Description

Technical Field

[0001] This invention relates to the field of pulping equipment technology, specifically to a pulping machine. Background Technology

[0002] In engineering fields such as goaf remediation, tunnel grouting, highway ground reinforcement, and coal mine water control, grouting equipment is the core equipment for grouting operations, and its performance directly affects grouting efficiency and project quality. Currently, traditional grouting systems mostly adopt a decentralized layout, that is, the water supply device, grouting host, grout storage equipment, and electrical control system required for grouting are independent units, which need to be temporarily assembled and debugged on site.

[0003] Dispersed equipment units need to be placed one by one on the construction site, connected to pipelines (such as water supply pipes and slurry delivery pipes), and temporary circuits and gas lines need to be set up. This not only consumes a lot of manpower and time, but also requires professional personnel to debug, which increases the cost of temporary construction and the pressure on the construction period. In the case of tunnels, underground and other working environments with limited space, distributed equipment occupies a large area, and each unit needs to be moved individually, making it difficult to flexibly adjust its position, which limits its application in complex terrain. Summary of the Invention

[0027] like Figures 1-3 As shown, an embodiment of the present invention provides a pulping machine that may include a skid-mounted body 10, a horizontal ribbon pulping machine 20, a water supply mechanism 30, a screw conveyor 40, and a pulp storage mechanism 50.

[0028] Specifically, the horizontal ribbon pulper 20 is installed inside the skid-mounted body 10 and is used to prepare slurry; the water supply mechanism 30 is installed on the skid-mounted body 10 and is used to supply water to the horizontal ribbon pulper 20; the slurry storage mechanism 50 is installed inside the skid-mounted body 10 and is located below the horizontal ribbon pulper 20, and the slurry prepared by the horizontal ribbon pulper 20 is discharged into the slurry storage mechanism 50.

[0029] During pulping, pulp is conveyed into the horizontal ribbon pulper 20 via a screw conveyor 40.

[0030] This invention integrates the functions of electrical control, water supply, pulping, pulp storage, and pneumatic devices required for pulping into a single skid-mounted structure. It features convenient transportation and installation, high degree of automation, and wide applicability, and can be widely used in engineering fields such as goaf treatment, tunnel grouting, highway ground grouting reinforcement, and coal mine water control and fire prevention grouting.

[0031] Specifically, the skid-mounted structure integrates all functional components required for pulping (including the pulping system, water supply mechanism, screw conveyor, mixer, pneumatic device, control system, etc.) into a unified load-bearing frame through mechanical fixing, forming an integral, movable unit. Its core function is to replace the on-site assembly mode of traditional decentralized pulping equipment, achieving the functions of "integrated transportation, rapid placement, and immediate use." In use, it can be transported to the work site as a whole using trailers or other equipment.

[0032] In this embodiment of the invention, the horizontal ribbon pulper 20 is located above the pulp storage mechanism 50, and adopts a vertical layout of "high-level pulping + low-level pulp storage" to reduce the horizontal space occupied and adapt to narrow working scenarios (such as tunnels and underground).

[0033] like Figures 1-3As shown, in one embodiment of the present invention, the horizontal ribbon pulper 20 may include a base, a pulping tank 21, a stirring shaft, a stirring ribbon, and a pulping reduction motor 22.

[0035] like Figures 1-3 As shown, in one embodiment of the present invention, the water supply mechanism 30 may include a water tank 31 and a submersible pump 32. The water tank 31 is mounted on the skid-mounted body 10; the submersible pump 32 is located inside the water tank 31 and is connected to the horizontal ribbon pulper 20 via a water pipe, on which an electromagnetic flow meter 33 is installed. The submersible pump 32 is model 100QW100-15-7.5-4, with a diameter of 100mm, a flow rate of 100m³ / h, and a head of 15 meters; the electromagnetic flow meter 33 is model HDLD-1013A111DC-1-JR, used as a reference for adjusting the valve opening during continuous pulping.

[0036] like Figures 1-3 As shown, in one embodiment of the present invention, the slurry storage mechanism 50 may include a slurry storage tank 51, a stirring reduction motor 52, and a stirring paddle. The slurry storage tank 51 is mounted on a skid-mounted body 10; multiple stirring reduction motors 52 are fixedly mounted on the top of the slurry storage tank 51; and the stirring paddle is located inside the slurry storage tank 51 and is fixedly connected to the output end of the stirring reduction motor 52.

