Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater treatment device for uniformly mixing chemical solutions. Background Technology

[0002] Wastewater treatment refers to the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Adding chemicals to wastewater treatment processes is a key step in optimizing treatment effectiveness and improving water quality compliance rates. Through the reaction of chemicals with substances in the wastewater, flocculation, sedimentation, and stratification occur, thereby achieving the purpose of wastewater treatment.

[0003] Currently, wastewater treatment agents are generally in solid granular form. To prevent these agents from clumping in the wastewater, they must first be dissolved into liquid form (e.g., PAM needs to be prepared as a 0.1%-0.5% solution). This increases the number of treatment steps and reduces wastewater treatment efficiency. Furthermore, when a small amount of agent is poured into a large amount of wastewater, the agent cannot disperse quickly enough, resulting in uneven mixing of the agent and wastewater and reducing reaction efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the prior art by proposing a wastewater treatment device for uniformly mixing chemicals, so as to facilitate the full mixing of chemicals and wastewater and improve wastewater treatment efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A wastewater treatment device for uniformly mixing pharmaceutical solutions, comprising:

[0007] shell;

[0008] A rotating rod, which is rotatably connected to the inside of the outer casing;

[0009] Multiple mixing mechanisms are arranged around the outside of the rotating rod. Each mixing mechanism includes a vertical pipe with an inlet pipe at the lower end. The rotating rod rotates to drive the inlet pipe to rotate around the circumference of the rotating rod. The inlet of the inlet pipe is parallel to the tangent of the circumference of the rotating rod so that when the inlet pipe rotates, sewage enters the inlet pipe and sprays out from the upper end of the vertical pipe. The inlet pipe is horizontally arranged and is arc-shaped.

[0010] A dosing mechanism, which is mounted on the outer casing and located above the vertical pipe, for adding chemicals to the top of the vertical pipe;

[0011] The lower end of the rotating rod is provided with multiple fixed rods at intervals along its circumference. A rotating sleeve is rotatably connected to each fixed rod. A scraper is provided on the outside of the rotating sleeve. The rotating sleeve rotates so that one side of the scraper tilts downward so that its lower edge fits against the bottom wall of the outer shell.

[0012] Furthermore, each vertical pipe has an outlet pipe at its upper end, which is hook-shaped and has its outlet facing the center of the outer shell, so that the sewage mixes in the center of the outer shell.

[0013] Furthermore, a fixing cylinder is provided on the top of the outer shell, the fixing cylinder is located in the center of the outer shell, and the dosing mechanism is set on one side of the fixing cylinder so that the agent falls into the center of the outer shell through the fixing cylinder.

[0014] Furthermore, the dosing mechanism includes a feed cylinder, a hopper, and a screw rod. The feed cylinder is located on one side of the fixed cylinder, and a connecting pipe is provided between the feed cylinder and the fixed cylinder. The screw rod is rotatably connected to the inside of the feed cylinder, and the hopper is located at the top of the feed cylinder.

[0015] Furthermore, both the upper end of the rotating rod and one end of the screw rod are equipped with bevel gears, and the two bevel gears mesh.

[0016] Furthermore, the upper end of the rotating rod passes through the fixed cylinder, and a stirring rod is provided on the outside of the rotating rod, with the stirring rod located inside the fixed cylinder.

[0017] Furthermore, a drain pipe is provided on one bottom side of the outer casing.

[0018] Furthermore, it also includes a drive motor, which is mounted on the housing, and the output shaft of the drive motor is connected to the rotating rod.

[0019] The beneficial effects of this utility model are as follows:

[0020] In this invention, the wastewater treatment device for uniformly mixing chemicals uses a rotating rod to drive a vertical pipe that agitates the wastewater inside the outer shell. Additionally, it drives the inlet pipe to rotate around the circumference of the rotating rod, allowing wastewater to enter the inlet pipe and then the vertical pipe. Guided by the outlet pipe, the wastewater mixes in the center of the outer shell. At this time, the chemicals falling from the fixed cylinder fall into the mixing area and are thoroughly mixed with the wastewater under the action of the water flow, improving the mixing efficiency of the chemicals and wastewater.

