[0002] The temperature of high-temperature industrial waste salt is relatively high, which can reach 700-800°C. High-temperature industrial waste salt is in liquid state. In order to recycle industrial waste salt, it is necessary to cool the high-temperature industrial waste salt so that the high-temperature industrial waste salt can be crystallized.

[0003] The existing cooling mainly uses a cooling plate, which is made of metal. The high-temperature industrial waste salt is introduced into the cooling plate to cool the high-temperature industrial waste salt. In order to increase the cooling speed, cooling water can be set under the cooling plate. When the high-temperature industrial waste salt is cooled, the industrial waste salt is manually knocked out of the cooling plate.

[0004] The existing method of cooling high-temperature industrial waste salt uses a cooling plate for cooling, which has a small heat exchange area during cooling, resulting in a long cooling time and low cooling efficiency. In addition, since the high-temperature industrial waste salt is directly injected into the cooling plate, there are certain safety hazards. When removing the industrial waste salt from the cooling plate, it needs to be manually knocked and then the cooling plate is turned over, which is time-consuming and laborious. Summary of the invention

The secondary cooling drum is used to cool the high-temperature industrial waste salt falling from the feed gap; a first scraper is arranged in the casing and abuts against the side of the first cooling drum away from the second cooling drum; a second scraper is arranged in the casing and abuts against the side of the second cooling drum away from the first cooling drum; a third scraper is arranged in the casing and abuts against one side of the secondary cooling drum; a driving device is arranged on the casing and connected to the first cooling drum, the second cooling drum and the secondary cooling drum, and is used to drive the first cooling drum, the second cooling drum and the secondary cooling drum to rotate; and a screw conveyor is arranged at the discharge port.

[0007] Preferably, the driving device includes: a first driving component, which is arranged on one side of the casing and connected to the first cooling drum and the second cooling drum respectively, and is used to make the first cooling drum and the second cooling drum rotate in opposite directions and rotate synchronously; and a second driving component, which is arranged on the other side of the casing and connected to the secondary cooling drum.

[0017] Embodiment 1

[0018] like Figures 1 to 3As shown, a high-temperature industrial waste salt flake machine includes a casing 7, a first cooling drum 1, a second cooling drum 2, a secondary cooling drum 3, a first scraper 41, a second scraper 43, a third scraper 45, a driving device and a screw conveyor 8. The casing 7 is mounted on a frame 73, and the frame 73 improves the strength of the casing 7. A feed port 71 is provided at the top of the casing 7, and the feed port 71 is used to feed high-temperature industrial waste salt. The bottom of the casing 7 is funnel-shaped, and a discharge port 72 is provided at the bottom, and the discharge port 72 is used to discharge the industrial waste salt that has been cooled and crystallized. The screw conveyor 8 is installed at the bottom of the casing 7 and is connected to the frame 73. The inlet of the screw conveyor 8 is also connected to the discharge port 72 of the casing 7, and is used to transport the cooled industrial waste salt. The first cooling drum 1, the second cooling drum 2 and the secondary cooling drum 3 are coaxially provided with a first rotating shaft 11, a second rotating shaft 21 and a secondary rotating shaft 31 respectively. The first rotating shaft 11, the second rotating shaft 21 and the secondary rotating shaft 31 are all hollow rotating shafts, and the parts located inside the cooling drums are all provided with through holes, and the through holes make the first rotating shaft 11, the second rotating shaft 21 and the secondary rotating shaft 31 communicate with the interior of the first cooling drum 1, the second cooling drum 2 and the secondary cooling drum 3 respectively; both ends of the first rotating shaft 11, the second rotating shaft 21 and the secondary rotating shaft 31 are rotatably mounted on the frame 73 through bearing seats, and are all located inside the casing 7. The first rotating shaft 11 is provided with a first water inlet and a first water outlet at both ends respectively; the second rotating shaft 21 is provided with a second water inlet and a second water outlet at both ends respectively, the second cooling drum 2 and the first cooling drum 1 are symmetrically arranged, a feed gap 6 is provided between the second cooling drum 2 and the first cooling drum 1, and the feed gap 6 is arranged opposite to the feed port 71; the secondary cooling drum 3 is located below the feed gap 6, and the third water inlet and the third water outlet are provided at both ends of the secondary rotating shaft 31 respectively, and the secondary cooling drum 3 is used to cool the high-temperature industrial waste salt dropped from the feed gap 6. The first scraper 41 is fixed in the casing 7 through the first bracket 42, and the first scraper 41 is against the side of the first cooling drum 1 away from the second cooling drum 2, that is, the first scraper 41 is located on the side of the first cooling drum 1 away from the feed gap 6; the second scraper 43 is fixed in the casing 7 through the second bracket 44, and is against the side of the second cooling drum 2 away from the first cooling drum 1, that is, the second scraper 43 is located on the side of the second cooling drum 2 away from the feed gap 6; the third scraper 45 is fixed in the casing 7 through the third bracket 46, and is against one side of the secondary cooling drum 3; the first scraper 41, the second scraper 43 and the third scraper 45 are respectively used to scrape off the industrial waste salt condensed on the surfaces of the first cooling drum 1, the second cooling drum 2 and the secondary cooling drum 3, and the scraped industrial waste salt enters the interior of the screw conveyor 8 through the discharge port 72, and then the screw conveyor 8 sends the industrial waste salt to the next process. The driving device is installed on the side of the casing 7, and is connected to the first cooling drum 1, the second cooling drum 2 and the secondary cooling drum 3, and is used to drive the first cooling drum 1, the second cooling drum 2 and the secondary cooling drum 3 to rotate.

