Description

Technical Field

[0001] The invention relates to the technical field of solid-liquid separation, and in particular to a drying device and an ammonium molybdate dryer. Background Art

[0002] Ammonium molybdate is an inorganic salt with a white powder or colorless to light yellow-green appearance. Its melting point is about 170℃ (decomposition), density is 2.498g / cm³, and it is easily soluble in water, acid and alkali, but insoluble in alcohol. Ammonium molybdate is the basic raw material for the production of high-purity molybdenum products, molybdenum catalysts, molybdenum pigments, etc. It is widely used in smelting molybdenum iron, preparing molybdenum trioxide and metallic molybdenum powder, and as a raw material for tungsten-molybdenum alloys and molybdenum wires. In addition, it is also used in geological exploration of phosphate mines, chemical catalysts, agricultural molybdenum fertilizers and medicine, and is a component of many enzymes. Its preparation methods mainly include ion exchange method, ammonia leaching method and water washing method. Among them, ion exchange method has become the mainstream preparation method due to its advantages such as good finished product quality, simple operation process and suitability for large-scale production.

[0003] After the preparation of ammonium molybdate, solid-liquid separation is required to obtain pure ammonium molybdate crystals. At present, solid-liquid separation of ammonium molybdate is usually carried out by combining filtration and drying;

[0004] In the prior art, for example, the patent document with the announcement number CN108245958B discloses a filtering and drying rotary device suitable for ammonium molybdate, and also discloses that after the product enters the filter tank, solid-liquid separation is performed, the solid is on the filter grid, and the filtrate is vacuum filtered through the filter grid and is pumped from the filtrate outlet into the vacuum tank to achieve solid-liquid separation; during drying, hot air enters the filter tank from the shaft end of the filter tank and directly contacts the solid on the filter grid, and the moisture attached to the solid is guided out from the filtrate outlet into the collection tank by the hot air, and the solid is dried by the hot air; after drying, the filter tank is rotated by the gear driven by the reducer;

[0005] However, in actual application, since ammonium molybdate has a certain thickness on the filter grid, the surface of the crystal will dry quickly during drying, but the internal moisture cannot be discharged in time, resulting in a humidity difference between the inside and the outside, thereby causing agglomeration. Therefore, the prior art uses a filter cartridge to replace the filter grid for solid-liquid separation, and drives the filter cartridge to rotate during the filtration process to ensure the uniformity of drying. However, this method is very cumbersome when loading and unloading, and the filter cartridge needs to be disassembled and assembled multiple times for loading or unloading, which reduces the drying efficiency. Summary of the invention

[0006] The object of the present invention is to provide a drying device and an ammonium molybdate dryer to solve the following technical problems:

[0007] Since ammonium molybdate has a certain thickness on the filter grid, the surface of the crystal will dry quickly during drying, but the internal moisture cannot be discharged in time, resulting in a humidity difference between the inside and the outside, thereby causing agglomeration.

[0024] An ammonium molybdate dryer comprises any one of the above-mentioned drying devices, and the ammonium molybdate dryer is used for solid-liquid separation of ammonium molybdate materials.

[0025] Beneficial effects of the present invention:

[0026] (1) In the initial state of the present invention, the second drying section is located at the bottom of the drying box and is at a certain distance from the opening, so that the ammonium molybdate to be separated into solid and liquid can be input into the second drying section, and the first solid-liquid separation is performed through the filtrate hole opened in the second drying section. Then, the second drying section is driven by the lifting module to move into the drying box and merge with the first drying section to form a complete cylindrical structure. At the same time, the first air supply section and the second air supply section are merged to form a complete air supply cylinder. When the first drying section and the second drying section are merged, the positioning rod and the positioning hole are synchronously plugged and matched, so that when the rotating part drives the first drying section to rotate, the second drying section can be synchronously driven to rotate. Therefore, under the action of centrifugal force, the liquid on the ammonium molybdate can be thrown out from the filtrate hole to achieve the effect of secondary solid-liquid separation; the present invention arranges two groups of semicircular drying parts and air supply parts, so that in the process of loading and unloading, the two can be directly separated and then merged, while the complete circular filter cylinder in the prior art needs to be provided with a loading port and a unloading port, so before centrifugal drying, the loading port and the unloading port need to be sealed, and at the same time, after the drying is completed, due to the narrow material port, the ammonium molybdate particles are easily attached to the cylinder wall and cannot be removed, the present invention directly separates the two, the material is completely exposed, and it is convenient to unload and the attached material can be effectively removed;

