[0025] Example 1 See also Figures 1 to 5 The present invention provides a standardized retractable multi-stage sedimentation tank, comprising a primary sedimentation tank 1, a secondary sedimentation tank 2, and a tertiary sedimentation tank 3 which are sequentially connected end to end, and a channel 4 is arranged between the primary sedimentation tank 1 and the secondary sedimentation tank 2, and between the secondary sedimentation tank 2 and the tertiary sedimentation tank 3; A connecting lock 5 is fixedly set at the four corners of the secondary sedimentation tank 2 adjacent to the primary sedimentation tank 1 and the tertiary sedimentation tank 3, and a limiting ring 6 is set at the four corners of the primary sedimentation tank 1 and the tertiary sedimentation tank 3 adjacent to the secondary sedimentation tank 2. The primary sedimentation tank 1 and the tertiary sedimentation tank 3 are connected to the secondary sedimentation tank 2 through the limiting ring 6 and the connecting lock 5.

[0026] First, the primary sedimentation tank 1 and the secondary sedimentation tank 2 are assembled, and the primary sedimentation tank 1 is moved to a position corresponding to the secondary sedimentation tank 2, so that the limiting ring 6 on the primary sedimentation tank 1 is aligned with the connecting locks 5 at the four corners of the secondary sedimentation tank 2, and the limiting ring 6 is inserted into the connecting lock 5 to connect the two firmly, ensuring that the connection parts are tight without looseness or excessive gaps, etc., to ensure that the subsequent water flow can pass normally through the channel 4 between the two; According to the same method, the secondary sedimentation tank 2 and the tertiary sedimentation tank 3 are spliced ​​together, thereby completing the main splicing work of the entire multi-stage sedimentation tank.

[0027] The first-stage sedimentation tank 1, the second-stage sedimentation tank 2 and the third-stage sedimentation tank 3 each include two rectangular frames 7 arranged opposite to each other, wherein two corners of the upper end of one of the frames 7 are respectively rotated to set a cross beam 8, and two corners of the lower end of the other frame 7 are respectively rotated to set a cross beam 8, and the cross beam 8 is detachably connected to the opposite frame 7; A plurality of telescopic frames 9 are arranged between the two frames 7, and an adjacent telescopic frame 9 and a frame 7, and two adjacent telescopic frames 9 are connected via a scissor unit 10; A water hose 11 is arranged between an adjacent telescopic frame 9 and the frame 7 and between two adjacent telescopic frames 9; A compartment plate 12 is fixedly disposed on each frame 7 of the primary sedimentation tank 1 , the secondary sedimentation tank 2 and the tertiary sedimentation tank 3 .

[0028] First, pull apart the two frames 7 of the primary sedimentation tank 1, rotate the crossbeam 8 to a horizontal position so that it is aligned with the corresponding installation position on the relative frame 7, and then use detachable connecting parts such as tightening bolts to firmly connect the crossbeam 8 to the relative frame 7, thereby building the frame 7 structure of the primary sedimentation tank 1.

[0029] The water hose 11 is a long strip-shaped component used to connect adjacent telescopic frames 9 and frames 7 or two adjacent telescopic frames 9; in terms of material, the water hose 11 may be made of rubber, plastic or other materials with good corrosion resistance and flexibility, because it needs to be in contact with sewage for a long time, and can maintain good sealing and integrity during the expansion and deformation process of the sedimentation tank; the water hose 11 works together with the compartment plate 12 to maintain the sedimentation partitions inside each sedimentation tank.

[0030] It enables the sewage in each compartment to settle in a relatively independent space, prevents the sewage at different sedimentation stages from mixing, and enables larger particles of suspended solids to settle better, providing a good foundation for the subsequent fine sedimentation in the secondary sedimentation tank 2 and the tertiary sedimentation tank 3.

[0031] The scissor-type forklift unit 10 includes two connecting rods rotatably connected to each other, the middle parts of the two connecting rods are rotatably connected to each other, the upper ends of the connecting rods are rotatably connected to the telescopic frame 9 or the frame 7, and the lower ends of the connecting rods are slidably connected to the telescopic frame 9 or the frame 7; The telescopic keel is U-shaped, and a roller is rotatably arranged at the lower end of the two vertical parts of the telescopic keel, and the roller rolls on one of the cross beams 8.

[0032] Each telescopic frame 9 has a slider at each end of the opening, and the slider slides on the upper crossbeam 8; The multiple scissor units 10 work together with the telescopic skeleton 9 and the frame 7 to form a stable and flexible structural system, which provides basic support for the expansion and folding of the sedimentation tank, ensuring that the entire sedimentation tank remains stable in different expansion and contraction states and can withstand the weight and force of sewage and various internal components.

[0033] A channel 4 for fluid movement is respectively provided on a compartment plate 12 adjacent to the primary sedimentation tank 1, the tertiary sedimentation tank 3 and the secondary sedimentation tank 2; A channel 4 for fluid movement is respectively provided on the two compartment plates 12 of the secondary sedimentation tank 2, and the primary sedimentation tank 1, the secondary sedimentation tank 2 and the tertiary sedimentation tank 3 are connected through the channel 4; The projections of the channel 4 between the primary sedimentation tank 1 and the secondary sedimentation tank 2 and the channel 4 between the secondary sedimentation tank 2 and the tertiary sedimentation tank 3 in the vertical plane are staggered.

