Description

Technical Field

[0001] This utility model relates to the field of end caps, and more specifically, to an integrated hot and cold pressing device for end caps. Background Technology

[0002] End caps are key components used to seal the ends of containers and isolate the internal and external media. They are widely used in pressure vessels or atmospheric storage tanks in fields such as petrochemicals, food and pharmaceuticals, energy and environmental protection. Traditional end caps usually use mechanical locking methods, which are convenient to disassemble and assemble, but their functions are relatively simple and cannot meet the process requirements of modern industry that require heating, heat preservation or cooling of materials inside the container.

[0003] However, end caps with heating or cooling functions are time-consuming and labor-intensive to assemble and disassemble, and can only be disassembled after the end caps have cooled down. Therefore, the integration of quick assembly and disassembly functions with temperature control functions into one end cap has become an urgent problem to be solved. Utility Model Content

[0004] The purpose of this invention is to provide an integrated hot and cold pressing device for end caps to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A head hot and cold pressing integrated device includes a head body, which is composed of several rigid body segments and telescopic segments. A threaded channel is provided at the center of the top of each rigid body segment, and a central screw is provided in the threaded channel. A rotating disk is provided at the top of the central screw, and a pressure plate is fixedly connected to the bottom of the central screw. A top rod is rotatably connected around the pressure plate, and the other end of the top rod is rotatably connected to an extension plate at the bottom of the rigid body segment. The device also includes a heating structure and a lifting structure.

[0006] Furthermore, the heating structure includes a heat-conducting rod, a resistance wire, and a mounting plate. The mounting plate is fixed to the bottom of the pressure plate by a central fixing frame. The heat-conducting rod is disposed at the bottom of the mounting plate, and the resistance wire is wound around the outer periphery of the heat-conducting rod.

[0007] Furthermore, the lifting structure includes a detachable lifting rod, and the rigid body flap is provided with a connection hole for connecting to the lifting rod.

[0008] Furthermore, a heat insulation block is provided on the heat transfer path between the rotating disk and the pressure plate, and the heat insulation block is made of high-temperature resistant material.

[0009] Furthermore, the rigid body flaps are arranged in several groups, and the number of top rods is equal to the number of rigid body flaps.

[0010] Compared with the prior art, the present invention has the following beneficial effects: By combining the quick-installation structure of the end cap with the resistance wire heating structure, the contradiction between the single function of the traditional quick-disassembly end cap and the inconvenience of disassembly and assembly of the traditional temperature-controlled end cap is resolved. This device can simultaneously meet the two functions of quick disassembly and assembly and internal heating, and is suitable for equipment such as intermediate storage tanks that require frequent material feeding and discharging and have requirements for material insulation or heating.

[0014] The utility model will now be further described in conjunction with the accompanying drawings and specific embodiments: Example 1: Please see Figure 1 and Figure 2A head hot and cold pressing integrated device includes a head body 1, which is composed of several rigid body petals 2 and telescopic petals 3. The number of rigid body petals 2 is arranged in several groups. The number of top rods 8 is equal to the number of rigid body petals 2. The rigid body petals 2 and telescopic petals 3 are symmetrically arranged. A threaded channel 4 is provided at the top center of the rigid body petal 2. A central screw 5 is provided in the threaded channel 4. A rotating disk 6 is provided at the top of the central screw 5. A pressure plate 7 is fixedly connected to the bottom of the central screw 5. Top rods 8 are rotatably connected around the pressure plate 7. The other end of the top rod 8 is rotatably connected to the extension plate 9 at the bottom of the rigid body petal 2. The device also includes a heating structure 100 and a lifting structure 200.

[0015] like Figure 1 As shown, during operation, the end cap is first placed above the tank body, the rotating disk 6 is rotated, the central screw 5 presses down the pressure plate 7 along the threaded channel 4, and at the same time the top rods 8 around the pressure plate 7 expand outward, pressing the extension plate 9 of the rigid body 2 against the inner wall of the tank body to form a closed space. Then the working element in the heating structure 100 is heated. After the heating operation is completed, the rotating disk 6 is rotated in the opposite direction to lift the central screw 5 and the pressure plate 7, and the top rods 8 pull the extension plate 9 to separate it from the tank body.

[0016] like Figure 1 and Figure 4 As shown, the heating structure 100 includes a heat-conducting rod 101, a resistance wire 102, and a mounting plate 103. The mounting plate 103 is fixed to the bottom of the pressure plate 7 by a central fixing bracket 13. The heat-conducting rod 101 is disposed at the bottom of the mounting plate 103. The resistance wire 102 is wound around the outer periphery of the heat-conducting rod 101. When the tank needs to be heated, heat is generated by the resistance wire 102, and the generated heat is conducted through the heat-conducting rod 101 to achieve heating.

[0017] like Figure 3 and Figure 5 As shown, the lifting structure 200 includes a detachable lifting rod 201. The rigid body petal 2 is provided with a connection hole 14 for connecting with the lifting rod 201. Before the operation begins, the detachable lifting rod 201 is connected to the connection hole 14 on the rigid body petal 2. Then, the entire end cap is lifted by a crane and placed on the tank. After the end cap is lowered, the lifting rod 201 is removed.

[0018] like Figure 1 As shown, a heat insulation block 15 is provided on the heat transfer path between the rotating disk 6 and the pressure plate 7. The heat insulation block 15 is made of high-temperature resistant material. When heating, it is necessary to open the end cap to add material. However, the temperature of the entire tank, including the end cap, will be very high, and it will take a long time to cool down. Setting a high-temperature resistant heat insulation block 15 between the rotating disk 6 and the central screw 5 can reduce the waiting time and improve the efficiency of the work.
