Abstract

The utility model relates to the improvement of an energy-saving coal stove, a coal core of the coal stove and an insulating layer which is arranged at the outer side of the coal core are positioned in the water tank, the upper and lower ends of an insulating layer outer wall (a barrel body which is filled with insulating material) are respectively fixed on upper and lower walls (no water leakage) of the water tank tightly, a wall of the water tank are respectively connected with a water inlet pipe and a water outlet pipe, and the water inlet pipe is communicated with the water outlet pipe by a small metal pipe. When the coal stove is used, the water tank is full of water, the insulating layer outer wall of the coal stove is used to heat the water in the water tank; when tap water passes through the small metal pipe, the tap water is heated by water storage bath in the water tank first, and then, the top water enters into a life hot water pipe network.

Description

A kind of Energy-saving coal stove

The utility model relates to a kind of Energy-saving coal stove.

Coal stove is widely used in China rural area, samll cities and towns and some Greater, big city families or restaurant as a kind of cooking utensils at present, and widely used coal stove has following three kinds in family or the restaurant now:

First kind, do not utilize coal stove insulation lateral heat transfer heating domestic water fully.The advantage of this coal stove is simple structure, low price, but uses uneconomical.Second kind, utilize coal stove insulation lateral heat transfer heating domestic water.Domestic water is heated around being centered around heat-insulation layer, and the relative atmosphere of domestic water does not have pressure, so can only be by dipping use.This coal stove advantage is to use economy, but domestic water makes things convenient for (not having except the running water condition) inadequately by dipping use.The third also utilizes coal stove insulation lateral heat transfer heating domestic water.Heated domestic water inlet is connected on the water supply pipe around being centered around heat-insulation layer, and heated domestic water is with respect to atmospheric sealing, and it is local with convenient use to guide to publilc baths, pond etc. by pipeline after being heated.This coal stove has overcome the shortcoming of second kind of coal stove, but because the tank box wall of the heated domestic water of splendid attire will bear tap water pressure, box body wall must be very thick, cost is also inevitable high, if do box body wall with straight carbon steel then be easy to generate rust water, then cost is higher to do box body wall with other material (such as stainless steel); Another shortcoming of this coal stove is to cause the box body wall explosion because of misoperation produces the steam high pressure easily.

The utility model is in order to overcome above-mentioned every the deficiencies in the prior art, and provides that a kind of cost is lower, not explosion, rustless water, utilizes the novel coal stove of coal stove insulation lateral heat transfer heating domestic water.

The purpose of this utility model can reach by following measure: two ends closely are fixed on the last lower wall (water-tight) of a water tank about the cylindrical shell of splendid attire coal stove insulation material, on water tank wall, connect a water inlet pipe and an outlet pipe respectively, be communicated with by one or more metallic sheath between water inlet pipe and the outlet pipe.Fill with water when coal stove uses in water tank, the relative atmosphere of water tank internal cavity does not have pressure, and the water tank inner storing water is heated by the cylindrical shell of splendid attire coal stove insulation material; When the needs domestic hot-water, running water through water inlet pipe by in the water tank during metallic sheath by water tank cavity water storage water-bath heating, enter domestic hot-water's pipe network through outlet pipe then.

That the utility model will be further described is as follows below in conjunction with accompanying drawing:

Accompanying drawing is the utility model cutaway view.

One ring-like cavity is arranged between coal core 1 and the cylindrical shell 3, middle fill insulant material 2, coal core 1 is supported by coal-fired support stick 5, and coal-fired support stick 5 is fixed on cylindrical shell 3 inwalls, and coal-fired support stick 5 belows have coal ash outlet 4 (double as combustion air inlet) two ends to be separately fixed on cylindrical shell 3 and water tank 6 walls.Cylindrical shell closely is fixed on the last lower wall (water-tight) of water tank 6 in two ends about in the of 3.Be connected to a water injection pipe 11 and a water inlet pipe 7 at water tank 6 one sidewalls, connect an outlet pipe 8 at water tank 6 other end sidewalls, be communicated with by several metallic sheaths 12 between water inlet pipe 7 and the outlet pipe 8, metallic sheath 12 radicals, size, length are determined by the water situation, metallic sheath 12 general coileds, also can curve other shape, metallic sheath 12 is positioned at water tank 6 internal upper parts.Water injection pipe 11 openings are in water tank 6, and water inlet pipe 7, outlet pipe 8 and metallic sheath 12 be equal imperforation in water tank 6.Be connected to a relief tube 9 and blow-off pipe 10 in water tank 6 bottoms.

Structure described in the utility model water injection pipe 11 and water inlet pipe 7 in use is connected on the running water pipe, and outlet pipe 8 is connected on domestic hot-water's pipe network inlet, utilizes water injection pipe 11 to fill with water in water tank 6.Coal is in coal core 1 internal combustion, and burning of coal heat is last by the water storage in cylindrical shell 3 heating water tank 6 by coal core 1 and insulation material 2.Each valve can be opened water on domestic hot-water's pipe network when the water storage comparative heat in the water tank 6, at this moment, running water enters metallic sheath 12 from water inlet pipe 7 and heats through water-bath in water tank 6, enters domestic hot-water's pipe network through outlet pipe 8 then, what like this, each valve flowed out on domestic hot-water's pipe network is hot water.