[0027] (2) After the second solid-liquid separation of ammonium molybdate is performed in the present invention, the air delivery cylinder delivers the heated air to the air supply cylinder formed by the first air supply section and the second air supply section, and finally the hot air can be delivered to the first drying section and the second drying section through the air holes. During this process, the rotating part continuously drives the first drying section and the second drying section to rotate, so that the ammonium molybdate material inside them can be continuously turned over, which can effectively avoid the phenomenon that the crystal surface is dried quickly and the internal moisture cannot be discharged in time during drying, forming a humidity difference between the inside and the outside, thereby causing agglomeration. Accordingly, when the ammonium molybdate material is dried, the second drying section is driven to descend to the initial position by the lifting module, and the dried ammonium molybdate crystals can be discharged by turning over the second drying section, which makes the discharge more convenient and effectively improves the solid-liquid separation and drying efficiency of ammonium molybdate.

[0028] (3) In the present invention, when the second drying section is located at the initial position, based on the setting of the push rod, the push rod can pass through the drainage groove to lift the sealing plate to separate from the drainage groove, and the first spring is stretched to generate elastic force. At this time, the liquid after solid-liquid separation can pass through the drainage groove and fall into the storage box. When the sealing box rises with the second drying section, the push rod loses the lifting effect on the sealing plate. Each first spring can drive the sealing plate to embed into the drainage groove for sealing, thereby preventing hot air from being discharged from the drainage groove during the drying process. At this time, the liquid after solid-liquid separation can temporarily stay in the sealing box. As the sealing box is reset after the drying is completed, the liquid can be discharged accordingly.

[0029] (4) In the present invention, after the drying of ammonium molybdate is completed, the second drying section is reset to the initial position. As the lifting module continues to drive the second air supply section to move downward, the two sets of baffles also move away from each other, and then the collecting box is driven to rotate to the bottom of the second drying section by the adjusting section. As it continues to move downward, the second half gear engages with the first rack to drive the second drying section to flip toward the storage box. After flipping 180 degrees, the movement stops. At this time, the ammonium molybdate crystals in the second drying section can fall completely into the collecting box, achieving the effect of automatic material dropping.

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Example 1

[0042] See also Figure 1-Figure 3 As shown, the present invention is a drying device, comprising a drying box 1 and a drying module; in one implementation of this embodiment, an opening is provided at the bottom of the drying box 1;

[0043] The drying module includes a first drying section 5 arranged in the drying box 1 and a second drying section 503 arranged at the bottom of the drying box 1. The first drying section 5 and the second drying section 503 are both semi-cylindrical structures, and a plurality of groups of filtrate holes 505 are evenly opened on the first drying section 5 and the second drying section 503; specifically, the first drying section 5 and the second drying section 503 form a complete cylindrical structure when combined;

[0044] The first air supply part 502 is fixedly arranged at the axial end of the first drying section 5, and both ends of the first air supply part 502 extend and are rotatably connected to the side wall of the drying box 1. The drying box 1 is provided with a rotating part, which is used to drive the first air supply part 502 to rotate. The second air supply part 504 is fixedly arranged at the axial end of the second drying section 503. Both the first air supply part 502 and the second air supply part 504 are semi-cylindrical structures, and a plurality of groups of air holes 506 for communicating with the inside of the drying section are evenly opened on the first air supply part 502 and the second air supply part 504; specifically, the first air supply part 502 and the second air supply part 504 form a complete cylindrical structure when combined;

[0045] The second drying section 503 is also provided with a lifting module arranged on one side of the second drying section 503, and the lifting module is used to drive the second drying section 503 to rise and fall, so as to be combined with or separated from the first drying section 5; specifically, in the initial state, the second drying section 503 is located at the bottom of the drying box 1 and is at a certain distance from the opening, so that the ammonium molybdate to be separated from the solid and liquid can be uniformly input into the second drying section 503, and the preliminary solid-liquid separation is carried out through the filtrate hole 505 provided on the second drying section 503, and then the second drying section 503 is driven by the lifting module to move into the drying box 1 and merge with the first drying section 5 to form a complete cylindrical structure, at the same time, the first air supply section 502 and the second air supply section 504 are combined to form a complete air supply cylinder, and then the first air supply section 502 is driven to rotate by the rotating section, and the first air supply section 502 can synchronously drive the first drying section 5 and the second drying section 503 to rotate during the rotation of the first air supply section 502, so that the liquid on the ammonium molybdate can be thrown out from the filtrate hole 505 under the action of centrifugal force, so as to achieve the effect of secondary solid-liquid separation;

