Description

Technical Field

[0001] This utility model relates to the field of sedimentation tank packing technology, specifically to a coagulant addition device for sedimentation tanks. Background Technology

[0002] In industry, the treatment of mercury-containing wastewater generally employs coagulation and sedimentation. Coagulants are added to the wastewater to disrupt the stability of colloids, causing colloids and fine suspended solids in the wastewater to aggregate into separable flocs. This concentrates harmful substances in the wastewater into sludge, purifying the water and allowing for the harmless disposal of the sludge. Currently, sedimentation tanks are typically used for wastewater settling, with coagulants then added by workers.

[0003] Various coagulant adding devices exist in the existing technology, but most of the existing adding devices are fixedly installed on one side of a specific sedimentation tank. When coagulant needs to be added to multiple sedimentation tanks or different locations, multiple adding devices are required, which results in high costs. Therefore, a mobile coagulant adding device was designed, which leads to the need for this sedimentation tank coagulant adding device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a coagulant addition device for sedimentation tanks, which solves the technical problems mentioned in the background section.

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.

[0015] Please see Figure 1 This utility model provides a technical solution: a coagulant addition device for sedimentation tanks, including a trolley 1, a drive rotation assembly installed on the upper end of the trolley 1, a coagulant addition mechanism installed on the upper end of the drive rotation assembly, the coagulant addition mechanism including a liquid discharge assembly, a drive liquid discharge assembly, and a coagulant placement assembly, the coagulant placement assembly including a second box 5, a first rectangular through hole opened on the upper wall of the second box 5, a sliding door 6 installed inside the first rectangular through hole, a first plate 7 installed on the inner side wall of the second box 5, a pair of frames 18 installed on the upper wall of the first plate 7, and a tank 19 movably placed on the pair of frames 18.

[0016] When adding coagulant, the tank 19 is filled with coagulant. After filling, the tank 19 is installed inside the second housing 5 by opening the sliding door 6 and fixing it with a pair of frames 18. Then, the first motor 4 inside the first housing 3 is started, and the rotation of the first motor 4 drives the second housing 5 to adjust the position of the nozzle 25. The trolley 1 can then be moved using the push rod 2 to different sedimentation tank positions. The second motor 9 is then started, and its drive end rotates the cam 10. Wheel 10 drives roller 12 to move second rod 11. At this time, the second rod 11 swings and resets through the reset effect of return spring 16 and the rotation of cam 10, thereby completing the movement of plug 22 inside cylinder 21. At this time, with the assistance of one-way valves on first pipe 20 and second pipe 24, the coagulant inside tank 19 is discharged into cylinder 21 through first pipe 20 and discharged through cylinder 21 through second pipe 24 and nozzle 25, thus completing the quantitative discharge of coagulant and enabling convenient addition of coagulant at different locations.

[0017] In this embodiment, the drive rotation assembly includes a first housing 3, which is mounted on the flatbed 1. A first motor 4 is installed inside the first housing 3, and the drive end of the first motor 4 is mounted on the lower wall of the second housing 5.

[0018] By activating the first motor 4 inside the first housing 3, the rotation of the drive end of the first motor 4 drives the second housing 5 to rotate, thus completing the position adjustment of the nozzle 25.

[0019] In this embodiment, the driving liquid dispensing assembly includes a first rod 8, a second rod 11 hinged to the side wall of the first rod 8, a first rectangular groove formed on the side wall of the second rod 11, a roller 12 installed inside the first rectangular groove, a second motor 9 installed inside the second housing 5, a cam 10 installed at the driving end of the second motor 9 and the cam 10 located on one side of the roller 12, and a pair of first fixing blocks 13 installed on the inner side wall of the second housing 5, with a [missing information - likely a device or mechanism] installed between the pair of first fixing blocks 13. A third rod 15 is fitted with a sleeve 14. A return spring 16 is installed between the sleeve 14 and the first fixing block 13 and is fitted onto the third rod 15. A second fixing block 17 is installed on the side wall of the sleeve 14. A sliding groove is formed on the side wall of the second fixing block 17. A slider is installed inside the sliding groove. The side wall of the slider is hinged to one end of the second rod 11. A fourth rod 23 is installed on the side wall of the second fixing block 17. One end of the fourth rod 23 is connected to the liquid outlet assembly.

[0020] The second motor 9 is started, and the cam 10 is driven to rotate through the drive end of the second motor 9. At this time, the cam 10 pushes the roller 12 to move the second rod 11. At this time, the second rod 11 swings and resets through the reset effect of the reset spring 16, thereby completing the movement of the plug 22 inside the cylinder 21. At this time, the coagulant inside the tank 19 is discharged into the cylinder 21 through the first pipe 20 and the second pipe 24 with the assistance of the one-way valves on the first pipe 20 and the second pipe 24, and then discharged through the cylinder 21 through the second pipe 24 and the nozzle 25.

[0021] In this embodiment, the liquid dispensing assembly includes a cylinder 21, which is mounted on the lower wall of the first plate 7. A plug 22 is placed inside the cylinder 21, and the plug 22 is mounted on the side wall of one end of the fourth rod 23. A second tube 24 and a first tube 20 are respectively mounted on one end of the cylinder 21. One end of the first tube 20 is movably mounted on the tank 19, and a nozzle 25 is mounted on one end of the second tube 24.

[0022] In this embodiment, a one-way valve is installed on both the first pipe body 20 and the second pipe body 24, and a push rod 2 is installed on the trolley 1.

[0023] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0024] Example: When adding coagulant, the tank 19 is filled with coagulant. After filling, the tank 19 is installed inside the second housing 5 by opening the sliding door 6 and fixing it with a pair of frames 18. Then, the first motor 4 inside the first housing 3 is started, and the rotation of the first motor 4 drives the second housing 5 to adjust the position of the nozzle 25. The push rod 2 can then push the trolley 1 to move it to different sedimentation tank positions. Finally, the second motor 9 is started, and the second motor 9 drives the cam 10 to rotate. When the cam 10 pushes the roller 12 to move the second rod 11, the second rod 11 can be swung back to its original position by the rotation of the cam 10 through the reset effect of the reset spring 16. This allows the plug 22 to move inside the cylinder 21. With the assistance of the one-way valves on the first pipe 20 and the second pipe 24, the coagulant inside the tank 19 can be discharged into the cylinder 21 through the first pipe 20 and then discharged through the cylinder 21 through the second pipe 24 and the nozzle 25, thus completing the quantitative discharge of the coagulant and enabling convenient addition of the coagulant at different locations.
