Description

Technical Field

[0001] The utility model relates to the field of boiler cooling, in particular to a temperature-control and safety-protection visible cleaning device for a molten steel jacket of an oxygen-enriched side-blowing furnace. Background Art

[0002] The oxygen-enriched side-blown furnace is a boiler commonly used in the lead-making field. During the operation of the oxygen-enriched side-blown furnace, a safety steel water jacket needs to be set on the outer periphery of the boiler to cool the boiler. As an important cooling device, the safety steel water jacket can ensure that the boiler operates within a safe temperature range. The stable operation of the safety steel water jacket helps to maintain the overall stability of the boiler system and reduce operational failures caused by temperature fluctuations. The cooling water in the safety steel water jacket will contain calcium, magnesium and other ions, and impurities will also be mixed in during the flow of cooling water. These ions and impurities are easily decomposed and precipitated at the bottom of the safety steel water jacket under high temperature and high pressure to form scale. In the existing technology, impurities are cleaned by opening a cleaning hole, but some impurities adhere to the bottom of the safety steel water jacket, and there are dead corners in the cleaning. If the impurities are not cleaned thoroughly, it will affect the cooling quality and increase the risk of boiler operation. Therefore, there is an urgent need for a visual cleaning device for the temperature-controlled safety steel water jacket of the oxygen-enriched side-blown furnace to clean the impurities in the dead corners of the safety steel water jacket and ensure the cooling quality of the safety steel water jacket.

The observation rod is arranged vertically to the security molten steel jacket. The miniature camera in the observation rod is perpendicular to the security molten steel jacket. The high-pressure water delivery pipe delivers high-pressure water to the nozzle through the cleaning pipe. The nozzle sprays water downward to wash away the impurities attached to the bottom of the security molten steel jacket and discharge them from the sewage outlet 14 at the bottom of the security molten steel jacket. The miniature camera is embedded in the observation rod. The miniature camera can rotate inside the observation rod. The rotation of the miniature camera drives the spotlight to rotate, which can illuminate the corner position inside the security molten steel jacket, making it easy to observe the scaling condition in the corners inside the security molten steel jacket. The embedded miniature camera can ensure that the observation rod is smoothly inserted into the security molten steel jacket. The spotlight is an LED strong light spotlight. The interior of the security molten steel jacket is a closed space. The use of an LED strong light spotlight can better illuminate the interior of the security molten steel jacket, making it convenient for the miniature camera to clearly observe the internal situation and accurately find the location of scale blockage for easy cleaning.

[0029] A triangular bracket 11 is provided at the lower end of the lower bracket. The triangular bracket can ensure the stability of the lower bracket, making it convenient for the operator to clean the safety steel water jacket. The cleaning pipe is rotatably connected to the mounting hole. The cleaning pipe needs to be rotated to ensure that the nozzle can clean every corner of the safety steel water jacket. A handle is connected to the cleaning pipe. Since the water pressure generated by the high-pressure water delivery pipe is large, the handle facilitates the operator to hold the cleaning pipe steady to achieve the best cleaning effect.

[0030] A locking mechanism 9 is provided on the cleaning pipe, which includes a clamp 901 that is sleeved on the outside of the cleaning pipe. Threaded holes 904 are provided on both sides of the clamp. A screw 902 is threadedly connected to each threaded hole. A buckle 903 is rotatably connected to one end of the screw. A water inlet and a water outlet are provided on the safety steel water jacket. Flanges are provided on the water inlet and the water outlet. The buckle is used to connect with the flange. The inner diameter of the buckle is larger than the edge of the flange.
