Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an anti-clogging slag removal bar screen. Background Technology

[0002] A bar screen is a solid-liquid separation device that can continuously remove impurities from fluids. It is widely used in urban sewage treatment, waterworks, power plant inlets, textiles, food processing, papermaking, leather and other industries. In sewage treatment, an anti-clogging bar screen is used to prevent clogging.

[0003] To address this, patent CN210286784U discloses a rotary bar screen, comprising a bar screen body, an installation frame fixedly connected to one end of the bar screen body, the upper end of the installation frame communicating with the outside, an installation hole opened on the end of the installation frame away from the bar screen body, a collection drawer slidably connected in the installation hole, and a scraping mechanism provided on the inner walls on both sides of the installation frame for scraping garbage off the bar screen body. By fixing the installation frame to one end of the bar screen body, the upper end of the installation frame communicating with the outside, and the collection drawer slidably connected in the installation frame, the bar screen body lifts the garbage into the collection drawer for collection, and the scraping mechanism scrapes the garbage off the bar screen body, thus facilitating the collection of garbage lifted from the bar screen body and making it easier for garbage to be scraped off the bar screen body.

[0004] While the rotary bar screen mentioned above facilitates the scraping of garbage off the bar screen itself, its inconvenience in conveying waste and preventing the accumulation of impurities makes it unsuitable for use. Utility Model Content

[0005] The purpose of this invention is to provide an anti-clogging slag discharge bar screen to solve the problem of inconvenient conveying of existing anti-clogging slag discharge bar screens.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an anti-clogging slag discharge bar screen, including a frame;

[0007] The frame is equipped with a slag removal structure inside, and a cleaning structure is provided on one side of the top of the frame;

[0008] A conveyor structure is provided on one side of the frame;

[0009] The conveying structure includes a base disposed on one side of the frame, a cylinder fixed to the top of the base, a cover plate fixed to one end of the cylinder, a spiral blade shaft disposed inside the cylinder, a drive motor mounted on the outer wall of the cylinder at one end of the spiral blade shaft, a feed hopper fixed to one side of the top of the cylinder, and a slag discharge port fixed to the bottom of the cylinder near the cover plate.

[0010] When using this device, the conveying structure facilitates the prevention of accumulation, thereby improving the applicability of the slag removal bar screen. The slag cleaning structure facilitates the interception of impurities, thereby improving the ease of use. The sweeping structure facilitates the prevention of clogging, thereby improving the stability of the slag removal bar screen during use.

[0011] Preferably, the slag removal structure includes a first drive roller, a screen body, a second drive roller, a drive motor, screen teeth, and a chain. The screen body is disposed inside the frame. The bottom of the screen body is penetrated by the first drive roller, and the top two sides of the screen body are penetrated by the second drive roller. Screen teeth are fixed on the outer sides of both ends of the first and second drive rollers. The top of the screen teeth is meshed with a chain. A drive motor is installed on the outer wall of the frame at one end of the second drive roller.

[0012] Preferably, both ends of the first drive roller extend into the interior of the frame and form a rotating structure with the frame, and both ends of the second drive roller extend into the interior of the frame and form a rotating structure with the frame. When the second drive roller is working inside the frame, it drives the chain to rotate through the grid teeth, the chain drives the grid body to move, and at the same time drives the first drive roller to rotate.

[0013] Preferably, the output end of the drive motor is fixedly connected to one end of the second drive roller, and both sides of the screen body are fixedly connected to one side of the chain. Under the action of the screen body, solid suspended matter and floating matter in the sewage can be intercepted and removed, allowing impurities to be discharged through one side of the top of the screen body, while the sewage flows to the next process through the gaps in the screen body.

[0014] Preferably, one end of the spiral blade extends into the interior of the cover plate and forms a rotating structure with the cover plate, while the other end extends into the exterior of the cylinder and is fixedly connected to the output end of the drive motor. When impurities enter the interior of the cylinder through the feed hopper, the cylinder reduces the diffusion of odors, and the spiral blade ensures that the impurities are evenly discharged through the slag discharge port, thereby preventing the accumulation of impurities.

[0015] Preferably, the cleaning structure includes a scraper, a cleaning roller, cleaning brushes, and a cleaning motor. The cleaning roller is located on one side of the top of the frame, and cleaning brushes are evenly fixed to the outer side of the cleaning roller. A scraper is provided on one side of each cleaning brush, and a cleaning motor is installed on the outer wall of the frame at one end of the cleaning roller. When the cleaning roller is working at the top of the frame, it drives the cleaning brushes to clean the grille body. Under the action of the cleaning brushes, impurities can be cleaned, preventing the grille body from becoming clogged.

[0016] Preferably, both sides of the scraper are fixedly connected to the inner wall of the frame, one side of the scraper abuts against one side of the cleaning brush, and one end of the cleaning roller extends to the outside of the frame and is fixedly connected to the output end of the cleaning motor. Under the action of the scraper, impurities on the outside of the cleaning brush can be scraped off.

[0017] The advantages of the anti-clogging slag discharge bar screen provided by this utility model are as follows:

[0018] By setting up a conveying structure, when impurities enter the interior of the cylinder through the feed hopper, the diffusion of odor is reduced under the action of the cylinder, and the impurities are evenly discharged through the slag discharge port under the action of the spiral blade shaft, thereby preventing the accumulation of impurities. This realizes the function of the device to prevent accumulation, thereby improving the applicability of the slag discharge bar screen in use.

[0019] By incorporating a slag removal structure, when the second drive roller is working inside the frame, it drives the chain to rotate via the grid teeth. The chain then moves the grid body and simultaneously rotates the first drive roller. Under the action of the grid body, it can intercept and remove solid suspended matter and floating matter in the sewage, allowing impurities to be discharged through one side of the top of the grid body. Meanwhile, the sewage flows to the next process through the gaps in the grid body. This device effectively intercepts impurities, thereby improving the convenience of using the slag removal grid machine.

[0020] With a cleaning structure, when the cleaning roller is working at the top of the frame, it drives the cleaning brush to clean the screen body. Under the action of the cleaning brush, impurities can be cleaned to prevent the screen body from clogging. Under the action of the scraper, impurities on the outside of the cleaning brush can be scraped off, realizing the anti-clogging function of the device and thus improving the stability of the slag discharge screen machine during use.
