Description

Technical Field

[0001] This utility model belongs to the technical field of pressure vessel equipment, and specifically relates to a reaction pressure vessel that is easy to observe. Background Technology

[0002] Currently, polymerization reactions in polymer production mainly take place in batch reaction vessels. These reaction vessels are key equipment in any chemical production process, determining the quality, variety, and production capacity of chemical products. Equipment affecting polymerization reactions not only determines product quality and production efficiency but also largely determines the safety of the production process. For example, Chinese patent application CN201721131942.9 mentions an improved reaction pressure vessel. This improved vessel uses a symmetrically arranged extended column structure to facilitate observation of the internal reaction and provides good light transmission. However, the pore size of these extended columns is small, resulting in insufficient light transmission and limiting observation to only a portion of the reaction area inside the vessel, leading to poor observation results. Utility Model Content

[0003] The purpose of this invention is to provide a reaction pressure vessel that is easy to observe, in order to solve the problem mentioned in the background art where the diameter of the extended column is small and the observation effect is poor.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a reaction pressure vessel for easy observation, comprising a pressure vessel body and end caps, with end caps welded to both ends of the pressure vessel body, a first extension column provided on one side of the pressure vessel body, and a second extension column provided on the other side of the pressure vessel body, both the first and second extension columns communicating with the pressure vessel body, and an optical fiber spotlight provided inside the first extension column, and an observation tube provided at the end of the second extension column away from the pressure vessel body, with a small hole opened inside the second extension column, and a glass plate movably disposed inside the observation tube.

[0005] Preferably, the end of the first extension column that communicates with the pressure vessel body is angled toward the reaction zone inside the pressure vessel body.

[0006] Preferably, the small hole on the second extension column is aligned with the reaction zone inside the pressure vessel.

[0007] Preferably, both ends of the glass plate are fixed with sliders, and the inner sidewall of the observation tube is symmetrically provided with grooves that match the sliders. A threaded rod is rotatably connected in one of the grooves, and a guide rod is fixed in the other groove. One slider is threadedly connected to the threaded rod, and the other slider is slidably connected to the guide rod.

[0008] Preferably, an adjustment knob is connected to the end of the observation tube away from the second extension column, and the adjustment knob is connected to the threaded rod.

[0009] Preferably, the weld between the end cap and the pressure vessel body is sealed by an end cap reinforcing ring, and ear plates are symmetrically arranged on the side where the end cap reinforcing ring is fixed to the pressure vessel body.

[0010] Preferably, the head reinforcing ring includes a front head reinforcing ring and a rear head reinforcing ring. A feed valve is provided on one side of the head of the front head reinforcing ring via a sealing flange, and a discharge valve is provided on one side of the bottom of the pressure vessel body.

[0011] Preferably, the pressure vessel body is provided with a base at the bottom, and the base is arranged front and back.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) This utility model adds a fiber optic spotlight, an observation tube and a glass plate. The fiber optic spotlight obliquely illuminates the entire reaction area inside the reaction vessel. Then the light enters the observation tube through the small hole on the extension column and presents the picture inside the reaction vessel on the glass plate. This makes it easy to observe the reaction of the entire reaction area inside the reaction vessel directly through the glass plate, which significantly improves the observation effect.

