Description

A kind of new type ultrasonic wood chip washing machine

Technical field

The utility model belongs to slurrying industry chip washing technical field more particularly to a kind of new type ultrasonic chip washing Machine.

Background technique

Chip washing is the indispensable important step of slurrying industry material papering section.When material enters stock, bring big Mud, sand, stone, iron and the uncertain other materials of amount, in order to ensure the safe operation and product quality of downstream process equipment Stabilization.

The most widely used chip washing equipment of existing market, usually by body, rotary drum, water spout, precipitation tank, wood chip Slot, motor driven.Fin is provided on rotary drum, impurity has discharge port discharge, discharge outlet has dewatering spiral discharge.

Since it is cleared up the silt on wood chip using the collision between the collision friction and wood chip and rotary drum between wood chip, Therefore the drawbacks of this chip washing equipment application, is that, it cannot be guaranteed that wood chip cleans up completely, chip washing is inefficient, It cannot achieve comprehensive wood chip cleaning；And since the accumulation of organic matter and bacterium needs to carry out washing facility frequently to determine Phase cleaning；And scavenging period is long, generates a large amount of waste water.

Ultrasonic wave is a kind of sound wave of the frequency higher than 20000 hertz, its good directionality, penetration capacity is strong, is easily obtained Compared with the sound energy of concentration.Propagation distance in water farther out, can be used for ranging, test the speed, clean, welding, rubble, sterilization, disinfection etc..

Using the mechanism of ultrasonic wave, cavitation, fuel factor and chemical effect can carry out ultrasonic bonding, drilling, The crushing of solid, degassing, dedusting, removes bird nest, cleaning, sterilizing, promotes chemical reaction and carry out biological study at emulsification.In work Each department such as mining industry, agricultural, medical treatment, papermaking, slurrying has been widely used.

Ultrasonic wave principle when cleaning is to be converted into high-frequency by energy converter by supersonic generator high frequency oscillation signal Mechanical oscillation and travel to medium.The forward directed radiation of ultrasonic wave density interphase in cleaning solution, flows liquid in cleaning solvent And generate ten hundreds of minute bubbles.The micro-bubble (cavitation nucleus) being present in liquid vibrates under the action of sound field.Work as sound When pressure reaches certain numerical value, bubble generates shock wave when increasing then closure suddenly rapidly.Upper kilo-atmospheric pressure is generated around it Power (general to generate 1012-1013 megapascal).Insoluble dirt is destroyed, and is scattered in them in cleaning solution.Work as solid ion, quilt When greasy dirt is wrapped up in and is adhered to cleaning object surface in cleaning solution, oil is emulsified solid ion and is detached from.To reach cleaning materials Body surface face catharsis.

Using ultrasonic cleaning, generally there are two types of cleaning agents: chemical and aqueous cleaning agent.Cleansing medium is chemistry Effect, and ultrasonic cleaning is physical action, two kinds of effects are combined to carry out abundant, thoroughly cleaning to object.

The more altitude effect of the power density of ultrasonic wave is stronger, and speed is faster, and cleaning effect is better.The frequency of ultrasonic wave is got over Low, the cavitation generated in a liquid is easier, acts on also stronger.The high directivity of frequency height then ultrasonic wave, is suitable for fine Object cleaning.

In general ultrasonic wave is best in 30 DEG C -40 DEG C cavitation effects.Then the higher effect of temperature is more significant for cleaning agent.It is logical When normal practical application ultrasonic cleaning, the fast, high production efficiency using 40 DEG C -50 DEG C of operating temperature cleaning speeds.

If chip washing efficiency and effect can will be greatly promoted by ultrasonic applications in chip washing equipment.

A kind of new type ultrasonic wood chip washing machine, including body, the body upper are rectangular sink, and middle part is side Taper, by square cone, gradually transition is cross section is round infundibulate for bottom, and middle part and bottom constitute precipitation tank groove body 8；

And the feed inlet 1 at the top of body is located at organism bottom positioned at the discharge port 6 and water inlet pipe 4 of organism sidewall Sediment pot 7；Rotary drum 2 positioned at internal body middle and upper part has fin on rotary drum, and rotary drum successively connects with speed reducer and motor It connects；

It further include the supersonic generator 5 being set on body.

Residual cake valve 9 is arranged in 7 bottom of sediment pot and sediment pot 7 and body junction.

Supersonic generator used in the present embodiment be purchased from Wenzhou District of Zhejiang Province, model 3008B, use power for The supersonic generator of 300W or 600W, frequency 25kHz, 28kHz or 40kHz.Power supply is that AC220V individually powers.

The rotation counterclockwise of rotary drum 2.The water inlet pipe 4 and discharge port 6 on body are arranged oppositely.The water inlet pipe 4 Port connects nozzle, and nozzle is located at body upper, to 2 spray water of rotary drum.

As a typical embodiment, the supersonic generator is five, wherein four supersonic generators are located at Same level is uniformly distributed on precipitation tank, is located in sink there are one supersonic generator, and the ultrasonic wave occurs Device includes ultrasonic probe.

3 be liquid level in figure, and the discharge port and water outlet of rinsing maching are one, and the wood chip and water after washing are arranged by discharge port Out.

In order to enhance ultrasonic effect, can be reflected back since ultrasonic wave encounters metal ion, in ultrasonic wave wood chip washing machine, Xian Di slot area underwater, until to precipitation tank along four angles, the inclination installation one on the square face of sink and precipitation tank intersection The ultrasonic reflections plate 10 of the wide 5-8cm of item or make counterpunch board, the ultrasonic reflections plate 10 is 304 stainless using 1cm thickness Rinsing maching is divided into four open regions, ultrasonic probe is located at each using the corner angle of the precipitating groove body of square cone by steel plate In a region.

The horizontal tilt angle range of the ultrasonic reflections plate 10 is 10-30 degree.

When ultrasonic wave work, after sound wave encounters reflecting plate, horse back meeting bounce back, the regular movement of stroke, favorably It is washed in material.Advantageous sediment precipitates rapidly along defined route.

The fixed form of supersonic generator are as follows: 1, first by wood chip washing machine, between precipitation tank and sink, open One hole identical with supersonic generator probe size, and probe base is installed, then probe is inserted into inside rinsing maching, It is required that length must not exceed 2 centimeters, because too long be easily damaged.Then it is fixed with screw bolt.2, when ultrasonic probe is installed Afterwards, after phenomena such as determination is not leaked electricity, leak, probe is connected with ultrasonic control system, both can be used, it is big according to production capacity Small, power and frequency size are adjustable.

A kind of operating principle of new type ultrasonic wood chip washing machine provided by the utility model are as follows:

1, the theory of mechanics of wood chip washing machine is utilized.When wood chip, which enters, washes wood chip sink, under the rotation of rotary drum, utilize The pressure of fin and water spout on rotary drum is back and forth stirred wood chip, and the substance that specific gravity sinks is deposited to deslagging by natural-drop In tank.

2, using five supersonic generators being placed on the sink and precipitation tank of washing wood chip, wood chip is carried out complete The cleaning in orientation.

3, it is acted on using ultrasonic cavitation:

Cavitation forms or keeps stable single vibration, generates a large amount of minute bubbles in a liquid.One the reason is that liquid There is tensile stress and forms negative pressure in interior part, the original bubble saturation of the reduction of pressure.Surrounding liquid pours bubble suddenly when vanishing It generates high temperature, high pressure and generates shock wave simultaneously, the interior friction accompanied with cavitation can form uniform cleaning to wood chip.
