Abstract
Description
Technical Field
[0001] This utility model belongs to the field of wastewater treatment technology, and more specifically, it relates to a self-cleaning sedimentation tank for industrial wastewater. Background Technology
[0002] Industrial wastewater treatment is an essential step in modern industrial construction. Due to the massive volume of wastewater generated by industry, wastewater treatment is a crucial task in reducing environmental pollution. Currently, industrial wastewater is treated using chemical and biological methods to extract heavy metals and harmful substances from the wastewater. After sedimentation and filtration, the wastewater is then discharged. A common sedimentation method involves natural sedimentation in a settling tank, followed by the discharge of the supernatant. This results in harmful solids settling at the bottom of the settling tank. However, large settling tanks have a large water storage capacity, and after long-term sedimentation, there is a significant amount of suspended solids, making them inconvenient to clean and transport.
[0003] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a self-cleaning sedimentation tank for industrial wastewater, in order to achieve a more practical purpose. Utility Model Content
[0004] To address the aforementioned technical problems, this utility model provides a self-cleaning sedimentation tank for industrial wastewater, which solves the problem that large sedimentation tanks have a large water storage capacity and a large amount of suspended solids after long-term sedimentation, making them inconvenient to clean and transport.
[0005] The purpose and effect of this utility model's self-cleaning sedimentation tank for industrial wastewater are achieved through the following specific technical means:
[0006] An industrial wastewater self-cleaning sedimentation tank includes a tank body with a downwardly recessed center forming an inner tank. The lower wall of the tank body is inclined around the inner tank to form a funnel surface. A collection bowl is installed inside the inner tank. A hanger is installed on the top of the tank body. A trolley on the hanger is connected to the collection bowl via a cable. A sludge removal structure is provided at the edge of the tank body.

[0008] Furthermore, a scraper is hinged to the bottom of the vertical rod, the direction of the scraper is offset from the direction pointing to the center of the pool, and the end of the scraper extends into the inner pool and is provided with a counterweight.
[0009] Furthermore, a worm gear is provided at the top of the vertical rod, and a worm that meshes with the worm gear is threaded through the connecting seat. One end of the worm passes through the connecting seat and is connected to the handle.
[0010] Furthermore, the connecting seat is L-shaped, with one end extending above the pool body and the other end extending to one side of the guide rail. A sliding claw is provided at the bottom of the connecting seat, and the sliding claw is slidably engaged on the guide rail. The motor is located on the side wall of the connecting seat, and the motor output shaft passes through the connecting seat and is connected to a bevel gear. A rack is provided on the outer periphery of the pool body below the guide rail, and the bevel gear meshes with the rack.

[0024] Example:
[0025] As attached Figure 1 To be continued Figure 5 As shown:
[0026] This utility model provides an industrial wastewater self-cleaning sedimentation tank, including a tank body 1. The tank body 1 realizes liquid inlet and drainage through a pipe (not shown). The center of the tank body 1 is recessed downward to form an inner tank 2. The low wall of the tank body 1 is inclined around the inner tank 2 to form a funnel surface. The funnel surface setting allows the solid waste settled at the bottom of the tank body to concentrate in the inner tank 2 after long-term sedimentation of wastewater.
[0027] The inner pool 2 is equipped with a collection bowl 8, and the top of the pool body 1 is equipped with a hanger 5. The trolley 6 on the hanger 5 is connected to the collection bowl 8 via a cable 7. When it is necessary to clean solid waste, the water in the pool body 1 is drained and the collection bowl 8 in the inner pool is lifted and transported by the trolley 6, which is more convenient and facilitates the cleaning of large sedimentation tanks.
[0028] The pool body 1 is equipped with a sludge removal structure at its edge to scrape off and clean the solid waste adhering to the inner wall of the pool body 1. The sludge removal structure includes a guide rail 3 on the outer periphery of the pool body 1, a connecting seat 10 slidably mounted on the guide rail 3, and the connecting seat 10 is driven by a motor 103 to move on the guide rail 3. A vertical rod 101 is inserted through the connecting seat 10 at a position extending inside the pool body 1, and a scraper 107 is mounted on the vertical rod 101. The scraper 107 abuts against the inner wall of the pool body 1. The motor 103 drives the connecting seat 10 to follow the guide rail 3 to make a circular motion around the edge of the pool body 1, and the scraper 107 can clean the surface of the inner wall of the pool body 1.
[0029] like Figure 3 As shown, the connecting seat 10 is L-shaped, with one end extending into the upper part of the pool body 1 and the other end extending to one side of the guide rail 3. A sliding claw 11 is provided at the bottom of the connecting seat 10, and the sliding claw 11 is slidably locked on the guide rail 3. The motor 103 is provided on the side wall of the connecting seat 10, and the output shaft of the motor 103 passes through the connecting seat 10 and is connected to the bevel gear 102. A rack 301 is provided on the outer periphery of the pool body 1 below the guide rail 3. The bevel gear 102 meshes with the rack 301. The rotation of the motor 103 causes the bevel gear 102 to rotate. The bevel gear 102, through the meshing rack 301, causes the connecting seat 10 to follow the guide rail 3 in a circular motion.
[0030] The bottom of the vertical rod 101 is hinged with a scraper 108. The direction of the scraper 108 is offset from the direction pointing to the center of the pool body 1. When the connecting seat 10 moves in a circle, it can also drive the scraper 108 to clean the funnel surface inside the pool body 1. Due to the offset direction of the scraper 108, the scraped solid waste can be guided into the inner pool 2. The end of the scraper 108 extends into the inner pool 2 and is provided with a counterweight 109. The setting of the counterweight 109 allows the scraper 108 to be in close contact with the bottom funnel surface of the pool body 1.
[0031] Among them, the vertical rod 101 is rotatable, such as Figure 2 As shown, a worm gear 104 is provided at the top of the vertical rod 101, and a worm 105 that meshes with the worm gear 104 is passed through the connecting seat 10. One end of the worm 105 passes through the connecting seat 10 and is connected to the handle 106. By rotating the handle 106, the angle of the scraper 107 on the vertical rod 101 can be adjusted, so that the side wall of the pool body 1 can be cleaned from light to heavy. At the same time, the offset angle of the scraper beam 108 relative to the center of the pool body 1 can be adjusted.
[0032] An observation platform 9 is set up next to the pool body 1. The observation platform 9 is used to observe the operation of the hanger 5 and the trolley 6. Piers 4 are set on the outside of the pool body 1 and on the observation platform 9. The feet of the hanger 5 are installed on the piers 4. The trolley 6 can transfer the collection bowl 8 between the pool body 1 and the observation platform 9 for processing. A central support 501 is set in the middle of the hanger 5 to increase the stability of the hanger 5 and avoid large deformation of the hanger 5 span.
[0033] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
