Description

Technical Field

[0001] This utility model relates to the technical field of ferrous sulfate processing, and in particular to a drying device for ferrous sulfate. Background Technology

[0002] Ferrous sulfate is an important chemical raw material widely used in water treatment, pharmaceuticals, agriculture and other fields.

[0003] Currently, the drying process of ferrous sulfate is crucial in industrial production. Ferrous sulfate typically exists as ferrous sulfate heptahydrate, which contains a large amount of water of crystallization and is hygroscopic and unstable. Traditional drying methods often employ vibrating fluidized beds, boiling beds, airflow drying, and drum drying. However, during the initial drying process, the precipitation of surface water and water of crystallization in ferrous sulfate heptahydrate can easily lead to material sticking to the walls and agglomeration, causing equipment blockage and wall slagging. This not only results in uneven drying of ferrous sulfate but also produces incompletely dried granular material, ultimately affecting the production quality of ferrous sulfate. Utility Model Content

The discharge pipe is connected to the bottom of the oil-guiding assembly, and both the exhaust pipe and the discharge pipe pass through the heat-insulating tank. The cover plate is mounted on the top of the heat-insulating tank and the oil-guiding assembly.

[0007] The present invention relates to a drying device for ferrous sulfate, which effectively prevents oxidation and wall adhesion of ferrous sulfate during the drying process, thereby eliminating equipment blockage and ensuring uniform drying and production quality.

[0018] 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.

[0019] The drying apparatus for ferrous sulfate according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0020] The drying device for ferrous sulfate provided in this embodiment can be applied to the production of ferrous sulfate. During the drying process, it effectively prevents oxidation and wall adhesion of ferrous sulfate, thereby eliminating equipment blockage and ensuring the uniformity of ferrous sulfate drying and production quality.

[0021] like Figures 1-3 As shown, the drying device for ferrous sulfate according to this embodiment of the present invention may include an installation mechanism 1, a vacuum assembly 2, a stirring assembly 3, an air outlet pipe 4, a discharge pipe 5, and a cover plate 6.

[0022] It should be noted that a condensing assembly (existing technology, so it will not be described in detail) can be installed on the mounting mechanism 1 to collect the water vapor generated during the drying process.

[0023] The installation mechanism 1 may include a bracket 11, an insulation tank 12, an oil guiding assembly 13, and a drying tank 14.

[0024] Understandably, the support bracket 11 provides support for the insulation tank 12, the oil guiding assembly 13, and the drying tank 14.

[0025] The heat preservation tank 12 is mounted on the bracket 11, the oil guiding assembly 13 is located inside the heat preservation tank 12, and the drying tank 14 is installed inside the oil guiding assembly 13.

[0026] It should be noted that the support 11 supports the heat preservation tank 12, and the heat preservation tank 12 keeps the temperature carried by the oil guiding assembly 13 warm. Finally, the drying process of ferrous sulfate is completed inside the drying tank 14.

[0027] Vacuum assembly 2 is located on one side of the heat preservation tank 12.

[0028] It should be noted that, under the action of the vacuum component 2, the air inside the drying tank 14 is extracted, thereby ensuring that the inside of the drying tank 14 is under negative pressure.

[0029] The stirring assembly 3 is mounted on the bracket 11, and the output end of the stirring assembly 3 is inserted into the interior of the drying tank 14.

[0030] It should be noted that the stirring component 3 is used to complete the stirring process during the drying of ferrous sulfate.

[0031] The vent pipe 4 is connected to the top of the oil guiding assembly 13, and the discharge pipe 5 is connected to the bottom of the oil guiding assembly 13. Both the vent pipe 4 and the discharge pipe 5 pass through the heat preservation tank 12.

[0032] It should be noted that, under the action of the gas outlet pipe 4, the acidic gas is collected during the drying process of ferrous sulfate.

[0033] As one possible scenario, the outlet pipe 4 can be connected to the spray tower to complete the spray filtration of acidic gases.

