Spraying device

Abstract

The invention discloses a spraying device, which comprises a spraying pipe. A discharging hole with a base is arranged at one end of the spraying pipe, a distribution plate is arranged at the lower end of the base, and a connecting rod which is connected with the distribution plate penetrates through the base into the spraying pipe. A pull rod with a slope at one end is arranged inside the spraying pipe, and the connecting rod is movably connected to the slope. The reciprocating motion of the pull rod drives the connecting rod to slide along the slope. The other end of the pull rod is connected with a driving mechanism which drives the pull rod to move reciprocatingly so as to drive the distribution plate to move upwards and downwards and adjust the gap between the distribution plate and the base. Accordingly, the amount and effect of spaying are adjusted and even spaying can be achieved.

Description

technical field [0001] The invention relates to a liquid atomizing spraying device, in particular to a spraying device with adjustable spray volume. Background technique [0002] The spray device is a device that sprays liquid materials, solutions, water and other liquid substances with high pressure and then sprays them with fine water particles to produce an atomization effect. In the industrial production process, the spray device is widely used, and its atomization effect depends on Liquid flow, pressure and nozzle design, the spray device commonly used in industrial production at present, the nozzle is directly installed on the spray pipe, and the spray liquid is directly sprayed from the nozzle through the spray pipe. [0003] Such as figure 1 , is an existing simple spray device, the nozzle 2a is installed at the end of the spray pipe 1a, the high-pressure liquid flows in from the spray pipe 1a, and is atomized and sprayed out through the nozzle 2a. This spray device...

Problems solved by technology

[0003] like figure 1 , is an existing simple spray device, the nozzle 2a is installed at the end of the spray pipe 1a, the high-pressure liquid flows in from the spray pipe 1a, and is atomized and sprayed out through the nozzle 2a. This spray device is often used in industrial production, and it can cooperate with continuous production. , although its structure is simple, it has the following defects: 1. The existing spray device cannot adjust the spray volume without changing the nozzle, and can only adjust the spray volume by adjusting the pressure and flow of the spray liquid. The change of liquid pressure will cause the change of droplet size. The spray liquid pressure is too small, the droplet size is too large will affect the uniformity of the spray, the pressure is too high, the droplet size is too small will cause the droplet to drift away; 2. Spray liquid When the pressure changes, it cannot cooperate with the nozzle to achieve the best spray effect, and the nozzle can only be replaced to achieve the best atomization effect, and the operation is cumbersome to replace the nozzle; 3. The spray volume can only be adjusted by adjusting the pressure and flow of the spray liquid , it is difficult to ensure that the amount of spray is always the same, the distribution of spray amount is uneven, the spray effect is not good, and it is difficult to achieve uniform spray
