Abstract
Description
Technical Field
[0001] This utility model relates to a coil rack, and more particularly to a rotary coil device for pyrolysis, belonging to the field of biopharmaceutical equipment technology. Background Technology
[0002] Pyrolysis refers to the intentional disruption of the structure of cells, tissues, or macromolecules (e.g., proteins, nucleic acids, polymers) through physical, chemical, or biological methods in biological, chemical, or industrial processes, releasing their contents or breaking them down into smaller components. In the chemical, materials, and energy sectors, pyrolysis typically involves high temperatures, corrosive media, and certain system pressures. While conventional rigid pipes (e.g., stainless steel pipes) are durable, they have limitations in flexibility. Pyrolysis hoses, as a type of specialized flexible conduit, are suitable for conveying high-temperature, high-pressure, or corrosive pyrolysis reaction media, solving problems that rigid pipes cannot address. Therefore, in continuous, chemical / industrial-grade pyrolysis processes, dedicated pyrolysis hoses are an indispensable core component.
[0003] Currently, to ensure the safety and stability of pyrolysis systems in pyrolysis and even broader chemical processes, pyrolysis hoses are typically coiled for use in a coiled form to effectively absorb thermal stress, compensate for equipment displacement, optimize layout, and avoid sharp bends. To achieve the operation and arrangement of the corresponding coiled configuration and ensure its coiled stability, existing technologies generally rely on suitable coil supports.
[0004] Traditional coil racks typically consist of a spiral or cylindrical support structure with a predetermined diameter. In practice, operators must manually wind and secure the flexible pyrolysis hose along the trajectory of this rack to form a neat coil assembly. This method aims to confine the loose hose within a fixed geometric space to avoid the safety risks caused by its uncontrolled movement and to meet the requirements of limited equipment installation space.
[0005] However, existing coil rack structures still have inherent drawbacks. For example, during coiling, operators need to rotate around the rack to coil the pyrolysis hoses. Coiling a heavy and flexible metal hose onto the rack is a time-consuming and labor-intensive task, usually requiring multiple people and occupying a large amount of operating space. Furthermore, most systems use fixed structures designed for specific pipe diameters and lengths, lacking adjustability. When different specifications of pyrolysis hoses need to be replaced, the existing rack is often incompatible, leading to high maintenance costs and insufficient flexibility. Therefore, it is necessary to propose a rotary coiling device for pyrolysis to fundamentally overcome these shortcomings. Summary of the Invention
[0006] The purpose of this invention is to solve the above-mentioned problems and provide a rotary coil device for pyrolysis. By implementing this invention, not only can the coiling operation of the pyrolysis hose be completed safely and conveniently, but the reliability, maintainability and service life of the entire pyrolysis system can also be improved, which has the advantages of technological progress and economic benefits.
[0007] The technical solution of this utility model is: a rotary coil device for pyrolysis, comprising a support frame and a coil frame, wherein a slewing bearing disk is provided between the support frame and the coil frame, and the coil frame can rotate relative to the central axis of the slewing bearing disk, so that the coil frame can rotate smoothly relative to the support frame when subjected to external force, and can be positioned at any rotational position without wobbling after the external force is removed. The coil frame includes a circular seat, a rotating seat, lower support arms, a vertical rod, and an upper support arm. The circular seat and the rotating seat are concentrically arranged, and several lower support arms are evenly distributed circumferentially, with the first end of each lower support arm fixedly connected to the outer periphery of the rotating seat. The second end of the arm is fixedly connected to the inner periphery of the ring seat. The disk surface of the rotating seat and the ring surface of the ring seat are located in the same plane, such that the horizontal tangent of the disk is coplanar with the horizontal tangent of the ring. Several uprights are fixed vertically to the upper end face of the ring seat along the circumferential direction. The two ends of each upper support arm along its length direction are respectively connected to the side walls of two adjacent uprights, and all connection points are located near the top of the uprights. The upper support arms are connected end to end between the top positions of several uprights, forming a closed regular polygonal ring structure, thereby connecting several uprights into a whole. A coil support plate is fixed on the outer side of each upright.
[0008] Furthermore, in the aforementioned rotary coil device for pyrolysis, the coil support plate has a supporting and limiting function, and the coil support plate is provided with several coil slots for laterally inserting and removing the pyrolysis hose.
