Description

Technical Field

[0001] The present invention relates to the technical field of furnace lining construction, and particularly relates to an anchoring device for lining construction of thermal equipment. Background Art

[0002] At present, the anchoring device is a kind of fastener connecting the inner side wall of the equipment and the refractory lining material. The material is different metal materials, and there are various specifications for the requirements of the temperature of the predetermined insulation layer thickness. It is widely used in industries such as petrochemical, steel, non-ferrous metal smelting, etc. It has good properties such as anti-aging, anti-temperature sudden change, cold resistance and heat resistance, pressure resistance, good tensile performance, not easy to deform after fixation, moisture-proof, shock absorption, etc.

[0003] The commonly used anchoring devices are of two types: expanded metal lathing and anchor bolts. In actual applications, there are more or less the following problems with these two forms of anchoring methods: 1) The welding density of the anchor bolts is high. Since the single anchor bolt is welded point-to-point with the inner side wall of the equipment, the workload of marking the welding points in advance is large; in addition, when arranged densely, affected by the form of the anchor bolts, it is difficult for welders to carry out welding; secondly, the single anchor bolt is in single-point welding contact with the inner side wall of the equipment, and the fixation of the refractory lining is also in point contact. In the case of a small contact surface and low welding point quality, the anchor bolts are easily detached by a slight external force, affecting the lining construction quality and progress, and it is even more difficult to carry out welding construction on the inclined inner side wall, affecting the welding quality and seriously reducing the later service performance; 2) When welding the expanded metal lathing, it is not easy to fix it to the inner side wall of the equipment, which easily affects the welding quality of the welding points.

[0004] How to develop an anchoring device for lining construction of thermal equipment, which can adapt to the construction operations of the inner side wall linings of different thermal equipment, is convenient for the welding and installation of the anchoring device, and at the same time improves the connection stability between the anchoring device and the inner side wall of the thermal equipment has become a technical problem that needs to be solved urgently by those skilled in the art. Summary of the Invention

[0005] The purpose of the present invention is to provide an anchoring device for lining construction of thermal equipment to solve the problems listed in the background art.

[0006] To solve the above technical problems, the present invention adopts the following technical solutions:

[0007] An anchoring device for lining construction of a thermal equipment of the present invention includes an installation strip, through slots are arranged at equal intervals on the installation strip, a plurality of connecting strips are installed at equal intervals on the side wall of the installation strip, an anchor body is slidably installed in the through slots, and the length of the connecting strip corresponds to the axial interval length of the anchor body.

[0008] Preferably, the installation strip is bent along the inner wall of the thermal equipment, and the installation strip is welded to the inner wall of the thermal equipment.

[0009] Preferably, the anchor body includes a casing, one end of the casing is fixedly installed with a contact plate, the inner side of the contact plate abuts against the installation strip, and the outer side of the contact plate is welded to the inner wall of the thermal equipment;

[0010] The outer side wall of the casing is slidably connected with the through groove.

[0011] Preferably, through holes are evenly spaced on the side wall of the casing.

[0012] Preferably, the other end opening of the casing is threadedly connected to one end of a bolt, and a stop head is installed at the other end of the bolt.

[0013] Preferably, the shape of the stop head is V-shaped, S-shaped or mountain-shaped.

[0014] Compared with the prior art, the beneficial technical effects of the present invention are:

[0015] For the lining construction anchoring device of a thermal equipment of the present invention, welding both ends and the middle casing of the installation strip to the inner side wall of the thermal equipment can complete the preliminary fixing operation of the casing on the installation strip, which is convenient for construction workers to quickly install and align. After the preliminary fixed installation is completed, the remaining un-welded casings and installation strips are welded and fixed to the inner side wall of the thermal equipment. Even if a single casing is separated from the inner side wall of the thermal equipment, the casing can be pulled under the action of the installation strip to prevent the lining from separating from the inner side wall of the thermal equipment;

[0016] By welding both ends of the connecting strip to two installation strips with anchor bodies slidably installed, the installation density of the anchor bodies on the inner side wall of the thermal equipment is ensured. At the same time, the installation strip is welded to the connecting strip and all are welded to the inner side wall of the thermal equipment, realizing the fixing operation of the anchor bodies in the radial and axial directions along the inner side wall of the thermal equipment, ensuring the connection stability of the anchor bodies, avoiding the separation of the anchor bodies from the inner side wall of the thermal equipment. Further, it prevents the generation of air pockets between the lining and the inner side wall of the thermal equipment, and greatly improves the installation efficiency of the internal anchoring device of the thermal equipment;