[0034] Through the arrangement of the channels 4 on the compartment plates 12 of each level of the sedimentation tank and the design of the staggered projections of the channels 4, the entire multi-level sedimentation tank forms a tortuous but orderly water flow path. When the sewage flows in such a path, the flow rate is effectively controlled. More suspended matter will settle down each time it passes through a sedimentation tank 1, thereby achieving gradual and fine purification of the sewage. This design avoids the possible rapid, linear short-flow of sewage between the sedimentation tanks at each level, allowing the sewage to stay in each sedimentation tank for a sufficient time, making full use of the sedimentation space and conditions of each sedimentation tank, maximizing the sewage treatment capacity and sedimentation effect of the entire multi-stage sedimentation tank, and ensuring that the final discharged water meets the corresponding water quality requirements.

[0035] Sealing gaskets are respectively arranged at the passage 4 between the primary sedimentation tank 1 and the secondary sedimentation tank 2 and the passage 4 between the secondary sedimentation tank 2 and the tertiary sedimentation tank 3 .

[0036] During the operation of the multi-stage sedimentation tank, sewage flows through channel 4 between each level of sedimentation tank; the sealing gasket can tightly fill the tiny gaps between channel 4 and between channel 4 and the structural components of the sedimentation tank, forming an effective sealing barrier, ensuring that sewage can only flow from the primary sedimentation tank 1 through channel 4 into the secondary sedimentation tank 2, and then from the secondary sedimentation tank 2 through channel 4 into the tertiary sedimentation tank 3 according to the designed path, without leaking to other parts of the sedimentation tank or the external environment.

[0037] The connecting lock 5 includes a lock seat 13 fixedly arranged on the frame 7, an opening is arranged on one side of the lock seat 13, a lock hook 14 is rotatably arranged in the lock seat 13, a hook portion of the lock hook 14 moves in the opening, and a ratchet 15 is fixedly arranged on one end of the lock hook 14 away from the hook portion; A swing arm 16 is rotatably disposed in the lock seat 13 , a ratchet 17 is fixedly disposed at the movable end of the swing arm 16 , and a spring is disposed between the swing arm 16 and the lock seat 13 .

[0038] The operator manually operates the lock hook 14, rotates the lock hook 14 so that the hook part rotates from the opening of the lock seat 13 to the inside of the lock seat 13, and then inserts the limit ring 6 into the opening of the lock seat 13, and then rotates the lock hook 14 in the opposite direction so that the hook part rotates back and firmly hooks the limit ring 6. At this time, the pawl 17 of the swing arm 16 meshes with the ratchet 15. Under the action of the spring elastic force, the swing arm 16 drives the pawl 17 to maintain a close contact state with the ratchet 15. The cooperation between the pawl 17 and the ratchet 15 plays a role in preventing the pawl 17 from falling off. Even if the sedimentation tank is subjected to external force vibration, water flow impact, etc., the lock hook 14 is difficult to rotate in the opposite direction to loosen the limit ring 6 due to accident, thereby ensuring the stability of the connection between the two sedimentation tanks.

[0039] A support rod 18 is rotatably disposed on one of the side walls of the opening of the lock seat 13, and a movable end of the support rod 18 abuts against a hook portion of the lock hook 14; A torsion spring is arranged between the support rod 18 and the lock seat 13 .

[0040] A tension spring is arranged between the lock hook 14 and the lock seat 13; The lock hook 14 and the swing arm 16 are respectively provided with a pulling portion.

[0041] When the support rod 18 is located in the open end of the lock seat 13, it abuts against the hook portion of the lock hook 14. At this time, there is no need for an operator to operate the lock hook 14, and the casing can open the lock hook 14. When the limit ring 6 is inserted into the opening of the lock seat 13, the limit ring 6 first squeezes the support rod 18, and then the support rod 18 separates from the hook portion of the lock hook 14. As the limit ring 6 continues to be inserted, the lock hook 14 continues to rotate into the opening of the lock seat 13 under the action of the tension spring, so that the hook portion firmly hooks the limit ring 6. At this time, the pawl 17 of the swing arm 16 is meshed with the ratchet 15. Under the action of the spring force, the swing arm 16 will drive the pawl 17 to maintain a close contact state with the ratchet 15.

[0042] Thereby, the primary sedimentation tank 1 or the tertiary sedimentation tank 3 is preliminarily connected with the secondary sedimentation tank 2 at this connection point, and the stability and accuracy of the hooking operation are enhanced.

[0043] When the present invention is used, the primary sedimentation tank 1 and the secondary sedimentation tank 2 are firstly spliced, and the primary sedimentation tank 1 is moved to a position corresponding to the secondary sedimentation tank 2, so that the limiting ring 6 on the primary sedimentation tank 1 is aligned with the connecting locks 5 at the four corners of the secondary sedimentation tank 2, and the limiting ring 6 is inserted into the connecting lock 5 to connect the two firmly, ensuring that the connection parts are tight without looseness or excessive gaps, etc., so as to ensure that the subsequent water flow can pass normally through the channel 4 between the two; According to the same method, the secondary sedimentation tank 2 and the tertiary sedimentation tank 3 are spliced ​​together, thereby completing the main splicing work of the entire multi-stage sedimentation tank.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
