In the drying process, the sodium tungstate crystal can be raised to a certain height with the rotation of the drying cylinder 3, and then falls under the action of gravity, so that the sodium tungstate crystal is mixed, and the drying efficiency is further improved.

[0067] Further, the device further comprises:

[0068] The feeding mechanism 8 is arranged at one end of the collecting cylinder 2 and communicates with the drying cylinder 3 through the collecting cylinder 2.

[0069] In the embodiment, the feeding mechanism 8 can be used to feed the sodium tungstate crystals into the drying cylinder 3. The feeding mechanism 8 can be a screw conveying mechanism, which can realize continuous feeding during drying.

[0070] Further, the collecting cylinder 2 comprises:

[0071] The left end cover 11 is arranged on the rack 1.

[0072] The collecting cylinder 12 is arranged at one end of the left end cover 11.

[0073] The right end cover 14 is arranged on the rack 1 and connected to the other end of the collecting cylinder 12. The sealing cover 15 is arranged on the right end cover 14.

[0074] In the embodiment, the first driving member 6 is connected to the drying cylinder 3 through the left end cover 11. One end of the opening 10 of the drying cylinder 3 is rotationally connected to the sealing cover 15 arranged on the right end cover 14 of the collecting cylinder 2. The first driving member 6 can drive the stable rotation of the drying cylinder 3. The drying space is formed between the drying cylinder 3 and the sealing cover 15, and the collecting space is formed between the left end cover 11, the collecting cylinder 12 and the right end cover 14.

[0075] Further, the collecting cylinder 12 has a semicircular structure. There are two collecting cylinders 12, which are oppositely arranged to form the collecting cavity 16, and the drying cylinder 3 is located in the collecting cavity 16.

[0076] In the embodiment, in order to facilitate the installation of the entire drying device, the cavity part of the collecting cylinder 2 is composed of two semicircular collecting cylinders 12. After the output end of the first driving member 6 is connected to the drying cylinder 3 through the left end cover 11, the two collecting cylinders 12 are buckled on the outside of the drying cylinder 3. The two collecting cylinders 12 wrap the drying cylinder 3 in the collecting cavity 16.

[0077] Further, the side wall of the drying cylinder 3 has a plurality of discharge holes 17, the inner wall of the collecting cylinder 12 has a plurality of guide grooves 13, the plurality of guide grooves 13 are parallel and spaced apart on the inner wall of the collecting cylinder 12, and the discharge mechanism 4 comprises:

[0078] An annular guide plate 18 is rotationally arranged in the guide groove 13, and the annular guide plate 18 has a plurality of mounting holes 19, the plurality of mounting holes 19 are circumferentially and spaced apart on the annular guide plate 18;

[0079] A connecting sleeve 20 is arranged on the mounting hole 19, and the connecting sleeve 20 penetrates the mounting hole 19;

[0080] A limiting plate 21 is arranged at one end of the connecting sleeve 20, and the limiting plate 21 is located in the guide groove 13;

[0081] A plugging column 22 is located in the discharge hole 17, and the plugging column 22 has a cylindrical segment 23 and a conical segment 24, the cylindrical segment 23 is slidably arranged at the other end of the connecting sleeve 20, the conical segment 24 is connected to the other end of the cylindrical segment 23, and the conical segment 24 is located in the drying cylinder 3;

[0082] A first elastic member 25 is arranged at both ends of the connecting sleeve 20 and the plugging column 22 respectively.

[0083] In the embodiment, the annular guide plate 18 is arranged in the guide groove 13, so that the sodium tungstate powder can be prevented from entering the guide groove 13, and the collection efficiency is improved. During the drying process, the collecting cylinder 2 and the drying cylinder 3 are not connected, the cylindrical segment 23 of the plugging column 22 is located in the discharge hole 17, and the sodium tungstate crystals in the drying cylinder 3 cannot enter the collecting cylinder 2. After the drying is completed, the rotating speed of the drying cylinder 3 is increased by the first driving member 6, the discharge mechanism 4 rotates with the drying cylinder 3, as the rotating speed increases, the centrifugal force acting on the plugging column 22 increases, at this time, the plugging column 22 slides along the connecting sleeve 20 to the side away from the drying cylinder 3, the first elastic member 25 is compressed, and the conical segment 24 enters the discharge hole 17. There is a gap between the conical segment 24 and the discharge hole 17, and the sodium tungstate powder can enter the collecting cylinder 2 through the gap. The annular guide plate 18 always seals the guide groove 13 during rotation, so that the sodium tungstate powder cannot enter the guide groove 13, and the sodium tungstate powder can be collected very conveniently. During the process of increasing the rotating speed of the drying cylinder 3, the rotating speed of the drying cylinder 3 can be periodically adjusted, at this time, the plugging column 22 reciprocally slides in the connecting sleeve 20, which can knock the collecting cylinder 2, so that the sodium tungstate powder adhered to the inner wall of the collecting cylinder 2 falls to the bottom of the collecting cylinder 2 quickly, and the sodium tungstate powder can be finally collected conveniently.

