[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1-11 This utility model provides a technical solution: a high-efficiency boiler dust removal device, including a base plate 1, a boiler body 2, and a fixing pipe 3. The fixing pipe 3 is fixed to the outer wall of the boiler body 2 and communicates with its inner cavity. The boiler body 2 is installed on the top surface of the base plate 1. An exhaust pipe 4 is provided on the right side of the fixing pipe 3 and is tightly fitted therewith. Inside the exhaust pipe 4, there is a movable frame 5 and an installation frame 6 that are slidably connected to its circumferential inner wall and are arranged from left to right. A filter plate 7 is installed on the circumferential inner wall of the movable frame 5, and an activated carbon plate 8 is tightly attached to the circumferential inner wall of the installation frame 6. A suction fan 10 located on the right side of the installation frame 6 is installed on the circumferential inner wall of the exhaust pipe 4. The device also includes:

[0034] The limiting mechanism 9, installed on the outer wall of the boiler body 2, is used to limit the exhaust pipe 4. The limiting mechanism 9 includes a fixed plate 91 fixed to the outer wall of the boiler body 2 near the right end, an L-shaped vertical plate 92 fixed to the top surface of the fixed plate 91, a rotating column 93 rotatably connected to the horizontal end of the vertical plate 92, a rotating roller 94 rotatably connected to the top surface of the fixed plate 91, a screw 95 coaxially fixed between the rotating roller 94 and the rotating column 93, a movable plate 96 slidably connected to the right side surface of the vertical end of the vertical plate 92 and threadedly connected to the screw 95, a limiting rod 98 fixed to the top surface of the movable plate 96 for limiting the exhaust pipe 4, a rotating rod 99 coaxially fixed to the bottom surface of the rotating roller 94, and a driving rod mounted on the bottom surface of the fixed plate 91. The motor 912, which rotates the rotating rod 99, tightly connects the collection pipe of the external waste gas collection device to the exhaust pipe 4. Through the setting of the fixed pipe 3, the exhaust pipe 4, and the suction fan 10, the waste gas generated by the boiler body 2 during operation can be collected, thereby achieving the effect of dust removal. By setting the moving frame 5, the mounting frame 6, the filter plate 7, and the activated carbon plate 8, the waste gas generated during the production process can be filtered and purified. By setting the limiting mechanism 9, the exhaust pipe 4 can be limited, thereby facilitating the disassembly of the exhaust pipe 4, and thus facilitating the disassembly and cleaning of the filter plate 7 and the activated carbon plate 8. It also facilitates the disassembly and replacement of the filter plate 7 and the activated carbon plate 8, thereby enabling the entire device to maintain a state of high-efficiency dust removal.

[0035] In this embodiment, the limiting mechanism 9 also includes two sprockets 910 located below the fixed plate 91 and connected by a chain 911, and a rotating shaft 913 coaxially connected to the output shaft of the motor 912. The two sprockets 910 are coaxially fixed on the outer circumference of the rotating shaft 913 and the rotating rod 99, respectively, which can smoothly drive the rotating rod 99 to rotate, and thus smoothly drive the screw 95 to rotate.

[0036] In addition, the inner circumference of the fixed pipe 3 is provided with two symmetrical slots, and the outer wall of the exhaust pipe 4 is fixed with two inserts 11 that slide into the slots on the same side of the inner wall of the fixed pipe 3. This can guide the installation of the exhaust pipe 4 and also facilitate the positioning of the exhaust pipe 4.

[0037] Furthermore, the outer circumference of the fixed tube 3 is provided with a through hole near the bottom end, which is connected to its inner cavity. The outer circumference of the exhaust pipe 4 is provided with a limiting hole that corresponds to the position and size of the through hole on the outer wall of the fixed tube 3. The limiting rod 98 passes through the through hole on the outer wall of the fixed tube 3 and slides into the limiting hole on the outer wall of the exhaust pipe 4, thereby facilitating the limiting of the exhaust pipe 4, and further facilitating the limiting of the filter plate 7, the activated carbon plate 8 and the suction fan 10.

[0038] Furthermore, the right side surface of the vertical plate end of the upright plate 92 is provided with a guide groove, and the left side surface of the movable plate 96 is fixed with a guide block 97 that is slidably connected to the guide groove on the right side surface of the vertical plate end of the upright plate 92. This can guide the movement of the movable plate 96, and thus indirectly guide the movement of the limiting rod 98.

