Abstract
Description
Technical Field
[0001] This utility model relates to the field of drug dosing technology, specifically to a drug dosing device. Background Technology
[0002] Currently, chemicals are injected during wastewater treatment to ensure thorough mixing and improve water quality. However, existing technologies often fail to weigh the chemicals during dosing, leading to waste when too much is added and poor treatment results in inadequate dosing. Furthermore, the chemicals flow vertically into a fixed position within the treatment tank, reducing the mixing effect. Therefore, we propose a chemical dosing device. Utility Model Content
[0003] The technical problem this invention aims to solve is to overcome existing defects and provide a reagent dosing device. In use, the reagent is added to the feeding tank through the feeding port for weighing, improving the mixing ratio and wastewater treatment effect, avoiding waste caused by excessive reagent injection, and achieving good results. After weighing, the drive assembly is activated, driving the second rotating shaft to rotate. The second rotating shaft rotates the second gear, which in turn rotates the first gear, which in turn rotates the first rotating shaft, which in turn rotates the feeding tank. The rotating feeding tank pours the reagent into the installation bucket connected to the mounting cover, completing the reagent dosing. Simultaneously, the rotation of the second rotating shaft drives the half-gear to rotate. The half-gear, in conjunction with the two racks and the action of the sliding plate and chute, completes the reciprocating cycle of the rectangular frame. The left-right reciprocating motion of the rectangular frame drives the connecting bracket and the V-shaped plate to reciprocate left and right. Thus, the reagent falling onto the V-shaped plate, under the action of the V-shaped plate's left-right reciprocating motion and the action of the dispensing hole, evenly falls into the installation bucket, further improving the wastewater treatment effect and effectively solving the problems in the background technology.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a drug dosing device, comprising a mounting cover, a cross-shaped frame, a rectangular frame, and a drive assembly;
[0005] A cross-shaped bracket is rotatably connected to the lower surface of the mounting cover. A first rotating shaft is rotatably mounted on the middle left side of the cross-shaped bracket, and a feeding box is mounted on the first rotating shaft. A weighing scale is installed inside the feeding box. A feeding port is opened on the mounting cover, and the feeding port corresponds vertically to the middle of the feeding box. A first gear is mounted on the first rotating shaft. A second rotating shaft is rotatably mounted on the lower left side of the cross-shaped bracket, and a second gear is mounted on the second rotating shaft. The first gear and the second gear are meshed together. A cylinder is mounted in the middle of the second rotating shaft, and multiple tooth blocks are evenly mounted on one half of the outer surface of the cylinder. A semi-gear is formed. Racks are installed on both the upper and lower sides of the interior of the rectangular frame. The semi-gear is located between the two racks and meshes with them. A sliding plate is installed on the lower surface of the rectangular frame. A groove is opened on the lower upper surface of the cross flower frame corresponding to the sliding plate. The sliding plate is slidably installed on the groove. A connecting bracket is installed on the upper surface of the rectangular frame. A V-shaped plate is installed at the upper end of the connecting bracket. The V-shaped plate is high in the middle and low at both ends. Multiple medicine holes are evenly opened at both ends of the V-shaped plate. A driving component is provided on the right side of the cross flower frame. The driving component is connected to the second rotating shaft.
[0006] Furthermore, the lower surface of the mounting cover has an annular groove, and the inner wall of the annular groove has an annular limiting groove. An annular limiting plate is rotatably installed in the annular limiting groove. The upper end of the cross-shaped bracket is connected to the annular limiting plate. The top wall of the annular groove has two arc-shaped through slots, and a handle is slidably installed in the arc-shaped through slots. The lower end of the handle is connected to the annular limiting plate. By moving the handle, the annular limiting plate moves within the annular limiting groove, thereby using the movement of the annular limiting plate to drive the rotation of the cross-shaped bracket, further improving the uniformity of pesticide application.
[0007] Furthermore, the drive assembly includes a motor slot located on the right side of the cross-shaped frame, in which a motor is housed. The output shaft of the motor is connected to the right end of the second rotating shaft via a coupling, and the input end of the motor is electrically connected to the output end of an external controller. The external controller controls the motor's operation, which in turn drives the second rotating shaft to rotate, thus electrically completing the rotation of the second rotating shaft.
[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the agent is added to the feeding box through the feeding port for weighing, thereby improving the mixing ratio and wastewater treatment effect, avoiding waste caused by excessive agent injection, and achieving good results. After weighing, the drive component is activated, driving the second rotating shaft to rotate, which in turn drives the second gear to rotate, which in turn drives the first gear to rotate, which in turn drives the first rotating shaft to rotate, which in turn drives the feeding box to rotate. The rotating feeding box pours the agent into the installation bucket connected to the installation cover, completing the agent addition. Simultaneously, the rotation of the second rotating shaft drives the half gear to rotate. The half gear, in conjunction with the two racks and the action of the sliding plate and chute, completes the reciprocating cycle of the rectangular frame. The reciprocating motion of the rectangular frame drives the connecting bracket and the V-shaped plate to reciprocate left and right. Thus, the agent falling onto the V-shaped plate, under the action of the reciprocating motion of the V-shaped plate and the action of the dispensing hole, is evenly distributed into the installation bucket, further improving the wastewater treatment effect.

