[0002] Catalytic furnaces are important industrial equipment widely used in chemical reactions and material conversion processes.

[0003] A catalytic furnace typically consists of a reaction chamber, a heating system, a catalyst loading area, and a control system. Inside the reaction chamber, the feed gas undergoes a chemical reaction under the action of a catalyst to produce the desired product.

[0004] A electrically heated catalytic furnace, disclosed in CN216384209U, includes an outer shell, a heat exchanger, and a catalytic reaction chamber. The outer shell has a hollow structure, and an inner shell is fitted inside it. A transverse heat exchanger is located at the upper part of the inner shell, a heating tube is located at the middle of the inner shell, and the catalytic reaction chamber is located at the bottom of the inner shell. An air inlet is provided on the upper side of the outer shell, through which waste gas is sequentially passed through the gaps between the heat exchangers and the heating area of ​​the heating tube, and finally flows out through the catalytic reaction chamber and then out through the air outlet on the bottom side of the outer shell. By sequentially passing the waste gas through the gaps between the heat exchangers and the heating area of ​​the heating tube through the air inlet, and finally flowing out through the catalytic reaction chamber and then out through the air outlet on the bottom side of the outer shell, the catalytic efficiency is improved.

[0005] In the above scheme, the catalytic furnace is a box-type structure, and the replacement of the catalyst is quite troublesome; in addition, the gas entering the catalytic furnace needs to be heated by a heat exchanger and heating tubes, which results in high configuration costs and mediocre catalytic efficiency.

[0039] like Figures 1-15The catalyst furnace shown includes a base 1 and two furnace bodies 2 disposed on the base 1. The upper middle part of the base 1 has a groove 3 that penetrates the base 1 on both the front and rear sides. A tray 40 is fixedly disposed longitudinally in the groove 3. The upper end of the tray 40 forms a storage groove 41 for accommodating reactants. The bottom surface of the storage groove 41 is provided with a plurality of vent holes 42. A cavity communicating with the vent holes 42 is formed in the tray 40. The upper end of the tray 40 is covered with a reaction cylinder 4, which is located between the two furnace bodies 2. The inner sides of the two furnace bodies 2 are respectively constructed with a first cavity and a second cavity. The furnace body 2 includes an outer wall 5, a heat insulation layer 6 and a heating layer 7 from the outside to the inside. The heating layer 7 is provided with a heating element. The top of the reaction cylinder 4 is provided with an air inlet 8, and the side wall of the tray 40 is provided with an air outlet 9 that communicates with the cavity. A vent pipe 10 is spirally provided on the outer wall of the reaction cylinder 4. The air outlet end of the vent pipe 10 extends into the air inlet 8 so that the vent pipe 10 communicates with the reaction cylinder 4. The first cavity and the second cavity are combined to form a heating cavity 11 that cooperates with the reaction cylinder 4 and the vent pipe 10. The two furnace bodies 2 are equipped with lifting components connected to the reaction cylinder 4 above them, which are used to raise the reaction cylinder 4 to open the storage slot 41, or lower the storage slot 41 to close it. The upper ends of the base 1 are provided with first guide rails 12 on both sides, and the lower ends of the furnace body 2 are provided with multiple first sliders 13 that cooperate with the first guide rails 12. The two furnace bodies 2 can slide relative to each other on the first guide rails 12 to open or close the heating chamber 11. When the heating chamber 11 is closed, the two furnace bodies 2 are locked together by multiple locking components.

[0040] In the above technical solution, the catalytic furnace adopts a two-furnace-body split structure. The two furnace bodies slide open on the guide rail, which makes it very easy to expose the reaction cylinder and tray. Alternatively, the two furnace bodies slide close on the guide rail and are locked by a locking component to ensure the heating stability of the reaction cylinder. The lifting component can lift the reaction cylinder and open the storage slot on the tray, making it very convenient to replace the catalyst or pick up the synthesized product after the reaction, thus improving production efficiency.

[0041] Furthermore, a vent pipe is spirally arranged on the surface of the reaction cylinder. When the two side cavities of the furnace body are closed, they fit against the outside of the spirally arranged vent pipe. The heating pipe in the heating layer can heat the gas in the vent pipe and simultaneously heat the reaction cylinder, greatly improving the heating efficiency and eliminating the need for additional heating equipment to preheat the gas. In addition, the reaction cylinder and vent pipe are integrated with the heating chambers in the two furnace bodies, thus further improving the heating efficiency, enhancing the catalytic efficiency of the equipment, and increasing production efficiency.

[0042] Furthermore, the lower side wall of the tray 40 is provided with a gas inlet 14 in the groove 3 opposite to the gas outlet 9; the upper inner wall of the storage slot 41 is provided with a step that circumferentially mates with the lower end of the reaction cylinder 4. In this technical solution, the gas outlet is used for exhaust, and valves are provided on the gas outlet and the gas inlet, which can be opened or closed. If necessary, other gases can be introduced into the reaction cylinder through the gas inlet to carry out the reaction, improving convenience. The groove on the base facilitates the connection of pipes to the tray, and also facilitates the introduction of reaction gases into the inlet of the vent pipe.

[0043] In addition, such as Figure 13 and 14 As shown, the bottoms 101 and 102 of the reaction cylinder cooperate with the steps 100 and 103 on the tray to achieve a double seal and improve the sealing effect.

