Air purifier for home kitchen

The invention provides an air purifier for a home kitchen. The air purifier comprises a shell with an air inlet in the front end and an air outlet in the rear end. A filtering channel is formed in the shell. A draught fan is arranged in the filtering channel. The air purifier is characterized in that a former filtering device for filtering out large-grain-size particles and a later filtering device for filtering out small-grain-size particles are arranged in the filtering channel, and a rotary filter screen for blocking and filtering out oily particles is arranged in the filtering channel. The air purifier has the beneficial effects that the air purifier for the home kitchen is designed for the air environment of the home kitchen, and the air purifier can keep working normally under the condition that lampblack is sucked continuously; the residual lampblack, burnt gas and peculiar smell in kitchen air can be effectively removed, viruses and bacteria in the air are killed, and therefore the air quality of the home kitchen is remarkably improved; and the lampblack particles are removed in a classified manner from the coarse particles to the fine particles, the service life of all the parts is greatly prolonged, and the requirements for the purification performance are met after all the parts are integrated.

Sprayer and media cartridge therefor

The subject invention relates to a power sprayer that can be conveniently used by both professionals and amateurs. This power sprayer offers flexibility of movement because it can be battery operated. It also is designed to eliminate the need for cleaning its spray nozzle after being used. The media being sprayed can also be easily changed quickly. For instance, paint colors can be changed quickly and repeatedly by simply changing the media cartridges that are adapted for simple attachment to the sprayer. The media cartridges used in conjunction with the sprayers of this invention can also eliminate the inconvenience associated with refilling conventional power sprayers with a desired media. The present invention more specifically discloses a media cartridge system for a sprayer comprising: (a) a media container, (b) a self-cleaning nozzle, (c) a media shut-off means, (d) a primary media atomizing aperture in a configuration relative to the self-cleaning nozzle, (e) a movable media containment member within the media container, (f) a gas transfer interface, and (g) a power unit engagement means. The subject invention further discloses a sprayer which is comprised of (1) an electrical power source, (2) an electric motor, (3) a pump which is driven by the motor, (4) an output, (5) an electrical control switch, (6) a media cartridge air transfer interface, (7) a media cartridge engagement means, and (8) a media cartridge system which is comprised of (a) a media container, (b) a self-cleaning nozzle, (c) a media shut-off means, (d) a primary media atomizing aperture in a configuration relative to the self-cleaning nozzle, (e) a movable media containment member within the media container, (f) a gas transfer interface, and (g) a power unit engagement means. The present invention also reveals a sprayer which is comprised of (1) a power unit which includes (a) an electrical power source, (b) an electric motor, (c) a pump which is driven by the motor, (d) an output control, and (e) an electrical control switch, (2) a nozzle unit which includes (a) a media cartridge air transfer interface, (b) a power unit engagement means, (c) a gas transfer interface, and (3) a media container wherein the media container includes (a) a media cartridge engagement means, (b) a movable media containment member within the media container, (c) a media container air transfer interface and (d) a media supply line interface.

Construction method of asphalt pavement pit slot repairing vehicle based on electromagnetic heating

The invention discloses a construction method of an asphalt pavement pit slot repairing vehicle based on electromagnetic heating. The construction method comprises the following steps: detecting a pavement pit slot; starting the bituminous pavement pit slot repairing vehicle to move on the pavement, and scanning the road condition of the pavement by a pavement scanner at the front part of the vehicle body; preheating the pavement; processing, and adding a repairing material and flattening; the asphalt pit slot repairing capsule in the storage bin is discharged from a discharge port, the material falls into a stirring container in the repairing mechanical arm structure, then the material is subjected to induction heating through an induction coil wound on the stirring container, and then the position of the preheated pit slot is inducted through a temperature inductor to be filled and flattened; vibrating and compacting; cleaning and acceptance. The asphalt pavement pit slot repairing vehicle based on electromagnetic heating is combined with the pit slot repairing capsule to conduct electromagnetic induction repairing on the pit slot in the asphalt concrete pavement, and rapid repairing of the asphalt concrete pavement is achieved.

Chromium-base catalyst for synthesizing alpha-tetralone by tetrahydronaphthalene and preparation method thereof

The invention discloses a chromium-base catalyst for synthesizing alpha-tetralone by tetrahydronaphthalene and a preparation method of the chromium-base catalyst, belonging to the technical field of catalyst preparation. The catalyst provided by the invention adopts activated aluminium oxide as carrier; Cr oxide is used as main active component of the chromium-base catalyst; the mass percentage of the main active component is 2.0-4.0%; the oxide of any one of Co, Mn, Cu, Ni, Fe, Zr and Ce is used as auxiliary active component of the chromium-base catalyst; the mass percentage of the auxiliary active component is 0.5-3.5%. The chromium-base catalyst is prepared by the co-dipping method. The chromium-base catalyst has the advantages of low cost, catalytic activity, excellent selectivity and environment friendliness. For example, when the conversion rate of the tetrahydronaphthalene is 48.2% during the catalytic oxidization reaction on the conditions of 120 DEG C of temperature, 8 hours of reaction time and normal pressure, the selectivity of the alpha-tetralone and alpha-tetralol is 84.6% and 11.9% respectively; and the catalytic performance of the catalyst is not changed essentially after circular reaction for four times.
