Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an interception device for wastewater treatment. Background Technology

[0002] Large particle debris interception devices used in wastewater treatment, commonly known as bar screens, are physical filtration devices installed at the wastewater inlet. Their core function is to intercept and remove large-sized solid floating objects and suspended debris, such as branches, plastic bags, bottles, fabric, and food scraps, before the wastewater enters the treatment system. They typically consist of a set of parallel metal bars (coarse bar screens) or screens (fine bar screens). As wastewater flows through, large particles are trapped on the bar screen surface, thus protecting subsequent pumps, pipes, and treatment units from blockage or damage. It is an essential pretreatment step in the wastewater treatment process and is widely used in municipal wastewater treatment plants, pumping stations, and industrial wastewater treatment facilities.

[0003] Currently, traditional wastewater treatment interception devices mostly use fixed bar screens or static screens, requiring periodic shutdowns and manual cleaning of trapped solid debris. This not only involves high operational intensity and maintenance costs but also interrupts the wastewater treatment process, affecting overall efficiency. While some mechanical cleaning devices possess certain automatic scraping functions, they still suffer from incomplete cleaning, large space requirements, and complex structures that are difficult to maintain. They struggle to achieve a synergistic effect of efficient interception and rapid self-cleaning under continuous operation, and are particularly prone to clogging when treating wastewater with high impurity content and high flow rates, resulting in poor reliability.

[0004] Therefore, we propose an interception device for wastewater treatment. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an interception device for wastewater treatment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a sewage treatment interception device, comprising two mounting side plates, one side of the outer surface of each of the two mounting side plates being fixedly connected to a first bearing seat extending to the other side, an electric shaft being installed between the two first bearing seats, and four mounting seats being uniformly fixedly connected to the outer surface of the electric shaft, one end of each of the four mounting seats being provided with a T-slot, and one side of the T-slot extending to the side wall of the mounting seat, and each of the four mounting seats being detachably fixed with a limit plate on the side wall;

[0007] Each of the four T-slots is fitted with a C-type interceptor assembly for limiting and insertion;

[0008] Each of the two mounting side plates has a through hole on one side of its outer surface, extending to the other side. An electric scraper is installed between the two mounting side plates, and the electric scraper matches the through hole and the C-type interception assembly.

[0009] Each of the mounting side plates is fixedly connected to a waste discharge groove on the side away from the other mounting side plate, and the waste discharge groove corresponds to the adjacent through hole.

[0010] Furthermore, the electric shaft includes a geared motor, which is fixedly mounted on the surface of the seat of the adjacent first bearing housing. The drive end of the geared motor is fixedly connected to the main shaft, and the inner rings of the bearings built into the two first bearing housings are fixedly sleeved on the outer surface of the main shaft. The mounting base is fixedly connected to the main shaft. This structure provides stable and powerful rotational power, ensuring that the four C-type interception components can withstand sewage impact and debris load when switching.

[0011] Furthermore, each of the four limiting plates is fixed to the adjacent mounting base by two bolts. This connection method is simple in structure and easy to install and remove. The limiting plate can be removed simply by loosening the bolts.

[0012] Furthermore, all four C-type interception components include T-shaped strips, and the T-shaped strips are inserted into adjacent T-shaped slots for limiting. One end of the T-shaped strip is fixedly connected to a mounting bracket, and a C-shaped grille is fixedly connected to one side of the outer surface of the mounting bracket. The two sides of the C-shaped grille are respectively attached to the adjacent mounting side plates. The insertion and cooperation between the T-shaped strips and the T-shaped slots realizes the positioning and installation of the components.

[0013] Furthermore, the integrated design of the T-shaped strip and the mounting bracket, along with the one-piece molding process, greatly enhances the structural strength and overall rigidity of the entire C-shaped interception assembly, making it less prone to deformation or damage under repeated sewage flushing and scraper cleaning.

