  • Patent number: 10806317
    Abstract: A surface cleaning apparatus has a first air flow path extending from a dirty air inlet to a clean air outlet with a suction motor and a cyclone positioned in the first air flow path. The cyclone has a cyclone chamber, a first airflow passage, and a second airflow passage. The first airflow passage defines a first tangential air inlet to the cyclone chamber and the second airflow passage defines a second tangential air inlet to the cyclone chamber. The airflow path includes a common airflow passage upstream of the first and second airflow passages and an axis of the common airflow passage intersects the cyclone chamber. At least a portion of the first tangential air inlet is positioned upstream from a location at which the common airflow passage axis intersects the cyclone chamber.

  • Patent number: 10807030
    Abstract: The present invention provides a blade group for demisting and dedusting, comprising a plurality of blades that are annularly arranged and a support mechanism for fixing the blades; wherein the blade comprises a section of curved plate, a cross section of the curved plate being a gradually-varied arc curve whose curvature increases progressively along an airflow direction. When gas carrying fine mist droplets or fine dust particles are passing through the blade group for demisting and dedusting, since the gas is different from the mist droplets or dust particles in terms of mass, separation of the gas from the liquid or dust under the effect of inertia is promoted. Especially, the gradually-varied blade curve enables the droplets or dusts to be captured and removed efficiently under the effect of a constantly-varied inertia and a drag force, which remarkably improves the working efficiency in combination with a washing device.

  • Patent number: 10801500
    Abstract: A separation tank useful to separate a compressed gas from a byproduct of compression (such as a lubricant/coolant used in the compression process) can include one or more baffles. The baffles used in the separation tank can include a number of passages to permit a flow of compressed gas to pass. The passages can include a louver to assists in directing the flow and/or assist in further separation of the compressed gas from the lubricant/coolant. The louvers can appear on one side of the baffle, and in one form are located solely on the downstream side of the baffle. The baffle can include a relief for liquid leveling within the tank. Any number of approaches can be used to make the baffle, including cutting and/or stamping.

  • Patent number: 10758853
    Abstract: Process and apparatus capable to remove particles from a fluid stream (such as air or water) and directly convert the removed particles into a solid compact format commonly known as briquettes in a standalone combined single unit operation. The outlined process and equipment operates without the need for rotary valve technology and uses air versus hydraulics offering a cost competitive equipment solution for the end user. Active processes within the apparatus actively control the dust thereby allowing a variety of particles to be processes irrespective of moisture content and surface adhesive characteristics. Having the low-cost capability to convert explosive air/dust mixtures into briquettes significantly enhances safety and also reduces the associated manhandling effort required with disposing of collected dust with many briquettes typically having 100-500× the density of the incoming particles.
