Description

Technical Field

[0001] This utility model relates to the technology of reaction vessels in the chemical industry, and in particular to a reaction vessel with fixed lighting and a staggered viewing window. Background Technology

[0002] A reaction vessel is a container used for physical or chemical reactions, widely used in various industries such as chemical, pharmaceutical, and food. A reaction vessel consists of a vessel body, which usually has a viewing hole. As the name suggests, a viewing hole is a hole used to observe the internal conditions, also known as a peephole, so that people can check the internal condition of the vessel without opening it.

[0003] There are two main types of sight holes in the industry. Most are located at the top of the vessel, while a few are located on the outer perimeter. When inspecting, workers shine a handlamp into the sight hole, which is inconvenient as it occupies both hands. With the sight hole at the top, workers looking down can generally only see the upward-facing portion of the vessel's interior. Similarly, with the sight hole on the outer perimeter, workers can only see the interior at the height corresponding to the sight hole.

[0004] In reality, the reaction / mixing conditions of substances at different depths inside the vessel will vary slightly. In order to observe the internal conditions of the vessel more comprehensively, the applicant considered lengthening the viewing holes on the outer perimeter of the vessel, that is, setting up a long strip-shaped observation window. However, forming a long continuous opening on the side wall of the reactor will inevitably weaken the structural strength and pressure-bearing capacity of the vessel.

[0005] Therefore, how to meet the need for comprehensive observation of the reactor's interior while minimizing changes to the original structure of the reactor body, while also reducing the weakening of the reactor's structural strength by the observation window, and freeing up the workers' hands and providing them with convenience, has become a new research topic for the applicant. Utility Model Content

[0006] In view of this, the present invention addresses the deficiencies of the existing technology and its main objective is to provide a reactor with fixed lighting and staggered viewing windows. It cleverly adds lighting to the existing viewing holes to form a dedicated lighting device that is always placed and points towards the inside of the reactor. At the same time, the cylindrical body is modified and multiple staggered viewing windows are provided to maximize the structural strength and pressure-bearing capacity of the reactor sidewalls while ensuring the observation range.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A reaction vessel with fixed lighting and staggered viewing windows includes a metal tank, the metal tank comprising a cylindrical body; a viewing hole is provided at the top of the metal tank, the viewing hole is fitted with a transparent plate and secured by a bolt assembly; an illumination lamp is added to the outside of the transparent plate, the light-emitting side of the illumination lamp facing the transparent plate to illuminate the interior of the metal tank, the illumination lamp being detachably mounted to the bolt assembly via a connecting piece; at least two sets of through-hole viewing windows are provided on the peripheral wall of the cylindrical body, all viewing windows being narrow strips extending vertically, and staggered horizontally and vertically; a strip-shaped transparent cover plate is provided on the outer peripheral side of the cylindrical body corresponding to the viewing windows.

[0008] As a preferred embodiment, all viewing windows are located on one side of the peripheral wall of the cylindrical body, while the lighting lamp is located on the top of the metal can, corresponding to the other side of the peripheral wall of the cylindrical body, so that the light from the lighting lamp shines towards the viewing windows.

[0009] As a preferred embodiment, the outer periphery of the strip-shaped transparent cover is provided with a pressure ring, which presses against the outer peripheral surface of the strip-shaped transparent cover and is locked to the peripheral wall of the cylindrical body with screws.

[0010] As a preferred embodiment, a ring of solder is welded between the outer periphery of the pressure ring and the outer surface of the peripheral wall of the cylindrical body.

[0011] As a preferred embodiment, a first sealing ring is provided between the inner surface of the pressure ring and the outer surface of the peripheral wall of the cylindrical body, and the screw passes through the first sealing ring.

[0012] As a preferred embodiment, the inner surface of the pressure ring is recessed with an annular step near the inner ring side, the strip-shaped transparent cover is installed at the annular step, and a second sealing ring is provided between the outer peripheral surface of the strip-shaped transparent cover and the annular step, and the first sealing ring is sandwiched between the inner peripheral surface of the strip-shaped transparent cover and the outer peripheral wall surface of the cylindrical body.

[0013] As a preferred embodiment, the lighting lamp includes a lamp body and a lampshade connected to the lower end of the lamp body. The outer periphery of the lamp body is provided with a connecting lug. The outer end of the connecting lug is detachably connected to the upper end hole of the connecting piece. A mounting screw passes through the upper end hole of the connecting piece and is screwed into the connecting lug to fix the upper end of the connecting piece. The lower end hole of the connecting piece is fitted onto the screw of the bolt assembly and locked by the nut of the bolt assembly.

[0014] As a preferred embodiment, a mounting ring is nested around the periphery of the transparent plate, and the bolt assembly is locked between the mounting ring and the top of the metal can.

[0015] As a preferred embodiment, a flange is installed inside the viewing hole, and the mounting ring is secured to the flange 1201 by the bolt assembly.

[0016] As a preferred option, the lighting is an LED explosion-proof light.

