[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In this utility model, compared with the existing multi-stage waste gas purification device, after long-term use, a large number of impurities will be attached to the internal filter screen. These impurities may cause the filter screen to be blocked, affecting the purification effect of the filter screen on waste gas. Through the cooperation of crank rocker, transmission component and striking mechanism, the mounting frame is struck, so that the striking mechanism on both sides can reciprocate to strike both sides of the mounting frame, thereby knocking off the impurities adsorbed on the filter purification layer inside the mounting frame.

Due to the overall inclined design of the device, the tapping mechanism can gradually tap the mounting frame from bottom to top during the slow entry of the mounting frame into the lower housing, thereby enhancing the shaking effect on the impurities adsorbed on the filter purification layer. Since the purification box and the lower housing are connected, and there is a certain space after the filter purification layer is installed in the mounting frame, the impurities shaken into the purification box during the gradual tapping of the mounting frame can fall into the lower housing through the same point between the purification box and the lower housing, and roll into the discharge hopper connected to the lower housing. This facilitates the subsequent processing of the impurities shaken into the lower housing by the staff and ensures the quantity of impurities inside the lower housing. Attached Figure Description

[0028] To make the utility model's objectives, features, and advantages more apparent and understandable, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of the present utility model, and not all embodiments.

It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.

[0030] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] like Figures 1-5As shown, this utility model embodiment provides a multi-stage waste gas purification device, including a purification box 1, an upper shell 2, a slide rail 3, a rack 4, an adjustment mechanism, a mounting frame 5, a filter purification layer 6, a lower shell 7, a crank rocker 8, a transmission component, and a striking mechanism. Compared with existing multi-stage waste gas purification devices, after prolonged use, a large amount of impurities accumulate on the internal filter screen, which may cause clogging and affect the filter's purification effect on waste gas. In this embodiment, the crank rocker 8, the transmission component, and the striking mechanism work together to strike the mounting frame 5, allowing the striking mechanisms on both sides to reciprocate and knock off the impurities adsorbed on the filter purification layer 6 inside the mounting frame 5. The reciprocating striking mechanism accelerates the shaking off of impurities adsorbed on the filter purification layer 6, allowing the impurities to be quickly shaken off into the lower shell 7, reducing the clogging of the filter purification layer 6 by impurities. The probability of blockage is reduced, ensuring the purification effect of the filter layer 6 on the exhaust gas. Through the cooperation of the slide rail 3, rack 4 and adjustment mechanism, the position of the mounting frame 5 and the filter layer 6 can be adjusted, allowing the mounting frame 5 and the filter layer 6 to slowly enter the lower housing 7. Due to the overall inclined design of the device, the tapping mechanism can gradually tap the mounting frame 5 from bottom to top during the slow entry of the mounting frame 5 into the lower housing 7, thereby enhancing the shaking effect of the impurities adsorbed on the filter layer 6. Since the purification box 1 and the lower housing 7 are connected, and there is a certain space after the mounting frame 5 is installed with the filter layer 6, the impurities that fall into the purification box 1 when the mounting frame 5 is gradually tapped can fall into the lower housing 7 through the same point of the purification box 1 and the lower housing 7, and roll into the discharge hopper connected to the lower housing 7. This facilitates the subsequent processing of the impurities shaken out of the lower housing 7 by the staff, ensuring the quantity of impurities inside the lower housing 7.

