Because the goaf area of a general mining area is wide and has many points, a pressurizing and conveying pump with enough pumping pressure is needed to carry out long-distance high-pressure conveying on filling slurry. Most of the pumps capable of realizing the long-distance high-pressure conveying function are volume type piston pumps or plunger pumps.
Since the displacement-type piston pump or plunger pump is characterized by sucking and pumping material according to the volume change of the pump cavity, the volume change inevitably causes the flow rate change of the conveyed material, and the flow rate change causes the generation of the pulsation impact phenomenon.

The check valve is a device for preventing material from flowing back at the moment when the conveying pump is reversed and does not pump when the material is conveyed upwards.
In addition, during transportation, failures such as pipe burst, leakage, pipe blockage and the like may occur in the operation condition of a long-distance pipeline, and therefore, it is necessary to effectively monitor fluid information including pressure and the like in the pipeline so as to reduce safety accidents.

Detailed Description
The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the invention.
Example (b): as shown in fig. 1 to 5, the pressurized pipeline conveying system of the present embodiment includes a continuous feeding device 1 and a conveying pipe 2, the continuous feeding device 1 includes a kneading and feeding device 11, a pressurized conveying pump 12 and a discharging pipe, a check valve 13 is installed at a feeding port of the kneading and feeding device 11, the check valve 13 is connected to a discharging port of an upstream feeding device, the discharging port of the kneading and feeding device 11 is communicated with the feeding port of the pressurized conveying pump 12, the discharging port of the pressurized conveying pump 12 is connected to the discharging pipe, a pulse current stabilizer 4 for stabilizing a fluid pulsation impact generated during the operation of the conveying pump and stabilizing a fluid flow is provided on the discharging pipe, the discharging pipe is connected to the conveying pipe 2, and a check valve 6 and a pressure sensor 7 are provided on the conveying pipe 2.
The functions and roles of the functional units of the present embodiment are as follows:
the check valve 13: the materials for conducting, controlling and isolating the upstream feeding process system enter the whole pressurized pipeline conveying system. In this embodiment, the stop valve 13 is a valve body described in patent application No. 2021203720565, and in a specific use process, the stroke of a valve plate of the stop valve 13 is controlled by a driving device, so that effective conduction is realized during normal conveying; when the low-flow conveying is carried out, effective flow control or throttling can be realized so as to control the feeding amount of an upstream feeding process system; when equipment fails, materials in an upstream feeding process unit can be isolated so as to facilitate maintenance and repair of downstream process equipment, and other references are not repeated herein.
The kneading and feeding device 11: for crushing, kneading and pressure feeding of the conveyed material. In this embodiment, a "paste pump feeding device" having a patent number of ZL201310235626.6 is preferably used. The structural principle of the feeding device of the paste pump is described in relevant documents. The paste pump feeding device preferably adopted by the invention can break up, rub and crush the materials, and meanwhile, the two built-in reverse helical blades push the materials, so that the pressure borne by the materials is increased, and the materials are pressed into the feeding port of the pressure delivery pump 12 at a certain pressure, thereby solving the problem that the pressure delivery pump 12 is difficult to suck the materials, and ensuring that the pressure delivery pump 12 has good volumetric efficiency
Pressure delivery pump 12: the pressurizing pipeline conveying system is used for pressurizing and conveying materials, and in the embodiment, the pressurizing pipeline conveying system preferably adopts a positive displacement piston pump or a plunger pump due to the characteristic that the positive displacement piston pump or the plunger pump can generate high pressure. Specifically, it is preferable to adopt "a spool valve hydraulic slurry pump" described in document CN202020477997.0, "a spool valve and a slurry pump including the same" described in document CN202020477139.6, "an automatic cone valve and a slurry pump including the same" described in document CN202020477065.6, "a valve hydraulic slurry delivery pump" described in document CN202020477141.3, and "a pipe delivery system" described in document CN 201920750944.9. The specific structure and principle of the above embodiments in the above documents are detailed in the related documents, and are not described herein. Since the pressurized delivery pump 12 according to the preferred embodiment has different structural and performance characteristics, it is purposefully selected according to the specific characteristics of the fluid to be delivered, so as to obtain the best pumping effect in practical engineering.
