Description

Technical Field

[0001] The utility model relates to the field of sewage treatment equipment, in particular to a medicine stirring device used for urban sewage treatment. Background Art

[0002] The drug stirring device is an important component of the urban sewage treatment system. It is mainly used to dissolve and disperse the chemicals (such as coagulants, flocculants, fungicides, etc.) into the sewage evenly and quickly to promote the removal or transformation of suspended solids, colloids, soluble organic matter and other substances in the sewage.

[0003] In the process of urban sewage treatment, the ratio of drugs to sewage should be appropriate, and all drugs should be poured into the mixing barrel, and then stirred and mixed by the stirring device. This will cause the drugs (powdered drugs) to clump during the stirring process and cannot be completely mixed with the sewage. In the existing sewage treatment process, most of the powdered drugs are continuously added to the sewage in small doses by shaking with a scoop. A thin layer of powder is spread on the water surface, and the sewage is stirred by a mixer to ensure that the sewage and drugs are fully mixed. The above-mentioned manual auxiliary feeding and stirring method increases the labor intensity of the staff. At the same time, when the workers shake and scatter the drugs, the shaking amplitude is too large, which can easily cause the amount of drugs to be added to be too much, which leads to the problem of insufficient mixing of the drugs.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

A second bevel gear 9 is installed at one end of the shaft rod 7 close to the first bevel gear 8. The first bevel gear 8 is meshed with the second bevel gear 9. A discharge roller 11 is provided in the middle of the shaft rod 7. The discharge roller 11 is located inside the lower end of the hopper 6, and a plurality of equidistantly distributed material troughs 12 are provided on the outer wall of the discharge roller 11; the two ends of the shaft rod 7 are rotatably connected to the two ends of the second mounting frame 5 through bearings; the inner wall of the lower end of the hopper 6 is matched with the outer contour of the discharge roller 11.

[0019] In this embodiment: the motor 4 drives the shaft 7 to rotate synchronously through the stirring rod 3, and uses the shaft 7 to drive the feeding roller 11 in the hopper 6 to rotate, and the medicine in the hopper 6 is quantitatively and continuously fed through the feeding trough 12 on the feeding roller 11, and the dosage is continuous and uniform, thereby reducing the labor intensity of the workers and effectively avoiding the phenomenon of drug agglomeration caused by excessive feeding. In addition, after the stirring rod 3 stops stirring, the shaft 7 also stops rotating, and the medicine in the hopper 6 will also stop being fed, which improves the coordination of drug feeding and stirring.

[0020] Specifically, the present invention installs a first bevel gear 8 at the top of the stirring rod 3, installs an axle rod 7 on one side of the stirring rod 3, and installs a second bevel gear 9 at one end of the axle rod 7 close to the first bevel gear 8; when the drug needs to be stirred, the stirring rod 3 is first driven to rotate by the motor 4, the rotating stirring rod 3 will drive the first bevel gear 8 to rotate, the second bevel gear 9 meshing with the first bevel gear 8 will drive the axle rod 7 to rotate, the rotation of the axle rod 7 will drive the unloading roller 11 to rotate in the hopper 6, the powdered drug in the hopper 6 will fill the material trough 12 on the unloading roller 11, and then the drug in the material trough 12 is quantitatively transported out by the rotation of the unloading roller 11, thereby realizing continuous quantitative drug delivery and making the drug stirring and mixing more sufficient.

[0021] The rotation speed of the stirring rod 3 in this solution also affects the rotation of the feeding roller 11, that is, when stirring quickly, the feeding roller 11 can cooperate with the fast feeding; conversely, when stirring slowly, the feeding roller 11 can cooperate with the slow feeding, which improves the coordination of feeding and stirring. When the stirring rod 3 stops stirring, the shaft 7 also stops rotating, and the medicine in the hopper 6 will also stop feeding (for drugs that are not easy to dissolve, the stirring rod 3 can be allowed to continue rotating after the feeding is completed, and the mixing time can be extended to accelerate the dissolution. In this process, the material in the hopper 6 is empty, and the shaft 7 and the feeding roller 11 can be idle). The operation is simple, practical, and suitable for wide promotion.

[0022] Please refer to Figure 1 to Figure 4 A medicine spreading piece 10 is integrally formed at the discharge port end of the hopper 6. The medicine spreading piece 10 is a flat structure with a hollow interior and an isosceles trapezoidal shape. The lower part of the inner cavity of the medicine spreading piece 10 gradually tightens to form a slit shape; a plurality of guide plates 13 are provided in the inner cavity of the hopper 6, and the plurality of guide plates 13 are equidistantly distributed in the inner cavity of the hopper 6.

[0023] In this embodiment: a medicine-sprinkling piece 10 is provided at the discharge port end of the hopper 6, and the medicine-sprinkling piece 10 is gradually flattened from top to bottom, that is, the discharge port end of the medicine-sprinkling piece 10 is slender and flat. After the medicine powder goes out from the discharge port end of the medicine-sprinkling piece 10, it is similar to a layer of gauze spread on the water surface and then slowly sinks. This medicine-dosing structure can effectively ensure the uniformity of medicine-dosing and make the medicine stirring and mixing more fully. In addition, in this scheme, a plurality of guide plates 13 are provided in the inner cavity of the hopper 6, and the guide plates 13 are used to divide the inner cavity of the hopper 6 into a plurality of equally divided spaces. The medicine will be evenly dispersed after the action of the plurality of guide plates 13 at the feed end of the medicine-sprinkling piece 10, thereby ensuring that the discharge from the discharge port of the medicine-sprinkling piece 10 is more uniform.

[0024] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
