The valve element body is semi-spherical, and an outer edge line of a spherical cross section is a curved line. The valve element body is connected with the base. The valve sleeve wraps the valve element body. The base is provided with a transverse fixed bolt port. According to the nickel floating machine adjusting valve element, the shape of the adjusting valve element is determined, the best operation range of the valve element is determined, and the shape of the adjusting valve element is further improved; the cambered surface of the adjusting valve element is a MATLAB fitted curve, strokes of the adjusting valve element are shortened, therefore, control can be achieved easily, materials for manufacturing the valve element are saved, favorable conditions are provided for stable control over foaming layers in a floating machine, and the problem that on-site actual control is not facilitated because the strokes of the adjusting floating machine are too large is solved.
Description
Technical field
The utility model relates to mechanical automation and makes the field, is a kind of nickel flotation machine regulation valve core specifically.
Background technique
The production of Jinchuan copper and nickel resources in China's nickel and platinum group metal occupies absolute status, and Jinchuan Group nickel metal output accounts for more than 85% of the whole nation.At present, the nickel resources recovery rate in ore-dressing of Jinchuan Group can reach 88% (average 85%) preferably the time, and external average recovery rate can reach 90%, so be badly in need of accelerating the optimization research of its floating process.
The late 19th century, froth flotation begins formally to be used in Practice of Beneficiation as a kind of plant-scale method, and from then on Floatation Industry has obtained to develop rapidly, so far the history in existing 100 years.In the past few years, many experts and scholars have done a large amount of research and development to the floating process of Jinchuan copper-nickel mine stone, particularly for the characteristics of China's ore resource, research and the commerical test of concentrate content of magnesia have been carried out reducing, the different research aspects such as floating agent, technological process, flash flotation have wherein been contained, but there is not specifically the research for flotation machine regulation valve core shape, only be with a kind of traditional smoothed curve, do not consider that the regulation valve core shape is on the impact of floating product concentrate quality and the recovery rate.
The nickel flotation machine regulation valve core of prior art designs according to traditional empirical data, its control precision is poor, the control reaction velocity is slow, is unfavorable for the stable control of depth of foam between the flotation machine cascade, causes impact and the coupling of flotation machine between mutually large.
The model utility content
In sum, the purpose of this utility model is to provide a kind of nickel flotation machine regulation valve core.
The purpose of this utility model realizes by following technology:
A kind of nickel flotation machine regulation valve core comprises spool, valve pocket and base, and it is hemispherical that spool is, and the outer of its bulbous section is curve along the line; Spool is connected with base; Valve pocket is wrapped on the spool; Base is provided with horizontal Fixed latches mouth.
Above-mentioned curve is satisfied with in MATLAB software
Equation, wherein y represents spool stroke, span is 0mm～350mm; X represents the spool radius, and span is 290mm～0mm; E is the presentation of giving tacit consent in the MATLAB software, and e-016 represents 10-16 powers in the equation, is fixed value.
Above-mentioned spool radius refers to that the regulation valve core center is to the distance of regulation valve core cambered surface distal-most end; Spool stroke refers on the regulation valve core along the distance to regulation valve core cambered surface lowermost end.
Regulation valve core cambered surface of the present utility model definite uses the MATLAB matched curve, and curvilinear equation is:
The explanation of regulation valve core matched curve equation:
Carry out curve fitting with MATLAB emulation, can obtain this curvilinear equation and be:
, this formula is the direct Output rusults of computer after the use MATLAB emulation.
In word with the result of equation editing device after with upper Formula Input Technology be:
Can find out that from upper formula the coefficient of second x front is too little, for the value of x in the reality, can ignore for second that this formula just becomes a parabola after ignoring.
In this formula: y represents spool stroke, and x represents the spool radius, and e well known to a person skilled in the art constant, and e is the presentation of giving tacit consent in the MATLAB software, and e-016 represents 10-16 powers in the equation, is fixed value.。
Realize by above technology, the regulation valve core curve is as follows up till now:
Advantage of the present utility model and beneficial effect:
The utility model has provided a kind of regulation valve core shape, determined spool optimum operation scope, further improved the regulation valve core shape, its regulation valve core cambered surface MATLAB matched curve, shortened the regulation valve core stroke, make control be easy to realize and save and make the spool material therefor, for the stable control of foam layer in the flotation machine provides advantage, solve that the regulation valve core stroke is excessive to be unfavorable for on-the-spot working control.
