Description

Technical Field

[0001] This application relates to the field of wastewater treatment technology, specifically to a wastewater treatment ecological filter. Background Technology

[0002] Ecological filters for wastewater treatment are an ecological technology that utilizes the synergistic effects of microorganisms, plants, and packing materials to purify wastewater. They adsorb and retain suspended solids through a microbial membrane, and rely on the oxygen transport of well-developed wetland plants and the decomposition of organic matter by microorganisms to form a stable and efficient wastewater treatment system. They are characterized by low energy consumption, ease of maintenance, and high ecological integration, making them particularly suitable for rural or small-scale decentralized wastewater treatment scenarios. However, traditional filters, due to their top-opening natural ventilation design, are prone to excessive rainwater infiltration during heavy rainfall. This not only dilutes the wastewater concentration and disrupts the hydraulic load but may also alter the temperature, dissolved oxygen, and pH value within the filter, leading to suppressed microbial community activity or structural imbalance. This reduces pollutant degradation efficiency and may even cause fluctuations in effluent quality.

[0003] Therefore, this application proposes a wastewater treatment ecological filter that automatically covers the top of the filter to prevent rainwater from entering during heavy rain and can release gases produced by microorganisms. Utility Model Content

[0004] The purpose of this utility model is to provide an ecological filter for sewage treatment, which aims to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a wastewater treatment ecological filter, comprising a pool body with an opening at the top, and a shield provided on the side of the opening to prevent rainwater from entering the filter. The shield is unfolded by a drive mechanism to cover the opening at the top of the pool body.

[0006] The shield includes two sets of folding plates, which are fixedly connected in the middle by a horizontal plate. A non-powered vent is provided on the horizontal plate, extending to the lower part of the horizontal plate. The drive mechanism drives the folding plates to move horizontally along the transverse side of the pool. The folding plates are stretched by the drive to cover the upper end of the pool. The horizontal plate is displaced by the drive to the middle of the upper end of the pool. The non-powered vent rotates to discharge the gas reacting in the pool.

[0007] During heavy rain or other extreme weather, the drive mechanism moves the folding plate horizontally to cover the top of the filter tank, preventing rainwater from entering. At the same time, the nitrogen and other gases generated by the microbial reaction in the filter tank are discharged by the pressure difference between the inside and outside and the external wind force, which causes the non-powered wind cap to rotate. This effectively reduces the impact of extreme weather on the activity of the microbial community in the filter tank and prevents excessive accumulation of nitrogen in the tank, thus effectively ensuring the treatment effect of the ecological filter tank on sewage under harsh weather conditions.

[0008] Furthermore, the bottom wall of the tank is equipped with evenly distributed pipes, each with an array of aeration discs. The pipes pass through the side of the tank and are interconnected. An air pump is installed at the end of each pipe. Fixed rods are evenly inserted into the side wall of the tank, with biofilm inserted at the bottom of each rod. The side wall of the tank is also equipped with inlet pipes for water intake and outlet pipes for water drainage.

[0009] Furthermore, the upper end of the pool body has two receiving grooves on both sides, and the receiving grooves have mounting plates at both ends. The upper end of the pool body is also fixedly connected to a limiting rail. The cover plate is slidably connected to the limiting rail. The lower end of the limiting rail has a through slot, and the upper wall inside the limiting rail is welded and fixed with a limiting block.

[0010] Furthermore, the drive mechanism includes two sets of threaded rods, threaded sleeves, connecting rods, and synchronous pulleys, as well as a protective cover, a drive motor, and a synchronous belt. The two ends of the threaded rods are rotatably connected to the mounting plate, the inner circumference of the threaded sleeve is threadedly connected to the outer circumference of the threaded rod, and the threaded sleeve is slidably connected to the receiving groove with a limit. One end of the connecting rod passes through the slot and is inserted into the upper end of the threaded sleeve, and the other end of the connecting rod is inserted into the front end of the folding plate near the side of the pool.

[0011] The front end of the protective cover is fixedly connected to the side of the pool body. The drive motor is bolted to the outer wall of the protective cover. The output end of the drive motor is plugged into a set of synchronous pulleys. One end of the threaded rod passes through the mounting plate and is plugged into the side of the synchronous pulley away from the drive motor. The two sets of synchronous pulleys are connected by a synchronous belt drive.

[0012] Furthermore, a locking block is provided at the upper end of the folding plate on the side away from the pool body to restrict the movement of the folding plate by means of a limiting block.

