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.

[0018] Please see Figure 1 , Figure 2 and Figure 3This utility model provides a technical solution: an oilfield additive raw material mixing device, including a mixing tank 1, a connecting rod 2 rotatably connected to the middle of the inner bottom wall of the mixing tank 1, an inlet 3 for the additive raw material to enter the inner wall of the mixing tank 1 installed at the right end of the top wall of the mixing tank 1, the top of the connecting rod 2 penetrating the top wall of the mixing tank 1, a mixing component for stirring the additive raw material fixedly connected to the outside of the connecting rod 2, a drive component for controlling the operation of the mixing component installed in the middle of the top wall of the mixing tank 1, and a circulation component for controlling the circulation and stirring of the raw material installed in the left end of the inside of the mixing tank 1; the mixing component includes multiple first blades 4, the multiple first blades 4 are equidistantly and obliquely fixedly connected to the top of the outer wall of the connecting rod 2 with the center of the connecting rod 2 as the axis, second blades 41 are equidistantly fixedly connected to the middle of the outer wall of the connecting rod 2, the second blades 41 are horizontally installed, and third blades 42 are equidistantly fixedly connected to the bottom of the outer wall of the connecting rod 2, the third blades 42 are in contact with the inner bottom wall of the mixing tank 1.

[0019] Through the above technical solution, the device has a first blade 4, a second blade 41 and a third blade 42 fixedly connected from top to bottom on the outer wall of the connecting rod 2. The first blade 4 needs to be designed to be inclined, the second blade 41 is kept in place, and the third blade 42 avoids the raw materials from accumulating on the inner bottom wall of the mixing tank 1. Therefore, it needs to be designed to match the shape of the inner bottom wall of the mixing tank 1 to ensure the uniformity of the raw material mixing.

[0020] Please see Figure 1 , Figure 2 and Figure 3 The drive assembly includes a motor 5, which is mounted on the top wall of the mixing tank 1. The output end of the motor 5 is fixedly connected to a first bevel gear 51, and a second bevel gear 52 is rotatably connected to the middle of the top wall of the mixing tank 1. The first bevel gear 51 and the second bevel gear 52 are meshed together, and a connecting rod 2 is fixedly connected to the inner wall of the second bevel gear 52. The circulation assembly includes a circulation pump 6, which is mounted on the left end of the top wall of the mixing tank 1. The output end of the circulation pump 6 is connected to a circulation pipe 61. One end of the circulation pipe 61 is installed to the bottom left end of the interior of the mixing tank 1, and the other end of the circulation pipe 61 is installed to the top right end of the interior of the mixing tank 1.

[0021] Through the above technical solution, the motor 5 drives the first bevel gear 51 to drive the second bevel gear 52 to rotate. The second bevel gear 52 is fixedly connected to the connecting rod 2, thereby achieving the effect of controlling the rotation of the mixing component through the driving component. At the same time, the rotation speed of the mixing component can be adjusted by controlling the motor 5, which improves the convenience of using the device. One end of the circulation pipe 61 extends to the bottom of the mixing tank 1, and the other end is installed at the top inside the mixing tank 1 to avoid affecting the rotation of the blades. The operation of the circulation pump 6 drives the raw materials to circulate and stir, further ensuring the uniformity of the raw material mixing and meeting the requirements of the device.

[0022] Please see Figure 1 and Figure 3 The bottom wall of the mixing tank 1 is fixedly connected to a feeding block 7. The inner wall of the feeding block 7 is provided with a flow channel 8. The bottom wall of the mixing tank 1 is provided with an opening for the auxiliary raw material to flow out. The flow channel 8 is connected to the opening of the bottom wall of the mixing tank 1. The end of the flow channel 8 forms a discharge port 9. Multiple support feet 11 are fixedly connected at equal intervals to the outer wall of the mixing tank 1. A control panel 10 is installed at the front end of the outer wall of the mixing tank 1. The control panel 10 is electrically connected to the motor 5 and the circulating pump 6 respectively.

[0023] With the above technical solution, the uniformly mixed raw materials flow out through the discharge port 9 at the bottom of the feeding block 7, which is convenient for operators to collect; the mixing tank 1 is installed on the ground by the support feet 11, so as to ensure that it has a certain height and facilitates personnel to work; the device controls the operation of the equipment through the control panel 10 to ensure the stability and accuracy of the device operation.

[0024] Working principle: The mixing tank 1 is supported by multiple support feet 11 on the outside. The auxiliary raw materials are poured into the mixing tank 1 through the feed port 3. The motor 5 is started, and the motor 5 drives the first bevel gear 51 and the second bevel gear 52 to mesh and connect. The second bevel gear 52 drives the connecting rod 2 to rotate synchronously. During the rotation of the connecting rod 2, the first blade 4, the second blade 41, and the third blade 42 rotate synchronously. The first blade 4, the second blade 41, and the third blade 42 are respectively fixedly connected to the upper, middle, and lower parts of the outer wall of the connecting rod 2. Since the first blade 4 is designed with an inclination, it can promote the downward pressure of the raw materials at the top. The second blade 41 is a horizontal straight blade. This enhances radial mixing. The third blade 42 fits against the inner bottom wall of the mixing tank 1 and has a certain curvature, which can prevent the raw materials from settling at the bottom of the mixing tank 1 and ensure that the raw materials are fully mixed. At the same time, the circulation pump 6 is started through the control panel 10. The circulation pump 6 draws the auxiliary raw materials inside the mixing tank 1 into the circulation pipe 61 and then into the mixing tank 1 from the other end of the pipe, realizing the circulation and stirring of the raw materials and further ensuring the uniformity of the raw material mixing. The bottom wall of the mixing tank 1 has an opening that is connected to the flow channel 8 on the inner wall of the feeding block 7. At the same time, it can be connected by a valve to control the discharge time, improving the convenience and practicality of the device.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
