Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: a waste gas treatment device for a burner comprises a burner 1 and a waste gas purifier 2, wherein an exhaust pipe of the burner 1 is communicated with a connecting pipe 3, one end of the connecting pipe 3, which is far away from the burner 1, is communicated with an air inlet pipe of the waste gas purifier 2, a first filter screen plate 4 is fixedly arranged in the connecting pipe 3, the bottom of the connecting pipe 3, which is positioned at one side of the first filter screen plate 4, which is close to the burner 1, is communicated with a collecting box 5, an air duct 11 is communicated with one side of the connecting pipe 3, which is positioned at one side of the first filter screen plate 4, which is far away from the burner 1, the other end of the air duct 11 is communicated with the collecting box 5, a second filter screen plate 12 is fixedly connected in the collecting box 5, which is positioned at the port of the air duct 11, the air duct 11 is used for circulating waste gas in the collecting box 5 and preventing impurities in the collecting box 5 from entering the connecting pipe 3 again, and a sealing cover 10 is connected at the bottom of the collecting box 5 by screw threads, can clear up the impurity in the collecting box 5 through opening sealed lid 10, the one side that just is located first filter plate 4 and is close to combustor 1 on the roof still rotates and is connected with threaded rod 6 in connecting pipe 3, the top fixed mounting of connecting pipe 3 has motor 9, motor 9 passes through the wire and is connected with external power source and control system, and motor 9's output passes through shaft coupling and threaded rod 6 and connects, and threaded rod 6 goes up threaded connection has and is used for carrying out the cleaning brush 7 of clearing up to first filter plate 4 surface, go back fixedly connected with and threaded rod 6 parallel arrangement on the roof and with cleaning brush 7 sliding connection's gag lever post 8 in connecting pipe 3, gag lever post 8 is used for preventing that cleaning brush 7 from following threaded rod 6 and rotating.
