Description

Technical Field

[0001] This application relates to the field of drying equipment technology, and more specifically, to a sodium pyroantimonate drying device. Background Technology

[0002] Sodium pyroantimonate is an important antimony salt compound, a white powder, commonly used as a glass clarifying agent and defoamer. It can also be used as a flame retardant synergist, an opaque filler, an emulsifier for enamel, and an acid-resistant paint for sheet metal and steel plates.

[0003] The prior art CN218443226U discloses an airflow dryer for preparing sodium pyroantimonate, including a conveying mechanism, a drying mechanism, and a dust removal mechanism. In use, a conveying motor drives the spiral blades to rotate and convey sodium pyroantimonate into the interior of the drying shell. A hot air pump injects hot air into the bottom of the drying shell. As the hot air rises, it comes into contact with the sodium pyroantimonate and removes the moisture from its surface. The rising airflow is extracted by the dust collector, and the sodium pyroantimonate falls onto the filter screen for continuous drying. After the sodium pyroantimonate is dried, an electric push rod pushes the connecting frame to move. The connecting frame drives the sealing plate and the arc plate to move synchronously. As the arc plate moves out, the sodium pyroantimonate falls into the interior of the collection shell.

[0004] When using the airflow dryer provided by the existing technology CN218443226U, the sodium pyroantimonate has a single drop point and is mainly concentrated on the side of the drying shell close to the conveyor shell, which affects the contact effect between hot air and sodium pyroantimonate. In addition, when sodium pyroantimonate accumulates on the filter screen, it will cause blockage, which will prevent hot air from continuously passing through the material layer and affect the drying effect of sodium pyroantimonate. Summary of the Invention

[0005] The purpose of this application is to provide a sodium pyroantimonate drying device, which can solve the technical problem that the low dispersion of sodium pyroantimonate affects the drying effect.

[0006] This application provides a sodium pyroantimonate drying device, including a drying box and a pretreatment mechanism. The lower end of the drying box is provided with a discharge pipe, and the inside of the drying box is provided with a cylinder that penetrates through the top of the cylinder. The cylinder has a hollow structure and openings are provided at both the upper and lower ends of the cylinder.

[0007] The pretreatment mechanism includes an air pump, a hot air duct, a conveyor box, a motor, and spiral blades. One end of the hot air duct is connected to the drying chamber, and the other end of the hot air duct is connected to the air pump. The conveyor box is located above the hot air duct, and a discharge pipe is provided at the lower end of the conveyor box, which is connected to the hot air duct. A feed hopper is provided at the upper end of the conveyor box. The motor is located outside the conveyor box, and the spiral blades are located inside the conveyor box. The motor drives the spiral blades to rotate.

[0008] Preferably, a dust removal filter bag is provided at the upper end of the cylinder.

[0013] Preferably, the lower end of the drying oven has a funnel-shaped structure.

[0014] The beneficial effects of this utility model are:

[0015] In the application of the drying device provided by this utility model, sodium pyroantimonate is fed into the interior of the conveying box through the feed hopper. The motor drives the spiral blades to convey the sodium pyroantimonate and improve its dispersion. The sodium pyroantimonate enters the interior of the hot air pipe through the discharge pipe. The air pump draws hot air into the interior of the hot air pipe, and the hot air blows the sodium pyroantimonate into the drying chamber. While the hot air blows the sodium pyroantimonate, it further improves the dispersion of the sodium pyroantimonate, so that the hot air and the sodium pyroantimonate can fully contact each other, thereby improving the drying effect of sodium pyroantimonate.

[0028] Example

[0029] like Figure 1-3 As shown in the figure, this application provides a sodium pyroantimonate drying device, including a drying chamber 1 and a pretreatment mechanism 2. The lower end of the drying chamber 1 is provided with a discharge pipe 3. The interior of the drying chamber 1 is provided with a cylinder 4 that penetrates through its top. The cylinder 4 has a hollow structure and openings 5 ​​at both the upper and lower ends. The pretreatment mechanism 2 includes an air pump 6, a hot air pipe 7, a conveying box 8, a motor 9, and a spiral blade 10. One end of the hot air pipe 7 is connected to the drying chamber 1, and the other end of the hot air pipe 7 is connected to the air pump 6. The conveying box 8 is located above the hot air pipe 7. The lower end of the conveying box 8 is provided with a discharge pipe 11, which is connected to the hot air pipe 7. The upper end of the conveying box 8 is provided with a feed hopper 12. The motor 9 is located outside the conveying box 8, and the spiral blade 10 is located inside the conveying box 8. The motor 9 drives the spiral blade 10 to rotate.

[0030] In use, sodium pyroantimonate to be dried is fed into the feed hopper 12. The sodium pyroantimonate is fed into the conveying box 8 from the feed hopper 12. The motor 9 drives the spiral blades 10 to convey the sodium pyroantimonate and improve its dispersion. The sodium pyroantimonate enters the hot air pipe 7 through the discharge pipe 11. At the same time, under the action of the air pump 6, hot air is drawn into the hot air pipe 7. The hot air blows the sodium pyroantimonate into the drying box 1. While the hot air blows the sodium pyroantimonate, it further improves the dispersion of the sodium pyroantimonate, so that the hot air and the sodium pyroantimonate can fully contact each other. The dried sodium pyroantimonate falls into the drying box 1, and the gas is discharged through the upper opening 5 of the cylinder 4.

[0031] In this embodiment, a dust filter bag 13 is provided at the upper end of the cylinder 4. The dust filter bag 13 is used to filter the exhaust gas to prevent the gas from carrying sodium pyroantimonate during discharge.

[0032] In this embodiment, a guide vane 14 is provided on the outer wall of the cylinder 4. The guide vane 14 is located inside the drying chamber 1. The guide vane 14 has a spiral structure. The arrangement of the guide vane 14 is beneficial to make the mixture of airflow and sodium pyroantimonate rotate around the cylinder 4, so as to prolong the passage time of the mixture of airflow and sodium pyroantimonate inside the drying chamber 1 and further improve the drying effect of sodium pyroantimonate.

[0033] In this embodiment, the drying oven 1 includes a box body 15 and a cover plate 16. A first flange 17 is provided on the box body 15, and a second flange 18 is provided on the cover plate 16. The cylinder 4 is disposed on the cover plate 16. The box body 15 and the cover plate 16 are connected by flanges. The flange connection can ensure the sealing effect between the cover plate 16 and the box body 15, and at the same time facilitates the periodic removal of the cover plate 16 to clean the cylinder 4 and the interior of the drying oven 1.

[0034] In this embodiment, the air inlet direction of the hot air duct 7 is parallel to the vertical tangential direction of the drying chamber 1. This structure facilitates the airflow to circulate in a spiral trajectory within the chamber 15, enhancing the contact efficiency between the hot air and sodium pyroantimonate and improving the drying effect of sodium pyroantimonate.

[0035] In this embodiment, the pretreatment mechanism 2 is provided in two sets. By increasing the number of feeding points, it is easier to form a rotating airflow inside the drying chamber 1.

[0036] In this embodiment, the lower end of the drying chamber 1 has a funnel-shaped structure, which facilitates the entry of the dried sodium pyroantimonate into the discharge pipe 3.

[0037] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
