Abstract
Provided is a movable type middling pressure breathing air supply device, belonging to the technical field of safe labor protection. The utility model aims to provide a movable device capable of continuously and stably supplying middling pressure breathing air, so that continuous and stable breathing air supply can be realized, the replacement of an air cylinder is not needed, the interruption risk of air supply is reduced, and the requirements for long-time and continuous air supply are satisfied. The movable type middling pressure breathing air supply device includes a vehicle frame, an air compressor, a primary filter, a filtering distributor, a standby high-pressure air bottle, a pipe coiling device, a control panel, and an air monitoring alarm. The device is connected with a breathing mask via a middling pressure tube to supply breathing air for people who works in a dangerous air condition and can be shut down at an emergency and sends acousto-optic alarm signals when the air nearby the air inlet of the device doesn't reach the standard, and the device can send acousto-optic alarm signals when the device is shut down due to failure and supplies standby breathing air for working staffs to evacuate from the operation post.
Description
Technical field
The utility model belongs to safe labour protection field; relate in a kind of movable type and to press the breathe air feedway, specifically a kind ofly continue to provide the safe labor protection device of middle pressure air draught to guarantee that people can eupnea in various hazardous areas.
Background technology
In the industrial department production processes such as oil, chemical industry, boats and ships, metallurgy and building materials and various forms of rescue and relief work process, often can use portable breathe air feedway.Common portable breathe air feedway is to use compressed air bottle as source of the gas, after the gas storage in gas cylinder is finished, need the artificial gas bomb of changing could continue air feed, change the gas bomb working strength large, required time is long, increase the air feed disruption risk, and need abundant bailout bottle, can not meet needs long-time in part producing process and rescue and relief work process, the sustainable supply breathe air.
Summary of the invention
The purpose of this utility model is to provide a kind of movable type can be continuously, press the device of breathe air in stable supply, thereby realize continuous, stable supplying breathe air, do not need to change gas bomb, reduce the air feed disruption risk, meet long-time, as to continue air feed requirement.
The technical solution of the utility model is as follows:
Press the breathe air feedway to comprise vehicle frame, air compressor, primary filter, filtering allotter, standby high pressure air bottle, coiling pipe bender, control panel and gas monitoring alarm in movable type of the present utility model.Vehicle frame comprises framework, base plate, handrail, wheel.Air compressor, primary filter, filtering allotter, standby high pressure air bottle, coiling pipe bender, gas-monitoring alarm, control panel are arranged on base plate.Primary filter comprises ball valve, oil water separator, main filter, oil removal filter.Filtering allotter comprises pressure-reducing valve, little oil strainer, charcoal absorption filter and the quick female of integrated form, and the quick female of integrated form is established 2 with upper outlet.Standby high-pressure air source comprises high pressure air bottle, pressure-reducing valve, automatic transfer valve.This device is equipped with coiling pipe bender, pressure pipe in all coiling on every cover coiling pipe bender.The gas-monitoring alarm can detect in air fuel gas and concentration of toxic gases and send the sound and light alarm signal when concentration over-standard.
The air compressor outlet is connected with the primary filter import, the primary filter outlet connects the filtering allotter import, one of two imports of automatic transfer valve on filtering allotter outlet and coiling pipe bender are connected, another import of automatic transfer valve is connected with high pressure air bottle, the automatic switchover valve outlet port is connected with the middle pressure pipe on coiling pipe bender, by middle pressure pipe, is breathing mask supply of breathing air.
The beneficial effects of the utility model are; can long-time continuous, uninterruptedly for the hazardous environment operating personnel provides stable breathe air, do not need to change gas cylinder; when near the air device air inlet, toxic gas or combustable gas concentration exceed standard; the device autostop; and send alarm signal; automatic transfer valve is switched to high pressure air bottle with air supply source when supply gas pressure is reduced to 0.5 MPa, for the operating personnel provides enough standby fresh air until withdraw the dangerous operation environment.
Description of drawings
Fig. 1 is the structural representation of facing of the present utility model.
Fig. 2 is backsight structural representation of the present utility model.
Fig. 3 is left TV structure schematic diagram of the present utility model.
Each parts in figure: 1. vehicle frame, 2. air compressor, 3. primary filter, 4. filtering allotter, 5. high pressure air bottle, 6. coiling pipe bender, 7. control panel, 8. gas-monitoring alarm.
The specific embodiment
Embodiment one:
The portable pneumatics breathe air of the utility model feedway is placed near circulation of air place setting, switches on power, middle pressure pipe is extracted out from (6) coiling pipe bender, be connected to breathing mask.
Turn on the power switch, power to device, wait for 2 to 3 minutes, (8) after the gas detection alarm normal operation, open the starting switch on (7) control panel, start (2) air compressor, after pressure is increased to 0.8 to 0.9 MPa, open (5) high pressure air bottle gas cylinder valve, the operating personnel has worn breathing mask, can start operation.
After operation is completed, first close (5) high pressure air bottle gas cylinder valve, then close the air compressor starting switch on (7) control panel, the shearing device power supply, pack up middle pressure pipe.
Embodiment two:
In operation process, when near the air device air inlet, fuel gas or toxic gas content surpassed required standard, (8) gas detection alarm was reported to the police, and automatic control system is cut off (2) air compressor power supply, and supply gas pressure reduces gradually.When supply gas pressure is reduced to 0.5 MPa, the transfer valve action, source of the gas is switched to (5) high pressure air bottle, by gas cylinder, is operating personnel's air feed, withdraws the breathe air guarantee that provides enough for the operating personnel.
Embodiment three:
In operation process, when electric or mechanical breakdown occurs, while causing (2) air compressor to shut down, (8) gas detection alarm is reported to the police and is sent the sound and light alarm signal.When supply gas pressure is reduced to 0.5 MPa, the transfer valve action, source of the gas is switched to (5) high pressure air bottle, by high pressure air bottle, is operating personnel's air feed, in order to withdraw the breathe air guarantee that provides enough for the operating personnel.
Claims (2)
1. press the breathe air feedway in a movable type, comprise vehicle frame, air compressor, primary filter, filtering allotter, standby high-pressure air feed source, coiling pipe bender, control panel and gas monitoring alarm, it is characterized in that: the air compressor outlet is connected with the primary filter import, the primary filter outlet connects the filtering allotter import, one of two imports of automatic transfer valve on filtering allotter outlet and coiling pipe bender are connected, another import of automatic transfer valve is connected with high pressure air bottle, the automatic switchover valve outlet port is connected with the middle pressure pipe on coiling pipe bender, be breathing mask supply of breathing air by middle pressure pipe.
