Detailed description of the invention
Preferred embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.
Embodiment
Diaphragm type hydraulic exciting single barrel vibrating mill, be made up of cylindrical shell 1, back-moving spring group 2, diaphragm type hydraulic vibration exciter 3, shock-absorbing spring group 4, base 5 and hydraulic means, diaphragm type hydraulic vibration exciter 3 is used to instead of general mechanical type vibrator, hydraulic means comprises switch valve 6, motor 7, liquid storage pool 8, liquor pump 9, conduit under fluid pressure 10, as shown in Figure 1.
From accompanying drawing 5, cylindrical shell 1 is formed by mill tube 1-1, side plate 1-2, base plate 1-3 consolidation, diaphragm type hydraulic vibration exciter 3 is by exciting plate one 3-1, exciting plate two 3-3 and film 3-2 is formed by connecting, i.e. exciting plate one 3-1, exciting plate two 3-3 is two stiffener plate be parallel to each other, film 3-2 is with non-leakage, the soft exciting plate material not easily extended is made, switch valve 6 is driven by motor 7, liquor pump 9 can be that self-contained motor 7 drives, the base plate 1-3 of cylindrical shell 1 and the upper plane Joint of exciting plate, film 3-2 and two exciting plate A ' in opposite directions, B ' face is tightly connected, can be bonding being tightly connected, as Fig. 2, also can be fixing being tightly connected of bolt presses, as Fig. 3, can also be only contact and to be unfixedly tightly connected.
A ', B ' face all can be divided into three regions, as Fig. 2: the region a contacted all the time with film 3-2, with film 3-2 discontiguous region b all the time, other region c, region a is not communicated with region b, film 3-2 is only connected with flat board at region a, film 3-2 and two exciting plates constitute a closed space, can free bend with the discontiguous part of two exciting plates, exciting plate arranges passage 3-4, thus the volume of this enclosure space is variable, this enclosure space is connected with switch valve 6 with liquor pump 9 by conduit under fluid pressure 10, switch valve 6 other end connects liquid storage pool 8, pump is feed fluid constantly, the liquid of enclosure space is periodically entered liquid storage pool 8 by switch valve 6.
Back-moving spring group 2 answers >=1 group, often group is by least 2 back-moving spring 2-3, 2-5, each 1 the reset pressing plate 2-2 in two ends, each 2 the nut 2-1 in two ends, a threaded rod 2-4 is formed, 2 back-moving spring 2-3, 2-5 is installed on outside two exciting plates by threaded rod 2-4 respectively, back-moving spring 2-3, 2-5 two ends respectively with exciting plate, reset pressing plate 2-2 contacts, threaded rod 2-4 is freely through back-moving spring 2-3, 2-5, corresponding hole on reset pressing plate 2-2 and exciting plate, nut 2-1 is arranged on the outer end of reset pressing plate 2-2 on threaded rod 2-4, threaded rod 2-4 bottom with the vibration damping pressing plate 5-1 of shock-absorbing spring group 5 above concrete mutually, back-moving spring 2-3 is made by regulating pretension, 2-5 is in pressured state all the time.
The effect of back-moving spring group 2 is when liquid in film increases or reduce, make two exciting plates of diaphragm type hydraulic vibration exciter 3 up and down apart from suitably increasing or resetting in time, namely in film liquid return to liquid increase before position, ensure that grinding machine is in and vibrates duty normally.
Shock-absorbing spring group 4 answers >=1 group, often group is made up of at least 1 shock-absorbing spring 4-2,1 vibration damping pressing plate 4-1,2 lead 4-3, lower seat 4-4, concrete mutually above threaded rod 2-4 one end and vibration damping pressing plate 4-1, plane is consolidated with lead 4-3 respectively for vibration damping pressing plate 4-1 lower plane and lower seat 4-4, shock-absorbing spring 4-2 is installed between vibration damping pressing plate 4-1 and lower seat 4-4 by lead 4-3, lower seat 4-4 and base 5 concrete mutually, base 5 is fixed on ground.The effect of shock-absorbing spring group 4 be can reduce system vibration to the transmission of ground, and reduce consequent noise.
In embodiment, reasonable design, the rigidity of adjustment back-moving spring 2-3,2-5 or the frequency of adjustment switch valve 6 can make system work under Near resonance oscillating state, thus the object reaching the large driving of small-power, reduce energy consumption, significantly improve efficiency.
Because film 3-2 makes with the material that not easily extends, so when liquid injection enclosure space, the pressure of film 3-2 internal liquid can change, and overcome the active force of back-moving spring 2-3,2-5 and other resistance makes the distance of two exciting plates increase; When valve is in opening state, under back-moving spring 2-3,2-5 effect, the liquid that the liquid of film 3-2 inside and pump export all will enter liquid storage pool 8 through valve, liquid pressure be declined, the distance of two exciting plates be reduced, thus completes a vibration cycles.The utility model is different from Normal hydraulic and pneumatic means: without the need to piston, thus there is not the sealing because piston causes, leakage, friction and wear.
Owing to not leaking, water can be used as medium.Enclosure space has very large work area, even if total so internal pressure little but vibration force can be very large, the Another reason that diaphragm type vibrator can be put to apply grinds with General Oscillation the situation requiring amplitude less to match.The cross section of the diaphragm type not edge in contact plate face is a semi arch, and its 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 enough little, current material just can meet the requirement of strength of pressure to film 3-2.The rotating speed changing switch valve 6 can change vibration frequency, and the flow changing pump can change amplitude.Therefore the utility model infinitely can not shut down Frequency And Amplitude Modulation, and Frequency And Amplitude Modulation has nothing to do.
Because the vibration force of diaphragm type vibrator and cylindrical shell 1 contact position is equally distributed, make system stress better; The relative motion of film 3-2 and two exciting plane is rolled and non-slip, so without friction and wear.Use thin material to manufacture diaphragm type, flexural fatigue can be reduced and damage.Because the vibration displacement of threaded rod 2-4 is directly proportional to the of poor quality of upper and lower plastid, therefore configuration quality exactly, add the effect of shock-absorbing spring 4-2, just can make machine to the vibration interference on ground no better than zero.
