Since the device shell is usually a one-piece design, it is very cumbersome, time-consuming and laborious to clean.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A flue gas absorption device for ferromolybdenum roasting includes a base plate and hydraulic cylinders. Two hydraulic cylinders are fixedly mounted on both sides of the upper surface of the base plate. A fixed shell is provided on the upper side of the base plate.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. This utility model uses a water pump to draw the purification liquid inside the fixed shell into the hollow plate, and then sprays it down from multiple spray heads, which can purify the flue gas inside the fixed shell. At the same time, multiple alternating fixed and movable baffles can prolong the time for the flue gas to pass through the fixed shell, so that the flue gas is purified more thoroughly.

[0017] 2. In this utility model, the piston rods of the hydraulic cylinders on both sides extend, causing the fixed shell to move upward.

The piston rod ends of the hydraulic cylinders 2 are fixedly connected to the fixed shell 3. An inlet pipe 7 and an outlet pipe 8 are fixedly mounted on both sides of the fixed shell 3, respectively. An opening is provided at the bottom of the fixed shell 3, and a sealing plate 11 is rotatably mounted inside the opening. A sealing gasket is provided on the outer wall of the sealing plate 11 to improve the sealing performance between the sealing plate 11 and the fixed shell 3. Multiple fixed partitions 6 are fixedly mounted sequentially from left to right on the upper inner wall of the fixed shell 3. Movable partitions 18 are provided between each part, with the lower side of the movable partitions 18 abutting against the upper surface of the sealing plate 11. A hollow plate 4 is fixedly installed on the top of the fixed shell 3, and multiple spray heads 5 are fixedly installed on the lower side of the hollow plate 4. The lower ends of the multiple spray heads 5 extend into the interior of the fixed shell 3. A water pump 9 is fixedly installed on the inner wall of one side of the lower end of the fixed shell 3. A connecting pipe 10 is fixedly connected to the outlet of the water pump 9. One end of the connecting pipe 10 is connected to the hollow plate 4. Sealing rings are provided at both ends of the connecting pipe 10 and the corresponding connection parts of the fixed shell 3 and the hollow plate 4 to improve the sealing performance of the connection between the connecting pipe 10 and the fixed shell 3 and the hollow plate 4.

[0027] Reference Figure 1-3 The upper surface of the base plate 1 is provided with a transmission mechanism on both sides to drive the sealing plate 11 to rotate. The transmission mechanism includes a gear 13 and a rack 14. The lower end of the fixed shell 3 is provided with rotating rods 12 on both sides. One end of the rotating rod 12 is fixedly connected to the side wall of the sealing plate 11. The gear 13 is fixedly sleeved on the outer end of the rotating rod 12. The rack 14 is meshed on one side of the gear 13. One end of the rack 14 is fixedly connected to the base plate 1.

[0028] Reference Figure 1-3 The top inner wall of the fixed shell 3 is provided with a reset mechanism to keep the movable partition 18 stable. The reset mechanism includes a stop block 16 and a spring 17. The movable partition 18 has a cavity inside. The stop block 16 is slidably disposed inside the cavity. A connecting rod 15 is fixedly disposed on the upper side of the stop block 16. The upper end of the connecting rod 15 extends to the outer side of the cavity and is fixedly connected to the inner wall of the fixed shell 3. The spring 17 is fixedly disposed on the lower side of the stop block 16. The other end of the spring 17 is fixedly connected to the inner wall of the cavity.

A movable rod 20 is movably sleeved inside the fixed tube 19. The upper end of the movable rod 20 is fixedly connected to the bottom of the fixed shell 3, so that the fixed shell 3 can move stably.

[0030] In this invention, during use, the water pump 9 draws the purification liquid inside the fixed shell 3 into the hollow plate 4, and then sprays it down from multiple spray nozzles 5, which can purify the flue gas inside the fixed shell 3. At the same time, multiple alternating fixed baffles 6 and movable baffles 18 can prolong the time for the flue gas to pass through the fixed shell, so that the flue gas is purified more thoroughly. When cleaning the dirt accumulated on the sealing plate 11, the piston rods of the hydraulic cylinders 2 on both sides extend, which causes the fixed shell 3 to move upward. At this time, the gear 13 moves relative to the fixed rack 14, which causes the gear 13 to rotate, thereby causing the gear 13 to drive the rotating rod 12 to rotate. The rotating rod 12 drives the sealing plate 11 to rotate. During this process, the sealing plate 11 will squeeze the movable baffle 18 upward, which can flip the sealing plate 11, making it convenient to clean the dirt accumulated on the sealing plate 11.
