Abstract
The invention discloses a method for installing a stock stopping wall of a circular cooler, belonging to the technical fields of sintering and palletizing. In the method, the stock stopping wall is independently suspended and fixed by using a stainless steel water-cooling beam, the weight of the stock stopping wall and the weight of a fire-retarding material are both borne by the stainless steel water-cooling beam which is fixed on supporting beams on an outer side and an inner side of the circular cooler, a rear side wall plate is completely free of stresses, and rectangular holes are formed on two sides of an upper cover of the circular cooler and are used for installation of the water-cooling beam; and supporting brackets are welded on the supporting beams on the inner side and the outer side of the circular cooler and used for supporting the water-cooling beam and the entire stock stopping wall, the water-cooling beam is fixed on supporting bases after the supporting bases are arranged, and fixing baffles are welded on the supporting bases at two sides of the water-cooling beam. The method disclosed by the invention has the advantages that the stock stopping wall and the rear side wall plate are completely separated, and the stock stopping wall is suspended by using the water-cooling beam, so that the stock stopping wall and the rear side wall are prevented from mutual influence in a working process; in addition, the fire-retarding materials of the stock stopping wall and the rear side wall plate are cast separately, so that the fire-retarding materials are prevented from influences due to interaction, and the stock stopping wall is ensured to work stably under a high-temperature condition.
Description
Technical field
The invention belongs to the agglomerates of sintered pellets technical field, particularly relate to a kind of installation method of central cooler stock retaining wall, solve the phenomenon that the oxidation of central cooler rear side wall panel causes stock retaining wall to come off.
Background technology
The central cooler stock retaining wall is the device of central cooler material receiving area and four cold sections partitions; Mainly get into four cold sections, guarantee the temperature of four cold sections oxidation balls, and block and fall the red ball of high temperature in order to the hot blast that stops material receiving area; Prevent that the red ball of material receiving area high temperature from dropping into finished belt, causes damage to belt.
The central cooler stock retaining wall adopts the mode of welding or bolt to be suspended on the rear side wall panel, and stock retaining wall and rear side wall panel junction refractory material adopt the integral type cast.The influence of the extruding force of oxidated ball comes off easily in the course of work, causes the rear side wall panel oxidation, causes stock retaining wall to come off.The stock retaining wall back production line maintenance of being forced to stop production completely that comes off because the material receiving area maintenance relates to the maintenance of heating and cooling process and refractory material, the repair time minimum 72 hours, have a strong impact on carrying out smoothly of production, increased production cost greatly.
Summary of the invention
The object of the present invention is to provide a kind of installation method of central cooler stock retaining wall, solve the phenomenon that the oxidation of central cooler rear side wall panel causes stock retaining wall to come off.
Novel stock retaining wall top is the water flowing water tank, and the bottom is the slow-witted piece of heat resisting cast steel, and water tank all has through hole up and down, and top is in order to hang fixedly stock retaining wall, and the bottom is in order to the slow-witted piece of fixing heat-resistant.At inboard pouring fireproof material, prevent that stock retaining wall from directly contacting high temperature air after the stock retaining wall installation.
The present invention is fixing with the suspension of stainless steel water-cooled beam separately with stock retaining wall; The weight of stock retaining wall and refractory material all is subjected to by stainless steel water-cooled joist support; The water-cooled beam is fixed on the brace summer in the outside in the central cooler; Rear side wall panel does not stress fully; Mounting means as shown in Figure 1; Rectangular opening is opened in cover both sides on the central cooler, in order to the water-cooled beam to be installed.Welding Support bracket on the supported on both sides beam inside and outside the central cooler,, after the bracket installation water-cooled beam is being fixed on the support bracket, and on the bracket of water-cooled beam both sides, welds fixed dam to support the weight of water-cooled beam and whole stock retaining wall.Will be independent of each other the stock retaining wall of avoiding former rear side wall panel scaling loss the to cause problem that comes off like this between stock retaining wall and the rear side wall panel.
Separately cast of anti-material with stock retaining wall and rear side wall panel; And in not having the space of anti-material, fill enough fire-resistant cotton; Just do not interact between stock retaining wall and the rear side wall panel like this; Stock retaining wall has slight rocking after stressed; But anti-material inside can not produce stress; Can not cause anti-material to come off, thereby avoid the too fast oxidation of rear side wall panel and stock retaining wall metal section and part.During ordinary production, water-cooled beam appearance temperature when guaranteeing that hydraulic pressure is 0.6MPa can not surpass 100 degree, has prolonged the service life of water-cooled beam greatly, has guaranteed the normal use of stock retaining wall.
Installation method of the present invention makes stock retaining wall separate fully with rear side wall panel; And stock retaining wall adopts the suspension of water-cooled beam; Avoided influencing each other in both courses of work; And the anti-material of stock retaining wall and rear side wall panel is cast separately; The influence of having avoided the anti-material of interaction partners to cause has guaranteed the steady operation of stock retaining wall under the hot conditions.
Description of drawings
Fig. 1 is the front schematic view of central cooler stock retaining wall.Wherein, the anti-material of the anti-material of cover 2 on rear side wall panel 1, the central cooler, circular cooler trolley 3, circular cooler trolley 4, connecting bolt 5, water-cooled beam 6, intake-outlet 7, stock retaining wall 8, central cooler brace summer 12, water-cooled beam supporting seat 13.
Fig. 2 is a stock retaining wall side section structure sketch map.Wherein, the anti-material of rear side wall panel 1, connecting bolt 5, water-cooled beam 6, stock retaining wall 8, stock retaining wall 9, the anti-material 10, fire-resistant cotton 11 of rear side wall panel.
The specific embodiment
Rectangular opening is opened in cover both sides on the central cooler, in order to the water-cooled beam to be installed.Welding Support bracket on the supported on both sides beam inside and outside the central cooler; To support the weight of water-cooled beam and whole stock retaining wall; After the bracket installation water-cooled beam is fixed on the support bracket, and on the bracket of water-cooled beam both sides, welds fixed dam, significantly swing occurs to prevent the stressed back of stock retaining wall.Show like Fig. 1; Stock retaining wall is fixed by bolts on the water-cooled beam; Connect the anchoring hook at stock retaining wall near the high-temperature region face down bonding; And by mode pouring fireproof material shown in Figure 2; Guarantee anti-material of stock retaining wall and the anti-material safe separating of rear side wall panel; Fill fire-resistant cotton in the last gap between water-cooled beam and rear side wall panel, alleviating of the erosion of material receiving area hot blast, and stop hot blast to get into four cold sections the stock retaining wall water tank.Transform the each maintenance in back and only the anti-material that partly weares and teares is repaired, shortened the repair time, guaranteed continuous production, greatly reduce production cost.
