Description

Technical Field

[0001] This invention relates to the field of vacuum-sealed tube reaction equipment technology, and in particular to an array device and method for simultaneously reacting a large number of quartz tubes, enabling simultaneous and independent reactions in a large number of quartz tubes. Background Technology

[0002] Vacuum sealing tube technology is widely used in fields with stringent requirements for reaction environments, such as inorganic synthesis and organometallic synthesis. It is applied to reactants that are sensitive to air, require high temperature and pressure, or need to be isolated from air, or to reaction scenarios requiring high temperature and pressure while being isolated from air. By creating a closed, inert reaction environment through vacuuming and sealing, it addresses the core technical challenges of open systems susceptible to interference from oxygen and moisture, or the potential for leakage of volatile substances and product contamination.

[0003] However, the vacuum-sealed tube reaction method in existing technologies has several technical drawbacks: First, to prevent the quartz tube from exploding and causing adjacent quartz tubes to explode, resulting in different samples being mixed together, the quartz tubes need to be placed separately. The number of quartz tubes that a single reactor can hold is very limited, and a single sample often requires multiple reactors to operate simultaneously, resulting in a long reaction cycle, extremely low experimental efficiency, and a large consumption of electrical energy. Second, some schemes use asbestos to isolate the quartz tube. Asbestos is toxic and can easily harm the health of experimental personnel. Moreover, after asbestos is filled, the space inside the furnace becomes crowded, and the energy generated during the reaction cannot be effectively dissipated, leading to instability in the reaction system and posing serious safety hazards. Third, the fragments and reactants generated after the quartz tube explodes are difficult to clean up. Small fragments fall into the reactor coils, causing damage to the reactor and significantly increasing experimental costs. Furthermore, experimental personnel are easily cut while cleaning up the fragments, posing a personal safety risk.

[0004] To address the shortcomings of the existing technologies, this invention presents an array device capable of enabling synchronous and independent reactions in a large number of quartz tubes. This device combines the advantages of high efficiency, energy saving, and safety, and provides stable heat preservation, effectively solving many problems in the existing technologies. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a method for simultaneous reaction of large quantities of quartz tubes that is efficient, safe, and energy-saving.

[0006] Another objective of this invention is to provide an array device for simultaneous reaction of a large number of quartz tubes, enabling synchronous and independent reaction of a large number of quartz tubes, improving experimental efficiency, reducing energy consumption, and simultaneously improving the safety and thermal stability of the reaction process, thus solving the problems of difficult cleaning of quartz tube fragments and easy damage to the reactor.

[0007] Another objective of this invention is to provide a working device for the simultaneous reaction of a large number of quartz tubes that is energy-saving, heat-insulating, stable, and reusable.

[0008] The specific technical solution of the novel array device for simultaneous reaction of large quantities of quartz tubes is as follows:

[0009] An array device for simultaneous reaction of large batches of quartz tubes includes a housing, a top cover, a heat insulation layer, and a heat insulation array layer. The housing and top cover are made of high-temperature, long-lasting materials with rounded corners and smooth surfaces to prevent personnel from being scratched and to improve experimental safety. The top cover has a recessed center and extends outwards around the edges. The top cover connects with the housing to form a sealed space. The top cover is easy to open and close and has no risk of slipping during movement, while also avoiding obstruction of opening and closing due to long-term compression and deformation.

[0010] The heat insulation layer is laid at the bottom of the box and serves to prevent fire, insulate, and keep the heat in the room. Asbestos or other low-cost, high-safety materials with equivalent functions can be used.

[0011] The heat-insulating array layer is stacked on top of the heat-insulating layer, with a reserved gap at the bottom to avoid safety hazards caused by direct contact with the heat-insulating layer; the heat-insulating array layer has several arrayed through holes, which are precisely matched with the quartz tubes to prevent collisions between quartz tubes that could cause breakage. The depth of the through holes is determined by the length of the quartz tube and the height of the reactants inside the tube and is higher than the sealing part of the quartz tube. The thickness of the heat-insulating array layer can completely cover the quartz tube and the reactants inside the tube, providing an independent and stable heat-insulating reaction environment for each quartz tube, enabling a large number of quartz tubes to react independently without interference.

