Description

Technical Field

[0001] This utility model relates to the field of boiler flame television technology, and in particular to a rapid scorch removal device for boiler flame television. Background Technology

[0002] In modern industrial production, boilers are key equipment, and their safe and stable operation is of paramount importance. Boiler flame television, as a device that can monitor the combustion status of the flame inside the furnace in real time, has become an indispensable part of ensuring the efficient and safe operation of boilers. It organically integrates optical, mechanical, and electronic technologies, and transmits images inside the furnace through an optical system to the camera target through a lens. After being converted into video signals, it is transmitted to the monitor in the central control room, allowing operators to intuitively understand the fuel combustion situation inside the furnace and promptly detect and take measures when the boiler is ignited, operating at low load, or when there is a fault in the fuel delivery system.

[0003] To prevent ash and slag buildup on the lens of existing boiler flame television systems from affecting image quality, air blowing devices are typically used for cleaning and descaling. However, most current equipment uses a single air blowing direction, meaning that only specific areas can be cleaned, such as the downwind area. Due to factors like airflow direction and equipment structure, air blowing in a single direction cannot fully cover this area, resulting in the ash and slag buildup on the lens at the downwind end not being completely removed. Over time, this buildup accumulates on the lens at the downwind end, severely affecting image clarity and increasing the frequency and difficulty of lens maintenance. Utility Model Content

[0004] To overcome the problem that existing boiler flame televisions, due to their single-direction air blowing for lens cleaning and descaling, cannot completely remove ash and slag buildup at the downwind end of the lens, thus increasing the difficulty of lens maintenance, this utility model provides a rapid descaling device for boiler flame televisions.

[0005] The technical solution is as follows: A boiler flame television rapid coking device includes a boiler flame television assembly, a positioning frame assembly, a feed cylinder, a slide rail bracket, and a limiting assembly; the positioning frame assembly is provided at the rear end of the boiler flame television assembly; the feed cylinder is provided inside the positioning frame assembly; the slide rail bracket is provided above the positioning frame assembly; limiting assemblies are provided on both sides of the slide rail bracket; the boiler flame television assembly includes a flame television tube, a high-temperature resistant flame probe, a high-temperature resistant pulse jet head, an explosion-proof plate, and a pulse jet connecting pipe.

[0006] Furthermore, a high-temperature resistant flame probe is provided on the front end face of the flame television tube; high-temperature resistant pulse jet heads are provided on all four sides of the outer side of the high-temperature resistant flame probe, and the nozzles of the high-temperature resistant pulse jet heads are aligned with the high-temperature resistant flame probe.

[0007] Furthermore, an explosion-proof plate is provided at the rear end of the flame TV tube, and the explosion-proof plate is fixedly connected to the flame TV tube. The rear end face of the explosion-proof plate is fixedly connected to the telescopic cylinder rod bolt of the feed cylinder. A pulse jet connection pipe is provided at the rear end of the explosion-proof plate, and the pulse jet connection pipe is connected to the high-temperature resistant pulse jet head pipeline.

[0008] Furthermore, the positioning frame assembly includes a slide and positioning wheels; the slide is located above the feed cylinder; positioning wheels are located on both sides of the slide and are arranged at equal intervals.

[0009] Furthermore, the slide rail bracket includes a hanger, a connecting plate, and a lifting slide rail; a connecting plate is provided at the rear end of the feed cylinder, and the connecting plate is fixedly connected to the housing of the feed cylinder; a hanger is provided above the slide; a lifting slide rail is provided at the lower end of the hanger, and the lifting slide rail is fixedly connected to the lower end face of the hanger, and the slider on the upper end face of the slide is slidably connected along the lifting slide rail track.

[0010] Furthermore, the limiting component includes a base, a lifting cylinder, and a positioning pin; both sides of the hanger are provided with bases, and the bases and the hanger are fixedly connected by bolts.

