Description

Technical Field

[0001] The present invention relates to the technical field of mud transportation, and in particular to a continuously operating and circulating intelligent mud transportation device and a control method thereof. Background Art

[0002] With the continuous acceleration of urbanization, river dredging has become one of the important tasks in maintaining the urban environment. In the process of river dredging, how to efficiently and safely handle silt has become a key issue, and solving the control efficiency of continuously running intelligent slurry conveying equipment is particularly important.

[0003] The prior art CN205999895U discloses an intelligent mud circulation system with a simple structure, saving manpower and material resources, solving the problem that mud circulation during construction requires a lot of manpower, and realizing long-distance mud transportation, but does not solve the problem of efficiency of continuous mud transportation. Summary of the invention

[0004] To this end, the present invention provides a continuously operating and cyclic intelligent mud conveying equipment and a control method thereof, so as to overcome the problem of low mud conveying efficiency of the mud conveying equipment in the prior art.

[0005] To achieve the above object, the present invention provides a continuously operating and circulating intelligent mud conveying device, comprising:

[0006] A mud extraction pump for extracting mud, including an inlet valve for controlling the inflow of mud;

[0007] A mud conveying mechanism, which is connected to the mud extraction pump and is used to convey the mud, including a mud conveying pipeline providing a mud conveying channel, a mud conveying pump connected to the mud conveying pipeline to provide mud conveying power, and a controller connected to the mud conveying pump to control the start and stop rate;

[0008] A detection mechanism connected to the mud conveying mechanism, comprising a viscometer for detecting the viscosity of the mud and a flowmeter connected to the mud conveying pipeline for detecting the real-time flow of the mud conveying pipeline;

[0009] The control mechanism is respectively connected to the mud extraction pump, the mud conveying mechanism and the detection mechanism, and is used to determine whether the conveying efficiency meets the requirements according to the average flow rate of the mud conveying pipeline. If it is determined that the conveying efficiency does not meet the requirements, the extraction rate of the mud extraction pump is adjusted according to the average flow rate of the mud conveying pipeline, or the fluidity of the mud and the fluidity response method are determined according to the viscosity of the detected mud. The fluidity response method includes reducing the opening of the inlet valve,

[0010] Or, the start and stop rate of the mud delivery pump is initially adjusted, and the start and stop rate of the mud delivery pump is secondarily adjusted according to the change in the average flow rate in the mud delivery pipeline under the condition that the initial adjustment of the start and stop rate is completed.

[0011] Furthermore, the control mechanism is connected to the flow meter and the mud extraction pump respectively to obtain the average flow of the mud conveying pipeline detected by the flow meter, and determine whether the conveying efficiency meets the requirements according to the average flow of the mud conveying pipeline, wherein:

[0012] If the average flow rate of the mud conveying pipeline is less than or equal to a preset second average flow rate, the control mechanism determines that the conveying efficiency does not meet the requirements;

[0013] If the average flow rate of the mud delivery pipeline is less than or equal to a preset first average flow rate, the control mechanism determines to adjust the extraction rate of the mud extraction pump;

[0014] If the average flow rate of the mud conveying pipeline is greater than the preset first average flow rate and less than or equal to the preset second average flow rate, the control mechanism preliminarily determines that the fluidity of the mud does not meet the requirements, and obtains the viscosity of the mud to make a secondary determination of the fluidity of the mud.

[0015] Furthermore, the average flow rate of the mud conveying pipeline is the ratio of the total volume of mud in the mud conveying pipeline collected in a single cycle to the duration of the single cycle.

[0016] Furthermore, the extraction rate of the mud extraction pump is inversely proportional to the average flow rate of the mud delivery pipeline.

[0017] Furthermore, the control mechanism obtains the viscosity of the mud detected by the viscometer to perform a secondary determination on the fluidity of the mud, wherein:

[0018] If the viscosity of the mud is less than or equal to the preset viscosity, the control mechanism determines for the second time that the fluidity of the mud does not meet the requirement.

