The contradiction of insufficient land, energy, and mineral resources is becoming more acute, and environmental pressure is increasing. Promoting resource recycling has become an urgent task. Generally, during civil engineering construction or tunnel boring machine construction, the engineering mud and waste mud generated need to undergo a series of treatments to produce qualified materials that can be used for road construction. Solving the mud treatment problem and improving resource utilization rate is crucial. A key technical parameter in mud treatment is the density during the treatment process. However, traditionally, the density of mud slurry is usually tested manually, which is difficult and has low accuracy. Summary of the Invention

[0033] The names of the messages or information exchanged between the multiple devices in the embodiments of the present invention are for illustrative purposes only and are not intended to limit the scope of these messages or information.
[0034] See Figures 1 to 4 An embodiment of the present invention provides a slurry density detection device, including a metering assembly 1, a slurry collection assembly 2 for collecting slurry overflowing and discharging from the metering assembly 1, and a system;
[0035] The metering assembly 1 includes a metering frame 11, a weighing cylinder 12 is provided on the metering frame 11, a pull-type load cell 3 is connected between the top of the weighing cylinder 12 and the metering frame 11, and the pull-type load cell 3 is electrically connected to the system.
[0036] The weighing cylinder 12 has a weighing opening 121 at the top and a weighing drain pipe 122 at the bottom. Multiple overflow ports 123 are provided on the side of the weighing cylinder 12 at positions corresponding to the standard capacity. The metering frame 11 is provided with a slurry pipe 13, a clean water pipe 14 and an overflow pipe 15. One end of the slurry pipe 13 and the clean water pipe 14 passes through the weighing opening 121 and is placed inside the weighing cylinder 12. The other end is connected to an external slurry supply pipe and a water supply pipe. One end of the overflow pipe 15 is connected to the overflow port 123, and the other end is connected to the liquid collection assembly 2.
[0037] The system can use a PLC to calculate the slurry density based on the standard capacity of the weighing cylinder 12 and the weight data output by the pull-type weighing sensor 3. The overflow port 123 and the overflow pipe 15 can be connected by the overflow pipe 15 extending into the overflow port 123, or a guide groove can be set on the overflow port 123 to guide the overflowing slurry into the overflow pipe 15.
[0038] Using the above structure, when detecting the slurry density, the pull-type weighing sensor 3 is zeroed, and the slurry to be tested is drawn from the slurry tank by the slurry pump and enters the weighing cylinder 12 through the mud pipe 4. The weighing cylinder 12 contains a standard volume of slurry, and the excess slurry will flow into the liquid collection assembly 2 through the overflow port 123 and the overflow pipe 15. The weight value is displayed by the pull-type weighing sensor 3 to obtain the weight of the slurry, and then the system calculates the accurate slurry density.
[0039] After weighing, the slurry is discharged into the collection assembly 2 through the weighing drain pipe 122 at the bottom of the weighing cylinder 12. It can be returned to the slurry pool or discharged. After the slurry is discharged from the weighing cylinder 12, the weighing cylinder 12 needs to be cleaned to prevent the slurry from adhering to the weighing cylinder 12 and affecting the next test. When cleaning the weighing cylinder 12, clean water is drawn by a clean water pump and enters the weighing cylinder 12 through the clean water pipe 14 to clean the residual slurry inside. The discharged wastewater is discharged through the bottom of the collection assembly 2.
[0040] In one embodiment, see Figure 2 , Figure 3 and Figure 4 A vibrator 16 is provided on the side of the weighing cylinder 12. In practical applications, the vibrator 16 can vibrate the weighing cylinder 12 during material discharge and cleaning, thereby dislodging residual slurry inside the weighing cylinder 12 and improving the cleaning effect of the weighing cylinder 12. This prevents slurry from adhering inside the weighing cylinder 12 and affecting subsequent testing, thus improving the accuracy of subsequent testing.
[0041] The weighing cylinder 12 is composed of a cylindrical section and a conical section. The overflow port 123 is placed in the cylindrical section, and the weighing drain pipe 122 is connected to the cylindrical section, so that the conical section is set between the cylindrical end and the weighing drain pipe 122.
[0042] A first pair of clamp-on pneumatic butterfly valves 124 are installed on the weighing drain pipe 122, and a balance frame 125 is installed on the weighing drain pipe 122. A balance weight 126 is fixed on the balance frame 125. In practical applications, the first pair of clamp-on pneumatic butterfly valves 124 facilitates the control of opening and closing of the weighing drain pipe 122. With the balance frame 125 and the balance weight 126, the first pair of clamp-on pneumatic butterfly valves 124 can be balanced, thereby preventing the weighing cylinder 12 from tilting.
[0043] A support base 127 is provided on the surface of the weighing cylinder 12, and a limit rod 128 is provided at the bottom of the support base 127. A limit frame 111 is provided on the measuring frame 11 at the position corresponding to the support base 127, and a limit hole 112 is provided on the limit frame 111 at the position corresponding to the limit rod 128, through which the limit rod 128 passes. In practical applications, the support base 127 and the limit rod 128, together with the limit hole 112 on the limit frame 111, can limit the vertical direction of the weighing cylinder 12, thereby reducing the tilt of the weighing cylinder 12 and ensuring its horizontality, thus improving the accuracy of density detection. At the same time, during transportation, the limit rod 128 can be fixed to the limit frame 111 by bolts and nuts to prevent the weighing cylinder 12 from shaking during transportation.
[0044] In one embodiment, see Figure 2 and Figure 5 The liquid collection assembly 2 includes a liquid collection frame 21 installed at the bottom of the metering frame 11. A liquid collection tank 22 is installed on the liquid collection frame 21. A liquid collection opening 221 is provided at the top of the liquid collection tank 22, and a liquid collection drain pipe 222 is provided at the bottom. The ends of the weighing drain pipe 122 and the overflow pipe 15 extend into the liquid collection opening 221. A second pair of clamp-on pneumatic butterfly valves 223 are connected to the liquid collection drain pipe 222, and a three-way valve 23 is connected to the bottom of the liquid collection drain pipe 222. In practical applications, the liquid collection tank 22 facilitates the collection of slurry overflowing or discharged from the weighing cylinder 12 through the liquid collection opening 221. It can also be used to collect wastewater after rinsing. With the cooperation of the liquid collection drain pipe 222, the second pair of clamp-on pneumatic butterfly valves 223, and the three-way valve 23, the slurry can be discharged or returned to the slurry pool according to the discharge requirements, or the wastewater can be discharged directly.
[0045] In one embodiment, see Figures 1 to 4 The metering frame 11 has lifting rings 17 at each of its four top corners. In practical applications, the lifting rings 17 facilitate the hoisting of the entire device.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.
[0047] Those skilled in the art should understand that the above embodiments are merely for illustrating the present invention and are not intended to limit the scope of the invention. Those skilled in the art can make other changes or modifications based on the above invention, and these changes or modifications still fall within the scope of the present invention.
