Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

At the same time, by setting a plurality of longitudinal first exhaust fans, the original horizontal smoke extraction can be changed into longitudinal flue gas, so that the dust removal effect on the flue gas can be better. At the same time, by setting the filter plate 5, the accumulation of too much dust on the first exhaust fan can be avoided.

[0031] The side surface of the first spring 1206 away from the partition board 1205 is fixedly connected with the connection box 1201, a top block 1207 is fixedly connected to the side surface of the partition board 1205 away from the first spring 1206, the top block 1207 is connected through the clamping rod 1204, a stabilizing rod 1208 is connected through the middle of the top surface of the sliding block 1202, a second spring 1209 is sleeved on the surface of the stabilizing rod 1208, the top surface of the second spring 1209 is fixedly connected with the connection box 1201, the bottom surface of the second spring 1209 is fixedly connected with the sliding block 1202, a push rod 1210 is fixedly connected to the middle of the bottom surface of the sliding block 1202, the push rod 1210 is connected through the connection box 1201, the clamping rod 1204 is connected through the connection box 1201, and the sliding block 1202 is in fit connection with the top block 1207, as Figure 4 , 6As shown, by pushing the push rod 1210, the push rod 1210 can drive the movement of the sliding block 1202. Through the movement of the sliding block 1202, the top block 1207 moves along with the movement of the sliding block 1202. At the same time, the top block 1207 is also pushed by the first spring 1206, so that one side of the top block 1207 is always in close contact with one side of the sliding block 1202. Along with the movement of the top block 1207, the movement of the latch rod 1204 can be driven, so that the latch rod 1204 is separated from the card slot 16, which facilitates the staff to quickly disassemble and clean the first filter screen 15 irregularly, thus preventing the first filter screen 15 from being blocked. At the same time, the elastic force of the first spring 1206 is less than the elastic force of the second spring 1209, which facilitates the sliding block 1202 to squeeze the top block 1207, so that the movement of the latch rod 1204 can be driven, and the latch rod 1204 is re-engaged with the card slot 16. Both the first spring 1206 and the second spring 1209 are rubber composite springs in the prior art.

[0032] On both sides of the inside of the ferrule 9, moving grooves 13 are symmetrically opened. A moving block 14 is slidably connected inside the moving groove 13. On the surface of one side of the moving block 14 away from the moving groove 13, a first filter screen 15 is fixedly connected. On both sides of the first filter screen 15, card slots 16 are symmetrically opened. The card slots 16 are engaged with the latch rods 1204. As Figure 2 shown, through the engagement between the card slot 16 and the latch rod 1204, the disassembly of the first filter screen 15 can be more convenient. At the same time, thinner sealing gaskets are installed on both sides of the first filter screen 15. After the first filter screen 15 completely enters the inside of the ferrule 9, the sealing gaskets on both sides of the outer wall of the first filter screen 15 are in close contact with the ferrule 9, so as to achieve the sealing effect and avoid the occurrence of smoke leakage.

[0033] On both sides of the underground flue 11 near the top, sliding grooves 17 are symmetrically opened. A second filter screen 18 is slidably connected inside the sliding grooves 17. On both sides of the second filter screen 18, limiting grooves 19 are symmetrically opened. A limiting rod 20 is engaged and connected inside the limiting grooves 19. On the surface of one side of the limiting rod 20 away from the limiting groove 19, a sliding rod 21 is penetrated and connected. A third spring 22 is sleeved on the surface of one side of the sliding rod 21. One side surface of the third spring 22 is fixedly connected with the limiting rod 20. The other side surface of the third spring 22 is fixedly connected with the underground flue 11. The sliding rod 21 away from the third spring 22 is fixedly connected with the underground flue 11. The limiting rod 20 penetrates and is connected with the underground flue 11. As Figure 5As shown in the figure, by pulling the limit rod 20, the limit rod 20 slides on the sliding rod 21, so that the third spring 22 undergoes a tensile deformation. By pulling the limit rod 20, after the limit rod 20 is separated from the limit groove 19, it is convenient to quickly disassemble and replace the second filter screen 18 blades that have been used for a long time, so as to facilitate better secondary filtration of the flue gas. At the same time, when installing the second filter screen 18, after placing the second filter screen 18 inside the chute 17, by loosening the limit rod 20, the limit rod 20 slides and resets on the sliding rod 21 under the action of the third spring 22, so that the limit rod 20 is engaged with the limit groove 19 again, thus completing the installation of the second filter screen 18, which can improve the work efficiency of the staff. At the same time, the third spring 22 is a tensile spring, and the second filter screen 18 is composed of a dust-proof net and a breathable sponge pad. The breathable sponge pad is located below the dust-proof net, and the dust-proof net and the breathable sponge pad are bonded by a magic tape.

[0034] Working principle: Before using this ladle dust collection device, it is necessary to first check the overall situation of the device to ensure that it can work normally. According to Figure 1 - Figure 6As shown in the figure, when the first filter screen 15 needs to be disassembled, first, by pushing the push rod 1210, the push rod 1210 can drive the movement of the sliding block 1202. Through the movement of the sliding block 1202, the top block 1207 moves along with the movement of the sliding block 1202. At the same time, the top block 1207 is also pushed by the first spring 1206, so that one side of the top block 1207 is always in close contact with one side of the sliding block 1202. Along with the movement of the top block 1207, the movement of the clamping rod 1204 can be driven, so that the clamping rod 1204 is separated from the clamping groove 16, which facilitates the staff to quickly disassemble and clean the first filter screen 15 at irregular intervals, thus preventing the first filter screen 15 from being blocked. At the same time, during installation, after the moving block 14 on the first filter screen 15 is engaged with the moving groove 13 on the ferrule 9, by pushing the first filter screen 15, the first filter screen 15 moves. After the first filter screen 15 completely enters the ferrule 9, by loosening the push rod 1210, the sliding block 1202 returns to its original position under the action of the second spring 1209. As a result, the sliding block 1202 squeezes the top block 1207, causing the top block 1207 to squeeze the partition plate 1205, resulting in the descent of the partition plate 1205. At the same time, the elastic force of the first spring 1206 is less than the elastic force of the second spring 1209, which facilitates the sliding block 1202 to squeeze the top block 1207, driving the movement of the clamping rod 1204, so that the clamping rod 1204 is re-engaged with the clamping groove 16, completing the installation of the first filter screen 15. At the same time, thinner gaskets are installed on both sides of the first filter screen 15. After the first filter screen 15 completely enters the ferrule 9, the gaskets on both sides of the outer wall of the first filter screen 15 are in close contact with the ferrule 9, achieving a sealing effect and avoiding smoke leakage.

[0035] Secondly, by pulling the limit rod 20, the limit rod 20 slides on the slide rod 21, causing the third spring 22 to undergo tensile deformation. By pulling the limit rod 20, after the limit rod 20 is separated from the limit groove 19, it is convenient to quickly disassemble and replace the second filter screen 18 that has been used for a long time, facilitating better secondary filtration of the flue gas. At the same time, when installing the second filter screen 18, after placing the second filter screen 18 in the chute 17, by loosening the limit rod 20, the limit rod 20 slides and resets on the slide rod 21 under the action of the third spring 22, so that the limit rod 20 is re-engaged with the limit groove 19, completing the installation of the second filter screen 18 and improving the work efficiency of the staff.

[0036] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
