Description
Technical field
The utility model relates to a kind of slip ring structure, especially a kind of high-protection level slip ring structure that is used for coiling electric motor.
Background technology
All the time, many use electromechanics trade industrial and minerals are more abominable, and as traditional industries such as colliery, mine, cement, general cement industry uses coiling electric motor more.And the slip ring structure of coiling electric motor generally is designed to outer slip ring, and the slip ring degree of protection is generally open type IP23.Under the complicated like that abominable condition of work of cement industrial and mineral, a large amount of dust, cinders are infiltrated slip ring, cause slip ring because of the dust overheap forms short circuit, blows out even burns out easily, have directly influenced the production of this whole production streamline like this.For this reason, cause damp production, enhance productivity if there is a kind of motor sliding ring structure of high-protection level must significantly reduce slip ring hidden danger.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of high-protection level slip ring structure that guarantees motor by the coiling electric motor of full property and reliability is provided.
The technical scheme that provides according to the utility model, the high-protection level slip ring structure of described coiling electric motor, comprise the slip ring chamber, feature is: the slip ring cooler is installed in the upper end in described slip ring chamber, and the air inlet of described slip ring cooler is connected with cooler of electric motor by the air intake curved pipe; Inner chamber in the slip ring chamber is provided with first dividing plate and second partition, and first dividing plate and second partition are separated into the cavity of left part, the cavity at middle part and the cavity of right part with the slip ring chamber; Above the right part cavity, be provided with the air inlet that is communicated with the slip ring cooler, above the cavity of middle part, be provided with air outlet, on first dividing plate and second partition, be provided with ventilation hole; In the cavity of middle part, fan is installed, below the right part cavity, filter is installed.
Middle part at described right part cavity is equipped with slip ring, and brush holder support is installed above slip ring.Described slip ring is installed on the motor shaft of motor.
In described slip ring cooler inside cooling water pipe is installed.
The wall of described slip ring chamber is the structure of sealing.
The utility model is simple, safety, and action effect is obvious; Do not change heating situation under, under the condition that guarantees motor safety and reliability,, reach the degree of protection that increases slip ring by the slip ring structure Design is changed, promoted the bad working environments scope of application of coiling electric motor.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with concrete accompanying drawing.
As shown in the figure: the slip ring structure comprises cooler of electric motor 1, air intake curved pipe 2, cooling water pipe 3, slip ring cooler 4, first dividing plate 5, second partition 6, fan 7, brush holder support 8, slip ring 9, filter 10, motor shaft 11, slip ring chamber 12, motor 13 etc.
The utility model comprises slip ring chamber 12, in the upper end of slip ring chamber 12 slip ring cooler 4 is installed, and the air inlet of described slip ring cooler 4 is connected with cooler of electric motor 1 by air intake curved pipe 2; Inner chamber in slip ring chamber 12 is provided with first dividing plate 5 and second partition 6, the first dividing plates 5 and second partition 6 slip ring chamber 12 is separated into the cavity of left part, the cavity at middle part and the cavity of right part; Above the right part cavity, be provided with the air inlet that is communicated with slip ring cooler 4, above the cavity of middle part, be provided with air outlet, on first dividing plate 5 and second partition 6, be provided with ventilation hole; Fan 7 is installed in the cavity of middle part, filter 10 is installed below the right part cavity, slip ring 9 is installed, brush holder support 8 is installed above slip ring 9 at the middle part of right part cavity;
Described slip ring 9 is installed on the motor shaft 11 of motor 13;
In described slip ring cooler 4 inside cooling water pipe 3 is installed;
The wall of described slip ring chamber 12 is the structure of sealing.
The course of work of the present utility model: at first pass through air intake bend pipe 2 with in the cooling water pipe 3 the part wind introducing slip ring cooler 4, form the outer wind path of slip ring cooler from cooler of electric motor 1.In slip ring chamber 12, increase by first dividing plate 5 and second partition 6,3 chambeies will be divided in the slip ring chamber 12, by the circulation wind path in the centrifugal fan formation slip ring chambers 12 7, the heat that produced in motor operation course of brush holder support 8 and slip ring 9 is brought to the top of end shield with interior circulation wind path like this, outer wind path at the top owing to slip ring cooler 4 carries out heat exchange with it by cooling water pipe 3, it is indoor that the cooling of hot-air in the slip ring is entered slip ring once more, remaining hot blast like this goes out, cold wind advances, and has effectively reduced the indoor temperature rise of slip ring.Simultaneously, for in time getting rid of brush holder support 8 and slip ring 9 because the carbon dust that high speed rotary grinding produces, be provided with filter 10 in the bottom of slip ring chamber, at indoor this one deck screen pack of wind path circulation time process of slip ring, with the carbon dust effective collection, regularly extract out and clean out, effectively guaranteed unsafe factor such as to cause carbon dust to be piled up causing that slip ring is blown out because of the untimely cleaning of carbon dust.
The utility model changes traditional open type slip ring structure, cancelled the shutter of the slip ring chamber wall of former slip ring structure, made full-closed structure, at indoor increase by one dividing plate of slip ring, the slip ring chamber is divided into 3 chambeies, like this by the circulation wind path of centrifugal fan in indoor formation one closure of slip ring.Increase by a little cooler at the slip ring top, inside is covered with pipe, and the cooler by the motor top connects a pipeline and draws a part of wind by the little cooler pipeline in slip ring top, finishes heat exchange with the interior wind path of slip ring, takes away slip ring and causes thermogenetic heat.