[0019] Furthermore, the control mechanism is connected to the inlet valve to adjust the opening of the inlet valve according to the viscosity difference of the mud.

[0020] Furthermore, the control mechanism is also connected to a controller of the mud delivery pump to adjust the start and stop rates of the mud delivery pump according to the viscosity difference of the mud.

[0021] Furthermore, the viscosity difference of the mud is the difference between the preset viscosity and the viscosity of the mud.

[0022] Furthermore, after adjusting the start-stop rate, the start-stop rate of the mud delivery pump is adjusted for the second time according to the change in the average flow rate in the mud delivery pipeline, and the start-stop rate after the adjustment is inversely proportional to the start-stop rate before the adjustment.

[0023] Furthermore, the present invention provides a control method for a continuously operating and circulating intelligent mud conveying device, comprising:

[0024] Use a slurry extraction pump to transport the sludge sucked out of the river channel to the location to be tested;

[0025] Determine whether the delivery efficiency meets the requirements based on the average flow rate of the tested delivery pipeline;

[0026] If it is determined that the conveying efficiency does not meet the requirements, the extraction rate of the mud extraction pump is adjusted;

[0027] If the fluidity of the mud is initially determined to be not in compliance with the requirements, a secondary determination is made based on the viscosity of the tested mud to determine whether the fluidity of the mud is in compliance with the requirements;

[0028] If the fluidity of the mud is determined to be unsatisfactory, the opening of the inlet valve is reduced based on the viscosity difference of the mud; or the start and stop rates of the mud pump are adjusted, and after adjusting the start and stop rates, the start and stop rates of the mud pump are adjusted for a second time according to the change in the average flow rate in the pipeline.

[0029] Compared with the prior art, the beneficial effect of the present invention lies in that the present invention includes an inlet valve for controlling the inflow flow of mud through the mud extraction pump; the detection mechanism includes a viscometer for detecting the viscosity of the mud and a flowmeter connected to the mud delivery pipeline for detecting the real-time flow of the mud delivery pipeline; the control mechanism is used to adjust the extraction rate of the mud extraction pump when the delivery efficiency is determined not to meet the requirements according to the average flow of the delivery pipeline, and if the fluidity of the mud is initially determined not to meet the requirements, the fluidity of the mud is secondarily determined to meet the requirements according to the viscosity of the detected mud, including adjusting the opening of the inlet valve or adjusting the start and stop rate of the mud delivery pump. The efficiency of mud delivery is improved, so that the circulation operation of the mud delivery equipment realizes energy saving and environmental protection.

[0030] Furthermore, the present invention obtains the average flow of the mud conveying pipeline by setting a flow meter, thereby overcoming the problem that the conveying efficiency does not meet the requirements due to the real-time flow of the mud conveying pipeline, thereby improving the conveying efficiency of the mud conveying equipment.

[0031] Furthermore, the present invention reduces the extraction rate of the mud pump by providing a mud extraction pump, thereby overcoming the problem that a too high extraction rate of the mud pump may cause the solids and liquids in the mud to separate, thereby causing the mud solids to accumulate in the pipeline and thus resulting in a decrease in the conveying efficiency, thereby achieving zero sedimentation of mud solids and improving the efficiency of mud conveying. Moreover, the reduction in the extraction rate of the mud pump reduces the cost of equipment operation, thereby achieving energy saving and environmental protection of the continuously operating and cyclic intelligent mud conveying equipment.

[0032] Furthermore, the present invention, by setting a control mechanism, can quickly make a secondary judgment on the fluidity of the mud by obtaining the viscosity of the viscometer, thereby overcoming the problem of the fluidity of the mud not meeting the requirements due to the viscosity of the mud not meeting the requirements, thereby achieving unblocked flow of the mud and further improving the efficiency of mud transportation.

