[0002] Coagulation and sedimentation water purification technology is a physical and chemical method widely used in the field of water treatment. It adds coagulants to water to condense suspended particles and colloidal substances in the water into larger particles, and then separates them from the water through sedimentation, thereby achieving the purpose of purifying water quality. This technology is widely used in industrial wastewater treatment, domestic sewage treatment, drinking water purification and other fields due to its simple operation and relatively low cost.

[0003] However, the existing coagulation sedimentation water purification device has some shortcomings:

[0004] Limited treatment efficiency: Traditional coagulation and sedimentation devices often rely on the natural sedimentation process, which has a slow sedimentation rate and low treatment efficiency, especially when treating water bodies containing a large amount of suspended matter and colloidal substances, the sedimentation effect is often unsatisfactory.

[0005] Low degree of automation: Many traditional devices require manual intervention to clean and discharge sediment, which not only increases the workload of operators but also reduces the continuity and stability of the treatment process.

If the specific posture changes, the directional indication will also change accordingly.

[0049] In addition, "multiple" means more than two. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0050] Please refer to the instruction manual Figure 1-Figure 6 The utility model provides a coagulation sedimentation water purification device, which mainly includes a sedimentation box 1, a filter press plate 2, a filter press plate downward driving mechanism 3 and a sediment extrusion and pushing mechanism 4. The sedimentation box 1 is the main structure of the whole device, and its internal space is used for the coagulation sedimentation process.

[0051] Installation and movement of filter press plate 2:

[0052] The filter press plate 2 is installed in the sedimentation box 1 by sliding and clamping up and down, and can move up and down. It is located at the top of the sedimentation box 1 at the initial stage of sedimentation. After the sedimentation process is completed, it can move downward to filter the sediment. The filter press plate pressing drive mechanism 3 is installed inside the sedimentation box 1, and is used to drive the filter press plate 2 to press downward to achieve compaction of the sediment.

[0053] Structure and function of sediment extrusion and ejection mechanism 4:

[0054] The sediment extrusion and pushing mechanism 4 comprises a pushing cylinder 41 installed at the bottom center of the right side of the sedimentation box 1 and an extrusion and pushing plate 42 connected to the pushing end of the pushing cylinder 41. The extrusion and pushing plate 42 is distributed at the bottom of the sedimentation box 1, and its front and rear ends are slidably fitted on the front and rear side walls of the sedimentation box 1, and is used to push the compacted sediment out of the sedimentation box 1 after the liquid above the filter press plate 2 is discharged.

[0055] Discharge of sediment:

[0056] A discharge box door 13 is installed at the bottom box wall on the left side of the sedimentation box 1, which is used in conjunction with the sediment extrusion and pushing mechanism 4. When the sediment is pushed out by the extrusion pushing plate 42, it can be discharged from the sedimentation box 1 through the discharge box door 13, which is convenient for operators to perform maintenance and cleaning.

[0057] Detailed structure of filter plate pressing drive mechanism 3:

[0058] The filter plate pressing mechanism 3 comprises a lifting drive screw 32 that is rotatably connected to the top center of the sedimentation tank 1, a screw sleeve 33 that is threadedly sleeved on the lifting drive screw 32, and a rotary drive mechanism 31 that is installed on the top of the outer side of the sedimentation tank 1 to drive the lifting drive screw 32 to rotate. The screw sleeve 33 is installed at the center of the filter plate 2. The lifting drive screw 32 is rotated by the drive of the rotary drive mechanism 31, driving the screw sleeve 33 and the filter plate 2 to move up and down.

[0059] Detailed structure of the rotary drive mechanism 31:

[0060] The rotary drive mechanism 31 includes a drive motor 311 installed on the top right side of the sedimentation tank 1, a drive sprocket 312 connected to the output end of the drive motor 311, a drive shaft 315 connected to the top of the lifting drive screw 32, a transmission sprocket 313 connected to the top of the drive shaft 315, and a transmission chain 314 sleeved between the transmission sprocket 313 and the drive sprocket 312. The transmission ratio between the drive sprocket 312 and the transmission sprocket 313 is set to 2:1 to ensure the stable rotation of the lifting drive screw 32.

[0061] Setting of guiding structure:

[0062] Vertically distributed guide convex teeth 5 are arranged at the four corner ends of the sedimentation box 1, and guide grooves 21 matched with the four guide convex teeth 5 are arranged at the four corner ends of the filter press plate 2 to ensure the stability and accuracy of the filter press plate 2 during the up and down movement.

[0063] Liquid inlet and outlet settings:

[0064] A liquid inlet valve pipe 11 is provided near the upper end of the front of the sedimentation tank 1 for introducing the liquid to be treated. A liquid discharge valve pipe 12 is also provided on the front of the sedimentation tank 1. One end of the inner side of the liquid discharge valve pipe 12 is located at the bottom height of the filter press plate 2, and is used to discharge the liquid after the coagulation and sedimentation treatment without discharging the sediment.

[0065] How it works

[0066] Liquid inlet stage:

[0067] The liquid inlet valve pipe 11 is opened to introduce the liquid to be treated into the interior of the sedimentation tank 1 .

[0068] Coagulation and sedimentation stage:

[0069] After adding the mixed additive, the liquid undergoes a coagulation and sedimentation process in the sedimentation tank 1, and the suspended matter and impurities gradually settle to the bottom of the tank.

[0070] Filter pressing stage:

[0071] After the coagulation and sedimentation is completed, the rotary drive mechanism 31 is started, and the drive motor 311 drives the lifting drive screw 32 to rotate through the drive sprocket 312, the drive chain belt 314 and the drive sprocket 313.

[0072] The rotation of the lifting drive screw 32 causes the screw sleeve 33 and the filter press plate 2 to move downward from the top of the sedimentation box 1.

[0073] The filter press plate 2 presses the sediment downwards through the filter press plate downward driving mechanism 3 to compact the sediment until it stops at a height that fits the top surface of the extrusion and pushing plate 42 .

[0074] Liquid discharge stage:

[0075] The liquid above the compacted sediment is discharged from the sedimentation tank 1 through the liquid discharge valve pipe 12, and the discharged liquid does not contain sediment at this time.

[0076] Sediment push-out stage:

[0077] After the liquid is discharged, the pushing cylinder 41 is started to push the compacted sediment from the bottom of the sedimentation box 1 from right to left by squeezing the pushing plate 42 .

[0078] Sediment discharge stage:

[0079] Open the discharge box door 13 and the sediment is discharged from the sedimentation box 1.
