Dust collector for rubber plant mixer

The selection of appropriate specifications of dust collectors and fans is crucial in the dust removal and ventilation design process of the rubber plant's internal mixer dust collector. It also determines the scale of investment and the cost of future use and maintenance. Our company has relevant technical personnel to design and produce ventilation and dust removal systems for many rubber factories, which have good dust removal effects, reasonable structures, and low operation and maintenance costs. The three prevention (,,) dust removal bags are widely used in the carbon black dust removal industry. The dust collector of the rubber plant's internal mixer mainly includes: bag dust collector of the feeding device after the internal mixer, carbon black bag dust collector, and tank dust collector.

Design standard for dust collector and suction hood of rubber plant mixer:

(1) The dust collector hood should be as close to the pollution source as possible without affecting the operation and maintenance of the mixer. When considering installation and maintenance conditions, a fully enclosed structure should be adopted to reduce the dust removal air volume. If it is not allowed to use a fully enclosed structure, it can be considered to add a soft barrier edge enclosed structure.

(2) The dust collector hood of the rubber plant mixer should be fixed with a wind deflector in the middle of the hood opening as much as possible, without affecting installation and maintenance. Ventilation openings should be left around the hood outlet to reduce the cross-sectional area of the hood, increase wind speed or reduce air volume. Under the premise of constant wind speed, the percentage reduction in area is equal to the percentage reduction in air volume.

(3) Due to the presence of plastic bags, paper bags, or small rubber beans at the feeding ports of the unpacking machine, internal mixer, and small material feeding ports, if the air flow is too high, it is easy to suck the plastic bags or paper bags into the dust collector and attach them to the filter bag. It is difficult to remove them by using reverse blowing, which affects the dust removal effect. If entering the ash discharge screw or rotating ash discharge valve, these debris are likely to entangle on the screw or ash discharge valve blades, or even squeeze into the gap of the screw or ash discharge valve, causing malfunctions (which may occur during user use). Therefore, it is required to add steel plate mesh to the wind hoods in these areas, with a mesh diameter of about 8-10mm.

(4) Different specifications of suction hoods and dust collectors can be designed according to the on-site installation conditions of the user. The cross-sectional wind speed of the wind hood is generally set at 0.5-1.0m/s, and the maximum value is taken when the wind hood is far from the pollution source. If the wind hood is too far away from the pollution source due to installation reasons, the cross-sectional wind speed can be increased to around 2m/s.
