[0040] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. All other embodiments obtained by ordinary technicians in this field without creative work based on the embodiments of the present invention are within the scope of protection of the present invention.

[0041] like Figures 1 to 4 As shown, an embodiment of the present invention provides a grouting device, which includes a slurry making part 10, a slurry storage part 20, a grouting pump 30 and a diversion component 40, the slurry making part 10 includes a slurry making tank 11, the slurry making tank 11 has a material inlet 1101 and a first slurry outlet 1102; the slurry storage part 20 includes a first chamber 201 and a second chamber 202 that are independent of each other, the slurry storage part 20 is also provided with a first slurry inlet 203 and a first slurry outlet 204, the first slurry inlet 203 is communicated with the first chamber 201, and the first slurry inlet 203 is also connected to the first slurry outlet 11 02 is connected, the first slurry outlet 204 is connected with the second chamber 202; the slurry suction port of the grouting pump 30 is connected with the first slurry outlet 204; the guide assembly 40 includes a guide pipe 41 and a guide pump 42, the first end of the guide pipe 41 extends into the first chamber 201 and is sealed and connected with the first chamber 201, the second end of the guide pipe 41 extends into the second chamber 202 and is sealed and connected with the second chamber 202, the guide pump 42 is arranged on the guide pipe 41, and the guide pump 42 can suck the fluid in the first chamber 201 into the second chamber 202.

[0042] By applying the technical solution of the present invention, the relative positions of the slurry making section 10 and the slurry storage section 20 are not limited in the height direction. Specifically, the slurry making section 10, the slurry storage section 20 and the grouting pump 30 are connected in sequence, the slurry storage section 20 has a first chamber 201 and a second chamber 202 which are independent of each other, the flow guide pipe 41 of the flow guide assembly 40 connects the first chamber 201 and the second chamber 202, after the slurry making section 10 performs slurrying operation, the flow guide pump 42 sucks air into the second chamber 202, so that a negative pressure environment is formed in the first chamber 201, under the action of the negative pressure, the slurry in the slurry making section 10 flows into the first chamber 201, when the height of the slurry in the first chamber 201 exceeds the height of the first end of the flow guide pipe 41, the flow guide pump 42 sucks the slurry in the first chamber 201 into the second chamber 202; thereafter, the grouting pump 30 performs grouting operation. In the traditional technical solution, it is necessary to dig a separate slurry storage pool and place the slurry storage tank in the slurry storage pool so that the height of the slurry storage tank is lower than the height of the pulping machine to ensure that the slurry in the pulping machine can flow smoothly into the slurry storage tank. Compared with the traditional technical solution, the setting of this solution does not need to deliberately place the pulping part 10 above the slurry storage part 20. After the negative pressure is formed in the first chamber 201, the slurry in the pulping part 10 can flow into the first chamber 201 under the action of the negative pressure; then, through the action of the diversion pump 42 and the diversion pipe 41, the slurry in the first chamber 201 flows into the second chamber 202. The setting of this solution improves the convenience of the grouting process.

[0043] Furthermore, in the present solution, the slurry storage section 20 is divided into an independent first chamber 201 and a second chamber 202, so that the slurry injection and discharge processes of the slurry storage section 20 can be carried out relatively independently without affecting each other, thereby improving the stability of the working process of the slurry storage section 20.

[0044] In addition, it is also possible to store newly prepared new slurry separately from previously prepared slurry, and grouting can be performed according to the preparation batch of the slurry to improve the grouting quality. In addition, the diversion pump 42 in the diversion component 40 can pump the slurry in the first chamber 201 to the second chamber 202, which has strong controllability for slurry transfer.

[0045] In the embodiment of the present solution, the pulping part 10 further includes a driving part 12, a transmission part 13 and a stirring part, and the stirring part is movably arranged in the pulping tank 11 and stirs the material. The driving part 12 outputs power, and the driving part 12 is connected to the stirring part through the transmission part 13, so that the stirring part stirs the material in the pulping tank 11.

