Description

Technical Field

[0001] This invention relates to the field of compound synthesis furnace technology, and more particularly to a lifting synthesis furnace. Background Technology

[0002] Boron trichloride (BCl3) is an inorganic compound with a boiling point of only 12.5°C, making it a readily liquefied gas at room temperature. It is primarily used as a catalyst in organic reactions such as esterification, alkylation, polymerization, isomerization, sulfonation, and nitration. It can also be used as an antioxidant in magnesium casting and alloy production, as a main raw material for the preparation of boron halides, elemental boron, boranes, and sodium borohydride, and is also used in the electronics industry.

[0003] The current method for producing boron trichloride uses boric acid and chlorine gas as raw materials in a high-temperature, closed reactor. After the boric acid is placed in the reaction vessel, it needs to be moved to a furnace, where chlorine gas is then introduced for heating. Moving the reaction vessel relative to the furnace is very cumbersome; it must not only be moved to the side of the furnace but also lifted and placed inside. Manual handling is time-consuming and labor-intensive due to the long length and weight of the reaction vessel. Furthermore, to prepare a large number of compounds at once, multiple sets of reaction vessels are usually set up to improve efficiency, but the installation and removal of these multiple sets are inconvenient, resulting in low compound preparation efficiency and impacting economic benefits. Summary of the Invention

[0004] To address the aforementioned problems, the present invention aims to provide a lifting synthesis furnace. When installing a reaction tube, the furnace can be moved to the side of the furnace via a moving frame, then lifted by a lifting mechanism, and finally moved to the top of the furnace by a travel mechanism. The lifting mechanism then lowers the reaction tube into the furnace. When removing the reaction tube, the process is reversed, thereby enabling rapid installation and removal of the reaction tube and significantly improving production efficiency.

[0024] The present invention, by adopting the above technical solution, has the following beneficial effects:

[0025] ① The lower part of the frame forms the synthesis furnace box. A lifting mechanism is installed on the frame, which includes a traction machine, a traction rope, and multiple pulleys. The traction rope enters the frame from the top to hoist the reaction tube assembly. Specifically, the reaction tube assembly is mounted on the stroke assembly. The traction rope lifts the stroke assembly through the support pulleys. The reasonable arrangement of multiple sets of guide pulleys ensures that the traction rope runs smoothly and is evenly stressed, improving the stability and accuracy of the lifting process. The traction machine's rope winding and unwinding allow the stroke assembly and reaction tube assembly to move up and down within the lifting space, enabling the reaction tube assembly to be installed longitudinally onto or removed from the heating chamber. The reaction tube assembly is mounted on a receiving plate connected to the first slider in the stroke mechanism. The stroke mechanism drives the receiving plate to move back and forth, thereby moving the reaction tube assembly relative to the synthesis furnace. This allows the reaction tube assembly to be moved directly above the moving frame. After being lowered by the traction rope, the moving frame receives and removes the reaction tube assembly, enabling rapid installation, disassembly, and movement of the reaction tube assembly. This facilitates maintenance and replacement of the reaction tube, improves equipment efficiency and safety, and increases production efficiency.

[0026] ② The stroke mechanism adopts a combination of rodless cylinder and slider, which saves installation space, achieves precise positioning and smooth pushing and pulling, facilitates the insertion and removal of reaction tubes, and improves operating efficiency and automation.

[0027] ③ The second sliders on both sides of the rodless cylinder cooperate with the first guide rail, and the third slider at the bottom of the receiving plate cooperates with the second guide rail, making the forward and backward translation and up and down movement of the reaction tube more stable.

[0050] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0053] like Figures 1-20 The lifting synthesis furnace shown includes:

[0054] Synthetic furnace frame, which includes a frame 1, a synthetic furnace box 2 formed at the lower part of the frame 1, a lifting space 3 formed above the synthetic furnace box 2 within the frame 1, multiple rows of assembly holes 4 provided at the upper end of the synthetic furnace box 2, and a heating chamber communicating with the assembly holes 4 formed inside the synthetic furnace box 2.

[0055] The reaction tube assembly includes at least a reaction tube 5 that can extend into the heating chamber through the assembly hole;

[0056] The lifting mechanism, installed on the frame 1, is suitable for moving the reaction tube assembly and the stroke mechanism up and down to load multiple reaction tubes 5 into the heating chamber, or to move multiple reaction tubes 5 from the heating chamber into the lifting space 3.