[0017] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly utilizes the existing top viewing hole to cleverly install a lighting lamp to form a permanent, dedicated lighting device pointing into the reactor, freeing up the workers' hands, providing convenience for the workers, and avoiding damage to the original structure of the reactor body, reducing manufacturing costs, simplifying the installation process, and achieving minimal modification to the original structure of the reactor body. At the same time, the cylindrical body is modified, and multiple staggered viewing windows ensure a full range of observation while maximizing the structural strength and pressure-bearing capacity of the reactor sidewall.

Detailed Implementation

[0020] Please refer to Figures 1 to 9 As shown, it illustrates the specific structure of an embodiment of the present invention.

[0021] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] A reaction vessel with fixed lighting and a staggered viewing window includes a metal tank body, the metal tank body comprising a cylindrical shell 10; a lower hemispherical head 11 is integrally connected to the lower end of the cylindrical shell 10, and an upper hemispherical head 12 is integrally connected to the upper end of the cylindrical shell 10. The lower hemispherical head 11 is welded to the lower end of the cylindrical shell 10, forming an annular weld. Similarly, the upper hemispherical head 12 is welded to the upper end of the cylindrical shell 10, forming an annular weld. Typically, a viewing hole is provided at the top of the metal tank body, the viewing hole being fitted with a transparent plate 123 and secured by a bolt assembly 122. An illumination lamp 60 is added to the outside of the transparent plate 123. The illumination lamp 60 is an LED explosion-proof lamp, which is a special lighting fixture widely used in environments with explosion hazards to provide safe and reliable lighting for specific scenarios. The light-emitting side of the illumination lamp 60 faces the transparent plate 123 to illuminate the interior of the metal tank. The illumination lamp 60 is detachably mounted to the bolt assembly 122 via a connecting piece 602. Typically, LED explosion-proof sight glass lights have connecting lugs 601 and mounting screws 603 on both sides for mounting brackets or carrying racks. When adding the light, first disassemble the bracket or carrying rack, and prepare an L-shaped hardware component as the connecting piece 602. The L-shaped hardware component includes a Y-shaped connecting piece (or a fisheye connecting piece) and a bending piece. One end of the Y-shaped connecting piece is an open ring for connecting to the connecting bolts, and the other end is a straight line that connects to the bending piece, bending perpendicularly to it. A connecting hole is provided on the bending piece for connecting to the existing connecting bolts on both sides of the LED explosion-proof sight glass light. Thus, by placing the LED explosion-proof sight glass light at the sight glass, it can illuminate the interior of the reactor. LED explosion-proof lights typically use high-brightness, energy-saving LEDs as the light source, which have advantages such as low energy consumption, long lifespan, and maintenance-free operation, so there is no need to worry about lighting failure.

[0023] The cylindrical body 10 has at least two sets of through windows 101 on its peripheral wall, extending both inside and out. All windows 101 are narrow strips extending vertically, with staggered spacing and alignment. A window mounting assembly 50 is provided on the outer periphery of the cylindrical body 10 corresponding to the windows 101, and the assembly includes a strip-shaped transparent cover 51. Workers can more intuitively and quickly observe the interior of the reactor through these long, narrow windows. Considering the structural strength of the reactor, two or more long, narrow windows are designed, staggered vertically and horizontally, effectively providing multiple windows for viewing the entire reactor vertically. Compared to a single long, narrow window extending to the top and bottom of the reactor, this multiple, shorter long, narrow window design is more structurally sound, avoiding long breaks in the reactor's peripheral wall in the vertical direction due to the long, narrow windows.

[0024] All viewing windows 101 are located on one side of the peripheral wall of the cylindrical body 10, while the lighting lamp 60 is located on the other side of the peripheral wall of the cylindrical body 10 at the top of the metal can, such that the light from the lighting lamp 60 shines towards the viewing window.

[0025] A pressure ring 52 is provided around the outer periphery of the strip-shaped transparent cover plate 51. The pressure ring 52 presses against the outer peripheral surface of the strip-shaped transparent cover plate 51 and is locked to the peripheral wall of the cylindrical body 10 by screws 53. Typically, a number of internally threaded holes are pre-set around the outer periphery of the viewing window 101 on the peripheral wall of the cylindrical body 10. The inner ends of these internally threaded holes are blind ends. A number of through holes are arranged circumferentially on the pressure ring 52 to correspond one-to-one with the internally threaded holes. A ring of solder 55 is welded between the outer periphery of the pressure ring 52 and the outer peripheral wall of the cylindrical body 10. A first sealing ring 54 is provided between the inner surface of the pressure ring 52 and the outer peripheral wall of the cylindrical body 10, and the screw 53 passes through the first sealing ring 54. The inner surface of the pressure ring 52 is recessed with an annular step near the inner ring side. The strip-shaped transparent cover plate 51 is installed at the annular step, and a second sealing ring 56 is provided between the outer peripheral surface of the strip-shaped transparent cover plate 51 and the annular step. The first sealing ring 54 is sandwiched between the inner peripheral surface of the strip-shaped transparent cover plate 51 and the outer peripheral wall surface of the cylindrical body 10.

