Description

Technical Field

[0001] This utility model relates to the field of vulcanization processing technology, and in particular to an insulating heating and constant temperature structure for vulcanization equipment. Background Technology

[0002] Vulcanization is a complex chemical reaction process that requires specific temperatures. Different types of materials and different vulcanization systems have different temperature requirements. Heating and temperature control devices can precisely control the temperature inside the vulcanization equipment within the required range, ensuring that the material undergoes a vulcanization reaction at a suitable temperature, causing the material molecular chains to cross-link, thereby obtaining the desired physical and mechanical properties.

[0003] Currently, vulcanizing equipment commonly employs three technical approaches: electric heating, steam heating, and thermal oil heating. Electric heating directly converts electrical energy into heat energy through electric heating tubes. Its advantages include rapid temperature response, high temperature control accuracy, and ease of integration with automated control systems to achieve closed-loop temperature regulation. Steam heating relies on high-temperature, high-pressure steam generated by steam boilers, which is transported to the vulcanizing equipment through a pipeline network. Its advantages include high heat density and uniform heating, but it requires the construction of a steam pipeline network, resulting in a more complex system. Thermal oil heating systems use thermal oil as a medium, leveraging its high-temperature stability and fluidity to achieve precise temperature control between the heating and cooling systems via a circulating pump. This is particularly suitable for large-scale continuous vulcanizing production lines.

[0004] Although electric heating methods excel in temperature controllability and automation integration, they still face two major challenges in practical applications: First, when the heating element is in direct contact with the material or the inner wall of the equipment, it is easy to form "hot spots" due to local heat accumulation, resulting in uneven vulcanization, affecting the consistency of product performance, and it is also easily damaged when in contact with corrosive gases in the vulcanization environment; Second, the heating element is difficult to disassemble after installation, resulting in reduced maintenance efficiency. Utility Model Content

[0005] The purpose of this utility model is to solve the problems of uneven heat transfer when electric heating tubes heat vulcanizing equipment, and the difficulty of disassembly and assembly, which is not conducive to maintenance in the prior art. Therefore, an insulating heating and constant temperature structure for vulcanizing equipment is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An insulating heating and constant temperature structure for a vulcanizing equipment includes a bottom shell and further includes: a top cover rotatably connected to the bottom shell, with an electric heating tube provided between the bottom shell and the top cover; a heat-conducting shell fixedly installed on the top cover, wherein the top cover has a heating part for conducting heat to the heat-conducting shell; and a connector installed on the bottom shell, wherein the connector is used to lock and position the top cover.

[0008] In order to conduct heat to the heat-conducting shell, preferably, the heating part includes: a first heat-conducting plate fixedly connected to the upper cover, a heat-conducting rod fixedly connected to the first heat-conducting plate, wherein a second heat-conducting plate is fixedly connected to the side of the heat-conducting rod away from the first heat-conducting plate, a heat-conducting column is fixedly connected to the side of the second heat-conducting plate away from the heat-conducting rod, and the side of the heat-conducting column away from the second heat-conducting plate is fixedly connected to the heat-conducting shell.

[0009] To further improve heat conduction efficiency, the heat-conducting rod is X-shaped and made of copper.

[0010] To disperse heat and prevent localized overheating of the heat-conducting shell, the heat-conducting column is further tapered, made of copper, with its small end fixedly connected to the second heat-conducting plate and its large end fixedly connected to the heat-conducting shell.

[0011] To facilitate quick disassembly of the heating element, the connector preferably includes: a positioning block, fixedly connected to the bottom shell and symmetrically arranged along the center line of the bottom shell, wherein a bidirectional lead screw is rotatably connected to the positioning block, and a threaded sleeve is threadedly connected to the bidirectional lead screw; an insertion rod, slidably connected inside the bottom shell, wherein one end of the insertion rod is fixedly connected to a slider that is fixedly connected to the threaded sleeve; and a limiting block, fixedly connected to the upper cover and symmetrically arranged along the center line of the upper cover, wherein the limiting block has an insertion hole for insertion into the insertion rod.

