Abstract
Description
Technical Field
[0001] This utility model relates to the field of pharmaceutical preparation technology, specifically to a spiral propulsion device. Background Technology
[0002] In the chemical pesticide manufacturing industry, solid impurities may remain in the pesticide solution during the production process. In order not to affect the efficacy of the pesticide, it is generally necessary to filter out the fixed impurities in the pesticide.
[0003] Most existing pesticide filtration devices directly inject the pesticide solution into the filter chamber and filter it through a filter screen to separate the fixed impurities in the solution. However, when filtering pesticide solution, fixed impurities can easily clog the filter screen, affecting the separation efficiency of pesticide solution and impurities. Furthermore, the filtered solid impurities remain on the filter screen, requiring manual cleaning of the fixed impurities after filtration, which is troublesome, time-consuming, and labor-intensive. Therefore, it is necessary to provide a spiral propulsion device to solve the above problems. Utility Model Content
[0004] To solve the above-mentioned technical problems, a spiral propulsion device is provided. This technical solution addresses the issue that most existing pesticide filtration devices mentioned in the background technology directly inject the pesticide solution into the filter chamber and filter the solution through a filter screen to separate the fixed impurities in the solution. However, when filtering the pesticide solution, the fixed impurities easily clog the filter screen, affecting the separation efficiency of the pesticide solution and impurities. Furthermore, the filtered solid impurities remain on the filter screen, requiring manual cleaning of the fixed impurities after filtration, which is troublesome, time-consuming, and labor-intensive.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A spiral propulsion device includes a first propulsion chamber, a slag discharge pipe fixedly connected to one side of the top of the first propulsion chamber, a second propulsion chamber fixedly connected to the top of the slag discharge pipe, a filter screen provided on one side of both the first and second propulsion chambers, a second gear rotatably connected to the other side of the first propulsion chamber, a first gear rotatably connected to the other side of the second propulsion chamber, a shaft fixedly connected to the middle of one side of both the first and second gears, and a spiral propulsion blade provided on the outer side of the shaft.
[0007] Preferably, a sealing disc is provided on the other side of the inner side of both the first propulsion compartment and the second propulsion compartment. The sealing disc is fixedly connected to the shaft. A portion of the shaft between the sealing disc and the first gear is connected through to the other side of the second propulsion compartment. A portion of the shaft between the sealing disc and the second gear is connected through to the other side of the first propulsion compartment.
[0008] Preferably, a liquid inlet is fixedly connected to the other side of the top of the second propulsion chamber, and a positioning plate is fixedly connected to the bottom end of one side of the liquid inlet. A motor is provided in the middle of one side of the first gear, and the bottom end of the positioning plate is engaged with the motor.
[0009] Preferably, the first gear is meshed with the second gear, and a slag discharge port is fixedly connected to one side of the bottom of the first propulsion chamber.
[0010] Preferably, multiple sets of mounting support plates are symmetrically distributed at the bottom of the first propulsion compartment, and the top of the mounting support plates is fixedly connected to the first propulsion compartment.
[0011] Preferably, a positioning ring is snapped onto the outer side of the filter screen, and the positioning ring is detachably connected to the corresponding first propulsion chamber and second propulsion chamber.
[0012] Preferably, a spiral positioning ring plate is fixedly connected to the spiral propeller blade near the shaft. The spiral positioning ring plate is provided with multiple fixing nuts, and the spiral propeller blade is installed and fixed to the shaft through the fixing nuts and the spiral positioning ring plate.
[0013] Preferably, the surface of the spiral propulsion blade is provided with multiple sets of filter holes, and a set of fixing plates is fixedly connected to the other side of the top of the first propulsion compartment.
[0014] Compared with the prior art, the present invention provides a spiral propulsion device with the following advantages: it facilitates the rapid separation of larger impurities in the liquid medicine during the filtration process, prevents the filter screen from becoming clogged, improves the efficiency of liquid medicine production, and facilitates the disassembly and replacement of the spiral propulsion blades, thereby reducing resource waste.
