Description

Technical Field

[0001] This utility model relates to the field of reservoir modification technology, specifically to a foldable automatic stirring device. Background Technology

[0002] Currently, unconventional oil and gas reservoir stimulation often employs large-scale, high-volume fracturing techniques, involving thousands of cubic meters of fracturing fluid and large quantities of chemical additives. To ensure real-time online mixing of the fracturing fluid and smooth operation, all the necessary reagents for a single fracturing stage are typically placed in advance around the mixing truck. During mixing, the reagents from the original tank (1 cubic meter volume) are pumped out separately. However, due to the long operation time and large dosage, stratification and precipitation often occur during real-time extraction. This can lead to changes in reagent concentration, or even prevent pumping altogether, causing blockages in the extraction pipe and rendering the process inoperable. Consequently, the precise dosage addition during real-time mixing cannot be achieved, affecting the performance of the fracturing fluid.

[0003] The existing solution involves manual, handheld electric mixers for real-time mixing. However, due to the small size of the reagent tank's opening and the small size of the handheld mixer, it's impossible to guarantee thorough and uniform mixing of the reagents. Furthermore, this increases manual operating costs, being time-consuming and labor-intensive. Therefore, how to ensure thorough and rapid mixing of the reagents in the tank during construction is a pressing issue that needs to be addressed. Utility Model Content

[0004] The purpose of this invention is to overcome the problem of insufficient mixing caused by the small opening of the container in the prior art, which makes it impossible to fit a stirrer of a suitable size. This invention provides a foldable automatic stirring device with a foldable stirring rod, which can achieve more thorough mixing.

[0005] To achieve the above objectives, this utility model provides a foldable automatic stirring device, including a rotating shaft, a driving component disposed on the top of the rotating shaft, and a stirring assembly disposed on the rotating shaft. The stirring assembly includes a stirring rod hinged to the rotating shaft. The stirring rod is movable between an extended position and a retracted position. In the extended position, the stirring rod extends at an angle to the rotating shaft. In the retracted position, the stirring rod is attached to the rotating shaft.

[0006] Optionally, it also includes a support seat rotatably disposed at the bottom of the rotating shaft.

[0007] Optionally, the stirring assembly further includes an elastic element disposed between the rotating shaft and the stirring rod.

[0008] Optionally, the stirring assembly further includes a first connecting rod and a second connecting rod, the first connecting rod being hinged to the rotating shaft, the second connecting rod being hinged to the stirring rod, and the first connecting rod and the second connecting rod being connected by the elastic element.

[0009] Optionally, the stirring assembly includes a plurality of stirring rods, and the number of stirring assemblies is multiple, with the plurality of stirring assemblies arranged at intervals along the length direction of the rotation axis.

[0010] Optionally, the support base is provided with a bearing, and the bottom of the rotating shaft is disposed within the bearing.

[0011] Optionally, the device may also include a bracket disposed on the drive member, the bracket including a plurality of legs capable of supporting a container of liquid to be stirred.

[0013] Optionally, the support base and the anti-slip pad are made of rubber.

[0014] Optionally, the rotating shaft is provided with a groove to accommodate the stirring rod.

[0018] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0019] This utility model provides a foldable automatic stirring device, including a rotating shaft 1, a driving component 3 disposed on the top of the rotating shaft 1, and a stirring assembly disposed on the rotating shaft 1. The stirring assembly includes a stirring rod 4 hinged to the rotating shaft 1. The stirring rod 4 can move between an extended position and a retracted position. In the extended position, the stirring rod 4 extends at an angle to the rotating shaft 1. In the retracted position, the stirring rod 4 is attached to the rotating shaft 1.

[0020] like Figure 1 As shown, the rotation axis of the stirring rod 4 is perpendicular to the central axis of the rotating shaft 1, so that when the stirring rod 4 is in the retracted position, it can completely fit the rotating shaft 1. The radial dimension of the stirring device in the retracted state is small, which is suitable for various containers with small openings. When the rotating shaft 1 extends into the interior of the container, the stirring rod 4 is opened to be in the extended position. The rotating shaft 1 is driven to rotate by the driving component 3, which in turn drives the stirring rod 4 to rotate, thereby realizing the stirring of the liquid in the container. The length of the stirring rod 4 can be set according to the size of the container so that the stirring area of ​​the stirring rod 4 covers the cross section inside the container as much as possible.

[0021] Through the above technical solution, the stirring rod 4 can be extended or retracted relative to the rotating shaft 1, which can install the stirring device into the container with a small opening without damaging the opening, so as to achieve continuous stirring of the liquid in the container. It is easy to carry and simple to operate, which can effectively reduce labor costs and improve the stirring effect of the liquid in the container.

[0022] Furthermore, the foldable automatic stirring device also includes a support base 2 that is rotatably disposed at the bottom of the rotating shaft 1.

