Description
Technical field
A kind of sand washer of the utility model belongs to the sand washer technical field.
Background technology
Sand washer is the washing appliance of artificial sand or natural sand.Sand washer is widely used in the washings of industry to material such as sandstone field, mine, building materials, traffic, chemical industry, water conservancy and hydropower, concrete mixing plant.It can remove the impurity that covers the sandstone surface, destroys the steam layer that coats sand grains simultaneously, is beneficial to dehydration, plays efficient cleaning action.At present; Sand washer generally with motor through V-belt, decelerator, gear reduction after impeller slowly rotate; Because between decelerator and the gear, be between gear and the impeller spindle and be rigidly connected, in case after the sand washer overload; Be easy to the main shaft of sand washer is twisted off or the tooth of decelerator middle gear is destroyed, cause bigger loss.
The utility model content
The utility model overcomes the deficiency that prior art exists, and technical problem to be solved is that the sand washer that can not damage main shaft or decelerator after a kind of overload is provided.
In order to solve the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of sand washer; Comprise: motor, reducing gear, bearing block, impeller, main shaft and frame, impeller are fixed on the main shaft, and the two ends of main shaft are installed on the frame through bearing block and bearing respectively; The output shaft of motor is connected with the power shaft of reducing gear, and the output shaft of said reducing gear is connected with described main shaft through overload protection arrangement.
The structure of said reducing gear does; First input shaft of speed reducer is connected with the output shaft of said motor; The output shaft of first decelerator is connected with second input shaft of speed reducer, and the output shaft of second decelerator is connected with described main shaft through described overload protection arrangement.
Described overload protection arrangement or be safety coupling, or be overload-release clutch.
The below of said frame has osculum, and the diameter of said osculum is 350-450mm.
Described impeller is a double-row blades formula structure, is evenly equipped with a plurality of holes on the circle dividing plate between two row's blades.
The utility model compared with prior art has following beneficial effect.
1, is connected through safety coupling or overload-release clutch between the reducing gear in the utility model and the main shaft; During overload; Safety coupling or overload-release clutch can cut off getting in touch between reducing gear and the main shaft, thereby have protected decelerator and main shaft can not suffer damage, and have reduced loss.
2, the middle of the utility model used two decelerators to come motor is slowed down, and compares through belt, decelerator, a gear reduction with existing, avoided the belt wearing and tearing, the problem that the open pinion drive gear life-span is short.
3, the osculum increasing diameter of the utility model mid frame below 350-450mm greatly makes draining easier.
4, the utility model perforate on dividing plate is broken down when shutting down, and can in the hole, penetrate stay cord, spurs stay cord then and makes and wheel rotation go out the surplus sand in the washed-out sand groove clearly, is convenient to start next time.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the vertical view of Fig. 1.
Among the figure: 1 is motor, and 2 is reducing gear, and 3 is bearing block, and 4 is impeller, and 5 is main shaft, and 6 is frame, and 7 is bearing, and 8 is overload protection arrangement, and 9 is first decelerator, and 10 is second decelerator, and 11 is osculum, and 12 is blade, and 13 is the hole, and 14 is dividing plate.
The specific embodiment
Shown in Figure 2 like Fig. 1; A kind of sand washer of the utility model; Comprise: motor 1, reducing gear 2, bearing block 3, impeller 4, main shaft 5 and frame 6, impeller 4 are fixed on the main shaft 5, and the two ends of main shaft 5 are installed on the frame 6 through bearing block 3 and bearing 7 respectively; The output shaft of motor 1 is connected with the power shaft of reducing gear 2, and the output shaft of said reducing gear 2 is connected with described main shaft 5 through overload protection arrangement 8.
The structure of said reducing gear 2 does; The power shaft of first decelerator 9 is connected with the output shaft of said motor 1; The output shaft of first decelerator 9 is connected with the power shaft of second decelerator 10, and the output shaft of second decelerator 10 is connected with described main shaft 5 through described overload protection arrangement 8.
Described overload protection arrangement 8 or be safety coupling, or be overload-release clutch.
The below of said frame 6 has osculum 11, and the diameter of said osculum 11 is 350-450mm.
Described impeller 4 is a double-row blades formula structure, is evenly equipped with a plurality of holes 13 on the circle dividing plate 14 between two row's blades 12.
In the utility model, impeller 4, frame 6 are prior art.
In the utility model, the safety coupling that uses can be the shear pin safety coupling, and the overload-release clutch that uses can be the ball overload-release clutch.
Reducing gear 2 in the utility model can replace with a cycloidal-pin wheel decelerator.
The course of work of the utility model is: motor 1 slows down through reducing gear 2, and the back drives main shaft 5 and impeller 4 slowly rotates, and sandstone is got in the washing trough by feeder trough, under the drive of impeller 4, rolls; And grind mutually, remove the impurity that covers the sandstone surface, destroy the steam layer that coats sand grains simultaneously; Be beneficial to dehydration, add water simultaneously, form strong current; In time impurity and the little foreign matter of proportion are taken away, and discharged, accomplish and clean from the overfall of washing trough; Clean sandstone is taken away by blade 12, and last sandstone is poured blow tank into by the impeller 4 of rotation.When the sandstone in the washing trough transshipped too much, safety coupling or overload-release clutch will break off getting in touch between reducing gear 2 and the main shaft 5, and protection main shaft 5 can not be damaged with decelerator.At this moment, as long as turn off power supply, unnecessary sandstone cleaned out washing trough after, restart motor 1 and get final product.
The utility model can be widely used in occasions such as construction site, sandstone factory, concrete dam building site, power station.
