Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment equipment technology, and in particular to a high-efficiency sedimentation tank for wastewater treatment in slaughterhouses. Background Technology

[0002] Wastewater sedimentation tanks are commonly used facilities for wastewater treatment. They mainly rely on gravity to allow suspended impurities in the water to settle. When wastewater flows into the tank, the flow rate slows down, and heavier silt, organic debris, etc. will slowly sink to the bottom of the tank, while the clear water on the surface flows out for further treatment.

[0003] Sludge deposited at the bottom of wastewater sedimentation tanks is cleaned regularly to avoid affecting the sedimentation effect. To facilitate cleaning, scrapers are installed inside the sedimentation tank to forcefully remove the sediment. To prevent direct friction between the scrapers and the tank bottom, thus avoiding tank wear or scraper jamming, a certain gap is left between the scrapers and the tank bottom in wastewater sedimentation equipment. However, when treating slaughterhouse wastewater, which contains large amounts of grease, meat scraps, and hair, and whose sediment contains a lot of organic matter, these substances accumulate at the bottom of the tank. Due to microbial decomposition and temperature changes, they slowly clump together, and with the binding effect of grease, they easily harden and clump. Therefore, the gap between the scrapers and the tank bottom becomes a problem. Clumps of sediment get stuck in the gaps, accumulating more and more, not only affecting the normal operation of the scrapers but also creating cleaning dead zones at the bottom of the tank. These residual sediments ferment and smell, further polluting the water quality, reducing the effective volume of the sedimentation tank, lowering wastewater treatment efficiency, and increasing the difficulty of subsequent cleaning. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency sedimentation tank for slaughterhouse wastewater treatment, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A high-efficiency sedimentation tank for slaughterhouse wastewater treatment includes a sedimentation tank with a flocculation mechanism on one side. A motor is fixedly connected to the sedimentation tank near the flocculation mechanism. The flocculation mechanism and the motor are electrically connected to an external main controller via cables. A drive sprocket is fixedly connected to the output end of the motor. Multiple driven sprockets are rotatably connected inside the sedimentation tank, and two driven sprockets on the same side are connected by a transmission chain. One of the driven sprockets is also connected to the drive sprocket at the output end of the motor via a transmission chain. Multiple scrapers are fixedly connected between two transmission chains. Multiple guide seats are fixedly connected to the bottom of the scrapers. A shaft seat is movably connected to the inner side of the guide seat, and a pressure roller is movably connected between two shaft seats.

[0007] As a further preferred embodiment of this utility model, two guide rails are fixedly connected to the bottom of the sedimentation tank. The two guide rails at the bottom of the sedimentation tank enable the scraper to move in a guided manner when it rotates through two transmission chains, thereby making the scraper more stable when scraping the sediment at the bottom of the sedimentation tank.

[0008] As a further preferred embodiment of this utility model, one of the driven sprockets is a double sprocket structure. By setting one of the driven sprockets to a double sprocket structure, it can be connected to the driving sprocket at the output end of the motor, thereby driving the transmission chain to rotate.

[0009] As a further preferred embodiment of this utility model, an installation groove is provided on the inner side of the guide seat, and a spring plate is fixedly connected in the installation groove. The installation groove provides conditions for the installation of the shaft seat, while the spring plate can provide a downward pressing force for the shaft seat, ensuring that the pressure roller is always in contact with the bottom of the sedimentation tank.

[0010] As a further preferred embodiment of this utility model, the cross-section of the bearing seat is I-shaped, and the bearing seat is slidably connected in the mounting groove.

[0011] As a further preferred embodiment of this utility model, multiple grinding rings are fixedly connected to the outer side of the pressure roller. The longitudinal cross-section of the grinding rings is triangular. A rotating shaft is fixedly connected to the center position of both sides of the pressure roller. The rotating shaft is rotatably connected to the corresponding rotating shaft. When the two transmission chains drive the scraper to move at the bottom of the sedimentation tank to scrape off the material, the pressure roller can roll at the bottom of the sedimentation tank through the two guide seats. With the help of the multiple grinding rings on the outer side, the sediment at the bottom of the sedimentation tank is crushed, preventing some sediment from settling and caking at the bottom of the sedimentation tank. This facilitates cleaning by water flow and the pressure roller.

