Description

Technical Field

[0001] The invention belongs to the technical field of sewage treatment, and in particular relates to municipal sewage filtering equipment. Background Art

[0002] Municipal wastewater treatment is the process of centralized treatment of wastewater discharged by urban residents and industrial production activities. These wastewaters contain various organic, inorganic, microbial and other pollutants such as grease, suspended solids, nutrients (such as nitrogen and phosphorus) and harmful chemicals. Municipal wastewater treatment aims to reduce these pollutants in wastewater to safe levels through a series of process steps so that they can be safely discharged into the natural environment or reused. The pretreatment stage is used to remove large particles such as paper, cloth, etc. in wastewater. Heavy particles such as sand, mud, gravel, etc. are removed from wastewater by gravity sedimentation. The primary treatment stage is to use gravity to settle suspended matter in wastewater to the bottom to form sludge. Floating materials (such as grease, suspended solids) in wastewater are floated by gas injection for subsequent treatment. The biological treatment stage is to use facultative or aerobic microorganisms to biodegrade organic matter. The biofilm on the surface of the filter material is used to degrade organic matter and remove nutrients such as nitrogen and phosphorus. The advanced treatment stage is to use materials such as sand filtration and activated carbon to remove residual suspended matter, colloidal matter and organic matter. Disinfection is the use of chlorine, ozone or ultraviolet light to kill residual bacteria and pathogenic microorganisms to ensure the safety of treated water. Recycling is the high-pressure dialysis of treated water to remove dissolved salts and organic matter to meet the standards for reuse. The main purpose of municipal wastewater treatment is to protect the environment and public health, reduce pollution to natural water bodies, and effectively recycle and utilize water resources. This requires sophisticated equipment, strict operational control and monitoring to ensure that the treated water quality meets national and local discharge standards.

[0027] In one embodiment of the present invention, a sewage inlet 2 is provided on one side of the municipal sewage filter body 1, and a water outlet 8 is provided on the side of the municipal sewage filter body 1 away from the sewage inlet 2; a sprayer 15 is fixedly connected to one side of the reciprocating sliding plate 14, and a purifier box 27 is fixedly connected to the side of the reciprocating sliding plate 14 away from the sprayer 15; by using a driving filter acceleration component, the rotating disc 19 can be driven to rotate, and the connecting block 25 is fixed on the rotating disc 19, so the rotating disc 19 will also drive the connecting block 25 to rotate, and the connecting block 25 will also drive the second sliding plate 23 to rotate, and the rotation of the second sliding plate 23 will drive the rotating plate 21 to rotate, and at the same time, the rotating plate 21 will drive the reciprocating sliding plate 14 to move left and right, so that the cleaning plate 16 can move on the sewage filter plate 9 to clean the sewage filter plate 9, to prevent the sewage filter plate 9 from being blocked and affecting the overall use effect.

[0028] like Figure 1 and Figure 3 As shown, as a preferred embodiment of the present invention, the driving filter acceleration component includes a No. 2 driving motor 17; the No. 2 driving motor 17 is fixedly connected to one side of the fixed plate 10, and a rotating shaft 24 is installed at the end of the output end of the No. 2 driving motor 17; and an arc-shaped fan blade 20 is installed on the outer side wall of the rotating shaft 24.

[0029] Specifically, start the No. 2 drive motor 17. Since the rotating shaft 24 is installed at the end of the output end of the No. 2 drive motor 17, the No. 2 drive motor 17 will drive the rotating shaft 24 to rotate. The rotating shaft 24 will also drive the arc-shaped fan blades 20 to rotate, so that the arc-shaped fan blades 20 can promote faster filtration of municipal sewage, thereby improving the overall use effect.

[0031] The filter grid 11 is used to filter larger substances in the municipal sewage. The filter grid 11 is movably connected to the inside of the municipal sewage filter body 1.

[0032] The grille adjustment mechanism is used to adjust the angle of the filter grille 11 based on the horizontal plane.

[0033] Specifically, the grille adjustment mechanism can better adjust the grille to a suitable position, so that it can capture large particles to the maximum extent, prevent them from entering the subsequent processing stage, and improve the overall use efficiency.