[0014] (2) The distance between the glass plate and the small hole on the extension column in this utility model is adjustable, thereby adjusting the size of the image presented by the small hole on the extension column, thereby magnifying or reducing the image of the reaction area inside the reaction vessel, making it easier to observe clearly and further improving the observation effect.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5 As shown, this utility model provides a technical solution: a reaction pressure vessel for easy observation, including a pressure vessel body 1 and end caps. End caps are welded to both ends of the pressure vessel body 1. A first extension column 2 is provided on one side of the pressure vessel body 1, and a second extension column 3 is provided on the other side of the pressure vessel body 1. Both the first extension column 2 and the second extension column 3 are connected to the pressure vessel body 1. An optical fiber spotlight 4 is provided inside the first extension column 2. The optical fiber spotlight 4 has high temperature resistance, pressure resistance, corrosion resistance, and explosion-proof functions. The end of the first extension column 2 connected to the pressure vessel body 1 is obliquely facing the reaction zone inside the pressure vessel body 1, so that the optical fiber spotlight 4 can obliquely shine on the reaction zone. An observation tube 5 is provided at the end of the second extension column 3 away from the pressure vessel body 1. A small hole 6 is opened inside the second extension column 3. The small hole 6 on the second extension column 3 is directly facing the reaction zone inside the pressure vessel body 1, which facilitates imaging the reaction situation in the reaction zone onto a glass plate 7. A glass plate 7, which is a quartz glass plate, is movably arranged inside the observation tube 5.

[0023] like Figure 1 As shown, the head reinforcing ring 13 includes a front head reinforcing ring and a rear head reinforcing ring. A feed valve 15 is provided on one side of the head of the front head reinforcing ring through a sealing flange. A discharge valve is provided on one side of the bottom of the pressure vessel body 1. The feed and discharge valves facilitate the entry and exit of materials into and out of the pressure vessel body 1.

[0024] In the above technical solution, the reactants are added into the pressure vessel barrel 1 through the feed valve 15 to carry out the reaction. When it is necessary to observe the reaction inside the pressure vessel barrel 1, the light emitted by the fiber optic spotlight 4 illuminates the entire reaction area. Then, the light passes through the small hole 6 on the second extension column 3 to image the reaction in the reaction area onto the glass plate 7, thereby facilitating the direct observation of the reaction in the entire reaction area inside the reaction vessel through the glass plate 7 and improving the observation effect.

[0025] like Figure 3 As shown, both ends of the glass plate 7 are fixed with sliders 8. The inner sidewall of the observation tube 5 is symmetrically provided with grooves 9 that match the sliders 8. A threaded rod 10 is rotatably connected in one groove 9, and a guide rod 11 is fixed in the other groove 9. One slider 8 is threadedly connected to the threaded rod 10, and the other slider 8 is slidably connected to the guide rod 11. The sliders 8, threaded rod 10 and guide rod 11 are all coated with Teflon coating, which has anti-corrosion function.

[0026] like Figure 2 As shown, the end of the observation tube 5 away from the second extension column 3 is connected to an adjustment knob 12. The adjustment knob 12 is connected to the threaded rod 10. The end of the observation tube 5 near the adjustment knob 12 is sealed by a transparent cover plate. Under the premise of ensuring airtightness, it is convenient to view the image on the glass plate 7. The adjustment knob 12 and the observation tube 5 are also connected by a sealing ring for sealed rotation.

[0027] In the above technical solution, when it is necessary to adjust the distance between the glass plate 7 and the small hole 6, the adjustment knob 12 is rotated. The rotation of the adjustment knob 12 drives the threaded rod 10 to rotate. The rotation of the threaded rod 10 engages with one of the sliders 8, thereby converting the circular motion of the threaded rod 10 into the linear motion of one of the sliders 8. This causes the glass plate 7 to move in a direction closer to or further away from the small hole 6, thereby reducing or enlarging the view of the reaction area inside the pressure vessel barrel 1, making it easier to observe clearly and further improving the observation effect.

[0028] like Figure 1 As shown, the weld between the end cap and the pressure vessel body 1 is sealed by the end cap reinforcing ring 13. The side of the end cap reinforcing ring 13 that is fixed to the pressure vessel body 1 is symmetrically provided with ear plates 14. The ear plates 14 are provided with through holes to facilitate the hoisting and installation of the pressure vessel.

[0029] The pressure vessel body 1 is provided with a base 16 at the bottom, and the base 16 is arranged in front and behind, so that the pressure vessel can be supported when it is placed.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
