Description

Technical Field

[0001] The invention relates to the technical field of sodium molybdate impurity removal, in particular to a sodium molybdate continuous crystallization impurity removal device. Background Art

[0002] Sodium molybdate, as an important inorganic chemical product, is widely used in metal surface treatment, catalyst preparation, textile printing and dyeing, pharmaceutical intermediates, and agricultural trace element fertilizers. Its purity directly affects the performance and quality of downstream products. Therefore, in the production process of sodium molybdate, the purification process is a key link to ensure product quality.

[0003] Currently, sodium molybdate is typically prepared from molybdenum concentrate or molybdenum-containing waste. A crude sodium molybdate solution is obtained through roasting, leaching, and purification processes, and then crystallization is used to obtain sodium molybdate crystals. Crystallization and impurity removal are key steps in improving the purity of sodium molybdate. In the prior art, sodium molybdate crystallization and impurity removal are often performed in an intermittent process, whereby the solution is heated and evaporated to a supersaturated state, prompting the precipitation of sodium molybdate crystals. Solid impurities are then separated from the solution using filtration or sedimentation.

[0004] After searching, the existing patent announcement number is CN214913528U. A sodium acetate crystallization and impurity removal device is used. Sodium acetate, which is similar to sodium molybdate, is melted and placed inside a material box for heating. The rotating heating plate can stir and mix the material on the one hand, so that the heating plate and the material are in full contact, thereby achieving a uniform heating effect. On the other hand, impurities in the raw material can be adsorbed on the through holes on the heating plate, thereby filtering the raw material, which is beneficial to improving the purity after crystallization. Through this structure, the material can be evenly heated, and the material can be filtered during the heating stage, which can achieve a better crystallization effect.

[0005] However, during use, the device has an open top, which can easily cause heat loss and spillage of the solution during stirring, resulting in contamination. Furthermore, cleaning the filter on the heating plate requires disassembling the entire stirring device (including the heating plate), which is cumbersome. Furthermore, the heating plate is electrically connected, and frequent disassembly and assembly can easily loosen the connection, resulting in poor sealing and ultimately safety hazards such as leakage. Furthermore, when heating the solution, the device requires mixing the powdered material with water through a separate process before adding it to the device for heating, stirring, and impurity removal. This lacks continuity and requires long periods of downtime for each cycle, reducing impurity removal efficiency.

[0006] Therefore, developing a sodium molybdate crystallization impurity removal device that can achieve continuous production, has high impurity removal efficiency, and is easy to maintain is of great significance for improving the automation level of sodium molybdate production, reducing costs, and improving product quality.

DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0030] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, a sodium molybdate continuous crystallization and impurity removal device according to the present invention includes a support plate 1, a heating mechanism 2 is installed on the support plate 1, the heating mechanism 2 includes a storage box 201, the storage box 201 is installed on the top of the support plate 1, an impurity removal mechanism 3 is installed on the storage box 201, a cleaning mechanism 5 is installed on the impurity removal mechanism 3, and a mixing mechanism 7 is installed on the storage box 201.

[0031] Specifically, such as Figure 1 and Figure 3 As shown, a plurality of equidistantly distributed heating tubes 203 are installed on the inner wall of the bottom of the storage box 201, and a discharge pipe 202 is installed at one end of the bottom of the storage box 201. The installation of the heating tube 203 facilitates uniform heating of the liquid inside the storage box 201, so that the liquid can be fully melted, which is convenient for subsequent impurity removal. The discharge of the impurity-removed liquid is achieved through the control of the discharge pipe 202, which is convenient for subsequent crystallization.

