Description

High-evaporation-capacity low-pressure spray head Technical Field The invention belongs to the technical field of sprinkling irrigation equipment, and particularly relates to a high-evaporation-capacity low-pressure sprinkler. Background The low-pressure spray head is a fluid spraying device for realizing atomization, spraying or evaporation of liquid by crushing the liquid under low-pressure input, can reduce energy consumption and operation cost, and is widely applied to the fields of industry, mining industry and the like. For example, in industrial wet smelting, acidic or alkaline stock solution is sprayed by a low-pressure spray nozzle, the stock solution is covered on the surface of ore material in a fine mist form to realize chemical leaching of valuable metals such as copper, but as the wet smelting is continuously produced, waste liquid such as reaction residual liquid is continuously accumulated, the liquid amount of the low-pressure spray nozzle with small evaporation amount which can be atomized and evaporated in unit time is limited, the waste liquid can be easily absorbed or the volume reduction speed is delayed from the production speed, the waste liquid accumulation and environmental protection risks are caused, the uneven spraying effect also can cause the ineffective loss of the stock solution to be greatly increased, the cost of copper smelting raw materials is increased, meanwhile, the underreacted stock solution can be converted into more waste liquid, the load of the treatment of the waste liquid at the rear end is further increased, and the problems of obvious cost waste and waste liquid recovery are faced, so that a high evaporation amount low-pressure spray nozzle needs to be developed, and the combination uniformity is improved, so that the requirements of the recovery of the waste liquid in modern industry and the cost are met. Typical working pressure range of the swing spray head is 150kPa to 400kPa, spraying radius can reach 5-8 meters, and the swing spray head still has strong adaptability under low-pressure irrigation working conditions. Compared with other rotary spray heads, the swing spray head has the core advantages that the spray head is driven by water flow to enable the water dispersing disc with an offset flow channel to generate rotary motion, and the direction of water jet is periodically changed under the synergistic effect of the swing limit structure, so that more uniform water distribution is formed in a spraying area, but the swing spray head is applied to mining industry, and has the main defects and technical bottlenecks that the large evaporation amount, the combination uniformity and the range of the spray head are difficult to be simultaneously considered, the structural form of each flow channel in the water dispersing disc is basically consistent, the water distribution is realized only by changing the spraying angle according to the swing limit structure in the traditional swing spray head, the evaporation amount is insufficient, the truly uniform spraying effect is difficult to be realized, the phenomenon of local overwetting or overdrying is easy to form in the spraying area, the whole quality is further reduced, the mining area system is difficult to achieve the balance of waste liquid, the range is also easy to be greatly reduced or the normal rotation under low pressure is difficult to cause, the pipeline spacing in the combined use is reduced, and the pipeline investment in the spray irrigation system is reduced. In addition, the water dispersion disc and the swinging body are of an integrated structure, and the water dispersion disc can be worn and not easy to replace in the long-time spraying process, so that the spray disc can only be replaced integrally when worn, and the replacement cost is high. Disclosure of Invention The invention aims to solve at least one of the technical problems to a certain extent, and provides the high-evaporation-capacity low-pressure spray head which can give consideration to the range and stable operation characteristics under the low-pressure working condition, effectively improves the atomization evaporation capacity and the combination uniformity of the spray head, and is easy to assemble, disassemble and replace so as to meet the requirements of recovery of modern industrial waste liquid in mining industry and the like and cost saving. The technical scheme adopted for solving the technical problems is as follows: The utility model provides a large evaporation capacity low pressure shower nozzle, includes runner pipe and the nozzle of intercommunication, be equipped with first spacing body, second spacing body on the runner pipe, be located movable mounting's between first spacing body and the second spacing body and sway the body, it is connected with the water dispersion dish to sway the body, the water dispersion dish is equipped with the water dispersion needle that is located the center, around the water
