[0028] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it.

[0029] As attached Figure 1 -Attached Figure 5As shown, the utility model provides a high-temperature sealed warehouse external drive structure, including a high-temperature sealed warehouse 1 and a drive rod 2, the drive rod 2 passes through the shell 11 of the high-temperature sealed warehouse 1, and then pushes, pulls and other driving actions are performed on the materials inside the high-temperature sealed warehouse 1, and the mobile drive mechanism 4 that drives the drive rod 2 is arranged outside the high-temperature sealed warehouse 1, so that the mobile drive mechanism 4 is away from the high temperature sealed warehouse 1. The harsh environment of high temperature, turbulent airflow, and more impurities such as dust and tar reduces the performance requirements of the mobile drive mechanism 4 and improves the use stability and service life of the mobile drive mechanism 4;

[0030] The high-temperature sealed warehouse 1 includes an outer shell 11 and an insulation layer 12 arranged on the inner wall of the outer shell 11. The insulation layer 12 is used to provide insulation effect for the high-temperature sealed warehouse 1 and save energy. The outer shell 11 is provided with a mounting hole 111, and the insulation layer 12 is provided with a sliding hole 121. The mounting hole 111 and the sliding hole 121 are connected to each other. Preferably, the mounting hole 111 and the sliding hole 121 are in a straight line. In this case, the driving rod 2 is a straight rod, and the driving rod 2 can slide along the mounting hole 111 into the sliding hole 121;

[0031] The driving rod 2 is dynamically sealed on the mounting hole 111, that is, the driving rod 2 can slide and / or rotate in the mounting hole 111, and can continuously maintain the sealing of the mounting hole 111 during the sliding and / or rotation process, thereby preventing the temperature and gas in the high-temperature sealed chamber 1 from being lost, and preventing external air from entering the high-temperature sealed chamber 1. One end of the driving rod 2 is slidably arranged in the sliding hole 121 and can extend into the chamber of the high-temperature sealed chamber 1 through the sliding hole 121. The end of the driving rod 2 is adapted to the cross-sectional shape of the sliding hole 121, wherein the adaptation of the end of the driving rod 2 to the cross-sectional shape of the sliding hole 121 means that the cross-sectional shape of the end of the driving rod 2 is a proportional reduction of the cross-sectional shape of the sliding hole 121, and the two are similar to a clearance fit. For example, when the cross-section of the sliding hole 121 is circular, the cross-section of the end of the driving rod 2 is a proportionally reduced circle, that is, it can be a circular hole and cylindrical structure with clearance fit, and when the cross-section of the sliding hole 121 is rectangular, the cross-section of the end of the driving rod 2 is a proportionally reduced rectangle. At this time, the end of the driving rod 2 can block the sliding hole 121. When the driving rod 2 is needed to drive the material to move, the driving rod 2 extends from the sliding hole 121 into the high-temperature sealed bin 1 to drive the material to move. When the driving rod 2 is not needed to drive the material to move, the driving rod 2 can be retracted into the sliding hole 121, thereby filling the opening caused by the sliding hole 121 of the upper insulation layer 12, thereby ensuring the integrity of the insulation layer 12 and thus ensuring the sealing effect of the high-temperature sealed bin 1. At the same time, the driving rod 2 can also leave the space inside the bin to avoid interfering with the movement of materials in the bin.

[0032] The external driving structure of the high-temperature sealed bin provided by the utility model can make the mobile driving mechanism 4 away from the harsh environment of the high-temperature sealed bin 1 with high temperature, turbulent airflow, and a large amount of impurities such as dust and tar, reduce the performance requirements for the mobile driving mechanism 4, and improve the stability and service life of the mobile driving mechanism 4. At the same time, the matching relationship between the driving rod 2 and the thermal insulation layer 12 can make the driving rod 2 retract into the sliding hole 121 when the driving rod 2 is no longer needed to drive the material to move, thereby filling the opening caused by the sliding hole 121 of the thermal insulation layer 12, thereby ensuring the integrity of the thermal insulation layer 12 and thus ensuring the sealing effect of the high-temperature sealed bin 1, and at the same time, it can also make the driving rod 2 leave the space in the bin to avoid interfering with the movement of materials in the bin.

