Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of grouting equipment, in particular to a weighing type grouting system. Background Art
[0002] Grouting refers to pouring a certain proportion (density) of slurry into the pores, cracks of the foundation or the joints and fissures of the building itself at an appropriate pressure to achieve the purpose of filling, anti-seepage and reinforcement. In the grouting process, controlling the slurry concentration is an important link. The grouting process starts with a thin slurry to fill the fine cracks first, and then gradually thickens to fill larger cracks. This way of changing from thin to thick has the best overall grouting quality. Due to the influence of various factors such as geological conditions and different construction volumes during the grouting process, secondary and multiple grouting processes will be involved.
[0003] As the grouting industry places increasingly higher demands on grouting construction quality and control accuracy, the requirements for equipment in the secondary and multiple grouting processes have become increasingly intelligent. The intelligence of grouting processes and controls has put forward higher requirements on grouting systems and equipment.
[0004] At present, the slurry mixing systems commonly used in the industry mainly adopt two measurement methods, namely differential pressure sensor measurement and weighing sensor measurement. The two measurement methods have the following advantages and disadvantages:
[0005] First, differential pressure sensor measurement:
[0006] Advantages: The overall equipment is small in size, easy to transport and arrange on site; the structure is simple and modular in design; the actuators are pneumatically controlled, making them more suitable for harsh environments; the components of each part are easy to install and disassemble.
[0007] Disadvantages: A large number of sensors are used, and maintenance is frequent, and they are susceptible to moisture and damage. Due to the single-layer barrel structure design, the slurry mixing efficiency and slurry storage capacity are weaker than the double-layer barrel structure.
[0008] Second, weighing sensor measurement:
[0009] Advantages: The sensor is not easily damaged and easy to maintain; the double-layer barrel design has better slurry mixing efficiency and storage capacity than the single-layer barrel structure.
[0010] Disadvantages: The overall equipment is large in size, inconvenient to transport and arrange on site; the equipment is highly integrated, and the piping and line layout is complex, making it difficult to find faults and replace related actuators at a later stage. Utility Model Content

DETAILED DESCRIPTION
[0038] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.
[0039] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.
[0040] like Figure 1 and Figure 2As shown, the weighing slurry mixing system of this embodiment includes a frame 3, on which are mounted a weighing slurry mixing barrel 1, a weighing stirring barrel 2, a return slurry barrel, a controller and a stirring device 4, the output end of the stirring device 4 sequentially extends into the weighing slurry mixing barrel 1 and the weighing stirring barrel 2; the bottom of the weighing slurry mixing barrel 1 is connected with a slurry discharge pipe 16 for discharging slurry into the weighing stirring barrel 2, the bottom of the weighing stirring barrel 2 is connected with a stirring barrel slurry discharge pipe 24 for conveying slurry into the holes, and a return slurry barrel for recovering the return slurry in the holes and conveying the return slurry to the weighing stirring barrel 2 is mounted on the frame 3. Among them, the controller is provided with a signal and pneumatic control interface.
[0041] The weighing type slurry mixing barrel 1 of the utility model is used for mixing and storing the slurry from the slurry making station. The weighing type stirring barrel 2 stirs the slurry and then transports it to the pores and cracks of the foundation or the joints and cracks of the building itself to achieve the functions of filling, anti-seepage and reinforcement. The return slurry in the pores and cracks is sent to the return slurry barrel, and then sent to the weighing type stirring barrel 2 by the return slurry barrel, so that the slurry is recycled. The utility model can automatically complete the processes of slurry storage, slurry mixing, stirring, grouting, and return slurry recovery without manual intervention, and each process runs independently without interfering with each other.
[0042] During the grouting process, the weighing grouting barrel 1 and the weighing mixing barrel 2 can measure the slurry quality and liquid level in real time, so as to monitor the density of the slurry in real time, so that the slurry with appropriate density can be poured into the holes. However, due to the influence of factors such as the long grouting pipeline and the change of pipeline pressure, the density of the slurry may change. The return grouting barrel collects the return slurry from the holes during the grouting process, and measures the density of the slurry. The measurement results are fed back to the controller to adjust the grouting ratio and realize feedback adjustment of the slurry density.
