Description

Technical Field

[0001] The utility model belongs to the technical field of grouting reinforcement, and in particular relates to a convenient intelligent controller for slurry flow ratio of a double-liquid / multi-liquid grouting pump. Background Art

[0002] During tunnel excavation, large deformation of tunnel surrounding rock is a major safety hazard in tunnel construction, resulting in multiple re-excavation and rectification issues in some sections of the tunnel. Large deformation of tunnel surrounding rock has become an important constraint on tunnel excavation and use at present and in the future, and is one of the main bottlenecks in tunnel development. The key to managing large deformation of surrounding rock lies in grouting reinforcement of surrounding rock. Dual-liquid or multi-liquid grouting pumps generally cannot accurately control the slurry ratio, which has a great influence on the working performance and mechanical properties of dual-liquid or multi-liquid slurries.

[0003] At present, the stability of double-liquid or multi-liquid grouting is poor. Double-liquid or multi-liquid grouting equipment has problems such as low grouting ratio accuracy, long time to reach the specified ratio, and poor grouting flow stability. Since the grouting equipment fails to mix the grouting materials according to the ratio, the grouting reinforcement effect is poor, affecting safety. In addition, the pressure of the injection press of the two slurries does not match. The pressure of liquid B is too high and enters the pipeline of liquid A, causing the slurry in the liquid A pipe to harden and block the grouting pipe.

[0004] Therefore, it is necessary to provide an improved technical solution to address the above-mentioned deficiencies in the prior art. Utility Model Content

[0028] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0029] According to the specific embodiment of the utility model, Figure 1-2 As shown, the utility model provides a convenient intelligent controller for slurry flow ratio of a dual-liquid / multi-liquid grouting pump. The controller includes multiple groups of control components, and the control components include an intelligent variable frequency valve 4 and an automatic flow detection device 1.

[0030] Each group of control components is arranged at a slurry inlet 51 and a slurry outlet 52 of the grouting pump. Specifically, the intelligent frequency conversion valve 4 in a group of control components is arranged at the A liquid inlet 51 of the grouting pump, and the intelligent frequency conversion valve 4 is used to control the flow rate of the A liquid inlet 51 of the grouting pump.

[0031] An automatic flow detection device 1 in a set of control components is arranged on a pipeline connected to the A liquid outlet 52 of the grouting pump, and the automatic flow detection device 1 is used to detect the slurry flow rate of the A liquid outlet 52 of the grouting pump in real time.

[0032] The real-time detection value of the automatic flow detection device 1 is compared with the set standard value, and the diameter of the intelligent variable frequency valve 4 is adjusted according to the comparison result to adjust the flow of the slurry inlet 51.

[0033] In the dual-liquid / multi-liquid grouting pump slurry flow ratio portable intelligent controller, taking an ordinary dual-liquid grouting pump 5 as an example, the A liquid slurry inlet 51 and the B liquid slurry inlet 51 of the dual-liquid grouting pump 5 are both provided with intelligent variable frequency valves 4, and the B liquid slurry outlet 52 of the dual-liquid grouting pump 5 is provided with a flow automatic detection device 1 on the pipeline connected to the B liquid slurry outlet 52; wherein, after the dual-liquid grouting ratio of A liquid and B liquid and the grouting flow are set, the controller controls the grouting of the A liquid system to reach the set flow, and at the same time, the B liquid system The system adopts follow-up grouting, that is, the A liquid grouting flow rate signal is collected and processed, and grouting is performed according to the set dual-liquid grouting material ratio, and the B liquid grouting flow rate changes with the change of the A liquid grouting flow rate, so as to always ensure that the slurry is injected according to the dual-liquid grouting material ratio. Therefore, without replacing the ordinary dual-liquid grouting pump 5, the dual-liquid / multi-liquid grouting pump slurry flow rate ratio convenient intelligent controller can realize intelligent and precise control of the intelligent grouting of the dual-liquid grouting pump 5. The implementation cost of the controller is low and the control is more precise.

[0034] The controller also includes a data monitoring device 2 , and the plurality of automatic flow detection devices 1 are electrically connected to the data monitoring device 2 . The data monitoring device 2 is used to collect and record detection values ​​of the automatic flow detection devices 1 .

[0035] In one embodiment of the present application, the detection data of multiple automatic flow detection devices 1 are transmitted to the data monitoring device 2, processed by the data monitoring device 2 and transmitted to the downstream programmable logic controller 3.

