Description
1, technical field
The present invention relates to the efficient sifting vibrating sieve of the inside and outside screen frame of a kind of monoblock type.
2, background technology
The structure that existing ultrasonic vibration commonly used is sieved has two kinds:
A kind of structure is as shown in Figure 1, generally comprises screen frame 01, is located at the screen cloth that has mesh 02 on the screen frame 01 and is located at the ultrasonic vibration 03 of screen cloth 02 central authorities, and ultrasonic vibration 03 is provided with and power supply wire connecting 04.There is following defective in this ultrasonic vibration screen cloth when the filtering screening electrostatic powder: 1, because ultrasonic vibration head and connected electric wire expose above screen cloth; So when the filtering screening electrostatic powder; Ultrasonic vibration head and connected electric wire can be covered by powder, not easy to clean; 2, the ultrasonic vibration head can generate heat in the course of the work, causes electrostatic powder to solidify inefficiency; 3, the ultrasonic vibration head has constant weight, and it directly is carried in screen cloth central authorities, and when the ultrasonic vibration head was worked, screen cloth was fragile.
Another kind of structure is as shown in Figure 2, generally comprises screen frame 01, is located at the screen cloth that has mesh 02 on the screen frame 01, and is fixed on the ultrasonic vibration 03 on the screen frame 01.There is following defective in this ultrasonic vibration screen cloth when the filtering screening electrostatic powder: 1, the ultrasonic vibration head acts directly on the screen frame 01, and screen frame 01 is heavier, and the vibrational energy loss is big, and vibration frequency is low, and filter screen efficient is not high.
Except that the defective that two kinds of ultrasonic vibrations commonly used sieves exist as previously mentioned, the defective that also has a maximum is that the cost of ultrasonic vibrator is than higher.
3, summary of the invention
The object of the present invention is to provide a kind of high efficiency, low cost of manufacture, be easy to clear up, the efficient sifting vibrating sieve of the inside and outside screen frame of the monoblock type of fragile screen cloth not when working.
The present invention realizes through following technical scheme scheme:
The efficient sifting vibrating sieve of the inside and outside screen frame of a kind of monoblock type comprises screen cloth and vibration head on screen frame, the screen frame, and described screen frame comprises outer ring, sympathetic response ring and connecting band; Outer ring and sympathetic response ring couple together through connecting band; Said vibration head is located at the outside of screen frame, and this vibration head is connected with one and passes the axle that shakes, and said outer ring is provided with an axis hole; Said sympathetic response ring is provided with connecting hole; The said biography axle that shakes inserts the connecting hole up to the sympathetic response ring in the axis hole of outer ring, and the end face that passes the axle that shakes is closely contacted under the effect of connecting bolt with the connecting hole end face, on the said sympathetic response ring screen cloth is installed.
Above-mentioned described outer ring, sympathetic response ring and connecting band are one-body molded.
Above-mentioned described connecting band is " Z " shape.
Above-mentioned described connecting hole is a stepped hole; Biography is shaken and is offered screwed hole on the axial end; Connecting bolt passes stepped hole and is screwed into the screwed hole that passes on the axial end of shaking from the inboard of sympathetic response ring, makes the end face that passes the axle that shakes with the closely contact under the effect of connecting bolt of stepped hole inner face.
The wall thickness of the connecting band between above-mentioned described outer ring and the sympathetic response ring is 0.2～2 millimeter.
Above-mentioned described biography is shaken and is provided with the vibration isolation cover between axle and the axis hole, and said vibration isolation cover is processed by nonmetallic materials.
Above-mentioned described said vibration head is gas vibrator vibration source or ultrasonic transducer vibration source.
Above-mentioned described screen cloth mesh pitch-row is 100～500 microns.
The present invention compared with prior art has following advantage: 1, screen frame of the present invention comprises outer ring, sympathetic response ring and connecting band, and outer ring and sympathetic response ring couple together through connecting band, and vibration head is located at the outside, screen frame outer ring; Be delivered to screen cloth to vibration through the sympathetic response ring, so when vibration head is worked, even its heating; Can not make the electrostatic powder curing on the screen cloth cause the screen cloth mesh to stop up high efficiency, compact conformation yet; The screen cloth dust is cleared up easily, low cost of manufacture; 2, hold together with the thin-walled connecting band between the sympathetic response ring of screen frame and the outer ring; Said biography is shaken and is provided with the vibration isolation cover that nonmetallic materials are processed between axle and the axis hole; These prevent that when guaranteeing the screen frame cramped construction vibration is delivered on the screen frame outer ring; Energy loss with minimum passes to vibration on the screen cloth, and screen cloth obtains maximum vibratory output, the power that output is maximum; 3, vibration head and screen cloth adopt to divide a body structure, the cleaning of screen cloth, change convenient, quick; 4, said outer ring is provided with an axis hole, and said sympathetic response ring is provided with connecting hole, and the said biography axle that shakes inserts the connecting hole up to the sympathetic response ring in the axis hole of outer ring; Connecting hole is a stepped hole; Biography is shaken and is offered screwed hole on the axial end, and connecting bolt passes stepped hole and is screwed into the screwed hole that passes on the axial end of shaking from the inboard of sympathetic response ring, and the end face that passes the axle that shakes is closely contacted under the effect of connecting bolt with the stepped hole inner face; Simple in structure, pass the axle that shakes and be connected tightr with the sympathetic response ring; 5, said vibratory sieve is applicable to gas vibrator vibration source and ultrasonic transducer vibration source simultaneously; The cost of gas vibrator is lower than the cost of ultrasonic transducer; In use various conditions is selected different vibration sources for use, and efficent use of resources is practiced thrift manufacturing cost greatly.6, the connecting band between above-mentioned described outer ring and the sympathetic response ring is " Z " shape, and wall thickness is 0.2～2 millimeter, and the vibration of sympathetic response ring is isolated by connecting band, is difficult to be delivered to the outer ring.
