[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0028] Example 1

[0029] Reference Figures 1 to 6 The present embodiment provides a high-salt wastewater treatment device, including an evaporating tube 100, which is a horizontally placed hollow cylinder, and a heater is connected to the outside of the evaporating tube 100; a spiral cleaning mechanism 200, which includes a driving member 201 and a cleaning member 202, wherein the driving member 201 is connected to the axial center of the end of the outer wall of the evaporating tube 100, and the cleaning member 202 is arranged inside the evaporating tube 100, and the cleaning member 202 includes a spiral scraper 202a and a connecting plate 202b, and the spiral scraper 202a is spiral and made of spring steel.

[0030] A sewage inlet 101 and a steam outlet 102 are respectively provided at both ends of the top of the outer wall of the evaporating cylinder 100, and a first sewage outlet 103 is provided at one end of the outer wall of the evaporating cylinder 100 away from the driving member 201; the salt-containing wastewater enters the evaporating cylinder 100 through the sewage inlet 101, and the inside of the evaporating cylinder 100 is heated by the heater to evaporate the wastewater, wherein the steam is discharged through the steam outlet 102, and the evaporated salt is retained in the evaporating cylinder 100, and is discharged through the first sewage outlet 103 when the wastewater is completely evaporated.

[0031] The driving member 201 includes a servo motor 201a and a rotating shaft 201b. The servo motor 201a is arranged at the axis center of one end of the outer wall of the evaporating tube 100. The rotating shaft 201b is rotatably connected to one end of the outer wall of the servo motor 201a. The cross-sectional shape of the rotating shaft 201b is non-circular. The servo motor 201a enables the rotating shaft 201b to drive the cleaning member 202 to rotate inside the evaporating tube 100, thereby scraping off the salt particles on the inner wall of the evaporating tube 100.

[0032] There are two groups of connecting plates 202b, which are respectively fixedly connected to the two ends of the spiral scraper 202a. A connecting groove 202b-1 is opened at the axis center of the connecting plate 202b far away from the servo motor 201a of the two groups of connecting plates 202b, and the shape of the connecting groove 202b-1 corresponds to the cross-sectional shape of the rotating shaft 201b. The connecting plate 202b close to the servo motor 201a in the two groups of connecting plates 202b is fixedly connected at the outer wall of the rotating shaft 201b; through this arrangement, the connecting plate 202b far away from the servo motor 201a can slide along the rotating shaft 201b, and the salt particles stuck to the outer wall of the rotating shaft 201b can be removed by sliding of this group of connecting plates 202b.

[0033] The outer diameter of the spiral scraper 202a is the same as the inner diameter of the evaporation tube 100; since the spiral scraper 202a is spiral, when the spiral scraper 202a rotates, the scraped salt particles will be gradually transferred to one end of the evaporation tube 100 near the first sewage outlet 103 through the rotation of the spiral scraper 202a.

[0034] A positioning rod 202b-2 is provided on the outer wall of the spiral scraper 202a away from the servo motor 201a, and a spiral spiral groove 106 is opened on the inner wall of the evaporating tube 100, and the end of the positioning rod 202b-2 is slidably connected in the spiral groove 106; since the spiral groove 106 is spiral as a whole, when the two sets of connecting plates 202b rotate synchronously, since the positioning rod 202b-2 is slidably connected inside the spiral groove 106, the connecting plate 202b provided with the positioning rod 202b-2 will slide back and forth along the rotating shaft 201b, and the distance between the spiral scrapers 202a is controlled by the sliding of the rotating shaft 201b. When a large salt block appears inside the evaporating tube 100, the distance between the spiral scrapers 202a is contracted, thereby compressing and breaking the salt block, so as to prevent the large salt block from blocking the first sewage outlet 103.

[0035] A rotating cover plate 105 is rotatably connected to one end of the outer wall of the evaporating tube 100, and a second sewage outlet 105a is opened through the outer wall of the rotating cover plate 105; the position of the second sewage outlet 105a is controlled by rotating the rotating cover plate 105. When the second sewage outlet 105a and the first sewage outlet 103 overlap, the evaporating tube 100 is in an open sewage discharge state, and the salt particles are discharged by the rotating spiral scraper 202a.

[0036] A plurality of groups of legs 104 are disposed at the bottom of the evaporation cylinder 100 ; the legs 104 are used to support the evaporation cylinder 100 .

[0037] Working principle: When in use, the rotating cover plate 105 is rotated so that the first sewage outlet 103 and the second sewage outlet 105a do not overlap at all, so that the evaporation tube 100 is in a closed sewage discharge state, and the salt-containing sewage enters the evaporation tube 100 through the sewage inlet 101, and the inside of the evaporation tube 100 is heated by the heater to evaporate the wastewater, and the steam is discharged through the steam outlet 102, and the salt in the wastewater will be retained in the evaporation tube 100. At this time, the servo motor 201a drives the cleaning part 202 to rotate through the rotating shaft 201b, and the rotating spiral scraper 202a will scrape off the salt particles stuck on the inner wall of the evaporation tube 100. When the cleaning part 202 is rotating, since the connecting plate 202b is slidably connected with the inside of the spiral groove 106, the group The connecting plate 202b will slide back and forth along the rotating shaft 201b, and the salt particles adhering to the rotating shaft 201b will be scraped off by the sliding of the connecting plate 202b. The sliding of the connecting plate 202b will also compress and shrink the spiral scraper 202a to shorten the distance between the spiral scrapers 202a. When a large salt block appears inside the evaporating tube 100, the contracted spiral scraper 202a will break the salt block, and the large salt block will block the first sewage outlet 103. When evaporation is completely completed, the rotating cover plate 105 is rotated to make the second sewage outlet 105a coincide with the first sewage outlet 103, and the salt particles are pushed to the first sewage outlet 103 and discharged by the rotating spiral scraper 202a.

[0038] Among them, the heater and the servo motor are both relatively common existing technologies, so they will not be described in detail here.
