1, in production scene, the water quality of on-site is too hard, hydraulic pressure is unstable, and this is mainly because Anhui exploitation mining industry Co., Ltd present position is Huoqiu County Zhou Ji---and inn with a stable one is with, and in water shortage and water, calcium content is high, very easily precipitates fouling.And the water formation negative pressure of utilizing just that this automatic medicament feeding system adopts causes the stroke pressure of chemical feed pipe inner membrance that medicament is got to medicine adding platform, water quality hydraulic pressure is the CCP of this cover medicine system.Due to the problem of water quality hydraulic pressure, caused the unstable of chemical feeding quantity.
2, the designed feed line diameters of this medicine system is less, the on-the-spot medicament using has four kinds, respectively collecting agent (fatty acid), starch, lime, sheet alkali, due to stickiness and the easily character of precipitation of lime of starch, collecting agent, chemical feed pipe can often stop up, and is also to cause the chemical feeding quantity factors of instability simultaneously.
What 3, the medicament pipeline of this medicine system adopted is plastic material, and on-the-spot desired collecting agent and starch serviceability temperature are all more than 60 ℃, medicament pipeline very easily damages (as figure five), also cause the inner membrance of grug feeding jar very easily to damage in production scene, need to expend a large amount of original this systems of safeguarding that is produced into simultaneously.
4, the configuration of collecting agent and starch medicament need be carried out under the temperature more than 90 ℃, this medicine system is to utilize Steam Heating, jet chimney is directly passed in compounding bin, steam directly contacts (as figure six) with medicament, this can cause the water in steam constantly to enter in medicament, for guaranteeing medicament serviceability temperature, need ceaselessly to medicament, heat, after a period of time, the concentration of medicament can be diluted, and has a strong impact on the result of use of medicament.
Utility model content
The purpose of this utility model is the deficiency in order to make up prior art, and a kind of flotation gravity flow chemicals dosing plant is provided, and its simple to operate, upper dose is stablized, can not be stopped up, maintenance cost is low.
The utility model is achieved through the following technical solutions:
A kind of flotation gravity flow chemicals dosing plant, include flotation device platform, it is characterized in that: on described flotation device platform, set up successively four medicine-chests, described medicine-chest is respectively the medicine-chest of dress collecting agent, the medicine-chest of dress starch, the dress medicine-chest of lime and the medicine-chest of load alkali, and the medicine-chest of dress lime is provided with agitating device, on described medicine-chest, be respectively equipped with medicament overflow Returning pipe and medicament discharge pipe, in described medicine-chest, be respectively equipped with steam-heated pipe line, the exhaust outlet of described steam-heated pipe line is communicated with the air inlet of steam generator, described medicine-chest connects with corresponding compounding bin respectively by medicament feed pipeline, and be provided with valve in medicament feed pipeline.