[0033] Furthermore, the present invention overcomes the problem of part of the mud gathering inside the mud extraction pump, thereby causing the mud fluidity of the mud extraction pump to decrease, by reducing the opening of the inlet valve. By reducing the opening of the inlet valve, the fluid velocity is increased, which helps to break up the flocculent structure or sediment in the mud, thereby increasing the fluidity and improving the efficiency of mud transportation.

[0034] Furthermore, the present invention achieves the effect of impacting the pipeline by increasing the start and stop rate of the mud delivery pump, so that part of the mud adhering to the pipeline is flushed away, thereby improving the efficiency of mud delivery.

[0035] Furthermore, the present invention reduces the start and stop rate of the mud pump according to the change in the average flow rate in the pipeline, thereby overcoming the problem of unstable connection between the mud pump and the pipeline due to excessive start and stop rate, thereby causing partial water loss and poor fluidity, thereby improving the efficiency of mud transportation.

[0044] See also Figure 1 As shown, it is a structural schematic diagram of a continuously operating and circulating intelligent mud conveying device according to an embodiment of the present invention. The continuously operating and circulating intelligent mud conveying device according to the present invention comprises:

[0045] A mud extraction pump 1, used for extracting mud, including an inlet valve 3 for controlling the inflow flow of mud;

[0046] A mud conveying mechanism, which is connected to the mud extraction pump 1 and is used to convey the mud, comprises a mud conveying pipeline 6 providing a mud conveying channel, a mud conveying pump connected to the mud conveying pipeline 6 and used to provide mud conveying power, and a controller 4 connected to the mud conveying pump and used to control the start and stop rate;

[0047] A detection mechanism, which is connected to the mud conveying mechanism, includes a viscometer 5 for detecting the viscosity of the mud and a flowmeter (not shown in the figure) connected to the mud conveying pipeline for detecting the real-time flow of the mud conveying pipeline;

[0048] The control mechanism is respectively connected to the mud extraction pump 1, the mud conveying mechanism and the detection mechanism, and is used to determine whether the conveying efficiency meets the requirements according to the average flow rate of the mud conveying pipeline. If it is determined that the conveying efficiency does not meet the requirements, the extraction rate of the mud extraction pump is adjusted according to the average flow rate of the mud conveying pipeline, or the fluidity of the mud and the fluidity response method are determined according to the viscosity of the detected mud. The fluidity response method includes reducing the opening of the inlet valve,

[0049] Or, the start and stop rate of the mud delivery pump is initially adjusted, and the start and stop rate of the mud delivery pump is secondarily adjusted according to the change in the average flow rate in the mud delivery pipeline under the condition that the initial adjustment of the start and stop rate is completed.

[0050] See also Figure 2 As shown, it is a flow chart for determining whether the mud conveying efficiency meets the requirements in an embodiment of the present invention. The control mechanism is connected to the flow meter and the mud extraction pump respectively to obtain the average flow of the mud conveying pipeline detected by the flow meter, and determine whether the conveying efficiency meets the requirements according to the average flow of the mud conveying pipeline, wherein:

[0051] If the average flow rate of the mud conveying pipeline is greater than the preset second average flow rate, the control mechanism determines that the conveying efficiency meets the requirements;

[0052] If the average flow rate of the mud delivery pipeline is less than or equal to a preset first average flow rate, the control mechanism determines to adjust the extraction rate of the mud extraction pump;

[0053] If the average flow rate of the mud conveying pipeline is greater than the preset first average flow rate and less than or equal to the preset second average flow rate, the control mechanism preliminarily determines that the fluidity of the mud does not meet the requirements, and obtains the viscosity of the mud to make a secondary determination of the fluidity of the mud.

[0054] Specifically, the average flow rate of the mud conveying pipeline is the ratio of the total volume of mud in the mud conveying pipeline collected in a single cycle to the duration of the single cycle.

[0055] In implementation, a single cycle is 5 minutes, and the average flow rate of the mud conveying pipeline is the ratio of the total volume of mud in the mud conveying pipeline collected within 5 minutes to the 5 minutes.

