Description

Technical Field

[0001] This application relates to the field of materials, and particularly to a highly efficient heat-insulating ceramic fiber heat-insulating board. Background Art

[0002] In modern industry, in many occasions that require heating, heat-insulating materials are often needed to insulate equipment such as furnace bodies and kettle bodies. The ceramic fiber heat-insulating board is one of the heat-insulating boards with better heat-insulating effects. The ceramic fiber board is the aluminosilicate fiber board, a board made of refractory materials. It maintains good mechanical strength even after heating. This product is a rigid and fiber heat-insulating product with supporting strength compared to fiber blankets and felts. The main raw materials are flint clay and alumina powder. The ceramic fiber heat-insulating board has good mechanical processing performance and can well meet the usage needs when used as a general heat-insulating board body. However, in some special cases, such as when pipes need to be installed, drilling operations are required, and the matching degree between the drilling and the pipes is insufficient, resulting in unstable use. Although the ceramic fiber board has strong mechanical properties, it may still be damaged after long-term use. For the heat-insulating board with a pipe part installed, since its structure is more complex than that of an ordinary heat-insulating board, how to ensure the sealed heat insulation during installation and how to monitor whether the performance of the position of the pipe part installed on the heat-insulating board is damaged after long-term use are technical problems that need to be solved. Summary of the Invention

[0003] Object of the Invention: This application aims to overcome the defects of the prior art and provide a highly efficient heat-insulating ceramic fiber heat-insulating board.

[0004] Technical Solution: A highly efficient heat-insulating ceramic fiber heat-insulating board includes a first heat-insulating board, a second heat-insulating board, a pipe part, a pipe part fixing device, and a fixing frame. An installation groove is provided at the first heat-insulating board. The pipe part fixing device is installed in the installation groove. The second heat-insulating board can close the installation groove.

The fixing frame is fixed to the second heat-insulating board through an adhesive, and the fixing frame is fixed to the first heat-insulating board through an adhesive.

[0005] Thus, the fixing frame realizes the fixed connection between the first heat-insulating board and the second heat-insulating board, and the second heat-insulating board realizes the sealing of the open end of the installation groove.

[0006] Furthermore, the pipe fixing device includes two mutually spliced installation units. Each installation unit includes a heat insulation plate body and two mounting brackets. The heat insulation plate body is installed between the two mounting brackets. The heat insulation plate body includes a first plate body, a second plate body, and a third plate body located between the first plate body and the second plate body. The first plate body and the second plate body are parallel, the third plate body is perpendicular to the first plate body, and one end of the first, second, and third plate bodies close to the pipe has a first arc-shaped groove; the mounting bracket includes a first groove box cooperating with the first plate body, a second groove box cooperating with the second plate body, and a third groove box cooperating with the third plate body. The third groove box is connected between the first groove box and the second groove box. Both ends of the first groove box have first connecting side plates, and both ends of the second groove box have second connecting side plates. The two first connecting side plates of the first groove box of one mounting bracket of each installation unit are fixedly connected to the two first connecting side plates of the first groove box of the other mounting bracket, and the two second connecting side plates of the second groove box of one mounting bracket of each installation unit are fixedly connected to the two second connecting side plates of the second groove box of the other mounting bracket; at the first groove box, second groove box, and third groove box of the mounting bracket close to the pipe in the installation unit, there are second arc-shaped grooves that cooperate with the first arc-shaped groove and are used for installing the pipe.

[0007] Furthermore, the pipe fixing device is used to fix a pipe.

[0009] Furthermore, the two corresponding first connecting side plates are fixedly connected by bolts and nuts, and the two corresponding second connecting side plates are fixedly connected by bolts and nuts; alternatively, the two corresponding first connecting side plates are fixedly connected by welding, and the two corresponding second connecting side plates are fixedly connected by welding.

[0010] Further, one end of the installation groove is closed and the other end is open. The second heat insulation plate can close the open end, and the first through hole is located at the closed end of the installation groove. On the side of the first groove box facing the first through hole, a first abutting bracket with a T-shaped cross section is fixed. The first abutting bracket abuts against the closed end of the installation groove. On the side of the second groove box facing the second through hole, a second abutting bracket with a T-shaped cross section is fixed.

Sealant is coated on the contact surface between the first groove box, the second groove box and the third groove box of each mounting rack and the installation groove. There is sealant between the pipe part and the first through hole, and there is sealant between the pipe part and the second through hole. The pipe part fixing device divides the space in the installation groove into an inner space, an outer space and a middle space. The inner space is located between the closed end of the installation groove and the first plate body. The outer space is located between the second plate body and the second heat insulation plate. The middle space is located between the first plate body and the second plate body. The two third plate bodies of the pipe part fixing device divide the middle space into a first middle space and a second middle space. The inner space, the first middle space, the second middle space and the outer space are all independent spaces with airtightness.

