Description

Technical Field

[0001] The present application relates to the field of automatic control technology, and specifically discloses a device capable of automatically controlling the grouting amount according to pressure. Background Art

[0002] Grouting device is a device used to achieve grouting. At present, grouting technology has been widely used in mining and geotechnical engineering, playing an irreplaceable role in mine grouting filling, tunnel surrounding rock grouting reinforcement, oil field grouting water blocking, highway and airport runway grouting reinforcement, reservoir dam foundation and foundation reinforcement. If the grouting pressure does not meet the design requirements during the grouting process, the grouting effect will be greatly reduced. When the grouting pressure is too high, destructive phenomena such as grouting or surface uplift will occur. Therefore, appropriate grouting pressure is the key to ensuring the grouting effect;

[0003] At present, there is a spring-type pressure control device to achieve automatic pressure control: that is, the internal pressure is too large, causing the spring to compress. When the spring is compressed, the baffle is displaced, the outflow port is exposed, and the slurry flows out. This mode can indeed control the output pressure of the slurry, ensuring that the output pressure of the slurry is large enough, thereby ensuring the grouting effect;

[0004] However, there are certain problems. This pressure-automatic grouting mode cannot be used under high pressure, that is, as long as the work of the spring can be overcome, the grouting liquid can flow out, and the output pressure of the grouting liquid may be uncertain. This pressure-automatic grouting mode will have problems. For some grouting environments, the grouting pressure is required to be within a certain range throughout the process. If there is such a construction requirement, the above-mentioned spring-type pressure-automatic grouting amount device cannot be effectively used. In view of this, the inventor proposes a device that can automatically control the grouting amount according to the pressure. Utility Model Content

[0005] The utility model aims to solve the problem that the traditional automatic pressure control device cannot effectively control the output pressure of the grouting liquid to be output within a certain fixed range.

[0006] In order to achieve the above object, the utility model provides the following basic solutions:

[0007] A device capable of automatically controlling the amount of grouting according to pressure, comprising:

[0008] Adjusting and stabilizing pressure box: the adjusting and stabilizing pressure box is provided with a pressure sensor and a pressure gauge;

[0009] A slurry liquid mixer connected to a regulating pressure stabilizing tank;

[0010] A pressurizer connected to the regulating and stabilizing pressure tank, wherein the pressurizer is electrically connected to the pressure sensor;

[0011] a controller electrically connected to the pressure sensor;

[0012] An electric control output module is connected to the regulating voltage stabilizing box, and the controller is electrically connected to the electric control output module.

[0013] The principles and effects of this basic solution are:

[0014] 1. Compared with the prior art, the device has a simple structure and an ingenious design. The device is provided with an adjusting pressure stabilizing box. The pressure of the adjusting pressure stabilizing box is obtained by a pressure gauge, and the pressure of the adjusting pressure stabilizing box is increased by a pressurizer, so that the internal pressure of the adjusting pressure stabilizing box increases. The increased pressure value is sensed by the pressure sensor, which transmits a corresponding electrical signal to make the electronically controlled output module work. After the electronically controlled output module works, the slurry inside the adjusting pressure stabilizing box will be output at this pressure value. Moreover, due to the output of the slurry inside the adjusting pressure stabilizing box, the pressure begins to decrease. The decreased pressure value is sensed by the pressure sensor, which transmits a corresponding electrical signal to make the electronically controlled output module not work. If the electronically controlled output module does not work, the slurry cannot be output, thereby making the output of the slurry within a range, which finally solves the problem that the traditional automatic pressure control device cannot effectively control the output pressure of the grouting liquid to be output within a fixed range.

[0015] 2. Compared with the prior art, the slurry-liquid mixer is reasonably arranged, and the slurry-liquid mixer realizes the mixing of slurry and slurry, and then realizes pressure change after mixing, which is beneficial to the stability of the slurry.

[0016] Furthermore, the regulating and stabilizing pressure box is also provided with a slurry stirring assembly, which includes an extension box connected to the regulating and stabilizing pressure box, a stirring motor arranged on the top of the extension box, and a stirring frame coaxially connected to the output shaft of the stirring motor, and the stirring frame is placed inside the regulating and stabilizing pressure box.

[0017] Furthermore, the slurry-liquid mixer includes a slurry device and a slurry liquid device, both of which are connected to an extension box, the slurry device includes a slurry hopper, a screw conveyor connected to the slurry hopper, and a drive motor for driving the screw conveyor, and the slurry liquid device includes a slurry hopper, a conduit connected to the slurry hopper, and a booster pump for pressurizing the conduit.