[0084] Furthermore, the inner wall of the drying cylinder 3 has receiving grooves 26, which are triangular in structure. Multiple receiving grooves 26 are circumferentially spaced on the inner wall of the drying cylinder 3. It also includes...

[0085] A toggle plate 27 is rotatably disposed within a receiving groove 26. A torsion spring connects the toggle plate 27 and the drying cylinder 3. One tip of the receiving groove 26, away from the hinge point of the toggle plate 27, is located on the inner wall of the drying cylinder 3.

[0086] In this embodiment, the actuating plate 27 is always in a tilted state under the action of the torsion spring, such as Figure 3 As shown. During the rotation of the drying cylinder 3, the sodium tungstate powder can be lifted to a certain height. The dispersion plate 9 has a groove in the middle, as shown. Figure 4 As shown, when the actuating plate 27 passes below the dispersing plate 9, both ends of the dispersing plate 9 abut against the actuating plate 27, causing the actuating plate 27 to rotate towards the receiving groove 26. Simultaneously, due to the presence of the groove, sodium tungstate crystals accumulate on the actuating plate 27. After passing the dispersing plate 9, the actuating plate 27 resets under the action of the torsion spring, ejecting some of the accumulated sodium tungstate crystals. These ejected sodium tungstate crystals can mix with other sodium tungstate crystals in the drying cylinder 3, improving drying efficiency. The remaining sodium tungstate crystals on the actuating plate 27 rise to a certain height and then fall to mix. The receiving groove 26 has a triangular structure. When each receiving groove 26 rotates above the drying cylinder 3, the sodium tungstate crystals within it can fall off automatically, facilitating equipment cleaning.

[0087] Furthermore, it also includes:

[0088] A guide trough 28 is provided on the collecting cylinder 2. The guide trough 28 is located at the bottom of the side wall of the collecting cylinder 2 and is connected to the collecting cylinder 2.

[0089] The pusher plate 29 is slidably disposed within the guide groove 28;

[0090] The first telescopic member 30 is disposed on the guide groove 28. The first telescopic member 30 is located on the outside of the guide groove 28, and the pusher plate 29 is connected to the extended end of the first telescopic member 30.

[0091] In this embodiment, the sodium tungstate powder in the collecting cylinder 2 eventually falls into the guide trough 28 under the action of gravity. After collection is completed, the first telescopic member 30 is extended, and the sodium tungstate powder in the guide trough 28 is pushed out by the pusher plate 29 and collected into the container.

[0092] An energy-saving rapid drying method for sodium tungstate, using an energy-saving rapid drying device for sodium tungstate, includes the following steps:

[0095] S3: collecting: during the drying process, the rotation speed of the drying cylinder 3 can be controlled by the first driving member 6, after the rotation speed of the drying cylinder 3 is increased, the discharge mechanism 4 is subjected to a larger centrifugal force, the blocking column 22 slides along the discharge hole 17 to the side away from the drying cylinder 3, the drying cylinder 3 is communicated with the collecting cylinder 2, and the dried sodium tungstate powder enters the collecting cylinder 2 through the discharge hole 17;

[0097] In this embodiment, when the sodium tungstate crystals are dried, the sodium tungstate crystals are first fed into the drying cylinder 3 through the feeding mechanism 8, then the first driving member 6 and the heater 7 are started, the first driving member 6 can drive the drying cylinder 3 to rotate, and the heater 7 can raise the temperature of the heating rod 5. During the rotation of the drying cylinder 3, the dispersion plate 9 can uniformly disperse the sodium tungstate crystals accumulated together on the inner wall of the drying cylinder 3. After the sodium tungstate crystals pass through the gap between the dispersion plate 9 and the drying cylinder 3, they are raised to a certain height by the rotation of the drying cylinder 3 and then fall. When the toggle plate 27 passes under the dispersion plate 9, the two ends of the dispersion plate 9 abut against the toggle plate 27, the toggle plate 27 rotates to the side of the containing groove 26, and the toggle plate 27 is reset under the action of the torsional spring after passing through the dispersion plate 9, which can eject part of the sodium tungstate crystals accumulated on the toggle plate 27. The ejected sodium tungstate crystals can mix with other sodium tungstate crystals in the drying cylinder 3 to improve the drying efficiency. The remaining sodium tungstate crystals on the toggle plate 27 are raised to a certain height and then fall to mix. After the sodium tungstate crystals are dried, they become sodium tungstate powder. At this time, the rotation speed of the drying cylinder 3 is increased by the first driving member 6. As the rotation speed increases, the centrifugal force acting on the blocking column 22 increases. At this time, the blocking column 22 slides along the connecting sleeve 20 to the side away from the drying cylinder 3, the first elastic member 25 is compressed, and the conical section 24 enters the discharge hole 17. The conical section 24 and the discharge hole 17 have a gap, and the sodium tungstate powder can enter the collecting cylinder 2 through the gap.
