Description

Technical Field

[0001] The present invention belongs to the technical field of oil extraction, and particularly relates to a cage-type adjustable experimental hanging rack. Background Art

[0002] The high-temperature and high-pressure autoclave is an important experimental equipment for simulating different corrosion conditions in the process of oil and gas extraction. The corrosion experiment of the high-temperature and high-pressure autoclave is usually carried out by fixing the sample on the sample hanging device and then putting it into the autoclave. At present, there are mainly two types of existing sample hanging devices. One is to hang the samples along the inner diameter of the autoclave in turn by using U-shaped clamps, and the other is to use a corrosion rotating cage device. However, with the increasingly complex corrosion environment faced in the exploitation environment and oil and gas treatment process, the simulation conditions of the high-temperature and high-pressure corrosion experiment in the laboratory are also complex and diverse, such as simulating liquid phase environment, gas phase environment, gas-liquid coexistence environment, etc. For the complex corrosion simulation experimental environment, there are different technical defects in the existing two sample hanging methods; among them, the first method has the defect that the surface of the sample is unevenly heated. This is mainly because the existing autoclave is heated by the resistance wire wound around the wall of the autoclave, and there is a temperature gradient from the outer wall of the autoclave to the inside of the autoclave, resulting in uneven temperature distribution at different positions inside the autoclave, and inaccurate corrosion experiment results. The second method is mainly around the thermocouple inside the autoclave. Although it can avoid the problem of uneven heating, the rotating cage often fixes the sample by screws, and thus there is a problem of local crevice corrosion, ultimately reducing the accuracy and reliability of the indoor corrosion experiment results. Summary of the Invention

[0003] The purpose of the present invention is to solve the problems in the prior art, and provides a cage-type adjustable experimental hanging rack.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions to implement:

[0005] A cage-type adjustable experimental hanging rack, comprising: a support member and a mounting member. The support member is of a ring structure, and circular holes are opened on the bottom circumference thereof.

[0006] A bearing member is arranged on the outer side of the connecting member. A first short rod and a second short rod are respectively arranged on both sides of the bearing member, and transverse holes and transverse grooves are respectively opened on the first short rod and the second short rod.

[0007] Further, the bearing member is screwed onto the connecting member, and the included angle between the first short rod and the second short rod on both sides of the bearing member is 120°.

[0008] Further, the cross-section of the transverse groove is U-shaped.

[0032] The present invention will be further described in detail below with reference to the accompanying drawings:

[0033] Such as Figure 1As shown in the figure, an embodiment of the present invention provides a cage-type adjustable experimental hanging rack, which includes: a support member and a mounting member. The support member is a ring-shaped structure, with a hollow bottom and circular holes provided circumferentially. The mounting member is a triangular structure, with a hollow middle part, and mounting holes are provided at its three corners. The circular holes and the mounting holes are fixed through connecting members. A bearing member is provided on the outer side of the connecting member. First short rod 501 and second short rod 502 are respectively provided on both sides of the bearing member. Transverse holes and transverse grooves are respectively provided on the first short rod 501 and the second short rod 502. When hanging a sample, first install the sample support rod 7 on the bearing member. One end of the sample support rod 7 is installed in the transverse hole, and the other end is placed in the transverse groove. A positioning member is provided in the transverse hole, and the positioning member can position the sample support rod 7 on the bearing member. Secondly, wrap the raw tape around the outer side of the sample support rod 7 to insulate the sample from the hanging rack, and sleeve a ceramic washer on the sample support rod 7 to make there be a distance between samples. The distance between the ceramic washer and the sample needs to be greater than 1 mm, which solves the problem of crevice corrosion existing in the existing sample hanging device. Since the sample support rod 7 is installed around the connecting member, the distance between the sample on each sample support rod 7 and the inner wall of the reaction kettle is equal, so each sample can be heated evenly. Compared with the traditional experimental device, when using this hanging rack for experiments, the main body shape is a cylinder, and the bottom is circular, which is convenient for fixing and preventing shaking; the top is triangular, which is convenient for taking and avoiding the obstacles of the kettle lid; the bottom and the top are connected by a connecting member, and the experimental specimens are evenly suspended in a ring along the outer side of the cage-type adjustable hanging rack, and at the same time are close to the heating body on the outer wall of the reaction kettle, which solves the problem of uneven heating of the samples existing in the existing sample hanging device, and the height of the samples can be freely adjusted according to the experimental requirements, fully realizing the position adjustability of the samples in the liquid environment, gas environment and gas-liquid coexistence environment. Secondly, the bearing member can be freely adjusted up and down, which is convenient for measurement and ensures that the samples are horizontally hung. Compared with the traditional method of fixing samples by estimating the liquid level, the accuracy and stability of the sample position are improved; the distance between the sample rows and the inner wall of the kettle is equal, and the heating is uniform, and the accuracy and stability of the experimental results are better;

[0034] In this embodiment, the bearing member is screwed onto the connecting member, and the included angle between the first short rod 501 and the second short rod 502 on both sides of the bearing member is 120°. Specifically, in this embodiment, the connecting member and the bearing member are respectively preferably a through-threaded screw rod 2 and a partial-ear nut 5. The partial-ear nut 5 is screwed on the outer side of the through-threaded screw rod 2. The first short rod 501 and the second short rod 502 are respectively fixedly connected to both sides of the partial-ear nut 5, and the included angle between the two short rods is 120°. Among them, a positioning member is provided on the transverse hole of the first short rod 501, and the positioning member can position the sample support rod 7 on the partial-ear nut 5. The positioning member is preferably a set screw 4. The cross-section of the transverse groove of the second short rod 502 is U-shaped. The U-shaped cross-section can better match the sample support rod 7, and at the same time, it is beneficial to the placement and taking of the samples, with convenient operation and high stability.

[0035] In this embodiment, the middle part of the support member is also a hollow structure. The number of round holes is three, which correspond to the mounting holes one by one. The three round holes are arranged at an angle of 120°. Specifically, the support member is preferably the bottom plate 6, and the bottom plate 6 is used to support the entire hanging rack. The mounting member is preferably the top plate 1, and the top plate 1 and the bottom plate 6 are fixedly connected by a through-threaded screw 2. The number of offset ear nuts 5 on the outside of each through-threaded screw 2 is at least one, such as Figure 1 、 Figure 2 and Figure 3 As shown, the number of offset ear nuts 5 on each through-threaded screw 2 is three. After the sample support rod 7 is installed, the entire hanging rack is a columnar structure.

[0036] In this embodiment, an adjusting member is further provided on the outside of the connecting member. The adjusting member is respectively used to adjust the axial height of the support member, the mounting member and the bearing member on the connecting member. Specifically, since a certain number of samples need to be suspended according to the experimental requirements during the experiment, the number and mounting height of the offset ear nuts 5 need to be adjusted. The adjusting member is preferably a hexagon nut 3, and the number of hexagon nuts 3 on each through-threaded screw 2 is seven.

[0037] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications.
