Abstract

A sandblasting device includes a pressure equalizing air tank, a sand hopper and a spray gun. A sealing cover is provided on one end of the sand hopper; the entrance of the pressure equalizing air tank is connected to the compressor, the export is respectively connected to the sand hopper through the gas tube and the spray gun, the sand outlet of the sand hopper is connected to the high-pressure gas tube through the pipeline; the joint of the export of the pressure equalizing air tank to the sand hopper through the pipeline is higher than the sand plane height of the sand hopper design. As the cushioning action of the pressure equalizing air tank, the air pressure in the spray gun is always held the same, simultaneously, the pressure gas in the sand hopper drives the sand grains to uniformly fall to the sand outlet, to ensure the air pressure and sand grain homogeneity in the sandblasting process, to improve sandblasting processing effect. The sandblasting device overcomes the defect of the prior art that the sandblasting effect is influenced because the air pressure attenuation is non-uniform and the sand grain caking can not automatically outlet sand or the sand grain collapse can block the sand outlet. The utility model has simple and reasonable structure, uniform sand outlet and good sandblasting effect, can realize industrialization application and substitute the prior sandblasting device.

Description

A kind of sand blasting unit

Technical field

The utility model discloses a kind of sand blasting unit, belong to the metal surface treating device technical field.

Background technology

Sandblast (or spray pearl) be a kind of conventional means that metallic surface appearance is handled, (or the spray pearl) equipment that sandblasts commonly used generally is to be connected with sand inlet tube on spray gun and high-pressure air pipe that compressor directly links to each other, and the other end of sand inlet tube is connected with husky hopper sand outlet; Utilize flowing fast of spray gun high-pressure air pipe mesohigh gas, in sand output line, form the deadweight of the negative pressure and the grains of sand,, be sprayed onto the metal surface by spray gun with grains of sand sucking-off from husky hopper, the impact that the metal surface is produced certain energy, thus the Treatment of Metal Surface effect formed.Prior art is owing to only rely on negative pressure that gases at high pressure produce and the grains of sand are conducted oneself with dignity Sha Yuan is provided, in use, following problem occurs: 1, the high-pressure air pipe owing to spray gun directly links to each other with compressor, along with the spray gun open-interval is passed, the phenomenon of inhomogeneous decay appears in the pressure of gases at high pressure, causes the into inhomogeneous variation of husky amount; 2, the caking of the grains of sand in the husky hopper, appearance can not go out husky phenomenon automatically; 3, behind the caking of the grains of sand in the husky hopper, occur the phenomenon of avalanche accidentally, cause sand outlet to block; Above-mentioned all situations all can make processed metal surface can not form uniform striped, the effect that influence is sandblasted and handled.

The utility model content

The purpose of this utility model be to overcome the deficiency of prior art and provide a kind of simple and reasonable, go out husky evenly, effective sand blasting unit sandblasts.

The utility model is to adopt following proposal to realize: a kind of sand blasting unit, comprise all calm the anger jar, husky hopper, spray gun, and described husky hopper one end is a sand outlet, the other end is provided with seal cover; Described inlet of all calming the anger jar is connected with compressor, and outlet is connected with spray gun and husky hopper by tracheae respectively, and the sand outlet of described husky hopper is connected with the high-pressure air pipe of spray gun by pipeline.

In the utility model, described outlet of all calming the anger jar is higher than the sapin face height of described husky hopper design by the junction of pipeline and husky hopper.

The utility model is owing to adopt said structure, utilize the jar of all calming the anger that the gases at high pressure that compressor produces are all pressed, therefore, enter the cushioning effect of gases at high pressure in the spray gun because of all calming the anger jar, make air pressure in the spray gun remain one to, overcome the inhomogeneous decay of prior art air pressure, influenced the defective of the treatment effect that sandblasts; Simultaneously, gases at high pressure are introduced in the husky hopper of sealing, make the grains of sand in the husky hopper be under the certain pressure all the time, along with the unlatching of spray gun, the high pressure gas cognition in the husky hopper enters spray gun by sand outlet, thereby, drive the grains of sand and evenly fall to sand outlet thereupon together, overcome prior art grains of sand caking, can not go out the back avalanche of the sand or grains of sand caking automatically, blocked the defective of sand outlet; The effect defect of bad that sandblasts that has fundamentally solved air pressure and husky source instability and caused.

In sum, the utility model is simple and reasonable, go out husky evenly, sandblast effectively, can realize industrial applications, alternative existing blaster.

Description of drawings

Accompanying drawing 1 is the utility model structural representation.

Among the figure: the 1--jar of all calming the anger, the husky hopper of 2--, 3--spray gun.

The specific embodiment

Concrete structure of the present utility model describes in detail below in conjunction with drawings and Examples.

Referring to accompanying drawing, a kind of sand blasting unit of the utility model comprises all calm the anger jar 1, husky hopper 2, spray gun 3, and described husky hopper 2 one ends are sand outlet 4, and the other end is provided with seal cover 5; Described inlet of all calming the anger jar 1 is connected with compressor, and outlet is connected with spray gun 3 and husky hopper 2 by tracheae respectively, and the sand outlet 4 of described husky hopper 2 is connected by the high-pressure air pipe of pipeline with spray gun 3; The outlet of the described jar 1 of all calming the anger is higher than the sapin face height of described husky hopper 2 designs by the junction of pipeline and husky hopper 2.

When the utility model uses because the cushioning effect of all calming the anger jar, make air pressure in the spray gun remain one to; Simultaneously, the gases at high pressure in the husky hopper enter spray gun by sand outlet, drive the grains of sand and evenly fall to sand outlet thereupon together, have guaranteed the uniformity of air pressure, the grains of sand in the process that sandblasts, and have improved the effect that sandblasts and handle.

Claims

1. a sand blasting unit comprises all calm the anger jar, husky hopper, spray gun, it is characterized in that: described husky hopper one end is a sand outlet, and the other end is provided with seal cover; Described inlet of all calming the anger jar is connected with compressor, and outlet is connected with spray gun and husky hopper by tracheae respectively, and the sand outlet of described husky hopper is connected with the high-pressure air pipe of spray gun by pipeline.