[0012] The array device is divided into a vertical device and a horizontal device. The box and top cover of the vertical device form a fully enclosed structure, which can effectively prevent the quartz tube fragments from flying. The box of the horizontal device has an open structure on the top and bottom, and its top cover is equipped with a buckle structure to realize the protection functions of limiting the heat preservation array layer and preventing the quartz tube fragments from flying. This not only prevents the heat preservation array layer from slipping and the quartz tube from breaking and scratching the experimental personnel during the experiment, but also prevents the fragments of the quartz tube from rushing out of the box and falling into the furnace wire after the quartz tube breaks, thus avoiding damage to the reactor.

[0013] Furthermore, the materials used for the chamber and top cover are selected from one of the following high-temperature, long-life materials: 310S stainless steel, 316 / 316L stainless steel, iron, copper, high manganese steel, corundum, etc., which can be flexibly selected according to the actual operating temperature and experimental conditions. The dimensions of the chamber and top cover can be adapted and adjusted according to the specifications of the reactor and experimental requirements. Among them, 310S stainless steel can be used continuously at 1150℃, meeting the requirements of high-temperature reactions and having a long service life. The top cover structure design can avoid obstruction of opening and closing due to deformation caused by long-term compression. The sealed space formed by the chamber and top cover can not only prevent quartz tube fragments and reactants from entering the furnace wires of the reactor, causing damage to the reactor and increasing experimental costs, but also facilitate the quick cleaning of quartz tube fragments and reactants by experimental personnel. At the same time, experimental personnel are less likely to be cut by fragments, thus improving the experimental safety factor.

[0014] Furthermore, the heat insulation layer is preferably an asbestos layer, or can be replaced with a low-cost, high-safety alternative material layer that has fireproof, heat insulation, and heat preservation functions.

[0015] Furthermore, the thermal insulation array layer is preferably a ceramic fiber layer with a through-hole array. This array layer is non-toxic, has a low thermal conductivity, high thermal insulation efficiency, and stable thermal insulation state. From the perspective of long-term use, it has low cost and can allow a large number of quartz tubes to react simultaneously, reducing power consumption. The diameter of the through holes is adapted to the diameter of the quartz tubes to prevent collisions between the quartz tubes. The depth of the through holes is determined by the length of the quartz tube and the height of the reactants inside the tube and is higher than the sealing part of the quartz tube. The number of arrays of the thermal insulation array layer is determined by the length and width of the box and the diameter of the quartz tubes. The thickness of the thermal insulation array layer is based on completely covering the bottom of the quartz tubes and the reactants. The ceramic fiber array layer can be replaced with rock wool, glass wool, aerogel felt, or asbestos-free sealing gaskets, etc., with equivalent effects, depending on the experimental conditions.

[0016] Furthermore, the buckle structure of the lateral device is a duckbill buckle, or it can be replaced with other buckle structures with the same limiting and anti-splash protection functions, and its material can be flexibly adjusted according to the actual use conditions.

[0017] Furthermore, the vertical and horizontal devices can be used individually or in combination, allowing samples with different or the same ratios and reaction conditions to be placed in the two devices for parallel reactions. This enriches the dimensions of experimental data and improves the accuracy and reliability of experimental results.

[0018] The significant feature of this invention is its high experimental efficiency. The device can achieve simultaneous reactions in a large number of quartz tubes, and can obtain more experimental samples within the same experimental cycle, thus greatly improving experimental efficiency.

[0019] Another significant feature of this invention is its excellent energy-saving performance. Multiple units of this device can be accommodated in a large box-type reactor, enabling simultaneous reaction of a large number of quartz tubes. Compared with traditional methods, the average energy consumption of a single quartz tube is significantly reduced.

[0020] Another significant feature of this invention is its safety and stable thermal insulation. Not only is the thermal insulation effect more stable, but placing the quartz tube in a sealed container effectively prevents fragments from falling into the furnace wires and damaging the reactor in the event of a quartz tube explosion, thus reducing experimental costs. Simultaneously, fragment removal is faster and more convenient, improving the experimental process while preventing personnel from being cut while cleaning fragments, eliminating the safety hazards posed by fragment contact with the body, and significantly improving the safety of experimental operations.

[0021] The beneficial effects of this invention are as follows: While ensuring experimental safety, it enables simultaneous reactions of a large number of quartz tubes, significantly improving experimental efficiency and drastically reducing energy consumption. This invention uses ceramic fiber as the preferred material for the insulation array layer, replacing traditional non-asbestos materials. This fundamentally protects the health and safety of experimental personnel, and the low thermal conductivity of ceramic fiber provides advantages such as high insulation efficiency and stable performance. It also effectively prevents quartz tube fragments from falling into the furnace wires and damaging the reactor, reducing experimental costs. Furthermore, this invention solves the problem of quartz tube fragments being difficult to clean and easily causing scratches to experimental personnel.

