Description

Technical Field

[0001] The utility model relates to the technical field of mirabilite processing equipment, in particular to an impurity removal mechanism of a mirabilite centrifugal air drying device. Background Technique

[0002] The main component of mirabilite is anhydrous sodium sulfate, which is formed by boiling mirabilite with other drugs and then dehydrating and weathering the crystals. Due to different production areas and refining methods, the inclusions contained are also different.

[0003] Mirabilite is easy to absorb moisture and agglomerate. When the agglomerated mirabilite is centrifugally air-dried and decontaminated by a centrifugal air drying device, the air-drying and decontamination effect is not good. The agglomerated mirabilite powder directly falls under the influence of gravity, resulting in some mirabilite powder being discharged outside the device without sufficient air-drying and decontamination, thereby reducing the air-drying and decontamination efficiency. The agglomerated mirabilite powder will occupy the internal space of the device, making the device unable to work properly and reducing the work efficiency. Content of the Utility Model

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention.

[0021] Embodiment

[0022] Please refer to Figures 1-4 , the present invention provides a technical solution: an impurity removal mechanism of a Glauber's salt centrifugal air drying device, including a Glauber's salt air dryer 1, a Glauber's salt primary agglomeration and depolymerization mechanism 2, and a Glauber's salt centrifugal agglomeration, depolymerization and impurity removal mechanism 3. A drainage spiral blade is arranged inside the Glauber's salt air dryer 1. The Glauber's salt primary agglomeration and depolymerization mechanism 2 is located on one side of the top of the Glauber's salt air dryer 1, and the Glauber's salt centrifugal agglomeration, depolymerization and impurity removal mechanism 3 is located on one side of the bottom of the Glauber's salt air dryer 1. The Glauber's salt centrifugal agglomeration, depolymerization and impurity removal mechanism 3 includes a driving component, a centrifuge depolymerizer 31, a filter box 32 and a collection box 33. The centrifuge depolymerizer 31 is arranged in a circular structure. A feed inlet 315 is arranged at the top of the centrifuge depolymerizer 31. The feed inlet 315 is connected to the bottom discharge port of the Glauber's salt air dryer 1 through a second conveying pipe 314. A centrifugal rotating disk 311 is arranged inside the centrifuge depolymerizer 31. The outer circumferential wall of the centrifugal rotating disk 311 is not in low contact with the inner circumferential wall of the centrifuge depolymerizer 31, and an organic solution channel is reserved in the middle. A sealing door 312 is connected to the front side of the centrifuge depolymerizer 31 through a rotating shaft. A first conveying pipe 313 is connected through the middle of one side close to the outer wall of the sealing door 312. A fixed shaft is connected to one side of the centrifugal rotating disk 311 away from the sealing door 312. The fixed shaft passes through the shell of the centrifuge depolymerizer 31 through a bearing and extends to the outside thereof; the driving component includes a driving motor. The driving motor is located outside one side of the centrifuge depolymerizer 31 away from the outlet. The fixed shaft is connected to the output end of the driving motor through a coupling.

[0023] It should be noted that in this embodiment, the induced draft fan and the blower cooperate to form a drying and impurity-removing air flow channel. When the agglomerated mirabilite powder after being processed by the mirabilite dryer 1 enters the centrifuge depolymerizer 31 through the air flow channel for depolymerization, the driving motor drives the centrifugal rotating disk 311 to rotate at a high speed. Under the action of centrifugal force, the large particles of the agglomerated mirabilite powder will be thrown to the space between the inner wall of the outer peripheral centrifuge depolymerizer 31 and the centrifugal rotating disk 311. The finely divided mirabilite powder is sucked away at the center of the cavity of the centrifuge depolymerizer 31 and enters the filter box 32. The large particles collide and depolymerize with each other on the periphery until all the large particles are depolymerized. Since the depolymerization process is the mutual collision between mirabilite powder particles, no additional impurities will be generated, ensuring the impurity degree of the mirabilite powder itself.