[0012] To facilitate the rotation of the bidirectional lead screw by the operator, a protective sleeve is further provided on the bidirectional lead screw, and the surface of the protective sleeve is provided with anti-slip strips.

[0013] To provide insulation and protection for the heating element, preferably, both the bottom shell and the top cover are made of ceramic fiber, and both the bottom shell and the top cover are provided with serpentine grooves.

[0014] For the purpose of limiting the installation of the heating element, preferably, the heating element is serpentine and is snapped into the serpentine groove.

[0015] Compared with the prior art, this utility model provides an insulated heating and constant temperature structure for vulcanization equipment, which has the following beneficial effects:

[0016] 1. The insulating heating and constant temperature structure of this vulcanizing equipment, through the X-shaped heat-conducting rod, forms a double heat conduction path, which can improve the heat transfer efficiency. When the bottom is heated, the heat is transferred upwards simultaneously through the two branches. The branch structure increases the contact area between the heat-conducting rod and the medium, promoting heat exchange.

[0017] 2. The insulating heating and constant temperature structure of the vulcanizing equipment uses a conical heat-conducting column, with the large end of the heat-conducting column connected to the heat-conducting shell, so that the heat flow can be dispersed on the heat-conducting shell, reducing the risk of local overheating and thus ensuring the uniform distribution of heat on the heat-conducting shell.

[0018] 3. The insulating heating and constant temperature structure of this vulcanizing equipment, through the bottom shell and top cover made of ceramic fiber material, can provide heat preservation and protection for the electric heating tube, extending its service life.

[0019] The parts of this device not covered herein are the same as or can be implemented using existing technologies. By setting up a heating section, this utility model can improve heat transfer efficiency and disperse heat on the heat-conducting shell, reducing the risk of local overheating. At the same time, the bottom shell and top cover made of ceramic fiber material can provide heat insulation and protection for the electric heating tube, extending its service life. Furthermore, the bottom shell and top cover can be quickly opened using connectors, thereby improving the maintenance efficiency of the electric heating tube. Attached Figure Description

[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 of the present utility model.

[0031] Example:

[0032] Reference Figures 1-8 An insulating heating and constant temperature structure for a vulcanizing equipment includes a bottom shell 1 and an upper cover 2 rotatably connected to the bottom shell 1. An electric heating tube 5 is provided between the bottom shell 1 and the upper cover 2. The electric heating tube 5 is serpentine. Both the bottom shell 1 and the upper cover 2 are made of ceramic fiber, which has heat insulation and thermal insulation properties. It wraps around the electric heating tube 5, providing protection. Both the bottom shell 1 and the upper cover 2 have serpentine grooves, and the electric heating tube 5 is engaged within these grooves. A heat-conducting shell 3 is fixedly installed on the upper cover 2, wherein the upper cover 2 has a heating section 4 for conducting heat to the heat-conducting shell 3. A connector 6 is installed on the bottom shell 1, wherein the connector 6 is used to lock and position the upper cover 2.

[0033] Specifically, by setting up the heating section 4, the heat transfer efficiency can be improved, and the heat can be distributed on the heat-conducting shell 3, reducing the risk of local overheating. At the same time, the bottom shell 1 and the top cover 2 made of ceramic fiber material can provide heat insulation and protection for the electric heating tube 5, extending its service life. Furthermore, the bottom shell 1 and the top cover 2 can be quickly opened using the connector 6, thereby improving the maintenance efficiency of the electric heating tube 5.

[0034] The heating unit 4 includes: a first heat-conducting plate 41, which is fixedly connected to the upper cover 2. A heat-conducting rod 42 is fixedly connected to the first heat-conducting plate 41. The heat-conducting rod 42 is X-shaped and made of copper. When the heating element 5 stops heating, the heat from the heat-conducting rod 42 is quickly discharged through the forming groove. A second heat-conducting plate 43 is fixedly connected to the side of the heat-conducting rod 42 away from the first heat-conducting plate 41. A heat-conducting column 44 is fixedly connected to the side of the second heat-conducting plate 43 away from the heat-conducting rod 42. The heat-conducting column 44 is conical and made of copper. The small end of the heat-conducting column 44 is fixedly connected to the second heat-conducting plate 43, and the large end is fixedly connected to the heat-conducting shell 3.

