Abstract
Description
Technical Field
[0001] This utility model relates to the field of coal chemical technology, specifically a sedimentation tank for coal chemical wastewater. Background Technology
[0002] In the coal chemical industry, wastewater treatment is a crucial step. Wastewater sedimentation tanks, as an important component of the wastewater treatment system, primarily function to remove suspended solids and impurities from wastewater through sedimentation, ensuring the smooth operation of subsequent treatment processes.
[0003] However, after long-term operation, traditional wastewater sedimentation tanks tend to accumulate a large amount of impurities and dirt on their internal sidewalls. This impurity and dirt not only affects the sedimentation effect but can also corrode and damage the sedimentation tank, thus shortening its service life. Furthermore, traditional wastewater sedimentation tanks have shortcomings in lid securing; the connection between the lid and the sedimentation tank is often not tight enough, easily leading to wastewater leakage and odor emission, causing environmental pollution. Additionally, the disassembly and installation of the lid is relatively complex, making maintenance and repair inconvenient. Therefore, we propose a coal chemical wastewater sedimentation tank. Utility Model Content
[0004] The purpose of this utility model is to provide a sedimentation tank for coal chemical wastewater to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A coal chemical wastewater sedimentation tank includes a wastewater sedimentation tank with a cover inserted into it. A first pulley is rotatably mounted on the left side inside the cover, and a second pulley is rotatably mounted on the right side inside the cover. The second pulley is connected to the first pulley via a transmission belt. An installation shaft is rotatably mounted on the bottom of the transmission belt via an installation block. A rack is also provided on the inner wall of the cover. A gear is connected to the installation shaft via a key, and the gear meshes with the rack. A brush is provided at the bottom of the installation shaft, and the brush contacts the side wall of the wastewater sedimentation tank.
[0007] As a further embodiment of this utility model: an installation cavity is provided on the side wall of the wastewater sedimentation tank, a sliding plate is slidably arranged in the installation cavity, an insertion rod is provided on the side wall of the sliding plate, and an insertion hole is provided on the tank cover for use with the insertion rod.
[0008] As a further improvement of this utility model: the slide plate is also provided with a support rod, which penetrates the side wall of the wastewater sedimentation tank and is slidably connected to the wastewater sedimentation tank.
[0009] As a further improvement of this utility model, a handle is provided at the outer end of the support rod.
[0010] As a further improvement of this utility model: a return spring is sleeved on the outer side of the support rod, one end of the return spring is connected to the slide plate, and the other end of the return spring is connected to the inner wall of the mounting cavity.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] 1. When the drive belt drives the mounting shaft to move, the meshing of the gear and rack causes the mounting shaft to rotate simultaneously, thereby driving the bottom brush to clean the side wall of the wastewater sedimentation tank. This realizes the automatic movement and rotation of the brush, which not only improves cleaning efficiency but also reduces the intensity of manual labor and ensures the long-term stable operation of the sedimentation tank.
[0013] 2. With the cooperation of the insertion rod and the insertion hole, and through the structure of the sliding plate, support rod and return spring, the sedimentation tank can achieve convenient fixing and tight connection of the tank cover. This not only improves the airtightness of the sedimentation tank and effectively prevents wastewater leakage and odor emission, but also makes the disassembly and installation of the tank cover simpler and more convenient, and facilitates maintenance and repair.

