Description

Technical Field

[0001] This utility model relates to the technical field of high-salt waste liquid treatment, and in particular to a chemical waste liquid purification and salt separation device. Background Technology

[0002] A large amount of high-salt waste liquid is generated during chemical production. Currently, the main method for separating salt from high-salt waste liquid is distillation. Distillation has become the most widely used method for salt separation in industrial production due to its advantages of simple structure, convenient operation, strong adaptability to high-salt waste liquid, and good effluent quality. Its core principle is to boil and evaporate the waste liquid by heating, and then condense and recover the steam to crystallize and precipitate the salt to achieve the separation of salt and water.

[0003] Existing chemical waste liquid purification and salt separation devices mostly consist of heating components and separation cylinders. The working process is as follows: the chemical waste liquid to be treated is poured into the separation cylinder, the heating components are started to continuously heat the waste liquid in the separation cylinder. As the water evaporates, the salt concentration in the waste liquid gradually increases until it reaches a supersaturated state and crystallizes out. After the heating process is completed, the steam generated by evaporation is treated and then distilled and discharged, while the salt is retained in the separation cylinder. The salt can be directly poured out by the staff to complete the separation operation between the salt and the waste liquid.

[0004] However, in the above separation method, the salt solidifies and adsorbs onto the inner wall of the separation cylinder when heated inside. The accumulation of a large amount of solidified salt reduces the heating effect of the heating components, thus requiring a longer heating time, which affects the separation efficiency of salt in chemical waste liquid.

[0016] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0017] The chemical waste liquid purification and salt separation device of this utility model embodiment is described below with reference to the accompanying drawings.

[0018] like Figures 1-4 As shown, the chemical waste liquid purification and salt separation device of this utility model includes a working support 1, a driving component 2, a separation component 3, a heating component 4, and a discharge component 5.

[0019] The working support 1 is provided with a support plate 10, and the drive assembly 2 is provided on the working support 1.

[0020] In this embodiment of the application, the driving component 2 is used to drive and control the rotation of the separation component 3.

[0021] The separation component 3 rotates on the working support 1, and the drive component 2 is connected to the separation component 3 in a transmission manner.

[0022] In this embodiment, the separation component 3 is used to separate waste liquid and salt.

[0023] The heating component 4 is mounted on the separation component 3.

[0024] It should be noted that the heating component 4 described in this embodiment includes a heating wire (not shown in the figure) and a temperature controller (not shown in the figure). The heating wire is disposed on the separation cylinder 31 in the separation component 3, and the temperature controller is electrically connected to the heating wire. Its controller (not shown in the figure) is electrically connected to the temperature controller.

[0025] The discharge assembly 5 includes an auger mechanism 50 and a scraper cylinder 51.

[0026] The auger mechanism 50 is fixedly mounted on the support plate 10 and is sealed and inserted into the separation cylinder 31 in the separation assembly 3. The scraper cylinder 51 is mounted on the auger mechanism 50 and is connected to the scraper cylinder 51. The scraper cylinder 51 is provided with a scraper plate 510, and the scraper plate 510 abuts against the inner wall of the separation cylinder 31.

[0027] It should be noted that the scraper cylinder 51 described in this embodiment is arranged vertically through the material, so that the salt scraped off by the scraper plate 510 falls into the auger mechanism 50 through the scraper cylinder 51 and is discharged to the outside of the separator cylinder 31 through the auger mechanism 50.

[0028] It should be noted that the scraper cylinder 51 described in this embodiment is funnel-shaped, and the top of the scraper cylinder 51 is close to the inner wall of the separation cylinder 31, so that after the separation cylinder 31 is heated, heat loss from the scraper cylinder 51 is reduced.

[0029] Specifically, in actual operation, relevant personnel pour waste liquid into the separation cylinder 31, but do not fill the separation cylinder 31 completely. After filling, the device is started, and the controller controls the heating component 4 to heat the separation cylinder 31, thereby heating the waste liquid in the separation cylinder 31. After continuous heating, the salt in the waste liquid gradually precipitates out and is adsorbed on the inner wall of the separation cylinder 31. The drive component 2 runs to drive the separation component 3 to rotate, and drives the separation cylinder 31 to rotate. When the separation cylinder 31 rotates, the scraper 510 continuously abuts against the separation cylinder 31, scraping the solid salt on the wall of the separation cylinder 31 into the scraper cylinder 51. The controller then controls the auger mechanism 50 to rotate, and the auger mechanism 50 transports the solid salt to the outside of the separation component 3 for collection. This process is repeated to complete the separation of salt in the waste liquid.

