Thermal expansion structure of joint part of garbage incinerator

Abstract

The invention relates to a thermal expansion structure of a joint part of a garbage incinerator. The structure is adaptable to the joint part between a fixed end and a thermal expansion end. By the adoption of the structure, all components of the garbage incinerator can slide down freely without interference within a certain temperature range during operation, and sealing performance can be guaranteed. According to the technical scheme, the structure comprises a steel frame, a thermal expansion component, a fixed component and a heat insulating and sealing structure, the thermal expansion component and the fixed component are supported by the steel frame, and the heat insulating and sealing structure is arranged on the joint part between the thermal expansion component and the fixed component. The structure is characterized in that a shelf is fixed to the thermal expansion component, round steel is arranged on the top of the shelf, a cover plate is installed on the fixed component, the bottom surface of the front portion of the cover plate is in contact with the round steel, and the front end of the cover plate is spaced from the thermal expansion component.

Description

technical field [0001] The present invention relates to the technical field of waste incinerators, and specifically relates to the thermal expansion structure of the joint part of the waste incinerator, comprehensively considering the different thermal expansion requirements of different parts of the incinerator, so that the expansion parts of the incinerator can slide freely during operation without interfering with each other. At the same time, the airtightness of the furnace body can be guaranteed. Background technique [0002] In waste incinerators, sealing and thermal expansion are issues that need to be considered from time to time. Whether the solution to the thermal expansion problem is reasonable or not directly affects the safety of incinerator operation and on-site sanitation. [0003] The domestic waste incinerator provided by Chinese Patent No. 02111455.2 includes a furnace body with a hopper, a feeder installed in the furnace body, a fire grate, an air chamber ...

AI Technical Summary

Problems solved by technology

Due to failure to deal with the thermal expansion relationship between reverse push and forward push well, the junction is prone to dust leakage and causes pollution to the working environment on site

[0004] In the two-stage domestic waste incinerator with an adjustable material layer provided by Chinese Patent No. 200610052844.6, there are also thermal expansion and sealing problems in the junction between the reverse push grate and the forward push grate, and between the forward push grate and the slag discharge channel. contradictory question
