[0028] Specifically, first, the connecting part of the filter cartridge 3 and the feeding pipe 2 is accurately aligned, the central axes of the two are completely coincided, and the connecting part is tightly attached, after the alignment, the clamp one 6 and the clamp two 7 are carefully sleeved outside the connecting part of the filter cartridge 3 and the feeding pipe 2, the opening parts of the clamps are opposite, then, the fixing bolt 8 is passed through the bolt holes on the clamp one 6 and the clamp two 7, it is ensured that the fixing bolt 8 can smoothly pass through and perfectly match with the bolt holes, then, the nuts 9 are screwed on the two ends of the fixing bolt 8, the clamp one 6 and the clamp two 7 are gradually tightened, until the filter cartridge 3 and the feeding pipe 2 are firmly fixed together, after the installation and fixing work is completed, the coagulant is poured into the filter cartridge 3, the coagulant will first pass through the coarse filter screen 4 in the filter cartridge 3, the coarse filter screen 4 can preliminarily intercept the larger particle impurities in the coagulant, and plays the role of the first layer of filtration, then, the coagulant after the preliminary filtration will continue to downwardly pass through the fine filter screen 5, the fine filter screen 5 can further filter out the tiny impurities therein, so as to ensure that the coagulant entering the storage barrel 1 has high purity.
[0029] With reference to the accompanying drawings, the technical solutions in the embodiments of the present application will be clearly and completely described below, obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by the ordinary skilled in the art without creative labor are within the protection scope of the present application. Figure 1 and Figure 4The stirring assembly 10 includes a motor 101, which is fixedly installed on the upper side of the storage tank 1. The output end of the motor 101 is fixedly connected to a stirring shaft 102. An upper stirring blade 103 is fixedly connected to the outer side of the stirring shaft 102, and a lower anchor blade 104 is fixedly connected to the lower side of the stirring shaft 102. Both the upper stirring blade 103 and the lower anchor blade 104 are rotatably connected inside the storage tank 1.
[0030] Specifically, the filtered coagulant smoothly enters the storage tank 1. At this time, the motor 101 is started, and the output end of the motor 101 drives the stirring shaft 102 to start rotating, causing the upper stirring blade 103 and the lower anchor blade 104 to rotate. The upper stirring blade 103 is mainly responsible for stirring the solution in the upper part of the storage tank 1. Stirring promotes the full diffusion and mixing of the coagulant in the solution. At the same time, the lower anchor blade 104 can effectively prevent the coagulant at the bottom of the storage tank 1 from settling, so that the solution in the entire storage tank 1 can be uniformly mixed.
[0031] Reference Figure 1 and Figure 5 The control component 13 includes a liquid level sensor 132, which is installed on the inner wall of the metering tank 12. A solenoid valve 131 is fixedly installed on the outside of the outlet pipe 11. A drain pipe 133 is fixedly connected to the lower side of the metering tank 12. An observation window 14 is fixedly installed on both the storage tank 1 and the metering tank 12. A control panel 15 is fixedly installed on the front side of the storage tank 1. The control panel 15 is electrically connected to the motor 101, the solenoid valve 131 and the liquid level sensor 132.
[0032] Specifically, after the coagulant solution in storage tank 1 is mixed evenly, the solution flows into metering tank 12 through outlet pipe 11. Liquid level sensor 132 monitors the liquid level in metering tank 12 in real time. When the liquid level reaches the preset value, liquid level sensor 132 transmits a signal to control panel 15. After receiving the signal, control panel 15 controls the solenoid valve 131 installed on the outside of outlet pipe 11 to close, thereby stopping the liquid from entering metering tank 12 and realizing the quantitative storage of coagulant solution. When coagulant needs to be added, the operator only needs to open the valve of drain pipe 133 on the lower side of metering tank 12, and the quantitative coagulant solution will be discharged from drain pipe 133 for use in tap water production. In addition, observation windows 14 are installed on both storage tank 1 and metering tank 12. The operator can conveniently observe the internal liquid level and solution status through observation windows 14 to keep track of the device's operating status.
[0033] Working principle: When using this device, first align the connection between the filter cylinder 3 and the feed pipe 2. Then, put clamp 6 and clamp 7 on the outside of the connection. Next, pass the fixing bolt 8 through the bolt hole of the clamp and screw the nuts 9 on both ends. Rotate the nuts 9 to tighten the clamp and fix the filter cylinder 3 and the feed pipe 2. Then, the coagulant enters through the feed pipe 2. It first passes through the coarse filter screen 4 in the filter cylinder 3 to initially intercept larger particles of impurities. Then, it passes through the fine filter screen 5 below to further filter out small impurities, ensuring the purity of the coagulant entering the storage tank 1. The filtered coagulant enters the storage tank 1. Start the motor 101 on the upper side of the storage tank 1. The output end of the motor 101 drives the stirring shaft 102 to rotate. The upper stirring blade 103 on the outside of the stirring shaft 102 is responsible for stirring the upper solution in the storage tank 1, promoting the diffusion and mixing of the coagulant in the solution. The lower anchor blade 104 at the bottom prevents the bottom coagulant from settling, so that the solution in the entire storage tank 1 is uniformly mixed.
[0034] The uniformly mixed coagulant solution flows into the metering tank 12 through the outlet pipe 11. The liquid level sensor 132 on the inner wall of the metering tank 12 monitors the liquid level in real time. When the liquid level reaches the set value, the solenoid valve 131 on the outside of the outlet pipe 11 is closed through the control panel 15 to stop the liquid inflow and achieve metering. When it is necessary to add the solution, the valve of the drain pipe 133 on the lower side of the metering tank 12 is opened, and the metered coagulant solution is discharged for tap water production. The observation window 14 on the storage tank 1 and the metering tank 12 allows the operator to observe the internal liquid level and solution status.
[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
