Embodiment Construction
[0045] The specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing:
[0046] like Figure 1~Figure 7 As shown, a large-scale ground grouting pumping station system includes a grouting pumping station arranged on the ground, and the grouting pumping station includes a water tank 1, a cement storage tank 2, a cement quantitative adding machine 3, an ejector 4, and a cement slurry A slurry storage tank 5, a cement slurry storage tank 2 6, a grouting pump 7, a mixer 8 and a control cabinet 9.
[0047] The water tank 1 is used to contain pulping water, and a water pump 10 is arranged in the water tank 1 , and the water pump 10 is electrically connected with the control cabinet 9 . The water pump 10 includes a pump body 101 and a water pump motor 102 for driving the pump body 101 . The pump body 101 and the water pump motor 102 are placed on the inside and outside of the water tank 1 respectively.
[0048] The suction port...

The invention relates to a large ground grouting pump station system which comprises a grouting pump station, the grouting pump station comprises a water tank, and a water pump and a first liquid level meter are arranged in the water tank; the cement storage tank is used for storing cement; the cement quantitative adding machine is communicated with the cement storage tank; the jet device is respectively communicated with the cement quantitative adding machine and the water pump; the first cement paste storage barrel, the second cement paste storage barrel, the jet device, the first cement paste storage barrel and the second cement paste storage barrel are sequentially communicated, and a second liquid level meter and a density meter are arranged in the second cement paste storage barrel; the grouting pump is communicated with the cement paste storage barrel II; the mixer is communicated with the grouting pump, a grout outlet of the mixer is further communicated with a high-pressure grout conveying pipeline, and a pressure sensor is arranged on the high-pressure grout conveying pipeline; and the control cabinet is used for controlling electric equipment. The invention further relates to a control method of the large ground grouting pump station system. According to the large ground grouting pump station capable of achieving automatic operation, full automation of pulping is achieved, the pulping efficiency is improved, and the large ground grouting pump station can be applied and popularized.
Description
technical field [0001] The invention relates to the technical field of pulping equipment, in particular to a large-scale ground grouting pumping station system and a control method. Background technique [0002] Reconstruction of geological bodies by grouting and other methods is an active method to maintain roadway stability. Because grouting has good sealing properties, it becomes a key means to control roadway deformation and water blocking and water control. [0003] Underground grouting in coal mines is widely used, mainly for grouting reinforcement, grouting water plugging, grouting fire prevention and sealing holes when gas is pumped, etc. According to the grouting flow, pressure and layout, it is divided into large-scale grouting pumping stations located on the ground and small-scale grouting pumping stations installed in coal mine underground roadways. [0004] For occasions where the grouting flow rate is not large, it is often the case that a small pulper is used...
