Description

Technical Field

[0001] This utility model relates to the field of medium-frequency melting furnace technology, specifically a dust removal device for the dust guide pipe of a medium-frequency melting furnace. Background Technology

[0002] The dust guide pipe of the medium frequency melting furnace is a pipe connecting the melting furnace and the dust collector. Its main function is to guide and transport the smoke and dust generated during the melting process, ensuring that the smoke and dust can smoothly enter the dust collector for purification. Then, the dust collector is used to clean the inside of the dust guide pipe to reduce the dust residue inside the dust guide pipe.

[0003] When in use, because the dust guide tube is set horizontally, some dust will accumulate inside the dust guide tube, which will reduce the dust discharge effect of the dust guide tube.

[0004] To overcome the above-mentioned defects, the prior art (Chinese patent with publication number CN220437167U, application date 2024-02-02) provides a dust removal device for a medium-frequency melting furnace. The cleaning assembly includes a mounting plate, a movable plate, and a push rod. A dust hood, a pipe body, an S-shaped connecting pipe, a dust guide pipe, and an induced draft fan are sequentially connected. The mounting plate is fixedly connected to the S-shaped connecting pipe, located on the outside of the S-shaped connecting pipe. The push rod is slidably connected to the mounting plate, passing through the mounting plate and into the S-shaped connecting pipe. The movable plate is fixedly connected to the push rod, located on the inside of the S-shaped connecting pipe. When dust accumulates in the dust guide pipe, the push rod can be pushed, causing the movable plate to move in the horizontal section of the dust guide pipe, thereby pushing away the dust accumulated in the horizontal section of the dust guide pipe to prevent dust accumulation and blockage of the dust guide pipe.

[0005] The aforementioned mechanism uses a movable plate to move inside the dust guide tube, thereby promoting the horizontal discharge of smoke and dust. However, in actual use, some lighter smoke and dust will remain at the top of the dust guide tube due to electrostatic adsorption. Cleaning only the bottom of the dust guide tube will result in smoke and dust residue. Utility Model Content

[0006] The purpose of this utility model is to provide a dust removal device for the dust guide pipe of a medium-frequency melting furnace, so as to solve the problem mentioned in the background art that some lighter dust will still be adsorbed by electrostatics at the top of the inside of the dust guide pipe, and that cleaning only the bottom of the inside of the dust guide pipe will result in dust residue.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a dust removal device for a medium-frequency melting furnace dust guide pipe, comprising a fixed rod, a dust guide pipe body being provided on the right side of the fixed rod, and a pneumatic telescopic rod being installed on the left side of the fixed rod by bolts, the output end of the pneumatic telescopic rod extending into the interior of the fixed rod, and a rotating rod being installed on the output end of the pneumatic telescopic rod by a threaded rod;

[0008] The outer side of the rotating rod is provided with a limiting groove, and the inner side of the limiting groove is provided with a cleaning mechanism for cleaning the dust inside the dust guide tube body. The cleaning mechanism includes a cleaning brush, and the cleaning brush is rotatably connected to the inside of the limiting groove. A counterweight is installed on the right side of the cleaning brush.

[0009] The left side inside the fixed rod is rotatably connected to a rotating seat, and the inside of the fixed rod is equipped with an exhaust mechanism for cleaning residual smoke and dust inside the dust guide pipe body.

[0010] Furthermore, the counterweight is disposed inside the limiting groove, and the limiting groove is distributed at equal angles on the outside of the rotating rod.

[0011] Furthermore, the exhaust mechanism includes an elastic airbag, which is disposed inside a fixed rod outside the threaded rod. A fixed block is disposed on the right side inside the fixed rod, and a rotating plate is disposed on the left side of the fixed block. The right side of the elastic airbag is in contact with the rotating plate. An air inlet pipe is disposed inside the elastic airbag. A fixed groove is opened inside the threaded rod and the rotating rod. The air inlet pipe is connected to the fixed groove. Air outlet holes are opened at equal intervals on the outer side of the rotating rod.

[0012] Furthermore, the output end of the pneumatic telescopic rod extends to one side inside the fixed rod and is rotatably connected to a rotating seat. A threaded rod is installed on the right side of the rotating seat, and a ball bearing matching the threaded rod is provided inside the fixed block. The right side of the threaded rod is connected to the fixed rod through a rotating shaft, and the right side of the threaded rod is fixedly connected to the rotating rod.

