Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment, and in particular to a multi-stage wastewater treatment device. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering, and is increasingly becoming a part of everyday life. Common treatment methods include physical, chemical, and biological methods. When using chemical methods to treat domestic wastewater, it is usually necessary to add some chemicals. Therefore, wastewater treatment agent mixing devices play an important role. However, conventional wastewater treatment agent mixing devices have some drawbacks. The amount of wastewater treated varies each time, making it impossible to control the amount of treatment agent. This requires manual addition, and the addition ratio depends on the operator's experience, which can easily lead to excessive or insufficient treatment agent. Utility Model Content

[0003] The purpose of this invention is to design a multi-stage sewage treatment device to solve the above-mentioned problems.

[0004] This utility model achieves the above objectives through the following technical solutions:

[0005] A multi-stage wastewater treatment device, comprising:

[0006] Multiple mixing chambers; adjacent mixing chambers are connected by connecting pipes, and each mixing chamber is used for the treatment of wastewater with one treatment agent;

[0007] Multiple treatment agent additives; one set of treatment agent additives is used to add a treatment agent into a mixing chamber;

[0008] The first trench; the first trench is used to add wastewater into the mixing chamber located at the very front;

[0009] Control component; the control component includes a first control element and a plurality of second control elements, wherein the control action end of the first control element is located in the first groove;

[0010] Multiple first valves;

[0011] Each treatment agent additive unit includes a storage chamber, at least one transfer chamber, and a second trench. The storage chamber is used to store the treatment agent. The inlet and outlet of the second trench are connected to the outlet of the storage chamber and the inlet of the first transfer chamber, respectively.

[0025] Multiple mixing treatment chambers 1; adjacent mixing treatment chambers 1 are connected by connecting pipes 15, and one mixing treatment chamber 1 is used for the treatment of wastewater by one treatment agent;

[0026] Multiple sets of treatment agent additives; one set of treatment agent additives is used to add a treatment agent to a mixing treatment chamber 1;

[0027] First trench 2; First trench 2 is used to add sewage into the mixing and treatment chamber 1 located at the foremost end;

[0028] Control component; The control component includes a first control element and a plurality of second control elements, wherein the control action end of the first control element is located in the first groove 2;

[0029] Multiple first valves 16;

[0030] Each set of treatment agent additives includes a storage chamber 7, at least one transfer chamber 10, and a second trench 4. The storage chamber 7 is used to store the treatment agent. The inlet and outlet of the second trench 4 are connected to the outlet of the storage chamber 7 and the inlet of the transfer chamber 10, respectively. The outlet of the transfer chamber 10 is connected to the inlet of the mixing chamber 1 via a connecting hose 13. A second valve 11 is provided at the outlet of the transfer chamber 10. The control end of a second control element is located in a second trench 4. Both the first trench 2 and the second trench 4 are inclined. The first valve 16 is installed... At the inlet of the first groove 2 or the inlet of the second groove 4, the first valve 16 installed at the inlet of the first groove 2 is not shown in the figure; when the treatment agent additive includes multiple transfer chambers 10, the multiple transfer chambers 10 are connected in sequence, and a second valve 11 is provided between two adjacent transfer chambers 10. The first mixing treatment chamber and the second mixing treatment chamber are respectively provided with one transfer chamber, and subsequent mixing treatment chambers are respectively provided with multiple transfer chambers. For example, the nth mixing treatment chamber is respectively connected with n-2 transfer chambers in sequence, where n is a positive integer greater than 2.