[0024] Furthermore, the centrifuge depolymerizer 31 adopts the air flow depolymerization principle. By utilizing the different masses and kinetic energies of the mirabilite powder, the large particles are thrown out of the cavity periphery under the action of centrifugal force and continue to depolymerize. By efficiently utilizing the air flow, the production efficiency is improved.

[0025] Please refer to Figure 1 、 2 As shown in FIGS. 2 and 3, a filter mesh plate is provided inside the filter box 32, and a impurity collection box is provided below the filter mesh plate at the bottom of the filter box 32; a collection bag for collecting the impurity-removed mirabilite powder is provided inside the collection box 33, and the collection bag is connected to the first conveying pipe 313. One side of the top of the collection box 33 is connected to an induced draft fan through a pipe; the primary agglomerated mirabilite powder depolymerization mechanism 2 includes a primary depolymerizer 21, which is circularly structured. The bottom of the primary depolymerizer 21 is connected to the top feeding port of the mirabilite dryer 1, and the primary depolymerizer 21 is connected to the mirabilite powder feeding device. A blower is connected to the mirabilite powder feeding device, and the air of the blower is hot air. Inside the primary depolymerizer 21, a primary agglomerated depolymerization shaft rod 22 is connected through a driving device, and agglomerated depolymerization and crushing rods 23 are uniformly arranged on the outer circumferential wall of the primary agglomerated depolymerization shaft rod 22.

[0026] It should be noted that in this embodiment, the agglomerated mirabilite powder before entering the mirabilite dryer 1 is subjected to primary crushing and depolymerization by the primary agglomerated mirabilite powder depolymerization mechanism and then enters the mirabilite dryer 1 for drying. After primary depolymerization and drying, the mirabilite powder enters the mirabilite centrifugal agglomerated depolymerization and impurity-removing mechanism 3 for thorough depolymerization. After the impurities are intercepted by the filter mesh plate inside the filter box 32, the clean mirabilite powder is collected by the collection bag inside the collection box 33.

[0027] Further, the primary agglomeration and deaggregation mechanism 2 of mirabilite powder includes a primary deaggregator 21. Inside the primary deaggregator 21, a primary agglomeration and deaggregation shaft 22 is connected through a driving device. Agglomeration and deaggregation breaking rods 23 are evenly arranged on the outer circumferential wall of the primary agglomeration and deaggregation shaft 22. While driving the primary agglomeration and deaggregation shaft 22 to rotate through the driving device, the primary agglomeration and deaggregation shaft 22 on its outer circumferential wall further deaggregates the agglomerated mirabilite powder.

[0028] The working process of the present utility model:

[0029] When in use, the primary agglomeration and deaggregation mechanism 2 of mirabilite powder includes a primary deaggregator 21. Inside the primary deaggregator 21, a primary agglomeration and deaggregation shaft 22 is connected through a driving device. Agglomeration and deaggregation breaking rods 23 are evenly arranged on the outer circumferential wall of the primary agglomeration and deaggregation shaft 22. While driving the primary agglomeration and deaggregation shaft 22 to rotate through the driving device, the primary agglomeration and deaggregation shaft 22 on its outer circumferential wall further deaggregates the agglomerated mirabilite powder. The primarily deaggregated mirabilite powder enters the mirabilite powder air dryer 1 for drying. After the primarily deaggregated and dried mirabilite powder enters the mirabilite powder centrifugal agglomeration and deaggregation and impurity removal mechanism 3 for thorough deaggregation. The induced draft fan and the blower cooperate to form a drying and impurity removal air flow channel. When the agglomerated mirabilite powder after being processed by the mirabilite powder air dryer 1 enters the centrifuge deaggregator 31 inside through the air flow channel for deaggregation, the driving motor drives the centrifugal rotating disk 311 to rotate at a high speed. Under the action of centrifugal force, the large particles of the agglomerated mirabilite powder will be thrown to the inner wall of the outer peripheral centrifuge deaggregator 31 between the centrifugal rotating disk 311. The fine mirabilite powder is drawn away from the center of the cavity of the centrifuge deaggregator 31 and enters the filter box 32. After the impurities are intercepted by the filter mesh plate inside the filter box 32, the clean mirabilite powder is collected through the collection bag inside the collection box 33.

[0030] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