[0043] The controller is used to collect signals from weighing sensors, air-isolated density sensors, liquid level sensors and temperature sensors, and at the same time control all pneumatic mechanisms on the grouting system, and finally transmit the collected signals to the control system and pressure regulating system to realize the intelligent grouting process.
[0044] The frame 3 of the weighing grouting system is designed to be triangular in shape, which can reduce the placement area to a greater extent. It is particularly convenient for replacing parts and is more suitable for grouting environments in corridors or where the height of equipment placement is restricted. The triangular structure is stable and uses less material. While reducing costs, it can also reduce the overall equipment weight and facilitate transportation.
[0045] A cycloid pinwheel reducer 42 and a high-power motor are used to ensure the stirring ability of the slurry in the two-layer barrel. The vertical installation method can save lateral space compared to the horizontal installation, and it is more convenient to connect, maintain and replace. The stirring device 4 has a simple appearance and structure, similar to a rectangle. Each steel plate is directly welded, and the structure is stable and not easy to damage. It is installed on the stirring shaft 44 with a screw rod, which is easy to disassemble. The bottom scrapers 47 on the left and right sides of the bottom are assembled at a certain angle and are symmetrical. During the stirring process, it can be ensured that there is no slurry accumulation at the bottom of the barrel, which is more convenient for later cleaning and saves labor.
[0046] Specifically, Figure 3 and Figure 4 As shown, the weighing type slurry mixing barrel 1 includes a slurry mixing tank 11, on which a plurality of slurry mixing tank weighing devices 15 are arranged, the slurry mixing tank weighing devices 15 are installed in the frame 3, a slurry discharge port 110 and a slurry mixing tank sewage discharge port 111 are arranged at the bottom of the slurry mixing tank 11, a slurry discharge pipe 16 is connected to the slurry discharge port 110 of the slurry mixing tank 11, a slurry mixing tank sewage discharge port 111 of the slurry mixing tank 11 is connected to a slurry mixing tank sewage discharge pipe 17, a slurry mixing tank slurry discharge device 13 is installed on the slurry discharge pipe 16, a slurry mixing tank sewage discharge device 14 is installed on the slurry mixing tank sewage discharge pipe 17, and the slurry mixing tank slurry discharge device 13 and the slurry mixing tank sewage discharge device 14 are both electrically connected to the controller. The upper part of the slurry mixing tank 11 is connected to a slurry / clean water filling pipe 18, a slurry mixing tank liquid level measuring device 12 is installed in the slurry mixing tank 11, the output end of the stirring device 4 extends into and passes through the slurry mixing tank 11, and the slurry mixing barrel weighing device 15 and the slurry mixing tank liquid level measuring device 12 are both electrically connected to the controller. A stirring shaft protection tube 19 is fixed in the slurry mixing tank 11, and the stirring shaft 44 of the stirring device 4 is sleeved in the stirring shaft protection tube 19.
[0047] The weighing slurry mixing barrel 1 is also connected with an overflow pipe 112 and a slurry mixing barrel overflow device 113. The function of the overflow pipe 112 is to prevent the slurry from being unable to overflow in time after the slurry mixing tank level measuring device 12 is damaged; when the slurry height reaches the position of the overflow pipe 112, the slurry can be discharged through the overflow pipe 112, thereby preventing the equipment from being stuck with cement. The overflow device 113 is provided with a sewage discharge device. The function of the overflow device 113 is that when it is set to a fixed slurry mixing volume, since the slurry / water inflow into the weighing slurry mixing barrel 1 is dynamic, in order to ensure the accuracy of the slurry mixing parameters, the excess slurry is discharged through its sewage discharge device.