[0056] In implementation, the preset first average flow rate generally has a value range of [60L / min, 70L / min], and the preset second average flow rate generally has a value range of [80L / min, 90L / min]

[0057] Preferably, the preferred embodiment of the preset first average flow rate is 65 L / min, and the preferred embodiment of the preset second average flow rate is 85 L / min.

[0058] Specifically, the control mechanism is connected to the mud extraction pump, and is also used to adjust the extraction rate of the mud extraction pump when the average flow rate of the mud delivery pipeline is less than or equal to a preset first average flow rate.

[0059] Specifically, in an embodiment, the control mechanism is further used to adjust the extraction rate of the mud extraction pump when the average flow rate of the mud delivery pipeline is less than or equal to a preset first average flow rate, including:

[0060] Recording the ratio of the average flow rate of the mud conveying pipeline to the preset first average flow rate as the flow rate ratio of the mud conveying pipeline;

[0061] If the flow ratio of the mud delivery pipeline is less than or equal to the preset first flow ratio, the control mechanism uses the first extraction rate adjustment coefficient α1 to adjust the extraction rate of the mud extraction pump;

[0062] If the flow rate ratio of the mud delivery pipeline is greater than the preset first flow rate ratio and less than or equal to the preset second flow rate ratio, the control mechanism uses the second extraction rate adjustment coefficient α2 to adjust the extraction rate of the mud extraction pump;

[0063] If the flow ratio of the mud delivery pipeline is greater than the preset second flow ratio, the control mechanism uses the third extraction rate adjustment coefficient α3 to adjust the extraction rate of the mud extraction pump.

[0064] In implementation, the preset first flow ratio is 0.86; the preset second flow ratio is 0.92, and the pumping rate adjustment formula of the mud extraction pump is V=v×αn, wherein V is the pumping rate of the mud extraction pump after adjustment, v is the pumping rate of the mud extraction pump before adjustment, the pumping rate before adjustment is 65L / min, and αn is the nth pumping rate adjustment coefficient, wherein α1=0.98, α2=0.95, α3=0.93, when the ratio of the average flow rate of the mud conveying pipeline to the preset first average flow rate is 0.85, the pumping rate of the mud extraction pump after adjustment is V=v×αn=65×0.98=63.7L / min.

[0065] Specifically, the extraction rate of the mud pump is inversely proportional to the average flow rate of the mud delivery pipeline.

[0066] Specifically, in the embodiment, the extraction rate of the mud pump is reduced because too high an extraction rate of the mud pump may cause the solid and liquid in the mud to separate, thereby causing the mud solid to accumulate in the pipeline, thereby reducing the transportation efficiency.

[0067] See also Figure 3As shown, it is a secondary determination flow chart of whether the fluidity of the mud meets the requirements in an embodiment of the present invention. The control mechanism of the present invention obtains the viscosity of the mud detected by the viscometer to perform a secondary determination on the fluidity of the mud, wherein:

[0068] If the viscosity of the mud is less than or equal to the preset viscosity, the control mechanism determines for the second time that the fluidity of the mud does not meet the requirement.

[0069] In implementation, the control mechanism obtains the viscosity of the mud detected by the viscometer to perform a secondary determination on the fluidity of the mud, wherein:

[0070] If the viscosity of the mud is less than or equal to the preset viscosity, the control mechanism determines for the second time that the fluidity of the mud does not meet the requirement;

[0071] If the viscosity of the mud is greater than the preset viscosity, the control mechanism secondly determines that the start and stop rates of the mud delivery pump do not meet the requirements.

[0072] In practice, the preset viscosity is generally set in the range of [30cps, 45cps].

[0073] Preferably, the preferred embodiment of the preset viscosity is 35 cps.

[0074] Specifically, the control mechanism is connected to the inlet valve, and is also used to adjust the opening of the inlet valve when the viscosity difference of the mud is less than or equal to a preset mud viscosity difference.

