Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a flow rate uniformity control device for sewage oxidation treatment. Background Art

[0002] With the increase of environmental awareness and the importance of environmental protection, sewage treatment has received more and more attention. Sewage treatment processes are often diverse, among which oxidation treatment of sewage is one of the commonly used treatment methods. For example, a mixed gas of oxygen and ozone is filled into the sewage, oxidized, and then introduced into the sedimentation chamber for sufficient oxidation, sedimentation and separation, and then the separated water is pumped out to the next treatment process by a water pump. However, the commonly used extraction method is to use a water pump to extract water, which results in a long wait for the sewage to fully complete sedimentation and separation before extraction, and if the extraction speed is adjusted according to the oxidation speed, it is easy to cause the water flow to become rapid, thereby causing the incompletely deposited substances to diffuse and be extracted together, affecting the separation efficiency and quality.

[0003] In view of this, the applicant filed this application after studying the existing technology. Utility Model Content

By setting up two sedimentation chambers to separate the sewage after oxidation, and then using two pumps to extract the water after oxidation and sedimentation separation from the two sedimentation chambers, diversion extraction is achieved, and the water flow during extraction is relatively gentle, ensuring that the total extraction volume is high while the extracted water can be fully oxidized and separated. The pumping speed of the primary pump and the secondary pump can also be adjusted to correspond to the oxidation rate, so as to evenly control the sufficient oxidation and sedimentation time of the water in the water inlet cylinder, ensuring that the final water flow can be fully oxidized and separated before entering the buffer bin, and the separation extraction efficiency is higher.

[0007] As a further optimization, a guide tube is provided in the secondary sedimentation chamber, the input end of the guide tube is connected to the port of the through hole, and the output end is located at the bottom of the secondary sedimentation chamber.

[0008] As a further optimization, a filter cage is provided in the secondary sedimentation chamber, the input end of the filter cage is connected to the output end of the guide pipe, and a filter is provided at the upper end of the filter cage. The filter cage is provided to preliminarily separate the sediments and prevent the sediments from spreading due to the impact of water flow.

[0009] As a further optimization, the cross section of the filter cage is arranged in an arc shape, thereby sufficiently increasing the filter area at the upper end of the filter cage.

[0010] As a further optimization, a connecting pipe is further provided in the secondary sedimentation chamber, which is provided at one end of the filter cage. The connecting pipe is provided in an arc shape and is respectively connected to the guide pipe and the inside of the filter cage.

[0011] As a further optimization, two connection holes are provided on both sides of one end of the connecting pipe close to the filter cage, and the connection holes are connected to the filter cage, so that when the water flows into the filter cage, the impact on the sediment near the bottom is reduced.

[0012] As a further optimization, the flow rate at which the secondary pump pumps water into the secondary sedimentation chamber is higher than the flow rate at which the primary pump pumps water into the primary sedimentation chamber.

[0013] As a further optimization, a solenoid valve is provided between the buffer bin and the water outlet cylinder. The mixed flow of the buffer bin allows the water flowing into the water outlet cylinder to remain uniform, so as to facilitate the subsequent sewage treatment.

