Technical Field

[0001] This utility model relates to the field of wastewater dosing and stirring, specifically a dosing and stirring device for industrial wastewater treatment. Background Technology

[0002] Before adding the pharmaceutical solution to the industrial wastewater, it needs to be stirred and blended in a mixing tank to fully mix the raw pharmaceutical materials with the water in the specified proportion. After mixing, it is then added to the wastewater by extraction.

[0003] In existing technology, the outlet of the mixing tank is generally located at the bottom center. Therefore, some of the first added raw material will enter the inside of the outlet pipe. During the mixing process, this part of the raw material cannot be effectively mixed, which makes it easy for this part of the raw material to be incompletely mixed. Utility Model Content

The sealing head has a frustum-shaped structure that is wider at the top and narrower at the bottom, and a sealing ring is installed on the outer wall of the sealing head.

[0008] As a further improvement of this utility model: a hollow guide plate is welded to the lower inner wall of the mixing tank. The hollow guide plate has a conical structure that is wider at the top and narrower at the bottom. The narrow opening at the bottom of the hollow guide plate is aligned with the input end of the output pipe.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0017] Please see Figures 1-3In this embodiment of the present invention, a dosing and stirring device for industrial wastewater treatment includes a stirring tank 1. The top of the stirring tank 1 is detachably connected to a tank cover 2 by bolts. A dosing pipe 7 connected to the inner cavity of the stirring tank 1 is integrally formed on one side of the top of the tank cover 2. An input pipe 5 connected to the inner cavity of the stirring tank 1 is integrally formed on the other side of the top of the tank cover 2. An output pipe 6 extending to the outside of the stirring tank 1 is integrally formed at the center of the bottom end of the stirring tank 1. A stirring mechanism extending into the inner cavity of the stirring tank 1 is installed at the top of the output pipe 6. A sealing mechanism that penetrates the stirring mechanism and extends into the inner cavity of the stirring tank 1 is installed at the top of the stirring tank 1 to seal the input end of the output pipe 6.

[0018] In this embodiment: First, the raw materials and water in the specified proportion are added to the mixing tank 1 through the dosing pipe 7 and the input pipe 5, respectively. After the addition is completed, the stirring mechanism is started to fully stir the mixed raw materials to form a dosing liquid. During the dosing and stirring process, the sealing mechanism is in a sealing state to prevent some raw materials from entering the interior of the output pipe 6 and causing incomplete stirring and melting, thus ensuring the stirring and melting effect.

[0019] After mixing is complete, the sealing mechanism is moved upward by driving it to release the seal, and then the raw material can be output to be mixed with industrial wastewater for purification treatment.

[0020] Please refer to this carefully. Figure 1 and Figure 3 The stirring mechanism includes a stirring shaft 12 rotatably mounted at the center of the inside of the tank cover 2 and extending into the inner cavity of the stirring tank 1. A driven gear 11 is interference-fitted on the outer periphery of the stirring shaft 12, and a driving gear 10 meshes on the outer periphery of the driven gear 11. A stirring motor 3 is mounted on the top of the tank cover 2 via a bracket. The output shaft of the stirring motor 3 is coaxially connected to the center of the top of the driving gear 10. An agitator is mounted on the outer wall of the inner cavity of the stirring shaft 12.

[0021] In this embodiment: during the mixing process, the stirring motor 3 is started, the stirring motor 3 drives the drive gear 10 to rotate, the rotating drive gear 10 drives the driven gear 11 to rotate, the rotating driven gear 11 drives the stirring shaft 12 to rotate, and the stirring shaft 12 can drive the stirrer to fully mix the water and raw materials.

[0022] Please refer to this carefully. Figure 2 and Figure 3The sealing mechanism includes a lifting rod 13 that slides vertically and vertically within the inner cavity of the stirring shaft 12. The top end of the lifting rod 13 extends through to the top of the stirring shaft 12, and the bottom end extends through to the bottom of the stirring shaft 12. A sliding plate 8 is fixedly installed at the top end of the lifting rod 13, and a sealing head 14 is fixedly installed at the bottom end of the lifting rod 13. The sealing head 14 has a truncated cone structure that is wider at the top and narrower at the bottom. A sealing ring is installed on the outer wall of the sealing head 14. A hollow guide plate 15 is welded to the lower inner wall of the mixing tank 1. The hollow guide plate 15 has a conical structure that is wider at the top and narrower at the bottom. The narrow lower opening of the hollow guide plate 15 is aligned with the input end of the output pipe 6. The sealing head 14 is used to seal the narrow lower opening of the hollow guide plate 15.

[0023] In this embodiment: when the stirring shaft 12 rotates, the inner diameter of the stirring shaft 12 is slightly larger than the outer diameter of the lifting rod 13. Therefore, the rotating stirring shaft 12 will not drive the lifting rod 13 to rotate, and there will be no interference. Before adding the medicine, the electric push cylinder 4 is shortened by controlling the electric push cylinder 4 to drive the sliding plate 8 to move downward. The downward movement of the sliding plate 8 can drive the lifting rod 13 to move downward synchronously. The lifting rod 13 can then drive the sealing head 14 to seal the lower narrow opening of the hollow guide plate 15. At this time, the sealing ring is deformed by pressure, which improves the sealing performance between the sealing head 14 and the lower narrow opening of the hollow guide plate 15, preventing the raw material from entering the output pipe 6 and avoiding the phenomenon of incomplete melting of some raw materials.

[0024] After the stirring contact, the electric push cylinder 4 is extended, thereby pushing the sliding plate 8 to move upward. The sliding plate 8 can then drive the sealing head 14 to move upward via the lifting rod 13. At this time, the lower narrow opening of the hollow guide plate 15 is no longer blocked, and the stirred liquid can be discharged outward.

[0025] Please refer to this carefully. Figure 3 The top of the can lid 2 is fixedly installed with an upwardly protruding guide slide rod 9. The side lug of the sliding plate 8 is slidably connected to the outer wall of the guide slide rod 9. The top of the can lid 2 is equipped with an electric push cylinder 4 that is connected to the bottom of the sliding plate 8.

[0026] In this embodiment: during the up-and-down movement of the sliding plate 8, the guide rod 9 restricts the movement direction of the sliding plate 8 to avoid the sliding plate 8 from deviating from its movement.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
