Embodiment
The preferred embodiment that the invention will now be described in detail with reference to the accompanying drawings.
Embodiment
Diaphragm type hydraulic exciting dual-drum vibration mill is by upper shell 1, back-moving spring group 2, diaphragm type hydraulic vibration exciter 3, lower cylinder Body 4, shock-absorbing spring group 5, base 6 are constituted, and hydraulic means includes switch valve 7, motor 8, liquid storage pool 9, liquid pump 10, hydraulic tube Road 11, general mechanical vibrator is instead of with diaphragm type hydraulic vibration exciter 3.As shown in Figure 1.
From accompanying drawing 5, upper shell 1, lower shell 4 are formed by mill tube 1-1, side plate 1-2, bottom plate 1-3 consolidations respectively, can be with It is symmetrical above and below.Upper shell 1, diaphragm type hydraulic vibration exciter 3, lower shell 4 are set gradually in vertical direction;
Diaphragm type hydraulic vibration exciter 3 is formed by connecting by the 3-1 of exciting plate one, the 3-3 of exciting plate two and film 3-2, i.e., exciting plate, It is two exciting being parallel to each other plates, film 3-2 is made of soft exciting plate material that is non-leakage, being difficult to extend, switch valve 7 Driven by motor 8, liquid pump 10 can be that self-contained motor 8 drives, the bottom plate 1-3's and the 3-1 of exciting plate one of upper shell 1 is upper flat The lower plane Joint in face, the bottom plate 1-3 of lower shell 4 and the 3-3 of exciting plate two, film 3-2 and opposite A ', B ' face of two exciting plates It is tightly connected, can is being tightly connected for bonding, what such as Fig. 2 or bolt, flange screw were fixed is tightly connected, and such as schemes 3, it can also be only contact and unfixed be tightly connected;
A ', B ' face can be divided into three regions, such as Fig. 2:The region a contacted all the time with film 3-2;Begin with film 3-2 Whole discontiguous region b, other region c, region a are not connected with region b, and film 3-2 is only connected in region a with flat board, film 3-2 and two exciting plates constitute one closing space, with the two discontiguous parts of exciting plate can with free bend so that this The volume of closing space is variable.The 3-1 of exciting plate one or the 3-2 of exciting plate two are provided with passage 3-4, and confined space passes through passage 3-4 connects the hydraulic power source of the exportable periodically variable liquid stream in direction.This closing space passes through hydraulic pipeline 11 and liquid Body pump 10 is connected with switch valve 7, and the other end of switch valve 7 connection liquid storage pool 9, pump is continually provided liquid, and switch valve 7 is periodically The liquid of closing space is discharged into liquid storage pool 9.
Back-moving spring group 2 should >=1 group, every group by least two back-moving spring 2-3,2-5, each 1 reset pressing plate 2-2 in two ends, Each 2 nut 2-1 in two ends, a threaded rod 2-4 composition, 2 back-moving springs 2-3,2-5 are respectively arranged in by threaded rod 2-4 On the outside of two exciting plates, back-moving spring 2-3,2-5 two ends are in contact with exciting plate, reset pressing plate 2-2 respectively, and threaded rod 2-4 is certainly By ground through corresponding hole on back-moving spring 2-3,2-5, reset pressing plate 2-2 and exciting plate, nut 2-1 is arranged on threaded rod 2-4 The upper outer end for resetting pressing plate 2-2, threaded rod 2-4 bottom and concrete mutually above the vibration damping pressing plate 5-1 of shock-absorbing spring group 5, lead to Overregulating pretension makes back-moving spring 2-3,2-5 be in pressured state all the time.
The effect of back-moving spring group 2 is when liquid is increased or decreased in film so that the two of diaphragm type hydraulic vibration exciter 3 Distance suitably increase or reset in time, i.e., the position that liquid is returned to before liquid increase in film, ensure grinding machine above and below exciting plate In normal vibration working condition.
Shock-absorbing spring group 5 should be >=1 group, and every group by least one shock-absorbing spring 5-2,1 vibration damping pressing plate 5-1,2 leads 5-3, a lower seat 5-4 composition, such as Fig. 4, threaded rod 2-4 one end and concrete mutually above vibration damping pressing plate 5-1, shock-absorbing spring 5-2, subtract Shake and be consolidated with lead 5-3 respectively in plane on pressing plate 5-1 lower planes and lower seat 5-4, shock-absorbing spring 5-2 passes through lead 5-3 It is installed between shock-absorbing spring 5-2 vibration damping pressing plate 5-1 and lower seat 5-4, lower seat 5-4 and the concrete mutually of base 6, base 6 are fixed on On ground.The effect of shock-absorbing spring group 5 is can to reduce transmission of the vibration to ground of system, and reduces resulting make an uproar Sound.
The frequency of embodiment reasonable design, adjustment back-moving spring 2-3,2-5 rigidity or adjustment switch valve 7 can make System works under Near resonance oscillating state, so as to reach the big driving of small-power, reduce energy consumption, put forward efficient purpose.
Because film 3-2 is made of the material for being difficult elongation, so when liquid injects closing space, film 3-2 The pressure of internal liquid can change, and overcome back-moving spring 2-3,2-5 active force and other resistances to make the distance of two exciting plates Increase;When valve is in opening state, under back-moving spring 2-3,2-5 effect, the liquid of liquid and pump output inside film 3-2 Liquid storage pool 9 all will be entered through valve, decline liquid pressure, reduce the distance of two exciting plates, so as to complete a vibration cycles. What the present invention was different from Normal hydraulic and pneumatic means is:Without piston, thus in the absence of caused by piston seal, leak, Friction and wear.
Due to not leaking, water can be used as medium.Closing space has very big work area, even if so internal The little but total vibration force of pressure can be very big, and another reason for diaphragm type vibrator can be put to and apply is and General Oscillation Mill requires that the less situation of amplitude matches.The section that diaphragm type does not contact the edge of plate face is a semi arch, and it is maximum Radius R is slightly larger than exciting amplitude.
The stress of thin-film material is directly proportional to internal pressure and arc radius, as long as therefore arc radius is sufficiently small, current material is just Intensity requirement of the pressure to film 3-2 can be met.Vibration frequency can be changed by changing the rotating speed of switch valve 7, change the stream of pump Amount can change amplitude.Therefore the present invention can not infinitely shut down Frequency And Amplitude Modulation, and Frequency And Amplitude Modulation is unrelated.
Because the vibration force of diaphragm type vibrator and cylinder contact position is equally distributed so that system stress compared with It is good;The relative motion of film 3-2 and two exciting planes is to roll and non-slip, so without friction and wear.Use thin material Diaphragm type is manufactured, flexural fatigue damage can be reduced.Due to threaded rod 2-4 vibration displacement and plastid up and down it is of poor quality into just Than therefore configuration quality exactly, along with shock-absorbing spring 5-2 effect, so that it may so that machine to the vibration interference on ground almost Equal to zero.
