Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, and in particular to a laboratory high-temperature reaction vessel. Background Technology

[0002] A reaction vessel is a sealed container used for chemical, physical, or biological reactions, widely used in chemical, pharmaceutical, food, and materials science fields. Equipped with a stirring device, temperature control system, pressure sensor, and inlet and outlet ports, it allows for precise control of reaction conditions to ensure thorough mixing and efficient reaction. In the research and development of food flavorings, specialized high-temperature laboratory reaction vessels are required. These are typically made of high-strength, high-temperature-resistant materials and possess excellent sealing performance and a precise temperature control system.

[0003] A search revealed Chinese Patent Publication No. CN204699671U, which discloses a chemical laboratory reaction vessel, belonging to the field of chemical equipment. The vessel includes a vessel body with an insulation layer, a base at the bottom, and a lid connected to the top. An electric motor is mounted on the lid, connected to a reducer. A pressure gauge is mounted on the lid, connected to an explosion-proof valve that connects to the vessel body's inner cavity. A high-temperature, high-pressure needle valve is also mounted on the lid, connected to the vessel body via a pipe. A coupling connects the reducer to a drive shaft, which is equipped with a stirrer. The side of the vessel body has a feed inlet and a vacuum port. An internal cooling coil is located inside the vessel body. An electric heating device is located at the lower part of the inner cavity, and a discharge port is located at the bottom. This chemical laboratory reaction vessel allows for thorough and uniform mixing of substances, precise, effective, and convenient temperature control within the reaction vessel, significantly improving reaction efficiency and product quality.

[0004] In the above-mentioned utility model, the reactor is connected to the base, as well as to the lid and the motor. The internal material of the reactor is stirred by the agitator. However, in actual use, when it is necessary to clean or maintain the reactor or the base, the reactor and the base are usually fixed with bolts, which makes the cleaning and maintenance operation cumbersome and prone to incomplete cleaning, affecting the use of the reactor. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a laboratory high-temperature reaction vessel, which aims to improve upon the previous one.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a laboratory high-temperature reactor, comprising a base, an outer shell fixedly connected to the upper surface of the base, a reactor body disposed inside the outer shell, a cover plate disposed on the upper surface of the reactor body, the lower surface of the cover plate disposed on the upper surface of the outer shell, a hollow box fixedly connected to the outer wall of the outer shell, a Z-shaped rod rotatably connected inside the hollow box, a gear fixedly connected to the outer wall of the Z-shaped rod, a rack meshing with the tooth end of the gear, a block fixedly connected to the outer wall of the rack, the outer wall of the block slidably connected inside the hollow box, an L-shaped frame fixedly connected to the upper surface of the rack, a limiting plate fixedly connected to the outer wall of the L-shaped frame, the outer wall of the limiting plate slidably connected inside the cover plate, and a limiting component disposed on the outer wall of the Z-shaped rod.

[0007] The above technical solution utilizes a limiting plate to limit or release the cover plate, thereby limiting or releasing the vessel body. The detachable cover plate facilitates the removal of the vessel body from the interior of the outer shell, allowing for cleaning or maintenance of both the outer shell and the vessel body. By rotating the Z-shaped rod, the gear drives the rack to move downwards. The block slides inside the hollow box, limiting the movement of the rack. The limiting component prevents the Z-shaped rod from rotating to the right. The Z-shaped rod, through the gear and rack, transmits power to the L-shaped frame and the limiting plate.

[0008] As a further description of the above technical solution: The limiting assembly includes a ratchet, the inside of which is fixedly connected to the outer wall of the Z-shaped rod. The teeth of the ratchet are engaged with a pawl, the inside of which is rotatably connected to the outer wall of the hollow box. A spring is fixedly connected to the outer wall of the pawl, and the outer wall of the spring is fixedly connected to the outer wall of the hollow box.

[0009] The above technical solution utilizes the elastic force of spring one to hold the pawl in place and limit the ratchet wheel, allowing the Z-shaped lever to rotate normally to the left and limiting its rotation to the right, thereby achieving self-locking of the Z-shaped lever's rotation.

[0010] As a further description of the above technical solution: The outer wall of the rack is slidably connected to the inside of the hollow box, and the outer wall of the L-shaped frame is slidably connected to the inside of the hollow box.

[0011] The above technical solution utilizes the grooves inside the hollow box to facilitate the movement of the rack through the hollow box, and uses the interior of the hollow box to limit the movement of the L-shaped frame.

