Description

Technical Field

[0001] The utility model relates to the field of sewage treatment equipment, in particular to an anti-clogging sewage treatment device. Background Art

[0002] A sewage treatment plant is a facility used to treat and purify domestic sewage, industrial wastewater or agricultural drainage. The main purpose of a sewage treatment plant is to reduce pollutants in sewage, such as suspended solids, organic matter, nitrogen, phosphorus and pathogens, to protect water bodies from pollution and maintain ecological balance. Through effective sewage treatment, the treated water can be used for agricultural irrigation, industrial water, urban landscape water, etc., to achieve the recycling of water resources. Sewage treatment plants help reduce the risk of waterborne diseases, improve public health conditions and protect human health. With the advancement of technology, sewage treatment technology is also constantly developing, including innovations in physical, chemical and biological treatment methods, as well as the application of energy recovery and resource utilization technologies. Sewage treatment plants are an indispensable infrastructure in modern society. They play a key role in environmental protection, water resources management, public health and sustainable development. With the continuous advancement of technology and increasingly stringent environmental regulations, the design and application of sewage treatment plants will continue to develop to meet the growing environmental and economic needs.

[0003] The simple structure of a sewage treatment plant usually includes the following basic components to achieve effective sewage treatment: an inlet system, which is responsible for introducing sewage into the treatment plant and may include grilles and screens to remove large particles of solids; a sedimentation tank, which uses gravity to settle suspended solids in sewage and separate solids and liquids; a biological treatment area, which uses microorganisms to degrade organic matter in sewage and may include an activated sludge system or a biofilm reactor; a disinfection area, which kills pathogens through disinfectants or ultraviolet rays to ensure that treated water meets safe discharge standards; and an outlet system, which discharges treated water and includes filtration and disinfection steps.

[0004] The sewage in the current sewage treatment system on the market needs to be initially filtered to remove large particles of impurities in the sewage during circulation. However, due to the large amount of impurities in the sewage, it is extremely easy to clog the filter. The current solution is to improve the performance and size of the filter, but this method is ultimately limited and too expensive. Therefore, a sewage treatment device that can prevent clogging is designed. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide an anti-clogging sewage treatment device to solve the technical problem that traditional devices are prone to clogging and will affect the sewage treatment efficiency.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a kind of anti-clogging sewage treatment device comprises a main pipeline, a main filtering device is installed on the main pipeline, and a filter is installed inside the main filtering device, the outer wall of the main pipeline is located at the front end of the main filtering device and is connected to a secondary pipeline, and the end of the secondary pipeline away from the main pipeline is connected to the detection pipeline, and the outer wall of the detection pipeline is connected to an auxiliary pipeline, and the auxiliary pipeline is connected to the main pipeline at the rear end of the main filtering device, the inner wall of the detection pipeline slides in contact with a limiting block, and a spring is connected between the limiting block and the tail end of the inner wall of the detection pipeline, the limiting block cooperates with the connection between the detection pipeline and the auxiliary pipeline, an auxiliary filtering device is installed on the auxiliary pipeline, and a filter is also installed inside the auxiliary filtering device, the inner diameter of the secondary pipeline is smaller than the inner diameter of the main pipeline, and the filter is provided with a grid-shaped polypropylene and a ceramic with a small pore size.

[0007] By adopting the above technical solution, when the filter of the main filtering device in the main pipeline is blocked, the main pipeline cannot flow at the main filtering device. At this time, the sewage flows into the auxiliary pipeline, squeezing the limit block in the detection pipeline backward until the connection between the detection pipeline and the auxiliary pipeline leaks out. At this time, the sewage is filtered through the filter of the auxiliary filtering device in the auxiliary pipeline and re-enters the main pipeline.

[0008] The utility model is further configured as follows: the interior of the main filter device is located on both sides of the corresponding filter and is in close sliding contact with sealing plates, and the sealing plates cooperate with the corresponding filters and the main pipeline, one end of the main filter device is rotatably connected to a first double-ended gear shaft meshing with one end of the two sealing plates, and the first double-ended gear shaft passes through the main filter device toward one end of the auxiliary filter device, the auxiliary filter device is rotatably penetrated by a second double-ended gear shaft at the same end as the first double-ended gear shaft, and the bottom end of the second double-ended gear shaft is meshed with the first double-ended gear shaft, the interior of the auxiliary filter device is located above the corresponding filter and is rotatably connected to a spiral fan blade, a transmission belt is sleeved between the spiral fan blade and the top end of the second double-ended gear shaft, and an opening for facilitating the disassembly of the corresponding filter is opened at one end of the main filter device away from the first double-ended gear shaft.

