Description

Technical Field

[0001] The utility model relates to the technical field of composite magnesium silicate tube shells, and specifically relates to a composite magnesium silicate tube shell. Background Art

[0002] Composite magnesium aluminum silicate thermal insulation materials are made of inorganic materials such as palygorskite, sepiolite, bentonite, and ceramic fiber as the main raw materials. Composite magnesium aluminum silicate thermal insulation materials are non-combustible materials with good safety. They are the best choice for thermal insulation in environments with high fire protection requirements, such as oil storage depots, chemical plants, civil buildings, and gas storage depots. Special raw materials are added to the high-temperature formula of composite magnesium aluminum silicate, and its high-temperature thermal insulation performance is often better than that of low-temperature products. Therefore, it can achieve better thermal insulation effects when used in high-temperature equipment and pipelines. With the continuous development of science and technology, composite magnesium aluminum silicate has begun to be used in the production of pipe shells.

[0003] According to the announcement number: CN216743449U, the patent name is: an aluminum silicate tube shell with an anti-corrosion structure. The patent has an aluminum silicate tube shell with an anti-corrosion structure. By designing the inner diameter of the outer support shell and the outer diameter of the second aluminum silicate tube shell component to be consistent, the connecting end of the second aluminum silicate tube shell component can be just placed inside the outer support shell, thereby strengthening the connection tightness between the two and avoiding loosening of the connection after a long time. However, although the patent has good connection tightness, when it is installed, it needs to be wrapped around the outside of the pipe in layers according to the thickness of the insulation and tied with wire layer by layer, which is more troublesome to install. Utility Model Content

[0004] The utility model provides a composite magnesium silicate pipe shell, which solves the problem in the related art that during installation, the pipe shell needs to be wrapped around the pipe in layers according to different insulation thicknesses and tied up with wires layer by layer, which makes the installation more troublesome.

[0005] The technical solution of the utility model is as follows: a composite magnesium silicate tube shell, comprising a tube shell body, the outer surface of the tube shell body is provided with a fixing mechanism, the fixing mechanism comprises two fixing shells sleeved on the outer surface of the tube shell body, the two side surfaces of each fixing shell are fixedly connected with bearings, the inner ring of each bearing is fixedly connected with a threaded rod, the outer surface of each threaded rod is threadedly connected with a spiral ring, the outer surface of each spiral ring is fixedly connected with a fixing ring, and the inner wall of the fixing ring is in contact with the outer surface of the tube shell body.

[0006] Furthermore, both ends of the two fixed shells close to each other are fixedly connected with fixing plates, and every two fixing plates are fixedly connected by bolts. The staff can fix the two fixing plates together by bolts, thereby realizing the connection and fixation between the two fixed shells. When the fixing mechanism needs to be disassembled later, the staff can use a wrench to disassemble the fixing mechanism, which is convenient and quick, and facilitates disassembly and installation during later maintenance.

[0007] Furthermore, each of the threaded rods is fixedly connected to a turning handle at one end away from the fixed shell, and an anti-slip sleeve is provided on the outer surface of each turning handle. The staff can rotate the turning handle to drive the threaded rod to rotate, thereby avoiding the staff from directly holding the threaded rod to rotate, thereby improving overall practicality. At the same time, the anti-slip sleeve can increase the friction between the hand and the turning handle when the staff holds the turning handle, effectively avoiding hand slippage. At the same time, the anti-slip sleeve has a certain flexibility, which can effectively increase the comfort of the staff when holding the turning handle.

[0008] Furthermore, two sliding rods are fixedly connected to the two side surfaces of each of the fixed shells, and two sliding rings are fixedly inlaid on the outer surface of each fixed ring. The ends of the two sliding rods away from the fixed shells respectively penetrate the two sliding rings and extend to the outside of the sliding rings, and the inner rings of the sliding rings are slidably connected to the outer surfaces of the sliding rods. The fixed rings can drive the sliding rings to slide on the outer surfaces of the sliding rods during movement, so that the fixed rings can only move along the sliding rods, effectively ensuring the stability of the fixed rings during movement, and effectively avoiding the fixed rings from being deflected and stuck during movement, thereby avoiding affecting the normal installation of the tube shell.

[0009] Furthermore, one end of each sliding rod away from the fixed shell is fixedly connected to a limit ring, and the diameter of the limit ring is greater than the diameter of the slip ring. The sliding rod can be limited by the limit ring, effectively preventing the slip ring from being scratched from the outer surface of the sliding rod during the sliding process, thereby avoiding affecting the subsequent normal use of the tube shell.

[0010] Furthermore, an operation indicator board is fixedly connected to the upper surface of the fixed shell, and instructions for use are engraved on the outer surface of the operation indicator board. Workers can read the instructions for use on the operation indicator board before installation, so that they can operate according to the correct operating method, effectively avoiding installation failure of the tube shell due to improper operation.

[0011] Furthermore, the inner circle of the tube shell body is fixedly connected with heat-insulating cotton, and the use of the heat-insulating cotton can further increase the heat-insulating effect of the tube shell and improve the overall practicality of the tube shell.

[0012] Furthermore, the inner circle of the thermal insulation cotton is fixedly connected with an insulation layer, the inner circle of the insulation layer is provided with a pipeline body, and the insulation layer and the thermal insulation cotton cooperate with each other to further protect and insulate the pipeline body to avoid temperature loss.

[0013] The working principle and beneficial effects of the utility model are:

[0014] 1. In the utility model, two fixed shells are fixed to the outer surface of the tube shell body by bolts. Then the staff rotates the threaded rod, and the screw ring drives the fixed ring to move to both sides of the fixed shell. The two sides of the fixed shell are fixed by the fixed ring to complete the installation and fixation of the tube shell. The tube shell can be fixed evenly as a whole, and the length of the tube shell can be adjusted and fixed as a whole, which makes installation and fixation more convenient and facilitates later disassembly and installation.
