Abstract
The invention provides a valve core of a nickel flotation machine regulating valve. The valve core of the nickel flotation machine regulating valve comprises a valve core, a valve pocket and a base. The valve core is hemispheric. The spheric arc surface of the valve core is an MATLAB fitted curve. The valve core is connected with the base. The valve pocket is wrapped on the valve core. The base is provided with a transverse fixing pin mouth. The radius of the valve core is the distance from the center of the valve core of the regulating valve to the farthest end of the valve core arc surface of the regulating valve. The range of the valve core is the distance from the upper edge of the valve core of the regulating valve to the bottommost end of the valve core arc surface of the regulating valve. The radius value of the valve core is 290 mm. The range of the valve core is 0 mm-350mm. The valve core of the nickel flotation machine regulating valve provides a valve core shape of the regulating valve and confirms the best operating range of the valve core. The valve core shape of the regulating valve is further modified. The valve core arc surface utilizes the MALAB fitted curve to shorten the valve core range of the regulating valve. Control is easy to achieve and material which is used for manufacturing the valve core is saved. Advantages are provided for the stable control of a foam layer of a flotation machine. The problem that the range of the valve core is oversize so as to be bad to practical control on the spot is solved.
Description
Technical field
The present invention relates to mechanical automation and make 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 of 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 no specifically the research for flotation machine regulation valve core shape, be only 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.
Summary of the invention
In sum, the object of the present invention is to provide a kind of nickel flotation machine regulation valve core.
The objective of the invention is to realize 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 its spherical cambered surface is the MATLAB matched curve; Spool is connected with base; Valve pocket is wrapped on spool; Base is provided with horizontal Fixed latches mouth.
The radius of above-mentioned spool refers to that the regulation valve core center is to the distance of regulation valve core cambered surface distal-most end; The stroke of spool refers on regulation valve core along the distance to regulation valve core cambered surface lowermost end.
The radius value of above-mentioned spool is 290mm; The stroke of spool is 0mm～350mm.
Regulation valve core cambered surface of the present invention 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:
Result after with upper Formula Input Technology is with the equation editing device in word:
Can find out from upper formula, the coefficient of second x front is too little, for the value of x in reality, can ignore for second, and after ignoring, this formula just becomes a parabola.
In this formula: y represents spool stroke, and x represents the spool radius.
Realize by above technology, the regulation valve core curve is as shown in Figure 2 up till now:
Advantage of the present invention and beneficial effect:
The present invention 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 to control to be easy to realize and to save manufacturing spool material therefor, for the stable control of foam layer in flotation machine provides advantage, solution regulation valve core stroke is excessive is unfavorable for on-the-spot working control.

The radius of spool 1 refers to that the regulation valve core center is to the distance of regulation valve core cambered surface distal-most end; The stroke of spool 1 refers on regulation valve core along the distance to regulation valve core cambered surface lowermost end.
The radius value of spool 1 is 290mm; The stroke of spool 1 is 0mm～350mm, and the travel range reasonable and that optimize that is in 20mm～300mm for stroke of regulating valve provides condition; And its regulation valve core cambered surface 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 use MATLAB emulation.
Result after with upper Formula Input Technology is with the equation editing device in word:
Can find out from upper formula, the coefficient of second x front is too little, for the value of x in reality, can ignore for second, and after ignoring, this formula just becomes a parabola.
In this formula: y represents spool stroke, and x represents the spool radius.
Realize by above technology, the regulation valve core curve is as shown in Figure 2 up till now:
Embodiment
In the nickel sulfide ore flotation operation, if old regulation valve core can not use, first unload horizontal Fixed latches from horizontal Fixed latches mouth 4, base 3 and spool 1 are pulled out, then change new spool 1, insert horizontal Fixed latches from horizontal Fixed latches mouth 4 again, fix, can use.
