Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a wastewater treatment device with a stirring mechanism. Background Technology

[0002] In wastewater treatment, the dosing and mixing of chemicals are crucial steps that directly affect the removal efficiency and treatment effect of pollutants. Common wastewater treatment chemicals include flocculants, coagulants, neutralizers, and oxidants. These chemicals need to be added at appropriate concentrations and times to ensure that the chemical reaction proceeds fully.

[0003] Traditional methods of chemical dosing typically involve adding the chemical to the wastewater all at once, then dispersing and reacting it through stirring. This method is simple to operate and suitable for treatment scenarios with relatively stable water quality and a relatively fixed amount of chemical consumption. However, a single dosing may result in localized excessively high or low chemical concentrations, affecting treatment effectiveness. For example, in flocculation and sedimentation, adding too much flocculant may cause excessive floc aggregation, affecting sedimentation and even leading to "reverse flocculation." Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a sewage treatment device with a stirring mechanism, which aims to alleviate the above problems to at least a certain extent.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A wastewater treatment device with a stirring mechanism includes:

[0007] A processing tower, wherein an inlet pipe and an outlet pipe are connected to the processing tower;

[0008] A circulation cylinder is installed inside the processing tower, and a circulation port is provided at the bottom of the circulation cylinder;

[0009] A reagent tank is located inside the processing tower, and the bottom of the reagent tank has multiple drug outlets;

[0010] A stirring shaft is provided inside the processing tower, and multiple stirring blades are connected to the outer wall of the stirring shaft;

[0011] A drive unit located between the processing tower and the stirring shaft is used to rotate the stirring shaft;

[0012] A release component located between the stirring shaft and the medicine tank is used to open and close the medicine outlet. The release component can intermittently open and close the medicine outlet when the stirring shaft rotates.

[0013] Preferably, the stirring shaft has an internal cavity, and the outer wall of the stirring shaft has a connection port communicating with the cavity. The stirring shaft is rotatably connected to the bottom of the liquid inlet pipe, and the cavity inside the stirring shaft is connected to the liquid inlet pipe.

[0014] Preferably, the drive unit includes a base connected to the bottom of the processing tower, a motor connected to the base, and the drive shaft of the motor connected to the stirring shaft.

[0015] Preferably, the release component includes a connecting rod slidably connected to the bottom of the medicine tank, the top of the connecting rod extending into the medicine tank and connected to a baffle, a spring connecting the baffle and the medicine tank, a connecting ring a connected to the bottom of the connecting rod, a connecting ring b connected to the stirring shaft, an inclined boss a connected to the connecting ring a, and an inclined boss b connected to the connecting ring b that mates with the inclined boss a.

[0016] Preferably, the medicine box is connected to multiple partitions, which divide the medicine box into multiple medicine chambers.

[0017] Preferably, the drug inlet tube is connected to the drug cavity.

[0018] In summary, the present invention has the following main advantages:

[0019] By installing an inlet pipe, the outlet pipe can be closed during application to inject wastewater into the treatment tower from the inlet pipe box. Reaction reagents can be added to the reagent tank. Initially, the outlet is closed, and the reagents remain in the tank. Specifically, during operation, the drive unit rotates the stirring shaft. As the shaft rotates, the stirring blades agitate the wastewater in the circulation tank. With stirring, the wastewater is propelled upwards by the blades, flowing back into the tank through the channel between the outer wall of the circulation tank and the inner wall of the treatment tower. This circulating flow creates a stable circulation path for the wastewater within the treatment tower. While the rotating stirring shaft circulates the wastewater between the circulation tank and the treatment tower, the release mechanism intermittently opens and closes the outlet, allowing the reagents to be added to the wastewater according to a preset cycle. When the release component opens the outlet, the liquid reagent flows into the treatment tower. As the stirring shaft continues to rotate, the reagent quickly mixes with the circulating wastewater, ensuring uniform distribution and reaction with pollutants. Because the reagent is added in batches, this method avoids over- or under-dosing, and the stirring and circulation maximizes reagent utilization and reaction efficiency. Each reagent addition is synchronized with the stirring action, ensuring even coverage of the entire wastewater volume and promoting a comprehensive chemical reaction. Once the reaction is complete, pollutants are effectively removed from the wastewater. After the treatment process, the user can control the inlet and outlet pipes to adjust the wastewater flow, ensuring the wastewater within the treatment tower undergoes a thorough reaction.

[0030] 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.

[0031] refer to Figures 1-5 A wastewater treatment device with a stirring mechanism, comprising:

[0032] The processing tower 100 is connected to an inlet pipe 101 and an outlet pipe 102.

[0033] A circulation cylinder 103 is installed inside the processing tower 100, and a circulation port 104 is provided at the bottom of the circulation cylinder 103;

[0034] A reagent tank 105 is located inside the treatment tower 100, and multiple reagent outlets 106 are provided at the bottom of the reagent tank 105.

[0035] A stirring shaft 107 is installed inside the processing tower 100, and a plurality of stirring blades 108 are connected to the outer wall of the stirring shaft 107.

[0036] A drive unit located between the processing tower 100 and the stirring shaft 107 is used to rotate the stirring shaft 107.

[0037] A release component located between the stirring shaft 107 and the reagent tank 105 is used to open and close the reagent outlet 106. The release component can intermittently open and close the reagent outlet 106 when the stirring shaft 107 rotates.

