Technical Field
The invention belongs to the technical field of spraying dust-settling devices, and particularly relates to a nozzle angle adjusting device and a spraying machine.
Background
With the development of environmental protection technology, the spraying machine is widely applied. The dust fall principle of the sprayer is that high-pressure water is atomized by a nozzle and then sprayed into air containing various dust particles, and atomized water drops interact with the dust particles to enlarge and weigh the dust particles, so that the dust particles are accelerated to settle, and the effect of purifying ambient air is achieved.
Practice shows that strong interaction exists among fog drops sprayed by a nozzle of the sprayer and between the fog drops and air flow, the effect can influence the range of the sprayer and the distribution of the particle size of the fog grains, and therefore the dust fall effect of the sprayer is greatly influenced. The nozzle installation angle can directly influence the interaction between the fog drops and the air flow, so that the performance of the sprayer can be greatly influenced. In reality, in order to obtain good dust fall effect, the change of different ranges and particle sizes is often required, and in order to adapt to different working conditions and obtain better performance, the nozzle angle is also required to be adjusted.
Many have proposed various solutions for adjusting the nozzle angle. Patent CN202021640290.3 is a sprayer with a rotatable nozzle, the proposed solution is complex in structure, each nozzle needs to be adjusted by a stepping motor, and the sprayer is suitable for sprayers with a small number of nozzles, and is not suitable for sprayers with a number of nozzles of dozens or even hundreds. Patent CN202111206243.7 is a dust fall fog gun machine that radiation radius is adjustable, and it needs to set up a fan group, blows the aerofoil with a plurality of fans, then every aerofoil promotes a nozzle and rotates, and too many not only make the structure too complicated of fan, also mean to have great difference with the sprayer structure that now generally adopts.
The nozzles of a dust-settling sprayer are often dozens or hundreds, the direction of each nozzle is different, but the nozzles generally have the same angle with the axis of the sprayer, so that the nozzles are required to be uniformly adjusted, and the above schemes are difficult to realize. Patent CN202110200107.0 spouts ring and an air-assisted sprayer of adjustable nozzle angle, a solution is proposed, adopt the nozzle of taking the ball hinge, pass the alignment jig who opens waist-shaped groove, change the angle of nozzle through rotating the alignment jig, the structure is exquisite, but comparatively complicated, the big piece processing degree of difficulty of taking three-dimensional curved surface and curve groove is great, many places gear engagement will guarantee the synchronization, the operational reliability is difficult to guarantee, and adjustable angle's scope is less, also the ball hinge operating time has long defect such as easy water leakage, be difficult to satisfy the in-service use requirement completely.
