Membrane switch/flexible circuit, conducting resinl, sensitive components etc..
At present to silver powder preparation method have liquid phase reduction, spray heating decomposition, electrolysis method, microwave plasma method,
Direct-current arc heat plasma method, mechanochemical synthesis, electron beam irradiation method etc..
The preparation of silver powder at present mainly uses liquid phase reduction, but during the preparation process due to the silver of chemical reaction generation
Particle surface can be higher, causes to generate reunion between super fine silver powder particle, forms bulky grain, only used when being cleaned with pure water it is mechanical or
Artificial stirring cannot completely effectively remove the organic or inorganic impurity wrapped up in agglomerated particle, cause the purity of silver powder decline from
And influence electric conductivity.
Summary of the invention
The purpose of this utility model provides precisely in order to overcome the problems, such as that silver powder of the existing technology cleaning is not thorough enough
A kind of high-efficient, at low cost device for the cleaning of liquid-phase reduction silver powder, to produce the performances such as good dispersion, electric conductivity ginseng
The excellent high dispersive silver powder of number.
The purpose of this utility model is achieved through the following technical solutions:
A kind of liquid-phase reduction silver powder cleaning device assisted with ultrasonic wave, including filter bucket, supersonic generator, described
It filters and is provided with fixed bracket on bucket, annular guide channel is provided on the fixed bracket, the diameter of the annular guide channel is greater than institute
State the diameter for filtering bucket；Sliding support is provided on the fixed bracket, the sliding support lower surface is provided with a 3 or more
Pulley, the position of the pulley are corresponding with the position of the annular guide channel；Vibrating head sliding slot is provided on the sliding support；
It is provided with sieve plate in the suction filtration bucket, filter cloth is provided on the sieve plate, the suction filtration bucket bottom is provided with drain
Mouthful；
It is provided with ultrasonic transducer on the vibrating head sliding slot, vibrating head, the vibration are provided on the ultrasonic transducer
Dynamic stick passes through the vibrating head sliding slot and protrudes into and filters in bucket；
The ultrasonic transducer is connect by conducting wire with supersonic generator.
The utility model has the advantages that
1, the utility model disperses agitation to the reduction silver powder filtered in bucket using microwave vibrations stick, can the effectively group of opening
Poly- silver powder particles and the organic or inorganic impurity for allowing pure water wash clean to be wrapped in silver powder avoid the purity decline of silver powder
And finally influence electric conductivity.
2, the back-and-forth motion by vibrating head in sliding groove and the rotation of Rotatable bracket combination, can make ultrasonic vibration stick
It realizes all standing to silver powder in bucket is filtered, does not stay dead angle.
3, since the distance between the filter cloth of bottom in vibrating head and suction filtration bucket is fixed, it is ensured that ultrasonic vibration stick is not
Filter cloth is damaged.
4, dispersion agitation is carried out to silver powder by mobile vibrating head, improves efficiency, eliminate manual agitation, improves
Product quality.
5, the utility model efficiently solves the cleaning Inclusion Problem of silver powder, and the silver of fine size, good dispersion is prepared
Powder.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the utility model sliding support top view；
In figure, 1- filters bucket, 2- sieve plate, 3- filter cloth, the fixed bracket of 4-, 5- sliding support, 6- pulley, 7- vibrating head, 8-
Ultrasonic transducer, 9- supersonic generator, 10- conducting wire, 11- vibrating head sliding slot, 12- annular guide channel, 13- leakage fluid dram.
Specific embodiment
The utility model is further described below according to attached drawing:
The reduction silver powder cleaning device assisted for ultrasonic wave such as Fig. 1 and as shown in Figure 2, including bucket 1 is filtered, sieve plate 2,
Filter cloth 3 is carried on a shoulder pole and is filtering the fixation bracket 4 with annular guide channel 12 on bucket, there is the sliding support 5 of vibrating head sliding slot 11 and pulley 6,
Insertion filters the vibrating head 7 in bucket 1, the ultrasonic transducer 8 to connect together with vibrating head 7, with conducting wire 10 and 8 phase of ultrasonic transducer
Supersonic generator 9 even, vibrating head sliding groove 11.After restoring silver powder and suction filtration bucket is added in pure water, shaken by vibrating head 7
The rotation combination of back-and-forth motion and sliding support 5 in dynamic stick sliding slot 11 can be such that ultrasonic vibration stick realizes to silver powder in suction filtration bucket
Effective Vibratory Mixing cleaning.
The course of work of the utility model is as follows:
1) silver powder just restored from reaction kettle is added in suction filtration bucket, pure water is then added.
2) the fixation bracket 4 with annular guide channel 12 and the sliding support 5 of vibrating head sliding groove 11 and pulley 6 will is put into pumping
On lauter tub 1, then the ultrasonic transducer 8 to connect together with vibrating head 7 is put into vibrating head sliding slot 11, adjusts good position ruler
It is very little, it is ensured that vibrating head 7 is without impinging on filter cloth.
3) it is powered to supersonic generator 9, and passes through back-and-forth motion and sliding support 5 of the vibrating head 7 in sliding groove
Cooperation carries out dispersion agitation cleaning 3 to 5 minutes to reduction silver powder in bucket 1 is filtered, cuts off the electricity of supersonic generator, use vacuum
Leach out the wash water filtered in bucket.
4) pure water is added again to the operation for filtering in bucket 1 and repeating the above third step, until the conductivity of wash water is small
In or be equal to 20 μ s/cm until.
5) ultrasonic transducer 8 to connect together with vibrating head 7 is taken away, the fixation bracket 4 with annular guide channel 12 is removed and is had
After the sliding support 5 of vibrating head sliding slot 11 and pulley 6, reduction silver powder is taken out in bucket 1 from filtering.
Vibrating head 7 and sliding support 5 make it in annular guide channel 12 and vibrating head sliding slot by operator's manual control
It is moved in 11.Vibrating head sliding slot 11 can guarantee that vibrating head 7 will not touch filter cloth 3, prevent from damaging.
