[0022] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.
[0023] like Figure 1-3 As shown, the utility model proposes a zero-leakage double-layer ash hopper inspection door, comprising an ash hopper outer bin 1 and an ash hopper inner bin 5, wherein the ash hopper inner bin 5 is arranged in the inner cavity of the ash hopper outer bin 1;
[0024] The outer door mechanism comprises an outer door frame 21 arranged on the top of the ash hopper outer bin 1, an outer door 23 is arranged above the outer door frame 21, and an outer door seal 22 for sealing is arranged in the gap between the two;
[0025] The opening and closing mechanism includes an opening and closing frame 31 arranged on one side of the ash hopper outer bin 1, a driving device 32 is installed on the opening and closing frame 31, and a valve connecting rod 33 connected to the outer door 23 is installed at the output end of the driving device 32;
[0026] The inner door mechanism comprises an inner door frame 61 arranged on the top of the ash hopper inner bin 5, an inner door 63 is arranged on the inner door frame 61, an inner door seal 62 is clamped in the gap between the two, and an opening and closing mechanism is also arranged on one side of the inner door 63.
[0027] It should be noted that the ash hopper outer bin 1 and the ash hopper inner bin 5 are separated into two independent cavities by an outer door mechanism and an inner door mechanism; the ash hopper inner bin 5 and the inner door mechanism are combined into an inner sealed cavity, and the ash hopper outer bin 1 and the outer door mechanism are combined into an outer sealed cavity.
[0028] Among them, the outer door is a 730×680mm square door, and the inner door is a φ600mm round door.
[0029] In this embodiment, the ash hopper inspection door is a double-layer design, and the inner door mechanism directly contacts the inner cavity of the ash hopper. When leakage occurs at the connection, the ash hopper outer chamber 1 and the outer door mechanism installed outside can continue to act as a sealing structure, isolating the leaked exhaust gas and dust in the outer sealing cavity, thereby ensuring zero air leakage rate when the dust collector is in use.
[0030] It should be added that: the outer door seal 22 and the inner door seal 62 are both foamed silicone strip components. The foamed silicone strip is an extruded silicone type and mainly plays a sealing role. It fills the gaps in the door frame connected to the seal. The upper edges of the outer door frame 21 and the inner door frame 61 connected thereto are polished and rounded. The purpose of polishing and rounding is to increase the tightness of adhesion.
[0031] As a working example of the opening and closing mechanism: the valve connecting rod 33 includes an axial rod section connected to the output end of the driving device 32 and a door connecting section connected to the outer door 23. The driving device 32 drives the axial rod section at the output end to rotate on the opening and closing frame 31, thereby driving the outer door 23 connected to the door connecting section to rotate outward and open.
[0032] It can be understood that the opening and closing mechanism connected to the inner door 63 has the same structure as the opening and closing mechanism connected to the outer door 23, and the inner door 63 can be opened in the same manner.
[0033] In order to block and limit the outer door 23, a door blocking frame 41 is further provided on one side of the ash hopper outer bin 1, and a rotatable door blocking rod 42 is installed on the door blocking frame 41. The door blocking rod 42 is an "L-shaped" structure, and the bent end face is attached to the outer door 23, and external limiting is performed by the protruding door blocking rod 42.
