Abstract

The utility model relates to a novel side wall of the fire grate of the boiler. The utility model is an interlayer wind channel structure. The utility model is composed of an inner side steel plate, an outer side steel plate, an upper sealing plate, a lower sealing plate, a front sealing plate, a back sealing plate, reinforcing ribs and a partition plate. The utility model has the advantages that the phenomena of ash flying and slag deposit on the fire grate are solved; the cold wind is heated and is delivered to the fire grate; the burning speed is improved. The utility model is an ideal side wall device of the fire grate of the boiler.

Description

A kind of New-type boiler fire grate sidewall

The utility model relates to the boiler technology field, particularly relates to a kind of boiler grate sidewall.

At present, the fire grate both sides of existing double-body bike boiler are that lower furnace portion is to be built up by the dry type refractory material.Its shortcoming is that the furnace water cooling degree equals zero, and is deposited on the fire grate both sides after the flying dust slagging scorification, forces the boiler shutdown cleaning when serious.

The purpose of this utility model provides a kind of New-type boiler fire grate sidewall, with depositional phenomenon after the both sides flying dust slagging scorification of solution boiler grate.And deliver under the fire grate after making the cold wind heating, improve burning velocity.

The technical solution of the utility model is: the fire grate sidewall is the interlayer air channel structure, and it is by the medial and lateral steel plate, upper and lower shrouding, and forward and backward shrouding, reinforcement and dividing plate are formed.In, outside steel plate, on, following shrouding, before, the corresponding edge solid welding of back shrouding, dividing plate is at fire grate sidewall middle part, the dividing plate edge with in, outside steel plate, the solid welding of back shrouding inwall, the dividing plate front is a ventilating opening along with preceding shrouding spacing being arranged, in, the uniform reinforcement that is welded with between the steel plate of the outside, the place is evenly equipped with air outlet at the corresponding air compartment of inboard steel plate Lower Half, and air inlet is arranged at back shrouding top, air inlet edge and the solid welding of angle steel flange dish, before the fire grate sidewall, connection interface, a left side are arranged at rear inside steel plate top, be communicated with interface respectively with preceding before and after the right fire grate sidewall, the crossbeam termination solid welding of back air channel

The utility model compared with the prior art because the boiler grate both sides are designed to the interlayer wind apparatus, its advantage is that the furnace water cooling degree is increased, and is not deposited on the boiler grate both sides after the flying dust slagging scorification, and delivers under the fire grate after making the cold wind heating, improves burning velocity.

Description of drawings:

Fig. 1 is a kind of New-type boiler fire grate sidewall front view section of structure.

Fig. 2 is a kind of New-type boiler fire grate sidewall A-A profile.

Provide the utility model most preferred embodiment below in conjunction with accompanying drawing: the fire grate sidewall is the interlayer air channel structure.It is by medial and lateral steel plate 1,2, upper and lower shrouding 3, and preceding shrouding 4, back shrouding 5, reinforcement 6 materials [form by 12Q235-A and dividing plate 7.Other material is the 6-10mm steel plate, in, outside steel plate 1,2, on, following shrouding 3, before, back shrouding 4,5 corresponding edge solid weldings, dividing plate 7 is at fire grate sidewall middle part, dividing plate 7 edges with in, outside steel plate 1,2, back shrouding 5 inwall solid weldings, dividing plate 7 fronts are ventilating opening along with preceding shrouding 4 spacing being arranged, in, outside steel plate 1,2 uniform reinforcements 6 that are welded with, the place is evenly equipped with air outlet at the corresponding air compartment of inboard steel plate 1 Lower Half, air inlet is arranged at back shrouding 5 tops, air inlet edge and 8 solid weldings of angle steel flange dish are before the fire grate sidewall, connection interface, a left side are arranged at rear inside steel plate top, be communicated with interface respectively with preceding before and after the right fire grate sidewall, the crossbeam termination solid welding of back air channel.During use, angle steel flange dish 8 cooperates with blower fan, and wind is admitted in the interlayer air channel, dividing plate 7 top, sends into air channel, dividing plate 7 below through dividing plate 7 fronts along ventilating opening, be blown in the burner hearth by inboard steel plate 1 air compartment port, the air channel crossbeam tends to balance left and right fire grate side wall temperatures.

Claims

1, a kind of New-type boiler fire grate sidewall, it is characterized in that: the fire grate sidewall is an interlayer wind structure, it is by interior, outside steel plate, on, following shrouding, before, back shrouding, reinforcement and dividing plate are formed, in, outside steel plate, on, following shrouding, preceding, the corresponding edge solid welding of back shrouding, dividing plate is at fire grate sidewall middle part, the dividing plate edge with in, outside steel plate, the solid welding of back shrouding inwall, the dividing plate front is a ventilating opening along with preceding shrouding spacing being arranged, in, the uniform reinforcement that is welded with between the steel plate of the outside, the place is evenly equipped with air outlet at the corresponding air compartment of inboard steel plate Lower Half, and the back shrouding first half has air inlet, and the air inlet edge cooperates solid welding with the angle steel flange dish, before the fire grate sidewall, connection interface, a left side are arranged at rear inside steel plate top, before the right fire grate sidewall, the back is communicated with interface respectively with preceding, the crossbeam termination solid welding of back air channel.