[0037] In a specific embodiment of the present invention, three mixers are connected in parallel. The diameter of the mixer blade is 11000mm and the height is 1000mm. The model of the mixer reduction motor 52 is: KAF87-79.34-Y3KW / 4P-A-M5.

[0038] like Figures 1-3 As shown, in one embodiment of the present invention, the slurry storage tank 51 is provided with a plurality of slurry discharge valves 53 for connecting the grouting pump. The slurry discharge valves 53 are pneumatic valves. The skid body 10 is provided with a pneumatic device for controlling the slurry discharge valves 53, including an air compressor 54 and a refrigerated dryer 55. The air compressor 54 and the refrigerated dryer 55 are connected through an air pipe. The refrigerated dryer 55 is connected to the slurry discharge valve through an air pipe.

[0039] The air compressor is a three-cylinder piston air compressor. As a valve-controlled air source, the air compressor has an air output of 0.9 m³ / min and a maximum pressure of 0.8 MPa; the refrigerated dryer has a maximum air volume of 1.5 m³ / min.

[0040] like Figures 1-3 As shown, in one embodiment of the present invention, a control room is provided on the skid-mounted body 10, and a power distribution control cabinet is provided in the control room. The stirring geared motor 52, air compressor 54, refrigerated dryer 55, submersible pump 32, electromagnetic flowmeter 33, and pulping geared motor 22 are electrically connected to the power distribution control cabinet. The power distribution control cabinet includes air switches, contactors, residual current circuit breakers, thermal relays, frequency converters, etc., and has three-level leakage protection function. It also includes a PLC control system, and the PLC can be selected from the Siemens S7-200 smart series.

[0041] In one embodiment of the present invention, a liquid level sensor is provided in the water tank 31 and the slurry storage tank 51, and the liquid level sensor is electrically connected to the power distribution control cabinet.

[0042] like Figure 3 As shown, in one embodiment of the present invention, the invention further includes a computer control console, which is communicatively connected to the power distribution control cabinet. The computer control console deploys configuration software on its host computer. The host computer and equipment execute the TCP / IP protocol and are connected via Ethernet for remote start / stop control and monitoring of relevant parameters. The equipment operates fully automatically without human intervention. The slurry ratio can be set through the corresponding operating interface, and pulping production data can be viewed through the production statistics interface. Sensor calibration can be performed through the parameter setting interface. The computer control console achieves fully automatic control of the entire station's equipment, providing comprehensive automatic monitoring and real-time data transmission for all equipment. Specifically, the computer control console can view and record the operating parameters of each piece of equipment in real time, such as water supply flow rate, air pressure, water tank level, slurry tank level, pulping times, cumulative pulping volume, cumulative powder content, and other parameters. It can also generate daily, monthly, and annual reports, as well as various categorized statistical reports. Furthermore, it can automatically start and stop various pulping equipment according to set parameters, automatically adjust the water and ash ratios, and precisely control the slurry ratio.

[0043] When using the equipment, move it to a suitable, level work site, shim it, and check that all parts are intact and connections are secure. After leveling the work site, lay the pipelines and install the equipment. Using the control panel or touchscreen interface, set the relevant parameters such as slurry mixing ratio, slurry volume, grouting pressure, and grouting flow rate according to project requirements.

[0044] During pulping, the submersible pump is turned on to allow water from the water tank to enter the pulping tank, and the weighing sensor starts weighing at the same time. When the water reaches the predetermined weight, the water intake stops, and the screw conveyor starts feeding material. The weighing sensor weighs again, and when the material reaches the predetermined weight, the feeding stops. The pulping reduction motor of the horizontal screw pulper starts working to perform stirring. After the slurry is stirred evenly, the discharge valve is opened to release the slurry into the storage tank.

[0045] During grouting, a grouting command is issued, and pressure grouting begins via a grouting pump. Throughout the grouting process, sensors monitor grouting parameters in real time to ensure the process follows the set parameters. If any parameters deviate, the control system will automatically adjust or issue an alarm to prompt operator intervention.

[0046] After completing one grouting operation, add clean water to clean the grouting equipment and flush the grouting pipeline. After cleaning, turn off the brake switch. If it is necessary to continue construction in other sections, the grouting machine can be moved to the corresponding location, and the above operation procedure can be repeated.

[0047] According to an embodiment of the present invention, a grouting machine integrates water supply, power supply, grouting and storage functions. It has a compact structure, is flexible in movement, and is particularly suitable for places with limited working space. It is easy to use and eliminates the need for temporary equipment assembly and dismantling work at grouting stations, thus saving construction costs.
