[0032] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0033] like Figures 1 to 5As shown, the ash unloading mechanism disclosed in the first embodiment of the present application includes: an ash unloading assembly 10 and a collecting assembly 20. The ash unloading assembly 10 includes an ash unloading structure 11, a accommodating chamber structure 12 and a discharge structure 13. The ash unloading structure 11 includes a first hopper 111 and a first discharge door 112. The first hopper 111 is connected to the accommodating chamber structure 12 and is arranged in the accommodating chamber structure 12. The first discharge door 112 is rotatably connected to the accommodating chamber structure 12. The first discharge door 112 has a closed state close to the first hopper 111 and an open state away from the first hopper 111. The discharge structure 13 is movably connected to the accommodating chamber structure 12. There is a predetermined distance between the discharge structure 13 and the first discharge door 112. The collecting assembly 20 is communicated with the accommodating chamber structure 12.

[0034] Using the technical solution of Example 1, the dust removal assembly 10 is installed in the dust removal chamber of the glass kiln, and the accommodating chamber structure 12 is arranged corresponding to the opening of the dust removal chamber. When the dust removal chamber needs to be cleaned, the discharge structure 13 is closed, the first discharge door 112 is opened, and the dust in the dust removal chamber falls onto the discharge structure 13. During this process, the dust removal chamber is connected to the accommodating chamber structure 12. The volume of the accommodating chamber structure 12 is limited. Compared with the method of directly connecting the dust removal chamber to the outside world, the installation of the dust removal assembly 10 can reduce the reduction value of the internal pressure of the kiln, and the kiln pressure is stable. The technical solution of Example 1 effectively solves the problem of unstable kiln pressure during the cleaning process of the dust removal chamber of the glass kiln in the prior art.

[0035] like Figures 1 to 5 As shown, in the technical solution of Example 1, the first discharge door 112 includes a blocking portion 1121, a rotating portion 1122 and a first operating portion 1123. The blocking portion 1121, the rotating portion 1122 and the first operating portion 1123 are connected in sequence. The rotating portion 1122 is rotatably connected to the accommodating chamber structure 12. The blocking portion 1121 is located in the accommodating chamber structure 12 and is arranged corresponding to the first hopper 111. The first operating portion 1123 is arranged outside the accommodating chamber structure 12. The staff rotates the first operating portion 1123 to drive the rotating portion 1122 to rotate, and then drives the blocking portion 1121 to move closer to or away from the first hopper 111, thereby realizing the switching between the blocking state and the state to be blocked. The first operating portion 1123 is arranged outside the accommodating chamber structure 12 to facilitate the staff's operation. Controlling the rotation angle of the first discharge door 112 can control the kiln pressure fluctuation value to ensure process stability.

[0036] like Figure 1 、 Figure 2 and Figure 5As shown, in the technical solution of Example 1, the accommodating cavity structure 12 includes a first connecting section 121 and a second connecting section 122. The first connecting section 121 is connected to the second connecting section 122. The vertical projection area of ​​the second connecting section 122 is larger than the vertical projection area of ​​the first connecting section 121. The first hopper 111 is partially located in the first connecting section 121 and connected to the first connecting section 121. The rotating portion 1122 is passed through the second connecting section 122 and is rotatably connected to the second connecting section 122. The cross-sectional area of ​​the first hopper 111 continuously decreases in the direction from approaching to away from the first discharge door 112. When the first discharge door 112 is in the closed state, its vertical projection area is larger than the vertical projection area of ​​the end of the first hopper 111 near the first discharge door 112, to ensure that dust is not easily leaked when closed. The vertical projection of the rotating part 1122 is located outside the vertical projection of one end of the first hopper 111 close to the first discharge gate 112. On the one hand, it avoids interference between the rotating part 1122 and the first hopper 111, and on the other hand, it reduces dust falling onto the rotating part 1122 and hindering the rotation of the rotating part 1122.

[0037] like Figure 1 、 Figure 2 and Figure 5 As shown, in the technical solution of Example 1, the accommodating cavity structure 12 also includes a third connecting section 123, which is connected to the second connecting section 122. The third connecting section 123 is located at the end of the second connecting section 122 away from the first connecting section 121. The cross-sectional area of ​​the third connecting section 123 decreases as it approaches and moves away from the second connecting section 122. The third connecting section 123 is provided to reserve space for the rotation of the first discharge door 112 and to contain dust discharged from the kiln. The continuously decreasing cross-sectional area of ​​the third connecting section 123 facilitates the collection of dust at the bottom of the third connecting section 123. The vertical height of the third connecting section 123 is greater than the rotation radius of the blocking portion 1121, thereby reserving sufficient space for dust to fall.

