Dust removing box and dust removing system with same

Abstract

The invention relates to a dust removing box and a dust removing system with the same, which are used for filtering dusty air flow. The dust removing box comprises a box body and an air filtering barrel arranged in the box body, wherein the box body is provided with an air exhaust and an air inlet; the dusty air flow enters the box body from the air inlet, is filtered by the air filtering barrel and is discharged from the air exhaust; the air inlet is close to the top of the air filtering barrel; the top of the air filtering barrel is communicated with the air inlet; and the bottom of the air filtering barrel is closed. In the dust removing box and the dust removing system with the same, an upper inlet and upper exhaust dust removing mode is adopted, so that the phenomenon that dust which has been filtered off by the air filtering barrel is continuously remixed in the dusty air flow when the continuous dusty air flow rushes into and floods the box body from the lower side of the dust removing box is avoided.

Description

technical field [0001] The present invention relates to a dust removal system, and in particular to a dust removal box for filtering dust-laden airflow and a dust removal system with the dust removal box. Background technique [0002] At present, domestic dry dust removal road sweepers generally use dust removal boxes to filter and remove dust from the dusty airflow. Although some manufacturers use cloth bags or plate filters as filter bodies, there are defects such as low dust removal efficiency and easy bag sticking during use. Therefore, there are fewer and fewer products that use bag or plate filters as dry dust removal, and more dry dust removal road sweepers use the dust removal mode of the dust removal box. [0003] The existing dust removal box, no matter it is equipped with three air filter cartridges or four air filter cartridges, the dust removal box is divided into upper and lower parts. The lower part of the box is provided with an air inlet for the dust-laden ...

AI Technical Summary

Problems solved by technology

However, there are deficiencies in this method of air intake and dust removal from the bottom to the top. A steady stream of dust-laden airflow pours in from the bottom of the dust removal box and fills the inside of the box. The ash removal device is affected by the high-speed dust-laden airflow from the lower part of the box, and the removed dust cannot smoothly fall into the ash collecting hopper at the lower part of the box.

Although the dusty airflow is continuously filtered by the air filter, the dust remains on the outer wall of the air filter, and finally is removed from the wall of the air filter by the pulse cleaning device, but most of the dust is continuously re-stirred into the dusty airflow , so that the dust concentration in the dusty airflow on the upper part of the filter cartridge is always kept at a high level, the filter dust removal efficiency of the filter cartridge is not ideal, which reduces the efficiency of dry filter dust removal
