When the clips are fully engaged in the grooves, they are flush with the bar screen. At this point, the moving mechanism drives the scraper to move, bringing it into contact with the bar screen. Driven by the lifting mechanism, the scraper rises and scrapes away solid impurities from the bar screen surface, achieving cleaning.

Description

Technical Field

[0001] This utility model relates to the field of bar screen cleaning technology, specifically a bar screen surface cleaning device for sewage treatment. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. During the wastewater treatment process, the wastewater needs to be initially treated by passing through a screen. The screen can intercept solid impurities in the wastewater and facilitate subsequent treatment by the equipment.

[0003] In the prior art, Chinese Patent Publication No. CN222173306U discloses a surface cleaning device for fine screens in sewage treatment. By driving a water pump, water from inside the water tank can be delivered to a hose, which then delivers the water to a water pipe. The water pipe delivers the water to the cavity of the scraper, where it sprays out from the bottom of the cavity, thus rinsing the fine screen. Starting a rotary motor drives a lead screw to rotate, and the lead screw is threadedly connected to an outer moving block, causing the moving block to move back and forth when the lead screw rotates. The hose ensures that the movement of the moving block does not affect the movement of the pump and does not hinder its operation. Activating an electric push rod moves the strip plate up and down, and the scraper moves accordingly, allowing the device to control the scraper to clean the fine screen.

[0004] However, due to the structure of the bar screen, some solid impurities intercepted by the bar screen will get stuck in the bar grooves, resulting in incomplete cleaning when the scraper is used for cleaning. To address this, those skilled in the art have proposed a bar screen surface cleaning device for sewage treatment to solve the problems mentioned in the background. Utility Model Content

[0005] The purpose of this invention is to provide a surface cleaning device for a bar screen used in wastewater treatment, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A wastewater treatment screen surface cleaning device includes a movable plate and further includes:

[0008] A connecting arm is connected to a fixing plate, and several equally spaced locking strips are installed on the fixing plate;

[0009] A connecting frame, inside which a lifting mechanism is installed, and the lifting mechanism is connected to a scraper;

[0010] The moving mechanism is set on the movable plate. There are two moving mechanisms, which are symmetrically arranged on the movable plate. The two moving mechanisms are respectively connected to the connecting arm and the connecting frame.

[0011] As a further embodiment of this utility model: the moving mechanism includes two symmetrically distributed slide grooves on the movable plate, a slider is slidably disposed in the slide groove, the two sliders are respectively connected to the connecting arm and the connecting frame, a first threaded rod is rotatably disposed in the slide groove and threadedly connected to the slider, and a first motor connected to the first threaded rod is installed at the end of the movable plate.

[0012] As a further embodiment of this utility model: the lifting mechanism includes a second threaded rod rotatably disposed within the connecting frame, a second motor connected to the second threaded rod is installed on the top of the connecting frame, the second threaded rod is threadedly connected to a lifting block that fits against the inner wall of the connecting frame, and the lifting block is connected to a scraper through a mounting bracket.

[0013] As a further improvement of this utility model, the scraper is provided with several through holes.

[0014] As a further improvement of this utility model: side plates are installed on both sides of the mounting frame, and several equally spaced nozzles are installed on the side plates.

[0015] As a further improvement of this utility model: the movable plate is connected to a cylinder, and the cylinder is connected to a connecting plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model moves the movable plate to the top of the grid that needs to be cleaned, and aligns several clips on the fixed plate with the slots of the grid. Then, driven by the moving mechanism, the clips on the fixed plate are engaged in the slots of the grid, thereby pushing out the fixed impurities stuck in the slots of the grid. When the clips are fully engaged in the slots of the grid, the clips are flush with the grid. At this time, the scraper is driven to move by the moving mechanism, so that the scraper contacts the grid. Then, driven by the lifting mechanism, the scraper rises and scrapes off the solid impurities on the surface of the grid, thus achieving cleaning. This allows for thorough cleaning of fixed garbage accumulated at the grid, avoiding the situation where some solid garbage gets stuck in the slots of the grid and cannot be cleaned by the scraper. The effect is better. Attached Figure Description

[0021] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0022] Please see Figures 1-3 A wastewater treatment screen surface cleaning device includes a movable plate 1, and further includes:

[0023] Connecting arm 6, connecting arm 6 is connected to fixing plate 7, fixing plate 7 is equipped with several equally spaced clips 8;

[0024] Connecting frame 9, a lifting mechanism is provided inside the connecting frame 9, and a scraper 14 is connected to the lifting mechanism;

[0025] The moving mechanism is set on the movable plate 1. There are two moving mechanisms, which are symmetrically arranged on the movable plate 1. The two moving mechanisms are respectively connected to the connecting arm 6 and the connecting frame 9.

