[0001] This utility model relates to the field of smelting furnace technology, specifically a smelting furnace with circulating heating function. Background Technology

[0002] A smelting furnace is an industrial furnace that heats metal or non-metal materials at high temperatures to melt them, thereby purifying, alloying, or preparing them for casting. It is one of the most core pieces of equipment in metallurgy, casting, chemical engineering, materials science, and other fields.

[0003] According to a public announcement (Announcement No.: CN217715895U), a large-scale hydraulic melting furnace with multi-chamber circulating heating is described above. The furnace body, heat insulation cotton, and inner lining are arranged in a hollow double-layer shell structure. The inner lining is fixed to the inner wall of the furnace body, which can achieve the effect of sound insulation and heat insulation, and prevent heat loss. In addition, the hollow layer is filled with heat insulation cotton, which improves the heat insulation effect. This makes the large-scale hydraulic melting furnace have excellent heat insulation effect and avoid burns to the workers.

[0004] However, the above-mentioned equipment generates a lot of heat during actual use, which can damage the furnace body after prolonged operation, requiring a lot of time for maintenance. In view of this, we propose a smelting furnace with circulating heating function. Utility Model Content

[0005] The purpose of this invention is to provide a smelting furnace with a circulating heating function to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a smelting furnace with circulating heating function, comprising a shell, a furnace body disposed at the bottom of the inner wall of the shell, a slot disposed on the outer surface of the furnace body, a cover plate disposed at the top of the shell, a limiting member fixedly connected to the bottom of the cover plate, and a protective assembly disposed on the inner wall of the shell, the protective assembly comprising: A spacer is fixedly connected to the bottom of the limiting member, and a heating element is fixedly connected to the inner wall of the housing; A buffer spring is fixedly connected to the bottom of the inner wall of the housing, and a pressure-bearing component is fixedly connected to the end of the buffer spring.

[0007] Preferably, the pressure-bearing component is L-shaped, and the upper surface of the horizontal part of the pressure-bearing component is in contact with the bottom of the furnace body. This allows the pressure-bearing component to effectively buffer the force of the furnace body descending during installation.

[0008] Preferably, the center of the heating element corresponds to the center of the inner wall of the housing, and the heating elements are arranged in a linear array and evenly distributed on the inner wall of the housing, which allows the heating elements to maintain the temperature inside the housing.

[0009] Preferably, the center of the partition corresponds to the center of the limiting member, and the bottom of the partition is in contact with the upper surface of the vertical part of the pressure-bearing member, so that the heat emitted by the furnace body can be blocked.

[0010] Preferably, an auxiliary component is provided on the upper surface of the furnace body. The auxiliary component includes a fixing member, which is fixedly connected to the upper surface of the furnace body. A handle is fixedly connected to the top of the fixing member, and a movable groove is provided on the side of the fixing member. A small spring is fixedly connected to the bottom of the inner wall of the movable groove, and a clip is fixedly connected to the end of the small spring.

[0011] Preferably, the size of the card is adapted to the size of the movable slot, the card is disposed inside the movable slot, and the upper surface of the card is provided with an arc-shaped surface.

[0012] Preferably, the center of the fixing member corresponds to the center of the handle, and there are two fixing members, which are symmetrically arranged with respect to the center of the furnace body.

[0013] Compared with the prior art, this utility model provides a smelting furnace with circulating heating function, which has the following beneficial effects:

[0014] 1. This smelting furnace with circulating heating function allows for easier maintenance by rotating the cover plate to allow the limiting component to rotate. This enables the cover plate to be removed from the bottom of the shell, facilitating furnace maintenance. After maintenance, the furnace body is installed on the bottom of the inner wall of the shell, where it is pressurized against the L-shaped pressure-bearing component. This allows for slow installation. The cover plate is then installed on the upper surface of the shell, ensuring contact between the bottom of the partition and the upper surface of the pressure-bearing component. This prevents heat dissipation from the furnace body, while the heat dissipated by the heating element keeps the outer surface of the partition at a constant temperature, effectively maintaining the furnace body's temperature.