[0012] Further, a detection unit is further included. The detection unit includes a detection main pipe, a mounting box, a first detection pipe, a second detection pipe, a third detection pipe and a fourth detection pipe. A multi-way valve is installed in the mounting box. The detection main pipe, the first detection pipe, the second detection pipe, the third detection pipe and the fourth detection pipe are all connected to the multi-way valve. The multi-way valve can make the detection main pipe communicate with any one of the first detection pipe, the second detection pipe, the third detection pipe and the fourth detection pipe separately. The end of the first detection pipe is located in the inner space and can inject gas into the inner space.

Sealant is provided in all the first strip-shaped accommodation grooves, all the second strip-shaped accommodation grooves, and all the third strip-shaped accommodation grooves.

[0014] Thus, good installation of the first, second, and third detection pipes is achieved without affecting the sealing performance of each independent space.

[0015] Furthermore, the main detection pipe, the first detection pipe, the second detection pipe, the third detection pipe, and the fourth detection pipe all have strip-shaped grooves. Temperature sensors and wires connected to the temperature sensors are installed at the strip-shaped grooves of the first detection pipe, the second detection pipe, the third detection pipe, and the fourth detection pipe. A data transmission line is installed in the strip-shaped groove of the main detection pipe. A data processing unit is installed in the installation box. The data transmission line and all the wires are electrically connected to the data processing unit. The data processing unit can collect data from all the temperature sensors and transmit it through the data transmission line; the second heat insulation board has a main pipe perforation through which the main detection pipe passes, and there is sealant between the main detection pipe and the main pipe perforation.

[0016] Furthermore, both the first perforation and the second perforation are cylindrical.

[0017] Furthermore, the pipe part fixing device is used to fix the pipe part. The pipe part includes a first pipe body passing through the first perforation, a second pipe body passing through the second perforation, and a third pipe body located between the first pipe body and the second pipe body. The first pipe body and the second pipe body are parallel, the third pipe body is perpendicular to the first pipe body, there is a connecting elbow between the first pipe body and the third pipe body, and there is a connecting elbow between the second pipe body and the third pipe body.

[0018] Furthermore, the first pipe body, the second pipe body, and the third pipe body are all cylindrical pipes.

[0019] Furthermore, the mounting bracket is made of stainless steel material.

[0020] Beneficial effects: The heat insulation board of the present application uses ceramic fiber material as the main body and has good heat insulation effect itself.

[0021] When installing the pipe part, the mounting bracket is used to reinforce and fix between the heat insulation board body and the pipe part, so as not to damage the mechanical properties of a single heat insulation board body and it will not be damaged after long-term use.

[0022] The pipe part adopts a bent structure, so as to form an installation space in the installation groove, thereby ensuring the sealing performance of the installation between the pipe part and the heat insulation fiber board. Although the pipe part is installed, it does not affect the overall heat insulation effect.

[0023] The temperature and sealing performance inside the installation groove (the sealing performance mainly detects whether there is damage to the plate body) can be regularly detected, so as to ensure the stability of the performance of the entire heat insulation board.

[0037] As shown in the figure, for the heat insulation plate of the present application, by installing a pipe fixing device in the installation groove and fixing the pipe part in the pipe fixing device in a bent manner, it not only does not hinder the transmission of the medium, but also makes the pipe part have good heat insulation and sealing performance and installation strength when installed in the heat insulation plate, ensuring the heat insulation performance of the entire heat insulation plate. And the groove cooperates with the installation rack of the stainless steel pipe, so that the pipe fixing unit has better mechanical strength and makes the installation of the pipe part more stable. Although the stainless steel material in the present application has strong heat conductivity, it only plays a role in fixing and strengthening. The medium is conveyed into the kettle body, the furnace body or other equipment by the pipe part. The stainless steel pipe only contacts the pipe body and does not contact the heat source. Therefore, overall, it will not cause the heat insulation effect of the heat insulation plate to deteriorate.

[0038] In addition, during installation, whether installing the heat insulation panel body between two mounting brackets, splicing two mounting units, or fixedly installing the pipe part fixing device in the mounting groove, the method of first coating with sealant and then installing is adopted. In this way, on the one hand, the sealant can further stabilize the mutually contacting components, and on the other hand, it has a sealing effect, dividing the space in the mounting groove into independent airtight spaces, further increasing the heat insulation effect, avoiding the heat circulation caused by air flow, and the detection unit can independently inject gas into each space. The detection main pipe can detect the airtightness of each space by connecting the gas injection device and the air pressure detection device, so as to detect whether the heat insulation panel body in the mounting groove is damaged, whether the first heat insulation panel and the second heat insulation panel are damaged, and conduct monitoring. Moreover, for each independent space, the temperature can also be detected by a temperature sensor, so as to judge whether the heat insulation effect is normal from the perspective of temperature. Under normal circumstances, the temperature difference between each space should be within a certain range, so as to judge whether the entire heat insulation panel is intact from the two perspectives of airtightness and temperature, ensuring a good heat insulation effect. And the detection unit of the present application integrates the gas injection pipe, the wire, and the temperature sensor together, and the detection unit is installed at the splicing position of the two mounting units, so as to minimize the damage to the structure of the panel body and ensure the mechanical performance and heat insulation effect of the panel body.
