Structure Characteristics Of Closed Cover Of Dust Removal Equipment

Structure characteristics of closed cover of dust removal equipment
Dust removal equipment closed cover is all the pollution sources to block up, so that the spread of harmful substances is limited in a small confined space, and with enough exhaust disk to produce negative pressure in the cover, in order to ensure that harmful substances do not escape from some holes and gaps. Some equipment itself closed, only according to the requirements of the exhaust pipe can be connected, such as drum screen, cleaning roll Jane.
According to the installation form, the closed cover is divided into fixed and mobile two kinds, such as the closed cover of the old sand belt conveyor is fixed, and the closed cover of the large sand dropping machine is mobile.
According to the degree of sealing, sealing cover is divided into local sealing cover, integral sealing cover, large volume closed room three.
Part of the closed cover is to partially close the dust point of the equipment, and the process equipment is exposed outside the closed cover. Such as belt conveyor blanking point. The volume of the local sealing cover is small, which is suitable for the dust source with small dust production airflow speed, and small concentrated and continuous dust and instantaneous supercharging.
The overall closed cover is to produce dust equipment or most of the location closed up, only the transmission part of the equipment in the cover, such as rolling screen overall closed cover is suitable for large mechanical vibration, dust area and dust production airflow speed of the dust source.
Large volume closed chamber is to produce dust equipment or location all closed up, such as vibrating screen closed chamber. Closed chamber volume is large, can buffer dust air flow, reduce local positive pressure. It is suitable for the equipment with many dust points, large dust area and dust producing air velocity, and frequent maintenance or regular replacement of parts.
