Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of anti-crust formation in the smoke chamber, in particular to an anti-crust formation smoke chamber for a cement kiln. Background Technique
[0002] In some areas of the cement kiln, especially at the kiln head and kiln tail, the temperature of the hot gas flow is relatively high, and it contains certain amounts of chemical substances such as alkali metals and sulfides. These substances may form crusts on the surface of the smoke chamber.
[0003] After retrieval, the patent publication number CN219914008U discloses an anti-crust formation smoke chamber, including a tail smoke chamber. A feed hopper is installed through the top of the tail smoke chamber. A smoke exhaust pipe is installed on one side of the tail smoke chamber. A kiln barrel is installed through the other side of the tail smoke chamber. A kiln head hood is installed on one side of the kiln barrel. An anti-crust formation mechanism is installed at the top end and the outer side inside the tail smoke chamber. A cleaning mechanism is installed through the bottom of the front end of the tail smoke chamber. The anti-crust formation mechanism includes a water tank. A water pump is installed through one side of the water tank. A water delivery pipe is connected and installed at the top of the water pump. Connecting pipes are installed at the end of the water delivery pipe and on the inner walls of the front, rear, and both sides of the tail smoke chamber near the top; the anti-crust formation smoke chamber of the present utility model is beneficial to preventing the inner wall of the tail smoke chamber from forming crusts, increasing the fluidity of air, and at the same time facilitating the recycling of water flow, being convenient for cleaning and installation, and improving the use efficiency.
[0004] When the existing CN219914008U is in use, it is beneficial to prevent the inner wall of the tail smoke chamber from forming crusts, increase the fluidity of air, and at the same time facilitate the recycling of water flow, being convenient for cleaning and installation, and improving the use efficiency. However, in actual use, only using the spraying method will cause inconvenience in cleaning the internal attachments, and it is necessary to spray multiple times to complete the internal cleaning. Only using a filter screen for filtration after spraying and cleaning will cause the pipeline to be blocked during the next extraction, so it still needs to be improved. Content of the Utility Model

After limiting, the second limiting block is installed on the lead screw by threads, enabling the operator to turn on the driving mechanism to drive the lead screw to rotate. According to the rotation direction of the lead screw, the scraper can be driven to move up and down, thereby scraping and cleaning the inner wall of the smoke chamber body with the scraper. When the crust is scraped and cleaned, it is sprayed simultaneously, and further, the smoke chamber is treated for the second time to avoid the formation of soot crust. Moreover, the flue gas can be discharged through the smoke outlet pipe and the exhaust pipe. BRIEF DESCRIPTION OF THE DRAWINGS