[0075] In implementation, the control mechanism is also used to adjust the opening of the inlet valve based on the ratio of the difference in the viscosity of the mud when the difference in the viscosity of the mud is less than or equal to a preset difference in the viscosity of the mud.

[0076] Specifically, in the embodiment, the adjustment process of the mud conveying equipment is determined according to the difference between the viscosity of the mud and the preset mud viscosity, including:

[0077] When the difference in the viscosity of the mud is less than or equal to the preset mud viscosity difference, the reason is that the viscosity is small, resulting in the mud conveying pipeline of the mud conveying equipment adjusting the opening of the inlet valve based on the proportion of the mud viscosity difference.

[0078] Specifically, the control mechanism is also used to adjust the opening of the inlet valve according to the ratio of the viscosity difference of the mud to the preset mud viscosity.

[0079] In the embodiment, the control mechanism is provided with a preset first viscosity difference ratio ΔP1 and a preset second viscosity difference ratio ΔP2, and the process of adjusting the opening of the inlet valve according to the ratio of the viscosity difference of the mud to the preset mud viscosity includes:

[0080] If ΔP≤ΔP1, the control mechanism uses the first inlet valve adjustment coefficient β1 to adjust the inlet opening of the inlet valve to a corresponding value;

[0081] If ΔP1<ΔP≤ΔP2, the control mechanism uses the second inlet valve adjustment coefficient β2 to adjust the inlet opening of the inlet valve to a corresponding value;

[0082] If ΔP>ΔP2, the control mechanism uses the third inlet valve adjustment coefficient β3 to adjust the inlet opening of the inlet valve to a corresponding value.

[0083] In the embodiment, the preset first viscosity difference ratio ΔP1 is 0.08, and the preset second viscosity difference ratio ΔP2 is 0.12. The adjustment formula used in this embodiment is, T = t × βn, where t is 1 square decimeter of the inlet valve area before adjustment, T is the inlet area after adjustment, n is 1, 2, 3, βn is the nth inlet valve adjustment coefficient, and the preferred embodiments of β1, β2 and β3 are: β1 = 1.2; β2 = 1.3; β3 = 1.4; the inlet valve area after adjustment using the first inlet valve adjustment coefficient β1 is T = t × βn, that is, T = 1 × 1.2 = 1.2 square decimeters; the inlet valve area after adjustment is 1.2 square decimeters.

[0084] Specifically, the control mechanism is also connected to the controller of the mud delivery pump to adjust the start and stop rate of the mud delivery pump according to the viscosity difference of the mud;

[0085] Specifically, the adjustment range of the start and stop rate of the mud delivery pump is determined by the ratio of the viscosity difference of the mud to the preset mud viscosity.

[0086] In implementation, the control mechanism is provided with a preset third viscosity difference ratio ΔP3 and a preset fourth viscosity difference ratio ΔP4. The control process of adjusting the start and stop rate of the mud delivery pump according to the difference in the viscosity of the mud and the ratio of the preset mud viscosity includes:

[0087] If ΔP0≤ΔP3, the control mechanism uses the first start-stop rate adjustment coefficient γ1 to adjust the start-stop rate of the mud delivery pump;

[0088] If ΔP3<ΔP0≤ΔP4, the control mechanism uses the second start-stop rate adjustment coefficient γ2 to adjust the start-stop rate of the mud delivery pump;

[0089] If ΔP>ΔP4, the control mechanism uses the third start-stop rate adjustment coefficient γ3 to adjust the start-stop rate of the mud delivery pump;

[0090] Among them, the preset third viscosity difference ratio ΔP3 is 1.02, the preset fourth viscosity difference ratio ΔP4 is 1.05, and the start-stop rate adjustment formula of the mud pump is S=s×γn, wherein s is the start-stop rate of the mud pump before adjustment, and the preset start-stop rate is 80L / min; S is the start-stop rate of the mud pump after adjustment, γn is the nth start-stop rate adjustment coefficient, and the preferred embodiments of γ1, γ2 and γ3 are: γ1=1.02; γ2=1.08; γ3=1.13, respectively. When the ratio of the viscosity difference of the mud to the preset mud viscosity is 1.03, the start-stop rate of the mud pump after adjustment using the second start-stop rate adjustment coefficient γ2 is S=s×γn, that is, S=80×1.08=86.4; the start-stop rate of the mud pump after adjustment is 86.4L / min.