[0046] Among them, one end of the first air supply part 502 is rotatably connected to the air cylinder 501, and the other end of the air cylinder 501 is connected to the heat source; it can be explained that after the combined air supply part performs secondary solid-liquid separation on ammonium molybdate, the air cylinder 501 conveys the heated air to the air supply cylinder formed by the first air supply part 502 and the second air supply part 504, and finally the hot air can be conveyed to the first drying part 5 and the second drying part 503 through the air hole 506. During this process, the rotating part continuously drives the first drying part 5 and the second drying part 503 to rotate, so that the ammonium molybdate material inside them can be continuously turned over, which can effectively avoid the rapid drying of the crystal surface and the inability to discharge the internal moisture in time during drying, forming a humidity difference between the inside and the outside, thereby causing agglomeration. Correspondingly, when the ammonium molybdate material is dried, the second drying part 503 is driven to descend to the initial position by the lifting module, and the dried ammonium molybdate crystals can be discharged by flipping the second drying part 503, which is more convenient to discharge and effectively improves the solid-liquid separation and drying efficiency of ammonium molybdate.

[0047] In addition, the heat source in this embodiment can be a hot air blower or a heat pump, which is not limited.

[0048] Example 2

[0049] Based on Example 1, please refer to Figure 1-Figure 3 , the rotating part includes a first half gear 105 fixedly arranged at the end of the first air supply part 502, and also includes a second half gear 511 fixedly arranged at the end of the second air supply part 504. The driving motor 102 is fixedly arranged on the drying box 1, and a first gear 103 meshing with the first half gear 105 is rotatably arranged on the side wall of the drying box 1. The output end of the driving motor 102 is connected to the first gear 103 through a pulley structure. It can be explained that when the first air supply part 502 is driven to rotate, the driving motor 102 is started, and the driving motor 102 drives the first gear 103 to rotate through the pulley structure. The first gear 103 drives the first air supply part 502 to rotate by meshing with the first half gear 105. When the first drying part 5 and the second drying part 503 are merged, the first half gear 105 and the second half gear 511 are merged to form a complete gear, so that the first gear 103 can be synchronously meshed with the first half gear 105 and the second half gear 511 alternately to realize transmission.

[0050] Also, see Figure 3 Two groups of first supports 507 are symmetrically fixedly arranged on both sides of the first drying section 5, and positioning holes 508 are provided on the first supports 507, wherein two groups of second supports 509 are symmetrically fixedly arranged on both sides of the second drying section 503, and positioning rods 510 for plugging and cooperating with the positioning holes 508 are fixedly arranged on the second supports 509; it can be explained that when the first drying section 5 and the second drying section 503 are combined, the positioning rod 510 is synchronously plugged and cooperated with the positioning hole 508, so that when the rotating part drives the first drying section 5 to rotate, the second drying section 503 can be synchronously driven to rotate.

[0051] As a further solution of this embodiment, please refer to Figure 1 A storage box 2 for storing filtrate is also arranged at the bottom of the second drying section 503; specifically, after the ammonium molybdate material is separated into solid and liquid and dried, the filtrate falls into the storage box 2 for collection, so as to facilitate subsequent recycling.

[0052] See also Figure 1-Figure 2 , a support plate 201 is fixedly arranged on one side of the storage box 2, and one end of the second half gear 511 away from the second air supply part 504 is rotatably connected to the lifting seat 512, and the lifting seat 512 is fixed on the lifting plate 513, wherein the lifting module includes a lifting box body 6 fixedly arranged on one side of the support plate 201, and a driving mechanism for driving the lifting plate 513 to rise and fall is provided in the lifting box body 6; specifically, in this embodiment, the lifting plate 513 is driven to rise and fall by the driving mechanism, and the lifting plate 513 can drive the second air supply part 504 and the second drying part 503 to move synchronously through the lifting seat 512;

[0053] In this embodiment, the drying box 1 is fixed to the storage box 2 via at least two sets of mounting frames 104 .