[0009] By adopting the above technical solution, as the filter of the main filtering device becomes clogged, the sewage drives the spiral blades in the auxiliary filtering device to rotate, thereby driving the sealing plate to gradually rise through the transmission belt, the first double-ended gear shaft, and the second double-ended gear shaft, and as the sealing plate rises, the efficiency of sewage passing through the main filtering device further decreases, and the flow rate of sewage through the auxiliary filtering device is further increased. The rotation speed of the spiral blades is also increased, further accelerating the rising speed of the sealing plate, and this is repeated until the sealing plate is completely closed. At this time, the clogged filter is removed through the opening of the main filtering device for replacement, and the blockage of the main pipeline is handled.

[0010] In summary, the utility model mainly has the following beneficial effects:

[0011] When the filter of the main filtering device is clogged, the sewage flows into the auxiliary pipeline, pressing the limit block in the detection pipeline to retreat until the connection between the detection pipeline and the auxiliary pipeline leaks out. At this time, the sewage is filtered by the filter of the auxiliary filtering device in the auxiliary pipeline and re-enters the main pipeline. With the complete closure of the sealing plate, the clogged filter is removed through the opening of the main filtering device for replacement, thereby completing the processing of the blockage in the main pipeline.

The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

An auxiliary filter device 7 is installed on the auxiliary pipeline 4, and a filter 5 is also installed inside the auxiliary filter device 7. The inner diameter of the auxiliary pipeline 2 is smaller than the inner diameter of the main pipeline 1. The filter 5 is provided with a grid-shaped polypropylene and a ceramic with a small pore size. When the filter 5 of the main filter device 6 in the main pipeline 1 is blocked, the main pipeline 1 cannot flow at the main filter device 6. At this time, the sewage rushes to the auxiliary pipeline 2, squeezing the limit block 13 in the detection pipeline 3 to retreat until the connection between the detection pipeline 3 and the auxiliary pipeline 4 leaks out. At this time, the sewage is filtered through the filter 5 of the auxiliary filter device 7 in the auxiliary pipeline 4 and re-enters the main pipeline 1.

[0020] The interior of the main filter device 6 is located on both sides of the corresponding filter 5 and is in close sliding contact with sealing plates 8, and the sealing plates 8 cooperate with the corresponding filter 5 and the main pipeline 1. One end of the main filter device 6 is rotatably connected to a first double-ended gear shaft 10 meshing with one end of the two sealing plates 8, and the first double-ended gear shaft 10 passes through the main filter device 6 toward one end of the auxiliary filter device 7, and the auxiliary filter device 7 is rotatably penetrated by a second double-ended gear shaft 11 at the same end as the first double-ended gear shaft 10, and the bottom end of the second double-ended gear shaft 11 is meshed with the first double-ended gear shaft 10. The interior of the auxiliary filter device 7 is located above the corresponding filter 5 and is rotatably connected to a spiral blade 9. A transmission belt 12 is sleeved between the spiral blade 9 and the top of the second double-ended gear shaft 11. The main filter device 6 is away from the second filter device 7. An opening is provided at one end of a double-ended gear shaft 10 for facilitating the disassembly of the corresponding filter 5. As the filter 5 of the main filter device 6 becomes clogged, the sewage drives the spiral blades 9 in the auxiliary filter device 7 to rotate, thereby driving the sealing plate 8 to gradually rise through the transmission belt 12, the first double-ended gear shaft 10, and the second double-ended gear shaft 11. As the sealing plate 8 rises, the efficiency of sewage passing through the main filter device 6 further decreases, and the flow rate of sewage through the auxiliary filter device 7 is further increased. The rotation speed of the spiral blades 9 is also increased, further accelerating the rising speed of the sealing plate 8, and this process is repeated until the sealing plate 8 is completely closed. At this time, the clogged filter 5 is removed through the opening of the main filter device 6 for replacement, and the blockage of the main pipeline 1 is handled.

[0021] Working principle: when the filter 5 of the main filter device 6 in the main pipeline 1 is blocked, the main pipeline 1 cannot flow at the main filter device 6. At this time, the sewage rushes to the auxiliary pipeline 2, squeezing the limit block 13 in the detection pipeline 3 to retreat until the connection between the detection pipeline 3 and the auxiliary pipeline 4 leaks out. At this time, the sewage is filtered through the filter 5 of the auxiliary filter device 7 in the auxiliary pipeline 4 and re-enters the main pipeline 1. At this time, the sewage drives the spiral blades 9 in the auxiliary filter device 7 to rotate, thereby driving the sealing plate 8 to gradually rise through the transmission belt 12, the first double-end gear shaft 10, and the second double-end gear shaft 11. As the sealing plate 8 rises, the passing efficiency of the sewage in the main filter device 6 is further reduced, and the flow rate of the sewage through the auxiliary filter device 7 is further increased. The rotation speed of the spiral blades 9 is also increased, further accelerating the rising speed of the sealing plate 8, and so on and so forth until the sealing plate 8 is completely closed. At this time, the blocked filter 5 is removed and replaced through the opening of the main filter device 6, and the blockage of the main pipeline 1 is handled.
