Abstract
The utility model relates to a front axle lubricating and cooling device for a boiler, which comprises a horizontal cooling pipe and a water inlet pipe and oil pipes which are sheathed in the cooling pipe, wherein the left end and the right end of the cooling pipe are sealed with a left block plate and a right block plate by soldering; the water inlet pipe and the oil pipes are inserted in the left block plate; the extension ends of all oil pipes are led out from the side wall of the cooling pipe at intervals according to oil injection positions of a grate driving axle bearing lubricating system; and the leading-out ends are assembled with oil pipe connectors. The front axle lubricating and cooling device has simple structure, adopts the independent structure of the oil pipes, has high water capacity and high cooling speed, and can effectively prevent scaling of the cooling pipe. The front axle lubricating and cooling device combines soldering, expanded joint and screw joint together, and has convenient assembly, disassembly and maintenance. By effective cooling of the cooling pipe, the oil pipes do not deform or break, thus leading to stable running of the boiler.
Description
One, technical field: the utility model relates to a kind of boiler front axle lubricating and cooling.
Two, background technology: the large-sized boiler that concentrated supply of heating in the city is used generally adopts the compound fire grate of chain, the fire grate front axle by two that are symmetrically arranged separately independently driving shaft form, three bearings of every driving shaft adapted, each bearing is provided with fixing lubricating system, after use through a heating phase, lubricating system is owing to be under the hot environment for a long time, oil pipe often appears, cooling water pipe fouling phenomenon of blocking, cause the oil pipe torsional deformation, even rupture, thereby cause axle journal and bearing bush abrasion, equipment often need keep in repair, and heat supply is forced to interrupt.
Three, summary of the invention: the purpose of this utility model is to propose a kind of compact conformation, can effectively prevent tubing deformation, fracture, the boiler front axle lubricating and cooling that cooling tube is less scaling.
The purpose of this utility model is achieved in that boiler front axle lubricating and cooling is made up of horizontal cooling tube and the water inlet pipe and the oil pipe that are wrapped in the cooling tube, sealing has left and right closure plate at two ends, the cooling tube left and right sides, on left closure plate, be inserted with water inlet pipe and oil pipe, each oil pipe stretches into the oil filler point position of termination according to fire grate driving shaft bearing lubricating system, keep at a certain distance away and drawn by the cooling tube sidewall, lead is equiped with oil connection.
The utility model is simple in structure, and oil pipe adopts absolute construction, and water capacity is big, and cooling is fast, can effectively prevent the cooling water pipe fouling.Adopt the comprehensive of welding, expanded joint and wire connection, this device dismounting, keep in repair convenient.By effective cooling of cooling water pipe, oil pipe can not deform, phenomenon of rupture, can make stable operation of the boiler.
Four, description of drawings: concrete structure of the present utility model is provided by following drawings and Examples:
Fig. 1 is a boiler front axle lubricating and cooling structural representation.
Legend: 1, left closure plate, 2, discharge outlet, 3, cooling tube, 4, water inlet pipe, 5, oil pipe, 6, right closure plate, 7, demarcation strip, 8, connecting hole, 9, oil connection, 10, tube connector.
Five, the specific embodiment:
The utility model is not subjected to the restriction of following embodiment, can determine concrete embodiment according to the technical solution of the utility model and actual conditions.
Embodiment: as shown in Figure 1, boiler front axle lubricating and cooling is made up of horizontal cooling tube 3 and the water inlet pipe 4 and the oil pipes 5 that are wrapped in the cooling tube 3.Cooling tube 3 is a cavity pipe, is equiped with discharge outlet 2 in its outer wall upper left side.Sealing has left and right closure plate 1,6 at two ends, cooling tube 3 left and right sides.Be connected to vertical demarcation strip 7 near right closure plate 6 face down bondings in cooling tube 3, demarcation strip 7 has the two through hole of arranging up and down, and following side through hole is a connecting hole 8.Demarcation strip 7 is divided into two chambeies left large and right small with cooling tube 3, and two chambeies are communicated with by connecting hole 8.Have four holes on left closure plate 1, wherein a hole is positioned at top, the center of circle, is inserted with water inlet pipe 4 in this hole, and water inlet pipe 4 other ends penetrate in the last side through hole of demarcation strip 7, and the end is positioned at cooling tube 3 right side areolas; Other three holes are down equilateral triangle arranges, and is positioned at below, left closure plate 1 center of circle, all is inserted with oil pipe 5 in each hole.Each oil pipe 5 stretches into the oil filler point position of termination according to fire grate driving shaft bearing lubricating system, keeps at a certain distance away and is drawn by cooling tube 3 sidewalls, and lead is equiped with oil connection 9.Can be communicated with tube connector 10 at oil connection 9 places, tube connector 10 end is in addition also installed oil connection 9, and the oil filler point of this oil connection 9 and fire grate driving shaft bearing lubricating system is communicated with.
Three independent oil pipes 5 are wrapped in the single cooling tube 3, cooling water is entered in the cooling tube 3 right loculuses by water inlet pipe 4, enter big chamber, cooling tube 3 left sides through connecting hole 8 revolutions again, discharge by cooling tube 3 left side discharge outlet 2 at last, the cooling water flow path of this kind " oil-in-water " formula can make oil pipe 5 contact with cooling water to greatest extent, effectively reduce in the oil pipe 5 extremely around temperature.Solved soluble mineral matter decomposes fouling in the water, lubricating oil high-temp volatilization, dry, and the profit pipeline blockage problem that causes.
Above technical characterictic has constituted most preferred embodiment of the present utility model, and it has stronger adaptability and best implementation result, can increase and decrease inessential technical characterictic according to actual needs, satisfies the needs of different situations.
