Abstract
Description
Technical Field
[0001] This utility model relates to the field of coal preparation production technology, and in particular to a coal slurry water settling detection system. Background Technology
[0002] In coal preparation plants, wet coal preparation is the mainstream separation process. The coal slurry system is an indispensable part of every wet coal preparation plant. To ensure the rapid settling of the coal slurry generated during washing, reagents are typically added during the coal slurry treatment stage to promote the formation of flocs from fine coal slurry particles and accelerate settling. However, different coal types and different coal slurry properties require different reagent quantities and ratios for settling. To ensure the system's settling effect, it is necessary to monitor the coal slurry properties online and achieve online control of the reagent formulation.
[0003] In production sites, the optimal reagent system for coal slurry is typically determined manually through sampling and dosing experiments. This method lacks representativeness and relies heavily on the experience of staff, compromising the timeliness and accuracy of manual testing. Currently, there is a coal slurry property testing device on the market. This device uses a pump to sample coal slurry from the thickener pipeline into the device's settling pipe. After the settling experiment, the coal slurry is discharged by gravity through a lower discharge valve. However, the application of this type of equipment is limited. Because a certain amount of coal slurry is collected during the experiment, and reagents need to be added during settling, the waste material after the experiment poses a certain environmental hazard. It is only suitable for installation above the thickener and cannot be installed in the workshop or on the ground. Most production sites have environmental protection requirements, therefore, this type of equipment cannot be widely adopted. Utility Model Content

[0040] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0041] It should be noted that in the description of this utility model, the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0042] It should be noted that in the description of this utility model, the terms "connection" and "installation" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or a connection through an intermediate medium; they can refer to a mechanical connection or an electrical connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0043] Because the waste generated after the settling experiment is harmful to the environment and cannot be directly discharged to the outside, the coal slurry water property testing equipment currently on the market is only suitable for installation above the thickener and cannot be installed in the workshop or on the ground. Therefore, this type of equipment cannot be widely promoted.
[0044] Based on this, the present invention provides a coal slurry settling detection system, which is applied to the material conveying pipeline 100 that feeds the material into the thickener, as shown in the reference. Figure 1 The coal slurry settling detection system includes a settling mechanism and a material handling mechanism, wherein:
[0045] The settling mechanism includes a settling pipe 11;
[0046] The material handling and discharging mechanism includes a material handling pipeline assembly 21, a material discharging pipeline assembly 22, and a material handling and discharging pump 23. The material conveying pipeline 100, the material handling pipeline assembly 21, the settling pipe 11, and the material discharging pipeline assembly 22 can be connected end to end to form a closed loop. The material handling and discharging pump 23 is installed on the material handling pipeline assembly 21 and / or the material discharging pipeline assembly 22.
[0047] It should be noted that the discharge pipe assembly 22 can be connected to the middle position of the material conveying pipe 100, or it can be directly connected to the inlet of the thickener. When the discharge pipe assembly 22 is connected to the middle position of the material conveying pipe 100, the waste in the settling pipe 11 is discharged into the material conveying pipe 100 and then enters the thickener through the material conveying pipe 100. When the discharge pipe assembly 22 is directly connected to the inlet of the thickener, the waste in the settling pipe 11 is directly discharged into the thickener.
[0048] The working modes of the above-mentioned coal slurry water settling detection system include pump extraction and gravity discharge mode, gravity extraction and pump extraction and discharge mode, pump extraction and discharge mode, and gravity extraction and discharge mode. Each mode can be switched and adjusted according to the on-site process requirements.
[0049] Reference Figure 2 When the coal slurry settling detection system is in pump extraction and gravity discharge mode, the extraction and discharge pump 23 acts on the extraction pipeline assembly 21. During extraction, the negative pressure generated by the extraction and discharge pump 23 can pump the material in the material conveying pipeline 100 into the settling pipe 11. After the settling experiment is completed, the discharge port at the bottom of the settling pipe 11 is opened, and the waste in the settling pipe 11 is discharged by gravity into the material conveying pipeline 100 or directly into the thickener. This working mode is mainly for production scenarios where the installation location is required and the material in the material conveying pipeline 100 cannot be conveniently sampled by gravity, but the material in the settling pipe 11 can be discharged by gravity.
[0050] Reference Figure 3 When the coal slurry settling detection system is in gravity-feed and pump-discharge mode, the feed pump 23 acts on the discharge pipeline assembly 22. During feed collection, the material in the material conveying pipeline 100 enters the settling pipe 11 by gravity. After the settling experiment is completed, the discharge port at the bottom of the settling pipe 11 is opened, and the feed pump 23 pumps the waste material in the settling pipe 11 into the material conveying pipeline 100 or directly into the thickener. This working mode is mainly for production scenarios where the settling pipe 11 can be installed below the material conveying pipeline 100, and the material in the material conveying pipeline 100 can be conveniently sampled by gravity, but the settling pipe 11 cannot discharge by gravity.
