Description

Technical Field

[0001] This utility model relates to the field of cement kiln construction, and in particular to a fixing structure for fixing a lightweight heat-insulating lining in a cement kiln system. Background Technology

[0002] There are two main methods for fixing lightweight thermal insulation linings during the original on-site furnace construction: one is to glue the lightweight thermal insulation lining to the shell with glass glue and then fix it with iron wire; the other is to fix the lightweight thermal insulation lining tightly to the shell with 3-5mm soft round steel to the anchor, and then weld the round steel to the anchor for fixation.

[0003] Existing technical drawbacks: 1. The lightweight insulating linings at the top of various parts of the kiln system cannot adhere tightly to the shell. During refractory casting, the lightweight insulating linings are prone to detaching from the shell, affecting construction quality. 2. The numerous construction procedures lead to slow construction, affecting efficiency and indirectly increasing costs. 3. With the application and promotion of advanced materials, the owner company has extensively used nano-insulation panels in systems such as grate coolers, kiln hoods, tertiary air ducts, and preheaters in recent years. However, in actual construction, there are instances where the tops of grate coolers, kiln hoods, cyclones, and decomposers cannot adhere tightly to the shell. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Example 1, such as Figure 1-5 As shown, a fixing structure for fixing a lightweight heat-insulating lining in a cement kiln system includes a lining fixing body structure. The lining fixing body structure is divided into an integrally formed supporting extension part and a central snap-fit ​​limiting part. The supporting extension part includes an outer peripheral body 1, an inner support body 2, an inner rib group 3 provided between the outer peripheral body and the inner support body, and a snap-fit ​​notch 4 provided between the outer peripheral body and the inner support body. The central snap-fit ​​limiting part includes a C-shaped clamp 5 and an injection section 6 provided at the outer end of the C-shaped clamp and connected to the snap-fit ​​notch of the outer peripheral body and the inner support body.

[0025] The C-shaped clamp is provided with a clamping platform 7 on both the front and back sides, and the clamping platform 7 is C-shaped.

[0026] A trapezoidal material receiving hole 8 is formed between the outer periphery, the inner support body, and the inner rib group.

[0027] The outer periphery, inner support, material receiving hole, and the upper edge of the front and back sides of the inner rib assembly are each provided with a raised edge 9.

[0028] Example 2, as Figure 6-7 As shown, a fixing structure for fixing a lightweight heat-insulating lining in a cement kiln system includes a lining fixing body structure, which is divided into an anchor main connection structure and a side wing fixing structure designed integrally with the anchor main connection structure.

[0029] The anchor body connection structure includes a central bracket seat 10, an upper extension 11 located on the upper part of the central bracket seat, an insertion fixing hole 12 located at the center of the central bracket seat, an insertion notch 13 located on the outer periphery of the insertion fixing hole, an inner fixing hole group 14 evenly distributed in the central bracket seat, an extension platform 15 located on the central bracket seat outside the insertion fixing hole, and a side wing fixing structure located on the outer side of the central bracket seat.

[0030] The side wing fixing structure includes extended ear seats 16 on both sides of the central pendant seat and extended fixing holes 17 in each extended ear seat.

[0031] The extension fixing hole 17 is provided with a side end anchor 20, the inner part fixing hole group 14 is provided with a main body side wall anchor 19, and the inlet fixing hole 12 is provided with a main body anchor limiting sleeve 18, which are used in conjunction with the fixing structure for fixing the lightweight heat insulation lining in the above-mentioned cement kiln system.

[0032] Nano-insulation panels are widely used in systems such as grate coolers, kiln hoods, tertiary air ducts, and preheaters. However, in actual construction, there is a problem where the tops of grate coolers, kiln hoods, cyclones, and decomposition furnaces cannot be tightly adhered to the shell. Ordinary calcium silicate boards can be fixed to the shell by applying silicone sealant or high-temperature mortar and binding with thin iron wire; however, due to the outer plastic film packaging of nano-insulation panels, silicone sealant or high-temperature mortar cannot be applied for adhesion, and only binding with thin iron wire is possible. This method is insufficient for achieving a tight fit when installing nano-insulation panels on the tops of tertiary air duct bends, kiln hoods, cyclones, grate coolers, and large bends in decomposition furnaces. Therefore, to ensure the insulation effect of nano-insulation panels, standardize construction requirements, and guarantee their performance, the following construction requirements for nano-insulation panels in relevant locations are hereby specified:

[0033] (1) When constructing the top of the tertiary air duct bend, the top of the kiln head hood, the top of the cyclone separator, and the top of the large bend of the decomposition furnace, the anchors must be welded neatly and with appropriate spacing. Taking a 200*200mm long and wide nano-insulation board as an example: the construction party should draw the welding spacing line in advance when welding the anchors. The spacing should be slightly larger than the length of the nano-insulation board (the optimal size is 205x205mm, and the maximum welding size is 210x210mm). When attaching the nano-insulation board, it should be tightly attached to the shell. If a double-layer nano-insulation board is used, transparent tape can be used to wrap the two nano-insulation boards together, and clips can be used for fixing.

[0034] (2) The production size of the nanoplate is adjusted according to the spacing of the anchors. First, determine the spacing of the anchors to determine the production size of the nanoplate.

[0035] (3) Design a special nano-board for sealing gaps and construct it according to the actual site conditions.

[0036] (4) The production size of the nanoplate should be adjusted according to the spacing of the anchors, rather than the size of the nanoplate. For example, if the spacing of the anchors is 200x200, it is recommended that the production size of the nanoplate be 195x195. 3. Produce special nanoplates for sealing gaps, such as sealing plates with about 5 meters per cubic meter, with two specifications of 10mm and 20mm width.

[0037] Advantages: 1. Ensures the thermal insulation effect of the nano-insulation board, standardizes construction requirements, and guarantees the performance of the nano-insulation board. 2. Solves the problem of nano-insulation boards not being able to fit tightly against the shell of grate coolers, kiln heads, cyclones, and decomposition furnaces during actual construction. 3. Solves the problem of large gaps in nano-boards during actual construction. It solves the problem of cement kiln insulation materials not fitting tightly against the shell, facilitating rapid on-site construction and ensuring comprehensive quality control of refractory materials. It saves on-site construction time and allows lightweight insulation materials to achieve better insulation effects.
