Abstract
The utility model relates to an ultrasonic degassing device, comprising fluid degassing tanks and at least one ultrasonic vibrator. The fluid degassing tank is equipped with a de-aeration cavity inside. The ultrasonic vibrator is placed on the bottom of the fluid gas-separation tank, below the de-aeration cavity. Compared with the current technology, the utility model manages to degas the coating fluid and guarantee the quality of the coating fluid. The rejection rate of the coating production is rapidly reduced from three percent to zero point one percent. Economic results of the product are hence greatly improved.
Description
Technical field
The utility model relates to a kind of ultrasonic degas device.
Background technology
The fluid film coating technique is widely used in the production of numerous products, comprise printed circuit board, textile, various functional membrane, battery pole piece in the floppy disk of photosensitive drums, video and audio recording tape, computer of converted paper, functional paper, newsprint, packaging material, the duplicator of various grades and CD-ROM drive, the microelectronics industry, and silver salt, non-silver salt photosensitive material or the like, coating is one of technology of wherein most critical.
The preparation of fluid is the pith in the whole coating process.It has comprised the various unit operations before the coating, and as dissolving, stirring, conveying, filtration, the degassing, mixing, temperature control etc., these operations all have very big influence to the quality of final coated product.
All coating fluids all can dissolve certain gas in preparation, processing and course of conveying.When condition changes, when making gas surpass its solubility limit, will from solution, discharge the formation bubble.
The generation of microbubble and elimination in the fluid (i.e. the degassing) are the problems that the most generally occurs and must solve in the fluid film coating production process.The existence of microbubble can have a strong impact on the apparent mass of coated product, makes the surface of final products pin hole point, air line occur, and serious meeting large tracts of land occurs and lacks and to be coated with, and causes waste product.This patent proposes comprehensive solution at the microbubble problem in the coating fluid.
Existing coating fluid degassing technology generally adopts methods such as nature leaves standstill, decompression, centrifugal mechanical gas-liquid separation, bubble trap, but these technology all exist certain deficiency:
1. leave standstill naturally, method such as centrifugal mechanical gas-liquid separation, production process length consuming time is difficult for realizing serialization production;
2. methods such as decompression, centrifugal mechanical gas-liquid separation, bubble trap need be acquired some plant equipment, have increased the input of equipment, have also increased the probability that produces new bubble simultaneously;
More than several technology all can not remove microbubble in the fluid effectively.
The utility model content
The purpose of this utility model is that prior art is improved, and a kind of ultrasonic degas device is provided, and can remove the microbubble in the fluid effectively, and the technical scheme of employing is as follows:
Ultrasonic degas device of the present utility model is characterized in that: comprise fluid degassing tank and at least one ultrasonic oscillator, be provided with devolatilizing chamber in the fluid degassing tank, ultrasonic oscillator is located at fluid degassing tank bottom, is positioned at the devolatilizing chamber below.
Described ultrasonic oscillator frequency range is 25～50Hz, and power bracket is 100～1000w.
Separate with at least one baffle plate in the middle of the devolatilizing chamber of described fluid degassing tank,, improve degassing efficiency to prolong distance and the time that fluid passes through.
In order to control the pressure of fluid degassing tank inner air, the top of the devolatilizing chamber at fluid degassing tank top is provided with piezometry and adjusting device.
In order to understand and regulate the height of coating fluid in the devolatilizing chamber, the top of the devolatilizing chamber at fluid degassing tank top is provided with liquid level gauge.
In addition, be corroded in order to prevent the fluid degassing tank, and contaminated-fluid itself conversely, the fluid degassing tank is preferably rustless steel container.
In order to keep the temperature of coating fluid in the fluid degassing tank, also comprise controllable constant-temperature water-bath interlayer, controllable constant-temperature water-bath interlayer is located on the fluid degassing tank outer wall, can set required temperature arbitrarily in 20～80 ℃ of scopes, to adapt to the requirement of different coated products.
In addition, coating fluid-transporting tubing and each unit all adopt closed-loop operation, and system adopts the malleation design, infiltrate from the pipe fitting junction to prevent gas, avoid the generation of new bubble.
The utility model beneficial effect against existing technologies is, can reach the purpose of the coating fluid degassing comprehensively, guarantee the quality of coating fluid, reduce coating significantly and produce percent defective, make and produce percent defective and drop to approximately 0.1% from original about 3%, improve the economic benefit of product greatly.
