[0002] With the increasing demand for high-precision and high-performance forgings in industrial production, vacuum forging technology has been widely used. However, traditional dust removal methods are difficult to meet the complex composition and stringent environmental protection requirements of vacuum forging flue gas. The flue gas contains metal dust, high-temperature oxidation products, volatile organic compounds, etc., and a single dust removal method cannot achieve comprehensive and in-depth purification.

[0003] However, in existing flue gas treatment methods, impurities in the flue gas often clog the filter plates, which slows down the flue gas flow and reduces flow efficiency.

[0004] In view of this, this utility model is hereby proposed. Utility Model Content

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0024] like Figures 1 to 5 As shown, a multi-stage dust removal system for flue gas in vacuum forging includes a treatment box 1, an air inlet pipe 2 connected to the bottom of the treatment box 1, a sliding door 3 on the front side of the treatment box 1, a one-way valve 4 installed in the inner cavity of the treatment box 1 and the air inlet pipe 2, a shaped mounting plate 6 fixedly installed in the inner cavity of the treatment box 1, a slot in the middle of the shaped mounting plate 6, a collection trough 8 on the top of the shaped mounting plate 6, a connecting pipe 7 above the collection trough 8, a spray head 9 installed in the slot of the shaped mounting plate 6, a filter plate 10 installed in the inner cavity of the treatment box 1, an upper guide platform 12 and a lower guide platform 11 respectively installed on the upper and lower side walls of the filter plate 10, the upper guide platform 12 and the lower guide platform 11 being symmetrical to each other, a transmission mechanism installed on the top of the treatment box 1, the transmission mechanism being used to drive the filter plate 10 to rotate, and the transmission mechanism being used to clean the filter holes in the filter plate 10. The transmission mechanism can drive the connecting rod 21 to rotate and move vertically downward. Therefore, when the transmission mechanism drives the filter plate 10 to rotate, it can always ensure that the guide rod 23 installed at the bottom of the connecting rod 21 is inserted into the filter hole in the filter plate 10, thereby cleaning the filter hole in the filter plate 10.

[0025] In a specific embodiment, the transmission mechanism includes a servo motor 5, which is positioned above the processing box 1. A rotating rod 13 is fixedly mounted on the output end of the servo motor 5, and the rotating rod 13 movably passes through the processing box 1, with its port fixedly connected to the upper guide platform 12. In this configuration, the installation position and components of the transmission mechanism are defined.

[0026] Furthermore, a guide groove 17 is provided on the rotating rod 13. A guide slider is slidably installed in the inner cavity of the guide groove 17, and a guide sleeve 18 is fixedly installed on the guide slider. The guide sleeve 18 is sleeved on the rotating rod 13. A first sliding mechanism is provided above the guide sleeve 18. The first sliding mechanism includes a first circular groove 14, which is opened above the guide sleeve 18. Four first movable sliders 15 arranged in a circular pattern are slidably installed in the inner cavity of the first circular groove 14. A first telescopic rod 16 is provided above the four first movable sliders 15, and the other end of the four first telescopic rods 16 is provided on the inner wall of the processing box 1. In this configuration, the guide sleeve 18 can move vertically up and down.

[0027] Furthermore, a second sliding mechanism is provided on the side wall of the guide sleeve 18. The second sliding mechanism includes a second circular groove 19, which is formed on the side wall of the guide sleeve 18. Four second movable sliders 20 arranged in a circular pattern are slidably installed inside the second circular groove 19. Each of the four second movable sliders 20 has a connecting rod 21 fixedly connected to its opposite end. In this configuration, the installation position and components of the second sliding mechanism are determined.

[0028] Furthermore, multiple mounting rings 22 are fixedly installed on the four connecting rods 21. The diameter of each mounting ring 22 decreases from the outside to the inside, and the mounting rings 22 are equidistant from each other. Multiple guide rods 23 are fixedly installed at the bottom of each mounting ring 22, and each guide rod 23 is matched with the filter hole in the filter plate 10. In this configuration, the installation position of the mounting rings 22 is determined.

[0029] Furthermore, each of the four second movable sliders 20 is fixedly mounted with a second telescopic rod 24, and a fixing plate 25 is fixedly connected to the upper end of each second telescopic rod 24. The opposite side walls of each fixing plate 25 are respectively fixedly connected to the rotating rod 13. This configuration ensures that the connecting rod 13 can rotate and move up and down.

[0030] The implementation principle of a multi-stage dust removal system for flue gas in vacuum forging according to this embodiment is as follows:

[0031] First, when the flue gas enters the inner cavity of the treatment box 1 through the inlet pipe 2, the flue gas can move upward along the slot in the middle of the irregularly shaped mounting plate 6 in the treatment box 1, and then contact the lower guide platform 12 through the connecting pipe 7. At this time, the flue gas can enter the bottom perimeter of the filter plate 10, and then enter the upper part through the mesh. Since the flue gas contains impurities, the impurities can be blocked by the filter plate 10. (When the flue gas passes through the slot in the irregularly shaped mounting plate, the spray head 9 in the slot can spray water, which can treat the impurities in the flue gas. Since a one-way valve 4 is installed at the inlet pipe 2, it is ensured that the water will not flow out. At the same time, when the water outlet pipe is opened, the water can be discharged, and when the pull door 3 is opened, the one-way valve 4 can be inspected, which can prevent the one-way valve 4 from becoming blocked to a certain extent.)

[0032] At the same time, the servo motor 5 is controlled by the controller to run, so the servo motor 5 can drive the rotating rod 13 to rotate. When the rotating rod 13 rotates, it can drive the guide sleeve 18 to move vertically up and down with the assistance of the first circular groove 14, the first moving slider 15 and the first telescopic rod 16.

[0033] When the guide sleeve 18 moves vertically up and down, the connecting rod 21 can be driven to move vertically downward through the second circular slide groove 19 and the second movable slider 20. Because the second movable slider 20 has a second telescopic rod 24 fixedly installed at the bottom and the bottom end of the second telescopic rod 24 is fixedly connected to the fixing plate 25, the fixing plate 25 can drive the second movable slider 20 to rotate in the second circular slide groove 19. Therefore, the connecting rod 21 can rotate while moving vertically downward.

[0034] When the connecting rod 21 rotates and moves vertically downward, the filter plate 10 can rotate at this time, so that the guide rod 23 installed at the bottom of the connecting rod 21 can be inserted into the filter hole in the filter plate 10, thereby cleaning the filter hole in the filter plate 10.
