[0019] Specifically, please refer to Figures 1 to 3 , Figure 1 This is an overall front view of the dust accumulation and dust removal device applied to the straight air duct provided in the embodiment of the present application. Figure 2 for Figure 1 A magnified view at point A. Figure 3A schematic diagram of a partial cross-sectional structure at a buffer unloading bin provided for an embodiment of the present application. The dust accumulation and unloading device 100 applied to a straight air duct includes a straight air duct body 110, and the straight air duct body 110 is a prior art. The bottom of the straight air duct body 110 is connected to an ash collecting bin 120, and the ash collecting bin 120 is set at a suitable position selected on the straight air duct body 110. The ash collecting bin 120 is located at the lowest end of the straight air duct body 110, and is used to continuously collect dust in the straight air duct body 110. As the working time extends, the dust in the ash collecting bin 120 will continue to accumulate. The bottom of the ash collecting bin 120 is connected to a buffer unloading bin 130, and the buffer unloading bin 130 is used for unloading ash. At the same time, the setting of the buffer unloading bin 130 enables the present application to maintain the normal operation of the air duct during the unloading process. Specifically, the bottom of the buffer ash unloading bin 130 is connected to a pneumatic conveying pipe 140, and the pneumatic conveying pipe 140 can be connected to a negative pressure device to form a negative pressure, thereby taking away the dust discharged from the buffer ash unloading bin 130. It should be noted that the above-mentioned negative pressure device can also be a negative pressure pump at the air outlet end of the air duct system in the prior art. The ash collecting bin 120 and the buffer ash unloading bin 130 are connected through a first reducer 150, and a first sealing valve 151 is provided on the first reducer 150. The first sealing valve 151 is used to control the opening and closing of the first reducer 150, thereby controlling the connection or blocking between the ash collecting bin 120 and the buffer ash unloading bin 130. The buffer ash unloading bin 130 is connected to the pneumatic conveying pipe 140 through a second reducer 160. A second sealing valve 161 is provided on the second reducer 160. The second sealing valve 161 is used to control the opening and closing of the second reducer 160, and further control the opening and closing between the buffer ash unloading bin 130 and the pneumatic conveying pipe 140. A plurality of filter cartridge assemblies 131 are provided on the top of the buffer ash unloading bin 130. The plurality of filter cartridge assemblies 131 are all connected to the buffer ash unloading bin 130. The filter cartridge assemblies 131 are used to balance the air pressure in the buffer ash unloading bin 130 when the pneumatic conveying pipe 140 is opened. A vibration assembly 170 for vibrating the buffer ash unloading bin 130 is provided around the outer periphery of the buffer ash unloading bin 130, which is located in the middle of the buffer ash unloading bin 130. The vibration assembly 170 is used to vibrate the buffer ash unloading bin 130 when the pneumatic conveying pipe 140 is opened, so as to facilitate the dust attached to the inner wall of the buffer ash unloading bin 130 to fall off.

[0020] In the embodiment of the present application, the specific working process is that after the straight air duct has been working for a period of time, a certain amount of dust will be stored in the ash collecting bin 120, and at this time, the second sealing valve 161 is closed and the first sealing valve 151 is opened, and the dust accumulated in the ash collecting bin 120 will fall into the ash unloading bin. After a period of time, the first sealing valve 151 is closed and the second sealing valve 161 and the pneumatic conveying pipe 140 are opened. After the airflow enters the buffer ash unloading bin 130 from the filter cartridge assembly 131, the dust in the buffer ash unloading bin 130 is entrained and enters the pneumatic conveying pipe 140 together, thereby completing the ash discharge. During the ash discharge process, the vibration assembly 170 can be opened to facilitate the dust attached to the inner wall of the buffer ash unloading bin 130 to enter the pneumatic conveying pipe 140 together.

