One end of the cylinder barrel is open while the other end of the cylinder barrel is provided with a bottom wall, a piston is slidably connected in the cylinder barrel and contacts with the same closely, a space between the piston and the bottom wall of the cylinder barrel serves as an isolating chamber, the bottom wall is provided with a connecting hole, and the isolating chamber is filled with hydraulic oil. A fixing flange is fixedly connected to the outer side of the open end of the cylinder barrel and provided with fixing holes. Both a seal ring and a supporting ring are connected to the piston and disposed between the piston and the cylinder barrel. A connecting pipe is communicated with the connecting hole hermetically. The dense-medium coal slime damping buffer is capable of isolating and buffering a medium pressure transducer lastingly effectively, thereby guaranteeing normal running of the medium pressure transducer and providing accurate pressure parameters to coal dressing production.
Description
Technical field
The present invention relates to a kind of heavy media coal separation industry cyclone separator material entrance pressure medium converter protecting apparatus, relate in particular to a kind of dense media black water damping antidetonation device.
Background technique
In the heavy-media coal preparation process, the size of cyclone separator material entrance pressure medium is to guarantee the important technical parameter of the quality of cleaned coal and the recovery rate.In automatic control system, the pressure at cyclone separator material entrance place is by the pressure transducer collection, and on-line measurement also is sent to master-control room demonstration pressure data; Can react the working condition of cyclone separator at any time through data; Can judge that pipeline or cyclone separator have or not obstruction, medium pump has or not changes stifled, has or not race leakage or liquid level to cross situation such as low; Therefore, the inlet pressure parameter of cyclone separator is significant to guaranteeing quality of product and clean coal recovery.
Pressure transducer belongs to precision instrument, if be directly installed on the dense media coal slime feeding pipe place on the cyclone separator, because medium is to be constituted and be mingled with part of coal muddy water by iron powder; At first; Under the effect of pressure, the fine grained iron powder is understood build-up of pressure transducer serious wear or damage to the impact and the vibrations of pressure transducer for a long time, secondly; Thin iron powder and coal slime get into pressure transducer inside and but can not flow out voluntarily; Thereby result in blockage, cause pressure parameter distortion or damage, directly influence quality of product and ordinary production.Therefore, must medium and transducer be isolated for addressing this problem.
At present; The heavy media coal separation industry does not still have permanently effective method cyclone separator material entrance pressure medium transducer is protected; The simple and easy home-made contrivance of most uses; Adopt insulating glove or air tube to be enclosed within on the pipeline medium is isolated, protect pressure transducer, prevent that pressure transducer from damaging to reduce to impact and shake.Because insulating glove and air tube impact resistance are poor, damage easily (must change about half a year), often cause medium to break through isolating film results in pressure transducer and damage, thereby influence the coal separation ordinary production owing to replacing is untimely.
Summary of the invention
The purpose of this invention is to provide that a kind of simple in structure, shock resistance is strong, the dense media black water damping antidetonation device of long service life.
For realizing above-mentioned purpose, the technological scheme that the present invention adopts is:
A kind of dense media black water damping antidetonation device; Comprise cylinder barrel, a wherein end of cylinder barrel has opening, and the other end of cylinder barrel has diapire; It is characterized in that: slidely connect piston in the cylinder barrel; Piston closely contacts with cylinder barrel, and the space between the diapire of piston and cylinder barrel is an isolation ward, has attachment hole on the diapire.
According to described dense media black water damping antidetonation device, it is characterized in that: be provided with hydraulic oil in the said isolation ward.
According to described dense media black water damping antidetonation device, it is characterized in that: the opening end fixed outside of said cylinder barrel is connected with fastening flange, has fixed hole on the fastening flange.
According to described dense media black water damping antidetonation device, it is characterized in that: be connected with seal ring on the said piston, seal ring is between piston and cylinder barrel.
According to described dense media black water damping antidetonation device, it is characterized in that: be connected with supporting ring on the said piston, supporting ring is between piston and cylinder barrel.
According to described dense media black water damping antidetonation device, it is characterized in that: the airtight connecting tube that is communicated with in said connection hole.
The present invention can effectively isolate and damping the pressure medium transducer long-term effectively, thereby guarantees pressure transducer ability proper functioning, for programing in coal preparation provides accurate pressure parameter.
Be fixed on cyclone separator material entrance top through connecting flange when the present invention uses, the free end of connecting tube connects pressure transducer, transmits pressure through piston and hydraulic oil in the production process; Improved the working environment of pressure transducer; Can effectively isolate and damping, stop direct impact and the vibrations of medium, guarantee the pressure transducer proper functioning pressure transducer to medium; Can prolong the working life of pressure transducer, for programing in coal preparation reliable support is provided simultaneously.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is further described:
A kind of dense media black water damping antidetonation device to shown in Figure 5, comprises cylinder barrel 6 like Fig. 1; A wherein end of cylinder barrel 6 has opening; The other end of cylinder barrel 6 has diapire 11, slidely connects piston 5 in the cylinder barrel 6, and piston 5 closely contacts with cylinder barrel 6; Space between the diapire 11 of piston 5 and cylinder barrel 6 is an isolation ward 12, has attachment hole 8 on the diapire 11.In the present embodiment, be provided with hydraulic oil 7 in the isolation ward 12; The opening end fixed outside of cylinder barrel 6 is connected with fastening flange 1, has fixed hole 2 on the fastening flange 1; Be connected with seal ring 3 on the piston 5, seal ring 3 is between piston 5 and cylinder barrel 6; Be connected with supporting ring 4 on the piston 5, supporting ring 4 is between piston 5 and cylinder barrel 6; The airtight connecting tube 9 that is communicated with in attachment hole 8 places.
The seal arrangement of the similar liquid oil hydraulic cylinder of the present invention; During production; The coal slime WATER AS FLOW MEDIUM promotes piston advances forward under the effect of pressure, piston with propagation of pressure to hydraulic oil, be under pressure compression and pressure is sent on the pressure transducer of hydraulic oil; By pressure transducer pressure signal is transformed into electrical signal and is transferred to control terminal, for production provides pressure medium parameter accurately.When production system was out of service, the pressure that acts on the piston reduced gradually, and the pressure that acts on the hydraulic oil also reduces thereupon, and hydraulic oil expands and promotes piston to motion in the other direction, returns initial position until piston.
Hydraulic oil in the isolation ward also plays the effect of lubricated inner wall of cylinder except that as spacer medium, the work of promotion pressure transducer, guarantees the activity of piston ability freely.