[0046] Specifically, the pulping material enters the pulping tank 11 from the material inlet 1101, and the material in the pulping tank 11 is fully stirred by the stirring part to form slurry, and the prepared slurry flows out of the pulping part 10 through the first slurry outlet 1102, and then enters the first chamber 201 of the slurry storage part 20 through the first slurry inlet 203; the diversion pump 42 is started, and the diversion pump 42 sucks the air in the first chamber 201 into the second chamber 202, so that a negative pressure is formed in the first chamber 201; the slurry in the pulping part 10 can flow smoothly from the pulping part 10 to the slurry storage part 20 under the action of the pressure difference; the diversion pump 42 sucks the slurry in the first chamber 201 into the second chamber 202 through the diversion pipe 41, so that the slurry is temporarily stored in the second chamber 202, and when grouting operation is required, the grouting pump 30 is started, and the grouting pump 30 pumps the slurry in the second chamber 202 to the grouting location.

[0047] In the embodiment of this solution, the first pulp outlet 1102 is arranged at the bottom of the pulping tank 11. Such arrangement facilitates the outflow of the pulp in the pulping tank 11.

[0048] In the embodiment of the present solution, the grouting device further includes a flow meter 110, which is disposed at the first slurry outlet 204. The flow meter 110 can monitor in real time the amount of slurry pumped out of the second chamber 202 by the grouting pump 30. The grouting pump 30 is turned on or off according to the grouting amount monitored by the flow meter 110, and the grouting amount of the grouting pump 30 can be accurately controlled, thereby improving the controllability of the grouting operation.

[0049] like Figure 3 As shown, further, the grouting device also includes a connecting structure 50, which is arranged on the slurry storage part 20, and the connecting structure 50 has a closed state and a connected state. When the connecting structure 50 is in the closed state, the second chamber 202 is separated from the external environment of the slurry storage part 20; when the connecting structure 50 is in the connected state, the second chamber 202 is connected to the external environment of the slurry storage part 20 through the connecting structure 50.

[0050] Specifically, the connecting structure 50 is connected to the second chamber 202. In the process of pumping the slurry from the first chamber 201 to the second chamber 202, the connecting structure 50 is kept in a connected state, so that the second chamber 202 is connected to the external environment of the slurry storage part 20 through the connecting structure 50, and then the diversion pump 42 is turned on to form a negative pressure in the first chamber 201, and the slurry is pumped into the second chamber 202. Such a configuration facilitates the formation of a negative pressure state in the first chamber 201. Similarly, after starting the grouting pump 30, the connecting structure 50 is placed in a connected state. Such a configuration facilitates the grouting operation of the grouting pump 30. When the grouting device is idle, the connecting structure 50 can be placed in a closed state to reduce or prevent external debris from falling into the second chamber 202.

[0051] In the embodiment of the present solution, the diversion pump 42 is a two-way diversion pump, which can pump the fluid in the second chamber 202 into the first chamber 201. In this way, the diversion pump 42 can pump the slurry from the first chamber 201 to the second chamber 202, and can also pump the slurry from the second chamber 202 back to the first chamber 201, so as to realize the circulation of the slurry between the first chamber 201 and the second chamber 202, which is conducive to the uniform mixing of the slurry, and can also reduce the hardening of the slurry, which is conducive to the storage of the slurry for a long time and maintain the quality of the slurry.

[0052] Specifically, the communication structure 50 includes a communication port 51 and a blocking portion 52. The communication port 51 is provided on the slurry storage portion 20 and communicates with the second chamber 202. The blocking portion 52 is provided at the communication port 51 and is used to block or open the communication port 51. In this way, the connection state between the second chamber 202 and the outside world can be conveniently switched by blocking or opening the communication port 51 with the blocking portion 52, thereby improving the operational flexibility of the grouting device.

