Abstract
The utility model relates to a kind of nuclear power station feed pump inlet filter filter core attaching/detaching apparatus, the dismantling device includes bracket and crowbar, the filter core is fixed on bracket, the bracket is equipped with fulcrum, the crowbar agitates filter core bottom by fulcrum, to adjust the concentricity of filter core and filter cylinder.Compared with prior art, the utility model is reasonable with dismounting process, protects part of appliance, simple operation and other advantages.
Description
Technical field
The utility model relates to Y-tubes formula art of filters, more particularly, to a kind of nuclear power station feed pump ingress filtering
Device filter core attaching/detaching apparatus.
Background technique
Domestic Secondary Circuit of PWR main feed system entrance of water-supplying pump filter generallys use the filtering of Y-tubes formula
Device, effect is impurity in filter medium, protects upstream device.This kind of filter is small with flow resistance, blowdown is convenient, structure
The features such as simple, difference can be divided into vertical and two kinds horizontal according to the installation method.When using vertical installation, filter element end cap is opened
Mouth obliquely, as shown in Figure 1, using chain block as auxiliary when the dismounting filter core of scene, carries out disassembling operations by manpower, tears open
It is had the following problems during dress:
1, since filter core quality is big, volume is big, when dismounting, is influenced by vertical direction gravity, cannot keep filter core and filter
The concentricity of cylinder forces push-and-pull filter core to may cause wall friction in filter core lower part and filter cylinder, damages filter core.
It 2, can not be by chain block in the initial stage of dismounting and the final stage of time dress by site examining and repairing space constraints
It is drawn off or is returned dress, manpower can only be relied on, misoperation may occur personnel and injure or squeeze wound by a crashing object.
Utility model content
The purpose of this utility model be exactly in order to overcome the problems of the above-mentioned prior art and provide a kind of nuclear power station to
Pump entrance filter core disassembling device.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of nuclear power station feed pump inlet filter filter core attaching/detaching apparatus, the dismantling device include bracket and crowbar,
The filter core is fixed on bracket, and the bracket is equipped with fulcrum, and the crowbar agitates filter core bottom by fulcrum, is come
Adjust the concentricity of filter core and filter cylinder.
Preferably, the bracket is rectangular plate.
Preferably, the bracket both ends are respectively provided with a long hole, for fixing filter core and bracket.
Preferably, the bracket middle position is equipped with a circular hole, and the circular hole is as the fulcrum, the crowbar
It is abutted after circular hole with filter core bottom.
Preferably, the long side of the plate is equipped with vertical flanging.
Preferably, the bracket is the bracket being made using No. 10 channel steel materials of standard.
Preferably, the length of the bracket is identical as filter end cap outer diameter.
Preferably, the crowbar is seamless steel pipe.
Preferably, the dimension of the crowbar is less than 25mm, and length is 1.5 times of filter core length.
Preferably, the crowbar and filter core contact face are equipped with arc angling.
Compared with prior art, the utility model has the advantage that
1, dismounting process is reasonable, protects part of appliance.Filter core and filter cylinder concentricity are adjusted by crowbar when dismounting,
Alleviate filter core and cylinder friction, avoids damage filter core；
2, easy to operate, reduce personnel's operating risk.Personnel are avoided directly to connect with filter core, cylinder by operating this tool
Touching, the personnel of being effectively reduced injure by a crashing object, squeeze cold danger.
Detailed description of the invention
Fig. 1 is that the filter core of the utility model dismounts schematic diagram；
Fig. 2 is the supporting structure schematic diagram of the utility model；
Fig. 3 is the bracket side view of the utility model.
Wherein 1 is filter core, and 2 be filter cylinder, and 3 be crowbar, and 4 be bracket, and 41 be long hole, and 42 be circular hole, and 43 be flanging.
Specific embodiment
The technical scheme in the embodiment of the utility model will be carried out clear, be fully described by, it is clear that described below
Embodiment is a part of the embodiment of the utility model, rather than whole embodiments.Based on the embodiments of the present invention, originally
Field those of ordinary skill every other embodiment obtained without making creative work all should belong to this
The range of utility model protection.
As shown in Figure 1, a kind of nuclear power station feed pump inlet filter filter core attaching/detaching apparatus, for cooperating chain block to incite somebody to action
The filter core of filter dismounts, and the dismantling device includes bracket 4 and crowbar 3, and the filter core 1 is fixed on bracket 4, described
Bracket 4 is equipped with fulcrum, and the crowbar 3 by fulcrum agitates 1 bottom of filter core to adjust the same of filter core 1 and filter cylinder 2
Axis degree.
As shown in Figures 2 and 3, the bracket 4 is rectangular plate.4 both ends of bracket are respectively provided with a long hole
41, for fixing filter core 1 and bracket 4.The size of the long hole 41 is 30 × 100mm of φ, more secured with the fixation of filter core.
4 middle position of bracket is equipped with a circular hole 42, which wears as the fulcrum, the crowbar
It is abutted after crossing circular hole with filter core bottom.The circular hole 42 is having a size of φ 50mm.
The long side of the plate is equipped with vertical flanging 43, further improves the operation ease of bracket.
The bracket 4 is the bracket being made using No. 10 channel steel materials of standard.The length and mistake of the bracket 4