[0013] Furthermore, the positions of the air outlet and the limiting groove correspond to each other, and the air outlets are distributed at equal angles on the outer side of the rotating rod.

[0014] Furthermore, a connecting tube is provided on the left side of the elastic airbag, and the connecting tube passes through and extends to one side of the rotating seat.

[0015] Furthermore, a fixing hole is provided on the left side of the outside of the fixing rod, and the fixing holes are distributed at equal angles on the outside of the fixing rod.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. Through the cooperation of the threaded rod and the ball, the threaded rod rotates, which in turn drives the rotating rod to rotate. The cleaning brush and counterweight set inside the limiting groove are thrown out and the angle changes due to the rotation, so that the edge of the counterweight contacts the inner wall of the dust guide pipe body, thereby cleaning the residual dust in the horizontal part inside the dust guide pipe body.

[0018] Furthermore, the cleaning brush can balance and adjust the angle of the counterweight, so that when not in use, the counterweight can be deflected by the counterweight of the cleaning brush to achieve storage, thus preventing the counterweight from blocking the conveying of dust when the dust guide tube is working.

[0019] Furthermore, the ball bearings and the spiral groove on the outside of the threaded rod are matched with each other, so that the threaded rod is driven and rotated. The rotation of the threaded rod will drive the rotating rod to rotate synchronously. By using the rotation of the threaded rod to drive the rotating rod to rotate, the cleaning brush inside the limiting groove is thrown out and the dust inside the dust guide tube body is cleaned.

[0020] 2. As the threaded rod rotates, it continuously pushes outward, causing the rotating seats on both sides to rotate. Simultaneously, the continuous pushing of the threaded rod causes the rotating seats to compress the elastic airbag. The gas inside the elastic airbag enters the fixed groove through the air inlet pipe. By utilizing the cooperation between the fixed groove and the air outlet, the gas inside the elastic airbag can be discharged, and the gas can clean the residual dust on the inner side wall of the dust guide tube body.

[0021] Furthermore, through the cooperation of the exhaust mechanism and the cleaning mechanism, the dust in different locations inside the dust guide pipe can be cleaned multiple times, thereby effectively reducing dust residue and preventing dust accumulation from affecting the dust guide efficiency of the dust guide pipe.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0030] Example 1:

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4 The technical solution shown addresses the issue that some lighter dust particles remain at the top of the dust guide tube due to electrostatic adsorption, resulting in dust residue if only the bottom of the dust guide tube is cleaned. The dust removal device for the dust guide tube of this medium-frequency melting furnace discloses a cleaning mechanism, including a fixed rod 2. A dust guide tube body 14 is located on the right side of the fixed rod 2, and a pneumatic telescopic rod 1 is bolted to the left side of the fixed rod 2. The output end of the pneumatic telescopic rod 1 extends into the interior of the fixed rod 2. A rotating rod 4 is mounted to the output end of the pneumatic telescopic rod 1 via a threaded rod 3. A limiting groove 5 is formed on the outer side of the rotating rod 4, and a cleaning mechanism for cleaning the dust inside the dust guide tube body 14 is provided inside the limiting groove 5. The cleaning mechanism includes a cleaning brush 6, which is rotatably connected to the inside of the limiting groove 5. A counterweight 15 is installed on the right side of the cleaning brush 6, and the counterweight 15 is located inside the limiting groove 5. The limiting groove 5 is evenly distributed on the outer side of the rotating rod 4.

[0032] In this example, the output end of the pneumatic telescopic rod 1 can move the threaded rod 3 and the rotating rod 4 into the interior of the dust guide pipe body 14. Through the cooperation of the threaded rod 3 and the ball 9, the threaded rod 3 rotates, thereby driving the rotating rod 4 to rotate. The cleaning brush 6 and the counterweight 15 set inside the limiting groove 5 are thrown out and changed in angle due to the rotation, so that the edge of the counterweight 15 contacts the inner wall of the dust guide pipe body 14, thereby cleaning the residual dust in the horizontal part inside the dust guide pipe body 14.

[0033] Furthermore, the cleaning brush 6 can adjust the weight and angle of the counterweight 15, so that when not in use, the counterweight 15 can be deflected by the weight of the cleaning brush 6 to achieve storage, thus preventing the counterweight 15 from obstructing the conveying of dust during the operation of the dust guide pipe body 14.

