Description

Technical Field

[0001] This utility model relates to the field of dry powder drag-reducing agent preparation technology, and in particular to a dry powder drag-reducing agent preparation device. Background Technology

[0002] Dry powder drag reducers are chemical additives used to reduce fluid flow resistance. They reduce frictional resistance and improve transport efficiency by dispersing in the fluid. Their core function is to alter the fluid's flow behavior through molecular structure, thereby reducing energy consumption. A dry powder drag reducer preparation device is an industrial equipment that mixes the dry powder drag reducer with a fluid (mostly water) to produce a uniform and stable drag-reducing liquid.

[0003] In related technologies, existing dry powder drag-reducing agent preparation devices are mostly stirrers, which use a stirring paddle to mix the dry powder drag-reducing agent with a fluid to produce a drag-reducing liquid. However, in practical applications, the dry powder is often difficult to disperse evenly when it is added to the mixing container through the feeding port. This results in the powder not being able to fully contact the water in the fluid, but instead rapidly accumulating and agglomerating in local areas, gradually forming undissolved hard lumps with swollen surfaces and dry interiors. This leads to uneven concentration distribution of the prepared drag-reducing liquid and reduces the quality of the preparation. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose a dry powder drag-reducing agent preparation device. By adopting a rotary reciprocating feeding structure design, the dry powder drag-reducing agent is evenly added into the preparation tank, which realizes the uniform dispersion of the dry powder drag-reducing agent, avoids the formation of undissolved hard lumps during the mixing process, and improves the preparation quality of the drag-reducing liquid.

[0006] To achieve the above objectives, this utility model proposes a dry powder drag-reducing agent preparation device, including a preparation tank, a fluid conveying pipe, a discharge pipe, a stirring assembly, a feeding assembly, and a homogenizing assembly. The discharge pipe and the fluid conveying pipe are respectively located at the bottom and top of the preparation tank. The stirring assembly is located inside the preparation tank and rotates around its axial direction. The feeding assembly is located on the preparation tank. The homogenizing assembly is rotatably located inside the preparation tank and positioned above the stirring assembly. The outlet of the feeding assembly corresponds to the position of the homogenizing assembly.

[0007] In addition, the dry powder drag-reducing agent preparation device proposed above according to this utility model may also have the following additional technical features: Specifically, the stirring assembly includes a first driving member and a stirring paddle, wherein the first driving member is disposed on the preparation tank and its output shaft is connected to the bottom end of the stirring paddle, and the stirring paddle is rotatably disposed inside the preparation tank.

[0008] Specifically, the feeding assembly includes a feeding hopper, a feeding plate, and a second driving member, wherein the feeding plate is rotatably disposed inside the feeding hopper, the second driving member is disposed on the feeding hopper, and its output shaft is coaxially connected to the feeding plate.

[0009] Specifically, the material leveling assembly includes a third driving component, a connecting shaft, multiple guide rods, an elastic element, a limiting ring, a guide disc, a connecting rod, and a feeding disc. The connecting shaft is mounted on the output shaft of the third driving component. The limiting ring is located at the bottom end of the connecting shaft via multiple guide rods. An elastic element is sleeved on each guide rod. The bottom end of the connecting rod is located on the feeding disc. A guide disc is located at the top end of the connecting rod. The guide disc is slidably mounted on the outer wall of the guide rod, and a driving ring is located above it. The limiting ring is slidably mounted on the connecting rod. The two ends of the elastic element abut against the limiting ring and the guide disc, respectively. The surface edge of the feeding disc has annularly distributed crushing teeth, and the guide disc is uniformly equipped with ball bearings.

[0010] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects: This invention ensures a stable and controllable amount of dry powder entering the preparation tank by setting up a feeding component and rotating to control the conveying amount of dry powder. By setting up a uniform feeding component, the feeding disc can rotate and reciprocate up and down during the addition of the dry powder drag-reducing agent. This, combined with the crushing teeth, crushes and disperses the dry powder, allowing the dry powder drag-reducing agent to be evenly fed into the preparation tank. With the cooperation of the stirring component, it fully contacts the fluid, effectively avoiding the accumulation and clumping of dry powder in local areas and improving the preparation quality of the drag-reducing liquid.

