Technical Field
[0001] This utility model relates to the field of water pumping technology for calcium carbide slag slurry, and is an automatic water pumping device for calcium carbide slag slurry. Background Technology
[0002] A chemical plant's calcium carbide generator produces a large amount of calcium carbide slurry during the production process. The calcium carbide slurry is temporarily discharged into a storage tank. When the storage tank is full, the slurry needs to be discharged in time for further treatment.
[0003] Currently, the method of pumping water (draining slurry water) into the slurry tank relies on staff observing the tank level. When the tank is nearly full, the pump is started to drain the slurry water. However, this method has the following problems: First, manual operation makes it difficult to accurately control the pumping time and flow rate, leading to unstable slurry water levels in the tank. Sometimes, excessively high levels can cause overflow, affecting the production area environment. Second, frequent manual operation is labor-intensive, prone to errors, affecting equipment operation and increasing the failure rate. In both Phase I and Phase II production units, manual pumping is required approximately 56 times per day, and overflow accidents due to improper tank level control occur monthly. The high equipment failure rate seriously affects the continuity and stability of production.
[0004] In summary, the high labor intensity of pumping water into slurry storage tanks and the unstable liquid level control in the tanks have become urgent technical problems that enterprises need to solve. Summary of the Invention
[0005] This utility model provides an automatic water pumping device for calcium carbide slag slurry, which overcomes the shortcomings of the prior art and can effectively solve the problems of high labor intensity in water pumping and unstable liquid level control in existing calcium carbide slag slurry water storage tanks.

Figure 1 The orientation of the layout is determined by the direction of the map.
[0023] The present invention will be further described below with reference to the embodiments and accompanying drawings:
[0024] Example 1: As shown in the attached document Figure 1 As shown, the automatic water pumping device for calcium carbide slag slurry includes a slurry tank 1, a first slurry output pump 3, a liquid level sensor 4, and a controller. A slurry input trench 5 is provided at the upper inlet of the slurry tank 1. A first slurry output pipeline 6 is fixedly connected to the lower part of the slurry tank 1. The first slurry output pump 3, a first control valve 7, a first pressure gauge 10, and a first flow meter 8 are fixedly installed on the slurry output pipeline 6 along the medium flow direction. A liquid level sensor 4 is provided in the slurry tank 1. The liquid level sensor 4, the first slurry output pump 3, the first control valve 7, the first pressure gauge 10, and the first flow meter 8 are all connected to the controller.
[0025] As needed, the first control valve 7, the first pressure gauge 10, and the controller are interlocked. The first pressure gauge 10 transmits the real-time pressure value of the medium in the first slurry output pipeline 6 at the outlet of the first slurry output pump 3 to the controller. The controller adjusts the opening of the first control valve 7 to maintain the real-time pressure value of the medium in the first slurry output pipeline 6 at the outlet of the first slurry output pump 3 within the allowable pressure value of the process. According to the actual needs of this utility model, when the pressure value displayed by the first pressure gauge 10 is stable at 1.2 MPa, it can ensure that the slurry water in the slurry tank 1 can be smoothly transported to the downstream process system (slurry thickening tank).
[0026] As required, the first slurry output pump 3 is model MHT150-125-400-BK, with a working displacement Q=125m³. 3 / h to 150m 3 The pump has a maximum head of 30m and a rated pressure of 1.6MPa. The first slurry output pump 3, the first flow meter 8, and the controller are interlocked. The first flow meter 8 transmits the real-time flow velocity of the medium in the first slurry output pipeline 6 at the outlet of the first slurry output pump 3 to the controller. The controller adjusts the output power of the first slurry output pump 3 to maintain the flow velocity of the medium in the first slurry output pipeline 6 at the outlet of the first slurry output pump 3 at 125m / h. 3 / h to 150m 3 Between / h.