[0019] The first water inlet, the second water inlet and the third water inlet are all connected to the cooling water system for introducing cooling water, the first water outlet, the second water outlet and the third water outlet are all connected to the cooling water system for discharging cooling water, and the cooling water system is used for circulating cooling of the first cooling drum 1, the second cooling drum 2 and the secondary cooling drum 3. The cooling water cools the high-temperature industrial waste salt through the first cooling drum 1, the second cooling drum 2 and the secondary cooling drum 3.

[0020] Liquid high-temperature industrial waste salt enters the interior of the casing 7 through the feed port 71, and then falls into the feed gap 6 between the first cooling drum 1 and the second cooling drum 2. Since the temperatures of the first cooling drum 1 and the second cooling drum 2 are relatively low, the high-temperature industrial waste salt will be cooled and crystallized on the surfaces of the first cooling drum 1 and the second cooling drum 2. The first cooling drum 1 and the second cooling drum 2 rotate while cooling the high-temperature industrial waste salt, so that the temperature of the industrial waste salt on the surface of the first cooling drum 1 and the second cooling drum 2 gradually decreases. Since the scraper is on the side away from the feed gap 6, the cooling time of the industrial waste salt on the surface of the first cooling drum 1 and the second cooling drum 2 is extended, which can effectively ensure the cooling of the industrial waste liquid and reduce the temperature of the industrial waste salt to about 400°C. Since the temperature of high-temperature industrial waste salt is as high as 700-800°C and it is in liquid, part of the high-temperature industrial waste liquid will flow out directly from the feed gap 6. This part of the industrial waste salt is also cooled, but the temperature is still as high as 500-600°C. If this part of the high-temperature industrial waste salt directly enters the screw conveyor 8 without cooling, the temperature of the screw conveyor 8 will be very high. When the screw conveyor 8 is in a high temperature state, on the one hand, the temperature of the bearings and the motor will be high, affecting the service life of the bearings and the motor. On the other hand, the high-temperature industrial waste salt is easy to adhere to the spiral blades of the screw conveyor 8, and cause the spiral blades to soften and deform. The deformed spiral blades cause the screw conveyor 8 to fail to feed normally, and blockage is prone to occur, which in turn causes the screw conveyor 8 to be scrapped. Therefore, it is necessary to cool down the high-temperature industrial waste salt that flows directly out of the feed gap 6, so as to protect the screw conveyor 8. The secondary cooling drum 3 cools down this part of the high-temperature industrial waste salt to 400-500°C, which greatly reduces the temperature of the high-temperature industrial waste salt entering the screw conveyor 8, increases the service life of the screw conveyor 8, and locks the cooling time of the high-temperature industrial waste salt, thereby improving the efficiency of flaking.

[0021] Although narrowing the feed gap 6 will reduce the amount of high-temperature industrial waste salt that directly leaks to the bottom, it will also reduce the amount of high-temperature industrial waste salt cooled by the first cooling drum 1 and the second cooling drum 2, reducing efficiency. At the same time, it will cause the feed speed to be greater than the discharge speed, which will easily lead to blockage. The high-temperature industrial waste salt will accumulate between the first cooling drum 1 and the second cooling drum 2, that is, above the feed gap 6, affecting normal operation. Therefore, it is necessary to ensure that the feed gap 6 can allow part of the high-temperature industrial waste liquid to flow directly to the bottom, balance the feed speed and the discharge speed, and ensure reliable, stable and continuous cooling of the high-temperature industrial waste salt.