[0032] Specifically, such as Figure 3 、 Figure 5 、 Figure 6 and Figure 7 As shown, the impurity removal mechanism 3 includes a rotating shaft 302, and the rotating shaft 302 is rotatably connected to the center of the storage box 201 through a connecting shaft 307. A plurality of mounting brackets 303 are installed on the rotating shaft 302, and a connecting plate 306 is installed on the plurality of mounting brackets 303. Filter screens 305 are installed at both ends of the connecting plate 306. The connecting shaft 307 cooperates to facilitate the rotational connection of the rotating shaft 302. The installation of the rotating shaft 302 facilitates the connection of the plurality of mounting brackets 303. The installation of the mounting bracket 303 facilitates the installation of the connecting plate 306, thereby realizing the connection of the filter screen 305. As a result, when the rotating shaft 302 rotates, the filter screen 305 salvages debris from the liquid inside the storage box 201, so that the debris adheres to the filter screen 305 and is cleaned.

[0033] Specifically, such as Figure 1 、 Figure 3 and Figure 5 As shown, a driving motor 301 is installed at the center of one end of the storage box 201. The output shaft of the driving motor 301 is connected to the connecting shaft 307. The two connecting shafts 307 are fixedly connected to the two ends of the rotating shaft 302. The installation of the driving motor 301 facilitates the drive control of the connecting shaft 307, thereby realizing the rotation control of the rotating shaft 302 by the connecting shaft 307, thereby realizing stirring and impurity removal.

[0034] Specifically, such as Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7As shown, the cleaning mechanism 5 includes a through slot 501, a through slot 501 is provided on the top of the storage box 201, the bottom of the through slot 501 extends to the inside of the storage box 201, a baffle 502 is slidably connected to the inside of the top of the storage box 201 through a slot 504, one end of the baffle 502 extends to the inside of the through slot 501, the bottom of the baffle 502 is flush with the side wall of the storage box 201, and a plurality of mounting brackets 303 are installed on the inside of the bottom of the push plate 505, and the push plate 505 is connected to the inside of the storage box 201 through a plurality of compression springs. The spring 506 is slidably connected to the inner side of the bottom of the mounting bracket 303, the connecting plate 306 is slidably connected to the inside of the mounting bracket 303, the bottom of the connecting plate 306 is in conflict with the push plate 505, and the top of the connecting plate 306 is rotatably connected to multiple guide wheels 304, and the multiple guide wheels 304 are respectively connected to the inner wall of the storage box 201 in a rolling manner. The opening of the through slot 501 facilitates the connecting plate 306 to slide out, and the insertion of the baffle 502 is facilitated by the matching of the slot 504, so as to realize the alignment. The through slot 501 is blocked, which is conducive to the connection plate 306 not sliding out when rotating inside the storage box 201. Under the cooperation of the guide wheel 304, the connection plate 306 and the storage box 201 rotate smoothly without wear. By pulling out the baffle 502, the through slot 501 is opened. When the shaft 302 drives the connection plate 306 to move to one side of the through slot 501, the connection plate 306 will slide out under the resistance of the push plate 505, which is convenient for replacing the filter screen 305 on the connection plate 306. Cleaning and operation are more convenient. After cleaning and replacement, the connecting plate 306 is inserted into the mounting bracket 303, and then the baffle 502 is inserted. The end of the baffle 502 slides down against the connecting plate 306 and the guide wheel 304, so that the connecting plate 306 enters the inside of the storage box 201, and then the rotating shaft 302 is rotated to make the next connecting plate 306 correspond to the through slot 501, and then the baffle 502 is taken out to make the connecting plate 306 pop out for replacement.

[0035] Specifically, such as Figure 4 and Figure 6 As shown, one end of the baffle 502 is an arc-shaped structure, and a handle 503 is installed at the other end of the baffle 502. The mounting frame 303 is a "sun"-shaped structure. The arc-shaped structure design at one end of the baffle 502 facilitates the baffle 502 to contact the connecting plate 306 and the guide wheel 304 when inserted into the slot 504, so that the connecting plate 306 enters the inner side of the storage box 201, which is convenient for closing the through groove 501. The installation of the handle 503 facilitates the drive control of the baffle 502, and at the same time enables the two filters 305 to leak out at both ends of the mounting frame 303, thereby realizing the salvage and cleaning of debris in the liquid.

