Abstract

The utility model relates to a feeding mechanism for a domestic garbage incineration furnace, which comprises a hopper, a backing board arranged below the hopper, a stuff cart and a push rod device connected with the back side of the stuff cart, wherein a sealing shell which can contain the stuff cart and can be in sealing connection with the backing board is arranged at the back of the hopper, a front opening is arranged on the sealing shell, and the opening is matched with a back opening of the hopper and is in sealing connection with the back opening of the hopper; a push rod hole in movable fit with a push rod in the push rod device is arranged on the back side surface of the sealing shell, and the opening of the push rod hole is provided with a heat resisting sealing ring. The utility model has good sealing performance, and effectively controls the leakage of fume. Because a hydraulic stuff pushing device with strong carrying capacity is adopted, the propulsion of the stuff cart is smooth, reliable and fast, and the failure rate is low.

Description

The feeding mechanism of domestic waste incineration

The utility model relates to the feeding mechanism of incinerator.

The Chinese patent application number how arched domestic waste incineration of 97206926.1 a kind of radiant type ladders of proposition, this stove is provided with feeding mechanism, this mechanism has hopper, the backing plate that the hopper below is provided with, hopper and backing plate all are fixed on the incinerator charger framework, backing plate is provided with lorry, and the both sides of lorry and bottom all have roller, and its rear side connects two parallel electric pushrods.Lorry is made back and forth movement under the effect of electric pushrod, house refuse continues to drop into from hopper on the backing plate of feed hopper bottom, constantly rubbish is pushed in the furnace chamber by lorry, so not only avoids rubbish to block at charging aperture, and can control inlet amount.But because lorry is when returning, flue gas can enter the after-frame space along with lorry, and the slot leakage by charger framework wall is polluted environment to the outside of incinerator.

The purpose of this utility model is to propose a kind of feeding mechanism of domestic waste incineration of favorable sealing property.

The utility model comprises backing plate, the lorry of hopper, hopper below, and the push rod device that is connected the lorry rear side, wherein the bottom of lorry has roller, the technical measures of being taked are to be provided with at the hopper rear can hold lorry and be sealedly connected on capsul on the backing plate, capsul is provided with open front, the after-opening of this opening and hopper coincide and is tightly connected, the trailing flank of capsul be provided with push rod device in push rod push-rod hole movingly, the push rod aperture is provided with heat resistant joint ring.

Above-mentioned push rod device is a fluid pressure type, forms push rod by piston rod and hydraulic cylinder, and Hydraulic Station is fixed on charger framework bottom.

Above-mentioned hopper is split type, and the hopper bottom adopts heat-resisting cast iron to make.

The utility model has been controlled the leakage of flue gas effectively owing to taked seal approach; Again owing to adopted the strong fluid pressure type pulling materials device of bearing capacity, make lorry advance steadily reliable and speed fast, each pusher time needs 60～70 seconds from original electric pushrod, foreshorten to 15～30 seconds, because power is big, avoid two push rods causing because of material is inhomogeneous asynchronous so that stuck phenomenon takes place, reduced fault rate; Heat-resisting cast iron is adopted in hopper of the present utility model bottom, can be cast with reinforcement, not only can bear higher temperature, and strengthened the intensity of hopper, simultaneously can on the leading flank of hopper, one pour into a mould a boss, with concrete cast body of heater the time, boss inserts body of heater, guarantees the sealing between body of heater and the hopper.

Fig. 1 is a configuration diagram of the present utility model;

Fig. 2 is the utility model lorry diagrammatic sketch.

Below in conjunction with accompanying drawing the utility model is further described.

The utlity model has hopper 6, the hopper below is provided with backing plate 7, hopper 6 and backing plate 7 all are fixed on the charger framework 4, lorry 2 is placed on the backing plate 7, the both sides of lorry and bottom all have roller 10,9, the lorry rear side connects the push rod 3 of two parallel fluid pressure type pulling lever apparatus, and push rod is made up of piston rod and hydraulic cylinder, and Hydraulic Station 5 is fixed on charger framework 4 bottoms.The front of hopper is provided with the opening 6-4 that communicates with burner hearth, and the back of hopper is provided with the opening 6-5 of lorry turnover.The hopper rear is provided with and can holds lorry and be sealedly connected on capsul 1 on the backing plate, the biside plate 11 of capsul adopts channel-section steel, the medial surface of biside plate 11 can be thought guide rail, two side wheels 10 of lorry contact with the medial surface of the biside plate of capsul, both play the guiding role, can reduce the resistance of motion of lorry again.Capsul 1 is provided with open front, and the after-opening 6-5 of this opening and hopper coincide and is tightly connected, the trailing flank of capsul 1 be provided with push rod device in push rod 3 push-rod hole movingly, the push rod aperture is provided with heat resistant joint ring 8.Hopper is split type, and top 6-1 adopts steel plate, and bottom 6-2 adopts heat-resisting cast iron, be cast with reinforcement on hopper, and one is poured into a mould a boss 6-3 on the leading flank of hopper.
