Description

Technical Field

[0001] The invention relates to the field of ultrasonic descaling, and in particular to an ultrasonic anti-scaling and descaling device for an evaporative heater. Background Art

[0002] Evaporative heaters use heat energy to convert liquids into gas. Usually, the heating medium (such as steam, hot water, thermal oil, etc.) transfers heat to the heated liquid, causing the liquid to reach boiling point and begin to evaporate and vaporize. In this process, the solvent in the liquid is continuously vaporized and removed, while the solute remains in the remaining liquid, thereby achieving concentration or separation of the solution.

[0003] In the process of descaling the evaporator heater, ultrasonic cleaning is usually used. After ultrasonic cleaning, the cleaned dirt needs to be collected. The thickness of the dirt generated on the inner wall is different. The existing cleaning device solves the problem of cleaning the dirt, but does not take into account the thickness of the dirt at different positions, which results in the dirt not being completely cleaned.

[0004] Therefore, we have made improvements to this problem and proposed an ultrasonic anti-scaling and descaling device for an evaporative heater. Summary of the invention

[0005] The technical problem to be solved by the present invention is: how to remove the dirt on the inner wall of the infusion tube;

[0028] The cleaning mechanism includes a first slider 107, the upper end of which is connected to a scraper 109, the scraper 109 is flared, the upper surface of the first slider 107 or the scraper 109 is connected to the lower end of a telescopic rod 114, and the upper end of the telescopic rod 114 is fixedly connected to the first filter plate 102;

[0029] The conveying structure includes a second slider 110, a threaded piece 111 is fixedly connected to the outer surface of the second slider 110, the threaded piece 111 abuts against the infusion tube 103, a plurality of sound transmission holes 112 are arranged in a circular array on the outer surface of the second slider 110, and a wave spring 113 is fixedly connected between the first slider 109 and the second slider 110.

The bidirectional thread screw has two threads with opposite rotation directions, which respectively cooperate with the internal threads of the two sliders, thereby driving the first slider 107 and the second slider 110 to move towards each other. The scraper 109 on the first slider 107 abuts against the inner wall of the infusion tube 103. When the first slider 107 moves, the scraper 109 fixed at its upper end moves downward. During the movement, the scraper 109 always fits against the inner wall of the infusion tube 103. In addition, the scraper The plate 109 is made of a flexible plastic material, and can protect the infusion tube 103 during the scraping process, thereby cleaning the residual dirt on the inner wall of the infusion tube 103.

The wave spring 113 connected between the first slider 109 and the second slider 110 is used to limit the first slider 109 and the second slider 110. In addition, when the first slider 109 moves downward, the telescopic rod 114 on its upper surface simultaneously extends vertically downward. During the extension process, the first slider 109 can be ensured to move in a straight line during the sliding process, preventing it from abutting and squeezing during the opposite movement, and detaching from the screw rod 106 during the reverse movement.

The ultrasonic generator 202 is used to generate sound waves to descal the infusion tube 103. The reduction motor 203 fixedly connected to the lower end of the screw rod 106 is used to drive the screw rod 106 to rotate, so that the first slider 107 and the second slider 110 slide towards each other.

[0035] The limiting ring 401 sleeved on the output end of the reduction motor 203 is used to connect the reduction motor 203 and the cleaning plate 402. The cleaning plate 402 fixedly connected to the outer surface of the limiting ring 401 can scrape the generated dirt along the third filter plate 302 and discharge the dirt along the discharge port 303.

[0039] The support frame 601 sleeved on the outer surface of the sealed tank 501 is used to support the sealed tank 501. The first air pipe 602 connected to the outer surface of the sealed tank 501 inputs the preheated steam into the heating tank 603 for heating. The second air pipe 604 connected to the outer surface of the heating tank 603 is used to transport the heated steam to the compressor 605 for compression. The compressor 605 connected to the other end of the second air pipe 604 can preheat the infusion tube 103 inside the sealed tank 501 with the generated steam.

[0042] A plurality of through holes 81 are disposed on the outer surface of the scraper 109 . The scraper 109 is arc-shaped and abuts against the inner wall of the infusion tube 103 .

[0043] The through hole 81 arranged on the outer surface of the scraper 109 is used to allow the raw material liquid to enter the interior of the infusion tube 103 along the through hole 81. The raw material liquid passes through the first filter plate 102, the second filter plate 105, and the third filter plate 302 in sequence for three-stage filtration.

[0045] After the evaporation of the raw material liquid is completed and the dirt attached to the inside of the infusion tube 103 is removed, the reduction motor 203 is driven to drive the screw rod 106 to rotate. When the screw rod 106 rotates, the thread of the screw rod 106 adopts a bidirectional thread design. The bidirectional thread screw has two threads with opposite rotation directions, which respectively cooperate with the internal threads of the two sliders, thereby driving the first slider 107 and the second slider 110 to move towards each other. The scraper 109 on the first slider 107 abuts against the infusion tube 103. When the first slider 107 moves, the scraper 109 fixedly connected to its outer surface moves downward. During the movement, the scraper 109 is always in contact with the inner wall of the infusion tube 103.
