Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a low-energy consumption urban sewage advanced treatment device. Background Art

[0002] Urban sewage refers to domestic sewage, industrial wastewater and runoff sewage within the urban area. Urban sewage contains various types and degrees of various toxic and harmful pollutants. Direct discharge will cause serious pollution to the environment and even harm to the human body in severe cases. To avoid the above situation, people will filter and meet the standards for urban sewage before discharging it. When discharging sewage into the urban pipeline, most communities will first conduct a simple cleaning. According to most filtering devices, there is basically no way to clean the filter screen, which will lead to problems such as blockage of the drainage pipeline after the filter screen is blocked and damage caused by high-intensity extrusion of the filtering device. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to provide a low-energy consumption urban sewage advanced treatment device that can quickly process blocked impurities without stopping filtration to solve the problems mentioned in the background.

An inlet and outlet are provided on the top surface of the fixed frame, and a strip-shaped opening is provided on the bottom surface of the fixed frame. A panel is inserted into the inlet and outlet and the strip-shaped opening. Multiple installation openings are provided on the panel, and connection frames are arranged in the installation openings. Filter nets are installed inside the connection frames. The upper filter net is located inside the fixed frame, and pressing plates for squeezing out the water inside the intercepted impurities are installed on both sides of the section of the panel located inside the fixed frame through hinge parts.

[0005] As a preferred technical solution, multiple drainage grooves are provided on the inner side surfaces of the pressing plates. Top plates are installed on the left and right above the panel.

[0019] All features disclosed in this specification, or all steps in the disclosed methods or processes, except for mutually exclusive features and / or steps, can be combined in any way.

[0020] Any feature disclosed in this specification (including any additional claims, abstract, and drawings), unless specifically stated, can be replaced by other equivalent or similar-purpose alternative features. That is, unless specifically stated, each feature is only an example of a series of equivalent or similar features.

[0021] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, a low-energy consumption advanced treatment device for urban sewage of the present utility model includes a fixed frame 1 for installation in the middle of a sewage pipe. An inlet / outlet 12 is provided on the top surface of the fixed frame 1, and a strip-shaped opening 13 is provided on the bottom surface of the fixed frame 1. A panel 2 is inserted into the inlet / outlet 12 and the strip-shaped opening 13. A plurality of installation openings are provided on the panel 2, and connection frames 3 are arranged in the installation openings. Filter nets 4 are installed inside the connection frames 3. The upper filter net 4 is located inside the fixed frame 1. Pressing plates 7 for squeezing out the moisture inside the intercepted impurities are installed on both sides of the part of the panel 2 located inside the fixed frame 1 through hinge members; among them, the filter net here is composed of multiple filter nets, generally composed of a coarse filter net, a medium filter net, a fine filter net, and an activated carbon filter net in combination to ensure the effect of deep filtration.

[0022] In this embodiment, a plurality of drainage grooves 8 are provided on the inner side surfaces of the pressing plates 7. Top plates 6 are installed on the left and right above the panel 2. The bottom surface of the top plate 6 abuts against the top surface of the fixed frame 1, and a plurality of magnets are embedded in the bottom surface of the top plate 6. The lower ends of the magnets are adsorbed and fixed on the top surface of the fixed frame 1.

[0023] In this embodiment, first screw holes are provided on both sides of the pressing plates 7. Second screw holes are provided on the pressing plates 7 opposite to the first screw holes. Bolts 11 are threadedly connected in the opposite first screw holes and second screw holes.

[0024] In this embodiment, the lower connection frames 3 are directly fixed in the installation openings. A plurality of positioning holes are provided on both sides of the upper connection frames 3. Insertion holes are provided on both side surfaces of the panel 2 opposite to the positioning holes. Positioning rods are inserted into the opposite insertion holes and positioning holes, and the outer side surfaces of the positioning rods abut against the inner side surfaces of the fixed frame 1;

[0025] Among them, after the panel moves upward, the outside of the positioning hole can move away from the inner side surface of the fixed frame. At this time, the positioning rod can be directly taken outwards. After losing the block of the positioning rod, the connecting frame and the internal filter net can be directly taken out, which facilitates the replacement of the filter net to ensure the filtering effect.

[0026] In this embodiment, the width of the inlet and outlet 12 is greater than the width of the strip-shaped opening 13. The width of the strip-shaped opening 13 matches the width of the panel 2, and a rubber layer is installed on the inner side surface of the strip-shaped opening 13. The rubber layer is in contact with the outer side surface of the panel 2. The rubber layer increases the sealing performance between the strip-shaped opening. Among them, a cover body that covers the exposed end of the lower end of the panel is installed at the lower end of the fixed frame.

[0027] In this embodiment, connecting flanges 5 with a frame structure are installed at both ends of the fixed frame 1.

[0028] In this embodiment, a socket 9 for inserting a hand is provided on the panel 2.

[0029] The fixed frame can be arranged between sewage pipes and is fixedly connected to the sewage pipes through the cooperation of bolts and nuts, so that sewage can pass through between the fixed frames. The passing sewage can be filtered by the filter net, and the filtered impurities will be intercepted by the filter net. After long-term use, a large amount of impurities will remain on one side surface of the filter net, and these impurities will affect the filtering effect. Therefore, the upper end of the panel can be held by hand and the panel can be lifted upward, so that the panel moves upward along the strip-shaped opening. Before moving, the bolts need to be unscrewed to avoid being unable to move upward due to the existence of the pressing plate;

[0030] As the panel moves, the pressing plate will be squeezed by the inlet and outlet, causing the pressing plate to rotate downward around the hinge, and the downward-rotating pressing plate can squeeze the impurities inward, so that the water inside the impurities flows out along the drainage groove, avoiding the water in the impurities from being carried out, and the volume of the impurities can be reduced by the squeezing method, which facilitates subsequent storage;

[0031] Among them, as the panel moves upward, the lower filter net can replace the upper filter net to ensure the continuity of filtration, avoid stopping, and ensure the working effect.

[0032] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any change or replacement that is thought of without creative labor should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
