Description

Technical Field

[0001] This patent relates to the field of twin-shaft mixers, specifically a twin-shaft mixer. Background Technology

[0002] Mixers are mainly used for mixing materials such as cement, sand, gravel, and dry powder, blending multiple raw materials to produce materials of suitable viscosity or desired mixtures. There are many types of mixers, including forced mixers, single-shaft mixers, and twin-shaft mixers. Twin-shaft mixers typically use two parallel mixing shafts with mixing blades; during operation, the two shafts rotate synchronously to mix the materials.

[0003] However, existing twin-shaft mixers still have some shortcomings. For example, the mixing shaft is a wear part that often needs on-site repair and replacement. If the end plates at both ends of the tank are integrally welded, it will be very troublesome to replace the main shaft. Therefore, existing technologies need to be improved. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this patent is to provide a twin-shaft mixer.

[0005] The technical solution adopted by this patent to solve its technical problem is: a dual-shaft mixer, including a dual-shaft mixer body, the front end of the dual-shaft mixer body is provided with a drive position a and a drive position b, and the inner side wall of the dual-shaft mixer body is equipped with bearings corresponding to the drive positions a and b.

[0006] The bearing is equipped with a stirring shaft, and mounting grooves are provided at both drive position a and drive position b.

[0007] An installation plate is installed in the installation slot, and a through groove is opened in the installation plate. A sealed bearing is installed in the through groove.

[0008] A coupling is installed inside the inner ring of the sealed bearing;

[0009] The outer wall of the stirring shaft is uniformly fitted with clamps, and the outer wall of the clamps is fitted with stirring blades.

[0010] Furthermore, the mounting plate is installed in the mounting groove by means of a fixing structure. There are four fixing structures, which are distributed at the four corners of the mounting plate. Each fixing structure includes a mounting hole, a threaded hole, and a bolt.

[0011] Furthermore, the mounting hole is formed on the mounting plate, the threaded hole is formed on the body of the twin-shaft mixer, and the bolt passes through the mounting hole and is fitted into the threaded hole.

[0012] Furthermore, an L-shaped plate is installed at both drive position a and drive position b, and a servo motor is mounted on the L-shaped plate. The stirring shaft is connected to the servo motor via a coupling.

[0013] Furthermore, a U-shaped groove is provided on one side of the clamp, a screw is provided in the U-shaped groove, and a nut is screwed onto the screw.

[0014] Furthermore, a circular groove is formed on the internal thread of the nut, a circular part is placed in the circular groove, a threaded hole a is formed on the circular part, the bolt is sleeved in the threaded hole a, a retaining groove is formed on the circular groove, a retaining block is installed on the circular part, and the retaining block is engaged in the retaining groove.

[0015] Furthermore, a limiting groove is formed on the inner wall of the clamp, and a limiting block is provided on the outer wall of the stirring shaft, with the limiting block disposed within the limiting groove.

[0016] The beneficial effects of this patent are:

[0017] A twin-shaft mixer has a simple structure and is easy to operate. By setting mounting plates at the two drive positions of the twin-shaft mixer body, when repairing the mixing shaft, the bolts can be removed one by one. Then, the mounting plate can be taken out from the mounting slot, and the coupling can be taken out along with it, thereby removing the mixing shaft. This allows for quick and easy disassembly of the mounting plates for maintenance. Attached Figure Description
