Description

Technical Field

[0001] The utility model relates to the technical field of coal slurry, in particular to a coal slurry concentration and viscosity monitoring device. Background Art

[0002] This unit uses coal slurry as its raw material. The coal slurry preparation section primarily involves grinding coal, water, and additives in a specific ratio through a coal mill to produce qualified water-coal slurry for delivery to the gasification section. The water-coal slurry section primarily produces qualified water-coal slurry. The concentration and viscosity of the water-coal slurry directly impact the gasifier's operating temperature and the yield of effective synthetic gas. Because the original design lacked remote online monitoring of concentration and viscosity in the water-coal slurry tank, manual sampling and analysis were required onsite during each shift.

[0003] The existing device requires manual sampling and analysis on site during each shift to detect the concentration and viscosity of coal slurry. Sampling is analyzed twice per shift, and the analysis time is about two hours. The serious lag cannot provide timely feedback on the real-time operating status, affecting the operator's judgment and adjustment time, resulting in inaccurate test results. At the same time, due to the high concentration and viscosity of water-coal slurry, it is easy to cause sedimentation over a long period of time, resulting in large errors in the test results. Utility Model Content

[0004] The utility model discloses a coal slurry concentration and viscosity monitoring device, which aims to solve the technical problems that the detection time is long and seriously delayed, affecting the judgment and adjustment time of the operator, and the coal slurry settles due to the long time, resulting in large errors in sampling and laboratory analysis data.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] The transmission gear of the present invention is a gear which is engaged with the gear of the control gear and the gears of the control gear. The gears of the control gear are connected with each other through the gears of the control gear. When the gears of the control gear are engaged with the gear of the control gear, the transmission gears of the control gear are connected with each other through the gears of the control gear. When the gears of the control gear are engaged with the gear of the control gear, the transmission gears of the control gear are connected with each other through the gears of the control gear.

[0007] A coal slurry holding tank, a detection device, a servo motor 1, a linkage gear 1, a linkage gear 2, a driving gear, a screw 1, a screw 2, a coupling and a coal slurry concentration and viscosity detector are provided. By starting the servo motor 1, the driving gear is driven to rotate, and then the driving gear drives the screw 1 and the screw 2 connected to the linkage gear 1 and the linkage gear 2 to rotate, so that the coupling is allowed to reciprocate in the coal slurry holding tank. By adjusting the height of the coal slurry concentration and viscosity detector to adapt to coal slurry detection at different depths, the detection information is remotely transmitted to the control end. In the process, the detection device is directly installed in the coal slurry holding tank, so that the concentration and viscosity of the coal slurry solution can be detected in real time, which is conducive to timely feedback of the real-time operation status of the device and improving the judgment ability of the operator.

[0008] In a preferred embodiment, a stirring mechanism is provided below the coal slurry tank, and the stirring mechanism includes a servo motor 2, and a connecting shaft is fixedly connected to the upper side of the servo motor 2, and the upper side of the connecting shaft is fixedly connected to the lower side of the coal slurry tank. The output end of the servo motor 2 is fixedly connected to a threaded rod, and support plates are movably connected to both sides of the threaded rod, and the upper side of the support plate is fixedly connected to the lower side of the coal slurry tank. A gear plate is provided on the lower side of the coal slurry tank, and the gear plate and the threaded rod are meshed with each other through teeth, and the upper side of the gear plate is movably connected to a rotating frame, and a hole groove is provided at the bottom of the coal slurry tank, and the rotating frame is movably connected to the hole groove, and the upper side of the rotating frame is fixedly connected to a fixed rod, and the upper side of the fixed rod is fixedly connected to a stirring blade.

[0009] By providing a connecting shaft, a second servo motor, a threaded rod, a support plate, a gear plate, a rotating frame, a fixed rod and a stirring blade, when the coal slurry in the coal slurry tank reaches a certain depth, the stirring mechanism is started, and since the threaded rod and the gear plate are engaged with each other through the tooth grooves, the servo motor 2 is started to drive the threaded rod to rotate and at the same time drive the gear plate to rotate, and the rotating frame connected to the gear plate now rotates inside the coal slurry tank, so that the stirring blade stirs the coal slurry in the coal slurry tank. During the process, the stirring mechanism stirs the coal slurry solution to a certain extent, which is beneficial to prevent the coal slurry from settling easily for a long time, reduce the error of the test analysis data, and improve the accuracy of the test results.

[0010] In a preferred solution, a support frame is fixedly connected to the upper side of the coal slurry tank, the upper side of the support frame is fixedly connected to the lower side of the driving gear, and the upper side of the support frame is fixedly connected to a connecting frame, the upper side of the connecting frame is fixedly connected to the lower side of servo motor 2, the outer wall of the coal slurry tank is fixedly connected to a fixing frame, and the lower side of the fixing frame is fixedly connected to multiple shock absorbers.

[0011] By providing a fixing frame, a shock absorber, a support frame and a connecting frame, the support frame and the connecting frame fix the position of the detection equipment, and the fixing frame supports the coal slurry tank so that its stirring mechanism is away from the ground. During the process, the shock absorber connected to the fixing frame can alleviate the vibration effect when encountering vibration, thereby preventing the vibration from affecting the detection results of the detection equipment.

[0012] From the above, it can be seen that the coal slurry concentration and viscosity monitoring device provided by the utility model has the feature of directly installing the detection equipment into the coal slurry tank, which can perform real-time detection of the coal slurry solution, which is conducive to timely feedback of the real-time operating status of the device and improve the judgment ability of the operator. The stirring mechanism stirs the coal slurry solution to a certain extent, which is conducive to preventing the coal slurry from easily causing sedimentation for a long time, reducing the error of the test analysis data, and improving the accuracy of the test results.
