Abstract

The utility model discloses a nitrogen purging device for a feed valve. The nitrogen purging device consists of an inlet valve, an inlet straight tube section, a fixed support, and an inlet circular arc tube section; wherein two ends of the inlet circular arc tube section are provided with openings connected with inlet/outlet gas, a plurality of purging holes are provided within a certain angle; the inlet straight tube section passes through a feed valve wall and is connected to a nitrogen gas source; and the fixed support is welded near a feed short tube opening inside the feed valve. When the feed valve operates, purging is performed for an inner part of the feed valve and a sealing gasket, the nitrogen can realize the purging for the inner part of the feed valve and the sealing gasket through the inlet valve and the inlet tube purging holes. Compared with the prior art, the nitrogen purging device of the utility model solves the problems that ash deposition of the present feed valve can not be cleaned on line, and the feed valve has the disadvantages of easy damage and short service life.

Description

The inlet valve nitrogen purging device
Technical field
The utility model belongs to the smelter technical field, and is a kind of specifically to preventing the blow device of inlet valve dust stratification.
Background technology
Dedusting ash in the casing is controlled through the switch of inlet valve and is got into the storehouse pump; Inlet valve average every 15-20 divide the charging switch once; Act frequently, along with the frequent switch of inlet valve, the interior dust stratification of the valve particularly dust stratification of sealing gasket causes the inlet valve leakage can't normally fail ash; The inlet valve life-span, on average about one month, frequent maintenance increased equipment maintenance cost and labour intensity.
Summary of the invention
The objective of the invention is can't onlinely to clean in order to solve present inlet valve dust stratification, the problem fragile, that service life is low provides a kind of inlet valve nitrogen purging device.
For achieving the above object, the technical scheme that the utility model adopted is following:
A kind of inlet valve nitrogen purging device comprises being positioned at outer air inlet pipe of inlet valve and the scavenging conduit that communicates with air inlet pipe that is positioned at inlet valve that said scavenging conduit is provided with the purge hole towards inlet valve.
Above-mentioned blow device:
Described scavenging conduit is corresponding circular-arc with inlet valve;
Said air inlet pipe is provided with air intake valve outward;
Described purge hole direction is towards inlet valve and outwards be 45 °;
Described circular-arc scavenging conduit both ends open is evenly distributed with five purge holes on it;
Be provided with fixed support in the said inlet valve, scavenging conduit is fixed on this fixed support.
The operation principle and the beneficial effect of the utility model show:
The utility model is provided with scavenging conduit in inlet valve, scavenging conduit is provided with purge hole, carries gas through placing the outer air inlet pipe of inlet valve, and gas purges inlet valve behind purge hole, thereby plays the effect that prevents the inner dust stratification of inlet valve.
It is corresponding circular-arc with inlet valve that scavenging conduit is, and can well purge inlet valve, purges effective.
The utility model utilizes nitrogen that inlet valve inside and sealing gasket are purged deashing according to the gas purging principle, prevents in the valve and the dust stratification of sealing gasket.The nitrogen purging device of use realized the inner and sealing gasket of inlet valve online ash removal, prolonged service life, reduced the inlet valve fault rate, alleviated labour intensity.Used this blow device inlet valve to extend to three months by original one month equal service life, effect is remarkable.
Description of drawings
Fig. 1 is the structural representation of nitrogen purging device
Among the figure, 1, air intake valve, 2, the air inlet straight length, 3, fixed support, 4, air inlet circular arc pipeline section.
The specific embodiment
Come the invention is described in detail with the specific embodiment below:
As shown in Figure 1, a kind of inlet valve nitrogen purging device, this device is made up of air intake valve 1, air inlet straight length 2, fixed support 3, air inlet circular arc pipeline section 4.
Air inlet pipe adopts seamless pipe to be made, and air inlet circular arc pipeline section 4 both ends opens connect turnover gas, in certain angle, establish a plurality of purge holes, and straight length 2 passes the inlet valve wall and is connected on outward on the nitrogen source of the gas.The switch of valve 1 control nitrogen.Fixed support 3 is welded near the inner charging short tube mouth of inlet valve.When inlet valve moves, inlet valve inside and sealing gasket are purged, nitrogen is realized the purging to inlet valve inside and sealing gasket through valve 1, air inlet pipe purge hole.

Claims (6)

1. an inlet valve nitrogen purging device is characterized in that, comprises being positioned at outer air inlet pipe of inlet valve and the scavenging conduit that communicates with air inlet pipe that is positioned at inlet valve, and said scavenging conduit is provided with the purge hole towards inlet valve.
