Abstract

The utility model relates to a sand blasting machine technical field, in particular to pressurization formula carousel sand blasting machine's fender sand curtain device in succession, it sets up the fender sand curtain board at dust removal pipeline dust absorption mouth including the polylith, keep off the wave plate board of sand curtain board for having a plurality of bends, the polylith keeps off the vertical setting side by side of sand curtain board, be equipped with the clearance between two adjacent fender sand curtain boards, because keep off the wave plate board of sand curtain device for having a plurality of bends, clearance space between two fender sand curtain boards forms tortuous passageway, the bounce-back number of times when having increased the sand material through these passageways, the energy of sand material motion has been consumed in a large number, make the sand material be difficult to rush out and keep off the sand curtain device, thereby it is the dust to make dust absorption pipeline take out, and the sand material then falls in the sand collection hopper of sand blasting machine, the fender sand curtain device keeps off sand is effectual.

Description

Sand-retaining curtain device of continuous pressurized rotary table sandblasting machine

Technical field:

The utility model relates to the technical field of sand blasting machines, in particular to a sand blocking curtain device of a continuous pressurized rotary table sand blasting machine.

Background technique:

The sandblasting machine uses compressed air as the power to form a high-speed jet beam to spray the spray material (shot peening glass beads, steel shot, steel sand, quartz sand, corundum, iron sand, sea sand) to the surface of the workpiece to be treated at high speed, so that The mechanical properties of the outer surface of the workpiece change, because the spray material has impact and cutting effect on the surface of the workpiece, so that the surface of the workpiece can obtain a certain degree of cleanliness and different roughness, and the mechanical properties of the workpiece surface are improved, thus improving the resistance of the workpiece Fatigue, increases the adhesion between it and the coating, prolongs the durability of the coating film, and is also conducive to the leveling and decoration of the coating. Sandblasting can remove impurities, variegated colors and oxide layers on the surface of the workpiece. At the same time, it roughens the surface of the workpiece, eliminates the residual stress on the surface of the workpiece and improves the surface hardness of the workpiece. However, when the sandblasting machine is performing sandblasting operations, the sand material often entrains dust, which affects the effect of sandblasting.

The existing sandblasting machine is equipped with a dust removal device. The dust removal device includes a fan, a dust removal box, and a dust suction pipe. Dust box. Because the fan will take away part of the sand when it sucks dust through the dust suction pipe, a sand-retaining curtain device is provided at the dust-absorbing port of the dust-absorbing pipe. It is a flat plate, which is inclined at the dust suction port. When the sand passes through the sand-retaining screen device, it only rebounds once through the sand-retaining screen. The energy consumption of sand movement is less, and some sand can still pass through the sand-retaining screen. The screen device is sucked away, and the sand blocking effect of the sand blocking screen device is poor.

Utility model content:

The purpose of the utility model is to provide a sand-blocking curtain device for a continuous pressurized rotary table sandblasting machine with good sand-blocking effect in view of the deficiencies in the prior art.

In order to achieve the above object, the utility model adopts the following technical solutions:

The sand-retaining curtain device of the continuous pressurized rotary table sandblasting machine includes a plurality of sand-retaining curtain plates arranged at the dust suction port of the dust removal pipeline. The sand-retaining curtain plates are corrugated plates with multiple bends. The sand-retaining curtain boards are vertically arranged side by side, and there is a gap between two adjacent sand-retaining curtain boards.

The corrugated plate is in the shape of a triangular tooth wave.

The bending of the corrugated plate is at an angle of 90 degrees.

The number of bends of the corrugated plate is 6.

The beneficial effects of the utility model are as follows: the utility model includes a plurality of sand-blocking curtain plates arranged at the dust suction port of the dust removal pipeline, the sand-blocking curtain plates are corrugated plates with multiple bends, and the multiple sand-blocking curtain plates are vertically Arranged side by side, there is a gap between two adjacent sand-blocking screens. Since the sand-blocking screen of the sand-blocking device is a corrugated plate with multiple bends, the gap between the two sand-blocking screens is formed. The tortuous channels increase the number of rebounds when the sand material passes through these channels, consume a lot of energy of the sand material movement, and make it difficult for the sand material to rush out of the sand blocking device, so that the dust suction pipe sucks away the dust, while the sand material Then it falls into the sand collecting bucket of the sandblasting machine, and the sand blocking effect of the sand blocking curtain device is good.

Description of drawings:

Fig. 1 is the structural representation of the utility model.

Detailed ways:

The utility model is further described below in conjunction with the accompanying drawings, see Fig. 1, the sand-retaining curtain device of the continuous pressurized rotary table sandblasting machine, which includes a plurality of sand-retaining curtain plates arranged at the dust suction port 5 of the dust removal pipeline 4 1. The sand-blocking curtain plate 1 is a corrugated plate with multiple bends 2. In this embodiment, the number of corrugated plate bends 2 is 6. Multiple sand-blocking curtain plates 1 are vertically arranged side by side, and two adjacent A gap 3 is provided between the sand retaining curtain panels 1 . The corrugated plate is in the shape of a triangular tooth wave, and the bending angle of the corrugated plate is 90 degrees.

Since the sand-blocking screen 1 of the sand-blocking screen device is a corrugated plate with multiple bends 2, the gap 3 between the two sand-blocking screens 1 forms a tortuous channel, which increases the rebound of the sand when it passes through these channels. The number of times consumes a large amount of energy of the movement of the sand material, making it difficult for the sand material to rush out of the sand retaining curtain device, so that the dust is sucked away by the dust suction pipe 4, and the sand material falls into the sand collecting bucket of the sandblasting machine. The sand screen device has a good sand blocking effect.

The above is only a preferred embodiment of the utility model, so all equivalent changes or modifications made according to the structure, features and principles described in the utility model patent application scope are all included in the utility model patent application scope .