[0027] The above-mentioned automatic water pumping device for calcium carbide slag slurry can be further optimized and / or improved according to actual needs:
[0028] Example 2: Its difference from Example 1 is as follows: (See attached) Figure 1 As shown, the device also includes a blower 9, a liquid level sensor 4 to collect the real-time liquid level value in the slurry tank 1, the real-time liquid level in the slurry tank 1 includes the minimum liquid level and the overflow liquid level, the air outlet of the blower 9 is fixedly connected to a first air blowing pipeline 12, the outlet of the first air blowing pipeline 12 extends to the minimum liquid level on the left side of the slurry tank 1, and the air inlet of the blower 9 is fixedly connected to an air inlet pipeline 13.
[0029] As required, blower 9 is a Roots blower, model YBX2-160L-4, rated power P=15KW, rated current 31.2A, and total weight G=170Kg.
[0030] As needed, the level sensor 4, the first slurry output pump 3, and the controller are interlocked. When the level sensor 4 detects that the real-time level of the slurry tank 1 has reached the overflow level, the controller increases the output power of the first slurry output pump 3 to quickly pump out the slurry in the slurry tank 1, preventing the slurry in the slurry tank 1 from overflowing. When the level sensor 4 detects that the real-time level of the slurry tank 1 has dropped to the minimum level, the controller can stop the operation of the first slurry output pump 3 to prevent the first slurry output pump 3 from running dry and cavitating.
[0031] Based on the actual volume requirements of slurry tank 1, the controller can set the overflow level of slurry tank 1 to 1.7 meters and the minimum level of slurry tank 1 to 0.3 meters.
[0032] Example 3: Its difference from Examples 1 to 2 is as follows: (See attached) Figure 1 As shown, a second air blowing line 14 is fixedly connected to the first air blowing line 12 above the overflow liquid level in the slurry tank 1, and the outlet of the second air blowing line 14 extends to the lowest liquid level on the right side of the slurry tank 1.
[0033] Example 4: Its difference from Examples 1 to 3 is as follows: (See attached) Figure 1 As shown, several third air-blowing pipelines 15 are fixedly connected to the second air-blowing pipeline 14 above the overflow liquid level in the slurry tank 1 at intervals on the left and right. The outlets of the third air-blowing pipelines 15 all extend to the lowest liquid level in the middle of the slurry tank 1.
[0034] As needed, blower 9 blows air or process gas from the upstream process system into the slurry in slurry tank 1 through the first air blowing line 12, the second air blowing line 14, and the third air blowing line 15. This can prevent slurry sedimentation in slurry tank 1 and make the slurry in slurry tank 1 more homogenized.
[0035] Example 5: It differs from Examples 1 to 4 in that, as shown in the appendix... Figure 1 As shown, the first air blowing pipeline 12, the second air blowing pipeline 14, and the third air blowing pipeline 15 below the overflow level in the slurry tank 1 are all corrosion-resistant hoses.
[0036] Depending on the requirements, the slurry contains a large number of corrosive components, and the corrosion-resistant hose can extend the service life of the first air blowing line 12, the second air blowing line 14, and the third air blowing line 15.
[0037] Example 6: Its difference from Examples 1 to 5 is as follows: (See attached) Figure 1 As shown, two fourth air lines 17 are fixedly connected to the first air line 12 between the air outlet of the blower 9 and the second air line 14.
[0038] If needed, when the amount of slurry in the slurry tank 1 is low, the air volume blown out by the blower 9 can be diverted to the fourth air blowing pipeline 17 and input to other devices as needed.
[0039] Example 7: Its difference from Examples 1 to 6 is as follows: (See attached) Figure 1 As shown, the outlet of the slurry input trench 5 is located on the slurry tank 1 above the overflow level, and the inlet of the first slurry output pipeline 6 is fixedly connected to the slurry tank 1 below the lowest level.
[0040] As needed, the outlet of the slurry input trench 5 is located on the slurry pool 1 above the overflow level to prevent the slurry in the slurry pool 1 from flowing back into the slurry input trench 5.
[0041] As needed, the inlet of the first slurry output pipeline 6 is fixedly connected to the slurry tank 1 below the lowest liquid level, which can prevent the first slurry output pump 3 from running dry and cavitating.
