A wastewater aeration system that can be pivoted upwardly to expose the treatment basin floor for removal of accumulated grit or other solids. The aeration system includes a blower and a rigid or flexible supply conduit extending into the basin to supply lateral pipes with air. The laterals normally extend horizontally along the basin floor and carry air diffusers which discharge air into the basin. A winch and cable system or other mechanism can be operated to pivot the lateral pipes and diffusers upwardly away from the basin floor so that they are out of the way of equipment used to remove grit from the floor. A vertical track may be provided along a wall of the basin to accommodate raising of the lateral pipes and diffusers out of the basin.

A gas is generated from a printing plate by exposure of the printing plate. A gas diffusing suction unit jets air from air jet ports to diffuse the gas generated from the printing plate by irradiation of laser light. The gas diffused by the air is sucked along with the air from a gas suction opening of the gas diffusing suction unit. At this time, a gas suction velocity is set to 1.2 or more times an air jet velocity to suck the gas / air efficiently. The gas / air may be sucked efficiently by setting a volume of suction to 30 or more times a volume of air jet.

The invention discloses an air guide plate component for an air conditioner and the air conditioner. The air guide plate component comprises a shell, an air guide plate and at least one set of air dispersion components, wherein an air outlet is formed in the shell; the air guide plate is pivoted in the air outlet, and is provided with at least one mounting port; the air dispersion components are arranged in the mounting ports to disperse and flow air blown out from the air outlet; and the at least one air dispersion component includes multiple layers of air dispersion bodies arranged in the air outlet direction of the air outlet side by side. According to the air conditioner, as the air dispersion components with multiple layers of air dispersion bodies are arranged on the air guide plate, the air passing through the air dispersion components can be dispersed by multiple times, and can flow in a dispersion mode to prevent direct blowing-out from the air outlet in the same direction, the no-air feel effect of the air conditioner can be realized, and the use comfort of the air conditioner is improved.

The invention belongs to the field of aquaculture and particularly discloses an ocean fishing wild swimming crab sand pit fattening breeding method. The method includes the steps that a temporary rearing pond is prepared; sand is laid in the temporary rearing pond and water is injected into the temporary rearing pond; crab varieties are selected; feeding is conducted twice a day, wherein the death rate and the disability rate can be reduced by selecting female crabs captured from a sea area crab cage, and the female crabs obtained after molting and mating can achieve high-density rearing; air which is introduced in a dispersed mode increases the dissolved oxygen content so as to satisfy the aerobic characteristic of wild swimming crabs and enhances the sea water turbulence degree to inhibit water quality deterioration; a circulating water pipeline accelerates sea water update and flowing, inhibits water quality deterioration and promotes air dispersion; a water filter can effectively remove pollutants like organic matter in seawater, pathogenic organisms like bacteria are killed, and diseases are reduced; residual bait and injured and diseased crabs in the temporary rearing pond are picked after two times of drainage every day, and water quality deterioration and disease spreading are inhibited. In a word, the disease rate and death rate of the swimming crabs are reduced, fattening growth and quality of the wild swimming crabs are promoted, and economic benefits are improved.

The invention discloses a flotation machine impeller for increasing the width of a conveying area. The flotation machine impeller comprises a circular cover plate. The upper portion of the circular cover plate is provided with an upper blade and an upper air dispersing device. The lower portion of the circular cover plate is provided with a lower blade and a lower air dispersing device. An inner air channel hole is formed in the middle of the circular cover plate. An inner channel of the lower air dispersing device is communicated with an inner channel of the upper air dispersing device through the inner air channel hole. By means of the upper blade, ore pulp above the impeller is stirred and guided air is dispersed with force, and therefore the circulation of the ore pulp at the bottom ofa flotation machine and the dispersion of the guided air are fused by means of the upper blade and the lower blade, the upper limit width of the conveying area of the flotation machine is increased,the requirements for powerfully stirring the ore pulp and dispersing the air in a stirring and mixing area of the flotation machine are met, and the requirements for effective air dispersion and ore pulp circulation of the operation central area of the conveying area are met.

An object of the present invention is to solve the problems in conventional art antigen exposure chambers, and specifically, to provide an antigen exposure chamber system capable of simultaneously exposing a large number of test objects in a chamber to a uniform antigen (pollen, mite or house dust, etc.) in all seasons. In order to achieve the above object, in an antigen exposure chamber system according to the present invention, an outdoor air is supplied via an outdoor air diffuser 2 provided in a ceiling surface of an exposure chamber 1 into the exposure chamber from the ceiling surface of the exposure chamber in a horizontal direction, a fan unit 15, including a supply port and a suction port, is provided in each of the four corners of the exposure chamber to provide a circulating flow of air flowing with circulation in the horizontal direction in the exposure chamber, an air exhaust port 4 is provided at a floor surface of the exposure chamber to exhaust an air from the floor surface of the exposure chamber, an antigen is supplied from an antigen supply device to the outdoor air diffuser provided on the ceiling surface so that the antigen is mixed with the outdoor air, and a uniform concentration antigen exposure is enabled by the circulating flow of air.

The invention relates to a floor air conditioner indoor set, which comprises a casing, an air outlet frame, an air passage assembly and a rotary driving device, wherein an accommodating cavity is formed in the casing; the air outlet frame and the air passage assembly are positioned in the accommodating cavity; an appearance panel and an air dispersion panel are arranged at two sides of the air outlet frame; the appearance panel and the air dispersion panel can circumferentially move through the rotary driving device for opening and closing an air outlet; miniature air dispersion holes are uniformly formed in the air dispersion panel. Therefore during the conventional normal air outlet, the appearance panel and the air dispersion panel circumferentially move to the two sides of the air outlet frame; when a breeze outlet mode needs to be started, the air dispersion panel moves to the air outlet part along a circumferential rack through the rotary driving device; the air outlet is completely blocked; concentrated strong airflow subjected to heat exchange becomes softer after the spreading by passing through the miniature air dispersion holes formed in the air dispersion panel; the cool / hot feel and the breeze outlet are realized. The invention also relates to a control method of the floor air conditioner indoor set.
