A kind of ultrasonic wave cleaning and filtrating equipment
Technical field
The utility model relates to a kind of filter, particularly a kind of ultrasonic wave cleaning and filtrating equipment.
Background technology
Organic matter, chloride are fallen in solid suspension and absorption that existing filter generally utilizes screen pack to remove in the water, water is entered by water inlet pipe, pass through screen pack with certain flow velocity, the water that obtains handling well from outlet pipe at last, solid suspension is then stayed on the screen pack, screen pack needs to change after using a period of time, wash by current usually, but the effect of cleaning is undesirable.
Summary of the invention
Screen pack cleans the above-mentioned technical problem that exists in the existing filter in order to solve, and the utility model provides a kind of simple in structure, ultrasonic wave cleaning and filtrating equipment that cleaning performance is good.
The technical scheme that the utility model solves the problems of the technologies described above is: comprise container, be provided with a screen pack in the container, the chamber wall of screen pack bottom is provided with water inlet pipe, the bottom of container is provided with blow-off pipe and ultrasonic unit, the chamber wall on screen pack top is provided with outlet pipe, scavenge pipe, and the top of container is provided with an overflow pipe.
Technique effect of the present utility model is: the utility model is when the cleaning and filtering net, the ultrasonic unit of container bottom can convert the electric energy of high frequency to mechanical oscillation, and be delivered in the interior water of container, the original not screen pack of easy cleaning is thoroughly cleaned, guarantee the filter quality of water, and solved the not problem of easy cleaning of screen pack.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Referring to Fig. 1, the utility model comprises container 1, be provided with a screen pack 3 in the container 1, the chamber wall of screen pack 3 bottoms is provided with water inlet pipe 2, the bottom of container 1 is provided with blow-off pipe 5 and ultrasonic unit 8, the chamber wall on screen pack 3 tops is provided with outlet pipe 7, scavenge pipe 6, and the top of container is provided with an overflow pipe.
Operation principle of the present utility model is: sewage process water inlet pipe 2 enters the contraminated zone below the container 1, after the water in the contraminated zone reaches certain capacity and pressure, by the filtration of screen pack, enter the clean water area above the container, the water of handling well at last flows out from outlet pipe 7.Solid suspension then stay screen pack below, use a period of time after, screen pack needs to clean.During cleaning, water flows into from scavenge pipe 6, and connection ultrasonic power, ultrasonic unit 8 converts the electric energy of high frequency to mechanical oscillation and is delivered in the container 1 in the water, vibration wave is according to the sine curve longitudinal propagation, a little less than the strong one deck of one deck, weak acoustic signals produces negative pressure to water body, makes to form small bubble in the water body, and strong acoustic signals produces malleation to water body, with the micro-bubble crushing that forms in the water body, the great shock wave of collapse of bubbles meeting produce power in the water body, shock wave cleans screen pack 3 and washes away, simultaneously, clear water in the scavenge pipe 6 also cleans and washes away screen pack 3, will and wash away the impurity that gets off and discharge through blow-off pipe 5 from screen pack 3 cleanings.
