[0030] The present invention will be further described below with reference to the accompanying drawings.

[0031] Please see Figure 1-6 This embodiment provides an anti-clogging geopolymer high-pressure grouting pumping device, including a base 1. A double-cylinder plunger pump 2 is fixedly connected to the top of the base 1. An anti-clogging component 3 is fixedly connected to the inlet of the double-cylinder plunger pump 2 by bolts. A quick-change component 4 is provided at the outlet of the double-cylinder plunger pump 2. A grouting nozzle 5 is movably connected to the inner cavity of the quick-change component 4. A monitoring component 6 is fixedly connected to the inner cavity of the double-cylinder plunger pump 2. The anti-clogging component 3 includes a miniature vibration motor 31 fixedly connected to the pump cavity of the double-cylinder plunger pump 2 and a self-cleaning device fixedly connected to the inlet of the double-cylinder plunger pump 2 by bolts. The output end of the micro vibration motor 31 is fixedly connected to the cleaning component 32, and the quick-change component 4 includes a fitting groove 41 opened on the surface of the discharge port of the double-cylinder plunger pump 2. The inner cavity of the fitting groove 41 is slidably connected to the fitting block 42. The other side of the fitting block 42 is fixedly connected to the grouting nozzle 5. The surface of the discharge port of the double-cylinder plunger pump 2 is fitted with a fixing screw sleeve 43, and the fixing screw sleeve 43 is threadedly connected to the surface of the grouting nozzle 5. The monitoring component 6 includes a flow meter 61 fixedly connected to the inner cavity of the discharge port of the double-cylinder plunger pump 2 and a pressure sensor 62 fixedly connected to the pump chamber of the double-cylinder plunger pump 2.

[0032] The self-cleaning component 32 includes a feed pipe 321 fixedly connected to the feed port of the dual-cylinder plunger pump 2 by bolts. Both ends of the inner cavity of the feed pipe 321 are fixedly connected to stainless steel filter screens 322 by bolts. A three-way flushing valve 323 is connected to the top of the feed pipe 321, and electromagnetic waste discharge valves 324 are connected to both sides of the bottom of the feed pipe 321. The double-layer stainless steel filter screens 322 achieve graded filtration and improve the impurity interception effect. The three-way flushing valve 323 can introduce water to backwash the stainless steel filter screens 322, and the electromagnetic waste discharge valve 324 can quickly discharge the intercepted impurities. The three work together to form a complete self-cleaning cycle, reducing the frequency of manual cleaning and maintaining smooth feeding.

[0033] The three-way flushing valve 323 is located at the discharge end of the stainless steel filter screen 322, and the electromagnetic waste discharge valve 324 is located at the feed end of the stainless steel filter screen 322. This design allows the cleaning medium to accurately flush the trapped material on the surface of the filter screen during backwashing and discharge it directly through the waste discharge valve at the feed end, thereby improving flushing efficiency and avoiding secondary pollution from impurities.

[0034] The surface of the vibration guide plate 33 is provided with multiple guide grooves. The guide grooves can guide the material to flow along a preset path, reduce turbulence generation, and enhance the disturbance effect of vibration on the material, further preventing particle deposition and improving anti-clogging performance.

[0035] The inner cavity of the fixing sleeve 43 is provided with an internal thread, and the surface of the grouting nozzle 5 is provided with an external thread that matches the internal thread. The internal thread and the external thread are precisely matched, and the grouting nozzle 5 is rigidly fixed through the threaded connection to ensure the connection sealing during high-pressure grouting and to prevent grout leakage.

[0036] The surface of the fixed threaded sleeve 43 is fixedly connected with a handle, which makes it easy for construction personnel to quickly rotate the threaded sleeve to replace the grouting nozzle 5, thus improving the ease of operation.

[0037] Sealing rings are fitted between the grouting nozzle 5 and the discharge port of the double-cylinder plunger pump 2, as well as between the self-cleaning component 32 and the inlet of the double-cylinder plunger pump 2. The sealing rings can effectively enhance the sealing of the connection between the grouting nozzle 5 and the discharge port, and between the self-cleaning component 32 and the inlet, to prevent high-pressure grout leakage and ensure stable equipment working pressure.

[0038] Specifically: The dual-cylinder plunger pump 2 has a maximum output pressure ≥30MPa, with the output pressure orifice controlled at 25MPa. The pump body is internally plated with a hard chrome layer for wear and corrosion resistance. The stainless steel filter screen has a pore size ≤1mm. The grouting nozzle 5 supports Φ10-50mm to adapt to different working conditions; a Φ20mm grouting nozzle 5 is selected. The pressure sensor 62 monitors a pressure <30MPa for normal operation. The flow meter 61 monitors a flow rate ≥10L / min. If the pressure suddenly rises ΔP>5MPa / 10s, the micro-vibration motor 31 drives the vibration guide plate 33 and triggers an alarm. The micro-vibration motor 31 has a vibration frequency of 50-100Hz, and the vibration guide plate 33 has a vibration frequency controlled at 80Hz to enhance the anti-clogging effect. The guide groove has a depth of 2-3mm and an inclination angle of 15°. The reverse flushing water pressure is ≥5MPa. The stainless steel filter screen 32 is cleaned for 2 to 30 seconds. Every 50 hours, the pump chamber of the dual-cylinder plunger pump 2 is disassembled to check the plating wear; the filter screen sealing ring is replaced, and the plunger connecting rod is lubricated.

[0039] The working principle of this utility model is as follows: the geopolymer material enters the double-cylinder plunger pump 2 through the self-cleaning component 32, and after being filtered by the stainless steel filter screen 322, it is transported by the high-pressure power provided by the double-cylinder plunger pump 2. The micro vibration motor 31 drives the vibration guide plate 33 to vibrate continuously, which, together with the guide groove, guides the material flow and prevents sedimentation and blockage in the pump chamber. If the stainless steel filter screen 322 becomes blocked, water can be introduced through the three-way flushing valve 323 for reverse flushing. Impurities are discharged through the electromagnetic waste discharge valve 324. During the grouting process, the flow meter 61 and the pressure... Force sensor 62 monitors the flow rate at the discharge port and the pump chamber pressure in real time to ensure stable equipment operation. When the grouting nozzle 5 needs to be replaced, rotate the fixing sleeve 43 to separate it from the grouting nozzle 5. Remove the old grouting nozzle 5 through the sliding fit between the fitting block 42 and the fitting groove 41. After replacing the new grouting nozzle 5, rotate the fixing sleeve 43 in the opposite direction to complete the installation. The alternating working mode of the double-cylinder plunger pump 2 ensures that the grouting process is continuous and uninterrupted. The sealing rings of each connection part ensure the sealing performance under high pressure conditions. The whole system achieves efficient, stable and anti-clogging high-pressure grouting operation.

[0040] The above embodiments are merely preferred embodiments of this utility model, and the protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that improvements and modifications made by those skilled in the art without departing from the principle of this invention should also be considered within the protection scope of this utility model.
