Description
Technical field
The utility model relates to nitrogen filtering technical field more particularly to a kind of nitrogen filtering casees for exchanger.
Background technique
In the production of high-voltage isulation cable, usually use nitrogen as protection gas.In actual operation, nitrogen first passes through friendship
Parallel operation could be used for the production of high-voltage isulation cable.When nitrogen passes through exchanger, the impurity in nitrogen is often deposited in exchange
In device, making exchanger that blocking occur reduces exchanger working efficiency or even can not work normally, it is therefore desirable to often dismantle cleaning
Exchanger.The dismantling of exchanger re-assemblies needs and takes a substantial amount of time and labour, makes production disruption, influences production effect
Rate.
Summary of the invention
In order to solve the above-mentioned prior art problems, the utility model provides a kind of nitrogen filtering case for exchanger,
Cabinet including cuboid, wherein one side is connected with air inlet pipe to the cabinet, and the opposite face of the side is connected with escape pipe,
It is equipped with sewage pipe at the tank floor center, further includes several and bottom surface and the vertically disposed strainer of air inlet pipe；Strainer
It is slidably connected in cabinet by the groove on body side inner wall, strainer upper end stretches out cabinet and is equipped with knob；Box top
It is equipped with several and is used for the first long hole that strainer passes through；First long hole and strainer junction are equipped with sealing ring；The cabinet top
Several are equipped at the inner wall of face and the one-to-one fixed plate of strainer, fixed plate are located at the side of strainer, are arranged in parallel with strainer,
Fixed plate is connected with sealing plate by spring relative to the surface of strainer, and the sealing plate is vertical with fixed plate；Sealing plate side
Face connecting spring, other three sides are in contact with cabinet two opposite side inner walls, strainers respectively；Table on the sealing plate
Face is connected with slide bar；The slide bar is vertical with sealing plate and stretches out box top；The box top is equipped with and passes through for slide bar
The second long hole, the length direction of second long hole is vertical with strainer；Strainer is equipped with baffle far from the side of fixed plate, described
Baffle is parallel with fixed plate and is fixed on box top inner wall.
Preferably, low, taper that surrounding is high centered on the tank floor.
It preferably, further include cleaning device；The cleaning device includes water inlet pipe, inlet valve, cleaning sprayer；The water inlet
Pipe is equipped with inlet valve, and the water inlet pipe connects multiple cleaning sprayers；The cleaning sprayer is set to the connection of escape pipe on cabinet
At side inner walls.
Preferably, the cleaning device further includes pressure difference transmitter, and the pressure difference transmitter both ends are connected to cabinet
At interior air inlet pipe and at escape pipe；The signal output end of the pressure difference transmitter is connected with control circuit, the output of control circuit
Connect inlet valve.
The working principle of the utility model are as follows: when needing replacing strainer, will be needed replacing by the knob of strainer upper end
Strainer pulls out Rose Box.After seine pulls out, sealing plate moves at baffle under the action of the spring, so that below the first long hole
Space is sealed, and nitrogen leakage is avoided to cause waste of material.New strainer is placed at the first long hole, pulls slide bar along the
Two long holes are slided to the direction far from strainer, will be in new strainer insertion filtering box body.During replacing strainer, due to
Provided with sealing plate, nitrogen will not leak outside, therefore not need to interrupt the work of exchanger.In addition, more due to the utility model
A strainer is independent of each other when working, so the process of replacement strainer has no effect on the filtering of nitrogen.The utility model can also be real
The function of existing on-line auto-cleaning.The pressure difference signal that pressure difference transmitter will test is input to control circuit, sets when pressure difference reaches
When fixed pressure difference maximum value, control circuit output signal opens inlet valve, and cleaning sprayer cleans strainer.After cleaning
Rose Box is discharged by sewage pipe in impurity in sewage and nitrogen.When the pressure difference signal that pressure difference transmitter detects is reduced to setting
Pressure difference minimum value when, control circuit output signal closes inlet valve, and filter gauze cleaning terminates, and whole process does not need manually to grasp
Make.
Nitrogen filters out impurity by first passing through Rose Box before exchanger in the utility model, and impurity is avoided to enter exchange
Device causes exchanger to block.On-line cleaning and replacement strainer may be implemented in Rose Box in the utility model, does not influence exchanger
Normal work, improve work efficiency, avoid the start-stop bring economic loss of exchanger.
