Description
Technical field
The utility model relates to the ultrasonic powder transfer device of a kind of ultrasonic travelling wave type.
Background technology
The comparative maturity that traditional powder conveying machinery has developed, but, make that powder conveying machinery volume is big because the actuator of traditional powder conveying machinery all adopts electromagnetic machine, the noise height, precision is low, only the big powder conveying of the amount of being suitable for.Along with the development of the high development and the progress of science and technology, particularly brand-new material of producing, a new height has been brought up in the requirement of powder conveying: miniaturization and high precision.The powder conveying machinery that utilization ultrasonic vibration principle is developed is compared with traditional powder conveying machinery, and concrete structure is simple, compact, carries the control accuracy height, and noise is little, responds characteristics such as fast.Therefore, exploitation ultrasonic travelling wave type powder conveying machinery can satisfy the new demand to powder conveying, can be widely used in industrial circles such as food, chemical industry, pottery, medicine.See the report of the research of the relevant principle of work of Japan in recent years, but do not seen the structure of concrete device and the effect of operation.
The utility model content
The purpose of this utility model be to provide a kind of have simple in structure, the operation noiseless, the control accuracy height, be very suitable for a small amount of or micro-powder material accurately, quantitatively carry, be applicable to food, medical treatment, chemical industry, pottery, etc. the novel powder feedway that presses for of industrial circle.For achieving the above object, traveling wave type ultrasonic powder transfer device of the present utility model, comprise base, hopper, delivery pipe, be characterized in that piezoelectric element and electrode place between two block pressur plates by bolt to clamp and connect the formation transfer unit with the discharge end of delivery pipe.
Traveling wave type ultrasonic powder transfer device of the present utility model is compared with existing relevant technology, have simple in structurely, compact, volume is little, noiseless, can accuracy control operational throughput, be specially adapted to powder material in the industrial circles such as food, medicine, chemical industry, pottery accurately, quantitatively carry.

Label title among Fig. 1: 1, base; 2, hopper; 3, delivery pipe; 4, piezoelectric element; 5, bolt; 6, pressing plate.
Label title among Fig. 2: wherein the title of 3,4,5,6, four labels is consistent with label title among Fig. 1, is respectively delivery pipe, piezoelectric element, bolt, pressing plate; 7, electrode; 8, nut.
The specific embodiment
Narrate the specific embodiment of the present utility model with reference to the accompanying drawings.Fig. 1 is a concrete structure, and promptly hopper 2 places on the base 1, and delivery pipe 3 is connected in hopper 2, and piezoelectric element 4 places between two block pressur plates 6 and clamps the discharge end that is connected in delivery pipe 3 with bolt 5.Fig. 2 has represented the constituent relation of delivery pipe and piezoelectric element, promptly two spheroidal piezoelectric ceramic pieces 4 place respectively between the copper electrode 7, with nut 8 piezoelectric ceramic piece and copper electrode clamping are connected in delivery pipe 3 discharge ends by the bolt 5 that is symmetrically distributed with two circular organism glass pressing plates 6.This device utilizes the unilateral internal diameter of piezoceramic to the decay row ripple that stretching vibration evokes in delivery pipe, and powder is carried.Wherein piezoelectric ceramic piece is a radial extension vibration mode attitude of utilizing the interior axis symmetry of face of spheroidal piezoelectricity ceramics, is designated as (R, 1) modal vibration, and R represents pure radial extension vibration mode attitude, and the exponent number of the pure radial extension vibration mode attitude of 1 expression is 1 rank.For enough vibrational energies are provided, select the vibration source of two piezoelectricity ceramics for use as the exciting powder transfer device, when applying identical high frequency electrical signal for these two piezoelectric ceramic pieces, they will evoke frequency same phase identical mechanical ripple in delivery pipe.According to theory of oscillation, after these two frequency same phase identical mechanical ripples superpose as can be known, its frequency and phase invariant, but its amplitude is two wave amplitude sums.
For the phase place of the voltage that guarantees two piezoelectric ceramic pieces of excitation is consistent with frequency, a slice electrode grounding in the middle of the piezoelectric ceramic piece, both sides two plate electrodes all connect the positive pole of voltage.Piezoelectric ceramic piece is polarized to full electrode along thickness direction.
For can make piezoelectric ceramic piece can with the delivery pipe closed contact, with two piezoelectric ceramic pieces and delivery pipe Bolt Connection, adopt the bolt that is symmetrically distributed that the predetermincd tension that is applied on the piezoelectric ceramic piece is evenly distributed with the organism glass pressing plate with eight symmetrical distributions.Owing to mainly utilize the axisymmetric pure radial expansion vibration of piezoelectric ceramic piece, vibration on other directions of piezoelectric ceramic piece is little to the influence of feedway, and the predetermincd tension that is added in like this on the direction of piezoelectric ceramic piece Surface Vertical can not exert an influence to the mode of operation of piezoelectric ceramic piece.
As the traveling wave type ultrasonic powder transfer device, delivery pipe is the vitals of whole device, for this reason, should adopt energy absorbing to ripple by the big material of coefficient, as organic glass tube.Delivery pipe is divided into transportation section and feed zone two parts.
