Problems solved by technology

The prior art has the following defects: 1. It is difficult to control the spray volume, and the spray effect is not good. Controlling the spray volume by adjusting the flow and pressure of the spray liquid can easily cause changes in the size of the droplets. The size of the droplets is too large to affect the uniformity of the spray. If it is small, it will cause the mist to drift away
Moreover, the spray volume of this spray device is unevenly distributed within the effective spray range of the spray head, which is easy to cause overlapping spraying or missed spraying in adjacent spraying intervals, and it is also difficult to achieve horizontal partition control spraying.
2. It cannot be sprayed downwards. Due to the problem of dripping during the spraying process, the existing technology can only spray upwards or horizontally.

Abstract

The invention discloses the sprayer unit used for chemical adjuvant spraying in paper industry. The sprayer unit comprises spraying chest, spraying head, spraying head regulating mechanism, spraying guide mechanism, spraying content control mechanism and coagulation liquid reflux mechanism. The spraying head regulating mechanism comprises regulation segment and instalment segment, and the spraying head fixed in spraying chest is connected with regulation segment through instalment segment. The spraying guide mechanism comprises preposition guide tube and baffle installed on the exit of spraying chest. The preposition guide tube fixed on the two side walls of spraying chest is between spraying head and baffle. The external surface of preposition guide tube is downward bent camber, useful for spraying. The unit has the advantages of good spraying effect, downward spraying and reclaiming condensation liquid.

Description

technical field [0001] The invention relates to an industrial spraying device, in particular to a spraying device used for spraying chemical additives in the spraying process of the papermaking industry. Background technique [0002] At present, chemical auxiliaries in the spraying process of the paper industry are generally sprayed by spray heads, and the spray volume is controlled by adjusting the pressure and flow rate of the spray entering the spray head through valves. This spray device is comparatively primitive, and the spray head is contained on the spray pipeline that is connected with valve and just uses directly. The prior art has the following defects: 1. It is difficult to control the spray volume, and the spray effect is not good. Controlling the spray volume by adjusting the flow and pressure of the spray liquid can easily cause changes in the size of the droplets. The size of the droplets is too large to affect the uniformity of the spray. If it is too small...
