[0041] like Figure 6 and Figure 8 As shown, the salt collecting assembly 4 includes a connecting plate 401 and a collecting ring 403, one side of the long arm end of the connecting plate 401 is fixedly connected to the arc surface of the rotating shaft 306, the outer wall of the collecting ring 403 is fixedly connected to the inner wall of the tank body 1, and one side of the short arm end of the connecting plate 401 is fixedly connected with a scraper 402, the lower surface of the scraper 402 is fitted with the upper surface of the collecting ring 403, the upper surface of the collecting ring 403 is provided with a groove 405, the inner wall of the groove 405 is fitted with a scraper ring 408, the outer wall of the tank body 1 is provided with a discharge hole 406, and the inner wall of the discharge hole 406 is fitted with a sealing plate 407, one side of the sealing plate 407 is fixedly connected to one side of the outer wall of the scraper ring 408. When the scraper 311 scrapes out the crystallized salt on the inner wall of the tank body 1, the crystallized salt will fall on the upper surface of the aggregate ring 403. At this time, the rotation of the rotating shaft 306 will drive the connecting plate 401 to rotate, and the connecting plate 401 will drive the scraper 402 to move along the upper surface of the aggregate ring 403, so that the crystallized salt on the scraper 402 can be scraped into the groove 405.

The output end of the electric push rod 410 is fixedly connected to the side of the sealing plate 407 away from the scraper ring 408. When it is necessary to regularly collect the crystallized salt into the collecting box 409, the cylinder is started to drive the sealing plate 407 to move, so that the sealing plate 407 is separated from the discharge hole 406. When the sealing plate 407 moves, it will drive the scraper ring 408, and the scraper ring 408 can The crystallized salt in the groove 405 is scraped into the collecting box 409. When the crystallized salt in the groove 405 enters the collecting box 409, the cylinder is started to drive the sealing plate 407 to move in the opposite direction. When the sealing plate 407 blocks the discharge hole 406 and the scraper ring 408 fits the inner wall of the groove 405, the operation of the electric push rod 410 can be stopped.

[0043] The upper surface of the aggregate ring 403 is fixedly connected with a positioning ring 404, and the inner diameter of the positioning ring 404 is equal to the inner diameter of the aggregate ring 403. When the scraper 402 scrapes the crystallized salt on the upper surface of the aggregate ring 403, the positioning ring 404 can shield the crystallized salt on the aggregate ring 403, which can effectively prevent the crystallized salt from falling off the aggregate ring 403. The effect achieved by the entire salt collecting component 4 is that, by setting the salt collecting component 4, when the salt scraping component 3 scrapes the crystallized salt on the inner wall of the tank body 1, the crystallized salt can be automatically scraped into the groove 405 for collection, thereby improving the convenience of use of the MVR evaporator.

When the filter plate 501 is installed, the filter hole 502 can pre-treat and filter the black water entering the water inlet pipe 6. When the filter plate 501 needs to be replaced after wear and tear, first rotate the adjusting ring 505 to separate it from the slide rod 504, and then move the filter plate 501 to separate the slide hole 503 on the filter plate 501 from the slide rod 504, and the filter plate 501 can be disassembled.

[0045] A bearing 507 is installed on the side of the filter plate 501, and a plurality of scrapers 508 are fixedly connected to one side of the inner ring of the bearing 507.

A plug rod 510 is fixedly connected to one end of the connecting shaft 301, and the plug rod 510 is adapted to the size of the socket 509. When installing the filter plate 501, the plug rod 510 fixed on the connecting shaft 301 is first inserted into the socket 509 of the inner ring of the bearing 507. When the plug rod 510 is inserted into the socket 509, the rotation of the connecting shaft 301 will drive the bearing 507 to rotate, and the bearing 507 drives the scraper 508 to rotate, so that the scraper 508 can be rotated to scrape the dirt on one side of the filter plate 501 loosely, thereby preventing the dirt from clogging the filter hole 502 on the filter plate 501.

[0046] The cross-sections of the plug hole 509 and the plug rod 510 are both set to be regular hexagons. By setting the cross-sections of the plug rod 510 and the plug hole 509 to be regular hexagons, the stability of the plug rod 510 after being connected to the plug hole 509 can be improved. The entire filter assembly 5 has the following effects: by setting the filter assembly 5 and the filter plate 501, the black water entering the water inlet pipe 6 is pre-treated and filtered, thereby improving the practicality of the MVR evaporator, and after the filter plate 501 is worn out, it can be easily replaced by personnel.