[0009] Furthermore, in the aforementioned rotary coil device for pyrolysis, the coil slots are arranged vertically or at intervals along a path adapted to the pyrolysis arrangement path on the coil support plate. The openings of the coil slots are provided with guide rounded corners or chamfers to facilitate the insertion and removal of the hose, and their contours are adapted to the outer diameter of the pyrolysis hose to be coiled. When the hose is inserted laterally from the opening and placed in the tank, the hose, guided by its own weight and the inclined wall of the tank, naturally slides into the tank and is stably secured, forming a spiral upward arrangement.
[0010] Furthermore, in the aforementioned rotary coil device for pyrolysis, a positioning arm is fixedly provided on one side of the support frame, and a positioning rod that can move up and down is movably connected to the end of the positioning arm.
[0011] Furthermore, in the aforementioned rotary coil device for pyrolysis, a locking part is provided between the positioning arm and the positioning rod. The locking part includes a hook and a groove, one of which is provided on the positioning arm and the other of which is provided on the positioning rod.
[0012] Furthermore, in the aforementioned rotary coil device for pyrolysis, the upper end of the positioning rod along its length is provided with a U-shaped positioning block that matches the outer diameter of the lower support arm.
[0013] Furthermore, in the aforementioned rotary coil device for pyrolysis, several omnidirectional casters are provided at the bottom of the support frame.
[0014] By employing the technical solution of this utility model, after pulling down the positioning rod and releasing the engagement between the positioning rod and the positioning arm, the positioning rod drives the U-shaped positioning block at its top to separate from its corresponding lower support arm, thereby releasing the coil rack from its stationary state. The required pyrolysis hose is then fixed into the coil slot at the bottom of the coil support plate on a certain upright. Then, depending on the coiling arrangement of the pyrolysis hose, the coil rack is rotated at an appropriate rate via the slewing bearing disc, causing the pyrolysis hose to spiral upwards and sequentially enter the corresponding other coil slots. Once the required coiling length of the pyrolysis hose is reached, the rotation of the coil rack can be stopped. This rotating coil rack provides physical support and constraint for the coiling of the pyrolysis hose, ensuring that the coil shape conforms to engineering specifications and preventing kinking, excessive bending, or accidental pulling of the pyrolysis hose due to arbitrary placement, which could affect subsequent pyrolysis use. After completing the coiling operation of the pyrolysis hose, the positioning rod is pushed up to engage the U-shaped positioning block with the corresponding lower support arm, thus re-restricting the rotation of the coil rack. Finally, the engagement between the positioning rod and the positioning arm is locked to prevent the positioning rod from sliding down.
[0015] Compared with the prior art, this utility model improves the fixed coil rack structure to a rotating one, eliminating the operator's movement path and eliminating the need to reserve a surrounding passage, thereby greatly reducing the planar layout size of the pyrolysis equipment and significantly improving the functional density per unit area. The device has a stable overall structure, is easy and labor-saving to operate, and the coiling process is faster after the rotation is activated, saving the time of human movement and greatly improving coiling efficiency and consistency. Moreover, the coil slot spacing can be changed to adapt to different specifications of pyrolysis hoses, improving the coiling adaptability and adjustability of the pyrolysis hoses.

Detailed Implementation
[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings to make it easier to understand and master. The components involved, such as the support frame 1, the support arm, the upright 6, and the swivel casters 14, are all commonly used by those skilled in the art, and there are no special requirements for them in this application.
[0023] like Figures 1-3 As shown, this utility model provides a rotary coil device for pyrolysis, including a support frame 1 and a coil rack. Several omnidirectional casters 14 are provided at the bottom of the support frame 1 for easy movement. A slewing bearing disk 2 is provided between the support frame 1 and the coil rack. The coil rack can rotate relative to the central axis of the slewing bearing disk 2, allowing it to rotate smoothly relative to the support frame 1 when subjected to external force, and to be positioned without wobbling at any rotational position after the external force is removed.
[0024] According to the technical solution of this utility model, the coil rack includes a circular seat 3, a rotating seat 4, a lower support arm 5, a vertical rod 6, and an upper support arm 9. The circular seat 3 and the rotating seat 4 are concentrically arranged. Several lower support arms 5 are evenly distributed circumferentially. The first end of each lower support arm 5 is fixedly connected to the outer periphery of the rotating seat 4, and the second end of each lower support arm 5 is fixedly connected to the inner periphery of the circular seat 3. The disk surface of the rotating seat 4 and the ring surface of the circular seat 3 are located in the same plane, such that the horizontal tangent of the disk 1 is coplanar with the horizontal tangent of the ring 2. Several uprights 6 are fixed vertically to the upper surface of the annular seat 3 along the circumferential direction. Each upper support arm 9 is connected at both ends along its length to the side walls of two adjacent uprights 6, and all connection points are located near the top of the uprights 6. The upper support arms 9 are connected end to end between the tops of the several uprights 6, forming a closed regular polygonal ring structure, thereby connecting the several uprights 6 into a whole. A coil support plate 7 is fixed on the outer side of each upright 6.