[0011] Furthermore, a lifting cylinder is provided on the outer side of the base, and the lifting cylinder is fixedly connected to the base by bolts; a positioning pin is provided at the lower end of the lifting cylinder, and the positioning pin is fixedly connected to the cylinder rod of the lifting cylinder, and the positioning pin is limited to the gap between the lifting and lowering insertion of the positioning pin into the positioning wheel.

[0012] The beneficial effects are: This utility model realizes the function of removing dust and scorch from the high-temperature flame probe by pulse jetting through the high-temperature pulse jetting heads around the high-temperature flame probe. Since the high-temperature flame probe is equipped with high-pressure pulse jetting heads around it, dust will not accumulate on the lens of the high-temperature flame probe, thereby greatly improving the dust removal and scorch removal effect of the high-temperature flame probe and reducing the maintenance difficulty.

[0013] By setting up a feed cylinder and an explosion-proof plate, the feed cylinder drives the explosion-proof plate and the flame TV tube to move forward, thereby enabling the flame TV tube to be inserted into the furnace for endoscopic monitoring of the flame combustion, and the flame TV tube to be withdrawn from the furnace. This is to protect the flame TV tube and improve the ease of maintenance of the flame TV tube. The explosion-proof plate is used to protect the safety of the feed cylinder behind the boiler flame TV assembly and improve the heat insulation performance.

[0014] By incorporating a positioning frame assembly, a slide rail bracket, and a limiting assembly, the slide can slide along the hoisting slide rail when the feed cylinder adjusts the feed or retraction of the boiler flame television assembly. This improves the stability of the positioning frame assembly and the boiler flame television assembly. The lifting cylinder of the limiting assembly, in conjunction with the positioning pin, inserts into the gap between the positioning wheels to adjust and position the relative position of the slide and the hanger. Compared to traditional chain pushers or screw pushers, the feed cylinder of this invention offers faster advance or retraction speeds. Furthermore, the limiting assembly provides a positioning and braking function, effectively improving the efficiency of the advance and retraction adjustment of the boiler flame television assembly.

[0025] An explosion-proof plate 104 is provided at the rear end of the flame TV tube 101, and the explosion-proof plate 104 is fixedly connected to the flame TV tube 101. The rear end face of the explosion-proof plate 104 is fixedly connected to the telescopic cylinder rod of the feed cylinder 3 by bolts. A pulse jet connection pipe 105 is provided at the rear end of the explosion-proof plate 104, and the pulse jet connection pipe 105 is connected to the high-temperature resistant pulse jet head 103 pipeline.

[0027] The high-temperature flame probe 102 is equipped with high-temperature pulse jet heads 103 around its perimeter to perform pulse jet dust removal and descorching function. Since high-temperature pulse jet heads 103 are provided around the high-pressure pulse jet for the high-temperature flame probe 102, dust will not accumulate on the lens of the high-temperature flame probe 102, thereby greatly improving the dust removal and descorching effect of the high-temperature flame probe 102 and reducing the maintenance difficulty.

[0028] With the feed cylinder 3 and explosion-proof plate 104, the feed cylinder 3 drives the explosion-proof plate 104 and the flame television tube 101 to move forward, thereby realizing the insertion of the flame television tube 101 into the furnace for endoscopic monitoring of the flame combustion, and the withdrawal of the flame television tube 101 from the furnace. This is to protect the flame television tube 101 and improve the ease of maintenance of the flame television tube 101.

[0033] With the positioning frame assembly 2, slide rail bracket 4, and limiting assembly 5, when the feed cylinder 3 adjusts the feed or retraction of the boiler flame television assembly 1, the slide 201 slides along the hoisting slide rail 403, thereby improving the movement stability of the positioning frame assembly 2 and the boiler flame television assembly 1. The lifting cylinder 502 of the limiting assembly 5 drives the positioning pin 503 to insert into the gap between the positioning wheels 202 to achieve the adjustment and positioning function of the relative position of the slide 201 and the hanger 401. Compared with the traditional chain pusher or screw pusher, the feed cylinder 3 of this utility model has a faster advance or retraction speed.
