[0028] In order to facilitate understanding of the technical solution of the present application, the problems existing in the existing degassing process applied to quartz tubes are explained here:

[0029] In the existing scheme, the main reason is that there is a gap between the muffle furnace and the quartz tube, which causes a lot of heat loss in the quartz tube, affecting the degassing effect. At present, in order to avoid a lot of heat loss, tin foil is usually used to wrap the quartz tube, but this method needs to be re-wrapped every time it is used, which is time-consuming and labor-intensive, resulting in low processing efficiency; and the number of times the tin foil can be used is also greatly limited. After a certain amount of use, new tin foil needs to be used, resulting in high degassing costs; in addition, the wrapping method is unstable, resulting in unstable insulation effect, which in turn leads to a lot of heat loss, affecting the degassing effect.

[0030] Based on this, on the one hand, the present application provides a heat preservation device, which is arranged between the muffle furnace and the quartz tube, and can fill the gap between the two to insulate the quartz tube.

[0031] like Figure 1 and Figure 2 As shown, the heat preservation device includes a plurality of mounting blocks 110, a plurality of connecting members 120 and a plurality of heat preservation structures (not shown). The mounting blocks 110 are hollow, and a heat preservation structure is provided inside each mounting block 110. A connecting member 120 is also provided on each mounting block 110, so that the plurality of mounting blocks 110 can be connected or separated from each other, and the plurality of mounting blocks 110 are connected to each other to enclose a hollow structure having a through opening 130, and the plurality of mounting blocks 110 are arranged around the through opening 130.

[0032] It should be noted that, in this embodiment, the heat-insulating structure is quartz wool. In other embodiments, the heat-insulating structure may be other high-temperature resistant heat-insulating materials, such as aluminum silicate, glass wool, etc.

[0033] Thus, when degassing the quartz tube, the quartz tube can be placed in the through-hole 130, and a plurality of mounting blocks 110 are arranged between the quartz tube and the inner wall of the muffle furnace, thereby filling the gap between the two. At the same time, since each mounting block 110 is provided with a heat preservation structure inside, and a plurality of mounting blocks 110 are arranged around the through-hole 130, the plurality of mounting blocks 110 are arranged around the quartz tube, which can insulate the quartz tube and avoid excessive heat loss of the quartz tube, thereby ensuring a better degassing effect.

[0034] In addition, the mounting blocks 110 are connected by connectors 120, which facilitates the assembly of the mounting blocks 110, making the speed of assembling the mounting blocks 110 to form a hollow structure faster and improving processing efficiency; at the same time, compared with tin foil, the service life of the insulation device is longer, so it can effectively reduce the degassing cost.

[0035] In one embodiment, the outer side of the mounting block 110 has a matching groove 111 , and when a plurality of mounting blocks 110 are connected to each other, the plurality of matching grooves 111 surround and form the above-mentioned through hole.

[0036] Understandably, see Figure 3 In this embodiment, the heat preservation device is used to keep the quartz tube warm. The shape of the through-hole 130 matches the external shape of the quartz tube, so the cross-sectional shape of the through-hole 130 is circular, and the corresponding matching groove 111 is an arc groove. Of course, when the heat preservation device is used to keep other shaped products warm, the through-hole 130 needs to be set to a corresponding shape, and the corresponding matching groove 111 also needs to be set to correspond to the surface shape of the product, which is not limited here.

[0037] Furthermore, the heat preservation device includes two mounting blocks 110, and the matching grooves 111 on the two mounting blocks 110 enclose a circular through-hole 130, so the matching grooves 111 are semicircular grooves. In this way, compared with a larger number of mounting blocks 110, the two mounting blocks 110 can be further conveniently assembled, thereby improving the overall efficiency.

[0038] In one embodiment, the heat preservation device further includes a plurality of protective pads 140. The groove wall of each matching groove 111 is paved with a protective pad 140, so that the protective pad 140 contacts the quartz tube to avoid damage to the quartz tube, and can also fit the quartz tube more closely to improve the heat preservation effect.

[0039] It is understandable that when the protective pad 140 is used for heat preservation of the quartz tube, the material of the protective pad 140 is also a high temperature resistant material, such as a high temperature resistant rubber pad. In addition, the protective pad 140 can also be made of other high temperature resistant flexible heat preservation materials to further improve the heat preservation effect.

