Description

Technical Field

[0001] The utility model relates to a mud production statistical device, in particular to a mud production meter. Background Art

[0002] Mud production meters usually include a flow meter and a seal meter. The flow meter measures the average flow rate of the fluid passing through and multiplies it by the cross-sectional area of the mud pipe to obtain the fluid flow rate. The density meter is used to measure the density of the fluid passing through. The mass of the mud passing through is calculated based on the area and density data.

[0003] Publication No. CN105378439A discloses a flow rate sensor system, including a density or specific gravity meter, a mass flow meter, and a remote processing system. The density or specific gravity meter includes a sensor assembly and density or specific gravity metering electronics configured to generate a density or specific gravity measurement of a process fluid; the mass flow meter includes a sensor assembly and mass flow metering electronics configured to generate a mass flow rate of the process fluid and electrically communicate with the density or specific gravity metering electronics; and the remote processing system is in electrical communication with only one of the density or specific gravity metering electronics or the mass flow metering electronics and is configured to receive a measurement of the process fluid generated by the density or specific gravity metering electronics or the mass flow metering electronics based on the generated density or specific gravity measurement and mass flow rate. The specification also states that the density meter can be an X-ray imaging densitometer or a gamma imaging densitometer.

[0004] In the above-mentioned flow rate sensor system, when detecting the density of the fluid, a radiation source is used to emit radiation to penetrate the tube to detect the density of the fluid in the tube. When the diameter of the tube increases, the amount of radiation that passes through the tube and reaches the detector is lower, resulting in the random effect of radiation decay being too strong at the detector end. The accuracy of density concentration measurement is very poor, and the allowable value of radiation dose is strictly limited. Therefore, the above-mentioned sealing detection cannot be applied to the sealing detection of large-sized tubes. Utility Model Content

[0005] The purpose of the present invention is to overcome the above technical deficiencies and propose a mud production meter to solve the technical problem that the sealing meter in the production statistics device in the prior art cannot measure the density of the fluid in a large-sized pipe.

[0006] In order to achieve the above technical purpose, the present invention adopts the following technical solutions:

[0007] The utility model provides a mud production meter, comprising:

[0008] a tube body, wherein the tube body is formed with a flow channel for fluid to pass through, and one side of the tube body is bulged outward to form a bulge structure; and

[0009] The density detection component includes a radiation source and a detector. The radiation source and the detector are arranged on both sides of the protrusion structure and are used to detect the density of the fluid passing through the protrusion structure.

[0010] In one embodiment, the mud production meter further includes a flow detection component, which is disposed on the pipe body and is used to detect the flow passing through the pipe body.

[0011] In one embodiment, the flow detection component is an electromagnetic flowmeter.

[0012] In one embodiment, the flow detection component is disposed around the tube body and has an opening relative to the radiation source, the detector and the protruding structure. The flow detection component is sleeved on the radiation source, the detector and the protruding structure through the opening.

[0013] In one embodiment, there is a smooth transition between the inner wall of the raised structure and the inner wall of the tube body.

[0014] In one embodiment, the mud production meter further includes an inner liner, wherein the inner liner is attached to and covers the inner wall of the tube body and the raised structure.

[0015] In one embodiment, the raised structure is in an elongated strip shape and is arranged along the length direction of the tube body.

[0016] In one embodiment, the cross-section of the raised structure along the radial direction of the tube body is U-shaped.

[0017] In one embodiment, the radiation dose rate within 500 mm around the radiation source is lower than 0.5 μSv.

[0018] In one embodiment, the mud production meter further includes two flanges, which are respectively provided at two ends of the tube body.

