[0026] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0027] like Figure 1 and Figure 2 As shown, a salt collecting leg for a circulating evaporator in one embodiment of the present invention comprises a circulating evaporator 1 and a salt collecting leg 2. The salt collecting leg 2 is mounted on and connected to the circulating evaporator 1. A discharge pipe 22 is connected to the salt collecting leg 2, through which the ammonium sulfate wastewater in the salt collecting leg 2 is discharged. During operation of the circulating evaporator 1, the ammonium sulfate wastewater therein concentrates to a certain concentration, increasing its density and causing it to be deposited in the salt collecting leg 2. Simultaneously, the ammonium sulfate wastewater in the salt collecting leg 2 produces crystal particles, which are deposited at the bottom of the salt collecting leg 2.

[0028] In order to prevent the deposited crystal particles from adhering to the inner wall of the salt collecting leg 2, a circulation pipe 21 is connected to the salt collecting leg 2, and a slurry pump 211 is installed on the circulation pipe 21. A baffle 23 is welded to the inner wall of the salt collecting leg 2. The baffle 23 is located between the circulation pipe 21 and the discharge pipe 22. The baffle 23 is provided with a filtrate hole 2301. The discharge pipe 22 is installed with an external discharge valve 221 that can prevent the discharge pipe 22 from being opened or closed.

[0029] Specifically, the crystal particles deposited in the salt collecting leg 2 will fall on the baffle 23 and be blocked by the baffle 23 from entering the discharge pipe 22. When the slurry pump 211 on the circulation pipe 21 is started, the ammonium sulfate wastewater in the salt collecting leg 2 will enter the circulation pipe 21 with the crystal particles. After the circulation impact of the slurry pump 211, the ammonium sulfate wastewater in the salt collecting leg 2 will be broken, so that the ammonium sulfate wastewater in the salt collecting leg 2 is in a suspended state. When the ammonium sulfate wastewater in the salt collecting leg 2 reaches a certain concentration, the external discharge valve 221 on the discharge pipe 22 is opened, and the ammonium sulfate wastewater in the salt collecting leg 2 flows into the discharge pipe 22 from the filtrate hole 2301 on the baffle 23 and can be discharged through the discharge pipe 22. In this way, no crystal particles will be deposited in the salt collecting leg 2, the inner wall of the salt collecting leg 2 can be protected, and the discharge pipe 22 will not be blocked.

[0030] To monitor the state of the ammonium sulfate wastewater within the salt collecting leg 2, an observation assembly is embedded in the salt collecting leg 2 to monitor the crystallization of the ammonium sulfate wastewater within the leg 2. The observation assembly includes an observation window 24 that extends through the leg 2 and is sealed to the leg 2. A transparent plastic plate 4 is integrally formed on the observation window 24.

[0031] Specifically, the crystallization of the ammonium sulfate wastewater in the salt collecting leg 2 can be checked through the plastic plate 4, thereby determining the time to start the slurry pump 211. This can save energy and also check the crystallization of the ammonium sulfate wastewater after being impacted, and determine the time to open the discharge valve 221.

[0032] It is worth noting that since the ammonium sulfate wastewater is in a turbid state after being impacted by the slurry pump 211, the turbid ammonium sulfate wastewater will adhere to the plastic plate 4. Long-term use will cause the plastic plate 4 to lose its transparency, making it impossible to see the situation inside the salt collecting leg 2 clearly.

[0033] like Figures 3 to 6 As shown, a pair of slide rails 3 are bonded to the inner wall of the salt collecting leg 2. A second magnet block 32 is slidably connected to the pair of slide rails 3. A second slider 321 is integrally formed on the second magnet block 32. The pair of slide rails 3 are provided with a second chute 31 that matches the second slider 321. The second magnet block 32 is slidably connected to the second chute 31 via the second slider 321. The second magnet block 32 is wrapped with a protective layer 322, and a plastic scraper 323 is integrally formed on the protective layer 322.

[0034] Specifically, by sliding the second magnet block 32 upward, the plastic scraper 323 on the second magnet block 32 can clean the plastic plate 4, scraping off the dirt adhering to the plastic plate 4 and restoring the plastic plate 4 to a transparent state.

[0035] Since ammonium sulfate wastewater is corrosive, to prevent corrosion, the slide rail 3 is a plastic rail and the protective layer 322 is a plastic protective layer. Plastic molecules are composed of saturated chemical valence bonds and lack free electrons or mobile ions that can form electrochemical reactions with the medium. Therefore, electrochemical corrosion does not occur, and the plastic can be prevented from being corroded by ammonium sulfate wastewater.

[0036] To enable the second magnet block 32 to slide upward within the second chute 31, a first magnet block 242 that matches the second magnet block 32 is slidably connected to the observation window 24. A first slider 2421 is integrally formed on the first magnet block 242, and a first chute 241 that matches the first slider 2421 is defined on the observation window 24. The first magnet block 242 is slidably connected to the first chute 241 via the first slider 2421.

[0037] Specifically, when the first magnet block 242 slides upward in the first slide groove 241, the second magnet block 32 slides upward in the second slide groove 31 at the same time under the action of magnetic attraction, so that the plastic scraper 323 on the second magnet block 32 can clean the plastic plate 4.

[0038] It is worth noting that since the plastic scraper 323 is inside the salt collecting leg 2, the plastic scraper 323 will become dirty after long-term use. In order to clean the dirt on the plastic scraper 323, Figure 1 and Figure 5Before the slurry pump 211 is activated, the ammonium sulfate wastewater in the salt collecting leg 2 is still turbid. At this time, the first magnet block 242 is slid back and forth, driving the second magnet block 32 to move up and down in the ammonium sulfate wastewater. The impact force between the plastic scraper 323 and the ammonium sulfate wastewater can wash away the dirt on the plastic scraper 323.

[0039] Preferably, the first magnet block 242 and the second magnet block 32 are both neodymium iron boron magnets. Neodymium iron boron magnets have excellent magnetic properties and can provide very strong magnetic attraction in a relatively small volume.

[0040] like Figure 4 and Figure 5 As shown, a handle 2422 is integrally formed on the first magnet block 242 . When sliding the first magnet block 242 , holding the handle 2422 can better exert force, and sliding the first magnet block 242 can also be more convenient.

[0041] During use, the ammonium sulfate wastewater in the salt collecting leg 2 will produce crystal particles. These crystal particles fall on the baffle 23 and are blocked by the baffle 23 and will not enter the discharge pipe 22. Start the slurry pump 211 on the circulation pipe 21, and the ammonium sulfate wastewater in the salt collecting leg 2 will enter the circulation pipe 21 with the crystal particles, and will break after the circulation impact of the slurry pump 211. When the ammonium sulfate wastewater in the salt collecting leg 2 reaches a certain concentration, open the external discharge valve 221 on the discharge pipe 22, and the ammonium sulfate wastewater in the salt collecting leg 2 will flow into the discharge pipe 22 from the filtrate hole 2301 on the baffle 23, and can be discharged through the discharge pipe 22. In this way, crystal particles will not be deposited in the salt collecting leg 2, the inner wall of the salt collecting leg 2 can be protected, and the discharge pipe 22 will not be blocked.

[0042] Compared with the prior art, the salt collecting leg for a circulating evaporator of the utility model can make the ammonium sulfate wastewater in the salt collecting leg flow, and can prevent scaling on the inner wall of the salt collecting leg to a certain extent, thereby increasing the service life of the salt collecting leg, and at the same time can also prevent blockage of the discharge pipe.

[0043] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
