Description

Technical Field

[0001] This utility model relates to the field of cement additive production technology, specifically to a high-efficiency mixer for cement additives. Background Technology

[0002] Cement is a commonly used building material used to make concrete and mortar. It is a powdery substance composed of lime, silicon, aluminum, iron and other components as well as additives, and is produced through calcination and grinding. Cement additives require a mixer during processing. Currently, traditional twin-shaft mixers are commonly used for mixing cement additives, which severely restricts the increase in concrete production capacity due to their high production efficiency.

[0003] According to the description of a mixer disclosed on the patent website (authorization announcement number: CN209714939U), "This utility model discloses a mixer with the advantage that the position of the additive feeding pipe can be moved, which relates to the field of mixer technology. The mixer includes a housing, a connecting plate disposed in the housing, a turntable rotatably connected to the connecting plate, and a first motor disposed on the connecting plate and driving the turntable to rotate. The upper end of the housing is provided with a feeding pipe opposite to the center of the turntable, and the lower end is provided with a discharge port. The upper end of the housing is provided with an annular groove whose center is on the same vertical line as the center line of the turntable. An annular sliding plate that closes the groove is slidably connected in the groove. The sliding plate is provided with an additive feeding pipe that enters the housing and extends into the turntable. Each additive feeding pipe is provided with a material storage box at its upper end. The housing is provided with a drive component that drives the sliding plate to rotate."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] During use, this utility model drives the slide plate to rotate via a drive component, which in turn rotates the additive feeding pipe on the slide plate. This changes the position of the additive feeding pipe outlet within the turntable, facilitating the mixing of the additive and the material. However, in industrial production, companies often prioritize production efficiency. This device uses a drive turntable to rotate and mix materials through centrifugal force, resulting in a slow mixing speed. Furthermore, the device is protected internally by a casing, requiring the casing to be opened and the turntable removed to collect the finished product, which is inconvenient and affects production efficiency. Therefore, an improved, high-efficiency cement additive mixer is needed to solve these problems. Utility Model Content

[0030] Furthermore, the first stirring assembly 31 also includes a first motor 312, which is fixedly mounted on the outside of the mounting box 311. A first bevel gear 313 is fixedly mounted on the output end of the first motor 312. A third bevel gear 322 meshes with the first bevel gear 313, and a second bevel gear 315 meshes with the first bevel gear 313. By having the third bevel gear 322 mesh with the first bevel gear 313 and the second bevel gear 315 respectively, the first bevel gear 313 and the second bevel gear 315 rotate in opposite directions. The input end of the first motor 312 is electrically connected to an external power source.

[0031] Furthermore, the first rotating shaft 314 is rotatably installed inside the second rotating shaft 321, and the first rotating shaft 314 is rotatably installed inside the rotating bracket 323. The first rotating shaft 314 passes through the interior of the mixing tank body 1 and the mounting box 311, and drives the first stirring blade 316 to rotate through the first rotating shaft 314.

[0032] Furthermore, there are three sets of stirring blades 316, with an angle of 120° between each set, and two sets of stirring blades 324, with an angle of 180° between each set. The stirring blades 316 and 324 make the mixing in the device faster.

[0035] In actual operation, when this device is used, various raw materials are put into the inside of the mixing tank 1. The first motor 312 drives the first bevel gear 313 to rotate. The first bevel gear 313 meshes with the second bevel gear 315, so the second bevel gear 315 rotates synchronously. Under the action of the second bevel gear 315, the rotating shaft 314 rotates, driving the stirring blade 316 to stir the inside of the tank in the forward direction. At the same time, the first bevel gear 313 and the third bevel gear 322 mesh, so the third bevel gear 322 rotates synchronously in the reverse direction. Under the action of the third bevel gear 322, the rotating shaft 314 rotates. 1. The rotating bracket 323 is driven to rotate, which in turn drives the stirring blade 324 to stir the contents of the barrel in the opposite direction. The stirring blades 316 and 324 stir in opposite directions inside the barrel 1, making the additives in the barrel mix faster and more evenly. After mixing, the second motor 46 drives the first threaded rod 42 to rotate. Under the action of the synchronous belt 47, the second threaded rod 43 rotates synchronously, causing the sliding block 44 to move to the right. Under the action of the support rod 45, the barrel 1 rotates around the support bracket 5, causing the barrel opening to tilt downwards, making it easier to remove the mixed additives.
