Description
Technical Field

Background
The shot blasting machine is a processing technology for throwing steel grit steel shots at high speed to impact the surfaces of material objects through a shot blasting machine. It is faster, more efficient than other surface treatment techniques, and can be used for part retention or casting processes after stamping. The first shot-blasting machine was made in the world by united states corporation in the 30's of the 20 th century. The production of the shot blasting strengthening equipment in China begins in the 50 s of the 20 th century and mainly simulates the former Soviet Union technology. Shot blasting machines may also be used to remove burrs, membranes, and rust that may affect the integrity, appearance, or definition of portions of an object. The shot blasting machine can also remove pollutants on the surface of a part of coating and provide a surface profile for increasing the adhesive force of the coating, so as to achieve the purpose of strengthening the workpiece. Shot blasting machines differ from shot blasting machines in that they are used to reduce the fatigue life of the part, increase differential surface stresses, increase the strength of the part, or prevent fretting. The separator is a key system of the shot blasting machine equipment.
Almost all steel castings, gray castings, malleable iron castings, ductile iron castings, etc. are shot-blasted. The method is not only used for removing oxide scales and bonded sand on the surface of the casting, but also is an indispensable preparation process before the quality inspection of the casting, for example, a large-sized turbine shell needs to be strictly cleaned by throwing and spraying shots before nondestructive inspection is carried out, so that the reliability of the inspection result is ensured. In the production of general castings, shot blasting cleaning is an essential technological means for finding casting surface defects such as subcutaneous blowholes, slag holes, bonded sand, cold shut, peeling and the like. The surface cleaning of non-ferrous metal castings, such as aluminum alloy, copper alloy and the like, not only removes oxide scale and finds surface defects of the castings, but also mainly aims at removing burrs of die castings and obtaining surface quality with decoration significance by shot blasting and obtaining comprehensive effects. In metallurgical steel production, shot blasting or pickling is a mechanical or chemical combined process for removing phosphorus scale to ensure high productivity in steel mass production. In the production of other alloy steel plates and strips such as silicon steel sheets, stainless steel sheets and the like, shot blasting or acid pickling treatment is carried out after annealing in the cold rolling process so as to ensure the surface roughness and the thickness precision of the cold-rolled steel sheets. The quality of the separation effect is directly related to the cleaning effect of the shot blasting machine and the service life of the wearing parts, when the sand content of shot in the bin is 2%, the shot blasting effect is poor, dust is attached to the surface of a shot-blasting component, the abrasion speed of blades of the shot blasting machine is increased by 5-10 times compared with that of pure steel or iron shot, and the abrasion of other wearing parts is also intensified to different degrees.

It is contemplated that some or even all of the good pellets may be manually or robotically placed into the elevator and then transported by the elevator to the pellet inlet 210 for circular screening.
Specifically, the dust collector further comprises an inner baffle 500, wherein the inner baffle 500 is positioned above the inlet of the dust channel 230 and is vertically connected with the triangular separation plate 420, and one end of the inner baffle 500, which is far away from the triangular separation plate 420, extends towards the inner side of the inlet of the dust channel 230, so that transversely-floating dust collides with the surface of the inner baffle, loses transverse power and falls down into the dust channel 230.
More specifically, the 500 positions of the inner baffle are L-shaped; the effective fixing area is increased to improve the fixing firmness.
The technical scheme of the embodiment at least has the following technical effects or advantages:
in the above technical solution, as the separating mechanism 400 composed of the separating bin 410, the triangular separating plate 420, the adjusting assembly 430, the air inlet 440, the air duct 210, the air outlet 220, the two discharging channels 450 and the two dust channels 230 is arranged below the feeding assembly 300, the adjusting assembly 430 composed of the handle 431 penetrating through the outer wall of the triangular body 120, the steel plate 433 and the stainless steel round bar 435 is combined; wherein, one end of the handle 431 is connected with the steel plate 433 so as to adjust the angle of the steel plate 433; the stainless steel round rod is arranged at one end, far away from the handle 431, of the steel plate 433, the surface of the stainless steel round rod is close to the outer surface of the triangular separation plate 420, the stainless steel round rod 435 can be driven by the adjusting handle 431 to adjust the gap between the stainless steel round rod 435 and the triangular separation plate 420, and then a series of technical means such as a dust removal fan and the like are combined, so that on one hand, the flow rate of the shot sand waterfall flow is controlled by adjusting the gap between the stainless steel round rod 435 and the triangular separation plate 420 through the handle 431; on the other hand, when the negative pressure air enters from the air inlet 440, flows through the air duct 210, and then flows out from the air outlet 220, 2 continuous air flows from the outside to the inside are formed, the shot in the shot-sand waterfall flow falls to the discharging channel 450 under the weight of the shot by utilizing the gravity air separation principle, and the metal scale fragments, the broken shot, the dust and the fine shot are far lighter than the shot and transversely float for a section of stroke and fall to the dust channel 230 under the action of the air flow, so that the separation of the waste and the shot is realized. The technical problem that the shot blasting machine cannot effectively separate dust in the prior art is effectively solved, and the technical effects of improving the stability of the steel shot flow curtain and improving the dust separation efficiency are further achieved.
On the basis of the above, the combination of the inner baffle 500 which is positioned above the inlet of the dust channel 230 and vertically connected with the triangular separating plate 420 is adopted as a technical means, so that the transversely floating dust loses transverse power after colliding to the surface of the dust channel and falls down into the dust channel 230, and the risk that the dust is discharged into the air after passing over the inlet of the dust channel 230 and entering the air channel 210 along with the air flow is reduced; the technical problem that the shot blasting machine cannot effectively separate dust in the prior art is better solved, and the technical effect of improving the dust separation efficiency is further realized.
The utility model discloses technical scheme's spare part all can be used commonly the regular spare part in the market and assemble.