[0044] Furthermore, each furnace body 2 has a second guide rail 15 on both sides of its upper end, and a square stabilizing frame 16 on top of the furnace body 2. A through hole 43 is formed in the center of the stabilizing frame 16 above the reaction cylinder 4. Second sliders 17, which cooperate with the second guide rails 15, are provided on both sides of the lower end of the stabilizing frame 16. In this technical solution, a stabilizing frame is connected to the upper end of the two furnace bodies. The stabilizing frame is used to stabilize the upper ends of the two furnace bodies when they move relative to each other, making the movement of the two furnace bodies more stable.

[0045] like Figures 7-12 As shown, the lifting assembly includes a traction machine 44 and a traction rope 45 with one end wound around the traction machine 44. The traction machine 44 is located on one side of the upper end of the stabilizing frame 16. Multiple mounting brackets are fixed on both sides of the upper end of the stabilizing frame 16. The multiple mounting brackets include a first mounting bracket 47 close to the traction machine 44 and a second mounting bracket 48 mounted on the same side as the first mounting bracket 47. Two second mounting brackets 48 are correspondingly provided on the side away from the traction machine 44. The side ends of the two second mounting brackets 48 are respectively provided with third mounting brackets 49. The first mounting bracket 47 is provided with two first guide wheels, the second mounting bracket 48 is provided with one first guide wheel, and the first guide wheels are arranged vertically; the third mounting bracket 49 is provided with one second guide wheel, and the second guide wheel is arranged horizontally. The lower side wall of the reaction cylinder 4 is provided with a connecting ring 52. The upper end of the connecting ring 52 is provided with hook groups on both the front and rear sides. The traction rope 45 extends from the traction machine 44 and passes through the first guide wheel A500, the first guide wheel B501, the hook group A530, the first guide wheel C502, the second guide wheel A510, the second guide wheel B511, the first guide wheel D503, the hook group B531, and the first guide wheel E504 in sequence before being fixedly connected to the upper end of the stabilizing frame 16.

[0046] In the above technical solution, the traction machine retracts the traction rope, which moves on each guide wheel to pull the hook assembly on the reaction cylinder to lift the reaction cylinder. When it is necessary to lower the reaction cylinder, the traction machine releases the traction rope, and the reaction cylinder descends to cover the storage slot on the tray. This makes it very convenient to replace the catalyst or pick up the synthesized product after the reaction, thus improving production efficiency.

[0047] Furthermore, anti-detachment blocks 18 are provided on both sides of the first guide rail 12 and the second guide rail 15, and buffer protrusions 19 protrude from the anti-detachment blocks 18 toward the first slider 13 or the second slider 17. In this technical solution, the anti-detachment blocks prevent the upper and lower sliders of the furnace body from detaching and play a shock-absorbing and buffering role, making the furnace body move more smoothly.

[0048] Furthermore, a buffer pad 20 is provided on the middle of the first guide rail 12 on at least one side. In this technical solution, the buffer pad is provided to prevent collision and wear when the two furnace bodies are closed, thus protecting the furnace body.

[0049] Furthermore, the locking component includes a locking plate 21 and a latch 22. The locking plate 21 is fixed to one side of the furnace outer wall 5, and the outer edge of the locking plate 21 is folded to form a first inclined side 23. The latch 22 includes a fixing plate 24 fixed to the other side of the furnace outer wall 5, and a latching block 25 hinged to the fixing plate 24. The front end of the latching block 25 is provided with a second inclined side 26 that engages with the first inclined side 23. A connecting block 27 protrudes from the outer end face of the latching block 25. A locking plate 28 is hinged to the connecting block 27. The locking plate 28 is provided with a locking hole 29. An insert 30 that engages with the locking hole 29 protrudes from the fixing plate 24. In this technical solution, when the two furnace bodies are closed, the two furnace bodies are locked by the cooperation of the first and second inclined sides, ensuring a stable high-temperature environment in the heating chamber. At the same time, the locking plate is locked onto the insert, distributing the lateral force at the hinge between the latching block and the fixing plate, thus improving the reliability of the connection.

[0050] Furthermore, handles 31 are symmetrically provided on the outer walls 5 of the two furnace bodies 2. In this technical solution, the handles facilitate the operation of the furnace body by the staff, improving convenience.

[0051] Furthermore, the base 1 has multiple support legs 32 at its bottom. Each support leg 32 includes a mounting base 33 and rollers 34 mounted on the mounting base 33. A connecting rod 35 is threaded onto the mounting base 33. The lower part of the connecting rod 35 has an adjusting gear 36 and an abutment block 37 arranged sequentially from top to bottom. Under external force, the adjusting gear 36 can drive the connecting rod 35 to rotate relative to the mounting base 33 to adjust the vertical height of the abutment block 37. In this technical solution, the support legs are equipped with rollers. When the adjusting gear adjusts the abutment block to contact the ground, the entire split furnace is stationary on the ground. When the adjusting gear adjusts the abutment block to move upward so that its lower end is lower than the lower end of the roller, the entire split furnace can be pushed away and moved, improving the ease of movement.

[0052] Furthermore, a mounting rod 38 is connected to the lower side wall of the base 1, and an operation panel 39 is provided on the mounting rod 38. In this technical solution, the base includes at least an electrical cabinet 100 at the bottom, and the electrical cabinet 100 is connected to the operation panel via the mounting rod for easy user operation.

[0053] It should be noted that, to ensure a tight seal between the two furnace bodies, a cable clamping groove can be installed on the inner wall of the furnace body corresponding to the traction rope. This ensures a proper seal after the two furnace bodies are joined. Furthermore, after the two furnace bodies are joined, a gap fit is made between the inner wall of the furnace body and the vent pipe to prevent the inner wall of the furnace body from compressing the vent pipe and the traction rope.

[0055] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention.