[0018] Furthermore, the pressurizer includes a pressurizing conduit and a pressurizing pump, and the pressurizing conduit is connected to a regulating and stabilizing pressure tank.

[0019] Furthermore, the electrically controlled output module includes an output pipe and an electrically controlled switch valve disposed in the output pipe, the output pipe is connected to a slurry output pipe, and the electrically controlled switch valve is electrically connected to a controller.

[0020] Furthermore, the pressure sensor is provided with two thresholds, which are respectively a maximum threshold and a minimum threshold. The maximum threshold controls the controller to start the electric-controlled switch valve, and the minimum threshold controls the controller to close the electric-controlled switch valve.

[0021] Further, when the lowest threshold control controller closes the electronically controlled switch valve, the pressurizer starts. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Implementation example Figure 1 , Figure 2 and Figure 3 As shown:

[0029] A device capable of automatically controlling the amount of grouting according to pressure, comprising:

[0030] Adjusting the pressure stabilizing box 1: The adjusting pressure stabilizing box 1 is provided with a pressure sensor and a pressure gauge 3;

[0031] A slurry liquid mixer 6 connected to the regulating and stabilizing pressure tank 1;

[0032] Specifically: the regulating and stabilizing pressure box 1 is also provided with a slurry stirring assembly, which includes an extension box 108 connected to the regulating and stabilizing pressure box 1, a stirring motor 109 arranged on the top of the extension box 108 and a stirring frame 110 coaxially connected to the output shaft of the stirring motor 109, and the stirring frame 110 is placed inside the regulating and stabilizing pressure box 1.

[0033] Specifically: the slurry-liquid mixer 6 includes a slurry device and a slurry liquid device, both of which are connected to an extension box 108. The slurry device includes a slurry hopper 105, a screw conveyor 107 connected to the slurry hopper 105, and a drive motor 106 for driving the screw conveyor 107. The slurry liquid device includes a slurry hopper 104, a conduit 102 connected to the slurry hopper 104, and a booster pump 103 for pressurizing the conduit 102.

[0034] The pressurizer 4 connected to the regulating and stabilizing pressure tank 1 is electrically connected to the pressure sensor. The pressurizer 4 includes a pressurizing conduit 401 and a pressurizing pump 402 . The pressurizing conduit 401 is in communication with the regulating and stabilizing pressure tank 1 .

[0035] A controller 2 electrically connected to the pressure sensor;

[0036] The electronically controlled output module 5 is connected to the regulating and stabilizing pressure box 1, and the controller 2 is electrically connected to the electronically controlled output module 5. Specifically, the electronically controlled output module 5 includes an output pipe 501 and an electronically controlled switch valve 502 arranged in the output pipe 501. The output pipe 501 is connected to the slurry output pipe 501, and the electronically controlled switch valve 502 is electrically connected to the controller 2. The pressure sensor is provided with two thresholds, which are the highest threshold and the lowest threshold. The highest threshold controls the controller 2 to start the electronically controlled switch valve 502, and the lowest threshold controls the controller 2 to close the electronically controlled switch valve 502. When the lowest threshold controls the controller 2 to close the electronically controlled switch valve 502, the pressurizer 4 is started.

[0037] Specific implementation process:

[0038] In the first step, the slurry and slurry are inputted by the slurry liquid mixer 6 to form a grouting liquid, and the grouting liquid enters the regulating and stabilizing pressure tank 1, and the slurry stirring component is used to fully stir the grouting liquid;

[0039] The second step is to start the pressurizer 4 to increase the internal pressure of the regulating pressure stabilizing tank 1. The internal pressure of the regulating pressure stabilizing tank 1 gradually rises and reaches the highest threshold of the pressure sensor. At this time, the controller 2 is started to open the electronically controlled switch valve 502, and the grouting liquid flows out.

[0040] The third step is that during the outflow of the grouting liquid, the internal pressure of the pressure regulating box 1 begins to drop and reaches the lowest threshold value of the pressure sensor. At this time, the controller 2 is closed, the electric control switch valve 502 is closed, and the outflow of the grouting liquid stops. After the controller 2 is closed, it serves as an electrical signal to start the pressurizer 4 again, and the highest threshold value of the pressure sensor is reached again, and the grouting liquid is output again, so that the output of the grouting liquid is finally within a specified output pressure range.

[0041] The device solves the problem that the traditional automatic pressure control device cannot effectively control the output pressure of the grouting liquid to be output within a certain fixed range.
