Embodiment 1

[0018] Such as figure 1 As shown, this embodiment includes a box body 1, a sandblasting pipe 2 and a nozzle 3, the box body 1 is provided with an air intake control valve 4 and an exhaust control valve 5, and the sand outlet at the bottom of the box body 1 is installed with a Butterfly sand control valve 6, one end of sandblasting pipe 2 is connected to box body 1 through air intake control valve 4, and the other end is connected to butterfly sand control valve 6 and nozzle 3 respectively through thickened sand outlet tee 7, and also includes The exhaust muffler arranged on the exhaust control valve 4; the external air source enters the box body 1 and the sandblasting pipe 2 respectively through the air intake control valve 4 under the filtering action of the filter, and as the inside of the box body 1 As the air pressure increases, the abrasive in the box 1 reaches the butterfly sand control valve 6 under the push of atmospheric pressure, and the butterfly sand control valve ...

Embodiment 2

[0020] Such as figure 1 As shown, on the basis of Embodiment 1, this embodiment also includes an observation port 8 arranged in the middle of the box body 1 , and tempered glass is installed on the observation port 8 . An observation port 8 is set in the middle and lower part of the box body 1, which allows the operator to check the remaining amount of abrasive at any time, which is convenient for adding abrasive in time to ensure sandblasting efficiency; the installation of high-strength tempered glass can avoid abrasive Continuous impact on the observation port 8 will cause the glass to break.

Abstract

The invention discloses a sand blasting machine. The sand blasting machine comprises a box body, a sand blasting pipe and a nozzle, wherein the box body is provided with an air feeding control valve and an air exhausting control valve; a sand outlet in the bottom part of the box body is provided with a butterfly-shaped sand adjusting valve; one end of the sand blasting pipe is connected with the box body by the air feeding control valve; and the other end of the sand blasting pipe is connected with the butterfly-shaped sand adjusting valve and the nozzle respectively by a thickened sand discharging tee joint. Abrasive materials in the box body reach the thickened sand discharging tee joint through an inner structure of the inclined butterfly-shaped sand adjusting valve under the pushing of air pressure, and the thickened sand discharging tee joint and the butterfly-shaped sand adjusting valve are independently arranged and are improved to increase the wall thickness of the bottom part, so that the abrasion time is prolonged; meanwhile, a sand falling opening in the tee joint is changed into a 45-degree inclined angle from an original 90-degree vertical angle, so as to form an airflow path in the same direction with a rear airflow; and the effective power of particles in the sand valve is increased, the rebound and rotation of sand particles at the bottom of the sand valve are reduced, and the abrasion to the sand discharging tee joint and the sand spraying pipe is reduced, so that the utilization rate of the equipment is increased.

Description

technical field [0001] The invention relates to the field of mechanical production, in particular to a sandblasting machine. Background technique [0002] The structural principle of the sandblasting machine is to use compressed air to transport sand powder particles from the sand storage tank of the equipment to the surface of the object to be sandblasted and polished. This process is called sandblasting, and its main function is to improve the surface of the object. rough state. The key points to determine the sandblasting effect of the sandblasting machine are: suitable sand flow and suitable compressed air flow. The size of the compressed air determines that the flow velocity in the pipe should be greater than the sedimentation velocity of the maximum sand flow process of the sandblasting machine. The aerodynamic force is sufficient to control the friction loss and the sum of the resistance of the sand in the pipe, which can ensure the smooth flow of the sand in the pip...
