Thereby effectively reducing the accumulation and retention of the particulate matters in the suction cavity 11 and improving the discharge efficiency and speed of the particulate matters. If the guide inclined plane and the discharge hole are not provided, particles can stay in the suction cavity 11 for a long time, so that the pressure in the suction cavity 11 is increased, and the working effect and the service life of the cleaning device are affected.

The cleaning device can avoid accumulation and detention of particulate matters in the suction cavity 11, so that the pressure in the suction cavity 11 is increased, and the working effect and the service life of the cleaning device are affected. If the particulate matter accumulates and stays too much in the suction chamber 11, the pressure in the suction chamber 11 may be increased, affecting the operation efficiency and stability of the plurality of particulate matter suction fans 80, resulting in degradation of the performance of the cleaning device or malfunction. Through this cleaning device, can utilize the direction inclined plane and discharge hole to follow the discharge of inhaling material chamber 11 bottom to reduce the pressure in inhaling material chamber 11, guarantee the normal work and the life of a plurality of particulate matter suction fans 80.

Dust in the interior of the steel heating furnace may contain some harmful substances or heavy metal elements, which, if discharged into the environment, may cause adverse effects and harm to air quality, water resources, soil, vegetation, animals, humans, and the like.

The suction pipe 20 in this embodiment is a bendable pipe. The suction pipe 20 is a bendable pipe which can be adjusted and connected according to different shapes and positions inside the steel heating furnace, so that the steel heating furnace with different shapes and positions can be effectively adapted, and the applicability and flexibility of the cleaning device are improved. The bendable pipeline can be adjusted and connected according to different shapes and positions in the steel heating furnace, so that the steel heating furnace is effectively adapted to the steel heating furnace with different shapes and positions, and the applicability and flexibility of the cleaning device are improved. This is because the interior of the steel heating furnace may have different shapes and positions, such as circular, square, rectangular, oval, etc., as well as upper, middle, lower, side, etc., which have different requirements and difficulties for the connection and interaction of the cleaning devices. The cleaning device can be connected and interacted with any part in the steel heating furnace, so that the comprehensive cleaning of particulate matters and dust in the steel heating furnace is realized.
