Description

Technical Field

[0001] The utility model mainly relates to the technical field of lubricant processing, in particular to a lubricant mixing device. Background Art

[0002] During the production process of lubricants, different additives are often mixed into the base oil to improve the performance of the lubricant. For example, adding antioxidants can extend the life of the lubricant, and adding extreme pressure additives can improve the performance of the lubricant under heavy load conditions.

[0003] The mixing of lubricants and additives is mostly achieved by stirring, but the existing stirring mechanism can only perform simple one-way rotation stirring. One-way stirring easily causes local aggregation of materials in the mixing barrel and cannot achieve all-round uniform stirring, especially when dealing with lubricants with high viscosity, the uniformity of stirring is more difficult to ensure.

[0022] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. 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.

[0023] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed", "provided with", etc. should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. 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

[0024] See attached Figure 1-4 A lubricant mixing device comprises a mixing barrel 1, a top cover 2 is installed on the top of the mixing barrel 1, a discharge pipe 3 is connected to the bottom, and a feed pipe 4 is connected to the top cover 2;

[0025] A stirring rod 5 is also rotatably mounted on the top cover 2, and the stirring rod 5 extends into the mixing barrel 1 in the vertical direction. A gear 6 is fixedly mounted on the outer part of the top cover 2, and a rack 7 is meshed on the gear 6. The rack 7 is transmission-connected to a driving mechanism 8 provided on the top cover 2, and is driven to reciprocate along the tangential direction of the gear 6.

[0026] In this embodiment, after a certain proportion of lubricant and additive are added to the mixing barrel 1 through the feed pipe 4, the mixing is then stirred by the rotation of the stirring rod 5, and finally discharged from the discharge pipe 3, the mixing of the lubricant and additive is completed;

[0027] After the driving mechanism 8 drives the rack 7 to reciprocate along the tangential direction of the gear 6, the gear 6 will realize reciprocating rotation through the mutual engagement of the gear 6 and the rack 7, and the stirring rod 5 will synchronously reciprocate to realize two-way stirring, which can not only reduce the residual range of the stirring material and improve the mixing effect, but also the different stirring directions can generate shear force, so that the mixing of each part is more uniform, thereby ensuring the quality of the mixed material.

[0028] The outer wall of the mixing barrel 1 near the top is provided with a first thread 101 , and the first thread 101 and the second thread 201 provided on the inner wall of the top cover 2 match each other.

[0029] In this embodiment, the first thread 101 and the second thread 201 match each other, that is, the mixing barrel 1 and the top cover 2 are connected via threads, so that it is convenient to clean the mixing barrel 1 after removing the top cover 2.

[0030] The driving mechanism 8 includes a fixed plate 801, and there are two fixed plates 801. A guide slide rod 802 is fixedly installed between the two fixed plates 801. The guide slide rod 802 is slidably connected to the slide groove 701 opened at the end of the rack 7. A connecting rod 803 is hingedly provided on the side wall of the rack 7. The other end of the connecting rod 803 is connected to a disk 804. The disk 804 is eccentrically hinged to the other end of the connecting rod 803, and a motor 805 is installed at the center of the circle.

[0031] In this embodiment, after the motor 805 is started, the disc 804 rotates synchronously and drives the connecting rod 803 to pull the rack 7, so that the rack 7 slides back and forth on the guide rod 802 through the slide groove 701, thereby realizing the reciprocating motion of the rack 7 along the tangential direction of the gear 6.

[0032] A metal ring 9 is provided on the inner wall of the mixing barrel 1 . The metal ring 9 is hollow inside and provided with a resistance wire 10 . The gap between the resistance wire 10 and the metal ring 9 is filled with an insulating material 11 .

[0033] In this embodiment, the resistance wire 10 generates heat after being energized, and transfers the heat to the metal ring 9 through the insulating material 11. The metal ring 9 then transfers the heat to the mixed material in the mixing barrel 1, reducing its viscosity to avoid affecting the stirring effect.

[0034] 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.
