Description

Technical Field

[0001] This utility model relates to the field of ammonium paratungstate processing technology, specifically to an oxidation calcination device for ammonium paratungstate processing. Background Technology

[0002] Ammonium paratungstate, also known as ammonium metatungstate, is an inorganic chemical product with the molecular formula H8N2O4W and a molecular weight of 283.9145. It is used as a raw material for manufacturing other tungsten compounds and metallic tungsten. The disadvantages of ammonium paratungstate are that it irritates the eyes, respiratory system, and skin. In the production process of ammonium paratungstate, it is necessary to carry out oxidation and calcination treatment, which requires the oxidation and calcination equipment to have very good usability, for example;

[0003] Authorized announcement number CN214765921U provides a neodymium iron boron waste oxidation and calcination device, including: a dust removal mechanism, which includes a dust removal box disposed on both sides of the upper part of the main body; the dust removal box has a vertically arranged mounting plate for fixing and installing connecting pipes and a filter plate for filtering dust inside the dust removal box; a first fan disposed on the inner wall of the dust removal box and an air outlet hole disposed on the dust removal box on one side of the filter plate; multiple connecting pipes are provided, and a suction hood for absorbing dust and a second fan for drawing dust into the connecting pipe are provided on the connecting pipes; the suction hood is disposed inside the main body, and the second fan is disposed between the mounting plate and the filter plate; by setting up a dust removal mechanism, the first fan, the second fan and the filter plate are used to adsorb and treat the dust generated by waste crushing, avoiding dust from adhering to the inner wall of the main body, thus improving the working efficiency of the operator.

[0004] The existing technical solutions described above have the following drawbacks: the existing oxidation calcination devices are not convenient for uniformly feeding ammonium paratungstate raw materials during use, which greatly reduces the feeding and processing efficiency of the device and increases the labor intensity of operators. At the same time, they do not have a certain exhaust gas filtration and treatment function, which makes it easy for exhaust gas to carry a large number of ammonium paratungstate raw material particles to the outside and affect the environment outside the device. Therefore, this utility model provides an oxidation calcination device for ammonium paratungstate processing to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide an oxidation calcination device for processing ammonium paratungstate, in order to solve the problems mentioned in the background art, which are that it is not convenient to uniformly feed ammonium paratungstate raw materials during use, resulting in a significant reduction in the feeding and processing efficiency of the device and an increase in the labor intensity of operators. At the same time, the device does not have a certain exhaust gas filtration and treatment function, which causes the exhaust gas to easily carry a large number of ammonium paratungstate raw material particles to the outside and discharge them to the outside, thus affecting the environment outside the device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an oxidation calcination apparatus for processing ammonium paratungstate, comprising: a shell, and a feeding rack disposed on the upper side of the shell, and further comprising:

[0007] A storage rack is installed on the upper side of the feed rack, and a support frame is provided at the lower end of the storage rack. A piercing component is provided on the inner side of the support frame. A second drive motor is provided on the left side of the feed rack, and a push rod is provided on the right side of the second drive motor. A third drive motor is provided on the left side of the outer shell, and a support rod is provided on the right side of the third drive motor. A stirring rod is provided on the outer side of the support rod, and a heat spreader is provided on the outer side of the stirring rod. An igniter is provided at the lower end of the third drive motor, and a fuel pipe is provided on the left side of the igniter. A flame nozzle is provided on the right side of the igniter. A discharge valve is provided at the lower end of the outer shell, and a discharge chute is provided at the lower end of the discharge valve. A guide block is provided on the right side of the discharge chute. An air inlet pipe is provided at the upper right side of the outer shell. A baffle plate is provided on the right side of the support rod, and a door is provided on the right side of the baffle plate.

[0008] In one possible implementation, the puncture assembly includes a first drive motor mounted in the middle of the support frame, a drive rod disposed on the upper side of the first drive motor, a puncture needle disposed on the upper side of the drive rod, and a guide rod disposed on the outer side of the puncture needle.

[0009] In one possible implementation, the drive rod is threadedly connected to the puncture needle, and the guide rod is symmetrically arranged about the central axis of the puncture needle, and the guide rod is slidably arranged relative to the support frame.

[0010] In one possible implementation, the stirring rod and the support rod are engaged relative to each other, and the stirring rod is positioned at an equal angle to the outside of the support rod.

[0011] In one possible implementation, the heat spreader is engaged with the outer casing, and the heat spreader is symmetrically arranged about the central axis of the outer casing.

[0012] In one possible implementation, the guide block is slidably disposed relative to the outer shell, and the longitudinal section of the guide block has a "T" shaped structure.

[0013] In one possible implementation, a filter plate is provided inside the baffle plate, and a positioning rod is provided outside the filter plate.

[0014] In one possible implementation, the filter plate and the positioning rod are engaged with each other, and the longitudinal section of the filter plate is an arc-shaped structure, and the filter plate is symmetrically arranged about the central axis of the baffle plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This oxidation calcination device for ammonium paratungstate processing facilitates uniform feeding of ammonium paratungstate raw materials during use, greatly improving the feeding and processing efficiency of the device and reducing the labor intensity of operators. It also possesses a certain waste gas filtration function, preventing the waste gas from carrying large amounts of ammonium paratungstate raw material particles outwards, thus reducing the impact of waste gas on the environment outside the device and achieving a better processing effect, as detailed below:

[0016] 1. The first drive motor, in conjunction with the drive rod, pushes the puncture needle to move upward along the guide rod, so that the puncture needle punctures the ammonium paratungstate packaging. At the same time, the second drive motor drives the push rod to rotate inside the feed rack, pushing the ammonium paratungstate to move to the right and fall evenly into the inside of the shell, thereby improving the feeding efficiency of the device and reducing labor costs.

