As shown, a positioning mechanism is sleeved on the outer side of the adjusting rod 8, such as... Figure 4 As shown, the positioning mechanism includes a mounting plate 101, a moving rod 102, a return spring 103, and an abutment positioning plate 104. An anti-slip pad is provided on the upper side of the abutment positioning plate 104, which increases the friction between the abutment positioning plate 104 and the buffer tank, thereby enhancing the abutment positioning effect of the abutment positioning plate 104. A reinforcing seat is sleeved on the outer side of the moving rod 102, with its upper side connected to the lower side of the abutment positioning plate 104. The reinforcing seat is shaped like a hollow frustum, reinforcing the connection between the moving rod 102 and the abutment positioning plate 104, thus enhancing the abutment positioning effect of the moving rod 102. The positioning mechanism is securely installed between the positioning plates 104. A locking block 9 is sleeved on the outer side of the adjusting rod 8. The mounting plate 101 is sleeved on the locking block 9 and locked with the locking block 9. The positioning mechanism is set on the locking block 9 by locking, which allows the staff to quickly install or disassemble the positioning mechanism, improves the flexibility of the positioning mechanism, and facilitates the staff's application. The positioning mechanism can realize the positioning of the adjusting rod 8, ensuring the stability of the adjusting rod 8 after rotation, thereby ensuring the stability of the furnace body 5 and the lower helical tooth 6 after rotation, and ensuring the rotation locking effect of the upper helical tooth 3 and the lower helical tooth 6.

[0033] Working principle:

[0034] The worker attaches bracket 1 to the mounting column located below the ash discharge port of the buffer tank, hinged bracket 1 to the mounting column. After installation, the worker presses down the tail end of bracket 1, causing bracket 1 to abut the sealing structure against the ash discharge port. Then, the worker pulls the moving rod 102 downwards. During the movement of moving rod 102, the return spring 103 is stretched, and moving rod 102 drives the abutment positioning plate 104 downwards, canceling the positioning mechanism's positioning of adjusting rod 8. After cancellation, the worker rotates furnace body 5 via adjusting rod 8. The furnace body 5 drives multiple lower helical teeth 6 to rotate. During the rotation of the lower helical teeth 6, the upper helical teeth 3 push the sealing part 2 and the sealing ring 4 to move upward. The sealing part 2 and the sealing ring 4 seal the ash discharge port. During the rotation of the lower helical teeth 6, they cooperate with the upper helical teeth 3 to achieve rotational locking of the sealing part 2. After locking, the operator releases the moving rod 102. Under the action of the return spring 103, the moving rod 102 drives the abutting positioning plate 104 to abut against the buffer tank, thereby achieving the positioning of the adjusting rod 8 after rotation.