[0015] The chemical solution is filtered through a second propulsion chamber, spiral propulsion blades, a shaft, a slag discharge pipe, a first propulsion chamber, and a slag discharge port. During filtration, the solution flows through the filter holes on the spiral propulsion blades inside the second propulsion chamber, while solid impurities remain in the spiral pushing cavity formed by the spiral propulsion blades and the inner wall of the second propulsion chamber. The shaft rotating inside the second propulsion chamber drives the corresponding spiral propulsion blades to rotate. These rotating blades push the solid impurities in the spiral cavity slowly towards one side of the second propulsion chamber. When the solution reaches the slag discharge pipe, it falls into the first propulsion chamber and is then filtered through the first propulsion chamber. The filter screen located on the side flows out and falls into a liquid storage container located at the bottom of the first propulsion chamber. When solid impurities are pushed by the spiral propulsion blades located inside the second propulsion chamber to the position of the slag discharge pipe, they will pass through the slag discharge pipe and fall into the first propulsion chamber. The rotating shaft inside the first propulsion chamber drives the corresponding spiral propulsion blades to rotate in the opposite direction, moving the solid impurities towards the slag discharge port fixedly connected to the bottom of the first propulsion chamber. When the solid impurities reach the slag discharge port, they pass through the slag discharge port and fall into the slag collection container located below. This facilitates the rapid separation of larger impurities in the liquid during the filtration process, prevents the filter screen from becoming clogged, and helps improve the production efficiency of the liquid.
[0016] When replacing the propeller blade using the fixed nut, shaft, and spiral positioning ring plate, the fixed nut is rotated to remove it from the spiral positioning ring plate. Then, the propeller blade is slid to one side, and it will slide along the shaft to separate from it. At this point, the new propeller blade can be slid and locked onto the shaft. The fixed nut is then locked onto the spiral positioning ring plate fixed to the propeller blade, and then through the spiral positioning ring plate and locked onto the shaft. This allows the new propeller blade to be installed and fixed onto the shaft, facilitating the disassembly and replacement of the propeller blade and reducing resource waste.

[0023] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.
[0024] Example 1
[0025] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a spiral propulsion device includes a first propulsion chamber 1. A slag discharge pipe 3 is fixedly connected to one side of the top of the first propulsion chamber 1. A second propulsion chamber 4 is fixedly connected to the top of the slag discharge pipe 3. A filter screen 13 is provided on one side of both the first propulsion chamber 1 and the second propulsion chamber 4. A second gear 9 is rotatably connected to the other side of the first propulsion chamber 1. A first gear 8 is rotatably connected to the other side of the second propulsion chamber 4. A shaft 15 is fixedly connected to the middle of one side of both the first gear 8 and the second gear 9. A spiral propulsion blade 16 is provided on the outer side of the shaft 15. A sealing disc 14 is provided on the other side of the inner side of both the first propulsion chamber 1 and the second propulsion chamber 4. The sealing disc 14 is fixedly connected to the shaft 15. The portion of the shaft 15 between the sealing disc 14 and the first gear 8 is connected to the first gear 9. The other side of the second propulsion chamber 4 is connected through, and the part of the shaft 15 between the sealing disc 14 and the second gear 9 is connected through to the other side of the first propulsion chamber 1. The other side of the top of the second propulsion chamber 4 is fixedly connected to the liquid inlet 5. The bottom of one side of the liquid inlet 5 is fixedly connected to the positioning hanging plate 6. The middle of one side of the first gear 8 is provided with a motor 7. The bottom of the positioning hanging plate 6 is engaged with the motor 7. The first gear 8 and the second gear 9 are meshed. The bottom of the first propulsion chamber 1 is fixedly connected to the slag discharge port 10. The bottom of the first propulsion chamber 1 is symmetrically distributed with multiple sets of mounting support plates 2. The top of the mounting support plates 2 is fixedly connected to the first propulsion chamber 1. The surface of the spiral propulsion blade 16 is provided with multiple sets of filter holes. The other side of the top of the first propulsion chamber 1 is fixedly connected to a set of fixing plates 11.
[0026] In this embodiment, when the liquid medicine is filtered, it is injected into the second propulsion chamber 4 through the inlet 5. The liquid medicine flows to one side of the second propulsion chamber 4 through the filter holes on the spiral propulsion blade 16 provided on the inner side of the second propulsion chamber 4. Solid impurities in the liquid medicine are retained in the spiral pushing cavity formed by the spiral propulsion blade 16 and the inner wall of the second propulsion chamber 4. The motor 7 drives the first gear 8, which is fixedly connected to the output end, to rotate. The rotating first gear 8 drives the second gear 9, which is meshed at the bottom, to rotate in the opposite direction. This causes a shaft 15, which is fixedly connected to the middle of one side of the first gear 8 and the second gear 9, to rotate relative to each other. The rotating shaft 15 inside the second propulsion chamber 4 drives the corresponding spiral propulsion blade 16 on the outside to rotate. The rotating spiral propulsion blade 16 pushes the solid impurities retained in the spiral cavity to slowly move to one side of the second propulsion chamber 4. When the liquid medicine flows to the position of the slag discharge pipe 3, part of the liquid medicine will pass through the second propulsion chamber 4... The liquid flows out through the side-mounted filter screen 13 and falls into the liquid storage container below. The remaining liquid will fall into the first propulsion chamber 1 through the slag discharge pipe 3 and into the liquid storage container at the bottom of the first propulsion chamber 1. When solid impurities are pushed by the spiral propulsion blade 16 inside the second propulsion chamber 4 to the position of the slag discharge pipe 3, they will pass through the slag discharge pipe 3 and fall into the first propulsion chamber 1. The rotating shaft 15 inside the first propulsion chamber 1 drives the corresponding spiral propulsion blade 16 to rotate in the opposite direction, moving the solid impurities to the position of the slag discharge port 10 fixedly connected to the bottom of the first propulsion chamber 1. When the solid impurities move to the position of the slag discharge port 10, they pass through the slag discharge port 10 and fall into the slag collection container below. When the shaft 15 rotates, the sealing plate 14 blocks the liquid to prevent the liquid from flowing out through the gap between the shaft 15 and the second propulsion chamber 4.