[0019] Compared with the prior art, the mud production meter provided by the present invention has a structure in which the fluid flows through the raised structure when flowing in the pipe body, and the radiation source emits radiation. The radiation passes through the raised structure and enters the pipe body, and is partially absorbed by the raised structure, partially absorbed by the material in the pipe body, and the remaining portion is directed toward the detector. The detector detects the amount of radiation, and calculates the density of the fluid in the pipe body through the amount of radiation, wherein a definite relationship model exists between the amount of radiation and the density of the fluid. Since the radiation only needs to pass through the raised structure, the distance that the radiation penetrates is reduced, so that the sealing detection component can detect the sealing of the fluid in different pipe bodies under the premise of using a radiation source with a small radiation dose, and is suitable for detecting the density of the fluid in pipe bodies with small, medium and large inner diameters. Since a radiation source with a small radiation dose is used, the actual radiation safety risk is small and the acceptance of the staff is high. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0036] In order to solve the technical problem that the sealing meter in the existing production statistics device cannot measure the density of the fluid in the large-sized pipe, the utility model provides a mud production meter that can measure the density of the large-sized pipe without increasing the radiation dose of the radioactive source.

[0037] It should be noted that the mud production meter described in the present invention can be used for measuring the production of mud, and can also be used for measuring the production of solid-liquid mixed fluids such as ore slurry. For the sake of convenience, in the present invention, only the application of the mud production meter device to mud production detection is used as an example for explanation. The principle of applying the mud production meter to other types of equipment is essentially the same as the principle applied to mud production statistics, and will not be repeated here.

[0038] See also Figure 1 , Figure 1 This is a structural schematic diagram of a mud production meter in one embodiment of the present invention. The present invention provides a mud production meter, including a tube body 1 and a density detection assembly 2. The tube body 1 is formed with a flow channel for fluid to pass through, and one side of the tube body 1 is raised outward to form a raised structure 11; the density detection assembly 2 includes a radiation source 21 and a detector 22. The radiation source 21 and the detector 22 are arranged on both sides of the raised structure 11 for detecting the density of the fluid passing through the raised structure 11.

[0039] Specifically, when the fluid flows in the tube body 1, it flows through the raised structure 11, and the radiation source 21 emits radiation. The radiation passes through the raised structure 11 and enters the tube body 1. Part of the radiation is absorbed by the raised structure 11, part is absorbed by the material in the tube body 1, and the other part is emitted to the detector 22. The detector 22 detects the amount of radiation and calculates the density of the fluid in the tube body 1 based on the amount of radiation. There is a definite relationship model between this amount of radiation and the density of the fluid. Since the radiation only needs to pass through the raised structure 11, the distance of radiation penetration is reduced, so that the sealing detection component can detect the sealing of fluids in different tube bodies 1 under the premise of using a radiation source 21 with a small radiation dose, and is suitable for detecting the density of fluids in tube bodies 1 with small, medium and large inner diameters. Since a radiation source 21 with a small radiation dose is used, the actual radiation safety risk is small and the acceptance of staff is high.

[0040] It should be understood that the radiation source 21 and the detector 22 are existing structures, and measuring density using the radiation source 21 and the detector 22 is also an existing technology, which will not be elaborated in this application.

[0041] It should be understood that the radiation emitted by the radiation source 21 may be X-rays, gamma rays, and the like.

[0042] It should be understood that the raised structure 11 is formed by one side of the tube body 1 being raised outward, that is, a bulge formed by one side of the tube body 1 protruding outward, and its wall thickness is the same as that of the tube body 1.

[0043] It should be understood that the pipe body 1 can be a pipe with various cross-sectional shapes.

[0044] like Figures 1 to 3As shown, in one embodiment, the mud production meter further includes a flow detection component 3 , which is disposed on the pipe body 1 and is used to detect the flow passing through the pipe body 1 .

[0045] By setting up a flow detection component 3, the flow detection component 3 can detect the flow through the pipe body 1, obtain the flow velocity of the fluid, and multiply it by the cross-sectional area of the mud pipe to obtain the flow rate of the fluid. The densitometer is used to measure the density of the passing fluid, and the mass of the passing mud is calculated based on the area and density data.

[0046] It should be understood that the flow detection component 3 can be an electromagnetic flowmeter, a turbine flowmeter, an ultrasonic flowmeter, etc. Specifically, in one embodiment, the flow detection component 3 is an electromagnetic flowmeter.

