Description

Technical Field

[0001] The utility model relates to the field of boiler doors, in particular to a door structure of a biomass boiler. Background Art

[0002] Boiler glass refers to the transparent material installed on the observation hole or window of the boiler to observe the working conditions inside the boiler. In order to increase the strength and heat resistance of the glass, a layered design is often used.

[0003] After searching, the patent announcement number is CN203731477U, which discloses a device for opening and closing boiler doors, including a motor and a block matched with the boiler door, the boiler door is provided with a motor, the motor is fixed on the boiler door, the motor is equipped with a transmission rod, the transmission rod is connected to the block, the transmission rod and the door are swivel connected, the block is connected to a restraining rod, the other end of the restraining rod is relatively fixed to the boiler door frame, the block and the restraining rod are swivel connected, and the swivel axes of the swivel connection between the transmission rod and the block and the swivel connection between the block and the restraining rod are parallel to each other. The utility model can accurately and safely open and close the boiler door. By adjusting the motor speed, the effect of opening and closing the furnace door at different speeds is achieved, and the operation is simple, the effect is obvious, and manpower is saved. The structure is simple and compact, easy to carry, and the cost is low.

[0004] The existing technology can be used, but there are defects: the existing biomass boiler door lacks the problem of self-cleaning inner wall and lacks effective safety protection effect, resulting in the door body not achieving the best protection function when an accident occurs. In view of this, we propose a biomass boiler door structure to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to propose a furnace door structure of a biomass boiler in view of the problems existing in the background technology.

[0006] The technical solution of the utility model is: a furnace door structure of a biomass boiler, including a plate body, a glass body, a rotating frame and two springs, a positioning groove is arranged inside the plate body, a glass body is installed inside the positioning groove, a mounting seat is arranged on one side of the plate body, a rotating frame is rotatably installed on the upper end of the mounting seat through a rotating shaft, and two springs are installed inside the glass body.

[0007] When using a furnace door structure of a biomass boiler in the present solution, the device can use external bolts and positioning holes to fix the mounting base on one side of the boiler door body, and then the plate body can be rotated around the bracket and the mounting base rotation center to achieve opening and closing. The device can use the glass body to view the inside from the outside. After burning for a period of time, the inner wall of the glass body may be blurred and block the line of sight. At this time, the motor can be started to drive the scraper at the lower end of the rotating frame that is always in contact with the inner wall of the glass body to scrape off stains to ensure a good visual environment. In addition, an explosion-proof layer of glass with a buffering effect is arranged inside the glass body. Even after the fire-resistant layer of glass explodes, the explosion-proof layer of glass will move down a distance under the buffering action of the second spring, and then use the hardness of the explosion-proof layer of glass itself to resist the explosion, thereby achieving a double-layer protection effect.

[0008] Preferably, a handle is provided on one side of the plate body.

[0009] Preferably, a bracket is provided on one side of the plate body, a mounting seat is rotatably mounted between the brackets, and a positioning hole is provided at the bottom of the mounting seat.

[0012] Preferably, an installation groove is provided on an outer wall of one side of the plate body, a motor is provided inside the installation groove, and an output shaft of the motor is fixedly connected to one end of the rotating shaft.

[0013] Preferably, the outer layer of the vitreous body is provided with a fire-resistant layer of glass, the inner layer of the fire-resistant layer of glass is provided with a movable explosion-proof layer of glass, the inner wall of the vitreous body is provided with a mounting block, and the second spring is installed between the mounting block and the explosion-proof layer of glass.

[0014] Compared with the prior art, the advantages of the present invention are:

[0015] 1. The utility model can utilize a scraper with an inner glass cleaning effect to clean the inner wall of the glass, thereby always ensuring a good visual observation effect.

[0016] 2. Based on the first beneficial effect, the device is provided with an explosion-proof layer of glass with a buffering function inside the glass body, which has a double explosion-proof effect and optimizes safety.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
