Heating boiler with lifting pressing plate for crushing furnace slag

Abstract

The invention discloses a heating boiler with a lifting pressing plate for crushing furnace slag. The heating boiler comprises a shell, a feeding hopper, a combustion chamber, a heating chamber and afurnace slag collecting cavity, the shell is internally partitioned into the combustion chamber, the heating chamber, the furnace slag collecting cavity and a smoke channel, and a bearing is fixed toa center shaft of a pressing plate. A vertical operating rod is fixedly inserted into the bearing, the pressing plate comprises a fixed mesh plate, an open-close mesh plate, hinges and clamp protrusions, and a horizontal shifting rod is fixed to the operating rod. A horizontal limiting rod is further fixed to a guiding sleeve, a water sleeve is fixed into the heating chamber, and two partition plates are fixed into the smoke channel. A heat exchange pipe is arranged in the smoke channel in a penetrating mode. According to the heating boiler, through the arranged pressing plate, the generated furnace slag can be crushed to be refined and then falls at the bottom from holes of a furnace grill to be collected, people do not need to hold a tool by hands to stretch into the heating chamber to conduct clearing, operation is convenient, personnel are prevented from being burned, and personnel safety is achieved.

Description

technical field [0001] The invention relates to a boiler, in particular to a heating boiler with a lifting pressure plate for crushing slag. Background technique [0002] The winter in the northern part of my country is cold, lasting for 3 to 6 months, especially in the vast rural areas, where some urban central heating pipe networks cannot reach. Therefore, indoor heating is mainly based on coal. Now indoor boilers are used, although they can also meet the heating needs at the same time, but the heating furnace used directly discharges all the dust and smoke generated by combustion outside through the chimney, and does not make full use of the heat energy of high-temperature flue gas. , the thermal energy utilization efficiency is low, resulting in serious energy waste; in addition, after the coal is burned internally for a period of time, due to the large amount of slag, the internal coal cannot be fully burned, which also leads to low fuel utilization, and it is difficult t...

[0002] The winter in the northern part of my country is cold, lasting for 3 to 6 months, especially in the vast rural areas, where some urban central heating pipe networks cannot reach. Therefore, indoor heating is mainly based on coal. Now indoor boilers are used, although they can also meet the heating needs at the same time, but the heating furnace used directly discharges all the dust and smoke generated by combustion outside through the chimney, and does not make full use of the heat energy of high-temperature flue gas. , the thermal energy utilization efficiency is low, resulting in serious energy waste; in addition, after the coal is burned internally for a period of time, due to the large amount of slag, the internal coal cannot be fully burned, which also leads to low fuel utilization, and it is difficult to clean the internal slag, so , it is necessary to improve the existing heating boilers to solve the above problems
