[0032] Please combine Figure 1 as well as Figure 2 As shown, the present application first provides a horizontal graphite reactor, including a reactor shell 10, a reactor body 20 and a sliding assembly 30. The reactor shell 10 includes a furnace body 11 and at least one furnace cover 12. The furnace body 11 has a central axis along the horizontal direction. The furnace cover 12 is hinged to the end of the furnace body 11 along the central axis direction of the furnace body 11 to close the furnace body 11; the reactor body 20 is arranged in the furnace body 11, and the reactor body 20 includes a crucible 21, an insulation layer 22 and a heating element 23. The insulation layer 22 is coated on the outside of the crucible 21, and the heating element 23 is coated on the outside of the insulation layer 22; the sliding assembly 30 includes a sliding member and a guide member that are slidably connected to each other, one of the sliding member and the guide member is arranged on the inner wall of the furnace body 11, and the other is arranged on the reactor body 20, so as to movably arrange the reactor body 20 on the furnace body 11 along the central axis direction of the furnace body 11.
[0033] In the present application, the reaction body 20 including the crucible 21, the insulation layer 22 and the heating element 23 is slidably connected to the reactor shell 10 through the sliding assembly 30, so that when accessories need to be replaced or maintenance is required, the reaction body 20 can be slid out of the reactor shell 10 as a whole, which not only improves the convenience and efficiency of operation, but also reduces the difficulty of operation and the risk of damage, and enhances the safety of operation.
[0034] Specifically, the crucible 21 is opened along its own axial direction close to the side of the furnace cover 12, and the insulation layer 22 and the heating element 23 surround the crucible 21 circumferentially with the axis of the crucible 21 as the center, so that after the reaction body 20 slides out of the furnace body 11, there is no need to remove the heating element 23 and the insulation layer 22 from the crucible 21. The staff can directly maintain the inside of the crucible 21 through the opening of the crucible 21, further reducing the difficulty of maintenance.
[0035] Please refer to Figure 4As shown, in some embodiments, the heating element 23 includes a heating element body, an induction coil connector 231 and a coil connector 232. The heating element body is covered by the insulation layer 22. The induction coil connector 231 is electrically connected to the heating element body and is located inside the furnace body 11. The coil connector 232 penetrates the furnace body 11 and is electrically connected to the induction coil connector 231. The induction coil connector 231 and the coil connector 232 are threadedly connected.
[0036] Therefore, the induction coil connector 231 and the coil connecting pipe 232 can be disconnected and disassembled outside the furnace body 11 , so that the reaction body 20 can be slid out of the furnace body 11 later.
[0037] Please combine Figure 1 as well as Figure 2 As shown, in some embodiments, the reaction body 20 also includes an outer shell 24 and a slide 25. The outer shell 24 is covered on the outside of the heating element 23. The slide 25 is fixed to the bottom of the outer shell 24. One of the sliding member and the guide member is arranged on the slide 25.
[0038] Please refer to Figure 2 As shown, in some embodiments, a pull ring 251 is fixed to one end of the slide 25 close to the furnace cover 12 to facilitate pulling out the reaction body 20 as a whole.
[0039] Please combine Figure 1 as well as Figure 2 As shown, in some embodiments, the horizontal graphite reactor further includes a locking assembly 40, which includes a first locking piece 41, a second locking piece 42 and a latch 43. The first locking piece 41 is fixed relative to the reaction body 20, and the second locking piece 42 is fixed relative to the furnace body 11. The latch 43 penetrates the first locking piece 41 and the second locking piece 42 in a vertical direction to limit the relative movement of the reaction body 20 and the furnace body 11.
[0040] The locking assembly 40 is used to fix the reaction body 20 and the furnace body 11 after the reaction body 20 slides into place, thereby increasing the stability of the horizontal graphite reactor of the present application in the working state.
[0041] Of course, other locking components 40, such as bolt fixing, etc., may also be used, as long as the reaction body 20 can be fixed to the furnace body after it is in place, and the present application does not make any further limitations here.
[0042] Please combine Figure 1 as well as Figure 2 As shown, in some embodiments, the first locking member 41 is fixed to one end of the slide 25 close to the furnace cover 12 along the central axis of the furnace body 11; this position is most suitable for human-computer interaction. When the reaction body 20 needs to be disassembled, the locking assembly 40 can be directly unlocked by opening the furnace cover 12.
[0043] Please combine Figure 1 , Figure 2 as well as Figure 3 As shown, in some embodiments, the sliding member includes a plurality of rollers 31 , each roller 31 is rotatably connected to the slide 25 , and the guide member includes a guide rail 32 , which is fixed to the inner wall of the furnace body 11 .
[0044] Through the sliding cooperation between the roller 31 and the guide rail 32, the sliding of the reaction body 20 can be guided, so that the reaction body 20 is more stable and safe during the pulling process, and the shaking and friction are reduced, so that even relatively inexperienced operators can complete the replacement and maintenance work, reducing the difficulty of operation and the dependence on professional skills.
