Problems solved by technology

[0002] At present, domestic orange stalks are burned in the open air, causing serious pollution to the air environment. Through the biomass power generation project, this phenomenon has been curbed, but the combustion conditions of biomass power generation are different, and straw, wood chips, etc. are especially harmful to the return box wear, Corrosion and damage are serious, which increases the operating cost of power generation and shortens its service life

Embodiment 1

[0009] Example 1: A high-temperature anti-blocking and resistant porcelain block, including a rectangular ceramic block 1 with a thickness of 18 mm, a metal shell 2 with a thickness of 4 mm, and the rectangular ceramic block 1 is embedded in the metal shell 2. The diameter of the surface of the rectangular ceramic block 1 is The through hole 1.1 is 22mm~25mm. The inner surface of the metal shell 2 corresponds to the through hole 1.1 on the surface of the rectangular ceramic block 1. There is a boss 2.1 with a diameter of 8~10mm, and the height of the boss 2.1 is less than 18mm. Convex balls 2.1.1 with a diameter of 2 mm are arranged at intervals on the side walls of the convex posts 2.1. The wear-resistant castable 3 is poured into the through hole 1.1, and the outer surface of the side wall of the metal shell 2 is provided with a strip-shaped bump 2.2 for matching with the adjacent metal shell 2 and a strip-shaped groove 2.3 matched with the strip-shaped bump 2.2 , the height...

Abstract

A high-temperature anti-blockage resistance ceramic block comprises rectangular ceramic block bodies with the thickness of 18 mm and a metal shell with the thickness of 4 mm. The rectangular ceramic block bodies are embedded in the metal shell in a connected manner. A through hole with the diameter ranging from 22 mm to 25 mm is formed in the surface of each rectangular ceramic block body. A protruding column corresponding to the through hole in the surface of each rectangular ceramic block body is arranged on the inner surface of the metal shell, wherein the diameter of each protruding column ranges from 8 mm to 10 mm, and the height of each protruding column is smaller than 18 mm. The structure is simple, installing is firm, and cracking and disengaging are effectively prevented.

Description

technical field [0001] The invention relates to the field of biomass power generation incinerators, in particular to a ceramic block for a return box of a biomass power generation incinerator. Background technique [0002] At present, domestic orange stalks are burned in the open air, causing serious pollution to the air environment. Through the biomass power generation project, this phenomenon has been curbed, but the combustion conditions of biomass power generation are different, and straw, wood chips, etc. are especially harmful to the return box wear, Corrosion and damage are serious, which increases the operating cost of power generation and shortens its service life. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides a high-temperature anti-blocking ceramic block with simple structure, firm installation, and effective prevention of cracking and falling off. [0004] In order to achieve the purpose of the present i...
