Abstract

The utility model discloses a mixer. The mixer comprises a rotor, an upper end cover, a case, a base and a rotating shaft, wherein the base is fixed on an equipment support; the rotor is connected with the rotating shaft; the base is connected with the upper end cover by the case; the lower surface of the upper end cover, the inner walls of the case and the upper surface of the base form a mixing chamber; lower stirring sticks are arranged on the upper surface of the rotor; upper stirring sticks and upper extrusion rings are arranged on the lower surface of the upper end cover; when rotating, the rotating shaft and the rotor drive the lower stirring sticks to rotate to stir materials; abrasion resistant rubbers are filled at the joints of the upper end cover and the case. The mixer can be applied to the technical field of plasterboard production to mix materials, and can avoid material stirring dead angles inside the stirring chamber so as to improve the overall mixing and stirring quality.

Description

A kind of mixer

Technical field

The utility model relates to gypsum board manufacture technical field, especially a kind of mixer.

Background technology

At present, in production process, the production line that relates to fluid operation is generally all provided with mixer.Mixer is to utilize mechanical force and gravity etc., the machinery that two or more material is evenly mixed.Mixer is widely used in all types of industries and daily life.As cement, sand, rubble and water are mixed into concrete wet feed etc.; Can also increase material contact surface area, to promote chemical reaction; Can also accelerate physical change, for example granular solute adds solvent, and the effect by mixing machinery can accelerate dissolution mix.

Conventional mixer inside is generally all provided with poking bar, and under the driving of motor, poking bar stirs various mixed materials.But because mixer volume is larger, inner stir chamber body space is larger, to such an extent as to can not effectively stir at the material at cavity edge, i.e. the whole stirring of material is even not, has directly affected mixing quality; Meanwhile, material is deposited in corner, cavity edge for a long time, also will directly affect the service life of mixer equipment.

Utility model content

The technical problem that the utility model solves is to provide a kind of mixer, can will carry out in time stirring operation in stirring the material at cavity edge, and whole mix and blend quality is high, and mixer service life of equipment is long.

For solving the problems of the technologies described above, the utility model provides a kind of mixer, it is characterized in that, comprises rotor, upper end cover, casing, base and rotating shaft, and described base is fixed on equipment frame;

Described rotor is connected with described rotating shaft, and described base connects described upper end cover by described casing, and described upper end cover lower surface and described casing inner wall, described base upper surface form mixing chamber;

Described rotor upper surface is provided with lower poking bar, and described upper end cover lower surface is provided with poking bar and upper extruding circle, and described rotating shaft and described rotor drive described lower poking bar to rotate and stir material while rotating;

Described upper end cover and described casing joint are filled with abrasive rubber.

Above-mentioned mixer also can have following features: described casing inner wall is provided with abrasion-proof backing block.

Above-mentioned mixer also can have following features: described rotor by flat key with described rotating shaft for being fixedly connected with;

Described rotating shaft is rotatably connected with described equipment frame by bearing.

Above-mentioned mixer also can have following features: described upper extruding circle is 5.5mm apart from described rotor upper surface.

Above-mentioned mixer also can have following features: described abrasive rubber is 5.5mm apart from described rotor upper surface.

The utility model such scheme has following beneficial effect:

1, the utility model can make to stir inside cavity and not leave the dead angle of stirring material, and whole mix and blend quality is high.

2, stirring cavity of the present utility model is provided with abrasion-proof backing block, stirs the long-time delay that cavity corner does not have material, longer service life.

Accompanying drawing explanation

Fig. 1 is embodiment mixer structural representation of the present utility model;

Fig. 2 is the utility model rotor scheme of installation.

The specific embodiment

For the ease of setting forth the utility model, below with reference to drawings and the specific embodiments, the enforcement of technical solutions of the utility model is described in further detail.

As Fig. 1, a kind of mixer that the utility model provides, comprises rotor 7, upper end cover 1, casing 13, base 11 and rotating shaft 8, and base 11 is fixed on equipment frame 12; Rotor 7 is connected with rotating shaft 8, and base 11 connects upper end cover 1 by casing 13, and upper end cover 1 lower surface and casing 13 inwalls, base 11 upper surfaces form mixing chamber; Rotor 7 upper surfaces are provided with lower poking bar 5, and upper end cover 1 lower surface is provided with poking bar 5 and upper extruding circle 4, and rotating shaft 8 drives lower poking bar 5 to rotate and stirs material while rotating with rotor 7, and upper end cover 1 is filled with abrasive rubber 3 with casing 13 joints.

Preferably, in the utility model embodiment, casing 13 inwalls are provided with abrasion-proof backing block 2; The setting of abrasion-proof backing block 2 can effectively improve the service life of mixer; Abrasion-proof backing block 2 for screw is connected, while finding that in use procedure the wearing and tearing of abrasion-proof backing block 2 are more serious, can directly be changed a new abrasion-proof backing block with casing 13, changes simple to operately, does not affect the operating efficiency of mixer.

Preferably, in the utility model embodiment, rotor 7 is fixedly connected with rotating shaft 8 by flat key 9; Rotating shaft 8 is rotatably connected with equipment frame 12 by bearing 10.Mixer is when work, rotating shaft 8 starts after driving by motor to rotate, rotating shaft 8 is rotated rotor driven 7 and is together rotated, the lower poking bar 5 and the abrasive rubber 3 that on rotor 7, arrange together start to rotate, now the fluid in mixing chamber starts to mix under stirring action, reaches the operation that qualified mixing quality stops mixer.

As shown in Figure 2, preferably, in the utility model embodiment, rotor 7 upper surfaces are evenly provided with the S-shaped arrangement of 5,12 lower poking bars 5 of 12 lower poking bars; Upper end cover lower surface is evenly provided with 6 upper poking bars.

Preferably, in the utility model embodiment, abrasive rubber 3 is 5.5mm apart from rotor 7 upper surfaces; Upper extruding circle 4 is 5.5mm apart from rotor 7 upper surfaces.The object that abrasive rubber 3 is set is like this for the non-cohesive fluid in corner, mixing chamber edge, and mixing chamber inside does not exist mixes dead angle.

In the utility model embodiment, abrasive rubber 3 has sticked on the corner of upper end cover 1 with casing 13, the fluid of mixing chamber inside can not stop in cavity corner because corner has the filling of abrasive rubber 3, the method of this filling abrasive rubber 3 can force fluid to be fully uniformly mixed between upper poking bar 6 and lower poking bar 5, to reach qualified mixing resultant.When there are most of wearing and tearing in abrasive rubber 3, directly open mixing chamber, refill and paste new abrasive rubber 3, simple to operate, be easy to later maintenance.

The mixer that the utility model provides can mix fluid well-distributing, reaches qualified mixing quality; Meanwhile, and in mixing chamber, be provided with abrasion-proof backing block, can effectively improve the service life of mixer.

In sum; these are only the utility model preferred embodiment; be not intended to limit protection domain of the present utility model; therefore; every any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model within spirit of the present utility model and principle.
