Description

Technical Field

[0001] The utility model relates to the technical field of incinerators, in particular to a fixed grate piece of a garbage incinerator. Background Art

[0002] Fixed grate is an important component used in equipment such as industrial boilers and waste incinerators. It is mainly used to support and fix the grate to facilitate the combustion of fuel and the discharge of ash. Fixed grate is usually made of cast iron or other high-temperature resistant materials with good wear resistance and corrosion resistance.

[0003] Announcement No. CN215982578U discloses a fixed grate plate for a waste incinerator. Ventilation holes penetrate the upper and lower surfaces of the fixed grate plate of the waste incinerator, allowing cooling air from the bottom of the grate plate body to flow to the top of the grate plate body through the above-mentioned vents, thereby making the air distribution above the grate plate uniform, thereby improving the waste combustion rate and avoiding uneven burning.

[0004] The fixed grate plate of the garbage incinerator passes through the upper and lower surfaces of the fixed grate plate of the garbage incinerator through the air vents, so that the cooling air below the grate plate body can flow to the top of the grate plate body through the above-mentioned vents, thereby making the air distribution above the grate plate uniform. However, the vents are located in the middle of the grate plate. Since garbage is accumulated on the upper surface of the grate plate, it is difficult for the cooling air to diffuse to the two sides of the grate plate, resulting in poor ventilation effect on both sides of the upper surface of the grate plate, thereby affecting the incineration efficiency. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a fixed grate plate for a garbage incinerator.

[0006] The utility model is implemented by the following technical scheme: a fixed grate piece of a garbage incinerator comprises a grate piece, the bottom of the grate piece is fixedly connected with a lower rib plate, the right end of the lower rib plate is fixedly connected with a reinforcing plate, the inner wall of the reinforcing plate is provided with a mounting hole, the inner wall of the reinforcing plate is provided with a through groove, the upper surface of the grate piece is provided with a ventilation opening, the upper surface of the grate piece is provided with a plurality of ventilation holes, the inner wall of the lower rib plate is provided with a ventilation groove, the bottom of the grate piece is fixedly connected with an auxiliary fixing plate, and the left end of the auxiliary fixing plate is fixedly connected with a scraper.

[0007] Through the above technical solution, the cooling air below the grate plate enters the ventilation port through the through slot and is discharged to the top of the grate plate, ensuring that the garbage can be fully burned. At the same time, part of the cooling air enters the position of the fixed plate through the ventilation slot, and the rectangular slot opened in the fixed plate allows the cooling air to be discharged to the top of the grate plate through the ventilation hole, further improving the incineration efficiency of the garbage. The installation holes opened on the inner wall of the reinforcement plate facilitate the splicing of multiple grate plates.

[0008] As a further improvement of the above solution, the left end of the grate piece is bent downward, the right end of the grate piece is bent upward, and the through groove is communicated with the vent.

[0009] Through the above technical solution, multiple through slots and ventilation slots are provided, which improves the ventilation efficiency and ensures that the garbage can be fully burned.

[0010] As a further improvement of the above solution, the top of the reinforcing plate is fixedly connected to the bottom of the grate plate.

[0011] As a further improvement of the above solution, there are four reinforcing plates, and the four reinforcing plates are symmetrically distributed with the grate plate as the center.

[0012] Through the above technical solution, additional supporting force is added to the grate pieces through multiple reinforcing plates, thereby improving the bearing capacity of the grate pieces and thus improving the stability of the structure.

[0013] As a further improvement of the above solution, the auxiliary fixing plate is located at the left end of the lower rib plate, and a rectangular groove is provided on the inner wall of the auxiliary fixing plate.

[0014] Through the above technical solution, the structural stability of the grate plate is ensured by connecting the lower rib plate with the reinforcing plate.

[0015] As a further improvement of the above solution, a baffle is fixedly connected to the left end of the lower rib plate, and one end of the baffle away from the lower rib plate is fixedly connected to the inner wall of the grate plate.

[0016] As a further improvement of the above solution, there are two baffles, which are symmetrically distributed around the grate plate.

[0017] Through the above technical solution, the two baffles shield the two sides of the grate piece, preventing garbage on both sides from falling into the interior of the grate piece.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] The utility model provides a reinforcing plate, a through groove, a vent, a ventilation hole and a ventilation slot. Specifically, the cooling air below the grate plate enters the ventilation slot through the through groove and is discharged to the top of the grate plate, thereby ensuring that the garbage can be fully burned. At the same time, part of the cooling air enters the position of the fixed plate through the ventilation slot, and the rectangular slot opened in the fixed plate allows the cooling air to be discharged to the top of the grate plate through the ventilation hole, thereby further improving the incineration efficiency of the garbage.

[0020] The utility model provides additional supporting force by arranging lower rib plates and reinforcing plates, specifically through the lower rib plates and reinforcing plates at the bottom of the grate plates, thereby ensuring the structural stability of the grate plates and extending their service life. The mounting holes opened on the inner walls of the reinforcing plates facilitate splicing multiple grate plates. BRIEF DESCRIPTION OF THE DRAWINGS
