Abstract

The utility model provides a novel side sealing device of a trolley type heating furnace. The side sealing device is provided with a sealing groove, wherein a heat-insulation sealing material is distributed in the sealing groove and the sealing groove is adhered to a furnace wall sealing knife fixed on a furnace wall and a trolley sealing knife fixed on the trolley in a sealing manner, an inclined iron is fixedly connected on the lower end surface of the sealing groove, a fixing frame on which the inclined iron can slide up and down is fixed on a furnace body, and an air cylinder pushing-pulling device which is matched with the inclined iron and can push the inclined iron to raise and press or descend and separate from the sealing groove is arranged below the inclined iron. According to the utility model, the air cylinder pushing-pulling device is adopted to provide a power source, the inclined iron is driven to slide relatively by being supported, so that the up-and-down movement of the sealing groove is realized and the sealing groove is ensured to be raised to be tightly close to the furnace wall sealing knife 10 and the trolley sealing knife 11 after a trolley enters the furnace body, and a gap is tightly sealed; when the trolley goes out of the furnace, the sealing groove is descended to be convenient for the trolley to move; and therefore, the heat treatment quality of a workpiece is ensured, the energy utilization rate is improved, and energy loss and environment pollution caused by furnace gas leakage are also prevented.

Description

Novel trolley type heating furnace side-sealing device

Technical field

The utility model belongs to the Equipment for Heating Processing technical field, is specifically related to a kind of novel trolley type heating furnace side-sealing device.

Background technology

Metal heat treatmet is one of important process in the machine-building, and it mainly through to workpiece heating, insulation, cooling, accomplishes Technologies for Heating Processing such as annealing, tempering, quenching, normalizing, changing the microscopic structure of interior, thereby improves the serviceability of workpiece.Trolley type heating furnace is one of the equipment comparatively widely of using in the Technology for Heating Processing; Owing to consider the needs that the chassis turnover is moved; Usually body of heater is separated with body construction during design; Between furnace wall and chassis, reserve certain interval, thereby formed the loss position of heat, must cause serious thermal loss.Compare with batch-type furnace, guarantee that sealing is the maximum weakness of car type furnace.At present; That uses in the most of at home chassis of the sand sealing groove sealing mechanism manufacturing firm is more, is a more original car type furnace encapsulation scheme, fills sand between this sealing mechanism dependence sand launder and the sealing cutter and seals; Its deficiency is; Sand seriously runs off in the groove along with the frequent turnover of chassis makes, thereby causes poorly sealed furnace gas loss, has increased the extra cost because of changing, replenishing sand simultaneously.Therefore, improving the car type furnace sealing mechanism, is to ensure heat treatment of workpieces quality and the urgent task of realizing energy-saving and emission-reduction.

The utility model content

The technical problem that the utility model solves: a kind of novel trolley type heating furnace side-sealing device is provided, and seal groove is processed by channel-section steel, interior dress aluminosilicate refractory fiber flame-proof thermal insulation material; The reservoir push-pull device at fixed provides power source; Through supporting the relative slip of wedge jockey, realize moving up and down of seal groove, thereby guaranteed after chassis gets into body of heater; Seal groove is raise be close to furnace wall sealing cutter 10 and chassis sealing cutter 11, the tight gap of sealing; The seal groove height descends before chassis is come out of the stove, and is convenient to chassis and moves, and has so both guaranteed the heat treatment of workpieces quality to have improved energy utilization rate again, has also prevented energy loss and environmental pollution that furnace gas leakage is brought.

The technical scheme that the utility model adopts: novel trolley type heating furnace side-sealing device; Has seal groove; The furnace wall sealing cutter of laying heat-insulating and sealing material and seal groove in the said seal groove and being fixed on the furnace wall is closely connected with the chassis sealing cutter that is fixed on the chassis; The seal groove lower surface is fixedly connected wedge; Be fixed with the fixed mount that can supply wedge to slide up and down on the body of heater within it, said wedge below is provided with suitable with wedge and can promotes wedge and seal groove raise compress or reduce the reservoir push-pull device at fixed that separates.

Wherein, said heat-insulating and sealing material is an aluminosilicate refractory fiber.

Wherein, said seal groove adopts No. 22 channel-section steels to process.

Wherein, said reservoir push-pull device at fixed is formed by supporting wedge, wind bar and reservoir, and said reservoir output connects wind bar one end, and said support wedge is located at the wind bar other end and suitable with wedge.

Further, be fixed with a plurality of fixed mounts on the said body of heater, said seal groove lower surface is fixedly connected a plurality of wedges, said wedge all place in the fixed mount and the wedge lower surface all suitable with the support wedge upper surface of push-pull device at fixed.

The utility model advantage compared with prior art:

1, simple in structure, to adopt reservoir push-pull device at fixed push-and-pull support wedge to drive wedge and do to slide relatively, the rising of realization seal groove compresses with reducing and separates, and the bump to seal groove when having avoided the chassis turnover damages;

2, easy and simple to handle, the rising seal groove sealed after chassis advanced stove, reduced the seal groove depressurization before chassis is come out of the stove, for chassis turnover stove facilitates;

3, good airproof performance, reservoir push-pull device at fixed can provide the enough power maintenance seal grooves and the closely connected impaction state of furnace wall sealing cutter chassis sealing cutter, guarantee that furnace gas does not leak;

4, improve effective utilization rate of energy 3%.

The specific embodiment

A kind of embodiment of the utility model is described below in conjunction with accompanying

drawing

1,2,3.

Novel trolley type heating furnace side-sealing device; Has seal groove 1; Seal groove 1 adopts No. 22 channel-section steels to process; It is closely connected with the chassis sealing cutter 11 that is fixed on the chassis 8 with the furnace wall sealing cutter 10 that is fixed on the furnace wall 7 to lay heat-insulating and sealing material 2 and seal groove 1 in the said seal groove 1, and said heat-insulating and sealing material 2 is an aluminosilicate refractory fiber, and seal groove 1 lower surface is fixedly connected wedge 4; Be fixed with the fixed mount 5 that can supply wedge 4 to slide up and down on the body of heater 12 within it, said wedge 4 belows are provided with suitable with wedge 4 and can promote wedge 4 and seal groove 1 raise compress or reduce the reservoir push-pull device at fixed that separates.Said reservoir push-pull device at fixed is formed by supporting wedge 6, wind bar 3 and reservoir 9, and said reservoir 9 outputs connect wind bar 3 one ends, and said support wedge 6 is located at wind bar 3 other ends and suitable with wedge 4.Be fixed with a plurality of fixed mounts 5 on the said body of heater 12, said seal groove 1 lower surface is fixedly connected a plurality of wedges 4, said wedge 4 all place in the fixed mount 5 and wedge 4 lower surfaces all suitable with support wedge 6 upper surfaces of push-pull device at fixed.