[0039] Specifically, the bottom of the base plate 1 is fixed with an anti-slip plate 14 that matches its shape, and the thickness of the anti-slip plate 14 is 2-4cm, preferably 3cm in this paper, so as to increase the friction between the entire device and the ground, thereby making the entire device more stable during operation.

[0040] It is worth noting that two sliding grooves are provided on the inner circumference of the exhaust pipe 4. Two sliding strips 12 are fixed on the outer circumference of both the moving frame 5 and the mounting frame 6, which are slidably connected to the sliding grooves on the same side of the inner circumference of the exhaust pipe 4. Several positioning blocks 13 are fixed on the inner circumference of the mounting frame 6, and the left side surface of the positioning block 13 is in close contact with the right side surface of the activated carbon plate 8. This can guide the disassembly and assembly of the moving frame 5 and the mounting frame 6, and thus indirectly guide the disassembly and assembly of the filter plate 7 and the activated carbon plate 8, while also limiting the position of the activated carbon plate 8.

[0041] It is worth noting that the limiting mechanism 9 also includes a protective box 914 fixed to the bottom surface of the fixed plate 91. The motor 912 is located inside the protective box 914, and the rotating shaft 913 passes through the bottom surface of the protective box 914, which can protect the motor 912 and thus extend the service life of the motor 912.

[0042] It is worth emphasizing that the longitudinal cross-sectional shape of the slot on the inner wall of the fixed pipe 3 is convex, and the shape of the insert 11 is convex, which matches the shape of the slot on the inner wall of the fixed pipe 3. This makes the connection between the insert 11 and the slot on the same side of the inner wall of the fixed pipe 3 more compact, thereby indirectly making the exhaust pipe 4 more stable after installation.

[0043] Finally, it should be noted that the boiler body 2, motor 912, and suction fan 10 involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the spare parts of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle in this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0044] In the specific use of this embodiment, when dust removal is required, the collection pipe of the external exhaust gas collection device is first tightly connected to the exhaust pipe 4. Then, the suction fan 10 is started through the external PLC. When the boiler body 2 is running, the suction fan 10 can suck the dust and exhaust gas inside the boiler body 2 into the fixed pipe 3. Some of the exhaust gas entering the fixed pipe 3 then enters the external collection pipe through the exhaust pipe 4. The exhaust gas entering the external collection pipe then enters the external collection device. When the boiler body 2 stops working, the suction fan 10 is turned off through the external PLC.

[0045] When cleaning or replacing filter plate 7 and activated carbon plate 8 is required, first separate the collection pipe of the external exhaust gas collection device from the exhaust pipe 4. Then, start motor 912 via external PLC. The output shaft of motor 912 rotates, driving the rotating shaft 913 connected to it to rotate. The rotating shaft 913 rotates, driving the sprocket 910 fixed on the same side to rotate. The rotation of sprocket 910 drives another sprocket 910 connected to it via chain 911 to rotate. The rotation of the other sprocket 910 drives the rotating rod 99 fixed to it to rotate. The rotation of rotating rod 99 drives the rotating column 93 fixed to it to rotate. The rotation of rotating column 93 drives the screw 95 fixed to it to rotate. The rotation of screw 95 drives the moving plate 96 threaded to it to move downward. The moving plate 96 moves under the guidance of guide block 97 and guide groove on the right side surface of vertical plate 92. The movement of moving plate 96 drives the limiting rod 98 fixed to it to limit its movement. When rod 98 moves downwards, and the limiting rod 98 is completely separated from the upper limit hole on the outer wall of exhaust pipe 4 and the through hole on the outer wall of fixed pipe 3, motor 912 is turned off by external PLC. Then, exhaust pipe 4 is pulled to the right. Under the guidance of the two inserts 11 and the two slots on the inner wall of fixed pipe 3, exhaust pipe 4 moves until the two inserts 11 are completely separated from the two slots on the inner wall of fixed pipe 3, thus completing the disassembly of exhaust pipe 4. Then, exhaust pipe 4 is placed upside down with the suction fan 10 facing upwards, so that moving frame 5 and mounting frame 6 can move downwards under the guidance of the two slide bars 12 on the same side and the two slide grooves on the inner wall of exhaust pipe 4, until moving frame 5 and mounting frame 6 are separated from exhaust pipe 4. Then, filter plate 7 and activated carbon plate 8 can be cleaned, and activated carbon plate 8 can be replaced. Conversely, the cleaned or replaced filter plate 7 and activated carbon plate 8 can be installed, and exhaust pipe 4 can also be installed.