[0023] like Figure 1 As shown, the support base 2 is used to support the stirring device. When the stirring device is placed in the container of the liquid to be stirred, the support base 2 abuts against the bottom surface of the container. The support base 2 can be enlarged as much as possible or its weight can be increased to improve the stability of the stirring device.

[0024] As an optional implementation, the stirring assembly also includes an elastic element 6 disposed between the rotating shaft 1 and the stirring rod 4.

[0025] like Figure 1 As shown, the elastic element 6, such as a spring, tension spring, or sheet metal, can expand the stirring rod 4. The stirring rod 4 is manually pressed back to its retracted position, and then the stirring device is continuously fed into the container. After entering the container, the stirring rod 4 automatically expands under the elastic force of the elastic element 6. In another embodiment, the elastic element 6 may not be provided between the rotating shaft 1 and the stirring rod 4. During rotation, the rotating shaft 1 generates centrifugal force, and the stirring rod 4 automatically spreads outwards under the action of centrifugal force, thereby achieving stirring of the liquid.

[0026] In some embodiments, the stirring assembly further includes a first connecting rod 5 and a second connecting rod 9, the first connecting rod 5 being hinged to the rotating shaft 1 and the second connecting rod 9 being hinged to the stirring rod 4, and the first connecting rod 5 and the second connecting rod 9 being connected by an elastic member 6.

[0027] like Figure 1 As shown, the elastic element 6 can be a tension spring. The first connecting rod 5 and the second connecting rod 9 are connected by the elastic element 6. Under the elastic force of the elastic element 6, the stirring rod 4 can be kept in the open position. Manually operating the stirring rod 4 to rotate to the retracted position can cause the elastic element 6 to extend, increasing the distance between the first connecting rod 5 and the second connecting rod 9, so that the stirring rod 4 can fit against the rotating shaft 1. When installing the stirring device, first manually rotate the stirring rod 4 to the retracted position, and then send the stirring rod 4 into the container to be stirred. When the stirring rod 4 enters the opening of the container, it will automatically open to rotate to the open position.

[0028] Furthermore, the stirring assembly includes multiple stirring rods 4, and the number of stirring assemblies is multiple, with the multiple stirring assemblies arranged at intervals along the length direction of the rotation axis 1.

[0029] like Figure 1 As shown, the more stirring rods 4 there are, the better the stirring effect. The number of stirring rods 4 can be set according to actual needs. In this application, two symmetrically distributed stirring rods 4 are provided. If the container is high, multiple stirring components can be provided. In this application, two stirring components are provided, which can simultaneously stir the liquid located in the upper and lower parts of the container to increase the stirring effect.

[0030] In one embodiment, the support base 2 is provided with a bearing, and the bottom of the rotating shaft 1 is disposed in the bearing.

[0031] like Figure 1 As shown, a bearing is fixedly installed inside the support base 2, and the rotating shaft 1 is fixedly installed in the inner ring of the bearing, which allows the rotating shaft 1 to rotate more smoothly. The rotating shaft 1 and the support base 2 can also adopt other rotating connection methods, such as a gear fixedly installed in the rotating shaft 1, and multiple rotatable gears installed in the support base 2, with the gear at the bottom of the rotating shaft 1 meshing with the gear in the support base 2.

[0032] Furthermore, the foldable automatic stirring device also includes a bracket 7 mounted on the drive unit 3. The bracket 7 includes multiple legs that can support the container of the liquid to be stirred.

[0033] like Figure 1 As shown, the drive component 3 is supported and fixed to the top wall of the container by the bracket 7. The bracket 7 is provided with multiple circumferentially evenly distributed support legs, which can increase the firmness of the drive component 3 and the stability of the stirring device during the stirring process.

[0034] The bottom of the outriggers is equipped with anti-slip pads.

[0035] like Figure 1 As shown, the anti-slip mat 8 can increase the friction between the support leg and the top wall of the container, making the drive component 3 more robust and increasing the stability of the stirring device during the stirring process.

[0036] As an optional implementation, the support base 2 and the anti-slip pad 8 are made of rubber.

[0037] The materials of the support base 2 and the anti-slip pad 8 can be selected according to the material of the container. In this application, the stirring device is used to stir and mix the fracturing fluid. The reagent tank is mostly made of plastic. Therefore, the support base 2 and the anti-slip pad 8 are both made of rubber with a relatively rough surface, which can increase the friction between the support base 2 and the anti-slip pad 8, thereby improving the stability of the stirring device.

[0038] In some embodiments, the rotating shaft 1 is provided with a groove for accommodating the stirring rod 4.

[0039] By providing a groove on the rotating shaft 1, the stirring rod 4 can be embedded into the rotating shaft 1 when it is retracted, which can further reduce the axial dimension of the stirring device. The depth of the groove is preferably set to be greater than the thickness of the stirring rod 4 so that the stirring rod 4 can be completely embedded into the rotating shaft 1, thus making it suitable for containers with small openings.

[0040] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention. These simple modifications and combinations should also be considered as the content disclosed by the present invention and are all within the protection scope of the present invention.

[0041] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0042] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
