Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0024] Please refer to Figures 1-3 The utility model provides a technical scheme:

[0025] A chemical smelting furnace with safety protection structure, comprising:

[0026] The smelting furnace body 1 is connected with the protective cover 2 through the adjusting mechanism, the adjusting mechanism comprises a first servo electric cylinder 8, a first connecting block 9, an adjusting rod 10 and a support frame 11, one end of the adjusting rod 10 is fixedly connected with the protective cover 2, and the other end of the adjusting rod 10 is provided with a connecting groove 12, the support frame 11 is rotatably connected with the adjusting rod 10, and the support frame 11 is fixedly installed on the smelting furnace body 1, the first servo electric cylinder 8 is installed on the support frame 11, and the output end of the first servo electric cylinder 8 is connected with the first connecting block 9, and the first connecting block 9 is rotatably connected in the connecting groove 12;

[0027] Further, the protective cover 2 is provided with two sealing rings 13, the smelting furnace body 1 is provided with two sealing grooves 14, and the sealing grooves 14 are provided with sealing washers 15, the sealing rings 13 are in contact with the sealing washers 15, the protective cover 2 is a double-layer heat insulation structure, the double-layer heat insulation structure is an inner layer of high-temperature-resistant alloy 16 and an outer layer of heat insulation ceramic fiber 17, the observation window 3 is high-temperature-resistant quartz glass, the protective cover 2 is provided with the observation window 3, the outlet of the smelting furnace body 1 is provided with a high-temperature-resistant baffle 4, the high-temperature-resistant baffle 4 is made of nickel-chromium alloy, and the high-temperature-resistant baffle 4 is provided with a groove 18;

[0028] In the feeding stage, the operator issues an instruction through the controller 26, the controller 26 transmits a signal to the first servo cylinder 8, the first servo cylinder 8 is started, and the output end of the first servo cylinder 8 drives the first connecting block 9 to move. Through the rotary connection between the first connecting block 9 and the connecting groove 12 of the adjusting rod 10, and the rotary connection between the adjusting rod 10 and the support frame 11, the adjusting rod 10 rotates around the support frame 11, and then drives the protective cover 2 to open. This process relies on the working principle of the adjusting mechanism, and takes the first servo cylinder 8 as the power source. The linear motion is converted into the rotary motion of the adjusting rod 10 through the rotary connection, the accurate opening and closing of the protective cover 2 is realized, the opening angle and speed can be accurately controlled through the controller 26, the motor speed of the first servo cylinder 8 is adjusted by outputting electrical signals with different frequencies / occupancy ratios, and the opening speed adjustment of the protective cover 2 is realized; a closed loop is formed by matching the speed sensor, the actual speed is compared with the preset value in real time, the electrical signal is corrected to ensure the accuracy. Based on the mechanical design, the output displacement of the first servo cylinder 8 and the rotation angle of the adjusting rod 10 (indirectly corresponding to the opening angle of the protective cover 2) are associated, and the actual angle is fed back through the angle sensor. The closed loop calibrates the action of the cylinder to ensure that the angle is consistent with the preset value, and meets different feeding requirements. The opening angle of the protective cover 2 is preset, the controller 26 is provided with multiple gears for selection, or a program is written according to the production process to realize automatic calling of different angles in different stages, and the opening angle is set according to the feeding requirement, equipment safety (the adjusting mechanism bears the maximum angle), and operation convenience (observation and feeding are within the appropriate range). After the protective cover 2 is opened to the appropriate angle and the chemical raw materials are added, the first servo cylinder 8 is controlled to operate in reverse to close the protective cover 2. At this time, the sealing ring 13 on the protective cover 2 contacts the sealing gasket 15 in the sealing groove 14 of the smelting furnace body 1 to realize sealing, and utilizes elastic deformation to prevent heat and harmful gas leakage; the double-layer heat insulation structure (the inner layer is a high-temperature resistant alloy 16, and the outer layer is a heat insulation ceramic fiber 17) of the protective cover 2 can effectively block high temperature to avoid scalding of the operator, and the high-temperature resistant quartz glass observation window 3 thereon facilitates the operator to observe the situation in the furnace in real time without opening the protective cover 2, which reduces the safety hazard, saves energy, and is conducive to environmental protection.