[0021] As can be seen from the above, in the embodiment of the present application, by setting the ash collecting bin 120, the dust in the straight air duct body 110 can be accumulated inside the ash collecting bin 120, and the buffer ash unloading bin 130, the first reducer 150, the second reducer 160, the first sealing valve 151 and the second sealing valve 161 are set, so that the first sealing valve 151 can control the connection or blocking between the ash collecting bin 120 and the buffer ash unloading bin 130, and the second sealing valve 161 can control the connection and disconnection between the buffer ash unloading bin 130 and the pneumatic conveying pipe 140. In this way, the transfer of dust from the ash collecting bin 120 to the buffer ash unloading bin 130 can be completed. At the same time, when the pneumatic conveying pipe 140 transfers the dust in the buffer ash unloading bin 130, the first sealing valve 151 can close the first reducer 150, so as not to affect the normal operation of the straight air duct body 110. In the embodiment of the present application, the vibration component 170 is also set to effectively avoid the problem that the ash collected on the inner wall of the buffer ash unloading bin 130 cannot be completely cleaned.

[0022] In some embodiments, the filter cartridge assembly 131 includes a cylinder body 131a connected to the buffer ash unloading bin 130, the top of the cylinder body 131a extends to the top of the buffer ash unloading bin 130 and is covered with a top cover 131b, the top of the top cover 131b is evenly provided with filter holes, and a dust bag 131c is provided inside the cylinder body 131a. In the embodiment of the present application, through the above arrangement, when the dust bag 131c needs to be replaced, it is only necessary to open the top cover 131b, remove the dust bag 131c, replace the new dust bag 131c, and then install the top cover 131b again, so that the replacement of the dust bag 131c is more convenient.

[0023] In some embodiments, at least one air intake valve 132 is provided on the top of the cylinder body 131a. In the embodiment of the present application, in order to avoid the problem that the filter cartridge assembly 131 collects dust, resulting in a decrease in air intake efficiency and thus affecting the ash delivery of the pneumatic conveying pipe 140, through the above arrangement, when the filter cartridge assembly 131 collects dust, the air intake valve 132 can be opened to intake air, so as to balance the stability of the air pressure in the buffer discharge table during the ash delivery process of the pneumatic conveying pipe 140.

[0024] In some embodiments, the buffer ash unloading bin 130 and the first reducer 150, as well as the buffer ash unloading bin 130 and the second reducer 160 are connected by flanges. In the embodiment of the present application, through the above arrangement, the buffer unloading bin can be easily disassembled and cleaned, and the first sealing valve 151 and the second sealing valve 161 can be closed during the disassembly of the buffer unloading bin, which will not affect the overall operation of the system.

[0025] In some embodiments, the vibration assembly 170 is fixed to the buffer ash unloading bin 130 through a fixing member 180. The vibration assembly 170 includes a support ring 171, which is sleeved on the outer periphery of the buffer ash unloading bin 130. A plurality of vibration motors 172 are evenly arranged on one side of the support ring 171 close to the buffer ash unloading bin 130, and the vibration end of the vibration motor 172 abuts against the outer wall of the buffer ash unloading bin 130. In the embodiment of the present application, the vibration motor 172 arranged on the support ring 171 during operation realizes the vibration of the buffer unloading bin by vibrating the outer wall of the buffer unloading bin, thereby quickly shaking off the dust on the inner wall of the buffer unloading bin.

[0026] In some embodiments, the fixing member 180 includes a plurality of C-shaped bent plates 181, the bent plates 181 include a first connecting plate 181a, the two ends of the first connecting plate 181a are respectively connected to the second connecting plates 181b at an angle, the supporting ring 171 is clamped between the first connecting plate 181a and the second connecting plate 181b, and the other ends of the two second connecting plates 181b are screwed to the outer wall of the buffer ash unloading bin 130. A specific setting method of the fixing member 180 is shown in the embodiment of the present application, and the above method can stably fix the vibration assembly 170, and the disassembly process is simple and easy.
