Embodiment Construction

[0029] The chain grate machine is to place the iron-containing material balls on the slow-moving grate plate, and use the waste heat of the annular cooler and the hot air flow discharged from the rotary kiln to dry the raw balls (which can be divided into a drying section and a drying section), The preheating section (which can be divided into the temperature adjustment preheating section and the preheating section), and then directly sent to the rotary kiln for roasting.

[0030] The mounting device for supporting rollers on the chain grate machine includes several supporting roller shafts, and several supporting rollers installed on each supporting roller shaft. The chain grate device in the chain grate machine can drive the supporting wheel of the supporting wheel device to rotate during the movement.

[0031] see figure 1 , which is a front view of the installation device for the supporting roller on the grate according to the embodiment of the present invention.

Abstract

A chain grate upper supporting wheel installation device comprises a supporting wheel shaft, a plurality of spacing mechanisms fixedly arranged on the upper supporting wheel shaft and supporting wheels with the same number of the spacing mechanisms, wherein the supporting wheels are limited by the corresponding spacing mechanisms, and each spacing mechanism comprises an axial limited block which is arranged on the supporting wheel shaft and used to limit the corresponding supporting wheel to move axially along the supporting wheel shaft direction and a circumferential limited block which is arranged on the supporting wheel shaft and used to limit the corresponding supporting wheel to move circumferentially along the supporting wheel shaft direction. The invention provides the chain grate upper supporting wheel installation device so as to reduce the processing difficulty and production cost of the upper supporting wheel shaft.

Description

technical field [0001] The invention relates to a chain grate, in particular to a mounting device for a supporting wheel on a chain grate. Background technique [0002] In the prior art, there are mainly three methods for preparing pellets, namely: the method of producing pellets in a shaft furnace, the method of preparing pellets by a belt roaster, and the method of preparing pellets by a chain grate-rotary kiln method. Compared with the other two methods, the grate machine-rotary kiln method has many advantages such as good product quality, large single-machine production capacity, and suitable for large-scale production, so it is widely used. [0003] The chain grate machine is to place the iron-containing material balls on the slow-moving grate plate, and use the waste heat of the annular cooler and the hot air flow discharged from the rotary kiln to dry the raw balls (which can be divided into a drying section and a drying section), The preheating section (which can be...