[0026] The lighting lamp 60 includes a lamp body and a lampshade 61 connected to the lower end of the lamp body. The light source 62 of the lamp body is located at the lower end of the lamp body and inside the lampshade 61. A connecting lug 601 protrudes from the outer periphery of the lamp body. The outer end of the connecting lug 601 is detachably connected to the upper hole of the connecting piece 602. A mounting screw 603 passes through the upper hole of the connecting piece 602 and is screwed into the connecting lug 601 to fix the upper end of the connecting piece 602. The lower hole of the connecting piece 602 is fitted onto the screw of the bolt assembly 122 and locked by the nut of the bolt assembly 122. A mounting ring 121 is nested around the periphery of the transparent plate 123. The bolt assembly 122 is locked between the mounting ring 121 and the top of the metal can. Alternatively, a flange 1201 can be installed inside the viewing hole, and the mounting ring 121 is locked to the flange 1201 by the bolt assembly 122.

[0027] Furthermore, the cylindrical body 10 of the metal can is provided with multiple sets of support feet on its outer periphery. Preferably, there are three sets of support feet, evenly spaced along the outer periphery of the cylindrical body 10. Each set of support feet includes a support casting 20 and an arc-shaped welded plate 30. The viewing window 101 and the corresponding viewing window mounting component 50 are located in the area between two adjacent sets of support feet, specifically in the area between two adjacent arc-shaped welded plates 30. Both the support casting 20 and the arc-shaped welded plate 30 are made of metal. In actual manufacturing, it is convenient to select the size of the arc-shaped welded plate 30 as needed, such as the arc width, height, and plate thickness. The height of the arc-shaped welded plate 30 is 0.3 to 0.4 times the height of the outer periphery of the cylindrical body 10, and the plate thickness of the arc-shaped welded plate 30 is usually greater than the wall thickness of the cylindrical body 10, preferably 1.2 to 2 times. The inner side of the arc-shaped welding plate 30 is welded to the outer peripheral side of the cylindrical body 10. The inner side of the arc-shaped welding plate 30 has an inner arc surface, and the curvature of the inner arc surface matches that of the outer peripheral side of the cylindrical body 10. Conical solder portions 40 are welded to the arc-shaped ends of the arc-shaped welding plate 30, respectively. The conical solder portions 40 are welded to the arc-shaped end faces of the arc-shaped welding plate 30 and the outer peripheral side of the cylindrical body 10. The outer sides of the conical solder portions 40 extend obliquely from the outer edges of the arc-shaped end faces of the arc-shaped welding plate 30 to the outer peripheral side of the cylindrical body 10. Preferably, the welds around the four perimeters of the arc-shaped welding plate 30 are designed to extend obliquely and gradually transition, that is, the upper and lower outer edges of the arc-shaped welding plate 30 also extend obliquely to the outer peripheral side of the cylindrical body 10. The peripheral surface of the support casting 20 is composed of an inner surface and two inclined surfaces connecting the two sides of the inner surface. The two inclined surfaces converge at the outward end to form a V-shaped angle, thus making the cross-section of the support casting 20 triangular (or approximately triangular) to improve its performance under axial pressure. The upper inner surface of the support casting 20 is welded to the outer surface of the arc-shaped welding plate 30. The lower end of the support casting 20 is integrally connected to a mounting base plate 21, which has locking holes for anchor bolts to secure it to the ground.

[0028] Because an arc-shaped welding plate is welded to the outer circumference of the cylindrical body, it essentially supports the entire metal tank in the middle section, rather than the bottom as in traditional technology. This allows for more direct load transfer on the outer circumference of the cylindrical body, reducing stress in the end cap welds. Furthermore, welding and installation are easier. Using the mounting base plate as a reference point, the upper position of the support casting 20 can be adjusted relative to the arc-shaped welding plate, allowing for vertical adjustment. Similarly, the vertical position of the arc-shaped welding plate can also be adjusted when welding it to the outer circumference of the cylindrical body. Therefore, the same support casting and arc-shaped welding plate can be adjusted within a certain range to meet the required support height, improving processing and installation flexibility and versatility, and satisfying installation requirements for various support heights. Additionally, this structure uses three-point circumferential support, replacing the traditional four-legged bottom support, saving one leg and reducing costs.

[0029] The key design feature of this invention lies in its ingenious use of existing top viewing holes to cleverly incorporate lighting, creating a permanent, dedicated lighting device that points inwards from the reactor. This transforms a previously handheld, temporary lighting tool into a permanent or semi-permanent functional component integrated into the reactor, freeing up workers' hands, improving operational efficiency and safety (especially when simultaneous operation or recording is required), providing convenience to workers, avoiding damage to the original reactor structure, reducing manufacturing costs, and simplifying the installation process. This achieves minimal alteration to the original reactor structure, while modifying the cylindrical body and using multiple staggered viewing windows to ensure a comprehensive observation range while maximizing the structural strength and pressure-bearing capacity of the reactor sidewalls.

[0030] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