[0022] A spray structure can be provided inside the first cooling drum 1, the second cooling drum 2, and the secondary cooling drum 3 to achieve uniform cooling. The first cooling drum 1, the second cooling drum 2, and the secondary cooling drum 3 are all existing mature products, and the high-temperature industrial waste salt on the surface is cooled by internal cooling water, which will not be described in detail here.

[0023] The driving device includes a first driving assembly and a second driving assembly. The first driving assembly is arranged on one side of the housing 7 and is connected to the first cooling drum 1 and the second cooling drum 2 respectively, so as to make the first cooling drum 1 and the second cooling drum 2 rotate in opposite directions and rotate synchronously. The second driving assembly is arranged on the other side of the housing 7 and is connected to the secondary cooling drum 3. Specifically, the first driving assembly includes a first motor 51, a first driving gear 52, a first transmission gear 53, a first driven gear 54 and a second driven gear 55. The first motor 51 is installed on one side of the housing 7 and is connected to the first driving gear 52. The first transmission gear 53 is rotatably installed on the housing 7 or the frame 73 through a bearing seat and meshes with the first driving gear 52. The first transmission gear 53 and the second driven gear 55 are both meshed with the first driving gear 52. The first driven gear 54 and the second driven gear 55 are respectively connected to the first rotating shaft 11 and the second rotating shaft 21 of the first cooling drum 1 and the second cooling drum 2. The first driving gear 52, the first driven gear 54 and the second driven gear 55 realize the reduction transmission and improve the torque output by the first motor 51. The first driven gear 54, the first transmission gear 53 and the second driven gear 55 make the rotation directions of the first cooling drum 1 and the second cooling drum 2 opposite, and the opposite rotation directions can make the high-temperature industrial waste salt stably cooled and crystallized on the surfaces of the first cooling drum 1 and the second cooling drum 2. The second driving assembly includes a second motor 56, a second driving gear and a secondary driven gear 58. The second motor 56 is installed on the other side of the housing 7 and is connected to the second driving gear. The second driving gear is meshed with the secondary driven gear 58, and the secondary driven gear 58 is fixed on the secondary rotating shaft 31 of the secondary cooling drum 3.

[0024] The first cooling drum 1, the second cooling drum 2 and the secondary cooling drum 3 can automatically cool and flak the high-temperature industrial waste salt, and the flaked industrial waste salt can be automatically scraped off by the first scraper 41, the second scraper 43 and the third scraper 45, and concentrated on the screw conveyor 8 for automatic delivery, thereby realizing the automatic flaking of the high-temperature industrial waste salt, reducing labor costs, and improving efficiency and safety.

[0025] The cooling is carried out through the upper and lower layers of cooling drums, thereby ensuring that the industrial waste salt is cooled to 400-500°C, achieving a reliable cooling effect and improving the cooling efficiency.

[0026] Embodiment 2

[0027] like Figures 1 to 3 As shown, a method for flake forming of high-temperature industrial waste salt includes the following steps: starting a flake forming machine, the first cooling drum 1 and the second cooling drum 2 rotate in opposite directions and both rotate along the flow direction of the high-temperature industrial waste salt, the first cooling drum 1 rotates clockwise and the second cooling drum 2 rotates counterclockwise; the high-temperature industrial waste liquid enters between the first cooling drum 1 and the second cooling drum 2 through the feed port 71; part of the high-temperature industrial waste salt crystallizes on the first cooling drum 1 and the second cooling drum 2, and part of the high-temperature industrial waste salt drips onto the secondary cooling drum 3 through the feed gap 6, and the secondary cooling drum 3 cools and crystallizes the high-temperature industrial waste salt; the first scraper 41, the second scraper 43 and the third scraper 45 scrape the industrial waste salt on the surfaces of the first cooling drum 1, the second cooling drum 2 and the secondary cooling drum 3; the screw conveyor 8 transports the industrial waste salt.

[0028] There is no requirement for the rotation direction of the secondary cooling drum 3, which can rotate clockwise or counterclockwise. When the third scraper 45 rotates clockwise, it is located on the left side of the secondary cooling drum 3 to ensure the cooling time of the industrial waste salt on the secondary cooling drum, so that the temperature of the industrial waste salt drops to 400-500° C. Similarly, when the third scraper 45 rotates counterclockwise, it is located on the right side of the secondary cooling drum 3.

[0029] The technical principle of the present invention is described above in conjunction with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations herein, those skilled in the art can associate other specific implementations of the present invention without paying creative labor, and these methods will fall within the protection scope of the claims of the present invention.