[0036] The regulator also includes a programmable logic controller 3, and multiple intelligent variable frequency valves 4 are electrically connected to the programmable logic controller 3, and a data monitoring device 2 is electrically connected to the programmable logic controller 3; the data monitoring device 2 is used to transmit the detection value to the programmable logic controller 3, and the programmable logic controller 3 adjusts and controls the diameter size of the intelligent variable frequency valve 4 according to the comparison result between the detection value and the set value.

[0037] In one embodiment of the present application, the programmable logic controller 3 adjusts the flow rate by controlling the intelligent variable frequency valve 4 to change its diameter size; the programmable logic controller 3 sets the program to quickly reach the vicinity of the specified flow value, and then fine-tunes the intelligent variable frequency valve 4 through the signal feedback from the data monitoring device 2 to make it reach the specified flow rate and ratio, thereby achieving precise control of the dual-liquid grouting ratio and shortening the time to reach the specified ratio.

[0038] When the set flow signal is sent, the intelligent variable frequency valve 4 is set according to the judgment of the programmable logic controller 3, and the flow rate of the slurry outlet 52 is detected by the automatic flow detection device 1, and the data detection device is fed back to the programmable logic controller 3. When the flow rate is too large, the slurry inlet diameter of the slurry inlet 51 is reduced to reduce the flow rate of the slurry outlet 52; when the flow rate is too small, the slurry inlet diameter of the slurry inlet 51 is increased to increase the flow rate of the slurry outlet 52.

[0039] The automatic flow detection device 1 is an ultrasonic flow meter, which is installed on a pipeline connected to the grouting pump outlet 52.

[0040] In one embodiment of the present application, the ultrasonic flow meter includes a transmitting unit and a receiving unit. The transmitting unit emits ultrasonic waves to obtain the fluid flow rate when propagating in the flowing fluid. The ultrasonic waves received by the receiving unit can detect the fluid flow rate and thus convert it into flow rate.

[0041] The intelligent variable frequency valve 4 is an automatic flow control valve, which is located at the grouting pump's slurry inlet 51. After receiving a signal from the programmable logic controller 3, the automatic flow control valve adjusts the size of the slurry inlet path to change the flow of the slurry outlet 52.

[0042] The data monitoring device 2 is a flow data collector. In one embodiment of the present application, the flow data collector is used to record the detection data of the automatic flow detection device 1 and feed it back to the programmable logic controller 3.

[0043] The programmable logic controller 3 is a digital operation controller, which is used to change the multi-liquid grouting ratio through programming; and receives the signal sent by the data monitoring device 2 and controls the intelligent variable frequency valve 4.

[0044] When the dual-liquid / multi-liquid grouting pump slurry flow ratio portable intelligent controller is used, the programmable logic editor is set to make the ratio of A and B slurries 1:1. The automatic flow rate detection device is installed on the external pipeline connected to the slurry outlet 52 of the dual-liquid grouting pump 5; the programmable logic controller 3 is installed on the outside of the grouting equipment; the intelligent variable frequency valve 4 is installed at the slurry inlet 51 of the dual-liquid grouting pump 5. Start the controller and the grouting pump, collect the slurry output of A and B slurries respectively, and see if the volume ratio is 1:1. Then use the programmable logic editor to change the ratio of A and B slurries to 3:5, and collect the slurry output of A and B slurries again to see if the volume ratio is 3:5.

[0045] After testing, it was found that the dual-liquid / multi-liquid grouting pump slurry flow ratio portable intelligent controller can accurately control the slurry material ratio. In the presence of programmable logic controller 3, the dual-liquid slurry can be injected in any ratio to enhance the grouting reinforcement effect.

[0046] In summary, the intelligent slurry controller does not need to replace the grouting pump, but installs the controller on the existing basis to shorten the time to reach the specified ratio, improve the stability of the double liquid slurry injection, and significantly improve the accuracy of the double liquid injection ratio. The double liquid slurry can be injected in any ratio, which enhances the grouting reinforcement effect, improves the quality of double liquid grouting, and reduces the consumption of grouting materials. It solves the problems of low grouting ratio accuracy, long time to reach the specified ratio, and poor grouting flow stability of double liquid or multi-liquid grouting equipment.

[0047] It should be understood that the above description is merely exemplary and the embodiments of the present application do not limit this.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are within the scope of protection of the pending claims of the present invention.
