DETAILED DESCRIPTION

[0035] EMBODIMENT

[0036] Referring to Figure 1 The embodiment provides a mobile grouting system, which comprises a feeding module 1, a pulping module 2, a grouting module 3 and a control module 4 which are sequentially detachably connected. The modules are independently and movably arranged, and the adjacent modules are detachably connected, so that the modules can be conveniently disassembled, installed and transported in blocks.

[0037] Further, the feeding module 1, the pulping module 2, the grouting module 3 and the control module 4 are sequentially arranged along a vertical line. The modules are arranged in a straight line along the slurry production and grouting process, are compactly arranged and save land.

[0038] In this embodiment, the feeding module 1 comprises one or more support frames 12 arranged transversely in parallel, and a feeding unit arranged detachably above the support frames 12. The pulp-making module 2 comprises one or more first containers 21 integrated internally with pulp-making units, and a feeding device detachably connected between the feeding unit and a lime injection port formed in the first container 21.

[0039] Preferably, referring to Figure 5 , the feeding unit comprises a horizontal lime tank 11 arranged transversely above the support frame 12, and the feeding device is a screw feeder 13. The lime tank 11 is provided with a lifting point at the top, and the lifting point is convenient for the root and hoisting of the rigging. Since the discharge port of the lime tank 11 is lower than the height of the lime injection port, the screw feeder 13 is arranged in sections, including a horizontal screw arranged below the lime tank 11, a climbing screw arranged between the horizontal screw and the lime injection port, and the climbing screw adopts a full-speed operation mode, and the conveying capacity of the climbing screw is greater than that of the speed-adjustable horizontal screw, so as to ensure the smooth flow of the lime and prevent the accumulation of the lime in the screw.

[0040] In a specific implementation, the lower part of the lime tank 11 is provided with five conical discharge bins, which can disperse and empty the lime in the lime tank 11. A manual butterfly valve is arranged at the lower part of the discharge bin to adjust the opening of the butterfly valve according to the discharging condition. The discharge bin is further provided with a rotation-preventing level indicator, and the level indicator is linked to control a pneumatic butterfly valve, so as to achieve lime discharging in sections, ensure the reserved ventilation space at the top of the bin, prevent the bin from being cracked due to poor exhaust, and avoid the excessive local pressure in the bin caused by uneven discharging.

[0041] The lower part of the butterfly valve is a horizontal screw, and the climbing screw is provided with a weighing sensor. The horizontal screw is controlled by a frequency converter, and the rotating speed is adjusted according to the signal of the weighing sensor of the climbing screw. When the weighing sensor detects that the current flow is greater than the set value, the horizontal screw reduces the speed to reduce the conveying of the lime. When the weighing sensor detects that the current flow is less than the set value, the horizontal screw increases the speed to increase the conveying of the lime, so as to realize intelligent control and ensure the accurate control of the discharging amount, thereby meeting the density requirement of pulp-making.

[0042] The mobile grouting station can continuously make pulp by using the flow water feeding mode of the screw feeder 13, and can maximize the production capacity of the equipment.

[0043] The support frame 12 adopts a double-layer steel structure design, the first layer has a height of 2000 mm, and the second layer has a height of 1000 mm. The structure is stable, the bearing capacity is high, and the size is matched with the lime tank 11.

When the slurry level reaches the overflow position, it flows by gravity into the secondary mixer 24 for further mixing and pulping, resulting in good pulping effect.

[0045] In this embodiment, the grouting module 3 is placed adjacent to the pulping module 2 and includes multiple second containers 31 with grouting pumps 33 integrated inside. A detachable grout delivery pipe is provided between the grouting pumps 33 and the pulping unit.