[0036] Specifically, such as Figure 1 、 Figure 2 and Figure 10As shown, the mixing mechanism 7 includes a connecting seat 701, a connecting seat 701 is installed at the end of the storage box 201, and a stirring barrel 702 is installed on the connecting seat 701. The stirring barrel 702 is rotatably connected to a stirring rod 704, and the bottom of the stirring rod 704 extends to the outside of the bottom of the stirring barrel 702. The connecting shaft 307 at the end of the rotating shaft 302 extends to the outside of the storage box 201. Bevel gears 705 are respectively installed on the stirring rod 704 and the connecting shaft 307. The two bevel gears 705 are vertically meshed. The installation of the connecting seat 701 is conducive to the installation of the stirring barrel 702. The installation of the stirring barrel 702 is realized by the installation of the stirring barrel 702. Through the rotation of the rotating shaft 302 and the connecting shaft 307, with the cooperation of the bevel gear 705, the stirring rod 704 can continuously rotate inside the stirring barrel 702, which is conducive to adding water to the material inside the stirring barrel 702 and stirring it. When the stirred liquid level reaches the specified position, it is transported to the storage box 201 for heating and impurity removal.

[0037] Specifically, such as Figure 2 and Figure 10 As shown, the mixing barrel 702 is connected to the storage box 201 through a feed pipe 703, and a plurality of shovels 706 are slidably connected to the inner side of the bottom of the mixing barrel 702. One end of the plurality of shovels 706 is connected to the outer side of the bottom of the stirring rod 704. The shovels 706 are an arc-shaped structure, and the top of the mixing barrel 702 is a trumpet-shaped structure. The installation of the feed pipe 703 is conducive to the control of the liquid delivery after stirring, so that the liquid is introduced into the storage box 201 through the feed pipe 703 after reaching a certain capacity for heating and impurity removal. The installation of the shovel 706 is conducive to the rotation of the stirring rod 704. The shovel 706 can flip the sediment at the bottom of the mixing barrel 702 downward to make the stirring uniform. The trumpet design on the top of the mixing barrel 702 facilitates loading.

[0038] Specifically, such as Figure 10 As shown, a feeding mechanism 8 is installed on the mixing barrel 702, and the feeding mechanism 8 includes a partition 801. The partition 801 is fixedly connected to the inner side of the top of the mixing barrel 702, and a square discharge chute 802 is provided on the partition 801. The top of the stirring rod 704 is rotatably connected to the center of the top of the partition 801. A scraper 803 is installed on the top of the stirring rod 704. The scraper 803 is an arc-shaped structure, and the bottom of the scraper 803 is slidably connected to the top of the partition 801. The installation of the partition 801 facilitates the placement of materials on the top of the mixing barrel 702. The rotation of the stirring rod 704 facilitates the scraper 803 to push the materials to turn over, and allows the materials to pass through the discharge chute 802 into the bottom inner side of the mixing barrel 702 for stirring, thereby realizing quantitative feeding.

[0039] Specifically, such as Figure 1 、 Figure 2 、 Figure 10 、 Figure 11 and Figure 12As shown, a water inlet mechanism 9 is installed on the mixing barrel 702, and the water inlet mechanism 9 includes a support frame 901, a support frame 901 is installed on the top of the mixing barrel 702, a cylinder 904 is installed on the top of the support frame 901, a water inlet pipe 902 is installed on the support frame 901, a delivery pipe 906 is slidably connected to the inside of the stirring rod 704, and the delivery pipe 906 is a hexagonal structure with a closed bottom.

