[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides two technical solutions:

[0029] Figures 1-6 The first embodiment of a mobile detachable high-temperature pit furnace is shown: A mobile detachable high-temperature pit furnace includes a base 1, a handle 101 fixedly connected to the outer wall of the base 1, a double furnace chamber mechanism 2 provided on the base 1, a moving mechanism 3 provided on the base 1, and also includes;

[0030] The double furnace mechanism 2 includes a lower furnace chamber 201 that is snapped onto the outer wall of the base 1, a lower furnace chamber cover 202 that is snapped onto the inner wall of the lower furnace chamber 201, a lower furnace chamber crucible 203 that is fixedly connected to the inner wall of the lower furnace chamber 201, a lower furnace chamber pipe 204 that is fixedly connected to the inner wall of the lower furnace chamber crucible 203, the outer wall of the lower furnace chamber pipe 204 that is fixedly connected to the inner wall of the base 1, a stainless steel load-bearing plate 205 that is fixedly connected to the top of the lower furnace chamber 201, and an upper furnace chamber 206 that is snapped onto the top of the stainless steel load-bearing plate 205.

[0031] An upper furnace pipe 207 is fixedly connected to the inner wall of the upper furnace chamber 206. An upper furnace crucible 208 is fixedly connected to the inner wall of the upper furnace chamber 206. The inner wall of the upper furnace crucible 208 is fixedly connected to the outer wall of the upper furnace pipe 207. The bottom of the upper furnace pipe 207 passes through the inner wall of the lower furnace chamber 201 and extends into the interior of the lower furnace crucible 203. An upper furnace cover 209 is snapped onto the inner wall of the upper furnace chamber 206. A disassembly assembly is provided on the top of the stainless steel load-bearing plate 205.

[0032] The disassembly assembly includes two fixing plates 210 fixedly connected to the outer wall of the stainless steel load-bearing plate 205. Two first telescopic rods 211 are fixedly connected to the outer walls of the two fixing plates 210 respectively. Limiting blocks 212 are fixedly connected to the side of the two first telescopic rods 211 away from the fixing plates 210.

[0033] Two limiting blocks 212 are fixedly connected to a first spring 213 on the side near the fixed plate 210. The end of the first spring 213 away from the limiting block 212 is fixedly connected to the outer wall of the fixed plate 210. The first telescopic rod 211 is located inside the first spring 213. A first sliding block 215 is fixedly connected to the outer wall of the two limiting blocks 212. A sliding groove 216 adapted to the first sliding block 215 is opened on the outer wall of the upper furnace 206. The inner wall of the sliding groove 216 is slidably connected to the outer wall of the first sliding block 215.

[0034] By opening the lower furnace cover 202 and the upper furnace cover 209, metal can be added to the lower furnace 201 and the upper furnace 206 respectively for heating. Simultaneously, the lower furnace pipe 204 and the upper furnace pipe 207 can connect to an external gas device to add gas into the device. When disassembling the device for cleaning, first manually move the two first sliding blocks 215 inwards, causing them to slide along the groove 216. During this sliding process, the first sliding blocks 215 will move the limiting block 212, thereby compressing the first spring 213 and the first telescopic rod 211. Then, the upper furnace 206 can be removed upwards, pulling the upper furnace pipe 207 out of the lower furnace 201. After cleaning, when reassembling, first again move the first sliding block 215 inwards, causing the limiting block 212 to move, thus compressing the first spring 213 and the first telescopic rod 211. A telescopic rod 211 is compressed, and then the slide groove 216 is aligned with the first sliding block 215, so that the upper furnace chamber 206 is successfully installed. After the upper furnace chamber 206 is installed, the first spring 213 will squeeze the limiting block 212 due to its own reaction force, so that the limiting block 212 is inserted into the interior of the upper furnace chamber 206, and the upper furnace chamber 206 is fixed. This mechanism has two furnace chambers, so it can realize independent control of dual temperature zones. The upper furnace chamber has a maximum temperature of 400°C and a normal operating temperature of 350°C, which is suitable for low temperature tempering, solution treatment and aging of aluminum alloys. The lower furnace chamber has a maximum temperature of 600°C and a normal operating temperature of 550°C, which is suitable for medium and high temperature tempering, aluminum alloy quenching, silver brazing, stainless steel annealing and other processes with slightly higher requirements. The two temperature zones can carry out different processes at the same time, or they can work together, which improves the utilization rate and flexibility of the equipment. When cleaning is required, the upper furnace chamber can be quickly disassembled and cleaned.

[0035] Figure 7The second embodiment is shown. The main difference between this embodiment and the first embodiment of the mobile detachable high-temperature pit furnace is that the moving mechanism 3 includes four rollers 301 fixedly connected to the outer wall of the base 1. Several limiting holes 302 are opened inside the rollers 301. A second sliding block 303 is slidably connected to the inner wall of the base 1. A second telescopic rod 304 is fixedly connected to the outer wall of the second sliding block 303. A locking block 306 is slidably connected to the inner wall of the base 1 to prevent the second spring 305 from pressing the second sliding block 303.

[0036] The side of the second telescopic rod 304 away from the second sliding block 303 is fixedly connected to the inner wall of the base 1. The outer wall of the second sliding block 303 is fixedly connected to the second spring 305, which is used to compress the second sliding block 303. The end of the second spring 305 away from the second sliding block 303 is fixedly connected to the inner wall of the base 1. The second telescopic rod 304 is located inside the second spring 305. The outer wall of the second sliding block 303 is fixedly connected to the limiting shaft 307 that is adapted to the limiting hole 302.

[0037] When the device needs to be fixed in one position, first move the locking block 306 upwards so that it no longer obstructs the second sliding block 303. At this time, due to the reaction force of the second spring 305, the second sliding block 303 will be squeezed, thereby moving the position of the second sliding block 303. This, in turn, moves the position of the limiting shaft 307, causing the limiting shaft 307 to insert into the position of the limiting hole 302, preventing the roller 301 from rotating, thus fixing the device. When it is necessary to move the device, first move it upwards... Move the movable locking block 306 and manually move the second sliding block 303 so that the limiting shaft 307 moves away from the limiting hole 302. When the locking block 306 is released, due to its own weight, the locking block 306 will fall downward and block the second sliding block 303, so that the limiting shaft 307 no longer fixes the roller 301, thereby moving the entire device. This mechanism can be easily moved by the user in the laboratory to adapt to different experimental layouts. At the same time, the device can be quickly fixed when it is needed to work.
