[0037] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0038] This utility model provides a slag bin discharge door, such as Figure 1 , Figure 2 , Figure 3 As shown, the slag bin 4 includes a support body 1, a water supply component 3, and a valve plate 2. The slag outlet at the bottom of the slag bin 4 is connected to the support body 1. The support body 1 has a sliding channel 11 inside. The valve plate 2 is slidably configured in the sliding channel 11, so that the slag outlet can switch between an open state and a closed state. When the slag outlet is in the open state, the slag and other waste in the slag bin 4 can be discharged through the slag outlet. When the slag outlet is in the closed state, the slag and other waste in the slag bin 4 cannot be discharged through the slag outlet.

[0039] like Figure 1 , Figure 2 As shown, a support wheel 12 is arranged on the support body 1. The support wheel 12 is located in the sliding channel 11. The bottom of both sides of the valve plate 2 is supported on the support wheel 12. The support wheel 12 is equipped with a bearing 121 so that the support wheel 12 rolls when the valve plate 2 slides. The bearing 121 is preferably a double face-to-face rolling bearing, such as a 71907AC / DF type double face-to-face rolling bearing. This utility model changes the movement of the valve plate 2 from sliding to rolling by arranging the bearing 121 on the support wheel 12, which reduces friction and avoids wear and jamming of the support wheel 12.

[0040] like Figure 1 , Figure 2 , Figure 3 As shown, to prevent slag accumulation between the support wheel 12 and the sliding channel 11, a water supply component 3 is arranged below the slag outlet. Specifically, the water supply component 3 is arranged on the support body 1 and extends into the sliding channel 11, and can rinse the support wheel 12 and part of the sliding channel 11. The water supply component 3 includes a water supply header 31 and a nozzle 32, with the nozzle 32 arranged at the end of the water supply header 31.

[0041] In practical applications, multiple nozzles 32 are used, and these nozzles 32 can be configured with different orientations to flush different support wheels 12 and different parts of the sliding channel 11. In one possible embodiment, two rows of four nozzles 32 are added below the slag outlet to flush the sliding channel 11 and support wheels 12 when necessary. The flushing valve is controlled by a solenoid valve, which is configured on the water supply header 31 and can be interlocked with the valve plate 2. For example, flushing can start automatically when the valve plate 2 is closed to one-third and stop automatically after a 30-second delay after it is fully closed. Flushing can also be performed manually. Figure 3 As shown.

[0042] The valve plate 2 in this utility model can be driven by an electric cylinder or a pneumatic cylinder, and the specific choice can be made flexibly according to the actual application scenario.

[0043] like Figure 2 As shown, the support wheel 12 is mounted on the support body 1 via the support shaft 122. The support shaft 122 passes through the side wall of the support body 1. The inner end of the support shaft 122 is mounted on the support wheel 12 via the bearing 121. A positioning seat 123 is mounted on the outside of the support body 1. The outer end of the support shaft 122 extends to the outside of the support body 1. The positioning seat 123 is fitted onto the outer end and fixed to the outside of the support body 1 with screws, so that the support shaft 122 can be stably mounted on the support body 1.

[0044] To prevent the support shaft 122 from rotating or moving axially, the positioning seat 123 is positioned on the outer end of the support shaft 122 by the positioning element 1221, such as... Figure 2 As shown, since the positioning seat 123 is fixed to the support body 1 by screws, the positioning member 1221 is arranged perpendicular to the support shaft 122. The surface of the support shaft 122 has a positioning hole, and the positioning member 1221 extends through the positioning seat 123 into the positioning hole along the radial direction of the support shaft 122.

[0045] like Figure 4 As shown, in order to enhance the connection strength between the support body 1 and the lower cone of the slag bin 4, a reinforcing ring 41 is provided between the lower cone of the slag bin 4 and the support body 1. The reinforcing ring 41 can be made of annular steel plate. The upper end of the annular steel plate is fixed on the lower cone of the slag bin 4, and the lower end of the annular steel plate is fixed on the support body 1. Preferably, the upper end and the lower end of the annular steel plate are welded to the lower cone of the slag bin 4 and the support body 1, respectively.

[0046] To improve the sealing effect between the slag outlet and valve plate 2, an inflatable sealing ring is installed between them. This inflatable sealing ring is an expandable seal, typically made of elastic materials such as rubber or silicone, and has an internal inflation chamber. When gas, such as compressed air, is injected into the chamber, the inflatable sealing ring expands and tightly adheres to the sealing surface, thus preventing leakage of gas, liquid, or solid particles and achieving a sealing effect. In this invention, the opening and closing action of valve plate 2 is interlocked with the inflation state of the inflatable sealing ring. When the inflatable sealing ring is inflated, valve plate 2 cannot open or close; it can only open or close after the inflatable sealing ring is deflated. The sealing ring cannot be inflated if valve plate 2 is not fully closed. This improves the sealing performance of valve plate 2 and extends the service life of the inflatable sealing ring.

[0047] This utility model also provides a slag bin, which is equipped with a slag bin discharge gate.

[0048] The working principle of this utility model is as follows:

[0049] When the valve plate 2, which is in the closed state, needs to be opened, the air-filled sealing ring is first controlled to release air. After the air is released, the cylinder is controlled to drive the valve plate 2 to move towards the outside of the support body 1 and gradually open it. After it is opened, when the slag and other waste in the slag bin 4 have been discharged or it needs to be closed, the cylinder is controlled to drive the valve plate 2 to move towards the inside of the support body 1 and gradually close it. When the valve plate 2 is closed to one-third, the nozzle 32 automatically starts flushing. After it is closed, the flushing automatically stops after a delay of 30 seconds. After the valve plate 2 is fully closed, air is injected into the air-filled sealing ring to achieve a seal between the slag outlet and the valve plate 2.
