Description

Technical Field

[0001] This utility model relates to the field of refined zirconium tetrachloride collection technology, specifically to a refined zirconium tetrachloride collection device. Background Technology

[0002] Zirconium tetrachloride purification refers to the process of removing impurities from crude zirconium tetrachloride to produce pure zirconium tetrachloride. Zirconium tetrachloride obtained by chlorinating zirconium carbide, zircon, or zirconium dioxide still contains considerable amounts of impurities such as FeCl3, AlCl3, TiCl4, SiCl4, ZrOCl4, and carbon powder, which must be thoroughly removed before it can be used as a raw material for the production of sponge zirconium.

[0003] Existing zirconium tetrachloride collection devices purify crude zirconium tetrachloride by first adding it into the furnace, then adding other materials such as sodium chloride and potassium chloride, and finally heating the furnace to allow a reaction.

[0004] However, existing refined zirconium tetrachloride collection devices require the crude zirconium tetrachloride to be added into the furnace in batches at regular intervals when purifying crude zirconium tetrachloride. Moreover, the weight of the crude zirconium tetrachloride needs to be controlled each time it is added, which wastes time by weighing the crude zirconium tetrachloride in advance.

The weight sensor weighs the material at the top of the rotating plates, and the controller activates the telescopic rod to rotate the two rotating plates, allowing the material to be discharged through the second electric valve.

[0007] Preferably, the inner wall of the furnace body is fixedly connected to a heat insulation plate and is located below the box body. Support legs are fixedly connected to the four corners of the bottom of the furnace body, and a feed inlet is provided on the outer wall of the furnace body.

[0008] Preferably, the material control unit includes: a storage bucket, fixedly connected to the top of the cover by bolts; a conical hopper, fixedly connected to the inner wall of the storage bucket and extending into the interior of the cover; a servo motor, fixedly connected to the top of the inner wall of the cover, with its output end penetrating through the outer wall of the conical hopper via a sealed bearing; and a discharge plate, in a cross shape, with one end fixedly connected to the output end of the servo motor and the other end rotatably connected to the inner wall of the conical hopper via a sealed bearing; wherein, the storage bucket stores the material, the conical hopper houses the servo motor and the discharge plate, and the output end of the servo motor drives the discharge plate to rotate, controlling the material discharge speed.

[0012] Beneficial effects

[0013] This invention provides a refined zirconium tetrachloride (ZTCH) collection device. It offers the following advantages: Through the cooperation of the housing, rotating plates, and a weight sensor, when crude ZTCH needs to be added to the furnace, the material control unit is activated. The crude ZTCH falls onto the top of the receiving plate, where the weight sensor weighs it and transmits the weight information to the controller. The controller then controls a telescopic rod, which rotates two rotating plates, creating a gap between them, i.e., between the two receiving plates. The crude ZTCH is then added to the furnace through this gap, eliminating the need for manual addition and allowing for the weighing of the added material.

[0014] Through the cooperation between the conical hopper, servo motor, and feeding plate, when material is fed into the box, the servo motor is started, and the output of the servo motor drives the feeding plate to rotate. The rotation of the feeding plate can feed the material into the box in batches. When the weight sensor senses that the specified value has been reached, the controller controls the servo motor to stop working, that is, the feeding plate will not continue to rotate and cannot feed material into the box, thus achieving the purpose of accurate weighing.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Existing zirconium tetrachloride collection devices require the crude zirconium tetrachloride to be added into the furnace in batches at regular intervals when purifying crude zirconium tetrachloride. Moreover, the weight of the crude zirconium tetrachloride needs to be controlled each time it is added, which wastes time by weighing the crude zirconium tetrachloride in advance.

[0022] In view of this, the present invention provides a refined zirconium tetrachloride collection device. Through the cooperation between the box, the rotating plate and the weight sensor, when crude zirconium tetrachloride needs to be added into the furnace, the material control unit is activated, and the crude zirconium tetrachloride will fall to the top of the rotating plate. Then the weight sensor weighs it and transmits the weighing information to the controller. The controller controls the telescopic rod, which drives the two rotating plates to rotate, creating a gap between the two rotating plates. The crude zirconium tetrachloride is then added into the furnace through the gap, achieving the purpose of adding without manual intervention and weighing the added weight.

[0023] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0024] Example 1: By Figure 1-4 It is known that a zirconium tetrachloride collection device includes a furnace body 1, a cover 11 fixedly connected to the top of the furnace body 1 by bolts, a collection mechanism 4 arranged below the furnace body 1, and a metering device 2 arranged inside the furnace body 1. The metering device 2 includes: a housing 21 fixedly connected to the inner wall of the cover 11; two rotating plates 22, both rotatably connected to the inner wall of the housing 21 by pins, with their adjacent sides touching; a receiving plate 23 arranged above the rotating plates 22; and a weight sensor 24 installed between the receiving plate 23 and the rotating plates 22. The telescopic rod 25 is rotatably connected to the bottom of the inner wall of the box 21 via a pin, and its output end is rotatably connected to the bottom of the rotating plate 22 via a pin; the second electric valve 26 is installed at the bottom of the box 21 and penetrates the top of the heat insulation plate 12; the controller 27 is installed on the front of the cover 11; the material control part 28 is located above the cover 11; wherein, the material on the top of the rotating plate 22 is weighed by the weight sensor 24, and the controller 27 is controlled to start the telescopic rod 25, so that the two rotating plates 22 rotate and the material is discharged through the second electric valve 26;

