Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to a device for preventing the tilting of an electrolytic aluminum anode assembly medium-frequency furnace. Background Technology

[0002] In the field of aluminum electrolytic anode assembly, the intermediate frequency furnace is a key piece of equipment for smelting molten iron. Its tilting action is primarily controlled by a speed reducer, and current technology presents significant safety hazards. Specifically, existing intermediate frequency furnaces rely solely on the speed reducer for tilting and reversing, lacking additional braking or limiting devices. If the speed reducer malfunctions or there is an abnormality in the connection between the furnace body and the speed reducer (such as wear, loosening, or breakage of components) during the tilting of the 2 tons of high-temperature molten iron smelted per batch after slag removal, the furnace may suddenly lose control and tilt backward. Since the cooling water pipes of the intermediate frequency furnace are concentrated at the furnace bottom, if the uncontrolled tilting furnace spills high-temperature molten iron onto the furnace bottom, it is highly likely to scald the water pipes, causing direct contact between the cooling water and the high-temperature molten iron, triggering a violent vaporization reaction and resulting in a large-scale explosion. Such accidents not only cause devastating damage to the intermediate frequency furnace itself but also pose a serious threat to the lives of nearby operators, representing a major safety hazard. In the existing technology, the single nature of furnace body tilt control and the lack of safety protection measures have led to multiple problems for medium frequency furnaces during operation, such as molten iron spillage, water pipe damage, and explosion risks caused by uncontrolled tilting. There is an urgent need for a safety device that can effectively prevent the furnace body from tilting backward to solve the above-mentioned technical defects. Utility Model Content

[0003] The purpose of this utility model is to provide a device to prevent the tilting of an electrolytic aluminum anode assembly medium-frequency furnace, so as to solve the hidden danger of the furnace body tipping backward due to the lack of safety protection devices and the fact that the tilting action of the electrolytic aluminum anode assembly medium-frequency furnace is controlled by only a reducer. By installing a stop device on the fixed foundation on both sides of the lower part of the furnace body, a physical barrier is formed when the furnace body tilts backward abnormally, preventing the high-temperature molten iron from spilling onto the bottom of the furnace and scalding the water pipes, avoiding explosion accidents, and ensuring the safety of personnel and stable operation of equipment.

[0004] A device for preventing the tilting of an electrolytic aluminum anode assembly medium-frequency furnace includes:

[0005] The medium-frequency furnace body is provided with a first rotating shaft support component and a second rotating shaft support component. The first rotating shaft support component and the second rotating shaft support component are symmetrically distributed on both sides of the medium-frequency furnace body and are located on the same straight line.

[0006] The first furnace body fixing wall and the second furnace body fixing wall are respectively provided on both sides of the medium frequency furnace body, wherein the first rotating shaft support component is provided on the top of the first furnace body fixing wall;

[0007] A drive reducer is installed on the top of the second furnace body fixed wall and connected to the second rotating support component;

[0008] The first stop device and the second stop device are respectively installed on the first furnace body fixed wall and the second furnace body fixed wall by stop device fixing bolts.

[0009] Furthermore, the first stop device and the second stop device are respectively connected to the first furnace body fixing wall and the second furnace body fixing wall by at least two stop device fixing bolts, and the bolt spacing of the same stop device is no more than 200mm.

[0010] Furthermore, the first stop device and the second stop device are axially symmetrical and identical in shape.

[0011] Furthermore, the surfaces of the first furnace body fixing wall and the second furnace body fixing wall are parallel to each other and are distributed symmetrically about the axis of the medium frequency furnace body.

[0012] Furthermore, the first stop device and the second stop device are perpendicular to the first furnace body fixed wall and the second furnace body fixed wall, respectively, and the first stop device and the second stop device are located on the same plane.

[0013] Furthermore, the stop device is a rectangular plate structure, with its length direction perpendicular to the axis of the medium-frequency furnace body and its width direction consistent with the backward tilting direction of the furnace body.

[0014] Furthermore, the upper edges of the first stop device and the second stop device maintain a safe distance of more than 0.5 meters from the drive components at the bottom of the medium-frequency furnace body.

[0015] Furthermore, the first stop device and the second stop device are made of steel plates with a thickness of not less than 12mm.

[0016] Furthermore, the height of the first furnace body fixed wall is higher than that of the second furnace body fixed wall.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. Dual-limit safety protection: By symmetrically setting the first and second stop devices on the first and second furnace body fixed walls on both sides of the medium-frequency furnace body, a rigid mechanical limit structure is formed. This, together with the transmission control of the drive reducer, forms a "dual protection" to effectively prevent the furnace body from overturning excessively due to reducer failure or loss of control, avoid safety accidents caused by high-temperature molten iron spillage, and significantly improve the safety of equipment operation.