The top of the connecting pipe 905 is rotatably connected to the rotary joint 903, and the top of the rotary joint 903 is fixedly connected to the output shaft of the cylinder 904. The water inlet pipe 902 is connected to one side of the rotary joint 903 The connection is facilitated by the installation of the support frame 901, which is conducive to the connection of the cylinder 904 and the water inlet pipe 902. Through the cooperation of the connecting pipe 905, the cylinder 904 pulls the delivery pipe 906, and the delivery pipe 906 is located at the top of the drainage hole 910. The spray hole 907 on the delivery pipe 906 is blocked by the stirring rod 704. The water inside the water inlet pipe 902 is introduced into the delivery pipe 906 through the rotary joint 903 and the connecting pipe 905. The installation of the rotary joint 903 facilitates the free rotation of the connecting pipe 905 at the bottom of the output shaft of the cylinder 904. At the same time, the water inside the water inlet pipe 902 can be introduced into the connecting pipe 905. Through the work of the cylinder 904, the cylinder 904 drives the connecting pipe 905 to slide down, and the delivery pipe 906 slides down to a certain position inside the stirring rod 704. The spray hole 907 on the delivery pipe 906 is connected with the drainage hole 910, which is conducive to the introduction of water into the mixing barrel 702 to achieve mixing and stirring with the materials.

[0040] Specifically, such as Figure 10 and Figure 11 As shown, a control panel 908 is provided at the bottom of the partition 801, and the control panel 908 contacts the bottom of the discharge chute 802. A pressure rod 909 is installed on the top of the control panel 908, and the top of the pressure rod 909 is fixedly connected to the outer side of the rotary joint 903. The installation of the control panel 908 is convenient for controlling the opening and closing of the discharge chute 802. When the drainage is controlled by the cylinder 904, the rotary joint 903 drives the pressure rod 909 to contact the control panel 908. The control panel 908 slides down to a certain position to open the discharge chute 802, so that the material can be discharged and mixed with water, thereby playing a role in synchronous control of the material and water.

[0041] Specifically, such as Figure 6 、 Figure 7 and Figure 8As shown, a connecting mechanism 4 is installed on the rotating shaft 302, and the connecting mechanism 4 includes a mounting groove 403. A plurality of mounting grooves 403 are provided on the outer side of the rotating shaft 302. The bottoms of the plurality of mounting brackets 303 are respectively engaged with the interior of the plurality of mounting grooves 403. A protrusion 401 is respectively installed on the inner sides of both ends of the bottom of the plurality of mounting brackets 303. The protrusion 401 is slidably connected to the interior of the mounting bracket 303 through the interference spring 402. One end of the protrusion 401 extends to the outer side of the mounting bracket 303. One end of the protrusion 401 is a hemispherical structure. A plurality of grooves 404 are provided on the inner sides of both ends of the rotating shaft 302. One side of the groove 404 is connected to the interior of the mounting groove 403. One end of the protrusion 401 interferes with the inside of the groove 404. The opening of the mounting groove 403 facilitates the engagement and connection between the mounting bracket 303 and the rotating shaft 302. At the same time, when the mounting bracket 303 is inserted into the mounting groove 403, the protrusion 401 is interfered with and freed from the elastic force of the interference spring 402 and contracts. After the mounting bracket 303 is stably engaged with the inside of the mounting groove 403, the protrusion 401 interferes with the inside of the groove 404 under the elastic force of the interference spring 402, thereby limiting the mounting bracket 303. By pulling the mounting bracket 303 with a certain pulling force, the protrusion 401 is pushed to interfere and contract, thereby realizing the disassembly of the mounting bracket 303.