[0025] In the specific implementation process, it is worth noting that the specific models of the weight sensor 24, the second electric valve 26, and the controller 27 are not described here. When using the molten salt purification method to purify crude zirconium chloride, the crude zirconium chloride needs to be added into the furnace body 1 in batches according to the time. After the material falls to the top of the receiving plate 23, the weight sensor 24 weighs the material and transmits the weighing information to the controller 27. The controller 27 controls the telescopic rod 25, which drives the two rotating plates 22 to rotate, so that a gap appears between the two rotating plates 22, that is, between the two receiving plates 23. The crude zirconium tetrachloride is added into the furnace body 1 through the gap, achieving the purpose of not requiring manual addition and being able to weigh the added weight.

[0026] Furthermore, the inner wall of the furnace body 1 is fixedly connected with a heat insulation plate 12, which is located below the box body 21. Support legs 15 are fixedly connected to the four corners of the bottom of the furnace body 1, and a feed inlet 16 is opened on the outer wall of the furnace body 1.

[0027] In the specific implementation process, it is worth noting that by setting the heat insulation plate 12, the damage to the weight sensor 24 and telescopic rod 25 inside the cover 11 can be reduced, and other materials required for purifying crude zirconium tetrachloride can be put into the furnace body 1 through the feed port 16.

[0028] Furthermore, the material control unit 28 includes: a storage bin 281, which is fixedly connected to the top of the cover 11 by bolts; a conical hopper 282, which is fixedly connected to the inner wall of the storage bin 281 and extends into the interior of the cover 11; a servo motor 283, which is fixedly connected to the top of the inner wall of the cover 11, and whose output end passes through the outer wall of the conical hopper 282 through a sealed bearing; and a discharge plate 284, which is cross-shaped, with one end fixedly connected to the output end of the servo motor 283 and the other end rotatably connected to the inner wall of the conical hopper 282 through a sealed bearing; wherein, the storage bin 281 stores the material, the conical hopper 282 mounts the servo motor 283 and the discharge plate 284, and the output end of the servo motor 283 drives the discharge plate 284 to rotate, thereby controlling the material discharge speed;

[0029] In the specific implementation process, it is worth noting that when crude zirconium tetrachloride is put into the inside of the box 21, the servo motor 283 is started. The output of the servo motor 283 drives the feeding plate 284 to rotate. The rotation of the feeding plate 284 can put the material into the inside of the box 21 in batches. When the weight sensor 24 senses that the specified value has been reached, the controller 27 controls the servo motor 283 to stop working, that is, the feeding plate 284 does not continue to rotate and cannot put material into the inside of the box 21, thus achieving the purpose of accurate weighing.

[0030] Specifically, when using this refined zirconium tetrachloride collecting device, after the material falls to the top of the receiving plate 23, the weight sensor 24 weighs the material and transmits the weighing information to the controller 27. The controller 27 controls the telescopic rod 25, which drives the two rotating plates 22 to rotate, creating a gap between the two rotating plates 22, i.e., between the two receiving plates 23. The crude zirconium tetrachloride is then fed into the furnace body 1 through the gap, achieving the purpose of feeding without manual intervention and allowing for weighing of the fed material. When crude zirconium tetrachloride is fed into the box 21, the servo motor 283 is activated. The output of the servo motor 283 drives the feeding plate 284 to rotate. The rotation of the feeding plate 284 feeds the material into the box 21 in batches. When the weight sensor 24 senses that the specified value has been reached, the controller 27 controls the servo motor 283 to stop working, i.e., the feeding plate 284 stops rotating and cannot feed material into the box 21, thus achieving the purpose of accurate weighing.

[0031] Example 2: From Figure 1-4 It can be seen that a baffle plate 13 is fixedly connected to the inner wall of the furnace body 1 and is located below the heat insulation plate 12. A first electric valve 14 is installed at the bottom of the baffle plate 13.

[0032] In the specific implementation process, it is worth noting that after the crude zirconium chloride reacts with other materials inside the furnace body 1, the baffle plate 13 can block the materials and divide the furnace body 1 into two parts. The first electric valve 14 is closed to allow the various materials to react fully. The first electric valve 14 is opened to allow a portion of the materials to fall to the bottom of the inner wall of the furnace body 1, where the materials evaporate. Finally, the molten salt is replaced intermittently. Every hour, 10% to 20% of the weight of the material at the top of the baffle plate 13 is fed into the molten salt at the bottom of the inner wall of the furnace body 1 through the first electric valve 14. This process is repeated continuously for continuous discharge.