[0017] At the same time, the installation strip can be bent along the inner side wall of the thermal equipment to achieve environmental adaptability during the lining construction process of the inner side walls of different thermal equipments. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0025] As Figures 1-4 shown, an anchoring device for lining construction of a thermal equipment includes a mounting strip 1. Through - slots 3 are equidistantly arranged on the mounting strip 1. A plurality of connecting strips 2 are equidistantly installed on the side wall of the mounting strip 1. An anchor body is slidably installed in the through - slot 3, and the length of the connecting strip 2 corresponds to the axial interval length of the anchor body;

[0026] The mounting strip 1 is bent along the inner wall of the thermal equipment, and the mounting strip 1 is welded to the inner wall of the thermal equipment;

[0027] During installation, welding the two ends and the middle sleeve of the mounting strip to the inner side wall of the thermal equipment can complete the preliminary fixing operation of the sleeve on the mounting strip, facilitating rapid installation and alignment by construction workers. After the preliminary fixing installation is completed, welding and fixing the remaining sleeves that have not been welded. Further, fixing the mounting strip to the inner side wall of the thermal equipment. Even if a single sleeve is separated from the inner side wall of the thermal equipment, the sleeve can be pulled under the action of the mounting strip, preventing the lining from detaching from the inner side wall of the thermal equipment;

[0028] At the same time, according to the layout density of the anchoring device determined by the design drawings, control the length of the connecting strip. Weld the two ends of the connecting strip to two mounting strips on which anchor bodies are slidably installed, ensuring the installation density of the anchor bodies on the inner side wall of the thermal equipment. At the same time, weld the mounting strip and the connecting strip, and all are welded to the inner side wall of the thermal equipment, realizing the fixing operation of the anchor bodies in the radial and axial directions along the inner side wall of the thermal equipment, ensuring the connection stability of the anchor bodies, preventing the anchor bodies from detaching from the inner side wall of the thermal equipment, and further preventing the occurrence of air pockets between the lining and the inner side wall of the thermal equipment;

[0029] Furthermore, when welding the connecting bars in the axial direction, only the side wall of the installation bar needs to be welded to the connecting bar, and then the welding construction operation can be completed, realizing an assembled installation method, which greatly improves the installation efficiency of the anchoring device inside the thermal equipment.

[0030] Specifically, the anchor body includes a sleeve 4. One end of the sleeve 4 is open and fixedly installed with a contact plate. The inner side surface of the contact plate abuts against the installation bar 1, and the outer side surface of the contact plate is welded to the inner wall of the thermal equipment;

[0031] The outer side wall of the sleeve 4 is slidably connected to the through groove 3.

[0032] Specifically, through holes 5 are equidistantly arranged on the side wall of the sleeve 4. The other end of the sleeve 4 is open and threadedly connected to one end of a bolt 6, so that the contact area between the sleeve and the bolt is small. At the same time, it is also convenient for the lining to be filled in the cavity formed by the sleeve and the bolt, and heat transfer along the anchoring device to the outer wall of the thermal equipment can be reduced;

[0033] At the same time, the size of the contact plate is larger than that of the through groove. On the one hand, it is convenient for the contact plate to be welded to the inner side wall of the thermal equipment. On the other hand, when the contact plate is separated from the inner side wall of the thermal equipment, the installation bar can limit the sleeve through the contact plate. By adopting a double - fixing and double - insurance method, the sleeve can be prevented from separating from the inner side wall of the contact plate. Further, the generation of cavities between the lining and the inner side wall of the thermal equipment can be avoided;

[0034] The sliding of the outer side wall of the sleeve in the through groove is convenient for the construction personnel to finely adjust the installation position of the sleeve, ensuring that the layout density and layout spacing of the sleeves are consistent. Further, the aesthetics and standardization of the construction are improved.

[0035] Specifically, a stop head 7 is installed at the other end of the bolt 6. The shape of the stop head 7 is V - shaped, S - shaped or mountain - shaped, which is convenient for the construction personnel to select a suitable stop head according to different thermal equipment to complete the construction operation of the equipment - specific lining, so as to ensure that the anchor can adapt to different lining pouring forms;

[0036] For example, the V - shaped stop head cooperating with the bolt can be applied to thermal equipment with high - wear - resistant single - layer lining requirements; the mountain - shaped stop head cooperating with the bolt can fix the turtle - back mesh and complete the construction of high - wear - resistant single - layer lining and heat - insulating high - wear - resistant double - layer lining for the thermal equipment, ensuring the adaptability to different lining construction processes for different thermal equipment.
