Description

Technical Field

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

[0002] Medium frequency furnaces are mostly used for heating bars of metals such as steel, aluminum, and copper, for pre-rolling heating, and for heating steel plates, steel pipes, and various metal blanks. When heating bars of metals such as steel, aluminum, and copper in a horizontal medium frequency furnace, a large amount of flue gas is generated. Generally, the generated flue gas is collected by an induced draft fan and enters the flue gas duct, then enters a dust collector to remove dust from the flue gas. The purified flue gas is then discharged into the atmosphere through a chimney.

[0003] The prior art, disclosed in publication number CN219624461U, discloses a novel medium-frequency furnace, including a medium-frequency heating furnace for heating metal bars such as steel, aluminum, and copper; a control cabinet connected to the bottom of the medium-frequency heating furnace for controlling the furnace; and an automatic material conveying mechanism connected to the control cabinet for automatically conveying materials into the furnace. In operation, the exhaust fan is started, and the flue gas drifting from the openings at both ends of the medium-frequency heating furnace is extracted through the smoke-collecting hoppers at both ends of the three-way pipe. The flue gas is then transported to the distribution pipe through the smoke conveying pipe. After entering the distribution pipe, the flue gas is ejected from multiple distribution holes, forming small bubbles. The stirring motor is started, driving the stirring shaft to rotate. Through the stirring blades on the shaft, the flue gas within the bubbles is thoroughly mixed with the condensate in the water tank, performing initial filtration of the particles in the flue gas and simultaneously reducing the flue gas temperature to prevent damage to the dust collector from high-temperature flue gas.

[0004] However, in the above-mentioned dust removal mechanism, the position of the flue is fixed and cannot be adjusted, which results in a limited range of flue gas absorption and reduces the dust removal effect. Therefore, a dust removal mechanism for a medium-frequency heating furnace is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a dust removal mechanism for a medium-frequency heating furnace, which has advantages such as easy position adjustment. It solves the problem that the position of the existing medium-frequency heating furnace flue is fixed and cannot be adjusted, resulting in a limited range of flue gas absorption and reduced dust removal efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a dust removal mechanism for a medium-frequency heating furnace, comprising a machine body, a medium-frequency heating furnace main body being provided on the top of the machine body, a discharge platform being provided at the outlet of the medium-frequency heating furnace main body, and a dust removal component being provided on the outer side of the discharge platform;

[0007] The dust removal assembly includes a dust extraction fan, a fixed pipe is fixedly installed at the input end of the dust extraction fan, an installation pipe is movably inserted into the inner side of the fixed pipe, a dust extraction head is fixedly connected to the end of the installation pipe near the discharge platform, and a moving mechanism is provided on the upper side of the installation pipe.

[0008] The moving mechanism includes a top plate, on which a drive motor is fixedly mounted. A lead screw is driven and connected to the output shaft of the drive motor. A threaded sleeve is threadedly connected to the outer side of the lead screw. A first vertical rod is fixedly connected to the bottom of the threaded sleeve. A second vertical rod is provided on one side of the first vertical rod. The lower end of the second vertical rod is fixedly connected to the mounting tube.

[0009] Furthermore, the dust extraction fan is located on the top of the main body of the medium-frequency heating furnace, and the dust extraction head is located above the discharge platform.

[0010] Furthermore, a column is fixedly connected to one side of the machine body, one end of the top plate is fixedly connected to the column, and a support rod is fixedly connected to the other end of the top plate. The lower end of the support rod is fixedly connected to the main body of the medium-frequency heating furnace.

[0011] Furthermore, a main gear is fixedly mounted on the output shaft of the drive motor, and a driven gear is fixedly connected to the outside of the lead screw, with the main gear and the driven gear meshing together.

[0012] Furthermore, a connecting rod is fixedly connected between the first vertical rod and the second vertical rod.

[0013] Furthermore, one end of the lead screw is connected to the column via a bearing, a guide rail is fixedly installed at the bottom of the top plate, and the end of the lead screw away from the column is connected to the outer side of the guide rail via a bearing.

[0014] Furthermore, a slider is fixedly connected to the upper end of the second vertical rod, and the slider is slidably connected to the inner side of the guide rail.

[0015] Compared with the prior art, this utility model provides a dust removal mechanism for a medium-frequency heating furnace, which has the following beneficial effects:

[0016] The dust removal mechanism of this medium-frequency heating furnace uses a combination of a dust extraction fan, a fixed pipe, an installation pipe, and a dust extraction head to extract the smoke and dust discharged from the furnace body and transport it to other dust treatment equipment. During the dust extraction process, the drive motor is activated to drive the main gear and the driven gear, which in turn drives the lead screw to rotate. The lead screw then drives the threaded sleeve to move, thereby moving the first vertical rod, the connecting rod, and the second vertical rod. This causes the installation pipe to move along the outer wall of the fixed pipe, allowing for adjustment of the position of the dust extraction head. This improves the dust removal effect and solves the problem that the position of the existing medium-frequency heating furnace's smoke hopper is fixed and cannot be adjusted, resulting in a limited range of smoke extraction and reduced dust removal efficiency.