[0030] Reference Figure 1-4 A wastewater treatment device for uniformly mixing chemicals is used in wastewater treatment to improve the mixing effect of chemicals and wastewater and increase wastewater treatment efficiency.

[0031] The wastewater treatment device for uniformly mixing chemicals includes a housing 1, a rotating rod 2, multiple mixing mechanisms, and a dosing mechanism;

[0032] An opening is provided on one side of the top of the outer casing 1, and a sealing plate is provided at the opening. Wastewater to be treated can be added into the interior of the outer casing 1 through the opening. Two drain pipes 101 are provided on the bottom side of one side of the outer casing 1. After the medicine and wastewater mix and produce sediment, the clear water on the top can be discharged through the upper drain pipe 101, while the sludge sediment at the bottom can be discharged through the lower drain pipe 101.

[0033] The rotating rod 2 is rotatably connected to the inside of the outer shell 1. Multiple mixing mechanisms are arranged around the outside of the rotating rod 2. Each mixing mechanism includes a vertical pipe 3. The lower end of the vertical pipe 3 is provided with a water inlet pipe 301. The water inlet pipe 301 is horizontally arranged and is arc-shaped.

[0034] Reference Figure 1 When the rotating rod 2 rotates, it drives the vertical pipe 3 to rotate around the rotating rod 2. At this time, the vertical pipe 3 can stir the sewage inside the outer shell 1. In addition, it will also drive the water inlet pipe 301 to rotate around the circumference of the rotating rod 2. Since the inlet of the water inlet pipe 301 is parallel to the tangent of the circumference of the rotating rod 2, the sewage can enter the water inlet pipe 301 when the water inlet pipe 301 rotates, and then enter the vertical pipe 3, and be sprayed out from the top of the vertical pipe 3, realizing the vertical circulation of sewage.

[0035] In some embodiments, each vertical pipe 3 has an outlet pipe 302 at its upper end. The outlet pipe 302 is hook-shaped, and the outlet of each outlet pipe 302 faces the center of the outer casing 1. Wastewater flows upward inside the vertical pipe 3 and is guided by the outlet pipe 302, thereby mixing the wastewater at the center of the outer casing 1. Since multiple mixing mechanisms are evenly arranged along the outside of the rotating rod 2, wastewater from all directions of the outer casing 1 is impacted and mixed at the center of the outer casing 1, improving the mixing effect of the agent.

[0036] A fixed cylinder 6 is provided on the top of the outer casing 1, and the fixed cylinder 6 is located at the center of the outer casing 1. The upper end of the rotating rod 2 passes through the fixed cylinder 6. A drive motor 5 is provided on the outer casing 1, and the drive motor 5 is fixedly mounted on the fixed cylinder 6, and the output shaft of the drive motor 5 is connected to the rotating rod 2. The drive motor 5 can drive the rotating rod 2 to rotate.

[0037] The dosing mechanism is located on one side of the fixed cylinder 6. The dosing mechanism includes an inlet cylinder 4, a hopper 401, and a screw rod 403. The inlet cylinder 4 is located on one side of the fixed cylinder 6, and a connecting pipe 402 is provided between the inlet cylinder 4 and the fixed cylinder 6. The screw rod 403 is rotatably connected to the inside of the inlet cylinder 4, and the hopper 401 is located at the top of the inlet cylinder 4. Chemicals are added into the hopper 401, falling into the inlet cylinder 4 and being laterally conveyed by the rotating screw rod 403. This allows the chemicals to fall through the connecting pipe 402 into the wastewater inside the outer casing 1. The connecting pipe 402 not only conveys the chemicals but also provides support for the inlet cylinder 4, thereby enhancing its structural stability.

