Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, specifically to a heat exchanger for chemical production. Background Technology

[0002] In the chemical production field, heat exchangers are key equipment for heat transfer and maintaining stable production process temperatures, and their performance directly affects production efficiency and energy consumption. Traditional chemical heat exchangers often use screw and nut connections for component assembly. During installation, tools such as wrenches and screwdrivers are needed to tighten the nuts, which is not only cumbersome but also extremely inefficient in large-scale production scenarios where heat exchangers are frequently replaced or reassembled, resulting in significant manpower and time costs. Furthermore, during operation, traditional heat exchangers are susceptible to loosening between components due to equipment vibration and media flow impacts, especially given the insufficient stability of the connection structure. This leads to a decrease in the overall structural reliability of the heat exchanger, posing a risk of component detachment or damage, affecting production continuity and safety. In addition, the installation structure of traditional heat exchangers is insufficient to effectively withstand the vibrations of chemical production sites. Vibrations can cause internal component displacement and loosening of connections, thus affecting heat exchange efficiency, shortening equipment lifespan, and increasing maintenance costs. Moreover, traditional heat exchangers have poor sealing at component mating points, allowing media or impurities from chemical production to easily enter the components, interfering with normal operation and reducing equipment stability. Therefore, a new type of heat exchanger for chemical production is proposed. Utility Model Content

[0003] This utility model proposes a heat exchanger for chemical production. In terms of installation, it adopts an installation structure consisting of a limiting sleeve, a limiting block, and a moving rod. The operator pushes the limiting sleeve to slide on the connecting rod by moving the moving rod. When the limiting sleeve is in contact with the inner wall of the heat exchanger connecting plate, the limiting block disengages from the placement groove and is fixed in contact with the connecting rod. Installation can be completed without additional tools, which greatly reduces installation time compared with the traditional screw and nut connection.

[0004] According to one aspect, at least one embodiment of the present invention provides a heat exchanger for chemical production, comprising: a heat exchanger connecting plate, wherein heat exchange plates are disposed inside the heat exchanger connecting plate, and a connecting rod is inserted inside the heat exchanger connecting plate, wherein the heat exchange plates are installed through the connecting rod passing through the heat exchanger connecting plate;

[0005] A connecting rod is provided with a limiting sleeve on its outside. A placement groove is provided inside the limiting sleeve. A limiting block is placed inside the placement groove. A movable rod is fixedly connected to the limiting block. The movable rod passes through the limiting sleeve and is disposed outside the limiting sleeve.

[0006] For example, at least one embodiment of the present invention provides a heat exchanger for chemical production, which further includes: a pull handle fixedly connected to the outer end of the moving rod, and the outer wall of the pull handle is provided with anti-slip texture.

[0007] For example, at least one embodiment of the present invention provides a heat exchanger for chemical production, which further includes: a spring wound around the outside of the moving rod, one end of the spring being fixedly connected to the pulling handle, and the other end of the spring being fixedly connected to the outer wall of the limiting sleeve.

[0008] For example, at least one embodiment of the present invention provides a heat exchanger for chemical production, which further includes: a limiting groove is formed on the surface of the limiting sleeve, a conical tooth block is fixedly connected inside the limiting groove, and an array of conical teeth is fixedly connected to the bottom end of the limiting block, wherein the conical tooth block and the tooth block array correspond to each other.

[0009] For example, at least one embodiment of the present invention provides a heat exchanger for chemical production, which further includes: a stabilizing groove is provided at the bottom end of the limiting sleeve, a stabilizing rod is fixedly connected to the bottom end of the connecting rod, and the stabilizing groove and the stabilizing rod are slidably connected.

[0010] For example, at least one embodiment of the present invention provides a heat exchanger for chemical production, which further includes: the outer wall of the limiting block and the inner wall of the placement groove are fitted together, and the moving rod and the hole groove through which the moving rod passes through the limiting sleeve are fitted together.

[0011] For example, at least one embodiment of the present invention provides a heat exchanger for chemical production, which further includes: two sets of connecting rods arranged symmetrically on the heat exchanger connecting plate.

[0012] For example, at least one embodiment of the present invention provides a heat exchanger for chemical production, which further includes: a placement seat fixedly connected to the bottom end of the heat exchanger connecting plate, and a shock-absorbing base fixedly connected inside the placement seat.