[0026] By moving the movable plate 1 to the top of the grating to be cleaned, and aligning the several clips 8 on the fixed plate 7 with the grooves of the grating, the clips 8 on the fixed plate 7 are then driven by the moving mechanism to engage with the grooves of the grating, thereby pushing out the fixed impurities stuck in the grooves of the grating. When the clips 8 are fully engaged with the grooves of the grating, they are flush with the grating. At this point, the scraper 14 is moved by the moving mechanism, making it contact the grating. Then, driven by the lifting mechanism, the scraper 14 rises and scrapes off the solid impurities on the surface of the grating, thus achieving cleaning. This allows for thorough cleaning of the fixed garbage accumulated at the grating, preventing some solid garbage from getting stuck in the grooves of the grating and making it impossible for the scraper 14 to clean it. The effect is better.

[0027] In one embodiment, the moving mechanism includes two symmetrically distributed slide grooves 2 on the movable plate 1. A slider 3 is slidably disposed in the slide groove 2. The two sliders 3 are respectively connected to the connecting arm 6 and the connecting frame 9. A first threaded rod 4 that is threadedly connected to the slider 3 is rotatably disposed in the slide groove 2. A first motor 5 that is connected to the first threaded rod 4 is installed at the end of the movable plate 1.

[0028] When it is necessary to adjust the position of the connecting arm 6 or the connecting frame 9 on the movable plate 1, the first motor 5 corresponding to the connecting arm 6 or the connecting frame 9 can be started. The first motor 5 will drive the first threaded rod 4 to rotate and drive the slider 3 to move along the slide groove 2, thereby adjusting the distance between the clip 8 or scraper 14 on the fixed plate 7 and the grid.

[0029] In one embodiment, the lifting mechanism includes a second threaded rod 11 rotatably disposed within the connecting frame 9, a second motor 12 connected to the second threaded rod 11 is mounted on the top of the connecting frame 9, the second threaded rod 11 is threadedly connected to a lifting block 10 that fits against the inner wall of the connecting frame 9, and the lifting block 10 is connected to a scraper 14 via a mounting bracket 13.

[0030] By activating the second motor 12, the second motor 12 drives the second threaded rod 11 to rotate and drives the lifting block 10 to rise, thereby causing the scraper 14 to move from the bottom to the top of the grid, so that the scraper 14 can clean solid impurities on the grid.

[0031] In one embodiment, the scraper 14 is provided with a plurality of through holes 15.

[0032] The through hole 15 allows for easy drainage of solid impurities cleaned by the scraper 14.

[0033] In one embodiment, side plates 16 are installed on both sides of the mounting bracket 13, and a plurality of equally spaced nozzles 17 are installed on the side plates 16.

[0034] The nozzle 17 is connected to an external water tank. Water is delivered to the nozzle 17 through a water pump and water pipes inside the water tank. The nozzle 17 can be used to clean the grille.

[0035] In one embodiment, the movable plate 1 is connected to a cylinder 18, which is connected to an air source and a connecting plate 19.

[0036] In use, the device is moved by connecting the connecting plate 19 to the mobile device, and the height of the movable plate 1 is adjusted by the cylinder 18.

[0037] This invention moves the movable plate 1 to the top of the grid that needs cleaning, aligning several locking strips 8 on the fixed plate 7 with the grooves of the grid. Then, driven by the moving mechanism, the locking strips 8 on the fixed plate 7 are engaged in the grooves of the grid, thereby pushing out the fixed impurities stuck in the grooves of the grid. When the locking strips 8 are fully engaged in the grooves of the grid, they are flush with the grid. At this point, the moving mechanism drives the scraper 14 to move, so that the scraper 14 contacts the grid. Then, driven by the lifting mechanism, the scraper 14 rises and scrapes off the solid impurities on the surface of the grid, thus achieving cleaning. This allows for thorough cleaning of fixed garbage accumulated at the grid, preventing some solid garbage from getting stuck in the grooves of the grid and preventing the scraper 14 from cleaning it. The effect is better.