[0025] Preferably, in the above structure: the coil support plate 7 has the function of supporting and limiting, and the coil support plate 7 is provided with several coil slots 8 for laterally inserting and removing the pyrolysis hose.
[0026] Preferably, in the above structure: the coil slots 8 are arranged vertically or along a path adapted to the pyrolysis arrangement path on the coil support plate 7, and the opening of the coil slots 8 is provided with guide rounded corners or chamfers to facilitate the insertion and removal of the hose, and its outline is adapted to the outer diameter of the pyrolysis hose to be coiled. When the hose is inserted from the side of the opening and placed in the tank, the hose, under its own weight and guided by the inclined wall of the tank, naturally slides into the tank and is stably locked, forming a spiral upward arrangement, which facilitates the discharge of air bubbles inside the hose and ensures accurate pyrolysis reaction time.
[0027] Furthermore, such as Figure 4 and Figure 5 As shown in the above structure: a positioning arm 12 is fixedly provided on one side of the support frame 1, and a positioning rod 10 that can move up and down is movably connected to the end of the positioning arm 12. A U-shaped positioning block 11 that matches the outer diameter of the lower support arm 5 is provided at the upper end of the positioning rod 10 along its length direction. The U-shaped positioning block 11 holds the lower support arm 5, thereby restricting the rotation of the coil rack.
[0028] Specifically, in the structure of the rotary coil device for pyrolysis described above, a locking part 13 is provided between the positioning arm 12 and the positioning rod 10. The locking part 13 includes a hook and a groove, wherein the hook is provided on the positioning arm 12 and the groove is provided on the positioning rod 10.
[0029] The key technical aspect of this invention lies in the combination of its rotary coil structure, stable coil clamping structure, and positioning structure that restricts the rotation of the coil rack. Figure 3 The focus of the exhibition is on the components involved in the overall rotary coil rack. Figure 4 and Figure 5 The diagram shows the specific structure and working state of the positioning structure (including positioning arm 12, positioning rod 10, and U-shaped positioning block 11). For components such as support frame 1, support arm, upright 6, and swivel casters 14, those skilled in the art can perform conventional settings based on existing technology. This case does not have any special requirements regarding the selection of their models or their combination.
[0030] Thus, by adopting the technical solution of this utility model, after pulling down the positioning rod 10 and releasing the locking part 13 between the positioning rod 10 and the positioning arm 12, the positioning rod 10 drives the U-shaped positioning block 11 at its top to separate from its corresponding lower support arm 5, thereby releasing the limited static state of the coil rack; the required pyrolysis hose is fixed into the coil slot 8 at the bottom of the coil support plate 7 of a certain upright 6, and then the coil rack can be rotated at an appropriate rate through the slewing bearing plate 2 according to the coiling situation of the pyrolysis hose, so that the pyrolysis hose spirals up and is placed into the corresponding other coil slots 8 in sequence. After reaching the required coiling length of the pyrolysis hose, the rotation of the coil rack can be stopped. This rotating coil rack provides physical support and constraint for the coiling of the pyrolysis hose, thereby ensuring that the coil shape conforms to the engineering specifications and avoiding the kinking, excessive bending or accidental pulling of the pyrolysis hose due to random placement, which would affect the subsequent pyrolysis use. After completing the coiling operation of the pyrolysis hose, push up the positioning rod 10 so that the U-shaped positioning block 11 is locked into the corresponding lower support arm 5, then restrict the rotation of the coil rack again, and then lock the locking part 13 between the positioning rod 10 and the positioning arm 12 to restrict the positioning rod 10 from sliding down.
[0031] As can be seen from the above description, compared with the prior art, the overall structure is stable and the operation is convenient and labor-saving after adopting the technical solution of this utility model. Replacing the fixed coil structure with a rotatable coil structure eliminates the operator's movement path and eliminates the need to reserve a loop, thereby greatly reducing the planar layout size of the equipment and significantly improving the functional density per unit area. After enabling rotation, the coiling process is faster, saving the time of human movement and greatly improving the coiling efficiency and consistency. Moreover, the coil slot spacing can be changed to adapt to different specifications of pyrolysis hoses, improving the coiling adaptability and adjustability of the pyrolysis hoses.
[0032] The technical solution, working process and implementation effect of this utility model have been described in detail above. It should be noted that the described example is only a typical example of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
