Description

Technical Field

[0001] This utility model relates to the technical field of slurry mixing devices, specifically an oil drilling and production slurry mixing device. Background Technology

[0002] Oil extraction refers to the act of digging and extracting oil from places where oil reserves exist. During the oil drilling process, drilling mud is prepared to cool the drill bit while it carries rock cuttings to the surface, where it is then mixed by a mud mixing device.

[0003] Currently, in the use of existing oil drilling mud mixing devices, solid particles (such as bentonite, barite, drill cuttings, etc.) precipitate or deposit at the lower end of the device, failing to mix fully with the mud. This situation leads to unstable mud properties (such as uneven density and viscosity fluctuations), and may even affect drilling safety and efficiency. To address this, we propose an oil drilling mud mixing device. Utility Model Content

[0004] The purpose of this utility model is to provide an oil drilling mud mixing device that has the advantage of thorough mud mixing. It solves the problem that in the use of existing oil drilling mud mixing devices, solid particles precipitate or deposit at the lower end of the device and cannot be fully mixed with the mud. This situation leads to unstable mud performance and may even affect drilling safety and efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an oil drilling and production slurry mixing device, comprising:

[0006] A mixing tank, wherein a fixing frame is fixedly installed at the middle of the top of the mixing tank;

[0007] A drive motor is fixedly installed on the top of the fixed frame. The output end of the drive motor is connected to a hollow rotating shaft through a coupling. The upper end of the hollow rotating shaft is connected to a discharge pipe groove. From top to bottom, a downward push impeller, a mixing rod, an upward push impeller, and a drum mixing tank are fixedly installed on the outer surface of the hollow rotating shaft. A drain pipe is connected between one end of the drum mixing tank and the lower end of the hollow rotating shaft.

[0008] Preferably, feed hoppers are provided at both the left and right ends of the top of the mixing tank.

[0009] Preferably, a discharge pipe is provided at the bottom of the mixing tank, and a valve body is provided at the upper end of the discharge pipe.

[0010] Preferably, the upper end of the hollow rotating shaft is movably connected to the middle end of the top of the mixing tank via a bearing.

[0011] Preferably, a support sleeve is fixedly connected to the lower end of the outer surface of the mixing tank, and support legs are fixedly connected to the four sides of the bottom of the support sleeve and the four sides of the bottom of the mixing tank.

[0012] Preferably, the agitator is a fan-shaped structure with a guide channel on one side.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention can automatically transport the slurry from the lower end of the mixing tank to the upper end of the mixing tank during the mixing process. In conjunction with the impeller that pushes the slurry up and down, the mixing rod achieves the best mixing state. It is easy to use and has a good mixing effect. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] The mixing tank 1, feed hopper 101, fixing frame 102, discharge pipe 103, support sleeve 2, support leg 201, drive motor 3, discharge pipe trough 301, hollow rotating shaft 302, diversion pipe 303, drum-in mixing tank 304, downward push impeller 305, mixing rod 306 and upward push impeller 307 of this application are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known by those skilled in the art through technical manuals or conventional experimental methods.

[0022] Example 1

[0023] Please see Figures 1-4 As shown, this utility model provides a technical solution: an oil drilling and production slurry mixing device, comprising:

[0024] Mixing tank 1, with a fixing frame 102 fixedly installed at the middle of the top of the mixing tank 1;

[0025] The drive motor 3 is fixedly installed on the top of the fixed frame 102. The output end of the drive motor 3 is connected to the hollow rotating shaft 302 through a coupling. The upper end of the hollow rotating shaft 302 is connected to the discharge pipe groove 301. The outer surface of the hollow rotating shaft 302 is fixedly installed from top to bottom with the downward push impeller 305, the mixing rod 306, the upward push impeller 307 and the drum mixing tank 304. One end of the drum mixing tank 304 is connected to the lower end of the hollow rotating shaft 302 through the drainage pipe 303.

[0026] The mixing tank 1 has a feed hopper 101 at both the left and right ends of the top, a discharge pipe 103 at the bottom, and a valve body at the upper end of the discharge pipe 103. The upper end of the hollow rotating shaft 302 is movably connected to the middle end of the top of the mixing tank 1 through a bearing. The mixing tank 304 is a fan-shaped structure with a guide groove on one side.

[0027] This technical solution: During use, it is necessary to check whether the equipment is functioning normally. If everything is normal, the mains power is supplied to the device via the main control switch. When the slurry to be mixed is fed into the mixing tank 1 through the feed hopper 101, the external controller (which belongs to the prior art) turns on the drive motor 3. When the drive motor 3 is working, it drives the hollow rotating shaft 302 to rotate. When the hollow rotating shaft 302 rotates, it drives the discharge pipe trough 301, the downward push impeller 305, the mixing rod 306, the upward push impeller 307, and the drum mixing tank 304 to rotate. When the upward push impeller 307 rotates, it can push the mixed slurry in the mixing tank 1 upward from the lower end of the inner cavity of the mixing tank 1. At the same time, the rotation of the drum mixing tank 304 will pressurize the slurry at the lower end of the inner cavity of the mixing tank 1 and enter the guide groove of the drum mixing tank 304. The pressure generated by the rotation will cause the slurry at the lower end of the inner cavity of the mixing tank 1 to enter the interior of the hollow rotating shaft 302 through the inclined drainage pipe 303 (e.g., Figure 2 and Figure 4(As shown), the slurry flowing through the hollow rotating shaft 302 will then be discharged outward from the discharge pipe 301 to the upper end of the inner cavity of the mixing tank 1. When the downward push impeller 305 rotates, it can push the mixed slurry at the upper end of the inner cavity of the mixing tank 1 downward, and cooperate with the rotating mixing rod 306 to achieve the ability to fully mix the slurry.

[0028] It should be noted that the drive motor 3, hollow rotating shaft 302, diversion pipe 303, drum mixing tank 304, downward push impeller 305, mixing rod 306 and upward push impeller 307 used in this device can all be purchased directly from the market. At the same time, the connection method and electrical connection relationship of each component adopt mature conventional methods in the existing technology, so they will not be described in detail here.

[0029] Example 2

[0030] Based on Embodiment 1, this utility model is as follows: Figures 1-4 As shown, a support sleeve 2 is fixedly connected to the lower end of the outer surface of the mixing tank 1, and support legs 201 are fixedly connected to the bottom of the support sleeve 2 and the bottom of the mixing tank 1.

[0031] This technical solution ensures the stability of the device during use by setting up the support sleeve 2 and the support leg 201.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