[0040] In one embodiment, the hollow structure is a rectangular structure, so that the hollow structure can fit more closely with the inner wall of the muffle furnace, further improving the thermal insulation effect.

[0041] It is understandable that when there are two mounting blocks 110, each mounting block 110 is a rectangular structure with a matching groove 111 on one side, and the two mounting blocks 110 with the matching grooves 111 are connected to each other to form the above-mentioned hollow structure. At the same time, since the two mounting blocks 110 are arranged around the through opening 130, the through opening 130 is located in the middle of the hollow structure.

[0042] Furthermore, the outer surface of the hollow structure may also be paved with the above-mentioned protective pad 140, which can not only avoid wear between the hollow structure and the inner wall of the muffle furnace, but also make the hollow structure and the inner wall of the muffle furnace fit more closely, thereby improving the thermal insulation effect.

[0043] Please also see Figure 4 In one embodiment, the mounting block 110 is provided with a matching protrusion 112, and the matching protrusion 112 and the mounting block 110 are together enclosed to form a through opening 130. In this way, after a plurality of mounting blocks 110 are enclosed to form a hollow structure, the matching protrusion 112 can form a protruding structure on one side of the hollow structure, and the protruding structure is arranged around the through opening 130 and is arranged adjacent to the through opening 130.

[0044] It should be noted that during the application of the insulation device, the insulation device is located at the furnace mouth of the muffle furnace, the protrusion structure is a circular protrusion, and the protrusion structure can be inserted into the gap between the furnace mouth and the quartz tube, further filling the gap between the muffle furnace and the quartz tube, thereby improving the insulation effect.

[0045] In one embodiment, the mounting block 110 has two connection ends, and each connection end is provided with a connection member 120, so that the connection ends of multiple mounting blocks 110 are sequentially connected and enclosed to form the above-mentioned hollow structure.

[0046] In combination with the above embodiment, it can be determined that when there are two mounting blocks 110, the two connection ends on the mounting block 110 are located on the side of the mounting block 110 having the matching groove 111, and the matching groove 111 is located between the two connection ends. When there are more mounting blocks 110, multiple mounting blocks 110 can be connected in sequence through the connecting pieces 120 at the two connection ends, so as to enclose and form the above hollow structure.

[0047] In one embodiment, the connector 120 is a magnetic member to further facilitate the connection between the mounting blocks 110. Of course, the connector 120 can also be a quick-insert structure, and the connectors 120 on the two interconnected connection ends can be connected to each other.

[0048] Specifically, the magnetic attraction member is a high temperature resistant magnet.

[0049] In one embodiment, the mounting block 110 includes a body 113 and a cover 114. The body 113 is provided with an open cavity 1131 for accommodating the heat preservation structure, and the cover 114 is detachably connected to the body 113 for opening or closing the open cavity 1131, thereby improving the heat preservation effect after the open cavity 1131 is closed.

[0050] Furthermore, the body 113 is provided with a slide groove 1132, and the cover 114 is slidably disposed in the slide groove 1132. Furthermore, the inner walls of the opening 1131 opposite to each other are provided with slide grooves 1132, and the two ends of the cover 114 are respectively slidably disposed in the two slide grooves 1132, so that the slide of the cover 114 is smoother.

[0051] It is understandable that the same end of the two slide grooves 1132 passes through the mounting block 110 , thereby facilitating the cover body 114 to be inserted into the slide groove 1132 , and the other ends of the two slide grooves 1132 can limit the sliding of the cover body 114 .

[0052] It should be noted that, in order to improve the sealing between the main body 113 and the cover body 114 , thereby improving the heat preservation effect of the heat preservation device, a high temperature resistant sealing gasket may be provided in the slide groove 1132 and / or on the cover body 114 .

[0053] In one embodiment, the mounting block 110 is made of polytetrafluoroethylene or other high temperature resistant materials.

[0054] On the other hand, the present application also provides a degassing device, which includes the above-mentioned heat preservation device.

[0055] Furthermore, the degassing equipment also includes a heating device, which can heat the product. The hollow structure in the heat preservation device is sleeved on the outside of the product to fill the gap between the heating device and the product, thereby improving the heat preservation effect.

[0056] Specifically in this embodiment, the heating device is a muffle furnace and the product is a quartz tube.

[0057] 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.

[0058] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
