Description
Technical Field
The utility model relates to a device for giving quick material loading of gunning machine of RH vacuum refining furnace belongs to steelmaking equipment technical field.
Background
After the RH vacuum refining furnace is operated for a period of time, the refractory of the dip pipe must be gunned so as to prolong the service life of the dip pipe, reduce the consumption of the dip pipe and keep the continuity of production. If the spray repair is not timely, accidents such as the vacuum tank is off-line in advance, the dip pipe penetrates steel and the like can be caused. The dip pipe refractory generally uses the gunning machine to spout the repair, and the material jar capacity that is used for holding the refractory on the gunning machine is less, and the refractory must in time material loading after using up, nevertheless because material jar internal pressure is higher, need carry out the pressure release to the material jar earlier before opening the charging valve material loading, and some refractory can be followed the air current and followed the charging valve blowout otherwise, cause the waste and the raise dust pollution of resource. Because the existing feeding device has no pressure relief function, the feeding device can only open the feeding valve for feeding after the charging bucket naturally relieves the pressure, has long feeding time, can not meet the requirement of fast-paced steelmaking, and seriously influences the smooth production.
SUMMERY OF THE UTILITY MODEL

The utility model discloses when utilizing pneumatic blow-off valve to open for RH vacuum refining furnace gunning machine's material jar pressure release, the feed inlet that utilizes the reinforced butterfly valve that has established ties pneumatic delay valve to make the material jar delays to be opened, not only can effectively shorten the material loading time of material jar, guarantees that production goes on smoothly, and remaining resistant material can not spout in the material jar moreover to the waste and the raise dust pollution of resource have been avoided.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Fig. 1 is a schematic structural diagram of the present invention.
The reference numbers in the figures are as follows: 1. the device comprises a pneumatic blow-off valve, 2, a feeding hopper, 3, a pneumatic vibrator, 4, a feeding butterfly valve, 5, a charging bucket, 6, a pneumatic delay valve, 7, an air source, 8, a manual ball valve, 9 and an electromagnetic reversing valve.
Detailed Description
The utility model provides a quick loading attachment of RH vacuum refining furnace gunning machine, the device can accomplish the material loading fast and stop gunning refractory (resistant material) blowout, can not cause the raise dust pollution.
Referring to fig. 1, the utility model discloses mainly include pneumatic blow-off valve 1, feeding funnel 2, pneumatic vibrator 3, reinforced butterfly valve 4, pneumatic time delay valve 6, air supply 7, manual ball valve 8 and solenoid directional valve 9.
The air source 7 is connected on the electromagnetic directional valve 9, and the pneumatic blow-off valve 1 is installed in the top of material jar 5, shares an electromagnetic directional valve 9 with DN300 reinforced butterfly valve 4 that installs in the material jar feed inlet, and two routes air sources that electromagnetic directional valve 9 divides are used for controlling opening and closing of DN25 pneumatic blow-off valve 1 and DN300 reinforced butterfly valve 4. One path is a closed air source, and is directly led to the DN25 pneumatic diffusion valve 1 and the DN300 charging butterfly valve 4 respectively after coming out of the electromagnetic directional valve 9 to control the closing of the two valves (the two valves are closed simultaneously after the electromagnetic directional valve 9 gives an instruction). The other path of air source is an opening air source and is divided into two paths after coming out from the electromagnetic directional valve 9, one path of air source is directly led to the DN25 pneumatic bleeding valve 1 and is used for opening the pneumatic bleeding valve 1, the other path of air source is led to the pneumatic delay valve 6 and is led to the DN300 charging butterfly valve 4 through the pneumatic delay valve 6, the opening of the DN300 charging butterfly valve 4 is controlled, the pneumatic bleeding valve 1 is firstly opened after the electromagnetic directional valve 9 gives an instruction, and then the DN300 charging butterfly valve 4 is opened.
The selection of the pneumatic delay valve 6 is determined according to the time for diffusing the air pressure in the charging bucket 5 to be normal atmospheric pressure, and can be adjusted to ensure that the DN300 charging butterfly valve 4 is opened after the diffusion of the charging bucket 5 is finished.
The pneumatic vibrator 3 is arranged on the outer wall of the feeding hopper 2, the power gas is taken from a gas source 7, a manual ball valve 8 is additionally arranged in the middle, and the vibration and the stop of the pneumatic vibrator 3 are manually controlled.
When needs material loading, through the pneumatic diffusion valve 1 of electromagnetic directional valve 9 control DN25 and DN300 reinforced butterfly valve 4, owing to DN300 reinforced butterfly valve 4 control gas circuit middle series connection pneumatic delay valve 6, make this valve delay open, there is not atmospheric pressure in the material jar 5 this moment, and remaining material can not follow the material loading mouth blowout in the material jar 5, has reduced environmental pollution, has guaranteed operating personnel's safety. And in the charging process, the DN20 manual ball valve 8 is opened, and the pneumatic vibrator 3 is started, so that the gunning mix can quickly enter the charging bucket 5.
