Description
Technical Field
The utility model relates to a sandblast protective helmet for in the colliery, especially an adjustable helmet of dust proof malleation.
Background
At present, a positive pressure respirator is mostly adopted to provide clean air for a driver of the fully-mechanized excavating machine. But there are drawbacks to positive pressure respirators:
1. air supply is carried out by adopting a compressed air pipeline during tunneling, and an air supply hose needs to be connected in a delayed manner according to the tunneling progress;
2. the front-back movement range of the roadheader is long, a long air supply hose needs to be connected in an extending mode to meet production requirements, and the pipeline is troublesome to retract and release;
3. the air quality in the compressed air pipeline is poor, and the compressed air pipeline contains more harmful gases.
Disclosure of Invention
The invention aims to overcome the defects of the existing positive pressure respirator and provide a dust-proof positive pressure adjustable helmet.
In order to accomplish the object of the present invention, the present invention adopts the following technical solutions:
the utility model discloses an adjustable helmet of dust proof malleation, it includes: sandblast protection helmet, protect neck, air temperature regulator and air purifier, with protect the neck and link to each other on the circumference of sandblast protection helmet lower extreme, wherein: the upper part of the air purifier is connected with a high-pressure air inlet pipe, the lower end of the air purifier is connected with a water outlet pipe, the air purifier is connected with the air inlet end of an air temperature regulator through an air outlet pipe, an air inlet valve and a pressure gauge are arranged on the air outlet pipe, the air outlet end of the air temperature regulator is connected with a sand blasting protection helmet through a helmet air inlet pipe, and a fan is arranged in the air temperature regulator.
The utility model discloses an adjustable helmet of dust proof malleation, wherein: the air purifier is a solid steel cylinder.
Compared with the prior art, the utility model discloses a dust-proof positive pressure adjustable helmet has following advantage
1. The utility model discloses utilize solid steel bottle storage fresh air, it is convenient to remove.
2. The stored air is effectively filtered, impurities are removed, and the air purifier is safer to use.
3. The air temperature adjusting device enables a driver of the roadheader to breathe more smoothly during operation, and the driver does not feel oppression in chest and blurred vision caused by exhalation.

in fig. 1, reference numeral 1 denotes a high-pressure intake pipe; the reference numeral 2 is a water outlet pipe; reference numeral 3 is an air cleaner; reference numeral 4 is an intake valve; reference numeral 5 is a fan; reference numeral 6 is an air temperature regulator; reference numeral 7 is a sandblasting protection helmet; the label 8 is neck protector; reference numeral 9 is an outlet pipe; reference numeral 10 is a helmet air inlet pipe; reference numeral 11 denotes a pressure gauge.
Detailed Description
As shown in fig. 1, the utility model discloses an adjustable helmet of dust proof malleation includes: sandblast protection helmet 7, protect neck 8, air temperature regulator 6 and air purifier 3, with protect neck 8 and link to each other on the circumference of sandblast protection helmet 7 lower extreme, air purifier 3's upper portion links to each other with high-pressure intake pipe 1, and air purifier 3's lower extreme links to each other with outlet pipe 2, and air purifier 3 passes through outlet duct 9 and links to each other with air temperature regulator 6's inlet end, and air purifier 3 is the solid steel bottle. An air inlet valve 4 and a pressure gauge 11 are arranged on an air outlet pipe 9, the air outlet end of an air temperature regulator 6 is connected with a sand blasting protective helmet 7 through a helmet air inlet pipe 10, and a fan 5 is arranged in the air temperature regulator 6.
The utility model discloses an adjustable helmet of dust proof malleation mainly comprises air purifier 3, air temperature regulator 6, sandblast protection helmet 7 triplex. The air purifier 3 separates out water impurities, grease and other substances in the compressed air; can adjust air temperature regulator 6's the temperature of giving vent to anger through adjusting admission valve 4, can realize the effective regulation of the machine driver of integrating breathing air temperature and sandblast protection helmet internal environment temperature, the driver can be according to the temperature resistant degree of oneself and independently adjust, promptly: when the pressure of the compressed air is 0.4-0.7MPa, the temperature is adjusted to 10-40 ℃. The sand blasting protective helmet adopts double-layer membrane protection, a high-quality air guide hose, good sealing performance and convenient and fast sand blocking piece replacement. The device can also realize flexible conversion between two air supply modes of an air temperature regulator or common air, and is extremely humanized.
The method comprises the following operation steps: before cutting the kiln, checking whether the amount of stored gas in the air purifier 3 is sufficient or not, and timely inflating and pressurizing by adopting a compressed air pipe when the pressure value is insufficient; before a driver of the roadheader starts the roadheader, a safety helmet and a dustproof mask which are worn are removed, a sand blasting protective helmet 7 is replaced, a pipeline is connected, and the air purifier 3 and the air temperature regulator 6 are firmly fixed on the roadheader; and opening the air inlet valve 4, adjusting the proper air quantity and air temperature, and then starting up to run for operation.
The above-mentioned embodiments are merely to describe the preferred embodiment of the present invention, and are not to limit the scope of the present invention, and those skilled in the art can make various modifications and improvements on the technical solution of the present invention without departing from the spirit of the present invention, and all should fall into the scope of the present invention.