[0022] The array device of the present invention also features flexible structure and strong practicality. The material and size of each component can be adapted and adjusted according to actual needs such as experimental conditions, reactor specifications, and quartz tube parameters. It can be assembled and used in various box-type reactors to achieve large-scale reaction. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described below with reference to the accompanying drawings. These are merely examples and should not be construed as limiting the scope of protection of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without inventive effort are within the scope of protection of this invention.

[0036] like Figure 1-4 As shown, the array device for simultaneous reaction of a large number of quartz tubes provided by the present invention includes a top cover 1, a housing 2, a heat insulation layer 3, and a heat-insulating array layer 4. It has both vertical and horizontal structures and can be used alone or in combination for parallel experiments. The array device for simultaneous reaction of a large number of quartz tubes includes a housing 2, a top cover 1, a heat insulation layer 3, and a heat-insulating array layer 4. Figure 1-8 As shown, the array device has two structures: a vertical device and a horizontal device. They can be used alone or in combination for parallel experiments.

[0037] like Figure 1-8As shown, both the chamber body 2 and the top cover 1 are made of 310S stainless steel. 310S stainless steel can be used continuously at 1150℃, meeting the requirements for high-temperature reactions and offering a long service life. The chamber body 2 is formed through a stretching process, and its edges and corners are rounded and smoothly polished to prevent burrs and sharp edges from scratching personnel, thus improving experimental safety. The top cover 1 has a recessed center and extends outwards around the edges, precisely fitting the chamber body 2 to form a sealed space. It is easy and effortless to open and close, and there is no risk of slipping during movement. This structure also prevents deformation of the top cover 1 due to long-term compression, preventing obstruction of opening and closing. The materials of the chamber body 2 and the top cover 1 can also be replaced with high-temperature, long-life materials such as 316 / 316L stainless steel, iron, copper, and high-manganese steel, depending on the actual operating temperature. The dimensions can be adjusted according to the reactor specifications and experimental requirements. Figure 1 As shown, the heat insulation layer 3 is an asbestos layer, which is a thin layer laid on the bottom of the box 2 to play the roles of fire prevention, heat insulation and heat preservation. It can also be replaced with other non-toxic, low-cost and high-safety materials with the same functions to avoid long-term direct contact between toxic materials and the human body.

[0038] like Figure 1 4 and Figure 5 In section 3, the insulation array layer is a ceramic fiber array layer. The ceramic fiber array layer has several arrayed through-holes, the diameter of which precisely matches the diameter of the quartz tube to prevent collisions between quartz tubes that could cause breakage. The depth of the through-holes is determined by the length of the quartz tube and the height of the reactants inside, and is higher than the sealing point of the quartz tube. The number of arrays of the ceramic fiber array layer is determined by the length and width dimensions of the housing 2 and the diameter of the quartz tube. Its thickness completely covers the bottom of the quartz tube and the reactants inside, providing an independent and stable insulation reaction environment for each quartz tube, enabling a large number of quartz tubes to react simultaneously without interference. Ceramic fibers are non-toxic, have low thermal conductivity, high insulation efficiency, and stable insulation performance. Long-term use costs are low, and it can effectively reduce energy consumption. This array layer can also be replaced with materials with equivalent insulation effects, such as rock wool, glass wool, or aerogel felt. Depending on the experimental conditions, the ceramic fiber array layer can also be replaced with materials with equivalent effects, such as rock wool, glass wool, aerogel felt, or asbestos-free sealing gaskets.

[0039] like Figure 1-4 As shown, the box 2 and the top cover 1 of the vertical device form a fully enclosed structure, which can effectively block the fragments from flying after the quartz tube explodes, prevent the fragments from falling into the furnace wires, and facilitate the quick cleaning of fragments by the experimental personnel, thereby improving experimental efficiency.

[0040] like Figure 5-8As shown, the box 2 of the horizontal device has an open structure both vertically and horizontally. A latching structure 4 and 5 are provided between the top cover 1 and the box 2. The latching structures 4 and 5 are duckbill buckles made of 310S stainless steel. The duckbill buckles limit the position of the insulation array layer 3, preventing it from slipping or the quartz tube from breaking and injuring the experimenter during the experiment. Simultaneously, they prevent fragments from the quartz tube from escaping the box 2 after it breaks, avoiding damage to the furnace coils and significantly reducing experimental costs. The latching structures 4 and 5 can also be replaced with other latches of equivalent function, and the material can be flexibly adjusted. The duckbill buckles can also be replaced with other latching structures with equivalent limiting and protective functions, and their material can be flexibly selected according to actual usage conditions.