[0091] The present invention achieves the effect of impacting the pipeline by increasing the start and stop rate of the mud delivery pump, so that part of the mud adhering to the pipeline is flushed away, thereby improving the efficiency of mud delivery.

[0092] Specifically, the viscosity difference of the mud is the difference between the preset viscosity and the viscosity of the mud.

[0093] Specifically, after adjusting the start-stop rate, the start-stop rate of the mud delivery pump is adjusted for the second time according to the change in the average flow in the pipeline, and the start-stop rate after the adjustment is inversely proportional to the start-stop rate before the adjustment.

[0094] Specifically, the process of secondary adjusting the start and stop rate of the mud delivery pump according to the change in the average flow rate in the mud delivery pipeline, wherein:

[0095] The change in the average flow rate in the mud conveying pipeline is the difference between the average flow rate in the mud conveying pipeline and the preset average flow rate;

[0096] If the difference between the average flow rate in the mud delivery pipeline and the preset first average flow rate is less than or equal to the preset average flow rate difference, the start and stop rate of the mud delivery pump is reduced using the first rate reduction coefficient λ1;

[0097] If the difference between the average flow rate in the mud delivery pipeline and the preset first average flow rate is greater than the preset average flow rate difference, the second rate reduction coefficient λ2 is used to reduce the start and stop rate of the mud delivery pump.

[0098] In implementation, the preset average flow difference is 5L / min, and the formula for reducing the start and stop rate of the mud pump is W=w×(1+λn) / 2, W is the start and stop rate of the mud pump after adjustment, w is the start and stop rate of the mud pump before adjustment, the preset start and stop rate of the mud pump is 90L / min, λn is the nth rate reduction coefficient, λ1=0.92; λ1=0.88; when the difference between the average flow rate of the mud conveying pipeline and the preset first average flow rate is 3L / min, the start and stop rate of the mud pump is adjusted to W=w×(1+λn) / 2=90×(1+0.88) / 2=84.6L / min.

[0099] The present invention reduces the start and stop rate of the mud delivery pump according to the change of the average flow in the pipeline, thereby overcoming the problem that the connection between the mud delivery pump and the pipeline is unstable due to excessive start and stop rate, thereby causing partial water loss and poor fluidity, and improving the efficiency of mud delivery.

[0100] Please continue reading Figure 4 As shown, it is a flow chart of the steps of the control method of the intelligent mud conveying equipment according to the embodiment of the present invention. The control method of the intelligent mud conveying equipment with continuous operation cycle according to the embodiment of the present invention comprises the following steps:

[0101] Step S1, using a mud extraction pump to transport the sludge sucked out of the river channel to a location to be detected;

[0102] Step S2, determining whether the delivery efficiency meets the requirements according to the average flow rate of the delivery pipeline detected;

[0103] Step S3, if it is determined that the conveying efficiency does not meet the requirements, adjusting the extraction rate of the mud extraction pump;

[0104] Step S4, if it is initially determined that the fluidity of the mud does not meet the requirements, a secondary determination is made based on the viscosity of the detected mud whether the fluidity of the mud meets the requirements;

[0105] Step S5, if the fluidity of the mud is determined to be not in compliance with the requirements, the opening of the inlet valve is reduced based on the viscosity difference of the mud; or the start and stop rates of the mud delivery pump are adjusted, and after the start and stop rates are adjusted, the start and stop rates of the mud delivery pump are adjusted for a second time according to the change in the average flow rate in the pipeline.
