Description

Technical Field

[0001] This utility model relates to the field of soot blower technology, specifically to an online monitoring device for soot blower barrel temperature. Background Technology

[0002] A soot blower is a device used to remove ash from the heating surface of a boiler. It usually consists of components such as a soot blowing pipe and operating valves. It is generally installed on the furnace wall in the boiler furnace, horizontal flue, and tail flue. According to the structural type, it can be divided into several types such as gun type, rotary type, and telescopic type. According to the different media used, it can be divided into three categories: air soot blower, steam soot blower, and hydraulic soot blower.

[0003] For some sootblowers with long barrels, if the barrel's center of gravity deviates too far from the support point, it may become unstable, swaying up and down during blowing, which can easily lead to barrel bending and damage. Furthermore, sootblowers are crucial equipment in industrial production, and their operating status directly affects production efficiency and product quality. Potential problems such as overheating and abnormal temperature of the sootblower barrel can easily cause damage or safety accidents. Therefore, this paper proposes an online temperature monitoring device for sootblower barrels to address the aforementioned problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an online monitoring device for the temperature of a sootblower barrel, comprising a main body, a support mechanism above the main body, and a temperature monitoring mechanism on the main body;

[0006] The support mechanism includes a mounting plate, a mounting frame is fixedly connected to the top of the mounting plate, a dual-axis servo motor is fixedly connected to the inner top wall of the mounting frame, a threaded rod is fixedly connected to the output shaft of the dual-axis servo motor, a threaded block is threadedly connected to the threaded rod, a first connecting rod is fixedly connected to the right side of the threaded block, a first support block is fixedly connected to one side of the first connecting rod, a second connecting rod is fixedly connected to the left side of the threaded block, and a second support block is fixedly connected to one side of the second connecting rod.

[0007] The temperature monitoring mechanism includes a temperature sensor, a data transmission module is fixedly connected to the bottom of the mounting plate, a data processing module is fixedly connected to the bottom of the mounting plate, and a display module is fixedly connected to the bottom of the mounting plate.

[0008] Preferably, the main body includes a soot blower body, an inner gun barrel is installed on the left side of the soot blower body, an outer gun barrel is sleeved on the outside of the inner gun barrel, the first support block is in contact with the surface of the inner gun barrel, and the second support block is in contact with the surface of the outer gun barrel.

[0009] Preferably, the mounting plate is located above the outer gun barrel, and connecting pieces are bolted to the four corners of the mounting plate, allowing the mounting plate to be mounted on the wall via the connecting pieces.

[0010] Preferably, the opposite sides of the two threaded rods are rotatably connected to the front and rear sides of the inner wall of the mounting frame, and each of the two threaded rods is provided with a thread, the two thread sections having equal lengths and opposite directions.

[0011] With the above technical solution, since the two threaded sections are of equal length and opposite direction, the first support block and the second support block can move the same distance under the drive of the threaded block.

[0012] Preferably, a limiting block is fixedly connected to the top of the threaded block, and a limiting groove adapted to the moving trajectory of the limiting block is provided on the inner top wall of the mounting frame.

[0013] Through the above technical solution, the moving direction and moving distance of the threaded block are guaranteed by the combined restriction of the limiting block and the limiting groove, and the threaded block is prevented from rotating together with the threaded rod.

[0014] Preferably, the right side wall of the mounting frame is provided with a first through hole that matches the movement trajectory of the first connecting rod, and the left side wall of the mounting frame is provided with a second through hole that matches the movement trajectory of the second connecting rod. The difference between the distance from the end of the first connecting rod to the first support block and the distance from the end of the second connecting rod to the second support block is a fixed value, which is equal to the thickness of the outer barrel.

[0015] With the above technical solution, since the difference between the distance from the end of the first connecting rod to the first support block and the distance from the end of the second connecting rod to the second support block is equal to the thickness of the outer barrel, the threaded block can move the same distance to support the first support block and the second support block on the surfaces of the inner and outer barrels respectively.

[0016] Preferably, the temperature sensor is installed inside the inner barrel at one end near the body of the soot blower, and the temperature sensor is wirelessly connected to the data transmission module. The data transmission module, the data processing module, and the display module are connected by a cable.

[0017] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0018] First, this utility model uses a connecting piece to install the mounting plate on the wall. By starting the dual-axis servo motor, the two threaded rods rotate forward. Under the combined restriction of the limiting block and the limiting groove, the threaded block drives the two first connecting rods and the two second connecting rods to move relative to each other, pushing the first support block and the second support block on both sides to clamp the inner gun barrel and the outer gun barrel respectively, thus providing stable support for the inner gun barrel and the outer gun barrel.

[0019] Secondly, this utility model monitors the temperature of the inner barrel using a temperature sensor, transmits the monitored temperature information to the data transmission module, the data transmission module transmits the temperature information to the data processing module, the data processing module processes and analyzes the temperature information, and finally displays the temperature information on the display module for operators to view in real time.
