Description

Technical Field

[0001] The utility model relates to the technical field of drilling fluid preparation, in particular to a multi-specification adaptable flip-type experimental drilling fluid slurry preparation machine. Background Art

[0002] Drilling fluid is a general term for various circulating fluids that meet the needs of drilling work with their multiple functions during the drilling process. The preparation of drilling fluid is divided into industrial preparation and experimental preparation. Industrial preparation is mainly used for on-site application of drilling fluid, and experimental preparation is mainly used for research and development of drilling fluid.

[0003] The drilling fluid slurry preparation machine used in our company's experiments is a flip-type slurry preparation machine, but the slurry preparation amount of this slurry preparation machine is limited during use, and the slurry preparation amount is relatively small, which cannot meet the needs of daily experiments. If the slurry preparation barrel is directly replaced with a large-capacity slurry preparation barrel, due to the characteristics of the flip-type slurry preparation machine, the reason why it can be flipped is that the length of the stirring shaft, the diameter and depth of the slurry preparation barrel need to match each other to achieve normal flipping. Otherwise, for example, if the depth of the slurry preparation barrel is increased, then during stirring, it is naturally necessary to extend the stirring shaft to stir to the bottom. However, when flipping at this time, the stirring shaft will be blocked by the inner wall of the slurry preparation barrel and cannot be flipped out.

[0004] In addition, when the slurry mixing machine is mixing, the rapid mixing will cause splashing of the slurry and vibration of the slurry mixing barrel. The current slurry mixing machine only places the slurry mixing barrel on a base without any stabilizing device.

[0005] On this basis, the utility model provides a multi-specification adaptable flip-type experimental drilling fluid slurry mixing machine to solve the problem. Utility Model Content

[0006] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a multi-specification adaptable flip-type experimental drilling fluid slurry preparation machine. The utility model has a novel structure and ingenious conception, and effectively solves the technical problems that the existing experimental slurry preparation machines cannot meet the requirements of multi-specification slurry preparation quantities and are unstable.

[0007] A multi-specification adaptable flip-type experimental drilling fluid slurry preparation machine, comprising a base, a built-in controller in the base, the controller connected to a display screen placed on the base, a flip-type stirring motor is arranged on the base, the stirring motor is connected to the controller, the controller is connected to a speed regulating switch on the base, a slurry preparation barrel placed below the stirring motor is placed on the base, and the invention is characterized in that a connecting seat is fixed to the lower end of the stirring motor, an electric telescopic rod is fixed to the lower end of the connecting seat, a bearing sleeve is fixed to the lower end of the electric telescopic rod, a stirring shaft is fixed to the lower end of the bearing sleeve, a dividing cylinder with an opening at the lower end and a cavity inside is sleeved on the stirring shaft, a plurality of dividing holes are opened on the side wall of the dividing cylinder, and a turbine fixed to the lower end of the stirring shaft is arranged in the dividing cylinder.

[0008] Preferably, the base is provided with two symmetrical support columns, a bearing seat is fixed on the support column, the bearing seat is rotatably connected to a motor plate via a side plate, a stirring motor is fixed on the motor plate, a motor housing is fixed outside the stirring motor, and a heat dissipation hole is opened in the motor housing.

[0009] Preferably, the base is fixed with symmetrically arranged telescopic cylinders, a support column is slidably arranged inside the telescopic cylinders, an electric telescopic cylinder is fixed between the two telescopic cylinders, and the upper end of the electric telescopic cylinder is connected to the bearing seat.

[0010] Preferably, a stabilizing ring is fixed on the base, and a fixing disc matching the stabilizing ring is fixed on the lower end of the slurry mixing barrel.

[0011] Preferably, a barrel cover is buckled on the slurry mixing barrel, and a rectangular hole is opened on the barrel cover.

[0012] Preferably, T-shaped slide grooves are provided on both sides of the base, and a clamping device is slidably installed in the T-shaped slide grooves.

[0015] The utility model has the following technical effects.

[0016] The utility model realizes the extension and retraction of the stirring shaft through the electric telescopic rod, so that slurry mixing barrels of different specifications can achieve stirring, mixing and normal flipping. When the capacity of the slurry mixing barrel becomes larger and the preparation and stirring are finished, the electric telescopic rod retracts the stirring shaft to realize normal flipping of the stirring shaft. When the depth of the stirring barrel is increased to increase the capacity, in order to prevent the height of the slurry mixing barrel from being higher than the motor plate and unable to achieve normal stirring, the motor plate can be adapted to be raised through the electric telescopic cylinder to ensure normal stirring of the stirring shaft.

[0017] The barrel cover is also used to prevent the slurry from splashing during stirring, and the cooperation of the T-shaped slider and the T-shaped slide groove allows the clamping rod to press the barrel cover downward to ensure the stability of the slurry mixing barrel during stirring.

DETAILED DESCRIPTION

The contents mentioned in the following embodiments are all based on the drawings in the specification.

[0025] Various exemplary embodiments of the present utility model will be described below with reference to the accompanying drawings.