[0030] In one embodiment of this utility model, such as Figures 1-3 As shown, the auger mechanism 50 includes a discharge motor 500, a discharge cylinder 501, and an auger shaft 502.

[0031] The discharge motor 500 is mounted on the support plate 10, the discharge cylinder 501 is fixedly mounted on the support plate 10, and the discharge cylinder 501 is sealed and inserted into the separation cylinder 31. The auger shaft 502 is rotatably mounted inside the discharge cylinder 501, and the output shaft of the discharge motor 500 is connected to the auger shaft 502.

[0032] It should be noted that one end of the discharge cylinder 501 described in this embodiment is open, so as not to affect the discharge of solid salt. In addition, the discharge cylinder 501 is rotatably inserted into the middle of the distribution cylinder, so as not to affect the rotation of the distribution cylinder.

[0033] In one embodiment of this utility model, such as Figures 1-3 As shown, a water leakage hole is provided at the bottom of the discharge cylinder 501.

[0034] It should be noted that when the discharge cylinder 501 described in this embodiment has a water leakage hole at the bottom, the amount of liquid added to the separation cylinder 31 does not submerge the water leakage hole, thereby ensuring the water leakage effect of the water leakage hole.

[0035] In one embodiment of this utility model, such as Figures 1-3 As shown, the separation component 3 also includes an insulation cylinder 30.

[0036] The separating cylinder 31 is fixedly installed inside the heat preservation cylinder 30. The heat preservation cylinder 30 is rotatably connected to the working support 1, and the driving component 2 is drivenly connected to the heat preservation cylinder 30. The heat preservation cylinder 30 is provided with a drain pipe 300, the separating cylinder 31 is provided with multiple steam valves 310, and the separating cylinder 31 is provided with a liquid inlet pipe 311, which extends to the outside of the heat preservation cylinder 30.

[0037] Understandably, the heat preservation cylinder 30 can keep the heat on the separation cylinder 31 warm, thereby reducing heat loss.

[0038] In one embodiment of this utility model, such as Figures 1-3 As shown, the drive assembly 2 includes a drive motor 20 and a drive gear 21.

[0039] The drive motor 20 is mounted on the working support 1, and the drive gear 21 is mounted on the output shaft of the drive motor 20. The drive gear 21 is meshed with the gear ring mounted on the insulation cylinder 30.

[0040] Specifically, the drive motor 20 rotates, which drives the drive gear 21 to rotate. The drive gear 21 rotates and meshes with the gear ring to rotate, which in turn drives the insulation cylinder 30 and the separation cylinder 31 to rotate.

[0041] Specifically, in actual operation, relevant personnel pour waste liquid into the separation cylinder 31, without filling it completely. After filling, the device is started, and the controller controls the heating component 4 to heat the separation cylinder 31, thereby heating the waste liquid inside. After continuous heating, the salt in the waste liquid gradually precipitates out and adsorbs onto the inner wall of the separation cylinder 31. The drive motor 20 rotates, driving the drive gear 21 to rotate, which in turn drives the insulation cylinder 30 and the separation cylinder 31 to rotate. When the separation cylinder 31 rotates, the scraper 510 continuously abuts against the separation cylinder 31, scraping the solid salt on the wall of the separation cylinder 31 into the scraper cylinder 51. The controller then controls the discharge motor 500 to rotate, which drives the auger shaft 502 to rotate. The auger shaft 502 transports the solid salt to the outside of the insulation cylinder for collection. In addition, the evaporated liquid is discharged from the steam valve 310 and collected in the insulation cylinder 30, and then discharged through the drain pipe 300. The relevant staff repeated the above operations to complete the separation of salt from the waste liquid.

[0042] In summary, the chemical waste liquid purification and salt separation device of this utility model adopts a scraping and discharge method to continuously clean up the solidified salt, thereby improving the separation efficiency of waste liquid salt.
