Abstract
The invention discloses a driving device for a coal jig machine numerical control air valve, capable of saving energy, protecting environment and reducing maintenance and production costs. The driving device comprises a valve seat (9), a valve core (8), a sealing device (7), an air inlet chamber (10), and an air outlet chamber (11), wherein the bottom end of a connecting rod (6) is connected with the valve core (8), and the upper end of the connecting rod (6) is fixedly connected with a sliding plate (13) and a linear motor rotor (1), and the sliding plate (13) is matched with linear guide rails (3) on a support (12) by linear guide rail sliders (4), a linear motor stator (2) is matched with the linear motor rotor (1), and a magnetic grid sensor (5) can generate feedback signals to control the linear motor rotor (1) and the linear motor stator (2). The driving device is applicable to a coal jig machine.
Description
Technical field
The present invention relates to a kind of drive unit of coal jigging machine numerical control wind valve.
Background technology
From the seventies in last century so far, coal separation industry 30 years, generally adopt national coal mine machinery research institute, the pneumatic mechanism of development is as the executive system of its air-valve, main employing pneumatic control comprises: air compressor machine, triplet, magnetic valve, cylinder, tracheae circuit, therefore this control mode complex structure exists problems.
1, contains a large amount of dust in the air of coal washery, the equipment operate as normal is caused irreversible damage.
2, cheap piston type air compressor is generally adopted in the coal washery, this air compressor machine continuous operation life-span is not long, the easy unstability of air pressure, and have a large amount of full-bodied machine oil and water in the compressed air easily, give the executive component of back, caused fatal influence as magnetic valve, cylinder operate as normal.The piston type air compressor energy conversion efficiency is not high, and power consumption is all left and right at 15KW/h usually, and energy consumption is big, and can produce very big noise when work.
Summary of the invention
The technical problem to be solved in the present invention is: the drive unit that a kind of coal jigging machine numerical control wind valve is provided, this device can energy savings, alternative current fully coal separation industry is used, and with the executive system of compressed air as the electromagnetic air valve of power, reduces production costs greatly.
For solving the problems of the technologies described above, the present invention has valve seat, spool, sealing device, inlet plenum, exhaust chamber, the bottom of connecting rod connects spool, the upper end is connected with slide plate and linear motor rotor, slide plate cooperates with line slideway on being arranged on bearing by the line slideway slide block, linear motor stator electric cooperates with linear motor rotor, and magnetic induction sensor generates feedback signal control linear motor rotor and linear motor stator electric.
Adopt the present invention that following advantage is arranged:
1, minimizing maintenance of equipment expense simple in structure substitutes the executive system that has coal jigging machine numerical control electromagnetic air-valve now fully, reduces production costs greatly.
2, only on linear electric motors, about about 1KW/h, and the main energy consumption of traditional numerical control electromagnetic air-valve is the power consumption of air compressor machine to power consumption of the present invention, generally can not be lower than 15KW/h, and the present invention is whole energy more than 90% compared with prior art.
3, environmental protection low-carbon (LC): the present invention does not need consumed cabin air, to the pollution of air, does not have noise.
4, efficient height: the speed of service of linear electric motors is fast, can realize 5m/s, far above the speed of cylinder, controls the action of jigging easily, and the positioning accuracy height can be up to 0.001mm, and this is that cylinder institute is irrealizable at all.With this, be easy to air-valve motion is carried out more accurate setting to charging period, the phase of expansion, exhaust cycle, stand-down 4 frequencies, the range parameter of jigging, put forward effect and the efficient of doing coal washing greatly, improve the quality of output and coal separation.

The specific embodiment
By Fig. 1, Fig. 2, Fig. 3, Fig. 4 as can be known: the present invention has valve seat 9, spool 8, sealing device 7 inlet plenums 10, exhaust chamber 11, the bottom of connecting rod 6 connects spool 8, the upper end is connected with slide plate 13 and linear motor rotor 1, slide plate 13 cooperates with line slideway 3 on being arranged on bearing 12 by line slideway slide block 4, linear motor stator electric 2 cooperates with linear motor rotor 1, and magnetic induction sensor 5 generates feedback signal control linear motor rotor 1 and linear motor stator electric 2.Bearing 12 is fixed on the valve seat 9.
Use the present invention, linear motor rotor 1 drives spool 8 by connecting rod 6 and does upper and lower moving, so that the work of coal jigging machine.
