Description

Technical Field

[0001] This utility model relates to the field of waste incinerators, and in particular to a waste incinerator camera descorching device. Background Technology

[0002] To monitor the combustion of materials inside a waste incinerator, cameras are typically installed on the furnace wall. Due to the high temperature inside the incinerator, protective sleeves are installed to protect the cameras from overheating and damage. Compressed air is continuously circulated inside the protective sleeves for cooling, resulting in a localized low-temperature zone near the air outlet at the end of the sleeve. Furthermore, the fly ash produced during combustion at high temperatures is in a molten state. When flue gas carrying molten ash particles flows at high speed past the end of the sleeve, the airflow bypasses the camera and continues flowing. However, some ash particles, due to inertia, directly impact the surface of the camera's protective sleeve. Simultaneously, due to the presence of the low-temperature zone near the air outlet, the molten ash particles solidify again, forming coke that adheres to the outside of the sleeve, especially around the air outlet. As the coke accumulates, it gradually obstructs the camera's view, affecting its long-term stable operation and increasing the workload of manual decoking.

[0003] Existing camera descaling devices typically fix the scraper inside the furnace. Descaling is performed manually or automatically when coking is observed around the camera lens aperture. This exposes the scraper, like the camera itself, to prolonged exposure to high-temperature flue gas, leading to coking on the scraper. Once the scraper is coked, its surface cannot adhere tightly to the camera surface, severely impacting the descaling effect. Current technologies generally use flat scrapers, which can easily push scraped-off coke into the camera lens aperture, affecting normal camera operation and potentially damaging the lens. Furthermore, existing descaling devices can only clean a small area where the camera lens aperture and scraper are in contact, failing to clean the protective sleeve further away. Prolonged neglect leads to thicker and more compacted coke residue, making complete removal difficult. This residual coke, under the influence of high-temperature flue gas, becomes a new coking point, accelerating re-coking. Additionally, the current furnace-based design is inconvenient to install, and if the descaling device malfunctions, the camera must be removed, making repair and replacement difficult. Summary of the Invention

[0004] The purpose of this utility model is to provide a descaling device for a waste incinerator camera, which avoids the self-coking phenomenon of the scraper in existing descaling devices, improves the descaling effect of the device, extends the descaling cycle, increases the usability of the camera, improves the adaptability of the descaling device, avoids damage to the camera and affects its normal operation during descaling, and all descaling devices are arranged outside the furnace for easy installation, replacement and maintenance, without affecting the normal operation of the camera.

[0005] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a waste incinerator camera scorch removal device, comprising:

[0006] The base casing is installed on the outside of the waste incinerator;

[0007] The camera lens assembly, through the driving component, enables observation of the incinerator from inside the base casing and exit from the base casing;

[0008] It also includes a lens clearing assembly for cleaning focus buildup on the camera lens assembly before it enters the base protector, including:

[0009] A fixed bracket is installed on the base casing. The fixed bracket includes an upper bracket and a lower bracket arranged symmetrically at the top and bottom. Two adjusting screws are symmetrically arranged on the left and right sides between the upper bracket and the lower bracket. The upper end of the adjusting screw is connected to the upper bracket frame, and the lower end of the adjusting screw is connected to the lower bracket frame.

[0010] Two scraper blades (4) are symmetrically arranged on the adjusting screw. The two ends of the scraper blades are clamped in the middle of the adjusting screw by the adjusting springs that are fitted on the adjusting screw. A channel is formed at the center between the two scraper blades for the protective sleeve to pass through. When the protective sleeve enters and exits the waste incinerator, the two scraper blades can scrape off the coking on the camera lens assembly under the elastic force of the spring.

[0011] Furthermore, the fixed bracket is connected to the clamp via a connecting rib plate. The clamp consists of two plates, upper and lower, which are tightened by fastening bolts and are clamped onto the base casing.

[0012] Furthermore, a silicone pad is provided between the clamp and the base sleeve.

[0013] Furthermore, the adjusting screw has a smooth middle section, threaded ends, and a limiting ring at the center.

[0014] Furthermore, an adjusting nut is fitted on both the top and bottom of the adjusting screw, clamping the two adjusting springs in the middle.

[0015] Furthermore, a reinforcing steel strip is provided on the outer side of the scraper.

[0016] Furthermore, the head of the protective sleeve has a hemispherical structure, a mirror hole is opened on the bottom side, and the body is cylindrical.

[0017] Furthermore, the scraper has two hexagonal thin nuts at both ends and a stainless steel strip in the middle. The stainless steel strip has an arc-shaped protrusion in the middle with a radius that is 1.2-1.4 times the radius of the protective sleeve.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] First, the coking removal device of this application is set outside the furnace, and the camera is a moving part. The camera is remotely controlled to be put into and taken out or manually operated to remove coke, which avoids the self-coking phenomenon of the scraper of the existing coking removal device, extends the coking removal cycle, facilitates installation, replacement and maintenance, and does not affect the normal operation of the camera.

[0020] Secondly, a silicone pad is placed between the clamp and the base casing to increase the friction between the clamp and the base casing and enhance the stability of the installation. Under the high temperature radiation of the furnace, the outer surface temperature of the base casing is high. The silicone pad has a temperature resistance of over 200℃ and plays a certain role in heat insulation, preventing heat from being transferred to the surface of the coking device and burning the operators. In addition, the silicone pad can also play a shock absorption role, preventing the furnace wall vibration from being transmitted to the scraper and damaging the camera.

[0021] Third, a limiting ring is welded to the center position of the adjusting screw to limit the position of the upper and lower scraper blades and prevent the scraper blades from interfering with each other.

[0022] Fourth, the tension of the adjusting spring can be adjusted by adjusting the adjusting nut to adapt to different coking speeds and coking thicknesses. When the coking speed is fast or the coking is soft, the adjusting spring can be loosened appropriately, and when the coking speed is slow or the coking is hard, the adjusting spring can be tightened appropriately.

[0023] Fifth, while cleaning the lens aperture, the defocusing device can also clean the protective sleeve around the lens aperture at the same time, resulting in a larger defocusing range and better defocusing effect. This reduces residual coking points, extends the defocusing cycle, and increases the usability of the camera. Attached Figure Description