[0026] The utility model is a multi-specification adaptive flip-type experimental drilling fluid slurry preparation machine, which is mainly used for experimental research and development preparation, including a base 1, the base 1 is a prior art, a controller is arranged inside, an external power cord, and a rated power supply of 220V / 50Hz, a stable shock-absorbing bottom pad is fixed at the lower end of the base 1, the controller is connected to a display screen 2 placed on the base 1, a flippable stirring motor 3 is arranged above the base 1, the stirring power is 0.6KW, the stirring speed is 0-3000r / min, the stirring motor 3 is a stepless speed regulation motor, the stirring motor 3 is connected to the controller, the controller is connected to a stepless speed regulation switch 4 placed on the base 1, a slurry preparation barrel 5 placed below the stirring motor 3 is placed on the base 1, a stirring shaft 9 is fixed at the lower end of the stirring motor 3, and the specific connection method is to fix the stirring motor 3 at the lower end of the stirring motor 3 A connecting seat 6 is provided, and the connecting seat 6 is used to provide support for the electric telescopic rod 7 below. The electric telescopic rod 7 is fixed at the lower end of the connecting seat 6, and the electric telescopic rod 7 is connected to the controller. The controller is connected to the inching button switch placed on the base 1 for controlling the electric telescopic rod 7. A bearing sleeve 8 is fixed to the lower end of the electric telescopic rod 7. The bearing sleeve 8 is used to connect the electric telescopic rod 7 and the stirring shaft 9 below. The stirring shaft 9 is fixed below the bearing sleeve 8, and a dividing cylinder 10 is fixed to the lower end of the stirring shaft 9. The interior of the dividing cylinder 10 is a cavity with an opening at the lower end. A plurality of dividing holes 11 uniformly distributed in a circle are opened on the side wall of the dividing cylinder 10. A turbine shaft fixed to the stirring shaft 9 is provided in the dividing cylinder 10, and a turbine 12 is provided on the turbine shaft. The rotation direction of the turbine 12 makes the slurry below the turbine 12 flow to the turbine 12.

[0027] When a larger amount of slurry is needed, replace the slurry mixing barrel 5 of appropriate size, control the stirring motor 3 to stir normally, and after the slurry mixing is completed, control the electric telescopic rod 7 to retract upward, and move the stirring shaft 9 upward. When the stirring shaft 9 moves upward or the stirring shaft 9 moves to at least the top, flip the stirring motor 3, the stirring shaft 9 can be flipped out without any impact, and then the slurry mixing barrel 5 is taken away.

[0028] When slurry mixing is performed, the slurry mixing barrel 5 is placed first, the stirring motor 3 is reversed and placed above the slurry mixing barrel 5, the electric telescopic rod 7 is controlled to extend downward, the stirring shaft 9 is placed in the slurry mixing barrel 5, and the slurry mixing is started.

[0029] The stirring shaft 9 is extended and retracted by means of an electrically extendable and controllable electric telescopic rod 7, so that the stirring shaft 9 can be extended when working and retracted when not working, so that the stirring shaft 9 can be turned over with the stirrer 3.

[0030] The stirring shaft 9 drives the turbine 12, so that the mud under the slurry mixing barrel 5 flows toward the turbine 12. After reaching the dividing cylinder 10, it is first stirred by the turbine 12, and then broken up and thrown out by the dividing cylinder 10. Many tests have proved that the stirring rate is relatively fast, and the mud can be quickly guided to the dividing cylinder 10, and then quickly stirred and divided. The overall stirring speed is fast and the stirring efficiency is high.

[0031] Furthermore, the flip-type stirring motor 3 is specifically implemented as follows: two symmetrical support columns 13 are provided on the base 1, a bearing seat 14 is fixed above the two support columns 13, a motor plate 16 is rotatably connected to the bearing seat 14 via a rotating shaft and a side plate 15, a stirring motor 3 placed above the slurry mixing barrel 5 is fixed at the end of the motor plate 16, a motor housing 17 is fixed to the outside of the stirring motor 3, a motor housing cover is buckled above the motor housing 17, and a heat dissipation hole 18 is opened on the side wall of the motor housing 17.

[0032] The motor plate 16 is turned by hand to realize the overturning of the stirring motor 3. Specifically, the locking is to be provided with a limit plate after the motor plate 16 is laid flat, so that the motor plate 16 cannot be further turned downward.

[0033] Alternatively, a tightening bolt may be provided at the rotating position of the shaft, and when the motor plate 16 is turned over to a suitable position, the shaft is tightened with the tightening bolt, or other conventional technical means may be used.

[0034] Furthermore, when replacing a large-capacity slurry mixing barrel 5, some of the large-capacity slurry mixing barrels 5 have increased inner diameters, while others have increased heights. When the height is increased, it may be affected by the position height of the motor plate 16, so symmetrically arranged telescopic cylinders 19 are fixed on the two bases 1, and support columns 13 are slidably arranged inside the telescopic cylinders 19. The support columns 13 can move up and down synchronously in the two telescopic cylinders 19, and an electric telescopic cylinder 20 is fixed between the two telescopic cylinders 19. The upper end of the electric telescopic cylinder 20 is connected to the bearing seat 14, and the electric telescopic cylinder 20 is connected to the controller, and the controller is connected to the momentary push button switch placed on the base 1, which is used to control the height of the entire motor plate 16.