[0038] like Figure 1 、 Figure 2 and Figure 5 As shown, in the technical solution of Example 1, the mass of the first operating portion 1123 is greater than the mass of the blocking portion 1121. Since the rotating portion 1122 is located between the first operating portion 1123 and the blocking portion 1121, the entire first discharge door 112 forms a lever structure. By properly arranging the masses of the first operating portion 1123 and the blocking portion 1121, it is possible to ensure that when the operator is not operating the first discharge door 112, the blocking portion 1121 is always in a closed state, which is more labor-saving.

[0039] like Figure 1 、 Figure 2 and Figure 5 As shown, in the technical solution of Example 1, the mass of the end of the first operating portion 1123 away from the rotating portion 1122 is greater than the mass of the end of the first operating portion 1123 closer to the rotating portion 1122. According to the principle of leverage, the product of the force and the force arm is equal to the product of the resistance and the resistance arm. Therefore, the greater mass of the end of the first operating portion 1123 closer to the rotating portion 1122 increases the product of the force and the force arm of the first operating portion 1123, thereby allowing more dust to accumulate above the blocking portion 1121.

[0040] like Figures 1 to 4 As shown, in the technical solution of Example 1, the end of the third connecting section 123 away from the second connecting section 122 has a groove, and the discharge structure 13 is movably disposed within the groove. The opening and closing of the discharge structure 13 is controlled by controlling the horizontal movement of the discharge structure 13, thereby discharging the material below the first discharge door 112. The groove limits the movement direction of the discharge structure 13, guiding its movement and preventing it from shifting.

[0041] like Figures 1 to 4 As shown, in the technical solution of Example 1, the width of the groove decreases as it approaches and moves away from the second connecting section 122. The discharge structure 13 includes a second discharge gate 131, which has the same shape as the groove. That is, the upper groove width is greater than the lower groove width. The groove acts as a limit for the second discharge gate 131, preventing the second discharge gate 131 from escaping from the groove under the action of gravity and causing it to fall off.

[0042] like Figures 1 to 4 As shown, in the technical solution of Example 1, the discharge structure 13 also includes a second operating portion 132, which is connected to the second discharge gate 131. The second operating portion 132 includes a connecting portion and a ring. The first end of the connecting portion is connected to the second discharge gate 131, and the second end of the connecting portion is connected to the ring. Workers can insert their hands or tools into the ring to operate the discharge structure 13. Compared to directly operating the second discharge gate 131, the provision of the ring converts friction into pulling or pushing force, making operation more convenient and less labor-intensive.

[0043] like Figures 1 to 3As shown, in the technical solution of Example 1, the collection assembly includes a connecting structure and a holding structure. The connecting structure is connected to the holding structure and is connected to the third connecting section 123. During use, the discharge structure 13 is first closed, and the first discharge door 112 is opened. Dust in the dust removal chamber falls onto the second discharge door 131. The amount of dust falling is controlled to ensure that the movement path of the first discharge door 112 is not blocked by dust when the first discharge door 112 is closed. After the first discharge door 112 is closed, the discharge structure 13 is opened, dust falls into the holding structure, and the discharge structure 13 is closed. When there is too much dust in the holding structure, a new collection assembly can be replaced.

[0044] The technical solution of Example 2 differs from that of Example 1 in that the dust removal mechanism of Example 2 further includes a vibration assembly, which is connected to the dust removal assembly 10. The vibration assembly includes a motor, an eccentric weight, and a housing. The eccentric weight is connected to the output shaft of the motor. The eccentric weight is disposed within the housing, which is connected to the outer wall of the accommodating cavity structure 12. When the motor is started, the eccentric weight rotates. The centrifugal force of the eccentric weight drives the housing and the accommodating cavity structure 12 to vibrate. Dust on the inner wall of the accommodating cavity structure 12 is shaken off, preventing dust from accumulating on the inner wall of the accommodating cavity structure 12.

[0045] The difference between the technical solution of Example 3 and the technical solution of Example 1 is that the dust unloading assembly 10 also includes a cleaning structure, the cleaning structure includes a driving part and a scraper, the cleaning structure is connected to the third connecting section 123, when the first discharge door 112 is fully opened, the guide rail of the driving part is parallel to the blocking part 1121, and the driving part drives the scraper to move on the surface of the blocking part 1121 to scrape off the dust on the surface of the blocking part 1121 to avoid dust accumulation.

