[0002] Hydrophobic expansion tanks are key equipment in thermal systems and are widely used in power plants, industrial boilers, and other scenarios. Their core function is to receive system condensate, reduce pressure and expand capacity to allow the condensate to flash evaporate, and separate secondary steam for recycling. However, in the use of existing hydrophobic expansion tanks, the condensate inside may crystallize, which may cause blockage. At the same time, crystallization may lead to equipment damage and reduce the service life of the device.

The beneficial effect of this utility model is"; however, during the use of this hydrophobic expansion tank, the hydrophobic material processed inside may crystallize during the processing. The crystals generated during processing may block the channels between the hydrophobic pipes and the inside of the tank, resulting in obstructed hydrophobic drainage. At the same time, the crystal particles may wear down equipment parts, aggravate equipment wear, and reduce the service life of the device. Utility Model Content

[0020] In this embodiment, as Figure 2 As shown, the hydrophobic expansion tank body 11, together with the first ultrasonic generator 13 and the second ultrasonic generator 14, forms an ultrasonic anti-crystallization structure.

[0021] In this embodiment, as Figure 3 As shown, the hydrophobic expansion tank body 11 and the filter chamber 22 are connected by the first connecting pipe 12 and the second connecting pipe 21 to form a fixed connection structure.

[0024] The computer software involved in the hardware carriers such as hydraulic cylinders in the technical solution is software technology known to those skilled in the art. It is merely applied to the aforementioned hardware carriers. In other words, the computer software portion of the technical solution is an essential technical feature for solving the aforementioned technical problem, constituting a necessary technical feature for the technical problem solved by this application, but it is not a differentiating technical feature or a point of technical improvement. The applicant has not made any technical improvements to the computer software portion involved in the aforementioned related hardware carriers, nor is it a key technical point of the invention.

[0025] Therefore, the "hydraulic cylinder," "ultrasonic generator," etc. involved in this application are physical functional modules that combine computer software programs or protocols in the prior art with the hardware carrier of this application. The computer software programs involved in these physical functional modules are all technologies known to those skilled in the art and are not improvements of this application. The improvement of this application should be the interaction relationship between the various physical functional modules, that is, the improvement of the overall structure of the automatic dipping machine of this application, so as to solve the corresponding technical problems to be solved by this application.

[0026] The working process of this anti-crystallization hydrophobic expansion tank is as follows: First, the user needs to place the hydrophobic expansion tank assembly 1 inside the frame 31. Then, the user only needs to start the hydraulic cylinders 33 fixedly installed on both sides of the frame 31 through the external electrical control. The hydraulic cylinders 33 will push the push rod 34 slidably installed inside the hydraulic cylinder 33 and the clamping plate 35 fixedly installed at one end of the push rod 34. Together with the support block 15 fixedly installed at the bottom of the hydrophobic expansion tank body 11, a clamping and fixing structure is formed. After the clamping and fixing is completed, the user can fix the filter assembly 2 to one end of the first connecting pipe 12 with screws and nuts to form a fixed connection structure.

[0027] After installation, the user can transport the condensate to the filter chamber 22 through the second connecting pipe 21. The limiting groove 23 fixedly installed inside the filter chamber 22, together with the first fixing plate 24, can fix the screen 25. The first fixing plate 24 and the screen 25 work together to filter out the condensate impurities inside the filter chamber 22. The filtered condensate will be transported to the condensate expansion tank body 11 through the second connecting pipe 21 at the other end.

[0028] During use, to prevent hydrophobic crystals from forming inside the device, the user can use an external electrical control to activate the first ultrasonic generator 13 fixedly installed on both sides of the hydrophobic expansion box body 11 and the second ultrasonic generator 14 fixedly installed at the bottom of the hydrophobic expansion box body 11 to achieve ultrasonic cleaning of hydrophobic crystals inside the hydrophobic expansion box body 11.

[0029] If the user needs to replace or repair the device, the user can use an externally connected electronic control system to control the hydraulic cylinder 33, which, in conjunction with the push rod 34, will allow the clamping plate 35 to be removed from the groove on the outer surface of the support block 15, thus achieving quick disassembly.

[0030] Among them, the first ultrasonic generator 13 and the second ultrasonic generator 14 are of model USGG10, and the hydraulic cylinder 33 is of model CX-SD.
