Description

Technical Field

[0001] The utility model relates to the field of high-pressure reaction kettles, in particular to an explosion-proof high-pressure reaction kettle. Background Art

[0002] A high-pressure reaction kettle is a device used for high-temperature and high-pressure chemical reactions, usually used in laboratories or industrial production. It can provide the high-temperature and high-pressure environment required for the reaction and can collect parameter data such as pressure and temperature during this process.

[0003] Chinese Patent Publication No. CN213966468U discloses a safe high-pressure reaction kettle, including an explosion-proof box. A placement plate is fixedly connected to the inner cavity of the explosion-proof box. A reaction kettle body is fixedly connected to the top of the placement plate. A pressure gauge is fixedly connected to the left side of the top of the reaction kettle body. A feed valve is communicated with the right side of the top of the reaction kettle body. A discharge valve is communicated with the bottom of the reaction kettle body. The bottom end of the discharge valve sequentially penetrates through the placement plate and the explosion-proof box and extends to the bottom of the explosion-proof box. A safety valve is fixedly connected to the left side of the top of the reaction kettle body. This reaction kettle has the advantage of good protection, and solves the problem that the existing high-pressure reaction kettle usually does not have a protection structure on its surface during use, resulting in the material spraying out from the rupture when the inner cavity of the reaction kettle is over-temperature and over-pressure, which is likely to cause fire and explosion accidents, thus reducing the safety of the high-pressure reaction kettle.

[0004] However, the above technical solution has the following deficiencies: When using this reaction kettle, it is necessary to manually open the cover plate. After the raw materials are added, the cover plate is covered, and then the cover plate and the explosion-proof box are tightened with multiple bolts. This is not only troublesome to operate and inconvenient to use, but also when the internal pressure of the reaction kettle is too high for exhaust, the temperature inside the explosion-proof box changes, and water mist will form on the surface of the observation window, making it difficult to see the reading of the pressure gauge. Summary of the Utility Model

[0005] The purpose of the present utility model is to address the problems in the background art and propose an explosion-proof high-pressure reaction kettle, which can solve the problem of cumbersome opening and closing operations of the cover plate, improve the protection effect of the cover plate, and solve the problem of water mist on the observation window.

[0006] The technical solution of the utility model is an explosion-proof high-pressure reactor, which includes an explosion-proof box and a control device; a reactor body is arranged inside the explosion-proof box, and two symmetrically distributed top covers are arranged on the top of the explosion-proof box; the control device includes two vertically distributed vertical plates and a driving mechanism arranged on the vertical plates and driving the top cover to move horizontally. The driving mechanism includes a motor arranged on one side vertical plate, a bidirectional threaded rod horizontally arranged and rotatably connected to the vertical plate, two moving frames symmetrically distributed left and right on the bidirectional threaded rod, a connecting rod for connecting the moving frame and the top cover, and a fixed rod horizontally arranged on the vertical plate. The motor is drivingly connected to the bidirectional threaded rod, the moving frame is threadedly connected to the bidirectional threaded rod, and the moving frame is slidably connected to the fixed rod.

[0007] Preferably, an installation cover is arranged on the top of the reactor body. A plurality of bolts arranged in a circular array are arranged on the installation cover. The bolts are threadedly connected to the reactor body. A pressure gauge, a gas guide pipe and a feed pipe are arranged on the installation cover. A pressure valve is arranged on the gas guide pipe, and a sealing cover is arranged at the feed port of the feed pipe.

[0008] Preferably, a discharge pipe is arranged at the bottom end of the reactor body. A discharge valve is arranged on the discharge pipe, and the discharge pipe penetrates through the explosion-proof box.

[0009] Preferably, two front and rear distributed limit blocks are arranged on the reactor body, and two limit slots for the limit blocks to insert are arranged at the bottom of the explosion-proof box.

[0010] Preferably, an observation window and a controller are arranged on the explosion-proof box. A cleaning component is arranged on one side top cover, and the dial of the pressure gauge faces the observation window.

[0011] Preferably, the cleaning component includes a sliding rod vertically distributed and slidably connected to the top cover, a pressing block and a wiping plate respectively arranged at both ends of the sliding rod, a spring sleeved outside the sliding rod and abutting against the pressing block and the top cover at both ends respectively, and a guiding rod vertically arranged on the top cover.

By tightly pressing the explosion-proof box with the top cover, not only can the protection effect of the explosion-proof box be improved, but also it is convenient and fast when it is necessary to open the explosion-proof box to add raw materials, avoiding the low efficiency and large workload of disassembling multiple threaded fasteners.

[0015] 2.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Embodiment 1

[0022] As Figures 1-4 shown, an explosion-proof high-pressure reaction kettle proposed in this embodiment includes an explosion-proof box 1 and a control device; a reaction kettle body 2 is arranged inside the explosion-proof box 1, and two symmetrically distributed top covers 3 are arranged on the top of the explosion-proof box 1; the control device includes two horizontally distributed vertical plates 4 and a driving mechanism arranged on the vertical plates 4 and driving the top cover 3 to move horizontally. The driving mechanism includes a motor 5 arranged on one vertical plate 4, a bidirectional threaded rod 6 horizontally arranged and rotatably connected to the vertical plate 4, two moving frames 7 symmetrically distributed left and right on the bidirectional threaded rod 6, a connecting rod 8 for connecting the moving frame 7 and the top cover 3, and a fixed rod 9 horizontally arranged on the vertical plate 4. The motor 5 and the bidirectional threaded rod 6 are drivingly connected, the moving frame 7 and the bidirectional threaded rod 6 are threadedly connected, the moving frame 7 and the fixed rod 9 are slidably connected. The bidirectional threaded rod 6 is provided with a first threaded portion and a second threaded portion with opposite thread directions, and the two moving frames 7 are respectively threadedly connected to the first threaded portion and the second threaded portion, and the moving directions of the two moving frames 7 are close to each other or away from each other.

