Description

Technical Field

[0001] This application relates to the field of flash evaporation equipment technology, and more specifically, to a flash evaporation foam trapping and crystal removal device with a self-cleaning function. Background Technology

[0002] Flash evaporation is a process in which a pressurized, high-temperature liquid is rapidly depressurized to reach its boiling point, thereby producing partial vaporization and achieving gas-liquid separation. As a key piece of equipment for realizing this process, flash tanks are widely used in many fields such as chemical, food, and pharmaceutical industries.

[0003] Currently used flash tanks often lack self-cleaning functions in their internal wire mesh demisters. This leads to sluggish demister removal on the surface during long-term use, causing blockages and severely affecting the flash tank's flashing effect and the stability of continuous operation.

[0004] To address the aforementioned issues, this application provides a flash evaporation de-icing device with a self-cleaning function. Utility Model Content

[0006] A flash evaporation de-icing device with self-cleaning function includes a flash tank, wherein a wire mesh demister is provided inside the upper side of the flash tank, and a de-icing component is provided above the wire mesh demister.

[0007] The defoaming assembly includes a rotating seat located inside the flash tank. A groove is embedded in the outer wall of the rotating seat's center. Multiple limiting shafts are circumferentially and evenly slidably fitted onto the inner wall of the groove. The ends of these limiting shafts away from the groove are fixedly connected to the inner wall of the flash tank. A gear ring is located above the rotating seat. Four fixed arc plates are circumferentially and evenly fixedly connected to the bottom of the gear ring. The bottoms of these four fixed arc plates are fixedly connected to the top plane of the rotating seat. A gear meshes with one side of the inner end of the gear ring. The top of the gear is connected to a drive shaft. The rotating base has a central shaft fixedly connected to its inner wall. A trapezoidal scraper is fixedly sleeved at the bottom end of the central shaft. Both the trapezoidal scraper and the central shaft are hollow structures that are connected to each other. The bottom of the trapezoidal scraper is close to the surface of the wire mesh demister. Multiple through holes are linearly and evenly opened on one side of the trapezoidal scraper. A vertical tube is fixedly sleeved at the center of the top of the central shaft. An L-shaped tube is rotatably sleeved at the upper end of the vertical tube. The L-shaped tube passes through one side of the upper end of the flash tank. A pump is installed on the side of the L-shaped tube near the outer wall of the flash tank.

[0008] Furthermore, a positioning plate is fixedly installed on the upper surface of the drive motor, and one side of the positioning plate is fixedly connected to the inner wall of the flash tank.

[0009] Furthermore, a first sealing ring is fixedly fitted onto the inner wall of the upper end of the vertical pipe, and the inner wall of the upper end of the vertical pipe is in rotatable contact with one side end of the L-shaped pipe through the first sealing ring.

[0010] Furthermore, the top of the flash tank is fixedly fitted with a liquid inlet, and the bottom of the flash tank is fixedly fitted with a liquid outlet and a crystal outlet on both sides, respectively. The lower outer wall of the flash tank is uniformly fixedly connected with four support legs.

[0011] Furthermore, the inlet, outlet, and crystal discharge port are all fixedly fitted with flanges at the ends facing away from the flash tank, while a valve is provided on the side of the outlet closest to the flash tank.

[0012] Furthermore, a steam outlet is fixedly fitted onto one side of the upper end of the flash tank, and an installation sleeve is movably fitted onto the outer wall of one side of the steam outlet. A second sealing ring is fixedly installed on the inner wall of the installation sleeve, and the inner wall of the installation sleeve slides in contact with the outer surface of the steam outlet through the second sealing ring. A filter cylinder is fixedly connected to one end of the installation sleeve, and the outer end of the middle part of the installation sleeve is fixedly installed on one side of the steam outlet by three evenly distributed mounting screws.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] In this application, the demisting assembly installed on the wire mesh demister allows for the effective improvement of the demisting rate and effect on the surface of the wire mesh demister in the flash tank through the combined action of the rotating seat, ring groove, limiting shaft, gear ring, fixed arc plate, gear, drive motor, central shaft, vertical pipe, L-shaped pipe, extraction pump, trapezoidal scraper, and through hole. This prevents the surface from experiencing demisting stagnation or blockage, thus avoiding any impact on the flashing effect and continuous operation stability of the flash tank itself.

The setting of the first sealing ring can ensure the contact sealing effect of the two at the rotatable position without hindering the rotational engagement state between the vertical tube 10 and the L-shaped tube 11.

[0026] A liquid inlet 15 is fixedly fitted to the top of the flash tank 1, and a liquid outlet 16 and a crystal discharge port 17 are fixedly fitted to both sides of the bottom of the flash tank 1, respectively. Four support legs are evenly fixedly connected to the lower outer wall of the flash tank 1.

[0028] The implementation principle of this embodiment is as follows: During use, the drive motor 8 drives the gear 7 to rotate, and the gear 7 meshes with the inner end of the gear ring 5, causing the gear ring 5 to rotate. At the same time, each fixed arc plate 6 drives the rotating seat 2 to rotate. During the rotation of the rotating seat 2, it is in a limited rotational sliding engagement with each limiting shaft 4 through the ring groove 3. Simultaneously, the central shaft 9, vertical pipe 10, and trapezoidal scraper 13 rotate, thereby accelerating the demisting work on the surface of the wire mesh demister through the trapezoidal scraper 13. And because the upper end of the vertical pipe 10 and the L-shaped... Under the rotational action of the tube 11, the vertical tube 10 can maintain communication with the L-shaped tube 11 during its passive rotation. When the pump 12 is started, the L-shaped tube 11 forms a negative pressure suction force on the interior of the vertical tube 10, the central shaft 9, and the trapezoidal scraper 13. At the same time, the multiple through holes 14 on one side of the trapezoidal scraper 13 work together to achieve the scraping and adsorption removal of dandruff on the surface of the wire mesh demister. This achieves the self-cleaning function of the wire mesh demister inside the flash tank 1, thereby improving the dandruff rate and effect on the surface of the wire mesh demister.

[0029] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
