Description

Technical Field

[0001] This utility model relates to the field of weighting agent preparation tank technology, specifically to an organic weighting agent preparation tank device. Background Technology

[0002] A weighting agent preparation tank is a piece of equipment used in oil and gas drilling. It is mainly used to prepare and store weighting agents (such as barite powder) to adjust the density of drilling fluid and ensure drilling safety and efficiency. It mainly consists of a tank, a left agitator, and a right agitator.

[0003] A search revealed that the publication number CN221333896U, entitled "A Composite Water-Reducing Agent Preparation Tank," includes a base, with a tank body fixedly mounted on the upper surface of the base. A cleaning assembly is installed inside the tank body, comprising a rotating shaft located within the tank body, with several rotating rods fixedly mounted on both sides of the shaft. While this composite water-reducing agent preparation tank, through its cleaning assembly, facilitates the cleaning of raw materials from the inner wall, top wall, and bottom wall of the tank body, preventing raw material residue inside the tank, it still has the following drawbacks to some extent:

[0004] The simple mixing structure leads to poor mixing effect. The mixing structure in the above-mentioned preparation tank can only mix the liquid by rotating in a single direction after being driven by a motor. This results in an unsatisfactory mixing effect, uneven mixing, and a long mixing time required to meet the liquid mixing requirements. Furthermore, the above-mentioned preparation tank cannot accurately control the metering of raw materials. Therefore, too much or too little input will affect the quality of drilling fluid preparation. Utility Model Content

[0005] The purpose of this invention is to provide an organic weighting agent preparation tank device that can form convection for stirring, resulting in more thorough and uniform mixing, and can also accurately weigh and measure the raw materials.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An organic weighting agent preparation tank device includes a tank body. Fixing frames are welded to both the left and right sides of the tank body. A drive motor is bolted to the outer side of the fixing frames. The output shaft of the drive motor passes through the inner cavity of the tank body and is fixedly connected to a mounting plate. A left stirring rod and a right stirring rod are welded to the four sides of the inner sides of the left and right mounting plates, respectively. A left feeding screw and a right feeding screw are welded to the middle of the inner sides of the left and right mounting plates, respectively.

[0008] A support frame is welded to the top of the fixed frame, and an mounting frame and a weighing sensor are fixedly connected to the top of the support frame. A weighing tank is bolted to the top of the weighing sensor.

[0009] Preferably, a feeding pipe is welded to the top of the tank, and a silicone sleeve is glued to the inner cavity of the feeding pipe.

[0010] Preferably, the bottom of the weighing tank is welded to a discharge pipe, and the left and right sides of the top of the weighing tank are welded to a filling pipe.

[0011] Preferably, the output shaft of the drive motor is movably connected to the tank body via a sealed bearing, and support bases are welded to both the left and right sides of the bottom of the tank body.

[0012] Preferably, the support base includes a support plate, and threaded rods are threadedly connected to both the front and rear sides of the bottom of the support plate, with a support base plate welded to the bottom of the threaded rods.

[0013] Preferably, a discharge pipe is welded to the bottom of the tank, and an electric valve is fitted onto the surface of the discharge pipe.

[0014] Preferably, both the left and right stirring rods are welded with stirring teeth plates, and feeding pipes are welded through the left and right sides of the top of the mounting frame.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. The weighing sensor weighs the raw materials put into the weighing tank. When the weight reaches the specified weight, the conveying stops and the raw materials flow into the tank. Then, the electric valve on the surface of the discharge pipe is closed and another type of raw material is weighed. This allows for accurate weighing of various raw materials and improves the quality of drilling fluid preparation.

[0017] 2. The forward-rotating left feed screw and the reverse-rotating right feed screw cause the liquid to flow inward and form convection. At the same time, the counter-rotating left and right stirring rods can cut and stir the liquid that forms convection, so as to fully stir the prepared liquid, mix it more thoroughly and evenly, and effectively save preparation efficiency.

[0023] Please see Figures 1-4 An organic weighting agent preparation tank device includes a tank body 1. Fixing frames 12 are welded to both the left and right sides of the tank body 1. A drive motor 3 is bolted to the outside of the fixing frames 12. The output shaft of the drive motor 3 passes through the inner cavity of the tank body 1 and is fixedly connected to a mounting plate 13. A left stirring rod 18 and a right stirring rod 17 are welded to the four sides of the inner sides of the two mounting plates 13, respectively. The right stirring rod 17 is located inside the left stirring rod 18. A left feeding screw 20 and a right feeding screw 22 are welded to the middle of the inner sides of the two mounting plates 13, respectively.