[0031] Both the first and second control components include:

[0032] Control board 3; Control board 3 is rotatably mounted on the upper end of the first groove 2 or the second groove 4, with the first end of control board 3 located inside the first groove 2 or the second groove 4;

[0033] Elastic element 9; the first end of elastic element 9 is fixedly set on the fixed surface, and the second end of elastic element 9 acts on control plate 3. The angle between the direction of the elastic force of elastic element 9 on control plate 3 and the flow direction of sewage in the first trench 2 is an obtuse angle. When there is no sewage flow in the first trench 2, the first end of control plate 3 is in contact with the bottom of the first trench 2 or the second trench 4. When there is sewage flow in the first trench 2, the distance between the first end of control plate 3 and the bottom of the first trench 2 or the second trench 4 is greater than zero. The rotation angle of each control plate 3 is the same. Under the action of elastic element 9 and sewage and control plate 3, the rotation angle of control plate 3 is controlled by the instantaneous sewage inflow. When the instantaneous sewage inflow is large, the opening of control plate 3 is large, and when the instantaneous sewage inflow is small, the opening of control plate 3 is small.

[0034] A rubber pad is provided at the first end of the control board 3.

[0035] The elastic element 9 is a compression spring, and the second end of the compression spring acts on the first end of the control plate 3.

[0036] The control assembly also includes a linkage shaft 8 and multiple connecting plates 12. The linkage shaft 8 is rotatably mounted on the first groove 2 and the second groove 4. Multiple control plates 3 are fixedly mounted on the linkage shaft 8, and multiple connecting plates 12 are fixedly mounted on the linkage shaft 8.

[0037] The elastic element 9 is a tension spring, and the second end of the tension spring acts on the connecting plate 12.

[0038] The angle between the first groove 2 and the second groove 4 and the horizontal plane is less than 45°.

[0039] Each mixing chamber 1 is equipped with a stirrer 6, and the rotation center of the stirrer 6 is fixedly connected to the rotating shaft of the motor 5.

[0040] Each connecting pipe 15 is equipped with a third valve 14.

[0041] When the addition ratio of the treatment agent needs to be changed, it can be achieved by changing the tilt angle of the first groove 2 or the second groove 4, or by changing and controlling the cross-sectional width of the fluid channel of the first groove 2 or the second groove 4 through other structures or by setting the cross-sectional width of the fluid channel.

[0042] The working principle of this multi-stage wastewater treatment equipment is as follows:

[0043] When wastewater needs to be treated, the first valve 16 is opened simultaneously. When the wastewater passes through the control plate 3, the force between the wastewater and the control plate 33 causes the first end of the control plate 33 to rotate in the direction of water flow. At this time, the control plate 3 in the first groove 2 drives the linkage shaft 8, the control plate 3 in the second groove 4, and the connecting plate 12 to rotate together at the same angle, and the tension spring is stretched again to store energy. When enough or all of the wastewater has been added to the control plate 3 in the first groove 2, the first valve 16 is closed, and the squeezing force between the wastewater and the control plate 3 is reduced to zero. Under the force of the tension spring restoring its deformation, the first end of the control plate 3 rotates in the opposite direction, so that the rubber pad at the first end of the control plate 3 squeezes and contacts the bottom of the first groove 2 or the bottom of the second groove 4, thereby blocking the addition of treatment agent. Here, the amount of all treatment agents added is controlled. When a treatment agent needs to be added later, the second valve 11 of the corresponding storage treatment agent transfer chamber 10 can be opened. When the wastewater to be treated completely enters the first groove 2, the first valve 16 is closed. In mixing chamber 1, all second valves 11 are opened to allow the corresponding treatment agent to enter. After completion, the second valves 11 are closed. After the wastewater has been treated in one mixing chamber 1, the third valve 14 is opened to allow the wastewater from the previous mixing chamber 1 to enter the next mixing chamber 1 through the connecting pipe 15. After entry, the third valve 14 is closed and the first valve 16 is opened, allowing the wastewater to enter the first wastewater treatment chamber again. The treatment agent enters the transfer chamber 10, waiting for the wastewater in the corresponding mixing chamber 1 to be treated before entering the next mixing chamber 1. At this time, the second valve 11 is opened to add the treatment agent for the current batch of wastewater into the mixing chamber 1. After the treatment agent in the transfer chamber 10 is discharged, the next batch of wastewater is added to the mixing chamber 1 at the front end through the first trough 2. At this time, the treatment agent in the storage chamber 7 is fed into the transfer chamber 10. Therefore, the treatment agent in the transfer chamber 10 is used to treat the next batch of wastewater, realizing the parallel treatment of wastewater by different treatment agents, saving wastewater treatment time to the greatest extent.

