Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of boiler dust removal devices, in particular to a boiler dust removal device. BACKGROUND

[0002] A boiler is an energy conversion device that primarily heats water or other fluids by burning fuel or using electrical energy to produce steam or high-temperature water, which then provides thermal energy or converts it into mechanical energy. A boiler consists of two parts: the "pot" is the pressure-containing component that holds water and steam, while the "furnace" is where the fuel is burned. Boilers can convert mechanical energy into electrical energy through steam power devices or convert mechanical energy into electrical energy through generators.

[0003] The existing invention patent with the publication number "CN220135491U" is named a boiler dust removal device, which includes a boiler body, a support plate is arranged on one side of the top surface of the boiler body, a fixed plate is arranged on the top surface of the support plate, a moving box is connected to the top surface of the fixed plate in a sliding manner, a drive motor is arranged on the top inner wall of the moving box, an electric telescopic rod is arranged on the output end of the drive motor, a dust collector is arranged on one side of the outer circle of the output end of the electric telescopic rod, a rotating block is arranged at the bottom end of the electric telescopic rod, and a plurality of groups of brushes are uniformly arranged on the outer circle of the rotating block. The boiler dust removal device can clean the dust on the inner wall of the smoke exhaust pipe through the rotating block, the brushes and the drive motor, and can suck the cleaned dust through the dust collector, avoiding the emission of dust in the smoke exhaust pipe into the air to pollute the air, and avoiding the time-consuming and laborious manual cleaning.

[0004] The inventor believes that the brush only cleans the smoke exhaust pipe, and does not clean the inside of the boiler body, which has certain limitations. The inner wall of the boiler will not be cleaned for a long time due to the burning object, which will cause insufficient fuel combustion. In addition, the existing brush is placed in the boiler, and the burning cannot be effectively protected. Therefore, a boiler dust removal device is needed. SUMMARY

[0005] The purpose of the present application is to solve the problems in the prior art and provide a boiler dust removal device.

[0006] In order to achieve the above purpose, the present application adopts the following technical scheme:

[0010] Preferably, the reset component comprises a pair of first telescopic rods rotationally connected to the inner walls of the first brush plate and the third brush plate, the inner wall of the first telescopic rod is rotationally connected with a driving shaft, and one end of the pair of driving shafts is fixedly connected to the inner walls of the second brush plate and the fourth brush plate respectively.

[0011] Preferably, the surface of the first telescopic rod is fixedly connected with a first connecting block and a second connecting block, the surface of the first telescopic rod is sleeved with a first spring, one end of the first spring is fixedly connected to the surface of the first connecting block, and the other end of the first spring is fixedly connected to the surface of the second connecting block.

[0012] Preferably, the surface of the rotating plate is slidably connected with a pair of L-shaped plates, and the opposite surfaces of the pair of L-shaped plates are fixedly connected with trapezoidal baffles.

[0013] Preferably, the surface of the rotating plate and the L-shaped plate is fixedly connected with the same second telescopic rod, the surface of the second telescopic rod is sleeved with a second spring, one end of the second spring is fixedly connected to the surface of the L-shaped plate, and the other end of the second spring is fixedly connected to the surface of the rotating plate.

[0014] Preferably, the cleaning component comprises a U-shaped cleaning pipe fixedly connected to the surface of the rotating plate, a plurality of push plates are fixedly connected to the surface of the U-shaped cleaning pipe, and a plurality of water outlets are formed in the inner wall of the U-shaped cleaning pipe.

[0015] Preferably, the inner walls of the rotating plate and the drive shaft are provided with the same water feeding groove, and the water feeding groove is in communication with the inner wall of the U-shaped cleaning pipe.

[0016] Preferably, the surface of the drive shaft is rotationally connected with a fixed ring, the fixed ring is fixedly connected with a pair of O-shaped sealing rings on the abutting surface of the drive shaft, the inner wall of the fixed ring is fixedly connected with a water inlet pipe, the surface of the water inlet pipe is fixedly connected with a water pump, and one side of the water pump is fixedly connected to the surface of the boiler body.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. During dust removal, the first and third brush plates rotate out from the rotating plate via a high-temperature resistant figure-eight belt. When the first brush plate is perpendicular to the inner wall of the boiler body, the surface of the second brush plate and the surface of the fourth brush plate are also in contact with the inner wall of the boiler body. The rotation of the drive shaft drives the second and fourth brush plates to rotate as a whole through the rotating plate. At this time, the cleaning water in the U-shaped cleaning pipe is sprayed out through multiple water outlets, working in conjunction with the second and fourth brush plates to clean the inner wall of the boiler body. The advantage of this is that the cleaning of the inside of the boiler body can be achieved without opening the boiler body.

[0021] 2. After cleaning is completed, the second and fourth brush plates can be rotated and stored inside the rotating plate. The second spring drives the L-shaped plate to slide back to its original position, which in turn drives a pair of trapezoidal baffles to seal and protect the opening of the rotating plate, so that the high temperature of combustion will not damage the second and fourth brush plates, making it easier for the next cleaning operation.
