A mixing device for oil drilling additives

Abstract

This utility model discloses a mixing device for oil drilling additives, relating to the field of oil drilling technology. The utility model includes a mixing tank with a U-shaped support frame mounted on its top, and further includes: a vibrating unit installed outside the mixing tank to reduce the adhesion of raw materials to the tank walls; and a mixing section installed on top of the mixing tank. Specifically, during the mixing process, a motor drives a rotating shaft and a cam to rotate. The cam periodically pushes a moving plate to compress a spring and move a vibrating hammer away from the mixing tank. When the cam is no longer in contact with the moving plate, the spring returns to its original position, causing the vibrating hammer to strike the outer wall of the mixing tank.

Description

Technical Field

[0001] This utility model belongs to the field of petroleum drilling technology, and in particular relates to a mixing device for petroleum drilling additives. Background Technology

[0002] Oil drilling is a complex and critical engineering operation aimed at extracting oil resources from deep underground. In this process, oil drilling additives play an indispensable role, effectively improving drilling fluid performance, such as enhancing its stability, reducing friction, and preventing wellbore collapse, thereby improving drilling efficiency and safety, which is of great significance to the smooth progress of the entire oil extraction operation.

[0003] To prepare high-performance oil drilling additives, a mixing device is needed to mix various raw materials in a specific ratio. However, because the raw materials for oil drilling additives often have a certain degree of viscosity, and the internal structure of the mixing device may be poorly designed, the additives are prone to adhering to the inner wall of the device during mixing, resulting in wall adhesion. Currently, some mixing devices are unable to solve the problem of wall adhesion during the raw material mixing process. In the long run, this not only wastes raw materials and increases production costs, but may also affect the uniformity of subsequent mixing due to the accumulation of wall-adhered substances, leading to a decline in product quality. In severe cases, it may even hinder the normal operation of the device and cause production accidents. Utility Model Content

[0004] The purpose of this invention is to provide a mixing device for oil drilling additives. It incorporates a vibrating section. Specifically, during the mixing process, a motor drives a rotating shaft and a cam to rotate. The cam periodically pushes a moving plate to compress a spring and moves a vibrating hammer away from the mixing drum. When the cam is no longer in contact with the moving plate, the spring resets, causing the vibrating hammer to strike the outer wall of the mixing drum. The resulting vibration is transmitted into the drum, effectively breaking up the phenomenon of raw materials adhering to the wall. This improves the fluidity of the raw materials during mixing, reduces dead zones and residues caused by adhering to the wall, and solves the problem of adhering to the wall that is difficult to address in some mixing devices.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a mixing device for oil drilling additives, comprising a mixing tank, a U-shaped support frame mounted on the top of the mixing tank, and further comprising:

[0007] A vibrating element, installed on the outside of the mixing tank, is used to reduce the adhesion of raw materials to the walls of the mixing tank; and

[0008] A mixing section is installed on top of a mixing tank and is used to mix and stir the raw materials inside the mixing tank.

[0009] The mixing tank is equipped with two sets of vibration sections, which are mirror images of each other on the outer wall of the mixing tank. The working principle and components of the two sets of vibration sections are exactly the same.

[0010] Furthermore, the vibrating part includes a vibration assembly mounted on the outside of the mixing tank, the vibration assembly being used to hammer the mixing tank, causing the mixing tank to vibrate; and

[0011] A drive assembly, mounted outside the mixing tank, is used to provide power to the vibration assembly;

[0012] The vibration component causes the mixing tank to vibrate by striking the outer wall of the mixing tank, thereby transmitting the vibration to the inside of the mixing tank.

[0013] Further, the mixing unit includes a loading and unloading assembly, which is installed outside the mixing tank and is used to load and unload materials into the mixing tank; and

[0014] A stirring assembly is installed on top of a mixing tank and is used to mix the raw materials inside the mixing tank.

[0015] A strengthening component is installed on top of the mixing tank and is used to enhance the mixing effect of the stirring component;

[0016] The mixing effect of the raw materials in the mixing tank is improved by the cooperation of the stirring component and the strengthening component, so that the raw materials in the mixing tank are mixed more evenly.

[0017] Furthermore, the vibration assembly includes a housing installed on the outer wall of the mixing tank, with two fixed rods fixedly connected to the inner wall of the housing, a movable plate slidably connected to the outer wall of the two fixed rods, and springs wound around the outer wall of each of the two fixed rods. Two vibrating hammers are fixedly connected to the right side of the movable plate.

[0018] The container is connected to the mixing tank by bolts.

[0019] Furthermore, the drive assembly includes a motor mounted on the top of the housing, the output shaft of the motor being fixedly connected to a rotating shaft via a coupling, the bottom end of the rotating shaft extending into the interior of the housing and rotatably connected to the housing, and a cam being fixedly connected to the bottom end of the rotating shaft.

[0020] The cam periodically contacts the moving plate as the rotating shaft rotates.

