[0023] To further understand the content of this utility model, a detailed description of the utility model is provided in conjunction with the accompanying drawings.
[0024] Example
[0025] The suction and discharge tank air chamber device of this embodiment, such as Figure 1 , 2 As shown in Figure 3, the tank includes a tank body 10 and an air chamber 12 in the lower part of the tank body 10. The air chamber 12 is assembled from a side support plate 4 connected to the symmetrical side walls of the tank body 10, a perforated plate 2 connected to the lower end of the side support plate 4, and an air chamber side cover panel 9 laid on and connected to the top surface of the side support plate 4 and the middle partition plate 3. All connecting surfaces are welded together, and the air chamber 12 is separated by the middle partition plate 3. The perforated plate 2 and the side support plate 4 are perforated with through holes. There are multiple side support plates 4, which are made of 5mm thick steel plates and are welded to both sides of the bottom of the tank body 10 to increase the support strength. The middle partition plate 3 has no through holes and is also made of 5mm thick steel plates. It is welded to both sides of the bottom of the tank body 10, separating the air chamber 12 while also providing support. Together with the side support plates 4, it increases the support strength and prevents the plates from deforming. Each separated air chamber 12 is connected to an external air inlet pipe to purge each air chamber 12. The fluidized bed 8 is covered on top of the perforated plate 2 and installed around it with pressure strips and screws.
[0026] The original tank gas chamber side panel 9 was composed of 18 3mm thick steel plates, which were difficult to weld and prone to leakage due to welding problems. In this embodiment, it is changed to 4 plates with the same total area as the original 18 plates, and welded with 5mm thick steel plates, which greatly reduces the number of steel plate welding seams and eliminates leakage caused by welding problems.
[0027] The air chambers 12 are two symmetrical chambers located in the lower part of the tank body 10, namely the front air chamber 1 and the rear air chamber 11. Both the front and rear of the tank body 10 can be fully purged by gas. The bottom area of the tank body 10 was originally a single design with the air inlet at the rear of the tank body 10. Due to uneven air intake, ash discharge blockage occurred at the front of the tank body 10. Now, it is installed in two sections, front and rear, as the front and rear air chambers 12. During the ash discharge process, air is injected at both ends to improve ash discharge efficiency and reduce dust blockage.
[0028] The front air chamber 1 and the rear air chamber 11 are respectively connected to the front air chamber inlet pipe 5 and the rear air chamber inlet pipe 7. The front air chamber inlet pipe 5 and the rear air chamber inlet pipe 7 are controlled by the inlet pipe valve 6, and the two air chambers 12 can be inflated as needed.
[0029] The bottom end face of the side support plate 4 and the intermediate partition plate 3 is an arc face matching the arc of the tank body 10, which supports and seals in the middle, improving the blowing effect. The fluidized bed 8 is divided and corresponds to the perforated plate 2 one by one, which is beneficial to the selective maintenance of the fluidized bed 8 in the later period, avoiding the whole replacement phenomenon every time a problem occurs, and reducing the maintenance cost. The air chamber 12 is provided with an ash discharge port 13 with a diameter of 100 mm at the bottom, which is controlled by a valve, and the air chamber 12 is periodically inflated and blown, and a small amount of dust in the air chamber 12 is discharged.
[0030] The perforated plate 2 at the bottom of the tank body 10 is preferably divided into four separate assemblies, and the fluidized bed 8 covering the perforated plate 2 is also divided into four pieces with the perforated plate 2. It is beneficial to the selective maintenance of the fluidized bed 8 in the later period, avoiding the whole replacement phenomenon every time a problem occurs, and reducing the maintenance cost.
[0031] The above describes the utility model and its embodiments in a schematic manner, which is not restrictive, and the drawings shown are only one of the embodiments of the utility model, and the actual structure and manufacturing steps are not limited thereto. Therefore, if a person skilled in the art is inspired thereby, without departing from the creative purpose of the utility model, similar structural modes and embodiments can be designed without creativity, which should belong to the protection scope of the utility model.