[0013] Compared with existing technologies, it has the following beneficial effects:

[0014] This utility model provides an ecological filter for wastewater treatment. A drive mechanism, during heavy rain or other extreme weather, causes a folding plate to move horizontally, covering the upper part of the filter to prevent rainwater from entering. Simultaneously, nitrogen and other gases generated by microbial reactions within the filter are expelled through the pressure difference between the inside and outside of the filter, as well as by external wind, causing a non-powered wind cap to rotate. This effectively reduces the impact of extreme weather on the activity of the microbial community in the filter and prevents excessive nitrogen accumulation within the filter, thus ensuring the effective wastewater treatment of the ecological filter under adverse weather conditions.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 6 As shown, the present invention provides the following technical solution: a sewage treatment ecological filter, including a tank body 1, with an opening at the upper end of the tank body 1, and a shield 2 provided on the side of the opening of the tank body 1 to prevent rainwater from entering the filter. The shield 2 is unfolded by a drive mechanism 3 and covers the upper opening of the tank body 1.

[0024] The shield 2 includes two sets of folding plates 21, which are fixedly connected in the middle by a horizontal plate 22. A non-powered vent 23 is provided on the horizontal plate 22, extending to the lower part of the horizontal plate 22. The drive mechanism 3 drives the folding plates 21 to move horizontally along the transverse side of the pool body 1. The folding plates 21 are stretched by the drive to cover the upper end of the pool body 1. The horizontal plate 22 is displaced by the drive to the middle of the upper end of the pool body 1. The non-powered vent 23 rotates to discharge the gas reacted in the pool body 1.

[0025] See Figure 2The bottom wall of the pool body 1 is provided with evenly distributed pipes 11, and an array of aeration discs 12 are installed on the pipes 11. The pipes 11 pass through the side of the pool body 1 and are interconnected. The aeration discs 12 are interconnected with the pipes 11, and the gas in the pipes 11 is released into the water through the aeration discs 12 to perform aeration operation, thereby controlling the dissolved oxygen concentration in the pool body 1. The part of the pipes 11 that passes through the pool body 1 is provided with a waterproof seal. The pool body 1 itself is installed underground, and its side has an underground space for daily maintenance and equipment placement. The upper part of the pool body 1 is above ground.

[0026] See Figure 1 as well as Figure 2 A gas pump 13 is installed at one end of the pipe 11. The other end of the gas pump 13 is connected to an oxygen supply device or connected to the ground. The gas required for aeration operation is pumped through the pipe 11 to each aeration disc 12 by the gas pump 13.

[0027] See Figure 2 Fixed rods 14 are evenly inserted into the side wall of the pool body 1, and biofilm 15 is inserted into the lower part of the fixed rods 14. The fixed rods 14 are sliding insertion type, and the biofilm 15 can be lifted out of the pool body 1 as a whole by pulling the fixed rods 14, so as to facilitate the observation of the state of the biofilm 15 and the replacement of the biofilm 15.

[0028] It should be noted that the side wall of tank 1 is equipped with an inlet pipe for water intake and a drain pipe for water discharge. The inlet pipe is located at the upper end of the side of tank 1, through which the wastewater to be treated enters the interior of tank 1. The drain pipe is located at the lower end of the side of tank 1, through which the wastewater treated in the biological tank enters the next process. Both the inlet and drain pipes are equipped with solenoid valves and water pumps to control the water intake and discharge.

[0029] As another embodiment, such as Figures 2 to 6 As shown, the upper end of the pool body 1 has receiving grooves 16 on both sides, and mounting plates 17 are provided at both ends of the receiving grooves 16. The upper end of the pool body 1 is also fixedly connected to a limiting rail 18, and the cover plate 2 is slidably connected to the limiting rail. Among them, one end of the folding plate 21 is provided with a sliding block, and the other end is connected to the horizontal plate 22. Both the sliding block and the horizontal plate 22 are slidably connected to the limiting rail. The folding plate 21 is made of a corrugated deformable metal material, which allows the folding plate 21 to fold and unfold when subjected to force. Through the setting of the limiting rail, the folding plate 21 is limited during the shrinking and folding process, and the middle part will not come out or the shrinkage will be out of control.

[0030] See Figure 4 The lower end of the limiting track 18 has a through slot 181, and the upper inner wall of the limiting track 18 is welded and fixed with a limiting block 182.

