Description

A hybrid power mechanism

Technical Field

The utility model relates to the technical field of mixers, in particular to a power mechanism of a mixer.

Background Art

The gypsum board mixer is a device for mixing gypsum powder, water and auxiliary materials. The gypsum board mixer is continuously adding materials and then continuously discharging materials during operation. The existing mixer includes a casing and a rotor arranged inside the casing. Then, in order to prevent the gypsum slurry from caking on the rotor, a water inlet ring is fixedly connected to the top of the rotor. Process water is injected into the water inlet ring. The rotation of the rotor drives the water inlet ring to rotate so that the process water spreads outward and forms a water film on the top of the rotor. Then, the process water is mixed with the slurry inside the casing to complete the addition of process water. The process water is evenly spread, which is conducive to the uniform mixing of process water and slurry. At the same time, in order to prevent the slurry inside the casing from splashing to the top of the inner wall of the casing and condensing into lumps, a scraper is fixedly connected to the outer surface of the water inlet ring. The rotation of the water inlet ring drives the scraper to rotate to scrape off the slurry splashed on the top of the inner wall of the casing.

From the above, it can be seen that in the prior art, the water inlet ring is fixed on the rotor, and the scraper bar is fixed on the water inlet ring. The scraper bar, the water inlet ring and the rotor share a power source. The rotation speed of the water inlet ring is the same as the rotation speed of the rotor, and changes with the rotation speed of the rotor. The rotation speed of the water inlet ring cannot be regulated independently. Since the rotation speed of the water inlet ring is related to the industrial water inlet amount, the water inlet amount cannot be adjusted, which is inconvenient to adjust the viscosity of the prepared slurry.

Utility Model Content

DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

The water inlet ring in the prior art is fixed on the rotor, and the rotation speed of the water inlet ring is the same as the rotation speed of the rotor. The rotation speed of the water inlet ring cannot be adjusted independently. Since the rotation speed of the water inlet ring is related to the water inlet amount of industrial water, the water inlet amount cannot be adjusted, and it is not convenient to adjust the viscosity of the prepared slurry. Therefore, it is necessary to develop a power device that can independently adjust the water inlet amount of the water inlet ring.

As shown in FIG. 1 and FIG. 2 , the present invention provides a mixer power mechanism, which mainly controls the water intake amount of the water intake ring 2 by driving the water intake ring 2 solely through a reduction motor 5 .

The mixer power mechanism includes a rotor 1 and a water inlet ring 2 arranged on the top of the rotor 1, a rotating shaft 3 is fixedly connected inside the rotor 1, the water inlet ring 2 is arranged on the outer surface of the rotating shaft 3, and the water inlet ring 2 is rotatably connected to the rotating shaft 3 through a bearing, the rotor 1 is driven by a first motor 4, and the water inlet ring 2 is driven by a reduction motor 5, and the rotation speed of the water inlet ring 2 is adjusted by adjusting the rotation speed of the output shaft of the reduction motor 5.

In this embodiment, the rotor 1 is driven by the first motor 4, and the water inlet ring 2 is driven solely by the reduction motor 5. The water inlet ring 2 and the rotor 1 are driven by two power sources respectively. The speed of the water inlet ring 2 can be adjusted by adjusting the speed of the reduction motor 5, thereby adjusting the water inlet amount of the process water, and then adjusting the slurry viscosity, as well as the discharge speed and uniformity, without affecting the rotation speed of the rotor 1.

In actual use, the first motor 4 is started to drive the rotating shaft to rotate, thereby driving the rotor 1 to rotate, mixing and breaking the slurry, and the water inlet ring 2 is rotatably connected to the rotating shaft 3 through the bearing. The rotation of the rotating shaft 3 will not drive the water inlet ring 2 to rotate. The rotating shaft 3 supports and limits the water inlet ring 2. The reduction motor 5 is started, and the output shaft of the reduction motor 5 rotates to drive the water inlet ring 2 to rotate. The rotation speed of the water inlet ring 2 is adjusted by adjusting the rotation speed of the output shaft of the reduction motor 5, thereby adjusting the water intake amount, which facilitates the adjustment of the viscosity of the material.

The specific structure of the reduction motor 5 driving the water inlet ring 2 is that the top of the water inlet ring 2 is fixedly connected with a first pulley 6, the output shaft of the reduction motor 5 is fixedly connected with a second pulley 7, and the first pulley 6 and the second pulley 7 are driven by a belt 8. The output shaft of the reduction motor 5 rotates to drive the second pulley 7 to rotate, and the belt 8 drives the second pulley 7 to rotate, thereby driving the water inlet ring 2 to rotate, and adjusting the rotation speed of the output shaft of the reduction motor 5 adjusts the rotation speed of the water inlet ring 2.

In order to automatically control the amount of water intake and make the discharge more uniform, further, as shown in Figure 3, a viscosity sensor 9 is provided in the discharge pipe, and the viscosity sensor 9 and the reduction motor 5 are electrically connected to the controller 10. When the viscosity sensor 9 detects that the viscosity of the material is greater than the set value, the controller 10 increases the speed of the reduction motor 5, thereby increasing the amount of water intake. When the viscosity sensor 9 detects that the viscosity of the material is less than the set value, the controller 10 reduces the speed of the reduction motor 5, thereby reducing the amount of water intake.

By providing the viscosity sensor 9 and the controller 10, the speed of the reduction motor 5 can be automatically controlled according to the detected viscosity result, thereby controlling the speed of the water inlet ring 2, and finally adjusting the water inlet amount, and the viscosity of the material can be adjusted according to the characteristics of the material.

The viscosity sensor 924 is a SPC/L393 online viscosity sensor 924.

In order to remove the material splashed from the top of the inner wall of the casing, further, as shown in Figure 2, a scraper bar 11 is fixedly connected to the outer surface of the water inlet ring 2, and the top of the scraper bar 11 is in contact with the top of the inner wall of the casing. The speed of the scraper bar 11 is adjusted by adjusting the speed of the reduction motor 5.

The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
