Abstract

The utility model provides a continuous operation sand blaster, which aims to eliminate the technical defects of the prior continuous operation sand blaster, reduce the fault rate and improve the operation efficiency. The technical proposal is as follows: a cylinder push type mushroom-head valve is used to seal an upper bin and a lower bin of the sand blaster; the mushroom-head valve adopts a rubber mushroom head with quite large rubber lining area; a fixed sealing ring is made of metal; a rubber skin pipe type pinch valve serves as the sand outlet valve of the sand blaster; the rubber skin pipe is in a straight-through structure, has consistent direction with the sand flow, and is not provided with any outer cover; and pneumatic ball valves with good universal performance are adopted by other air circuit control valves. The continuous operation sand blaster avoids the phenomenon of seizure, thereby thoroughly solving the sealing problem of the mushroom-head valve, eliminating commonly seen faults of not smooth sand outlet, easy block and the like, really realizing continuous operation, greatly improving the operation efficiency of the sand blaster; and the equipment has simple structure, the used accessories have strong universality, and the maintenance and the replacement are convenient.

Description

The sand-blasting machine of working continuously

Technical field

The utility model relates to the surface derusting of metal material and hardware, the treatment facility that eliminates stress, and is specifically related to a kind of sand-blasting machine of working continuously.

Background technology

The sand-blasting machine of working continuously at present is to adopt two chamber structures, and the mushroom in a upper and lower storehouse seal valve is to promote the mushroom head by the air inlet pipe at the bottom of the valve to close, and opens unpoweredly, is fully by the gravity realization.Head is generally metal material owing to pester, and the fixing seal ring is the line with rubber material, appears at the head of pestering when opening and pushes too tight and phenomenon that block with the fixing seal ring; Because the diameter space of sealing ring is restricted, line with rubber can not area do too much, thereby often wear and tear, fault such as fracture, the destruction sealing; The valve that shakes out is special-purpose angie type diaphragm valve, and the angie type structure makes to shake out and is not very smooth and easy, and valve is fragile, and fault rate is very high; Other gas circuits are employed all to be special-purpose pneumatic diaphragm valve, the fault rate height, and versatility is bad.

Summary of the invention

The utility model provides a kind of sand-blasting machine of working continuously, and purpose is exactly to eliminate the technological deficiency that the existing sand-blasting machine of working continuously exists, and reduces fault rate, improves operating efficiency.

The technical scheme that the utility model is taked reaches the sealing between the storehouse up and down and all adopts cylinder driving mushroom head valve door sealing in storehouse on the sand-blasting machine; Mushroom head valve door adopts the big slightly rubber mushroom head of line with rubber area, and the fixing seal ring adopts metal material; The valve that shakes out of sand-blasting machine adopts rubber tubular type pinch valve, and hose is a bypass structure, and is consistent with the sand flow direction, and hose does not have overcoat; Last storehouse air inlet pneumatic operated valve, go out gas path control valve doors such as sandpipe pneumatic operated valve, all adopt the good pneumatic ball valve of universal performance.

The utility model compared with prior art owing to adopt cylinder driving mushroom head valve door, has been stopped stuck phenomenon, has reduced fault rate; Because a mushroom line with rubber area that adopts is big slightly, has thoroughly solved mushroom head valve door sealing problem; Valve employing rubber tubular type pinch valve has been eliminated the fault of the frequent appearance such as having some setbacks, easily stop up of shaking out owing to shake out, and has really realized working continuously, and has improved the operating efficiency of sand-blasting machine greatly; Device structure is simple, used accessory highly versatile, convenient maintenance and replacement.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:

Fig. 1 is the sand-blasting machine structural representation of working continuously;

Fig. 2 is a cylinder seal formula mushroom head valve door schematic diagram;

Fig. 3 is the state diagram of glue pipe type pinch valve structure chart and open and close;

Fig. 4 is that the glue pipe type pinch valve is opened, closing state figure.

Symbol description among the figure: safety valve 1, go up storehouse air inlet pneumatic ball valve 2, go out sandpipe pneumatic ball valve 3, go up storehouse cylinder seal formula mushroom head valve door 4, go up silometer 5, storehouse cylinder seal formula mushroom head valve door 6, silometer 7, rubber tubular type pinch valve 8, spray gun 9, mushroom 10, fixing seal ring 11, cylinder 12, sealing flange 13, hose 14, cylinder fixed bar 15, cylinder 16, compression column with fixed 17, movable depression bar 18 down down.

The specific embodiment

As shown in Figure 1, work continuously sand-blasting machine by safety valve 1, go up storehouse air inlet pneumatic ball valve 2, go out sandpipe pneumatic ball valve 3, go up storehouse cylinder seal formula mushroom head valve door 4, go up silometer 5, down storehouse cylinder seal formula mushroom head valve door 6, the valve that shakes out of silometer 7, sand-blasting machine constitutes with rubber tubular type pinch valve 8, spray gun 9 and upper and lower feed bin etc. down.When working continuously the sand-blasting machine operation, cylinder 12 (see figure 2)s of sand-blasting machine promote to go up storehouse cylinder seal formula mushroom head valve door 4 and 6 sealings of following storehouse cylinder seal formula mushroom head valve door.The benefit that adopts cylinder to promote is, avoid pestering the head valve door when opening since with the too tight fault of blocking of fixing seal ring extruding.

As shown in Figure 2, for faults such as the wearing and tearing that prevent the sealed line with rubber structure, fractures, destroy sealing, the material that adopts in mushroom 10 and fixing seal ring 11 original structures is exchanged, it is main because mushroom 10 a residing space are bigger, mushroom 10 an employing rubber structure can strengthen the area of sealed line with rubber structure, and are just not fragile, and use fixing seal ring 11 instead metal structure; It is the shape that changes the line with rubber structure that this material exchanges purpose, promptly increases area, and does not relate to the performance of utilizing material.And the mushroom head can wholely take out when changing parts, and is very convenient.

As shown in Figure 3 and Figure 4, rubber tubular type pinch valve 8 is made of sealing flange 13, hose 14, cylinder fixed bar 15, cylinder 16, compression column with fixed 17, movable depression bar 18.Hose 14 is a bypass structure and wear-resisting, and is consistent with the sand flow direction, unless sebific duct 14 wearing and tearing other fault can not occur.Push away or draw 18 extruding of movable depression bar or unclamp by cylinder 16, change hose 14 shapes, realize the pass of valve or open; This structure glue leather hose does not have overcoat, changes very convenient.

Last storehouse air inlet gas circuit, the by-pass valve control that goes out the sandpipe gas circuit adopt the good storehouse air inlet pneumatic ball valve 2 of universal performance respectively, go out sandpipe pneumatic ball valve 3, ball valve sealing performance height and stable performance, and fault rate is extremely low.

The hose 14 that sand flow is unclamped through rubber tubular type pinch valve 8 by following storehouse (sees that Fig. 4 a) flows downward, under the blast effect that goes out 3 controls of sandpipe pneumatic ball valve, by spray gun 9 ejections; When cylinder 16 promotion activity depression bars 18 extruding hoses 14 (seeing Fig. 4 b), hose 14 is closed and is held back sand flow, and spray gun 9 stops sandblast.
