Description

Technical Field

[0001] The utility model relates to a portable furnace cleaning device. Background Art

[0002] The main fuels of lithium bromide burners are natural gas and heavy oil. Now the fuel of bromide refrigeration machine is mainly natural gas. The structure of the high-pressure generator of direct-fired lithium bromide absorption refrigeration unit is similar to that of a cylindrical fire tube boiler. The combustion takes place in the furnace tube. The flue gas enters the furnace body from the furnace tube and is then discharged to the chimney through the flue.

[0003] When the gas volume and air volume do not match, or smoke exhaust is insufficient, carbon deposits will occur in the furnace. The traditional method of cleaning the furnace is to use a soft shaft to drive a brush for cleaning or to use chemicals for cleaning. The disadvantage is that the soft shaft driving the brush for cleaning will cause smoke and dust to drift in the air, causing dust damage to the cleaning personnel, and chemical cleaning will corrode the furnace structure.

[0014] Preferably, two support columns are provided, and the two support columns are evenly distributed along the circumferential direction between the scraper plate and the connecting tube.

[0015] Beneficial technical effects of the utility model:

[0016] The cleaning head provided by the utility model conforms to the internal shape of the furnace, and the scraper plate can contact the inner wall of the furnace. By providing an extension tube, the cleaning head can penetrate into the furnace, and the scraper plate can be used to scrape off large particles of soot on the inner wall of the furnace, thereby ensuring the cleaning effect. Threaded connections and sealing rings are used between the components to enhance the sealing of the structure and prevent dust leakage. At the same time, the flexible connection hose configuration allows for adapting to operating requirements at different angles, so that cleaning work can be carried out flexibly. Through the convenient assembly and disassembly design, as well as the assistance of the flue gas recovery device and the dust suction fan, not only the cleaning efficiency is improved, but also the safety of the operator and the protection of the environment are guaranteed.
