专利说明:
This invention relates to loading devices of a shaft furnace. The purpose of the invention is to increase the durability of the charging device of the shaft furnace by efficiently cooling its rotating parts and simplifying maintenance. FIG. 1 shows the proposed boot device, a vertical section; in fig. 2 - refrigerant supply unit, a section at the level of the nutritional channel; in fig. 3 ring block, vertical section at the level of the through-hole; in fig. And - a viewing opening in the ring block, a section; in fig. 5 details of the refrigerant; in fig. 6 mnemonic scheme of the cooling system. The drive mechanism of rotation of tray 1 contains two sets of interchangeable gears 2 and 3, which serve to ensure the movement of the ring 4 around the central hopper 5, and therefore the distribution tray 1 around the longitudinal axis of the furnace in accordance with its angular adjustment relative to this axis. The interchangeable gears 2 and 3 are rotated by the first and second engines (not shown). Movement from the set of interchangeable gears to the axles of the suspension of tray 1 is transmitted by means of a gear ring 6 and two gear boxes (not shown). The fixed housing 7 together with the rotary knob ring 4 limits the annular chamber 8 on the side, which is separated from the inside of the furnace by the case 9 of the tray suspension, which is integral with the rotating ring The walls of the housing 9 and the hopper 5 are directly exposed to the heat energy of the furnace. To protect the housing 9 from high temperatures and to avoid heat transfer through conduction or radiation to other parts, such as sub-bearings and gear wheels, several cooling coils 10 to 13 are installed around this housing (FIG. 1), in which tin water circulates. Each of these coils has a vertical pipe running along ring 4 connected to a co-feed tank 14. 92628 of an annular cross section formed by the outer wall 15 and the ring 4. By its side surface (ring 4) the reservoir 14 during rotation 5 of tray 1 slides in the inner groove of the ring block 16 mounted on the upper part 17 of the movable body 7. Two gaskets 18 and 19, attached by them to the outer wall of the tank 14, or to the inner surface of the groove of the block 16, prevent the penetration of the pie into the tank 14, not sealing. In block 16, a passage opening 20 is made to connect the tank 14 to the cooling water inlet pipe 21. Since the opening 20 and the pipe 21 are displaced relative to each other, their connection is provided by a horizontal annular groove 22, which, if there is only one pipeline 21, can encompass almost the entire annular 25 block 16. Water in the annular groove 22 provides cooling for block 16 (Fig. 2 and 3). For cleaning the tank 14, at least one access opening 23 (FIGS. 1 and 4) is provided, crossing the upper part 17 of the housing 7, as well as an annular unit 16. Water is drained from all cooling circuits through an annular manifold 24 fixed to the inner wall of the housing 7 (Figs. 1 and 5). To ensure rotation of the systems connected to the housing 9, the collector 24 has an annular lid fixed to the housing 9 and sliding along two walls forming the collector 24. Each of the cooling systems is connected to the collector fixed to the jib 25 of the duct 26 for removal by block 27 compounds. To compensate for thermal and mechanical deformations, each channel contains a pressure compensator 28. The lower surfaces of housing 9 are provided with insulating panels 29 ,. The heat-resistant steel sheets 30 are fastened to the walls of the body with a bolt 31 with a gasket 32 made of insulating fiber fabric that serves to eliminate the thermal bridges between chamber 8 and the inside of the furnace. The thickness of the insulation panels is about 95 mm. J The vertical walls 9 are provided with insulating panels 33, which, however, may be thinner, for example 25 mm, given that the vertical surfaces are less exposed to heat than the horizontal ones. There is a labyrinth pad between the frame and the rotary cim housing 9 for separating the chamber 8 from the inside of the furnace, which can be made as an annular groove 34 fixed to the housing 7 and connected to the circular strip 35 (the strip 35 enters the groove FOR) of the housing 9. In doing so, the labyrinth prevents dust from being suspended in the gas in the chamber 8 when pressure changes. At constant pressure, the penetration of dust is prevented by equalizing the pressure inside the chamber 8 and the pressure inside the furnace. In addition, a similar maze can be used between the fixed channel 5 and the rotating ring 4 in the form of a strip 36 between the housing 9 and channel 5. Between the reservoir 14 and the collector 24 are connected the cooling system 37 and the chute axis cooling system 38. The cooling water circulating between the manifold 24 and the reservoir 14 is provided by pumps 39. The coolant flow through the force of gravity depends on the distance between the reservoir 14 and the collector 24. In addition, the system contains a heat exchanger 40, a flow meter 41 and an automatic proportional valve 42 The auxiliary channel 43 with an automatic valve allows additional water to be introduced to compensate for losses due to evaporation. The emptying channel 44 is connected to an automatic valve 45. The water circulation in the cooling circuit is automatically controlled by four level meters connected to the reservoir and four level meters connected to the collector 24. In normal operation, the levels in the manifold 24 must be 92628 set between rain and max ,. If the level drops to min, a warning signal is given and the water is automatically supplied through the automatic valve 46. If the level continues to fall, the pumps 39 automatically stop at a level that does not idle. Vfpit elevations fQ level to max, as a result of the water supply through the channel 43, the valve 46 is automatically closed. If the level continues to rise, valve 45 automatically opens. . with ensuring the flow of water through the discharge channel 44 so that the water does not overflow and does not enter the furnace. In tank 14 with normal The functioning level must be between min, and maxj. If the level is reduced to min, the pumps 39 are turned on to full mode, and the valve 42 is fully de-activated. how Only the level rises to max /, the proportional valve 42 gradually reduces the flow and controls the operating mode of the pumps 39. When maXg is reached, the valve 42 is fully ea. sprays and pumps 39 stop. When the level drops below min, the automatic valve 46 opens to supply water through the collector 24, which should provide a lift Level 35 in the tank 14 under the action of pumps 39. If the level in the tank 14 continues to fall, a warning signal at the min2 level is activated, yakazi 4 indicating that 40 there is a leak on one of consumers 27 or 38, i.e. during normal operation, the levels in the reservoir and reservoir 24 should never reach the mark 45 min and exceed the mark of shah2 as non-compliance with this indicates a defect in the work, for example, leakage to the reservoir or collector 24 or at the level of consumers. The application of the invention provides an increase in the durability of the charging device of the shaft furnace due to its more efficient cooling. / 7 / t -, 4.
