Abstract
Description
Technical Field
[0001] This utility model relates to the field of telescopic reactor technology, and in particular to a telescopic reactor with adjustable volume. Background Technology
[0002] In numerous industrial sectors such as chemical, pharmaceutical, and food processing, reaction vessels are crucial pieces of equipment, widely used in processes involving material mixing, heating, cooling, and chemical reactions. Traditional reaction vessels typically have a fixed volume design. However, in actual production processes, the amount of material input is not always constant. Sometimes, due to adjustments in production plans, experimental needs, or limitations in raw material supply, the amount of material to be processed may be relatively small.
[0003] When using a fixed-volume reactor to process a small amount of material, a significant amount of residual space remains within the reactor. This residual space presents several problems. First, reaction efficiency is significantly reduced. Because the material is more dispersed within the larger space, the probability of collisions between reactant molecules decreases, leading to a slower reaction rate. Second, energy waste is severe. To maintain the required temperature, pressure, and other conditions for the reaction, the reactor consumes a large amount of energy. However, a considerable portion of this energy is used for heating or maintaining the environment of the residual space, rather than directly contributing to the material reaction, resulting in unnecessary energy loss. To address these issues, we propose an adjustable-volume telescopic reactor. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable-volume telescopic reactor.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An adjustable-volume telescopic reactor includes two fixed plates. Two moving rails are slidably connected to one side of the fixed plates. A flange is fixed between the two moving rails on the same horizontal plane. A multi-layer metal bellows is connected between the two flanges. A V-shaped polytetrafluoroethylene sealing ring is provided on the inner circumference of the multi-layer metal bellows. The interlayers of the multi-layer metal bellows are filled with high-temperature resistant silicone sealing rings. A folding frame is slidably connected between the two moving rails on the same side. A pushing mechanism is installed on one side of the fixed plates. The pushing mechanism is connected to the folding frame. An upper reactor body is installed at the upper end of one flange, and a lower reactor body is installed at the lower end of the other flange.
[0007] Preferably, both ends of one side of the fixed plate are fixed with fixed rails, and both sides of the movable rail are slidably connected to the fixed rails.
[0008] Preferably, T-shaped sliders are installed at both ends of the folding frame, and two T-shaped sliders on the same side are slidably connected to one end of a moving rail on the same side.
[0009] Preferably, the pushing mechanism includes a fixed block fixed to one side of the fixed plate, a hydraulic cylinder is mounted on the fixed block, a movable block is connected to the end of the piston rod of the hydraulic cylinder, and two rotating rods are rotatably connected to the movable block, with one end of the two rotating rods rotatably connected to the folding frame.
[0010] Preferably, a drive motor is installed at the upper end of the upper vessel, a stirring rod is connected to the end of the output shaft of the drive motor, a feed pipe is connected to one side of the upper end of the upper vessel, and a discharge pipe is connected to one side of the lower end of the lower vessel.
[0011] Preferably, the outer wall of the multilayer metal corrugated pipe is covered with an aluminum silicate fiber insulation layer, and the upper side of the inner wall of the multilayer metal corrugated pipe is sprayed with a polyetheretherketone anti-corrosion coating.
[0012] Preferably, support columns are fixed on both sides of the lower end of the fixing plate.
[0013] During the reaction in this utility model:
[0014] 1. Initial state:
[0015] The adjustable-volume telescopic reactor is in its normal extended state, with the upper and lower bodies connected by multiple layers of metal bellows. At this time, the reactor has a large volume and can hold a large amount of material, while the drive motor, hydraulic cylinder, and other equipment are in standby mode.
[0016] 2. Feeding stage:
[0017] Materials are conveyed into the upper and lower reactor bodies through the feed pipe, and operators can control the amount of material fed according to actual production needs.
[0018] 3. Volume adjustment stage:
[0019] When the amount of material input is small, the pushing mechanism is activated. Specifically, the hydraulic cylinder installed on the fixed block fixed on the fixed plate starts to work. The piston rod of the hydraulic cylinder extends or retracts, driving the moving block connected to it to move. The two rotating rods rotatably connected on the moving block rotate with the movement of the moving block and push the folding frame to move. Since the two ends of the folding frame are slidably connected to the moving rail through T-shaped sliders, the folding frame descends and drives the upper flange to descend. The descent of the flange will squeeze the multi-layer metal bellows, causing it to shrink, thereby reducing the volume of the reactor. At the same time, the drive motor installed on the upper part of the upper reactor body drives the stirring rod to rotate. As the volume of the reactor decreases, the stirring rod descends, which can more effectively stir a small amount of material.