[0012] As a further description of the above technical solution: The outer wall of the outer shell is provided with a cooling box, and a hollow block is fixedly connected to the outer wall of the cooling box. The outer wall of the hollow block is slidably connected to the inside of the outer shell.

[0013] The above technical solution utilizes a cooling box installed in the outer shell to cool both sides of the reactor body, preventing localized overheating that could lead to material decomposition.

[0014] As a further description of the above technical solution: The hollow block is internally slidably connected to a T-shaped frame, and the outer wall of the T-shaped frame is fixedly connected to a connecting seat.

[0015] The above technical solution involves using a handheld T-shaped frame to slide inside the hollow block to drive the connecting seat.

[0016] As a further description of the above technical solution: The outer wall of the connecting seat is slidably connected to the inner wall of the hollow block, and a connecting plate is rotatably connected to the outer wall of the connecting seat.

[0017] The above technical solution allows the hollow block's inner wall to limit the movement of the connecting seat, thereby driving the connecting plate.

[0018] As a further description of the above technical solution: The connecting plate is rotatably connected to a fixed seat, and one end of a second spring is fixedly connected to the upper surface of the fixed seat. The other end of the second spring is fixedly connected to the inner wall of the hollow block.

[0019] The above technical solution involves using a connecting plate to move the fixed base, compressing the second spring, and then using the rebound of the second spring to move the fixed base in the opposite direction.

[0020] As a further description of the above technical solution: The outer wall of the fixing seat is slidably connected to the inner wall of the hollow block, and a fixing block is fixedly connected to the lower surface of the fixing seat. The outer wall of the fixing block penetrates the interior of the connecting seat and is slidably connected to the interior of the outer shell.

[0021] The above technical solution uses the inner wall of the hollow block to limit the movement of the fixed seat, and the fixed seat drives the fixed block to move, thereby sliding in and out of the shell.

[0022] This utility model has the following beneficial effects: 1. In this utility model, the reactor body is locked or released by the cooperation between the hollow box, Z-shaped rod, gear, rack, block, L-shaped frame, limiting plate and limiting components, through the cover plate, which reduces the displacement and shaking of the reactor body and enhances the structural stability of the reactor. When cleaning, repairing or replacing the reactor body, the operation is simple and quick, which helps to improve the working efficiency of the laboratory.

[0023] 2. In this utility model, the cooling box can be quickly installed and disassembled through the cooperation between the hollow block, T-shaped frame, connecting seat, connecting plate, fixed seat, spring two and fixed block, which prevents the fragrance inside the reactor from overheating, protects the reactor body and internal components, and facilitates flexible adjustment of the cooling box according to different experimental needs, thereby improving the experimental efficiency of the reactor.

Detailed Implementation

[0026] 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.

[0027] Reference Figure 1 , Figure 2 and Figure 3An embodiment of this utility model provides a laboratory high-temperature reactor, including a base 1, an outer shell 2 fixedly connected to the upper surface of the base 1, a reactor body 3 disposed inside the outer shell 2, a cover plate 4 disposed on the upper surface of the reactor body 3, the lower surface of the cover plate 4 disposed on the upper surface of the outer shell 2, a hollow box 5 fixedly connected to the outer wall of the outer shell 2, a Z-shaped rod 6 rotatably connected inside the hollow box 5, a gear 8 fixedly connected to the outer wall of the Z-shaped rod 6, a rack 9 meshing with the tooth end of the gear 8, a block 10 fixedly connected to the outer wall of the rack 9, the outer wall of the block 10 slidably connected inside the hollow box 5, an L-shaped frame 11 fixedly connected to the upper surface of the rack 9, a limiting plate 20 fixedly connected to the outer wall of the L-shaped frame 11, the outer wall of the limiting plate 20 slidably connected inside the cover plate 4, and a limiting component 7 disposed on the outer wall of the Z-shaped rod 6. Specifically, hollow boxes 5 are provided around the outer shell 2 to enhance the stability of the cover plate 4 installation. The interior of the hollow boxes 5 supports the rotation of the Z-shaped rod 6, thereby supporting the rotation of the gear 8. The block 10 restricts the range of movement of the rack 9, thereby restricting the range of movement of the L-shaped frame 11 and the limiting plate 20. The bottom end of the rack 9 penetrates the interior of the hollow box 5, and the top end of the rack 9 is limited by the block 10 to prevent the rack 9 from shifting to the left or right due to excessive force from the rotation of the gear 8. The rack 9 drives the limiting plate 20 to slide in and out of the cover plate 4 through the L-shaped frame 11, limiting or releasing the installation of the cover plate 4, thereby achieving the detachability of the cover plate 4 and the vessel body 3.