[0046] According to another aspect of the present application, a glass kiln dust removal bin is provided. The glass kiln dust removal bin adopts the above-mentioned dust unloading mechanism. An ash discharge port is provided at the bottom of the glass kiln dust removal bin. The accommodating cavity structure 12 is connected to the bottom of the glass kiln dust removal bin. The first hopper 111 is provided corresponding to the ash discharge port. Dust accumulates at the ash discharge port. When a lot of dust accumulates, the first discharge door 112 is opened. At this time, the discharge structure 13 is in a closed state. The kiln is connected to the accommodating cavity structure 12, and the kiln pressure is relatively stable. After the dust in the dust removal bin is discharged, the first discharge door 112 is closed, the discharge structure 13 is opened, and the dust falls into the collection assembly. During the entire process, the kiln is only connected to the accommodating cavity structure 12. Compared with the cleaning method in which the kiln is connected to the outside world, the ash unloading mechanism of the present application can reduce the kiln pressure fluctuation value and ensure process stability.

[0047] From the above, it can be seen that the purpose of this utility model is to provide a new type of dust removal chamber ash unloading device (ash unloading mechanism) that is easy to operate, lightweight and labor-saving, and can be adjusted in size to avoid kiln pressure fluctuations. Due to the large suction force in the flue and the dust removal chamber, the external flip-up discharge port of the dust removal chamber is difficult to open and close due to the interaction of forces caused by the suction force of the induced draft fan. In order to reduce the difficulty in opening the ash unloading port during use, a heavy hammer type flap valve (first discharge door 112) is designed and manufactured. When the flap valve is opened, the volatiles automatically fall into the lower ash bucket; by replacing the ash bucket (collection component 20), the efficiency of the ash unloading operation can be improved and the kiln pressure stability can be improved. This application is divided into three parts, one is the flap regulating valve (first discharge door 112), the second is the middle pull-out gate (discharge structure 13), and the third is the ash bucket (collection component 20); the flap regulating valve is a flap (sealing part 1121) placed inside, the internal flap is connected to the external wrench (first operating part 1123), and the purpose of adjusting the internal flap valve is achieved by adjusting the external wrench; when the adjusting wrench is used, the flap amplitude of the internal flap valve can be adjusted, and the flap opening size can be adjusted by the wrench amplitude, so that Slowly adjust the ash unloading opening to reduce kiln pressure fluctuations when the ash unloading port is opened and closed, and reduce the impact of the ash unloading process on the kiln pressure; the pull-out gate is a connecting device located between the flap valve and the ash loading bucket. Place the ash loading bucket under the pull-out gate. When there is no gap between the ash loading bucket and the gate, pull out the gate at the pull-out gate, and the volatiles in the dust removal chamber will automatically fall into the ash loading bucket below; the ash loading bucket is placed under the gate and can store volatiles in the dust removal chamber after the gate is opened. When the volatiles are full, put the gate back and replace the ash loading bucket. The new ash unloading port is based on the traditional ash unloading port and adds a flap regulating valve (first discharge door 112), and a new pull-out valve (discharge structure 13) is added below. After the pull-out gate is opened, it will be directly connected to the ash unloading bucket below; the traditional ash unloading port is a flip-up opening. During the ash unloading operation, a cloth bag is used to wrap the bottom of the ash unloading port to allow volatiles to flow into the cloth bag. When the dust removal bag completely wraps the ash unloading port, it will be very difficult to open the traditional flip-up ash unloading port, and the moment of opening will cause the kiln pressure to instantly contact with the external pressure, causing the kiln pressure to rise instantly. The new ash unloading port is transformed into three parts after design and modification: the improvement made by the new ash unloading port (accommodating chamber structure 12) compared with the traditional ash unloading port is that the switch flap valve is placed inside the ash unloading port, and the control switch is placed outside the ash unloading port. This avoids the pain point of the traditional ash unloading port of putting the hand into the bag, and the switch outside the ash unloading port reduces the influence of the internal fan suction. The internal flap valve can be easily controlled from the outside and the opening and closing speed of the flap valve is controlled to cooperate with the lower pull-out gate plate to form a buffer room between the flap valve and the pull-out gate plate, thereby reducing the pressure difference between the inside and outside of the dust removal chamber, thereby achieving the purpose of controlling the kiln pressure, reducing the kiln pressure fluctuation, and maintaining the stability of the kiln process.Pull-out gate: The pull-out gate is located between the ash discharge port and the ash bin. It not only forms a buffer with the flap valve above, but also connects to the ash discharge bin below to prevent volatiles from falling when the flap valve is opened. Ash discharge bin: The ash discharge bin mouth fits in with the upper ash discharge port, allowing for a seamless connection between the ash discharge port and the ash discharge bin. When the pull-out gate is opened, volatiles automatically fall into the ash discharge bin due to the vibration of the dust removal chamber. Once the volatiles fill the ash discharge bin, the ash discharge bin is replaced, achieving automatic ash discharge from the dust removal chamber.
