Description
Technical field
The utility model relates to a kind of workshop that is used for the sandblast operation.
Background technology
The carbon deposit of the oxide skin of mechanical industry forging and casting blank, scab, internal combustion engine all relies on sandblast to clear up, and this technology is promoted, yet that its significant drawback is labour protection is poor, and contaminated environment is serious.Sandblast workman continuous operation some months will be suffered from anthraco-silicosis.Therefore will thoroughly solve these two significant problems of sand-blast shop, technical must have significant innovation.
At first to thoroughly solve the labour protection problem.The fundamental way of head it off is to adopt isolated respiratory system to replace the filtering type respiratory system.The concrete structure of described isolated respiratory system can be the utility model patent of ZL200920259498.8 a kind of isolated respiratory system by name with reference to the patent No., and it comprises isolated breathing helmet 5 and system gas system.As shown in Figure 2, system gas system sterilizes outdoor air through chlorination equipment 24, supercharging device 25a, and 25b, 25c, 25d, the 25e supercharging, air filter 13 filters then, is transported in the isolated breathing helmet again and uses for the sandblast workman.For the clean air of certain pressure is provided in the isolated breathing helmet 5, guarantee that sand dust is blocked in outside the isolated breathing helmet 5 by system gas system.Yet the workman will take off isolated breathing helmet 5 when coming off duty, though sandblast this moment stops, indoor still sand dust fills the air, wait sand dust to make a decision and want half an hour at least, even sand dust makes a decision, in the air also with floating fine particle, if raise one's hat at shot blast cabinet this moment, must suck fine particle, therefore the infringement workers ' health must solve the problem that safety is raised one's hat.
Secondly to solve the post processing and the zero-emission problem of sand dust exactly, waste gas is carried out harmless processing, discharging is dropped to minimum level.
The utility model content
Poor to workman's protective capacities at existing sand-blast shop, the defective of contaminated environment of the present utility modelly aims to provide a kind of sand-blast shop, breathe under the unobstructed condition the workman, stop the injury of sand dust fully, and waste gas is handled, near zero-emission the workman.
The technical scheme that the utility model adopted is: make the preceding machine room of device of air in described sand-blast shop comprises, between scavenging, between shot blast cabinet and waste gas filtering; Be provided with big sliding door between between shot blast cabinet and scavenging, be provided with air-blast device between scavenging, its design feature is, be provided with the isolated breathing helmet that is communicated with gas making device in the preceding machine room in the described shot blast cabinet, be provided with air filter between waste gas filtering, between waste gas filtering the port of export of air filter be connected to be located at one bleed between in blower fan.
Among the present invention, the structure optimization of described gas making device is, the sterilization pipe that is in communication with the outside, this sterilization pipe be connected in series the pressure charging system that forms by the Pyatyi blower fan and be connected, the port of export of pressure charging system is communicated with described isolated breathing helmet by pipeline and air filter.
Why adopt Pyatyi blower fan serial connection, mainly be that tip speed is too fast and noise is excessive when preventing the supercharging of one-level blower fan, noise intensity is directly proportional with the blower fan tip speed, after adopting the Pyatyi blower fan, air pressure obtains increasing on the one hand, on the other hand, blower fan tip speeds at different levels are relatively low, avoid producing high noisy.
Further, in order to improve the condition of work of workman under severe cold and heat weather, be provided with air-conditioning in the described preceding machine room, the workman can breathe the gas of crossing through air-conditioning.
Described blower fan is a centrifugal fan, the gas after handling after filtration can be entered atmosphere, guarantees that the shot blast cabinet internal gas pressure is stable.
The workman will take off breathing helmet when coming off duty, though sandblast this moment stops, the fine particle in the sandblast still swims in the air, can not make a decision for a long time.If the workman raises one's hat at this moment, will suck trickle sand dust, year in and year out, the danger of the anthraco-silicosis suffered from is still arranged, and the method for head it off is to set up a clear area, the replacing clothing of in the clear area, raising one's hat.Therefore have scavenging port on described big sliding door, be provided with the second scavenging door between scavenging, the air-blast device that is located between scavenging is two desk fans, and wherein a power is bigger.Big sliding door is closed in the commentaries on classics of not stopping transport of small-power fan during work, and the scavenging port on the big sliding door is opened, and the second scavenging door is in closed condition, and the workman wears isolated breathing helmet work.The workman opens powerful fan earlier when coming off duty, and opens big sliding door then, has on breathing helmet and enters between scavenging, closes the scavenging port on big sliding door and the big sliding door afterwards rapidly.In the moment of opening big sliding door, have a certain amount of fine particle inevitably and scurry between scavenging, after entering between scavenging, the workman opens the second scavenging door again, the residual gas of scurrying between scavenging is carried out big fill.Treat that the fine particle expeling between scavenging is clean, the powerful fan unlatching duration is about 3～5 minutes in this process, takes off breathing helmet again, changes clothing and goes out.
Open the air-blast device scavenging, can stop that the sand dust of shot blast cabinet spreads on the one hand between scavenging, making becomes the clear area between scavenging; Can ventilate to shot blast cabinet on the other hand.
The utility model is exactly to adopt isolated respiratory system to replace the filtering type respiratory system specifically.Isolated respiratory system is to get gas away from the place of polluting, and is transported to breathing helmet through (also adopting air-conditioning when severe cold and heat) after sterilization, supercharging, the filtration by pipeline, and the workman wears the clean air that breathing helmet is breathed pressure.As long as air keeps certain pressure in the breathing helmet, promptly keep certain pressure reduction with environment, just sand dust can be forgone outside breathing helmet, thoroughly stop the harm of sand dust, and breathe unobstructed.Like this, the labour protection problem of sand-blast shop just obtains thoroughly, perfectly solves. and the method for sand-blast shop contaminated solution ring slope problem is that air is filtered---the papery cleaner that adopts the internal combustion engine industry generally to adopt, can filter sand dust more than 99%.Air after centrifugal fan will filter extracts, and enters atmosphere then.
The beneficial effects of the utility model: the utility model can be carried out omnidistance strength protection to the workman, breathing under the unobstructed condition, stops the injury of sand dust to the workman fully; Simultaneously waste gas is handled, blowdown is dropped to be close to zero, and waste gas treatment equipment is convenient to change, help environmental protection.Many industries such as the utility model also can be used for polishing, fluff cotton with sand and dust pollution.
