Description

Technical Field

[0001] The utility model relates to the technical field of oil production equipment, in particular to a filling device for fracturing construction. Background Art

[0002] Fracturing fluid is a heterogeneous and unstable chemical system formed by a variety of additives in a specific ratio. It is used as a working fluid in the process of oil and gas layer fracturing and transformation, and is one of the effective production and injection measures widely used in oil field exploitation at home and abroad. Hydraulic fracturing, as a common technical means, is inseparable from the important role of fracturing fluid, which has a key impact on improving fracturing effects and oil well productivity.

[0003] However, the existing fracturing fluid mixing equipment stirs the fracturing fluid by setting stirring wings at the bottom of the mixing tank. However, due to the high viscosity of the fracturing fluid and the inappropriate stirring speed, the stirring force on the upper layer of the fracturing fluid is limited, and most of the insoluble matter will be deposited in the lower layer, which may lead to concentration differences between the upper and lower layers of the fracturing fluid, thereby affecting its performance. In view of this, we propose a filling equipment for fracturing construction. Utility Model Content

[0004] The purpose of the utility model is to provide a filling device for fracturing construction to solve the problems raised in the above background technology.

[0005] To achieve the above object, the utility model provides the following technical solution: a filling device for fracturing construction, comprising a stirring tank, a top end surface of the stirring tank is fixedly connected with a feeding port, and a stirring assembly is arranged on the top end surface of the stirring tank, and the stirring assembly comprises:

[0006] A stirring rod, wherein the top end surface of the stirring tank is fixedly connected to a motor, the output end of the motor is fixedly connected to a rotating shaft, and the side wall of the rotating shaft is sleeved with the stirring rod;

[0007] The blades are fixedly connected to a sun gear at one end of the rotating shaft away from the motor, a planetary gear is arranged on the side wall of the sun gear, a flat gear ring is arranged on the outer wall of the planetary gear, a planetary carrier is fixedly connected to the top end face of the planetary gear, and a blade is fixedly connected to the outer wall of the planetary carrier.

[0008] Preferably, a conical gear ring is fixedly connected to the inner wall of the stirring tank, a bevel gear is fixedly connected to the end of the stirring rod away from the rotating shaft, and a stirring blade is fixedly connected to the side wall of the rotating shaft.

[0009] Preferably, a partition is fixedly connected to the inner wall of the stirring tank, a feeding device is fixedly connected to the top end face of the partition, an end of the feeding device away from the partition is socketed with the side wall of the stirring tank, and a control cabinet is fixedly connected to the side wall of the stirring tank.

[0010] Preferably, the flat gear ring is meshed with the planetary gears, and the planetary gears are meshed with the sun gears.

[0011] Preferably, the bottom of the flat gear ring is fixedly connected to the top end surface of the partition, and the flat gear ring does not rotate.

[0012] Preferably, the conical gear ring is meshed with the bevel gear, and when the rotating shaft rotates to drive the bevel gear to rotate along the rotating shaft, the bevel gear and the rotating shaft further rotate horizontally due to the meshing of the conical gear ring and the bevel gear.

[0013] Compared with the prior art, the utility model provides a filling device for fracturing construction, which has the following beneficial effects:

[0014] 1. The filling equipment for fracturing construction is provided with a stirring rod, a sun gear, a planetary gear and a paddle. The stirring rod rotates to stir the fracturing fluid in the upper layer. Since the flat gear ring is fixed, the sun gear and the planetary gear constitute a reduction structure. The rotation speed of the planetary carrier is lower than that of the sun gear, so that the paddle can slowly stir the thicker fracturing fluid at the bottom. At the same time, the paddle is inclined. When the paddle rotates, the fracturing fluid at the bottom can be pushed upward, promoting the fusion of the upper and lower layers of fracturing fluid, and avoiding the difference in concentration between the upper and lower layers of fracturing fluid that affects the performance.

[0015] 2. The filling equipment for fracturing construction is provided with a conical gear ring, a bevel gear and a stirring piece. When the rotating shaft rotates to drive the bevel gear to rotate along the rotating shaft, the conical gear ring is meshed with the bevel gear, so that the bevel gear and the rotating shaft further rotate horizontally, thereby driving the stirring piece to flip and stir the upper and lower fracturing fluids, thereby improving the fusion degree of the fracturing fluid in the stirring tank, and thus improving the performance of the fracturing fluid.

