[0032] The reaction furnace 4 discharging screw device provided by the embodiment is used to ensure that hydrogen fluoride gas in the reaction furnace 4 does not leak when discharging materials.
[0033] As shown in Figure 1 , Figure 2 , it is a specific embodiment of the reaction furnace 4 discharging screw device provided by the embodiment, the pipeline piece 1, the driving device and the rotating shaft 5, the rotating shaft 5 is provided with the first spiral blade 6. The first spiral blade 6 is used to convey the material. The pipeline piece 1 has a feeding port 2 and a discharging port 3, and the feeding port 2 of the pipeline piece 1 extends into the reaction furnace 4. The reaction furnace 4 is a rotary furnace, and the reaction furnace 4 can rotate, so that the material mixing reacts. The sealing device is arranged between the reaction furnace 4 and the pipeline piece 1, which is used to prevent gas leakage. The connection structure between the reaction furnace 4 and the pipeline is prior art, and the embodiment will not be described again. The driving end of the driving device is connected with the rotating shaft 5, the rotating shaft 5 is rotatably arranged in the pipeline piece 1, and the rotating shaft 5 is concentrically arranged with the pipeline piece 1. The first spiral blade 6 is arranged on the rotating shaft 5 in the axial direction and is arranged at intervals between the multiple first spiral blades 6. The first spiral blade 6 close to the feeding port 2 is arranged below the feeding port 2, and the first spiral blade 6 close to the discharging port 3 is arranged at intervals with the discharging port 3 in the horizontal direction.
[0034] When the material continuously enters the pipeline from the feeding port 2, the first spiral blade 6 pushes the material to move towards the discharging port 3. When no material continuously enters the pipeline piece 1, the multiple first spiral blades 6 are arranged at intervals, that is, after the material enters the pipeline piece 1, the first group of first spiral blades 6 pushes the material towards the second group of first spiral blades 6, and the material will first accumulate between the first group of spiral blades and the second group of spiral blades, and when the material is accumulated between the first group of first spiral blades 6 and the second group of first spiral blades 6, the material will continue to be pushed towards the discharging port 3 under the subsequent material. By analogy, the material will be accumulated between the multiple first spiral blades 6, so as to multiple seal the inside of the pipeline piece 1, so as to prevent the hydrogen fluoride gas from leaking from the discharging port 3 of the pipeline.
[0035] By setting multiple sets of first spiral blades 6 with intervals between them, the material accumulates at the intervals between adjacent first spiral blades 6, thereby ensuring the sealing of the inside of the pipe component 1.
[0036] like Figure 2 As shown, in this embodiment, two sets of first spiral blades 6 are provided. The first set of first spiral blades 6 is located below the feed inlet 2 to push the material towards the discharge outlet 3, while preventing material accumulation at the feed inlet 2. The second set of first spiral blades 6 is located between the first set of first spiral blades 6 and the discharge outlet 3, spaced apart from both. This allows material to accumulate in the gaps between the first and second sets of first spiral blades 6, and also between the second set of first spiral blades 6 and the discharge outlet 3, thus increasing the number of protection layers and ensuring that hydrogen fluoride gas does not leak. Alternatively, as an alternative implementation, the number of first spiral blades 6 is not limited; it can also be three sets, four sets, etc.
[0037] like Figure 2 As shown, in this embodiment, the rotating shaft 5 has a second spiral blade 7 on the side of the discharge port 3 facing away from the inlet 2. The rotation direction of the second spiral blade 7 is opposite to that of the first spiral blade 6. Since the discharge port 3 is not located at the end of the pipe fitting, but rather in the middle of the pipe fitting facing away from the inlet 2, there is still material between the discharge port 3 and the end of the pipe fitting. The second spiral blade 7 can reverse the spiral direction of the material between the discharge port 3 and the pipe fitting back to the discharge port 3, thereby achieving complete discharge of the material and avoiding material residue inside the pipe fitting. This improves the material processing efficiency and reduces the cleaning workload caused by residual material. Alternatively, as an alternative implementation, the second spiral blade 7 can be omitted, and the discharge port 3 can be located at the axial end of the pipe fitting.
[0038] like Figure 2 As shown, in this embodiment, the discharge port 3 is located at the upper end of the pipe component 1, ensuring that the material fills the pipe component 1 under the conveying of the first spiral blade 6. When no material is being conveyed, the rotation of the shaft 5 also ensures that material accumulates between two adjacent first spiral blades 6, and the material will not be moved due to the rotation of the shaft 5. At this time, the material will block the pipe component 1. When the material continues to move towards the discharge port 3, the material will first accumulate below the discharge port 3, and then slowly overflow from the discharge port 3 under the rotation of the shaft 5. When no more material enters the pipe component 1, the material will not overflow from the discharge port 3 because there is no new material replenishment. In addition, as an alternative implementation, the discharge port 3 can also be located at the lower end of the pipe component 1, which can also achieve material conveying.
[0039] like Figure 1As shown, in this embodiment, the feeding port 2 of the pipeline piece 1 is provided with a feeding hopper 8, the lower end of the feeding hopper 8 is communicated with the feeding port 2, the feeding hopper 8 can concentrate and guide the material into the feeding port 2 of the pipeline piece 1, ensure that the material enters in order and stably, avoid the material scattering or accumulating outside the pipeline, and improve the efficiency of material conveying. At the same time, the design of the feeding hopper 8 can usually prevent the material from splashing or leaking during conveying, further reducing waste. In addition, as an alternative embodiment, the feeding hopper 8 can also not be provided, and the feeding can also be realized.