[0035] Specifically, through the setting of the heating section 4, during the continuous heating process, the heat on the surface of the electric heating tube 5 is transferred upward to the first heat-conducting plate 41. The first heat-conducting plate 41 transfers the heat to the X-shaped heat-conducting rod 42. The X-shaped cross structure forms a dual heat conduction path, which can improve the heat transfer efficiency. When the bottom is heated, the heat is transferred upward simultaneously through the two branches. The branch structure increases the contact area between the heat-conducting rod 42 and the medium, promoting heat exchange. After the heat-conducting rod 42 transfers heat to the second heat-conducting plate 43, the second heat-conducting plate 43 transfers the heat to the heat-conducting shell 3 through the heat-conducting column 44. Since the large end of the conical heat-conducting column 44 is connected to the heat-conducting shell 3, the heat flow can be dispersed on the heat-conducting shell 3, reducing the risk of local overheating.

[0036] The connector 6 includes: a positioning block 61, which is fixedly connected to the bottom shell 1 and symmetrically arranged along the center line of the bottom shell 1, wherein a bidirectional lead screw 62 is rotatably connected to the positioning block 61, and a threaded sleeve 63 is threadedly connected to the bidirectional lead screw 62; an insertion rod 64, which is slidably connected inside the bottom shell 1, wherein one end of the insertion rod 64 is fixedly connected to a slider 65 that is fixedly connected to the threaded sleeve 63; and a limiting block 66, which is fixedly connected to the upper cover 2 and symmetrically arranged along the center line of the upper cover 2, wherein the limiting block 66 has an insertion hole for insertion and engagement with the insertion rod 64, and a protective sleeve 67 is fixedly sleeved on the bidirectional lead screw 62, and the surface of the protective sleeve 67 is provided with anti-slip strips.

[0037] Specifically, by setting the connector 6, rotating the sheath 67 causes the bidirectional screw 62 to drive the two insert rods 64 to move in opposite directions, which can quickly open the top cover 2, thus facilitating the staff to remove the heating element 5 from the serpentine groove for maintenance.

[0038] During use, the operator uses an external power source to heat the heating element 5. As the heating element 5 continues to heat, the heat on its surface is transferred upwards to the first heat-conducting plate 41. The first heat-conducting plate 41 then transfers the heat to the X-shaped heat-conducting rod 42. This X-shaped cross structure forms a dual heat conduction path, improving heat transfer efficiency. When the bottom is heated, heat is simultaneously transferred upwards through two branches. This branch structure increases the contact area between the heat-conducting rod 42 and the medium, promoting heat exchange. After the heat-conducting rod 42 transfers heat to the second heat-conducting plate 43, the second heat-conducting plate 43 transfers the heat to the heat-conducting shell 3 through the heat-conducting column 44. Because the large end of the conical heat-conducting column 44 is connected to the heat-conducting shell 3, the heat flow can be dispersed on the heat-conducting shell 3, reducing the risk of localized overheating and ensuring uniform heat distribution on the heat-conducting shell 3. Furthermore, the ceramic fiber bottom shell 1 and top cover 2 provide external protection for the heating element 5, improving the insulation performance of the heating and temperature-regulating structure and preventing damage from contact with corrosive gases in a sulfurized environment.

[0039] When the staff needs to disassemble and maintain the heating element 5, they rotate the sheath 67. As the sheath 67 rotates, it drives the bidirectional lead screw 62 to rotate. As the bidirectional lead screw 62 rotates, it drives the two threaded sleeves 63 to move in opposite directions. As the two threaded sleeves 63 move in opposite directions, they drive the two sliders 65 to move in opposite directions. As the two sliders 65 move in opposite directions, they drive the two insertion rods 64 to move in opposite directions. When the insertion rods 64 disengage from the slots of the limiting block 66, the top cover 2 can be rotated to open it. After opening, the staff can remove the heating element 5 from the serpentine groove of the bottom shell 1, thus completing the disassembly of the heating element 5 and improving the maintenance efficiency of the staff.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