[0014] Furthermore, the electric scraper includes two second bearing seats, which are fixedly connected to adjacent mounting side plates. A drive motor is fixedly connected to the surface of a single second bearing seat. A screw is fixedly connected to the drive end of the drive motor. The inner rings of the bearings built into the two second bearing seats are fixedly sleeved on the outer surface of the screw. The scraper body is threaded onto the outer surface of the screw, and the scraper body matches the through hole and C-shaped grid. This design accurately converts the rotational motion of the motor into the linear motion of the scraper body.

[0015] Furthermore, the two second bearing seats are jointly and fixedly connected to a guide rod, and the scraper body is slidably sleeved on the outer surface of the guide rod. The guide rod provides reliable auxiliary support and guidance for the movement of the scraper body.

[0016] The beneficial effects of this utility model are:

[0017] 1. In use, this utility model uses an electric shaft to drive four evenly distributed C-shaped interception components to rotate and switch. When a single screen is blocked, it can be automatically moved to the cleaning station and the clean screen can be activated simultaneously for continuous filtration, ensuring the continuous and efficient operation of sewage treatment. At the same time, combined with the electric scraper and waste discharge mechanism at the top, it can automatically scrape off and discharge the intercepted solid debris, significantly reducing maintenance intensity and manual cleaning costs, and improving the automation and reliability of the system.

[0018] 2. In use, the T-slot, limiting plate, mounting base and electric shaft of this utility model can facilitate the replacement of the C-type interception component, thereby improving the replacement efficiency and effect. Attached Figure Description

[0025] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1-3As shown, a wastewater treatment interception device is disclosed, comprising two mounting side plates 1. A first bearing seat 6, extending through to the other side, is fixedly connected to one side of the outer surface of each mounting side plate 1. An electric shaft is mounted between the two first bearing seats 6. Four mounting bases 5 are uniformly fixedly connected to the outer surface of the electric shaft. The electric shaft includes a geared motor 7, which is fixedly mounted on the surface of the seat of an adjacent first bearing seat 6. A main shaft 3 is fixedly connected to the drive end of the geared motor 7. The inner rings of the bearings built into the two first bearing seats 6 are fixedly fitted onto the outer surface of the main shaft 3. The mounting bases 5 are fixedly connected to the main shaft 3. The geared motor 7 is an NMRV040-20-S6-P1 type worm gear reducer motor. Contact rubber sealing rings are fixedly connected to both sides of the two first bearing seats 6. The rubber sealing rings are sealed and fitted onto the outer surface of the main shaft 3, effectively preventing wastewater and impurities from entering the bearing interior.

[0027] Each of the four mounting bases 5 has a T-slot 17 at one end, and one side of the T-slot 17 extends to the side wall of the mounting base 5. Each of the four mounting bases 5 is located on the side wall and can be detachably fixed with a limiting plate 16. Each of the four limiting plates 16 is fixed to the adjacent mounting base 5 by two bolts.

[0028] Each of the four T-slots 17 has a C-shaped interception component inserted into it. Each of the four C-shaped interception components includes a T-shaped strip 15, and the T-shaped strip 15 is inserted into the adjacent T-slot 17. One end of the T-shaped strip 15 is fixedly connected to a mounting bracket 4. A C-shaped grille 10 is fixedly connected to one side of the outer surface of the mounting bracket 4, and the two sides of the C-shaped grille 10 are respectively attached to the adjacent mounting side plate 1. The T-shaped strip 15 and the mounting bracket 4 are designed as an integral unit.

[0029] Each of the two mounting side plates 1 has a through hole 8 extending to the other side on one side of its outer surface. An electric scraper is installed between the two mounting side plates 1, and the electric scraper matches the through hole 8 and the C-type interception assembly. The electric scraper includes two second bearing seats 11, and the second bearing seats 11 are fixedly connected to the adjacent mounting side plate 1. A drive motor 12 is fixedly connected to the surface of the seat of each second bearing seat 11. The drive motor 12 is a 57HS09 type two-phase hybrid stepper motor. A screw 13 is fixedly connected to the drive end of the drive motor 12, and the inner rings of the bearings built into the two second bearing seats 11 are fixedly sleeved on the outer surface of the screw 13. Contact rubber bushings are provided on both sides of the two second bearing seats 11. A sealing ring is fitted onto the outer surface of the screw 13. A scraper body 9 is threaded onto the outer surface of the screw 13, and the scraper body 9 matches the through hole 8 and the C-shaped grille 10. The two second bearing seats 11 are jointly and fixedly connected to a guide rod 14, and the scraper body 9 is slidably fitted onto the outer surface of the guide rod 14. In actual use, two retractable flexible protective covers, commonly known as "screw screw protective covers" or "dust covers," can be installed on the screw 13. One end of each protective cover is fixed to the scraper body 9 (through an additional mounting plate or clamp), and the other end is fixed to the seats of the two second bearing seats 11. When the scraper body 9 moves, the protective covers extend and retract synchronously. This completely encloses the screw 13, thoroughly isolating it from the external environment (dust, moisture, and entangled materials).