[0044] When treating wastewater, the working state of motor 5 is controlled according to actual needs, so that agitator 6 can stir the wastewater in mixing treatment chamber 1.

[0045] Use the three mixing chambers 1 shown in the attached drawings of this utility model, and number the mixing chambers sequentially as ①②③;

[0046] With the second valve 11 and the third valve 14 closed and the first valve 16 open, the first batch of wastewater enters the first mixing chamber 1 through the first trough 2. During this process, the storage chamber 7 feeds into the transfer chamber 10. The first transfer chamber 10, located below the storage chamber, contains the treatment agent for treating the first batch of wastewater. After the first batch of wastewater has entered, the first valve 16 and the third valve 14 are closed, and the second valve 11 is open. The treatment agent in the transfer chamber 10 is simultaneously added to the corresponding first and second mixing chambers 1. The treatment agent above the third mixing chamber 1 enters the second transfer chamber from the first transfer chamber. The first valve 16, the second valve 11, and the third valve 14 are closed. Then, the first mixing chamber 1 treats the first batch of wastewater, while the second and third mixing chambers 1 are idle.

[0047] ① After the first batch of wastewater in mixing chamber 1 is treated by the first treatment agent, the first valve 16 and the second valve 11 are closed, and the third valve 14 is open. The first batch of wastewater enters mixing chamber 1 ② through the third valve 14 and the connecting pipe 15, where it is treated by another treatment agent. After entering, the second valve 11 and the third valve 14 are closed, and the first valve 16 is open. The second batch of wastewater enters mixing chamber 1 ① through the first trench 2. During this process, storage chamber 7 feeds into the first transfer chamber 10, which contains the treatment agent for treating the second batch of wastewater. ③ The second transfer chamber 10 of mixing chamber 1 contains the treatment agent for treating the first batch of wastewater. The first valve 16, the second valve 11, and the third valve 14 are closed. At this time, mixing chamber 1 ② treats the first batch of wastewater, mixing chamber 1 ① treats the second batch of wastewater, and mixing chamber 1 ③ is idle.

[0048] ① After the second batch of wastewater in mixing treatment chamber 1 is treated by the first treatment agent, and ② after the first batch of wastewater in mixing treatment chamber 1 is treated by the second treatment agent, the first valve 16 and the second valve 11 are closed, controlling the working state of the third valve 14, and sequentially completing the process of the first batch of wastewater entering ③ mixing treatment chamber 1 through the third valve 14 and the connecting pipe 15. After entering, the second batch of wastewater then enters ② mixing treatment chamber 1 through the third valve 14 and the connecting pipe 15. After entering, the first valve 16 and the third valve 14 are closed, and the second valve 11 is open, allowing the second batch of treatment agent in transfer chamber 10 to enter the next transfer chamber 10 or ② mixing treatment chamber 1.

[0049] The second valve 11 and the third valve 14 are closed, and the first valve 16 is open. The third batch of wastewater enters the first mixing chamber 1 through the first trough 2. During this process, the storage chamber 7 feeds into the transfer chamber 10. The uppermost transfer chamber 10 contains the treatment agent for treating the third batch of wastewater. The first valve 16, the second valve 11, and the third valve 14 are closed. At this time, the second mixing chamber 1 treats the second batch of wastewater, the first mixing chamber 1 treats the third batch of wastewater, and the third mixing chamber 1 treats the first batch of wastewater. The first transfer chamber 10 corresponding to the third mixing chamber 1 contains the treatment agent for treating the third batch of wastewater, and the second transfer chamber 10 contains the treatment agent for treating the second batch of wastewater. Subsequent batches of wastewater are recycled in the same manner.