[0020] 4. Reaction stage:
[0021] Under suitable temperature, pressure and other conditions, the materials undergo chemical reactions in the reactor. The V-shaped polytetrafluoroethylene sealing ring inside the multi-layer metal bellows and the high-temperature resistant silicone sealing ring filled between the layers ensure the sealing of the reactor and prevent material leakage. The aluminum silicate fiber insulation layer is wrapped around the outside of the multi-layer metal bellows to reduce heat loss and improve energy utilization efficiency. The polyetheretherketone anti-corrosion coating is sprayed on the upper side of the inner wall of the multi-layer metal bellows to prevent the materials from corroding the inner wall of the reactor.
[0022] 5. Discharge stage:
[0023] After the reaction is complete, open the discharge pipe to discharge the reacted material from the reactor;
[0024] 6. Recovery phase:
[0025] If a large amount of material needs to be processed later, the hydraulic cylinder reverses its direction, causing the folding frame to rise, the multi-layer metal bellows to extend, and the reactor to return to a larger volume state, preparing for the next feeding.
[0026] This utility model has the following advantages:
[0027] 1. The adjustable-volume telescopic reactor can flexibly adjust the volume according to the amount of material, making the material more concentrated in the reactor, increasing the probability of collision between reactant molecules, thereby significantly improving the reaction rate and reaction efficiency. Especially when processing a small amount of material, the stirring rod can more effectively stir the material to ensure that the reaction is fully carried out.
[0028] 2. By reducing the remaining space inside the reactor, unnecessary energy waste is avoided. When heating or maintaining reaction conditions, energy can be applied to the materials more concentratedly, improving energy utilization efficiency and reducing production costs.
[0029] 3. It can adapt to the production needs of different material quantities and has a wider range of applicability. It can play a good role in both large-scale production and small-scale experiments, thus improving the utilization rate of the equipment.
[0030] 4. The sealing structure inside the multi-layer metal bellows and the anti-corrosion coating on the inner wall can effectively prevent material leakage and corrosion of the inner wall of the reactor, protect the equipment from damage, and extend the service life of the equipment.
[0031] In summary, this invention allows for flexible adjustment of the volume according to the amount of material. Especially when processing small amounts of material, the stirring rod can more effectively stir the material, ensuring a full reaction, improving energy efficiency, and reducing production costs. It can play a good role in both large-scale production and small-scale experiments, improving the utilization rate of the equipment. Attached Figure Description

Detailed Implementation
[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0038] Reference Figure 1-4 An adjustable-volume telescopic reactor includes two fixed plates 1. Two moving rails 2 are slidably connected to one side of the fixed plates 1. A high-precision guide rail and slider combination is set at the sliding connection. The linear guide rail is used to reduce frictional resistance and improve the adjustment accuracy.
[0039] A flange 7 is fixed between two moving rails 2 on the same horizontal plane. The flange 7 serves to connect and seal. Its sealing surface can be a tongue and groove sealing surface to enhance the sealing effect and prevent material leakage.
[0040] A multi-layer metal bellows 9 is connected between the two flanges 7. The multi-layer metal bellows 9 has good expansion and contraction performance, which can realize the adjustment of the reactor volume.
[0041] A V-shaped polytetrafluoroethylene sealing ring is provided on the inner side wall of the multi-layer metal bellows 9. The V-shaped structure can better fit the side wall under pressure, enhancing the sealing effect. The high-temperature resistant silicone sealing ring can withstand high temperatures, further improving the sealing performance and reliability of the reactor, making it suitable for high-temperature reaction environments.
[0042] The interlayer of the multilayer metal bellows 9 is filled with high-temperature resistant silicone sealing rings. A folding frame 15 is slidably connected between the two moving rails 2 on the same side. A pushing mechanism is installed on one side of the fixed plate 1. The pushing mechanism is connected to the folding frame 15 and is used to drive the movement of the folding frame 15, thereby realizing the adjustment of the reactor volume.
[0043] The upper vessel body 12 is installed on the upper end of one flange 7, and the lower vessel body 8 is installed on the lower end of the other flange 7. The upper vessel body 12 and the lower vessel body 8 are made of high-quality stainless steel, which has good corrosion resistance and strength and can meet the reaction requirements of different materials.