[0019] 2. Symmetrical Layout for Balanced Stress: The first and second furnace body fixed walls are symmetrically distributed along the furnace body axis, and the stop devices are symmetrical in shape and at the same height, ensuring that the stop devices on both sides are subjected to uniform stress when the furnace body tilts backward, avoiding structural damage caused by stress concentration on one side; at the same time, the stop devices are perpendicular to the fixed walls and located on the same plane, which, together with the linear distribution of the furnace body rotating support components, forms a stable limiting plane, improving the mechanical stability of the overall structure.

[0020] 3. The precise installation of the anti-interference stop device adopts a rectangular plate structure. Its length direction is perpendicular to the furnace body axis, and its width direction matches the backward tilting direction. It also maintains a safe distance of more than 0.5 meters from the furnace body drive components. This ensures the accuracy of the limit function and avoids mechanical interference during normal tilting operations. Combined with a fastening installation method with a fixing bolt spacing of ≤200mm and a steel plate material with a thickness of not less than 12mm, the stop device ensures long-term reliable operation in high temperature and vibration environments, reducing equipment maintenance costs.

Detailed Implementation

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] The following is in conjunction with the appendix Figure 1 To be continued Figure 3 The present invention will be described in detail with reference to specific embodiments:

[0028] like Figure 1-3 As shown, a device for preventing the tilting of an electrolytic aluminum anode assembly medium-frequency furnace includes:

[0029] The furnace body 1 of the medium frequency furnace has a first rotating shaft support component 11 and a second rotating shaft support component 12 on both sides of the furnace body 1. The two are symmetrically distributed on both sides of the furnace body axis and are located on the same straight line, providing a rotation fulcrum for the furnace body 1.

[0030] The first furnace body fixing wall 2 and the second furnace body fixing wall 3 are respectively located on the left and right sides of the furnace body 1. The first rotating shaft support component 11 is fixed to the top of the first furnace body fixing wall 2, and the furnace body 1 can rotate without obstruction through the bearing assembly.

[0031] The drive reducer 4 is installed on the top of the second furnace body fixed wall 3, and its output shaft is rigidly connected to the second rotating shaft support component 12 to provide the furnace body tilting driving force.

[0032] The first stop device 5 and the second stop device 6 are respectively anchored to the first furnace body fixing wall 2 and the second furnace body fixing wall 3 by the stop device fixing bolts 7. Their limiting surfaces cooperate with the lower outer surface of the furnace body 1 to prevent the furnace body from tilting backward to a dangerous angle.

[0033] The first stop device 5 and the second stop device 6 are respectively connected to the corresponding fixed wall by ≥2 stop device fixing bolts 7, with the bolt spacing ≤200mm, forming a multi-point anchoring structure to disperse the backward tilting impact force of the furnace body.

[0034] The first stop device 5 and the second stop device 6 are axially symmetrical rectangular plates. The length direction is perpendicular to the axis of the furnace body 1 (along the radial direction of the furnace body), and the width direction (along the axial direction of the furnace body) covers 1.2 times the width of the furnace body support surface, ensuring that the limiting contact area is sufficient and avoiding deformation due to single-point force.

[0035] The first furnace body fixing wall 2 and the second furnace body fixing wall 3 are parallel to each other and mirror-symmetrical about the axis of the furnace body 1. The distance between them is ≥ 1 / 2 of the furnace body diameter, forming a stable triangular support system to counteract the tilting torque of the furnace body.

[0036] The first stop device 5 and the second stop device 6 are respectively vertically welded to the side of the corresponding fixed wall, and the limiting surfaces of the two are coplanar. The angle between this plane and the rearward tilting direction of the furnace body 1 is 90°-120°, ensuring that the limiting force acts directly on the lower part of the furnace body's center of gravity.

[0037] The first furnace body fixed wall 2 is higher than the second furnace body fixed wall 3, which is adapted to the equal height arrangement of the first rotating shaft support component 11 and the second rotating shaft support component 12, so that the rotation center of the furnace body 1 remains horizontal.

[0038] The upper edges of the first stop device 5 and the second stop device 6 maintain a safe distance of ≥0.5m from the lower drive components (such as the reducer coupling) of the furnace body 1, which does not hinder normal tilting operation and can trigger the limit switch immediately in case of loss of control.

[0039] The first stop device 5 and the second stop device 6 are made of Q345B steel plate with a diameter of δ≥12mm and hot-dip galvanized surface treatment. They can withstand high temperatures above 300℃ and corrosion from splashing aluminum liquid, meeting the harsh working conditions of the electrolysis workshop.

[0040] The height of the first furnace body fixed wall 2 is higher than that of the second furnace body fixed wall 3. Since the second furnace body fixed wall 3 needs to be equipped with a drive reducer 4, its height is slightly lower than that of the first furnace body fixed wall 2, so as to ensure that the first rotating shaft support component 11 and the second rotating shaft support component 12 are located on the same straight line and at the same horizontal height.

[0041] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
