The utility model discloses a forestry forest pest control pesticide spraying device which comprises a cart, a liquid storage barrel is installed on the cart, a water pump is installed on the bottom side of one end of the liquid storage barrel, the other end of the water pump is connected with a water conveying hose, an air pump is installed at the upper end of the liquid storage barrel, and one end of the air pump is connected with an air conveying hose. When liquid medicine dripped by an arc-shaped dripping head passes through an air nozzle, the liquid medicine is blown to a target forest tree needing to be sprayed under the action of high-pressure air flow, at the moment, the liquid sprayed by the high-pressure air flow is difficult to blow away by blowing of natural wind, and wind shields are mounted on the peripheral sides of a first fixing sleeve and a second fixing sleeve at the upper end of a rotating shaft; and the bottom side wall of the wind shield inclines towards the liquid storage barrel and is connected with the backflow corrugated pipe, so that when natural wind is blocked by the wind shield, liquid medicine which drips and is not blown out can be effectively collected and flows back into the liquid storage barrel along with the backflow corrugated pipe, and waste of the liquid medicine is avoided.

This invention discloses a heat dissipation control method and device based on the synergistic coupling of piezoelectric jet and thermoelectric cooling. The heat dissipation control method includes: controlling a piezoelectric ceramic driving plate to drive an intake flexible valve plate to generate periodic bending deformation, thereby changing the volume of the compression chamber, so that the compression chamber alternately performs the intake process and the compression process; during the compression process, when the pressure difference between the compression chamber and the external environment pressure reaches the opening threshold determined by the pre-tightening force and effective pressure area of ​​the outlet flexible valve plate, the outlet flexible valve plate passively generates an opening deformation, so that the cooling fluid in the compression chamber is injected into the air inlet of the heat exchange module in the form of a jet through the air outlet; the heat from the heat source is absorbed by the cold end of the thermoelectric cooling module, and the heat is transferred to the hot end of the thermoelectric cooling module, and then transferred to the heat exchange module, and carried away by the cooling fluid injected from the air inlet of the heat exchange module, fundamentally avoiding the risk of fatigue failure of traditional mechanical valve plates.

The invention relates to the technical field of sewage, in particular to a papermaking sludge online treatment device which comprises a machine base, the upper end of the machine base is fixedly connected with a flocculation assembly and a sludge treatment mechanism, the flocculation assembly comprises a mixing mechanism and an anti-blocking mechanism, the mixing mechanism comprises a mounting shell, a mounting base, an S-shaped pipeline, a driving rod and a driven rod, the mounting shell is arranged on the machine base, and the sludge treatment mechanism is arranged on the mounting base.