[0014] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0015] The dry powder drag-reducing agent preparation device of this utility model embodiment will be described below with reference to the accompanying drawings.

[0016] like Figures 1-6 As shown, an embodiment of the present invention provides a dry powder drag-reducing agent preparation device, which includes a preparation tank 1, a fluid conveying pipe 2, a discharge pipe 3, a stirring assembly 4, a feeding assembly 5, and a uniform mixing assembly 6, wherein the discharge pipe 3 and the fluid conveying pipe 2 are respectively disposed at the bottom and top of the preparation tank 1.

[0017] It should be noted that the fluid delivery pipe 2 is used to deliver the fluid medium for preparing drag-reducing liquid into the preparation tank 1. A flow valve (not shown in the figure) is installed on the pipe to accurately control the flow rate of the fluid. The discharge pipe 3 is used to discharge the prepared drag-reducing liquid. A valve (not shown in the figure) is installed on the pipe to control the discharge flow rate and opening / closing status.

[0018] The stirring assembly 4 is disposed inside the preparation tank 1 and rotates around the axis of the preparation tank 1.

[0019] It should be noted that the stirring component 4 is used to stir and mix the dry powder drag-reducing agent and fluid in the preparation tank 1 to form a uniform and stable drag-reducing liquid.

[0020] The feeding component 5 is set on the preparation tank 1, and the uniform component 6 is rotatably set inside the preparation tank 1 and located above the stirring component 4. The outlet of the feeding component 5 corresponds to the position of the uniform component 6. It should be noted that the feeding component 5 is responsible for quantitatively and continuously conveying the dry powder drag-reducing agent into the preparation tank 1, while the uniform component 6 disperses and guides the dry powder by rotating, ensuring that the dry powder can fall evenly into the working area of ​​the mixing component 4, and avoiding the dry powder from accumulating and clumping in local areas.

[0021] In one embodiment of this utility model, such as Figure 2 As shown, the stirring assembly 4 includes a first driving member 41 and a stirring paddle 42. The first driving member 41 is disposed on the preparation tank 1, and its output shaft is connected to the bottom end of the stirring paddle 42. The stirring paddle 42 is rotatably disposed inside the preparation tank 1.

[0022] It should be noted that the bearing of the stirring paddle 42 is rotatably connected to the preparation tank 1 through a sealed bearing, which can prevent the drag-reducing liquid from flowing out. The first driving component 41 is a motor, which is fixed to the bottom of the preparation tank 1 through a mounting bracket, and its output shaft is connected to the stirring paddle 42 through a coupling.

[0023] Understandably, when the first drive unit 41 is started, its output shaft drives the stirring paddle 42 to rotate around the axis of the preparation tank 1, thereby fully stirring and mixing the dry powder drag-reducing agent and the fluid in the preparation tank 1, so that the two can be quickly fused together to form a drag-reducing liquid with uniform concentration.

[0024] In one embodiment of this utility model, such as Figure 2 As shown, the feeding assembly 5 includes a feeding hopper 51, a feeding plate 52, and a second driving member 53. The feeding plate 52 is rotatably disposed inside the feeding hopper 51, and the second driving member 53 is disposed on the feeding hopper 51, with its output shaft coaxially connected to the feeding plate 52.

[0025] It should be noted that the feed hopper 51 is installed on the top of the preparation tank 1 and communicates with the preparation tank 1 in order to convey the dry powder drag reducing agent. The feed plate 52 has an integrated shaft in the middle and rotates in the feed hopper 51 through the shaft. The second drive unit 53 is a motor, which is connected to the shaft of the feed plate 52 through a coupling.

[0026] Understandably, when the second drive unit 53 is started, its output shaft drives the feeding plate 52 to rotate in the feed hopper 51. By controlling the rotation speed of the feeding plate 52, the dry powder drag reducer can be quantitatively and continuously conveyed, ensuring that the amount of dry powder entering the preparation tank 1 is stable and controllable.