[0047] The overall working principle is that when it is necessary to scrape off the crystallized salt attached to the inner wall of the tank body 1, the black water to be treated is first injected into the tank body 1 through the water inlet pipe 6. In the process of the black water passing through the water inlet pipe 6, it will drive a plurality of fan blades 304 to rotate, and the fan blades 304 will drive the connecting shaft 301 to rotate. During the rotation of the connecting shaft 301, the support rod 303 fixed on the inner wall of the water inlet pipe 6 will slide along the inner wall of the annular hole 302, and at the same time, the connecting shaft 301 will drive the active bevel gear 305 to rotate, and the active bevel gear 305 drives the driven bevel gear 307 to rotate, and the driven bevel gear 307 drives the rotating shaft 306 to rotate, and the rotating shaft 306 drives the connecting rod 310 to rotate, and the connecting rod 310 drives the scraper 311 to move along the inner wall of the tank body 1, so that the crystallized salt on the inner wall of the tank body 1 can be scraped off. , wherein, during the rotation of the rotating shaft 306, the fixing ring 308 and the fixing rod 309 can reinforce and support the rotating shaft 306, thereby improving the stability of the rotating shaft 306 during the rotation process. In addition, by setting a reinforcing rib 312 made of aluminum alloy at the connection between the scraper 311 and the connecting rod 310, the aluminum alloy is light in weight and high in strength, which can effectively improve the strength of the connection between the connecting rod 310 and the scraper 311. Finally, by setting the connecting shaft 301, the active bevel gear 305, the driven bevel gear 307, the rotating shaft 306, the connecting rod 310 and the scraper 311 to high-density polyethylene material, high-density polyethylene is a plastic material commonly used in water flow devices, has good corrosion resistance and strong toughness, and is light in weight, which can effectively improve the applicability of these parts.

[0048] In the process of scraping the crystallized salt on the inner wall of the tank body 1 by the scraper 311, the crystallized salt will fall on the upper surface of the aggregate ring 403. At this time, the rotation of the rotating shaft 306 will drive the connecting plate 401 to rotate, and the connecting plate 401 will drive the scraper 402 to move along the upper surface of the aggregate ring 403, so that the crystallized salt on the scraper 402 can be scraped into the groove 405. The personnel can move the sealing plate 407 to drive the scraper ring 408 to regularly take out the crystallized salt in the groove 405. When it is necessary to regularly collect the crystallized salt into the collection box 409, the cylinder is started to drive the sealing plate 407 to move, so that the sealing plate 407 is separated from the discharge hole 406. When the sealing plate 407 moves, it will drive the scraper ring 408, and the scraper ring 408 can scrape the crystallized salt inside the groove 405 into the collecting box 409. When the crystallized salt inside the groove 405 enters the collecting box 409, the cylinder is started to drive the sealing plate 407 to move in the opposite direction. When the sealing plate 407 blocks the discharge hole 406 and the scraper ring 408 fits with the inner wall of the groove 405, the operation of the electric push rod 410 can be stopped. In addition, in the process of the scraper 402 scraping the crystallized salt on the upper surface of the aggregate ring 403, the positioning ring 404 can block the crystallized salt on the aggregate ring 403, which can effectively prevent the crystallized salt from falling from the aggregate ring 403.

[0049] When it is necessary to install the filter plate 501 to pre-treat and filter the black water entering the water inlet pipe 6, first move the filter plate 501, insert the slide bar 504 into the slide hole 503 on the side of the filter plate 501, and then put the adjusting ring 505 on the arc surface of the slide bar 504, and rotate the adjusting ring 505 to abut against the filter plate 501 to complete the installation of the filter plate 501. When the filter plate 501 is installed, the filter hole 502 can pre-treat and filter the black water entering the water inlet pipe 6. When the filter plate 501 needs to be replaced after being worn out, first rotate the adjusting ring 505 to separate it from the slide bar 504, and then move the filter plate 501 so that the slide hole 503 on the filter plate 501 is aligned with the slide bar 50 4, the filter plate 501 can be disassembled. When installing the filter plate 501, the plug rod 510 fixed on the connecting shaft 301 is first inserted into the plug hole 509 of the inner ring of the bearing 507. After the plug rod 510 is inserted into the plug hole 509, the rotation of the connecting shaft 301 will drive the bearing 507 to rotate, and the bearing 507 drives the scraper 508 to rotate, so that the scraper 508 can be rotated to scrape the dirt on one side of the filter plate 501 loose, so as to prevent the dirt from clogging the filter hole 502 on the filter plate 501. In addition, by setting the cross-section of the plug rod 510 and the plug hole 509 to be a regular hexagon, the stability of the plug rod 510 after being connected to the plug hole 509 can be improved.