[0034] Example 2:

[0035] like Figure 3 , Figure 5 and Figure 6 The technical solution shown addresses the problem of insufficient cleaning caused by the varying overall length of the dust guide pipe body 14: the dust removal device for the dust guide pipe of the medium-frequency melting furnace discloses a threaded rod 3 and ball bearings 9. The output end of the pneumatic telescopic rod 1 extends to one side inside the fixed rod 2 and is rotatably connected to a rotating seat 16. The threaded rod 3 is installed on the right side of the rotating seat 16, and the fixed block 17 is equipped with ball bearings 9 that match the threaded rod 3. The right side of the threaded rod 3 is connected to the fixed rod 2 via a rotating shaft, and the right side of the threaded rod 3 is fixedly connected to the rotating rod 4.

[0036] In this example, when the output end of the pneumatic telescopic rod 1 pushes the threaded rod 3, the ball 9 and the spiral groove on the outside of the threaded rod 3 are matched, so that the threaded rod 3 is driven and rotated. The rotation of the threaded rod 3 will drive the rotating rod 4 to rotate synchronously. By using the rotation of the threaded rod 3 to drive the rotating rod 4 to rotate, the cleaning brush 6 inside the limiting groove 5 is thrown out and the dust inside the dust guide tube body 14 is cleaned.

[0037] By repeatedly extending and retracting the output end of the pneumatic telescopic rod 1, the threaded rod 3 is rotated, thereby cleaning the inside of the dust guide pipe body 14 repeatedly, which can effectively reduce the residue of smoke and dust inside the dust guide pipe body 14.

[0038] Example 3:

[0039] like Figure 1 , Figure 2 , Figure 3 and Figure 5The technical solution shown addresses the problem of dust residue adsorbed at the top of the dust guide pipe body 14. The dust removal device for the dust guide pipe of this medium-frequency melting furnace discloses an exhaust mechanism. A rotating seat 16 is rotatably connected to the left side inside the fixed rod 2. The fixed rod 2 is equipped with an exhaust mechanism for cleaning residual dust inside the dust guide pipe body 14. The exhaust mechanism includes an elastic airbag 10, which is located inside the fixed rod 2 outside the threaded rod 3. A fixing block 17 is located on the right side inside the fixed rod 2, and a rotating plate 18 is located on the left side of the fixing block 17. The right side of the elastic airbag 10 is in contact with the rotating plate 18. An air inlet pipe 11 is provided on the inner side of the elastic airbag 10. A fixing groove 7 is provided inside the threaded rod 3 and the rotating rod 4. The air inlet pipe 11 is connected to the fixing groove 7. An air outlet 8 is provided at equal intervals on the outer side of the rotating rod 4. The positions of the air outlet 8 and the limiting groove 5 correspond to each other. The air outlet 8 are distributed at equal angles on the outer side of the rotating rod 4. A connecting pipe 12 is provided on the left side of the elastic airbag 10. The connecting pipe 12 passes through and extends to one side of the rotating seat 16. A fixing hole 13 is provided on the left side of the outer side of the fixing rod 2. The fixing holes 13 are distributed at equal angles on the outer side of the fixing rod 2.

[0040] In this example, the threaded rod 3 continuously pushes outwards during rotation, causing the rotating seats 16 on both sides to rotate. Simultaneously, the continuous pushing of the threaded rod 3 causes the rotating seats 16 to compress the elastic airbag 10. The gas inside the elastic airbag 10 enters the fixed groove 7 through the air inlet pipe 11. By utilizing the cooperation between the fixed groove 7 and the air outlet 8, the gas inside the elastic airbag 10 can be discharged, allowing the gas to clean the residual dust on the inner side wall of the dust guide pipe body 14. Both the air inlet pipe 11 and the connecting pipe 12 are equipped with one-way air inlet valves, ensuring that the device does not interfere with each other during repeated air intake and exhaust, thus enabling more stable gas discharge and achieving auxiliary dust removal.

[0041] By cooperating with the exhaust mechanism and the cleaning mechanism, the smoke and dust in different locations inside the dust guide pipe body 14 can be cleaned multiple times, thereby effectively reducing smoke and dust residue and preventing smoke and dust accumulation from affecting the dust guide efficiency of the dust guide pipe body 14.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