[0047] Since the flow detection component 3 and the sealing detection component are arranged in the same pipe body 1, in order to make the structure compact and avoid the flow detection component 3 blocking the radiation source 21, for this purpose, Figure 1 and Figure 2 As shown, in one embodiment, the flow detection component 3 is arranged around the tube body 1 and has an opening 3a relative to the radiation source 21, the detector 22 and the protrusion structure 11. The flow detection component 3 is sleeved on the radiation source 21, the detector 22 and the protrusion structure 11 through the opening 3a.

[0048] Through the above arrangement, the flow detection component 3 can detect the flow in the tube body 1, and the density detection component 2 can detect the density of the fluid in the tube body 1. Moreover, in the density detection component 2, when the radiation source 21 emits radiation, it will not be blocked by the flow detection component 3.

[0049] like Figure 4 As shown, in one embodiment, the inner wall of the raised structure 11 and the inner wall of the tube body 1 have a smooth transition.

[0050] With the above arrangement, when the fluid flows through the raised structure 11 and the tube body 1 , it can flow along the smoothly transitioned inner wall, thereby reducing the obstruction of the raised structure 11 to the fluid flow.

[0051] Since the slurry such as mud contains particles, it will wear the inner wall of the pipe body 1. For this reason, Figure 4 As shown, in one embodiment, the mud production meter further includes an inner liner 4 , which adheres to and covers the inner wall of the pipe body 1 and the raised structure 11 .

[0052] By arranging the liner 4 in the pipe body 1 and the raised structure 11 , the liner 4 can separate the mud from the pipe body 1 and the raised structure 11 , thereby preventing the mud from directly contacting the inner walls of the pipe body 1 and the raised structure 11 .

[0053] It should be understood that the material of the lining 4 can be polyurethane, polytetrafluoroethylene, polyamide, etc.

[0054] It should be understood that the raised structure 11 can extend along the axial direction and radial direction of the tube body 1. Specifically, Figures 1 to 3 As shown, in one embodiment, the raised structure 11 is in an elongated strip shape and is arranged along the length direction of the tube body 1 .

[0055] The fluid flows inside the tube body 1 along the length of the tube body 1. In this embodiment, the raised structure 11 is long and arranged along the length direction of the tube body 1, so that the flow direction of the fluid in the raised structure 11 is consistent with the flow direction of the fluid in the tube body 1, reducing the obstruction encountered when the fluid flows out and out of the raised structure 11.

[0056] like Figure 4 As shown, in one embodiment, the cross section of the raised structure 11 along the radial direction of the tube body 1 is U-shaped.

[0057] Through the above arrangement, it is possible to avoid the existence of sharp angles in the raised structure 11, thereby preventing the existence of sharp angles that would slow down the flow of the fluid.

[0058] Traditional radiation densitometers using radioactive sources 21 use Class IV to V sources controlled by the national ecological and environmental departments, and require a radiation safety license. They have strict management procedures for pre-approval, in-use supervision, and post-use scrapping. The user's management cost is very high, and due to its high radiation dose, the user's on-site workers are also relatively resistant to this product, so its application is limited in many occasions. For this reason, in one embodiment, the radiation dose rate within 500mm near the radioactive source 21 is less than 0.5μSv.

[0059] The aforementioned radioactive source 21 meets the requirements of GB18871-2002 and is below the exempted dose. This type of radioactive source 21 is registered with the environmental regulatory authorities, and its lifecycle management costs are similar to those of standard instruments. In actual use, the radiation dose rate within 500 mm of the density detection component 2 is already below 0.5 μSv, minimizing the actual radiation safety risk and increasing the acceptance of field workers.

[0060] In order to connect the mud meter with other equipment, such as Figure 1 、 2 , 3 and 5 , in one embodiment, the mud production meter further includes two flanges 5 , which are respectively arranged at both ends of the pipe body 1 .

[0061] When it is necessary to measure the mud production, the mud production meter in this application is set on the conveying path of the mud conveying pipeline and connected to two adjacent mud conveying pipelines through flange 5. By setting flange 5, it is easy to communicate with adjacent pipelines.

[0062] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
