Abstract
The utility model discloses a take deposition to clean hot-blast isolation of function, including floodgate and slide rail, floodgate slidable mounting is on the slide rail, take deposition to clean hot-blast isolation of function still includes trachea and jet-propelled pipe, trachea end and air supply intercommunication, trachea end and jet-propelled pipe intercommunication in addition, and the jet-propelled pipe passes through trachea fixed mounting and is close to slide rail department at floodgate lateral part, and the jet-propelled pipe is equipped with rectangular shape opening and both ends confined pipeline for following length direction, and rectangular shape opening is towards the slide rail to hot-blast isolation easy deposition takes place the problem of jam among the solution prior art.
Description
Technical Field
The utility model relates to an electric power generation field especially relates to take deposition to clean hot-blast isolation of function.
Background
When the thermal power station unit normally operates, times of wind is heated by the air preheater, times of wind can carry sticky dust on a heat storage element of the air preheater, when times of wind operates to a position 0 of double-plugboard pneumatic hot air isolation, the wind pressure of hot times of wind is 6.40kPa, the wind pressure of cold times of wind is 6.60kPa, the design requirement that the pressure difference between sealing air and hot wind is larger than or equal to 2kPa is not met, the sealing wind cannot isolate hot times of wind, times of wind flows into a side shell of a double-plugboard pneumatic hot air isolation 1 execution mechanism, dust carried by hot times of wind is accumulated, and when the double-plugboard pneumatic hot air isolation is opened, the dust accumulated on a sliding rail blocks normal operation of the plugboard, so that the defect that the wind cannot be opened.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem of providing hot air isolation with the dust-collecting cleaning function so as to solve the problem that the dust is easily collected and jammed by the hot air isolation in the prior art.
take the deposition to clean hot-blast isolation of function, including floodgate and slide rail, floodgate slidable mounting is on the slide rail, take the deposition to clean hot-blast isolation of function still includes trachea and jet-propelled pipe, trachea end and air supply intercommunication, trachea end and jet-propelled pipe intercommunication in addition, and the jet-propelled pipe passes through trachea fixed mounting and is close to slide rail department at floodgate lateral part, and the jet-propelled pipe is for being equipped with rectangular shape opening and both ends confined pipeline along length direction, rectangular shape opening towards the slide rail.
The air ejector pipe is also provided with a nozzle, the nozzle is a flat air pipe, the opening at the end of the nozzle is matched with the long strip-shaped opening on the air ejector pipe and is communicated with the air ejector pipe, and the opening at the other end of the nozzle points to the sliding rail.
The utility model has the advantages that:
compared with the prior art, this practicality is close to slide rail department and sets up the jet-propelled pipe at floodgate lateral part for slide rail department laying dust is cleaned, has avoided taking the laying dust to clean the hot-blast isolation jam of function, this simple and practical, the jam problem of being particularly suitable for solving hot-blast isolation slide rail laying dust.
Drawings
Fig. 1 is a front view of the present invention;
fig. 2 is a cross-sectional view of the left middle section of the present invention;
in the figure, 1 is a fixed wall, 2 is a slide rail, 3 is an air injection pipe, 4 is a gate , 5 is an air pipe, 6 is a long-strip-shaped opening, and 7 is a nozzle.
Detailed Description
The utility model proceeds to step with reference to the accompanying drawings and the specific embodiments:
referring to fig. 1 and 2, area deposition cleans hot-blast isolation of function, including floodgate 4 and slide rail 2, floodgate 4 slidable mounting is on slide rail 2, area deposition cleans hot-blast isolation of function and still includes trachea 5 and jet-propelled pipe 3, trachea 5 end and air supply intercommunication, trachea 5 other end and jet-propelled pipe 3 intercommunication, jet-propelled pipe 3 is close to slide rail 2 department through trachea 5 fixed mounting in floodgate 4 lateral part, jet-propelled pipe 3 is for being equipped with rectangular shape opening 6 and both ends confined pipeline along length direction, rectangular shape opening 6 is towards slide rail 2 during the use, the compressed air of air supply passes through trachea 5 and carries jet-propelled pipe 3, compressed air spouts and blows off the dust on the slide rail 2 from rectangular shape opening 6 on jet-propelled pipe 3 to avoid the dust to block hot-blast isolation .
The air injection pipe 3 is further provided with a nozzle 7, the nozzle 7 is a flat air pipe, an opening at the end of the nozzle 7 is matched with the long strip-shaped opening 6 on the air injection pipe 3 and is communicated with the air injection pipe 3, an opening at the other end of the nozzle 7 points to the sliding rail 2, the air pressure at the sliding rail 2 is increased by the nozzle 7, and the dust removal efficiency is improved.
It will be apparent to those skilled in the art that a number of simple inferences or substitutions can be made without departing from the spirit and scope of the invention and these should be construed as within the scope of the invention.