[0013] The working principle and beneficial effects of this utility model are as follows: In terms of installation, an installation structure consisting of a limiting sleeve, a limiting block, and a moving rod is adopted. The operator pushes the limiting sleeve to slide on the connecting rod through the moving rod. When the limiting sleeve is in contact with the inner wall of the heat exchanger connecting plate, the limiting block disengages from the placement groove and is fixed in contact with the connecting rod. Installation can be completed without additional tools, which greatly reduces installation time compared with the traditional screw and nut connection. Taking the heat exchanger assembly scenario in daily chemical production as an example, the traditional method takes more than minutes to install a heat exchanger, while this structure only takes - minutes, which significantly improves the assembly and replacement efficiency of heat exchangers in large-scale production. In terms of stability, the conical toothed blocks on the surface of the limiting sleeve and the toothed block group at the bottom of the limiting block mesh with each other. Combined with the sliding connection between the stabilizing groove at the bottom of the limiting sleeve and the stabilizing rod at the bottom of the connecting rod, the radial movement of the limiting sleeve is restricted, so that it can only slide along the axial direction. This enhances the connection stability between the limiting block and the limiting sleeve, effectively resists equipment vibration and medium flow impact, prevents components from loosening and shifting, and ensures the stability of the overall structure of the heat exchanger during operation.

[0014] In terms of operational safety and convenience, the pull handle at the outer end of the moving rod is equipped with anti-slip textures to increase the friction between the operator's hand and the pull handle, ensuring stable operation even in oily environments and preventing operational errors caused by slippage. The spring on the outside of the moving rod provides an elastic reset function. When disassembling, pulling the pull handle overcomes the spring force, returning the limit block to its initial position, ensuring a smooth and repetitive installation and disassembly process and reducing operational difficulty. In addition, the tight fit design between the limit block and the placement groove, and between the moving rod and the limit sleeve groove, reduces component gaps, prevents the entry of media or impurities from affecting component operation, and improves structural sealing and stability. Two sets of symmetrically arranged connecting rods evenly distribute pressure and gravity, preventing deformation of the heat exchanger connecting plate. The vibration damping base inside the placement seat uses elastic materials and a special structure to convert and dissipate the equipment's vibration energy, reducing the impact of vibration on the heat exchanger, extending the equipment's service life, and reducing maintenance costs.

Therefore, they should not be construed as limitations on this utility model.

[0026] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0027] Refer to the instruction manual appendix Figure 1-4 A heat exchanger for chemical production includes a heat exchanger connecting plate 1, heat exchange plates 2 are provided inside the heat exchanger connecting plate 1, and a connecting rod 3 is inserted inside the heat exchanger connecting plate 1. The heat exchange plates 2 are installed through the connecting rod 3 that passes through the heat exchanger connecting plate 1.

[0028] A connecting rod 3 is fitted with a limiting sleeve 4 on its outside. A placement groove 5 is opened inside the limiting sleeve 4, and a limiting block 6 is placed inside the placement groove 5. A moving rod 7 is fixedly connected to the limiting block 6, and the moving rod 7 passes through the limiting sleeve 4 and is positioned outside the limiting sleeve 4. The basic component of the heat exchanger is the heat exchanger connecting plate 1, which serves as the basic support structure for the entire heat exchanger, providing an installation base for other components. Heat exchange plates 2 are arranged in an orderly manner inside the heat exchanger connecting plate 1. The heat exchange plates 2 are the core components for heat exchange; through their large contact surface, they can effectively increase the heat exchange area, thereby improving heat transfer efficiency. A connecting rod 3 is inserted inside the heat exchanger connecting plate 1, and the heat exchange plates 2 are installed and fixed by the connecting rod 3 passing through the heat exchanger connecting plate 1. This installation method ensures that the heat exchange plates 2 form a stable arrangement within the heat exchanger connecting plate 1, guaranteeing the orderly progress of the heat exchange process.

[0029] As an important connecting component, the connecting rod 3 is fitted with a limiting sleeve 4. The limiting sleeve 4 plays a crucial role in limiting and fixing the entire structure. It has a placement groove 5 inside, and a limiting block 6 is placed inside the placement groove 5. The limiting block 6 is fixedly connected to a moving rod 7, which passes through the limiting sleeve 4 and is set outside it. During the installation process, the operator pushes the limiting sleeve 4 with the moving rod 7, so that the limiting sleeve 4 slides on the connecting rod 3 until it is in contact with the inner wall of the heat exchanger connecting plate 1. At this time, the limiting block 6 will detach from the placement groove 5 and be fixed in contact with the connecting rod 3. Compared with the traditional screw and nut connection method, this installation method does not require the use of additional tools such as wrenches and screwdrivers. The installation of the heat exchanger connecting plate 1, heat exchange plate 2 and connecting rod 3 can be completed by simple manual operation, which reduces the installation time cost. It is especially suitable for the rapid assembly and replacement of heat exchangers in large-scale chemical production.

