Abstract
The utility model relates to the technical field of sand blowers, and particularly relates to a sand production port of a sand blower. The sand production port comprises a flat sand production pipe; a mounting groove for the sand port to pass through is formed on the flat sand production pipe; an air inlet pipe is connected to the back end of the flat sand production pipe; one end of the air inlet pipe is wide and the other end thereof is relatively narrow; and the narrow end of the air inlet pipe is connected with the flat sand production pipe. The utility model utilizes airflow blown from a high-pressure positive blower to produce negative pressure in the air inlet pipe, so that the sand falling down from the sand port opening can be sucked and blown to the surface of the workpiece driven by the follow-up airflow, and the flow rate of the sand is limited, thereby reducing the power consumption and ensuring better processing effect. The surface of the processed workpiece has better uniformity and relative small glossiness deviation value.
Description
Technical field:
The utility model relates to the blowing machine technical field, particularly the blowing machine mouth that shakes out.
Background technology:
The most of employing of the machining equipment sandblast that the surface derusting on metal current or nonmetal plane, matt effect are handled, existing blowing machine, its mouth that shakes out generally is the flat pipeline, when workpiece is carried out Surface Machining, all adopts compressed air basically, drive moving of sand material, when the breadth of the same width of processing, because of power adopts compressed air, required power consumption is very big, and the uniformity of the surface of the work that processes and deviation of gloss amount are bigger.
The utility model content:
The purpose of this utility model is that the blowing machine mouth that shakes out is provided at the deficiencies in the prior art, and it can make blowing machine improve the Surface Machining uniformity, cut down the consumption of energy simultaneously.
For achieving the above object, the utility model adopts following technical scheme:
It comprises that flat goes out sandpipe, and flat goes out to offer the mounting groove that wears for the sand mouth on the sandpipe, and flat goes out the sandpipe rear end and is connected with blast pipe, and blast pipe one end broad, the other end are narrower, and a narrower end of blast pipe goes out sandpipe with flat and is connected.
Described mounting groove goes out the axis of sandpipe perpendicular to flat.
Described flat goes out also to offer the fixedly screw hole of sand mouth on the sandpipe.
The beneficial effects of the utility model are, utilization produces negative pressure from the air-flow that high pressure positive blower blows out at blast pipe, inhale the moving sand material that falls from sand mouth mouth, and under the promotion of follow-up air-flow, blow to surface of the work, the flow velocity of sand grains obtains restriction, thereby has reduced energy consumption on the one hand, makes that on the other hand processing effect is better, the uniformity of the surface of the work that processes is better, and the deviation of gloss amount is less.

Fig. 1 is a front view of the present utility model
Fig. 2 is a left view of the present utility model
Fig. 3 is a vertical view of the present utility model
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described.
The following stated only is a better embodiment of the present utility model, does not therefore limit protection domain of the present utility model.
See accompanying drawing 1-3, the utility model comprises that flat goes out sandpipe 10, go out sandpipe 10 and be flat, flat goes out to offer the mounting groove 12 that wears for the sand mouth on the sandpipe 10, owing to will cooperate the sand mouth of some, therefore go out to offer mounting groove 12 on the sandpipe 10 comparatively convenient, mounting groove 12 goes out the axis of sandpipe 10 perpendicular to flat, flat goes out sandpipe 10 rear ends and is connected with blast pipe 20, blast pipe 20 links to each other with outside blower fan, blast pipe 20 1 end broads, the other end are narrower, and a narrower end and the flat of blast pipe 20 go out sandpipe 10 and be connected.
Described flat goes out also to offer the fixedly screw hole 14 of sand mouth on the sandpipe 10.
The utility model utilization produces negative pressure from the air-flow that high pressure positive blower blows out in blast pipe 20, inhale the moving sand material that falls from sand mouth mouth, blow to surface of the work again under the promotion of follow-up air-flow, owing to be not to adopt compressed air to spray at a high speed, the sand material is restricted, flow velocity is relatively slow, so can improve uniformity to workpiece processing, certainly, when the sand mouth is installed, should guarantee as far as possible that also each sand mouth goes out evenly distributed on the sandpipe 10 at flat, improves the uniformity of processing.
The utility model can improve surface uniformity, the reduction deviation of gloss of blowing machine to workpiece, and when processing the workpiece of same width breadth, required energy consumption only is to adopt 1/2nd of sandblast processing.
