Description

Technical Field

[0001] This utility model relates to the field of grit chamber technology, specifically a grit chamber for industrial wastewater treatment that is easy to clean. Background Technology

[0002] Sewage inevitably mixes with mud and sand during migration, flow and collection. If the sand in the sewage is not removed by pre-sedimentation and separation, it will affect the operation of subsequent treatment equipment. Most importantly, it will wear down pumps and ducts, block pipe networks, and interfere with or even destroy the biochemical treatment process.

[0003] After a period of use, sedimentation tanks need to be cleaned at the bottom. Existing technology involves using a movable cleaning plate to clean the mud and sand to one side of the sedimentation tank, and then using a sludge pump to extract the mud and sand. However, since the mud and sand accumulate at the bottom of the sedimentation tank and have a large mass, the cleaning plate cannot effectively clean the mud and sand.

[0004] For example, a grit chamber for wastewater treatment (publication number: CN216566305U) uses a moving plate that continuously moves along the inner wall of the chamber to scrape away sludge from the bottom and inner wall and push it to the extraction pipes on both sides. This allows for rapid sludge removal without moving the sludge pump, greatly improving cleaning speed and efficiency. However, in actual use, due to the large mass of the sludge, the moving plate experiences significant resistance during movement, which can easily overload the motor and damage it. This results in the aforementioned problem of not being able to effectively remove sludge, reducing the practicality of the device. Therefore, we need to propose a grit chamber for industrial wastewater treatment that is easy to clean. Utility Model Content

[0005] The purpose of this invention is to provide a grit chamber for industrial wastewater treatment that is easy to clean. It can clean sludge and sand in layers, avoid excessive resistance when the scraper moves, which could damage the motor, and improve the practicality of the device, thereby solving the problems mentioned in the background art.

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.

[0026] Please see Figure 1-3 This utility model provides a technical solution: a grit chamber for easy cleaning in industrial wastewater treatment, including a grit chamber 1, a support frame 4, a lifting mechanism 8 and a moving mechanism 9, etc.

[0027] The sedimentation tank 1 has an inlet pipe 2 and an outlet pipe 3 fixedly connected to its two ends, with the inlet pipe 2 located above the outlet pipe 3. A support frame 4 is movably installed on the top of the sedimentation tank 1. A lifting plate 5 is installed inside the support frame 4 and can be raised and lowered. Two sets of connecting rods 6 are symmetrically fixedly connected to the bottom of the lifting plate 5. Scrapers 7 are fixedly connected to the bottom of the two sets of connecting rods 6. The two sides of the scrapers 7 are respectively attached to the inner walls of the sedimentation tank 1. A lifting mechanism 8 is set on the support frame 4 to drive the lifting plate 5 to rise and fall. A moving mechanism 9 is set on the top of the sedimentation tank 1 to drive the support frame 4 to move.

[0028] In this embodiment, sewage enters the sedimentation tank 1 through the inlet pipe 2 for sedimentation and is discharged through the outlet pipe 3. When it is necessary to clean the mud and sand at the bottom of the sedimentation tank 1, the height of the lifting plate 5 can be adjusted by the lifting mechanism 8. The lifting plate 5 drives the scraper 7 to rise and fall through two sets of connecting rods 6, and then drives the support frame 4 to move through the moving mechanism 9, so that the scraper 7 can move. The scraper 7 is used to clean the upper layer of mud and sand. Then the scraper 7 is lowered and this step is repeated until the mud and sand are cleaned. The mud and sand can be cleaned in layers, avoiding excessive resistance when the scraper moves, which may damage the motor and improve the practicality of the device.

[0029] The lifting mechanism 8 includes a first threaded rod 81, a first drive motor 82, a U-shaped frame 83, and two sets of auxiliary blocks 84. The U-shaped frame 83 is fixedly installed on the inner top of the support frame 4. The bottom end of the first threaded rod 81 is rotatably installed on the inner bottom of the U-shaped frame 83. The top end of the first threaded rod 81 passes through the support frame 4 and is fixedly connected to the first drive motor 82. The lifting plate 5 is threadedly connected to the outer wall of the first threaded rod 81.