[0044] Fixed rails 3 are fixed at both ends of one side of the fixed plate 1. The two sides of the moving rail 2 are slidably connected to the fixed rails 3. T-shaped sliders are installed at both ends of the folding frame 15. Two T-shaped sliders on the same side are slidably connected to one end of a moving rail 2 on the same side. The design of the T-shaped sliders enables the folding frame 15 to slide stably on the moving rail 2 and prevents it from derailing.
[0045] The pushing mechanism includes a fixed block 5 fixed to one side of the fixed plate 1. A hydraulic cylinder 4 is installed on the fixed block 5. A moving block is connected to the end of the piston rod of the hydraulic cylinder 4. Two rotating rods 14 are rotatably connected to the moving block. One end of the two rotating rods 14 is rotatably connected to the folding frame 15. The moving block is moved by the extension and retraction of the hydraulic cylinder 4, which in turn causes the rotating rods 14 to rotate and push the folding frame 15 to move, thereby realizing the adjustment of the reactor volume.
[0046] A drive motor 11 is installed at the upper end of the upper vessel 12, and a stirring rod is connected to the end of the output shaft of the drive motor 11. A feed pipe 13 is connected to one side of the upper end of the upper vessel 12, and a discharge pipe 10 is connected to one side of the lower end of the lower vessel 8.
[0047] The outer wall of the multi-layer metal corrugated pipe 9 is covered with an aluminum silicate fiber insulation layer 16, and the inner wall of the multi-layer metal corrugated pipe 9 is sprayed with a polyether ether ketone anti-corrosion coating. The aluminum silicate fiber insulation layer 16 has good thermal insulation performance, which can effectively reduce heat loss and reduce energy consumption. Support columns 6 are fixed on both sides of the lower end of the fixing plate 1.
[0048] During the reaction in this utility model:
[0049] 1. Initial state:
[0050] The adjustable-volume telescopic reactor is in the normal extended state. The upper vessel 12 and the lower vessel 8 are connected by a multi-layer metal bellows 9. At this time, the reactor has a large volume and can hold more materials. The drive motor 11, hydraulic cylinder 4 and other equipment are in standby state.
[0051] 2. Feeding stage:
[0052] Materials are conveyed into the upper vessel 12 and the lower vessel 8 through the feed pipe 13. Operators can control the amount of material fed in according to actual production needs.
[0053] 3. Volume adjustment stage:
[0054] When the amount of material input is small, the pushing mechanism is activated. Specifically, the hydraulic cylinder 4 installed on the fixed block 5 fixed on the fixed plate 1 starts to work. The piston rod of the hydraulic cylinder 4 extends or retracts, driving the moving block connected to it to move. The two rotating rods 14 rotatably connected on the moving block rotate with the movement of the moving block and push the folding frame 15 to move. Since the two ends of the folding frame 15 are slidably connected to the moving rail 2 through T-shaped sliders, the folding frame 15 will drive the upper flange 7 to descend as it descends. The descent of the flange 7 will squeeze the multi-layer metal bellows 9, causing it to shrink, thereby reducing the volume of the reactor. At the same time, the drive motor 11 installed on the upper end of the upper reactor body 12 drives the stirring rod to rotate. As the volume of the reactor decreases, the stirring rod descends, which can more effectively stir a small amount of material.
[0055] 4. Reaction stage:
[0056] Under suitable temperature, pressure and other conditions, the materials undergo chemical reactions in the reactor. The V-shaped polytetrafluoroethylene sealing ring inside the multilayer metal bellows 9 and the high-temperature resistant silicone sealing ring filled between the layers ensure the sealing of the reactor and prevent material leakage. The aluminum silicate fiber insulation layer 16 covers the outside of the multilayer metal bellows 9 to reduce heat loss and improve energy utilization efficiency. The polyether ether ketone anti-corrosion coating is sprayed on the upper side of the inner wall of the multilayer metal bellows 9 to prevent the materials from corroding the inner wall of the reactor.
[0057] 5. Discharge stage:
[0058] After the reaction is complete, open the discharge pipe 10 to discharge the reacted material from the reactor;
[0059] 6. Recovery Phase:
[0060] If a large amount of material needs to be processed later, the hydraulic cylinder 4 reverses its movement, causing the folding frame 15 to rise, the multi-layer metal bellows 9 to extend, and the reactor to return to a larger volume state, preparing for the next feeding.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
