Description

Air dryer for lorry

Technical field

The utility model relates to truck air technical field of drying, and in particular to the air dryer for lorry.

Background technique

In vehicle compressed air power control system, compressed air is generated using air compressor as high-pressure air source, is made For in the braking system or suspension arrangement of vehicle.It cannot be filtered by general filter device since the compressed air of generation contains The moisture and minute impurities and compressed air fallen is in compression process and the mist of oil liquid by bringing into during transfer pipeline Drop, so that the pneumatic system of vehicle is easy to the impurity being mixed into blocking, minute impurities, oil droplet and moisture in compressed air are not Pneumatic system pipeline is only polluted, and so that the component of system is generated corrosion and goes bad, reduces the service life of pneumatic device, more The serious is, when pneumatic system is under cold conditions in use, the moisture in compressed air can condense in the channel, blocking pipeline It is acted with braking elements, causes system work failure, reduce the reliability of atmospheric control, cause the accident.Therefore, present one As inflate pump output terminal connection air dryer, with to enter automobile pipeline in air carry out moisture absorption.

Setting filter core, chemical drier and oil absorbent material in existing air dryer, compressed gas is by filter core to impurity It is filtered, moisture is absorbed by chemical drier, oil absorbent material mainly adsorbs the grease in compressed air.But Be that existing air dryer has the following problems: 1, existing oil absorbent material can not only absorb grease, and can absorb compressed air In moisture, need the later period to separate grease, increase the later period recycling grease difficulty；2, existing oil recovery passes through oil The discharge of rouge self gravity, recovery efficiency are lower.

Utility model content

The utility model be intended to provide be used for lorry air dryer, only grease is adsorbed, and recovery efficiency compared with It is high.

In order to achieve the above objectives, the utility model adopts the following technical solution: for the air dryer of lorry, including it is dry Dry cylinder, the lower part of drying cylinder are connected with air inlet pipe, and the top of drying cylinder is connected with escape pipe, is equipped with horizontal baffle in drying cylinder, The both ends of horizontal baffle are slidably connected with the inner wall of drying cylinder respectively, and drying cylinder inner wall, which is located at below horizontal baffle, to be fixedly connected with The lower end surface of limited block, horizontal baffle is equipped with oil recovery mechanism；Drying cylinder is divided into epicoele and cavity of resorption by horizontal baffle, it is horizontal every Plate lower end surface is connected with snorkel, and snorkel is equipped with the first breather cheek valve, it is upper it is intracavitary be placed with multiple expanded graphite tablettings, Under it is intracavitary be provided with desiccant, be fixedly connected with extension rod on horizontal baffle, drying cylinder is stretched out in the end of extension rod, drying cylinder Outside is fixedly connected with the first cylinder, and the piston rod of the first cylinder is fixedly connected with extension rod, and the outside of drying cylinder is equipped with temporary Case, holding tank are connected to by the first tracheae with air inlet pipe, and holding tank is connected to by the second tracheae with the first cylinder, on the first tracheae First control valve is installed, the second control valve is installed on the second tracheae.

The utility model has the advantages that

1, in the upper intracavitary multiple expanded graphite tablettings of setting in the utility model, expanded graphite tabletting has loose porous knot Structure has powerful adsorption capacity to grease, is effectively adsorbed to the grease in compressed air, meanwhile, expanded graphite tabletting Grease is only adsorbed, the later period without carrying out water-oil separating, reduces Grease Collection difficulty.

2, it is collected using holding tank to air is partially compressed in the utility model, when the dry completion of deoiling of compressed air Afterwards, control valve is opened, by the compressed air in holding tank as power source, compressed air pushes first in the first cylinder to live Stopper rod movement, and then horizontal baffle is pushed to move to escape pipe direction, upper intracavitary multiple expanded graphite tablettings are squeezed, So that the grease discharge of expanded graphite tabletting absorption, and recycled by collecting box.It, can by way of this extruding oil extraction Quickly to recycle to grease, and using the high pressure characteristics of compressed air, the oil extraction effect of expanded graphite tabletting is more preferable.

Further, oil recovery mechanism includes collecting box, hard tube and hose, and collecting box is located at the outside of drying cylinder, is collected Case is connected to by hard tube with the outer wall of drying cylinder, and hard tube is connected to by hose with the lower end surface of horizontal baffle.

By the way that above structure is arranged, the grease of expanded graphite tabletting absorption is quickly recycled, collecting box is placed on On the outside of drying cylinder, convenient for the grease in collecting box to be used for the other actuating units of lorry, the later period installs and using more convenient.Together When, since horizontal baffle can move up and down under the action of the first cylinder, hose moves in desiccant, stirs desiccant It is dynamic, convenient for accelerating the discharge of the moisture in desiccant, so that desiccant is reused.

Further, escape pipe includes first segment, second segment and third section, and first segment is connect with third section by second segment, First segment and third section are vertically arranged, and second segment is arranged diagonally downward, and third section is connected to the top of drying cylinder.Escape pipe is set Structure, when extrusion expansion graphite tabletting, increase the difficulty that grease is overflowed from escape pipe.

Further, the junction of second segment and third section is horizontally disposed first baffle, and first baffle is interior with third section Wall has a gap, and the junction of first segment and second segment is horizontally disposed a second baffle, between the inner wall of second baffle and first segment has Gap.By setting first baffle and second baffle, when extrusion expansion graphite tabletting, the difficulty that grease is overflowed from escape pipe is increased Degree.

Further, hard tube is arranged diagonally downward to collecting box direction, and the grease convenient for squeezing out flows in collecting box.
