Abstract
The utility model relates to a central steam stand column fixing structure of a mixing bunker, which comprises a cross beam, a central steam stand column and a steam source inlet pipeline, wherein the central steam stand column is connected and fixed with the cross beam in a plug-in manner, and the upper opening of the side wall of the central steam stand column is detachably and fixedly connected with the steam source inlet pipeline; this fixed knot structure has effectively reduced because of the probability that central steam stand drops and leads to the production to be interrupted, the mediation and the change of the pipeline of being convenient for simultaneously.
Description
Technical Field
The utility model belongs to the technical field of steel smelting equipment technique and specifically relates to a mixing bunker central steam stand fixed knot constructs.
Background
In a sintering workshop of an iron mill, the steam preheating device of the mixing bin of the sintering machine can effectively improve the temperature of mixed materials, improve the yield of sintered ores and reduce the consumption of solid fuels. At present, because the steam preheating central stand column adopts a fixed structure in welded connection, the welding point is extremely easy to corrode and wear, so that the central stand column falls off, the cloth cylinder is blocked to interrupt production, the treatment at each time takes about 3 hours on average, and in order to solve the problem, the structural strength of the central steam stand column needs to be optimized and designed, so that the smooth production can be ensured.
Disclosure of Invention
The utility model aims at providing a mixing bunker center steam stand fixed knot constructs to above-mentioned condition, this fixed knot construct has effectively reduced because of the probability that center steam stand drops and leads to the production to be interrupted, the mediation and the change of the pipeline of being convenient for simultaneously.
The utility model has the following concrete scheme: mixing bunker center steam stand fixed knot constructs, including crossbeam, center steam stand and steam source inlet pipeline, center steam stand with adopt bayonet connection fixed mode between the crossbeam, the lateral wall upper shed of center steam stand and with steam source inlet pipeline detachable fixed connection.
Further, in the utility model discloses in bayonet junction department between central steam stand and the crossbeam adopts the helicitic texture to carry out fixed connection, and this helicitic texture is including the concave station of seting up on the crossbeam, establish the external screw thread on perforating hole, fastening nut and the central steam stand outer wall of concave station bottom, and central steam stand passes external screw thread and fastening nut threaded connection on the perforating hole and, and fastening nut blocks on the up end of the perforating hole of concave station bottom.
Further, the utility model discloses well opening on the central steam stand lateral wall with detachable connects the adoption between the steam source inlet pipeline that one section transition hose of screwed pipe joint cooperation connects, and wherein the opening part of screwed pipe joint welding on the central steam stand lateral wall, the both ends of transition hose are passed through the thread bush and are connected with steam source inlet pipeline and screwed pipe joint respectively.
Furthermore, in the present invention, the transition hose is a metal hose.
The utility model cancels the flange connection mode of the original central steam upright, adopts the integral central steam upright, adopts the plug-in connection and fixation mode between the upright and the cross beam, and adopts the fastening nut mode to fix the top end of the upright on the cross beam; change former steam source entry into crossbeam lower part pipeline admission by crossbeam center admission to adopt metal collapsible tube to connect the leading-in central steam stand of steam, the mediation and the change of the pipeline of being convenient for, through adopting the utility model discloses a fixed knot constructs, has effectively reduced because of the probability of the production interrupt that central steam stand drops and leads to.
Drawings
FIG. 1 is a schematic view of a steam column fixing structure in the center of a conventional mixing bunker;
fig. 2 is a schematic structural diagram of the present invention;
fig. 3 is a schematic diagram of the connection of the plug-in connection point between the central steam column and the cross beam of the present invention.
In the figure: the steam source comprises a steam source inlet pipeline, a beam, a flange, a welding point, a central steam upright post, a metal hose, a threaded pipe joint, a through hole, a fastening nut, a concave table and an external thread, wherein the steam source inlet pipeline comprises 2 parts, the beam comprises 3 parts, the flange comprises 4 parts, the welding point comprises 5 parts, the central steam upright post comprises 6 parts, the threaded pipe joint comprises 7 parts, a through hole comprises 8 parts.
Detailed Description
Referring to fig. 1-3, the utility model relates to a mixing bunker center steam stand fixed knot constructs, including crossbeam 2, center steam stand 5 and steam source inlet pipeline 1, center steam stand with adopt bayonet connection fixed mode between the crossbeam, center steam stand's lateral wall upper shed and with steam source inlet pipeline detachable fixed connection.
Furthermore, in this embodiment, the insertion-type connection point between the central steam column and the cross beam is fixedly connected by a threaded structure, the threaded structure includes a concave platform 10 formed on the cross beam, a through hole 8 formed at the bottom of the concave platform, a fastening nut 9, and an external thread 11 on the outer wall of the central steam column, the central steam column passes through the through hole and the external thread thereon is in threaded connection with the fastening nut, and the fastening nut is clamped on the upper end surface of the through hole at the bottom of the concave platform.
Furthermore, the detachable connection between the opening on the central steam stand lateral wall and the steam source inlet pipeline in this embodiment adopts threaded pipe joint 7 to cooperate with one section of transition hose to connect, wherein threaded pipe joint welds the opening part on the central steam stand lateral wall, and the both ends of transition hose are connected with steam source inlet pipeline and threaded pipe joint respectively through the thread bush.
Further, in this embodiment, the transition hose is a metal hose 6.
Traditional mixing bunker center steam stand is fixed with center steam stand and relevant flange welded connection, sets up the steam source entry in the inside of crossbeam simultaneously, and in case the welding point corroded back center steam stand will drop like this and lead to relevant production to appear interrupting.
The original welding structure is changed into threaded connection, and the central steam stand column and the cross beam are fixed in an insertion mode, so that the structural strength of a connecting point and a fixing point is guaranteed.
The utility model cancels the flange connection mode of the original central steam upright, adopts the integral central steam upright, adopts the plug-in connection and fixation mode between the upright and the cross beam, and adopts the fastening nut mode to fix the top end of the upright on the cross beam; change former steam source entry into crossbeam lower part pipeline admission by crossbeam center admission to adopt metal collapsible tube to connect the leading-in central steam stand of steam, the mediation and the change of the pipeline of being convenient for, through adopting the utility model discloses a fixed knot constructs, has effectively reduced because of the probability of the production interrupt that central steam stand drops and leads to.
In specific implementation process, the utility model discloses effectively reduced because of central steam stand drops the probability that leads to the production to be interrupted, can avoid consequently the problem to lead to the production interruption time about 48 hours each year, according to 350 tons productivity calculations per hour, can avoid the loss of about 48x370=17760 (ton) agglomerate each year.