[0042] Example 8: It differs from Examples 1 to 7 in that: as shown in the appendix Figure 1 As shown, a second slurry output pipeline 18 is fixedly connected between the inlet of the first slurry output pump 3 and the outlet of the flow meter 8 on the first slurry output pipeline 6. A second slurry output pump 19, a second control valve 20, a second pressure gauge 11, and a second flow meter 21 are fixedly installed on the second slurry output pipeline 18 in sequence along the medium flow direction.
[0043] As required, the second slurry output pump 19 is also model MHT150-125-400-BK, with a working displacement Q=125m³. 3 / h to 150m 3 / h, maximum head H=30m, rated pressure is 1.6MPa.
[0044] Example 9: It differs from Examples 1 to 8 in that: as shown in the appendix Figure 1 As shown, a third control valve 22 is fixedly installed on the first air line 12 and on both fourth air lines 17 between the second fourth air line 17 and the second air line 14 along the medium flow direction of the first air line 12.
[0045] Example 10: It differs from Examples 1 to 9 in that, as shown in the appendix... Figure 1 As shown, the blower 9, the second slurry output pump 19, the second control valve 20, the second pressure gauge 11, the second flow meter 21, and the third control valve 22 are all connected to the controller.
[0046] As needed, the blower 9, the liquid level sensor 4 and the controller are interlocked. The liquid level sensor 4 transmits the real-time liquid level value in the slurry tank 1 to the controller. The controller adjusts the output power of the blower 9 to ensure that sufficient air volume is introduced into the bottom of the slurry in the slurry tank 1, which can prevent the slurry water in the slurry tank 1 from settling.
[0047] As needed, the level sensor 4, the first slurry output pump 3, the second slurry output pump 19 are interlocked with the controller. When the level sensor 4 collects the real-time level value of the slurry tank 1 and it reaches the overflow level value, the controller can simultaneously increase the output power of the first slurry output pump 3 and the second slurry output pump 19 to quickly pump out the slurry liquid in the slurry tank 1 and prevent the slurry liquid in the slurry tank 1 from overflowing out of the tank.
[0048] Depending on the needs, the pipelines and equipment of this automatic water pumping device for calcium carbide slag slurry can also be equipped with conventional valves, thermometers, and pressure gauges known and commonly used in the field. The controller is a PLC controller, and the model of the PLC controller can be GL-FJ-XL01. The Xinhua XDPS6000 DCS control system is installed in the PLC controller.
[0049] After this utility model was put into use, it reduced the labor intensity of pumping water into the calcium carbide slag slurry tank, reduced the failure rate of the pumping equipment, and improved the safety and production efficiency of the enterprise.
[0050] The above technical features constitute various embodiments of the present invention, which have strong adaptability and implementation effect. Unnecessary technical features can be added or removed according to actual needs to meet the needs of different situations.
[0051] The usage process of this utility model is as follows: First, the slurry input pump 2 inputs the calcium carbide slurry water discharged from the upstream process system (calcium carbide generator) into the slurry tank 1 for buffering through the slurry input trench 5; then, the blower 9 blows air or process gas from the upstream process system sequentially through the first air blowing pipeline 12, the second air blowing pipeline 14, and the third air blowing pipeline 15 to the slurry water below the liquid level in the slurry tank 1 to prevent the slurry water in the slurry tank 1 from settling; then, the liquid level sensor 4 transmits the real-time liquid level value of the slurry water in the slurry tank 1 to the controller, and the controller starts the first slurry output pump 3 and the second slurry output pump 19 to pump the slurry water in the slurry tank 1 to the downstream process system for concentration treatment through the first slurry output pipeline 6 and the second slurry output pipeline 18; finally, when the real-time liquid level value of the slurry tank 1 collected by the liquid level sensor 4 drops to the lowest liquid level, the controller stops the operation of the blower 9, the first slurry output pump 3, and the second slurry output pump 19.