[0041] Example 1

[0042] A small box-type reactor (power 800W) is selected. Under traditional reaction methods, this reactor can hold a maximum of 8 quartz tubes (diameter 5-15mm, length 100-160mm; in this embodiment, the quartz tube dimensions are the same). The average power consumption of a single quartz tube is 100W. To improve experimental safety, two reactors are used operating simultaneously, with an average power consumption of 200W per quartz tube. Using the array device of this invention, two vertical devices (box 2, length 40cm, width 28cm, height 17cm, center distance between each through-hole 2cm, through-hole array of 20 rows and 14 columns, each device holding 280 quartz tubes) are placed in a large box-type reactor (power 7000W, internal length, width, and height 45cm), which can accommodate 560... One quartz tube is used; then, two small vertical devices (box 2, 40cm long, 8cm wide, and 17cm high, with a 2cm center-to-center distance between through holes, arranged in a 20-row, 4-column array, each device holding 80 quartz tubes) are placed in the remaining space, which can hold 160 quartz tubes. The four devices can hold a total of 820 quartz tubes, with an average energy consumption of only 8.5W per quartz tube. Compared with the traditional method, energy consumption is significantly reduced, experimental efficiency is increased by more than 100 times, and the average power consumption per quartz tube is reduced by more than 10 times.

[0043] Example 2

[0044] according to Figure 1 The design incorporates two vertical devices (box 2, 40cm long, 40cm wide, and 17cm high, with a center-to-center distance of 2cm between each through-hole, arranged in a 20x20 array; each device can hold 400 quartz tubes, each with a diameter of 15mm and a length of 160mm; the quartz tube dimensions are the same in this embodiment) within the aforementioned large box-type reactor (7000W power, internal dimensions 45cm long, width, and height). This allows for the storage of 800 quartz tubes. The remaining space is determined according to… Figure 5The design incorporates a horizontal device (box 2, 40cm long, 40cm wide, and 11cm high, with an open structure on opposite sides; the center-to-center distance between through-holes is 2cm; the through-hole array is arranged in 20 rows and 5 columns on each side; each device can hold 200 quartz tubes). The three devices together can hold 1000 quartz tubes, with an average power consumption of only 7W per tube, achieving low-energy, large-scale experimental reactions.

[0045] Example 3

[0046] In the aforementioned large box-type reactor (power 7000W, internal length, width, and height all 45cm), according to the attached... Figure 5 The design incorporates two horizontal units. The larger horizontal unit, housing 2, measures 42cm in length, 28cm in width, and 42cm in height, with the open side facing outwards. Each through-hole is 2cm apart at the center, and the array of through-holes is arranged in 21 rows and 21 columns on both sides, accommodating 882 quartz tubes (15mm in diameter and 130mm in length). In this embodiment, the quartz tube dimensions are identical. The smaller horizontal unit, housing 2, also measures 42cm in length, 15cm in width, and 28cm in height, with an open structure on the top and bottom surfaces. Each through-hole is 2cm apart at the center, and the array of through-holes is arranged in 7 rows and 21 columns on both sides, accommodating 294 quartz tubes. The remaining space is determined according to… Figure 1 The design places a vertical device (box 2, 42cm long, 15cm wide, and 15cm high, with a center-to-center distance of 2cm between through holes, and an array of 21 rows and 7 columns of through holes), which can hold 147 quartz tubes. The three devices can hold a total of 1323 quartz tubes. The average power consumption of a single quartz tube is only 5.3W, further reducing energy consumption and improving the scale of the experiment.

[0047] The array device of this invention allows for flexible adjustment of the materials and dimensions of each component according to experimental conditions, reactor specifications, and quartz tube parameters, making it highly practical and applicable to various box-type reactors. It enables simultaneous and independent reactions of large batches of quartz tubes, significantly improving experimental efficiency while substantially reducing energy consumption. The use of non-toxic, high-efficiency insulation materials enhances the health and safety of experimental personnel, and ensures stable insulation, guaranteeing the reliability of the reaction system. Multiple layers of protection through the housing, top cover, and snap-fit ​​structure effectively prevent quartz tube fragments from splashing and falling into the reactor coils, avoiding reactor damage, reducing experimental costs, facilitating fragment removal, preventing personnel injuries, and significantly improving the overall safety of the experiment.