Therefore, the following detailed description of the implementation mode of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents the selected implementation mode of the utility model. Based on the implementation mode in the utility model, all other implementation modes obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] Depend on Figures 1 to 3As shown, the embodiment of the utility model provides a flow rate uniformity control device for sewage oxidation treatment, including a water inlet cylinder 1 and a water outlet cylinder 2, an oxidation chamber 3 is arranged at one end of the water inlet near the water inlet, and a device for oxidizing sewage entering from the water inlet is arranged in the oxidation chamber 3, such as a gas oxidation device (not shown in the figure), which will not be described here. Preferably, a primary sedimentation chamber 4 and a secondary sedimentation chamber 5 are also arranged in the water inlet cylinder 1, the primary sedimentation chamber 4 is connected to the bottom end of the oxidation chamber 3, a partition 6 is arranged between the primary sedimentation chamber 4 and the secondary sedimentation chamber 5, and a through hole 7 is arranged at the center of the partition 6; it also includes a primary pump 8, a secondary pump 9 and a buffer bin 10, the input ends of the primary pump 8 and the secondary pump 9 are respectively connected to the primary sedimentation chamber 4 and the secondary sedimentation chamber 5, and are respectively arranged at the top of the primary sedimentation chamber 4 and the secondary sedimentation chamber 5, and the output ends are respectively connected to the buffer bin 10; the output end of the buffer bin 10 is connected to the water outlet cylinder 2; the input end of the secondary pump 9 is fixedly connected to an extension pipe 11, and the input end port of the extension pipe 11 is lower than the height of the through hole 7. Among them, it is preferred that the flow rate of the secondary pump 9 pumping water in the secondary sedimentation chamber 5 is higher than the flow rate of the primary pump 8 pumping water in the primary sedimentation chamber 4. In this way, the sewage is initially deposited in the primary sedimentation chamber 4 after oxidation, and due to the rise of the water level, the sediment is initially separated from the water, and the water potential slows down. At this time, the water flow will first enter the secondary sedimentation chamber 5 through the through hole 7, so as to further extend the oxidation and sedimentation time, and further slow down the sedimentation, and the secondary pump 9 extends to the position of the secondary sedimentation chamber 5 below the through hole 7 through the extension pipe 11 to pump water, so that the water in the primary sedimentation chamber 4 will first be guided to the secondary sedimentation chamber 5, and then gradually rise to the level close to the primary pump 8 for pumping water, and because the pumping speed of the secondary pump 9 is relatively low, it is sufficient to extract the water that has completed sufficient oxidation and sedimentation separation in the primary sedimentation chamber 4, and the water that has not been fully oxidized and deposited will be guided to the secondary sedimentation chamber 5 to extend the sedimentation time, thereby achieving diversion extraction, realizing a relatively gentle water flow during extraction, and ensuring that the total extraction volume is high, and the extracted water can fully complete the oxidation and sedimentation separation. And when the water inlet volume of the water inlet cylinder 1 is large, when the oxidation rate of the oxidation equipment is increased in the oxidation chamber 3, the oxidation rate can be controlled by adjusting the pumping speed of the first-stage pump 8 and the second-stage pump 9, so as to evenly control the sufficient oxidation and sedimentation time of the water in the water inlet cylinder 1, and ensure that the water flow can be sufficiently oxidized, deposited and separated before entering the buffer bin 10.

[0023] Preferably, a guide tube 12 is provided in the secondary sedimentation chamber 5, the input end of the guide tube 12 is connected to the port of the through hole 7, and the output end is located at the bottom of the secondary sedimentation chamber 5. By providing the guide tube 12, the water in the primary sedimentation chamber 4 enters the secondary sedimentation chamber 5 from the bottom of the secondary sedimentation chamber 5, so that when the water gradually rises in the secondary sedimentation chamber 5, the slow flow effect can be better enhanced, and the time for the water flow in the water inlet cylinder 1 can be extended to ensure that it completes sufficient oxidation sedimentation separation.

[0024] Furthermore, a filter cage 13 is provided in the secondary sedimentation chamber 5, the input end of the filter cage 13 is connected to the output end of the guide pipe 12, and a filter 14 is provided at the upper end of the filter cage 13. When the water flows into the secondary sedimentation chamber 5 from the guide pipe 12, the water flowing in will impact the sediment. By providing the filter cage 13, not only the space for depositing mixed water can be limited to prevent the sediment from being impacted and re-spreading, but also the sediment can be initially filtered out to facilitate the subsequent cleaning of the sediment. The filter cage 13 can also slow down the water flow when the water flows through, further completing the sediment separation.

[0025] Preferably, the cross section of the filter cage 13 is arranged in an arc shape. In this way, the filter cage 13 can be adapted to the arc-shaped bottom of the water inlet cylinder 1, the surface area of ​​the filter 14 through which water flows at the upper end is increased, and the pumping speed of the secondary pump 9 is ensured.

[0026] Preferably, a connecting pipe 15 is further provided in the secondary sedimentation chamber 5, which is provided at one end of the filter cage 13. The connecting pipe 15 is arranged in an arc shape, and the connecting pipe 15 is connected to the guide pipe 12 and the inside of the filter cage 13 respectively. Furthermore, two connecting holes 16 are provided on both sides of the connecting pipe 15 near the end of the filter cage 13, and the connecting holes 16 are connected to the filter cage 13. By providing the connecting pipe 15 as a connection method between the filter cage 13 and the guide pipe 12, water can enter the filter cage 13 from the connecting holes 16 at higher positions on both sides of the arc when entering the filter cage 13. Because the filter cage 13 is arranged in an arc shape, the sediment will be stacked toward the lower middle part, and the water flow entering from the higher parts on both sides can reduce the impact on the sediment, thereby reducing the diffusion of the sediment caused by the impact of the water flow.

[0027] Preferably, a solenoid valve 17 is provided between the buffer bin 10 and the water outlet cylinder 2. The solenoid valve 17 is provided to control the speed of the flow from the buffer bin 10 to the water outlet cylinder 2, and the flow can be converged through the buffer cavity and then directed to the water outlet cylinder 2 to ensure that the substances in the water body are uniform, so as to cope with the subsequent sewage treatment process.

[0028] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