[0042] Specifically, such as Figure 6 、 Figure 7 and Figure 9 As shown, a locking mechanism 6 is installed on the inner side of the bottom of multiple mounting frames 303, and the locking mechanism 6 includes a transmission rod 602. Symmetrical transmission rods 602 are respectively installed on the inner sides of both ends of the bottom of multiple mounting frames 303. The transmission rods 602 are slidably connected to the inside of the mounting frame 303 through a return spring 603. The opposite ends of the two transmission rods 602 extend to the end of the protrusion 401 respectively. The opposite ends of the two transmission rods 602 are hemispherical structures. A driving plate 601 is slidably connected at the midline of the inner bottom of multiple mounting frames 303. The bottom of the driving plate 601 is a triangular structure. The top of the driving plate 601 is vertically connected to the bottom of the push plate 505. The opposite ends of the two transmission rods 602 respectively conflict with the two sides of the driving plate 601. , which is conducive to the limit control of the protrusion 401. Under the resistance of the return spring 603, the transmission rod 602 is always away from the protrusion 401, so that the protrusion 401 can slide, which is convenient for the disassembly and assembly of the mounting frame 303. After the connecting plate 306 and the internal installation of the mounting frame 303 are stably installed, the push plate 505 is squeezed and slides down, and the push plate 505 drives the driving plate 601 to slide down. The driving plate 601 resists the two transmission rods 602, and the transmission rod 602 slides away from the elastic force of the return spring 603. The transmission rod 602 resists the protrusion 401, and the protrusion 401 cannot slide, so that the mounting frame 303 and the rotating shaft 302 are firmly installed. After disassembly through the connecting plate 306, it is convenient for the driving plate 601 to reset, and the protrusion 401 can slide, so that the mounting frame 303 can be pulled and disassembled.

