Abstract

A combustion furnace of energy-saving and environment-friendly type relates to combustion furnace in the system of drying and processing materials, belonging to the technical field of combustion furnace, used to overcome the shortcomings that coal is easy to accumulate in stoker that a complete burning of coal is affected. The combustion furnace comprises a furnace body, a stoker, a stoking bucket, an outlet flue, a blast chamber, a servo and a scummer. The stoker is divided into a fixed and a movable stoker which liaisons with the servo via a carriage. A blower air inlet is connected with the blower and an ash ejector on the bottom corresponds with a sink in the scummer. The improvement is that the fixed stoker and the movable stoker are alternatively arranged along the same inclined plane. The utility model eliminates the coal-accumulating effect brought by the conventional fixed and movable stokers arranged in tandem and creating an included angle, favorable for raw coal to be transferred to the stoker continuously and uniformly, favorable for complete and adequate combustion of coal seam, thereby enhances the combustion heat efficiency, reduces coal consumption, applicable for the combustion furnace supplying heat energy of high-temperature smoke-gas and in particular for the installation and utilization of combustion furnace in the system of drying and processing materials.

Description

Energy-Conservation Environment-Protecting Type Combustion Furnace

Technical field

The utility model relates to combustion furnace, and especially the combustion furnace in the dry materials treatment system belongs to the combustion furnace technical field.

Background technology

Disclose a kind of reciprocating combustion stove in China's No. 01260057 patent " muddy material drying facility ", body of heater, fire grate are arranged in the formation, added coal bunker, outlet flue, blast chamber, slag remover.The fire grate second half section is the moving grate that is obliquely installed, and preceding half section is horizontally disposed fixed grate, and moving grate is in transmission connection by steel-ball type carriage and servo, the rectilinear motion of writing in reply under servo drives.The air inlet of blast chamber is connected with air blast, the tank after the ash discharge of bottom in the water tank type scummer of corresponding body of heater below, this kind combustion furnace in use has following problem: the one, there is knuckle between moving grate that is obliquely installed and the horizontally disposed fixed grate, the knuckle place stockpiles coal easily, both have influence on coal-fired uniform continuously the conveying and supplied with, be difficult to the thermal efficiency and then the increase coal consumption that fully burning has influence on burning because of accumulating coal again; The 2nd, the ash discharging hole of blast chamber bottom is arranged in the water surface top of scummer tank, air blast and atmosphere moment communication when ash-draining gate is opened ash discharge, the high-temperature flue gas that contains a large amount of dust is escaped to overflow by ash discharging hole, has disturbed normal air blast, waste energy supply, also caused environmental pollution simultaneously., must improve for this reason, make it overcome above-mentioned defective existing combustion furnace.

Summary of the invention

Technical problem to be solved in the utility model provides the low Energy-Conservation Environment-Protecting Type Combustion Furnace of a kind of sufficient combustion power consumption.

The alleged problem of the utility model realizes with following technical scheme:

A kind of Energy-Conservation Environment-Protecting Type Combustion Furnace, body of heater 6, fire grate arranged in the formation, add coal bunker 2, outlet flue 13, blast chamber 3, servo 10, scummer 12, fire grate is made up of fixed grate 1 and moving grate 9, moving grate 9 is in transmission connection by carriage and servo, the air inlet of blast chamber 3 is connected with air blast 4, the tank 15 in the ash discharging hole of the bottom 14 corresponding scummers, its improvement is that described fixed grate 1 and moving grate 9 are intervally arranged along same inclined plane is alternate.

Above-mentioned Energy-Conservation Environment-Protecting Type Combustion Furnace, the inclination angle of described same inclined ramp are 13 °-15 °.

Above-mentioned Energy-Conservation Environment-Protecting Type Combustion Furnace, the ash discharging hole 14 of described blast chamber bottom is arranged in the water surface curve below of scummer tank 15.

The utility model adopts fixed grate and moving grate to be in the same clinoplain and is provided with, fixing, the forward and backward long-pending coal phenomenon of arranging and having angle of moving grate have been eliminated, helping raw coal is transported on the fire grate continuously uniformly, helping the coal seam burns cmpletely, and therefore strengthen combustion thermal efficiency, reduce coal consumption; In addition, the blast chamber bottom ash discharging hole that provides inserts the setting under the scummer tank water upper thread, wind-force and atmosphere are linked up the normal air blast of interference that causes in the time of can eliminating deslagging, high-temperature flue gas is escaped to overflow, disadvantages such as heat energy loss and contaminated environment, the utility model is suitable to providing the combustion furnace in the combustion furnace of high-temperature flue gas heat energy, especially the dry materials treatment system to install and use.

Description of drawings

Fig. 1 is the utility model structural representation:

Fig. 2 is the partial enlarged view of fire grate among Fig. 1.

The parts label is respectively in the accompanying drawing: the 1-fixed grate, and 2-adds coal bunker, 3-blast chamber, 4-air blast, the 5-chain and sprocket driving device, the 6-body of heater, ash bucket falls in 7-, 8-slag breaker, the 9-moving grate, 10--servo, 11-carriage, the 12-scummer, 13--outlet flue, 14-ash discharging hole, 15-tank, 16-are scraped and are pulled, the 17-chain, 18-sprocket wheel, 19-tail chain wheel, 20, the 21-supporting traverse.

The specific embodiment

Consult Fig. 1.Body of heater 6 is constructed body for steel structure body adds refractory brick.Add the corresponding fire grate of outlet of coal bunker 2, blast chamber 3 is the awl tubular, and the outlet of air blast 4 is connected with blast chamber 3 by pipeline, the corresponding fire grate of the outlet of each blast chamber 3, the air-supply of burning coal layer on fire grate exports and is ash discharging hole 14, when ash-draining gate is opened with slag emission in the scummer in 12.Scummer 12 by tank 15, be arranged in tank chain condition 7 and on scrape and pull 16 etc. and form, chain 17 is pile warp head, 18,19 rotations of tail chain wheel under the driving of chain and sprocket driving device 5, scrape to pull 16 and advance with it, in the traveling process bottom land slag are scraped and send out.Outlet flue 14 high-temperature flue gas heat energy floss holes dock with the inlet of drying machine etc.

Consult Fig. 1,2.Main improvement of the present utility model is, the fixed grate 1 during fire grate is formed and moving grate 2 interbody spacer setting mutually along same inclined plane, and promptly a fixed grate, a moving grate sequence interval are arranged.Fixing, activity is in the same inclined plane, and the inclination angle of same inclined ramp is 14 °.The two ends of the supporting traverse 20 of each fixed grate 1 are connected with fixed mount, the two ends of the supporting traverse 21 of each moving grate 9 then link to each other with steel-ball type carriage 11, carriage 11 is in transmission connection with servo 10, drives each moving grate 9 and do back and forth operation under servo 10 drives between two adjacent fixed grates 1.