[0030] A waste discharge trough 2 is fixedly connected to the side of a single mounting side plate 1 away from the other mounting side plate 1, and the waste discharge trough 2 corresponds to the adjacent through hole 8. The setting of the waste discharge trough 2 is conducive to the discharge of impurities.

[0031] I. Interception and Filtering Phase:

[0032] The device is installed in a sewage channel, with sewage flowing in from one side and out from the other.

[0033] In the initial state, one of the four C-shaped interception components is in a vertically downward working position, with its C-shaped grille 10 submerged in the sewage.

[0034] When sewage flows through the C-type screen 10, the solid suspended matter, garbage and other debris carried in the water are effectively intercepted by the screen and attached to the screen surface, while the filtered clean water continues to flow through the gaps in the screen, thus achieving solid-liquid separation in sewage treatment.

[0035] II. Switching and Scraping Cleaning Phase:

[0036] As debris accumulates, the filtration efficiency of the C-type grille 10 decreases, and water flow becomes obstructed.

[0037] At this time, the electric shaft starts (driven by the geared motor 7 to rotate the main shaft 3), which drives the four evenly distributed mounting seats 5 and the C-type interception components fixed thereto to rotate 90 degrees together.

[0038] The C-shaped interceptor component, which was originally in the working position and covered with debris, was moved to the middle position; while a previously cleaned and purified C-shaped interceptor component was rotated to the working position, seamlessly taking over to continue the interception and filtration work, ensuring the continuity of wastewater treatment.

[0039] The C-shaped interceptor assembly, now rotated to the top and laden with debris, has its concave side (C-shaped opening) facing upwards, directly opposite the electric scraper and through-hole 8.

[0040] The electric scraper is started (driven by the drive motor 12 to rotate the screw 13), which drives the scraper body 9 to move horizontally along the guide rod 14.

[0041] The scraper body 9 is embedded in the groove of the C-shaped grid 10, scraping away all the intercepted debris attached to its surface from the grid.

[0042] The scraped debris is discharged through the through hole 8 on the other side mounting plate 1 and falls into the pre-set waste discharge trough 2 below, and is finally discharged by the waste discharge trough 2 to complete the automatic cleaning (a collection device or frame can be preset for collection).

[0043] III. Cyclic Work:

[0044] After cleaning, the electric scraper returns to its original position.

[0045] When the working grille becomes clogged again, the electric shaft actuates again, repeating the above rotation switching and cleaning process. The four C-type interception components work in turn, forming a "work-wait-clean-standby" cycle.

[0046] IV. Replacement Operation:

[0047] When it is necessary to replace the corresponding C-shaped grille 10, after one end of the C-shaped grille 10 reaches the top, unscrew the bolts on the corresponding limiting plate 16, then remove the limiting plate 16, then pull the C-shaped interception assembly out of the T-shaped groove 17, then insert the new C-shaped interception assembly, and then fix the limiting plate 16 again.

[0048] It should be noted that, in actual use, an existing controller can be added. The controller is electrically connected to the geared motor 7 and the drive motor 12 to facilitate the control of the overall operation. The specific data analysis and processing involved to further realize the control function are methods that can be implemented by those skilled in the art based on common knowledge. These methods are not within the scope of this solution. The above description is only to illustrate the beneficial effects that can be achieved by this hardware structure improvement in conjunction with common knowledge.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
