Abstract

The utility model discloses a novel condensed steam reclaimer which relates to a steam-reclaiming, energy-saving device. The condensed steam reclaimer comprises an electric motor, a combined gearbox, a crank link, a guiding mechanism, a reciprocating piston type compression cylinder and a check valve. A shaft seal arranged on the front end of the compression cylinder comprises a plurality of composite seal rings which are pressed in the seal grooves of a sealing base by a gland bush; a compression piston is provided with a plurality of T-shaped piston rings; and a valve core and a valve rod of the check valve are made of high-wearability composite material. Since the high-wearability elastic composite seal rings are employed as the shaft seal of a piston shaft, the sealing effect is good, and the service life is long. Since a plurality of T-shaped piston rings are employed, steam cannot be leaked, pressure cannot be reduced, and therefore the efficiency of compression and recovery is high. Since the valve core and the valve rod of the check valve are made of high-wearability composite material, the service life is greatly prolonged, and reparation is convenient. An energy-saving inertial belt pulley is added on the combined gearbox, the design of the gear chain is reasonable, output is carried out at the center of a crankshaft, operation is stable, energy can be saved, and mounting and use are flexible.

Description

Novel condensing vapour reclamation machine

Technical field:

The utility model relates to condensed water and exhaust steam to the power economized boiler random that boiler reclaims, and mainly is meant a kind of compression condensing vapour reclamation machine.

Background technology:

Disclosed condensing vapour reclamation machine mostly is split type, mainly constitute by motor, gearbox, eccentric, guiding mechanism, piston type compressed cylinder, one way stop peturn valve etc., its effect is that boiler is returned in the exhaust steam and the compressed cylinder compression of condensed water of will discharge with thermic devices again, to reach UTILIZATION OF VESIDUAL HEAT IN, energy-conservation purpose, the subject matter that disclosed condensing vapour reclamation machine exists is all part split designs, the big power consumption of volume is high, the compression cylinder sealing is poor, leak vapour, organic efficiency is low, the sealing part abrasion piece, the maintenance cost height, influence runs well.Up-to-date a kind of integral type condensing vapour reclamation machine disclosed, be that gearbox, eccentric, guiding mechanism are integrated, be connected with compression cylinder again, little complete machine compactness takes up space, its weak point is: the one, there is compound transmission train design defectiveness, and make its power consumption big, eccentric and guiding mechanism depart from the center and are provided with, be inclined to one side head output, it is poor to cause exporting stationarity; And eccentric throw is little, and piston stroke is short, the reciprocating frequence height, and compression efficiency is low: the 2nd, still adopt asbestos packing and pot type piston ring etc. to make encapsulant and seal, the problem that unresolved compression cylinder sealing is poor, leak vapour, organic efficiency is low, seal is easy to wear; The 3rd, problems such as unresolved present check-valves metal spool rapid wear is not wear-resisting, spool repair and replacement inconvenience.

Summary of the invention:

The goal of the invention of the utility model, be at prior art it: compound transmission design is reasonable inadequately; The compression cylinder the axis of the piston seals and piston ring packing is poor, the seal rapid wear; Check-valves is defective such as wear-resisting rapid wear not, and it is carried out bigger improvement, and a kind of novel condensing vapour reclamation machine is provided.

The foregoing invention purpose is achieved by following technical measures, novel condensing vapour reclamation machine, comprise base 11, motor 1, combiner gearbox 3, crankshaft-link rod 6, fairlead 7, guide piston 8, the axis of guide 9 connects the axis of the piston 13 through connector 10, the compression piston 14 that is loaded on the axis of the piston has piston ring 15, condensing compression cylinder 12 cylinder body front ends have shaft sealer, the compression cylinder condensing is imported and exported and is connected to check-valves 24 and 24 ＇ respectively, be characterised in that, described compression cylinder cylinder body front end shaft sealer is for being placed on the axis of the piston 13, the a plurality of high-wearing feature elastic composite sealing rings 19 that are pressed on by gland 20 in the seal groove of seal receptacle 18 constitute, and sealing ring 19 its sections are flat convex; Sealpiston-ring 15 its sections of described compression piston are "T"-shaped, are arranged side by side a plurality ofly, and the lateral part that it is in piston face, contact with cylinder sleeve 17 perhaps, interlaces folded joining each other each other mutually near contact.

To change energy-conservation inertia belt wheel 2 into the input small pulley that motor 1 band is in transmission connection; Described combiner gearbox 3 is by being meshed with gear 4b with the coaxial gear 4a of energy-conservation inertia belt wheel 2, being meshed with gear 4d with the coaxial gear 4c of gear 4b, constituting with the coaxial bent axle 5 hinge connection connecting rods 6 of gear 4d; Strengthen the crankshaft eccentric radius,, be increased to 60 by former not enough 60mm---100mm.

Its spool 25 of described check-valves is overlooked and is like gear-like, crosses tank 28 when inter-tooth slots constitutes valve opening, and spool has vertical valve rod 26, and the valve rod upper end is inserted in the pilot hole 27 and can be moved up and down, and stem surface has a plurality of vertical steam discharge grooves 29; Spool, valve rod are made by the high abrasion composite.

The beneficial effect that the utility model produced is, because of the flat male seal circle that has adopted the high abrasion elastic composite to make is made the axis of the piston sealing, good sealing effect, long service life; Adopted multiple tracks T shape piston ring, do not leaked vapour, do not reduce pressure, compression organic efficiency height; Its spool of check-valves adopts the high abrasion composite to make, and has prolonged service life greatly, and easy to maintenance; Combiner gearbox is set up energy-conservation inertia belt wheel, and train is reasonable in design, and the output of arc crankshaft center operates steadily, energy-conservation, the inertia belt wheel can about two exchange and install, increased the use flexibility; Strengthened the crankshaft eccentric radius, compression frequency is low, and the compression efficiency height.