[0020] Example
[0021] Please see Figures 1-4 In this embodiment of the utility model, a coal chemical wastewater sedimentation tank includes a wastewater sedimentation tank 1. A tank cover 2 is inserted into the wastewater sedimentation tank 1. A first pulley 3 is rotatably mounted on the left side inside the tank cover 2, and a second pulley 4 is rotatably mounted on the right side inside the tank cover 2. The second pulley 4 is connected to the first pulley 3 via a transmission belt 5. An installation shaft 6 is rotatably mounted on the bottom of the transmission belt 5 via an installation block. Under the action of the first pulley 3, the second pulley 4, and the transmission belt 5, the installation shaft 6 can be moved. A rack 8 is also provided on the inner wall of the tank cover 2. A gear 7 is connected to the installation shaft 6 via a key. The gear 7 meshes with the rack 8. When the transmission belt 5 drives the installation shaft 6 to move, the gear 7... Under the action of the rack 8, the mounting shaft 6 will rotate. The bottom of the mounting shaft 6 is equipped with a brush 9, which contacts the side wall of the wastewater sedimentation tank 1. When the brush 9 rotates, it can clean the inside of the wastewater sedimentation tank 1, thereby reducing the occurrence of excessive impurities inside the wastewater sedimentation tank 1 that affect the subsequent use efficiency. To a certain extent, it ensures the use efficiency of the wastewater sedimentation tank 1. The top of the tank cover 2 is also equipped with a servo motor 10. The power output shaft of the servo motor 10 is connected to the rotating shaft of the second pulley 4 through a coupling. At this time, the servo motor 10 can drive the brush 9 to move, thereby causing the brush 9 to rotate under the action of the gear 7 and the rack 8, thus better cleaning the inside of the wastewater sedimentation tank 1.
[0022] The wastewater sedimentation tank 1 is also provided with an installation cavity 11 on its side wall. A sliding plate 12 is slidably arranged in the installation cavity 11. An insertion rod 13 is provided on the side wall of the sliding plate 12. The tank cover 2 is provided with an insertion hole that cooperates with the insertion rod 13. At this time, under the action of the insertion rod 13 and the insertion hole, the tank cover 2 can be installed and fixed, thereby ensuring the airtightness of the wastewater sedimentation tank 1 during use, and thus ensuring the efficiency of the wastewater sedimentation tank 1.
[0023] A support rod 14 is also provided on the sliding plate 12. The support rod 14 passes through the side wall of the wastewater sedimentation tank 1 and is slidably connected to the wastewater sedimentation tank 1. Under the action of the support rod 14, the insertion rod 13 can be moved. A handle 15 is provided at the outer end of the support rod 14. The support rod 14 can be moved by the handle 15. A return spring 16 is sleeved on the outer side of the support rod 14. One end of the return spring 16 is connected to the sliding plate 12, and the other end of the return spring 16 is connected to the inner wall of the mounting cavity 11. Under the action of the return spring 16, the connection quality between the insertion rod 13 and the insertion hole is guaranteed, thereby ensuring the efficiency of the wastewater sedimentation tank 1.
[0024] In actual use, when the servo motor 10 is started, its power output shaft drives the second pulley 4 to rotate via a coupling. The second pulley 4 is connected to the first pulley 3 via a transmission belt 5, so the first pulley 3 also rotates. A mounting shaft 6 is rotatably mounted on the bottom of the transmission belt 5 via a mounting block. Under the combined action of the first pulley 3, the second pulley 4, and the transmission belt 5, the mounting shaft 6 begins to move. A gear 7 is keyed to the mounting shaft 6, and a rack 8 meshes with the gear 7 on the inner wall of the cover 2. When the mounting shaft 6 moves, the gear 7 meshes with the rack 8, causing the mounting shaft 6 to rotate. A brush 9 is installed at the bottom of the mounting shaft 6. The brush 9 contacts the side wall of the wastewater sedimentation tank 1. Therefore, when the mounting shaft 6 rotates, the brush 9 also rotates to clean the inside of the wastewater sedimentation tank 1. A sliding plate 12 is slidably installed in the mounting cavity 11 on the side wall of the wastewater sedimentation tank 1. The insertion rod 13 on the side wall of the sliding plate 12 is used to cooperate with the insertion hole on the tank cover 2 to fix the tank cover 2. The handle 15 can drive the support rod 14 and the sliding plate 12 to move, thereby controlling the insertion and removal of the insertion rod 13. The return spring 16 ensures the connection quality between the insertion rod 13 and the insertion hole, ensuring the airtightness and efficiency of the wastewater sedimentation tank 1.