[0043] When the present invention is in use, firstly, the power is turned on to make the multiple heating tubes 203 inside the storage box 201 work, and the electric heating wire inside the heating tube 203 converts the electrical energy into thermal energy, thereby heating the liquid inside the storage box 201, so that the liquid can be fully melted, which is convenient for subsequent impurity removal, and the impurity-removed liquid is discharged through the control of the discharge pipe 202, which is convenient for subsequent crystallization, and the connection of the rotating shaft 302 is facilitated by the cooperation of the connecting shaft 307. The installation of the rotating shaft 302 is convenient for connecting the multiple mounting racks 303. The installation of the mounting rack 303 is convenient for installing the connecting plate 306, so as to realize the connection of the filter screen 305, and then when the rotating shaft 302 rotates, the filter screen 305 salvages the impurities from the liquid inside the storage box 201, so that the impurities are attached to the filter screen 305. The cleaning is facilitated by the installation of the driving motor 301 to drive the connecting shaft 307 and thereby realize the rotation control of the connecting shaft 307 on the rotating shaft 302 to realize stirring and removing impurities. The opening of the through slot 501 is conducive to the connecting plate 306 being able to slide out, and the insertion of the baffle 502 through the slot 504 is conducive to the blocking of the through slot 501, which is conducive to the connecting plate 306 not sliding out when the material storage box 201 rotates. Under the cooperation of the guide wheel 304, the connecting plate 306 and the material storage box 201 rotate smoothly without wear. By pulling out the baffle 502 and opening the through slot 501, when the rotating shaft 302 drives the connecting plate 306 to move to one side of the through slot 501, the connecting plate 306 will slide out under the resistance of the push plate 505, which is convenient for After the filter screen 305 is replaced and cleaned, the operation is more convenient. After cleaning and replacement, the connecting plate 306 is inserted into the mounting bracket 303, and then the baffle 502 is inserted. The end of the baffle 502 contacts the connecting plate 306 and the guide wheel 304 and slides down, so that the connecting plate 306 enters the inner side of the storage box 201. Then the rotating shaft 302 is rotated to make the next connecting plate 306 correspond to the through slot 501, and then the baffle 502 is taken out, so that the connecting plate 306 pops out for replacement. The arc structure design at one end of the baffle 502 is conducive to the baffle 502 being inserted into the slot 504 to contact the connecting plate 306 and the guide wheel 304, so that the connecting plate 306 enters the inner side of the storage box 201, which is convenient for closing the through slot 501. The plate 502 is driven and controlled, and at the same time, the two filter screens 305 can leak out at both ends of the mounting bracket 303, so that the debris in the liquid can be salvaged and cleaned. The opening of the mounting groove 403 is conducive to the engagement and connection between the mounting bracket 303 and the rotating shaft 302. At the same time, when the mounting bracket 303 is inserted into the mounting groove 403, the protrusion 401 is resisted and freed from the elastic force of the resistance spring 402 and shrinks. After the mounting bracket 303 is stably engaged with the inside of the mounting groove 403, the protrusion 401 is in resistance with the inside of the groove 404 under the elastic force of the resistance spring 402, which plays a role in limiting the mounting bracket 303. The mounting bracket 303 is pulled by a certain pulling force, and the protrusion 401 is pushed to resist and shrink, thereby realizing the disassembly of the mounting bracket 303. The installation of the transmission rod 602 is conducive to the limit control of the protrusion 401.Under the resistance of the return spring 603, the transmission rod 602 is always away from the protrusion 401, so that the protrusion 401 can slide, which is convenient for the disassembly and assembly of the mounting frame 303. After the connecting plate 306 is stably installed inside the mounting frame 303, the push plate 505 is squeezed and slides down, and the push plate 505 drives the driving plate 601 to slide down. The driving plate 601 resists the two transmission rods 602, and the transmission rod 602 slides away from the elastic force of the return spring 603. The transmission rod 602 resists the protrusion 401, and the protrusion 401 cannot slide, so that the mounting frame 303 is firmly installed with the rotating shaft 302. After the connecting plate 306 is disassembled, it is convenient for the driving plate 601 to reset, and the protrusion 401 can slide, so that the mounting frame 303 is pulled and disassembled, and the installation of the connecting seat 701 is beneficial to the stirring. The barrel 702 is installed. By installing the mixing barrel 702, the material can be put into the mixing barrel. By rotating the rotating shaft 302 and the connecting shaft 307, the stirring rod 704 can rotate continuously inside the mixing barrel 702 with the cooperation of the bevel gear 705, which is conducive to adding water to the material inside the mixing barrel 702 and stirring it. When the stirred liquid level reaches the specified position, it is transported to the storage box 201 for heating and impurity removal. The installation of the feeding pipe 703 is conducive to the control of the liquid after stirring, so that the liquid is introduced into the storage box 201 for heating and impurity removal after reaching a certain capacity through the feeding pipe 703. The installation of the shovel plate 706 is conducive to the rotation of the stirring rod 704. The shovel plate 706 can flip the sediment at the bottom of the mixing barrel 702 downward to make the stirring uniform. The bell mouth design on the top of the barrel 702 is convenient for loading. The installation of the partition 801 is conducive to putting materials on the top of the mixing barrel 702. The rotation of the stirring rod 704 is conducive to the scraper 803 pushing the material to turn over, and the material enters the bottom inner side of the mixing barrel 702 through the discharge chute 802 for stirring, thereby realizing quantitative loading. The installation of the support frame 901 is conducive to the connection of the cylinder 904 and the water inlet pipe 902. Through the cooperation of the connecting pipe 905, the cylinder 904 pulls the delivery pipe 906. The delivery pipe 906 is located at the top of the drain hole 910. The spray hole 907 on the delivery pipe 906 is blocked by the stirring rod 704. The water inside the water inlet pipe 902 is introduced into the delivery pipe 906 through the rotary joint 903 and the connecting pipe 905. The installation is conducive to the free rotation of the connecting pipe 905 at the bottom of the output shaft of the cylinder 904, and at the same time, the water inside the water inlet pipe 902 can be introduced into the connecting pipe 905. Through the operation of the cylinder 904, the cylinder 904 drives the connecting pipe 905 to slide down, and the delivery pipe 906 slides down to a certain position inside the stirring rod 704. The spray hole 907 on the delivery pipe 906 is connected with the drainage hole 910, which is conducive to the introduction of water into the mixing barrel 702 to achieve mixing with the materials. The installation of the control board 908 is conducive to the opening and closing control of the discharge chute 802. When the drainage is controlled by the cylinder 904, the rotary joint 903 drives the pressure rod 909 to contact the control board 908. The control board 908 slides down to a certain position to open the discharge chute 802, so that the materials can be discharged and mixed with the water.It plays the role of synchronous control of materials and water.