[0054] It should be noted that the driving mechanism may be a screw-nut transmission mechanism or a synchronous belt transmission mechanism, which is not limited in this embodiment, and it is sufficient to drive the lifting plate 513 to rise and fall in the vertical direction.

[0055] When the first drying section 503 is combined with the second drying section 503, in order to improve the heat preservation effect of the drying box 1, in this embodiment, please refer to Figure 2-Figure 4 as well as Figure 7-Figure 8 A sealed box 4 is further provided between the storage box 2 and the second drying section 503. Two sets of baffles 301 are arranged on both sides of the sealed box 4. The side walls of the drying box 1 are provided with reserved grooves 101 for engaging with the baffles 301 on both sides. The two sets of baffles 301 are symmetrically slidably arranged on the side walls of the sealed box 4. The two sets of baffles 301 are respectively provided with arc grooves 304 for engaging with the second air supply section 504. The second air supply section 504 is symmetrically provided with two sets of card grooves 303. The groove walls of the arc grooves 304 are fixed with card grooves 303. A holder 302 is provided for engaging with the slot 303; it can be explained that, based on the settings of the holder 302 and the slot 303, when the lifting module drives the second drying section 503 to rise, the second drying section 503 can simultaneously drive the baffle 301 to rise, and the baffle 301 drives the sealing box 4 to rise. When the second drying section 503 is merged with the first drying section 5, the sealing box 4 is just merged with the bottom opening of the drying box 1. At the same time, the baffle 301 is engaged with the reserved groove 101, thereby achieving the effect of sealing and heat preservation.

[0056] Also, see Figure 2 and Figure 6In order to discharge the separated liquid that falls into the sealing box 4 during solid-liquid separation into the storage box 2, in this embodiment, a plurality of groups of drainage grooves 401 are arranged in an array on the sealing box 4, and a sealing plate 402 is slidably embedded in the drainage groove 401. Guide rods 405 are fixedly arranged at both ends of the drainage groove 401, and both ends of the sealing plate 402 are slidably connected to the guide rods 405. A first spring 404 is provided on the guide rod 405, and one end of the first spring 404 is fixed to the end of the guide rod 405, and the other end is fixed to the sealing plate 402, wherein two groups of limiting plates 206 are fixedly arranged in the storage box 2, and two groups of top rods 205 corresponding to each drainage groove 401 are fixedly arranged on the limiting plate 206; it can be explained that in the natural state, each sealing plate 402 is in a position corresponding to the drainage groove 4 01 engaged state, when the second drying section 503 is in the initial position, based on the setting of the push rod 205, the push rod 205 can pass through the drainage groove 401 to lift the sealing plate 402 to separate from the drainage groove 401, and the first spring 404 is stretched to generate elastic force. At this time, the liquid after solid-liquid separation can pass through the drainage groove 401 and fall into the storage box 2. When the sealing box 4 rises with the second drying section 503, the push rod 205 loses the lifting effect on the sealing plate 402, and each first spring 404 can drive the sealing plate 402 to be embedded in the drainage groove 401 for sealing, thereby preventing hot air from being discharged from the drainage groove 401 during the drying process. At this time, the solid-liquid separated liquid can temporarily stay in the sealing box 4, and as the drying is completed and the sealing box is reset, the liquid can be discharged accordingly.

[0057] As a further solution of this embodiment, please refer to Figure 3-Figure 5 , in order to facilitate the collection of the dried ammonium molybdate crystals; a support shaft 202 is rotatably arranged on the support plate 201, a U-shaped frame 203 is fixedly arranged on one side of the support shaft 202, a collection box 3 is fixedly arranged at the end of the U-shaped frame 203, and the support shaft 202 is connected to the adjustment part that drives it to rotate, wherein a support rod 602 is also fixedly arranged on one side of the support plate 201, and a first rack 601 is fixedly arranged on the support rod 602; it can be explained that after the ammonium molybdate is dried, the second drying part 503 is reset to the initial position, and with the lifting and lowering The module continues to drive the second air supply section 504 to move downward, and the two sets of baffles 301 also move away from each other, and then drive the collecting box 3 to rotate to the bottom of the second drying section 503 through the adjustment section. As it continues to move downward, the second half gear 511 drives the second drying section 503 to flip toward the storage box 2 by engaging with the first rack 601, and stops moving after flipping 180 degrees. At this time, the ammonium molybdate crystals in the second drying section 503 can fall completely into the collecting box 3, achieving the effect of automatic material dropping.