[0040] As shown in the figure, Figure 1 As shown in the figure, in this embodiment, the cross section of the feeding hopper 8 is circular, and the diameter of the feeding hopper 8 gradually increases when extending upward from the feeding port 2. The gradually increasing diameter of the feeding hopper 8 can make more material enter the feeding port 2; at the same time, the material flows more smoothly in the feeding hopper 8 towards the feeding port 2, reducing the possibility of clogging and accumulation, thereby improving production efficiency. In addition, as an alternative embodiment, the cross section of the feeding hopper 8 can also be rectangular. In addition, as an alternative embodiment, the cross section of the feeding hopper 8 can also be circular at the top and circular at the bottom.
[0041] As shown in the figure, Figure 2 As shown in the figure, in this embodiment, a plurality of fixed parts 9 are provided on the rotating shaft 5 radially outward between the first spiral blade 6 and the discharge port 3, and the fixed parts 9 are cylindrical. The fixed parts 9 are used to break up the material accumulated between the first spiral blade 6 and the discharge port 3, preventing it from caking. In addition, as an alternative embodiment, the fixed parts 9 can also be provided in other shapes, for example: square.
[0042] As shown in the figure, Figure 2 As shown in the figure, in this embodiment, a plurality of fixed parts 9 are provided along the axial direction of the rotating shaft 5, and the fixed parts 9 are arranged in multiple. After the fixed parts 9 are arranged in multiple, the accumulated material can be uniformly broken up. In addition, the spacing distance of the fixed parts 9 can be adjusted according to actual needs to achieve the best breaking effect. In addition, as an alternative embodiment, a plurality of fixed parts 9 can also be arranged in multiple in the circumferential direction.
[0043] As shown in the figure, Figure 1 As shown in the figure, in this embodiment, the driving device includes a driving part 10, and the driving part 10 is a motor. The motor as the driving part 10 can provide stable and continuous power output, ensuring that the driving device can operate stably for a long time. The driving part 10 is arranged at one end of the pipeline piece 1 axially away from the reaction furnace 4, which helps to reduce the influence of the reaction furnace 4 on the driving device and improve the safety and stability of the driving device. In addition, as an alternative embodiment, a controller can also be included, and the controller is connected with the driving part 10, so as to control the rotating speed of the driving part 10 and the start and stop of the driving part 10.
[0044] As Figure 1 , Figure 2 In this embodiment, the pipe piece 1 is provided with a rotating seat 11 at both axial ends. The rotating seat 11 is a bearing seat, which is respectively arranged at both axial ends of the pipe piece 1, and the rotating shaft 5 is rotatably connected with the bearing seat. The rotating seat 11 can make the rotating shaft 5 rotate flexibly, thereby ensuring smooth operation of the whole device. In addition, the bearing seat design of the rotating seat 11 can effectively reduce friction and prolong the service life of the device. Inside the rotating seat 11, a bearing is usually installed. The type and specification of the bearing are selected according to the actual working conditions and the diameter of the rotating shaft 5 to ensure the stability and reliability of the device under different working conditions. In addition, as an alternative embodiment, a hole can also be directly opened at both axial ends of the pipe piece 1, and then a bearing is installed in the hole.
[0045] The installation mode of the discharge screw device of the reaction furnace 4: the reaction furnace 4 is a rotary furnace. One end of the pipe piece 1 extends into the reaction furnace 4, and the pipe piece 1 is provided with a feeding port 2 at the upper end of the reaction furnace 4. A feeding hopper 8 is arranged at the feeding port 2. A sealing device is arranged between the pipe piece 1 and the reaction furnace 4, which is a prior art. The pipe piece 1 is provided with a discharge port 3 outside the reaction furnace 4, which is arranged at the upper end of the pipe piece 1. A rotating shaft 5 is rotatably arranged in the pipe piece 1, which is driven to rotate by a driving member 10. A first group of first screw blades 6 is arranged below the feeding port 2 on the rotating shaft 5. A second group of first screw blades 6 is arranged between the first group of first screw blades 6 and the discharge port 3, and the second group of first screw blades 6 is arranged at intervals with the first group of screw blades and the discharge port 3. A second screw blade 7 is arranged from the discharge port 3 to the end of the pipe piece 1 away from the feeding port 2, and the rotating direction of the second screw blade 7 is opposite to that of the first screw blade 6.
[0046] Working principle of the discharge screw device of the reaction furnace 4:
[0047] When the material continuously enters, the material first enters the first group of first screw blades 6 from the feeding hopper 8, and the first group of first screw blades 6 is driven by the rotating shaft 5 to push the material to move to the second group of first screw blades 6. Since the first group of first screw blades 6 and the second group of first screw blades 6 are arranged at intervals, the material will accumulate in the interval. After continuously accumulating, the material will move to the second group of first screw blades 6, which will push the material to the discharge port 3. Since the second group of first screw blades 6 and the discharge port 3 are also arranged at intervals, the material will also continuously accumulate here. After accumulating, the material will overflow from the discharge port 3.
[0048] When the material is insufficient, the material cannot enter from the feeding port 2, at this time the rotating shaft 5 rotates, the material is pushed to the interval between the first group of first spiral blades 6 and the second group of first spiral blades 6 by the first group of first spiral blades 6, and the material forms a seal to the pipe piece 1. A spacing is also arranged between the second spiral blade 7 and the discharging port 3, and the material is also accumulated here, and the material also forms a seal to the pipe piece 1.
[0049] Obviously, the above embodiments are only examples for clearly illustrating, but not limitation to the embodiments. Other different forms of changes or variations can be made on the basis of the above description for those skilled in the art. Here, all the embodiments need not and cannot be exhausted. The obvious changes or variations derived therefrom are still within the protection scope of the utility model.