[0051] Reference Figure 4 When the coal slurry settling detection system is in pump extraction and discharge mode, the extraction and discharge pump 23 simultaneously acts on the extraction pipeline assembly 21 and the discharge pipeline assembly 22. During extraction, the negative pressure generated by the extraction and discharge pump 23 pumps the material in the material conveying pipeline 100 into the settling pipe 11. After the settling experiment is completed, the discharge port at the bottom of the settling pipe 11 is opened, and the waste material in the settling pipe 11 is pumped into the material conveying pipeline 100 or directly into the thickener by the negative pressure generated by the extraction and discharge pump 23. This working mode is mainly for production scenarios where the installation location is required, the raw materials for settling detection cannot be conveniently sampled by gravity, and the waste material after settling cannot be discharged by gravity.
[0052] Reference Figure 5When the coal slurry settling detection system is in gravity-flow feeding and discharging mode, during feeding, the material in the material conveying pipeline 100 flows into the settling pipe 11 by gravity. After the settling experiment is completed, the discharge port at the bottom of the settling pipe 11 is opened, and the waste in the settling pipe 11 flows out into the material conveying pipeline 100 by gravity. This working mode is mainly for production scenarios where there are no requirements for the installation location. The settling pipe 11 can be installed below the material conveying pipeline 100 and above the thickener. Thus, the material in the material conveying pipeline 100 can flow into the settling pipe 11 by gravity, and the material in the settling pipe 11 can flow into the material conveying pipeline 100 or the thickener by gravity.
[0053] To avoid material contamination caused by switching pipelines, a circulating material equalization control logic is added to the equipment operation logic to prevent raw material contamination. The specific operation process is as follows: Before each settling test, the discharge port at the bottom of the settling pipe 11 is opened, allowing the material in the material conveying pipeline 100 to be conveyed along the feeding pipeline assembly 21, the settling pipe 11, and the discharge pipeline assembly 22 for a period of time to ensure that there is no material from the previous test in the pipeline. Then, the discharge port at the bottom of the settling pipe 11 is closed, and the material in the material conveying pipeline 100 is sent into the settling pipe 11 for the settling test.
[0054] As described above, the coal slurry settling detection system provided in this application can switch between different working modes for different production scenarios, and can meet the sampling and discharge control requirements under any production process. This enables flexible multi-scenario application of coal slurry property testing equipment, eliminating the need for customized design and manufacturing for different sites, thus enhancing its versatility. Furthermore, the material after the sampling and settling experiment can be discharged into the material conveying pipeline 100 or directly into the thickener using either pumping or gravity flow, achieving closed-loop circulation detection of the coal slurry and preventing environmental pollution.
[0055] Continue to refer to Figure 1 In some embodiments, the material handling pipeline assembly 21 includes a gravity-flow material handling pipeline 211, the upper end of which is connected to the material conveying pipeline 100, and the lower end of which is connected to the settling pipe 11.
[0056] And / or, the material handling pipeline assembly 21 includes a pump extraction pipeline 212, which is connected between the material conveying pipeline 100 and the settling pipe 11, and the material handling pump 23 is disposed on the pump extraction pipeline 212.
[0057] Furthermore, in order to switch between different working modes, both the gravity feed pipeline 211 and the pump feed pipeline 212 are equipped with switching valves.
[0058] In production scenarios where the settling pipe 11 can be installed below the material conveying pipeline 100, the upper and lower ends of the gravity-flow material intake pipeline 211 are connected to the material conveying pipeline 100 and the settling pipe 11, respectively. In this way, the material in the material conveying pipeline 100 can flow naturally into the settling pipe 11 through the gravity-flow material intake pipeline 211 under the action of gravity.
[0059] In production scenarios where the settling pipe 11 cannot be installed below the material conveying pipeline 100, the two ends of the pump extraction pipeline 212 are connected to the material conveying pipeline 100 and the settling pipe 11 respectively. In this way, the material in the material conveying pipeline 100 can be pumped into the settling pipe 11 by the material pump 23 and the pump extraction pipeline 212.
[0060] In some embodiments, the discharge pipeline assembly 22 includes a gravity discharge pipeline 221, the upper end of which is connected to the discharge port at the bottom of the settling pipe 11, and the lower end of which is connected to the material conveying pipeline 100.
[0061] And / or, the discharge pipeline assembly 22 includes a pump discharge pipeline 222, which connects the material conveying pipeline 100 and the discharge port at the bottom of the settling pipe 11, and the discharge pump 23 is installed on the pump discharge pipeline 222.
