[0002] A drum flaker is an auxiliary device for chemical product flaking in chemical production. Drum flaking is a cooling crystallization process. The molten liquid in the pan contacts the cooled drum, forming a material film on the surface of the drum. Through the heat exchange between the material film and the drum, the material film is cooled and crystallized, and the crystallized material is scraped off by a scraper to become a flaky product.
[0003] The drum flaker is mainly equipped with a scraper on the arc side of the drum, but the side of the drum is often ignored. However, in actual production, materials often condense on the side of the drum. If not cleaned in time, it will affect the operation of the drum. Excessive accumulation may even jam the drum, causing equipment damage and affecting production. In the prior art, the side scraper is usually fixedly installed, and the crystallized material often causes the scraper to adhere to the drum, generating great resistance to the operation of the drum and even jamming the drum, which has an adverse impact on production.

[0023] The side scraper assembly 4 includes two fixed rods 41, a cross bar 42, a side scraper 43, a driving motor 44, and an eccentric wheel 45. One end of each of the two fixed rods 41 is connected to the frame 1. The cross bar 42 is slidably inserted through the other ends of the two fixed rods 41. A limit groove 46 is provided at one end of the cross bar 42. The side scraper 43 is installed on the cross bar 42. Buffer springs 47 and return springs 48 are respectively provided between the side scraper 43 and the two fixed rods 41. The buffer spring 47 is provided on the side close to the limit groove 46, and the return spring 48 is provided on the side far from the limit groove 46. The driving motor 44 is installed on the bracket 1. The output end of the driving motor 44 is connected to the eccentric wheel 45, and the eccentric wheel 45 is clamped in the limit groove 46. The cross bar 42 is a hollow tube, and a steam inlet pipe 491 and a steam outlet pipe 492 are respectively connected to both ends of the cross bar 42. The driving motor 44 is connected to a gearbox and a controller, and the controller controls the output speed of the driving motor 44 through the gearbox.
[0024] A liquid collection tank 82 is provided on one side of the frame 1. An overflow pipe 81 is connected to the material tray 5, and the overflow pipe 81 is connected to the liquid collection tank 82. The liquid collection tank 82 is connected to a reflux pump 83, and the reflux pump 83 is connected to the material tray 5 through a pipeline. Heating devices are provided on the liquid collection tank 82, the overflow pipe 81, and the pipeline between the reflux pump 83 and the material tray 5 to prevent the liquid in the liquid collection tank 82 and the pipeline from crystallizing.
[0025] The usage process of the present utility model:
[0026] The drum 2 of the flaker rotates, and the drum 2 remains in a low-temperature cooling state. The liquid material enters the tray 5 and contacts the drum 2. The steam heating pipe 53 arranged at the bottom of the tray 5 continuously heats the tray 5 to prevent the material in the tray 5 from crystallizing. As the drum 2 rotates, the liquid material condenses on the surface of the drum 2. The main scraper 3 scrapes off the crystalline material on the arc surface of the drum 2. The crystalline material falls into the discharge port 6 and is sent out through the spiral discharge chute 7;
[0027] When the material condenses and forms flakes on the surface of the drum 2, some material will also condense on the side of the drum 2. Start the drive motor 44 of the side scraper assembly 4 and adjust the output speed of the drive motor 44 according to the rotation speed of the drum 2 and the actual production situation. The eccentric wheel 45 rotates in the limit groove 46 and pushes the cross bar 42 to move. Under the action of the return spring 48, the cross bar 42 reciprocates, driving the side scraper 43 to reciprocate. The side scraper 43 continuously scrapes the crystalline material on the side of the drum 2. The continuous movement can effectively prevent the material from adhering to the surface of the side scraper 43, enabling the material to slide off the surface of the side scraper 43 smoothly. Steam inlet pipes 491 and steam outlet pipes 492 are connected to both ends of the cross bar 42. The cross bar 42 and the side scraper 43 are heated by steam, which can dissolve and flow down a small amount of material adhering to the surface of the side scraper 43; The material scraped off by the side scraper 43 falls into the tray 5. Due to the continuous heating of the steam heating pipe 53, the crystalline material falling into the tray 5 quickly melts without affecting the continuous operation of the flaker;
[0028] The tray 5 is connected with an overflow pipe 81. The material flows into the liquid collecting tank 82 through the overflow pipe 81 to prevent the material in the tray 5 from overflowing. After the material enters the liquid collecting tank 82, it can be sent back to the tray 5 by the reflux pump 83 for continued flaking.
[0029] For the various preferred and optional technical means disclosed in the present invention, except as specifically stated and except when one preferred or preferably selectable technical means is a further limitation of another technical means, they can be arbitrarily combined to form several different technical solutions. Therefore, equivalent changes made according to the claims still fall within the scope covered by the present invention.