[0038] By providing the inlet pipe 101, the outlet pipe 102 can be closed during application to allow wastewater to be injected into the treatment tower 100. Reaction reagents can be added to the reagent tank 105. Initially, the outlet 106 is closed, allowing the reagents to remain in the reagent tank 105. Specifically, during operation, the drive unit rotates the stirring shaft 107. As the stirring shaft 107 rotates, the stirring blades 108 agitate the wastewater in the circulation cylinder 103. With stirring, the wastewater is pushed upwards by the stirring blades 108, and the rising wastewater then flows through the channel between the outer wall of the circulation cylinder 103 and the inner wall of the treatment tower 100 to the circulation port 104 at the bottom of the circulation cylinder 103, flowing back into the circulation cylinder 103. Through this circulation flow, a stable circulation path is formed within the treatment tower 100. While the stirring shaft 107 circulates, causing the wastewater to flow between the circulation cylinder 103 and the treatment tower 100, the release component intermittently opens and closes the outlet 106, allowing the liquid reagent to be added to the wastewater according to a preset cycle. When the release component opens the outlet 106, the liquid reagent flows into the treatment tower 100 through the outlet 106. As the stirring shaft 107 continues to rotate, the reagent quickly mixes with the circulating wastewater, ensuring that the reagent is evenly distributed in the wastewater and reacts with the pollutants. Because the reagent is added in batches, this method avoids over- or under-dosing of the reagent, and the stirring and circulation actions effectively improve the utilization efficiency and reaction effect of the reagent. Each addition of reagent is synchronized with the stirring action, ensuring that the reagent can evenly cover the entire wastewater body and promote the full chemical reaction. As the reaction is completed, the pollutants in the wastewater are effectively removed. After the treatment process is completed, the user can adjust the entry and discharge of sewage by controlling the switch of the inlet pipe 101 and the outlet pipe 102 to ensure that the sewage in the entire treatment tower 100 is fully reacted during the treatment process.

[0039] As a further part of this utility model, the stirring shaft 107 has a cavity 200 inside, and the outer wall of the stirring shaft 107 has a connection port 201 that communicates with the cavity 200. The stirring shaft 107 is rotatably connected to the bottom of the liquid inlet pipe 101, and the cavity 200 inside the stirring shaft 107 is connected to the liquid inlet pipe 101.

[0040] By designing the internal cavity 200 and connection port 201 of the stirring shaft 107, wastewater from the inlet pipe 101 can be directly introduced into the stirring shaft 107, and the wastewater is distributed to the stirring blades 108 outside the stirring shaft 107 through the flow in the cavity 200. In this way, after the wastewater enters the treatment tower 100, it is not only disturbed by the stirring blades 108, but also effectively guided to the area around the stirring blades 108 through the cavity 200 inside the stirring shaft 107, ensuring that each part of the wastewater is fully stirred and mixed.

[0041] As a further part of this utility model, the drive unit includes a base 202 connected to the bottom of the processing tower 100, a motor 203 connected to the base 202, and the drive shaft of the motor 203 connected to the stirring shaft 107.

[0042] By installing a motor 203, which powers the axial stirring shaft 107 to rotate continuously, the motor drives the stirring blades 108 to stir the wastewater in the circulation cylinder 103. This driving method ensures that the stirring shaft 107 operates at a predetermined speed and allows for adjustment of the speed and stirring intensity as needed to meet the treatment requirements of different wastewaters.

[0043] As a further part of this utility model, the release component includes a connecting rod 300 slidably connected to the bottom of the medicine tank 105, the top of the connecting rod 300 extending into the medicine tank 105 and connected to a baffle 301, a spring 302 connecting the baffle 301 and the medicine tank 105, a connecting ring a303 connected to the bottom of the connecting rod 300, a connecting ring b304 connected to the stirring shaft 107, an oblique boss a305 connected to the connecting ring a303, and an oblique boss b306 that cooperates with the oblique boss a305 connected to the connecting ring b304.

[0044] By setting a baffle 301, the baffle 301 can close the outlet 106 under the action of the spring 302, and the agent can be retained in the agent tank 105 in the initial state. When the sewage is injected into the treatment tower 100, the connecting ring b304 can rotate with the motor 203 when the stirring shaft 107 is rotated. When the connecting ring b304 rotates to a preset angle, the inclined boss b306 on it can contact and abut the inclined boss a305, allowing the connecting ring a303 to move upward. At this time, the baffle 301 leaves the outlet 106 and stretches the spring 302, and the liquid can be released from the outlet 106 into the treatment tower 100 to contact and mix with the sewage. The agent reacts with the sewage under the action of the rotation of the stirring shaft 107, thereby improving the treatment efficiency. Due to the design of the inclined bosses a305 and b306, the switching action of the release component can be precisely controlled according to the rotation of the stirring shaft 107, ensuring that the agent is added according to the predetermined cycle.

[0045] As a further part of this utility model, the medicine box 105 is connected with a plurality of partitions 400, which divide the medicine box 105 into a plurality of medicine cavities 401.

[0046] By setting multiple partitions 400, the reagent tank 105 is divided into multiple reagent chambers 401, each of which can store different types or concentrations of reagents. This design allows for the batch and on-demand dosing of various reagents, further improving the wastewater treatment effect.

[0047] As a further part of this utility model, a drug inlet tube 402 is connected to the drug cavity 401;

[0048] By setting up the inlet pipe 402, external liquid medicine can be delivered to each medicine chamber 401 inside the medicine tank 105.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