[0034] The cover plate 6 is installed on top of the insulated tank 12 and the oil guiding assembly 13.

[0035] It should be noted that the top of the heat preservation tank 12 and the oil guiding assembly 13 described in the above embodiments are provided with a feed inlet.

[0036] Understandably, the cover plate 6 seals off the top space of the insulation tank 12 and the oil guiding assembly 13, thus preventing the inability to create a vacuum.

[0037] Specifically, in the actual operation, when drying ferrous sulfate, the relevant personnel pour the ferrous sulfate to be dried into the drying tank 14. Then, under the action of the oil guiding component 13, the heat transfer oil enters the oil guiding component 13, and then the internal temperature of the oil guiding component 13 is heated. During the heating process, the heat preservation tank 12 prevents the heat transfer oil in the oil guiding component 13 from losing temperature. Then, under the action of the stirring component 3, the ferrous sulfate is stirred during the drying process. After drying, the vacuum component 2 reverses the air intake to discharge the acidic gas in the drying tank 14 through the gas outlet pipe 4, and then discharges the dried ferrous sulfate through the discharge pipe 5.

[0038] In one embodiment of this utility model, such as Figures 1-3 As shown, the oil guiding assembly 13 may include an oil inlet pipe 131 and an oil guiding pipe 132.

[0039] It should be noted that the oil guide pipe 132 described in the above embodiment is wrapped around the outside of the drying tank 14.

[0040] The oil inlet pipe 131 is installed on one side of the heat preservation tank 12, and the oil guide pipe 132 is connected to the oil inlet pipe 131. The oil guide pipe 132 is located inside the heat preservation tank 12.

[0041] Understandably, the heat transfer oil is discharged through the oil inlet pipe 131, and then the internal temperature of the drying tank 14 is heated through the oil guide pipe 132.

[0042] In one embodiment of this utility model, such as Figures 1-3 As shown, vacuum assembly 2 may include vacuum pump 21, exhaust pipe 22 and suction pipe 23.

[0043] It should be noted that the vacuum pump 21 described in the above embodiment is mounted on one side of the heat preservation tank 12 via a support plate.

[0044] The vacuum pump 21 is installed on one side of the heat preservation tank 12, the exhaust pipe 22 is connected to the outlet end of the vacuum pump 21, the inlet end of the vacuum pump 21 is connected to the suction pipe 23, and the suction pipe 23 passes through the heat preservation tank 12 and is connected to the oil guide assembly 13.

[0045] Understandably, the vacuum pump 21 extracts air from the inside of the drying tank 14 through the suction pipe 23 and discharges the air through the exhaust pipe 22, thereby creating a negative pressure inside the drying tank 14 to lower the boiling point of the precipitated water.

[0046] In one embodiment of this utility model, such as Figures 1-3 As shown, the stirring assembly 3 may include a stirring motor 31, a bolt pusher 32, and a scraper 33.

[0047] It should be noted that the bolt pusher 32 described in the above embodiment is equipped with a throwing blade on its outer side.

[0048] The stirring motor 31 is mounted on the bracket 11, the bolt pusher 32 is rotatably mounted inside the oil guiding assembly 13, the output end of the stirring motor 31 passes through the heat preservation tank 12 and the oil guiding assembly 13 and is connected to the bolt pusher 32, and the scraper 33 is mounted on the top of the bolt pusher 32 and contacts the inner wall of the oil guiding assembly 13.

[0049] Specifically, driven by the stirring motor 31, the bolt pusher 32 stirs the ferrous sulfate, and then the scraper 33 scrapes off the ferrous sulfate adhering to the inner wall of the drying tank 14 to prevent the ferrous sulfate from adhering to the inner wall of the drying tank 14.

[0050] In summary, the drying device for ferrous sulfate according to this utility model effectively prevents oxidation and wall adhesion of ferrous sulfate during the drying process, thereby eliminating equipment blockage and ensuring the uniformity of ferrous sulfate drying and production quality.