[0027] Example 2
[0028] Please refer to Figure 2 , Figure 3 and Figure 4 As shown; a positioning ring 12 is snapped onto the outer side of the filter screen 13. The positioning ring 12 is detachably connected to the corresponding first propulsion chamber 1 and second propulsion chamber 4. A spiral positioning ring plate 17 is fixedly connected to the spiral propulsion blade 16 near the shaft 15. The spiral positioning ring plate 17 is provided with multiple fixing nuts 18. The spiral propulsion blade 16 is installed and fixed to the shaft 15 through the fixing nuts 18 and the spiral positioning ring plate 17.
[0029] In this embodiment, when replacing the filter screen 13, multiple fixing nuts provided on one side of the rotating positioning ring 12 are used to remove the fixing nuts from the positioning ring 12. Then, the positioning ring 12 is removed from the correspondingly connected first propulsion chamber 1 and second propulsion chamber 4. The new filter screen 13 is then reinstalled and fixed onto the first propulsion chamber 1 and the second propulsion chamber 4. When replacing the spiral propulsion blade 16, the fixing nut 18 is rotated to remove the fixing nut 18 from the spiral positioning ring plate 17. Then, the spiral propulsion blade 16 is slid to one side and separated from the shaft 15. At this time, the spiral propulsion blade 16 to be replaced can be slid and locked onto the shaft 15. The fixing nut 18 is locked onto the spiral positioning ring plate 17 fixed on the spiral propulsion blade 16 and then through the spiral positioning ring plate 17 and locked onto the shaft 15, thereby installing and fixing the new spiral propulsion blade 16 onto the shaft 15.
[0030] The working principle and usage of this device are as follows: When filtering the liquid medicine, the liquid medicine is injected into the second propulsion chamber 4 through the inlet 5. The liquid medicine flows to one side of the second propulsion chamber 4 through the filter holes on the spiral propulsion blade 16 provided on the inner side of the second propulsion chamber 4. Solid impurities in the liquid medicine will be retained in the spiral pushing cavity formed by the spiral propulsion blade 16 and the inner wall of the second propulsion chamber 4. The motor 7 drives the first gear 8, which is fixedly connected to the output end, to rotate. The rotating first gear 8 drives the second gear 9, which is meshed at the bottom, to rotate in the opposite direction. This causes a shaft 15, which is fixedly connected to the middle of one side of the first gear 8 and the second gear 9, to rotate relative to each other. The rotating shaft 15 on the inner side of the second propulsion chamber 4 drives the corresponding spiral propulsion blade 16 on the outer side to rotate. The rotating spiral propulsion blade 16 pushes the solid impurities retained in the spiral cavity to one side of the interior of the second propulsion chamber 4. When the liquid medicine... When the liquid flows to the slag discharge pipe 3, some of the liquid will flow out through the filter screen 13 on one side of the second propulsion chamber 4 and fall into the liquid storage container below. The remaining liquid will fall into the first propulsion chamber 1 through the slag discharge pipe 3 and flow out through the filter screen 13 on one side of the first propulsion chamber 1 and fall into the liquid storage container on the bottom side of the first propulsion chamber 1. When solid impurities move to the position of the slag discharge pipe 3 under the push of the spiral propulsion blade 16 on the inside of the second propulsion chamber 4, they will pass through the slag discharge pipe 3 and fall into the first propulsion chamber 1. The rotating shaft 15 on the inside of the first propulsion chamber 1 drives the corresponding spiral propulsion blade 16 to rotate in the opposite direction, moving the solid impurities to the position of the slag discharge port 10 fixedly connected to the bottom side of the first propulsion chamber 1. When the solid impurities move to the position of the slag discharge port 10, they pass through the slag discharge port 10 and fall into the slag collection container below.