[0033] In one of the embodiments, a driving block 3 is provided at the end of the driving rod 2, that is, the driving block 3 is used to drive the material to move. In this embodiment, the driving block 3 is used as the end of the driving rod 2. At the same time, since the driving block 3 is a structure that contacts the material, it can be made of high-temperature resistant and wear-resistant material to increase the service life, while the requirements of the driving rod 2 can be reduced, thereby reducing costs. Preferably, the driving block 3 is detachably arranged at the end of the driving rod 2 through a fastener, thereby facilitating the replacement of the driving block 3. In addition, the driving block 3 is adapted to the cross-sectional shape of the sliding hole 121, that is, the driving block 3 can slide along the sliding hole 121 and then extend into the bin, and can also stay in the sliding hole 121 to ensure the sealing effect of the insulation layer 12.

[0034] In one embodiment, the driving block 3 is a graphite block, so that the driving block 3 has the characteristics of high temperature resistance and wear resistance, thereby improving the use stability and service life of the driving block 3.

[0035] In one embodiment, the other end of the driving rod 2 is connected to a moving driving mechanism 4 for driving the driving rod 2 to move.

[0036] In one embodiment, the mobile driving mechanism 4 is used to drive the driving rod 2 to move back and forth, so that the driving rod 2 can push the material to move. In this embodiment, the mobile driving mechanism 4 can be a linear driving mechanism such as a linear module, a cylinder or a hydraulic cylinder. Preferably, a linear module is used, which has a strong load capacity and the output slide 41 moves stably and reliably. Preferably, a vertical mounting plate 42 is provided on the slide 41 of the linear module, and the vertical mounting plate 42 is used to install the driving rod 2 so that the driving rod 2 is arranged parallel to the main body of the linear module.

[0037] Preferably, two driving rods 2 are arranged in parallel, and the mobile driving mechanism 4 is used to drive the two driving rods 2 to move back and forth, thereby improving the bearing capacity of the driving rods 2 and increasing the service life.

[0038] In another embodiment, the mobile driving mechanism 4 is used to drive the driving rod 2 to reciprocate and rotate. In this embodiment, the mobile driving mechanism 4 includes a linear driving mechanism and a rotary driving mechanism, and the driving rod 2 is rotationally arranged on the output end of the linear driving mechanism, and the rotary driving mechanism is used to drive the driving rod 2 to rotate. In this embodiment, the driving rod 2 can drive the driving block 3 to rotate, so that the driving block 3 can rotate after extending into the high-temperature sealed bin 1, thereby hooking the material or engaging with the material, thereby achieving pushing or pulling the material to move, thereby increasing the driving mode of the material.

[0039] In one embodiment, the external drive structure of the high temperature sealed chamber further includes a dynamic sealing mechanism 5, which is used to realize the dynamic sealing of the drive rod 2 and the mounting hole 111; the dynamic sealing mechanism 5 includes a flange, a sleeve 52 and a sleeve sealing ring 53, the flange is provided with a hole through which the drive rod 2 passes, the flange is provided on the mounting hole 111, and can be a permanent fixed setting or a detachable connection setting, the sleeve 52 is provided on the side of the flange away from the high temperature sealed chamber 1, the drive rod 2 slides on the sleeve 52, thereby providing guidance for the movement of the drive rod 2, and the sleeve sealing ring 53 is provided between the sleeve 52 and the drive rod 2, providing sealing between the drive rod 2 and the sleeve 52. In this embodiment, one end of the drive rod 2 is supported by the mobile drive mechanism 4, and the middle part is supported by the sleeve 52, so that the drive rod 2 can be a double-point support mechanism instead of a cantilever structure, thereby improving the movement stability of the drive rod 2.

[0040] In one embodiment, the flange includes a fixed flange 51 fixed on the mounting hole 111 and a connecting flange 54 set on the fixed flange 51 by fasteners, wherein the fixed flange 51 is permanently fixed on the housing 11, and can be integrally formed or fixed by welding, and the connecting flange 54 is used to fix the sleeve 52, and is detachably connected to the fixed flange 51 by fasteners. Such a configuration greatly facilitates the installation of the drive rod 2 and the sleeve 52 on the flange and simplifies the installation difficulty. A sealing ring 55 is also provided between the fixed flange 51 and the connecting flange 54 to ensure the sealing effect between the fixed flange 51 and the connecting flange 54.
