Description

Water-boiling boiler

The utility model is a kind of drinking water boiler, belongs to a kind of boiling water and heating plant that is applied to buring solid fuel.

Pollute for reducing, restrictive regulation has been made to the use of the coal-fired stove that looses in many big and medium-sized cities of China, and advocates and use the moulded coal stove.And, use the boiler of general version but to exist the coal of moulded coal or change the comparatively problem of difficulty for drinking water boiler, and this boiler can only be used for the boiling water supply, thereby the scope of application is less, has also limited its utilization rate.For addressing these problems, people have designed the boiler that the combustion chamber can be pulled out from the water tank below, and the combustion chamber of this boiler is not suitable for the unit that has boiler because having only a burner, and it has limited the normal utilization of heat simultaneously.

The purpose of this utility model is: design a kind of high drinking water boiler of imitating applied widely, hot.

The utility model comprises boiler and combustion chamber, it has at least one combustion chamber and lays respectively in separately the calandria, each calandria is positioned at the outside of boiler below and comprises the air compartment of its housing, burner hearth and burner hearth below, leave coal filling hole on the housing of burner hearth top, and the gap between burner hearth upper end and its housing leads to the following bottom in boiler.Two to four calandrias generally can be settled in the below of boiler, and they can utilize each calandria coal filling hole to heat on the other hand, and this structure of the present utility model also be changed moulded coal easily to carrying out the boiler heating on the one hand.For making full use of the heat that moulded coal burning is produced, should have furnace wall water jacket and the upper water sleeve that communicates between each burner hearth and its housing, there is movable water jacket at the coal filling hole place, and upper water sleeve and movable water jacket communicate with boiler respectively.The top of boiler preferably has a steam guiding tube to lead in each air compartment, and the water vapour that enters air compartment can promote burning.The fixing cold water storage cistern in the boiler outside, it is gone to the bottom and leads to the water inlet of going to the bottom in the furnace wall water jacket, and the top of boiler has a hot steam pipe to lead in cold water storage cistern, utilizes the steam in the boiler that the cold water in the cold water storage cistern is carried out preheating.This hot steam pipe can be the arm of steam guiding tube.Guarantee that the water vapour in the boiler has enough pressure, and produce more water vapour, the increased pressure board of fixed belt hole is answered on the top of boiler, and has backed down venthole on boiler.The steam of being drawn by venthole can be used for steaming food.The water inlet of movable water jacket communicates with the bottom of boiler, and its delivery port links to each other with bath tube, and bath tube also communicates with the middle part of boiler.The utility model burns the water that can be directly used in shower, because the water in the boiler makes the several times heating of shower water through furnace wall water jacket, upper water sleeve, boiler, movable water jacket by bath tube and being connected of boiler middle part, make it reach the required temperature of shower.And when not required, the water side of bath tube can be closed, it is communicated with boiler, thereby can circulate heating the water in the boiler.Bath tube communicates with the top of boiler by valve.Flue is passed by the center of boiler, has the water pipe that two ends all communicate with boiler in the flue.The water inlet of cold water storage cistern has ball-cock assembly, finishes the automatic control of cold water storage cistern moisturizing thus.

Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.

Fig. 1 is the front view of present embodiment;

Fig. 2 partly cuts open figure for Fig. 1's;

Fig. 3 is the cutaway view of present embodiment rearview;

Fig. 4 is the A-A view of Fig. 3;

Wherein, 1-venthole, 2-boiler, 3-bath tube, the 4-dividing plate, 5-baking box, 6-movable water jacket, 7-calandria, the 8-increased pressure board, 9-water pipe, 10-flue, the 11-upper water sleeve, 12-housing, 13-furnace wall water jacket, the 14-steam guiding tube, 15-burner hearth, 16-air compartment, the 17-ball-cock assembly, the hot steam pipe of 18-, 19-cold water storage cistern.

Present embodiment comprises boiler 2, cold water storage cistern 19 and two calandrias 7.Each calandria 7 comprise two respectively by the air compartment 16 of housing 12, burner hearth 15, burner hearth 15 belows, be enclosed in the calandria 7 that the upper water sleeve 11 between the top and housing 12 on furnace wall water jacket 13 around the burner hearth 15, the burner hearth 15 and the movable water jacket 6 above the stockhole are formed.One baking box 5 is arranged between two calandrias 7, and boiler 2 and cold water storage cistern 19 are connected and are installed on the top of baking box 5, between the going to the bottom of baking box 5 and boiler 2 dividing plate 4 are arranged.Have slot between burner hearth 15 and the housing 12 in each calandria 7, the inner chamber of calandria 7 is communicated with gap between dividing plate 4 is gone to the bottom with boiler 2.From the going to the bottom upwards and pass boiler 2 of boiler 2, be fixed with the water pipe 9 that two ends all communicate with boiler 2 along the flue 10 of boiler 2 center lines in the flue 10.Be fixed with increased pressure board with holes 8 in the boiler 2 at an upper portion thereof, and heading tape there is venthole 1 on it.In the outside of boiler 2 bath tube 3 is arranged respectively for two calandrias 7, they communicate with the middle part and the bottom of boiler 2 by a valve respectively, the upper end of two bath tubes 3 joins and is controlled by a valve, their lower end is connected with the delivery port of movable water jacket 6, and the water inlet of movable water jacket 6 is connected to the bottom of boiler 2.The interface that wherein is in the top leads in the below of increased pressure board 8.On boiler 2 sidewalls of increased pressure board 8 tops to being circumscribed with a hot steam pipe 18, hot steam pipe 18 is divided into two arms outside boiler 2, one of them leads to respectively after two in the air compartment 16 of two calandrias 7 for steam guiding tube 14 extends downwards and is further divided into the gap of cold water storage cistern 19 by boiler 2; Another arm of hot steam pipe 18 feeds in the cold water storage cistern 19, and is bending therein.The water supplement port of cold water storage cistern 19 is positioned at its top, and ball-cock assembly 14 is installed.The outlet pipe of cold water storage cistern 19 leads to downwards in the water inlet of each calandria 7 furnace wall water jacket 13.Present embodiment leaves sewage draining exit at the water inlet pipe place of cold water storage cistern 19 bottoms and furnace wall water jacket 13.