[0038] Reference Figure 2 The agent can enter the fixed cylinder 6 through the connecting pipe 402, and finally fall into the interior of the outer shell 1 through the fixed cylinder 6. Since the fixed cylinder 6 is located in the center of the outer shell 1, the agent will fall to the center of the outer shell 1. At this time, the mixing mechanism causes the sewage from all directions of the outer shell 1 to collide and mix in the center of the outer shell 1. The agent falls into the mixing area, and the impact force of the water flow not only improves the mixing effect, but also, in this embodiment, solid agents can be used. Solid agents falling into the sewage mixing area can be quickly impacted and mixed by the water flow, effectively avoiding agent clumping, thereby saving the solid agent dissolution process and improving the sewage treatment effect.

[0039] In some embodiments, a stirring rod 201 is provided outside the rotating rod 2, and the stirring rod 201 is located inside the fixed cylinder 6. When the agent falls inside the fixed cylinder 6, the stirring rod 201 rotates with the rotating rod 2, thereby stirring the falling agent. In particular, when solid agents fall, they can be broken up to prevent clumping and facilitate their dissolution in wastewater.

[0040] Both the upper end of the rotating rod 2 and one end of the screw rod 403 are equipped with bevel gears 404, which mesh together. Through the transmission of the bevel gears 404, the rotating rod 2 can drive the screw rod 403 to rotate.

[0041] In addition, it is convenient to remove the sludge deposits inside the outer casing 1.

[0042] In some embodiments, the lower end of the rotating rod 2 is provided with a plurality of fixed rods 702 spaced apart along its circumference, and a rotating sleeve 701 is rotatably connected to each fixed rod 702. A scraper 7 is provided on the outside of the rotating sleeve 701, and the rotating sleeve 701 is located on the top of one side of the scraper 7.

[0043] Reference Figure 3-4 When the rotating rod 2 drives the mixing mechanism to rotate counterclockwise, the wastewater is fully mixed with the reagent through the mixing mechanism. At this time, since the scraper 7 can rotate freely outside the fixed rod 702 through the rotating sleeve 701, the scraper 7 moves with the rotating rod 2 inside the wastewater and remains horizontal under the action of water flow, only stirring the wastewater. When the sedimentation is completed and the treated wastewater is discharged, the rotating rod 2 drives the scraper 7 to rotate clockwise. At this time, under the action of gravity, one side of the scraper 7 tilts downward and its lower edge is attached to the bottom wall of the outer shell 1. The scraper 7 continues to rotate, which can scrape up the sludge settled on the bottom wall of the outer shell 1, making it easier for the sludge to be discharged and treated.

[0044] The working principle of this wastewater treatment device with uniformly mixed chemicals is as follows: wastewater to be treated is added to the inside of the outer shell 1, and chemicals are added to the inside of the hopper 401.

[0045] The drive motor 5 drives the rotating rod 2 to rotate counterclockwise. The rotating rod 2 drives the spiral rod 403 to rotate through the bevel gear 404. The spiral rod 403 causes the agent to fall into the fixed cylinder 6 through the connecting pipe 402 and enter the sewage inside the outer shell 1 through the fixed cylinder 6.

[0046] Simultaneously, the rotating rod 2 drives the vertical pipe 3 to rotate around the rotating rod 2, and the vertical pipe 3 can stir the sewage inside the outer shell 1. In addition, it will also drive the inlet pipe 301 to rotate around the circumference of the rotating rod 2, so that the sewage enters the inlet pipe 301, and then enters the vertical pipe 3. Guided by the outlet pipe 302, the sewage is mixed in the center of the outer shell 1. Since multiple mixing mechanisms are evenly arranged along the outside of the rotating rod 2, the sewage from all directions of the outer shell 1 is impacted and mixed in the center of the outer shell 1. The agent falling inside the fixed cylinder 6 falls into the mixing area and is fully mixed with the sewage under the action of water flow.

[0047] When sedimentation is complete, the treated wastewater is discharged through the upper drain pipe 101. Then, the rotating rod 2 drives the scraper 7 to rotate clockwise. At this time, under the action of gravity, one side of the scraper 7 is tilted downward and its lower edge is attached to the bottom wall of the outer shell 1. The scraper 7 continues to rotate, which can scrape up the sludge settled on the bottom wall of the outer shell 1. Finally, the sludge is discharged through the lower drain pipe 101.

[0048] 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.