[0032] like Figure 1 and Figure 3 As shown, the upper housing 2 is installed on the upper side of the purification box 1. A slide rail 3 is installed on one side of the inner wall of the upper housing 2. The slide rail 3 is I-shaped and can limit the sliding of the sliding plate 101, thus ensuring the stability of the sliding plate 101 when sliding. Multiple racks 4 are installed on the other side of the inner wall of the upper housing 2. The adjustment mechanism is slidably connected to the slide rail 3. The lower side of the adjustment mechanism is connected to the mounting frame 5 through the connecting column. Sealing gaskets are provided on both the upper and lower sides of the mounting frame 5. The sealing gaskets are used to seal the connection between the purification box 1 and the upper housing 2 and the lower housing 7. Square blocks are installed on both sides of the inner wall of the purification box 1. Square grooves are opened on both sides of the mounting frame 5. The width of the square grooves is adapted to the width of the square blocks. The square blocks can limit the mounting frame 5 through the square grooves, thus ensuring the stability of the mounting frame 5 when moving. A filter purification layer 6 is provided inside the mounting frame 5, such as... Figure 4 As shown, the adjustment mechanism includes a sliding plate 101, a rotating shaft 102, and a transmission gear 103. Two spring positioning pins 9 are provided on one side of the upper housing 2. Positioning slots are provided on one side of both the upper housing 2 and the sliding plate 101. The inner diameter of the positioning slot is adapted to the diameter of the insertion end of the spring positioning pin 9. The spring positioning pin 9 can be inserted and positioned by the positioning slot, thereby ensuring the stability of the adjustment mechanism inside the upper housing 2. The cooperation of the slide rail 3, the rack 4, and the adjustment mechanism can adjust the position of the mounting frame 5 and the filter purification layer 6, thereby realizing the replacement of the position of the mounting frame 5 and the filter purification layer 6 inside the purification box 1 and the lower housing 7. During the position replacement process, the mounting frame 5 can be gradually struck from bottom to top by two sets of striking mechanisms.

[0033] like Figure 1 and Figure 5 As shown, the lower housing 7 is installed on the lower side of the purification box 1 and communicates with the purification box 1 through an opening. The crank rocker arm 8 is rotatably installed on the lower side of the lower housing 7 through two mounting seats. One of the two mounting seats is provided with a driving component for driving the crank rocker arm 8 to rotate. The crank rocker arm 8 is connected to two sets of striking mechanisms through two sets of transmission components. The transmission components are composed of a U-shaped rod and a connecting plate. The U-shaped rod is connected to the striking mechanism, and the connecting plate is sleeved on the U-shaped rod and the crank rocker arm 8. The striking mechanism includes a mounting plate 201, a transmission plate 202, and a striking post 203. Multiple movable openings are provided on both sides of the lower housing 7. The inner diameter of the movable openings is adapted to the outer diameter of the striking post 203. When the striking post 203 strikes the mounting frame 5, the striking post 203 moves inside the movable openings. A buffer pad is installed at the inner end of the 3. The buffer pad can buffer the impact between the striking post 203 and the mounting frame 5, and avoid the impact between the striking post 203 and the mounting frame 5. Multiple guide posts 10 are installed on both sides of the lower housing 7. The transmission plate 202 is sleeved on the guide post 10. The guide post 10 can limit the transmission plate 202, thereby ensuring the stability of the transmission plate 202 when it moves. A limit plate is installed at the outer end of the guide post 10. The limit plate can block and limit the transmission plate 202 sleeved on the guide post 10, thereby avoiding the probability of the transmission plate 202 detaching from the guide post 10. The cooperation of the crank rocker 8, the transmission component and the striking mechanism can knock off the impurities adsorbed on the filter purification layer 6 inside the mounting frame 5, so that the impurities can be shaken off into the lower housing 7.

[0034] Working principle:

[0035] When it is necessary to clean the impurities adsorbed on the filter purification layer 6, the operator pulls the spring positioning pin 9 to release the positioning between the upper housing 2 and the sliding plate 101. After release, the forward and reverse motor located inside the adjustment mechanism is started. The forward and reverse motor drives the rotating shaft 102 to rotate, and the rotating shaft 102 drives the transmission gear 103 to crawl downward along the rack 4. The transmission gear 103 drives the sliding plate 101 to slide downward along the slide rail 3 through the rotating shaft 102. The sliding plate 101 drives the mounting frame 5 to move downward through the connecting column. The mounting frame 5 causes the filter purification layer 6 to fall into the lower housing 7. After the movement, the forward and reverse motor located on the mounting base is started. The forward and reverse motor drives the crank rocker arm 8 to rotate. The crank rocker arm 8 drives the mounting plate 201 to move back and forth through the transmission component. The mounting plate 201 drives the striking column 203 to move back and forth through the transmission plate 202. The striking column 203 strikes the mounting frame 5 from bottom to top, which knocks off the impurities adsorbed on the filter purification layer 6, thereby cleaning the impurities adsorbed on the filter purification layer 6. After cleaning, the staff uses the adjustment mechanism to drive the mounting frame 5 and the filter purification layer 6 back to their original positions. After returning to their original positions, because the lower shell 7 is set at an inclination, the impurities shaken into the lower shell 7 will slide into the discharge hopper and then be sucked into the corresponding position by the external suction equipment.

[0036] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