[0015] 2. To ensure greater stability during hoisting of the smelting furnace with circulating heating function, the clamps are pressed to retract the small springs during hoisting. After connecting the hoisting hook to the handle, the clamps are released. This allows the spring force to push the clamps upward, thereby limiting the hoisting hook with the arc-shaped surface on the upper surface of the clamps. This makes the furnace body more stable during hoisting. Attached Figure Description

[0018] like Figures 1-4 As shown, this utility model provides a technical solution: a smelting furnace with circulating heating function, including a shell 1, a furnace body 2 provided at the bottom of the inner wall of the shell 1, a slot 3 provided on the outer surface of the furnace body 2, a cover plate 4 provided at the top of the shell 1, a limiting member 5 fixedly connected to the bottom of the cover plate 4, and a protective component 6 provided on the inner wall of the shell 1. The protective component 6 includes a partition 601, a heating element 602, a buffer spring 603, and a pressure-bearing element 604.

[0019] In this embodiment of the utility model, the spacer 601 is fixedly connected to the bottom of the limiting member 5, the center of the spacer 601 corresponds to the center of the limiting member 5, and the bottom of the spacer 601 is in contact with the upper surface of the vertical part of the pressure bearing member 604. This allows the heat emitted by the furnace body 2 to be shielded. The heating element 602 is fixedly connected to the inner wall of the shell 1, the center of the heating element 602 corresponds to the center of the inner wall of the shell 1, and the heating elements 602 are evenly distributed in a linear array on the inner wall of the shell 1. This allows the heating elements 602 to maintain the temperature inside the shell 1. The buffer spring 603 is fixedly connected to the bottom of the inner wall of the shell 1, and the end of the buffer spring 603 is fixedly connected to the pressure bearing member 604. The pressure bearing member 604 is L-shaped, and the upper surface of the horizontal part of the pressure bearing member 604 is in contact with the bottom of the furnace body 2. This allows the pressure bearing member 604 to effectively buffer the force of the furnace body 2 during installation.

[0020] Meanwhile, an auxiliary component 7 is provided on the upper surface of the furnace body 2. The auxiliary component 7 includes a fixing member 701, which is fixedly connected to the upper surface of the furnace body 2. The center of the fixing member 701 corresponds to the center of the handle 702. There are two fixing members 701, and the two fixing members 701 are symmetrically arranged with respect to the center of the furnace body 2. The handle 702 is fixedly connected to the top of the fixing member 701. A movable groove 703 is opened on the side of the fixing member 701. A small spring 704 is fixedly connected to the bottom of the inner wall of the movable groove 703. A clip 7 is fixedly connected to the end of the small spring 704. 05. The size of the clamp 705 is adapted to the size of the movable slot 703. The clamp 705 is set inside the movable slot 703. The upper surface of the clamp 705 is provided with an arc-shaped surface. When the furnace body 2 is hoisted, pressing the clamp 705 will cause the small spring 704 to retract. After connecting the hoisting hook to the handle 702, the clamp 705 is released. This allows the elastic force of the small spring 704 to push the clamp 705 upward, thereby allowing the arc-shaped surface on the upper surface of the clamp 705 to limit the hoisting hook. This makes the furnace body 2 more stable when hoisted.

[0021] In this utility model, during use, rotating the cover plate 4 causes the limiting member 5 to rotate, allowing the cover plate 4 to be removed from the bottom of the housing 1. This allows the furnace body 2 to be better inspected and repaired. After the furnace body 2 is inspected and repaired, it is installed on the bottom of the inner wall of the housing 1. The bottom of the furnace body 2 will be under pressure from the L-shaped pressure member 604, allowing the furnace body 2 to be installed slowly. At the same time, the cover plate 4 is installed on the upper surface of the housing 1, so that the bottom of the partition 601 contacts the upper surface of the pressure member 604. This allows the furnace body 2 to be blocked by the partition 601 after emitting heat, while the heat emitted by the heating element 602 keeps the outer surface of the partition 601 at a constant temperature, thus effectively maintaining the temperature of the furnace body 2.

[0022] Furthermore, when hoisting the furnace body 2, press the clamp 705 to retract the small spring 704, then connect the hoisting hook to the handle 702 and release the clamp 705. This allows the elastic force of the small spring 704 to push the clamp 705 upward, thereby allowing the arc-shaped surface on the upper surface of the clamp 705 to limit the hoisting hook, making the furnace body 2 more stable during hoisting.

[0023] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