[0012] As a further preferred embodiment of this utility model, a toothed plate is also fixedly connected to the bottom of the scraper located between the two guide seats. The toothed blocks at the bottom of the toothed plate are inserted between the two grinding rings, and the toothed plate can clean the sediment stuck between the two grinding rings.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this invention, a pressure roller is set between multiple guide seats at the bottom of the scraper for guidance. Multiple grinding rings are set on the outside of the pressure roller. The multiple grinding rings on the outside of the pressure roller can work with the shaft seat and spring sheet to make the multiple grinding rings on the outside of the pressure roller tightly adhere to the bottom of the tank without leaving gaps. This crushes the clumps of sediment and makes it easy for the scraper to remove them, avoiding cleaning dead corners. At the same time, it reduces friction with the sedimentation tank body, reduces the problem of fermentation and odor, and maintains the effective volume of the tank body. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figures 1-5 As shown, the high-efficiency sedimentation tank for slaughterhouse wastewater treatment provided by this utility model includes a sedimentation tank 1. A flocculation mechanism 2 is provided on one side of the sedimentation tank 1. A motor 3 is fixedly connected to the sedimentation tank 1 near the flocculation mechanism 2. The flocculation mechanism 2 and the motor 3 are electrically connected to an external main controller via cables. A drive sprocket is also fixedly connected to the output end of the motor 3. Multiple driven sprockets 4 are rotatably connected inside the sedimentation tank 1. Two driven sprockets 4 on the same side are connected by a transmission chain 5. One of the driven sprockets 4 is also connected to the drive sprocket at the output end of the motor 3 via the transmission chain 5. Multiple scrapers 6 are fixedly connected between the two transmission chains 5. Multiple guide seats 7 are fixedly connected to the bottom of the scrapers 6. A shaft seat 8 is movably connected to the inner side of the guide seat 7. A pressure roller 9 is movably connected between the two shaft seats 8.

[0023] like Figures 1-2 As shown, two guide rails 10 are fixedly connected to the bottom of the sedimentation tank 1. The two guide rails 10 at the bottom of the sedimentation tank 1 enable the scraper 6 to move in a guided manner with the guide seat 7 when it rotates through the two transmission chains 5. This makes the scraper 6 more stable when scraping the sediment at the bottom of the sedimentation tank 1. One of the driven sprockets 4 is a double sprocket structure. By setting one of the driven sprockets 4 as a double sprocket structure, it can be connected to the drive sprocket at the output end of the motor 3 through the driven sprocket 4, thereby driving the transmission chain 5 to rotate.

[0024] like Figures 2-5 As shown, the guide seat 7 has an installation groove 11 on its inner side, and a spring plate 12 is fixedly connected in the installation groove 11. The installation groove 11 provides conditions for the installation of the shaft seat 8, while the spring plate 12 can provide a downward pressing force for the shaft seat 8, ensuring that the pressure roller 9 is always in contact with the bottom of the sedimentation tank 1. The shaft seat 8 has an I-shaped transverse cross section and is slidably connected in the installation groove 11. Multiple grinding rings 14 are fixedly connected to the outer side of the pressure roller 9. The longitudinal cross section of the grinding rings 14 is triangular. Rotating shafts 13 are fixedly connected to the center positions of both sides of the pressure roller 9. The rotating shafts 13 are rotatably connected in the corresponding rotating shafts 13. When the two When the drive chain 5 drives the scraper 6 to move at the bottom of the sedimentation tank 1 to scrape off the material, the pressure roller 9 can roll at the bottom of the sedimentation tank 1 through the two guide seats 7, and crush the sediment at the bottom of the sedimentation tank 1 with the help of multiple grinding rings 14 on the outside, preventing some sediment from settling and caking at the bottom of the sedimentation tank 1, which is convenient for cleaning by water flow and the pressure roller 9. The scraper 6 located between the two guide seats 7 is also fixedly connected to the bottom of the toothed plate 15. The toothed blocks at the bottom of the toothed plate 15 are inserted between the two grinding rings 14, and the toothed plate 15 can clean the sediment stuck between the two grinding rings 14.

[0025] It should be noted that this utility model is a high-efficiency sedimentation tank for slaughterhouse wastewater treatment. During wastewater treatment, the flocculation mechanism 2 first pre-treats the wastewater entering the sedimentation tank 1, causing suspended impurities to agglomerate into easily sedimentable particles, which are then fed into the sedimentation chamber within the sedimentation tank 1. Afterwards, the motor 3 starts, and its output drive sprocket drives the driven sprocket 4 to rotate via the transmission chain 5. The driven sprocket 4 on the same side then forms a cyclic transmission via the transmission chain 5. A transmission shaft is also fixedly connected between two of the driven sprockets 4, thereby driving the scraper 6 between the two transmission chains 5 to move. The guide rail 10 at the bottom of the sedimentation tank 1 and the guide seat 7 at the bottom of the scraper 6... In coordination, to ensure the stable movement of scraper 6, spring plates 12 are located in the mounting groove 11 inside guide seat 7, which apply downward pressure to shaft seat 8, keeping the pressure roller 9 connected to shaft seat 8 always close to the bottom of the tank. The longitudinal section of the grinding ring 14 on the outer side of the pressure roller 9 is triangular. When the pressure roller 9 rolls, it can crush the sediment that has clumped at the bottom of the tank and at the same time prevent the sediment from clumping at the bottom of the sedimentation tank 1. Meanwhile, the toothed plates 15 at the bottom of scraper 6 are inserted between the grinding rings 14, which can clean the impurities stuck in the gaps of the grinding rings 14 and prevent them from getting stuck. In this way, the crushed sediment is smoothly scraped off by scraper 6, solving the problem of cleaning dead corners in traditional equipment and improving the efficiency of sewage treatment.