[0023] A lifting mechanism is arranged below the vertical plate 4. The lifting mechanism includes a fixed seat 27, a hydraulic cylinder 28 arranged inside the fixed seat 27, and a support plate 29 drivingly connected to the hydraulic cylinder 28. The vertical plate 4 is arranged on the support plate 29.

[0024] In this embodiment, after the raw materials are added to the reaction kettle, the hydraulic cylinder 28 is started to drive the support plate 29 to rise. The support plate 29 drives the vertical plate 4 to rise. After reaching the highest position, the rise stops. Then, the motor 5 is started to drive the bidirectional threaded rod 6 to rotate. The bidirectional threaded rod 6 is screwed with the moving frame 7. Under the guiding action of the fixed rod 9, the two moving frames 7 approach each other. When the top cover 3 moves to a certain position, the hydraulic cylinder 28 drives the support plate 29 to descend to the lowest position until the two top covers 3 cover the upper part of the explosion-proof box 1. Since the inner side walls of the two top covers 3 tightly press the explosion-proof box 1, it can not only improve the protection effect of the explosion-proof box 1, but also be convenient to operate when the explosion-proof box 1 needs to be opened for adding raw materials, avoiding disassembling multiple threaded fasteners, with simple operation and convenient use.

[0025] Embodiment Two

[0026] As Figure 2 and Figure 3 shown, a kind of explosion-proof high-pressure reaction kettle proposed in this embodiment, compared with Embodiment One, in this embodiment, an installation cover 10 is arranged on the top of the reaction kettle body 2. A plurality of bolts 11 arranged in a circular array are arranged on the installation cover 10. The bolts 11 are threadedly connected to the reaction kettle body 2. A pressure gauge 12, a gas guide pipe 13 and a feed pipe 15 are arranged on the installation cover 10. A pressure valve 14 is arranged on the gas guide pipe 13. A sealing cover 16 is arranged at the feed port of the feed pipe 15. A discharge pipe 17 is arranged at the bottom end of the reaction kettle body 2. A discharge valve 18 is arranged on the discharge pipe 17. The discharge pipe 17 passes through the explosion-proof box 1.

[0027] An observation window 20 and a controller 21 are arranged on the explosion-proof box 1. A cleaning component is arranged on one side of the top cover 3. The dial of the pressure gauge 12 faces the observation window 20. The cleaning component includes a slide rod 22 vertically distributed and slidably connected to the top cover 3, a pressing block 25 and a wiping plate 24 respectively arranged at both ends of the slide rod 22, a spring 23 sleeved outside the slide rod 22 and abutting against the pressing block 25 and the top cover 3 at both ends respectively, and a guide rod 26 vertically arranged on the top cover 3. The pressing block 25 is slidably connected to the guide rod 26. The guide rod 26 is used to limit the moving direction of the slide rod 22. The controller 21 is used to control the opening and closing of each valve, as well as the driving of the motor 5 and the hydraulic cylinder 28.

[0028] In this embodiment, the mounting cover 10 and the reactor body 2 are fastened with bolts 11 to ensure that the reactor body 2 is in a sealed state during the reaction. The pressure gauge 12 is observed through the observation window 20 to determine the pressure inside the reactor body 2. When the pressure value exceeds the safety threshold, the controller 21 will control the pneumatic valve 14 to open to adjust the pressure inside the reactor body 2 and avoid dangerous situations. After the reaction is completed, the discharge valve 18 is opened to discharge the product from the discharge pipe 17.

[0029] When the temperature inside the explosion-proof box 1 changes, a small amount of water mist may form on the surface of the observation window 20, affecting the reading of the pressure gauge 12. By pressing down the pressing block 25, the sliding rod 22 slides downward. The sliding rod 22 drives the wiping plate 24 to wipe the observation window 20. When the pressing block 25 is released, the sliding rod 22 will slide upward under the action of the spring 23. Then, by repeatedly pressing the pressing block 25, the water mist on the surface of the observation window 20 can be wiped off to ensure the clarity of observation, which has good practicability.

[0030] Embodiment Three

[0031] As Figure 3 and Figure 4 shown, an explosion-proof high-pressure reactor proposed in this embodiment, compared with Embodiment One, in this embodiment, two limiting blocks 19 are arranged on the reactor body 2 in a front-back distribution, and two limiting grooves for the limiting blocks 19 to insert are arranged at the bottom of the explosion-proof box 1. In this embodiment, the limiting grooves are used to position the reactor body 2 when it is installed in the explosion-proof box 1. At the same time, the embedded installation method of the explosion-proof box 1 for the bottom of the reactor body 2 can play a role in protection and reinforcement.

[0032] The above has described in detail the embodiments of the present invention in conjunction with the drawings. However, the present invention is not limited to this.
