Description

Technical Field

[0001] This invention belongs to the field of high-pressure boiler technology, and in particular relates to a membrane wall coating device based on a high-pressure boiler. Background Technology

[0002] Membrane walls are in contrast to traditional heavy-duty furnace walls. They refer to boiler walls that are made of welded sheets of pipes and fins. Large boiler water-cooled walls are basically membrane walls, which have advantages such as simplicity and saving steel.

[0003] Existing methods for coating membrane wall surfaces, due to the parallel welding of pipes and the presence of internal grooves between them, cannot be applied using coating equipment. This results in low automation, requiring manual coating operations, which are labor-intensive, inefficient, and fail to meet practical application needs. Summary of the Invention

[0004] The purpose of this invention is to provide a membrane wall coating device based on a high-pressure boiler. By using a bottom plate, end seat, traveling shaft frame, coating roller, connecting sleeve and rotating end shaft in combination, it solves the problems of high manual labor intensity and low automation in the existing membrane wall coating operation of boilers.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] This invention relates to a membrane wall coating device for a high-pressure boiler, comprising a base plate with end seats inserted at both ends; a traveling shaft frame rotatably connected between the two surfaces of the end seats; an electric telescopic rod fixedly connected to both ends of the base plate; the telescopic end of the electric telescopic rod fixedly connected to the end seat; a coating roller rotatably connected between the two ends of the bottom of the base plate; a connecting sleeve rotatably connected between the two ends of the top of the base plate; a rotating end shaft inserted into both ends of the connecting sleeve; and a rotating end shaft rotatably connected to the side of the end seat. The end of the rotating shaft meshes with the top of the traveling shaft frame for transmission; a servo motor is fixedly mounted on the top of the bottom plate; the rotating shaft of the servo motor is connected to the connecting sleeve via a first transmission belt; a second transmission belt is connected between the two circumferential sides of the connecting sleeve and the two ends of the coating roller; a paint tank is mounted on the top of the bottom plate; a connecting conduit is connected to the outer circumferential side of the coating tank; a spraying horizontal pipe is mounted at the other end of the connecting conduit; spray nozzles are arranged in a linear array on the outer circumferential side of the spraying horizontal pipe and along the side edge of the bottom plate; a delivery pump is mounted on the circumferential side of the connecting conduit.

[0007] As a preferred embodiment of the present invention, the bottom of the bottom strip plate is provided with an arc-shaped cover plate that cooperates with the coating roller; both ends of the bottom of the bottom strip plate are provided with end ears that are rotatably connected to the two ends of the coating roller; both ends of the bottom strip plate are provided with insertion holes; and the surface of the bottom strip plate is provided with two brackets that are rotatably connected to the connecting sleeve.

[0008] As a preferred embodiment of the present invention, the side of the end frame is provided with a plug rod that mates with the plug hole; the side of the end frame is vertically fixed with an end side plate; the side of the end frame is rotatably connected to the rotating end shaft.

[0009] As a preferred embodiment of the present invention, the traveling axle frame includes a shaft; the bottom end of the shaft is provided with a U-shaped guide wheel; the outer circumferential side of the U-shaped guide wheel is provided with an anti-slip groove in an annular array; and the top end of the shaft is provided with a first bevel gear.

[0010] As a preferred embodiment of the present invention, both ends of the coating roller are provided with a first transmission wheel that cooperates with the second transmission belt; the circumferential side of the coating roller is provided with multiple U-shaped structures; and coating brushes are arranged in a circular array on the circumferential side of the coating roller and inside the U-shaped structures.

[0011] As a preferred embodiment of the present invention, the two ends of the connecting sleeve are inserted into the rotating shaft; the inner walls of both ends of the connecting sleeve are provided with limiting guide ribs; the outer peripheral sides of both ends of the connecting sleeve are provided with second transmission wheels that cooperate with the second transmission belt; and the outer peripheral side of one end of the connecting sleeve is provided with a third transmission wheel that cooperates with the first transmission belt.

[0012] As a preferred embodiment of the present invention, the outer peripheral side of the rotating end shaft has a limiting guide groove that cooperates with the limiting guide rib; the other end of the rotating end shaft is provided with a second bevel gear that meshes with the first bevel gear.

[0013] The present invention has the following beneficial effects:

[0014] 1. This invention utilizes the combined use of a base plate, end seat, traveling shaft frame, coating roller, connecting sleeve, and rotating end shaft. When the servo motor rotates, the coating roller rotates under the action of the second transmission belt to perform coating operations on the surface of the membrane wall and the inside of its grooves. The connecting sleeve rotates and drives the rotating end shafts at both ends to rotate. The rotating end shafts mesh with the top of the traveling shaft frame, causing the two traveling shaft frames to rotate, thereby driving the entire device to move along both sides of the membrane wall, automatically performing coating operations on the membrane wall. This reduces the intensity of manual labor, has a high degree of automation, and improves the efficiency of membrane wall surface coating operations.

[0015] 2. In this invention, as the entire device moves along the membrane wall, the delivery pump transfers the paint from the paint tank to the spraying horizontal pipe through the connecting conduit. Under the action of the nozzle, the paint is evenly sprayed onto the surface of the membrane wall, which facilitates the coating roller to perform the coating operation. Its structure is simple, the installation is convenient, and it meets the needs of practical use.
