Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, the utility model is described in further detail below in conjunction with accompanying drawing.
The utility model is a kind of dust control by ventilation screen pack that is used for frequency converter, this screen pack is by the afterframe that directly is welded on the cabinet door, directly be positioned over the filter core frame in the afterframe groove, and be inserted in the location shrinkage pool of afterframe and fix on the cabinet door, three parts of preceding shrouding of being positioned at the filter core front side form.Introduce this three parts below respectively.
Referring to Fig. 1, filter core frame of the present utility model includes: narrow limit metal framework 2, embedding clamping fix on filter cores 1 in this metal framework 2, that adopt fire proofing to make, and are positioned at filter core one side, are and intersect the trapezoidal wire rack 3 of superimposed shape.This wire rack 3 is to be connected in one by the centre welding by two trapezoidal wire supports, four jiaos of four jiaos of being fastened on filter core metal framework 2 respectively of this wire rack 3, and be installed in the side of filter core 1 towards air inlet.The design of these parts considers it is that air inlet with the filter core frame directly is placed on cabinet comes filtered air, and dirt and dust are stopped outside cabinet.And, fix the filter core 1 that filters ventilation with wire rack 3, cancelling loaded down with trivial details screw installs, utilize steel wire elasticity to guarantee repeatedly to dismantle and modification not, and dismantle very convenient, do not need any instrument just can dismantle when the user safeguards at the scene, and can directly take out cleaning dust and oil stain as the filter core 1 that filters ventilating layer; In place with good conditionsi, can directly use washing machine to clean, thereby alleviate field personnel's workload greatly.
Referring to Fig. 2, afterframe 4 is to be provided with to be used for the box-like hardware that build-in is placed the groove of filter core frame, bottom portion of groove is provided with densely covered numerous ventilation holes 41, be respectively equipped with a plurality of welding procedure through holes 43 on the outwardly directed nib 42 in the groove left and right sides, by these through holes this afterframe 4 directly is welded on frequency converter cabinet door 6 inboards, can either guarantee the installation site like this, also can strengthen the intensity of cabinet door.Afterframe 4 is welded after on the cabinet door, and thereon, all form long narrow shape through hole between two ends side and the cabinet door 6 down, these two long narrow shape through holes are used to fix front baffle.Especially the chimb 52 of shrouding 5 downsides before descending side through hole 44 to be used to be fixed.
Referring to Fig. 3, preceding shrouding 5 is middle metal plates that slightly are outstanding and are provided with densely covered numerous ventilation holes 51, and its downside is provided with a long narrow shape chimb 52, is respectively equipped with the long narrow shape nib 53 as handgrip in the both sides up and down of its front panel.The nib two ends that location notch through hole between afterframe 4 and the cabinet door 6 is stretched out in the upper end of preceding shrouding 5 are respectively equipped with manhole 54.The design criterion of this part is simple in structure, practical, and on-the-spot installation easily, conveniently.It all has only than small size with afterframe 4 and contacting of filter core 1, and avoiding the installation difficulty after the steel plate modification that large tracts of land contact brings, and the both sides up and down of plate are provided with two dismounting handles 53 up and down respectively in front, with for convenience detach.When the steel plate modification of cabinet door or other part is severe, can utilize two circular holes 54 on top and instrument to dismantle, shrouding 5 is torn the situation of not getting off open before avoiding taking place.
Referring to Fig. 4, introduce the utility model and be installed in situation on the cabinet door, in whole erection, earlier afterframe 4 is welded on cabinet door 6 inboard air inlet places, again the filter core frame is placed on the groove the inside of afterframe 4, then preceding shrouding 5 upper end nibs being installed in the long narrow shape of reserving on the afterframe 4 earlier installs in the through hole, utilize gravity principle again, the long narrow shape chimb 52 in shrouding 5 lower ends falls into the installation through hole 44 of afterframe 4 downsides automatically before making, by the elasticity of the wire rack 3 inside the filter core frame, in the air-supply process, can not send sound.The mode of this installation and regular maintenance is very simple, just can realize without any need for instrument, can also the dustproof performance of ventilating of fine solution.
The utility model is manufactured experimently out the embodiment model machine, and has carried out running experiment, and result of the test is successful, has realized goal of the invention.
