Abstract

The utility model relates to a stirrer with dust suction material feeding mouth. A material feeding mouth with dust suction function is arranged on the stirrer. The material feeding mouth is provided with a double wall structure with an outer wall and an inner wall. The inner wall of the material feeding mouth is provided with a plurality of dust exhaustion pores. The outer wall of the material feeding mouth is fixed with a dust suction mouth which is connected with dust collector with capacity of generating negative pressure via a closed pipeline. The flying dust in feeding and stirring can be sucked into the dust collector through the dust suction mouth by the negative pressure produced by the dust collector. The utility model guarantees the cleaning of working environment, and is beneficial to environmental protection and body health of worker.

Description

The mixer of band dust suction dog-house

Technical field

The utility model relates to a kind of mixer, relate in particular to a kind of have effectively to reduce feed intake and the mixer of the band dust suction dog-house of stirring powder dust pollution.

Background technology

The existing mixer that is used for the refractory material stirring mainly comprises main drive gear, underframe, agitator, revolution revolving body, planetary gears, planetary stirrer, vortex slurry mixer and inside and outside scraper.Owing to adopted the compound stirring of whirlpool slurry and planet two kinds of forms, thus have stir, advantages such as main shaft stress balance, efficient height, no dead angle.But existing mixer still has the following disadvantages: in the process that feeds intake and stir, have a large amount of dusts and splash out from dog-house, polluted the environment of workplace, give workman's the healthy severe impairment of having brought.

Content of the present utility model

In order to solve above-mentioned the deficiencies in the prior art, the utility model provides a kind of mixer that has the dog-house of dust-absorbing function, can be when mixer evenly stirs refractory material apace, will feed intake and whipping process in the dust that splashed suck deduster by suction port, guaranteed the mixer dog-house of the cleaning of working environment.

In order to achieve the above object, on the mixer of the present utility model dog-house with dust-absorbing function is installed.Described dog-house is the double-wall structure with outer wall and inwall.Inwall at dog-house offers a plurality of dust exports.Fixed installation one suction port on the outer wall of dog-house, described suction port is connected by closed conduit with a deduster that can produce negative pressure.

Use mixer of the present utility model, the dust that can will splash when feeding intake and stirring utilizes principle of negative pressure to suck deduster by the suction port that is installed in dog-house.Guarantee the cleaning of working environment, environmental protection has been brought very big benefit, and helped the healthy of workman.

The specific embodiment

Below in conjunction with description of drawings embodiment of the present utility model.As Fig. 1, Fig. 2 and shown in Figure 3, mixer of the present utility model comprises housing 3, dog-house 2, water filling port 1.At the top of housing 3 water filling port 1 is installed, mixer of the present utility model is finished by water filling port 1 and is added water automatically, and can carry out quantitative water supply according to the requirement of technology, and can also to mixer in add warm water for the quality that guarantees to stir winter.Be provided with a fixed head 19 at the middle part of housing 3.

Reducing motor 7 is fixedly mounted on the bottom of housing 3.Stirring body 4 is installed on reducing motor 7.Stirring body 4 comprises main transmission gear wheel 41, travelling gear 42 and planetary gear 43.Wherein, main transmission gear wheel 41 is connected with the output shaft of reducing motor 7 and can be rotated by this output shaft, and travelling gear 42 is connected with a joggle with main transmission gear wheel 41, and planetary gear 43 is connected with a joggle with travelling gear 42.Planetary gear 43 and travelling gear 42 are installed on the fixed head 19.

The scraper 10 that seven groups of shapes, angle, positions have nothing in common with each other is installed on the main transmission gear wheel 41 of stirring body 4.Described scraper 10 revolves round the sun around the center of stirring body 4, and material is stirred.Axle head is equipped with three stirring pawls 5 of 120 ° of distributions at interval below planetary gear 43, and described stirring pawl 5 is done planetary motion with respect to main drive gear 41, not only does revolution but also do rotation.

When mixer is worked, rotate 41 rotations of drive main transmission gear wheel thereby drive reducing motor 7 by belt pulley 8, further drive scraper 10 and do the revolution rotation around the main shaft of main transmission gear wheel 41, the material in the mixer is overturn and promotes material advance.Planetary gear 43 is meshed with main transmission gear wheel 41 by travelling gear 42, promptly revolves round the sun and rotation with stirring body 4, drives stirring pawl 5 mounted thereto rotation again when doing revolution around the center of stirring body 4.Above-mentioned alr mode makes the material in the mixer obtain full and uniform stirring, and can significantly improve mixing speed.

The dog-house 2 of mixer of the present utility model can be installed in the either side on the left side or the right side of housing 3, comprises inwall 14 and outer wall 15.The top of inwall 14 and outer wall 15 is connected as a single entity.Outer wall 15 comprises top 15 ' and bottom 15 ".In one embodiment, top 15 ' and bottom 15 " fixedly connected by welding method.In another embodiment, top 15 ' and bottom 15 " also can form as one by the die casting mode.

Outer wall 15 is provided with a suction port 16, and the deduster (not shown) that described suction port 16 and can produce negative pressure is connected by closed conduit.Producing negative pressure principle and working method is prior art, no longer does elaboration here.

Thereby the dust export that communicates with suction port 16 in feed intake passage and inwall 14 and the space between the outer wall 15 that offer a plurality of connection inwalls 14 inboards on the inwall 14.In an embodiment as shown in Figure 1, equidistantly on the contour substantially circumferencial direction of inwall 14 and suction port 16 offer a plurality of dust exports 13.Preferably, dust export 13 is a thin-and-long, so both can prevent that the stirring material that drops into is sucked away, and can increase substantially the efficient and the effect of negative pressure dust suction again.The diameter of the part 15 ' that is provided with suction port 16 places of outer wall 15 is not provided with suction port 16 place's parts 15 greater than the bottom " diameter, can make the process of feeding intake more steady.

In one embodiment, a fixed head 17 is set in the bottom of inwall 14, fixed head 17 is by flange 17 ' and outer wall 15 " fixedly connected.On fixed head 17, offer a plurality of through holes 18.The dust that produces during stirring passes a plurality of through holes 18, via outer wall 15 " and inwall 14 between the space, be inhaled into the deduster from suction port 16.

When existing mixer is worked, when refractory material enters mixer by dog-house 2, can produce a large amount of dusts and splash out, so the dog-house of mixer is to cause working environment to pollute and the healthy pith of infringement workman by dog-house 2.Utilize dog-house of the present utility model, when mixer is worked because deduster produces negative pressure, the dust that produces be sucked out and be drained in the deduster by the dust export of offering 13 on inwall 14 by suction port 16.Thus, can solve weak point of the prior art effectively, guarantee the cleaning of working environment, help protecting that environment and workman's is healthy.

The above is specifying of embodiment of the present utility model only, is not to be used for limiting claim of the present utility model, and other all equivalent transformations that use technical characterictic of the present utility model to do all are included in the claim of the present utility model.
