Abstract

The utility model relates to a heater arranged on the furnace mouth of a coal burning water heating furnace. The utility model is characterized in that a water inlet pipe, a water outlet pipe and a by-pass pipe which is horizontally provided and communicated with the water inlet pipe and the water outlet pipe are arranged on the heater, and thus a stunted water circulation channel of the heater is formed to avoid the outward flashing of a water supplementing bracket caused by a steam chamber formed by water shortage in short time of the water jacket of the heater. Meanwhile, heat quantity can not be lost when the heater is moved apart the furnace mouth.

Description

A kind of coal stove fire door heater

The utility model is the heater that a kind of coal-fired hot-water heating stove fire door is provided with.

Existing water-jacket typ Coal stove with water heating means is a fuel with honeycomb briquette or smokelessly diffusing coal, and fire door can be heated up water and be cooked, but water jacket heat supply or heating.In order to utilize waste heat, a transportable heater generally all is set on fire door, remove when cooking, make its press seal when not cooking on fire door.These fire door heaters can be connected the heating pipeline with the serial or parallel connection form with furnace water jacket by forming with the corresponding dish type water jacket of fire door and water inlet pipe and outlet pipe on it.But when connecting heat supply with furnace water jacket, in case heater moves apart fire door, heater just becomes a radiator, influences the furnace water jacket heat supply heating; When its during with furnace water jacket heat supply in parallel, make the pipe-line layout complexity again, influence is manipulated, and serial or parallel connection no matter all can be not smooth because of water circulation in the heater water jacket, short time water shortage and form steam chest (criminal's of being commonly called as gas) and cause the outside flashing of moisturizing bucket.

Goal of the invention of the present utility model will provide a kind of exactly neither can form steam chest, does not influence the coal stove fire door heater of heat supply when moving apart fire door again.

Form by dish type water jacket and inlet tube that communicates with it respectively and outlet pipe and the bypass pipe that is communicated with water inlet pipe and outlet pipe for finishing coal stove fire door heater that goal of the invention designs.The mode of communicating of inlet tube, outlet pipe and bypass pipe can have three kinds, and the one, water inlet pipe is shorter than outlet pipe, and bypass pipe is horizontally disposed with, and pipe shaft is communicated with the water inlet pipe upper end, and a pipe end is communicated with the outlet pipe pipe shaft; The 2nd, bypass pipe is horizontally disposed with, and pipe shaft is communicated with inlet tube and outlet pipe upper port; The 3rd, bypass pipe is horizontally disposed with, and one port communicates with the inlet tube pipe shaft, and the another port is communicated with the outlet pipe pipe shaft.When using the utility model coal stove fire door heater, because dish type water jacket, water inlet pipe, outlet pipe and bypass pipe constitute a short and small heater water circulation path, thereby can avoid heater water jacket internal cause short time water shortage and form the outside flashing of moisturizing bucket that steam chest causes.Simultaneously, owing to water inlet pipe, outlet pipe and bypass pipe three pipes are interconnected, and connect with furnace water jacket, the water heater via water inlet pipe of being sent by the furnace water jacket outlet pipe enters the heater water jacket, and the heating pipeline is sent into by the heater outlet pipe in the heating back once more.When heater moved apart fire door, the hot water that furnace water jacket is sent here just can be directly through bypass pipe, and the heater outlet pipe is sent into the heating pipeline, and the heater water jacket of needn't flowing through again, thereby can avoid heat by heater water jacket distribution loss.

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

Fig. 2 is the utility model user mode figure.

Fig. 3 is two schematic diagrames of the utility model embodiment.

Fig. 4 is three schematic diagrames of the utility model embodiment.

As shown in Figure 1, water inlet pipe 4 and outlet pipe 2 are arranged on the dish type water jacket 1 of heater, bypass pipe 3 is horizontally disposed with, and its pipe shaft is communicated with water inlet pipe 4 upper ends, and left port is communicated with outlet pipe 2 pipe shafts.

As shown in Figure 2, fire door heater 10 places on the fire door 7, water inlet pipe 4 and outlet pipe 2 are arranged on the heater water jacket 1, and bypass pipe 3 is communicated with the downcomer 8 on the furnace water jacket 6 and outlet pipe of fire door heater 10 2 and heating pipeline connection through connecting flexible pipe 5 with upper hose 9 on the furnace water jacket 6.

As shown in Figure 3, water inlet pipe 4 and outlet pipe 2 are arranged on the dish type water jacket 1 of fire door heater, bypass pipe 3 is horizontally disposed with, and its pipe shaft is communicated with the upper port of water inlet pipe 4 and outlet pipe 2.

As shown in Figure 4, water inlet pipe 4 and outlet pipe 2 are arranged on the heater dish type water jacket 1, the two-port of bypass pipe 3 is communicated with the pipe shaft of water inlet pipe 4 and outlet pipe 2.

Claims

1, a kind of coal stove fire door heater is made up of dish type water jacket and the water inlet pipe that communicates with it respectively and outlet pipe, it is characterized in that also being communicated with between said water inlet pipe and the outlet pipe bypass pipe.

2, coal stove fire door heater according to claim 1 is characterized in that said water inlet pipe is shorter than outlet pipe, and bypass pipe is horizontally disposed with, and pipe shaft is communicated with the inlet tube upper end.One pipe end is communicated with the outlet pipe pipe shaft.

3, coal stove fire door heater according to claim 1 is characterized in that said bypass pipe is horizontally disposed with, and pipe shaft is communicated with inlet tube and outlet pipe upper port.

4, coal stove fire door heater according to claim 1 is characterized in that said bypass pipe is horizontally disposed with, and one port communicates with the water inlet pipe pipe shaft, and another port and outlet pipe pipe shaft limit are logical.
