DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] like Figure 1-4As shown, the utility model provides a technical solution: a sealed chamber with multi-stage heat insulation and automatic damage repair, comprising a resistance furnace body 1, the resistance furnace body 1 comprises a base 2, a furnace body assembly 3 is arranged on the top of the base 2, and an explosion-proof assembly 4 is arranged on the top of the furnace body assembly 3; the explosion-proof assembly 4 comprises a high-temperature gas box 41, both sides of the high-temperature gas box 41 are fixedly connected with hollow telescopic rods 42, the other ends of the two hollow telescopic rods 42 are rotatably connected with explosion-proof plates 43, the centers of the two explosion-proof plates 43 are rotatably connected with connecting seats 44, the sides of the two connecting seats 44 close to each other are provided with sliders 46, and the bottom of the explosion-proof plates 43 is provided with limited position blocks 45, the furnace body assembly 3 comprises a furnace box 31, the inner wall of the furnace box 31 is provided with platinum thermal resistance wires 34, the platinum thermal resistance wires 34 are distributed in an annular shape, an explosion-proof cover 35 is arranged on the top of the furnace box 31, the explosion-proof cover 35 is fixedly connected with the high-temperature gas box 41, and a rotating seat 36 is arranged on one side of the explosion-proof cover 35, The bottom of the base 2 is provided with a lifting plate 37, and the bottom of the base 2 is provided with a supporting leg 21, which is distributed in an arc shape. The base 2 is provided with a clamping groove 22 at the bottom of the explosion-proof plate 43, and the clamping groove 22 is clamped with the limiting clamping block 45 to limit the furnace box 31 and the explosion-proof cover 35 under the action of the explosion-proof component 4, so as to achieve an explosion-proof effect. When the temperature in the furnace box 31 rises, its heat will enter the high-temperature gas box 41 through the explosion-proof cover 35, and under the action of thermal expansion and contraction, the hollow telescopic rods 42 on both sides are driven to stretch to both sides. At this time, the explosion-proof plate 43 is driven to tilt under the action of the connecting seat 44 as a fulcrum, so that the slider 46 and the slide groove 32 are clamped with each other, and the furnace box 31 and the explosion-proof cover 35 are limited, thereby avoiding the furnace box 31 and the explosion-proof cover 35 from being separated during the use of the furnace body assembly 3, and solving the technical problem that the furnace box 31 and the explosion-proof cover 35 are easily separated during use.
[0023] Further, such as Figure 2 - Figure 3 As shown: a heat insulation layer 33 is embedded and installed on the outer side of the platinum thermal resistance wire 34 on the furnace box 31. There are two heat insulation layers 33 in total, and the diameters of the two heat insulation layers 33 increase from the inside to the outside. By setting two heat insulation layers 33, the heat of the inner wall of the furnace box 31 is blocked to prevent the excessive heat inside the furnace box 31 from being transferred to the outside, so that the experimenter is not injured when touching the furnace box 31, thereby solving the technical problem of poor heat insulation effect of the existing furnace body.
[0024] The above solution still has the problem that when the explosion-proof cover 35 is lifted by the hydraulic push rod 23 and the auxiliary push rod 24, the explosion-proof assembly 4 cannot be separated from the furnace box 31. Figure 3 As shown: In this solution, a slide groove 32 is provided on one side of the furnace box 31 located on the slider 46, and the slide groove 32 is slidably connected to the slider 46. Under the action of the slide groove 32, the slider 46 is slidably connected to the slide groove 32, so that the explosion-proof plate 43 and the furnace box 31 are a detachable structure.
[0025] The above scheme still has the problem that the explosion-proof cover 35 is heavy and inconvenient to take due to the particularity of the explosion-proof structure. Figure 2 As shown: In the present embodiment, a hydraulic push rod 23 is arranged on the base 2 at one side of the furnace box 31, and the hydraulic push rod 23 is rotatably connected to the rotating seat 36. An auxiliary push rod 24 is arranged on the base 2 at the other side of the furnace box 31, and the top of the auxiliary push rod 24 is in contact with the lifting plate 37. The explosion-proof cover 35 is driven to move upward by the hydraulic push rod 23 and the auxiliary push rod 24 until the slider 46 slides out of the slide groove 32. At this time, the explosion-proof cover 35 can be rotated to one side, so that the outer opening on the furnace box 31 is not blocked, so as to facilitate the feeding and taking operations.
[0026] Working principle: Figure 1-4 As shown, first, the resistance furnace body 1 is erected at a specified position by the support legs 21, and then the hydraulic push rod 23 and the auxiliary push rod 24 are turned on to drive the explosion-proof cover 35 to move upward until the slider 46 slides out of the slide groove 32. At this time, the explosion-proof cover 35 can be rotated to one side, and after the material is placed in the furnace box 31, the explosion-proof cover 35 is rotated and reset to align the slider 46 with the slide groove 32, and the hydraulic push rod 23 and the auxiliary push rod 24 are controlled to drive the explosion-proof cover 35 to move downward so that the furnace box 31 and the explosion-proof cover 35 are closed, and then the platinum thermal resistance wire 34 is turned on to heat the material. During the heating process, after the temperature in the furnace box 31 increases, its heat will enter the high-temperature gas box 41 through the explosion-proof cover 35, and under the action of thermal expansion and contraction, the hollow telescopic rods 42 on both sides are driven to stretch to both sides. At this time, the explosion-proof plate 43 is driven to tilt with the connection seat 44 as a fulcrum, so that the slider 46 and the slide groove 32 are mutually engaged, so as to limit the furnace box 31 and the explosion-proof cover 35.
[0027] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
