A water filter is provided. The water filter includes a filtration material and a filter housing spaced for accommodating at least a portion of the filtration material therein. The water filter also includes a housing cap coupled to an upper end of the filter housing for enclosing the filtration material within the water filter. The housing cap includes an upper portion, a lower portion, and a channel formed through the upper portion and the lower portion. The water filter also includes an interface adapter accommodated in the channel, wherein the interface adapter includes a side wall vertically extending from an upper surface of the interface adapter and partially around a perimeter of the upper surface, and a projection vertically extending from the upper surface, wherein the projection is integrally formed with the upper surface and a portion of the side wall.

Disclosed is high-ash fine coal slime separation equipment and method, applicable to the field of coal washing. The high-ash fine coal slime separation equipment includes a feeding system (1), a mineralization system (2), a separation system (3) and a pulsating water flow control system (4). A coal slime mineralization region is isolated from a separation region; and a damping block and a pulsating water flow device are arranged in a mineral separation system. A flotation feeding is fed into the feeding system (1), slurry mixing operation is completed, coal slime enters the mineralization system after pulp mixing to generate turbulent collision to form mineralized bubbles, the mineralized bubbles enters the separation system (3) after passing through a turbulent-flow dissipation pipe (12), and meanwhile, pulsating water flow with a certain frequency and waveform is fed into the separation system (3) by the pulsating water flow control system (4).

A compact hydraulic particle separator apparatus is disclosed. The disclosed apparatus comprises an upper chamber and a lower chamber separated by a partition. A liquid fluid flow upwelling through the partition from the lower chamber is caused to mix with tangential jet of fluid flowing introduced above the partition in the upper chamber produces an upwardly-flowing cyclonic flow within the upper chamber. Particle mixtures containing low- and high-density particles and other solids are introduced into the upper chamber through a feed tube having a mouth that is offset from the center of the upper chamber. Low-density particles are immediately entrained in the cyclonic flow and swept upward and exit the apparatus.

An eco-friendly water filtration apparatus. The apparatus may comprise a lid comprising openings that allow water to flow into the apparatus, and an enclosure that is open at one end and comprises openings at the opposing end that allow water to flow out of the apparatus. The enclosure may be configured to receive a pod of activated carbon, while allowing removal of the pod, and the lid may be configured to attach to and detach from the enclosure at the enclosure's open end.

A magnetic debris level measuring device for a magnetic filter is disclosed. The magnetic debris level measuring device includes a magnetometer and a temperature sensor. The temperature measured by the temperature sensor is used to calculate a corrected magnetometer reading, which in turn can be used to determine the amount of captured magnetic debris held within the filter. The device has a stored threshold for the corrected magnetometer reading, and when the corrected magnetometer reading crosses the stored threshold a notification is issued that the filter is full. If it is detected that debris continues to be captured after the full notification has been issued, the stored threshold will be updated accordingly.

An oily smoke purification device includes a holder, a main housing, a mixing mechanism, a filter and an exhaust fan. The holder is filled with purification solution, the exhaust fan is started to cause a negative pressure inside the main housing, oily smoke enters the purification solution from a gap between the holder and the main housing and is mixed with the purification solution under an action of the mixing mechanism to absorb dirt in the oily smoke into the purification solution, and the oily smoke is filtered by the filter to generate clean air which is sucked by the exhaust fan. The hazardous substance including oil, dust and other impurities in the contaminated air is filtered and the air is purified, thereby protecting the environments and ensuring the heath of people.

A beauty water generator with a high performance filtering function includes a housing portion used as a body of the beauty water generator; a mounting portion provided inside the housing portion; and a filter unit having a first filter part that purifies introduced raw water through bottom-up movement and discharges purified water and a second filter part that, when the purified water is introduced therein, imparts functionality to the purified water through bottom-up movement and discharges beauty water, and provided inside the housing portion such that the first filter part and the second filter part are mounted and removed by rotating through the mounting portion.

An apparatus for dealcoholizing alcoholic beverage comprising: a first receptacle comprising means to receive alcoholic beverage, a second receptacle comprising means receive in fluid, a third receptacle arranged to receive alcoholic beverage from the first receptacle, said third receptacle being further connected to the second receptacle, means for producing vacuum at least functionally connected to at least the third receptacle to lower pressure therein, fractionating means at least partially inside the second receptacle, the fractionating means functionally connecting the second and third receptacle, wherein the apparatus is arranged to facilitate vacuum distillation for the alcoholic beverage so that vaporizing ethanol from the alcoholic beverage travels via the fractionating means to the second so that the vaporized ethanol is dissolved with the fluid in the second receptacle. Corresponding method for dealcoholization is presented.

An open loop cooling apparatus is provided. The open loop cooling apparatus includes gas capturing and collecting elements, an expansion valve receptive of pressurized gas from the gas capturing and collecting elements and configured to expand the pressurized gas, an evaporator coil downstream from the expansion valve through which the pressurized gas, having been expanded in the expansion valve, passes to cool air flowing over the evaporator coil and one or more storage tanks receptive of the pressurized gas from the evaporator coil for later sale.

A magnetic filter 10 includes first and second separation chambers 10, 12. The separation chambers 10, 12 each have an inlet and an outlet, and the separation chambers 10, 12 are joined together such that the inlets of the first and second chambers are adjacent, and the outlets of the first and second chambers are adjacent. An inlet port arrangement 28 connects both inlets to a single inlet pipe, and an outlet port arrangement 30 connects both outlets to a single outlet pipe.
