DETAILED DESCRIPTION

[0025] In order to make the purpose, technical scheme and advantages of the utility model more clear, the technical scheme in the utility model will be described clearly and completely in combination with the drawings in the utility model below. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the utility model.

[0026] The utility model will be described in further detail below in combination with the drawings.

[0027] Referring to Figure 1 As shown in the figure, the small-diameter inert gas protection sub-chamber dust collector comprises a flower plate 1, a cylinder 2, a flange 3, a sealing ring 4, an end cover 5, is divided into sub-chamber ①, sub-chamber ② and sub-chamber ③ by a clean gas chamber partition 6 and an upper partition 7. Each sub-chamber is provided with an exhaust port, and a cylinder 9 is installed on the exhaust port. The cylinder 9 is controlled by a solenoid valve to stretch and retract at regular time intervals, so as to realize the opening and closing of the exhaust port.

[0028] The small-diameter inert gas protection sub-chamber dust collector has a small-diameter flange 3, a short and rigid flange separation rod 8, so that the end face of the flange 3 is easy to machine; the sealing ring in the middle of the upper and lower separation rods can be compressed, and the sealing effect basically meets the use requirements. After the exhaust port is closed, there is no upward airflow in the filter bag belonging to the sub-chamber, and the pulse valve works to clean the filter bag, so that the cleaning airflow is not hindered by the upward airflow, and the small-diameter inert gas protection sub-chamber dust collector is completely cleaned.

[0029] However, when the inert gas protection sub-chamber dust collector is enlarged in diameter, the diameter of the flange 3 used is large, the flange separation rod 8 is long, and the diameter is large during machining, so that the end face of the flange 3 is difficult to turn and the manufacturing cost is high, and the sealing ring between the flange separation rods cannot be compressed, resulting in poor sealing of each sub-chamber. The result of poor sealing is that even if the exhaust port of the sub-chamber is closed, the filter bag belonging to the sub-chamber is still subjected to a strong suction due to the negative pressure of the adjacent sub-chamber, so that there is still a strong upward airflow in the filter bag, and the cleaning airflow is hindered by the upward airflow when the pulse pipe works, so that the filter bag cannot be truly cleaned offline, and the cleaning is not complete.

[0030] Referring to Figure 2 , Figure 3As shown, the improved large-diameter inert gas protection sub-chamber dust collector comprises a flower plate 1, a cylinder 2, a flange 3, a sealing ring 4, and a head 5.

The improved large-diameter inert gas protection sub-chamber dust collector comprises sub-chambers ①, ②, ③, ④, ⑤, ⑥, and ⑦. The inner cover is the top of the sub-chamber. The cylinder cooperates with the head to provide a containing space. The flower plate is provided with through holes to facilitate the upward airflow. The flange cooperates with the sealing ring to connect the head and the cylinder. The partition plate separates the large chamber into small chambers. The inner cover support plate, the inner cover support arc, and the cover sealing gasket cooperate to seal. There is a cover sealing gasket above the sealing beam. The flange separation rod 8 on the flange 3 of the small-diameter inert gas protection sub-chamber dust collector is removed and replaced by the sealing beam 13. The sealing beam 13 has good rigidity and does not bend, thereby ensuring that the sub-chamber sealing meets the design requirements. The improved large-diameter inert gas protection sub-chamber dust collector has good sub-chamber sealing through the improvement of the equipment structure. After the sub-chamber exhaust port is closed, there is no upward airflow in the filter bag belonging to the sub-chamber. The pulse tube works without resistance, the dust cleaning effect is good, and the offline dust cleaning effect is completely achieved.

[0031] In addition, the flower plate 1 is arranged inside the cylinder 2. The cylinder 2 is connected with the head 5 through the flange 3. The head 5 is arranged above the cylinder 2.