[0062] Furthermore, in order to switch between different working modes, both the gravity discharge pipeline 221 and the pump discharge pipeline 222 are equipped with switching valves.
[0063] In production scenarios where the settling pipe 11 can be installed above the thickener, the upper and lower ends of the gravity discharge pipe 221 are connected to the discharge port of the settling pipe 11 and the material conveying pipe 100, respectively. In this way, the waste material in the settling pipe 11 can flow naturally into the material conveying pipe 100 through the gravity discharge pipe 221 under the action of gravity.
[0064] In production scenarios where the settling pipe 11 cannot be installed above the thickener, the two ends of the pump discharge pipeline 222 are connected to the discharge port of the settling pipe 11 and the material conveying pipeline 100, respectively. In this way, the waste material in the settling pipe 11 can be pumped into the material conveying pipeline 100 by the pump 23 and the pump discharge pipeline 222.
[0065] Continue to refer to Figure 1The material handling mechanism also includes a waste bin 24 connected between the settling pipe 11 and the discharge pipeline assembly 22. The waste bin 24 is located below the settling pipe 11 so that the waste in the settling pipe 11 can be discharged into the waste bin 24 by gravity. Optionally, the waste bin 24 is connected between the settling pipe 11 and the gravity discharge pipeline 221, and / or, the waste bin 24 is connected between the settling pipe 11 and the pump discharge pipeline 222.
[0066] Figures 1 to 5 In the embodiment shown, the inlet of the waste bin 24 is connected to the discharge port at the bottom of the settling pipe 11, the outlet of the waste bin 24 is connected to the inlet of the pump discharge pipeline 222, and a waste bin feed switch valve 25 is provided on the pipeline between the inlet of the waste bin 24 and the discharge port of the settling pipe 11. Figure 6 In the illustrated embodiment, the inlet of the waste bin 24 is connected to the discharge port at the bottom of the settling pipe 11. The waste bin 24 has two outlets, one connected to the inlet of the gravity discharge pipe 221 and the other to the inlet of the pump discharge pipe 222. The waste bin 24 can buffer waste liquid during the settling detection process. In production scenarios where it is inconvenient to discharge waste externally, the waste can be temporarily stored in the waste bin 24.
[0067] Based on the above structure, a level gauge is installed on the waste bin 24. In the embodiment where the waste bin 24 is connected to the pump discharge pipeline 222, the level gauge works in conjunction with the pump discharge pump 23. When the level gauge detects that the liquid level in the waste bin 24 has reached the set level, the pump discharge pump 23 automatically starts to discharge the waste material, sending the waste material in the waste bin 24 to the material conveying pipeline 100, thereby realizing automatic closed-loop circulation detection of coal slurry water material.
[0068] In this embodiment, as Figure 1 As shown, the material intake pipeline assembly 21 includes a pump intake pipeline 212, and the material discharge pipeline assembly 22 includes a pump discharge pipeline 222. The pump intake pipeline 212 and the pump discharge pipeline 222 have a common pipeline section, and the material intake and discharge pump 23 is installed on the common pipeline section.
[0069] Specifically, the inlet and outlet of the feed pump 23 are connected to the pump extraction pipeline 212 and the pump discharge pipeline 222 simultaneously through a T-joint, respectively. This allows the feed pump 23 to selectively act on the pump extraction pipeline 212 and the pump discharge pipeline 222, effectively reducing the complexity and manufacturing cost of the coal slurry settling detection system, making the system structure simpler and the cost lower.
[0070] To avoid interference between different operating modes, the pump extraction pipeline 212 is equipped with switch valves at both the upstream and downstream of the common pipeline section, and the pump discharge pipeline 222 is equipped with switch valves at both the upstream and downstream of the common pipeline section.
[0071] Specifically, a gravity-flow material intake pipe 211 is equipped with a gravity-flow material intake switch valve 213, a pump extraction material intake pipe 212 is equipped with a pump extraction material intake switch valve one 214 and a pump extraction material intake switch valve two 215 located upstream and downstream of the common pipe section, a gravity-flow material discharge pipe 221 is equipped with a gravity-flow material discharge switch valve 223, and a pump extraction material discharge pipe 222 is equipped with a pump extraction material discharge switch valve one 224 and a pump extraction material discharge switch valve two 225 located upstream and downstream of the common pipe section, respectively.
[0072] In this embodiment, the gravity feeding pipeline 211, the pump extraction pipeline 212, the gravity discharge pipeline 221, and the pump extraction and discharge pipeline 222 are all flexible hoses. During installation, there is no need to consider the interface position of each pipeline, which facilitates the connection of the pipelines.
