Description

Equipment for improving distribution of pellets along width direction of blade by using external air flow

Technical Field

The utility model relates to a shot blasting cleaning, strengthening, shaping field specifically are equipment that utilizes plus air current to improve ball material and distribute along blade width direction.

Background

At present, a shot flowing pipe of the shot blasting machine only has a feed inlet. The pill material enters the pill flowing pipe from the feeding hole, flows along the inner wall of the pill flowing pipe under the action of gravity and finally gathers on one side of the pill distributing wheel far away from the pill flowing pipe. The pill material beam continuously impacts the side root of the pill wheel, so that the side root of the pill wheel is abraded too fast, and the early abrasion failure of the pill wheel is caused. And the pellets which are not fully dispersed fly out of the window of the directional sleeve after being accelerated by the pellet distributing wheel and are then carried by the blades, so that the window of the directional sleeve and the corresponding parts of the blades are intensively and excessively scoured and worn, premature wear failure is caused, and the service life of consumables is obviously shortened. In addition, the impact range of the shot materials concentrated on one side on the processed workpiece is obviously smaller than that of the shot materials when the shot materials are dispersed. That is, the current flow pellet tube structure results in: 1. premature failure of the impeller, the directional sleeve, the blades and the like; 2. the working efficiency of the impeller head is reduced.

Disclosure of Invention

The technical problem that this patent will be solved is: the concentrated pills are dispersed by using external air flow to improve the distribution of the pills along the width direction of the blades, and finally the problems in the background art are solved.

In order to achieve the purpose, the patent provides the following technical scheme:

an apparatus for improving the distribution of shot materials along the width direction of a blade by using external air flow is characterized by comprising a shot blasting machine bottom plate (14) fixed in a shot blasting chamber, the shot blasting machine bottom plate (14) is provided with a shot blasting machine shell (2) and a bearing seat (13), the shell (2) is connected with the cover cap (1), the periphery inside the shot blasting machine shell (2) is connected with the side protection plate (3) through bolts, the upper end of the side guard plate (3) is provided with a top guard plate (10), the right end of the shell (2) is connected with the front cover (5) through a bolt, the left end of the shell (2) is connected with a rear cover (11) through a screw, a main shaft (15) is arranged in the bearing seat (13), the right end of the main shaft (15) is connected with the linkage disc (12), the linkage disc (12) is connected with the pill distributing wheel (7), the linkage disc (12) is connected with the impeller II (16) through a screw, the impeller II (16) is connected with the impeller I (9) through a pin shaft (17), the impeller II (16) and the impeller I (9) are connected with the blades (4), the front cover (5) is connected with the directional sleeve (8), the directional sleeve (8) is connected with the pill flowing pipe (6), the upper end of the pill flowing pipe (6) is provided with a feeding hole, and the right side of the pill flowing pipe is provided with an air supplementing hole.

Compared with the prior art, the beneficial effect of this patent mainly embodies:

the existing impeller head has the problems that the pills in the pill flowing pipe are concentrated on one side of the pill distributing wheel far away from the pill flowing pipe under the action of gravity (at the moment, the influence of air on the pills is negligible), so that the pill distributing wheel on the side is worn too fast, and further, a directional sleeve and a vane on the same side are worn too fast to fail.

Adding an air supply port on the pipe wall of a shot flowing pipe of the shot blasting machine, blowing compressed air inwards through the air supply port, and allowing a large amount of shots to flow into the shot flowing pipe from a feed port of the shot flowing pipe and then move under the action of gravity; when the pellets pass through the air supply opening, the pellets are influenced by the external air-entrapping flow instead of the gravity of the pellets, and the pellets are blown out by the air moving at high speed, so that the pellets are more uniformly distributed in the axial direction of the pellet distributing wheel; thus reducing the impact wear degree of the pill materials to the side of the pill distributing wheel far away from the pill flowing pipe, delaying the wear failure time of the pill distributing wheel and further reducing the wear concentration degree of the directional sleeve and the blades on the same side; the pill materials accelerated by the pill distributing wheel are more dispersedly received by the vanes through the windows of the directional sleeve.
