Description

Technical Field

[0001] This utility model relates to the field of grouting equipment technology, specifically a dual-liquid grouting pump with precise flow rate adjustment. Background Technology

[0002] In engineering fields such as construction, water conservancy, and geology, grouting technology is widely used in scenarios such as foundation reinforcement, seepage prevention and plugging, and structural strengthening.

[0003] Currently, dual-liquid grouting is a commonly used grouting method. It involves mixing two different grouts in a certain proportion and injecting them into the target area. The chemical reaction or physical action between the grouts is used to achieve reinforcement, seepage prevention and other effects.

[0004] However, in use, most existing devices can only perform coarse flow control through a single pump body. Insufficient flow regulation accuracy will lead to deviation in the slurry mixing ratio, making it difficult to meet the needs of high-precision grouting operations. Therefore, a dual-liquid grouting pump with precise flow regulation is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, most equipment can only perform coarse flow control through a single pump body. Insufficient flow adjustment accuracy will lead to deviations in the slurry mixing ratio, making it difficult to meet the needs of high-precision grouting operations. This utility model proposes a dual-liquid grouting pump with precise flow adjustment.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a dual-liquid grouting pump with precise flow regulation, comprising a grouting pump body, a base plate provided on the grouting pump body, a main box fixedly connected to the base plate, a fixing plate fixedly connected to the main box, a connecting plate fixedly connected to the middle of the fixing plate, a conduit fixedly connected to the connecting plate, a slurry tank fixedly connected inside the main box, a first connecting pipe fixedly connected to the slurry tank, a main pump fixedly connected inside the main box, the first connecting pipe fixedly connected to the input end of the main pump, a second connecting pipe fixedly connected to the main box, a micro-adjustment pump fixedly connected inside the main box, and the second connecting pipe fixedly connected to the input end of the micro-adjustment pump.

[0007] Preferably, the main pump output end is fixedly connected to a first output pipe, and the first output pipe is fixedly connected to the connecting plate.

[0008] Preferably, the output end of the micro-adjustment pump is fixedly connected to a second output pipe, and the second output pipe is fixedly connected to the connecting plate.

[0009] Preferably, a grouting pump head is fixedly connected to the front end of the conduit, and a monitor is fixedly connected to the middle part of the conduit.

[0010] Preferably, a water tank is fixedly connected to the upper surface of the main tank, and a water outlet pipe is fixedly connected to the water tank. There are two water outlet pipes.

[0011] Preferably, a water pump is fixedly connected to the end of the water outlet pipe, and the water outlet pipe is fixedly connected to the input end of the water pump. Two water pumps are provided.

[0012] Preferably, the output end of the water pump is fixedly connected to a water delivery pipe, the water delivery pipe is fixedly connected to the rear end of the conduit, and a valve is fixedly connected to the conduit.

[0013] The advantages of this utility model are:

[0014] 1. This utility model forms a dual-pump collaborative structure by setting up a main pump and a micro-adjustment pump. The main pump can realize the large-flow slurry delivery, while the micro-adjustment pump can finely adjust the flow rate. The combination of the two can improve the accuracy of flow rate adjustment, meet the strict requirements of different projects for slurry flow rate, and solve the problem that most equipment can only perform coarse flow control through a single pump body. Insufficient flow rate adjustment accuracy will lead to deviation in slurry mixing ratio, making it difficult to meet the needs of high-precision grouting operations.

This utility model uses a cleaning system composed of a water tank, water pump, and water pipe to flush the conduit and other components after the grouting operation, preventing grout residue from clogging the pipes and affecting the accuracy of subsequent grouting, thus improving the convenience of equipment maintenance and service life.
