Description

Technical Field

[0001] The utility model relates to the technical field of ferrous sulfate drying, in particular to a directional airflow stirring type ferrous sulfate microwave drying device. Background Art

[0002] Ferrous sulfate is an inorganic substance with the chemical formula of FeSO4. It is an odorless white powder. Its crystalline hydrate is a heptahydrate at room temperature, commonly known as "green vitriol". It is a light green crystal that weathers in dry air and oxidizes to brown basic ferric sulfate in humid air. It becomes a tetrahydrate at 56.6°C and a monohydrate at 65°C. Ferrous sulfate is soluble in water and almost insoluble in ethanol. Its aqueous solution oxidizes slowly in the air when it is cold and oxidizes faster when it is hot. Adding alkali or exposure to light can accelerate its oxidation. The relative density (d15) is 1.897. It is irritating. Ferrous sulfate can be used as a chromatographic analysis reagent, spot analysis to determine platinum, selenium, nitrite and nitrate. Ferrous sulfate can also be used as a reducing agent, to make ferrite, to purify water, as a polymerization catalyst, and for photoengraving.

[0025] The drying cylinder 2 is installed through the working plate 1, and the material is transported through the feed bin 3 at one end of the drying cylinder 2, and the gas is transported to the inside of the feed bin 3 through the blower 4. The gas stored in the feed bin 3 enters the drying cylinder 2 and moves obliquely toward the discharge elbow 19 to form multiple directional airflows. The directional airflow is used to stir the material. When the ferrous sulfate is dried, the discharge elbow 19 on one side of the drying cylinder 2 is disassembled and assembled, and the positioning ring 6 is installed on one side of the drying cylinder 2. The annular scraper 7 on one side of the positioning ring 6 can move horizontally to the inside of the drying cylinder 2. The movement of the annular scraper 7 can realize the cleaning of the inner wall of the drying cylinder 2 to ensure the cleaning of the inner wall of the drying cylinder 2. At the same time, the annular scraper 7 drives the outer cleaning ring 8 when it moves horizontally. The cleaning ring 8 contacts the inner wall of the drying cylinder 2, which can realize the discharge of waste and further scrub the inner wall of the drying cylinder 2, so that the device can not only stir the material through the directional airflow, but also clean it at any time after the drying of the device is completed, which is more convenient for users to use.

[0026] like Figure 4 and Figure 5 As shown, a support plate 11 is installed on one side of the annular scraper 7 through positioning bolts, a water storage bottle 9 is arranged on one side of the support plate 11, and an atomizing nozzle 10 is arranged on the other side of the support plate 11.

[0027] The support plate 11 is installed on one side of the annular scraper 7 by means of positioning bolts, and the water storage bottle 9 and the atomizing nozzle 10 are respectively threadedly installed on both sides of the support plate 11. When the inside of the drying cylinder 2 needs to be cleaned, the atomizing nozzle 10 and the water storage bottle 9 cooperate to spray water onto the inner wall of the drying cylinder 2, so that the inner wall of the drying cylinder 2 can be pre-treated.

[0028] like Figure 4 and Figure 5 As shown, a hollow cylinder is symmetrically arranged on one side of the annular scraper 7 , a hydraulic rod is arranged inside the hollow cylinder, and a hydraulic cylinder 20 connected to the positioning ring 6 is arranged at the output end of the hydraulic rod.

[0029] A hydraulic rod is installed through the hollow cylinder on one side of the annular scraper 7, and the hydraulic rod is adapted to the hydraulic cylinder 20. When the hydraulic cylinder 20 is working, the annular scraper 7 can move horizontally on the inner wall of the drying cylinder 2, thereby cleaning the inner wall of the drying cylinder 2.

When the trapezoidal plate 16 moves to the specified position, the ball 18 moves horizontally inside the working groove under the action of the return spring. At this time, the ball 18 is engaged with the limit slot 17, thereby realizing the positioning of the trapezoidal plate 16. Similarly, when the trapezoidal plate 16 moves, it can drive the cross bar 15 and the positioning ring 6 to rise and fall, making it convenient for users to disassemble and assemble the positioning ring 6.

[0032] like Figure 1 As shown, a steam filter plate 24 is disposed on the top of the drying cylinder 2, and an observation box 21 for observing the drying state of the material is disposed on one side of the drying cylinder 2.

[0033] The steam filter plate 24 on the top of the drying cylinder 2 can absorb the water vapor generated by the drying of ferrous sulfate, thereby ensuring the drying efficiency of the drying cylinder 2, thereby improving the drying quality of the material. At the same time, the observation box 21 on one side of the drying cylinder 2 can be used to check the drying condition of ferrous sulfate and the state of stirring and reversal, so as to further understand the drying condition of the material.

[0034] like Figure 1 and Figure 4 As shown, a base 22 is provided at the bottom of the working board 1 , and a storage box 23 is provided at the top of the base 22 and below the working board 1 .