[0053] In the embodiment of the present solution, the height of the first end of the flow guide tube 41 is higher than the height of the first slurry inlet 203. With such a configuration, after the slurry enters the first chamber 201 for a period of time, the flow guide pump 42 can still continue to pump the air in the first chamber 201 into the second chamber 202, so that the pressure in the first chamber 201 continues to be maintained in a negative pressure state; and, the first end of the flow guide tube 41 is arranged above the first slurry inlet 203, so that the slurry can enter the first chamber 201 from the first slurry inlet 203 more smoothly, and as the slurry gradually enters, the liquid level of the slurry in the first chamber 201 gradually rises, and when the liquid level of the slurry rises to the height of the first end of the flow guide tube 41, the flow guide tube 41 can pump the slurry to the second chamber 202.

[0054] Specifically, the first slurry inlet 203 is disposed at the bottom of the first chamber 201 .

[0055] In the embodiment of the present scheme, the first end of the guide tube 41 is movably arranged in the height direction to pass through the top of the pulping tank 11. In this way, the height difference between the first end of the guide tube 41 and the first slurry inlet 203 can be adjusted, and the time for the slurry in the first chamber 201 to be pumped into the second chamber 202 can be adjusted.

[0056] Furthermore, the height of the first end of the flow guide pipe 41 is lower than the height of the second end of the flow guide pipe 41. Setting the first end of the flow guide pipe 41 to be lower than the second end of the flow guide pipe 41 in the height direction can effectively reduce the slurry backflow phenomenon, reduce the uncontrolled backflow of slurry from the second chamber 202 to the first chamber 201, and improve the stability of the grouting device.

[0057] like Figure 3As shown, further, the grouting device also includes a liquid level detection unit 60 and a control system 70. The liquid level detection unit 60 is arranged in the second chamber 202, and the liquid level detection unit 60 is used to detect the liquid level of the slurry in the second chamber 202; the control system 70 is electrically connected to the liquid level detection unit 60 and the grouting pump 30 respectively. When the liquid level detection unit 60 detects that the liquid level of the slurry in the second chamber 202 is lower than a preset value, the control system 70 controls the grouting pump 30 to close.

[0058] The above arrangement can monitor the liquid level of the slurry in the second chamber 202 in real time through the liquid level detection unit 60, and transmit the monitored liquid level signal to the control system 70. When the liquid level is lower than the preset minimum value, the control system 70 automatically shuts down the grouting pump 30 to prevent the grouting pump 30 from running dry when the slurry in the second chamber 202 is insufficient, thereby improving the safety of the grouting device. At the same time, the automatic control of the grouting pump 30 by the control system improves the automation and reliability of the grouting device.

[0059] like Figure 2 and Figure 3 As shown, further, the grouting device also includes a filter tank 80 and a filter part 90, the filter tank 80 has a second slurry inlet 801 and a second slurry outlet 802; the filter part 90 is arranged in the filter tank 80 to separate the filter tank 80 into a third chamber and a fourth chamber that are independent of each other; wherein the first slurry outlet 1102 is connected to the second slurry inlet 801, and the second slurry inlet 801 is connected to the third chamber; the fourth chamber is connected to the second slurry outlet 802, and the second slurry outlet 802 is connected to the first slurry inlet 203.

[0060] Specifically, the third chamber is located above the fourth chamber, and the slurry made by the slurry making part 10 enters the third chamber of the filter tank 80 through the second slurry inlet 801, and the slurry then falls on the filter part 90. The filter part 90 is specifically a screen, which can filter out some impurities and larger particles in the slurry, and the filtered slurry falls into the fourth chamber, and then enters the slurry storage part 20 through the second slurry outlet 802. The filter tank 80 and the filter part 90 filter the slurry before the slurry enters the slurry storage part 20, which improves the slurry quality and is conducive to improving the overall efficiency and reliability of the grouting operation.

