Abstract
The utility model relates to a be applied to and pick up stifled grey device is prevented to noise wave pipe of noise in power boiler stove. The method solves the defects that the waveguide tube is often blocked due to too large dust in the boiler furnace when the existing straight cavity waveguide tube is used, and the accuracy of the picked sound wave data is influenced because the straight cavity waveguide tube is easily subjected to direct radiation of heat and a light source at the inlet of the waveguide tube. The waveguide tube of the device is bent and is provided with two parts, namely a short ash-passing tube and a small ash-blowing tube, so that the device has the function of preventing ash blockage. The device has simple structure, low cost and convenient use, and does not need to be shut down for maintenance; the method is suitable for monitoring the operation of boilers of various models.
Description
The utility model relates to a kind of isolated plant that is applied to pick up the boiler of power plant internal noise, particularly relates to a kind of anti-blocking apparatus for ash of noise waves conduit of pick-up noise.
The device of the normal operation of existing supervision boiler of power plant generally is to come the sound wave that picks up in the boiler stove is passed to sensor with the noise waves conduit.Existing waveguide is straight type hollow-pipe waveguide, when straight type hollow-pipe waveguide was used in the boiler of power plant stove noise pickup this, because in-furnace dust dirt is big, dust often stopped up straight type hollow-pipe waveguide is inner, thereby make straight type hollow-pipe waveguide can not correctly conduct noise in the stove, lose effect.Existing straight type hollow-pipe waveguide exists that sensor that easy obstruction is connected with straight type hollow-pipe waveguide one end is subject to the direct radiation of waveguide porch heat, light source and the defective that influences the accuracy of sonic data.
The purpose of this utility model is to provide a kind of anti-blocking apparatus for ash of noise waves conduit that has the anti-clogging function and can improve the sonic data accuracy.
The utility model is realized its purpose by following proposal.The anti-blocking apparatus for ash of a kind of noise waves conduit, it is made up of sensor, heat guard, short tube and valve that order links to each other, it is characterized in that being connected with a curved tube connector at an end of valve, at the crooked outstanding position of tube connector one opening is arranged, opening part is welded with a logical grey short tube that communicates with tube connector, and the tube connector skin also is welded with one and not connectedly with the tube connector runs parallel blows grey tubule.One of logical grey short tube, be rotary with one and be used to the bolt that seals and open, the other end communicates with tube connector.Tube connector is outer field to blow grey tubule internal diameter size between diameter 5mm～diameter 20mm.Curved tube connector afterbody porch can be the garden shape of the mouth as one speaks, also can be the flat shape of the mouth as one speaks.
Advantage of the present utility model is: 1, simple in structure, with low cost; 2, can realize two kinds of ash disposal plugging functions; 3, easy to use, needn't shutdown maintenance; 4, applied widely, the boiler of various models and structure is all applicable; 5, curved tube connector has an angle of bend, can guarantee the direct radiation that sensor that waveguide one end connects does not directly bear waveguide porch heat, light source, makes the sonic data that picks up more accurate.
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing embodiment of the present utility model is done detailed explanation.
With reference to accompanying drawing: sensor 1 is connected on the heat guard 2, and heat guard 2 is connected on the short tube 3.The other end of short tube 3 is connected on the valve 4, the other end of valve 4 is connected on the curved tube connector 5, at curved tube connector 5 crooked outstanding positions one opening is arranged, opening part is welded with a logical grey short tube 7, and 7 one of logical grey short tubes communicate with curved tube connector 5, and there are a bolt 6 embolisms the other end, when bolt 6 is opened, disclose down from logical grey short tube 7 with an iron bar, just can disclose the stifled ash in the curved tube connector 5, very easily remove the stifled ash in the curved tube connector 5.Screw on bolt 6, can work at once, needn't blowing out remove stifled ash in the tube connector.Curved tube connector 5 extexines be welded with one with curved tube connector rear runs parallel blow grey tubule 8, the internal diameter that blows grey tubule 8 is between diameter 5mm～diameter 20mm, and the afterbody gas outlet and curved tube connector 5 afterbodys that blow grey tubule 8 enter the mouth distance between 10mm～400mm.Too closely then influence the sonic data accuracy that curved tube connector 5 afterbodys inlet picks up, too far then can not blow away curved tube connector 5 afterbodys inlet dirt ash on every side.Blow grey tubule 8 and can be connected on the continuous all dusts of porch of curved tube connector 5 tails that purge on the compressed air pump.In order to enlarge the working range that the utility model is suitable for, curved tube connector 5 afterbodys inlet can be made the garden shape of the mouth as one speaks, also can make the flat shape of the mouth as one speaks.
Claims (4)
1, the anti-blocking apparatus for ash of a kind of noise waves conduit, it is made up of sensor, heat guard, short tube and valve, it is characterized in that being connected with a curved tube connector at an end of valve, at the crooked outstanding position of tube connector one opening is arranged, opening part is welded with a logical grey short tube that communicates with tube connector, and the tube connector skin also is welded with one and not connectedly with the tube connector runs parallel blows grey tubule.
2, the anti-blocking apparatus for ash of noise waves conduit according to claim 1 is characterized in that logical one of grey short tube is rotary with one and is used for the bolt that seals and open.
