Dust collection device

Abstract

The invention discloses a dust collection device. The dust collection device comprises an air suction cylinder provided with a supporting part, wherein an air guiding cylinder is arranged in the supporting part, an air outlet cylinder extending to the exterior of the air guiding cylinder is arranged in the air guiding cylinder, the air outlet cylinder and the air suction cylinder are communicated, and an airflow passage is formed between the air outlet cylinder and the air suction cylinder; an air cavity is arranged between the air guiding cylinder and the air outlet cylinder, and a first arc-shaped bending part extending towards the air cavity is arranged at the end part of the air outlet cylinder; a second arc-shaped bending part is arranged at the end part of the air guiding cylinder, the second arc-shaped bending part extends to the interior of the airflow passage and extends towards the air outlet end of the airflow passage, and a gap communicating with the air cavity and the airflow passage is arranged between the second arc-shaped bending part and the first arc-shaped bending part; a gas compressor communicating with the air cavity is further arranged on the air guiding cylinder. The operation of dust collection can be effectively completed, and the environment where the gas compressor is improved, the problem of impeller abrasion and corrosion cannot occur, and meanwhile the work efficiency and service life are guaranteed; the device is small in size, low in occupied space rate and convenient for installation and arrangement.

Description

technical field [0001] The invention relates to a dust suction device. Background technique [0002] At present, common road sweepers or other dust collection equipment generally use the drive of the centrifugal fan to carry out the dust collection work. Dust work; in the process of operation, the dust and water vapor in the air flow will enter the inside of the fan, which will cause wear and corrosion of the internal structure of the fan impeller, and at the same time, dust will accumulate on the surface of the impeller, destroying the dynamic balance of the impeller, resulting in The working efficiency and service life of the fan are greatly reduced. [0003] In addition, to complete the above-mentioned dust collection work, a fan with a large flow rate is required. The fan with a large flow rate has a large volume and takes up a large space, which will greatly increase the difficulty of assembly and layout.