[0057] The travel mechanism, installed on the lifting mechanism, is used to support the reaction tube assembly and drive the reaction tube assembly to move back and forth relative to the lifting mechanism;

[0058] The movable frame 6 is attached to the front side of the synthesis furnace box 2 and is suitable for receiving the reaction tube assembly and pushing it out or into the frame 1.

[0059] In the above technical solution, a synthesis furnace body is provided on the synthesis furnace frame, and a heating chamber is formed inside the synthesis furnace body. Multiple reaction tubes of the reaction tube assembly can extend into the heating chamber along the assembly holes. A movable frame can push the assembled reaction tube assembly into or out of the frame of the synthesis furnace frame. A stroke mechanism can support and drive the reaction tube assembly to move back and forth, while a lifting mechanism can move the stroke mechanism and the reaction tube assembly up and down. Thus, after the reaction tube assembly is mounted on the movable frame, the movable frame is pushed to be against the side of the synthesis furnace body. The lifting mechanism moves upward so that the stroke mechanism supports the reaction tube assembly and drives the reaction tube assembly to move upward above the synthesis furnace body. Then, the stroke mechanism moves it to the top of the synthesis furnace body, and the lifting mechanism moves the reaction tube assembly downward so that the reaction tubes extend into the heating chamber along the assembly holes. When removing, the above steps are reversed so that the reacted reaction tube assembly can be mounted on the movable frame and pushed away. This achieves rapid installation, disassembly, and movement of the reaction tube assembly, avoiding the inconvenience of manual handling, facilitating maintenance and replacement of reaction tubes, improving equipment efficiency and safety, and increasing production efficiency.

[0060] Furthermore, the lifting mechanism includes a traction machine 7 disposed on the lower part of the side wall of the frame 1. A first guide pulley 8 is vertically arranged above the traction machine 7 on the side wall of the frame 1. A second guide pulley 9 is vertically arranged above the first guide pulley 8 at the upper end of the frame 1. A third guide pulley 10 is horizontally arranged to the side of the second guide pulley 9. A fourth guide pulley 11 is horizontally arranged to the side of the third guide pulley 10. A fifth guide pulley is horizontally arranged at the four corners of the top of the frame 1. A sixth guide pulley is vertically arranged to the side of each fifth guide pulley. The end of the traction rope 100 is fixed to the top of the frame 1. A seventh guide pulley 14 is vertically arranged in front of the end of the traction rope 100.

[0061] Each sixth guide pulley has a guide hole 15 communicating with the lifting space 3 on its side. Below each guide hole 15, a support pulley 16 fixed to the travel mechanism and arranged vertically is provided in the lifting space 3. One side of the traction rope 100 is wound around the traction machine 7, and the other side extends through the first guide pulley 8, the second guide pulley 9, the third guide pulley 10, the fourth guide pulley 11, the fifth guide pulley 12A, the sixth guide pulley 13A, two support pulleys 16, the sixth guide pulley 13B, the fifth guide pulley 12B, the fifth guide pulley 12C, the sixth guide pulley 13C, two support pulleys 16, the sixth guide pulley 13D, the fifth guide pulley 12D, and the seventh guide pulley 14.

[0062] In the above technical solution, the lifting and lowering of the travel mechanism and the reaction tube assembly is achieved by the traction machine winding and releasing the traction rope. The travel mechanism has fixed support pulleys on both sides. The traction rope winds through the support pulleys to suspend the travel mechanism in the lifting space. Multiple sets of guide pulleys are also reasonably arranged on the side walls and top of the frame to make the traction rope run smoothly and be evenly stressed, thereby improving the stability and accuracy of the reaction tube assembly during the lifting process, reducing rope wear, and extending the service life of the equipment.

[0063] It should be noted that in this case, the support pulley is located on the outside of the stroke mechanism. Two support pulleys correspond to one side of the stroke mechanism to ensure the stability of the stroke mechanism. The support pulley is preferably located directly below the guide hole so that the traction rope is vertical to maintain the stability of the force.