[0022] In one embodiment of the utility model, the top end face of the stirring tank 1 is fixedly connected to a motor 6, the output end of the motor 6 is fixedly connected to a rotating shaft 7, the side wall of the rotating shaft 7 is sleeved with a stirring rod 8, the end of the rotating shaft 7 away from the motor 6 is fixedly connected to a sun gear 9, the side wall of the sun gear 9 is provided with a planetary gear 10, the outer wall of the planetary gear 10 is provided with a flat gear ring 13, the flat gear ring 13 is meshed with the planetary gear 10, the planetary gear 10 is meshed with the sun gear 9, the bottom of the flat gear ring 13 is fixedly connected to the top end face of the partition 3, the flat gear ring 13 will not rotate, and the planetary gear The top end face of 10 is fixedly connected to a planetary carrier 11, the outer wall of the planetary carrier 11 is fixedly connected to a paddle 12, the inner wall of the mixing tank 1 is fixedly connected to a conical gear ring 14, the end of the stirring rod 8 away from the rotating shaft 7 is fixedly connected to a bevel gear 15, the side wall of the rotating shaft 7 is fixedly connected to a stirring blade 16, the outermost side of the stirring blade 16 has no contact with the conical gear ring 14, the conical gear ring 14 is meshed with the bevel gear 15, when the rotating shaft 7 rotates to drive the bevel gear 15 to rotate along the rotating shaft 7, due to the meshing of the conical gear ring 14 and the bevel gear 15, the bevel gear 15 and the rotating shaft 7 further rotate horizontally.

[0023] The fracturing fluid is fed into the mixing tank 1 from the feeding port 2, the motor 6 is started, and the rotating shaft 7 is driven to rotate, and further the stirring rod 8 is driven to rotate, and the stirring rod 8 stirs the fracturing fluid in the upper layer, and then the rotating shaft 7 rotates to drive the sun gear 9 to rotate, and the rotation of the sun gear 9 drives the planetary gear 10 to rotate, and then drives the planetary carrier 11 to rotate. Since the flat ring gear 13 is fixed, the sun gear 9 and the planetary gear 10 form a reduction structure, and the rotation speed of the planetary carrier 11 is lower than that of the sun gear 9, so that the blade 12 can slowly stir the relatively thick fracturing fluid at the bottom, and at the same time, the blade 12 is inclined. When the blade 12 rotates, the fracturing fluid at the bottom can be pushed upward, which promotes the fusion of the upper and lower layers of fracturing fluid and avoids the difference in concentration between the upper and lower layers of fracturing fluid, which affects the performance.

[0024] In addition, a conical gear ring 14 is fixedly connected to the inner wall of the mixing tank 1, and a bevel gear 15 is fixedly connected to the end of the mixing rod 8 away from the rotating shaft 7.

[0025] In the utility model, when in use, the fracturing fluid is put into the mixing tank 1 from the feeding port 2, the motor 6 is started, driving the rotating shaft 7 to rotate, and further driving the stirring rod 8 to rotate. The stirring rod 8 stirs the fracturing fluid in the upper layer, and then the rotating shaft 7 rotates to drive the sun gear 9 to rotate, and the sun gear 9 rotates to drive the planetary gear 10 to rotate, and then drives the planetary carrier 11 to rotate. Since the flat ring gear 13 is fixed, the sun gear 9 and the planetary gear 10 constitute a reduction structure, and the rotation speed of the planetary carrier 11 is lower than that of the sun gear 9, so that the blade 12 can slowly stir the relatively thick fracturing fluid at the bottom. At the same time, the blade 12 is inclined, and when the blade 12 rotates, the fracturing fluid at the bottom can be pushed upward. Further, when the rotating shaft 7 rotates to drive the bevel gear 15 to rotate along the rotating shaft 7, since the conical ring gear 14 is meshed with the bevel gear 15, the bevel gear 15 and the rotating shaft 7 are further rotated horizontally, thereby driving the stirring blade 16 to flip and stir the upper and lower fracturing fluids.