[0045] In some other embodiments, other sliding fitting structures may also be used, which are not listed one by one in this application.
[0046] Please combine Figure 1 , Figure 2 as well as Figure 3 As shown, in some embodiments, a row of rollers 31 are respectively disposed on both sides of the slide 25 , and each row of rollers 31 is disposed at equal intervals along the central axis direction of the furnace body 11 .
[0047] Specifically, four rollers 31 are arranged at equal intervals in each row. Of course, the number and layout of the rollers 31 can be appropriately adjusted according to the actual size and weight of the furnace body, as long as the reaction body 20 can be ensured to be stable and safe during the sliding process.
[0048] In some embodiments, the roller 31 is made of stainless steel, carbon steel, chromium or nickel-based alloy.
[0049] Specifically, the roller 31 is made of 304 stainless steel, tempered carbon steel Q235, 40 chromium, 35CrMo steel, 45 steel, 316 stainless steel or nickel-based alloy, etc., which have strong wear resistance, high temperature resistance and corrosion resistance to improve its service life and reliability.
[0050] More specifically, the wheel body of the roller 31 is made of 304 stainless steel, which has excellent corrosion resistance, high temperature resistance, good strength and toughness. The roller shaft of the roller 31 is made of 45 steel after tempering treatment. The mechanical properties of the 45 steel after quenching and tempering will be further improved. The above materials can ensure the stability and durability of the roller 31 in harsh working environments, and also make the reaction body 20 smoother and safer during sliding loading and unloading.
[0051] Of course, the roller 31 can also be made of other materials according to the use environment and load-bearing requirements. As long as its wear resistance, high temperature resistance and corrosion resistance meet actual needs, this application does not make further limitations here.
[0052] Please combine Figure 1 as well as Figure 4 As shown, in some embodiments, a furnace cover 12 is hingedly connected to each of the two ends of the furnace body 11 along its central axis.
[0053] The furnace covers 12 on both sides can be opened to feed materials or to dismantle the reaction body 20, so as to improve the versatility of the horizontal graphite reactor of the present application.
[0054] Specifically, an independent insulation felt is provided on the furnace cover 12. When the furnace cover 12 is closed, the insulation felt cooperates with the insulation layer 22 to completely cover the crucible 21 to obtain a better insulation effect.
[0055] For more details, please refer to Figure 5 As shown, the furnace cover 12 includes a furnace cover body 121, a fixing frame 122, a thermal insulation felt 123 and a cylinder 124, wherein one end of the cylinder 124 is arranged on the furnace cover body 121, and the other end is connected to the fixing frame 122, the thermal insulation felt 123 is arranged on the side of the fixing frame 122 away from the cylinder 124, and limiting pulleys 122a are arranged on both sides of the fixing frame 122, and a limiting guide rail 121a is fixed on the furnace cover body 121, which is slidably connected to the limiting pulley 122a along the extension and retraction direction of the cylinder 124.
[0056] After the furnace cover 12 is closed, the cylinder 124 is started to squeeze the fixed frame 122 and the insulation felt 123 inward to ensure that the insulation felt 123 is pressed tightly against the insulation layer 22 to prevent heat leakage, and the cooperation between the limiting guide rail 121a and the limiting pulley 122a can limit the moving direction of the fixed frame 122 and improve its movement stability.
[0057] Please combine Figure 1 as well as Figure 3 As shown, in some embodiments, the horizontal graphite reactor further includes a temperature measuring assembly 50, which includes an infrared temperature measuring component 51 and a thermocouple temperature measuring component 52, both of which are disposed in the furnace body 11 and penetrate the furnace body 11 and the reaction body 20 to communicate with the interior of the crucible 21.
[0058] Preferably, the temperature measuring component 50 is located in the center above the crucible 21 to accurately measure the temperature.
[0059] Please combine Figure 1 as well as Figure 3 As shown, in some embodiments, the infrared temperature measuring element 51 includes an infrared temperature measuring body 511, a ball valve 512, a dustproof pipe 513 and a connecting pipe 514;
[0060] The dustproof tube 513 is embedded in the furnace body 11 and protrudes outward from the furnace body 11, and the connecting tube 514 is fixed to the inner wall of the dustproof tube 513 to isolate the space between the connecting tube 514 and the dustproof tube 513 from the outside, and the connecting tube 514 extends inward to communicate with the inside of the crucible 21;
[0061] One end of the ball valve 512 is sealed and fixed to the outer end of the dustproof tube 513 , and the other end of the ball valve 512 is fixed to the infrared temperature measuring body 511 .
[0062] Since pores are provided on the crucible 21, in order to prevent the volatilized gas and powder in the graphitization process from adhering to the quartz glass of the infrared temperature measuring body 511 through the pores and causing the infrared temperature measurement to fail, a connecting pipe 514 and a dustproof pipe 513 are provided to isolate the outer surface of the infrared temperature measuring body 511 from the interior of the furnace body 11 to prevent the above situation from occurring.
[0063] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0064] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
