Description

Technical Field

[0001] This utility model relates to the field of oilfield additives technology, and in particular to a mixing device for producing clay stabilizers for fracturing. Background Technology

[0002] In oilfield fracturing operations, clay stabilizers are key additives for preventing formation clay expansion, and their production requires thorough mixing via a mixing device. Current technologies often employ traditional mixing devices with a single rotating shaft driving the agitator blades, leading to the formation of vortices along the shaft, uneven mixing, and the tendency for high-density components to settle, affecting product quality. Furthermore, while some mixing devices have attempted to improve performance through dual-shaft or multi-directional mixing, the phenomenon of some raw materials settling to the bottom still occurs.

[0003] Therefore, it is necessary to provide a new mixing device for producing clay stabilizers for fracturing to solve the above-mentioned technical problems. Utility Model Content

A helical gear disk is fixedly mounted on the main rotating shaft. A U-shaped frame is fixedly mounted on the connecting end of the main rotating shaft. A linkage component is mounted on the U-shaped frame. A mixing tank is installed inside the U-shaped frame, and a mixing rod is provided inside the mixing tank.

[0006] Preferably, the linkage component includes a connecting shaft, which is rotatably mounted on a U-shaped frame.

[0013] Compared with related technologies, the mixing device for producing clay stabilizer for fracturing provided by this utility model has the following beneficial effects:

[0014] This invention drives the U-shaped frame and stirring rod to rotate through a linkage component, so that the stirring blades rotate while the mixing tank revolves around the center.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0021] Please see Figures 1 to 3The present invention provides a mixing device for producing clay stabilizer for fracturing, comprising a mounting base 1, a main rotating shaft 2 rotatably connected to the mounting base 1, a helical gear disk 3 fixedly mounted on the main rotating shaft 2, a U-shaped frame 4 fixedly mounted at the connecting end of the main rotating shaft 2, a linkage component 9 mounted on the U-shaped frame 4, a mixing tank 6 installed inside the U-shaped frame 4, and a mixing rod 7 provided inside the mixing tank 6;

[0022] It should be noted that: the raw materials for preparing the clay stabilizer are put into the mixing tank 6, and then the linkage component 9 drives the stirring rod 7 in the mixing tank 6 to rotate, which rapidly stirs the raw materials in the mixing tank 6. At the same time, the U-shaped frame 4 drives the mixing tank 6 to rotate around the main rotating shaft 2. Therefore, the raw materials in the mixing tank 6 are constantly tumbling, which helps to prevent the raw materials from settling to the bottom of the mixing tank 6 during mixing. The stirring blades 8, in conjunction with the rotating mixing tank 6, also solves the common problem in clay stabilizer production where the raw materials follow the rotation of the stirring shaft and stirring blades to form vortices, resulting in poor mixing effect. The linkage component 9 drives the U-shaped frame 4 and stirring rod 7 to rotate, so that the mixing tank 6 revolves around the stirring shaft while the stirring blades 8 rotate on their own axis. The raw materials are subjected to the dual action of centrifugal force and shear force, which makes them mixed evenly and prevents them from settling to the bottom. Furthermore, the rotation of the mixing tank 6 and the counter-movement of the stirring blades 7 break the traditional unidirectional mixing fluid mode, effectively preventing the raw materials from forming vortices with the stirring shaft and improving mixing efficiency.

[0023] See Figures 1 to 3 As shown, the linkage component 9 includes a connecting shaft 91, which is rotatably mounted on the U-shaped frame 4. A helical gear 92 is fixedly mounted at one end of the connecting shaft 91, meshing with the helical gear disc 3. A pulley A 93 is fixedly mounted at the other end of the connecting shaft 91. A pulley B 94 is mounted on the mixing tank 6, and the pulley B 94 is connected to the pulley A 93 via a belt 95. Both ends of the mixing tank 6 are rotatably connected to mounting shafts 5, which are respectively rotatably connected to the inner walls of the two side plates of the U-shaped frame 4. The U-shaped frame 4 is equipped with... The servo motor is fixedly mounted on the U-shaped frame 4 via a frame, and the output end of the servo motor is fixedly connected to the connecting end of pulley A 93 or pulley B 94. Pulley B 94 is fixedly mounted on the mounting shaft 5, which is fixedly connected to the stirring rod 7. The helical gear disk 3 is coaxially arranged with the main rotating shaft 2, and the main rotating shaft 2 passes through the through cavity opened in the center of the helical gear disk 3. The stirring rod 7 is provided with several annularly distributed stirring blades 8, and the stirring rod 7 is fixedly connected to the mounting shaft 5 at one end of the mixing tank 6. The mixing tank 6 is provided with a feed valve 61 and a discharge valve 62 at the top and bottom, respectively.

[0024] It should be noted that: after the servo motor is turned on (in this embodiment, the servo motor is connected to pulley A 93 as an example), and pulley A 93 is rotated, since pulley A 93 and helical gear 92 are fixedly installed on the same connecting shaft 91, the helical gear 92 rotates synchronously, and the helical gear 92 is meshed with the helical gear disk 3, thus driving the mixing tank 6 to rotate around the main rotating shaft 2. The pulley A 93 is also connected to pulley B 94 through belt 95, so the stirring rod 7 can drive the stirring blade 8 to rotate.

[0025] In this embodiment, the helical gear 92 and the helical gear disk 3 are made of surface carburizing hardening treatment or high wear-resistant alloy steel to extend service life and reduce the risk of wear caused by friction due to long-term meshing of the helical gear 92 and the helical gear disk 3, which may affect the transmission accuracy. In addition, technicians can install a protective cover (such as a metal sealing shell) on the outside of the linkage component 9 according to the construction environment or construction technology requirements to prevent dust or foreign objects from entering the gear gap.

[0026] Since the servo motor is directly fixed to the U-shaped frame 4, vibration may affect the overall stability of the equipment. Therefore, technicians can add shock-absorbing pads or flexible couplings between the servo motor and the U-shaped frame 4 as needed to absorb the operating vibration.

[0027] The working principle of the mixing device for producing clay stabilizer for fracturing provided by this utility model is as follows:

[0028] The raw materials for preparing the clay stabilizer are fed into the mixing tank 6 through the feed valve 61. Then, the stirring rod 7 inside the mixing tank 6 is driven to rotate by the linkage component 9. Specifically, after the servo motor (in this embodiment, the servo motor is connected to pulley A 93 as an example) is turned on, the pulley A 93 rotates. Since the pulley A 93 and the helical gear 92 are fixedly installed on the same connecting shaft 91, the helical gear 92 rotates synchronously. The helical gear 92 is meshed with the helical gear disc 3, thus driving the mixing tank 6 to rotate around the main rotating shaft 2. The pulley A 93 is then connected to the main rotating shaft 2. The belt 95 is connected to the pulley 94 for transmission, so the stirring blades 8 on the stirring rod 7 can quickly stir the raw materials in the mixing tank 6. At the same time, the U-shaped frame 4 drives the mixing tank 6 to rotate around the main rotating shaft 2, so the raw materials in the mixing tank 6 are constantly turned over, which helps to prevent the raw materials from settling to the bottom of the mixing tank 6 during mixing. The stirring blades 8 and the rotating mixing tank 6 also solve the common problem that the raw materials will follow the stirring shaft and stirring blades to form a vortex during the mixing of clay stabilizers, resulting in poor mixing effect.

[0029] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