[0029] The base is provided with a turnover mechanism for controlling the turnover of the smelting furnace body 1. The turnover mechanism comprises two second connecting blocks 19, two third connecting blocks 20, a rotating block 21, two second servo cylinders 22 and two supporting rods 23. The two second connecting blocks 19 and the two third connecting blocks 20 are fixedly connected with the smelting furnace body 1. One end of each of the two supporting rods 23 is rotatably connected with one of the two second connecting blocks 19, and the two supporting rods 23 are fixedly connected with the supporting plate 6. One end of each of the two second servo cylinders 22 is rotatably connected with the supporting plate 6, and the output end of each of the second servo cylinders 22 is connected with the rotating block 21. The rotating block 21 is rotatably connected with one of the two third connecting blocks 20.

[0030] In the discharging stage, the operator starts the second servo cylinder 22 through the controller 26, and the output end drives the rotating block 21 to move. Combined with the rotating connection between the rotating block 21 and the third connecting block 20, and the rotating connection between the supporting rod 23 and the second connecting block 19 and the fixed connection between the supporting rod 23 and the supporting plate 6, the smelting furnace body 1 will overturn around the connecting point of the supporting rod 23 and the second connecting block 19 under the pushing of the second servo cylinder 22. This is because in the overturning mechanism, the second servo cylinder 22 provides power, and through the rotating connection of each component, a linkage mechanism is formed to convert linear motion into overturning motion of the furnace body. The controller 26 can accurately adjust the overturning angle and speed of the furnace body by controlling the extension and retraction amount of the servo cylinder, ensuring that the solution flows out smoothly. As the furnace body overturns, the solution flows out of the outlet, and the nickel-chromium alloy high-temperature baffle 4 at the outlet can block the splashing of the solution, and the groove 18 can play a guiding role to reduce the safety risk of discharging. After the solution is poured, the second servo cylinder 22 is operated in reverse to reset the furnace body. During the whole process, the adjusting mechanism and the overturning mechanism are controlled by the controller 26 to realize automatic operation, replacing the traditional manual operation, which not only reduces the labor intensity of the operator, but also improves the operation accuracy and efficiency, and reduces the influence of human error.

[0031] The base includes a bottom plate 5, a supporting plate 6 and a buffer assembly. The buffer assembly is arranged between the bottom plate 5 and the supporting plate 6, and includes a plurality of dampers 24 and a plurality of air springs 25. The two ends of the dampers 24 and the air springs 25 are respectively connected with the bottom plate 5 and the supporting plate 6. The mounting threaded holes 7 are formed in the bottom plate 5.

[0032] In the smelting stage, the operator can observe the smelting of the raw materials in the furnace through the observation window 3 in real time. At the same time, the dampers 24 and the air springs 25 in the buffer assembly continue to play a role: the dampers 24 consume vibration energy through internal damping force to reduce transmission, and the air springs 25 use air elasticity to buffer vibration, and can adapt to different loads and vibration intensities by adjusting air pressure. The combination of the two effectively reduces the vibration amplitude of the equipment during operation, protects the components from damage, reduces the problem of component loosening and damage caused by vibration, and ensures the stable and safe operation of the equipment.

[0033] In the above embodiment, the controller 26 is installed on the supporting plate 6, and the controller 26 is electrically connected with the first servo cylinder 8 and the second servo cylinder 22 respectively.

[0034] It should be noted that the specific model and specification of the controller 26, the first servo cylinder 8 and the second servo cylinder 22 need to be determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in the art, and therefore will not be described in detail.

[0035] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
