[0002] The boiler hood is an important component in the boiler equipment. It mainly has the following functions: it can evenly distribute the air entering the boiler, ensure the full combustion of the fuel, and help avoid the local accumulation of fuel in the furnace to form coking.

[0003] When a common boiler hood is used for a long time, long-term vibration can easily cause the connection of the boiler hood to become loose, which can cause the boiler hood to leak and fall off. In addition, the number of air outlet holes on a general boiler hood is fixed. When personnel need to adjust the air outlet speed of the air outlet holes, they need to replace the boiler hood with a different number of air outlet holes, which is troublesome. In view of this, we propose a shockproof boiler hood. Utility Model Content

[0010] In the present technical solution, by means of the setting of the limiting assembly, a person can insert the bottom end of the hood body into the card slot on the air inlet pipe until the bottom end of the hood body rests on the buffer pad. At this time, the limiting assembly can limit the hood body. When the whole device vibrates, the second spring will always squeeze the card block so that one end of the card block will not fall off from the air inlet pipe, ensuring that the hood body will not become loose due to the vibration and that the hood body will not fall off from the air inlet pipe without the action of external force. At the same time, under the buffering action of the buffer pad, it can be ensured that the hood body is subjected to less vibration.

[0011] Through the setting of the fixing component, the fixing component can release the limit of the annular plate, and the personnel can move the slider downward, and the slider will drive the annular plate to move downward in the annular groove. The personnel can use the annular plate to cover the unnecessary through holes according to the required number of through holes. At this time, the fixing component can limit the annular plate to ensure that the personnel can adjust the output of the through holes according to the required air outlet amount, and there is no need for personnel to replace the hood body with different numbers of through holes, which is convenient for personnel to operate.

[0014] In the present technical solution, the spring block is pressed, and the spring block moves in the circular groove and squeezes the spring to contract until one end of the spring block completely enters the circular groove. At this time, the spring block can release the limit on the annular plate, and the personnel can move the slider downward, and the slider will drive the annular plate to move downward in the annular groove. The personnel can use the annular plate to cover the unnecessary through holes according to the required number of through holes. At the same time, under the action of the rebound force of the spring, the spring will squeeze the spring block to move outward until one end of the spring block is inserted into one of the limit grooves. At this time, the spring block can limit the annular plate, ensuring that the personnel can adjust the output of the through holes according to the required amount of air outlet, and there is no need for the personnel to replace the hood body with different numbers of through holes, which is convenient for the personnel to operate.

[0018] Two rectangular grooves are symmetrically arranged on the peripheral side of the hood body and are located in the card slots. A card block is slidably installed in the rectangular groove. One end of the card block passes through one side of the rectangular groove and the air intake pipe. The other end of the card block is fixedly installed with a spring 2 fixed to the inner wall of the rectangular groove.

[0019] In the present technical scheme, when in use, first press the two blocks to make the blocks move inward in the rectangular groove.

At this time, under the action of the rebound force of the spring two, the spring two will squeeze the block to move outward until one end of the block is inserted into the intake pipe. At this time, the block can limit the hood body. When the whole device vibrates, the spring two will always squeeze the block so that one end of the block will not fall off the intake pipe, ensuring that the hood body will not loosen due to vibration, and ensuring that the hood body will not fall off the intake pipe without the action of external force. At the same time, under the buffering action of the buffer pad, it can be ensured that the hood body is subjected to less vibration.
