[0011] Preferably, the reflux pipe is snake-shaped, and a diverter pipe is fixedly connected to one end of the reflux pipe near the circulation pump. A valve is fixedly connected to the diverter pipe. The snake-shaped reflux pipe allows more solution to flow into the interior of the reflux pipe.

[0016] This utility model provides an anti-clogging device for the outlet of a chemical storage tank, which has the following beneficial effects:

[0017] 1. This device stores the solution in a storage tank and discharges the solution from the tank by opening the outlet pipe. The solution is filtered through a filter screen to remove particulate matter. As the liquid level in the storage tank drops, the buoyancy ring descends under the action of the counterweight. The pull rope pulls the winding wheel to unwind the winding, which in turn drives the connecting rod to rotate. The gear assembly drives the rotating rod to rotate, and the brush rod automatically cleans the surface of the filter screen, preventing the filter screen from becoming clogged and affecting normal liquid discharge.

[0018] 2. The device uses a spring to cause the buoyancy ring to rise inside the storage tank as new solution is poured in. The spring's rebound causes the winding wheel to rewind the rope. By activating the circulation pump, the solution circulates between the extraction pipe, return pipe, and storage tank, improving the uniformity of the solution inside the storage tank.

[0025] This utility model provides a device to prevent blockage at the outlet of a chemical storage tank.

[0026] Example 1:

[0027] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 A chemical storage tank outlet anti-clogging device includes a storage tank 1 and a circulation pump 2. The top and bottom of the storage tank 1 are respectively fixedly connected to an injection pipe 11 and an outlet pipe 12. One end of the outlet pipe 12 located inside the storage tank 1 is fixedly connected to a fixed cylinder 3. A filter screen 4 is fixedly connected to the top of the fixed cylinder 3. A slag discharge pipe 13 is fixedly connected to the bottom of the storage tank 1. Valves are fixedly connected to both the outlet pipe 12 and the slag discharge pipe 13. A liquid level sensor 14 is fixedly connected to the inner wall of the storage tank 1. The solution inside the storage tank 1 is discharged by opening the valve on the outlet pipe 12. The filter screen 4 filters particulate impurities in the solution. The valve on the slag discharge pipe 13 is opened to discharge the filtered particulate impurities. The liquid level sensor 14 monitors the liquid level inside the storage tank 1 in real time.

[0028] Please refer to it again. Figure 1 , Figure 2 and Figure 3 A fixed base 5 is fixedly connected to the upper part of the inner wall of the liquid storage tank 1. A rotating rod 6 is rotatably connected to the bottom of the fixed base 5. A brush rod 61 for cleaning the filter screen 4 is fixedly connected to the bottom of the rotating rod 6. The rotating rod 6 is driven to rotate, and the filter screen 4 is cleaned by the brush rod 61. The liquid storage tank 1 includes a tank body and a bottom cover. The tank body and the bottom cover are detachably connected by bolts. By removing the bolts between the tank body and the bottom cover, it is convenient to clean the inside of the liquid storage tank 1.

[0029] Example 2:

[0030] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 The bottom of the fixed base 5 is provided with a buoyancy ring 8. The fixed base 5 is rotatably connected to a connecting rod 7. A winding wheel 71 is fixedly connected to the connecting rod 7. A pull rope is wound on the winding wheel 71. The other end of the pull rope is fixedly connected to the buoyancy ring 8. A counterweight 81 is fixedly connected to the buoyancy ring 8. The connecting rod 7 and the rotating rod 6 are connected by a gear assembly. The buoyancy ring 8 is ring-shaped and hollow inside. The buoyancy ring 8 is made of polyethylene. Under the action of buoyancy, the buoyancy ring 8 rises as the liquid level inside the liquid tank 1 rises. When the liquid level inside the liquid tank 1 falls, the counterweight 81 pulls the pull rope to unwind on the outer surface of the winding wheel 71, thereby driving the connecting rod 7 to rotate inside the fixed base 5. The weight of the counterweight 81 is less than the buoyancy of the buoyancy ring 8.

[0031] Please refer to it again. Figure 1 , Figure 2 and Figure 3The gear assembly includes a first bevel gear fixed to the top of the rotating rod 6, and a second bevel gear fixedly connected to the outer surface of the connecting rod 7. The first bevel gear meshes with the second bevel gear, and the connecting rod 7 rotates under the meshing action of the first bevel gear and the second bevel gear, which in turn drives the rotating rod 6 to rotate.

[0032] Please refer to it again. Figure 1 , Figure 2 and Figure 3 Both inner walls of the fixed base 5 are fixedly connected with springs 72. The other end of the springs 72 is fixedly connected to the connecting rod 7. When the buoyancy ring 8 rises, the springs 72 drive the connecting rod 7 to rotate in the opposite direction. The winding wheel 71 winds up the rope. The weight of the counterweight 81 is greater than the elastic force of the springs 72.

[0033] Example 3:

[0034] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 The input end of the circulation pump 2 is equipped with a suction pipe 21 that is connected to the bottom of the storage tank 1. The output end of the circulation pump 2 is fixedly connected to a return pipe 22. The other end of the return pipe 22 is connected to the storage tank 1. The return pipe 22 is snake-shaped. The end of the return pipe 22 near the circulation pump 2 is fixedly connected to a diverter pipe. A valve is fixedly connected to the diverter pipe. By starting the circulation pump 2, the solution inside the storage tank 1 is drawn through the suction pipe 21, and then the solution is transported back to the inside of the storage tank 1 for circulation through the return pipe 22. The suction pipe 21 is a flexible tube, and the return pipe 22 is a rigid tube. Most of the components of the device are made of materials with good chemical resistance. Other materials are coated with paint to improve their chemical resistance. It is necessary to perform positioning maintenance on each component.

[0035] Working principle: The solution is injected into the storage tank 1 through the injection pipe 11 for storage. When liquid needs to be removed, the solution inside the storage tank 1 is discharged by opening the valve on the outlet pipe 12. The filter screen 4 filters out particulate impurities in the solution. As the liquid level inside the storage tank 1 drops, the buoyancy ring 8 descends under the action of the counterweight 81, pulling the winding wheel 71 at the other end of the rope to unwind it, thereby driving the connecting rod 7 to rotate inside the fixed base 5. Under the meshing action of the first bevel gear and the second bevel gear, the rotating rod 6 rotates. The brush rod 61 at the bottom of the rod 6 cleans the surface of the filter screen 4 to prevent impurities from clogging the filter screen 4 and affecting normal liquid output. The circulation pump 2 is started to draw the solution inside the storage tank 1 through the liquid extraction pipe 21, and then the solution is transported back to the inside of the storage tank 1 through the return pipe 22 for circulation. Since the path of the return pipe 22 is relatively long, the liquid level inside the storage tank 1 can also be lowered by the circulation method. When new solution is injected into the storage tank 1, the buoyancy ring 8 rises under the action of buoyancy, and the spring 72 drives the winding wheel 71 to rewind the pull rope.
