AI Technical Summary

Problems solved by technology

The existing supporting device is composed of a base, a shaft, a ball bearing and a roller. The gap between them is very small. After the ball bearing undergoes thermal expansion, there is no gap. The grate has changed from the previous rolling transmission to the sliding transmission, and the resistance is intensified, even causing the fixed base of the grate stretching mechanism to be pulled up, forcing the grate to be shut down for maintenance, resulting in shutdown of the furnace

Embodiment 1

[0013] Embodiment 1 In FIG. 1, a grate support device includes a base 9, a shaft 3, and a drum 1. The shaft 3 is installed on the base 9 through a shaft seat bolt 6, and the shaft 3 is covered with a drum 1; it is characterized in that: the drum 1 A shaft sleeve 2 is arranged for internal fastening, and the inner gap of the shaft sleeve 2 is sleeved with the shaft 3 . The gap in the shaft sleeve sleeve shaft is 0.3-0.5mm, so that the shaft and the shaft sleeve can fully rotate.

Embodiment 2

[0014] Embodiment 2 A grate support device, the shaft 3 is provided with a groove 11 for placing a non-oil lubricant. The groove is an axial threaded groove with a width of 2 mm and a depth of 2 mm. Add non-oil lubricants (such as lead powder, graphite powder) to solve the problem of large friction; and change the material of the shaft sleeve from the original copper to 45#, so that the shaft sleeve has a longer service life. It is a good solution that the support wheel will not stop rotating due to heat, it will only make it more flexible as it grinds, and the grate will not be unable to operate due to the non-rotation of the support wheel, thereby avoiding the occurrence of the furnace shutdown problem. All the other are with embodiment 1.

Embodiment 3

[0015] Embodiment 3 A grate support device, in which a groove for non-oil lubricant is arranged on the inner wall of the shaft sleeve 2 . The groove is an axial threaded groove with a width of 2 mm and a depth of 2 mm. All the other are with embodiment 1.

Abstract

A furnace support device comprises the base, shaft, roller installed outside the shaft that installed on the base through a shaft base bolt. Non oil lubricant is applied on the shaft to reduce friction. It can also put non oil lubricant inside the slot. In order to keep the roller and the axial sleeve tight, it seals the cover at both ends through fixed bolt with stuffed press shaft sleeve.There is also protective shaft cushion between the bottom base and the seal cover. Due to the support device under the furnace, it solves the friction issue of the support wheel with it more and more flexible. It is good in sliding, big in loading and simple in structure.

Description

technical field [0001] The invention relates to a fire grate support device, in particular to a fire grate support device for a vertical domestic garbage thermal decomposition incinerator. It is used in incinerators in energy and environmental protection equipment to incinerate low calorific value, high moisture, and unsorted domestic waste to generate electricity. Background technique [0002] With the development of modern production, the increase of urban population and the improvement of consumption level, the generated garbage pollutes the environment and causes social public hazards, which has already attracted the attention of all countries. At present, there are two major types of municipal solid waste treatment methods, namely, incineration and sanitary landfill. The latter occupies a large amount of land and its leachate pollutes more groundwater, and the landfill causes secondary pollution to the surrounding environment. Most foreign countries use waste incinerat...
