Problems solved by technology

Because the temperature difference of the running chain changes greatly during the whole operation cycle, under the action of long-term high temperature difference, torsion force and friction force, the inner sleeve of the chain link that has a slight amount of enjoyment with the chain link will move outward to the side with a slightly higher temperature, thus ...

Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings.

[0018] Such as figure 1 , figure 2 , image 3 , Figure 4 The chain grate chain link manufacturing method for preventing the inner cover from scurrying outside includes the following steps:

[0019] a. Select a joint 2 with two joint through holes 21, and an inner sleeve 1 with an inner sleeve through hole 11 inside, and chamfer the outer edge of the end of the inner sleeve 1 to obtain the inner sleeve chamfer 12. Connect the chamfered inner sleeve 1 to one of the through holes 21 of the joint section 2;

[0020] b. Select welding rods to weld the inner sleeve chamfer 12 of the inner sleeve 1 to obtain the inner sleeve anti-off ring 3, and the inner sleeve anti-off ring 3 prevents the inner sleeve 1 from moving to the inner sleeve chamfer 12 side;

[0021] c. Repeat the above two steps cyclically, connect two adjacent joints 2 together through the inner sleeve 1 ...

Abstract

The invention relates to the field of chain grate machine equipment which is applied to production of rotary kiln pellets, particularly to a chain grate machine chain link production method for preventing inner sleeves from being out. The chain grate machine chain link production method comprises the following steps of step a, selecting a chain link and an inner sleeve, performing chamfering on the outer edge of the end of the inner sleeve to obtain an inner sleeve chamfer and connecting the chamfered inner sleeve with one of chain link through holes of the chain link in a sleeving mode, wherein the chain link is provided with two chain link through holes and an inner sleeve through hole is formed in the inner sleeve; step b, performing welding on the inner sleeve chamfer of the inner sleeve to obtain an inner sleeve anti-falling ring; step c, repeating the step a and the step b in a circulating mode, enabling the inner sleeve chamfers of the inner sleeves to be towards the same side of direction and enabling the chain links to be snapped into a closed annular shape from head to tail to obtain a chain. The chain grate machine chain link production method for preventing the inner sleeves from being out is particularly suitable for the production situation which can result in outgoing of the inner sleeves due to the large chain running environment temperature difference.

Description

technical field [0001] The invention relates to the field of grate equipment used for the production of pellets in a rotary kiln, in particular to a method for manufacturing a chain link of the grate for preventing inner sleeves from moving outside. Background technique [0002] During the normal production process of the rotary kiln pelletizing process using the grate machine, the operating chain of the grate machine will experience a harsh working environment with a temperature difference of 1100 °C from normal temperature to the machine head. The pellets are continuously transported to the rotary kiln. Because the temperature difference of the running chain changes greatly during the whole operation cycle, under the action of long-term high temperature difference, torsion force and friction force, the inner sleeve of the chain link that has a slight amount of enjoyment with the chain link will move outward to the side with a slightly higher temperature, thus As a result,...
