FIELD OF THE INVENTION
The dust control device was conceived to provide a way to protect workers and others in the area where work is being performed, from the suspended particles in the atmosphere, while mixing products together. This dust control device will help many different workers in the world by providing a product that will give them an additional protection from the ill effects of airborne hazards.
BACKGROUND OF THE INVENTION
Workers often need to mix products in buckets or containers. The resulting process can put the person at risk of airborne particles. The inventor was pondering this idea, and started thinking about different ways to control the dust. Workers were trying to set a vacuum hose near the edge of the bucket but this did not effectively control the dust. The inventor drew up his idea and experimented with a prototype and proved his theory that by creating a venturi while isolating the vacuum attachment point, the worker was able to effectively control the airborne dust.
SUMMARY AND OBJECT OF THE INVENTION
Referring to FIG. 1, the dust control device 10 is fitted to set on top of a container C to be used for mixing, and a vacuum hose V is attached at an attachment point 14 of the dust control device. Once the vacuum V is properly fitted and turned on, the worker adds the mixtures to the container through the top of the dust control device 10, and then proceeds to mix the contents with a mixing tool, like a paddle bit and drill motor or trowel. When the proper mixture is attained, and the worker confirms the airborne contaminants have been removed, the worker pulls the dust control device 10 off the container C and is able to install their mixture.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 shows the dust control device 10 sitting on a container C, such as a 3 or 5 gallon bucket, and a shop vacuum hose H attached to the outlet port 14 of the dust control device 10. It also shows a typical shop vacuum V.
FIG. 2 shows a cross sectional view from the side of the dust control device 10 having an inlet funnel 20, the outlet port 14 with the 2 stage 1¾″ and 2¼″ connection point for the vacuum hose H. The base 24 of the dust control device 10 is designed to rest on top of a bucket or container C.
FIG. 3 shows a side perspective view of the dust control device 10 with the inlet funnel 20, the bottom of the inlet funnel 30, the bucket interface groove 34 and the outlet channel 40, which leads to the outlet port 14.
DETAILED DESCRIPTION OF THE PRESENT INVENTION
Referring to FIG. 1, the dust control device 10 consists of a funnel shaped opening or inlet funnel 30 in the top of the dust control device, where the product is poured into. As the product enters this opening, the narrowing of the opening causes both the material and the air to increase in speed. The interior develops a low pressure zone by attachment of a shop vacuum, which is attached at the outlet port 14 of the dust control device 10 via the vacuum cleaner hose H. The dust control device 10 is placed on the mixing container C, usually a 3, 5 or 7 gallon bucket. The bucket interface groove 34 makes contact with the container C and the static pressure of the dust control device 10 resting on the container C is sufficient to seal them when the vacuum is applied. The worker can pour the material, add mixtures, and water or other required liquid into the inlet funnel 30. They next will typically use a paddle bit and drill motor to mix the materials in the low pressure zone of the interior of the container C through the inlet funnel 30. Once the desired consistency is achieved, the dust control device 10 can be lifted off of the container C and the material can be safely used.
FIG. 2 shows a cross sectional view from the side of the dust control device 10. The inlet funnel 30 where material and the mixing tool will be introduced into the container C.
The outlet channel 40 leads to the outlet port 14 with the two stage connection point to accommodate either 1¾″ or 2¼″ vacuum hoses. The interface groove 34 of the dust control device 10 is designed to rest on top of a container C.
FIG. 3 shows a side perspective view of the dust control device 10 with the inlet funnel 20, the bottom of the inlet funnel 30, the bucket interface groove 34 and the outlet channel 40, which leads to the outlet port 14.