[0014] A cross-shaped bracket 8 is rotatably connected to the lower surface of the mounting cover 1. A first rotating shaft 3 is rotatably mounted on the middle left side of the cross-shaped bracket 8. A feeding box 6 is mounted on the first rotating shaft 3, and a weighing scale 17 is installed inside the feeding box 6. A feeding port 5 is opened on the mounting cover 1, and the feeding port 5 corresponds vertically to the middle of the feeding box 6. A first gear 7 is mounted on the first rotating shaft 3. A second rotating shaft 13 is rotatably mounted on the lower left side of the cross-shaped bracket 8. A second gear 15 is mounted on the second rotating shaft 13. The first gear 7 and the second gear 15 are meshed together. A cylinder 11 is mounted in the middle of the second rotating shaft 13, and multiple tooth blocks 1 are evenly mounted on one half of the outer surface of the cylinder 11. A half-gear is formed. Racks 9 are installed on both the upper and lower sides of the interior of the rectangular frame 12. The half-gear is located between the two racks 9 and meshes with the racks 9. A slide plate 20 is installed on the lower surface of the rectangular frame 12. A groove 21 is opened on the lower upper surface of the cross frame 8 corresponding to the slide plate 20. The slide plate 20 is slidably installed on the groove 21. A connecting bracket is installed on the upper surface of the rectangular frame 12. A V-shaped plate 14 is installed at the upper end of the connecting bracket. The V-shaped plate 14 is high in the middle and low at both ends. Multiple medicine holes 18 are evenly opened at both ends of the V-shaped plate 14. A drive assembly is provided on the right side of the cross frame 8. The drive assembly is connected to the second rotating shaft 13.
[0015] During use, the agent is added to the feeding box 6 through the feeding port 5 for weighing to improve the mixing ratio and wastewater treatment effect, avoiding waste caused by excessive agent injection. After weighing, the drive assembly is activated, driving the second rotating shaft 13 to rotate. The rotation of the second rotating shaft 13 drives the second gear 15 to rotate, which in turn drives the first gear 7 to rotate. The rotation of the first gear 7 drives the first rotating shaft 3 to rotate, which in turn drives the feeding box 6 to rotate, pouring the agent into the... Inside the installation tank connected to the installation cover 1, the agent addition is completed. At the same time, the rotation of the second rotating shaft 13 drives the half gear to rotate. The rotation of the half gear, in conjunction with the meshing of the two racks 9 and the action of the sliding plate 20 and the chute 21, completes the reciprocating cycle of the rectangular frame 12. The left and right reciprocating motion of the rectangular frame 12 drives the connecting bracket and the V-shaped plate 14 to reciprocate left and right. Thus, the agent falling on the V-shaped plate 14 is evenly distributed into the installation tank under the action of the left and right reciprocating motion of the V-shaped plate 14 and the action of the dispensing hole 18, so as to further improve the sewage treatment effect.
[0016] The lower surface of the mounting cover 1 has an annular groove 4, and the inner wall of the annular groove 4 has an annular limiting groove. An annular limiting plate 19 is rotatably installed in the annular limiting groove. The upper end of the cross bracket 8 is connected to the annular limiting plate 19. The top wall of the annular groove 4 has two arc-shaped through grooves 22, and a handle 2 is slidably installed in the arc-shaped through grooves 22. The lower end of the handle 2 is connected to the annular limiting plate 19. By moving the handle 2, the annular limiting plate 19 is moved within the annular limiting groove, thereby using the movement of the annular limiting plate 19 to drive the rotation of the cross bracket 8, thus further improving the uniformity of the agent addition.
[0017] The drive assembly includes a motor slot located on the right side of the cross-shaped frame 8, in which a motor 16 is housed. The output shaft of the motor 16 is connected to the right end of the second rotating shaft 13 via a coupling. The input end of the motor 16 is electrically connected to the output end of an external controller. The external controller controls the operation of the motor 16, which in turn drives the second rotating shaft 13 to rotate, thus electrically completing the rotation of the second rotating shaft 13.
[0018] The working principle of the reagent dosing device provided by this utility model is as follows: During use, the reagent is added into the feeding box 6 through the feeding port 5 for weighing to improve the mixing ratio and wastewater treatment effect, avoiding waste caused by excessive reagent injection, resulting in good usage. After weighing is completed, the drive component is activated, driving the second rotating shaft 13 to rotate. The rotation of the second rotating shaft 13 drives the second gear 15 to rotate, which in turn drives the first gear 7 to rotate. The rotation of the first gear 7 drives the first rotating shaft 3 to rotate, which in turn drives the feeding box 6 to rotate. The feeding box 6 rotates to pour the agent into the installation bucket connected to the installation cover 1, completing the agent addition. Simultaneously, the second rotating shaft 13 rotates, driving the half-gear to rotate. The half-gear, meshing with the two racks 9 and acting on the slide plate 20 and slide groove 21, completes the reciprocating cycle of the rectangular frame 12. The left-right reciprocating motion of the rectangular frame 12 drives the connecting bracket and the V-shaped plate 14 to reciprocate left-right. Thus, the agent falling on the V-shaped plate 14, under the action of the V-shaped plate 14's left-right reciprocating motion and the action of the dispensing hole 18, evenly falls into the installation bucket, further improving the wastewater treatment effect. Moving the handle 2 drives the annular limiting plate 19 to move within the annular limiting groove, thereby using the movement of the annular limiting plate 19 to drive the cross-shaped frame 8 to rotate, further improving the uniformity of agent addition. An external controller controls the motor 16 to operate, driving the second rotating shaft 13 to rotate, thus electrically completing the rotation of the second rotating shaft 13.
[0019] It is worth noting that in this embodiment, the core chip of the external controller is an STC microcontroller, specifically the STC15W204S, while the motor 16 can be freely configured according to the actual application scenario. The external controller controls the operation of the motor 16 using methods commonly used in the prior art, and the content not described in detail in this specification belongs to the prior art known to those skilled in the art.
