Description

Technical Field

[0001] This invention relates to the field of kiln exhaust gas treatment technology, and in particular to an industrial kiln exhaust gas treatment device. Background Technology

[0002] A kiln is a device used to fire ceramics, glass, metals, and other materials. It is typically constructed from materials such as brick, clay, or metal, and possesses high-temperature resistance and fire resistance. A kiln provides a high-temperature environment, allowing raw materials to undergo processes such as heating, melting, and crystallization within the furnace, thereby completing the production of the product. There are various types of kilns, such as ceramic kilns, glass kilns, and metal smelting furnaces, each differing in structure and working principle.

[0003] Specifically, a kiln flue gas treatment device, such as CN219023722U, washes the exhaust gas by spraying it, thereby increasing the washing effect and efficiency. However, during the flue gas treatment process, particles in the flue gas mix with water and flow downwards along the inner wall of the tank. Over time, this accumulates deposits on the inner wall of the tank, reducing its volume and making it difficult to clean later. Summary of the Invention

The scraper is provided with rectangular notches corresponding to the air intake mechanism and the spraying mechanism. The strip plate is provided with bristles abutting against the inner wall of the tank body. A sliding groove is also provided around the outer wall of each annular seat. Multiple sets of bolts I are screwed onto the side wall of the tank body, with their ends extending into the sliding groove. A motor is also provided at the top of the tank body. A gear is provided on the output shaft of the motor, located in the upper annular seat. Gear teeth that mesh with the gear are axially arranged on the inner wall of the upper annular seat.

[0008] Preferably, the air intake mechanism includes an air intake pipe located outside the tank body, and a branch pipe extending into the tank body is provided on the air intake pipe, the branch pipe being correspondingly provided with one of a set of rectangular notches.

[0009] Preferably, the spraying mechanism includes a spray pipe located outside the tank body, and the spray pipe is provided with nozzles extending into the tank body, the nozzles being correspondingly arranged with one of the sets of rectangular notches.

[0018] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0019] An industrial kiln exhaust gas treatment device includes a tank body 1, with an exhaust pipe and a drain pipe respectively installed at the upper and lower ends of the tank body 1. An air intake mechanism 2 and a spray mechanism 3 located on the upper and lower sides of the air intake mechanism 2 are installed on the tank body 1. A cleaning mechanism 4 is also installed inside the tank body 1.

[0020] The cleaning mechanism 4 includes annular seats 41 located on the upper and lower sides inside the tank body 1. Two sets of spraying mechanisms 3 are located between the upper and lower sets of annular seats 41. A strip plate 43 and a scraper 42 abutting against the inner wall of the tank body 1 are provided between the two sets of annular seats 41. The scraper 42 is provided with rectangular notches 44 corresponding to the air intake mechanism 2 and the spraying mechanism 3. The strip plate 43 is provided with bristles 45 abutting against the inner wall of the tank body 1. A ring of sliding grooves 46 is also provided around the outer wall of the annular seats 41. Multiple sets of bolts I47 extending into the sliding grooves 46 are screwed onto the side wall of the tank body 1. A motor 48 is also provided at the top of the tank body 1. A gear 49 located in the upper annular seat 41 is provided on the output shaft of the motor 48. Gear teeth 410 that mesh with the gear 49 are axially provided on the inner wall of the upper annular seat 41.

[0021] The air intake mechanism 2 includes an air intake pipe 21 located outside the tank body 1, and a branch pipe 22 extending into the tank body 1 is provided on the air intake pipe 21. The branch pipe 22 is correspondingly arranged with one of the sets of rectangular notches 44. Figure 1 As shown, several branch pipes 22 are located inside the rectangular notch 44 in the middle. When the annular seat 41 drives the rectangular notch 44 on the scraper 42 to rotate, the rectangular notch 44 in the middle will slide on the branch pipe 22. At this time, the branch pipe 22 will not contact the side wall of the rectangular notch 44 in the middle and thus affect the rotation of the scraper 42.

[0022] The spraying mechanism 3 includes a spray pipe 31 located outside the tank body 1, and a nozzle 32 extending into the tank body 1 is provided on the spray pipe 31. The nozzle 32 is correspondingly arranged with one of the sets of rectangular notches 44. Figure 1 As shown, when the annular seat 41 drives the rectangular notch 44 on the scraper 42 to rotate, the rectangular notches 44 on the upper and lower sides will slide on the corresponding nozzles 32. At this time, the nozzles 32 will not contact the sidewalls of the corresponding rectangular notches 44 on the upper and lower sides, thus not affecting the rotation of the scraper 42.

[0023] In this embodiment, the outer wall of the annular seat 41 is provided with protrusions 5 located on both sides of the corresponding scraper 42 and strip plate 43, and the protrusions 5 are provided with bolts II6 for locking and fixing the corresponding scraper 42 and strip plate 43.

[0024] The tank body 1 has a screw hole on its side wall that is screwed to the bolt I47 rod. The end surface of the bolt I47 rod is smooth and extends into the corresponding groove 46.

[0025] The present invention suspends the annular seat 41 in the tank body 1 by extending the end of bolt I47 into the groove 46, thereby indirectly suspending the scraper 42 and the strip plate 43 in the tank body 1. At the same time, the two ends of the scraper 42 and the strip plate 43 are locked and fixed to the protrusion 5 by bolt II6, so that the strip plate 43 and the scraper 42 are movably connected to the annular seat 41, and the annular seat 41 is movably fixed in the tank body 1, making it easy to install and disassemble the above components. In the above process, the end of bolt I47 extends into the groove 46 and abuts against its side wall, thereby positioning the annular seat 41 from multiple directions and preventing the annular seat 41 from horizontally displacing in the tank body 1.

[0026] The method of using this invention is as follows: the flue gas is drawn into the tank 1 through the inlet pipe 21 and the branch pipe 22 by the fan and the pipeline. At this time, the spray liquid is injected into the spray pipe 31 by the pump and the pipeline and sprayed out by the nozzle 32, thereby performing spray washing work on the flue gas.

[0027] When the inner wall of the tank 1 needs to be cleaned, the motor 48 drives the upper annular seat 41 to rotate through the gear 49 and gear teeth 410. The upper annular seat 41 will cause the sliding groove 46 on its outer wall to slide on the end of the bolt I47 rod. At this time, the upper annular seat 41 will drive the lower annular seat 41 to rotate together through the scraper 42 and the strip plate 43. The rotating scraper 42 will scrape and clean the inner wall of the tank 1, while the rotating strip plate 43 can clean the inner wall of the tank 1 again through the brush bristles 45. During the above process, when the scraper 42 rotates, it will cause the rectangular notch 44 to slide over the corresponding nozzle 32 and branch pipe 22, preventing the nozzle 32 and branch pipe 22 from contacting the scraper 42 or the side wall of the rectangular notch 44 and affecting the rotation of the scraper 42.

[0028] The present invention has been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
