Detailed Description

The specific structure and operation of the present invention will be further described with reference to the accompanying drawings.

As shown in the figure, the automatic feeding ash removal device for the bundle burning boiler comprises a power system 1, a feeding system 2, an ash removal system 3 and a combustion system 4.

The power system 1 comprises a forklift 101, a distance sensor 102 and a hydraulic machine 103. Wherein the forklift 101 is connected with the retainer plate 204; the reservoir 304 is fixed to the forklift. The hydraulic machine 103 is integrated with the front end of the forklift, and a hydraulic push rod at the front end of the hydraulic machine is connected with the feeding push plate 201; when the straw bundle is fed, the forklift moves backwards, the push rod of the hydraulic press pushes forwards, the distance sensor identifies the pushing distance of the hydraulic push rod, and the pushing process of the straw bundle is determined, so that the process of cleaning ash during feeding is controlled.

The feeding system 2 comprises a feeding push plate 201, a limiting plate 203 and a retainer plate 204. The limiting plates 203 are designed on two sides of the material supporting plate and are integrated with the material supporting plate; the height of the feeding push plate is consistent with that of the furnace door, and the ash is removed by sealing; the retainer plate is designed to be hollow, and holes 205 are formed in the retainer plate 204. The straw bundles 202 are stacked on the material supporting plate and fixed through the material loading push plate and the limiting plate, so that the straw bundles are prevented from inclining and falling; during feeding, the forklift retreats to drive the material supporting plate and the limiting plate to retreat, the hydraulic push rod pushes forwards to enable the feeding push plate to be located outside the furnace door all the time, and finally straw bundles fall into a boiler combustion chamber.

The trigger 3011 is connected in a slot type connection as shown in fig. 3, and the top of the trigger 3011 is inserted into the slot 3012. When the material supporting plate completely extends into the hearth, the trigger device on the ash cleaning plate touches the inner wall of the hearth, so that the front end of the trigger device leaves from the groove on the ash cleaning plate, and the ash cleaning plate descends to the bottom of the hearth under the action of gravity; the ash chamber 303 is integrated with the feeding push plate 201 and moves along with the feeding push plate, and the ash chamber is always positioned outside the furnace door in the feeding process and keeps relatively static. The ash and slag are stored in the ash and slag chamber, so that the ash and slag are in a closed environment, the generation of dust in the collecting and transporting process is avoided, and the ash and slag chamber is convenient to collect, stack and recycle.

The scraper 3013 of the inboard downward sloping of deashing board, the scraper is established into the inclined plane, gives consideration to the function of broken sediment, shovels out the lower part lime-ash of furnace easily and is difficult for making the deashing board warp the fracture. The ash cleaning plate is made of high-temperature resistant soft materials, so that the furnace wall is prevented from being damaged during ash cleaning.

The ash cleaning system comprises an ash bottom plate 305 and an ash chamber 303, wherein the ash chamber 303 is fixed below the feeding push plate 201, and the ash bottom plate 305 is arranged at the bottom of the combustion system 4 and is positioned below the retainer plate 204. The ash chamber 303 is integrated with the feeding push plate 201. The two sides of the ash bottom plate 305 are connected with side plates 2023 through fireproof hinges 2021 and buckles 2022, the bottom of the ash chamber is connected with the side surfaces through the fireproof hinges and the buckles to be movable, and therefore ash stored in the ash chamber can be cleaned conveniently.

The water spray holes are arranged below the retainer plate, and the water spray holes 302 are connected with a water storage tank 304. The water spray holes in the material supporting plate are opened during feeding at each time to wet ash, dust is prevented from being raised, sparks which are not completely burnt out are prevented from being generated, and the water spray holes in the ash chamber are opened to wet the ash after the ash enters the ash chamber, so that the dust is prevented from being raised, and the ash is convenient to clean.

The combustion system 4 of the utility model mainly comprises a fan 401, a hearth 402 and a smoke outlet 403. The straw bundle is combusted in the hearth under the appropriate air distribution quantity given by the fan, and the generated smoke is discharged into the air after being dedusted through the smoke outlet.

The working principle and the process are as follows: when the equipment normally operates, the straw bundles are stacked on the material supporting plate when the intermittent boiler works, the water level of the water storage tank is checked, and the water quantity is sufficient during dust removal. When the boiler combustion chamber is burnt out, a furnace door is opened, a forklift is started to adjust the material supporting plate to a proper height so that the straw bundle smoothly extends into the combustion chamber of the hearth, and meanwhile, water spray holes are opened to extinguish the unburned sparks and wet ash residues so as to prevent the generation of raised dust and fly ash; when the straw bundle completely extends into the combustion chamber of the hearth, the ash cleaning plate automatically opens the locking switch and lowers to the bottom of the hearth to start ash cleaning; at the moment, the forklift moves backwards, the hydraulic push rod pushes forwards, so that the feeding push plate and the ash chamber are always positioned outside the furnace door, the straw bundle smoothly falls into a combustion chamber of the furnace through the thrust of the hydraulic machine on the feeding push plate, the ash cleaning plate pushes ash in the furnace outwards while moving backwards along with the forklift, and finally the ash falls into the ash chamber.
