The invention discloses a water level control device of a humidifier and the humidifier applying the same. The water level control device comprises a water tank and a base of the humidifier, wherein a steam generating chamber is arranged in the base; a drain hole is formed in the water tank, and a drain valve is arranged in the drain hole; the water level control device in sleeved connection with the drain valve is arranged in the steam generating chamber, the water level control device comprises a limiting hood opened in the peripheral wall, a water outlet is formed in the top of the limiting hood, and a floating block is arranged in the limiting hood; a leak hole plug is arranged at the water outlet, and the bottom of the leak hole plug is a part in contact with the floating block; the floating block shifts up and down in the limiting hood along with change of the water level; when the floating block is in contact with the drain hole plug, the water outlet is plugged to stop draining; otherwise, the floating block is separated from the leak hole plug, and the water outlet is opened to supplement water. The water control device disclosed by the invention is simple in structure and small in occupied space, is immediately triggered to control water supplementation for the steam generating chamber, and is electric energy-saving, and the condition that the humidifier is likely to overflow or dry out is effectively avoided, so that a user can use the humidifier safely.

The invention belongs to the technical field of the water ecological environment, and particularly to a device and a method for stimulating pollutant transport and upstream salty water of a riverway with a repeated tidal flow. The device comprises an upstream flow control device, a middle water tank device and a downstream tidal flow control device, and is characterized in that the upstream flow control device comprises a water inlet pipe, a constant flow water tank and an upstream water level control water tank; the middle water tank device comprises a water tank body, a speed measuring device and a pollutant sewage inlet tank; the downstream tidal flow control device comprises a tide water level control water tank, a tide backflow stimulation water tank, a compensation or seawater salinity stimulation water tank; the upper end of the water tank body is connected with the upstream water level control water tank while the lower end thereof is connected with the tide water level control water tank; the tide water level control water tank is connected with the tide backflow stimulation water tank; the compensation or seawater salinity stimulation water tank is connected with the tide backflow stimulation water tank. The device and the method for stimulating pollutant transport and upstream salty water of riverway with the repeated tidal flow can stimulate transport and diffusion rules of the pollutants in the riverway with the repeated tidal flow (the upstream salty water rules), and can be widely applied to the simulation tests in the technical field of the water ecological environment.

The invention discloses an apple floating and feeding device. The device comprises a feeding water tank, a conveying belt and a fruit dividing plate, the feeding water tank comprises a draining tank and a fruit pouring tank, the draining tank is communicated with the fruit pouring tank, a first annular groove and a second annular groove are arranged in the inner wall of the fruit pouring box; theposition of the first annular groove and the position of the second annular groove are oppositely arranged; a first chain is arranged in the first annular groove, and a second chain is arranged in thesecond annular groove, the two ends of the fruit dividing plate are respectively connected with the first chain and the second chain; a first motor is arranged on the outer side of the draining box,the first motor is connected with the second chain; a conveying belt is obliquely arranged in the draining box, the lower end of the conveying belt is arranged below the first annular groove and the second annular groove; anti-rolling blocking strips are uniformly arranged on the conveying belt, a second motor is arranged on the outer side of the draining box, and the second motor is connected with the conveying belt.

The invention discloses a steam-water separator. The steam-water separator comprises a barrel, an upper end enclosure, a lower end enclosure, an even number of steam inlet pipes and a steam outlet pipe. The steam inlet pipes are symmetrically arranged on the outer side of the upper portion of the barrel about the central axis of the barrel. The steam outlet pipe is arranged at the top of the upper end enclosure and stretches into the barrel, and a drainage device is arranged at the bottom of the lower end enclosure. A conical plate coaxial with the barrel is arranged on the lower portion of the barrel, the vertex of the conical plate is arranged upwards, a porous plate is arranged on the lower portion of the conical plate, the outer diameter of the conical plate is smaller than the inner diameter of the barrel, and the outer diameter of the porous plate is consistent with the inner diameter of the barrel. The steam-water separator of the structure has the advantages that the steam inlet pipes are used for steam inflow, so that steam forms a cyclone flow in the steam-water separator, and the steam-water separation effect is improved.

The invention discloses a composite anti-seepage wall for environmental protection of landfills in soft soil areas and a construction method thereof. The composite anti-seepage wall includes a flexible core wall arranged around the landfill, and the flexible core wall The depth is sufficient to extend from the ground surface and embed into the water-resisting layer. The inner and outer sides of the flexible core wall are respectively provided with plastic walls, and the inner side of the inner plastic wall and the outer side of the outer plastic wall are respectively provided with supporting walls. A transition zone is set between the supporting wall on the inner side and the landfill, and a groundwater pumping and drainage well is set in the transition zone. According to certain procedures, the present invention constructs a support wall, vertically slots, vertically installs a flexible core wall, makes plastic concrete according to a specific ratio, and adopts an underwater pouring method to construct a plastic wall. Under the premise of stable embankment and foundation, it can effectively isolate the accidental leakage of hazardous waste landfill and protect soil and groundwater.