[0048] The slurry mixing tank liquid level measuring device 12 is installed on the outer edge of the slurry mixing tank 11. The probe of the slurry mixing tank liquid level measuring device 12 goes deep into the slurry mixing tank 11, which can detect the liquid level height in the slurry mixing tank 11 in real time, and can be used as an anti-overflow device 113 to prevent the slurry from overflowing out of the tank and damaging the sensor. The slurry discharge and sewage discharge devices are both controlled by pneumatic devices, and both are installed on the bottom of the slurry mixing tank 11 by four bolts. The purpose of the wall-mounted installation is to prevent the slurry from being deposited at the contact parts of the slurry discharge port 110 and the sewage discharge port with the pneumatic device, thereby damaging the pneumatic device. A slurry discharge pipe 16 is installed at the bottom of the slurry discharge device, and the slurry flows into the mixing barrel through the slurry discharge pipe 16. A slurry mixing tank sewage discharge pipe 17 is installed at the bottom of the sewage discharge device, and the waste liquid after the slurry mixing tank is cleaned is directly connected to the sewage discharge funnel 5 through the slurry mixing tank sewage discharge pipe 17. A bend is designed at the tail end of the slurry mixing tank sewage discharge pipe 17 to prevent waste liquid from splashing. The slurry mixing barrel weighing device 15 includes a weighing sensor installed with upper and lower threads and a corresponding protective structure. The position relationship of the three weighing sensors is a circular array. In order to ensure the accuracy and consistency of the measured values, there is an angle of degrees between the two weighing sensors. The slurry / clean water filling pipe 18 is welded to the slurry mixing tank 11 and is at a certain angle to the horizontal direction to facilitate the slurry transmission of the pulping station, and the tail end is designed with a bend pipe like the slurry mixing tank drain pipe 17. The agitator shaft protection pipe 19 is welded to the inside of the slurry mixing tank 11 and is slightly higher than the overflow height of the slurry mixing tank 11 to prevent the slurry from entering the agitator shaft 44.

A longitudinally arranged filtering device 25 is installed in the mixing tank 21, and the mixing barrel slurry outlet pipe 24 and the slurry discharge pipe 16 are arranged on both sides of the filtering device 25. A temperature measuring device 27 is installed on the mixing tank 21.
[0050] The mixing tank liquid level measuring device 22 is installed on the outer edge of the mixing tank 21. The probe of the mixing tank liquid level measuring device 22 goes deep into the mixing tank 21, and can detect the liquid level height in the mixing tank 21 in real time, and can be used as an anti-overflow device 113 to prevent the slurry from overflowing out of the tank and damaging the sensor. The filtering device 25 is installed on the three fixed angle irons inside the mixing barrel, and a gap is left between the fixed angle irons to prevent the phenomenon that the slurry cannot be removed due to excessive grouting for a long time. The mixing barrel slurry outlet pipe 24 and the slurry discharge pipe 16 are respectively arranged on both sides of the filtering device 25 to ensure that the slurry entering the mixing barrel slurry outlet pipe 24 has been filtered. The filtering device 25 adopts a steel wire mesh, which has a firm structure and is easy to clean. The mixing barrel slurry outlet pipe 24 is designed to have a height difference with the bottom of the mixing tank 21, that is, the mixing barrel slurry outlet pipe 24 is lower than the mixing tank 21. The purpose of this design is to prevent the slurry from depositing at the bottom and reduce the work of later cleaning. The temperature measuring device 27 is installed in a threaded manner and is placed below the weighing sensor and slightly higher than the slurry outlet. The protective structure of the weighing device can be used to protect the temperature sensor.

The size of the overflow port 26 is the same as that of the drainage funnel 5, and can fit well with the drainage funnel 5.
[0052] When the slurry ratio does not meet the standard or the equipment needs to be cleaned, the liquid in the weighing slurry mixing barrel 1 is discharged into the drainage funnel 5 through the slurry mixing tank drainage pipe 17, and the liquid in the mixing tank 21 flows into the drainage funnel 5 through the overflow port 26. The return slurry barrel can also automatically discharge the slurry through the drainage funnel 5.

A flexible connection is adopted between the fixed angle irons of the weighing slurry mixing barrel 1, the weighing mixing barrel 2 and the return slurry barrel fixing device and the support frame 31, that is, a mounting hole longer than the angle iron is provided on the support frame 31, and the installation position can be adjusted as needed. At the same time, when replacing the weighing sensor, it can be directly replaced by moving the fixed angle iron up and down.