[0030] In this embodiment, the output end of the first drive motor 82 rotates, which drives the first threaded rod 81 connected to it to rotate, so that the lifting plate 5 can be raised and lowered. The lifting plate 5 can drive the scraper 7 to be raised and lowered through two sets of connecting rods 6.

[0031] Both sides of the U-shaped frame 83 are provided with clearance slots that are compatible with the lifting plate 5. The lifting plate 5 can be lifted and installed inside the two sets of clearance slots.

[0032] In this embodiment, the first threaded rod 81 is supported by the U-shaped frame 83, and the two sets of clearance grooves provide conditions for the lifting plate 5 to rise and fall, and can limit the lifting plate 5 to prevent the lifting plate 5 from rotating when the first threaded rod 81 rotates.

[0033] Auxiliary slots are provided on both sides of the inner wall of the support frame 4. Two sets of auxiliary blocks 84 are slidably installed inside the two sets of auxiliary slots, and the bottom of the two sets of auxiliary blocks 84 are fixedly connected to the lifting plate 5.

[0034] In this embodiment, when the lifting plate 5 is raised or lowered, it will drive the two sets of auxiliary blocks 84 to slide inside the two sets of auxiliary slots respectively, which helps to improve the stability of the lifting plate 5.

[0035] The moving mechanism 9 includes a second threaded rod 91, a second drive motor 92, and a limiting rod 93. The second threaded rod 91 is rotatably installed on one side of the top of the sedimentation tank 1. One end of the second threaded rod 91 is fixedly connected to the second drive motor 92, and one side of the support frame 4 is threadedly connected to the second threaded rod 91.

[0036] In this embodiment, the output end of the second drive motor 92 drives the second threaded rod 91 connected to it to rotate, so that the support frame 4 moves, thereby driving the scraper 7 to move.

[0037] The limiting rod 93 is fixedly installed on the other side of the top of the sedimentation tank 1, and the other side of the support frame 4 is slidably connected to the limiting rod 93;

[0038] In this embodiment, the limiting rod 93 can limit the support frame 4, so that the support frame 4 can move when the second threaded rod 91 rotates;

[0039] The top of the sedimentation tank 1 is symmetrically provided with two sets of sliding grooves, and sliders 10 are slidably installed inside the two sets of sliding grooves. The tops of the two sets of sliders 10 are fixedly connected to the support frame 4.

[0040] When the support frame 4 moves, it will drive the two sets of sliders 10 to move inside the two sets of sliding grooves respectively. The two sets of sliders 10 can support the support frame 4, which helps to improve the stability of the support frame 4.

[0041] Both sides of the sedimentation tank 1 are fixedly connected to extraction pipes 11. One end of each extraction pipe 11 is fixedly connected to a three-way pipe 12. The other end of the three-way pipe 12 is fixedly connected to an extraction main pipe 13. One end of the extraction main pipe 13 is fixedly connected to a sludge pump 14.

[0042] In this embodiment, the sludge pump 14 can extract the sludge and sand inside the sedimentation tank 1 by cooperating with the extraction main pipe, the three-way pipe 12 and the two sets of extraction pipes 11.

[0043] Working principle: When this utility model is in use, sewage enters the interior of the sedimentation tank 1 through the inlet pipe 2 for sedimentation and is discharged through the outlet pipe 3. When it is necessary to clean the mud and sand at the bottom of the sedimentation tank 1, the height of the lifting plate 5 can be adjusted by the lifting mechanism 8. The lifting plate 5 drives the scraper 7 to rise and fall through two sets of connecting rods 6, and then drives the support frame 4 to move through the moving mechanism 9, so that the scraper 7 can move. The scraper 7 is used to clean the upper layer of mud and sand. Then the scraper 7 is lowered and this step is repeated until the mud and sand are cleaned. The mud and sand can be cleaned in layers, avoiding excessive resistance when the scraper moves, which may damage the motor and improve the practicality of the device.