[0027] In one embodiment of this utility model, such as Figure 3-6 As shown, the material leveling assembly 6 includes a third driving component 61, a connecting shaft 62, multiple guide rods 63, an elastic element 64, a limiting ring 65, a guide disc 68, a connecting rod 69, and a feeding disc 70. The connecting shaft 62 is mounted on the output shaft of the third driving component 61. The limiting ring 65 is mounted on the bottom end of the connecting shaft 62 via multiple guide rods 63. The elastic element 64 is sleeved on the guide rods 63. The bottom end of the connecting rod 69 is mounted on the feeding disc 70. The top end of the connecting rod 69 is mounted on the guide disc 68, which is slidably mounted on the outer wall of the guide rod 63 and has a driving ring 66 mounted above it. The limiting ring 65 is slidably mounted on the connecting rod 69. The two ends of the elastic element 64 abut against the limiting ring 65 and the guide disc 68, respectively.

[0028] It should be noted that the third driving component 61 is a motor, which is mounted on the top of the preparation tank 1 via a mounting bracket and connected to the connecting shaft 62 via a coupling. The connecting shaft 62 is rotatably connected inside the preparation tank 1 via a sealed bearing. The driving ring 66 is fixed to the inner top wall of the preparation tank 1, and its lower surface is provided with a continuous and annularly distributed curved surface. The driving ring 66 contacts the ball 67 on the guide plate 68 through this curved surface. The elastic element 64 is a stainless steel spring, which presses against the guide plate 68 and the limiting ring 65 respectively.

[0029] Specifically, the guide rod 63 and the connecting rod 69 work together to limit the guide plate 68 and the limiting ring 65, ensuring that they can only slide in a straight line in the vertical direction without deflection or shaking.

[0030] The surface edge of the feed plate 70 is provided with crushing teeth 71 arranged in a ring, and the guide plate 68 is uniformly provided with balls 67.

[0031] It should be noted that the feeding plate 70 is evenly provided with feeding holes to uniformly feed the dry powder drag-reducing agent. The crushing teeth 71 can further crush and disperse the agglomerated dry powder. The ball bearings 67 can reduce the friction between the guide plate 68 and the drive ring 66, so that the guide plate 68 can slide smoothly up and down under the action of the curved surface of the drive ring 66.

[0032] Understandably, when the third drive component 61 is activated, its output shaft drives the connecting shaft 62 to rotate, which in turn drives the guide rod 63, limit ring 65, guide disc 68, connecting rod 69, and unloading disc 70 to rotate synchronously. The elastic element 64 will exert a thrust on the guide disc 68, so that the balls 67 on the guide disc 68 can remain in contact with the drive ring 66. During rotation, the balls 67 on the guide disc 68 will roll along the curved surface of the lower surface of the drive ring 66. Due to the undulation of the curved surface, the guide disc 68 will be subjected to periodic forces, which will then roll along the guide rod 63, limit ring 65, guide disc 68, connecting rod 69, and unloading disc 70. 3. The guide plate 68 moves up and down in a reciprocating motion. At the same time, the guide plate 68 drives the feeding plate 70 to move up and down synchronously through the connecting rod 69. Therefore, while the feeding plate 70 rotates with the connecting shaft 62, it also moves up and down in a reciprocating motion. As a result, the dry powder drag-reducing agent can fall evenly through the feeding hole on the feeding plate 70. At the same time, the crushing teeth 71 can crush and disperse the agglomerated dry powder drag-reducing agent, so that the dry powder drag-reducing agent can fall evenly into the working area of ​​the stirring component 4, avoiding the accumulation and agglomeration of dry powder in local areas, thereby improving the preparation quality of the drag-reducing liquid.

[0033] In summary, the dry powder drag-reducing agent preparation device of this utility model ensures a stable and controllable amount of dry powder entering the preparation tank by setting a feeding component and rotating to control the amount of dry powder conveyed. By setting a uniform feeding component, the feeding disc can rotate and reciprocate up and down during the addition of the dry powder drag-reducing agent, which, together with the crushing teeth, crushes and disperses the dry powder, so that the dry powder drag-reducing agent is evenly fed into the preparation tank and fully contacts the fluid with the help of the stirring component. This effectively avoids the accumulation and clumping of dry powder in local areas and improves the preparation quality of the drag-reducing liquid.