[0058] In this embodiment, please refer to Figure 6 , Figure 7 and Figure 8, slide grooves 403 are respectively provided on the two side walls of the sealing box 4, and a limit rod 305 is slidably arranged in the slide groove 403, and a slide seat 307 fixed to the baffle 301 is slidably arranged on the limit rod 305, and a second spring 306 is provided on the limit rod 305, one end of the second spring 306 is fixed to the slide seat 307, and the other end is fixed to the groove wall; it can be explained that when the second air supply part 504 moves downward and drives the baffles 301 on both sides to move away from each other, the baffle 301 can synchronously drive the slide seat 307 to slide on the limit rod 305 to compress the second spring 306, and the second spring 306 is used for subsequently driving the baffles 301 on both sides to reset.

[0059] See also Figure 4-Figure 5 The adjusting part includes a second gear 204 fixedly arranged on the top of the support shaft 202, the second gear 204 meshes with the second rack 605, the second gear 204 is fixed to one side of the tilting bracket 604, a guide plate 606 is fixedly arranged at the bottom of the tilting bracket 604, a guide wheel 603 that rolls against the tilting bracket 604 is rotatably arranged at the bottom of the end of the lifting plate 513, a limit seat 607 is fixedly arranged on the support plate 201, a sliding rod 609 fixed to the guide plate 606 is slidably arranged in the limit seat 607, a third spring 608 is arranged on the sliding rod 609, one end of the third spring 608 is fixed to the limit seat 607, and the other end of the third spring 608 is fixed to the limit seat 607. The guide plate 606 at one end is fixed; it can be explained that when the lifting module drives the second drying section 503 to move downward from the initial position, the lifting plate 513 drives the guide wheel 603 to first squeeze the inclined bracket 604, so that the inclined bracket 604 is offset to one side, and the inclined bracket 604 drives the second rack 605 to move synchronously during the movement, and the second rack 605 drives the support shaft 202 to rotate by meshing with the second gear 204 during the movement, and the support shaft 202 drives the collection box 3 to deflect 90 degrees toward the second drying section 503 through the U-shaped frame 203, so as to be used to receive the ammonium molybdate crystals;

[0062] An ammonium molybdate dryer comprises a drying device in Example 2, and is used for solid-liquid separation of ammonium molybdate material.

[0063] In this embodiment, the drying method of the ammonium molybdate dryer comprises the following steps:

[0064] See also Figure 2-Figure 5 , the ammonium molybdate to be separated into solid and liquid is input into the second drying section 503, and the preliminary solid-liquid separation is performed through the filtrate hole 505 opened on the second drying section 503, and the filtrate falls into the storage box 2;

[0065] The lifting module drives the second drying section 503 to move into the drying box 1 and merge with the first drying section 5 to form a complete cylindrical structure (in this embodiment, sealing gaskets can be provided at the connection surfaces of the first drying section 5, the second drying section 503, the first air supply section 502 and the second air supply section 504 to improve the sealing performance during connection). At the same time, the first air supply section 502 and the second air supply section 504 merge to form a complete air supply cylinder;

[0066] The rotating part drives the first air supply part 502 to rotate. During the rotation of the first air supply part 502, the first drying part 5 and the second drying part 503 can be driven to rotate synchronously. Under the action of centrifugal force, the liquid on the ammonium molybdate can be thrown out from the filtrate hole 505 to achieve secondary solid-liquid separation.

[0067] The air delivery cylinder 501 delivers the heated air to the air supply cylinder formed by the first air supply part 502 and the second air supply part 504, and the hot air can be delivered to the first drying part 5 and the second drying part 503 through the air hole 506 to dry the ammonium molybdate;

[0068] After the drying is completed, the lifting module drives the second drying section 503 to return to the initial position;

[0069] See also Figure 5-Figure 8 , the lifting module continues to drive the second air supply part 504 to move downward, and the two sets of baffles 301 also move away from each other;

[0070] The adjusting part drives the collecting box 3 to rotate to the bottom of the second drying section 503. As the second air supply part 504 continues to move downward, the second half gear 511 drives the second drying section 503 to flip toward the storage box 2 by engaging with the first rack 601. After flipping 180 degrees, the movement stops. At this time, the ammonium molybdate crystals in the second drying section 503 can completely fall into the collecting box 3 for collection.