[0064] Furthermore, the vertically arranged guide pulleys are mounted on the frame 1 via a first bracket 17, and the horizontally arranged guide pulleys are mounted on the frame 1 via a second bracket 20. The first bracket 17 includes two L-shaped first fixing frames 18, the bottoms of which are connected by a first connecting piece 19, and the vertically arranged guide pulleys are installed between the two first fixing frames 18. The second bracket 20 includes two L-shaped second fixing frames 21, the upper parts of which are connected by a second connecting piece 22. One side edge of the second connecting piece 22 is provided with an L-shaped flap 23, and the horizontally arranged guide pulleys are installed between the second connecting piece 22 and the flap 23. The traction rope 100 passes between the flap 23 and the horizontally arranged guide pulleys. In this technical solution, the vertically arranged guide pulleys are mounted on the frame via the first bracket, and they are installed between the two first fixing frames of the first bracket, which can effectively prevent them from detaching to the left or right. The transversely arranged guide pulleys are mounted on the frame via a second bracket, positioned between the second connecting plate and the flapper. This effectively prevents them from detaching vertically. Furthermore, the traction rope passes between the flapper and the transversely arranged guide pulleys, ensuring that the traction rope does not detach during lateral movement. In addition, the modular bracket structure facilitates the installation and adjustment of the guide pulleys, enhancing structural rigidity and stability. It also facilitates maintenance and replacement of the guide pulleys, improving the maintainability of the equipment.

[0065] Furthermore, the stroke mechanism includes rodless cylinders 24 disposed on both sides of the reaction tube assembly and a first slider 25 mounted on the rodless cylinders 24. An mounting plate 26 is fixedly provided on the outer wall of the rodless cylinders 24. A connecting block 27 connected to the support pulley 16 is provided on the outer wall of the mounting plate 26. An L-shaped fixing plate 28 is provided on the outer wall of the first slider 25. A receiving plate 29 is provided at the lower end of the fixing plate 28. The reaction tube assembly is mounted on the receiving plate 29. In this technical solution, the stroke mechanism adopts a combination of a rodless cylinder and a slider to reduce installation space. A mounting plate is fixed on the outer wall of the rodless cylinder. A connecting block is fixed on the mounting plate and connected to the support pulley, so that the traction rope can be wound around and lift the rodless cylinder. A fixing plate is fixed on the outer wall of the slider, and a receiving plate is provided at the lower end of the fixing plate. The reaction tube assembly can be mounted on the receiving plate. Therefore, the rodless cylinder can drive the reaction tube assembly mounted on the receiving plate to move back and forth, achieving precise positioning and smooth pushing and pulling, which facilitates the loading and unloading of the reaction tube and improves the operating efficiency and automation level.

[0066] Furthermore, multiple second sliders 30 are provided on both sides of the outer wall of the mounting plate 26, and a first guide rail 31 that cooperates with the second sliders 30 is provided on the inner wall of the frame 1. In this technical solution, the mounting plate of the rodless cylinder is provided with second sliders on both sides, and the inner walls of both sides of the frame are provided with first guide rails that cooperate with the second sliders. When the rodless cylinder is lifted and moved up and down, the second sliders move on the first guide rails, thereby ensuring that the stroke mechanism remains stable during the lifting process, preventing shaking and deviation, and improving the safety and reliability of equipment operation.

[0067] Furthermore, a guide plate 32 is formed on the lower inner wall of the mounting plate 26, and a second guide rail 33 is formed on the outer upper end of the guide plate 32. Multiple third sliders 34 that cooperate with the second guide rail 33 are provided at the bottom of the receiving plate 29. In this technical solution, a guide plate is provided on the inner wall of the rodless cylinder below the receiving plate, and a second guide rail is provided on the guide plate. The bottom of the receiving plate is provided with third sliders that cooperate with the second guide rail. This further optimizes the guiding structure, ensuring that the receiving plate moves smoothly without shaking, enhancing the positioning accuracy and operational stability of the reaction tube assembly. Furthermore, by integrating the receiving plate, guide plate, and rodless cylinder into a single unit, the load-bearing capacity of the receiving plate is increased, and the load on the sliders is reduced.

[0068] Furthermore, the reaction tube assembly includes an assembly block 35. L-shaped limiting blocks 36 are fixedly provided on the front and rear sides of the upper end of the receiving plate 29. A limiting groove 37 is formed between the limiting block 36 and the fixing plate 28. The two sides of the assembly block 35 are adapted to be mounted on the limiting grooves 37 of the two side receiving plates 29. Multiple reaction tubes 5 are passed through the assembly block 35. The upper part of the reaction tube 5 is installed on the assembly block 35 through a flange 38. The reaction tube 5 includes a reaction tube body 39 and an exhaust pipe 40 provided at the lower end of the reaction tube body 39. Multiple vent pipes 41 are provided at the upper end of the reaction tube body 39. Multiple connecting pipes 42 are formed at the lower end of the vent pipes 41, which are respectively connected to the upper inlet of the multiple reaction tubes 5. An air inlet pipe 43 is provided on one side of the vent pipe 41.