[0033] Furthermore, a heating unit 3 is provided inside the furnace body 1. The heating unit 3 includes: a resistance wire 31, which is installed on the inner wall of the furnace body 1; and a temperature controller 32, which is installed on the front of the furnace body 1. The temperature controller 32 controls the resistance wire 31 to heat the inside of the furnace body 1 to react and purify the crude zirconium tetrachloride.

[0034] In the specific implementation process, it is worth noting that resistance wires 31 are installed on both the inner wall and bottom of the furnace body 1. The resistance wires 31 on the inner wall of the furnace body 1 heat the space above the baffle plate 13 to 290 to 350 degrees Celsius, causing the crude zirconium chloride to react with other materials. The reacted material falls to the bottom of the inner wall of the furnace body 1 through the first electric valve 14. At this time, the resistance wires 31 at the bottom of the inner wall of the furnace body 1 heat the space below the baffle plate 13 to 500 to 650 degrees Celsius, causing the zirconium tetrachloride to evaporate. The baffle plate 13 has a certain heat insulation effect, preventing the baffle plate from blocking the heat. The temperature below the material plate 13 is too high, which is transmitted to the space above the baffle plate 13. The temperature controller 32 consists of a control panel, a processor, and a temperature sensor. The operator first presets the temperature through the control panel. The temperature sensor is installed inside the furnace body 1 to identify the temperature inside the furnace body 1 and transmits the signal to the processor. The processor controls the resistance wire 31 to heat the furnace body 1 according to the temperature preset by the operator to ensure that the temperature inside the furnace body 1 is suitable. In this embodiment, the specific models of the temperature controller 32 and the resistance wire 31 are not limited, as long as they meet the technical solution described in this embodiment.

[0035] Furthermore, the collection mechanism 4 includes: a discharge pipe 41, one end of which is connected to the bottom of the furnace body 1; a third electric valve 42, which is installed at the end of the discharge pipe 41 away from the furnace body 1; a collection box 43, which is fixedly connected between the four support legs 15 and connected to the end of the third electric valve 42 away from the discharge pipe 41; and a condenser pipe 44, which is installed inside the collection box 43; wherein, the zirconium tetrachloride gas evaporated and purified inside the furnace body 1 enters the collection box 43 through the discharge pipe 41 and the third electric valve 42, and the zirconium tetrachloride gas is converted into a solid state through the condenser pipe 44;

[0036] In the specific implementation process, it is worth noting that after the zirconium tetrachloride is evaporated and converted into a gas, the third electric valve 42 is opened to allow the gas to flow into the collection box 43. The gas passes through the condenser 44 and is converted into a solid. The condenser 44 is connected to an external condensate circulation device to ensure that cold water flows inside the condenser 44 for condensing the incoming gas. After the conversion is complete, the purified zirconium tetrachloride is collected by opening the cover door on the front of the collection box 43. A small amount of purified zirconium tetrachloride may remain on the surface of the condenser 44, which can be scraped off. A filter device is installed at the end of the third electric valve 42 that is connected to the collection box 43 to treat the waste gas other than purified zirconium tetrachloride in the gas, so as to achieve the effect of precise purification.

[0037] Specifically, based on the above-mentioned Embodiment 1, after the crude zirconium chloride reacts with other materials inside the furnace body 1, the baffle plate 13 can block the materials and divide the furnace body 1 into two parts. After the first electric valve 14 is closed to allow the various materials to react fully, the first electric valve 14 is opened to allow a portion of the materials to fall to the bottom of the inner wall of the furnace body 1, where the materials evaporate. Finally, the molten salt is intermittently replaced. Every hour, 10% to 20% of the weight of the material at the top of the baffle plate 13 is fed into the molten salt at the bottom of the inner wall of the furnace body 1 through the first electric valve 14. This process is repeated continuously for continuous discharge. Resistance wires 31 are installed on both the inner wall and the bottom of the inner wall of the furnace body 1. The resistance wires 31 on the inner wall of the furnace body 1 heat the space above the baffle plate 13 to 290 to 350 degrees Celsius, allowing the crude zirconium chloride to react with other materials. The reacted material falls to the inner wall of the furnace body 1 through the first electric valve 14. At the bottom, the resistance wire 31 at the bottom of the inner wall of the furnace body 1 heats the space below the baffle plate 13 to 500 to 650 degrees Celsius, causing zirconium tetrachloride to evaporate. The baffle plate 13 has a certain heat insulation effect, preventing the temperature below the baffle plate 13 from being too high and being transferred to the space above the baffle plate 13. After evaporation, the zirconium tetrachloride is converted into gas. The third electric valve 42 is opened, allowing the gas to flow into the collection box 43. The gas passes through the condenser tube 44, which converts it into a solid. Cold water flows inside the condenser tube 44 to condense the incoming gas. After complete conversion, the purified zirconium tetrachloride is collected by opening the cover door on the front of the collection box 43. A small amount of purified zirconium tetrachloride may remain on the surface of the condenser tube 44, which can be scraped off. A filter device is installed at the end of the third electric valve 42 connected to the collection box 43 to treat the waste gas other than purified zirconium tetrachloride, achieving a precise purification effect.
