Abstract
The utility model relates to a double air filtering structure of an engine of a rotary drilling rig. The structure comprises a T-type hose clamp, an elbow, a manifold, air filters, a hose clamp, a hose, a left joint, pre-filters, a front joint, a front hoop, a left elbow, a left hoop and a front elbow, wherein the two air filters are arranged on the left and front sides of the engine, parallelly connected to an air inlet of a turbocharger of the engine through the T-type hose clamp, the elbow, the manifold, the left elbow and the front elbow, and fixedly arranged on a hood through the front hoop and the left hoop; and the two pre-filters are connected with the two air filters through the hose clamp, the hose, the left joint and the front joint, and fixedly arranged on a hood through flanges of the left joint and the front joint. The double air filtering structure has the advantages that the matching problem of the air filters with the pre-filters of the engine with a large discharge capacity used in a large-scale rotary drilling rig and the arranging problem of the whole machine are effectively solved, and small-scale standard air filters and pre-filters are adopted to replace large-scale specially-made air filters and pre-filters, so that the production and utilization cost can be greatly reduced.
Description
Technical field
The utility model relates to a kind of rotary drilling rig, relates in particular to the two empty filter structures of a kind of rotary drilling rig motor.
Background technique
The rotary drilling rig bigger site construction of dust of being everlasting in order to prolong empty filter filter core working life, reduces customer using cost; The rotary drilling rig motor need be installed empty filter; It can the airborne hard dust granule of filtering, to motor clean air is provided, and prevents that dust from causing engine scuffing.The structure of air-strainer and capacity must satisfy the usability and the operating conditions of motor.General air-strainer fair big more with flow, then the filter area of its boundary dimension and filter core is big more, and the corresponding capacity that holds dust is also big more.In order to satisfy the large-duty engine performance requirement that large type drill uses, need the design coupling to have the sky filter of big air mass flow.
Summary of the invention
The utility model technical problem to be solved is: provide a kind of rotary drilling rig motor two empty filter structures; Solve the empty filter of large-duty engine of rotary drilling rig use and the coupling and the whole machine installation difficult arrangement problem of prefilter, reduce simultaneously and make and user cost.
The utility model is that the technological scheme that problem adopted of the above-mentioned proposition of solution is:
The two empty filter structures of a kind of rotary drilling rig motor; Comprise T type larynx hoop 1, bend pipe 2, manifold 3, empty filter 4, larynx hoop 5, flexible pipe 6, left joint 7, prefilter 8, front connector 9, preceding anchor ear 10, left bend pipe 11, left anchor ear 12, preceding bend pipe 13; Two empty filters 4 are arranged in motor left side and front end; Be connected in parallel in engine turbine pressurized machine suction port through T type larynx hoop 1, bend pipe 2, manifold 3, left bend pipe 11 and preceding bend pipe 13, two empty filters 4 are fixedly installed on the hood with left anchor ear 12 through preceding anchor ear 10;
Two prefilters 8 are connected with two empty filters 4 through larynx hoop 5, flexible pipe 6, left joint 7, front connector 9, and are fixedly installed on the hood through the flange plate of left joint 7 and front connector 9.
The beneficial effect of the utility model is: can be good at solving the empty filter of large-duty engine of large-scale rotary drilling rig use and the coupling and the whole machine installation difficult arrangement problem of prefilter.Adopt small-sized standard null filter and prefilter to replace large-scale special empty filter and prefilter, can reduce greatly and make and user cost.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the plan view of Fig. 1.
Wherein, 1-T type larynx hoop, 2-bend pipe, 3-manifold, the empty filter of 4-, 5-larynx hoop, 6-flexible pipe, 7-left side joint, 8-prefilter, 9-front connector, anchor ear before the 10-, 11-left side bend pipe, 12-left side anchor ear, bend pipe before the 13-.
Embodiment
Further specify the embodiment of the utility model below in conjunction with accompanying drawing.
With reference to Fig. 1; The two empty filter structures of the described a kind of rotary drilling rig motor of this embodiment; Comprise T type larynx hoop 1, bend pipe 2, manifold 3, empty filter 4, larynx hoop 5, flexible pipe 6, left joint 7, prefilter 8, front connector 9, preceding anchor ear 10, left bend pipe 11, left anchor ear 12, preceding bend pipe 13; Two empty filters 4 are arranged in motor left side and front end; Be connected in parallel in engine turbine pressurized machine suction port through T type larynx hoop 1, bend pipe 2, manifold 3, left bend pipe 11 and preceding bend pipe 13, two empty filters 4 are fixedly installed on the hood with left anchor ear 12 through preceding anchor ear 10;
Two prefilters 8 are connected with two empty filters 4 through larynx hoop 5, flexible pipe 6, left joint 7, front connector 9, and are fixedly installed on the hood through the flange plate of left joint 7 and front connector 9.
The beneficial effect of this embodiment is: can be good at solving the empty filter of large-duty engine of large-scale rotary drilling rig use and the coupling and the whole machine installation difficult arrangement problem of prefilter.Adopt small-sized standard null filter and prefilter to replace large-scale special empty filter and prefilter, can reduce greatly and make and user cost.
