[0002] Polyaluminum chloride solution is an inorganic polymeric coagulant solution widely used in water treatment, chemical industry and other fields. Its core advantage lies in its high efficiency in flocculation, which can quickly adsorb suspended particles in water and form large flocs to achieve solid-liquid separation.

[0003] Currently, polyaluminum chloride solutions produced by chemical companies will spontaneously flocculate during storage in sedimentation tanks due to the deterioration of colloidal stability. Regular cleaning is required; otherwise, a large amount will accumulate at the bottom of the finished product tank, affecting the quality and selling price of polyaluminum chloride and reducing product profits.

[0004] Currently, the cleaning of polyaluminum chloride (PAC) finished product tanks is usually done manually. This manual cleaning method is inefficient, resource-intensive, and increases production costs. Furthermore, when workers enter the PAC tanks for cleaning, the flocculated material inside can easily cause slips and falls, posing a safety hazard. Utility Model Content

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0027] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this application.

[0028] An automatic flocculant removal device, referring to Figure 1 It includes an inlet water pipe 1, a finished product tank 2, a recycling pipe 3, an automatic backwash bag filter 4, a flushing pipe 5, and a controller (not shown in the diagram).

[0029] The inlet pipe 1 is connected to the finished product tank 2. The inlet pipe 1 can be connected to any position in the finished product tank 2, but the preferred connection position is the upper part of the finished product tank 2, which can reduce the possibility of material backflow into the finished product tank 2. Automatic control valve 6, centrifugal pump 7, and automatic control valve 8 are sequentially installed on the inlet pipe 1 along the material flow direction. Automatic control valve 6, centrifugal pump 7, and automatic control valve 8 are all electrically connected to the controller.

[0030] The finished product tank 2 is equipped with an online concentration meter 9 and an online turbidity meter 10, both of which are electrically connected to the controller. The online concentration meter 9 can be installed in the middle or upper part of the finished product tank 2. It is used to test the concentration of the polyaluminum chloride solution in the finished product tank 2. When the concentration of polyaluminum chloride in the finished product tank 2 drops to a certain value, the inlet water pipe 1 is closed, stopping the addition of water to the finished product tank 2. The online turbidity meter 10 is located at the lower part of the finished product tank 2. It is used to test the content of flocculants in the finished product tank 2. When the flocculants have settled to a certain extent, the recovery pipe 3 is opened, drawing the material from the finished product tank 2 to the automatic backwash bag filter 4 for treatment.

[0031] The inlet of the recovery pipeline 3 is connected to the bottom of the finished product tank 2, which facilitates the extraction of flocculants from the finished product tank 2 for filtration. The outlet of the recovery pipeline 3 is connected to the inlet of the automatic backwash bag filter 4, and the outlet of the automatic backwash bag filter 4 is connected to the finished product tank 2. Preferably, the outlet of the automatic backwash bag filter 4 is located above the finished product tank 2. A homogenizing pump 11 and an automatic control valve 12 are sequentially installed on the recovery pipeline 3 along the material flow direction. Both the homogenizing pump 11 and the automatic control valve 12 are electrically connected to the controller.

[0032] The discharge end of the automatic backwash bag filter 4 is fixedly connected to and connected to a discharge pipe 15. A flow meter is installed in the discharge pipe 15, and the discharge rate of the automatic backwash bag filter 4 is controlled by setting the flow meter.

[0033] The inlet of flushing pipe 5 is connected to inlet pipe 1, and the connection between flushing pipe 5 and inlet pipe 1 is located between automatic control valve 8 and centrifugal pump 7; the outlet of flushing pipe 5 is connected to the discharge pipe of automatic backwash bag filter 4. Automatic control valve 13 is installed on flushing pipe 5. A recovery tank 14 is connected to the automatic backwash bag filter. Both automatic control valves 13 and 4 are electrically connected to the controller.

[0034] In practical applications, automatic control valves can be selected from electric valves, hydraulic valves, pneumatic valves, and solenoid valves. The automatic flocculant cleaning device provided in this application is illustrated using polyaluminum chloride as an example; this device can also be applied to other flocculants.

[0035] The working process of the automatic flocculant removal device provided in this application is as follows:

[0036] When the online concentration meter 9 in the finished product tank 2 detects that the concentration of polyaluminum chloride exceeds the preset value, the controller sends a signal to open the automatic control valve 6, the centrifugal pump 7, and the automatic control valve 8. Under the action of the centrifugal pump 7, tap water is pumped into the finished product tank 2. When the online concentration meter 9 detects that the concentration of polyaluminum chloride has decreased to the target value, the controller sends a signal to close the automatic control valve 6, the centrifugal pump 7, and the automatic control valve 8.

[0037] When the online turbidity meter 10 in the finished product tank 2 detects that the turbidity of the flocs in the finished product tank 2 has reached the preset value, the controller sends a signal to start the homogenizing pump 11 and the automatic control valve 12. The homogenizing pump 11 extracts the flocs in the finished product tank 2 and disperses them. Then, the dispersed flocs are transported to the automatic backwash bag filter 4. The material processed by the automatic backwash bag filter 4 is discharged into the finished product tank 2 through the discharge pipe.

[0038] After the automatic backwash bag filter 4 completes the filtration work, there is filter residue remaining in the automatic backwash bag filter 4. The controller sends a signal to open the automatic control valve 6, the centrifugal pump 7, and the automatic control valve 13, so that tap water is flushed into the automatic backwash bag filter 4 from the discharge pipe, and the filter residue in the automatic backwash bag filter 4 is flushed into the recovery tank 14.

[0039] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
