Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a cement inner cylinder hanging piece assembly. Background Art

[0002] The cement preheater can make full use of the heat enthalpy of the hot air flow discharged from the rotary kiln and the decomposition furnace to heat the raw material, so that the raw material and the hot air flow can exchange heat, preheat the raw material and decompose part of the carbonate. Then the raw material enters the decomposition furnace or the rotary kiln to continue heating and decomposition, and calcined into clinker. The air flow after heat exchange is separated and discharged. The cement inner tube hanging piece is a heater component used to hang inside the cement preheater, which is used to heat the material to achieve the preheating and decomposition reaction of the material.

[0003] At present, the existing cement inner tube hanging sheet assemblies on the market have the following disadvantages:

[0004] (1) During the preheating process, due to the gaps between the existing inner tube hanging sheet assemblies, some raw materials will penetrate and cause damage to the inner wall of the preheater, thus reducing the service life of the preheater;

[0005] (2) After the preheater is used for a long time, the preheater hanging plate needs to be replaced. The existing cement inner tube hanging plate assembly is not convenient for quick removal and installation, which increases the workload of the staff. Summary of the invention

[0008] As a further improvement of the above scheme, the upper hanging plate assembly includes fixing bolts threadedly connected to the top of the fixing ring in an annular array, and the surface of the fixing bolts is threadedly connected with a fixing plate, and one side of the fixing plate is fixedly connected to the upper hanging plate.

[0009] Through the above technical solution and the setting of the fixing plate, the purpose of connecting the upper hanging plate with the fixing ring is achieved.

[0011] Through the above technical solution and the setting of the connecting ring, the purpose of connecting the upper hanging plate and the lower hanging plate is achieved.

[0012] As a further improvement of the above solution, an upper through hole is provided inside the upper hanging plate, and a lower through hole is provided inside the lower hanging plate.

[0013] Through the above technical solution, by setting the upper through hole and the lower through hole, the purpose of increasing the surface area of ​​the hanging piece and thus improving the heat conduction efficiency is achieved.

[0014] As a further improvement of the above solution, the material of the upper hanging plate is titanium alloy, and the material of the lower hanging plate is titanium alloy.

[0015] Through the above technical solution, the titanium alloy has good heat resistance and strength, and the purpose of increasing the service life of the hanging piece is achieved through the setting of the titanium alloy material.

[0016] As a further improvement of the above solution, a connecting ring is overlapped on one side of the upper hanging piece, a connecting ring is overlapped on one side of the lower hanging piece, and the bottom of the upper hanging piece is overlapped on the lower hanging piece.

[0019] The utility model provides an upper hanging sheet assembly. When installing the hanging sheet assembly, the staff puts the fixing ring and the fixing sheet in corresponding positions. The staff screws in the fixing bolts to connect the fixing ring to the cement preheater. At the same time, the upper hanging sheet is connected to the fixing sheet and the fixing ring. When the upper hanging sheet assembly is installed, the upper hanging sheet fits with the wall surface of the inner cylinder of the preheater. At the same time, each upper hanging sheet fits with each other, thereby preventing the raw material from infiltrating and causing damage to the inner wall of the preheater, thereby improving the service life of the preheater.

[0020] The utility model provides a connection assembly. After the preheater is used for a long time, the staff can separate the inner cylinder hanging piece assembly from the preheater as a whole by loosening the fixing bolts, unscrewing the lower connection bolts to separate the lower hanging piece from the connection ring, and then unscrewing the upper connection bolts to separate the connection ring from the upper hanging piece, so as to quickly disassemble and replace the upper hanging piece and the lower hanging piece, so that the cement inner cylinder hanging piece assembly can be quickly disassembled and installed, thereby reducing the workload of the staff.
