Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0031] See also Figure 1-5 A blending kettle for mechanical oil production comprises a kettle body 1, a blanking base 3 is installed at the lower end of the kettle body 1, a liquid drop hole 31 is opened at the bottom end of the blanking base 3, a liquid outlet valve 4 is installed inside the liquid drop hole 31, a plurality of evenly distributed support angles 2 are fixedly connected to the lower end of the blanking base 3, a plurality of connecting seats 5 are fixedly connected between the bottom inner walls of the kettle body 1, a positioning platform 6 is installed at the center end of the plurality of connecting seats 5, a mixing component 7 for stirring is installed at the upper end of the positioning platform 6, a connecting rod 8 is movably connected to the upper end of the mixing component 7, and the connecting rod 8 passes through the top of the kettle body 1.

[0032] During the use of this scheme, in order to make the existing machine oil more evenly stirred and heated during the production process and to speed up the production efficiency, in this embodiment, the personnel fill the machine oil from the liquid inlet on the side of the kettle body 1, and then the personnel pull the connecting rod 8 up and down, so that the mixing component 7 forms self-rotation when moving up and down inside the kettle body 1, and realizes forward and reverse stirring operation when rotating up and down, thereby greatly optimizing the velocity field when the machine oil is stirred and reducing the influence of the machine oil caused by the steering, optimizing the uniformity of the machine oil mixing, making the machine oil flow smoothly when mixing and tending to the laminar state, and also reducing the forced convection heat exchange effect between the media, so that the temperature inside the kettle body 1 is also improved uniformly, and the rapid and uniform mixing of the machine oil is realized;

[0033] The stirring rod used in the utility model is a spiral arc stirring rod. Compared with the horizontal axis stirring rod used in the prior art, the stirring flow rate and circulation flow rate are significantly increased, which greatly enhances the mixing efficiency of the mechanical oil and also helps to improve the temperature uniformity inside the thermostatic tank.

[0034] At the same time, in this embodiment, the up and down pushing action of the connecting rod 8 can also be connected with a hydraulic rod and an electric telescopic rod, so as to realize electric stirring work and reduce labor.

[0035] See also Figure 1-4 The mixing assembly 7 includes a ball screw 71 fixedly connected to the upper end of the positioning platform 6, a transmission sleeve 72 is sleeved on the outer end of the ball screw 71, a bearing seat 73 is installed on the upper end of the transmission sleeve 72, and the top end of the bearing seat 73 is movably connected to the connecting rod 8.

[0036] More specifically, a plurality of spirally arranged stirring rods 74 are fixedly connected to the outer end of the transmission sleeve 72 , a stirring disk 75 is provided on the outer side of the bearing seat 73 , and a plurality of brackets 76 are fixedly connected between the stirring disk 75 and the bearing seat 73 .

[0037] In the process of using the present invention, when the connecting rod 8 moves up and down, the transmission sleeve 72 moves synchronously with it and cooperates with the ball screw 71. At the same time, under the action of the rotation transmission of the bearing seat 73, it is converted into a rotational motion, so that when the connecting rod 8 moves up and down, the transmission sleeve 72 drives the stirring rod 74 and the stirring plate 75 to stir and mix the machine oil.

[0038] When the transmission sleeve 72 moves down to the bottom, the personnel pulls the connecting rod 8 upward again, causing the transmission sleeve 72 to rotate and stir in the opposite direction to the original direction when moving upward, so that the machine oil can be mixed and stirred more fully;

[0039] Furthermore, when the mechanical oil is mixed and stirred inside the kettle body 1, the surfaces of the ball screw 71 and the transmission sleeve 72 can also be lubricated to improve the wear resistance and transmission performance between the two and improve the efficiency of the mechanical oil stirring.

[0040] See also Figure 1-2 and Figure 5 A built-in cavity 11 is opened inside the kettle body 1, and the connecting rod 8 penetrates between the inner walls of the built-in cavity 11. A spring 12 is installed between the upper and lower inner walls of the built-in cavity 11. The spring 12 is sleeved on the outside of the connecting rod 8, and the top of the connecting rod 8 is fixedly connected to a limited handle 81.

[0041] During use of the present solution, after the connecting rod 8 moves upward, it can have an automatic rebound movement due to the setting of the spring 12. When a subsequent person manually pulls the connecting rod 8, the efficiency of the forward and reverse stirring of the stirring rod 74 is improved due to its rebound effect.

[0042] See also Figure 1-2 The kettle body 1 is composed of two glass plates separated by 0.1-0.2 mm, the gap between the two glass plates is vacuum sealed, and the outer glass plate is low-radiation glass.

[0043] During use, the central interlayer of the kettle body 1 is vacuum-sealed, which minimizes the heat energy lost by convection and radiation when the internal mechanical oil is mixed and stirred, achieving a thermal insulation effect similar to that of a glass thermos bottle, avoiding rapid heat loss inside the kettle body 1 and enhancing the efficiency of mechanical oil mixing.

[0044] See also Figure 2-3 The connection seat 5 is in the shape of a triangular column, and the positioning platform 6 is in the shape of a truncated cone.

[0045] During use, the present invention makes the connecting seat 5 into a triangular column shape and the positioning platform 6 into a truncated cone shape, so that the stirred and mixed machine oil is not easily retained and adhered to the top surfaces of the two, thereby avoiding machine oil residue after the mixing work is completed.

[0046] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