[0028] Reference Figure 2 The limiting component 7 includes a ratchet 701, the ratchet 701 is fixedly connected to the outer wall of the Z-shaped rod 6, the teeth of the ratchet 701 are engaged with a pawl 702, the pawl 702 is rotatably connected to the outer wall of the hollow box 5, and a spring 703 is fixedly connected to the outer wall of the pawl 702, and the outer wall of the spring 703 is fixedly connected to the outer wall of the hollow box 5. Specifically, the pawl 702 and spring 703 restrict the ratchet 701 and the Z-shaped lever 6 from rotating to the right. Only when the pawl 702 is pressed down and squeezed to compress the spring 703, causing the tooth tip of the pawl 702 to leave the tooth tip of the ratchet 701 and no longer restricting the ratchet 701, can the Z-shaped lever 6 rotate to the right.

[0029] Reference Figure 2 The outer wall of the rack 9 is slidably connected to the inside of the hollow box 5, and the outer wall of the L-shaped frame 11 is slidably connected to the inside of the hollow box 5; Specifically, the bottom of the hollow box 5 is provided with a groove for the movement of the rack 9, and the rack 9 is used to support the L-shaped frame 11.

[0030] Reference Figure 3 and Figure 4A cooling box 12 is provided on the outer wall of the outer shell 2. A hollow block 13 is fixedly connected to the outer wall of the cooling box 12. The outer wall of the hollow block 13 is slidably connected to the inside of the outer shell 2. A T-shaped frame 14 is slidably connected to the inside of the hollow block 13. A connecting seat 15 is fixedly connected to the outer wall of the T-shaped frame 14. The outer wall of the connecting seat 15 is slidably connected to the inner wall of the hollow block 13. A connecting plate 16 is rotatably connected to the outer wall of the connecting plate 16. A fixed seat 17 is rotatably connected to the inside of the connecting plate 16. One end of a second spring 18 is fixedly connected to the upper surface of the fixed seat 17. The other end of the second spring 18 is fixedly connected to the inner wall of the hollow block 13. The outer wall of the fixed seat 17 is slidably connected to the inner wall of the hollow block 13. A fixed block 19 is fixedly connected to the lower surface of the fixed seat 17. The outer wall of the fixed block 19 penetrates the inside of the connecting seat 15 and is slidably connected to the inside of the outer shell 2. Specifically, the cooling box 12 is equipped with cooling plates to cool the position installed in the outer shell 2 and cool the vessel body 3 through the outer shell 2. The hollow block 13 restricts the displacement of the T-shaped frame 14. Short rods are provided inside the connecting seat 15 and the fixed seat 17 for the rotation of the connecting plate 16, which facilitates the transmission of the connecting seat 15 to the fixed seat 17. Without external force, the spring 18 holds the fixed block 19 inside the outer shell 2, thereby improving the stability of the cooling box 12 installation. The hollow block 13 restricts the movement of the fixed block 19.

[0031] Working principle: When using this reactor, the reactor body 3 is placed inside the outer shell 2. The cover plate 4 moves downward along the top outer wall of the outer shell 2 to fit the cover plate 4 against the outer shell 2. By rotating the Z-shaped rod 6 to the left, the gear 8 is driven to rotate. After the rack 9 and the block 10 move downward, the L-shaped frame 11 and the limiting plate 20 move downward to press and limit the cover plate 4. The ratchet 701, pawl 702 and spring 703 prevent the limiting plate 20 from fixing the cover plate 4. After the Z-shaped rod 6 rotates to the right, the spices are placed inside the reactor body 3. The eccentric stirring paddle and the pressure relief mechanism are coupled to the top of the reactor body 3 to achieve coupled stirring and improve the stirring efficiency of the spices inside the reactor body 3. Pull the T-shaped frame 14 to move the connecting seat 15 to the left. This moves the fixed seat 17 upward via the connecting plate 16, compressing the second spring 18. The fixed block 19 then moves upward via the fixed seat 17 and enters the interior of the hollow block 13. Holding the cooling box 12 and the hollow block 13, slide the hollow block 13 into the interior of the outer shell 2. Release the T-shaped frame 14. Under the elastic force of the second spring 18, the fixed seat 17 and the fixed block 19 move downward, allowing the fixed block 19 to slide into the interior of the outer shell 2 and limit the hollow block 13 and the cooling box 12. This enables the rapid installation of the cooling box 12, prevents overheating of the internal stirring of the vessel body 3, and cools the sides of the vessel body 3.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
