Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an impurity separation device for wastewater treatment. Background Technology

[0002] Wastewater refers to wastewater discharged from domestic and industrial processes that has been polluted to a certain extent. The main methods of wastewater treatment include sedimentation, filtration, and adsorption. For example, in the primary sedimentation tank of a wastewater treatment plant, the wastewater flows slowly, and larger suspended particles gradually settle down. Filtration removes fine suspended solids and some organic matter from the wastewater through filter media. Adsorption uses the adsorption effect of adsorbents to remove pigments, odors, and some organic matter from the wastewater.

[0003] Existing wastewater treatment impurity separation devices generally use filtration equipment such as bar screens or filters to filter and intercept impurities in wastewater, thereby separating the impurities from the wastewater for subsequent wastewater treatment processes.

[0004] However, considering that the filter holes in the existing separation device are easily clogged by impurities in the sewage during long-term use, the sewage flow rate is reduced, which in turn reduces the working efficiency and effectiveness of the sewage treatment impurity separation device.

[0025] Reference Figure 1 and Figure 2The impurity separation device for wastewater treatment shown includes a housing 1, a separation mechanism 2, two collection mechanisms 3, and a switching mechanism 4. The separation mechanism 2 is fixedly installed inside the housing 1 and is used to separate impurities in the wastewater inside the housing 1. During the process of separating impurities from the wastewater inside the housing 1, the separation mechanism 2 can simultaneously clean the impurities attached to the filter frame 22, preventing the filter frame 22 from becoming clogged. The two collection mechanisms 3 are both fixedly installed inside the housing 1 and are used to collect the impurities separated from the wastewater inside the housing 1. The two collection mechanisms 3 can collect impurities at both ends of the inner side of the housing 1 at the same time. After collecting enough impurities, the mechanism reminds the staff to clean the impurities inside the housing 1 in a timely manner, thereby improving the effectiveness of the separation device. The switching mechanism 4 is fixedly installed on one side of the housing 1 and is used to open or close the opening on one side of the housing 1. The switching mechanism 4 can seal the gap between the cover plate 41 and the housing 1, improving the sealing effect of the housing 1.

[0026] Reference Figures 3 to 5 The separation mechanism 2 includes a push plate 21, a filter frame 22, a housing 23, an impeller 27, a rotating shaft 28, a connecting rod 29, and a hinge rod 210. The push plate 21 is slidably installed inside the housing 1. Through the sliding effect of the push plate 21, impurities on the filter frame 22 can be pushed onto the support plate 31, and the impurities attached to the filter frame 22 can be scraped and cleaned. The filter frame 22 is fixedly installed inside the housing 1. The filter frame 22 is n-shaped and can filter the sewage in the housing 1. The housing 23 is fixedly installed on the top of the inner side of the housing 1. The housing 23 is circular. The impeller 27 is rotatably mounted. Installed inside the housing 23, the rotation of the impeller 27 drives the rotating shaft 28 to rotate. The rotating shaft 28 passes through the housing 23 and is fixedly installed at the bottom of the impeller 27. The rotation of the rotating shaft 28 drives the connecting rod 29 to rotate. The connecting rod 29 is fixedly installed on the rotating shaft 28. The rotation of the connecting rod 29 drives the hinge rod 210 to reciprocate. One end of the hinge rod 210 is hinged to one end of the connecting rod 29, and the other end of the hinge rod 210 is hinged to one side of the push plate 21. The movement of the hinge rod 210 drives the push plate 21 to slide reciprocally.

[0027] Reference Figure 3 and Figure 5Each collection mechanism 3 includes a support plate 31, a spring 33, and a telescopic rod 34. The support plate 31 is slidably installed inside the housing 1. The support plate 31 collects impurities pushed by the push plate 21. As more impurities are collected, the support plate 31 gradually descends to compress the spring 33. One end of the spring 33 is fixedly installed at the bottom inside the housing 1, and the other end is fixedly installed at the bottom of the support plate 31. The elastic force of the spring 33 ensures that the support plate 31 remains slid upwards without external force. One end of the telescopic rod 34 is fixedly installed at the bottom inside the housing 1, and the other end of the telescopic rod 34... One end is fixedly installed at the bottom of the support plate 31. The spring 33 is sleeved on the telescopic rod 34. The telescopic rod 34 prevents the spring 33 from deforming when compressed, and at the same time guides the support plate 31. Each collection mechanism 3 also includes an indicator rod 32, which is fixedly installed at the top of the support plate 31. The movement of the support plate 31 can drive the indicator rod 32 to move vertically. The indicator rod 32 passes through the inner side of the top of the box 1. By observing the degree of descent of the indicator rod 32, the staff can understand the amount of impurities collected on the support plate 31, which facilitates the staff to clean and discharge the impurities in a timely manner.

[0028] Reference Figure 2 and Figure 6 The switching mechanism 4 includes two cover plates 41, two sealing gaskets 42, and a cylindrical rod 43. The bottom ends of the two cover plates 41 are hinged to one side of the housing 1. Through the hinge effect of the cover plates 41, the opening on the housing 1 can be opened or closed to clean impurities inside the housing 1. The two sealing gaskets 42 are respectively fixedly installed on the two cover plates 41. Through the setting of the sealing gaskets 42, when the cover plates 41 are closed, they can squeeze the sealing gaskets 42 against the housing 1, so that the sealing gaskets 42 seal the gap between the housing 1 and the cover plates 41. One end of the cylindrical rod 43 is fixedly installed on one cover plate 41, and the other end of the cylindrical rod 43 is fixedly installed on the other cover plate 41. The two cover plates 41 are connected by the cylindrical rod 43, which makes it convenient for the operator to open or close the two cover plates 41 at the same time.

[0029] Reference Figure 6 and Figure 7The switching mechanism 4 also includes a fixing block 44, a wedge 45, a return spring 46, and a latch 47. The fixing block 44 is fixedly installed on the cylindrical rod 43. The wedge 45 is slidably installed on the inner side of the fixing block 44. Through the sliding effect of the wedge 45, the wedge 45 and the latch 47 can be engaged or disengaged. One end of the return spring 46 is fixedly installed on the inner side of the fixing block 44, and the other end of the return spring 46 is fixedly installed on the wedge 45. Through the elastic force of the return spring 46, the wedge 45 always maintains the engagement effect with the latch 47 when no external force is applied, thereby limiting the cover plate 41. The latch 47 is fixedly installed on one side of the housing 1, and the wedge 45 is engaged with the inner side of the latch 47.

[0030] Reference Figure 1 and Figure 3 The separation mechanism 2 also includes an inlet pipe 24, an outlet pipe 25, and a drain pipe 26. The inlet pipe 24 is fixedly installed on one side of the housing 23 and passes through the box 1. Through the inlet pipe 24, sewage can enter the housing 23 and impact the impeller 27, thereby causing the impeller 27 to rotate. The outlet pipe 25 is fixedly installed on the other side of the housing 23. Through the outlet pipe 25, sewage in the housing 23 can be discharged into the box 1 for filtration and separation. The drain pipe 26 is fixedly installed on the other side of the box 1. Through the drain pipe 26, sewage in the box 1 after impurity separation can be discharged from the box 1 to the outside. The bottom of the push plate 21 contacts the top of the filter frame 22.

[0031] This wastewater treatment impurity separation device can separate impurities from wastewater inside the tank through its separation mechanism. A push plate can clean impurities adhering to the filter frame, preventing clogging and improving the device's efficiency and effectiveness. Furthermore, the collection and switching mechanisms allow for the collection of separated impurities, facilitating subsequent cleaning and further enhancing the device's performance.
