Abstract

The invention relates to the technical field of exhaust pipes, and discloses an exhaust pipe capable of preventing tuyere blockage and having automatic replacing and warning functions. The exhaust pipe comprises a shell, wherein a conversion groove is formed in the top of the shell, filter screens are movably connected to the two sides of the conversion groove, starting grooves are formed in the left side of the shell, and a starting block is movably connected to the top of each starting groove; and a rotating block is movably connected to the bottom of each starting groove, and an electric contact is fixedly connected to the outer side of each rotating block. According to the exhaust pipe capable of preventing tuyere blockage and having the automatic replacing and warning functions, through cooperation of the starting blocks and the rotating blocks, when the filter screens fail due to blockage, an electromagnet circuit is switched on, electromagnets and a permanent magnet interact to drive a clamping key to move, the locking state of the failed filter screens is released, meanwhile, the failed filter screens move downwards under the action of gravity of a balancing weight, and standby filter screens are driven to enter a working position through interaction with a transmission group, so that automatic replacement of the filter screens is realized, the exhaust efficiency of the exhaust pipe is prevented from being influenced by blockage of the filter screens, and dust concentration is prevented from rising.

Description

technical field [0001] The invention relates to the technical field of exhaust pipes, in particular to an exhaust pipe that prevents tuyere from being blocked and automatically replaces and warns. Background technique [0002] In some processing and production workshops that are prone to dust, such as flour production workshops and lime powder production workshops, the processed products are easy to float in the air, which increases the dust concentration in the air, which is not conducive to long-term work and production of workers and causes health problems. At the same time, when the dust concentration exceeds the safe range, it is easy to encounter an open flame explosion, which greatly increases the risk of production, so ventilation equipment is indispensable, and ventilation equipment can greatly reduce the dust concentration in the workshop. [0003] However, in the normal production and use process, since the exhausted gas carries a large amount of dust, it is neces...
