Description

Technical Field

[0001] This utility model belongs to the field of oilfield chemical instrument technology, and in particular relates to a new type of high-temperature resistant slurry cup assembly for a pressurized thickener. Background Technology

[0002] Currently, commonly used oil well cement slurry high-temperature and high-pressure rheological testing instrument cups and high-temperature and high-pressure thickening instrument cups, both domestically and internationally, are not designed with or equipped with safety pressure relief devices because their initial design only considered the scenario where the oil well cement slurry does not generate a large amount of gas or cause pressure buildup due to gas expansion during the testing process. However, in practical applications, situations frequently arise where the test fluid, such as KQ anti-channeling cement slurry, generates a large amount of gas during the testing process, leading to pressure buildup within the cup and requiring safety pressure relief. Furthermore, traditional slurry cups are difficult to clean after use due to their small internal space, easily leaving residue, and subsequent maintenance is inconvenient. Utility Model Content

[0038] To better understand the purpose, structure, and function of this utility model, a more detailed description of this utility model is provided below with reference to the accompanying drawings.

[0039] See appendix Figures 1-11 As shown, according to some embodiments of this application, it includes:

[0040] The cup body 1 has an internal receiving cavity and openings at the top and bottom;

[0041] It should be noted that the cup body 1 includes: a first arc-shaped body 101 and a second arc-shaped body 102. The first arc-shaped body 101 and the second arc-shaped body 102 are combined to form a receiving cavity with openings at both ends. The top of the first arc-shaped body 101 and the second arc-shaped body 102 are provided with limiting grooves.

[0043] The second capping component 3 is located at the bottom of the cup body 1 and is threadedly connected to the cup body 1.

[0044] The first sealing component 2, the second sealing component 3, and the cup body 1 are combined to form a closed receiving cavity;

[0045] The stirring component 4 is disposed in the receiving cavity. One end of the stirring component 4 passes through the first sealing component 2 and is connected to the driving device. The other end is connected to the second sealing component 3 (the stirring component 4 is supported by the second sealing component 3. A support member 301 is provided at the center of the second sealing component 3. The support member 301 is a block structure. A conical groove is provided at the center of the support member 301. One end of the stirring component 4 is located in the conical groove and can rotate in the conical groove).

[0046] It should be noted that the stirring component 4 is a modular structure, including:

[0047] The stirring shaft 401 has one end passing through the first sealing component 2 into the receiving cavity and connected to the second sealing component 3, and the other end connected to the driving device (such as a drive motor or other device that can drive the stirring shaft 401 to rotate).

[0048] Sleeve 402, the sleeve 402 is provided on the part of the stirring shaft 401 located in the receiving cavity, and the sleeve 402 is detachably fixedly connected to the stirring shaft 401;

[0049] A stirring rack 403 is symmetrically arranged on the sleeve 402 and is fixedly connected to the sleeve 402. A connecting piece 4031 is provided on the stirring rack 403 and is connected to the sleeve 402 through the connecting piece 4031.

[0050] The first stirring blade 404 is arranged in a ring array on the sleeve 402 and is fixedly connected to the sleeve 402. It is located above the connecting piece 4031.

[0051] The second stirring blade 405 is arranged in a ring array on the sleeve 402 and is fixedly connected to the sleeve 402. It is located below the connecting piece 4031.

[0052] It should be further explained that the top corner of the stirring rack 403 has a conical structure, and the connecting plate 4031 of the stirring rack 403, as well as the first stirring blade 404 and the second stirring blade 405, are arranged at an angle.

[0053] Sealing component 5 is disposed between the first sealing component 2 and the cup body 1.

[0054] It should be noted that the sealing component 5 is a modular structure, including:

[0055] The first sealing element 501 has a disc-shaped structure. The first sealing element 501 has a through hole at its center and several raised rings at its bottom. The thickness of the raised rings on the outer side decreases inward. In other words, the raised rings are arranged in a gradient.

[0056] The second sealing element 502 has an annular structure and is located at the bottom of the first sealing element 501. It is fitted into the limiting groove of the first arc-shaped body 101 and the second arc-shaped body 102.

[0057] The third sealing element 503 is a sheet-like structure. The third sealing element 503 is located on the top of the first sealing element 501. It has a through hole at its center and a conical platform at its bottom. The bottom of the conical platform is in contact with the top of the first sealing element 501, and the top of the third sealing element 503 is in contact with the first sealing cover component 2.

[0058] The cup body 1 is composed of two arc-shaped bodies (first and second arc-shaped bodies 102), and a limiting groove is provided at the top to facilitate the installation of multi-layer sealing components 5. The split design simplifies the manufacturing process and facilitates internal cleaning and maintenance, while the modular design improves assembly flexibility, and the limiting groove optimizes the positioning of the sealing components and enhances structural stability.

[0059] The stirring shaft 401 passes through the cup body 1 and is connected to the detachable stirring frame 403 and stirring blades via the sleeve 402. The stirring blades are divided into upper and lower groups, arranged in a ring-shaped inclined manner, with a conical structure at the top corner. The detachable design facilitates the replacement of worn parts. The inclined stirring blades enhance the mixing efficiency of the slurry, and the conical structure reduces resistance and wear.

[0060] The sealing component 5 adopts a multi-layered structure. The thickness of the bottom raised ring of the first seal 501 decreases to accommodate high-temperature deformation. The second seal 502 is embedded in the limiting groove of the cup body 1 to provide a basic seal. The top conical platform of the third seal 503 is in close contact with the cap, forming multiple pressure compensations. The gradient sealing design effectively copes with high-temperature and high-pressure environments and reduces the risk of leakage.

[0061] The technical effects achieved by the above technical solution in the embodiments of this application are as follows:

[0062] The multi-layer seal significantly improves sealing reliability at high temperatures through gradient pressure compensation and raised ring design; the inclined stirring blade and conical stirring frame 403 optimize fluid dynamics, reduce resistance, and improve slurry uniformity; the detachable structure facilitates the replacement of worn parts and extends equipment life; the split cup body 1 and detachable stirring component 4 simplify the disassembly and assembly process, reducing maintenance costs and time; the bottom conical groove and support component 301 design reduces vibration of the stirring shaft 401 and avoids equipment failure caused by eccentricity; through innovative designs such as the split cup body 1, combined stirring component 4, and gradient sealing system, the problems of insufficient sealing, difficult maintenance, and low mixing efficiency of traditional slurry cups under high temperature and high pressure environments are solved.