[0069] A connecting space is formed below the synthesis furnace box 2. A docking plate 44 is fixedly installed in the connecting space. A ventilation hole 45 is provided on the docking plate 44 corresponding to multiple gas outlet pipes 40. A docking seat 46 is provided above the ventilation hole 45. A docking groove 47 is provided in the middle of the docking seat 46 to be inserted and matched with the gas outlet pipe 40. A gas outlet channel 48 communicating with the ventilation hole 45 is constructed in the docking plate 44. A gas outlet hole 49 with the same as the gas outlet channel 48 is provided on the side wall of the docking plate 44.

[0070] In the above technical solution, the reaction tube assembly includes an assembly block and multiple reaction tubes mounted on the assembly block via flanges. L-shaped limiting blocks are fixed to the upper ends of both sides of the receiving plate. The inner side of the slider, which is higher than the receiving plate, forms a limiting groove with the limiting block to cooperate with the assembly block. That is, one end of the assembly block is supported on the L-shaped limiting block. In this way, the receiving plate can be effectively prevented from moving after receiving the assembly block, thus playing a limiting role. In addition, a vent pipe is set above a row of reaction tubes. Multiple connecting pipes are formed below the vent pipe, which communicate with the bodies of multiple reaction tubes. After gas is introduced into the vent pipe, gas can be introduced into the bodies of multiple reaction tubes through the connecting pipes to carry out the reaction. The gas outlet pipe is connected to the connecting plate below the synthesis furnace box. The connecting plate is provided with a connecting seat to prevent the gas outlet pipe from shaking. A vent hole is provided below the connecting seat. The vent hole is connected to the gas outlet through the gas outlet channel. The gas outlet is connected to an external pipe to collect the compound after the reaction. Furthermore, the vent has an inwardly threaded section for easy connection to external pipes, enabling rapid assembly. The modular design of the reaction tube assembly allows for centralized installation and unified connection of multiple reaction tubes, improving sealing and operational efficiency; the rational design of the venting and exhaust structure facilitates gas transport and collection.

[0071] Furthermore, the front and rear sides of the synthesis furnace body 2 are recessed inward to form grooves 50. The movable frame 6 includes a storage frame 51 and multiple casters 52 disposed at the bottom of the storage frame 51. The storage frame 51 fits into the groove 50, and gaps are formed between the two sides of the storage frame 51 and the receiving plate 29. The upper end of the storage frame 51 is higher than the upper end of the synthesis furnace body 2. In this technical solution, the grooves on both sides of the synthesis furnace body cooperate with the storage frame of the movable frame to prevent the movable frame from moving left and right, while ensuring that the receiving plate and the storage frame can correspond, which facilitates the receiving and transportation of reaction tube components and improves replacement efficiency.

[0072] Furthermore, the synthesis furnace body includes a furnace base 53, a cover plate 54 on the furnace base 53, a furnace cavity 55 is formed inside the furnace base 53, two furnace bodies 56 are assembled inside the furnace cavity 55, a receiving groove 57 is opened on the opposite side of the two furnace bodies 56, the two receiving grooves 57 are assembled to form the heating cavity, multiple partitions 58 are arranged horizontally inside the receiving groove 57, the upper end of the furnace body 56 and the partitions 58 are provided with a first mounting hole 59 that cooperates with the reaction tube body 39, and the lower end of the furnace body 56 is provided with a second mounting hole 60 that cooperates with the gas outlet pipe 40;

[0073] On the inner wall of the furnace body 56, multiple arc-shaped grooves 61 are provided laterally on both sides of the partition 58. The arc-shaped grooves 61 on both sides are joined together to form a clamping hole 62. A heating tube 63 is inserted through the clamping hole 62 and clamped between the two furnace bodies 56. An insulation barrel 64 with an open top is provided on the outer side of the furnace body 56 inside the furnace cavity 55.

[0074] In the above technical solution, two furnace bodies are installed inside the furnace base. Each furnace body has a first mounting hole and a second mounting hole for installing the reaction tube, facilitating the positioning of the reaction tube. A clamping hole is formed between the two furnace bodies for installing the heating tube. Therefore, the heating tube is positioned between the reaction tubes on both sides of the furnace body, simultaneously heating both reaction tubes. An insulation container is used to maintain the temperature, prevent heat loss, and improve heating efficiency.