The pulse current stabilizer 4: the pump is used for stabilizing the impulse impact of fluid generated when the delivery pump works and enabling the liquid flow to be stable, specifically, in the process of reversing a plunger or a piston of the pressurizing delivery pump 12, the change of the delivery flow can be caused by the change of the volume of a pump cavity, the change can generate larger flow impulse under the action of the pump pressure, the flow impulse with larger kinetic energy acts on the outlet end of the pump and a subsequent pipeline to generate vibration, and the connection of the pipeline can be failed when the vibration is serious; the reaction force formed in the pipeline by the pulse impact can also cause adverse effect on the service life of the valve cavity of the delivery pump, and even the unstable pulse impact can also aggravate the erosion of materials to the pipeline, so that the design of the pulse current stabilizer 4 can well absorb and release pulse kinetic energy to stabilize the fluid pulse impact generated by the delivery pump; the pulse flow stabilizer 4 involved in the pressurized piping system in the present embodiment preferably employs a "paste pumping flow stabilizer" described in document zl201220691196.x, a "regulation type fluid pulsation damper" described in document CN201720106649.0, and a "flow stabilizer for a volumetric fluid apparatus" described in patent application No. 202022040923.3. The three technical products act on the floating piston through the fluid with pulse, and absorb and release the pulse kinetic energy through the elastic damping body to stabilize the fluid pulse impact generated by the delivery pump. The specific structure and principle of the above embodiments in the above documents are detailed in the related documents, and are not described herein.
A check valve 6: the device is used for preventing impact damage to the system caused by material backflow with high potential difference potential energy at the moment of reversing the pressurizing delivery pump 12.
The pressure sensor 7: the pressure measuring device is used for measuring the pressure condition in the conveying pipeline in real time and providing a judgment basis for judging the operation and fault conditions of the pipeline. In this embodiment, the pressure sensor 7 is a "flow-through paste pressure sensing device" described in the document ZL 201210542458.0. The diaphragm sleeve 714 of this type of pressure sensor 7 conforms to the inner diameter of the conduit 8 and does not create resistance to fluid flow; the problem of inaccurate measurement caused by the fact that materials easily enter the pressure guide hole to cause the blockage of the pressure guide hole or the metal diaphragm of the pressure transmitter 712 is easily abraded in the conventional measurement is solved. Because above-mentioned pressure sensor 7 has pressure signal teletransmission function, the pressure signal of actually surveying can be transmitted to conveying system's central control room, according to the change of pressure to unusual operating condition such as stifled pipe, reveal and blow out the existing warning suggestion of carrying out to do benefit to in time and deal with.
What needs to be supplemented is: in the embodiment, the pressure sensor 7 and the pressurizing delivery pump 12 are electrically connected with a remote central monitoring system through a power cable and a signal cable respectively and are subjected to remote central monitoring. Specifically, the remote central monitoring system mainly comprises an upper computer, a PLC programmable logic controller and a control cabinet, and these constituent units are common devices of an industrial automation control system and are not described in detail herein. The execution mechanism and the driving device for acquiring and controlling the operation state information of each functional unit in the embodiment are common control technologies and equipment in industry, and the embodiment is not specifically described.
What needs to be added specifically is: for the homogeneous slurry fluid with better fluidity, the pressurized pipeline conveying system of the embodiment does not need to be configured as the homogeneous slurry fluid with better fluidity, for example, the material kneading and feeding device 11 is not needed for the pressurized pipeline conveying of the homogeneous slurry fluid with better fluidity; when materials are conveyed downwards from the installation base surface of the pressure conveying pump 12, the materials do not flow back under the working condition, and the process unit and equipment for preventing the materials from flowing back can be realized without arranging the check valve 6.
