Description

Technical Field

[0001] The utility model relates to a flake machine, in particular to a high-temperature industrial waste salt flake device. Background Art

[0002] The temperature of high-temperature industrial waste salt is relatively high, reaching 700-800°C. High-temperature industrial waste salt is in liquid form. In order to recycle industrial waste salt, it is necessary to cool the high-temperature industrial waste salt and allow the high-temperature industrial waste salt to crystallize.

[0003] Industrial waste salt is primarily crystallized using a flaker, also known as a condensation crystallizer, scraper, or drum slicer. This machine passes high-temperature liquid raw material through a stainless steel internally cooled roller, which rotates within the trough of the device and is then scraped by an adjustable slicing blade at the front. The resulting liquid is then cooled by the rollers and converted into solid flakes. For example, CN103285770A discloses a dual-drum flaker and flake method that uses two rollers to cool high-temperature industrial waste salt. However, since the temperature of high-temperature industrial waste salt reaches 700-800℃, when this structure is used for cooling, some of the high-temperature industrial waste salt will fall directly after the initial cooling, and will not be able to stick to the drum to continue cooling. The temperature of this part of high-temperature industrial waste salt reaches 500-600℃, and the temperature of the industrial waste salt is still relatively high. When the high-temperature industrial waste salt is transported in the screw conveyor, on the one hand, the temperature of the screw conveyor is very high, affecting the service life of the bearings and motors. On the other hand, the high-temperature industrial waste salt is easy to stick to the spiral blades of the screw conveyor, and cause the spiral blades to soften and deform. The deformed spiral blades cause the screw conveyor to fail to feed normally, and are prone to blockage, which in turn causes the screw conveyor to be scrapped.

[0004] High-temperature industrial waste salt greatly shortens the service life of the screw conveyor, and because the temperature is still high after passing through the flaker, secondary cooling is required, resulting in a long overall flak time. Utility Model Content

[0015] The present invention will now be further described with reference to the accompanying drawings.

[0016] like Figures 1 to 3As shown, a high-temperature industrial waste salt flake device includes 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 and a drive device. The casing 7 is mounted on a frame 73, which increases the strength of the casing 7. A feed port 71 is provided at the top of the casing 7 for feeding high-temperature industrial waste salt. The bottom of the casing 7 is funnel-shaped and is provided with a discharge port 72 for discharging cooled and crystallized industrial waste salt. A screw conveyor 8 is mounted at the bottom of the casing 7 and connected to the frame 73. The inlet of the screw conveyor 8 is also connected to the discharge port 72 of the casing 7 for conveying 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, which 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 is symmetrically arranged with the first cooling drum 1, and 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 second rotating shaft 31 is provided with a third water inlet and a third water outlet at both ends respectively, and the secondary cooling drum 3 is used to cool the high-temperature industrial waste salt falling 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.

[0017] 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. 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.

[0018] 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 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 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.

[0019] Although narrowing the feed gap 6 will reduce the amount of high-temperature industrial waste salt that leaks directly 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 cause 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.

[0020] The first cooling drum 1, second cooling drum 2, and secondary cooling drum 3 can be equipped with a spray structure to achieve uniform cooling. The first cooling drum 1, second cooling drum 2, and secondary cooling drum 3 are all existing mature products. They use internal cooling water to cool the high-temperature industrial waste salt on their surfaces. They will not be described in detail here.

[0021] The driving device includes a first driving assembly and a second driving assembly. The first driving assembly is provided on one side of the housing 7 and is connected to the first cooling drum 1 and the second cooling drum 2, respectively, for making the first cooling drum 1 and the second cooling drum 2 rotate in opposite directions and rotate synchronously. The second driving assembly is provided 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 mounted on the housing 7 or the frame 73 through a bearing seat and is meshed 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 a reduction gear transmission and increase 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 first cooling drum 1 and the second cooling drum 2 rotate in opposite directions. The opposite rotation directions enable the high-temperature industrial waste salt to be stably cooled and crystallized on the surfaces of the first cooling drum 1 and the second cooling drum 2. The second drive assembly includes a second motor 56, a second driving gear, and a secondary driven gear 58. The second motor 56 is mounted on the other side of the housing 7 and is connected to the second driving gear. The second driving gear meshes with the secondary driven gear 58, and the secondary driven gear 58 is fixed to the secondary rotating shaft 31 of the secondary cooling drum 3.

[0022] The first cooling drum 1, the second cooling drum 2 and the secondary cooling drum 3 can automatically cool and flake the high-temperature industrial waste salt, and automatically scrape off the flakes of industrial waste salt through the first scraper 41, the second scraper 43 and the third scraper 45, and collect them on the screw conveyor 8 for automatic delivery, thereby realizing the automatic flakes of high-temperature industrial waste salt, reducing labor costs, and improving efficiency and safety.

[0023] 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 cooling efficiency.