[0024] A support frame 11 is welded to the top of the fixed frame 12. An mounting frame 8 and a weighing sensor 10 are fixedly connected to the top of the support frame 11. A weighing tank 4 is bolted to the top of the weighing sensor 10.

[0025] Please see Figure 2 The top of the tank 1 is welded with a feeding pipe 14. By setting the feeding pipe 14, the discharge pipe 15 can be inserted into the inside for feeding. The inner cavity of the feeding pipe 14 is glued with a silicone sleeve 16. The silicone sleeve 16 is movably connected to the surface of the discharge pipe 15 to prevent the liquid in the tank 1 from splashing out of the feeding pipe 14 during the stirring process.

[0026] Please see Figure 2 and Figure 4 The bottom of the weighing tank 4 is welded with a discharge pipe 15, and the top of the weighing tank 4 is welded with a filling pipe 21 on both the left and right sides. By setting the filling pipe 21, the feeding pipe 9 can be inserted into the tank for feeding. The surface of the feeding pipe 9 is movably connected to the filling pipe 21.

[0027] Please see Figure 1 and Figure 2 The output shaft of the drive motor 3 is movably connected to the tank body 1 through a sealed bearing. Support bases 2 are welded on both the left and right sides of the bottom of the tank body 1. By setting the support bases 2, the support height of the four corners of the tank body 1 can be adjusted to keep it level and avoid shaking.

[0028] Please see Figure 1The support base 2 includes a support plate 5. Threaded rods 6 are threadedly connected to the front and rear sides of the bottom of the support plate 5. A support base plate 7 is welded to the bottom of the threaded rods 6. When the ground is uneven, one of the support base plates 7 will be suspended. At this time, the corresponding threaded rod 6 is reversed so that it extends out of the support plate 5 and pushes the support base plate 7 to contact the ground, ensuring that the device remains balanced.

[0029] Please see Figure 2 and Figure 4 The bottom of the tank 1 is welded with a discharge pipe 19. By setting the discharge pipe 19, the liquid after stirring can be discharged from the tank 1. The surfaces of the discharge pipe 19 and the outlet pipe 15 are fitted with electric valves. By setting the electric valves, the opening and closing of the discharge pipe 19 and the outlet pipe 15 can be controlled by electric control.

[0030] Please see Figure 1 and Figure 2 Both the left stirring rod 18 and the right stirring rod 17 are welded with stirring teeth. By setting the stirring teeth, the area for dividing and stirring the solution can be increased, making the mixing more uniform and thorough. Feeding pipes 9 are welded through the left and right sides of the top of the mounting frame 8.

[0031] In use, this device is connected to an external power supply and controller. The feeding pipes 9 on both sides are connected to an external feeding system. Different raw materials are sequentially fed into the weighing tank 4 through the feeding system. The weighing sensor 10 weighs the raw materials fed into the weighing tank 4, and the weighing information is transmitted to the controller panel for the operator to view. When the weight of the raw materials fed reaches the specified weight, the feeding stops, and then the electric valve on the surface of the discharge pipe 15 is opened, allowing the raw materials in the weighing tank 4 to flow into the tank body 1. Subsequently, the electric valve on the surface of the discharge pipe 15 is closed, and another type of raw material is weighed again. This allows for accurate weighing of various raw materials, improving drilling efficiency. Regarding the preparation quality of the liquid, after various raw materials flow into tank 1, the drive motor 3 on the left side rotates forward and the drive motor 3 on the right side rotates in reverse. The left stirring rod 18 and the left feeding screw 20 on the left side rotate clockwise inside tank 1, while the right stirring rod 17 and the right feeding screw 22 on the right side rotate counterclockwise. In this way, the forward-rotating left feeding screw 20 and the reverse-rotating right feeding screw 22 can make the liquid flow inward to form convection. At the same time, the left stirring rod 18 and the right stirring rod 17 rotating in the opposite direction can divide and stir the liquid that forms convection, so as to fully stir the prepared liquid, mix it more thoroughly and evenly, and effectively save preparation efficiency.

[0032] In summary, this organic weighting agent preparation tank device, through the coordinated use of tank body 1, drive motor 3, weighing tank 4, weighing sensor 10, feeding pipe 14, right stirring rod 17, left stirring rod 18, left feeding screw 20 and right feeding screw 22, solves the problems of poor mixing effect due to relatively simple stirring method, insufficient uniform and thorough stirring, and inability to accurately control the metering of raw materials, which affects the quality of drilling fluid preparation.