[0017] 2. The third drive motor, in conjunction with the support rod, drives the stirring rod to rotate inside the shell, thereby stirring the ammonium paratungstate raw material retained inside the shell. This prevents uneven heating of the ammonium paratungstate during calcination, which would affect the processing efficiency of the device and improve the processing quality.

[0018] 3. The ammonium paratungstate raw material particles in the exhaust gas are filtered by a filter plate and a baffle plate, so that the exhaust gas does not carry a large number of ammonium paratungstate raw material particles to the outside and is discharged, thus reducing the impact of the exhaust gas on the environment outside the device.

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.

[0026] Please see Figure 1-5 This utility model provides a technical solution: an oxidation calcination device for processing ammonium paratungstate, comprising: a shell 1, and a feeding rack 2 disposed on the upper side of the shell 1, and further comprising:

[0027] A shelf 3 is installed on the upper side of the feed rack 2, and a support frame 4 is provided at the lower end of the shelf 3. A piercing component 5 is provided on the inner side of the support frame 4. A second drive motor 6 is provided on the left side of the feed rack 2, and a push rod 7 is provided on the right side of the second drive motor 6. A third drive motor 8 is provided on the left side of the outer casing 1, and a support rod 9 is provided on the right side of the third drive motor 8. A stirring rod 10 is provided on the outer side of the support rod 9, and a heat spreader 11 is provided on the outer side of the stirring rod 10. The third drive motor 8... An igniter 12 is provided at the lower end of the device, and a fuel pipe 13 is provided on the left side of the igniter 12. A flame nozzle 14 is provided on the right side of the igniter 12. A discharge valve 15 is provided at the lower end of the outer casing 1, and a discharge trough 16 is provided at the lower end of the discharge valve 15. A guide block 17 is provided on the right side of the discharge trough 16. An air inlet pipe 18 is provided at the upper right side of the outer casing 1. A baffle plate 19 is provided on the right side of the support rod 9, and an organic door 22 is provided on the right side of the baffle plate 19, thus forming a complete oxidation calcination device.

[0028] like Figure 1 , Figure 3 and Figure 5As shown, the puncture assembly 5 includes a first drive motor 501 installed in the middle of the support frame 4, and a drive rod 502 is provided on the upper side of the first drive motor 501. A puncture needle 503 is provided on the upper side of the drive rod 502, and a guide rod 504 is provided on the outer side of the puncture needle 503. The drive rod 502 and the puncture needle 503 are threadedly connected, and the guide rod 504 is symmetrically arranged about the central axis of the puncture needle 503. The guide rod 504 is slidably arranged relative to the support frame 4. By placing the well-packaged ammonium paratungstate raw material into the storage container... Inside the frame 3, the first drive motor 501 drives the drive rod 502 to rotate inside the support frame 4, causing the drive rod 502 to push the piercing needle 503 to move upward along the guide rod 504. At this time, the piercing needle 503 pierces the package, causing the ammonium paratungstate to fall downward. At this time, the second drive motor 6 drives the push rod 7 to rotate inside the feed frame 2, causing the push rod 7 to push the ammonium paratungstate to move to the right and fall evenly into the interior of the outer shell 1. This completes the convenient feeding of ammonium paratungstate, improves the feeding efficiency of the device, and reduces labor costs.

[0029] like Figure 1 , Figure 2 and Figure 4 As shown, the stirring rod 10 is engaged with the support rod 9, and the stirring rod 10 is set at an equal angle to the outside of the support rod 9. The heat spreader 11 is engaged with the outer shell 1, and the heat spreader 11 is symmetrically arranged about the central axis of the outer shell 1. The guide block 17 is slidably arranged with the outer shell 1, and the longitudinal section of the guide block 17 is a "T" shaped structure. The support rod 9 is driven to rotate inside the outer shell 1 by the third drive motor 8, so that the support rod 9 drives the stirring rod 10 to stir the ammonium paratungstate raw material retained inside the outer shell 1. This avoids uneven heating of ammonium paratungstate during calcination, which affects the processing efficiency of the device and improves the processing quality.

[0030] like Figure 1 and Figure 2 As shown, a filter plate 20 is provided inside the baffle plate 19, and a positioning rod 21 is provided on the outside of the filter plate 20. The filter plate 20 and the positioning rod 21 are engaged with each other. The longitudinal section of the filter plate 20 is an arc-shaped structure, and the filter plate 20 is symmetrically arranged about the central axis of the baffle plate 19. After the device is used, the exhaust gas is discharged to the right. At this time, the filter plate 20 provided inside the baffle plate 19 filters the residual particles of ammonium paratungstate in the exhaust gas, so that the exhaust gas is less likely to carry a large amount of ammonium paratungstate raw material particles to the outside and discharge them to the outside, thereby reducing the impact of the exhaust gas on the environment outside the device.
