A jet dust collector is a type of industrial dust collectors, which is used to collect the dust or the chips that are produced by the wood working fields, and send the clean air back to the working environments.
The jet dust collector works following the principle that separates the chips from the airflow, collecting the chips in the drum, and delivers the filtered air out, in order to keep the working environments clean and free from the damages that are caused because of the dust.
In the wood working fields, no matter small or large scale, when the workpieces that are made of wood are machined, such as being drilled to make holes, milled to create slots, or ground to remove chips, to name a few, the dust, or so-called chips would be produced.
Those chips are the particles that are produced when the cutting tools and the workpieces come in contact with each other, and they can be either visible, or invisible, which are expressed in microns.
Even if there are visible chips, they take the operators time and efforts to cleam up the working environments. As for the invisible ones, it is hard to tell if they are all cleaned up.
Therefore, there are more and more industrial fields, which produce wood products, adopt the jet dust collectors in their workspaces, which makes it easier and more convenience to efficiently remove both the visible chips and the invisible particles that might be filled in the air.
There are two main types of jet dust collector, which is divided based on the variation in the filtration process, including the single stage dust collectors and the 2-stage cyclone dust collectors.
● single stage dust collectors
This type is the original form of the dust collector, which consists of a collection bag, a vortex cone, a canister filter, a motor, and two dust ports.
The collection bag is used to collect the larger particles of the chips, which allows the operator to discard those chips by simply replacing the bags instead of sweeping those chips by the manual force.
In addition, there are several swivel casters that are mounted under the entire device, which enhances the mobility of the jet dust collector when it is necessary to be moved from one site to another.
The vortex cone is set upon the collection drum, which is used to receive the chips from a connecting hose between the motor and the cortex cone, and separate the smaller particles from the chips.
The canister filter is arranged on top of the vortex cone, and is used to conduct the filtration of the smaller particles, which can be least to 2-micron particles, and send the filtrated air out to the atmosphere.
The motor is beside the set of the above three components, which is connected to the vortex cone with a hose on one side, and the other is attached to the two dust ports. It provides the energy to the fan that blows the chips up to the filtration site.
As for the two dust ports, they can be connected to the working machines with one hose respectively, so as to instantly receive the chips from the working sites, and prevent those chips from flowing through the air.
● 2-stage cyclone dust collectors
The basic configuration of the 2-stage cyclone dust collector is similar to the former type. However, the collection bag is transformed into a drum, which provides more collecting capacity of the chips.
In addition, the collection drum is separated from the 2-stage cyclone dust collector by the casters, which makes it easier to maneuver when the bag inside the drum requires to be replaced.
Besides, there are one more dust port than the single stage dust collector, which are mounted beside the larger motor with bigger horsepower.
Furthermore, there is an additional direct mounted filter beside the first filter on the top, which makes up the 2 stages of filtration processes, and assists to perform better for the even smaller particles than the single stage type.
● chip suction
The first step in the operation of a jet dust collector is the chip suction, which is assisted by the dust ports, the motor, and the hoses that connect these components.
When the machines are working, the chips produced would be sucked thourgh the hoses and transferred to the dust ports, and the motor blows the chips up with the fan.
● particle separation
Next, the chips would be blown through the cortex cone. The cortex cone would separate the larger and smaller particles, drop the larger particles into the collection bag or drum, and allow the smaller ones continue to be blown up to the canister filter.
● air filtration
Finally, the smaller particles of the chips would undergo the filtration processes. For the single stage dust collector, they would be cleaned by the one and only canister filter, while the particles of the 2-stage cyclone dust collector would be delivered to the direct mounted filter afterwards.
Once the air that contains particles are filtrated after passing through the filters, the purified air would be sent back to the atmosphere of the working environments.
