Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for sewage treatment, specifically an operation and maintenance device for an ecological filter bed used in sewage treatment. Background Technology

[0002] With increasingly stringent environmental protection requirements, wastewater treatment technology is constantly developing towards higher efficiency and ecological sustainability. Ecological filters, as a type of green wastewater treatment facility, purify water quality through the synergistic effect of microorganisms, plants, and packing materials. They have advantages such as low energy consumption and less secondary pollution. However, during long-term operation, existing ecological filters will accumulate a large amount of debris, such as fallen leaves, which will settle to the bottom of the filter, causing filter media blockage and pollutant accumulation. Furthermore, due to their weight, they cannot be cleaned by backwashing and require manual scraping with tools, resulting in low maintenance efficiency and potential disruption to the ecological balance of the filter. Utility Model Content

[0005] A pair of mounting plates are installed on the top platform of the ecological filter tank. A pair of linear module translation platforms are installed on the pair of mounting plates. A pair of moving platforms are installed on the moving ends of the pair of linear module translation platforms. A pair of moving bracket assemblies are installed on the pair of moving platforms and the ecological filter tank. Two pairs of lifting push rods are installed on the pair of moving bracket assemblies. A lifting platform is installed on the output ends of the two pairs of lifting push rods. The filter box is installed on the lifting platform through a pair of mounting brackets. The purification chamber is opened inside the filter box. The filter grid is installed inside the purification chamber. The suction pipe is installed on the front wall of the filter box. The suction pump is installed at the outlet on the rear wall of the filter box. Several drain pipes are installed on the suction pump.

[0013] Beneficial effects

[0014] This utility model provides an operation and maintenance device for an ecological filter bed in wastewater treatment, which has the following beneficial effects: This solution uses a drive-adjustable suction purification structure, which realizes fully automatic mechanical filter bed cleaning and maintenance through the drive structure. Through the coordinated action of the linear module translation platform and the lifting push rod, the suction purification structure is driven to move flexibly in the horizontal and vertical directions, achieving full-area coverage cleaning of the filter bed, suctioning away deposited sludge without dead corners, significantly improving maintenance efficiency. It can also be adaptively adjusted according to the water level depth of the filter bed. The filter box is equipped with a purification chamber and a detachable filter screen. The suctioned wastewater is discharged through a drain pipe after multi-stage filtration, effectively... This system separates solid impurities, prevents secondary clogging, and extends the service life of the filter. The mobile support assembly, through the cooperation of sliding rails and support sliders, ensures the stability of the suction structure during movement. It also adapts to the installation environment of the filter sidewall, enhancing the reliability of the device's operation. This solves the problem that in existing ecological filters, during long-term operation, a large amount of fallen leaves and other debris will drift into the filter and settle to the bottom, causing filter media blockage and pollutant accumulation. Furthermore, due to their weight, these debris cannot be cleaned by backwashing and require manual scraping with tools, resulting in low maintenance efficiency and potential disruption to the filter's ecosystem balance.

Detailed Implementation

[0020] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Example: Please refer to Figure 1-4 This utility model provides a technical solution: an operation and maintenance device for an ecological filter for sewage treatment. This solution takes into account that existing ecological filters will have debris and garbage settling at the bottom of the filter during use, and the backwashing system cannot effectively clean them. Manual cleaning and maintenance are required, which is inefficient. Based on the above, this invention sets up the following technical means.

[0022] Specifically, this device includes at least: an ecological filter 1, a pair of mounting plates 2, a pair of linear module translation platforms 3, a pair of moving platforms 4, a pair of moving support assemblies, two pairs of lifting push rods 5, a lifting platform 6, a pair of mounting brackets 7, a filter box 8, a purification chamber 9, a filter grid 10, a suction pipe 11, a suction pump 12, and several drainage pipes 13.

[0023] Each pair of movable support assemblies includes: a movable frame 18, a sliding rail 19, and a support slider 20;

[0024] The ecological filter 1 serves as the main body of the equipment, providing installation and support for the entire system. During maintenance and use, the equipment is started by operating a controller that matches the equipment. The linear module translation platform 3, mounted on the mounting plate 2 and installed on the ecological filter 1, moves the equipment to the end of the ecological filter 1. The height of the lifting platform 6 is adjusted by extending and retracting the output end of the lifting push rod 5 according to the height of the filter media at the bottom of the ecological filter 1, ensuring that the bottom of the suction pipe 11 is just above the filter media. The linear module translation platform 3 then moves the entire equipment to the other end of the ecological filter 1. During this movement, the lower end of the moving frame 18 is supported by a sliding mechanism. Block 20 moves within the sliding track 19 to provide auxiliary support for the equipment and ensure stable movement. Simultaneously, the suction pump 12 installed behind the filter box 8 starts, creating negative pressure in the purification chamber 9. Under pressure, water from the ecological filter 1 enters the purification chamber 9 through the suction pipe 11, thereby drawing the sediment at the bottom into the purification chamber 9. The sediment is then filtered by the filter grid 10 installed in the purification chamber 9. The filtered water is then drained back into the ecological filter 1 through the drain pipe 13 via the suction pump 12, thus achieving fully automatic adjustable filter purification and maintenance.

[0025] More specifically, a pair of mounting plates 2 are installed on the top platform of the ecological filter tank 1, a pair of linear module translation platforms 3 are installed on the pair of mounting plates 2, a pair of moving platforms 4 are installed on the moving ends of the pair of linear module translation platforms 3, a pair of moving bracket assemblies are installed on the pair of moving platforms 4 and the ecological filter tank 1, two pairs of lifting push rods 5 are installed on the pair of moving bracket assemblies, a lifting platform 6 is installed on the output ends of the two pairs of lifting push rods 5, a filter box 8 is installed on the lifting platform 6 through a pair of mounting brackets 7, a purification chamber 9 is opened inside the filter box 8, a filter grid 10 is installed inside the purification chamber 9, a suction pipe 11 is installed on the front wall of the filter box 8, a suction pump 12 is installed at the outlet of the rear wall of the filter box 8, and several drain pipes 13 are installed on the suction pump 12;

[0026] The mobile frame 18 is installed on the mobile platform 4, the sliding rail 19 is installed on the side wall of the ecological filter pool 1, and the support slider 20 is installed at the lower end of the mobile frame 18 and is movably embedded in the sliding rail 19.

[0027] In the specific implementation process, furthermore, a pair of mobile platforms 4 are connected to the mobile ends of a pair of linear module translation stages 3 via connecting rods 14.

[0028] In the specific implementation process, a pair of mounting brackets 7 are further installed on the lifting platform 6 by fixing bolts 15.

[0029] In the specific implementation process, the suction pump 12 is further installed on the filter box 8 via the mounting bracket 16.

[0030] In the specific implementation process, the filter grille 10 is further installed in the purification chamber 9 by the limiting stop bar 17.

[0031] In the specific implementation process, furthermore, the two pairs of lifting push rods 5 are installed on the side wall of the movable frame 18 through the mounting block 21.