[0031] See Figures 3 to 5The drive mechanism 3 includes two sets of threaded rods 31, threaded sleeves 32, connecting rods 33, and synchronous pulleys 34. It also includes a protective cover 35, a drive motor 36, and a synchronous belt 37. The two ends of the threaded rods 31 are rotatably connected to the mounting plate 17. The inner circumference of the threaded sleeve 32 is threadedly connected to the outer circumference of the threaded rod 31. The threaded sleeve 32 has a limited sliding connection with the receiving groove 16. One end of the connecting rod 33 passes through the slot 181 and is inserted into the upper end of the threaded sleeve 32. The other end of the connecting rod 33 is inserted into the front end of the folding plate 21 near the side of the pool body 1.

[0032] It should be noted that the threads of the two sets of threaded rods 31 are in the same direction. The sliding connection between the threaded sleeve 32 and the receiving groove 16 is limited so that the threaded sleeve 32 can only move in a horizontal linear direction and cannot rotate.

[0033] When the threaded rod 31 is driven to rotate, the threaded sleeve 32 connected to it is driven to move horizontally along the direction of the receiving groove 16, thereby driving the connecting rod 33 to move synchronously. The displacement of the connecting rod 33 simultaneously drives the folding plate 21 near the pool body 1 to move towards the pool body 1. The folding plate 21 then drives the horizontal plate 22 and the folding plate 21 away from the pool body 1 to move to the upper end of the pool body 1, thus shielding the pool body 1.

[0034] The front end of the protective cover 35 is fixedly connected to the side of the pool body 1. The drive motor 36 is bolted to the outer wall of the protective cover 35. The output end of the drive motor 36 is inserted into a set of synchronous pulleys 34. One end of the threaded rod 31 passes through the mounting plate 17 and is inserted into the side of the synchronous pulley 34 away from the drive motor 36. The two sets of synchronous pulleys 34 are connected by a synchronous belt 37.

[0035] The protective cover 35 is waterproof and has an opening door at the front for easy maintenance and replacement of its internal structure. The drive motor 36 is a waterproof motor, or it can be encased in a waterproof housing. The synchronous belt 37 is a trapezoidal synchronous transmission belt, and the synchronous pulley 34 has corresponding locking slots to ensure stable transmission of the synchronous belt 37 and prevent slippage. Accordingly, the synchronous pulley 34 and the synchronous belt 37 can be replaced by a chain drive.

[0036] Meanwhile, a rain sensor can be installed on the upper end of the horizontal plate 22, and the rain sensor can be electrically connected to the drive motor 36, so that the drive motor 36 can be automatically started by rain sensing in the event of heavy rain, or the operator can remotely start the drive motor 36 to carry out the operation in extreme weather.

[0037] When it is necessary to cover the pool body 1, the drive motor 36 is started, so that the output end of the drive motor 36 drives the synchronous pulley 34 to rotate. The rotation of a single set of synchronous pulleys 34 is transmitted through the synchronous belt 37 to achieve the synchronous rotation of two sets of synchronous pulleys 34, which in turn drives the threaded rod 31 to rotate synchronously in the same direction. The threaded sleeve 32 is driven by the threaded rod 31 to drive the cover plate 2 to move horizontally.

[0038] See Figure 6 A locking block 211 is provided at the upper end of the folding plate 21 on the side away from the pool body 1, so as to restrict the movement of the folding plate 21 by means of the limiting block 182. As the folding plate 21 moves towards the upper end of the pool body 1, the locking block 211 at the upper end of the rear folding plate 21 contacts the limiting block 182, so that the rear end of the folding plate 21 can no longer move. As the front folding plate 21 continues to move, it is pulled to extend. The threaded sleeve 32 drives the front folding plate 21 to continue to move to the other end of the pool body 1, completing the overall shielding of the upper end of the pool body 1. The non-powered vent 23 moves to the middle of the upper end of the pool body 1 and continuously discharges the lower gas.

[0039] When there is no need for shielding, the drive motor 36 rotates in the opposite direction, and the threaded sleeve 32 drives the front folding plate 21 to move in the opposite direction, and the folding plate 21 naturally retracts back to its initial state.

[0040] Working principle: When pool 1 needs to be covered, the drive motor 36 is started, which drives the synchronous pulley 34 to rotate. Through the transmission of the synchronous belt 37, the two sets of threaded rods 31 rotate synchronously in the same direction. This causes the threaded sleeve 32 to drive the cover plate 2 to move horizontally along the limit track. Through the limit block 182, the folding plate 21 extends, finally completely covering the upper part of pool 1. At the same time, the non-powered vent 23 moves to the middle of the upper part of pool 1, continuously venting the lower gas. When the covering is no longer needed, the drive motor 36 rotates in the opposite direction, and the threaded sleeve 32 drives the front folding plate 21 to move in the opposite direction. The folding plate 21 naturally retracts back to its initial state.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
