The utility model discloses an air purifier belongs to air purification equipment technical field. It includes: air inlet pipe and air outlet pipe, both upside down and connect, and both the top surface, bottom surface of air purifier structure formed after connecting are closed surface, the top surface of air outlet pipe is provided with the communicating port, and the inner chamber of air inlet pipe is communicated with the air outlet pipe through the communicating port, the circumferential side wall of air inlet pipe is provided with a plurality of air inlet face, and every air inlet face is provided with air inlet, the air outlet face is formed on the opposite setting two sides of air outlet pipe respectively, and every air outlet face is provided with air outlet, the filter screen is set in air inlet pipe and covers in communicating port. Set up air inlet and air outlet on every side wall of air inlet pipe and air outlet pipe respectively, can handle the air in larger range fast, realizes the uniform suction and high -efficient discharge of air, effectively promotes the air circulation times in unit time, thereby significantly enhances purification efficiency.

The present application relates to the technical field of air purifiers, and specifically provides a wind channel assembly, an air purifier and a wind channel assembly control method.The wind channel assembly comprises a centrifugal fan, a first shell and a flow guide piece;the centrifugal fan is provided in multiple parallel and sequential intervals;the first shell is arranged outside the centrifugal fan and is connected to the centrifugal fan;the first shell is provided with multiple wind channels corresponding to the centrifugal fan in one-to-one correspondence;the wind channel comprises a first air inlet and multiple first air outlets;the first air inlet is used for introducing airflow filtered by a target filter with a target resistance into the wind channel;the multiple first air outlets are arranged on the outer periphery of the centrifugal fan;the flow guide piece is arranged in the first shell and is connected to the first shell;the flow guide piece is arranged between two adjacent centrifugal fans to separate the wind channels;the flow guide piece is provided with flow guide concave arc surfaces on both sides, and the flow guide concave arc surfaces are configured to guide the airflow of a target fan to the first air outlet. The present application can provide large airflow while taking into account low noise and energy consumption.

The utility model relates to the field of sewage treatment, and disclose a kind of multistage percolation purification artificial wetland, including primary filter tank, the inside movable joint primary percolation layer of primary filter tank, the side fixed connection of primary filter tank has secondary filter tank, the inside movable joint secondary percolation layer of secondary filter tank.The multistage percolation purification artificial wetland, by setting primary filter tank, primary percolation layer, secondary filter tank, secondary percolation layer, filter plate one, tertiary filter tank, tertiary percolation layer, filter plate two, filter plate, liquid storage frame, liquid pumping pipe, liquid pumping equipment, liquid discharge screw pipe and lower rotating screw lock, can make the multistage percolation purification artificial wetland more convenient to use, can be conveniently collected to purified sewage, to improve the utilization rate after sewage purification, reduce the purification pressure of artificial wetland, improve the purification speed of subsequent sewage, conducive to long time work of multistage percolation purification artificial wetland.

The utility model discloses a high-density pool for sewage treatment, which comprises a stable support frame, a first sewage treatment box arranged at the upper end of the stable support frame, a second sewage treatment box arranged at the rear end of the first sewage treatment box in a communicated manner, a first mounting plate, a second mounting plate and a second mounting plate, and a first mounting plate is fixed to the upper side of the first purification cavity, a first mounting motor is arranged in the middle of the first mounting plate, a first stirring rod is coaxially connected to the lower end of the first mounting motor, and a second purification cavity is formed in the right side of the first purification cavity. According to the high-density pool for sewage treatment, the problems that although an existing high-density pool can improve the operation efficiency during sewage treatment, rapid stirring and purification speed acceleration are not convenient to carry out after chemicals are added, a better purification effect is not convenient to achieve, sludge at the bottom is not convenient to better and more comprehensively remove, and the working efficiency is not improved are solved.