[0073] The working principle of the coal slurry water settling detection system provided in this embodiment is as follows:
[0074] Reference Figure 2 When the coal slurry settling detection system is in pump extraction and gravity discharge mode, during sampling, pump extraction valve 1 (214) and pump extraction valve 2 (215) are opened, while the other valves are closed. The extraction and discharge pump 23 is started, and the material in the material conveying pipeline 100 enters the settling pipe 11 through the pump extraction pipeline 212. After the settling experiment, the gravity discharge valve 223 is opened, while the other valves are closed. The waste material in the settling pipe 11 enters the material conveying pipeline 100 through the gravity discharge pipeline 221 or directly enters the thickener. This operating mode is mainly for center-driven thickeners, and the coal slurry waste material after sampling and settling can be discharged into the thickener.
[0075] Reference Figure 3 When the coal slurry settling detection system is in gravity-feed and pump-discharge mode, during sampling, gravity-feed switch valve 213 is opened, and the other switch valves are closed. The material in the material conveying pipeline 100 enters the settling pipe 11 through gravity-feed pipeline 211. After the settling experiment, waste discharge switch valve 25 is opened, and the other switch valves are closed. The waste in the settling pipe 11 flows into the waste bin 24 by gravity. This working mode is mainly for peripheral drive thickeners or production scenarios where the coal slurry settling detection system cannot be installed above the thickener. The coal slurry waste after sampling and settling can be temporarily stored in the waste bin 24.
[0076] Reference Figure 4When the coal slurry settling detection system is in pump extraction and discharge mode, during sampling, pump extraction valve 1 (214) and pump extraction valve 2 (215) are opened, while the other valves are closed. The extraction and discharge pump 23 is started, and the material in the material conveying pipeline 100 enters the settling pipe 11 through the pump extraction pipeline 212. After the settling experiment, the waste bin discharge valve 25 is opened, while the other valves are closed, and the waste in the settling pipe 11 flows by gravity into the waste bin 24. This working mode is mainly for production scenarios where the installation location is required, the raw materials for settling detection cannot be conveniently sampled by gravity, and the waste after settling cannot be directly discharged.
[0077] Reference Figure 5 When the coal slurry settling system is in gravity-flow intake and discharge mode, during sampling, gravity-flow intake valve 213 opens while the other valves close. Material in the material conveying pipeline 100 enters the settling pipe 11 through gravity-flow intake valve 213. After the settling experiment, gravity-flow discharge valve 223 opens while the other valves close. Waste in the settling pipe 11 enters the material conveying pipeline 100 through gravity-flow discharge pipeline 221 or directly enters the thickener. This operating mode is primarily for production scenarios where there are no specific requirements for the installation location, allowing for flexible installation of the coal slurry settling system.
[0078] Reference Figure 3 and Figure 4 When the liquid level in the waste tank 24 reaches the set level, the pump discharge switch valve 1 224 and the pump discharge switch valve 225 are opened, the other valves are closed, the discharge pump 23 is started, and the waste in the waste tank 24 enters the material conveying pipeline 100 through the pump discharge pipeline 222 or directly enters the thickener.
[0079] Furthermore, the coal slurry settling detection system provided in this application also includes a processing mechanism for settling analysis of the material in the settling pipe and a cleaning mechanism for cleaning the settling pipe. The processing mechanism includes an online slurry settling monitor, which can detect the settling status in the settling pipe 11 in real time, providing a theoretical basis for actual production. The cleaning mechanism includes a cleaning pipeline, which can be connected to the settling pipe 11 to deliver clean water or cleaning fluid into the settling pipe 11 for rinsing. The structures of the processing mechanism and the cleaning mechanism are basically similar to those of existing settling detection equipment, and their structures will not be described in detail here.
[0080] Furthermore, the settling mechanism, material handling and discharge mechanism, processing mechanism and cleaning mechanism are integrated into the same machine body, which makes the coal slurry settling detection system more complete and can greatly improve the efficiency of on-site installation and commissioning.
[0081] In summary, the coal slurry settling detection system provided in this application integrates material sampling, settling detection, and waste discharge functions. Through the switching and coordination between a single pump, various valves, and pipelines, it can flexibly switch and recombine four working modes: pump sampling, gravity-flow material collection, pump sampling and discharge, and gravity-flow discharge. This can basically meet the sampling and discharge control requirements under any production process. Furthermore, all aspects of the system are centrally designed within a single unit. During on-site installation, only external pipelines for sampling, discharge, air intake, water intake, ventilation, and chemical supply need to be considered, making on-site installation more convenient, significantly reducing equipment debugging difficulty, and avoiding some quality problems caused by installation and construction.
[0082] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