[0061] In the embodiment of the present scheme, a slag outlet is also provided on the side of the third chamber, and a plugging member is provided at the slag outlet, and the plugging member is used to plug or open the slag outlet. The grouting device also includes a slag collecting box 81, which is located below the filter tank 80. The impurities and larger particles filtered out by the filter unit 90 can be collected in the slag collecting box 81, and then the impurities, particles, etc. in the slag collecting box 81 are collectively discharged.

[0062] like Figure 2As shown, further, the grouting device also includes a vibration base 100 , and the filter tank 80 is arranged on the vibration base 100 .

[0063] In this solution, the vibration base 100 can vibrate when the filter tank 80 filters the slurry, so that the filter tank 80 vibrates, which is beneficial to the filtering process of the slurry and improves the filtering efficiency of the filter part 90 for the slurry. At the same time, the vibration of the filter part 90 can reduce the situation where impurities or larger particles clog the filter screen and improve the smoothness of the slurry filtering process.

[0064] like Figure 1 As shown, in the embodiment of the present scheme, the grouting device can be arranged on the trailer 120, and the trailer 120 can transport the grouting device to different work sites, thereby improving the flexibility of the grouting device. The trailer 120 includes a carriage plate, a skid-mounted shell 1201 is arranged on the carriage plate, the grouting device is arranged in the skid-mounted shell 1201, and a lifting point 1203 is also arranged on the top of the skid-mounted shell 1201. The lifting device can lift the skid-mounted shell 1201 as a whole through the lifting point 1203 and transfer it to the grouting site. A hydraulic support 1202 is also arranged on the side of the carriage plate, and the hydraulic support 1202 provides support for the carriage plate in the extended state, and the hydraulic support 1202 will not interfere with the operation of the trailer 120 in the retracted state.

[0065] like Figures 1 to 4 As shown, further, the embodiment of the present invention also provides a grouting method, which uses the grouting device provided in the above embodiment. The grouting method includes the following steps:

[0067] During the pulp storage process in the first chamber 201: the diversion pump 42 is started, and the diversion pump 42 first draws the air in the first chamber 201 into the second chamber 202 until the pressure in the first chamber 201 is lower than the pressure in the pulp making section 10, and the pulp flows from the first pulp outlet 1102 into the first chamber 201; during this process, the second chamber 202 is ensured to be connected to the environment outside the pulp storage section 20;

[0068] Slurry storage process in the second chamber 202: when the height of the slurry in the first chamber 201 is higher than the first preset height, the diversion pump 42 draws the slurry in the first chamber 201 into the second chamber 202 through the diversion pipe 41;

[0069] Grouting process: When the slurry in the second chamber 202 reaches a second preset height, the grouting pump 30 is started, and the grouting pump 30 pumps the slurry in the second chamber 202 to the target scene; wherein the first preset height is higher than the height of the first end of the guide tube 41, and during this process, the second chamber 202 is ensured to be connected to the environment outside the slurry storage section 20.

[0070] Specifically, after the pulping section 10 completes pulping, the slurry is filtered through the filter tank 80 and the filter section 90 before entering the slurry storage section 20. The filtered slurry is then input into the first chamber 201 to improve the reliability of the grouting process.

[0071] After the grouting process is stopped, the grouting method further includes a grout storage part 20 cleaning process, and the grout storage part 20 cleaning process includes:

In this process, the second chamber 202 is ensured to be connected to the environment outside the pulp storage section 20;

In this process, the second chamber 202 is isolated from the external environment;

[0075] The diversion pump 42 performs a second reversal, and the diversion pump 42 pumps the cleaning liquid in the first chamber 201 into the second chamber 202, so that the cleaning liquid in the first chamber 201 cleans the second chamber 202 under high pressure conditions; wherein, the third preset height is higher than the height of the first end of the diversion tube 41, and during this process, the second chamber 202 is in a state of being isolated from the external environment.