[0035] Furthermore, in order to ensure the stability of the slurry during stirring, a circular stabilizing ring 21 is fixed on the base 1, and a fixed disc 22 is fixed at the bottom of the slurry mixing barrel 5. The fixed disc 22 can be placed in the stabilizing ring 21 to improve the stability of the slurry mixing barrel 5 during reaction.

[0036] Furthermore, in order to prevent the slurry from splashing during preparation, a barrel cover 23 is provided on the slurry preparation barrel 5, and a rectangular hole 24 is provided on the barrel cover 23. When preparing, the slurry preparation barrel 5 is placed first, and then the motor plate 16 is turned over. At this time, the motor plate 16 is placed above the slurry preparation barrel 5, and the barrel cover 23 cannot be directly buckled from the top down, and the stirring shaft 9 is placed in the slurry preparation barrel 5. Therefore, when the barrel cover 23 is buckled, a rectangular hole 35 needs to be provided on the barrel cover 34 to attach the barrel cover 34 when buckling. Figure 1-2 Taking the direction as an example, the cylinder cover 23 is moved from the left side of the slurry mixing barrel 5 to the right, and the stirring shaft 9 passes through the rectangular hole 24. When the cylinder cover 23 is placed just above the slurry mixing barrel 5, it can be buckled down on the slurry mixing barrel 5.

[0037] Furthermore, symmetrically arranged T-shaped slide grooves 25 are opened on both sides of the slurry mixing barrel 5 , and a clamping device is slidably installed in the T-shaped slide grooves 25 , and the clamping device is used to clamp the slurry mixing barrel 5 .

[0038] Furthermore, the clamping device includes a T-shaped slider 26 sliding in the T-shaped slide groove 25, a vertical clamping cylinder 27 is fixed on the T-shaped slider 26, an internal thread is provided in the clamping cylinder 27, the clamping cylinder 27 is threadedly connected to a clamping rod 28, and the clamping rod 28 can be moved up and down in the clamping cylinder 27 by rotating, and a clamping plate 29 is fixed to the upper end of the clamping rod 28.

[0039] First, slide the T-shaped slider 26 to the side of the slurry mixing barrel 5, and then rotate the clamping rod 28 downward so that the clamping plate 29 firmly presses the barrel cover 23, applying a downward clamping force to the barrel cover 23 to ensure the stability of the slurry mixing barrel 5 during stirring.

[0040] Furthermore, in order to ensure that the T-shaped slider 26 is limited and fixed after moving to the appropriate position, a limit hole is opened on the T-shaped slider 26, and a limit bolt 30 is installed in the limit hole. When the T-shaped slider 26 moves to the appropriate position beside the slurry mixing barrel 5, the limit bolt 30 is rotated downward to press against the T-shaped slide groove 25 to lock it to prevent the T-shaped slider 26 from moving.

[0041] Working principle:

[0042] After selecting a slurry mixing barrel 5 of appropriate capacity and placing the slurry mixing barrel 5, control the electric telescopic barrel 20 to adjust the height of the motor plate 16, flip the motor plate 16, place the stirring motor 3 directly above the slurry mixing barrel 5, control the electric telescopic rod 7 to move downward to an appropriate distance, and then buckle the barrel cover 23 on the slurry mixing barrel, move the T-shaped slider 26 to the side of the slurry mixing barrel 5, rotate the limit bolt 30 to fix it, rotate the clamping rod 28 to clamp and fix the barrel cover 23, turn on the stirring motor 3 to prepare the slurry, and the turbine 12 makes the slurry flow rapidly toward the dividing barrel 10, and then it is rapidly divided and flows out from the dividing hole 11 under the stirring of the turbine 12 for stirring.

[0043] The utility model realizes the extension and retraction of the stirring shaft through the electric telescopic rod, so that slurry mixing barrels of different specifications can achieve stirring, mixing and normal flipping. When the capacity of the slurry mixing barrel becomes larger and the preparation and stirring are finished, the electric telescopic rod retracts the stirring shaft to realize normal flipping of the stirring shaft. When the depth of the stirring barrel is increased to increase the capacity, in order to prevent the height of the slurry mixing barrel from being higher than the motor plate and unable to achieve normal stirring, the motor plate can be adapted to be raised through the electric telescopic cylinder to ensure normal stirring of the stirring shaft.

[0044] The barrel cover is also used to prevent the slurry from splashing during stirring, and the cooperation of the T-shaped slider and the T-shaped slide groove allows the clamping rod to press the barrel cover downward to ensure the stability of the slurry mixing barrel during stirring.

[0045] Although the content of the utility model has been described in detail through the above preferred embodiments, it should be recognized that the above description should not be considered as a limitation of the utility model. After reading the above content, various modifications and substitutions of the utility model will be obvious to those skilled in the art. Therefore, the protection scope of the utility model should be limited by the attached claims.
