Abstract

The utility model provides a multi-purpose oil burning tea-bath stove, which is composed of a stove body 1, a lower heat exchanger 2, a right flange disc 5, a clapboard 6, an upper heat exchanger 8, an upper water area 11, a flue gas box 14, a stove chamber 15, a left flange disk 16, an opening for installing burners 17 and a lower water area 19. The utility model is characterized in that the upper water area and the lower water area are isolated in the stove; the two water areas can be used singly, and two water outlets can also be communicated to be used in a concentrated way. The stove chamber 15 is connected with the stove body 1 by the flange disks, and the flange disks can be taken out of the stove body to be checked and repaired.

Description

A kind of novel multi-use oil burner

The utility model belongs to the boiler of thermo-mechanical machine class.

Mostly existing tea-bath furnace is with the coal to be fuel.The fuel oil tea-bath furnace began more and more gradually in recent years.But heat exchanger before structurally still having continued to use and the non-removable connected mode between the body of heater.This structure is very inconvenient when maintenance.Holding the pool in addition is impossible when the separation measure is not want to be used for for drinking-water and heating simultaneously with a stove.Being divided into the appearance pool up and down with the fuel oil tea-bath furnace more than the utility model provides, two districts are provided with two heat exchangers respectively, and between the high temperature section heat exchanger is together with flue and body of heater, taked the ring flange demountable structure, such stove can be drunk water simultaneously and be warmed oneself dual-purpose, the pool delivery port is connected together to focus on and uses on a kind of purposes about also can inciting somebody to action outside body of heater, when needing maintenance, the flue in following pool can take out from stove and overhaul in addition.

The purpose of this utility model provides an a kind of stove can realize multipurpose simultaneously, is convenient to the new structure that keeps in repair simultaneously again.Its technical measures are to divide two pools that separate with stove content pool, heat exchanger in last pool, being provided with separately, following pool and following heat exchanger wrap in the flue, take dismountable ring flange syndeton between flue and the body of heater, the flue that so just can realize the high-temperature fuel gas district can take out maintenance from dismounting in the stove, independent use can be realized in two pools, also the delivery port in two pools can be used in the connected set outside body of heater.

Be described with reference to the accompanying drawings many structures provided by the utility model with the fuel oil tea-bath furnace.Fig. 1 is a structural representation of the present utility model.Wherein body of heater 1 is a rectangular hexahedron, is made of inwall, outer wall and thermal insulation layer three parts.The inner chamber of body of heater 1 is divided into two ones up and down by dividing plate 6, left sleeve 16, left clapboard 20, right clapboard 21 and right sleeve 22, and top is divided into pool 11, and the bottom is divided into flue gas case 14.The equal Welding Structure of connecting portion between dividing plate 6, left sleeve 16, left clapboard 20, right clapboard 21 and the right sleeve 22, and these several all be welded to connect with inboard wall of furnace body and being connected also of body of heater bottom surface.Be provided with flue 15 in flue gas case 14, flue 15 is made up of flue housing, following heat exchanger 2, following heat exchanger tube 3, right flue 12, left flue 13, lower outlet 4 and water supplement port 23 and burner installing port 18.A left side flue 13 and right flue 12 are to link up the passage of heat exchanger 2 and flue gas case 14 down, and following heat exchanger tube 3 is arranged on down the heat exchanger tube of heat exchanger 2 inside, its quantity can be eight also can the six roots of sensation.Its arrangement mode is seen Fig. 3.Cavity is following pool 13 between following heat exchanger 2 and flue 15 housings.The burner installing port 18 of flue left end passes that left sleeve 16, left flange plate 17 and body of heater 1 communicate with the external world so that the install combustion device, and is not connected with body of heater, ring flange and left sleeve.Flue 15 is to put into and split out from the right side of body of heater 1.Be provided with heat exchanger 8 in last pool 11, it is a rectangular channel, is provided with heat exchanger tube 9 in passage, and last heat exchanger tube 9 is to make with steel high-frequency resistance welding (HFRW) spiral fin coil, and its quantity is 12, also can be 9, divides the staggered branch of three rows on horizontal segment.The lower port of last heat exchanger 8 communicates with the flue gas case, and the right-hand member outlet communicates with smoke exhaust pipe.Peak level face place is provided with breather pipe 10 and communicates with atmosphere above last heat exchanger 8, and last heat exchanger bottom is provided with upper water-out mouth 7.

Fig. 2 is that the structure that goes up heat exchanger 8 is replenished figure, shows quantity and the arrangement mode of going up heat exchanger tube in the heat exchanger 8, and the plan view shape of going up heat exchanger 8 passages is to be to become cylindrical shape by rectangle at right-hand member.

Fig. 3 is the quantity of heat exchanger tube 3 down and the shape of arrangement and right flue 12 and left flue 13.

Compared with prior art the utility model has the advantages that between flue 15 and the body of heater 1 and adopted the releasable connection scheme, service work is brought great convenience, be in body of heater, to be provided with pool 11 and 19, two pools, following pool respectively in stove, to separate and can realize that a stove satisfies simultaneously and drink water and the two kinds of purposes of warming oneself in addition.Outside body of heater, upper water-out mouth 7 is communicated with lower outlet 4 and then goes up pool and following pool and can focus on a kind of purposes and use, can unite use in two pools again.

The utility model has Figure of description three width of cloth:

Fig. 1 is the utility model structural representation, shape and the structure of having represented general structure scheme, body of heater 1 among the figure are provided with pool 11 and following pool 19 in the body of heater, be provided with pool heat exchanger 7 in last pool, set heat exchanger 2 in the following pool 19, the connected mode between flue 15 and the body of heater 1 etc.;

Fig. 2 is the quantity and the arrangement mode of heat-exchange finned tube 9 in the last heat exchanger 8, also is replenishing of Fig. 1, also can be 9 for its quantity that is staggered can be 12 between the heat-exchange finned tube.

Fig. 3 is the shape and the quantity of following heat exchanger tube 3 and right flue 12 and left flue 13 in the following heat exchanger 2, and following heat exchanger tube 3 can be 8, also can be 6, and central axis is avoided in its position as far as possible.
