Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the enlarged drawing at A place in Fig. 1.
In figure: main casing 1, upper shell cover 11, lower house 12, capping plate 121, circuit chamber 1a, inlet chamber 1b, shell air inlet 1c, shell steam vent 1d, vertical clapboard 2, airway 3, impeller inducer 31, whirlwind cone cylinder 4, tangential admission pipe 41, filtering net cylinder 42, interior ash cylinder 43, bottom 44.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is further described.
nullSuch as Fig. 1、In embodiment shown in Fig. 2，A kind of elevator frequency converter shell structure，Including main casing 1，Main casing includes upper shell cover 11、The lower house 12 of upper end open，Upper shell cover seal lower house upper end open and and lower house between removably connect，Vertical clapboard 2 it is provided with in described main casing、Airway 3，Vertical clapboard will be separated into circuit chamber 1a inside main casing、Inlet chamber 1b，Lower house is provided with shell air inlet 1c，Main casing is provided with at least one shell steam vent 1d connected with circuit chamber，It is provided with in inlet chamber in round table-like whirlwind cone cylinder 4，In whirlwind cone cylinder、The equal opening in lower end and upper end open are more than lower ending opening，Whirlwind cone cylinder is provided with for the tangential admission pipe 41 of tangential admission in whirlwind cone cylinder，Tangential admission pipe one end connection whirlwind cone cylinder，Tangential admission pipe other end connection shell air inlet，Airway end is at circuit intracavity，The airway other end connects through vertical clapboard and with inlet chamber inside，One end that airway is in inlet chamber is docked with whirlwind cone cylinder upper end open，It is provided with in airway by the impeller inducer 31 of driven by motor，The wind-guiding direction of impeller inducer is by airway to circuit chamber.Being provided with filtering net cylinder 42 in described whirlwind cone cylinder, filtering net cylinder is spaced apart with whirlwind cone cylinder upper end open by tangential admission pipe, and filtering net cylinder is provided with multiple filtering holes.Circuit chamber is used for fixing various electric circuit electronics technical element is installed.
Extraneous air inevitably has dust impurity, under the effect of impeller inducer, extraneous air is by shell air inlet, tangential admission pipe, by tangential or approximate tangential in the way of enter in whirlwind cone cylinder, and in whirlwind cone cylinder, form eddy flow, the dust impurity of relatively heavy (bigger) is adherent, subsequently owing to gravity falls gradually, air draught is then entered in dirt cup (if without filtering net cylinder structure by each filtering holes, then air draught can from middle part back pressure, reach up to the logical upper end open of whirlwind cone), and reach up to the logical upper end open of whirlwind cone, with after reach circuit intracavity through airway, the electric circuit electronics technical element of circuit intracavity is carried out cooling heat radiation, and it is final from the discharge of shell steam vent.Consequently, it is possible to utilize impeller inducer can carry out powerful effective wind guide and heat dispersion, and radiating airflow is purified by physical property, it is possible to greatly reduce the dust stratification of electric circuit electronics technical element, it is prevented that the heat-sinking capability that dust stratification too much causes is poor.
The base plate of described lower house includes base plate body, capping plate 121, and base plate body is provided with the shrouding hole corresponding with covering plate, capping plate be in shrouding hole and and base plate body between clamping, capping plate seals whirlwind cone cylinder lower ending opening completely.After work a period of time, it is not necessary to carry out the dismounting of internal structure, directly take off capping plate and achieve that the toppling over of dust impurity, clear up.
The interior ash cylinder 43 of an equal opening of upper and lower end it is provided with in described whirlwind cone cylinder, filtering net cylinder lower end is provided with ash port, interior ash cylinder upper end open is docked with ash port, and interior ash cylinder lower end is provided with the bottom 44 for sealing interior ash cylinder lower ending opening, threadeds between bottom with interior ash cylinder lower ending opening.Being equivalent to big ash silo outside interior ash cylinder, the inside is usually " cinder " (bulky grain dust impurity), is then " fine ash " (little particle dust impurity) inside interior ash cylinder.When needing to carry out the toppling over of interior ash cylinder internal dust impurity, clearing up, it is possible to directly screw off bottom and process, convenient and swift.And " cinder ", " fine ash " are separately, be conducive to reclaiming and post processing.