[0034] like Figure 2 and Figure 4 As shown, as a preferred embodiment of the present invention, the grille adjustment mechanism includes a sliding block 12; a No. 1 fixing block 3 is fixedly connected inside the municipal sewage filter body 1; a rotating threaded rod 4 is rotatably connected to one side of the No. 1 fixing block 3; the outer wall of the rotating threaded rod 4 and the sliding block 12 are threadedly connected; the filter grille 11 is rotatably connected to the sliding block 12; a No. 1 driving motor 13 is fixedly connected inside the municipal sewage filter body 1; the end of the output end of the No. 1 driving motor 13 is connected to the rotating threaded rod 4 through the sliding block 12; a supporting component for supporting the filter grille 11 is arranged outside the filter grille 11.

[0035] Specifically, the number of the No. 1 fixed block 3, the rotating threaded rod 4 and the sliding block 12 are all two groups; by starting the No. 1 driving motor 13, the No. 1 driving motor 13 can drive the rotating threaded rod 4 to rotate through the sliding block 12. The rotating threaded rod 4 and the sliding block 12 are threadedly connected, so the rotation of the rotating threaded rod 4 will also drive the sliding block 12 to move, so that the sliding block 12 can drive the filter grid 11 to rotate, so that the filter grid 11 can be adjusted to a suitable angle, so that the filter grid 11 can capture large particles to the maximum extent and prevent them from entering the subsequent processing stage. At the same time, the support assembly will also support the filter grid 11 to make it more stable.

[0036] like Figure 3As shown, as a preferred embodiment of the present invention, the support assembly includes a No. 2 fixed block 6; the No. 2 fixed block 6 is fixedly connected to the inside of the municipal sewage filter body 1; one side of the No. 2 fixed block 6 is rotatably connected to a rotating support rod 5; the rotating support rod 5 is rotatably connected to one side of the filter grid 11.

[0037] Specifically, when the filter grid 11 rotates, the second fixing block 6 can better support the filter grid 11 by rotating the support rod 5 to prevent the filter grid 11 from shaking, thereby improving the overall stability.

[0038] like Figure 3 As shown, as a preferred embodiment of the present invention, it also includes:

[0039] The filtering vibration mechanism is used to allow the sewage filtering plate 9 to vibrate to prevent it from being blocked and affecting the municipal sewage treatment.

[0042] Specifically, when filtering municipal sewage, the sewage filter plate 9 will give a force to the limit spring 26, causing the limit spring 26 to be compressed. When compressed to a certain extent, the limit spring 26 will also give a force to the sewage filter plate 9 to move it, so that the sewage filter plate 9 can shake to prevent it from being blocked, thereby improving the overall use efficiency.

[0043] Working principle: By starting the No. 1 driving motor 13, the No. 1 driving motor 13 can drive the rotating threaded rod 4 to rotate through the sliding block 12. The rotating threaded rod 4 and the sliding block 12 are threadedly connected, so the rotation of the rotating threaded rod 4 will also drive the sliding block 12 to move, so that the sliding block 12 can drive the filter grid 11 to rotate, so that the filter grid 11 can be adjusted to a suitable angle, so that the filter grid 11 can capture large particles to the maximum extent and prevent them from entering the subsequent processing stage. At the same time, when the filter grid 11 rotates, the No. 2 fixed block 6 can better support the filter grid 11 by rotating the support rod 5 to prevent it from shaking, thereby improving the overall stability; start the No. 2 driving motor 17, since the rotating shaft 24 is installed at the end of the output end of the No. 2 driving motor 17, the No. 2 driving motor 17 will drive the rotating shaft 24 to rotate, and the rotating shaft 24 will also drive the arc-shaped fan blades 20 to rotate, so that the arc-shaped fan blades 20 can promote Municipal sewage is filtered faster, and the rotation of the arc-shaped fan blades 20 will also drive the rotating disc 19 to rotate. The connecting block 25 is fixed on the rotating disc 19, so the rotating disc 19 will also drive the connecting block 25 to rotate, and the connecting block 25 will also drive the second sliding plate 23 to rotate, and the rotation of the second sliding plate 23 will drive the rotating plate 21 to rotate, and the rotating plate 21 will drive the reciprocating sliding plate 14 to move left and right, so that the cleaning plate 16 can move on the sewage filter plate 9 to clean the sewage filter plate 9, and prevent the sewage filter plate 9 from being blocked and affecting the overall use effect; and when filtering municipal sewage, when the sewage filter plate 9 is impacted by municipal sewage, it will give a force to the limit spring 26, so that the limit spring 26 is compressed. When compressed to a certain extent, the limit spring 26 will also give a force to the sewage filter plate 9 to move it, so that the sewage filter plate 9 can shake to prevent it from being blocked, thereby improving the overall use efficiency.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