[0030] To further facilitate the operation of the moving rod 7, a pull handle 8 is fixedly connected to the outer end of the moving rod 7. The outer wall of the pull handle 8 is provided with anti-slip texture. This anti-slip texture design can increase the friction between the operator's hand and the pull handle 8. In actual operation, whether in a dry environment or a chemical production environment with a small amount of oil, the operator can hold the pull handle 8 stably and pull the moving rod 7 to realize the movement of the limiting sleeve 4 and the operation of the limiting block 6, avoiding operational errors caused by hand slippage and improving the stability and safety of operation.

[0031] Meanwhile, a spring 9 is wound around the outside of the moving rod 7. One end of the spring 9 is fixedly connected to the pulling handle 8, and the other end is fixedly connected to the outer wall of the limiting sleeve 4. The spring 9 provides an elastic reset function for the entire structure. When the limiting sleeve 4 slides into place on the connecting rod 3 and the limiting block 6 is fixed to the connecting rod 3, the spring 9 is in a compressed state. When the heat exchanger components need to be disassembled later, the operator pulls the pulling handle 8 to overcome the elastic force of the spring 9, so that the limiting block 6 is disengaged from the connecting rod 3 and returns to the placement groove 5. Then the limiting sleeve 4 can be removed from the connecting rod 3. The elastic reset function of the spring 9 allows the limiting block 6 to accurately return to the initial position, preparing for the next installation and ensuring the continuity and repeatability of the installation and disassembly process.

[0032] The limiting sleeve 4 has a limiting groove 10 on its surface. A conical toothed block 12 is fixedly connected inside the limiting groove 10, and an array of conical teeth is fixedly connected to the bottom end of the limiting block 6. The conical toothed block 12 and the toothed block group 11 correspond to each other. When the limiting block 6 is detached from the placement groove 5 and is fixedly attached to the connecting rod 3, the toothed block group 11 will mesh with the conical toothed block 12. This meshing structure further enhances the connection stability between the limiting block 6 and the limiting sleeve 4, preventing the limiting block 6 from loosening or shifting due to factors such as equipment vibration and medium flow impact during chemical production, thereby ensuring the stability of the entire heat exchanger structure during operation.

[0033] In addition, a stabilizing groove 13 is provided at the bottom of the limiting sleeve 4, and a stabilizing rod 14 is fixedly connected to the bottom of the connecting rod 3. The stabilizing groove 13 and the stabilizing rod 14 are slidably connected. This sliding connection provides guidance and stability for the sliding of the limiting sleeve 4 on the connecting rod 3. During the sliding process of the limiting sleeve 4, the stabilizing rod 14 always slides in the stabilizing groove 13, which restricts the radial movement of the limiting sleeve 4 and makes it slide only along the axial direction of the connecting rod 3. This ensures the accuracy and stability of the movement of the limiting sleeve 4, avoids deviation or jamming, and further improves the reliability during installation and use.

[0034] In terms of structural fit, the outer wall of the limiting block 6 fits into the inner wall of the placement groove 5, and the moving rod 7 fits into the hole groove through the limiting sleeve 4. This tight fit design can effectively reduce the gap between components and prevent the medium or impurities from entering the components during the chemical production process, affecting the normal operation of the limiting block 6 and the moving rod 7. At the same time, the tight fit structure also helps to improve the sealing and stability of the entire structure.

[0035] To ensure the balance and stability of the heat exchanger connecting plate 1 during installation, two sets of connecting rods 3 are symmetrically arranged on the heat exchanger connecting plate 1. The two sets of symmetrically arranged connecting rods 3 can evenly distribute the pressure and gravity borne by the heat exchanger connecting plate 1 and the heat exchange plate 2, avoiding deformation or damage to the heat exchanger connecting plate 1 due to uneven force, and extending the service life of the heat exchanger.

[0036] A placement seat 15 is fixedly connected to the bottom of the heat exchanger connecting plate 1, and a vibration damping base 16 is fixedly connected inside the placement seat 15. In chemical production sites, equipment will generate vibrations of varying degrees during operation. The vibration damping base 16 can effectively absorb and buffer these vibrations. Through the elastic material and special structural design inside the vibration damping base 16, the vibration energy generated by the equipment operation is converted into heat energy or other forms of energy for consumption, reducing the impact of vibration on the heat exchanger connecting plate 1.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