[0021] Furthermore, the loading and unloading assembly includes a loading port fixedly connected to the top of the mixing tank, a discharge port fixedly connected to the bottom of the mixing tank, and a valve fixedly connected to the outer wall of the discharge port;

[0022] The feed inlet and discharge outlet are fixedly connected to the mixing tank by welding.

[0023] Furthermore, the stirring assembly includes a second motor mounted on the top of a U-shaped support frame. The output shaft of the second motor is fixedly connected to a second rotating shaft. The bottom end of the second rotating shaft passes through the U-shaped support frame and is rotatably connected to the U-shaped support frame. A first sleeve is slidably connected to the outer wall of the second rotating shaft. A stirring shaft is fixedly connected to the bottom end of the first sleeve. The bottom end of the stirring shaft extends into the interior of the mixing tank and is slidably connected to the mixing tank. Two spiral blades are fixedly connected to the outer wall of the stirring shaft.

[0024] The second rotating shaft is slidably connected to the first sleeve by a snap-fit ​​mechanism, so that the first sleeve can rotate along with the second rotating shaft as the second rotating shaft rotates.

[0025] Furthermore, the reinforcing component includes a second sleeve installed on the inner top wall of the U-shaped support frame. The second sleeve is fitted onto the outer wall of the first sleeve and is slidably connected to the first sleeve. The outer wall of the first sleeve has an annular groove. The inner wall of the second sleeve is fixedly connected to a guide rod. One end of the guide rod away from the inner wall of the second sleeve extends into the interior of the annular groove and is slidably connected to the annular groove.

[0026] Among them, sleeve two is connected to the U-shaped support frame by bolt connection.

[0027] This utility model has the following beneficial effects:

[0028] 1. By setting up a vibrating section, specifically during the mixing process of raw materials, the motor drives the rotating shaft and cam to rotate. The cam periodically pushes the moving plate to compress the spring and drives the vibrating hammer away from the mixing drum. When the cam is no longer in contact with the moving plate, the spring returns to its original position and drives the vibrating hammer to strike the outer wall of the mixing drum. The resulting vibration is transmitted to the inside of the drum, which can effectively break the phenomenon of raw materials sticking to the wall, thereby improving the fluidity of the raw materials during the mixing process and reducing the mixing dead corners and residues caused by sticking to the wall.

[0029] 2. By setting up a mixing section, specifically when mixing raw materials, motor two drives shaft two and sleeve one to rotate, so that the stirring shaft drives the spiral blades to stir the raw materials. At the same time, the guide rod on the inner wall of sleeve two slides in the annular groove of sleeve one, causing the stirring shaft to move up and down reciprocally. This upgrades simple rotary stirring to a compound stirring mode of rotary and axial motion, which enhances the convection and diffusion of raw materials at different levels, effectively improves the mixing uniformity, and shortens the mixing time.

[0030] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0060] The inner wall dimensions of the annular groove 332 are adapted to the outer wall dimensions of the guide rod 333.

[0061] A specific application of this embodiment is as follows: When using this device, the raw materials to be mixed are first fed into the mixing tank 1 through the feeding port 311. At this time, the valve 313 installed on the outer wall of the discharge port 312 is in a closed state. Therefore, the raw materials to be mixed will be temporarily stored inside the mixing tank 1. Then, the raw materials are mixed by the mixing section 3. During the mixing process, the motor 221 on the top of the housing 211 is started simultaneously. The motor 221 drives the rotating shaft 222 to rotate. When the rotating shaft 222 rotates, it drives the cam 223 to rotate. During the rotation, the cam 223 will interact with the moving plate 2. 13. Periodic contact: When the cam 223 contacts the moving plate 213, it pushes the moving plate 213, causing the moving plate 213 to move along the fixed rod 212. During the movement of the moving plate 213, the spring 214 is compressed, and the vibrating hammer 215 moves away from the outer wall of the mixing tank 1. When the cam 223 no longer contacts the moving plate 213, the spring 214 is reset and stretched under its own elasticity, thereby driving the moving plate 213 to reset, and then driving the vibrating hammer 215 to reset, so that the vibrating hammer 215 hammers the outer wall of the mixing tank 1, generating vibration and transmitting it into the tank, reducing the phenomenon of raw materials sticking to the wall.

[0062] When the raw materials in the mixing tank 1 are mixed and stirred by the mixing section 3, the motor 321 at the top of the U-shaped support frame 11 is started first, so that the motor 321 drives the rotating shaft 322 to rotate. When the rotating shaft 322 rotates, it drives the sleeve 323 to rotate. When the sleeve 323 rotates, it drives the spiral blade 325 to rotate through the stirring shaft 324. The spiral blade 325 mixes the raw materials in the mixing tank 1. During the rotation of the sleeve 323, the guide rod 333 on the inner wall of the sleeve 331 slides in the annular groove 332 of the sleeve 323, causing the sleeve 323 to slide up and down on the outer wall of the rotating shaft 322 and the inner wall of the sleeve 331, thereby driving the stirring shaft 324 to produce up and down reciprocating motion, enhancing the mixing effect.
